Self-Reported Nonceliac Gluten Sensitivity in Italian Young Adults: A Cross-Sectional Study. A Dietary Fad?

Introduction: In different countries, the exact prevalence of people that refer symptoms after gluten ingestion is increasing and the unavailability of reliable laboratory tests to diagnose the condition known as nonceliac gluten sensitivity (NCGS) has opened the door to the spread of survey-based studies to hypothesize a prevalence of this condition with highly discordant results. We aim to describe the attitude toward gluten consumption in a large population of young adults in Italy.

Methods: A questionnaire-based cross-sectional study was conducted in 13 Italian cities to investigate the dietary attitudes of more than 9,400 people distributed throughout the country about gluten consumption.

Pharmacological Enhancement of Adult Hippocampal Neurogenesis Improves Behavioral Pattern Separation in Young and Aged Mice.

Background: Impairments in behavioral pattern separation (BPS)-the ability to distinguish between similar contexts or experiences-contribute to memory interference and overgeneralization seen in many neuropsychiatric conditions, including depression, anxiety, PTSD, dementia, and age-related cognitive decline. While BPS relies on the dentate gyrus and is sensitive to changes in adult hippocampal neurogenesis (AHN), its significance as a pharmacological target has not been tested.

Methods: In this study, we applied a human neural stem cell high-throughput screening cascade to identify compounds that increase human neurogenesis.

AGO2-RIP-Seq reveals miR-34/miR-449 cluster targetome in sinonasal cancers.

Sinonasal tumours are heterogeneous malignancies, presenting different histological features and clinical behaviour. Many studies emphasize the role of specific miRNA in the development and progression of cancer, and their expression profiles could be used as prognostic biomarkers to predict the survival. Recently, using the next-generation sequencing (NGS)-based miRNome analysis the miR-34/miR-449 cluster was identified as miRNA superfamily involved in the pathogenesis of sinonasal cancers (SNCs).

Keratinocytes Exposed to Blue or Red Light: Proteomic Characterization Showed Cytoplasmic Thioredoxin Reductase 1 and Aldo-Keto Reductase Family 1 Member C3 Triggered Expression.

Several cell-signaling mechanisms are activated by visible light radiation in human keratinocytes, but the key regulatory proteins involved in this specific cellular response have not yet been identified. Human keratinocytes (HaCaT cells) were exposed to blue or red light at low or high irradiance for 3 days in cycles of 12 h of light and 12 h of dark. The cell viability, apoptotic rate and cell cycle progression were analyzed in all experimental conditions.
