Role of medicinal plants in free radical induced sickle cell anemia

Sickle cell disease (SCD) is a common recessively inherited disorder of hemoglobin affecting peoples everywhere in the world. The homozygous state (SS) is associated with complications and reduced life anticipation. The symptoms including, shortness of breath, heart palpitations, abdominal pains, aches and pains in the muscle. One cause of this disease is oxidative stress which […]

An efficient DNA extraction protocol for medicinal plants

This paper communicates a simple and cost effective protocol for isolation of genomic DNA from dry parts of Berberis and Mentha. This protocol was applied to 5 species of Berberis and 4 species of Mentha collected from different locality of Kunhar Valley. In this protocol 5 M NaCl, 2% CTAB, 1% PVP and 0.1 % […]

The use of geographical information system (GIS) for the assessment of ecological capability on forest land, in the Northern part of Iran

No doubt, the protection of soil and water resources requires a systematic approach and appropriate with ecological conditions of basins. In this context and in order to achieve sustainable management and development of a model to assess the suitable ecological capability, this study was carried out in the basin Masal, Gilan province and northern Iran. […]

Study relationship of drought tolerance indices in wheat (Triticum aestivum) genotypes

Drought is a wide-spread problem seriously influencing wheat (Triticum aestivum) production and quality, but development of resistant cultivars is hampered by the lack of effective selection criteria. The objective of this study was to evaluate the ability of several selection indices to identify drought resistance cultivars under drought stress conditions. Eight wheat cultivars (Triticum aestivum) […]

Status survey on carnivores and prey in Kalesar National Park and Wildlife Sanctuary in Haryana, India

Abundance of carnivore and their prey reflects the habitat richness of an area. This is because carnivores occupy the top position in the food pyramid. However the survivability of carnivore depends upon the abundance of prey population in an area. Conservation of carnivore may not be practical until there is viable population of prey species. […]

Effects of hydraulic installations on the prevalence of Plasmodium falciparum in the Logone plain in Far North region of Cameroun

The prevalence of Plasmodium falciparum was determined out on 420 persons in two villages of a hydro-arranged perimeter and two others out of the water intake perimeter in the Far North region in Cameroon. Thick and thin blood smears were stained with Giemsa. Species-specific densities of plasmodia were estimated under a light microscope at high […]

Study on measurement and statistical analysis of adherent soil chemical compositions of leguminous plants and their impact on nitrogen fixation

The most important step of this study is to conduct the careful assessment of the interaction of leguminous plants with soil chemical compositions. The amount of chemical components as well as total nitrogen in adhered soil of ten species of leguminous plants and two species of non-leguminous plants with normal soil (controls) were measured at […]
