Furthermore, pharmacokinetics data of BBH in Crucian carp revealed its rapid absorption (Tmax of 1.5 h), suitable plasma half-life (t1/2z/h of 7-12 h depending on oral dosage), and dose-dependent drug exposure properties following oral administration (revealed by AUC0-t values). These findings shed light on repurposing BBH to treat CyHV-2 infections in silver crucian carp.Tmprss2 is an emerging molecular target which guides cellular infections of SARS-CoV-2, has been earmarked for interventions against the viral pathologies. The study aims to computationally screen and identifies potential miRNAs, following in vitro experimental validation of miRNA-mediated suppression of Tmprss2 for early prevention of COVID-19. Pool of 163 miRNAs, scrutinized for Tmprss2 binding with three miRNA prediction algorithms, ensued 11 common miRNAs. Further, computational negative energies for association, corroborated miRNA-Tmprss2 interactions, whereas three miRNAs (hsa-miR-214, hsa-miR-98 and hsa-miR-32) based on probability scores ≥0.8 and accessibility to Tmprss2 target have been selected in the Sfold tool. Transfection of miRNA(s) in the Caco-2 cells, quantitatively estimated differential expression, confirming silencing of Tmprss2 with maximum gene suppression by hsa-miR-32 employing novel promising role in CoV-2 pathogenesis. The exalted binding of miRNAs to Tmprss2 and suppression of later advocates their utility as molecular tools for prevention of SARS-CoV-2 viral transmission and replication in humans.During spinal cord injury (SCI), a quick and sustained decline of Neuregulin-1 (Nrg1) has been observed, exerting a significant positive effect in modulating the proliferation of astrocytes and the formation of glial scars within the damaged spinal cord. In this study, we revealed the abnormal downregulation of lncRNA Ftx and Nrg1 and upregulation of miR-382-5p after SCI, which contributed to the inflammatory response in microglial cells and affected SCI repair. Ftx overexpression was significantly reduced, and Ftx knockdown further promoted LPS effects on the inflammatory factors, indicating that lncRNA Ftx might affect the microglial inflammatory response. miR-382-5p targeted both lncRNA Ftx and Nrg1, and lncRNA Ftx competed with Nrg1 for miR-382-5p binding to act as a ceRNA, therefore counteracting miR-382-5p-mediated inhibition of Nrg1. miR-382-5p overexpression was significantly enhanced, and Nrg1 overexpression attenuated LPS effects on inflammatory factors within the microglia. Under LPS stimulation, the effects of Ftx overexpression were significantly reversed by overexpression of miR-382-5p, and the effects of miR-382-5p overexpression were significantly reversed by Nrg1 overexpression. In summary, the lncRNA Ftx/miR-382-5p/Nrg1 axis improves the inflammation response of the microglia, which might improve SCI repair.Sleep has an essential role for optimal brain function, but the cellular substrates for sleep regulation are not fully understood. Microglia, the immune cells of the brain, have gained increasingly more attention over the last two decades for their important roles in various brain functions that extend beyond their well-known immune function, including brain development, neuronal protection, and synaptic plasticity. Here we review recent advances in understanding i) morphological and phenotypic dynamics of microglia including process motility/growth and gene/protein expression, and ii) microglia-neuron interactions including phagocytosis and contact at synapses which alters neuronal circuit activity, both under physiological state in the adult brain. We discuss how the microglia-neuron interactions particularly at synapses could influence microglia and neuronal activities across circadian cycles and sleep/wake states. We also review recent findings on how microglia respond to sleep loss. We conclude by pointing out key questions and proposing suggestions for future research to better understand the role of microglia in sleep regulation, sleep homeostasis, and the function of sleep.

Cannabis sativa L. is an aromatic annual herb belonging to the family Cannabaceae and it is widely distributed worldwide. Cultivation, selling, and consumption of cannabis and cannabis related products, regardless of its use, was prohibited in Lebanon until April 22, 2020. Nevertheless, cannabis oil has been traditionally used unlawfully for many years in Lebanon to treat diseases such as arthritis, diabetes, cancer and few neurological disorders.

The present study aims to evaluate the phytochemical and anti-inflammatory properties of a cannabis oil preparation that is analogous to the illegally used cannabis oil in Lebanon.

Dried Cannabis flowers were extracted with ethanol without any purification procedures to simulate the extracts sold by underground dealers in Lebanon. GC/MS was performed to identify chemical components of the cannabis oil extract (COE). selleckchem In vivo anti-inflammatory effect of COE was evaluated by using carageenan- and formalin-induced paw edema rat models. TNF-α production were determ findings demonstrate that COE possesses remarkable in vivo and in vitro anti-inflammatory activities which support the traditional use of the Lebanese cannabis oil extract in the treatment of various inflammatory diseases including arthritis.

The current findings demonstrate that COE possesses remarkable in vivo and in vitro anti-inflammatory activities which support the traditional use of the Lebanese cannabis oil extract in the treatment of various inflammatory diseases including arthritis.

Viburnum taitoense Hayata has been used as folk medicine by the minority people in Southwestern China for a long history, especially in Guangxi Zhuang Autonomous Region. The minority in Guangxi including Zhuang, Miao and Yao people use the ethanol extract of V. taitoense Hayata to treat the fracture, kill the pain of rheumatism because of its definite therapeutic effects.

So far, the scientific investigation of V. taitoense Hayata is done very little. Here, we first prepared the ethyl acetate extract of V. taitoense (EEVt), secondly measured the contents of phenols, flavonoids, and terpenoids in EEVt, and thirdly, the anti-inflammatory and analgesic activities of EEVt were investigated by invitro model of RAW 264.7cells and invivo models of inflammation and pain in rats and mice.

The contents of phenols, flavonoids, and terpenoids in EEVt were determined by UV spectrophotometry, respectively. The anti-inflammatory effect of EEVt (5, 25, 50, 100, and 200μg/mL) in vitro was tested by determining its inhibitory effect on the nitric oxide production of RAW264.
