Infrared image target detection for substation electrical equipment based on improved faster region-based convolutional neural network algorithm.

Substation electrical equipment generates a massive number of infrared images during operation. However, the overall quality of the infrared images is low and it lacks image detail information. When using traditional target detection algorithms for detection, feature extraction poses great difficulties.

Specneuzhenide improves bleomycin-induced pulmonary fibrosis in mice via AMPK-dependent reduction of PD-L1.

Background: Pulmonary fibrosis (PF) is an escalating global health issue, characterized by rising rates of morbidity and mortality annually. Consequently, further investigation of potential damage mechanisms and potential preventive strategies for PF are warranted. Specnuezhenide (SPN), a prominent secoiridoid compound derived from Ligustrum lucidum Ait, exhibits anti-inflammatory and anti-oxidative capacities, indicating the potential therapeutic actions on PF.

Cerebral neurotoxicity of amino-modified polystyrene nanoplastics in mice and the protective effects of functional food Camellia pollen.

Accumulating evidence suggests that nanoplastics contribute to an increased risk of brain damage, however, the precise underlying mechanisms remain unclear. Here, we subjected mice to long-term exposure to amino-modified polystyrene nanoplastics (APS-NPs). These nanoplastics were detected in the mouse brain; coupled with the observed upregulation of Alzheimer's disease-associated genes (APP and MAPT).

Investigation of pulmonary toxicity evaluation on mice exposed to polystyrene nanoplastics: The potential protective role of the antioxidant N-acetylcysteine.

Accumulating evidences show that the hazardous substance atmospheric nanoplastics increase the respiratory risk of individuals, but the inside toxicity mechanisms to lung tissue remain unclear. This study aims at investigating the potential mechanisms of inhaled cationic polystyrene nanoplastics (amine-polystyrene nanoplastics, APS-NPs)-induced pulmonary toxicity on mice. In vivo, the mice intratracheal administrated with APS-NPs suspension (5 mg/kg) were found inflammatory infiltrates in lung tissues through histopathology analysis.

Protective effects of heterophyllin B against bleomycin-induced pulmonary fibrosis in mice via AMPK activation.

Pulmonary fibrosis (PF) is a chronic interstitial lung disease with unknown etiology. In the present study, we evaluated the anti-fibrotic effects of heterophyllin B, a natural product from Radix Pseudostellariae having anti-inflammatory and tyrosinase inhibitory activities. In bleomycin (BLM)-induced PF mouse model, heterophyllin B treatments (5 or 20 mg/kg/d) significantly attenuated BLM-induced alveolar cavity collapse, inflammatory cell infiltration, alveolar wall thickening and collagen deposition.

Exposure to PM during pregnancy causes lung inflammation in the offspring: Mechanism of action of mogrosides.

Epidemiological and toxicological studies have demonstrated that exposure to fine particulate matter (PM) during pregnancy is harmful to the tissues of the offspring. However, the mechanism by which PM exposure causes lung damage in the offspring or potential dietary therapy for this condition remains unclear. Mogrosides (MGs) are derived from the traditional plant Siraitia grosvenorii and are used medicinally, where they can moisten the lungs and relieve coughing.

Renoprotective activity of Ribes diacanthum pall (RDP) against inflammation in cisplatin-stimulated mice model and human renal tubular epithelial cells.

Ethnopharmacological Relevance: Ribes diacanthum Pall (RDP) is mostly distributed in Mongolia. As a Mongolian folk medicinal plant, it is traditionally used to treat kidney diseases by the native inhabitants of Mongolia due to its effect of increasing urine output and eliminating edema. However, its renal protection mechanism remains to be elucidated.

Activation of TRPC6 channels contributes to (+)-conocarpan-induced apoptotic cell death in HK-2 cells.

(+)-Conocarpan (CNCP), a neolignan frequently found in many medicinal and edible plants displays a broad spectrum of bioactivity. Here, we demonstrated that CNCP induced apoptotic cell death in human kidney-2 (HK-2) cells in a concentration-dependent manner (IC = 19.3 μM) and led to the sustained elevation of intracellular Ca ([Ca]).

Removal of heavy metals from aqueous solution by lipopeptides and lipopeptides modified Na-montmorillonite.

The removal of Cu(2+), Zn(2+), Cd(2+), Pb(2+) and Hg(2+) from aqueous solution by lipopeptides produced from solid-state fermentation (LPSSF) and LPSSF modified Na-montmorillonite clays (LPSSF/Na-MMT) was investigated. The results showed that the LPSSF had certain adsorption capability for the metal ions and the modification of Na-MMT with LPSSF at a weight ratio of 1:50 (LPSSF:Na-MMT) had the best adsorption capacity and adsorption rate. The adsorption of heavy metal ion on these adsorbents was monolayer sorption.

Comparative study on the properties of lipopeptide products and expression of biosynthetic genes from Bacillus amyloliquefaciens XZ-173 in liquid fermentation and solid-state fermentation.

This study compared the compositions and properties of lipopeptide products purified from liquid fermentation (LF) and solid-state fermentation (SSF) and transcription levels involved in lipopeptides under the two systems. Results of Fourier transform infrared spectroscopy and High performance liquid chromatography revealed no significant differences in the polarity and structure of the two lipopeptide products. A higher amino acid proportion was found for lipopeptide product in LF than in SSF.
