Shorter donor leukocyte telomere length is associated with poor peripheral blood stem cell mobilization induced by granulocyte colony-stimulating factor.

Background/purpose: Insufficient numbers of peripheral blood stem cells (PBSC) after granulocyte colony-stimulating factor (G-CSF) mobilization occurs in a significant proportion of PBSC collections, often from older age donors. Telomere length (TL) is often used as an indicator of an individual's biological age. This study aimed to investigate the relationship between donors' leukocyte TL and the outcome of G-CSF-induced PBSC mobilization in healthy unrelated donors.

Intra-Articular Lactate Dehydrogenase A Inhibitor Oxamate Reduces Experimental Osteoarthritis and Nociception in Rats via Possible Alteration of Glycolysis-Related Protein Expression in Cartilage Tissue.

Osteoarthritis (OA) is the most common form of arthritis and joint disorder worldwide. Metabolic reprogramming of osteoarthritic chondrocytes from oxidative phosphorylation to glycolysis results in the accumulation of lactate from glycolytic metabolite pyruvate by lactate dehydrogenase A (LDHA), leading to cartilage degeneration. In the present study, we investigated the protective effects of the intra-articular administration of oxamate (LDHA inhibitor) against OA development and glycolysis-related protein expression in experimental OA rats.

Isoaaptamine increases ROS levels causing autophagy and mitochondria-mediated apoptosis in glioblastoma multiforme cells.

Glioblastoma multiforme (GBM) is a common central nervous system disease with a poor prognosis; its five-year survival rate is <5 %, and its median survival of 15 months. Current treatment includes chemotherapy with temozolomide, which is ineffective against GBM, suggesting an urgent need to develop novel therapies. This study evaluated isoaaptamine and aaptamine in the GBM cell lines for cell viability; GBM 8401, U87 MG, U138 MG, and T98G.

Role of PVAT in obesity-related cardiovascular disease through the buffering activity of ATF3.

Thoracic aortic perivascular adipose tissue (PVAT) is an adipose organ exhibiting similarities to brown adipose tissue (BAT), including cellular morphology and thermogenic gene expression. However, whether the PVAT phenotype is indistinguishable from the BAT phenotype in physiological vasculature remains unclear. We demonstrated that PVAT is distinguishable from classical BAT, given its specific vessel-tone-controlling function.

Increased pro-inflammatory cytokines, C-reactive protein and nerve growth factor expressions in serum of patients with interstitial cystitis/bladder pain syndrome.

Objective: The etiology and pathogenesis of interstitial cystitis/bladder pain syndrome (IC/BPS) are unclear. Chronic inflammation is considered the main pathology of IC/BPS. This study measured the serum c-reactive protein (CRP), nerve growth factor (NGF) and pro-inflammatory cytokine/chemokine interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, and IL-8 expression in patients with IC/BPS to elucidate the involvement of systemic inflammation in IC/BPS.

Increased serum adipokines implicate chronic inflammation in the pathogenesis of overactive bladder syndrome refractory to antimuscarinic therapy.

Objectives: Recent studies have shown that chronic inflammation is involved in overactive bladder (OAB) syndrome. OAB could be a subtype of neurogenic inflammation. This pilot study investigated serum adipokine levels in patients with OAB refractory to antimuscarinic therapy.

Effect of alanine replacement of l17 and f19 on the aggregation and neurotoxicity of arctic-type aβ40.

Alzheimer's disease is the most common form of neurodegenerative disease. Beta-amyloid peptides (Aβ) are responsible for neuronal death both in vitro and in vivo. Previously, L17 and F19 residues were identified as playing key roles in the stabilization of the Aβ40 conformation and in the reduction of its neurotoxicity.

Increased urine and serum nerve growth factor levels in interstitial cystitis suggest chronic inflammation is involved in the pathogenesis of disease.

Objective: Interstitial cystitis/bladder pain syndrome (IC/BPS) is considered a bladder disorder due to localized chronic inflammation. This study investigated the nerve growth factor (NGF) levels in serum and urine in patients with IC/BPS.

Materials And Methods: Thirty patients with IC/BPS and 28 normal subjects without lower urinary tract symptoms were recruited from an outpatient clinic.

Immunohistochemical evidence suggests repeated intravesical application of botulinum toxin A injections may improve treatment efficacy of interstitial cystitis/bladder pain syndrome.

Unlabelled: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: A single set of botulinum toxin A (BoNT-A) injections relieves clinical symptoms of interstitial cystitis/bladder pain syndrome (IC/BPS), but lacks long-term effect. An inadequate anti-inflammatory effect is likely to cause treatment failure. The study shows that chronic inflammation and apoptotic signalling molecules are significantly reduced after repeated intravesical BoNT-A injection in patients with IC/BPS.
