Sudden death due to enterotoxemia among Arabian camels () and associated risk factors.

Background: Sudden death is defined as an unexpected death occurring with no observed antecedent clinical signs.

Aim: The current study was performed to notice the tangible causes of sudden death among 51 out of 340 she-camels on a private farm in the eastern region of El Khafgi, Saudi Arabia.

Methods: A retrospective cohort study design was conducted to investigate the sudden death of camels through microscopic examination of fecal matter to identify the gastrointestinal parasites, analysis of whole blood thin films to diagnose blood parasites, blood culturing to recognize bacterial infection as , and macroscopic postmortem examination to identify the gastrointestinal adult worm.

Impact of dietary Moringa oleifera leaf supplementation on gut morphometry, behaviour and physiological parameters in growing male rabbits.

Moringa oleifera (MO), a cultivated species of the Moringa, is known for its high concentration of essential nutrients that promote growth. To assess its impact on rabbits' gut morphometric, behavioural, and physiological parameters, a study was conducted using sixty growing male white New Zealand rabbits at 40 days old. The rabbits were divided into four groups and supplemented with dried MO leaves at varying levels (0%, 0.

Calcium-Based Binders in Concrete or Soil Stabilization: Challenges, Problems, and Calcined Clay as Partial Replacement to Produce Low-Carbon Cement.

Calcium-based binders, such as ordinary Portland cement (OPC) and lime (CaO), are the most common artificial cementitious materials used worldwide for concrete and soil improvement. However, using cement and lime has become one of the main concerns for engineers because they negatively affect the environment and economy, prompting research into alternative materials. The energy consumption involved in producing cementitious materials is high, and the subsequent CO emissions account for 8% of the total CO emissions.

Ameliorative effect of Spirulina and Saccharomyces cerevisiae against fipronil toxicity in Oreochromis niloticus.

The ameliorative effects of Spirulina and Saccharomyces cerevisiae (S. cerevisiae) against fipronil toxicity in Nile tilapia fish were investigated. Fipronil is a kind of pesticide that is widely used in agriculture, thus this trial was conducted to evaluate the effect of fipronil on growth related parameters (final body weight, feed intake, weight gain, feed conversion ratio, specific growth rate, and protein efficiency ratio), hematology related parameters (RBCs, WBCs, hemoglobin, packed cell volume, and deferential leukocytic count), biochemistry related parameters (alanine aminotransferase, aspartate aminotransferase, total protein, albumin, urea, and creatinine), histopathology of liver, intestine, gills, and spleen, and gene expression of antioxidants, stress, inflammatory, apoptotic, and related to junction proteins genes as SOD and GPx, COX II, TNF-α, Casp-3, and Claudin-3, respectively, in Nile tilapia (Oreochromis niloticus).

Impact of Dietary or Drinking Water sp. Supplementation and/or Heat Stress on Growth, Histopathology, and Bursal Gene Expression of Broilers.

This research was conducted to evaluate the impact of dietary or drinking water sp. supplementation and/or heat stress (HS) on the growth, serum biochemistry, tissue antioxidant, phagocytic assay, histopathology, and bursa gene expression of broilers. Day-old broiler chicks were allotted into six groups according to HS and/or with or without enzyme supplementation.

Prevalence and correlates of autism spectrum disorder in Qatar: a national study.

Background: Few epidemiological data on autism spectrum disorders (ASD) exist for Arabic countries. We conducted the first survey of ASD in Qatar, a population with high consanguinity level.

Methods: This cross-sectional survey was conducted from 2015 to 2018 in Qatar school-age children (N = 176,960) from national and immigrant families.

Increased culture recovery of Zygomycetes under physiologic temperature conditions.

Poor recovery of Zygomycetes hyphae from tissue specimens may result from failure of current culture methods to mimic physiologic conditions found in hyphae-laden infected tissue. We describe the use of an in vitro model simulating Zygomycetes growth under necrotic or hypoxic tissue conditions. We preconditioned hyphae of clinical Zygomycetes isolates in flasks under anaerobic conditions using Ana-Packs (Becton Dickinson Microbiology Systems, Sparks, MD) at 37 degrees C for 48 hours, thus simulating in vivo growth in an infracted hypoxic lesion, and compared the recovery of paired inocula at 37 degrees C and 25 degrees C.

Cholesterol import by Aspergillus fumigatus and its influence on antifungal potency of sterol biosynthesis inhibitors.

High mortality rates from invasive aspergillosis in immunocompromised patients are prompting research toward improved antifungal therapy and better understanding of fungal physiology. Herein we show that Aspergillus fumigatus, the major pathogen in aspergillosis, imports exogenous cholesterol under aerobic conditions and thus compromises the antifungal potency of sterol biosynthesis inhibitors. Adding serum to RPMI medium led to enhanced growth of A.
