() is a plant with significant medicinal and nutritional value and contains various bioactive compounds, particularly in its leaves (MOL). This study sought to explore the impact of leaf polysaccharides (MOLPs) on lipopolysaccharide (LPS)-activated intestinal epithelial cells (IEC6) and to uncover the mechanisms involved. The cytotoxicity of MOLP on IEC6 cells was assessed using the Cell Counting Kit-8 (CCK-8) assay, which demonstrated a safe concentration range of 0-1280 µg/mL.

Various physiological functions and reaction cascades, as well as disease progression in the living systems, are controlled by the activity of specific proteolytic enzymes. We conducted the study to evaluate protease activity by assessing peptide fragments from either conserved or labeled red blood cells (RBCs) with aminofluorescein (AF) in the reaction media. RBCs were incubated in media containing trypsin.

Patient compliance following periodontal therapy is extremely important in predicting the prognosis of the disease and maintaining treatment outcomes. Therefore, this study aimed to investigate the perception of periodontitis patients about treatment outcomes. A cross-sectional study was conducted among periodontitis patients in a single dental center through a pre-validated questionnaire that was distributed to each participant in the waiting area of periodontal clinics by utilizing a convenience sampling technique.

Gastric schwannomas (GS) are rare mesenchymal tumors from Schwann cells in the gastrointestinal (GI) tract, representing 2-6% of such tumors. We report a 52-year-old woman who experienced abdominal pain, hematemesis, and melena, initially suspected of having a GI stromal tumor through ultrasound and computed tomography abdomen. Despite no active bleeding found during an upper endoscopy, she underwent a successful open subtotal gastrectomy, with histopathology confirming GS.

Aims: Micellar systems have the advantage of being easily prepared, cheap, and readily loadable with bioactive molecular cargo. However, their fundamental pitfall is poor stability, particularly under dilution conditions. We propose to use simple quaternary ammonium surfactants, namely, hexadecylamine (HDA) and hexadecylpyridinium (HDAP), together with tripolyphosphate (TPP) anion, to generate ionotropically stabilized micelles capable of drug delivery into cancer cells.

Undifferentiated carcinoma with osteoclast-like giant cells (UC-OGC) is a rare tumor type of pancreatic cancer. Paraneoplastic syndromes, an idiopathic inflammatory myositis characterized by various skin manifestations (such as dermatomyositis (DM)), cannot be attributed to the primary tumor itself. Here, we report an unusual case of UC-OGC presenting as a paraneoplastic syndrome, the first reported from Saudi Arabia and the Arabian Gulf states.

Appendicular diverticulitis (AD) is a rare entity characterized by the inflammation of the arising diverticulum of the appendix. It has been reported to carry a high risk of perioperative complications, such as bleeding and perforation. Furthermore, multiple articles have highlighted the importance of diagnosing AD early due to its strong association with malignancies.

Background: Sensorineural hearing loss is the most common type of permanent hearing impairment and results in postural control and motor deficits in children that may affect or delay all developmental indicators.

Objective: The purpose of the study was to objectively investigate the consequences of sensorineural hearing loss concerning postural control in pediatrics.

Methods: Forty students of both genders, ages ranging from 10 to 16 years, diagnosed with severe to profound sensorineural hearing loss, were selected from the Public School for the Deaf and Hard of Hearing in El-Minia district, Egypt.

Real-time safety prediction models are vital in proactive road safety management strategies. This study develops models to predict traffic conflicts at signalized intersections at the signal cycle level, using advanced Bayesian deep learning techniques and efficient LiDAR points. The modeling framework contains three phases, which are data preprocessing, base deep learning model development, and Bayesian deep learning model development.

The most common primary non-epithelial neoplasms of the gastrointestinal (GI) tract are gastrointestinal stromal tumors (GISTs). Ten percent (10%) of GISTs arise from the jejunum. Usually, patients complain of abdominal discomfort, but they may present with complications such as intestinal obstruction or bleeding.

A penetrating injury to the thoracic aorta is an extremely rare, life-threatening condition, with a high overall mortality rate. The incidence of a penetrating injury to the aortic arch is unknown because the majority of patients die before receiving adequate treatment due to excessive bleeding. Through a literature review, 23 cases of favorable outcomes were found.

Background: Chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are known risk factors for liver disease, cirrhosis and hepatocellular carcinoma (HCC). There is substantial global variation in HBV and HCV prevalence resulting in variations in cirrhosis and HCC. We previously reported high prevalence of HBV and HCV infections in Somali immigrants seen at an academic medical center in Minnesota.

Anatomic variations in the urogenital tract have generally been diagnosed through intravenous urography as a modality of choice. In recent years, computerized tomography (CT) urogram has replaced the traditional intravenous imaging of the genitourinary tract. Hematuria, tumoral mass, obstructive uropathy, and congenital collecting system abnormalities are indications for CT imaging.
