Allergic diseases are one of the most prevalent diseases at present, it is imperative to understanding the pathophysiology and treatment strategies for allergic diseases. In this process, the binding of IgE and FcεRI on effector cells plays a critical role in triggering allergic reactions. However, the species specificity of the interaction between IgE and FcεRI has not been clearly explained. This review described the characteristics and Read More

Background: "Opuntia ficus-indica" (prickly pear) is the cactus member of the Cactaceae family as an important nutrient and food source. Objective: The purpose of this study was to characterize the phytochemical composition of hydroalcoholic extract of prickly pear seeds that cause therapeutic effects. Methods: Phytochemical screening based on simple tests and determination of secondary metabolites were perfor Read More

Background: Daptomycin is a popular anti-MRSA antibiotic, especially for surgical wound infections. The side-effects of Daptomycin dosage through intravenous administration have prompted the experimental use of topical Daptomycin. Also, combinatorial drug therapy involving noble metal nanoparticles and conventional antibiotics have proved beneficial in the past. The synergistic oligodynamic effect of Daptomycin with na Read More

Objective: This study aimed to observe the effects of dihydroartemisinin (DHA) on the proliferation, apoptosis, invasion, migration, and epithelial-mesenchymal transition (EMT) of the human gastric cancer cell line SGC7901 cultured in vitro. Methods: We applied varying concentrations of DHA to SGC7901 cells. Cell proliferation was measured using the cell counting kit-8 (CCK-8). Flow cytometry, Transwell invasion assay, and cel Read More

Background: In the course of neoplastic diseases, a reduction in SEMA3F expression is observed, which translates into an increase in the proliferative and proangiogenic potential of cells forming the tumor and the surrounding microenvironment. Objective: The aim of this study was to determine the changes in SEMA3F level in endometrial cancer depending on its grade. Methods: The study material consisted of tissue s Read More

Background: Recurrent pharyngotonsillitis due to Streptococcus pyogenes develops regardless of whether infecting strains are resistant or susceptible to first-line antimicrobials. Causation for recurrent infection is associated with the use of first-line antimicrobials that fail to penetrate deep tissue and host cell membranes, enabling intracellular S. pyogenes to survive throughout repeated rounds of antimicrobial therapy Read More

Background: The over use of current antibiotics and low discovery rate of the new ones are leading to rapid development of multidrug-resistant pathogens worldwide. Antimicrobial peptides have shown promising results against multidrug-resistant bacteria. Objective: To investigate the antimicrobial activity of a new ultrashort hexapeptide (OW). Methods: The OW hexapeptide was designed and tested against different st Read More

Background: To decipher EEG (Electroencephalography), intending to locate inter-ictal and ictal discharges for supporting the diagnoses of epilepsy and locating the seizure focus, is a critical task. The aim of this work was to find how the ensemble model distinguishes between two different sets of problems which are group 1: inter-ictal and ictal, group 2: controlled and inter-ictal using approximate entropy as a parameter. Metho Read More

Background: The development of antibiotic resistance amongst bacterial pathogens and a population explosion, e.g. in countries such as Indonesia, are two issues the world is facing today. These issues have stimulated interest in the development of new antimicrobial therapeutic agents and contraceptive strategies, such as novel spermicides. Bacteriocins, which are bacterially-derived antimicrobial peptides, may fulfill some Read More
