Meteorologic factors and temporal variations of cardiac mortality in an urban setting in a desert climatic zone.

The aim of this investigation was to study, by use of the unbiased and rigorous techniques of lagged cross-covariance and spectral analyses, the associations between daily cardiac mortality and weather conditions in Beersheba, an urban center situated in a hot and dry climatic zone. The results of the analyses point to the existence of seasonal differences in mortality, with a peak in winter. Of greater interest is the statistical documentation of temporal associations between short-term increases in daily mortality and certain weather situations corresponding to the transitional periods of turbulent atmosphere with below normal air temperatures, strong gusty winds and a drop in relative humidity, i.e., conditions accompanying the intrusion of a winter cold wave. The crests in short-term mortality occurred most often within a week of the intrusion of the cold air masses. No consistent cross association was found between high summer temperatures and mortality. The results of this investigation are discussed in the light of those previously reported for Tel Aviv (a coastal city) and Jerusalem (a city situated at a high altitude).

Genomic exploration of Bacillus paralicheniformis TB197: an agrobiotechnological tool from the Sonoran Desert.

Climate change and the harmful effects of extensive agrochemical use for plant nutrition and pest control on soils, the environment, and human health are driving the search for sustainable alternatives that reduce their use while increasing plant resilience. In regenerative agriculture, microorganisms have become valuable tools, acting as biological control agents or biostimulants, such as plant growth-promoting rhizobacteria, and/or to enhance plant performance under abiotic stress. The genus Bacillus is well known for its versatile interactions with plants. Specifically, Bacillus paralicheniformis TB197 has demonstrated high efficacy in controlling phytopathogenic nematodes and adapting to diverse soil and crop conditions. Based on these traits, we explored the agricultural potential of this strain through genomic analysis and in vitro and in vivo assays. Gene analysis identified functions related to three main areas: (i) stress resistance and plant colonization, (ii) plant growth promotion, and (iii) phytopathogen control. The strain showed high tolerance to salinity and temperature, promoted plant growth, and exhibited strong antifungal activity. These findings highlight the potential of the TB197 strain as a promising candidate for developing next-generation bioinoculants.IMPORTANCEThe use of beneficial microorganisms is a pivotal strategy for mitigating the environmental impacts of intensive agriculture while preserving crop productivity. Bacillus paralicheniformis TB197 is a native desert soil bacterium with genetic traits associated with stress tolerance, plant growth promotion, and suppression of plant pathogens. In this study, we employed a multifaceted approach integrating genomic analysis and functional assays to demonstrate the strain's multifunctional potential as an agricultural bioinoculant. The results of the study demonstrate that a singular bacterial strain can integrate multiple beneficial functions relevant to sustainable agriculture. This work contributes to the field of applied microbiology by expanding the understanding of how environmentally adapted bacteria can serve as biological alternatives to chemical inputs in agroecosystems.

Effect of environments on human functions: studies on water metabolism.

The purpose of this review is to study general behaviour of human systems with respect to the environmental conditions. This type of work will be of profound significance to record the effect of medical treatment in various climatic zones of the world (Arayne and Saify, 1975). We attempted to discuss various facts which would be helpful for tackling the health problems of the people residing in these areas. The statistical data is avoided at the moment and a descriptive pattern is adapted in order to express views, about one of the important aspects of medical science.

[Problems arising from the health status evaluation and certification of diseases developed in countries with different climatic conditions].

Based on the Polish regulations, the authors present problems and difficulties in qualification for business departures into the tropics, as well as diagnostic and certification procedures related to those whose health has been injured during their business trip to the tropics. The authors postulate a greater attention to be paid to this problem and explanation of some doubts resulting from interpretation of operative regulations.

[Physical work capacity as a criterion of human resistance under the hot climatic conditions of an arid zone].

In heat discomfort, physically trained subjects had a high and stable physical working ability (PWA) whereas untrained subjects revealed a considerable decline of the parameter. A lesser work was performed with a greater tension of the cardiorespiratory system. The data obtained suggest a high and stable PWA is one of the main criteria of the organism's adaptation to hot climate conditions of the arid zone.

Statistics of 204 cases of cancer observed in Saharian populations from 1969 to 1976 and a comparison with studies previously made in this area and statistics from other countries. Skin cancer have a special frequence which may be related to climatic and atmospheric environment.

Physiological responses of dogs on exposure to hot, arid conditions. Acid-base status.

Acid-base parameters were determined in chronically cannulated dogs exposed to ambient temperatures increasing from 25-47 degrees C (with relative humidity below 30%). pH increased from 7.409 +/- 0.004 (S.E.M.) to 7.538 +/- 0.017, PaCO2 decreased from 33.0 +/- 0.5 to 20.9 +/- 1.2 torr, and [HCO3-] decreased from 20.9 +/- 0.3 to 17.2 +/- 0.4 mEq/l. Minimal base excess change, together with a rapid return to normal parameters upon recooling to 25 degrees C, suggests that the stress is almost exclusively respiratory, with little metabolic involvement. Analysis of serial exposures shows no acclimatization effect in acid-base status. This suggests the possible existence of natural acclimation to heat in dogs maintained in a warm climate, permitting excellent tolerance of hot, arid conditions with limited acid-base disturbance.
