Objective: In this study, the aim was to evaluate the diagnostic effectiveness of more easily applicable and cost-effective serum biomarkers, such as neutrophil-to-lymphocyte ratio (NLR), platelet-tolymphocyte ratio (PLR), C-reactive protein (CRP) to albumin ratio (CAR), and CRP-to-lymphocyte ratio (CLR), instead of the endoscopic activity index (EAI) used to determine disease activation in ulcerative colitis (UC) patients.

Methods: Blood tests performed during the same period as colonoscopy were reviewed, and NLR, PLR, CAR, and CLR values were calculated. Based on the EAI score, patients with a score <4 were classified as having UC in remission, those with a score ≥4 as having active UC, and those with normal colonoscopy results as the control group.

Gene editing the BCL11A erythroid enhancer is a validated approach to fetal hemoglobin (HbF) induction for β-hemoglobinopathy therapy, though heterogeneity in edit allele distribution and HbF response may impact its safety and efficacy. Here, we compare combined CRISPR-Cas9 editing of the BCL11A +58 and +55 enhancers with leading gene modification approaches under clinical investigation. Dual targeting of the BCL11A +58 and +55 enhancers with 3xNLS-SpCas9 and two single guide RNAs (sgRNAs) resulted in superior HbF induction, including in sickle cell disease (SCD) patient xenografts, attributable to simultaneous disruption of core half E-box/GATA motifs at both enhancers.

Editing the +58 region of the BCL11A erythroid enhancer has shown promise in treating β-globin disorders. To address variations in fetal hemoglobin (HbF) response, we investigated editing both +58 and +55 enhancers. Rhesus macaques transplanted with edited hematopoietic stem/progenitor cells (HSPCs) following busulfan conditioning exhibited durable, high-level (∼90%) editing frequencies post transplantation with sustained HbF reactivation over 4 years, without hematological perturbations.

Objective: Scattered white spots (SWS) seen in the duodenum during esophagogastroduodenoscopy are rare lesions. The histopathologic examination of SWS lesions reveals normal duodenal mucosa (ND), chronic nonspecific duodenitis, and intestinal lymphangiectasia (IL). The intestinal epithelium, through its barrier function, is responsible for tightly controlling antigen traffic from the intestinal lumen to the submucosa.

Background/aims: Cholecystectomy, while generally safe with low perioperative morbidity and mortality, has been linked to an increase in metabolic disorders. Metabolic dysfunction-associated fatty liver disease (MAFLD) is a globally prevalent condition that leads to both hepatic and systemic complications. This study aimed to investigate the association between cholecystectomy and MAFLD.

Background: Cerebral venous sinus thrombosis (CVST) is an uncommon form of cerebrovascular disease. Although our understanding of CVST has improved significantly over the past decades, there has been no bibliometric analysis of CVST until now. We aimed to examine and visualize the hotspots and trends of the research related to CVST using a bibliometric analysis based on Citespace and provide new insights for scholars in their future researches in this area.

Osteoarthritis (OA) is a chronic and degenerative joint disease affecting more than 500 million patients worldwide with no disease-modifying treatment approved to date. Several publications report on the transforming growth factor β-activated kinase 1 (TAK1) as a potential molecular target for OA, with complementary anti-catabolic and anti-inflammatory effects. We report herein on the development of TAK1 inhibitors with physicochemical properties suitable for intra-articular injection, with the aim to achieve high drug concentration at the affected joint, while avoiding severe toxicity associated with systemic inhibition.

Named after the two-faced Roman god, Janus particles (JPs) are defined by their distinct dual chemical compositions on a single particle. Research on micron-sized JPs has yielded remarkable insights, showcasing their unique assembly behaviors both in bulk and at interfaces. However, significant challenges persist, particularly in the synthesis of smaller (<500 nm) JPs, which remains complex and difficult to scale up.

Binaural beats, or the perceptual auditory illusions created when simultaneously presenting two similar frequencies to each ear separately, have been used to reduce anxiety in various procedures. Unfortunately, no prior study involved preprocedure binaural music exposure among patients undergoing upper gastrointestinal endoscopy, and this study sought to investigate its effect on anxiety and tolerance among participants undergoing sedation-free upper gastrointestinal endoscopy. The prospective, controlled, randomized trial included the participation of 96 Turkish patients aged between 18 and 70 years who were scheduled for an upper gastrointestinal endoscopy, regardless of sex or illness, and were divided randomly into two different groups to undergo endoscopy, namely, the binaural beats group ( = 48) and a control group ( = 48).

Objective: This study aimed to compare serum levels of CD163, YKL-40, and VILIP-1 between children with autism spectrum disorder (ASD) and healthy controls, while also investigating their association with the severity of ASD and language development.

Methods: The study included 40 ASD-diagnosed patients (aged 18-72 months) and 40 age-matched healthy controls. Childhood Autism Rating Scale, Preschool Language Scale-4, and Ankara Development Screening Inventory were administered to children in the ASD group.

Interactively visualizing large finite element simulation data on High-Performance Computing (HPC) systems poses several difficulties. Some of these relate to unstructured data, which, even on a single node, is much more expensive to render compared to structured volume data. Worse yet, in the data parallel rendering context, such data with highly non-convex spatial domain boundaries will cause rays along its silhouette to enter and leave a given rank's domains at different distances.

Graphitic carbon nitride (g-CN) is an intriguing nanomaterial that exhibits photoconductive fluorescence properties under UV-visible light. Dopamine (DA) coating of g-CN prepared from melamine was accomplished via self-polymerization of DA as polydopamine (PDA). The g-CN was coated with PDA 1, 3, and 5 times repeatedly as (PDA@g-CN) in tris buffer at pH 8.

Article Synopsis
  • A study evaluates patients with antibodies against myelin oligodendrocyte glycoprotein (anti-MOG-IgG), assessing their clinical, radiological, and demographic characteristics in relation to conditions like optic neuritis and myelitis.
  • Among the 104 participants, the majority were women, and the most common diagnoses included NMOSD, isolated optic neuritis, and ADEM, with a notable percentage showing symptoms resembling MS.
  • Findings indicate that older patients (>40 years) experienced more severe disability and poorer responses to treatment, highlighting the significance of anti-MOG-IgG in diagnosing NMOSD in patients without anti-NMO antibodies.

Ex vivo resting culture is a standard procedure following genome editing in hematopoietic stem and progenitor cells (HSPCs). However, prolonged culture may critically affect cell viability and stem cell function. We investigated whether varying durations of culture resting times impact the engraftment efficiency of human CD34+ HSPCs edited at the BCL11A enhancer, a key regulator in the expression of fetal hemoglobin.

Stable, mixed-donor-recipient chimerism after allogeneic hematopoietic stem cell transplantation (HSCT) for patients with sickle cell disease (SCD) is sufficient for phenotypic disease reversal, and results from differences in donor/recipient-red blood cell (RBC) survival. Understanding variability and predictors of RBC survival among patients with SCD before and after HSCT is critical for gene therapy research which seeks to generate sufficient corrected hemoglobin to reduce polymerization thereby overcoming the red cell pathology of SCD. This study used biotin labeling of RBCs to determine the lifespan of RBCs in patients with SCD compared with patients who have successfully undergone curative HSCT, participants with sickle cell trait (HbAS), and healthy (HbAA) donors.
