Metaproteomic Experience Into the Microbial Neighborhood inside Pozol.
This brief review provides a comprehensive summary on the main sources of free radical damage, occurring in the setting of neurodegeneration.Biliverdin reductase-A (BVR) catalyzes the reduction of heme-derived biliverdin into bilirubin, this latter being a powerful endogenous free radical scavenger. Furthermore, BVR is also endowed with both serine/threonine/tyrosine kinase and scaffold activities, through which it interacts with the insulin receptor kinase, conventional and atypical protein kinase C isoforms, mitogen-activated protein kinases as well as the phosphatidylinositol-3 kinase/Akt system. By regulating this complex array of signal transduction pathways, BVR is involved in the pathogenesis of neurodegenerative, metabolic, cardiovascular and immune-inflammatory diseases as well as in cancer. In addition, both BVR and BVR-B, this latter being an alternate isozyme predominant during fetal development but sometimes detectable through adulthood, have been studied as peripheral biomarkers for an early detection of Alzheimer's disease, atherosclerosis and some types of cancer. However, despite these interesting lines of evidence, to date BVR has not been considered as an appealing drug target. Only limited evidence supports the neuroprotective effects of atorvastatin and ferulic acid through BVR regulation in the aged canine brain and human neuroblastoma cells, whereas interesting results have been reported regarding the use of BVR-based peptides in preclinical models of cardiac diseases and cancer.Airway epithelial mitochondrial oxidative stress and damage is an important pathology in chronic obstructive pulmonary disease (COPD). Mitophagy involves MAPK15-ULK1 signaling, the role of which is unknown in COPD. This study investigated MAPK15-ULK1 signaling in airway epithelial cells of COPD patients and its activation by cigarette smoke extract (CSE) in isolated human airway epithelial cells. Significant increased phosphorylation of MAPK15 and ULK1 (Ser555) was detected in the airway epithelium of COPD patients. This pathology was maintained in isolated primary COPD-epithelial cells. Compared to control cells, the protein expression of Beclin1 and the ratio of LC3II to LC3I were both significantly increased in COPD-epithelial cells. In human airway epithelial cells, CSE significantly increased the phosphorylation of MAPK15, ULK1 (Ser555), the expression of Beclin1, and the LC3II/LC3I ratio in a concentration- and time-dependent manner. Transfection with MAPK15 siRNA significantly inhibited the CSE-induced ULK1 (Ser555) phosphorylation in airway epithelial cells. Silencing of MAPK15 or ULK1 significantly reduced CSE-induced mitophagy and mitochondrial oxidative stress, thereby improving cell viability. In summary, cigarette smoke activated MAPK15-ULK1 signaling, thereby promoting mitophagy and mitochondrial oxidative stress in airway epithelial cells. This signaling pathway is activated in COPD-epithelial cells and therefore might present a novel therapeutic target for COPD.
Benign prostatic hyperplasia (BPH) is the hyperproliferation of the stromal and the epithelial cells within the prostatic transition zone. In recent years, phytotherapy have been studied with the concern for increasing quality of life, improving lower urinary tract symptoms (LUTS) as well as reducing prostate volume and the frequency of adverse events was similar to that of placebo. Linh Phu Khang Tue Tinh (LPKTT) capsules are formulated from 4 herbs widely used in traditional Vietnamese medicine - Panax notoginseng (Burkill) F.H.Chen - Tam thất (radix), Crinum asiaticum L. - Náng hoa trắng or giant crinum lily, Polygonum cuspidatum Willd. ex Spreng. (= Reynoutria japonica Houtt) - Cốt củ khí or Japanese knotweed (radix), Oldenlandia herbacea (L.) Roxb. (formerly known as Hedyotis diffusa Spreng.) - Bạch hoa xà thiẹ^t thảo or slender oldenlandia (herb). The preparation has been used in traditional Vietnamese medicine to treat nocturia, weak urine stream, urinary tract infection. According to modern studies,oided volume, total voided volume, the prostate and body weights, the ratio of prostate weight to body weight, prostate histology.

LPKTT reduced micturition frequency and increased the voided volume when compared to the control group (p<0.01). selleck chemical The results were equivalent to those of the alfuzosin ones (G4). LPKTT lowered prostate weight and the ratio of prostate weight to body weight when compared to the control group (p<0.01). These reductions were the same in the dutasteride ones. Histomorphology in G5 and G6 also showed that LPKTT inhibited TP induced prostatic hyperplasia. The results were similar to that in the dutasteride group. Microscopic images of prostate in G5 and G6 were almost similar to that of G1.

LPKTT capsules work to inhibit prostate proliferation in rats induced BPH by TP.

Raffia palm (Raphia hookeri G. Mann & H. Wendl) wine (RPW) is a natural beverage obtained from the R. hookeri consumed for refreshment and medicinal purposes. For medicinal purposes, it is used singly or as macerating agent for other medicinal plants for the treatment of several diseases.

This study investigates the effect of Raffia palm wine on dysregulated lipid metabolic pathways in testicular tissues of type 2 diabetic (T2D) rats.

Raffia palm wine (150 and 300mg/kg bodyweight) was administered to two T2D groups respectively, another T2D group was not administered treatment and served as negative control, while metformin served as the standard drug. After 6 weeks of treatment, the rats were sacrificed, and the testes collected. After weighing, the organs were homogenized in 20% methanol/ethanol and centrifuged at 20,000g to extract the lipid metabolites.

GC-MS analysis of the supernatants revealed an alteration of the metabolites on induction of T2D, with concomitant generation of 10 metabolitees as well as activation of pathways involved in energy generation, phospholipids, antioxidant activity, steroidogenesis and spermatogenesis suggest a therapeutic effect of Raffia palm wine against hyperglycemic-induced testicular dysfunction.
