Summary: This study found that neutrophils in the neonatal brain are rapidly activated after experimental hypoxia-ischemia, producing reactive oxygen species and showing an increased proportion of hyperactivated/aged cells compared to peripheral neutrophils. Delayed neutrophil depletion led to reduced cellular neurodegeneration and decreased microglial and astroglial activation, offering new possibilities for therapeutic approaches in post-hypoxic brain injury.

Summary: Polyphenols, including resveratrol, have potential neuroprotective effects against neonatal hypoxia-ischemia-induced damage due to their anti-apoptotic, anti-inflammatory, and anti-oxidative properties, and may enhance brain energy metabolism. Maternal supplementation at nutritional doses shows promising results and could be a novel prophylactic treatment for neonatal hypoxia-ischemia.

Summary: Hypoxic-ischemic encephalopathy (HIE) is a major cause of morbidity and mortality in term neonates. Recent studies have shown that molecular hydrogen may have neuroprotective effects in combating the deleterious consequences of hypoxic-ischemic insults. However, further research is needed to explore the potential synergistic effect of hydrogen with therapeutic hypothermia for the treatment of HIE.

Summary: This study demonstrates that lactoferrin (Lf) supplementation attenuates acute and long-term cerebral injuries caused by hypoxia-ischemia in a dose-dependent manner. The optimal dose of 1 g/kg of Lf showed the best effects, reducing brain volume decreases and other detrimental effects. The research emphasizes the need for better understanding of Lf's effects and potential harmful effects on immature brains.

Summary: Neonatal hypoxia-ischemia (HI) can lead to a neurological condition called hypoxic-ischemic encephalopathy (HIE) in newborns, resulting in overall disability. The current treatment for affected neonates is therapeutic hypothermia, but it is not always effective in preventing the harmful effects of HI. Therefore, cannabinoids are being researched as potential new therapies. Modulating the endocannabinoid system (ECS) may reduce brain damage and stimulate cell proliferation. This study examined the middle- and long-term effects of 2-AG, the most abundant endocannabinoid, after neonatal HI in rats, and found that it reduced brain injury and promoted cell proliferation, suggesting long-lasting neuroprotective effects.

Summary: The study found that L-Cysteine treatment prevented acute brain damage and long-term memory impairment in neonatal mice exposed to hypoxia-ischemia. This protective effect was associated with the phosphorylation of Akt and PTEN. The neuroprotective effects of L-Cysteine were attenuated when the PI3K inhibitor, LY294002, was used.

Summary: Neonatal hypoxic-ischemic encephalopathy (HIE) is the leading cause of neonatal mortality and disability. Currently, hypothermia is the only approved treatment, but its therapeutic efficacy is limited. Therefore, there is a need to understand the molecular pathogenesis of HIE and develop novel therapies.

Summary: An attractive, versatile, and operationally simple visible-light-induced trifluoromethylation method has been demonstrated, which is transition-metal-free, photocatalyst-free, and oxidant-free. Inexpensive and readily available triflic anhydride (Tf2O) was chosen as the radical trifluoromethyl source, and thianthrene was used as a recyclable Tf2O-activating reagent, achieving a high-yielding and scalable trifluoromethylation reaction. Density functional theory and mechanistic studies revealed that the reaction involves a free radical homolytic process excited by visible light, generating a key trifluoromethyl radical intermediate.

Summary: Vitamin E has potential as a neuroprotectant in newborn infants with brain injury, but its effectiveness in clinical settings is still uncertain. Recent studies have shown that fat emulsions containing higher levels of Vitamin E can improve outcomes in neonatal co-morbidities, leading to a reconsideration of Vitamin E administration as a potential therapeutic modality. This review discusses the structure, mechanism(s) of action, evidence in animal models, and association with health outcomes in neonates, highlighting the need for further research and assessment of safety profiles before large clinical trials.

Summary: Clinical and experimental studies suggest sexual dimorphism in neonatal brain injury and therapy responses caused by hypoxia-ischemia (HI). This study found that regulatory T cells (Tregs) from neonatal female mice provide neuroprotection, while Tregs from male mice increase secondary neurodegeneration, which may be associated with intrinsic transcriptional differences between sexes. There is an urgent need for sex-stratified clinical and preclinical analyses.

Summary: This study explored the protective effects of magnesium hydride (MgH2) on two types of ARDS models and its underlying mechanism in a lipopolysaccharide (LPS)-induced ARDS model of the A549 cell line. Results showed that MgH2 exerted anti-inflammatory, antioxidant, anti-apoptotic, and barrier-protective effects by regulating molecular signaling pathways. The in vivo study also demonstrated that MgH2-treated mice had a better survival rate and less pathological damage.

Summary: This study analyzed the molecular composition of the medusa and polyp of Aurelia coerulea and compared its toxicity with another scyphozoan jellyfish, Stomolophus meleagris. The results showed that A. coerulea medusae and polyps have similar molecular compositions, but their gene expressions are significantly different. A. coerulea medusa displayed weaker toxicity compared to S. meleagris medusa, and the variation in toxin expressions may be an important factor contributing to the difference in toxicity.

Summary: In this study, different current modes were used to butt-weld 1460 Al-Li alloy plates. The effects of these current modes on the weld microstructure and mechanical properties were compared. The results showed that modulating pulsed current can refine the grains in the weld zone and fusion zone, and significantly increase the quantity and width of a fine strip-like equiaxed grain zone. Both P-VPTIG and DP-VPTIG processes effectively enhanced the strength and elongation of the joints.

Summary: The development of green technology allows manufacturers in traditional industries to reduce carbon emissions, but the adoption of this technology varies among manufacturers. By implementing an effective green technology licensing strategy, highly efficient manufacturers can share their technology with less efficient manufacturers. The government has introduced subsidies to promote the use of green technology among manufacturers. However, the effectiveness of these subsidies, especially in the face of intense market competition, is still uncertain. This study develops a game theory model to analyze the optimal subsidy policy for the government.

Summary: Sphingosine-1-phosphate (S1P) plays a role in the pathophysiology of neurological injury after aneurysmal subarachnoid haemorrhage (aSAH). The literature agrees that S1P increases in cerebrospinal fluid following aSAH and contributes to cerebral artery vasospasm. However, the role of S1P in the parenchyma is less clear, with conflicting studies suggesting both beneficial and harmful effects. This review provides a concise interpretation of the conflicting data and discusses the potential repurposing of S1P receptor modulators for aSAH.

Summary: Depression has a higher incidence in women compared to men, and this study investigated the impact of sex on depressive behaviors and underlying mechanisms using a corticosterone-induced depression model in mice. The results showed sex-specific anxiety and depression behaviors in the model group, as well as differences in protein expression and neurotransmitter levels between male and female mice. These findings enhance our understanding of sex-specific differences in depression and support tailored interventions.

Summary: This study explores the effects of prolonged mask usage on the human brain by analyzing EEG and physiological parameters. The results show that the mean EEG spectral power in alpha, beta, and gamma sub-bands of individuals wearing masks is smaller than those without masks. The performances on cognitive tasks and oxygen saturation level differ between the two groups, while blood pressure, body temperature, and heart rate are similar. The analysis also reveals that the occipital and frontal lobes exhibit the greatest variability in channel measurements.
