Background and Objectives: Friedreich ataxia (FA) causes progressive impairment of communication due to gradual deterioration of speech, associated with impaired hearing, socio-cognitive and language skills. There is an urgent need to investigate the impact of this multiparametric alteration on patients’ lives. Therefore, the COMunication and ATAXia measure (COMATAX) was developed and validated in French and German. Methods: I...

Intestinal ischemia reperfusion (II/R) is an abdominal critical case especially in neonates and during childhood affecting not only the intestinal tissue but also it could damage other remote organs including cardiac tissue even following surgical intervention. Immune homeostasis during II/R has a major role in controlling its progression. Thus, finding additive medical treatment besides the surgical one becomes an urgent need...

Climate change, including global warming, is associated with an increase in water temperature, which leads to increased water evaporation from water bodies, resulting in elevated salinity and decreased dissolved oxygen (DO 2 ) levels. This may deteriorate fish health and productivity, and threaten the sustainability of aquaculture. Hence, the current study was carried out to investigate the interactions between hypoxia and inc...

In the current investigation, the fishmeal (FM) protein was substituted by shrimp processing by-product (SPB) protein in feeds for Nile tilapia ( Oreochromis niloticus ) juveniles. Six isonitrogenous and isocaloric feeds were designed to substitute the FM protein with graded levels of SPB protein, i.e., 0% (SPB0), 10% (SPB10), 20% (SPB20), 30% (SPB30), 40% (SPB40) and 50% (SPB50). Nile tilapia juveniles (13—15 g) were allocate...

The current investigation assessed the beneficial impacts of dietary sodium chloride (NaCl) on the growth performance, oxidant/antioxidant, and immune responses of Nile tilapia ( Oreochromis niloticus ) and its adaptability to different salinity levels. After acclimating the fish to the laboratory conditions for 2 weeks, the acclimated fish (10.5 ± 0.16 g) were randomly distributed into 25 110-L rectangular glass tanks (15 fis...

Yeast, Saccharomyces cerevisiae , has been utilized as a probiotic in aqua-feeds to promote growth and alleviate the stress in aquatic animals. On the other hand, cadmium (Cd) toxicity causes serious retardation of growth and welfare status of aquatic animals. The present study was conducted to evaluate the protective role of dietary yeast in mitigating the waterborne Cd toxicity effects on the growth, haemato-biochemical, str...

Summary Phosphate (PO 4 ) is an important limiting nutrient in marine environments. Marine cyanobacteria scavenge PO 4 using the high‐affinity periplasmic phosphate binding protein PstS. The pstS gene has recently been identified in genomes of cyanobacterial viruses as well. Here, we analyse genes encoding transporters in genomes from viruses that infect eukaryotic phytoplankton. We identified inorganic PO 4 transporter‐encodi...

The present study provides quantitative estimates of soil, vegetation structure and species distribution in 144 stands along two transects in two extreme desert zones of western Egypt. This study had two aims: (1) to describe the floristic composition of the accidental type of vegetation growing in parts of the Western Desert of Egypt; and (2) to analyse the distribution of species in relation to certain environmental factors...
