A Dynamic Interference Detection Method of Underwater Scenes Based on Deep Learning and Attention Mechanism.

Improving the three-dimensional reconstruction of underwater scenes is a challenging and hot topic in the field of underwater robot vision system research. High dynamic interference underwater has always been one of the key issues affecting the 3D reconstruction of underwater scenes. However, due to the complex underwater environment and insufficient light, existing target detection algorithms cannot meet the requirements.

Effectiveness of low-load resistance training with blood flow restriction vs. conventional high-intensity resistance training in older people diagnosed with sarcopenia: a randomized controlled trial.

Low-load resistance training with blood flow restriction (LRT-BFR) has shown potential to improve muscle strength and mass in different populations; however, there remains limited evidence in sarcopenic people diagnosed with sarcopenia criteria. This study systematically compared the effectiveness of LRT-BFR and conventional high-intensity resistance training (CRT) on clinical muscle outcomes (muscle mass, strength and performance), cardiovascular disease (CVD) risk factors and sarcopenia-related biomarkers of older people with sarcopenia. Twenty-one older individuals (aged 65 years and older) diagnosed with sarcopenia were randomly assigned to the LRT-BFR (20%-30% one-repetition maximum (1RM), n = 10) or CRT (60%-70% 1RM, n = 11) group.

Perceived protective behavioral changes in Chinese residents post-dynamic zero-COVID policy lifting: a cross-sectional study.

Objective: To investigate how Chinese residents perceived changes in their protective behaviors in the early stage after the lifting of the dynamic zero-COVID policy, and to explore the associations between the overall perceived change and factors such as demographic and health-related information, COVID-19 related perceptions, negative emotions, and coping styles.

Methods: This cross-sectional study involved 798 Chinese residents who completed an online questionnaire between 16 and 25 December 2022. The questionnaire covered demographic and health-related information, COVID-19 related perceptions, negative emotions, coping styles, and perceived changes in protective behaviors.

Development and preliminary assessment of the iFIND TBR: all-in- one molecular diagnostic assay for rapid detection of and rifampicin resistance.

In this study, we introduced the iFIND TBR assay, an automated all-in-one tuberculosis detection approach that simultaneously detect (MTB) and rifampicin (RIF) resistance.

Methods: The limits of detection (LOD), sensitivity, specificity, and RIF-R rpoB mutation detection of the iFIND TBR were tested on Mycobacterium tuberculosis DNA or sputum samples spiked with known numbers of M.

Bioadhesive First-Aid Patch with Rapid Hemostasis and High Toughness Designed for Sutureless Sealing of Acute Bleeding Wounds.

The global military and civilian sectors express widespread concern over the significant hemorrhage associated with various acute wounds. Such bleedings lead to numerous casualties in military confrontations, traffic accidents, and surgical injuries. Consequently, the rapid control of the bleedings, particularly for extensive and pressurized wounds, is crucial in first-aid situations.

Chronic Real-Ambient PM Exposure Exacerbates Cardiovascular Risk via Amplifying Liver Injury in Mice Fed with a High-Fat and High-Cholesterol Diet.

Epidemiology has associated fine particulate matter (PM) exposure with an increased cardiovascular risk. However, the underlying mechanism, particularly from the liver perspective, remains unclear. Here, the influence of chronic PM exposure on cardiovascular risk in mice fed a high-fat and high-cholesterol diet (HFCD) was studied by using a real-world PM exposure system.

RHBDF1 promotes PERK expression through the JNK/FoxO3 pathway in breast cancer cells.

Human rhomboid family-1 ( ) gene is recognized as an oncogene involved in breast cancer development. Previous studies have indicated that RHBDF1 contributes significantly to endoplasmic reticulum (ER) protein homeostasis by stabilizing the binding immunoglobulin protein (BiP) and promoting the unfolded protein response (UPR). Here, we report a relationship between RHBDF1 and the ER stress sensors PERK, IRE1, and ATF6.

OsCNGC7 modulates calcium dynamics and accelerates leaf senescence in rice.

Calcium plays a crucial role in regulating plant senescence. However, the specific effects of increased intranuclear calcium versus cytoplasmic calcium on aging remain unclear. Cyclic nucleotide-gated channels (CNGCs), which manage Ca⁺ levels in plant cells, are particularly significant in this context.

Synergistic interaction between brassinosteroid and jasmonate pathways in rice response to cadmium toxicity.

Brassinosteroids (BRs) and jasmonic acid (JA) are known to be involved in regulating plant responses to cadmium (Cd) stress. However, their specific roles and interaction in this process remain unclear. In this study, we discovered that exogenous BR alleviated Cd-mediated growth inhibition of rice seedlings.

The corncobs-loaded iron nanoparticles enhanced mechanism of denitrification performance in microalgal-bacterial aggregates system when treating low COD/TN wastewater.

To improve denitrification efficiency of microalgal-bacterial aggregates (MABAs) when treating low carbon to nitrogen (C/N) ratio wastewater, CK (the biological control), C1 (untreated corncobs), C2 (alkali-treated corncobs), CFe1 (C1 loaded iron nanoparticles) and CFe2 (C2 loaded iron nanoparticles) five groups of experiments were installed under artificial light (1600 lm). After 36 h of experiment, NO-N was almost completely converted in CFe1 following by CFe2 when the initial concentration was 60.1 mg/L, whose NO-N conversion rates were 6.

Study on Active Components and Mechanism of Lettuce Latex Against Spodoptera Litura.

Plant latex is a sticky emulsion exuded from laticifers once the plant is damaged. Latex is an essential component of plant defense against herbivores. Lettuce (Lactuca sativa L.

Nontarget Analysis of Legacy and Emerging PFAS in a Lithium-Ion Power Battery Recycling Park and Their Possible Toxicity Measured Using High-Throughput Phenotype Screening.

Driven by the global popularity of electric vehicles and the shortage of critical raw materials for batteries, the spent lithium-ion power battery (LIPB) recycling industry has exhibited explosive growth in both quantity and scale. However, relatively little information is known about the environmental risks posed by LIPB recycling, in particular with regards to perfluoroalkyl and polyfluoroalkyl substances (PFAS). In this work, suspect screening and nontarget analysis were carried out to characterize PFAS in soil, dust, water and sediment from a LIPB recycling area.

Experimental Study on the Effects of Carbonated Steel Slag Fine Aggregate on the Expansion Rate, Mechanical Properties and Carbonation Depth of Mortar.

Steel slag is the main by-product of the steel industry and can be used to produce steel slag fine aggregate (SSFA). SSFA can be used as a fine aggregate in mortar or concrete. However, SSFA contains f-CaO, which is the main reason for the expansion damage of mortar and concrete.

Metabolomic Profiling Reveals the Anti-Herbivore Mechanisms of Rice ().

The use of secondary metabolites of rice to control pests has become a research hotspot, but little is known about the mechanism of rice self-resistance. In this study, metabolomics analysis was performed on two groups of rice (T1, with insect pests; T2, without pests), indicating that fatty acids, alkaloids, and phenolic acids were significantly up-regulated in T1. The up-regulated metabolites (-value < 0.
