Summary: This study proposed a new design strategy based on pi-conjugation modulation for fluorescent probes, which can generate different emission bands in the presence and absence of the target. The newly designed fluorescence probe, Rhod-DCM-B, exhibited outstanding sensitivity and excellent selectivity towards ONOO-. It was successfully employed to determine endogenous and exogenous ONOO- in living cells, and effectively monitored the ONOO- in vivo.

Summary: This study investigates the effects of Pulsed Electric Fields and High-Pressure pre-treatments on the osmotic dehydration of fresh-cut cherry tomatoes. The results show that a 100-pulse PEF treatment and HP treatment at 600 MPa achieve optimal outcomes in terms of OD enhancement and product acceptability, while also extending the shelf life.

Summary: The results of the study indicate that 10 weeks of social isolation led to a significant decrease in PPI, accompanied by a decrease in NOS activity in the cerebral cortex and the cerebellum, an increase in iNOS in the hippocampus, and an increase in CD concentration in cortex homogenate. On the other hand, 29 weeks of social isolation had an opposite effect on NOS activity, with an increase in the cerebral cortex and the cerebellum in animals reared in a social environment, accompanied by a decrease in CD concentration.

Summary: A meta-analysis of 86 studies has shown that nitric oxide (NO) can significantly improve plant biomass, alleviate oxidative damage, and increase the content of Ca, Fe, and Mg in heavy metal-stressed plants. The optimal concentration of SNP (an NO donor) for hydroponic culture is in the range of 75-150 μM. These findings provide valuable insights for the future application of NO as a plant growth regulator for enhancing heavy metal stress tolerance in agriculture and breeding.

Summary: Cardiovascular disease is the leading cause of global death, with endothelial dysfunction being a predictor for most CVD. Polyphenols from sources like wine and grape extracts can help prevent endothelial dysfunction, while anthocyanin flavonoids found in berries also improve vascular function.

Summary: Sewage water (SW) causes heavy metal accumulation in soil, particularly lead contamination, which affects plant growth and produce quality. Pot experiments were conducted to study the effects of zeolite soil amendment on tomato plants grown with SW irrigation. Results showed that the application of 0.75% zeolite improved plant growth attributes and decreased lead accumulation compared to SW-irrigated plants. Zeolite treatment also increased chlorophyll content and physiological traits in the plants. This study highlights the potential of zeolite as a soil amendment to mitigate the negative effects of SW irrigation on crop growth and metal accumulation.

Summary: Fruit formation is dependent on successful fertilization and is susceptible to weather fluctuations affecting pollination. The auxin hormone plays a role in fruit initiation and growth after fertilization. This study examines the regulation of fruit set and growth by the ARF family in tomato and Arabidopsis, and demonstrates that reducing the activity of SlARF8 genes can improve yield stability in fluctuating temperatures.

Summary: Nitric oxide (NO) is a crucial signaling molecule in plants, playing roles in regulating plant growth and development, and responding to stress. Cadmium (Cd) pollution is a widespread environmental hazard that inhibits plant growth and threatens human health. Plants have evolved mechanisms to cope with Cd stress, and NO is known to be involved in these responses. However, the mechanisms by which Cd stress affects the accumulation of endogenous NO in plants and the role of exogenous NO in plant responses to Cd stress remain unclear.

Summary: Nitrite concentrations in blood play a crucial role in assessing intracellular nitric oxide (NO) activity and endothelial function. However, using nitrosylhemoglobin (HbNO) as an early marker of COVID-19 patient risk may be premature.

Summary: Mitochondria play critical roles in neurons by regulating neurotransmission and synaptic plasticity through ATP supply, calcium homeostasis, redox balance control, and apoptosis. Their functional integrity is mainly maintained by mitostasis, involving processes like mitochondrial transport, anchoring, fusion, and fission, regulated by various signaling pathways. The communication between mitochondria and the endoplasmic reticulum (ER) via mitochondria-associated membranes (MAMs) is crucial for Ca2+ buffering. Alterations in mitochondrial activity can lead to increased production of reactive oxygen species, disturbance in physiological metabolism, and mitochondrial dysfunction resulting in cell death through apoptosis.
