Neurological status was assessed and the numbers of neurons per 1 mm in pyramidal neuronal layer length in CA1 and CA4 hippocampal fields and cerebellar Purkinje cells were evaluated in albino male rats on post-resuscitation day 14 after 12-min cardiac arrest. Intraperitoneal administration of GK-2 (1 mg/kg 30 min after resuscitation and within the next 3 days with an interval of 24 h) accelerated neurological recovery of the animals, sharply reduced the intensity of cerebellar Purkinje cell death, and prevented loss of pyramidal neurons in the hippocampus. These results show the effectiveness of systemic administration of the nerve growth factor mimetic GK-2 in improving structural and functional state of the brain in the post-resuscitation period. This opens new prospects of its use for prevention and correction of post-hypoxic encephalopathy.

Stereocaulon alpinum has been found to have potential pharmaceutical properties due to the presence of secondary metabolites such as usnic acid, atranorin, and lobaric acid (LA) which have anticancer activity. On the other hand, the effect of LA on the stemness potential of colorectal cancer (CRC) cells remains unexplored, and has not yet been thoroughly investigated. In this study, we examined the inhibitory activity of LA from Stereocaulon alpinum against the stemness potential of CRC cells and investigated the possible underlying mechanisms.

Purpose: Spinal cord stimulation (SCS) is pivotal in treating chronic intractable pain. To elucidate the mechanism of action among conventional and current novel types of SCSs, a stable and reliable electrophysiology model in the consensus animals to mimic human SCS treatment is essential. We have recently developed a new in vivo implantable pulsed-ultrahigh-frequency (pUHF) SCS platform for conducting behavioral and electrophysiological studies in rats.

Neuroregulation during skin wound healing involves complex interactions between the nervous system and intricate tissue repair processes. The skin, the largest organ, depends on a complex system of nerves to manage responses to injury. Recent research has emphasized the crucial role of neuroregulation in maximizing wound healing outcomes.

Introduction: Endolymphatic sac tumor (ELST) is a rare neoplasm that exhibits aggressive growth primarily in the endolymphatic capsule and can potentially affect nearby neurovascular structures. The diagnosis of ELST poses challenges due to its low prevalence, gradual progression, and nonspecific symptomatology. It is currently believed that prompt surgical intervention is recommended for endolymphatic sac tumors upon diagnosis.
