Three types of serotypically atypical Shigella flexneri strains were isolated from 2007 to 2008 in patients at the Korea National Institute of Health (NIH). These strains were characterized and compared with serologically typical S.flexneri. One type of strain either displayed nonreacting typing or grouping sera, reacting strongly only with polyB antisera, which indicates this strain is S. flexneri (polyB:un). The second type displayed reactions with one of the typing sera (IV) and did not bind any grouping sera (IV:un). The remaining type of strain displayed a plural agglutination pattern, reacted with one typing sera (II), and bound with two grouping sera (II:(3)4,7(8)). Among these atypical strains IV:un and II:(3)4,7(8) strains showed higher multi-antibiotic resistance in ampicillin, streptomycin, and trimethoprim-sulfamethoxazole than typical strains. Furthermore, all II:(3)4,7(8) strains harbored integrons. This study suggests that these multiple antibiotic-resistant atypical S. flexneri are new subserotypes of S.flexneri that await further serological classification.

Background And Aims: The laxative lubiprostone has been shown to decrease intestinal permeability. We aimed to assess the safety and efficacy of lubiprostone administered for 48 weeks in patients with metabolic dysfunction-associated steatotic liver disease (MASLD).
Approach And Results: A randomised placebo-controlled trial was conducted in a specialised MASLD outpatient clinic at the National Hepatology and Tropical Medicine Research Institute, Cairo, Egypt.

Background: Cholesterol efflux capacity (CEC) of HDL (high-density lipoprotein) is inversely associated with incident cardiovascular events, independent of HDL cholesterol. Obesity is characterized by low HDL cholesterol and impaired HDL function, such as CEC. Bariatric surgery, including Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), broadly leads to improved cardiovascular outcomes, but impacts on risk factors differ by procedure, with greater improvements in weight loss, blood pressure, and glycemic control after RYGB, but greater improvements in HDL cholesterol and CEC levels after SG.

This study aims to improve the signal-to-noise ratio (SNR) of chemiluminescence immunoassay (CLIA) by increasing the amount of protein immobilized on the surface of the magnetic bead (MB). Proteins are macromolecules with three-dimensional structures, and merely increasing the density of functional groups on the two-dimensional surface of the MB cannot significantly enhance protein immobilization. Therefore, we grafted spatially extended functional polymer to not only increase the density of functional groups on the MB surface but also expand their distribution in three-dimensional space, ultimately increasing protein immobilization.

Background: Accurate data on the prognosis of bone metastases are necessary for appropriate treatment. Immune checkpoint inhibitors (ICIs) are widely used in the treatment of gene mutation-negative non-small cell lung cancer (GMN-NSCLC).
Aim: To investigate the prognostic factors in patients with bone metastases from GMN-NSCLC following ICI use.

Objective: The impact of cytomegalovirus (CMV) on inflammatory bowel disease (IBD) flares remains a matter of debate. This study aimed to evaluate patients with CMV infection who presented with IBD exacerbation in terms of diagnosis and treatment and investigate the importance of CMV DNA levels in colitis development.
Materials And Methods: Patients who were followed up with IBD and examined with clinical suspicion of CMV colitis at a university hospital between January 2016 and December 2021 were retrospectively scanned.
