Effects of Aging on Glucose and Lipid Metabolism in Mice.

Aging is accompanied by multiple molecular changes that contribute to aging associated pathologies, such as accumulation of cellular damage and mitochondrial dysfunction. Tissue metabolism can also change with age, in part, because mitochondria are central to cellular metabolism. Moreover, the cofactor NAD, which is reported to decline across multiple tissues during aging, plays a central role in metabolic pathways such as glycolysis, the tricarboxylic acid cycle, and the oxidative synthesis of nucleotides, amino acids, and lipids.

Impairment of lipid homeostasis causes lysosomal accumulation of endogenous protein aggregates through ESCRT disruption.

Protein aggregation increases during aging and is a pathological hallmark of many age-related diseases. Protein homeostasis (proteostasis) depends on a core network of factors directly influencing protein production, folding, trafficking, and degradation. Cellular proteostasis also depends on the overall composition of the proteome and numerous environmental variables.

Focusing on autism symptoms masks sex-specific needs of autistic children: An example from the Sydney Child Neurodevelopment Research Registry.

Studies have shown that there is a difference between biological sex at birth in autism spectrum disorder. There remains a lack of understanding about how the symptoms of autism differ between assigned males at birth and assigned females at birth. We looked at the presence of sex differences in a large group of autistic toddlers, children and adolescents, who were seen in a large diagnosis and assessment clinic.

Transradial-based thoracic branch endograft repair for thoracic aortic aneurysms experience at a suburban community hospital.

We present two cases where a transradial-based approach was used to implant thoracic branch aortic endografts to repair aortic aneurysms totally percutaneously. Both procedures were performed electively at a 330-bed suburban community hospital. No complications were associated with either procedure with both patients only requiring overnight observation and being discharged home the next day.
