These updates clarify our understanding of how MRE11 expression may be utilized in future stratification of cancer patients for radiotherapy, and how it may be leveraged in shaping novel radiosensitization strategies.The effects of senescence on geriatric disorders are well explored, but how it influences infections in the elderly is poorly addressed. Here, we show that several anti-microbial responses are elevated in senescent epithelial cells and old mice, which results in decreased bacterial survival in the host after infection. We identify higher levels of iNOS as a crucial host response and show that p38 MAPK in senescent epithelial cells acts as a negative regulator of iNOS transcription. However, in older mice, the ability to impede bacterial infection does not result in enhanced survival, possibly because elevated pro-inflammatory responses are not countered by a robust host protective anti-inflammatory response. Overall, while addressing an alternate advantage of senescent cells, our study demonstrates that infection-associated morbidity in the elderly may not be the sole outcome of pathogen loads but may also be influenced by the host's ability to resolve inflammation-induced damage.Action observation (AO) and motor imagery (MI) have been used separately across different populations to alleviate movement impairment. Recently these two forms of covert motor simulation have been combined (combined action observation and motor imagery; AOMI), resulting in greater neurophysiological activity in the motor system, and more favourable behavioural outcomes when compared to independent AO and MI. Halofuginone This review aims to outline how some of the neural deficits associated with developmental coordination disorder (DCD) are evident during AO and MI, and highlight how these motor simulation techniques have been used independently to improve motor skill learning in children in this population. The growing body of evidence indicating that AOMI is superior to the independent use of either AO and MI is then synthesised and discussed in the context of children with DCD. To conclude, recommendations to optimise the delivery of AOMI for children with DCD are provided and future avenues for research are highlighted.Latrophilin-3 (LPHN3), a G-protein-coupled receptor belonging to the adhesion subfamily, is a regulator of synaptic function and maintenance in brain regions that mediate locomotor activity, attention, and memory for location and path. Variants of LPHN3 are associated with increased risk for attention deficit hyperactivity disorder (ADHD) in some patients. Here we review the role of LPHN3 in the central nervous system (CNS). We describe synaptic localization of LPHN3, its trans-synaptic binding partners, links to neurodevelopmental disorders, animal models of Lphn3 disruption in different species, and evidence that LPHN3 is involved in cognition as well as activity and attention. The evidence shows that LPHN3 plays a more significant role in neuroplasticity than previously appreciated.Similarity-based categorization, as an important cognitive skill, can be performed by abstracting a categories' central tendency, the so-called prototype, or by memorizing individual exemplars of a category. The flexible selection of an appropriate strategy is crucial for effective cognitive functioning. The detail-focused cognitive style in individuals with autism spectrum disorders (ASD) has been hypothesized to specifically impair prototype-based categorization but to leave exemplar-based categorization unimpaired. We first give an overview of approaches to investigate prototype-based abstraction in the prototype-distortion task, with an emphasis on model-based approaches suitable to discern the two strategies on the individual level. The second part summarizes literature speaking to prototype-based categorization in ASD using that task. Despite considerable inconsistencies, most studies appear to confirm that autistic individuals have more difficulties to perform prototype-distortion tasks than non-autistic individuals. We highlight how inconsistencies in literature can be resolved by taking the differences in task designs into account. The current review illustrates the need for sensitive computational approaches, suitable to detect hidden individual differences and potential compensatory strategies.Among all major organs, the brain is one of the most susceptible to the inexorable effects of aging. Throughout the last decades, several studies in human cohorts and animal models have revealed a plethora of age-related changes in the brain, including reduced neurogenesis, oxidative damage, mitochondrial dysfunction and cell senescence. As the main immune effectors and first responders of the nervous tissue, microglia are at the center of these events. These cells experience irrevocable changes as a result from cumulative exposure to environmental triggers, such as stress, infection and metabolic dysregulation. The age-related immunosenescent phenotype acquired by microglia is characterized by profound modifications in their transcriptomic profile, secretome, morphology and phagocytic activity, which compromise both their housekeeping and defensive functions. As a result, aged microglia are no longer capable of establishing effective immune responses and sustaining normal synaptic activity, directly contributing to age-associated cognitive decline and neurodegeneration. This review discusses how lifestyle and environmental factors drive microglia dysfunction at the molecular and functional level, also highlighting possible interventions to reverse aging-associated damage to the nervous and immune systems.
We investigated the association between inflammatory markers and muscle strength in older adults according to the presence or absence of obesity. Dynapenia is the age-related decline in muscle strength and results in negative outcomes to older adults. Accordingly, obesity is more prevalent throughout aging and is associated with comorbidities, such as type 2 diabetes, dyslipidemia and cardiovascular diseases. Both dynapenia and obesity are strongly linked to chronic inflammation, sharing common signaling pathways.

We recruited 247 older adults aged 60 or older and collected sociodemographic, anthropometric and metabolic data. Dynapenia was diagnosed according to the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) criteria. Circulating inflammatory cytokines were measured in plasma using a multiplex panel kit. Anthropometric, sociodemographic, lipid profile, and fasting blood glucose were also assessed.

Dynapenic participants were predominantly males (74.4%), had insufficiently active lifestyle and higher IL-10 plasma levels (0.
