Identification at Biovar Level of Brucella Isolates Causing Abortion in Small Ruminants of Iran

To determine the most prevalent biovar responsible for brucellosis in sheep and goat populations of Iran, a cross-sectional study was carried out over 2 years in six provinces selected based on geography and disease prevalence. Specimens obtained from referred aborted sheep and goat fetuses were cultured on Brucella selective media for microbiological isolation. Brucellae were isolated from 265 fetuses and examined for biovar identification using standard microbiological methods. Results showed that 246 isolates (92.8%) were B. melitensis biovar 1, 18 isolates (6.8%) were B. melitensis biovar 2, and, interestingly, one isolate (0.4%) obtained from Mazandaran province was B. abortus biovar 3. In this study, B. melitensis biovar 3 was isolated in none of the selected provinces, and all isolates from 3 provinces (i.e., Chehar-mahal Bakhtiari, Markazi, and Ilam) were identified only as B. melitensis biovar 1. In conclusion, we found that B. melitensis biovar 1 remains the most prevalent cause of small ruminant brucellosis in various provinces of Iran

Atmospheric Water Generation (AWG): Performance Model and Economic Analysis

Part 2: Sustainability and Production ManagementInternational audienceUnited Nation’s 2018 Water Development Report estimated that more than 2 Billion people all around the world lack access to clean drinking water. In addition, many of our freshwater sources are declining. Therefore, exploring new methods of collecting clean drinking water is vital. Use of Atmospheric Water Generators (AWG) is one of these methods with the potential to contribute towards the salvation of our water problems. However, AWG’s performance is quite volatile in different environmental conditions and its economic feasibility is questionable. In this paper, an indicator model is developed to predict AWG’s performance in different conditions. This model is then used to examine the performance of AWG in Austin, Texas during a 4 year period. An economic analysis is carried out on the performance of the AWG system for a 4 year period from a single users’ perspective that exhibited an NPV value of $5964. This analysis showed that AWGs may indeed be financially feasible when utilized in Austin’s environment

Serum concentration of asprosin in new-onset type 2 diabetes

Background: Asprosin, a newly identified adipokine, is pathologically increased in individuals with insulin resistance. However, the available evidence on the association of asprosin and type 2 diabetes mellitus (T2DM) status is still scarce. Therefore, this study aimed to determine the relationship between serum concentrations of asprosin and T2DM status. Methods: This observational study was performed based on 194 adults (97 newly diagnosed T2DM and 97 healthy individuals). Anthropometric and biochemical variables were determined in all participants. Serum concentrations of asprosin were measured using enzyme-linked immunosorbent assay (ELISA). Results: In patients with T2DM, the serum concentrations of asprosin were significantly higher than the healthy controls (4.18 IQR: 4.4 vs. 3.5 IQR: 1.85, P < 0.001). The concentrations of asprosin were significantly correlated with body mass index (BMI) and fasting blood glucose (FBG) in healthy subjects and with BMI, FBG, hemoglobin A1c (HbA1c), homeostatic model assessment of insulin resistance (HOMA-IR), and quantitative insulin check index (QUICKI), triacylglycerol (TAG) and total cholesterol/high-density lipoprotein cholesterol (TC/HDL-C) ratio in the T2DM group. In fully adjusted model, the odds ratio (OR) of T2DM with serum concentrations of asprosin was approximately 1.547 (95% CI 1.293-1.850, P < 0.001) compared to the control group. Multiple stepwise regression analysis indicated that FBG and HOMA-IR were independently associated with asprosin in T2DM. Conclusion: Our findings indicated that serum concentrations of asprosin are increased in patients with T2DM. Also, asprosin is correlated with insulin resistance and TC/HDL-C ratio (atherosclerotic risk factor of cardiovascular diseases) in patients with T2DM. © 2020 The Author(s)

Detection and Identification of Toxoplasma gondii Type One Infection in Sheep Aborted Fetuses in Qazvin Province of Iran

Background: The aim of this study was to apply the nested-PCR and bioassay methods in detection and genotyping of Toxoplasma gondii infection in provided sheep aborted fetus samples from Qazvin Province of Iran. Methods: Eighteen sheep aborted fetal samples were studied by nested-PCR-RFLP, histopathologi&shy;cal observation and microbiological assay. Bioassay in mice was carried out by inoculating the brain samples intraperitoneally. Results: The results demonstrated the frequency of 66% infected sheep aborted fetal samples with T. gondii type one. Although we could not isolate any parasite from inoculated mice even after three pas&shy;sages, but it was confirmed histopathologically formation of cyst like bodies in prepared mice brain sections. Conclusion: The results of the performed nested-PCR and formation of brain cyst in inoculated mice exhibited that T. gondii type one infection might be considered as one of the major causative agents for abortion in ewes
