Fluctuations of testosterone and cortisol levels in male dromedary camels in response to behavioral and management situations.

Background: Biostimulation is a management practice that improves the reproductive parameters, potentiates the desire, and improves the reproductive efficiency during the short breeding season in camels.

Aim: This study aims to investigate the concurrent changes in hormonal profiles in response to management and behavioral situations on camel farms in the Eastern region of Saudi Arabia.

Methods: A total of 10 male and 50 female camels were used in this study.

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey.

Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice.

Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure.

An Investigation on the Effects of Partial Replacement of Rapeseed Cake in Ayrshire Dairy Heifers' Diets with By-Product Source of Animal Protein on Body Weight Dynamics, Nutrient Balancing, and Blood Biochemical Markers.

Recently, the secondary use of by-products of the processing industry resulting from the production of poultry meat, which can be included in animal diets, has become a popular topic in the feed industry. For studying the effects of partial replacement of rapeseed cake (RC) with the by-product source of animal protein concentrate Agro-Matic (PCAM) on growth dynamics, nutrient absorption and nitrogen balance, as well as blood biochemical parameters during the growing period, a total of 48 Russian Ayrshire dairy heifers were selected for this experiment and they were divided into three experimental groups (16 in each group, including the control group). The heifers of the control group were fed the basal diet which contained rapeseed cake (30%), while the second (RC + PCAM) and third groups (PCAM + RC) were fed the basal diet after replacing a part of the rapeseed cake with 2.

Unexpected Negative Performance of PdRhNi Electrocatalysts toward Ethanol Oxidation Reaction.

Direct ethanol fuel cells (DEFCs) need newly designed novel affordable catalysts for commercialization. Additionally, unlike bimetallic systems, trimetallic catalytic systems are not extensively investigated in terms of their catalytic potential toward redox reactions in fuel cells. Furthermore, the Rh potential to break the ethanol rigid C-C bond at low applied potentials, and therefore enhance the DEFC efficiency and CO yield, is controversial amongst researchers.

Crocin lessens desipramine-induced phospholipidosis biomarker levels via targeting oxidative stress- related PI3K/Akt/mTOR signaling pathways in the rat liver.

Unlabelled: Background and aim Crocin is a pharmacologically active chemical found in the spice saffron from Crocus sativus L. It possesses antioxidant and anti-radical properties that can minimize the hepatic phospholipidosis triggered using the tricyclic antidepressant desipramine. The aim of this study was to examine the effect of crocin on desipramine-induced hepatic phospholipidosis targeting the oxidative stress-related PI3K/Akt/mTOR signaling pathways.

Infrared Camera Geometric Calibration: A Review and a Precise Thermal Radiation Checkerboard Target.

Different infrared (IR) planar geometric calibration targets have been developed over the years that exploit a well-established and flexible optical camera geometric calibration procedure following the pinhole approximation. This geometric calibration is typically neglected in IR cameras, due to the relatively low resolution of thermal images and the complex IR targets needed for the geometric calibration in comparison to the optical targets. In this study, a thorough literature review of numerous IR camera geometric calibration targets, along with their respective outcomes, were summarized and leveraged to deliver a practical checkerboard target for less experienced end users, while offering the lowest reprojection errors.

Carbon-Supported Trimetallic Catalysts (PdAuNi/C) for Borohydride Oxidation Reaction.

The synthesis of palladium-based trimetallic catalysts via a facile and scalable synthesis procedure was shown to yield highly promising materials for borohydride-based fuel cells, which are attractive for use in compact environments. This, thereby, provides a route to more environmentally friendly energy storage and generation systems. Carbon-supported trimetallic catalysts were herein prepared by three different routes: using a NaBH-ethylene glycol complex (PdAuNi/C), a NaBH-2-propanol complex (PdAuNi/C), and a three-step route (PdAuNi/C).

Polymorphisms of the PRLR Gene and Their Association with Milk Production Traits in Egyptian Buffaloes.

Prolactin (PRL) and its receptor (PRLR) were considered as potential genetic markers for milk production and quality traits in cattle. However, little information is available regarding genetic diversity and association studies with milk traits in Egyptian water buffaloes. Therefore, the present study was conducted to search for mutations in and determine their associations with milk performance in these animals.

Investigation of total immunoglobulin G concentration, heavy chain antibody levels, and neutrophil to lymphocyte ratio in female camels and their newborn calves.

Camels belong to a group of animals, where the structure of placenta does not allow intrauterine transfer of maternal immunoglobulins to the fetus and maternal immunity is exclusively transferred by colostrum to the newborn calf. There are few studies on the passive transfer of maternal immunity in the dromedary camel. This study determined total immunoglobulin G concentration, heavy chain antibody (HCAbs) levels, and neutrophils to lymphocytes ratio (NLR) in female camels and their newborn calves.

Ginger and Its Derivatives as Promising Alternatives to Antibiotics in Poultry Feed.

Poultry enterprises have sustained rapid development through the last three decennaries. For which reason, higher utilization of antibacterial, either as therapeutic or growth promoting agents, has been accepted. Owing to the concern of developing bacterial resistance among populations towards antibiotic generations, accumulation of antibacterial remaining's in chicken products and elevating shopper request for outcomes without antibacterial remaining's, looking for unconventional solutions that could exchange antibacterial without influencing productiveness or product characters.

Ivy sign in mildly symptomatic β-thalassemia intermedia, with development of moyamoya disease.

Cerebrovascular occlusive disease with secondary proliferative angiogenesis can be idiopathic as a standalone disease state, known as moyamoya disease, or it may develop secondary to different disease entities, such as chronic hemoglobinopathies, in which case it is known as moyamoya syndrome. Although moyamoya syndrome has been well described with sickle cell anemia, its association with other hemoglobinopathies is rarely reported. We describe a 16-year-old girl with β-thalassemia intermedia who presented with recurrent headaches and focal seizures non-responsive to medical treatment.

Mathematical modeling of the biomechanics of the lamina cribrosa under elevated intraocular pressures.

Comprehensive understanding of the biomechanical performance of the lamina cribrosa (LC) and the optic nerve head is central to understanding the role of elevated intraocular pressures (IOP) in chronic open angle glaucoma. In this paper, six closed-from mathematical models based on different idealizations of the LC are developed and compared. This approach is used to create further understanding of the biomechanical behavior by identifying the LC features and properties that have a significant effect on its performance under elevated IOP.
