Background: The levels of β-amyloid precursor protein (β-APP), tau protein, and phosphorylation of tau (p-tau) protein were examined by quantitative immunohistochemistry in the spinal cord sections of mice suffering from experimental autoimmune encephalomyelitis (EAE) in the successive phases of the disease: onset, peak, and chronic.

Methods: EAE was induced in C57BL/6 mice by immunization with MOG35-55 peptide. The degree of pathological changes was assessed in cross-sections of the entire spinal cord.

The circadian clock controls various physiological processes, including synaptic function and neuronal activity, affecting the functioning of the entire organism. Light is an important external factor regulating the day-night cycle. This study examined the effects of the circadian clock and light on synaptic plasticity, and explored how locomotor activity contributes to these processes.

The goal of this study was to evaluate the intensity of autophagy and ubiquitin-dependent proteolysis processes occurring in myocardium of left ventricle (LV) in subsequent stages of pulmonary arterial hypertension (PAH) to determine mechanisms responsible for LV mass loss in a monocrotaline-induced PAH rat model. LV myocardium samples collected from 32 Wistar rats were analyzed in an early PAH group (n = 8), controls time-paired (n = 8), an end-stage PAH group (n = 8), and their controls (n = 8). Samples were subjected to histological analyses with immunofluorescence staining, autophagy assessment by western blotting, and evaluation of ubiquitin-dependent proteolysis in the LV by immunoprecipitation of ubiquitinated proteins.

Article Synopsis
  • Boldenone (Bdn) and nandrolone (Ndn) are anabolic steroids that may pose a risk of cancer transformation in pig ovarian stem cells and can activate the NF-κB pathway.
  • The study aimed to determine if Bdn and Ndn activate the NF-κB pathway through the membrane androgen receptor ZIP-9 by analyzing gene expression and protein localization associated with this pathway.
  • Findings indicated an increase in certain phosphorylated proteins confirming NF-κB activation, but also suggested that ZIP-9 may not play a significant role in regulating this pathway due to reduced expression levels.

Morbihan syndrome (MS) is characterized by solid facial edema, usually related to rosacea or acne vulgaris. The facial edema deforms the patient's features, can impair peripheral vision, and affects quality of life. Its pathophysiology remains unclear.
