Integrative deep immune profiling of the elderly reveals systems-level signatures of aging, sex, smoking, and clinical traits.

Background: Aging increases disease susceptibility and reduces vaccine responsiveness, highlighting the need to better understand the aging immune system and its clinical associations. Studying the human immune system, however, remains challenging due to its complexity and significant inter-individual variability.

Methods: We conducted an immune profiling study of 550 elderly participants (≥60 years) and 100 young controls (20-40 years) from the RESIST Senior Individuals (SI) cohort.

Effect of temperature on circadian clock functioning of trees in the context of global warming.

Plant survival in a warmer world requires the timely adjustment of biological processes to cyclical changes in the new environment. Circadian oscillators have been proposed to contribute to thermal adaptation and plasticity. However, the influence of temperature on circadian clock performance and its impact on plant behaviour in natural ecosystems are not well-understood.

Managing obesity in adults with type 1 diabetes.

As the prevalence of obesity has reached epidemic proportions, its prevalence has also increased among adults living with type 1 diabetes mellitus. Unlike the pathophysiologic relationship between obesity and type 2 diabetes mellitus, the relationship between obesity and type 1 diabetes mellitus, and management of obesity in the setting of type 1 diabetes mellitus, have not been well reviewed. In this article, we discuss the comprehensive management of obesity in adults with type 1 diabetes mellitus, focusing on medical nutrition therapy and adjunct therapies such as weight loss-promoting medications and metabolic/bariatric surgery.

Kardar-Parisi-Zhang universality class in the synchronization of oscillator lattices with time-dependent noise.

Systems of oscillators subject to time-dependent noise typically achieve synchronization for long times when their mutual coupling is sufficiently strong. The dynamical process whereby synchronization is reached can be thought of as a growth process in which an interface formed by the local phase field gradually roughens and eventually saturates. Such a process is here shown to display the generic scale invariance of the one-dimensional Kardar-Parisi-Zhang universality class, including a Tracy-Widom probability distribution for phase fluctuations around their mean.
