conclusions the evidence that btx-a decreases ntg-induced cgrp-li and sp-li levels in trigeminovascular system suggests that btx-a attenuates migraine by suppression of neuropeptide release. btx-a injections for migraine at acupoint-sites and fixed-sites are effective. acupoint-sites btx-a administration shows more efficacy for migraine than fixed-sites application. results local btx-a injectio...

Use of the green solvent PolarClean demonstrates a potential route replacing toxic organic N -methylpyrrolidone in composite cathode slurry fabrication for Li ion batteries.

Problem from eating poisonous seafood can be seen in marine medicine[1-3]. Several marine animals can be toxic. The good examples are fishes[4], mussels[5] and shellfishes[6,7]. Horseshoe crab (Carcinoscorpius rotundicauda) can be poisonous and intoxication due to intake is possible[8]. Horseshoe crab poisoning can be seen in many countries with seacoasts including China and Thailand. In animal...

The present investigation assessed the effects of a metalloid (arsenic) and two heavy metals (cadmium and mercury), on the growth and metal accumulation in two medicinal plant species, artichoke (Cynara scolymus L.) and Savory (Satureja hortensis L.). The experiment was conducted hydroponically in spiked solution with different concentrations of arsenic (0, 20, 100, and 500 µM), cadmium (0, 10,...

The Isti Su hot spring is located in southeast of Salmas, in Western Azerbaijan, Iran. The area is a small part of Sanandaj-Sirjan geological zone which hosts many hot springs. The magma chamber of Salmas region is the main heat source of the hot springs in Isti Su area. Abundant rainfall and relatively long duration of snowfall as well as several deep faults in the area create the best conditi...

The nuclei of the lithium isotopes are fragile, easily destroyed, so that, at variance with most of the other elements, they cannot be formed in stars through steady hydrostatic nucleosynthesis. The Li isotope is synthesized during primordial nucleosynthesis in the first minutes after the Big Bang and later by cosmic rays, by novae and in pulsations of AGB stars (possibly also by the ν process)...

Local medicinal plants from Madina, Saudi Arabia, are used to cure various diseases. However, some can cause adverse health effects. Five different medicinal plants were collected in the city of Madina: mahareeb (Cymbopogon), sheeh (Artemisia), harjal (Cynanchum argel delile), nabipoot (Equisetum), and kafmariam (Vitex agnus-castus). In total, four toxic elements including Al, Pb, As, and Cd we...

BACKGROUND Tea is the most popular nonalcoholic beverage worldwide. In recent years, some Iranian studies have shown the occurrence of toxic elements in fresh or dried tea leaves as well as in brewed tea. The present study aimed to ascertain the health risks associated with exposure to toxic and essential element through black tea consumption in Iran by systematically reviewing the accredited a...

Abstract Stars with peculiar element abundances are important markers of chemical enrichment mechanisms. We present a simple method, tangent space projection (TSP), for the detection X -enriched stars, arbitrary elements , even from blended lines. Our method does not require stellar labels, but instead directly estimates counterfactual unenriched spectrum other unlabeled spectra. As case study,...
