Introduction: Corneal confocal microscopy (CCM) detects neurodegeneration in mild cognitive impairment (MCI) and dementia and identifies subjects with MCI who develop dementia. This study assessed whether abnormalities in corneal endothelial cell (CEC) morphology are related to corneal nerve morphology, brain volumetry, cerebral ischemia, and cognitive impairment in MCI and dementia.

Methods: Participants with no cognitive impairment (NCI), MCI, and dementia underwent CCM to quantify corneal endothelial cell density (CECD) and area (CECA), corneal nerve fiber morphology, magnetic resonance imaging (MRI) brain volumetry, and severity of brain ischemia.

In recent years, there has been a growing interest in developing a distinguished alternative to human consumption of animal-based proteins. The application of lentil proteins in the food industry is typically limited due to their poor solubility and digestibility. An innovative method of balancing lentil-whey protein (LP-WP) complexes with higher-quality protein properties was established to address this issue, which coupled a pH-shifting approach with fermentation treatment.

Article Synopsis
  • Hepatitis C Virus (HCV) is a serious bloodborne virus causing liver disease, and currently, there are no effective vaccines to prevent its spread, highlighting the importance of understanding T cell epitopes (TCEs) in immune response.
  • TCellPredX is a new prediction tool designed to identify TCEs related to HCV by using advanced machine learning techniques and a variety of feature encodings, which together improve the predictive accuracy of TCE identification.
  • The tool has demonstrated high accuracy scores (0.900 and 0.897) in identifying relevant peptides for vaccine development, establishing TCellPredX as a significant resource for future research aimed at creating an effective HCV vaccine.

  • Langerhans cell histiocytosis (LCH) is a rare disorder marked by the abnormal buildup of dendritic histiocytes in tissues, often presenting as single- or multi-system diseases, particularly affecting adults.
  • In a reported case, a 46-year-old woman experienced back pain, motor and sensory deficits, and was diagnosed with a compression fracture in the spine, alongside signs of central nervous system and salivary gland involvement.
  • The patient underwent surgical intervention that included decompression and a biopsy, confirming the presence of LCH, highlighting the complexity and rarity of adult-onset LCH with extensive system involvement.

Metaproteomics is a valuable approach to characterize the biological functions involved in the gut microbiota (GM) response to dietary interventions. Ketogenic diets (KDs) are very effective in controlling seizure severity and frequency in drug-resistant epilepsy (DRE) and in the weight loss management in obese/overweight individuals. This case study provides proof of concept for the suitability of metaproteomics to monitor changes in taxonomic and functional GM features in an individual on a short-term very low-calorie ketogenic diet (VLCKD, 4 weeks), followed by a low-calorie diet (LCD).

Laboratory of Human Genetics & Therapeutics, Genome Institute of Singapore (GIS), A(∗)STAR, Singapore, Singapore; Laboratory of Human Genetics & Therapeutics, BESE, KAUST, Thuwal, Saudi Arabia; Department of Physiology, Cardiovascular Disease Translational Research Programme, Yong Loo Lin School of Medicine, National University of Singapore, Singapore, Singapore. Electronic address:

Four genes-DAND5, PKD1L1, MMP21, and CIROP-form a genetic module that has specifically evolved in vertebrate species that harbor motile cilia in their left-right organizer (LRO). We find here that CIROZ (previously known as C1orf127) is also specifically expressed in the LRO of mice, frogs, and fish, where it encodes a protein with a signal peptide followed by 3 zona pellucida N domains, consistent with extracellular localization. We report 16 individuals from 10 families with bi-allelic CIROZ inactivation variants, which cause heterotaxy with congenital heart defects.
