{"title":"Morphological, Histological Changes and Acetyl Cholinesterase Activity in Chick Embryos After Exposure to Abamectin Insecticide","authors":"Banan Taha, R. Mohammed","doi":"10.38094/jlbsr20248","DOIUrl":"https://doi.org/10.38094/jlbsr20248","url":null,"abstract":"Abamectin is a bio-insecticide, derived from the soil bacteria Streptomyces avermitilis. This insecticide is used in public health and agriculture to protect crops. Major adverse impacts of Abamectin are neurological symptoms acting on the peripheral nervous system. The aim of the current study is to reveal the toxic effects of Abamectin on chick embryo Ross 308 including morphological and histological changes and acetyl cholinesterase activity. 120 fresh fertilized eggs were divided into 6 groups; two of them were used as control. After 2 days of incubation, the eggs were injected with 100 µL of Abamectin solution (diluted at concentrations 360, 540, 900 and 1800 ppm) into the yolk sac. The Results showed that the mortality increased significantly in chicks treated with Abamectin, but had a lower weight in comparison to the control groups. Treated chicks started hatching at day 22 but were physically weak with drooping limbs, paralysis and then died after 24 hours of hatching. Some chicks did not normally hatch and needed assistance. They characterized by limb defects, failure retraction of yolk sac with bleeding. Histological examination of the liver showed hepatic cell degeneration, congestion in the central vein, infiltration of inflammatory cells and hepatocytes necrosis. Furthermore, the Acetyl cholinesterase enzyme analysis showed a significant decrease in the enzyme activity which leads to inhibition the activity of the body systems. It is concluded that low and high concentration of Abamectin has adverse impacts on chick embryo by changing some of morphological, histological characteristics and acetyl cholinesterase activity.","PeriodicalId":300980,"journal":{"name":"Journal of Life and Bio Sciences Research","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123567373","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}

This study is aimed to identify Candida spp. isolated from urine specimens by using traditional techniques, germ tube, growth on corn meal agar medium and chromogenic medium then determine the ability of isolates to producing biofilm by tube method (TM) and congo red agar method (CRA). In our study urine specimens were obtained from 174 diabetic females in the period of six months at the Al-Wafa Specialized Center for Diabetes and Endocrinology, Mosul city, Iraq. Out of the total 174 specimens, yeast species were isolated from 56 (32.2 %) specimens. Out of the 56 isolates, 50 isolates were positive for Candida spp., especially C. glabrata which appeared maximum in 30 isolates (60 %) and followed by C. albicans 18 isolates (36%) and C. krusei 2 isolates (4 %). In the TM method for biofilm detection, C. albicans showed 16 isolates (88.9%) positive for biofilm formation followed by 29 isolates (96.7%) of C. glabrata. Furthermore, in the CRA method, all isolates (100%) of C. albicans were negative followed by 27 isolates (90%) of C. glabrata, whereas only 3 isolates (10%) of C. glabrata were positive. We can conclude that TM is the best conventional method and is sensitive to detect biofilm-forming yeast when compared with the CRA method.","PeriodicalId":300980,"journal":{"name":"Journal of Life and Bio Sciences Research","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133284683","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}

Asprosin associated with insulin resistance and promotes hepatic glucose production. Previous studies showed that serum asprosin was raised in the general population with polycystic ovary syndrome (PCOS). However, there were studies supporting the opposite. Also, there were studies that showed the highest levels of asprosin was due to insulin resistance, as well as in type 2 diabetes patients. PCOS is one of the metabolic disorders related to insulin resistance. Therefore, the current study aims to evaluate the levels of asprosin in the blood serum of women with PCOS compared to the healthy women who resident in Duhok in the Kurdistan Region of Iraq. A cross-sectional study was conducted from 20th of June, 2020 to 11th of January, 2021 at Obstetrics and Gynecology Hospital and Mazi medical clinics. Serum asprosin level was determined in 75 women with PCOS (18-44 years) and 96 healthy women. SPSS software was utilized for analyzing the study data. The (means ± SD) of demographic parameters (body mass index (BMI) and waist circumference (WC)) in women with PCOS were significantly highest in comparison to healthy women. The biochemical parameters (serum asprosin, fasting blood sugar (FBS), fasting insulin (FI), total cholesterol (TC), and triglyceride (TG)) in women with PCOS also were remarkably higher compared to healthy women with the exception of high-density lipoprotein- cholesterol (HDL-C). The current data show that serum asprosin variance significantly between WC, BMI, FBS, FI, TC, TG and HDL-C. The study confirms that serum asprosin in women with PCOS was higher than in the healthy women. In addition in women with PCOS it was found that serum asprosin was positively correlated with BMI, WC, FBS, FI, HOMA-IR, TC and TG (P<0.05). Except, HDL-C was negatively correlated with serum asprosin (P<0.01).","PeriodicalId":300980,"journal":{"name":"Journal of Life and Bio Sciences Research","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128599661","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}

Sterilized seeds of Capsicum annuum were inoculated with the Agrobacterium rhizogenes inoculum. The samples were then transferred to the surface of solidified MS medium. Hairy roots were developed at the inoculation sites and were enucleated 1.0-1.5 cm length and placed in 9.0 cm Petri-dishes containing 15 ml of agar solidified MS medium. Agropine test was performed according to the standard method. The inoculated seedlings showed a good response 90%. Transformed hairy roots were established at the injection sites within 10 days and these roots were easily grown on agar-solidified MS medium. The results are confirmed that these roots were transformed roots it in terms of positive agropine detection. The current study concluded that the biological interaction between Agrobacterium rhizogenes strain R1601 and Capsicum anuum L. seedlings, was successful.
