Most severe forms of intellectual disability (ID) have specific genetic causes. Numerous X chromosome gene defects and disease-causing copy-number variants have been linked to ID and related disorders, and recent studies have revealed that sporadic cases are often due to dominant de novo mutations with low recurrence risk. For autosomal recessive ID (ARID) the recurrence risk is high and, in po...

Brazil has the most populous and biodiverse semi-arid region in world (Brazilian Semi-arid - SAB). However, recent decades, clusters of desertification have emerged, a problem that could intensify from climate change. The objective this study was to elaborate on spatial distribution areas susceptible climatic SAB, considering future change scenarios. Understanding dynamic is essential for SAB's...

A llergic contact dermatitis to 2-octyl cyanoacrylate (Dermabond; Ethicon, Somerville, NJ) after surgical repair is an extremely rare condition with few reported cases. In recent years, contact dermatitis to Dermabond has been reported with increasing frequency. Cyanoacrylates are the most commonly used surgical adhesives and rely on their rapid polymerization to prevent sensitization from anti...

AHMAdi, M. R., H. R. GHAisARi: Heat stress and different timed-Ai methods influence on pregnancy rates of dairy cows. Vet. arhiv 77, 327-335, 2007. ABsTRACT The objective of this study was to evaluate three synchronization fix timed-AI protocols throughout the year on one commercial dairy farm in a semi-arid zone. Mean temperature-humidity indices (THI) were 77.5, 84.9, 70.8 and 58.8 in spring,...

Halophytes are plants which naturally survive in saline environment. They account for ∼1% of the total flora of the world. They include both dicots and monocots and are distributed mainly in arid, semi-arid inlands and saline wet lands along the tropical and sub-tropical coasts. Salinity tolerance in halophytes depends on a set of ecological and physiological characteristics that allow them to ...

Species composition, density, and temporal dynamics of zooplankton were studied in six reservoirs in a semi-arid region in tropical northeastern Brazil (Rio Grande do Norte state). All the reservoirs are highly eutrophic, with high contents of total nitrogen (minimum of 1200 µg.L(-1)) and total phosphorus (minimum of 10 µg.L(-1)), and extremely high algal biomass was registered (surpassing 20 µ...

AIM To monitor the effect of nutrition and pregnancy on oxidative status of animals under the arid condition of South Sinai. MATERIALS AND METHODS Blood samples were taken from two groups of animals: The first group retained in farm and fed on concentrate (high diet) and another group grazing natural forage (low diet). Each group was subdivided into pregnant and non-pregnant animals. Blood sa...

This paper evaluates the usefulness of the hyperspectral imager (HSI) onboard Chinese HJ-1-A small satellite in vegetation mapping. Fractional vegetation cover (FVC) is an important surface microclimate parameter for characterizing land surface vegetation cover as well as the most effective indicator for assessing desertification and crop growth condition. The HJ-1/HSI data were used to calcula...
