It is one of the major causes of infertility in dairy cattle. Pathological ovarian cysts are classified into two groups including follicular and luteal cysts. Due to reduced fertility, increased calving interval, and the increase in the culling of cattle as a result of infertility, livestock industry has suffered from abundant financial losses. Hormonal and endocrine disorders are the causes of this disease that may occur through endocrine disrupting pesticides. This study aimed to investigate the relationship between plasma levels of diazinon and malathion with follicular cysts in dairy cattle. A case-control study was conducted on 30 cows. Diagnosis and selection of 15 cows (as the case group) with follicular cysts were done via rectal touch and ultrasonography, and plasma progesterone level was measured by a specialist. Control group consisted of 15 healthy cows that were homogenized with case group. Blood samples were taken from tail vein and were centrifuged, and the plasma was separated and stored at -80° C. Malathion and diazinon pesticides were measured by GC-MS (Gas Chromatography Mass) method in the plasma of the samples with 30ppb resolution. Independent t-test was used for comparing the means in healthy and case independent groups.

The photosensitizer based on hexyl ester of 5-aminolevulinic acid was used for the fluorescence diagnosis of bladder cancer. The study was conducted in 2015-2016 on the basis of the City Clinical Hospital No. 40 (Moscow, Russia). 53 patients were involved into study and were diagnosed as bladder cancer in T1N0M0 stage. Fluorescence diagnosis was carried out for 1 hour after the intravesical induction of 0.2% solution (50 mL or 100 mg) of Hexasens drug (FSUE \"SSC NIOPIK\", Russia). The results of the fluorescence diagnosis were compared with the results of the standard routine cystoscopy. The found results showed that the performance of fluorescent diagnostics (FD) led to improve diagnostic sensitivity as 13.2% compared to standard cystoscopy (from 86.8% to 100%); the diagnosis accuracy increased as 8.8% (from 91.2% to 100%) and a negative predictive value increased as 20.9% (from 79.1% to 100%). During the carrying out of fluorescence diagnosis, 8 patients (15.0%) out of 53 ones also revealed 14 fluorescing foci that not identified in white light, in which the tumorous process in them was confirmed during morphological study. The induction of Hexasens solution into a bladder and the carrying out of a fluorescent diagnosis was not accompanied by the development of any adverse reactions. Patients showed a subjective discomfort only during a prolonged exposure of the drug solution in a bladder (up to 2 hours). The developed diagnosis methods is recommended for the applying in advanced clinical diagnosis.","PeriodicalId":119340,"journal":{"name":"Journal of Biology and Today`s World","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127937400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Metals remediation by microbial activities associated with phosphorus metabolism is a promising method. The goals of this study were the removal of some heavy metals by isolated phosphate solubilizing rhizobacterium (PSR) and survey the effect of total secreted materials including extracellular phosphatase on this phenomenon. PSR strain was isolated by Pikovskaya (PVK) medium and identified by 16S rDNA sequencing. Its phosphatase enzyme was assayed by colorimetric method. Metal resistance of the isolate was measured by the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). The metal removal was detected by atomic absorption spectroscopy. The culture supernatant was analyzed for metal removal by secreted phosphatase enzyme with or without tri-calcium phosphate (TCP), as its substrate. The isolated rhizobacterium was identified as Acinetobacter calcoaceticus that produced acid phosphatase enzyme.

Here, 132 individuals were investigated (87 of them were patients with type 2 diabetes and 45 other were healthy, respectively). DNA was extracted from whole blood samples via a purification kit; then in order to the determination of quality, it was electrophoresised on agarose gels. Genotyping method was performed through high-resolution melt (HRM) reverse transcription polymerase chain reaction (RT-PCR). The visfatin level was determined based on enzyme-linked immunosorbent assay (ELISA) method. According to the achieved results, increasing the plasma levels of visfatin in diabetics patients (10.73 ± 5.38) compared to the control group (6.73 ± 1.88) and their changes based on the separation of genotypes also confirms that T allele is the probable risk factor (p-value < 0.05). In addition, the presence of the T allele is related to increasing triglyceride (TG) levels of blood. Therefore, adipose tissue burning and its reduction (along with the releasing of TG in the blood) decreased the source of visfatin, therefore increasing the TG in the presence of T allele (the development of diabetes) is associated with decreased plasma levels of visfatin. According to this study, evaluating plasma levels of visfatin and TG levels in blood is useful in prognosis of type 2 diabetes.","PeriodicalId":119340,"journal":{"name":"Journal of Biology and Today`s World","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133013506","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some physical and chemical features of soil, together with the amount of cadmium concentrated in soil and potatoes, were measured three times by Flame and Graphite Furnace Atomic Absorption Spectrometer and were analyzed through Mamdani Inference System by Toolbox of Matlab. The cadmium in potatoes and roadside farmlands was measured to be more than the standard amount; therefore, it illustrates high cadmium toxicity in the mentioned area.
