we investigated the effects of 25 mg-porphyrin-fullerene nanoparticles, ( 25 mgpmc16) smart ferroporphyrin nanoparticles, on pc12 cells exposed to oxygen-glucose deprivation/reperfusion. in order to explore its effect on cells under oxygen-glucose deprivation conditions, the cultures were pretreated with 25 mgpmc16 24 hours prior to oxygen-glucose deprivation/reperfusion. to initiate the oxygen...

The present work aimed to investigate the feasibility of using stable isotopes and inductively-coupled plasma mass spectrometry (ICP/MS) to study Mg absorption in rats. Male Wistar rats, aged 7 weeks and weighing 180 g, were used. They were fed on a semi-purified diet containing 1070 mg Mg/kg, and had free access to feed and distilled water. In the first experiment, after a 16 d adaptation peri...

The apoplastic permeability of the fungal sheath of two different ectomycorrhizal associations of Pinus sylvestris L. was analysed by laser microprobe mass analysis (LAMMA) and energy-dispersive X-ray spectroscopy (EDXS) after stable isotope labelling with 25Mg, 41K and 44Ca. Entry of 25Mg and 44Ca into the outer cortical apoplast of non-mycorrhizal roots was detected after 4 min of labelling. ...

24Na is a beta and gamma emitting radioisotope that widely used in medical engineering fields. It often radiotracing. This with half-life of 15 hours mostly produced cyclotrons. The cross-section to obtain various data about the production radioisotope. In cases where it not possible experimental data, missing can be completed calculations obtained compared experimental, saving time, cost effor...

We have theoretically analyzed the nuclear quantum effect on the nuclear magnetic shieldings for the intramolecular hydrogen-bonded systems of σ-hydroxy acyl aromatic species using the gauge-including atomic orbital technique combined with our multi-component density functional theory. The effect of H/D quantum nature for geometry and nuclear magnetic shielding changes are analyzed. Our study c...

cosmic rays in the upper troposphere (9000 meters to 15000 meters) initiate the followingnuclear chemical reaction: 1n + 14n => 14c + 1h. previous research has shown a strong effect of latitude onthe abundance of neutrons from cosmic rays. however, to date, there has been little exploration of therelationship between the latitude effect for cosmic-ray neutrons and latitudinal variations of stab...

INTRODUCTION To analyze the efficacy and safety of empagliflozin combined with other oral hypoglycemic agents in patients with type 2 diabetes mellitus. METHODS Pooled analysis of three phase III trials in patients with type 2 diabetes mellitus (n=1,801) who received placebo or empagliflozin 10 or 25mg once daily for 24 weeks, in combination with metformin, metformin+sulphonylurea or pioglita...
