RESUMO
Climate changes and the related rise in the frequency of excessive weather proceedings have a strong influence on the physical, chemical, and hydrological processes in soils. Recently the investigators confirmed that the use of biological treatments and resources to overcome abiotic stress is fruitful. Thus, pomegranate peel extract (PPE) because of its high efficacy and/or compost application could improve soil characteristics, soil organic matter and nutrient status. This effect may be referred back to the enhancement in the plant antioxidative defense system against stress conditions. This experiment was done to study the influence of spraying wheat plants with pomegranate peel extract (PPE) with and/or without soil compost added under salt stress on some growth parameters and physiological aspects. Wheat plants were grown in the presence or absence of compost in the soil and foliar sprayed with PPE (600 and 1200 mg L-1) under salt irrigation (3000 and 6000 mg L-1). Growth and yield traits were decreased with salinity stress. High levels of PPE (1200 mg L-1) induced the highest values of osmoprotectants (Total soluble sugars, total soluble protein, proline and free amino acids) in both unstressed or salinity-stressed plants presence or absence compost. Using compost in soil for cultivating wheat plants and PPE spraying treatments increased growth traits photosynthetic pigments and yield components. Moreover, these treatments increased the accumulation of minerals content (N, P, K and Ca) in plants. In general, the results of correlation coefficients showed a significant strong positive relationship among measured yield traits and other tested parameters. The correlation between 1000-grain Wt. and grain Wt./spike (r = 0.94**) was the highest. Meanwhile, a strong negative correlation coefficient between Na% and all yield parameters was recorded. Compost adding to soil and spraying pomegranate peel extract is a successful method for increasing wheat growth, yield and improving the nutritional value of the produced grains under salt stress.

A combination of abiotic stresses in sandy soils, such as saline water, saline soil, and lack of nutrients, affects productivity of faba bean. In this study, organic amendments and biostimulants (VIUSID® agro) were used in combination to increase yield of faba bean seed as well as the protein content under a sandy soil and irrigation affected by salt water. Two field experiments were carried out during two successive winter seasons of 2016/2017 and 2017/2018. A split-split-plot design in a randomized complete block was used. The main plots were allotted to the organic amendments, rates of biostimulants (VIUSID® agro) were assigned to sub-plot, and the cultivars were applied to sub-sub-plot. The results showed that the treatment of plant compost applied as an organic amendment and 1.5 L ha-1 of biostimulants (VIUSID® agro) with foliar application significantly increased seed yield of cultivars, Sakha-4, Sakha-1, and Giza-843 by 17.2, 33.0, and 19.8 % respectively, compared to control under a sandy soil and irrigation water affected by salts. The interaction between Sakha-1 cultivar, plant compost, and 1.5 L ha-1 of biostimulants (VIUSID® agro) achieved the optimal combination, providing the highest grain yield, as compared to all other treatments. The combination of these treatments is recommended in order to improve faba bean productivity under similar conditions.(AU)

A total of 187 isolates from 470 clinical specimens were collected from three hospitals in El-Minia governorate and identified as 132 Staphylococcus aureus strains and 55 coagulase-negative staphylococci (CoNS) strains. Susceptibility of isolates to antimicrobial agents was tested by the agar dilution method. The isolated S. aureus strains showed low resistance to vancomycin (1.5 percent), amikacin (2.3 percent) and gatifloxacin (3.8 percent). Vancomycin was the most effective antibiotic against CoNS. The ampicillin-resistant isolates were tested for â-lactamase production where, 61.7 percent of S. aureus and 42.9 percent of CoNS were positive for â-lactamase enzyme. Beta-lactamase producing strains were screened for their plasmid profile using alkaline lysis method. Some of these strains carried at least one plasmid suggesting plasmid-mediated antibiotic resistance. When cells of these strains were exposed to curing agent ethidium bromide, the production of the â-lactamase was lost. Resistance by efflux was studied by a modified fluorometric assay. Addition of uncoupler carbonyl cyanide m-chlorophenylhydrazone (CCCP) increased norfloxacin accumulation in quinolone resistant S. aureus strains, suggesting endogenous energy-dependent efflux. Combinations of ciprofloxacin with four antimicrobial agents against methicillin resistant S.aureus (MRSA) strains were investigated using decimal assay for additivity (DAA) technique. Synergistic interaction was observed between ciprofloxacin and oxacillin. ciprofloxacin plus cefepime and gentamicin appeared to be additive, while ciprofloxacin plus erythromycin was antagonistic.

RESUMO
Ambient air VOC samples were collected at surface air quality monitoring sites, near sources of interest, and aloft on the US (El Paso) and Mexican (Ciudad Juárez) side of the border during a six-week period of the 1996 Paso del Norte Ozone Study. Samples were collected at five sites, three on the US side and two on the Mexican side, during nine intensive operation days when high ozone levels were forecast for the area. Six other sites were sampled to characterize up-wind, down-wind and other emission sources. Samples for determining source profiles were collected for rush hour traffic, propane-powered bus exhaust, automobile paint shop emissions, propane fuels, and industrial manufacturing in Cd. Juárez and a refinery in El Paso. Most samples were collected in electro-polished stainless steel canisters for determination of C2 to C(10+) hydrocarbons by GC-FID. Carbonyl samples were collected on DNPH impregnated cartridges at three surface sites during aircraft flights and analyzed by HPLC. This paper presents the spatial and temporal characteristics of VOC species concentrations and compositions to examine the differences and similarities of the various locations and time periods. Overall surface, total non-methane hydrocarbon values ranged from 0.1 to 3.4 ppmC with the highest concentrations being recorded in the morning and evening at five vehicle-dominated sites, three in Cd. Juárez and two in El Paso. Toluene in El Paso samples and propane, which is used as a cooking and transportation fuel in Cd. Juárez, were the most abundant hydrocarbons. The most abundant carbonyls were acetaldehyde, acetone and formaldehyde.

El cáncer colo-rectal es muy frecuente en Argentina. Es el tercer cáncer más frecuente luego del de piel y mama en la ciudad de Rosario. Nuestra población usualmente ignora los síntomas del cáncer colónico y el diagnóstico precoz es infrecuente. Las Sociedades de Gastroenterología, Cancerología y Colonoproctología de Rosario organizaron una camapña de disfusión durante julio, agosto y setiembre de 1985 en Rosario en Rosario y sus alrededores (población: 1.300.000) por medio de afiches, mensajes en los diarios, radios y especialmente por televisión, describiendo en la posibilidad de prevención por diagnóstico y extirpación de pólipos. Afiches y panfletos fueron distribuidos en lugares públicos y cartas información fueron enviadas a todos los médicos de Rosario. Se realizó un Curso Internacional de Actualización sobre cáncer de colon y recto. Los resultados de la campaña fueron evaluados a través del Registro de Tumores de Rosario e instituciones privadas. Desde setiembre de 1984 hasta febrero de 1985 la incidencia mensual de pólipos y cáncer fue revisada. El promedio mensual de cáncer de colon y recto fue de 39; antes de la campaña 41, durante la misma 49 y después de ella 26. El promedio de incidencia mensual de pólipos fue de 18,9. Antes de la campaña 17,5, durante la misma 27,5 y después de ella 13,8. Estos resultados fueron estudiados estadísticamente por el test paramétrico de Mann y Whitney. Durante la campaña se observó un incremento levemente significativo (p=0,05) de cáncer y pólipos diagnosticados. Se concluye que la campaña logró sus objetivos de difusión pública pero se considera que es necesario insistir con campañas más extensas y periódicas

Colorectal cancer is very frequent in Argentina. It is the third most frequent cancer, after skin and breast tumor in the city of Rosario. Our population usually ignores the symptoms of colonic cancer and early diagnosis are infrequent. The Societies of Gastroenterology, Oncology and Colonoproctology organizes a public awareness campaign during july, august and september 1985 in Rosario and its surrounding (population 1,300,000) by means of newspaper, radio and specially by television, describing the symptoms were present, as well as insisting of the possibility of prevention by endoscopy diagnosis and removal of polyps. Literature and pamphlets were distributed, and information letters were send to all the physicians in Rosario. An International update meeting on colon and rectal took place. The results of this campaign were evaluated through the Tumor Registry of Rosario. Since september 1984 still february 1986, the monthly incidence of polyps and cancer of the colon and rectum was recorded. The monthly average incidence of polyps was 18.9. Previous to the campaign, the monthly average of diagnosed polyps was 17.5; during the campaign, 27.5; and after it, 13.8. The monthly average of colorectal cancer was 39, before the campaign, 41; during the campaign, 49, and 26 afterwards. These results were statistically studies by the parametric test of Mann and Whitney. During the campaign a significant (p = 0.05) increase of diagnosed polyps and cancers, was found. Our conclusion is that the awareness was successful, but we think that it is necessary to insist with periodic and longer campaigns.
