Inference from longitudinal laboratory tests characterizes temporal evolution of COVID-19-associated coagulopathy (CAC).

Temporal inference from laboratory testing results and triangulation with clinical outcomes extracted from unstructured electronic health record (EHR) provider notes is integral to advancing precision medicine. Here, we studied 246 SARS-CoV-2 PCR-positive (COVID) patients and propensity-matched 2460 SARS-CoV-2 PCR-negative (COVID) patients subjected to around 700,000 lab tests cumulatively across 194 assays. Compared to COVID patients at the time of diagnostic testing, COVID patients tended to have higher plasma fibrinogen levels and lower platelet counts.

In vitro binding affinities of a series of flavonoids for μ-opioid receptors. Antinociceptive effect of the synthetic flavonoid 3,3-dibromoflavanone in mice.

The pharmacotherapy for the treatment of pain is an active area of investigation. There are effective drugs to treat this problem, but there is also a need to find alternative treatments free of undesirable side effects. In the present work the capacity of a series of flavonoids to bind to the μ opioid receptor was evaluated.

Chronic intraperitoneal and oral treatments with hesperidin induce central nervous system effects in mice.

Hesperidin (HN) is a flavanone glycoside abundantly found in citrus fruits. This flavonoid mediated central nervous system activity following intraperitoneal (i.p.

Hesperidin induces antinociceptive effect in mice and its aglycone, hesperetin, binds to μ-opioid receptor and inhibits GIRK1/2 currents.

This paper extended the evaluation of the depressant and antinociceptive activities of hesperidin in order to determine its effectiveness by the intraperitoneal and oral routes, its pharmacological interaction with diverse pathways of neurotransmission and the role of its aglycone, hesperetin. The capacity of hesperidin and hesperetin to bind to μ-opioid receptor and their actions on μ-opioid receptor co-expressed with GIRK1/GIRK2 channels (G protein-activated inwardly rectifying K+ channels) in Xenopus laevis oocytes were also determined. Hesperidin exhibited a depressant activity in the hole board and locomotor activity tests, antinociceptive activities in the abdominal writhing and hot plate tests and no motor incoordination in the inverted screen and rotarod assays, only by the intraperitoneal route.

Neuroactive flavonoid glycosides from Tilia petiolaris DC. extracts.

Pharmacological assay guided purification of an ethanol extract of Tilia petiolaris DC. inflorescences resulted in the isolation and identification of isoquercitrin (ISO), quercetin 3-O-glucoside-7-O-rhamnoside (QUE) and kaempferol 3-O-glucoside-7-O-rhamnoside (KAE). The behavioral actions of these glycosylated flavonoids were examined in the hole board, locomotor activity and thiopental-induced loss of righting reflex tests in mice.
