Prevalence of urinary tract infection in both outpatient department and in patient department at a medical college setting of Bangladesh
Urinary tract infection remains one of the most common infections, both in the community and in the hospital. The causative pathogen profile varies from region to region, but Escherichia coli (E. coli) remain the most common causative pathogen. Organism responsible for the hospital acquired infection may have tendency to develop multiple drug resistance. This study […]
Cloning and sequence analysis of a flavanone 3-hydroxylase gene from Prunus persica (L.) Batsch
Anthocyanins as a type of plant flavonoids, is a kind of important plant secondary metabolites, which is catalyzed by a series of enzymes such as flavanone 3-hydroxylase (F3H). Here a F3H gene, designated as PpF3H, was cloned from Prunus persica (L.) Batsch. The full-length cDNA of PpF3H gene was 1453 bp in length, containing a […]
Cyanobacteria from a shallow Reservoir in Côte d’Ivoire
This paper is the result of the study of the Cyanobacteria flora from the raw potable water reservoir of Adzopé, located in South-Est of Côte d’Ivoire. The samples were collected monthly from January to December 2005. The species composition of the assemblage was compiled, accompanied by illustrations. Thirty three species of cyanobacteria were identified in […]
Bioactivity of medicinal plants Mentha arvensis and Peganum harmala extracts against Heterotermes indicola (Wasmann) (Isoptera)
As termites are hazardous causing damages to wooden structures leading to huge economic loss, efforts are directed towards the study of plant based products for effective and eco-friendly termite control. Present study was performed to determine the chemical constituents of the seed extracts from two medicinal plant species of Peganum harmala and Mentha arvensis against […]
Population analysis via fluctuating asymmetry in the wings of Culex quinquefasciatus say from selected breeding sites in Iligan City, Philippines
Fluctuating asymmetry (FA) refers to the unequal bilateral sides of an organism. It occurs when an individual is unable to undergo identical development on both sides of a bilaterally symmetrical trait. It measures the sensitivity of development to a broad array of environmental and genetic stresses. In this study, FA was used to measure developmental […]
The study of industrial town refinery sludge effects on Festuca arundinacea Schreb growth and phytoremediation capacity
This experiment designed to study the effects of Mashhad industrial town refinery sludge via its mixture with cultured medium in randomly 3 concentrations, 10%,15% , 20% weight on growth and physiological specifications and phytoremediation capacity of Nickle and Lead by lawn Festuca arundincea. The results showed that using sludge did not have significant effect on […]
Evaluation of antifungal activity of allyl isothiocyanate against Rhizopus stolonifer
Antimicrobial volatile substances from plants have become known as a suitable alternative to synthetic fungicides and food preservatives.Because of health risks for mankind and environment of chemical fungicides, nowadaysthe use of biological alternatives is growing fast.In this study, the antifungal activity of purified Allyl isothiocyanate from cruciferous plants was evaluated againstRhizopus stolonifer isolated from peach. […]
Genetic variation and differentiation of wild stocks of critically endangered Puntius sarana (Hamilton) and their F1 crossbreed through allozyme electrophoresis
The lower genetic variation and differentiation in wild parental stocks of critically endangered Puntius sarana and slight genetic improvement in their F1 crossbreed were inferred by horizontal starch gel electrophoresis with nine allozyme markers. Out of fifteen loci, four loci (EST-1*, GPI-2*, G3PDH-2*, PGM*) were polymorphic in F1 crossbreed progeny and in maternal parent, and […]
Biological evaluation and preliminary screening of endophytes of Taxus fauna for taxol production
Endophytic fungi of Taxus species, being considered as economically most promising source for taxol production, prompted the current study for screening of endophytic fungi associated with Taxus fuana of Pakistan. Two endophytic fungi Epicoccum sp.NFW1 and MucorhemalisNFW6 were explored for their biological activities and taxol production by utilizing bioassays, TLC, RP-HPLC and LC-ESI-MS analyses. Crude […]
Diversity and spatial distribution of stem borers and their natural enemies on off season sorghum, Sorghum bicolour (L.) Moench (Poaceae), in the Sudano-sahelian zone of Cameroon
Lepidopteran stem borers are among the most damaging insect pests of cultivated Poaceae in Africa. The objective of this study was to assess the diversity and the relative abundance of Lepidopteran stem borers and evaluate the larva-pupalparasitization in farmer’s fields. Surveys were conducted during two transplanted sorghum’ cropping seasons (2012/2013 and 2013/2014) in 3 agro-ecological […]
