    Introduction

    Hyperthermia can cause infertility in men following an increase in testicular temperature. Oxidative stress has been found to be one of its major causes. In the present study, the effects of iron superoxide nanoparticles on the expression of Bcl-2 and Bax family genes were studied.

    Materials and Methods

    A total of 48 adult rats were purchased from the Pasteur Institute of Iran. The rats were later divided into 4 groups: control group, control group receiving superoxide nanoparticles (Fe2O3), hyperthermia group, h’:yperthermia group receiving superoxide nanoparticles (Fe2O3). After RNA extraction, evaluating the sperm parameters and the expression of Bax and Bcl-2 genes was examined using RT-PCR technique.

    Results

    Exposure to iron superoxide nanoparticles (Fe2O3) decreased sperm parameters, increased proapoptotic BAX gene and decreased expression of BCL2 anti-apoptotic gene.

    Conclusion

    Exposure to nanoparticles by reducing sperm parameters and increasing apoptosis has a negative effect on fertility. The association between infertility and testicular hyperthermia is becoming increasingly apparent; administration of iron superoxide (Fe2O3) nanoparticles can have significant effects on male infertility. Moreover, green synthesis of nanoparticles is also recommended in this field.

    Introduction

    Despite the improvements in antiretroviral treatments, there is no authorized HIV vaccine; therefore, designing an effectual vaccine is essential. This study was aimed at the immunological evaluation of HIV-1 p24-Nef adjuvanted with IFN-γin BALB/c mice with the purpose of stimulating effective immune responses.

    Materials and Methods

    Forty-eight female mice were used for immunization by p24-Nef. The mice were divided into six cohorts with eight mice in each group. Immunizations were executed three times at three-week intervals and subcutaneously for 5μg per mouse. A couple weeks after the last injection, humoral and cellular immune pathways were appraised in blood serum and splenocytes respectively through applying ELISA.

    Results

    The results showed that the applied regimen could elicit robust immune responses in comparison with the control. In addition, the level of total antibody production which was observed in the group containing adjuvanted antigen of interest had a significant difference with the control cohort (P<0.0001). Moreover, IgG2a was the uppermost isotype (Th1-biased response) in the immunized group that had p24-Nef antigen with IFN-γ adjuvant. In spite of antibody secretion, the cellular immune response was the predominant stimulated pathway. The potency of IFN-γ as an adjuvant for induction of a quantifiably extensive Th1 pathway was shown to be more significant given the outcomes of cytokine assay, IgGisotype, and CTL evaluation.

    Conclusion

    The results of the current study indicated that the p24-Nef antigen is able to stimulate the humoral and cellular immune responses in immunized mice, either on its own or when formulated with adjuvant. Thus, the high immune system stimulated by p24-Nef injection regimen went along with IFN-γ adjuvant, offering a potential option for an efficient vaccine against HIV-1.

    Introduction

    Coronavirus Disease (COVID-19) caused by Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2) was first discovered in China in late 2019 and spread rapidly worldwide. This study aimed to correlate positive real time Reverse Transcriptase Polymerase Reaction (RT-PCR) results after one month of follow-up with laboratory findings of the same patients at hospital admission to predict clinical outcome and diagnosis.

    Materials and Methods

    We conducted a retrospective study on the laboratory findings of 299 adult patients suspected of COVID-19. Patients were admitted to hospital from March 21 to May 25, 2021 with final follow-up of one month for each patient. After one month of follow-up, 233 patients recovered; however, in 64 patients the symptoms worsened. For these patients RT-PCR was performed and some patients needed chest Computed Tomography (CT) imaging and were hospitalized. We extracted laboratory findings of these 64 patients and correlated the results of their RT-PCR with their laboratory findings.

    Results

    Based on our findings, severe cases are middle-aged adults (P=0.001) with lymphopenia (P<0.001), decreased levels of white blood cells (WBCs) (P<0.001), and platelets (P=0.007) count along with elevated COVID-19 IgG antibody (P=0.002) and Erythrocyte Sedimentation Rate (ESR) (P<0.001).

    Conclusion

    RT-PCR is not necessary at admission; instead, some routine hematology examinations and serological tests can predict the prognosis of COVID- 19 disease.

    Introduction

    Flask-adherent Splenocytes (SACs) fulfill antigen-presenting cell requirements of acquired immune responses. This study was done to evaluate the efficacy of new immunotherapy against breast cancer made by SACs pulsed with the extract of heated 4T1 cells and Lactobacillus casei, as a probiotic.

    Materials and Methods

    Mammary carcinoma was induced by injection of 4T1 cell line in the flank of female Balb/c mice. The first SACs therapy was started on day 11 after tumor induction when all animals had developed a palpable tumor. SACs therapy was done twice at a 10-day interval.

    Results

    Mice with mammary tumors received SACs pulsed with combined heated 4T1 cells and L. casei determined a more desirable survival curve and a slower rate of tumor development compared to the other groups. At least 20% of the group receiving combined immunotherapy were alive by day 58. Those mice receiving SACs pulsed with the Lysate of heated tumor cells died by day 45.The maximum survival of other mice was up to 38 days after tumor induction. Moreover, SAC pulsed with combined agents significantly amplified the secretion of Interferon-γ (IFN-γ), and conversely reduced the secretion of Transforming growth factor-β (TGF-β) and Interleukin 4 (IL-4) in the splenocyte population compared to splenocytes from other groups. Combined immunotherapy increased the expression of p53 and caspase 3 genes and reduced the exertion of BCL2 more than other immunotherapy protocols.

    Conclusion

    Immunotherapy with SACs pulsed with heated 4T1 cells and L. casei promotes beneficial outcomes in the mouse model of breast cancer.

    Introduction

    Multiple Sclerosis (MS) is a chronic, autoimmune and progressive neurological disease that causes a wide range of cognitive deficits in patients by destroying the Central Nervous System (CNS). This study aims to examine the effect of Transcranial Direct Current Stimulation (tDCS) on working memory of patients with MS.

    Materials and Methods

    For this purpose, a quasi-experimental pre-t-est, post-test design with the control group was considered. In total, 32 patients with relapsing-remitting MS were selected using the convenience sampling method and randomly divided into experimental and control groups. The intervention consisted of 10 sessions of cranial electrical stimulation, during which the participants were divided into two groups receiving real and sham stimulation. N-Back test was employed to evaluate working memory.

    Results

    The data were analyzed using the independent t-test. The results revealed that working memory was improved in the experimental group compared to the control group (P<0.05).

    Conclusion

    It could be concluded that anodal tDCS over the right dorsolateral prefrontal cortex (R-DLPFC) appears to be a promising therapeutic tool for cognitive dysfunction among patients with MS.

    Introduction: Anxiety about COVID-19 is common and seems to be mostly due to the unknown and confusing nature of the virus. Given the effects of stress on maternal and fetal health and the lack of a similar study on this issue and the importance of the issue, so we decided to assess the degree of anxiety in COVID-19 in pregnant women. Materials and Methods: The present study is a cross-sectional study (descriptive-analytical). The statistical population of this study includes pregnant women referred to Kashani Hospital in Jiroft from March to August 2020. A total of 182 pregnant women referred to the hospital were interred in the study. Results: The mean age of pregnant women was 27.2±7.2 years. Among the demographic factors of pregnant women, only a significant relationship was seen between maternal age and anxiety caused by COVID-19. Also, the mean anxiety of psychological symptoms was significantly higher than the physical symptoms (P<0.001). Both factors indicated moderate anxiety. Conclusion: Given that there is currently limited information available to pregnant women with COVID-19 and its complications in pregnant mothers, it is necessary to pay more attention to corona prevention training programs and how to deal with stress and anxiety in pregnant women.

    Introduction

    Medication errors in patients’ medical records can influence the healthcare quality and cause risks for them. It is, therefore, crucial to apply appropriate procedures to reduce these errors. This study sought to develop a software for detecting medication errors through qualitative analysis of patients’ medical records.

    Materials and Methods

    The software was developed using object-oriented analysis and Java. The text was first pre-analyzed using a framework known as Stanford Core NLP. In the next stage, the text was turned into a semi-structured passage to be connected to Dr Onontology using Apache Jena framework. The name and dosage of available drugs were then extracted in the physician order forms and the patient progress notes. The areas of mismatch were identified through comparing the data obtained from these two forms.

    Results

    Software assessment was conducted in two stages. In the first stage, the capability of the software in proper recognition of medicine’s name was measured, as100 completed forms containing physician order forms with a total number of 1014 drugs were used for text mining and error detection. After running the analysis in the error detection software, 93% of the drugs were properly recognized. In the next stage, comparisons were made between the physician order forms and the patient progress notes to find possible mismatches. Out of 1000 recorded drugs in the analyzed forms, the software was able to properly detect mismatches in 91.8% of the cases. The medication data available in i2b2 were used for conducting the assessment.

    Conclusion

    Given that medical records are of paramount importance and their human analysis is a complicated and time-consuming process, deployment of a text miner with the capability of quality analysis could facilitate error detection efficiently and effectively.

    Introduction

    COVID-19 is known as a general health threat. General health can play a significant role in marital adjustment and satisfaction and thus the strength of the family foundation. The current study aimed to determine the correlation between families’ general health subcomponents and marital satisfaction during the COVID-19 pandemic in Khaf, Iran.

    Materials and Methods

    This descriptive-analytical study was conducted on 90 married people using the convenience sampling. The study instruments involved a demographics form, a general health questionnaire, and a marital satisfaction questionnaire. Data analyses were performed in SPSS statistical software ver. 22, using the Kolmogorov-Smirnov, Pearson correlation coefficient, multiple regression, independent t-test, one-way analysis of variance, and Tukey’s post hoc tests. The level of significance was set at p <.05.

    Results

    Among the general health subcomponents, the highest mean score belonged to depression (12.80 ± 4.65) and the lowest to social dysfunction (12.04 ± 4.24). The general health score was 49.70 ± 17.35, and the marital satisfaction mean score was 123.13 ± 34.02. Marital satisfaction was negatively and significantly associated with general health (r = -.71) as well as the subcomponents of somatic symptoms (r = -.64), anxiety (r = -.71), social dysfunction (r = -.66), and depression (-.067) (p <.001).

    Conclusion

    As COVID-19 depression and anxiety have the most significant impact on individuals’ general health and marital satisfaction, healthcare managers and policymakers are advised to consider solutions to these disorders in families. As such, they can contribute to spouses’ general health and marital satisfaction and thus strengthen the family foundation.

    Introduction

    It is clamied that α-pinene has properties against Multiple Sclerosis (MS) which is known as demyelination of the neurons. Given that, the aim of this study was to investigate the effect of α-pinene on Cuprizone-induced (CPZ) MS.

    Materials and Methods

    A total of forty C57BL/6 mice were allocated to 4 groups. Mice in group 1 (control) were treated with a normal diet. In group 2, CPZ-induced demyelination was done by chew palate containing .2% (w/w) CPZ for 5 weeks. In group 3, a normal diet was provided and mice were injected with 𝛼-pinene (1 mg/kg; i.p.) 3 times a week for 5 weeks. In group 4, mice were fed with the CPZ containing diet and injected with 𝛼-pinene (1 mg/kg; i.p.) three times a week for 5 weeks. At the end of the study, reflexive motor behavior and depressive- like behavior tests were performed. Additionally, serum anti-oxidant activity was determined.

    Results

    Results show that the CPZ had an adverse effect on reflexive motor behavior tests (P<.05) and co-administration of the CPZ+𝛼-pinene diminished the adverse effect of the CPZ on the reflexive motor behavior tests (P<.05). Moreover, CPZ significantly amplified immobility time (P<.05) and co-administration of the CPZ+𝛼-pinene reduced the adverse effect of the CPZ on depressive-like behavior tests (P<.05). CPZ significantly increased malondialdehyde (MDA) and decreased glutathione peroxidase (GPx), superoxide dismutase (SOD) and total antioxidant status (TAS) and also these effects were reversed by α-pinene (P<.05). The data indicate that co-administration of the CPZ+𝛼-pinene significantly improved the adverse effect of the CPZ on serum antioxidants (P<.05).

    Introduction

    The rapid outbreak of the new COVID-19 virus has become an international health challenge. Confronting the prevalence of this pathogenic virus requires, in the first step, health literacy and self-care on people’s part.

    Materials and Methods

    This descriptive cross-sectional study was carried out over three months. A total of 67 patients discharged from a COVID-19 ward were selected randomly. Data were collected using a validated researcher-made questionnaire on health literacy and self-care. The data were then analyzed using SPSS software version 16.

    Results

    Sixty-seven patients (mean age: 45.32 ± 9.39; age range: 29 - 87) were assessed. The majority were male (64.2%), married (79.1%), illiterate (44.8%), and homemaker or unemployed (37.3%). The overall mean score of health literacy and self-care was moderate. The results of the Pearson correlation test showed a significantly positive association between overall health literacy and its components as well as the total self-care and its components among the patients studied (p <.001).

    Conclusion

    Since self-care increases with health literacy among COVID-19 patients, it demands educational interventions in this area to improve health literacy.

    Introduction

    Ivermectin is a member of avermectins family which was discovered in 1967 in Japan. The contribution of this drug to animal and human health was so prominent that the researchers who found the drug were awarded a Noble prize in 2015. With the advent of COVID-19,lot of interest has shifted more towards ivermectin usage in treating the COVID-19 alone or in combination with other medicines as synergism. Since its introduction, ivermectin has helped to control many parasitic diseases of animals and humans. For many years after its discovery, ivermectin was considered to be only a parasitic agent, but as scientists continue to evaluate this drug, they discover more healing aspects.

    Materials and Methods

    For this review, we searched keywords from international databases including PubMed, Google Scholar, Science Direct and Scopus. The keywords were ivermectin, anticancer, anti-inflammation, antibacterial, antivirus, antiparasitic, and mechanism of action.

    Results

    Several studies have shown that ivermectin has a very powerful antiparasitic, antibacterial, and antiviral activity and it can also be used as an anticancer and anti-inflammatory agent.

    Conclusion

    The collected data showed that ivermectin can be used to control and prevent many pathogenic agents and it can also be repurposed for the treatment of COVID-19.

    Context:

    Targeted anti-cancer approaches bring about individual therapies to combat the complexity of most malignancies and enhance their chances of success. Currently, immunotherapy, which exploits the patient's immune system to fight the disease, has made a significant progress in the success rate of cancer treatment. T lymphocytes are one of the most powerful arms of the immune system against cancer cells; however, many tumor cells can escape by hiding their peptide antigens. Evidence Acquisition: CAR-T cells can detect tumor cells' HLA without any restrictions. Promising outcomes from CAR-T cell clinical trials have increased hope among cancer patients, making CAR-T cell a prospective treatment for most cancers. However, its unique toxicities and the possibility of recurrence have raised concerns among scientists.

    Results

    Therefore, in this review, in addition to the design of CAR-T cells, we intend to discuss the process of CAR-T cell therapy in the treatment of malignancies and explore its disadvantages, advantages, and prospects.

    Conclusion

    Despite extensive studies, it is not yet possible to confirm the role of CAR-T cells, but based on the experience of applying CAR-T cells, a definite treatment is feasible through immunotherapy and strengthening the immune system.

    Introduction

    Heterozygote β-thalassemia is called carrier or β-thalassemia trait (BTT). Carriers have no clinical symptoms but sometimes have a mild anemia. They can often be identified with MCV<80 fl, MCH<27 pg and HbA2> 3.5 %. However, these tests are not enough to diagnose some unexpected beta-globin mutations in premarital or prenatal screening.

    Case Presentation

    The mentioned case was one of the most common silent β-thalassemia mutations (promoter nt-101C>T).

    Conclusion

    It was the first report from Fars (Iran) and the second one from Iran. The case had normal hematologic indices and borderline hemoglobin A2 values that may be mistakenly interpreted as normal. The presented case showed that electrophoresis and PCR sequencing methods should be applied for screening thalassemia.

    With the advancements of science in recent years, novel therapeutic methods have been developed to treat microbial infections and improve medical performances. These novel methods are more accurate than the old ones; therefore, they are more effective. Technically, these methods may revolutionize science in the future. Some of these new therapies include phage therapy, precision medicine, next-generation sequencing, picotechnology, the use of recombinant proteins, microchips, and robotic surgery, each of which will in turn surprise the medical world. Although some of these treatments have been used in the past, researchers are now paying more attention to them because not only these newer methods are more accurate and efficient, but many of the older treatments, such as antibiotics, because of the increasing rate of the antibiotic resistance, are gradually losing its popularity. In this letter, some of the latest innovative medical therapies have been discussed; which you will hear more about soon.

    Introduction

     Nickel (Ni) is a toxic heavy metal that can damage the brain structure, especially the hippocampus which is an important complex brain structure with a major role in memory and learning. Recent studies showed that heavy metals can alter some brain functions and disrupt hemostasis in central nervous system (CNS). The role of chronic Ni administration on memory and leaning, survival of neurons in CA1 hippocampus and the level of oxidative stress marker in rats.

    Materials and Methods

     In total 24 rats (n=6) were allocated to four groups: Group (I): vehicle received intraperitoneal (IP) normal saline (0.9% NaCl), Group (II, III ,IV): received 0.25 mg/kg, 0.5 mg/kg and 1 mg/kg IP NiCl2 for eight weeks, respectively. During this timespan, the rats were examined in the Morris water maze and novel object recognition test to evaluate memory and learning. Finally, the hippocampus of the rats was extracted and survived neurons were evaluated by Nissl staining; oxidative stress was determined using malondialdehyde (MDA) level and catalase enzyme activity.

    Results

     Results showed that dose-dependent Ni administration decreased memory and leaning in behavioral studies and caused degenerative and morphological changes in neurons by elevating MDA and catalase enzyme activity as the most important oxidative stress markers.

    Conclusion

     Ni induces changes in the structure of hippocampal neurons and disrupts memory and learning function in hippocampus in adult rats by an increase in oxidative markers.

    Introduction

     there has been a growing number of publications focusing on the effect of beta-carbolines (e.g., harmane) on cognitive behaviors such as different stages of memory formation process. Moreover, several studies have stated that Alpha-lipoic acid (ALA) induces some molecular pathways effects including antioxidant effect and reduction of inflammation process. Thus, in the lines that follow, the question of whether ALA could alter memory consolidation deficit caused by harmane in the male NMRI mice will be addressed.

    Materials and Methods

     The data for this study were collected by step-down inhibitory avoidance task with one trial protocol for evaluation of memory consolidation. The ALA (35 mg/kg) was injected intraperitoneally immediately after training followed by subthreshold and effective doses of harmane (2.5, 5 and 10 mg/kg) with 15-minute interval period.

    Results

     The results show that post-training injection of the highest dose of harmane (10 mg/kg) lowers step-down latency, indicating the amnesia induced by harmane (P<.001). In addition, similar injection of subthreshold dose of ALA (35 mg/kg), 15 minutes before injection of subthreshold and effective doses of harmane, restores step-down latency caused by higher dose of harmane (P<.001) without its effect on the responses induced by subthreshold doses of harmane, indicating benefit effect of ALA on amnesia induced by harmane.

    Conclusion

     An implication of this study is the possibility that ALA can reverse the amnesia induced by harmane. Therefore, future studies on this topic such as molecular mechanisms are recommended.

    Introduction

    A body of pharmacological and non-pharmacological studies have been conducted with the purpose of attenuatingmorphine side effects such as anxiety and memory impairment. It seems that there is a close relationship between resveratrol and morphine according to molecular cell pathway. Thus, the aim of the present investigation was to evaluate the effect of resveratrol on anxiolytic-like behavior and emotional memory induced by morphine.

    Materials and Methods

    A basic experimental research has been designed for this study. The test-retest protocol of elevated plus-maze (EPM) apparatus was used. The male Wistar rat received subthreshold dose of resveratrol (52mg/kg), 15minutes before injection of saline (1ml/kg) or different doses of morphine (1025, 205and 5mg/kg) on the test day. Twenty-four hours after test day, the EPM’s parameters was also measured without drug injection. All drugs were injected intraperitonealy.

    Results

    The data indicated that higher dose of morphine (5mg/kg) elevated Open Arm Time (%OAT, P<.25) and Open Arm Enters (%OAE, P<.221) on the test day, and also %OAT (P<.25) and %OAE (P<.221) on the retest day, indicating decrease of anxiety and impairment of emotional memory, respectively. Moreover, subthreshold dose of resveratrol (52mg/kg) restored all parameters induced by higher doses of morphine in the test (P<.25for %OAT and P<.21for %OAE) and the retest day (P<.25for %OAT and P<.221for %OAE).

    Conclusion

    The principal findings of this research showed that resveratrol can alter morphine responses on anxiety and emotional memory process. It is also postulated that the resveratrol can decrease the morphine side effects in the people using it.

    Introduction

    Induction of ovulation results in changes in ovary including the tissue immune cells. Administration of progesterone following induction of ovulation may ameliorate some of these changes. The present study was conducted to examine the effect of this administration of progesterone on mast cell count and tissue histamine level in mice ovary at pre-implantation time.

    Materials and Methods

    An experimental study on 15 NMRI mice was carried out. The groups of study were control group, induction of ovulation group and a group for administration of progesterone after induction of ovulation. Mast cells count was through toluidine blue staining and tissue histamine level measure was through spectrophotometry. Analysis of variance (ANOVA) was used for data analysis.

    Results

    The mean of mast cell count was significantly different between the groups (P <.001). Pairwise comparisons showed that induction group had significantly higher mast cells in comparison with control group (P =.039), indicating the effect of ovulation induction on mast cell count. The count was higher in progesterone group in comparison with induction group (P =.020). Mean of histamine level was significantly different between the groups (P <.001). Induction group had significantly higher histamine level in comparison with control group (P <.001). However, histamine level was not significantly different between induction and histamine groups (P =.998).

    Conclusion

    Ovulation induction raises ovary mast cell population and histamine level. However, progesterone could notimprove this change. Further studies should be conducted to find further roles of mast cells and histamine in ovary

    Introduction

    The most prevalent malignancy during childhood is B-cell acute lymphoblastic leukemia (B-ALL). Many genetic variations are the causes of B-ALL. IKZF1 alterations are prevalent in childhood B-ALL cases, which are associated with a poor prognosis. This studyexamined seventy-two pediatric B-ALL patients for the frequency of IKZF1 alteration and types of IKZF1 deletions.

    Materials and Methods

    In this study, bone marrow aspirate specimens at the stage of diagnosis in pediatric B–ALL patients were used. The diagnosis of B-ALL was performed following cytomorphology, cytochemistry, and immunophenotyping based on the 2016 World Health Organization (WHO) guidelines. ALL translocations, including TCF3-PBX1 fusion, ETV6-RUNX1 fusion, BCR-ABL1 fusion, and KMT2A-AFF1 fusion, were performed on DNA specimens of all patients. IKZF1 status was checked with the SALSA MLPA P335 ALL-IKZF1 probemix Kit.

    Results

    The common-B ALL subtype was detected in 64/72 patients (88.9%). CD2 and CD13 aberrant expressions were found in 5/72 (6.9%) and 7/72 patients (9.7%), respectively. Molecular analysis for translocation revealed the frequency of ETV6-RUNX1 in 12/72 patients (16.7%) and BCR-ABL1 in 3/72 (4.2%). IKZF1 alterations were found in 13/72 patients (18%), of whom 10 (13.9%) had IKZF1 deletions. Three common types of IKZF1 deletions were found.

    Conclusion

    The frequency of IKZF1 deletion in this study is similar to the results already obtained in larger studies. The type of IKZF1 deletion related to poor outcomes has a higher frequency in this study. Because of the relatively high prevalence of IKZF1 deletion, its determination is important for better risk stratification and prognosis in pediatric B-ALL patients.

    Introduction

    Nowadays, acetylcholinesterase inhibitors are commonly used to improve the symptoms of Alzheimer's disease and central nervous system disorders. Marine algae’s contain compounds like alkaloids that have many biological activities. We aimed to investigate the inhibitory effects of some alkaloids with human acetylcholinesterase using molecular docking.

    Materials and Methods

    In this study, the interaction of 19 alkaloid compounds with human acetylcholinesterase (hAChE) was investigated using molecular docking. The initial structure of the compounds was optimized using mm2 method by Chem3D software; the compounds were evaluated as inhibitors on the gap of the active site of the enzyme by AutodackVina software, and the output results were analyzed by Discovery Studio software.

    Results

    The results showed that most of these compounds act as inhibitors with good binding energy (-7.7 to -9.8 kcal/mol). The best performance is related to the three compounds including Caulerpin, Martefragin A andN-Acetyl tyramine. Caulerpin was involved in hydrogen bonding with an affinity of -9.6 with the amino acids Histidine: 405, Arginine: 296, and Asparagine: 233. Martefragin A was involved in hydrogen bonding with an affinity of -9.6 with the amino acids Serine: 293, Phenylalanine: 295, and Arginine: 296, respectively. N-Acetyl tyramine was involved in hydrogen bonding with an affinity of -9.8 with the amino acids Asparagine: 186, Lysine: 53, and Glycine: 14.

    Conclusion

    The results of this study suggest that most of these alkaloid compounds can inhibit this enzyme by binding to the cleavage site of the active site of hAChE, and thus are suitable options for further studies to design new anticholinesterase drugs.

    Introduction

    Osteoarthritis is the most common chronic joint disease that affects both the elderly and the middle-aged people. This disease is the most common cause of limitation for the elderly and middle-aged people in daily activities significantly affecting the quality of their lives. The aim of this study was to evaluate the ultrasonographic findings in patients with knee osteoarthritis and its correlation with Western Ontario and McMaster Universities Osteoarthritis Indexes (WOMAC).

    Materials and Methods

    In this cross-sectional study, patients with knee osteoarthritis, who were referred to the rheumatology clinic of Imam Hospital from April 2020 to June 2021, were evaluated by radiographic and laboratory assessment. Laboratory tests included Rheumatoid Factor (RF), Anti-Cyclic Citrullinated Peptide (Anti-CCP), Antinuclear Antibodies (ANA), Erythrocyte Sedimentation Ratio (ESR) and C-Reactive Protein (CRP); patients with positive inflammatory and serological tests were excluded from the study. Then, patientswith osteoarthritis were visited by a radiologist for ultrasound findings and underwent ultrasound. In addition, the WOMAC questionnaire was administered at the same time.

    Results

    138 patients over 40 years old and 85.5% of whom being female were studied. The joint dryness score was significantly higher in patients with left synovial effusion (4.04 vs. 2.51; p = 0.001). In patients with right synovial hypertrophy, the mean overall score of WOMAC and its sub-branches was significantly higher (61.26 vs. 47.80; p = 0.001); also, mean joint dryness score in patients with left synovial hypertrophy is higher (4.15 vs. 3.17; p= 0.017).

    Conclusion

    The results of the present study showed that in terms of synovial inflammation, which includes hypertrophy and synovial effusion, there is a direct relationship with patients' WOMAC score, since ultrasound modality is non-invasive and available everywhere; moreover, the cheapness of this modality makes it possible to follow-up patients with osteoarthritis. This modalityis also reliable in assessing synovial changes, but more accuracy is needed in assessing cases such as osteophyte

    Introduction

    One of the most important determinants in health studies is health-related socio-economic status. The precise determination of health-related socio-economic classes is contingent upon updating the data and taking new cultural, social, and health factors. The objective of this study is to provide a practical method for determining the index and health-related socio-economic classes of the subjects under study.

    Materials and Methods

    A questionnaire containing68 items was developed as a tool to assess the socio-economic status index related to health. Data were collected from six hundred and four married individuals who were randomly recruited from the city of Tehran. To identify the prognostic variables of the model, linear regression method was used. Predicted values of the index were obtained using the model. Then, boundary lines were proposed to determine the five socio-economic classes using the K-means cluster method.

    Results

    Education, employment, internet access at home, use of supplementary health insurance, and time spent in virtual reality (cyberspace) were among the significant variables.

    Conclusion

    The socio-economic class determination table at the end of the manuscript presents a step-by-step method for calculating the index and determining the desired class with respect to gender.

    Introduction

    α-Amylases catalyze the starch hydrolysis reaction and are widely used in starch processing industries. Despite the high demand for the use of α-amylase in various industries, most α-amylases do not have the required functional characteristics such as proper activity, temperature and pH compatibility, as well as temperature stability. In this regard, ionic liquids are widely used today as co-solvents to improve enzymes' activity, stability, and selectivity.

    Materials and Methods

    Activity, optimum temperature, optimum pH, and thermal stability of B. subtilis α-amylase were investigated in the presence of 1-ethyl-3-methylimidazolium acetate. Structural changes in the presence of [EMIm][Ac] were examined using intrinsic fluorescence spectroscopy.

    Results

    The activity of α-amylase and Vm increased in the presence of 0.4 M of [EMIm][Ac] while Km decreased. The optimum temperature and pH did not change in the presence of [EMIm][Ac] compared to its absence. At 40 and 50 °C, the inactivation rate of α-amylase in the presence of both concentrations of 0.4 and 1 M of [EMIm][Ac] is the same as in its absence. However, the rate of inactivation at 60 and 70 °C is higher than that in the absence of [EMIm][Ac]. The results of intrinsic fluorescence spectroscopy confirmed the structural changes in the presence of [EMIm][AC].

    Conclusion

    [EMIm][Ac] can be used to increase the activity of B. subtilis α-amylase without affectingthe optimal temperature and pH parameters. Moreover, [EMIm][Ac] relatively improves the thermal stability of the α-amylase

    Introduction

    As a malignant proliferative disorder, multiple myeloma (MM) is classified as a cancer of the immune system. Generally, a complete blood count (CBC) is the first test for a patient with symptoms of MM. Through CBC, physicians can monitor abnormalities in the blood. To normalize malignancies in their blood, patients must first go through conventional chemotherapy. Afterward, if eligible, subjects would receive high-dose therapy and hematopoietic stem cell transplantation (HSCT). Primarily, patients would be subjected to autologous hematopoietic stem cell transplantation (auto-HSCT).

    Materials and Methods

    This retrospective cohort study consisted of 56 MM patients who were diagnosed between January 2010 and August 2016 and were followed up until February 2022. Thesurvival rate of MM patients was assessed based on CBC test at the time of diagnosis. The clinical conditions, i.e., Thrombocytopenia, Leukopenia, and Anemia, were extracted from the CBC test and were used as the desired prognostic factors in companion with age at diagnosis. Overall survival based on the mentioned factors was analyzed using the defective Marshall-Olkin gompertz cure model, which was programmed in R software version 4.0.3.

    Results

    The mean age at diagnosis was 52.76 (SD = 7.1). The probability of long-term survival for patients in this study was 46%, with five-year overall survival equaling 73.2%. Patients with thrombocytopenia had about 86% lower odds of long-term survival compared with patients with normal Platelet levels (Plt).

    Conclusion

    The present study indicates that deficiency in Plt count is a significant factor leading to poor survival of MM patients.

    Introduction

    Hypertension is growing as a running title public health problem. It is one of the most important risk factors for various diseases including cardiovascular disease. The study of laboratory markers and early detection of complications can play an effective role in controlling the disease.

    Materials and Methods

    The present study was a descriptive-analytical cross-sectional one that was performed from March 21, 2020, to March 19, 2021, on patients referred to Abadan and Khorramshahr educational hospitals with hypertension. Information on age, sex, and laboratory diagnostic factors of patients with hypertension admitted to HIS were received. Data were analyzed using STATA software.

    Results

    The study population involved 1505 patients with hypertension admitted to Abadan and Khorramshahr educational hospitals; there were 487 males (32%) and 1018 females (68%). The average age of the patients was 61 (SD: 12). The highest frequency of patients with hypertension was in the age group of 64-55 years with afrequency of 420 (27.9%). The results showed that the mean of creatinine was higher than normal. The mean of CK-MB and INR was slightly higher than normal. The two sexes were significantly different in terms of the means of CK-MB, AST, ALT, Cr, Na, MCHC, HCT, HB, and RBC. According to the unadjusted and multiple logistic regression analysis, each 1 unit increase in BUN and K+ was associated with an increase in the odds of abnormal creatinine. Each 1 unit increase in RBC, HB, HCT, MCH, and MCHC was associated with a decrease in the odds of abnormal creatinine, and each 1 unit increase in PT was associated with an increase in the odds of abnormal creatinine.

    Conclusion

    The results of the present study showed that some laboratory markers in patients with hypertension were above the normal range including renal, cardiac, and coagulation diagnostic factors and some of which depend on age and sex; thus, it is important to pay attention to these markers in controlling high blood pressure in these patients. Futurestudies are warranted to examine the issue further
