α-Glucosidase, butyrylcholinesterase and acetylcholinesterase inhibitory activities of phenolic compounds from L. flowers: and studies.

Chemical investigation of L. flowers resulted in isolation of seven metabolites that were identified as; -Hydroxybenzoic acid (), hydroxy cinnamic acid (), kaempferol-6-C-glucoside (), astragalin (), cartormin (), kaempferol-3--rutinoside (), and kaempferol-3--sophoroside (). Virtual screening of the isolated compounds against human intestinal α-glucosidase, acetylcholinesterase, and butyrylcholinesterase was carried out.

Dynamic interplay between corticosteroid treatment and the role of SRC-1 gene dysregulation in the progression of WHO-Grade 4 Astrocytoma.

Background: Corticosteroid is commonly used before surgery to control cerebral oedema in brain tumours and is frequently continued throughout treatment. Its long-term effect of on the recurrence of WHO-Grade 4 astrocytoma remains controversial. The interaction between corticosteroid, SRC-1 gene and cytotoxic T-cells has never been investigated.

The Cancer Driver Genes IDH1 and IDH2 and CD204 in WHO-Grade 4 Astrocytoma: Crosstalk Between Cancer Metabolism and Tumour Associated Macrophage Recruitment in Tumour Microenvironment.

Purpose: IDH1 and IDH2 are hotspot mutations commonly identified in WHO-grade 4 astrocytomas. Their association with TAMs has never been investigated. We aim to explore the crosstalk between the IDH1/2 mutation metabolic effect and TAMs in tumour microenvironment and how this relationship affects the tumour recurrence.

Association Between CD204-Expressed Tumor-Associated Macrophages and -Promoter Methylation in the Microenvironment of Grade 4 Astrocytomas.

Background: Tumor-associated macrophages (TAMs) are principal immune cells in glioma microenvironment which support tumor growth and proliferation. Our aim in this study was to assess the relationship between CD204-expressed TAMs and O-methylguanine-DNA methyltransferase ()-promoter methylation in World Health Organization (WHO) grade 4 astrocytomas, and its impact on patient's clinical outcome.

Methods: The expression of CD204 TAMs was quantitively assessed on 45 samples of WHO grade 4 astrocytomas using immunohistochemistry.

Team-based learning versus interactive lecture in achieving learning outcomes and improving clinical reasoning skills: a randomized crossover study.

Background: This study aimed to investigate the impact of interactive lecture (IL) and team-based learning (TBL) on improving clinical reasoning skills (CRSs) and achieving learning outcomes (LO). Students' feedback was obtained about the strategies.

Methods: This study was carried out at the Faculty of Medicine in Rabigh, King Abdulaziz University, Jeddah, Saudi Arabia.

The Diagnostic Value of Pan-Trk Expression to Detect Neurotrophic Tyrosine Receptor Kinase (NTRK) Gene Fusion in CNS Tumours: A Study Using Next-Generation Sequencing Platform.

Neurotrophic tyrosine receptor kinase () fusion has been detected in rare types of CNS tumours, which can promote tumorigenesis. The efficacy of Trk inhibitor became a significant therapeutic interest. Our aim was to investigate whether Pan-Trk immunohistochemistry (IHC) is a reliable and efficient marker for detecting fusion in different brain tumours.

Undergraduate medical research in the Gulf Cooperation Council (GCC) countries: a descriptive study of the students' perspective.

Objective: There is a lack of research-oriented physicians in several Arab countries and especially in Gulf region countries. In this context, it is important to explore medical students' perceptions and motivations towards research. The aim of the present study was to investigate research attitude, practices, and motivations among medical students from GCC countries.

Unique features and risk factors of Helicobacter pylori infection at the main children's intermediate school in Rabigh, Saudi Arabia.

Background: This study was conducted to determine characters and risk factors of Helicobacter pylori infection and its relationship with recurrent abdominal pain and other gastrointestinal symptoms at the main children's intermediate school in Rabigh, Saudi Arabia.

Methods: A cross-sectional study was conducted at a boys' intermediate school. A questionnaire for the gastrointestinal (GI) symptoms and relevant personal and socioeconomic risk factors related to H.

Effect of sequential versus standard Helicobacter pylori eradication therapy on the associated iron deficiency anemia in children.

Objectives: Helicobacter pylori infection may be associated with low iron stores and iron deficiency anemia. Eradication of infection by the standard 10-day therapy (a proton pump inhibitor [PPI], clarithromycin and amoxicillin; each given orally, twice daily) is decreasing. The sequential 10-day therapy (a PPI and amoxicillin; each given orally twice daily for 5 days; followed by a PPI, clarithromycin and tinidazole; each given orally twice daily for another 5 days) may achieve higher eradication rates.

Treatment adherence and quality of life outcomes in patients with sickle cell disease.

Objective: To assess the health-related quality of life (HRQL) of patients with sickle cell disease (SCD) and to measure the impact of treatment adherence on disease complication, severity, crisis, and outcome.

Methods: This was a cross-sectional study on patients with SCD who attended the Hematology Clinic at King Abdulaziz University Hospital from January 2009 to December 2011. We measured the primary outcome of health-related quality of life (HRQL) using the World Health Organization quality of life assessment instrument (WHOQOL-BREF).

Therapeutic applications of mesenchymal stroma cells in pediatric diseases: current aspects and future perspectives.

Mesenchymal stem cells or stroma cells (MSCs) were recently proven to play various therapeutic roles when used in clinical trials to control various inflammatory, neoplastic and immunologic diseases in children. Clinical trials show some promising results, particularly in diseases where conventional therapy is still ineffective. However, experimental studies sometimes show conflicting results.
