A Method for Measuring RNA <em>N</em><sup>6</sup>-methyladenosine Modifications in Cells and Tissues

N6-Methyladenosine (m6A) modifications of RNA are diverse and ubiquitous amongst eukaryotes. They occur in mRNA, rRNA, tRNA, and microRNA. Recent studies ...

Acute administration of absolute ethanol (10 ml/kg) per os to fasted mice produced extensive renal failure as measured by a rise in blood urea nitrogen and creatinine. Pretreatment with oral administration of tetramethylpyrazine (TMP) prevented such failure. The maximal effect against absolute ethanol-induced renal failure could be observed 1 h after TMP administration. In order to further investigate the renal protective mechanism of TMP, experiments on lipid peroxidation and superoxide scavenging activity were conducted. Renal homogenates made from mice treated with ethanol showed that TMP pretreatment had an antioxidant effect. Mice in acute renal failure had higher malonic dialdehyde concentrations than those pretreated with TMP. The renal protective mechanism of TMP was attributed, in part, to its prominent superoxide scavenging effect, which protects the kidney from superoxide-induced renal damage.

Acute p.o. administration of absolute ethanol (1.0 ml/kg) to fasted rats produced extensive necrosis of gastric mucosa. Pretreatment with p.o. administration of propolis ethanol extract (PEE) could effectively and dose-dependently prevent such necrosis. This protective effect is called "cytoprotection. "The maximal cytoprotective effect against absolute ethanol (AE)-induced gastric mucosal lesion was observed 1 hour after PEE administration. A gross examination of the gastric mucosa showed a marked improvement in groups receiving PEE. In order to further investigate the gastric protective mechanism of PEE, lipid peroxidation (LPO) levels in vivo and in vitro were estimated. PEE exhibited dose-dependent superoxide scavenging activity and antioxidant effects on AE-induced LPO in rat gastric mucosal homogenates. It was concluded that the gastric protective mechanism of PEE was due, at least in part, to its ability to inhibit LPO, and hence indirectly protect the gastric mucosa from oxidative stress.

Androgen is the most important growth factor for the development and growth of prostatic adenocarcinomas. For patients with advanced prostate cancer, hormonal manipulation including castration and antiandrogen therapy is a well-established mode of treatment. The choice of hormonal therapy for prostate cancer depends not only on the desired progression-free and overall survival, but also on the patient's quality of life, treatment costs, and treatment toxicities.

Tolerability assessment of maximal androgen blockade with 50 mg daily of bicalutamide and castration in patients with advanced prostate cancer.

We propose the adjuvant effects of phospholipid liposome compositions using intranasal inoculation of a liposomal-Newcastle disease virus (NDV) vaccine in chickens. The immunogenicity of three liposome formulations was determined in chickens using the hemagglutination-inhibition (HI) test, nasal secretory immunoglobulin A and serum immunoglobulin A (IgG) antibody titers using the enzyme-linked immunosorbent assay. The immune response against NDV antigens was determined after immunization with neutral charged liposomes composed of egg phosphatidylcholine (EPC) (60 micromol), cholesterol (Chol) (15 micromol), and EPC-liposomes (EPC-Lip), which elicited strong systemic (serum) and local (nasal) humoral responses. However, the intranasal administration with cationic charged liposomes composed of EPC (30 micromol), stearylamine (SA) (15 micromol), Chol (15 micromol), and SA-liposomes (SA-Lip) induced poor humoral immune responses. Only the vaccine formulated with anionic charged liposomes composed of EPC (30 micromol), dipalmitoylphosphatidylserine (15 micromol), Chol (15 micromol), and phosphatidylserine-liposomes (PS-Lip) elicited the highest titers of HI antibodies. These are the first results to suggest that antigen delivery using EPC-Lip is very useful in enhancing antibody production at the mucosal site and in serum.

Evaluation of encapsulated Newcastle disease virus liposomes using various phospholipids administered to improve chicken humoral immunity.

Health related quality of life (HRQOL) is an important issue for long-term kidney transplantation (KT) patients. Nevertheless, few studies have focused on long-term HRQOL in KT recipients with a functional graft. Thus, the aim of this study is to describe the long-term (10-year) HRQOL of KT recipients.
