Can ChatGPT Provide Useful Guidance to Assess the Current State of and Future Priorities for Aging Research in the Social Sciences?

The multifaceted implications of global population aging require regular assessments of the current state of aging-related social science research and the identification of potential future research priorities in this important area. Given the multi-, inter-, and transdisciplinary nature of this field, such assessments typically require the involvement of experts from diverse backgrounds to ensure a comprehensive picture and to synthesize understudied and newly emerging topics into a future research agenda. We explored to what extent ChatGPT (version GPT-4, OpenAI) might be a useful tool for synthesizing the current state of research and identifying promising future research areas, which could feed into expert panel discussions for priority setting.

Humoral waning kinetics against SARS-CoV-2 is dictated by disease severity and vaccine platform.

SARS-CoV-2 vaccine-acquired immunity provides robust cross-variant recognition, while infection-acquired immunity can be heterogenous, with disease severity often modulating post-recovery responses. We assessed antibody waning dynamics between infection- and vaccination-acquired immunity across variants of concern (VOC). mRNA vaccination induced potent, cross-VOC Spike recognition and functional responses, but waned more rapidly for Omicron Spike.

The long-term effects of cash transfer programmes on young adults' mental health: A quasi-experimental study of Colombia, Mexico and South Africa.

Poverty is associated with poorer mental health in early adulthood. Cash transfers (CTs) have been shown to improve child health and education outcomes, but it is unclear whether these effects may translate into better mental health outcomes as children reach young adulthood. Using a quasi-experimental approach that exploits variation across countries in the timing of national CT programme introduction, we examine whether longer exposure to CTs during childhood (0-17 years) reduces depressive symptoms in early adulthood (18-30 years).

Separation of 2,3-Butanediol from Fermentation Broth via Cyclic and Simulated Moving Bed Adsorption Over Nano-MFI Zeolites.

The biomass-based platform molecule 2,3-butanediol (2,3-BDO) has a wide range of applications in production of sustainable fuels, chemicals, synthetic rubber, and others. However, the selective separation of 2,3-BDO from multicomponent fermentation broths presents challenges due to its low concentration, high solubility in water, high boiling point, and presence of many other species. Here, we demonstrate remarkably selective enrichment and recovery of 2,3-BDO from a corn stover hydrolysate fermentation broth by a pure-silica nano-MFI-type zeolite adsorbent.

The evolutionary conserved miR-137/325 tandem mediates obesity-induced hypogonadism and metabolic comorbidities by repressing hypothalamic kisspeptin.

Background: Obesity-induced hypogonadism (OIH) is a prevalent, but often neglected condition in men, which aggravates the metabolic complications of overweight. While hypothalamic suppression of Kiss1-encoded kisspeptin has been suggested to contribute to OIH, the molecular mechanisms for such repression in obesity, and the therapeutic implications thereof, remain unknown.

Methods: A combination of bioinformatic, expression and functional analyses was implemented, assessing the role of the evolutionary-conserved miRNAs, miR-137 and miR-325, in mediating obesity-induced suppression of hypothalamic kisspeptin, as putative mechanism of central hypogonadism and metabolic comorbidities.
