Article Synopsis
  • Aging can lead to sarcopenic obesity, a condition where individuals are obese while also experiencing muscle loss and decreased strength due to sarcopenia.
  • The study evaluated 156 older women to analyze the effects of obesity, sarcopenia, and sarcopenic obesity on body composition, functional performance, and muscle strength; results showed that 32.7% had obesity, 15.4% had sarcopenia, and 25% were classified as having sarcopenic obesity.
  • Findings revealed that women with sarcopenic obesity had worse physical performance and lower muscle-specific strength compared to those without, highlighting the need to consider muscle strength in diagnosing and addressing sarcopenic obesity in

Fruit juice processing can generate significant waste, but efficiently repurposing some of its byproducts not only reduces environmental impact but also adds value, thereby enhancing sustainability in the food industry. This work assesses the use of hydrocolloids in jam preparation and the influence of time and temperature on gelation in the presence of apple pomace. The effects of different processing conditions were analyzed using response surface methodology.

Metal-dependent formate dehydrogenases are very promising targets for enzyme optimization and design of bio-inspired catalysts for CO reduction, towards innovative strategies for climate change mitigation. For effective application of these enzymes, the catalytic mechanism must be better understood, and the molecular determinants clarified. Despite numerous studies, several doubts persist, namely regarding the role played by the possible dissociation of the SeCys ligand from the Mo/W active site.

Delirium presents a significant clinical challenge, primarily due to its profound impact on patient outcomes and the limitations of the current diagnostic methods, which are largely subjective. During the COVID-19 pandemic, this challenge was intensified as the frequency of delirium assessments decreased in Intensive Care Units (ICUs), even as the prevalence of delirium among critically ill patients increased. The present study evaluated how the serum molecular fingerprint, as acquired by Fourier-Transform InfraRed (FTIR) spectroscopy, can enable the development of predictive models for delirium.

Robust data normalization and analysis are pivotal in biomedical research to ensure that observed differences in populations are directly attributable to the target variable, rather than disparities between control and study groups. ArsHive addresses this challenge using advanced algorithms to normalize populations (e.g.
