Dynamics of bacterial composition and association with quality formation and histamine accumulation during Antarctic krill fish sauce fermentation.

In this study, we first verified the feasibility of using Antarctic krill as a raw material for quick-brewed fish sauce, and the results showed that the amino acid nitrogen (AAN)and total soluble nitrogen(TSN) in the fermented 30 days fish sauce met the national level fish sauce standards, but the histamine content exceeded the maximum limit value of histamine in fish sauce (400 mg/kg) set by the International Codex Alimentarius Commission (CAC) and the European Union (EU). On this basis, the correlation between physicochemical indexes and bacterial communities during the fermentation of fish sauce was investigated using high-throughput sequencing, culture method. The correlation analyses revealed the relationship between bacterial communities and the quality and safety of fish sauce, and these studies will be helpful for the development of Antarctic krill fish sauce.

Sexually dimorphic mechanisms of VGLUT-mediated protection from dopaminergic neurodegeneration.

Parkinson's disease (PD) targets some dopamine (DA) neurons more than others. Sex differences offer insights, with females more protected from DA neurodegeneration. The mammalian vesicular glutamate transporter VGLUT2 and ortholog dVGLUT have been implicated as modulators of DA neuron resilience.

Comparative genomics reveals key molecular targets for mutant Pediococcus pentosaceus C23221 producing pediocin.

Listeria monocytogenes is a common microorganism that causes food spoilage. Pediocins are some biologically active peptides or proteins encoded by ribosomes, which have a strong antimicrobial activity against L. monocytogenes.

Wettability Control of Interfaces for High-Performance Organic Thin-Film Transistors by Soluble Insulating Polymer Films.

Organic small-molecule semiconductors have higher carrier mobility compared to polymer semiconductors, while the actual performances of these materials are susceptible to morphological defects and misalignment of crystalline grains. Here, a new strategy is explored to control the crystallization and morphologies of a solution-processed organic small-molecule semiconductor 2,7-dioctyl[1]benzothieno[3,2-][1]benzothiophene (C8-BTBT) using soluble polymer films to control the wettability of substrates. Different from the traditional surface modification method, the polymer layer as a modification layer is soluble in the semiconductor solution during the fabrication of organic thin-film transistors (OTFTs).

Functional Carbon Quantum Dots for Highly Sensitive Graphene Transistors for Cu Ion Detection.

Cu ions play essential roles in various biological events that occur in the human body. It is important to establish an efficient and reliable detection of Cu ions for people's health. The solution-gated graphene transistors (SGGTs) have been extensively investigated as a promising platform for chemical and biological sensing applications.

Negative Emotion Weakens the Degree of Self-Reference Effect: Evidence from ERPs.

We investigated the influence of negative emotion on the degree of self-reference effect using event-related potentials (ERPs). We presented emotional pictures and self-referential stimuli (stimuli that accelerate and improve processing and improve memory of information related to an individual's self-concept) in sequence. Participants judged the color of the target stimulus (self-referential stimuli).

Reward Promotes Self-Face Processing: An Event-Related Potential Study.

The present study adopted a reward-priming paradigm to investigate whether and how monetary reward cues affected self-face processing. Event-related potentials were recorded during judgments of head orientation of target faces (self, friend, and stranger), with performance associated with a monetary reward. The results showed self-faces elicited larger N2 mean amplitudes than other-faces, and mean N2 amplitudes increased after monetary reward as compared with no reward cue.

Electrophysiological correlation of the degree of self-reference effect.

The present study investigated neural correlations underlying the psychological processing of stimuli with various degrees of self-relevance. Event-related potentials were recorded for names that differ in their extent of relevance to the study participant. Participants performed a three-stimulus oddball task.
