Weight loss is an effective intervention for diminishing disease burden in obese older adults. Pharmacological interventions that reduce food intake and thereby promote weight loss may offer effective strategies to reduce age-related disease. We previously reported that 17α-estradiol (17α-E2) administration elicits beneficial effects on metabolism and inflammation in old male mice. These observ...
Establishment and biological characteristics of oxaliplatin-resistant human colon cancer cell lines.
BACKGROUND AND OBJECTIVE Chemotherapy is the main treatment for colon cancer, while multidrug-resistance is the main reason for chemotherapy failure and tumor relapse. This study was to establish two oxaliplatin-resistant colon cancer cell lines and evaluate their biological characteristics. METHODS Oxaliplatin-resistant colon cancer cell lines SW620/L-OHP and lovo/L-OHP were established in v...
Colorectal cancer (CRC) is one of the most common reasons for cancer-associated mortality worldwide. The present study aimed to investigate the drug resistance mechanism of the oxaliplatin (OXA)-resistant HT-29 cell line (HT-29/L-OHP) and examine the expression of lysosome-associated protein transmembrane 4β (LAPTM4β), a drug resistance-associated gene. In the present study, a drug concentratio...
Urinary 1-hydroxypyrene (1-OHP) is a biomarker of polycyclic aromatic hydrocarbon (PAH) exposure. We measured urinary 1-OHP in 48 children 3 years of age in Mariupol, Ukraine, who lived near a steel mill and coking facility and compared these with 1-OHP concentrations measured in 42 children of the same age living in the capital city of Kiev, Ukraine. Children living in Mariupol had significant...
When propafenone is given with digoxin, digoxin serum concentrations increase. Although the digoxin-propafenone interaction is well known clinically, the mechanism by which propafenone interferes with digoxin elimination is unclear. To test the hypothesis that propafenone or one or both of its two major metabolites, 5-hydroxypropafenone (5-OHP) and N-depropylpropafenone (NDPP), inhibit the P-gl...
To achieve sufficient antitumor activity for colorectal carcinoma, optimization of the therapeutic regimen is of great importance. The aim of the present study was to investigate the effects of polyethylene glycol (PEG)-liposomal oxaliplatin (L-OHP) on the induction of apoptosis in human colorectal cancer SW480 cells and how the nuclear factor-κB (NF-κB) pathway may contribute to mediating PEG-...
Thermal performance of a 6m-long Oscillating Heat pipe (OHP) for balloon-borne General Anti-Particle Spectrometer (GAPS) experiment has been investigated. The developed OHP is a closed loop type and U-shaped due to the mission detector requirements. R410A is selected as the working fluid for the use at low temperature. We achieved a thermal conductance of 18.7 W/K for 150 W heat input with 16 t...
OBJECTIVE To estimate whether administration of 17α-hydroxyprogesterone caproate can prevent neonatal morbidity in multiple pregnancies by reducing the preterm birth rate. METHODS We conducted a multicenter, double-blind, placebo-controlled randomized trial in 55 obstetric clinics in the Netherlands. Women with a multiple pregnancy were randomized to weekly injections of either 250 mg 17α-hyd...
We investigated the androgenic effects of 17α- methyltestosterone (MT) on gonadal sex reversal in juvenile red spotted grouper Epinephelus akaara. The fish were immersed in 17α-MT at 1 and 5 mg/L. Treatment method of 17α-MT was once weekly for 4 and 8 weeks. Fish were sampled at 12 months after end of the treatment period in order to histological analysis. At the initiation of an experiment (70...
Polycyclic aromatic hydrocarbons (PAH) are common air pollutants generated from incomplete combustion. The inhalation of exhaust fumes in urban areas has been suggested to be an additional contributing factor. This study investigated the influence of urban traffic exposure, personal lifestyle factors and metabolic enzyme polymorphisms on the urinary 1-hydroxypyrene (1-OHP) level, approximating ...
