This article presents a novel dual-stimuli responsive nanogel prepared from human hair keratin and alginate through simple crosslinking method. Keratin offer the crosslinking structure and bio-responsive ability and alginate ameliorated properties of nanogels including particle size, stability and drug loading capacity. The resultant keratin-alginate nanogels (KSA-NGs) could function as promising vectors for doxorubicin hydrochloride (DOX) with a super-high drug-loading rate of 52.9% (w/w) and dual-stimuli responsive behavior to GSH and trypsin...

BACKGROUND: Health ATMs are terminals which are connected to a centrally located database storing patients' electronic healthcare records (EHR). These machines are capable of collecting information in a far superior fashion than humans and are also able to rectify obsolete data in a manner that humans are generally not inclined to. OBJECTIVES: The main goal of this study is to assess the importance of adopting health ATMs in the Kingdom of Saudi Arabia (KSA), which can improve the confidence of patients, reward health self-management, and achieve positive health outcomes through their easy-to-use applications that are secure and accessible through various devices...

In a straightforward and fast protocol, a mixture of 1,3-dimethylimidazolium fluoride ([DMIM]F) and 1-butylimidazolium tetrafluoroborate ([Hbim]BF₄) efficiently catalyzed the reaction of epoxides with ketene silyl acetals (KSA) to give various γ-lactones under metal-free conditions. Diverse kinds of the desired γ-lactones were directly prepared with high regioselectivities and yields in a simple one-pot procedure using [DMIM]F as Si-O bond activator and [Hbim]BF₄ as solvent and acidic ionic liquid catalyst...

Despite the great efforts by health authorities in Kingdom of Saudi Arabia (KSA), Cutaneous Leishmaniasis (CL) continues to be a major public health problem in the country. Many risk factors make KSA prone to outbreaks and epidemics; among these, rapid urbanization and the huge population movement are the most important. The disease is endemic in many parts of KSA, with the majority of cases concentrated in six regions, including Al-Qaseem, Riyadh, Al-Hassa, Aseer, Ha'il, and Al-Madinah. Leishmania major (L...

Regardless of the ban on the polychlorinated biphenyls (PCBs) decade ago, significant measures of PCBs are still transmitted from essential sources in cities and are all inclusive ecological contaminants around the world. In this study, the concentrations of PCBs in soil, the air-soil exchange of PCBs, and the soil-air partitioning coefficient (KSA) of PCBs were investigated in four noteworthy urban areas in Nepal. Overall, the concentrations of ∑30PCBs ranged from 10 to 59.4ng/g dry weight; dw (mean 12.2ng/g ±11...

The first liver transplant in Saudi Arabia was performed in 1991; however, it was not until 1994 that the first structured liver transplant program was launched. Until 1997, all liver transplants in the Kingdom of Saudi Arabia (KSA) were deceased donor liver transplantations. Programs performing liver transplants needed the authorization of the Saudi Center for Organ Transplantation (SCOT), which provides the essential support for organ procurement and allocation as well as regulatory support for organ transplantation in the country...

BACKGROUND: Transmission of dengue virus (DENV) through blood transfusion has been documented and hence screening for DENV during blood donation has been recently recommended by the American Association of Blood Banks and Centres of Disease Control and Prevention. DENV is endemic in the Western province of the Kingdom of Saudi Arabia (KSA) and serotypes 1, 2 and 3, but not 4, have been detected. However, little is known regarding the rates of DENV during blood donation in the kingdom...

MERS-CoV infection emerged in the Kingdom of Saudi Arabia (KSA) in 2012 and has spread to 26 countries. However, 80% of all cases have occurred in KSA. The largest outbreak outside KSA occurred in South Korea (SK) in 2015. In this report, we describe an epidemiological comparison of the two outbreaks. Data from 1299 cases in KSA (2012-2015) and 186 cases in SK (2015) were collected from publicly available resources, including FluTrackers, the World Health Organization (WHO) outbreak news and the Saudi MOH (MOH)...

In the Kingdom of Saudi Arabia (KSA) and Gulf region, a very small amount of municipal solid waste (MSW) is treated for compost production. The produced compost through traditional methods of compost piles and trenches does not coincide with the international standards of compost quality. Therefore, in this study, a continuous thermophilic composting (CTC) method is introduced as a novel and efficient technique for treating food waste into a quality compost in a short period of time. The quality of the compost was examined by degradation rates of organic matter (OM), changes in total carbon (TC), ash contents, pH, dynamics in ammonium nitrogen (NH4-N) and nitrate nitrogen (NO3-N), and nitrification index (NI)...

BACKGROUND: Approximately, 80% of the many cases of the Middle East respiratory syndrome coronavirus (MERS-CoV) confirmed worldwide were diagnosed in the Kingdom of Saudi Arabia (KSA). The risk of the disease spreading internationally is especially worrying given the role of KSA as the home of the most important Islamic pilgrimage sites. This means the need to assess Arab pilgrims' awareness of MERS-CoV is of paramount importance. MATERIALS AND METHODS: A cross-sectional study was carried out during Ramadan 2015 in the Holy Mosque in Makkah, Saudi Arabia...
