The purpose of this study was to evaluate the physiological and biochemical changes that occur in mulberry (cv. local and Sujanpuri) plants under alkaline conditions in order to understand the response of these cultivars to alkalinity. Mulberry plants were subjected to different treatments using NaHCO3 and after 20, 40 and 60 days, different physiological and biochemical parameters were studied...

1. Studies of gastric function were made in preruminant calves fitted with a single abomasal cannula, re-entrant cannulas in the duodenum close to the pylorus and recording electrodes on the pyloric antrum and proximal duodenum. 2. Simultaneous measurements were made of gastric emptying of a saline (9 g sodium chloride/l) meal, myoelectric activity of antral muscle and plasma concentration of s...

This study examined whether expectancy of ergogenicity of a commonly used nutritional supplement (sodium bicarbonate; NaHCO3) influenced subsequent high-intensity cycling capacity. Eight recreationally active males (age, 21 ± 1 years; body mass, 75 ± 8 kg; height, 178 ± 4 cm; WPEAK = 205 ± 22 W) performed a graded incremental test to assess peak power output (WPEAK), one familiarisation trial a...

A cationic polymer containing tris(4,4′-dialkyl-2,2′-bipyridyl)ruthenium groups linked by aliphatic spacers was studied as a photosensitizer for the catalytic oxidation of water in the presence of colloidal IrO2. The polymer-colloidal IrO2 system photocatalytically reduced persulfate, a sacrificial electron acceptor, and oxidized water to O2 and H+ in solutions that were buffered at pH 6 by Na2...

Conduction slowing is the major in vivo effect of sodium channel blocking drugs. Although this action may promote arrhythmia suppression, apparently paradoxical arrhythmia aggravation does occur. The latter outcome is most frequently seen during treatment with the class IC agents such as encainide or flecainide, which are potent depressors of conduction even at usual plasma concentrations and h...

BACKGROUND Cisplatin, a platinum-derived chemotherapeutic agent, produces antineoplastic effects coupled with toxic neuropathic pain and impaired general health status. These side-effects complicate long term studies of neuropathy or analgesic interventions in animals. We recently demonstrated that pretreatment with sodium bicarbonate (4% NaHCO3) prior to cisplatin (3 mg/kg i.p. weekly up to 5 ...

The use of pesticides in agriculture has ensured the production different crops. However, have become an emerging public health problem for Latin American countries due to their excessive use, inadequate application, toxic characteristics, and minimal residue control. current project evaluates ability two strains algae (Chlorella Scenedesmus sp.) one cyanobacteria (Hapalosyphon remove excess ot...

In this research, several chemical extractants and modified Olsen methods were studied in 25 surface-calcareous soils (0-30 cm) for determining available phosphorus (P) for corn (Zea mays L.) plant. In this experiment, the highest correlation was obtained between extracted P by Olsen and Colwell methods (NaHCO3-extractable P) and dry weight of corn shoot (r =0.67 and 0.75, p
