The objective of this study was to investigate the content of essential elements in medicinal plants in the Kingdom of Saudi Arabia (KSA). Five different medical plants (mahareeb (Cymbopogon schoenanthus) , sheeh (Artemisia vulgaris) , harjal (Cynanchum argel delile) , nabipoot (Equisetum arvense) , and cafmariam (Vitex agnus-castus) ) were collected from Madina city in the KSA. Five elements Fe, Mn, Zn, Cu, and Se were determined by using inductively coupled plasma mass spectrometry (ICP-MS). Fe levels were the highest and Se levels were the lowest in all plants...

Vitamin D deficiency is common in the Kingdom of Saudi Arabia (KSA). Therefore, it is significant to recognize which biochemical markers modulate serum 25 hydroxyvitamin D (25(OH)D) in response to vitamin D supplementation in such a population. Our aim was to study the correlation of insulin-like growth factor (IGF) and insulin growth factor binding protein (IGFBP) with serum 25(OH)D in response to vitamin D supplementation in a Saudi population. A total of 199 (89 males/110 females) vitamin D deficient subjects (25(OH)D level <50 nmol/L), aged 40...

Aim: Smokeless tobacco (ST) use is a significant health risk and cause of disease. Most studies conducted in the Kingdom of Saudi Arabia (KSA) focused on cigarette smoking. Therefore, the objective was to study the epidemiologic pattern and types of oral ST usage in northern and western Saudi Arabia. Materials and methods: A total of 428 volunteers living in three cities (Hail, Mecca, and Tabuk) were investigated. All of the study subjects were currently ST users of one type or more, including toombak, shammah, pan masala (PM), Afdhal, Nashooq, and others...

Rafik Harrath, Faisel M Abu Duhier
The Middle East Respiratory Syndrome Coronavirus (MERS-CoV) is a novel Coronavirus which was responsible of the first case of human acute respiratory syndrome in the Kingdom of Saudi Arabia (KSA), 2012. Dromedary camels are considered as potential reservoirs for the virus and seem to be the only animal host which may transmit the infection to human. Further studies are required to better understand the animal sources of zoonotic transmission route and the risks of this infection. A primary sero-prevalence study of MERS-CoV preexisting neutralizing antibodies in Dromedary camel serum was conducted in Tabuk, western north region of KSA, in order to assess the seopositivity of these animals and to explain their possible role in the transmission of the infection to Human...

Indoor settled dust particles are considered as an important source of human exposure to chemicals such as organophosphate flame retardants (PFRs). In recent decades the Kingdom of Saudi Arabia (KSA) has experienced tremendous growth in population, as a result the number of masjids has also increased significantly to provide sufficient space for the public to offer prayers. The hospitality industry in KSA is also expanding to cater for the ever-increasing number of pilgrims visiting the two holy cities of the kingdom...

Numerous studies have reported that pollutant reduction rates by ferrous iron (Fe2+ ) are substantially enhanced in the presence of an iron (oxyhydr)oxide mineral. Developing a thermodynamic framework to explain this phenomenon has been historically difficult due to challenges in quantifying reduction potential ( EH ) values for oxide-bound Fe2+ species. Recently, our group demonstrated that EH values for hematite- and goethite-bound Fe2+ can be accurately calculated using Gibbs free energy of formation values...

Background: Interstitial lung diseases are diseases that need histology diagnosis or obtaining a lung biopsy to establish the diagnosis. Surgical biopsies are performed usually using the thoracoscopy technique under general anesthesia (GA) although this procedure is still associated with morbidity rate. The aim of this study is to determine the effectiveness and safety of regional anesthesia (RA) compared with GA in thoracoscopic lung biopsy procedures done on patients with idiopathic pulmonary fibrosis (IPF)...

This study evaluated the bioenergy potential of Wolffia arrhiza via pyrolysis. The biomass was collected from the pond receiving city wastewater. Oven dried powdered biomass was exposed to thermal degradation at three heating rates (10, 30 and 50° C min-1 ) using Thermogravimetry-Differential Scanning Calorimetry analyzer in an inert environment. Data obtained were subjected to the isoconversional models of Kissenger-Akahira-Sunose (KSA) and Flynn-Wall-Ozawa (FWO) to elucidate the reaction chemistry. Kinetic parameters including, Ea (136-172 kJmol-1 ) and Gibb's free energy (171 kJmol-1 ) showed the remarkable bioenergy potential of the biomass...

Fish bone, a by-product of fishery processing, is composed of protein, calcium, and other minerals. The objective of this study was to investigate the effects of a bioactive peptide isolated from the bone of the marine fish, Johnius belengerii, on the osteoblastic differentiation of MC3T3-E1 pre-osteoblasts. Post consecutive purification by liquid chromatography, a potent osteogenic peptide, composed of 3 amino acids, Lys-Ser-Ala (KSA, MW: 304.17 Da), was identified. The purified peptide promoted cell proliferation, alkaline phosphatase activity, mineral deposition, and expression levels of phenotypic markers of osteoblastic differentiation in MC3T3-E1 pre-osteoblast...

Eichhornia crassipes is an aquatic plant well known for its role in soil reclamation due to the containment of valuable nutrients. Moreover, its biomass is an abundant and low-cost biological resource. While pyrolysis of a biomass offers one of the cleanest methods to harness the bioenergy stored in the biomass. The present study was focused on evaluating the bioenergy potential of Eichhornia crassipes via pyrolysis. Biomass of E. crassipes was collected from a municipal wastewater pond. Oven dried powdered biomass of E...

In this study, we demonstrated that the choice of precursor has a strong effect on the reduction of nitrate (NO3 - ) using zero-valent copper (Cu0 ) synthesized by sodium borohydride (NaBH4 ). Different precursors: CuSO4 , CuO, Cu2 O, Cu powder, and Cu mesh were used to reduce NO3 - at 677 mg-N/L under the reducing conditions of NaBH4 . Compared with the prehydrolyzed samples, those prepared without prehydrolysis exhibited lower reduction rates, longer times and higher concentrations of nitrite (NO2 - ) intermediate...

BACKGROUND: Catheter related blood stream infections (CRBSI) are the leading cause of morbidity in HD patients. The majority of these infections relate to haemodialysis catheters. There is a paucity of local data on microbial agents responsible for CRBSI in our region. This prompted our study. METHODS: This Prospective observatory survey was conducted in Department of Nephrology, King Fahd Hospital, Hofuf KSA from Nov 2014 to Jan 2017 (26 months). It was performed on dialysis patients with HD catheters who developed features of CRBSI...
