Surfactin's impact on gut microbiota and intestinal tumor cells.

Surfactin exhibits multifunctional properties, including antimicrobial, anti-inflammatory, and antitumor activities, positioning it as a promising novel food additive. However, its specific effects on the gut environment remain largely unexplored. To investigate this, we conducted in vitro fermentation simulations to assess the impact of surfactin on gut microbiota.

Comparative effects of four types of resistant starch on the techno-functional properties of low-fat meat emulsions.

The behavior of resistant starch (RS) in meat matrix depends largely on its type. Hence, the comparative impacts of high amylose corn starch (RS2), retrograded starch (RS3), acetylated starch (RS4) and high amylose-lauric acid complex (RS5) on water-fat binding capacities, texture, color and microstructure of low-fat meat emulsions were investigated. Four types of RS improved water retention, emulsion stability, textural properties and brightness of low-fat meat emulsions, displaying even better potential than inulin (positive control).

Learning Contrast-Enhanced Shape-Biased Representations for Infrared Small Target Detection.

Detecting infrared small targets under cluttered background is mainly challenged by dim textures, low contrast and varying shapes. This paper proposes an approach to facilitate infrared small target detection by learning contrast-enhanced shape-biased representations. The approach cascades a contrast-shape encoder and a shape-reconstructable decoder to learn discriminative representations that can effectively identify target objects.

Effects of transgenerational photoperiod experience on the reproduction and development of , an egg parasitoid of the spotted lanternfly.

Transgenerational experience can affect a range of natural enemies' life-history traits and can be involved in the control of developmental plasticity. As a major egg parasitoid of the spotted lanternfly, (Hemiptera: Fulgoridae), the wasp (Hymenoptera: Eupelmidae) is effective at suppressing its host populations. The reproductive and developmental traits of is known to depend on photoperiod conditions, but transgenerational photoperiodic effects have yet to be evaluated.

Plasmonic Nanomaterials in Dark Field Sensing Systems.

Plasma nanoparticles offer promise in data storage, biosensing, optical imaging, photoelectric integration, etc. This review highlights the local surface plasmon resonance (LSPR) excitation mechanism of plasmonic nanoprobes and its critical significance in the control of dark-field sensing, as well as three main sensing strategies based on plasmonic nanomaterial dielectric environment modification, electromagnetic coupling, and charge transfer. This review then describes the component materials of plasmonic nanoprobes based on gold, silver, and other noble metals, as well as their applications.

Study on multi-objective decision-making operation strategy of heat supply tower.

In northern China, the long-term operation of ground source heat pumps brings the problem of soil cold accumulation, which can be effectively solved by adopting the heat supply tower to recharge the ground in summer. In this paper, seven indexes affecting the performance of the heat supply tower, such as temperature difference between inlet and outlet water, heating approach, thermal efficiency, and exergy destruction, are studied experimentally, and the energy efficiency ratio of the heat supply tower is analyzed. Then, based on the experimental data, the decision of the operating conditions is made.

Non-scientific classification of Chinese herbal medicine as dietary supplement.

This article focuses the category status of Chinese herbal medicine in the United States where it has been mistakenly classifified as a dietary supplement. According to Yellow Emperor Canon of Internal Medicine (Huang Di Nei Jing), clinical treatment in broad sense is to apply certain poisonous medicines to fight against pathogeneses, by which all medicines have certain toxicity and side effect. From ancient times to modern society, all, or at least most, practitioners have used herbal medicine to treat patients' medical conditions.
