It has long been understood that many of the same manipulations that increase longevity in Caenorhabditis elegans also increase resistance to various acute stressors, and vice-versa; moreover these findings hold in more complex organisms as well. Nevertheless, the mechanistic relationship between these phenotypes remains unclear, and in many cases the overlap between stress resistance and longevity is inexact. Here we review the known connections between stress resistance and longevity, discuss instances in which these connections are absent, and summarize the theoretical explanations that have been posited for these phenomena.

Human CblC catalyzes the indispensable processing of dietary vitamin B by the removal of its β-axial ligand and an either one- or two-electron reduction of its cobalt center to yield cob(II)alamin and cob(I)alamin, respectively. Human CblC possesses five cysteine residues of an unknown function. We hypothesized that Cys149, conserved in mammals, tunes the CblC reactivity.

Introduction: Kabuki Syndrome (KS) is a rare genetic disorder characterized by distinctive facial features, intellectual disability, and multiple congenital anomalies. It is caused by pathogenic variants in the and genes. Despite its significant disease burden, there are currently no approved therapies for KS, highlighting the need for advanced research and therapeutic development.

Epidemiological evidence has shown that the regular ingestion of vegetables and fruits is associated with reduced risk of developing chronic diseases. The introduction of the 3Rs (replacement, reduction, and refinement) principle into animal experiments has led to the use of valid, cost-effective, and efficient alternative and complementary invertebrate animal models which are simpler and lower in the phylogenetic hierarchy. Caenorhabditis elegans (C.

In order to address the issue of tracking errors of collision Caenorhabditis elegans, this research proposes an improved particle filter tracking method integrated with cultural algorithm. The particle filter algorithm is enhanced through the integration of the sine cosine algorithm, thereby facilitating uninterrupted tracking of the target C. elegans.

Alzheimer's disease (AD) is the leading cause of dementia in the elderly, clinically characterized by memory loss, cognitive decline, and behavioral disturbances. Its pathogenesis is not fully comprehended but involves intracellular depositions of amyloid beta peptide (Aβ) and neurofibrillary tangles of hyperphosphorylated tau. Currently, pharmacological interventions solely slow the progression of symptoms.
