Summary: The study demonstrates that hypoxia significantly decreases aromatase activity in the brain of Atlantic croaker, with neuronal nitric oxide synthase activity and antioxidant status influencing this process. The results suggest that competitive NOS-inhibitors and powerful antioxidants can restore aromatase levels in vertebrate brains during hypoxic stress.

Summary: The Alaska blackfish is the only air-breathing fish in the Arctic. It can extract oxygen from the air in the summer, but not in the winter due to ice and snow cover. However, the blackfish remains active in winter despite the lack of oxygen and near freezing temperatures. The study suggests that cold acclimation suppresses reactive oxygen species production in the brain of Alaska blackfish, which may protect them from oxidative stress during winter when oxygen is limited.

Summary: This study aims to determine the transcriptional effect of tryptophan and cortisol on primary cell cultures of salmon head and posterior kidney. Results indicate activation of the kynurenine pathway and serotonin activity when stimulated with tryptophan and cortisol. Understanding the activation pathway and its relationship with stress levels associated with fish culture is essential for reducing economic losses.

Summary: This study investigates the developmental impact of acute prenatal hypoxia (APH) on the fetus and its relationship with sex and gestational age. The results show that APH has different effects on behavior and brain biochemistry depending on sex and gestational age, while the effects on ECG depend on gestational age rather than sex.

Summary: Over the past 30 years, rapid development of electronic information technology has led to the widespread use of electromagnetic-based technical achievements in various fields of human production and life, resulting in electromagnetic radiation (EMR) becoming a significant new source of pollution in modern civilization. The biological effects of EMR, particularly its interactions with human organs, especially the brain, have garnered significant attention worldwide. Recent studies have increasingly focused on the neurobiological effects of EMR, particularly in the metabolism and receptors of neurotransmitters in the brain.

Summary: Estrogens play an important role in the female reproductive system and also regulate physiological processes associated with learning and memory in the brain. They have neuroprotective effects in the pathogenesis of Alzheimer's disease (AD), which has a higher incidence in older and postmenopausal women. Estrogens bind to estrogen receptors (ERs) and activate transcriptional machineries, and also stimulate signal transduction through membrane ERs (mERs). Estrogen-related receptors (ERRs), which lack estrogen-binding capabilities, are expressed in the human brain and implicated in AD pathogenesis.

Summary: The presence of estrogen receptor beta (ER beta) is inversely correlated with the occurrence of colorectal cancer (CRC), and low expression of ER beta is associated with poorer overall survival of CRC patients. ER beta can inhibit tumorigenesis through various molecular pathways and also has an impact on the hypoxic response in CRC cells.

Summary: Recent studies have shown that hypoxia affects sex differentiation and reproductive function in fish, leading to a male-biased population. The molecular mechanisms through which hypoxia alters fish sex differentiation and sex ratios are still poorly understood. In this study, we conducted sequencing of small RNAs and transcripts in marine medaka embryos exposed to hypoxia, and identified dysregulated miRNAs and mRNAs. Our findings suggest that miRNA-mRNA interactions may play a role in regulating embryonic development and sex determination in response to hypoxic stress.

Summary: The study reveals overlapping expression of conserved transcription factors that specify the telencephalon in vertebrates in the chordate amphioxus. Specific co-expression is observed in the dorsal part of the anterior brain vesicle, referred to as Pars anterodorsalis (PAD). This suggests homology between the adult amphioxus brain vesicle PAD and the vertebrate telencephalon.

Summary: The study found that absolute values of NFL in blood, as well as early changes in NFL, can predict outcomes and differentiate severe sHIBI from other causes of poor outcome after OHCA with high sensitivity (100%) and specificity (91.7%). These findings suggest that NFL measured in blood should be incorporated into prognostication algorithms used in clinical practice.

Summary: In this study, an optical trapping Raman spectroscopic system was developed to quantitatively evaluate the concentration of small objects. Using artificial liposomes that mimic synaptic vesicles, it was found that the optical trapping of vesicles and the detection of spontaneous Raman scattered light can be achieved. The number of glutamate molecules in the trapped liposomes was estimated using a calibration curve, allowing for the measurement of glutamate molecules encapsulated in synaptic vesicles in situ.

Summary: The researchers developed a small molecular fluorescent probe that can specifically respond to norepinephrine (NE) on a 100-ms timescale, providing high spatiotemporal resolution for monitoring NE dynamics in living systems. The probe utilizes a dual acceleration mechanism of molecular-folding and water-bridging to enhance reaction kinetics. It successfully captured the fast fluctuation of NE levels at neuronal cytomembranes within 2s and revealed a correlation between downregulated NE levels and Alzheimer's disease pathology and antioxidant therapy through two-photon fluorescence imaging of acute brain tissue slices.

Summary: The growing popularity of online news has raised concerns about the socio-political influence on news dissemination, decreasing freedom of news media, and an easy news evaluation process. To address these challenges, this paper proposes a blockchain, smart contract, and incremental machine learning-based news evaluation procedure for the Bengali language. A weighted synthesis of machine classification and human expert opinion on a decentralized platform is used to evaluate news. The Natural Language Processing (NLP) model is incrementally trained with continuous data to detect unreliable fake news. Experimental results show an increase in accuracy from 84.94% and 84.99% to 93.75% and 93.80% after nine rounds of incremental model training. The protocols have been successfully implemented and tested on the Ethereum test network.

Summary: This study investigated the role of estrogen receptors (ERs) in vitellogenesis (Vtgs) regulation in pompano fish. The findings suggest that E2 may regulate the expression of different subtypes of vtg through ERs, displaying a compensatory expression effect on the regulation of ers and vtgs. This provides a theoretical basis for further research on reproductive endocrinology in pompano fish.

Summary: Endocrine changes during bird reproduction, particularly the relationship between prolactin and incubation behavior, were investigated. The study monitored the physiological status and incubation behavior of Silkie hens over 1-2 years. The results showed that most mature hens exhibited incubation behavior multiple times, and there was a noticeable increase in nest occupancy 7-10 days before incubation onset. Protein analysis revealed that secreted prolactin during the reproductive cycle contains various isoforms, suggesting post-translational modifications like glycosylation and phosphorylation.

Summary: The COVID-19 pandemic had a significant impact on academics, particularly on those with minoritized identities or who were early career, caregivers, or had intersecting identities. The pandemic altered the impact factors of academia, including scholarly products, and affected the way individuals could respond. It is predicted that the pandemic will have long-term impacts on the population dynamics, composition, and landscape of the academic ecosystem. The number of journal submissions decreased, especially among women authors, and the pandemic heavily impacted women authors from Asia and the Middle East.
