habitat recognition and knowledge of habitat requirements are extremely important to the wildlife conservation, particularly for endangered and vulnerable species. the purpose of the study was to determine which ecological and habitat factors contribute the distribution of black billed sandgrous (pterocles orientalis) in shirahmad wildlife refuge. sampling was performed in two season (spring an...

Objective: The methanol extracts obtained from the seeds of Hyoscyamus niger L. (Solanaceae) were investigated for their antimicrobial activities against the pathogens causing complicated urine tract infections. Methods: The seeds of plant were extracted with aqueous 60% methanol. The extract was screened against urinary tract pathogens (Enterococcus faecalis, Escherichia coli, Klebsiella pneum...

The aim of this work was to improve understanding of the regulation of alkaloid biosynthesis in two Solanaceae plants, Nicotiana tabacum (tobacco) and Hyoscyamus muticus (Egyptian henbane). In order to map the biosynthetic genes involved in the tobacco alkaloid pathway, a functional genomics-based technology was established by combining genome-based transcript profiling (cDNA-AFLP) with targete...

The systematic study of forensic toxicology dates from the end of the eighteenth century. It arose as a branch of forensic medicine concerned with the problem of proving deliberate poisoning in criminal cases. It was often very difficult to distinguish symptoms produced by many common poisonous plants like belladonna (deadly nightshade) and henbane from those of certain diseases. Medicines also...

The black walnut (Juglans nigra L.) is an underutilized fruit in the mid-hills of Nepal. However, the physico-chemical properties of Nepalese black walnut are almost unavailable in the literature. Four walnut growing districts namely Baitadi, Dadeldhura, Jumla and East Rukum selected and the black walnut collected at commercial maturity from the local markets. The physical properties w...

Introduction: Exposure to ionizing radiation can trigger adverse biological effects on healthy tissues, such as causing hematological toxicity and potential injury to different organs. Ionizing radiation has sufficient energy to liberate electrons from atoms leaving them with unpaired electrons; hence ionizing them and producing free radicals. In the current study, the...

 Nanofluids are colloidal suspension of nanoparticles in a base fluid and have superior thermal properties in comparison to their base fluids. Novel properties of nanofluids are yet to be explored to the highest potential. Currently extensive investigation has been done on thermal conductivity of metallic and oxide...
