Self-replicating RNA (srRNA) technology, in comparison to mRNA vaccines, has shown dose-sparing by approximately 10-fold and more durable immune responses. However, no improvements are observed in the adverse events profile. Here, we develop an srRNA vaccine platform with optimized non-coding regions and demonstrate immunogenicity and safety in preclinical and clinical development.

Purpose: This study assessed the measurements of the medial posterior tibial slope (MPTS) using long radiographs and three-dimensional (3D) computed tomography (CT) scans and compared them to measurements taken on short lateral knee radiographs. The study aimed to identify whether the at-risk slope measurements previously defined on the short radiographs would be similar to long radiographs and 3D CT scans.

Methods: A retrospective radiological review of 52 cases, who underwent planning for a slope-changing high tibial osteotomy and had short and long lateral radiographs and 3D CT scans of the tibia.

Kidney fibrosis is the common pathological pathway in progressive chronic kidney disease (CKD), and current treatments are largely ineffective. The C-X-C chemokine receptor 4 (CXCR4) is crucial to fibrosis development. By using neural cell adhesion molecules as scaffolds with binding loops that mimic the shape of shark antibodies, fully humanized single-domain i-bodies have been developed.

Article Synopsis
  • Aberrant angiogenesis may contribute to cognitive decline and could serve as a therapeutic target for dementia prevention, though most prior studies have focused on animal models.
  • This study evaluated the relationship between blood markers of angiogenesis and cognitive aging in a sample of 435 older adults, revealing significant associations that varied by sex, particularly in younger women compared to men.
  • Results indicated that higher levels of certain angiogenic markers were linked to better executive function and less brain atrophy, suggesting the potential for targeting angiogenesis in addressing age-related cognitive impairment.

Endometrial atypical hyperplasia (EAH) is a premalignant condition with a substantial risk of progression to endometrial cancer (EC), with the endometrioid subtype being the most common. EAH is characterized by abnormal endometrial gland proliferation and cellular atypia, often resulting from prolonged unopposed estrogen exposure. This review aims to explore the clinical significance of EAH, its risk of progression to EC, and the current approaches to management.

Background: Emotional eating has been linked to childhood obesity. A variety of emotions often trigger this form of eating, which has been associated with stress-induced overeating, loss of control eating, and binge eating in children. However, research on how maternal immigration status and feeding practices influence emotional eating in children within Asian contexts is sparse.

Background And Aims: This study aimed to evaluate the association between pregnancy and aortic complications and determine related maternal and neonatal outcomes.

Methods: Records of pregnancies and neonatal deliveries from the Taiwan National Health Insurance Research Database from 2000 to 2020 were retrieved. The incidence rate ratio (IRR) was calculated to evaluate the risk factors for aortic events.

Background: Neoadjuvant chemotherapy (NAC) can provide improved survival outcomes in pancreatic ductal adenocarcinoma (PDAC) patients who respond to treatment, but currently available biomarkers cannot reliably predict NAC response. This study aimed to determine the potential of a previously identified diagnostic and prognostic biomarker panel (i.e.

Article Synopsis
  • - The study focused on how chick retinal pigment epithelium (RPE) gene expression of BMPs (Bone Morphogenetic Proteins) changes during recovery after short-term optical treatments, including lens wear and form deprivation.
  • - White-Leghorn chicks were subjected to different lenses or diffusers for various durations, and then their recovery was monitored in terms of refractive errors and changes in choroidal thickness (ChT) over 96 hours.
  • - Key findings indicated that BMP2 gene expression significantly increased with +10 D lens treatment shortly after application, while -10 D and form deprivation treatments led to a decrease in BMP2 expression, with recovery times being notably different between treatments.

Article Synopsis
  • - Dofetilide, a class III antiarrhythmic, is used to treat atrial fibrillation and flutter, and has been applied off-label for ventricular arrhythmias like PVCs and VTs.
  • - In a study involving 81 patients, dofetilide initiation showed a significant decrease in PVC burden, but was discontinued in some cases due to QT prolongation and lack of efficacy.
  • - Overall, 72% of patients had to stop dofetilide due to inefficacy or intolerance, and there was no significant difference in event-free survival between those treated with dofetilide and those who weren't.

Western blot is a popular biomolecular analysis method for measuring the relative quantities of independent proteins in complex biological samples. However, variability in quantitative western blot data analysis poses a challenge in designing reproducible experiments. The lack of rigorous quantitative approaches in current western blot statistical methodology may result in irreproducible inferences.

  • - Acinar cystic transformation (ACT) is a rare, non-cancerous cystic lesion in the pancreas that's often confused with more serious conditions like intraductal papillary mucinous neoplasms (IPMNs).
  • - All known cases of ACT are benign and have not shown any signs of recurrence or cancer development, which complicates preoperative diagnosis.
  • - The Fukuoka guidelines assist in managing IPMNs, and in this case, a patient was misdiagnosed with a side-branch IPMN and underwent a Whipple's procedure; the report emphasizes the challenges in correct diagnosis and the tools available to healthcare professionals.

Introduction: This study examined the association between current co-use of cannabis and cigarettes in the past 30 days, and subsequent cigarette discontinuation (past 30-day point prevalence abstinence) among U.S. adults with established cigarette use in the Population Assessment of Tobacco and Health (PATH) Study.

This study investigated the effectiveness of quitline service intensity (high vs. low) on past 30-day tobacco abstinence at 7-months follow-up, using observational data from the Oklahoma Tobacco Helpline (OTH) between April 2020 and December 2021. To assess the impact of loss to follow-up and non-random treatment assignment, we fit the parameters of a marginal structural model to estimate inverse probability weights for censoring (IPCW) and treatment (IPTW) and combined (IPCTW).

Anaplastic thyroid cancer (ATC), a rare and highly aggressive malignancy, is characterized by an exceptionally poor prognosis, where the majority of patients present with extensive local invasion and/or distant metastases. 20-30% of ATCs harbor the BRAF-V600E mutation. Neoadjuvant BRAF-targeted therapy may have the potential to downstage and facilitate surgical resection for patients with locally advanced and unresectable primary tumors with BRAF mutation and may convey a survival advantage in those with metastatic disease.

Article Synopsis
  • Descemet's Stripping Only (DSO) is a surgical technique that relies on the migration of corneal endothelial cells (CEnCs) to close wounds, and ripasudil, a ROCK inhibitor, may enhance this process.
  • Research found that ripasudil significantly improves the migration and wound healing of both normal and Fuchs endothelial corneal dystrophy (FECD) cells, specifically boosting the activity of certain proteins associated with cell mobility.
  • Ex vivo experiments showed that ripasudil treatment led to better migration and proliferation of CEnCs, suggesting it could be a valuable addition to DSO procedures by improving healing outcomes in the corneal environment.

We develop a novel metal contact approach using an antimony (Sb)-platinum (Pt) bilayer to mitigate Fermi-level pinning in 2D transition metal dichalcogenide channels. This strategy allows for control over the transport polarity in monolayer WSe devices. By adjustment of the Sb interfacial layer thickness from 10 to 30 nm, the effective work function of the contact/WSe interface can be tuned from 4.

Objectives: There is a paucity of data regarding the use of neoadjuvant therapy in pancreatic body or tail ductal adenocarcinomas. Given the differing tumor biology and aggressive nature of pancreatic body or tail adenocarcinomas, patients presenting with these tumors may benefit from upfront resection.

Methods: A retrospective cohort study was performed analyzing patients who underwent distal pancreatectomy for pancreatic ductal adenocarcinoma between January 2013 and June 2022.
