CX3CR1-transduced regulatory T cells (Tregs) have shown potential in reducing neuroinflammation by targeting microglial activation. Reactive microglia are implicated in neurological disorders, and CX3CR1-CX3CL1 signaling modulates microglial activity. The ability of CX3CR1-transduced Tregs to inhibit LPS-induced neuroinflammation was assessed in animal models.

Article Synopsis
  • Advances in the development of amyloid β-specific human Tregs (Aβ-hTreg) show promise for treating Alzheimer's disease (AD), despite challenges with Treg selection and expansion.
  • A successful ex vivo expansion method was established, leading to a phase 1 clinical trial with six Alzheimer's patients that evaluated the safety and initial efficacy of Aβ-hTreg.
  • Results indicated improved cognitive function and safety of the treatment in mice, while no significant toxicity was observed in patients, suggesting a potential pathway for future AD clinical trials.

Article Synopsis
  • - This study aimed to determine if tegoprazan is as effective as lansoprazole in healing erosive esophagitis (EE) within four weeks, with a specific focus on rapid mucosal healing and symptom relief by week two.
  • - In a randomized trial of 218 patients, results showed that tegoprazan had significantly higher healing rates compared to lansoprazole at both two weeks (88.4% vs. 82.6%) and four weeks (95.2% vs. 86.2%).
  • - The findings suggest that tegoprazan is superior to lansoprazole for treating EE, but more research is needed to fully understand its advantages, especially for severe cases

  • AHPND (Acute hepatopancreatic necrosis disease) is a major threat to the global shrimp industry, with new mutant strains causing concern over potential misdiagnosis and unexpected virulence.
  • This study reports the first identification of a natural mutant strain (20-082A3) in Korea, closely related to a previously virulent strain (19-021-D1) from a 2019 outbreak, sharing over 99.9% similarity in plasmids and the same genetic typing.
  • The newly identified mutant strain (20-082A3) does not cause symptoms or mortality in shrimp, indicating a need for ongoing surveillance of AHPND-causing pathogens in Korea and more research into the implications of this

Article Synopsis
  • - Colonoscopy is crucial for early colorectal cancer detection, but the procedure's discomfort often necessitates sedation, prompting a study on different sedation protocols.
  • - In a trial with 51 patients, two groups received either midazolam with propofol or midazolam with pethidine, finding similar safety and effectiveness between both regimens.
  • - The midazolam and propofol group experienced fewer postural changes and needed less manual compression, suggesting it led to a more comfortable procedure without significant differences in pain or overall satisfaction.

This study aimed to determine whether urinary creatinine excretion rate (CER), a marker of muscle mass, is associated with diabetic retinopathy in individuals with type 2 diabetes and to ascertain whether this putative association depends on body mass index (BMI). This cross sectional study evaluated 2035 individuals with type 2 diabetes. Twenty-four-hour urine was collected.

  • Hyperinflammation plays a key role in sepsis, impacting outcomes positively and negatively; researchers previously identified exosome-based super-repressor IκBα (Exo-srIκB) as a promising treatment.
  • In a rat model simulating polymicrobial sepsis, the study tested Exo-srIκB on different severities of sepsis and at various time points post-infection.
  • Results showed significant survival benefits with Exo-srIκB, particularly when given 6 hours post-infection in severe sepsis, along with reductions in harmful cytokines and improvements in critical blood markers.

Patients with chronic constipation (CC) usually complain of mild to severe symptoms, including hard or lumpy stools, straining, a sense of incomplete evacuation after a bowel movement, a feeling of anorectal blockage, the need for digital maneuver to assist defecation, or reduced stool frequency. In clinical practice, healthcare providers need to check for 'alarm features' indicative of a colonic malignancy, such as bloody stools, anemia, unexplained weight loss, or new-onset symptoms after 50 years of age. In the Seoul Consensus on the diagnosis and treatment of chronic constipation, the Bristol stool form scale, colonoscopy, and digital rectal examination are useful for objectively evaluating the symptoms and making a differential diagnosis of the secondary cause of constipation.

Background/aims: Bile reflux (BR) can influence the gastric environment by altering gastric acidity and possibly the gastric microbiota composition. This study investigated the correlation between bile acids and microbial compositions in the gastric juice of 50 subjects with differing gastric pathologies.

Methods: This study included 50 subjects, which were categorized into three groups based on the endoscopic BR grading system.

Colorectal cancer (CRC) stands as a major cause of cancer-related mortality globally, accounting for approximately 881,000 deaths each year. Traditional approaches such as chemotherapy and surgery have been the primary treatment modalities, yet the outcomes for patients with metastatic CRC are often unsatisfactory. Recent research has focused on targeting the pathways involved in oxidative stress, inflammation, and metastasis to enhance the survival of CRC patients.

The increasing economic losses associated with growth retardation caused by (EHP), a microsporidian parasite infecting penaeid shrimp, require effective monitoring. The internal transcribed spacer (ITS)-1 region, the non-coding region of ribosomal clusters between 18S and 5.8S rRNA genes, is widely used in phylogenetic studies due to its high variability.

Gastric cancer, a leading cause of cancer-related deaths globally, necessitates effective and early detection and treatment strategies. Endoscopic resection techniques, particularly endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD), have evolved significantly, enhancing the treatment of gastric neoplasms. Underwater endoscopic mucosal resection (UEMR) is a widely used technique for the resection of duodenal and colorectal neoplasms.

Amine derivatives are signature organic compounds generated from rotten protein food. Thus, sensitive detection of the presence of amines in protein foods can be a critical technique for monitoring their quality. In this study, we develop an organic chemosensor probe, 4-(2-(3-(dicyanomethylene)- 5,5-dimethylcyclohex-1-en-1-yl)vinyl)-N,N-diethylbenzenaminium chloride (DEAH), to effectively detect amines through discernible bimodal (colorimetric and fluorometric) changes.

Introduction: The binary PirA/PirB toxin expressed by (PirAB) is a virulent complex that causes acute hepatopancreatic necrosis disease (AHPND) in shrimps, affecting the global shrimp farming industry. AHPND is currently diagnosed by detecting and genes by PCR; however, several strains do not produce the two toxins as proteins. Thus, an immunoassay using antibodies may be the most effective tool for detecting toxin molecules.
