BACKGROUND The evolutionary history of Mesozoic terrestrial vertebrates from the Arabian Peninsula is virtually unknown. Despite vast exposures of rocky outcrops, only a handful of fossils have yet been described from the region. Here we report a multi-taxon dinosaur track assemblage near Madar village, 47 km north of Sana'a, Republic of Yemen. This represents the first dinosaur tracksite from ...

[1] Ambient aerosol samples were collected over the Arabian Sea during the month of March of 1997, aboard the German R/V Sonne, as part of the German Joint Global Ocean Flux Study (JGOFS) project. This is the third study in a series of analogous measurements taken over the Arabian Sea during different seasons of the monsoon. Dichotomous high-volume collector samples were analyzed for ferrous ir...

Data regarding genetic diversity of Arabian oryx(Oryx leucoryx)in Wadi Rum area of Jordan is not available so far. Therefore, the current study aimed to evaluate the genetic composition and structure of the Arabian oryx(Oryx leucoryx)herd in Wadi Rum area of Jordan using microsatellite marker analysis.Forty-nine Arabian oryx individuals were captured using a dart gun. Blood samples were obtaine...

Breeding records of 57 Arabian and 66 Thoroughbred mares were analysed to assess their reproductive performance under the subtropical conditions of Pakistan. The Arabian mares showed significantly higher conception rates (p<0.05) in second mated oestrus and foal heat mated oestrus compared to Thoroughbred mares. However, conception rates for first lifetime mated oestrus were similar in both bre...

This is a survey of the studies identified with the potential effect that the new changes of Kingdom of Saudi Arabia's vision for 2030 with a consideration on the Ministry of Education (MOE) in Saudi Arabia will influence the self-appraisal of Saudi understudies/students by their family’s interest or participation. A few studies indicate strong proof that the developments of the Kingdom of Saud...

Oxygen minimum zones (OMZ) are areas in the global ocean where oxygen concentrations drop to below one percent. Low oxygen concentrations allow alternative respiration with nitrate and nitrite as electron acceptor to become prevalent in these areas, making them main contributors to oceanic nitrogen loss. The contribution of anammox and denitrification to nitrogen loss seems to vary in different...

BACKGROUND The aim of this study was to determine the impact of metabolic syndrome (MetS) on lipid target achievements in the Arabian Gulf. METHODS The centralized pan-middle east survey on the undertreatment of hypercholesterolemia (CEPHEUS) included 4171 high and very high atherosclerotic cardiovascular disease (ASCVD) risk patients from six Arabian Gulf countries. Analyses were performed u...

STUDY DESIGN Retrospective study. PURPOSE To assess the prevalence of osteoporosis related spinal fractures among Saudi Arabian males. OVERVIEW OF LITERATURE Vertebral fractures are the most common complication of osteoporosis and is the first sign in both sexes and only 25 to 30% of radiographically observed vertebral deformities are recognized. METHODS We analyzed the chest radiographs ...

Archaeological survey undertaken in central Saudi Arabia has revealed 29 surface sites attributed to the Arabian Middle Paleolithic based on the presence of Levallois blank production methods. Technological analyses on cores retrieved from Al-Kharj 22 have revealed specific reduction modalities used to produce flakes with predetermined shapes. The identified modalities, which are anchored withi...
