The aim of work was to test the using of reamberin on patients with cerebral deficiency due to severe forms of acute poisonings. The investigation was made on 60 patients (38 men and 22 women), whose average age was 34.7 +/- 2.6 (for men) and 28.4 +/- 3.2 (for women). The main group was divided into two parts, which had compared age, sex and gravity of condition. The first one was given reamberin with standart therapy (I - 32 patients), the second - only standart therapy (II - 28 patients). It was revealed that using of reamberin in complex therapy of acute cerebral deficiency lead to decrease of intensity of cerebral deficiency and to increase of speed of cerebral activity rehabilitation. These changes lead to improvement of clinic tendency of cerebral deficiency, what was illustrated by decrease of comatose period from 55.0+/- 2.2 to 33.0 +/- 2.6 hours, decrease of the time of being in reanimatology department from 69.1+/- 3.6 to 53.4+/- 4.3 hours.

Background: Iduronate-2-sulfatase (IDS) deficiency (MPS II; Hunter syndrome) is a disorder that exhibits peripheral and CNS pathology. The blood brain barrier (BBB) prevents systemic enzyme replacement therapy (ERT) from alleviating CNS pathology. We aimed to enable brain delivery of systemic ERT by using molecular BBB-Trojans targeting endothelial transcytosis receptors.

The thrombolytic protease tissue plasminogen activator (tPA) is expressed in the CNS, where it regulates diverse functions including neuronal plasticity, neuroinflammation, and blood-brain-barrier integrity. However, its role in different brain regions such as the substantia nigra (SN) is largely unexplored. In this study, we characterize tPA expression, activity, and localization in the SN using a combination of retrograde tracing and β-galactosidase tPA reporter mice.

This case report provides details of the first documented case of pituitary stalk interruption syndrome (PSIS) with coexistent focal cortical dysplasia (FCD) in a young boy. The child's initial presentation was an afebrile, generalised tonic-clonic seizure associated with postictal drowsiness. During his first episode, the physical examination revealed a short, obese child with a micropenis and left cryptorchidism.

Alpha-1 antitrypsin (AAT) deficiency (AATD) is a monogenic disease caused by misfolding of AAT variants resulting in gain-of-toxic aggregation in the liver and loss of monomer activity in the lung leading to chronic obstructive pulmonary disease (COPD). Using high-throughput screening, we discovered a bioactive natural product, phenethyl isothiocyanate (PEITC), highly enriched in cruciferous vegetables, including watercress and broccoli, which improves the level of monomer secretion and neutrophil elastase (NE) inhibitory activity of AAT-Z through the endoplasmic reticulum (ER) redox sensor protein disulfide isomerase (PDI) A4 (PDIA4). The intracellular polymer burden of AAT-Z can be managed by combination treatment of PEITC and an autophagy activator.

Soluble guanylate cyclase (sGC) stands as a pivotal regulatory element in intracellular signalling pathways, mediating the formation of cyclic guanosine monophosphate (cGMP) and impacting diverse physiological processes across tissues. Increased formation of reactive oxygen species (ROS) is widely recognized to modulate cGMP signalling. Indeed, oxidatively damaged, and therefore inactive sGC, contributes to poor vascular reactivity and more severe neurological damage upon stroke.
