Serum serotonin and histamine were examined for their effects on lymphocytic dystrophic processes. During an exacerbation, there was an increase in the plasma concentration of biogenic amines (BGA) in patients with atopic and infective-and-allergic bronchial asthma. The elevated levels of BGA affected the activity of lymphocytes that were, on an exacerbation, in the functional stress accompanied by a derangement of adaptive processes that ended in cell dystrophy.

Post-retrieval noradrenergic activation impairs subsequent memory depending on cortico-hippocampal reactivation.

When retrieved, seemingly stable memories can become sensitive to significant events, such as acute stress. The mechanisms underlying these memory dynamics remain poorly understood. Here, we show that noradrenergic stimulation after memory retrieval impairs subsequent remembering, depending on hippocampal and cortical signals emerging during retrieval.

This study employs a novel fiber optic biosensor based on S-tapered and waist extension techniques, as well as localized surface plasmon resonance (LSPR), to detect putrescine accurately. The gold nanoparticles (AuNPs) are fixed on the fiber to excite LSPR.

Recreational use of nitrous oxide (NO) has risen dramatically over the past decades. This study aimed to examine its rewarding effect and the underlying mechanisms. The exposure of mice to a subanesthetic concentration (20%) of NO for 30 min for 4 consecutive days paired with NO in the morning and paired with the air in the afternoon produced apparent rewarding behavior in the conditioned place preference (CPP) paradigm.

The DAF-2/insulin/insulin-like growth factor signaling (IIS) pathway plays an evolutionarily conserved role in regulating reproductive development, life span, and stress resistance. In Caenorhabditis elegans, DAF-2/IIS signaling is modulated by an extensive array of insulin-like peptides (ILPs) with diverse spatial and temporal expression patterns. However, the release dynamics and specific functions of these ILPs in adapting to different environmental conditions remain poorly understood.

Food Sci Nutr
January 2025
Traditionally fermented sufu is popular because of its flavor, abundance of nutrients, and long shelf life. However, traditional sufu is difficult to produce via industrial processes because of dominant microorganism attenuation during fermentation. Herein, specific protease-producing strains were isolated from traditional sufu.
