Abstract: The clinical signs such as dyspnea, gasping, cyanosis and hyperemia are usually associated with the disease. However, the affected birds normally don't produce respiratory noise associated with other respiratory problems. Moreover, Aspergillosis primarily causes high morbidity and mortality especially in young chicks. Aspergilli can be isolated from environmental samples and are worldwide in distribution due to the spores of these fungal pathogens are resistant in nature and the birds as well as people who work with them, coming in contact with spores through contaminated feed or litter and may get affected after inhaling the spores. Poultry farm workers are at high risk of developing respiratory problems as they are exposed to high levels of dust containing Aspergillus spores during handling and processing of contaminated material.

Abstract: Background: The major cause of mortality among diabetic patients is cardiovascular diseases. The high plasma or serum levels of homocysteine and malondialdehyde are known as modifiable risk factors for CVDs. EPA has the antioxidant, antiinflammatory, antithrombogenic, and antiarteriosclerotic properties. Therefore, we investigated the effect of EPA supplementation on the serum levels of Hcy and MDA in the diabetic patients. Methods: This study was designed as a randomized, double-blind, and placebo-controlled clinical trial. Thirty six patients with type 2 diabetes were given written; informed consent, randomly were classified into 2 groups. They were supplemented with 2 g/day of the capsules of EPA or placebo. Blood sample for measurement of the serum levels of Hcy, MDA, and lipids, as well as FBS and HbA1c were given. Results: The patients supplemented with EPA showed a significant decrease in the serum levels of Hcy and MDA. There were no significant differences between the two groups regarding any demographic, clinical or biochemical data, total energy intake, and macronutrient intake at the baseline, and during the intervention, except for a significant increase of protein intake and the levels of HbA1c in the placebo group, and a significant increase of HDL-c, as well as a slight reduce of total cholesterol, LDL-c, TG and FBS in the supplement group. Conclusions: EPA is atheroprotective via decrease in the serum levels of Hcy and MDA, as well as change in the serum levels of lipids, FBS and HbA1c.

Abstract: The purpose of the present study is to investigate the impacts of eccentric exercises of hip adductor muscles on Range of Motion and performance of lower limbs among male Taekwondo players suffering from lower limb injuries. The population of the study includes the entire male Taekwondo players of Tehran during 2015. Among the population, a number of 30 individuals were selected as the sample of the study through purposive sampling method. Furthermore, the sample was divided into two 15 individuals groups namely as control and experimental groups. Prior to initiation of evaluations, subjects had signed the privacy policy papers for taking part in the experiment and next, their personal information was collected. Each person was individually provided with general debriefings regarding the manner of performance of tests. Conditions for participation in study also included having at least a two year experience of playing Taekwondo for three times a week and being aged between 16 to 20 years. Prior to execution of intervention program (hip adductor muscles strengthening program) subjects had been subjected to tests measuring Range of Motion of abduction and external rotation of hip using a Goniometer as well as kinetic performance of lower limbs through vertical jump test, one-foot single jump distance, one-foot triple jumps distance, stairway leap running time, sweep running time and one foot squatting test. Intervention included performance of eccentric exercises using a strap for strengthening hip adductor muscles for 8 weeks. 48 hours after execution of intervention program, the subjects have taken lower limbs strength and performance tests as they had taken their pre-test. Descriptive statistics have been used for describing and organizing data obtained from posttest and pretest. In term of inferential statistics, the Co-variance analysis was applied. In case of significance of average differences in Covariance test, the LSD post hoc test would be applied. It is noteworthy to mention that the entire statistical operations were performed using the SPSS software v.23. Findings of the study have shown that eight weeks of eccentric exercises of hip adductor muscles will lead to improvement of Range of Motion of hip abduction and external rotation as well as improvement of movement performance of lower limbs among male Taekwondo players suffering from groin strain. As a result, performing eccentric exercises is recommended for people suffering from groin injuries.

Abstract: Evaluating vegetation changes in every area is very important because if the monitoring of vegetation changes over time in each area be examined, changes of human pressure and environment would characterize. Thus, proper planning can be done to preserve the life of a region. Today for the vegetation evaluating the remote sensing and different indicators are used; NDVI is one of the most important indices in this field. In order to assess the vegetation of Eskandari watershed area in Isfahan province the Land sat TM sensor images were used. The vegetation of this area was prepared by NDVI index for the years 2000 and 2009. The results of this study showed that the vegetation in this area has increased. The changes of the urban areas are also notable. It is necessary that experts pay attention to the area in order to prevent damage to the vegetation due to the suitable climatic conditions that prevailed in the region in recent years.

Abstract: Desertification is the ecological and biological reduction of the earth, which may be either normal or abnormal. Desertification mainly affects arid and semi-arid regions and decreases the efficiency of the lands rapidly, so it is essential to recognize this phenomenon. In this study, the satellite images of Landsat 8 were used to investigate the desertification as the basis for studies. Based on the studies conducted on satellite images, Isfahan has grown about 260 square kilometers. During the same 10 year-period, the southeastern part of Yazd shows the most decrease in vegetation that is about 26 percent.

Abstract: Soil salinity is one of the causes of soil degradation in the world. The soil salinity occurs due to various reasons including saline formations, poor quality of accessible water resources, chemical pollution, inaccurate agriculture etc. Iran is also among the main countries faced with the soil salinity. The research has been done in Yazd’s area in order to examination of soil’s salinity (electricity transfer) with exploitation of geostatistical procedure. Geostatistical factors are used by Kriching. The 150 points have been done in order to determination of amount of electricity transfer in horizontal and vertical state by electromagnetic inductor device. Based on the obtained results, the marginal parts of the study area are more salty and with getting closer to the center the salinity decreases. Rocky heights are one of the reasons for the soil salinity decline in this part. Due to the increasing salinity zones, it is recommended to apply the preventive measures as soon as possible in this area..

Abstract: Objective: The goal of our work is to evaluate zinc status in cirrhotic patients that may indicate the pathophysiological as well as therapeutic role of zinc in liver cirrhosis. Background: Cirrhosis is the development of regenerative nodules in response to chronic liver injury, which leads to portal hypertension and end-stage liver disease. Zinc (Zn) is an important unique salt with various effects that depends on catalytic and structural function in anvarious number of enzymes and “Zn-finger” proteins. Patients with cirrhotic liver have low level of serum Zinc and their clinical condition improves with Zinc supplementation. Subjects and Methods: This study was carried on 53 patients with cirrhosis of the liver and 10 normal volunteers as control. They include 33males and 20 females, their ages ranged from 33 to 70 years. Patients taken from inpatients and outpatient gastroenterology clinic of Menoufia University Hospital. Blood samples were obtained and for all these samples complete blood assay (CBC), Complete liver parameters (AST, ALT, Prothrombin time (PT), GGT, Alkphosphatase, and total bilirubin), estimation of serum zinc levels, albumin level in serum and abdominal ultrasound were done. Results: Our study shows that in cirrhotic patients, there is low level of serum Zinc and shows also that Child C patients had lowest serum level of Zinc than Child B or A. Our study also shows low level of Hb, platelets, GGT and albumin in patients rather than control also there are increased level of RBCs, ALT, AST, PT, INR and bilirubin in patients rather than control. Conclusion: There is low zinc level in serum of patients with liver cirrhosis. As cirrhosis increases, level of serum Zinc decreases. Hb, platelets, GGT and albumin are low while RBCs, AST, ALT, PT, INR and bilirubin are higher in patients with liver cirrhosis than control.

Abstract: Exposure to doses of ionizing radiation is associated with physiopathological and histopathological changes. These changes differ in their severity according to the radiosensitivity and responses of individual organs and tissue. The aim of this study was to elucidate the possible therapeutic effect of ethanolic olive leaves extract (OLE) or bone marrow mesenchymal stem cells (BM-MSCs) on kidney of irradiated adult male rats using biochemical parameters, histopathology and quantitative histochemistry. Material and methods- 60 adult male albino rats (Sprague dawely strain) were used in this study. They were divided into 5 groups (C group: Untreated control rats; R group: rats exposed to a single dose of gamma-radiation (3 Gy); OLE group: rats were treated with olive leaves extract (15 mg /kg body weight/day for 30 days); R+OLE group: rats of this group were treated with olive extract 15 mg /kg body weight/day for 30 days after irradiation; R+MSCs group: rats of this group were irradiated with 3Gy then injected with bone marrow mesenchymal stem cells (BMSCs) 1106 cells/500L suspension through caudal vein about 6h post radiation exposure. The experimental rats were sacrificed on the 7th and 30th day post irradiation, except (R+MSCs) group were sacrificed only on the 30th day post exposed to radiation. Results- Rats exposed to gamma radiation showed many biochemical changes which included a significant increase in serum urea, creatinine and kidney MDA level while, kidney GSH level showed a significant decrease. Many histopathological lesions were observed in the kidney tissue, congested, lobulated and atrophied glomeruli with wide Bowman spaces, most tubules were dilated, cellular detachment, pyknotic nuclei, intratubular leukocytic infiltration, edema and thickening of atrial wall. In addition, irradiated group showed a significant increase in collagen and amyloids, while a significant decrease in PAS+ve materials, total protein and total DNA content was detected. Conclusion- From the biochemical, histopathological and histochemical studies, ethanolic olive leaves extract and mesenchymal stem cells ameliorated the induced kidney tissue damage of the irradiated group. MSCs proved to have more powerful therapeutic effect than that observed by OLE.

Abstract: Different environmental conditions are one of the most important issues related to the growing of plants. In the meantime, water stress is considered one of the greatest problems facing the plant productions in arid and semi-arid areas including Iran. This experimental study was conducted to evaluate the effect of irrigation interval and chemical fertilizer on yield and uptake percent of elements of alfalfa in a farm located in Khash in the year 1395. The experiment was conducted as split plots in completely randomized blocks design with three replications. The main plot was assigned to irrigation interval with four levels I1 (six days), I2 (seven days), I3 (ten days) and I4 (twelve days) and subsidiary plot was allocated to the amount of chemical fertilizer with four levels of F1 (control-zero), F2 (N100 -P70-K40), F3 (N150-P100-K70) and F4 (N200-P150-K100). The results showed that increasing the irrigation intervals decreased morphological characteristics such as wet and dry weight of root and aerial parts of plant; that this reduction can be caused by insufficient water available to the roots, stomata closure and reducing photosynthesis which ultimately reduces the functions of the mentioned traits.

This research in Ardekan region to assess soil salinity (electrical conductivity) took place by using geostatistical methods (Kriging and Inverse Distance Weighted methods). Numbers 150 points were collected to determine the amount of electrical conductivity by machine of electromagnetic inductor. Based on the results obtained of the southern part of study area has more salinity and towards the north of the region are closer from salinity decreases. Based on the results method of inverse distance weighting is more accurate compared to method kriging method.

Abstract: The prophylactic potentials of five Nigerian higher fungi – Pleurotus tuber-regium, Pleurotus pulmonarius, Termitomyces robustus, Fomes lignosus, Lentinus subnudus and their combination in equal proportion (mixture extract) were investigated. The ethanolic fungi extracts were tested on sets of albino rats (Rattus norvegicus) infected with selected bacteria (Escherichia coli, Staphylococcus aureus, Salmonela typhi, Pseudomonas aeruginosa, Streptococcus feacalis and Bacillus subtilis. Extracts were orally administered at 1.0ml concentration against 0.1ml/cfu microbial suspension intraperitoneally. Survival rates of the experimental rats were monitored. Mixture of these extracts exhibited significant level of prophylactic effect against all the bacteria in the host organisms.
