BACKGROUND MicroRNA-32 (miR-32) induces cell proliferation and metastasis in hepatocellular carcinoma (HCC), but the detailed mechanisms of miR-32 in regulating oncogenesis and development of HCC have not been clarified. The aim of this study was to investigate the effects of miR-32 on HCC and its clinical pathological significance, as well as to determine the functional connection between miR-32 and ADAMTS9 in HCC. MATERIAL AND METHODS Quantitative RT-PCR was used to assess the expression levels of miR-32 in HCC tissues, adjacent non-cancerous tissues, and liver cancer cell lines...

BACKGROUND Previous studies have shown that T cell immunoglobulin domain and mucin-3 (Tim-3) and interleukin-17 (IL-17) are implicated in the development of several autoimmune diseases. However, it is unclear whether these proteins contribute to the pathogenesis of systemic lupus erythematosus (SLE). The purpose of this study was to evaluate SLE patient serum Tim-3 and IL-17 levels, and to assess correlations between these proteins and major clinical parameters of SLE. MATERIAL AND METHODS Overall, 55 SLE patients and 55 healthy controls were recruited in a case-control study...

BACKGROUND Down syndrome (DS) is the most frequent genetic mental disability. Individuals with DS experience a variety of physical, motor, and functional challenges throughout the lifespan. However, the inter-relatedness between these domains is relatively unexplored in children with DS. This study aimed to determine which physical and motor characteristics contribute to functional performance in children and adolescents with DS. It also investigated the relationship between physical, motor, and functional domains...

BACKGROUND Diabetic cardiomyopathy (DCM) is a common but underestimated cause of heart failure in patients with diabetes. This study investigated the myocardial-protective effects of nicorandil (Nic) on rats with DCM. MATERIAL AND METHODS A total of forty-seven 180-220 g male Wistar rats were randomly divided into 4 groups: a control group (control, n=8), a DCM group (DCM, n=13), a nicorandil-pretreated DCM group (Nic1, n=13), and a nicorandil-treated DCM group (Nic2, n=13). A rat model of type 2 diabetes was induced by high-fat and high-sugar diet and intraperitoneal injection of streptozotocin (STZ)...

Stress affects cellular aging and inflammatory and chromosomal processes, including telomere length, thereby potentially compromising health and facilitating disease onset and progression. Stress-related diseases and strategies to manage stress usually require integrative or behavioral therapeutic approaches that also operate on cellular levels. Mind-body medicine (MBM) uses the interaction between the mind, body, behavior, and the environment to correct physical and psychological malfunctions, thus ameliorating disease states and improving health...

BACKGROUND Apoptosis plays a key role in the pathogenesis of Parkinson disease (PD). Active caspase-3, which is a proapoptotic factor, has been shown to reduce cardiac contractility, causing cardiac dysfunction in many pathological diseases. Reduced cardiac contractility and cardiac autonomic dysfunction have been reported in PD patients and PD mice treated with MPTP. The aim of this study was to show the impact of PD induction on the expression of the apoptotic mediators p53 and active caspase-3 in the heart...

BACKGROUND Low physical activity is considered to be a risk factor for type 2 diabetes mellitus (T2DM). One theory suggest that leptin resistance is involved in the pathophysiology of impaired glucose metabolism. In this study we aimed to assess the correlation of physical fitness scores (PFS) with serum total leptin (TL), serum leptin soluble receptor (LSR), and free leptin index (FLI) in a group of Saudi patients with T2DM. MATERIAL AND METHODS This cross-sectional study involved 115 subjects: 52 healthy control subjects and 63 patients with T2DM...

BACKGROUND Reducing stress in the workplace improves mental health. Teaching is of social importance, but it may receive inadequate recognition and rewards. The present study compared mental well-being and state anxiety in primary school teachers who practiced 15 days of yoga in a residential setting with those who continued their usual routine. MATERIAL AND METHODS We enrolled 236 primary school teachers to participate in the study. We assigned 118 primary school teachers (group mean ±S.D., age 41.5±6.0 years, 74 females) to the experimental group; they underwent 15 days of yoga training for 6 hours/day) in a residential yoga center...

Today's medical service delivery platforms provide everything from small urgent care 'offices' to large medical centers. Since 2007, an intermediate entity for care has been established, namely, the micro-hospital. Micro-hospitals are 24-hour, small inpatient facilities with an average of 2 to 10 beds, designed to provide a diversity of healthcare services consistent with community demands. In addition, they seek to combine a cost-effective healthcare vehicle with potential time-dependent triage/transfer capabilities to a nearby large medical center...

BACKGROUND New-onset atrial fibrillation (AF) is common after atrial flutter (AFL) ablation, but it was unclear whether AF ablation could reduce the incidence of AF in AFL patients without AF history. The present meta-analysis was conducted to evaluate the benefit of prophylactic AF ablation in reducing the occurrence of AF in typical AFL patients. MATERIAL AND METHODS We systematically searched PubMed, EMBASE, and the Cochrane Library from inception to December 2017 for randomized controlled trials (RCTs) that assessed the efficacy of AF ablation in reducing the occurrence of AF in AFL patients without AF...

The greatest challenge facing medicine today involves the so-called non-communicable diseases (NCDs). This is true regardless of whether one's location is considered high-income, middle-income, or low-income. Basic research at all "OMICs" system levels will be significant in uncovering causal links that create NCD vulnerabilities in mind, brain, body, and society. Therefore, meeting this 21st century challenge by improving NCD management and prevention around the world will rely on advancement in this type of basic research...

BACKGROUND Hepatocellular carcinoma (HCC) is the most common malignancy of the liver and recent studies have revealed that circular RNA (circRNA) plays an important role in the pathogenesis of HCC. Some circRNAs may act as a microRNA (miRNA) sponge to affect miRNA activities in the regulation of messenger RNA (mRNA) expression. However, the circRNA-miRNA-mRNA network in HCC remains largely unknown. MATERIAL AND METHODS The circRNA expression profiles (GSE94508 and GSE97332), miRNA and mRNA expression profile (GSE22058) were downloaded from Gene Expression Omnibus microarray data and then a circRNA-miRNA-mRNA regulatory network in HCC was constructed...

BACKGROUND Brain training games (BTG) are believed to play a major role in improving cognitive functions. The current study evaluated if BTG showed positive impact on attention and memory functions compared with baseline visit in healthy subjects. MATERIAL AND METHODS The study was carried out from October 2015 until April 2016 in the Department of Physiology, College of Medicine, King Saud University and in King Khalid University Hospital (KKUH), Riyadh, Saudi Arabia. We enrolled 51 normal healthy subjects to use a computerized cognitive training game (Lumosity) for exercises that target a range of cognitive functions, including attention, processing speed, visual memory, and executive functions for about 15 min per day, at least 7 days per week, for 3 weeks...

BACKGROUND Imatinib is actively transported into cells by the organic cation transporter (OCT1), encoded by SLC22A1. As a result, the expression of SLC22A1 is considered a prognostic marker for treatment with imatinib in patients with chronic myeloid leukemia (CML). Although limited, there is conflicting evidence indicating that imatinib may affect the expression of SLC22A1. However, thus far, no studies have investigated the effect of imatinib on SLC22A1 expression in an imatinib-sensitive cell line, which would mimic a typical clinical setting...
