Human leukocyte antigen (HLA) polymorphism and type 1 diabetes in the Moroccan population
Insulin-dependent diabetes mellitus or type 1 diabetes is an autoimmune multifactorial disease which has a great socio-economic impact. In Morocco, less is known about the contribution of Human leukocyte antigen (HLA) alleles to type 1 diabetes susceptibility. Our study focused on evaluating the distribution of class II HLA genes among Moroccan patients presenting type 1 diabetes coming from different regions...

Genetic parameters and path analysis of yield and its components in okra at different sowing dates in the Gangetic plains of eastern India
There is continuing need to identify traits that can facilitate selection of productive progenies. For this, 18 genotypes of okra [Abelmoschus esculentus (L.) Moench] were evaluated for the extent of genetic variability, heritability, correlation and path analysis among various morphological, reproductive and nutritional characters related to fruit yield over two growing seasons in the Gangetic plains of...

Process optimization and mechanistic studies of lead (II): Aspergillus caespitosus interaction for industrial effluent treatment
The lead (II) accumulation potential of various biosorbent had been widely studied in the last few years, but an outstanding Pb(II) accumulating biomass still seems crucial for bringing the process to a successful application stage. This investigation describes the use of non-living biomass of Aspergillus caespitosus for removal of Pb from Pb(NO3)2 solution in a batch system under different experimental...

Potential of Azolla filiculoides in the removal of Ni and Cu from wastewaters
Heavy metals constitute a serious health risk because they accumulate in soils, water and organisms. One of the methods of removing these pollutants from water and soil is the use of plants. There are many plants (hyperaccumulators) which have the ability to accumulate large amounts of heavy metals. One of them is the aquatic fern Azolla filiculoides, which can bind some substances. A dried A....

First report of grapevine dieback caused by Lasiodiplodia theobromae and Neoscytalidium dimidiatum in Basrah, Southern Iraq
In Basrah, grapevines suffer from dieback. Lasiodiplodia theobromae andNeoscytalidium dimidiatum were isolated from diseased grapevines, Vitis vinifera L. and identified based on morphological characteristics and DNA sequence data of the rDNA internal transcribed spacer (ITS) region. The results of the pathogenicity test conducted under greenhouse conditions for L....

Comparison of Luffa cylindrica L. sponge discs and Ca-alginate gel beads as immobilized matrices of Saccharomyces cerevisiae for bio-ethanol production from sugarcane molasses
The production of bio-ethanol from cane molasses (diluted to 15% sugar, w/v) was studied, using the yeast, Saccharomyces cerevisiae immobilized in luffa (Luffa cylindrica L.) sponge discs and in Ca-alginate gel beads. At the end of 96 h fermentation, the ethanol yields were 64.67 ± 0.016 and 65.21 ± 0.030 g/l molasses, with luffa and Ca-alginate entrapped S....

Biosorption of chromium by mangrove-derived Aplanochytrium sp.
The microbial dried biomass of Thraustochytrids is used as bioadsorbent for the removal of the chromium in aqueous solution. In this investigation, three species ofThraustochydrids namely Aplanochytrium sp., Thraustochytrium sp. andSchizochytrium sp. were tested for the efficiency of chromium accumulation by culturing in chromium-incorporated medium at 30°C for one...

Accelerated storage testing of freeze-dried Pseudomonas fluorescens BTP1, BB2 and PI9 strains
Freeze-dried cultures of Pseudomonas fluorescens are used in agriculture and microbiological industry. However, P. fluorescens is very susceptible to damage during freeze-drying and subsequent storage and it would be useful to increase culture viability during storage. The viability of freeze-dried P. fluorescens strains (BTP1, PI9 and BB2) was evaluated by using the Arrhenius model. This...

Effect of temperature on antibiotic properties of garlic (Allium sativum L.) and ginger (Zingiber officinale Rosc.)
Garlic and ginger are the two most common herbs used in traditional medicine practice for their antimicrobial activities. Moreover, in many countries, they are also used with boiled food preparations, which can destroy their important medicinal properties. We conducted an agar well diffusion assay with aqueous extracts of garlic and ginger to observe the effect of temperature on their antibiotic properties...

Modeling effluent heavy metal concentrations in a bioleaching process using an artificial neural network technique
Artifical neural networks practices were used to predict the recovery of heavy metals (Zn, Cu, Ni, Pb, Cd and Cr) from dewatered metal plating sludge (with no sulfide or sulfate compounds) using bioleaching process involving Acidithiobacillus ferrooxidans. The bioleaching process was operated as a completely mixed batch (CMB) reactor. The leaching performance data of the CMB reactor in terms of heavy metals was...

Effect of Hoodia gordonii leaf meal supplementation at finisher stage on productivity, carcass characteristics and meat sensory attributes of male Ross 308 broiler chickens
A nutritional experiment was conducted to determine the effect of Hoodia gordonii leaf meal supplementation at finisher stage (30 to 42 days old) on productivity, carcass characteristics and meat sensory attributes of Ross 308 broiler chickens. The chickens were fed a finisher diet supplemented with 0 (H0), 200 (H200), 300 (H300), 400 (H400), 500 (H500) or 600 (H600) mg of H. gordonii leaf...
