OBJECTIVE Hypothyroidism is cited as an uncommon cause of ventilator-dependent respiratory failure. The objective of this study was to determine the incidence of hypothyroidism in patients with respiratory failure, receiving prolonged mechanical ventilation (PMV) with failure to wean, referred to a regional weaning center (RWC) for weaning. SETTING RWC. DESIGN Retrospective. METHODS Medic...

The broad-band ultrasonic spectroscopy technique allows the determination of changes in the relative water content (RWC) of leaves with contrasting structural features. Specifically, the standardized frequency associated with the maximum transmittance (f/f(o)) is strongly related to the RWC. This relationship is characterized by the existence of two phases separated by an inflexion point (assoc...

Hydrogen gas (H2) and carbon monoxide (CO) are involved in plant growth and developmental processes and may induce plant tolerance to several stresses. However, the independent roles and interaction effect of H2 and CO in adventitious root development under drought conditions have still not received the needed research attention. We hypothesize that there exists crosstalk between H2 and CO duri...

With increasing frequency and intensity of dry spells in the cocoa production zones West Africa, strategies for mitigating impact water stress on seedling survival are urgently required. We investigated effects applied potassium biomass accumulation, physiological processes varieties subjected to pot experiments a gauzehouse facility. Four levels (0, 1, 2, or 3 g/plant as muriate potash) were u...

A pot experiment was conducted to determine the response of two recent forage sorghum cultivars (JS-2002 and Chakwal Sorghum) and an old one (JS-263) to three levels of soil moisture (30%, 50% and 70% field capacity). Several traits were assessed addressing plant morphology, functional growth, leaf water status, biomass yield and water use efficiency (WUE). Soil moisture variation greatly affec...

Research Project of Optical Information Technology at ETL under RWC program is given in detail. In this program, firstly, so called CAD (computer-aided design) system for optical devices will be established for the purpose of acceleration on the development of semiconductor optical devices. Devices developed under the CAD system will be implemented into new types of optical information systems ...

BACKGROUND AND AIMS Since salinity and drought stress can occur together, an assessment was made of their interacting effects on leaf water relations, osmotic adjustment and net gas exchange in seedlings of the relatively chloride-sensitive Carrizo citrange, Citrus sinensis x Poncirus trifoliata. METHODS Plants were fertilized with nutrient solution with or without additional 100 mm NaCl (sal...

BACKGROUND In emergency research, obtaining informed consent can be problematic. Research to develop and improve treatments for patients admitted to hospital with life-threatening and debilitating conditions is much needed yet the issue of research without consent (RWC) raises concerns about unethical practices and the loss of individual autonomy. Consistent with the policy and practice turn to...

Drought is one of the major threats to cowpea productivity in tropical countries, and understanding its impacts germane ensuring food security a global context. The present study was established screen some accessions for drought tolerance at flowering stage pots under controlled conditions house. High significant differences were observed among wilting recovery traits, stomatal conductance, re...

Use of physiological parameters as fast tools to screen for drought tolerance in sugarcane: Drought is one of the major limitations to plant productivity worldwide. Identifying suitable screening tools and quantifiable traits would facilitate the crop improvement process for drought tolerance. In the present study, we evaluated the ability of four relatively physiological parameters (variable-t...
