Covid-19 is a widespread disease and its treatment is important. The present study was conducted with the aim of determining the effect of eight weeks of Pilates exercises on the lung function of women with a history of covid-19 disease.

20 inactive young women with a history of covid-19 disease in 1400 were randomly divided into two Pilates training groups (N=12, eight weeks, three sessions per week) and the control group (N=8). Respiratory indices (VC, FVC, FEV1, FEV1/FVC, MVV, and VO2max) were measured before and after the exercise program using a spirometer. Using SPSS26 software, to determine the difference between the groups using the ANCOVA test and to determine the difference between the pre-test times between the groups using the independent t-test and the pre-post-test times using the t-test A pair with a significant level (p<0.05) was used.

The average age of the subjects (control: 31.87±8.9, training: 39.66±7.26 years) was. Vital capacity (p=0.017), maximum voluntary deep breathing (MVV) (p=0.001), VO2max (p=0.041), in the post-test compared to the pre-test in the group Exercise had a significant increase. Also, VO2max in the training group increased significantly (p=0.001) and weight (p=0.001) and BMI (p=0.001) decreased significantly. Also; There was a significant decrease in weight and BMI variables in the post-test training group compared to the pre-test (p=0.001) and a significant increase in the control group (p=0.001).

The findings of the present study showed; Pilates exercise can be effective as a rehabilitation factor in the post-corona era for young women with a history of covid-19. However, more research in this field is necessary to reach definitive guidelines.

Enterococcus faecalis (E. faecalis) and E. faecium (E. faecium) are commensals of the gastrointestinal biota of humans and animals and are considered opportunistic pathogens. This study aimed to improve the knowledge about E. faecalis and E. faecium isolated from meat. To this end, 104 meat samples were collected from sheep, goats, cattle, and calves from Shahrekord local markets in Iran. Presumptive colonies of E. faecalis and E. faecium were isolated from the samples and subjected to identification tests. Antimicrobial susceptibility was determined using the Kirby-Bauer disc diffusion method, and polymerase chain reaction (PCR) was performed to detect some virulence genes. Furthermore, randomly amplified polymorphic DNA typing and repetitive element sequence-based PCR fingerprinting were used to show the clonal relatedness of the isolates. The results revealed that enterococci were present in 90 out of 104 samples. Specifically, E. faecalis and E. faecium were the commonly isolated species, with the predominance of E. faecalis, which exhibited high resistance to streptomycin (95%) but was susceptible to vancomycin (85.6%). Virulence genes detection showed that ccf and cpd genes were the most prevalent genes in both species. In addition, the molecular typing method indicated that the isolates belonged to separate subgroups. This study shows the contamination of meat products by potential pathogens and resistant enterococci. There is a need to implement regular surveillance to monitor the emergence of antimicrobial-resistant E. faecalis and E. faecium in food, particularly in meat production.

In this work, photostability, absorption and emission intensity of coated polycarbonate (PC) sheets with optical brightener (OB) as a wavelength converter material have been investigated. In addition, this coated sheet was used as a wall for microalgae culture flask, as a small scale photobioreactor, for studying the spectral conversion of UV-A radiation to blue light region and its effect on the biomas productivity of microalga Chlorella sp. For this purpose, the PC sheets coated by different concentrations of OB dissolved in thermoplastic acrylic resin were prepared and placed between the UV-A radiation source and the culture flasks. Results showed that the photostability increases under UV-A and solar radiation by applying two coating systems. Also, higher surface concentration causes an increase in emission intensity of coated sheet. Furthermore, compared with the uncoated sheets, the sheet coated with OB layer exhibited up to 70% higher biomass production of microalga Chlorella sp.

In this paper, the evolution of accretion disks in the post-Newtonian limit has been investigated. These disks are formed around gravitational compact objects such as black holes, neutron stars, or white dwarfs. Although most analytical researches have been conducted in this context in the framework of Newtonian dynamics and gravity, it is necessary to consider the effects of relativity on the structure of disks near the central body. To this end, by adding the post-Newtonian corrections to the hydrodynamic equations of the fluids, the equations for the time transformation of the accretion disks at the post-Newtonian limit were obtained; by using this equation, the surface density of the disk, which is dependent on radius and time, is got quasi- analytically. Finally, we compare the time evolution of the accretion disks in Newtonian and post-Newtonian gravity.

The purpose of this research is to investigate the effect of celebrities’ attractiveness on the effectiveness of advertisements, considering the factors influencing the attractiveness of the celebrities. this research is practical research and in case of its method it is a descriptive survey. Research’s data are collected using random sampling. In this research researchers’ questionnaire consisting of 17 questions is used and it’s contextually and structurally valid with a high Chronbach cooefficient of 0.91. In order to analyze data and testing the hypotheses of the research, structural equation modeling in LISREL is employed. Findings of research indicate that each of these variables, honesty and trustworthiness, familiarity, popularity, and credibility have a positive meaningful effect on celebrities’ attractiveness. In addition, there is a positive meaningful relationship between celebrities’ attractiveness and the effectiveness of addiction prevention advertisements. Using the celebrities in prevalentative advertising of addiction is effective.

Several clinical, laboratory and imaging modality was suggested for distinguishing infected from non-infected form of diabetic foot ulcer (DFU). This study was performed to compare erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and white blood cell (WBC) count as inflammatory marker in between infected and non-infected diabetic foot ulcer.

A process-research study was conducted on 90 individuals at the Baqiyatallah hospital (Tehran, Iran) between 2009 and 2010. The first group contained infected DFU according to the criteria of IDSA-IWGDF (n=30), second group contained non-infected DFU (n=30) and third group contained healthy individuals (n=30). Demographic, clinical and laboratory (ESR, CRP and WBC count) findings were compared between groups.

The mean and standard deviation (SD) of CRP in healthy, infected and non-infected diabetic foot groups were 1±1.4, 46.5±46.5 and 9.2±5.3 mg/dLit, respectively (p<0.001). The mean±SD of ESR (mm/h) in healthy, infected and non-infected diabetic foot groups were 6.4±6, 76.7±30.1 and 29.1±11.9, respectively (p=0.001) and also, the mean of WBC count in healthy, infected and non-infected diabetic foot groups were 6510±1149, 9846±3662 and 8073±2070 (in 109), respectively (p<0.001). ESR’s area in ROC curve (in diagnosis of infection) was statistically larger than other markers (AUC=0.967) and CRP (AUC=0.871) and WBC count (0.721) was at the next step. The best cut-off point for CRP, ESR and WBC count was 7.1 g/lit, 40.5 mm/h and 7700 per dlit, respectively.

Regarding to the results, although all of these three markers had significant value for predicting the infection, but ESR was introduced as the best independent predicting marker for distinguishing infection because of its higher sensitivity and specificity. Accompanying ESR with CRP or WBC count can increase the predicting value for discrimination of infection.

In this study, effect of spraying nickel sulfate and urea on reproductive growth, yield and some qualitative characteristics of strawberry fruit were investigated. Rooted daughter plants of strawberry, cv. Pajaro, were grown in 3 L pots in greenhouse of College of Agriculture, Shiraz University. The established plants were sprayed, at 4-5-leaf stage, with nickel sulfate at concentrations of 0, 150, 300 and 450 mg/L and urea at concentrations of 0 and 2 g/L. Some traits such as yield, weight of primary, secondary and tertiary fruits, length: diameter ratio, inflorescence number and number of flowers in each inflorescence, vitamin C, total soluble solids and total acid were recorded. Results showed that 300 mg/L nickel sulfate without urea increased significantly the yield, primary and secondary fruits’ weight and inflorescence number as compared to control. Also, the 300 mg/L nickel sulfate treatment with 2 g/L urea had the highest rate of total acid (0.75%). In general, spraying 300 mg/L nickel sulfate with 2 g/L urea is recommended for increasing the strawberry yield.
