Published: September 2011

A common polymorphism (rs3851179) in the PICALM (phosphatidylinositol-binding clathrin assembly protein) gene has been recently associated with reduced risk of developing late-onset Alzheimer’s disease (LOAD). We analyzed the genotype and allele distributions of the PICALM polymorphism in 813 Italian subjects, including LOAD patients and centenarians. The segregation of the PICALM rs3851179 showed no statistically significant difference between LOAD cases and controls. The implication of a genetic variant at PICALM is confirmed for the first time, in centenarians, thus suggesting a possible role in longevity.

Introduction: Age-associated depletion in nicotinamide adenine dinucleotide (NAD+) concentrations has been implicated in metabolic, cardiovascular, and neurodegenerative disorders. Supplementation with NAD+ precursors, such as nicotinamide riboside (NR), offers a potential therapeutic avenue against neurodegenerative pathologies in aging, Alzheimer's disease, and related dementias. A crossover, double-blind, randomized placebo (PBO) controlled trial was conducted to test the safety and efficacy of 8 weeks' active treatment with NR (1 g/day) on cognition and plasma AD biomarkers in older adults with subjective cognitive decline and mild cognitive impairment.

Faculty of Medicine, Imperial College London, London SW7 2AZ, United Kingdom.

Pediatric pancreatic tumors, though rare, pose significant diagnostic and management challenges. The recent, 22-year nationwide survey on pediatric pancreatic tumors in Japan by Makita offers valuable insights into this uncommon entity, revealing striking geographical variations and questioning current treatment paradigms. This editorial commentary analyzes the study's key findings, including the predominance of solid pseudopapillary neoplasms and their younger age of onset, which contrast sharply with Western data.

Expression, purification and immunogenicity analyses of receptor binding domain protein of severe acute respiratory syndrome coronavirus 2 from delta variant.

Institute of Pathogenic Microbiology, College of Biological Science and Engineering, and Nanchang Key Laboratory of Animal Virus and Genetic Engineering, Jiangxi Agricultural University, Nanchang, China.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the COVID-19 pandemic. The receptor binding domain (RBD), located at the spike protein of SARS-CoV-2, contains most of the neutralizing epitopes during viral infection and is an ideal antigen for vaccine development. In this study, bioinformatic analysis of the amino acid sequence data of SARS-CoV-2 RBD protein for the better understanding of molecular characteristics was performed.
