Celecoxib, a selective COX-2 inhibitor, has demonstrated anti-liver cancer effects in various preclinical models and clinical traits. However, prolonged use of celecoxib can lead to drug resistance, necessitating higher doses to maintain efficacy, which often results in severe side effects, limiting its clinical application. This study aimed to identify strategies to overcome celecoxib resistance in liver cancer.

Proteomics has become a transformative tool for species and sex determination. This study introduces a novel methodology that integrates amelogenin (Amel) and enamelin (Enam) proteins extracted from the tooth enamel of caprines. Since morphologically, osteological remains of sheep and goats often cannot be easily discriminated, we developed our method on both modern domestic sheep () and goats () to establish unique proteomic signatures for each species for sex and species identification.

Background: Homozygous familial hypercholesterolemia (HoFH) is a rare disease characterized by loss of low-density lipoprotein receptor (LDLR) function, an extreme elevation of circulating low-density lipoprotein cholesterol (LDL-C) from birth and substantially reduced life expectancy, if untreated. Patients with HoFH are frequently diagnosed late and have a markedly elevated risk of premature atherosclerotic cardiovascular disease (ASCVD).

Sources Of Material: The current European Atherosclerosis Society consensus statement on the treatment of HoFH recommends an LDL-C goal of <55 mg/dL for adults with ASCVD or major ASCVD risk factors, <70 mg/dL for adults without ASCVD risk factors, and <115 mg/dL for pediatric patients without ASCVD.

Introduction: Increased fecal protease activity, which may induce visceral hypersensitivity, has been observed in patients with irritable bowel syndrome (IBS). Serine proteases modulate FK506 binding protein (FKBP)-type peptidylprolyl cis-trans isomerase (PPIase) activity associated with immune and glucocorticoid receptor functions. The aim was to investigate whether camostat mesilate (CM), a serine protease inhibitor, modifies fecal bacterial function related to FKBP-type PPIases in patients with IBS.

Background And Aims: Chronic hepatitis D infection is the most severe form of viral hepatitis and can rapidly progress to cirrhosis or hepatocellular carcinoma. Despite recommendations for systematic screening of hepatitis B surface antigen (HBsAg)-positive individuals, data from real-world studies have reported a low frequency of hepatitis D (or delta) virus (HDV) screening. Our cross-sectional analysis evaluated the diagnostic cascade for hepatitis D infection in tertiary centres and described the characteristics of HDV-positive patients.

The high genetic diversity of hepatitis C virus (HCV) has led to the emergence of eight genotypes and a large number of subtypes in limited geographical areas. Currently approved pangenotypic DAA regimens have been designed and developed to be effective against the most common subtypes (1a, 1b, 2a, 2b, 2c, 3a, 4a, 5a and 6a). However, large populations living in Africa and Asia, or who have migrated from these regions to industrialised countries, are infected with 'unusual', non-epidemic HCV subtypes, including some that are inherently resistant to currently available direct-acting antiviral (DAA) drugs due to the presence of natural polymorphisms at resistance-associated substitution positions.

Institute of Soil, Water and Environmental Sciences, Volcani Center, Agricultural Research Organization, Rishon LeZion, Israel.

Under most conditions tight stomatal regulation in grapevines (Vitis vinifera) avoids xylem embolism. The current study evaluated grapevine responses to challenging scenarios that might lead to leaf embolism and consequential leaf damage. We hypothesized that embolism would occur if the vines experienced low xylem water potential (Ψx) shortly after bud break or later in the season under a combination of extreme drought and heat.

Article Synopsis
  • A study investigated the prevalence of unusual HCV genotype 1 subtypes in patients who did not achieve sustained virological response after first-line antiviral treatment, focusing on a population with significant representation from sub-Saharan Africa.
  • Among 640 treatment failures, 7.3% involved patients with these unusual genotypes, who exhibited genetic polymorphisms leading to reduced effectiveness of direct-acting antivirals.
  • The findings suggest that while these patients are less likely to respond to initial treatment, retreatment with a specific combination of antiviral drugs is usually effective in achieving a cure.
