The current study was aimed to investigate the effect of 1-OH-D3 on ileal digestibility of dietary calcium and phosphorus and turkey performance. A total of 225 one-day- old male bronze strain turkey with a mean body weight of 65 g were allocated to 3 treatments with 5 replications (each, 15 birds) for 8 weeks, under a completed randomized design. Diets were adjusted separately for two periods 1-4 and 5-8 weeks of age. The experimental treatments, for the first period were consisted: 1) control, containing D3 (4500 IU/kg) 2) 1-OH-D3 (0.14 gr/kg without D3) 3) 1-OH-D3 (0.07 gr/kg) + D3 (2250 IU/kg) and for the second period of experiment were consisted: 1) control, containing D3 (3500 IU/kg) 2) 1-OH-D3 (0.12 gr/kg) 3) 1-OH-D3 (0.06 gr/kg) + D3 (1750 IU/kg) in the diet. The results showed that no significant differences exist among treatments in turkeys’ body weight, feed intake and feed conversion ratio. However, the use of 1-OH-D3 in treatments 2 and 3 increased the ileal digestibility of calcium and phosphorus and the levels of calcium and phosphorus in plasma and bone, also decreased the activity of alkaline phosphatase in plasma, in compared to the control group (P<0.05). Our findings imply that inclusion 1-OH-D3 to the diet did not affect on growth performance in turkeys. However, it caused to increase absorption and accumulation of calcium and phosphorus in bone. In conclusion, 1-OH-D3 can be used to improve the quality of the turkey bone, alone or in combination with D3

Natural products from plants, animals, microbes and minerals have long been a traditional source for treating human diseases. Recent advances in analytical, spectroscopic, and high-throughput screening technology have greatly revived the discovery of natural drugs, including the contribution of marine products-based drugs. The marine environment is a unique resource that contains enormous biological diversity and may potentially lead to successful treatments. An increasing number of compounds from marine sources are entering clinical trials, and thus, the field's impact on the pharmaceutical industry is increasing. Marine organisms are excellent producers of natural chemicals with diverse structures and pharmacological activities. Most of the new products being produced from the sea are anti-tumor, anti-inflammatory and anti-infectious products. Invertebrates and seaweeds are diverse and at the same time rich sources of biologically active substances for the production of new drugs. Despite all the efforts made to isolate new drugs from the sea, due to the obstacles in the way of the mass production of these drugs, including the limitation of the reserves of marine organisms, the cultivation and propagation of these organisms and the isolation of medicinal substances from them, in the realm of experience and The test remains. However, according to the progress of science, marine medicines have a very bright perspective and will lead to the creation and expansion of effective treatment methods in the medical field in the near future.

Indiscriminate livestock grazing, rainfed agriculture in sloping lands, cutting of forest trees and other illogical uses of land have caused disturbance of the ecological balance of the environment, erosion of soils and reduction of their fertility in Savadkooh area. The purpose of this study is to determine the best way of exploitation in each of the parts of the land unit, in such a way as to obtain the maximum yield or income, to prevent the destruction of the land and to stop the current process of soil erosion as much as possible. separation of land resources and determination of their capabilities and suitability and talents, land use map of Savadkooh area were determined. Then, by using the FAO method, a detailed evaluation was done using the characteristics of the land and matching them with the tables of plant needs. By combining the results of the aptitude of land and its suitability for various agricultural activities, as well as plant needs and its relationship with the production potential index of suitable areas for agricultural activities in general and horticulture in particular, it is determined. Conclusion Studies of land potential show that the irremediable limitations and negative factors in horticulture are basically the limitation caused by the impossibility of irrigation in terms of water resource limitations and the limitation of the possibility of mechanization development in terms of the slope of garden lands.

Pain is defense mechanism and occurs when tissue is damaged. Pain receptors in the skin and tissues are free nerve endings. The pain in the tissues is due to the production of a substance called proaglandin, which is reduced by anti-inflammatory drugs. Eliphara plant is valuable in the food and herbal medicine industry and has a rare medicinal compound called aurantamide. Due to its anti-rheumatic anti-inflammatory effects in the treatment of diseases like arthritis, rheumatism and psoriasis, and by preventing the production of prostaglandins and increasing the production of glutathione, reducing the activity of aspartate aminotransferase, alanine aminotransferase enzyme and reducing the production of TNF-a factor, it reduces side effects. The aim of this study is to investigate the effect of Orantamide drug combination on prostaglandins with molecular docking. PubChem and PDB databases were used to investigate how the drug binds to the active site of the molecule, draw the chemical structure of the drug, energy optimization, binding studies and final analysis. The drug interaction with the receptor was done through different docks using Pyrex, Chimera and Viewer Lite software. The results showed that the desired compound was able to bind the active site of the enzyme and among the software, the best result was obtained from Pirex software. In fact, this compound had the highest level of negative binding energy (-7.5). Therefore, it was shown that the highest affinity for key amino acids is the active site of the enzyme and the site of interaction with the crystal molecule

This research was conducted in order to investigate the effect of changing the percentage of flour particles on the qualitative and rheological indicators of flour and bread production. The desired flour was prepared from wheat variety N87-20 and was divided into three parts by the size of particles by a sieve shaker. 6 treatments including the percentages of flour on a sieve of 180 microns, on a sieve of 125 microns and under a sieve of 125 microns, respectively: treatment 1 of the control sample (18%, 30%, 52%), treatment number 2 (10%, 40%, 50%) ), treatment number 3 (25%, 10%, 65%), treatment number 4 (20%, 20%, 60%), treatment number 5 (15%, 15%, 70%) and treatment number 6 (25%, 30 percent, 45 percent) was The results showed that the investigated treatments had no significant effect on the percentage of wet gluten, percentage of dry gluten, percentage of ash, percentage of protein, L* and a* of the produced flour and the sensory properties and porosity of the produced bread, but on the gluten index, Zeleny, Faling's number, The color index b* of flour and the color indices L*, a* and b* of bread production showed a significant effect and finally, considering that treatment 5 has the highest Zelani number, gluten index and sensory index scores, it is introduced as the best treatment.

Today, traditional and complementary medicine has a special place in the treating of many disorders and diseases. Valuable medicinal plants grow in Iran due to the special climate diversity. The barberry plant (Berberis vulgaris) is one of the most important and prominent plant species and has many therapeutic properties. Berberine, as the most important barberry alkaloid in the root, has a suitable concentration for extraction and utilization and introducing it as a natural substance with pharmacological properties is the aim of this research. The roots of the barberry plant were collected from Tehran city and ground after drying at ambient temperature and away from sunlight. Methanol was used to extract the berberine present in the root of this plant. After filtering, the methanolic extract was used to identify berberine using an HPLC device with a DAD detector. The resulting chromatogram shows the proper separation of barberry root extract and berberine peak peaks compared to the berberine standard, which was clearly separated and identified. The amount of berberine in barberry root was determined according to the calibration curve of 1.44%. Based on the obtained results and a review of the therapeutic and medicinal properties of native Iranian barberry, it is important to determine the amount of the effective substance in the context of its use in the prevention and treatment of various disorders and diseases.

Parsley snake (Echis carinatus) venom is a complex mixture of toxins. This venom contains metalloproteinases which convert prothrombin to meizothrombin. The prothrombin activator leads to the formation of small blood clots inside the blood vessels throughout the body. The case of a 24-year-old man living in the of Zabol city (Sistan and Baluchistan province) who was bitten by a snake on the right ankle (inner malleolus). This patient was brought to the emergency room at 24 o'clock with bleeding only from the decayed upper right wisdom tooth. patient immediately received 6 vials of anti-venom, but still the bleeding does not stop. Urgent CBCdiff, PT, PTT, INR tests were requested. The initial test was normal. 6 hours later, the test shows that the platelet level has decreased (from 200.000 to 120.000). Hydrocortisone ampoule 200μm, 6 more vials of anti-venom are received and finally the bleeding stopped and the platelets also increased (170.000). At the time of discharge, tetanus and tetabulin ampoules were injected. The snakebite treatment protocol should be done cautiously and carefully, because any negligence may lead to dangerous complications for the patient. Public education provided by health centers is essential to prevent snakebite.
