Integrative analysis of genetic, biochemical, and microbial factors in camel calf diarrheaNARA Subscribed
Diarrhea, though a clinical symptom, poses a major veterinary concern in camel calves due to high morbidity, mortality, growth retardation, and economic losses. This study investigated key bacterial enteropathogens, coding mutations, gene expression, and serum biochemical/antioxidant profiles in 35 healthy and 35 diarrheic camel calves. Fecal analysis using multiplex PCR identified Salmonella spp. , Clostridium perfringens, Pr...
Pre-weaning feeding is critical for calf growth, laying the foundation for future productivity and health. Nigella sativa seeds (NS) are rich in bioactive compounds with numerous beneficial effects on health and various pharmacological properties. This study aimed to investigate the supplementation of NS powder on performance, post-metabolic attributes, immunity, antioxidant capacity, and inflammatory responses in pre-weaning...
Enhanced Biochemical and Morphological Parameters in Eruca vesicaria by Applications of date-palm seed ExtractNARA Subscribed
The current global context stimulating agroecology and green agriculture need to explore for the novel sustainable and eco-conscious methods for safeguarding plants. The aim of this study is to exploit the rich contents of date palm seeds (DPS) as an appropriate organic elicitor to boost growth and plant secondary metabolism in Eruca vesicaria . The seeds of DPS were utilized in the extraction process using distilled water to...
Yeast feed additives present a natural approach for mitigating ruminal greenhouse gases (GHG) in an environmentally sustainable manner. This study aimed to isolate yeast strains from ruminal fluids capable of reducing GHG from Aflatoxin (AFB1) contaminated diets. Two isolates of Pichia manchuria (FFNLYFC1 and FFNLYFC2) were isolated and identified from the ruminal contents of dairy Zaraibi goats. An in vitro gas production ass...
Physiological and Molecular Effects of Calcium and Salicylic Acid on Fusarium graminearum-Infected Wheat SeedlingsNARA Subscribed
Fusarium graminearum is among the most virulent pathogens attacking wheat plants and significantly lowering its production globally. The present work aims to shed light on the interactions between two priming solutions, calcium (Ca) or salicylic acid (SA), and F. graminearum inoculation depending on the growth rate, physiological attributes, and molecular responses in wheat seedlings. In a pot experiment, F. graminearum -pre-i...
Potentials of mono- and multi-metal ion removal from water with cotton stalks and date palm stone residualsNARA Subscribed
In this work, cotton stalks ( Gossypium barbadense ) and date palm stones ( Phoenix dactylifera ) have been used as biosorbents to remove cadmium; Cd(II), lead; Pb(II), and zinc; Zn(II) from mono- and multi-solutions. Each biosorbent was characterized using SEM-EDX, and FT-IR. The findings showed that pH, dose, contact time, metal concentration, and particle size affect the treatment process. The adsorption pattern was Pb(II)...
The objectives of this research were to contrast the expression values of heat shock protein (HSP70) and interleukins 2, 6 and 12 (IL 2, IL 6 and IL 12) genes in summer and winter in two different locations in Egypt (Alexandria zone and Matrouh zone) to deduce changes in thermo-physiological traits and biochemical blood metabolites of Barki sheep. A total of 50 ewes (20 in Alexandria and 30 in Matrouh) were individually blood...
