OBJECTIVES Epidemiological and molecular studies have shown that sleep duration is associated with metabolic syndrome (MtS), a disease that is on the rise in the Kingdom of Saudi Arabia. We aim to investigate the association between sleep duration and selected cardiometabolic risk factors of MtS in a Saudi Arabian population. SETTING Secondary care was given to the participants. There were 2 ...

CactusWorld 2016 Vol. 34 (3) Aloe is a large genus of over 500 species (Carter et al, 2011) and even today that number continues to increase. Of these, a very small number of species, perhaps no more than 20, are unusual in having hairy flowers. These are concentrated in southern Arabia and the Horn of Africa. In respect of Saudi Arabia, for example, Collenette (1999) records 22 species of Aloe...

BACKGROUND Saudi Arabia annually reports a relatively higher proportion (28-32%) of extrapulmonary tuberculosis (EPTB) cases in comparison to other global regions. However, there were few studies conducted so far to determine the sociodemographic factors and clinical manifestations associated with EPTB at a nationwide level. METHODOLOGY A retrospective analysis on culture positive EPTB isolat...

BACKGROUND Gaudeamus is an enigmatic hystricognathous rodent that was, until recently, known solely from fragmentary material from early Oligocene sites in Egypt, Oman, and Libya. Gaudeamus' molars are similar to those of the extant cane rat Thryonomys, and multiple authorities have aligned Gaudeamus with Thryonomys to the exclusion of other living and extinct African hystricognaths; recent phy...

This paper explores the issues that influence online retailing in Saudi Arabia. Retailers in Saudi Arabia have been reserved in their adoption of electronically delivered aspects of their business. Despite the fact that Saudi Arabia has the largest and fastest growth of ICT marketplaces in the Arab region, e-commerce activities are not progressing at the same speed. Only very few Saudi companie...

The Arabian plate has been converging with Eurasia for 20-30 Ma, currently at 2-3 cm/year. Convergence is manifested differently along strike, with collision and tectonic escape in the west (Anatolia) and subduction of Arabia beneath Eurasia in the east (Iran). The reason for these differences may reflect the greater density of the Arabian lithosphere in the east relative to that in the west. F...

Introduction. Deuteronilus Mensae is a ~1000 km wide area along the highland/lowland dichotomy boundary in the northern mid-latitudes of Mars. In this region, features diagnostic of Martian 'fretted' terrain are observed, including lobate debris aprons, lineated valley fill, and concentric crater fill [1-5]. South of Deuteronilus Mensae are the rugged cratered highlands of Arabia Terra and nort...

The geological history of the Arabian Peninsula has played a crucial role in shaping current diversity and distribution patterns of many Arabian and African faunal elements. The gecko genus Hemidactylus is not an exception. In this study, we provide an insight into the phylogeny and systematics of 45 recognized species of the so-called Arid clade of the genus Hemidactylus from Arabia, the Horn ...
