Sporadic salinity caused by seawater intrusion is a serious concern for rice (Oryza sativa L.) production in the Red River Delta (RRD) of Vietnam, and guidance on-farm agronomic management needed. Three sets experiments – namely, trials (1) nitrogen (N) fertilizer use (replicated surveys farmer fields, including plots receiving zero N), (2) resistant varieties, (3) shallow irrigation were condu...

BACKGROUND The use of plants of the family Euphorbiaceae, particularly Euphorbia tirucalli (avelós) has been popularly widespread for treating a variety of diseases of infectious, tumoral, and inflammatory. AIM To demonstrated antimicrobial and immunomodulatory effects of these extracts, evaluating the effect of a topical treatment with an aqueous solution of avelós latex on the survival and ...

We assessed the clinical and pharmacological profile of the orally active V(1) vascular vasopressin (AVP) receptor nonpeptide antagonist SR49059 (SR) during the osmotic stimulation of AVP release in hypertensive patients. In a double-blind crossover-versus-placebo study, 24 untreated stage I or II essential hypertensive patients (12 whites and 12 blacks) received a single 300 mg oral dose of SR...

Abstract The insecticide resistance in Anopheles gambiae mosquitoes has remained the major threat for vector control programs but fitness effects conferred by these mechanisms are poorly understood. To fill this knowledge gap, present study aimed at testing hypothesis that antibiotic oxytetracycline could have an interaction with genotypes and consequently inhibit fecundity An. gambiae. Four st...

Following the diagnosis of Acanthamoeba keratitis in a contact lens wearer, the antimicrobial susceptibility of the clinical isolate and the environmental source of the infection were investigated. Contrary to previous reports, in vitro antimicrobial testing showed that the infecting strain was inherently resistant to propamidine isethionate. Restriction endonuclease digestion analysis of Acant...

UNLABELLED The antibacterial effects of tea-tree oil against the formation of methicillin-resistant Staphylococcus aureus (MRSA) biofilm on the surface of the tympanostomy tubes was evaluated. MATERIALS AND METHODS Silicone tympanostomy tubes were pretreated with normal saline for 12 hours, the control group (n=4), with 100% tea-tree oil, experimental group A (n=3), or with 50% tea-tree oil, ...

1. The pressor responses to hypertonic saline and angiotensin II introduced into the left lateral ventricle were both significantly greater in salt-sensitive (S) rats compared with salt-resistant (R) rats, with all rats on a low Na diet. 2. When S rats were given thiazide to nullify the pressor effect of dietary NaCl, their blood pressure averaged only 5 mmHg higher than that of the R rats; nev...

A mouse model of intestinal colonization with vancomycin-resistant enterococci (VRE) was used to study the effect of different beta-lactam antibiotics on establishment of VRE colonization. A clinical VanB VRE isolate, Enterococcus faecium C68 (102 or 104 cfu), was inoculated by gastric gavage in conjunction with subcutaneous administration of antibiotics. The MIC of ceftriaxone and ticarcillin ...
