Outcome of Ischemic Stroke at Six Months with Neuroglobin as a Marker.
Innov Clin Neurosci
December 2024
Drs. Ramli, Rusdi, Kurniawan, and Evelyn are with the Department of Neurology, Faculty of Medicine, Universitas Indonesia in Jakarta, Indonesia.
Prognostic markers can optimize the management of acute ischemic stroke (AIS). Neuroglobin (Ngb), which plays a role in intraneuronal oxygen transport and hypoxia resistance, is a potential prognostic marker in AIS. A cohort study was conducted on patients with AIS treated at Dr.

Prolyl hydroxylase domain 2 (PHD2) is the primary oxygen sensing enzyme involved in hydroxylation of hypoxia-inducible factor (HIF). Under normoxic conditions, PHD2 hydroxylates specific proline residues in HIF-1α and HIF-2α, promoting their ubiquitination and subsequent proteasomal degradation. Although PHD2 activity decreases in hypoxia, notable residual activity persists, but its function in these conditions remains unclear Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (Pin1) targets proteins with phosphorylated serine/threonine-proline (pSer/Thr-Pro) motifs.

Conventional practices for inorganic nitrogen fertilizer are highly inefficient leading to excess nitrogen in the environment. Excess environmental nitrogen induces ecological (, hypoxia, eutrophication) and public health (, nitrate contaminated drinking water) consequences, motivating adoption of management strategies to improve fertilizer use efficiency. Yet, how to limit the environmental impacts from inorganic nitrogen fertilizer while maintaining crop yields is a persistent challenge.

Assessing how at-risk species respond to co-occurring stressors is critical for predicting climate change vulnerability. In this study, we characterized how young-of-the-year White Sturgeon () cope with warming and low oxygen (hypoxia) and investigated whether prior exposure to one stressor may improve the tolerance to a subsequent stressor through "cross-tolerance". Fish were acclimated to five temperatures within their natural range (14-22°C) for one month prior to assessment of thermal tolerance (critical thermal maxima, CTmax) and hypoxia tolerance (incipient lethal oxygen saturation, ILOS; tested at 20°C).

Background: Newborns with transposition of the great arteries (TGA) are at risk of severe hypoxia from inadequate atrial mixing, closure of the arterial duct and/or pulmonary hypertension (PPHN). Acute maternal hyperoxygenation (AMH) might assist in identifying at-risk fetuses. We report pulmonary vasoreactivity to AMH in TGA fetuses and its relationship to early postnatal hypoxia and requirement for emergency balloon atrial septostomy (e-BAS).
