Different chemo-physical methods are used to synthesise titanium oxide nanoparticles (TiO2 NPs), which are often expensive, unfriendly to the environment, toxic, not biocompatible, with a small yield. To resolve these problems, the researchers use green procedures to synthesise TiO2 -NPs by plant extracts of Capsicum annum L. and Allium cepa (onion) and characterise using atomic force microscopy, scanning electron microscopy, transmission electronic microscopy, X-ray diffraction, ultraviolet (UV)-visible (Vis) spectra and Fourier transform infrared spectroscopy...

Background: Eating disorders (ED) are serious psychiatric disorders characterized by unhealthy eating habits. There is a limited number of studies on eating disorders among female university students in Arab countries. Therefore, the objective of this study was to examine the prevalence of disordered eating attitudes (EA) among female students at An-Najah National University, Palestine. Methods: A survey study on 2001 female students at An-Najah National University was carried out...

Lacosamide is one of the third-generation antiseizure drugs that block voltage-gated sodium channels by enhancing slow inactivation. The most common adverse effects of lacosamide include dizziness, headache, nausea, vomiting, diplopia, fatigue, and sedation. Less common side effects include memory impairment, weight gain, rash, and atrioventricular block. In this article, we describe a patient with Lennox-Gastaut syndrome who developed excessive laughing as a rare side effect of lacosamide with complete resolution after discontinuation of the medication...

Clay soil samples (0, 30, and 60 cm depths) were collected from two districts (Abu Al Khasib and Ad Dayr) in Basrah governorate in southern Iraq for gamma-ray spectroscopy. The activity concentrations for natural existing radionuclides in 18 soil samples were measured using high-purity germanium detector HPGe. From the obtained results of γ -ray spectroscopy, the 238 U activity concentrations were found to be ranging from 2.4 to 5.6 ppm with an average of 3.5 ppm in Abu Al Khasib and ranging from 2.1 to 4...

AIM: Novel quinazolinone and triazinoquinazolinone derivatives were designed and synthesized as apoptotic inducers. METHODOLOGY/RESULTS: Most of the synthesized compounds showed excellent antiproliferative activity against MCF-7 and HCT-116 cell lines, respectively. Compounds 7a, 8a, 8d, 14a and 14d were superior to doxorubicin as activators of caspases 3, 8 and 9 in HCT-116 cell line. The most potent caspase inducers, 8d and 14a showed cell cycle arrest mainly in G1 and S phase, respectively and increased the levels of p53, Bax and the Bax/Bcl-2 ratio compared with doxorubicin in HCT-116 cells with excellent selectivity against CCD-18Co human colon normal cell line...

Oral squamous cell carcinoma (OSCC) is still an unabated global killer with little advancement in its survival rate. DNA replication licensing proteins and Aurora kinase A are biomarkers that play important roles in genomic stability. The expression profile of minichromosomal maintenance protein 2 (MCM2), Ki67, geminin, and Aurora-A were linked to clinicopathological and outcome parameters, survival, and DNA content in 125 cases of OSCC. Oral fibroepithelial polyps (OFEP) were controls. The OSCC tumour cells were in a rapidly proliferating state, as assessed by the increased expression profile of MCM2, Ki67, geminin, and Aurora-A and of the geminin/Ki67 ratio, and the decrease of the MCM2/Ki67 ratio, in OSCC compared with OFEP (P < 0...

A sleep disorder is a medical disorder of the sleep pattern of a person that may be serious enough to interfere with normal physical, mental and emotional functioning. Disruptions in sleep can be caused by a variety of causes, from teeth grinding to night terrors. Sleep disorders are usually prevalent among adolescents and young adults, possibly due to factors related to life style, dietary habits, hormonal and emotional disturbances. Other factors that may precipitate sleep disorders include environmental, psychological and genetic factors...

The objective of this study was to evaluate whether or not the use of a prebiotic yeast cell wall (YCW) affects threonine requirements in starter broilers. Two hundred and forty 1-d-old Ross 308 broiler chickens were distributed among 2 Petersime battery brooder units (48 pens; 5 birds per pen). Different threonine to lysine ratios (0.60, 0.65, and 0.70 to 1.0) with 1.22% available lysine with and without YCW at 250 ppm was fed to the chickens in order to evaluate performance and intestinal morphology over a 21-d trial...

BACKGROUND Leiomyomas are benign neoplasms of the smooth muscle. When found in the pulmonary system, a rare occurrence, leiomyomas can result in hypertrophic osteoarthropathy, or significant clubbing, associated with proliferation of long bone periosteum. Bronchopulmonary fistulas, or communications between the bronchial tree and pleural space, are an uncommon postoperative complication of pneumonectomies. Even more infrequent is the presence of a bronchopulmonary fistula that is determined to be sterile. CASE REPORT The patient presented in the current case report is a 40-year-old previously healthy woman who presented with a 5-year history of chronic cough, right-sided chest discomfort, and dyspnea associated with back pain, and lower leg pain...

The aims of this study were to determine the following: first, are there educationally useful videos of parents of children with autism sharing their experiences? Second, do any of the data related to videos help in identifying useful videos? And third, what do posted comments tell us? YouTube was searched for videos of parents sharing their experiences. The following parameters were collected: title, creator, URL, duration, number of viewers, likes, dislikes, comments, days on YouTube, and country. Based on agreed-upon criteria, videos were divided independently into educationally useful and non-useful categories...

The last several years have seen a dramatic rise in the number of effective therapies that have been shown to improve survival outcomes for patients with advanced melanoma. Among these treatments are the immune checkpoint inhibitors, a new class of immunotherapy, that have demonstrated the ability to improve both response rates and survival outcomes. Pembrolizumab, an immune checkpoint inhibitor that blocks the negative regulatory PD-1 receptor on T-cell lymphocytes, has shown improved efficacy compared to standard therapies with an acceptable tolerability profile...

The infection rate of the hepatitis C virus (HCV) in Saudi Arabia is among the lowest in the world. However, it is likely that poor knowledge and awareness of HCV infection could minimize the effectiveness of prevention and control programs in the kingdom. Thus, the study objective was to estimate the prevalence of HCV infection, and to assess current knowledge about it, in the targeted population. Data on 5482 Saudi people attending primary healthcare centers in Jeddah City in 2014/2015 were analyzed in this cross-sectional study...

BACKGROUND: Complementary and alternative medicine (CAM) utilization is dramatically increasing among patients. As community pharmacies are a major provider of CAM products, community pharmacists need to have the sufficient knowledge and information to advice their patients, answer their inquiries and to be proactive in the healthcare process to ensure optimal therapy outputs and minimize both drug-drug and drug-herb interactions. Therefore, the main objective of this study was to assess the knowledge, beliefs, and practices of community pharmacists in Palestine about CAM...

AIM AND OBJECTIVES: To illustrate the Palestinian community's views, opinions and stances about the concept of do-not-resuscitate for terminally ill patients. BACKGROUND: Do-not-resuscitate orders are practised in many countries worldwide, but there is no consensus on their practice in the Middle East.

PURPOSE: Diabetic retinopathy (DR) is a serious cause of irreversible blindness and is the most common complication of diabetes. Annual fundus examination for diabetics aids in the prevention of blindness and allows intervening at a timely manner. As primary care physicians (PCP) are the main providers for diabetic care in Saudi Arabia, we aim to evaluate the current knowledge and awareness, and to assess practices among PCP regarding DR. METHODS: We conducted a cross-sectional study covering 46 randomly selected primary-care centers in Riyadh during October 2015...
