Differences in cerebral structure among patients with amnestic mild cognitive impairment and patients with Alzheimer's disease.

Background: Brain has been shown to undergo progressive atrophy in patients with Alzheimer's disease (AD); however, more evidence is needed to elucidate how the brain structure changes during the progression to AD. Here, we observed differences in the cerebral structure among patients with amnestic mild cognitive impairment (aMCI) and patients with AD.

Methods: A total of 46 participants were selected and divided into AD, aMCI, and healthy control (HC) groups.

Self-delivering RNAi immunotherapeutic PH-762 silences PD-1 to generate local and abscopal antitumor efficacy.

Objective: Immunotherapeutic inhibition of PD-1 by systemically administered monoclonal antibodies is widely used in cancer treatment, but it may cause severe immune-related adverse events (irSAEs). Neoadjuvant PD-1 inhibition before surgery has shown promise in reducing recurrence by stimulating durable antitumor immunity. Local intratumoral (IT) immunotherapy is a potential strategy to minimize irSAEs, but antibodies have limited tumor penetration, making them less suitable for this approach.

Mental fatigue causes significant activation of the prefrontal cortex: A systematic review and meta-analysis of fNIRS studies.

Mental fatigue, a psychobiological prevalent and underestimated condition, is defined by increased lethargy and impaired concentration. This condition is not restricted by age and is exacerbated by various predisposing factors. Prolonged mental fatigue in occupational environments raises the probability of accidents or fatalities.

Aggregation-Induced Emission Luminogens for Plant Photodynamic Seed Sterilization.

Pathogen-carrying seeds can significantly impact plant growth and development and may lead to serious public health incidents. Modern agriculture heavily relies on synthetic chemical microbicides and physical methods to eradicate pathogens transmitted by plant seeds. To counteract the misuse of microbicides, a class of cationic amphiphilic aggregate-induced emission luminogens (AIEgens) are developed as photodynamic seed sterilization agents.

Modeling sub-exponential epidemic growth dynamics through unobserved individual heterogeneity: a frailty model approach.

Traditional compartmental models of epidemic transmission often predict an initial phase of exponential growth, assuming uniform susceptibility and interaction within the population. However, empirical outbreak data frequently show early stages of sub-exponential growth in case incidences, challenging these assumptions and indicating that traditional models may not fully encompass the complexity of epidemic dynamics. This discrepancy has been addressed through models that incorporate early behavioral changes or spatial constraints within contact networks.

Corticosteroids plus metformin versus corticosteroids as front-line treatment for patients with newly diagnosed ITP and pre-existing type 2 diabetes mellitus: A multicentre propensity score-matched study.

Corticosteroids are the standard first-line treatment for primary immune thrombocytopenia (ITP), with a high initial response but unsatisfactory sustained response (SR). Additionally, corticosteroids usually lead to hyperglycaemia especially in patients with pre-existing type 2 diabetes mellitus (T2DM). Besides reducing the blood glucose levels, metformin was found to have immunomodulatory effects.
