The aim of the present study is to evaluate the cytotoxic and genotoxic effects of silver nanoparticles (Ag-NPs) towards African catfish (Clarias gariepinus). Adult male catfish was exposed to 0, 25, 50, and 75 mgl–1 Ag-NPs for two weeks. Exposure to Ag-NPs exerted an increase in mortality rate and behavioural changes compared to control. A fluorescent microscopy examination was used to assess ...

An efficient in vitro protocol was standardized for Almond (Prunus dulcis) propagation using dormant axillary buds as explants. Explants were cultured on Murashige and Skoog (MS) and woody plant medium (WPM) supplemented with different concentration/combination(s) of phytohormones. MS basal medium showed lowest shoot induction and took longest duration for shoot initiation. Multiple shoots were...

A basic criterion in the selection of microalgae suitable as source of oil for biodiesel should be their actual capacity to produce lipids or, more properly, the fatty acid yield. Performance assessment of 10 preselected microalgae under both batch and continuous culture points to the latter approach as the most adequate for evaluating fatty acid productivity. Differences were patent in continu...

We have cloned a rat homologue of the Drosophila recessive oncogene lethal (2) giant larvae from rat brain by RT-PCR using primers prepared from sequences conserved amongst lgl family genes. Sequence analysis predicts that the rat rgl-1 gene encodes a 1,036 amino acid polypeptide with a molecular weight of approximately 112 kDa, which contains a domain characteristic of WD-40 proteins. Northern...

Abstract Salinity is one of the most important factors limiting plant growth and production around the world. Gibberellic acid is known as a strong growth stimulator, effective on seed germination and breaking of seed dormancy in various plant species. In order to study the response of Safflower,Sofeh cultivar, to salinity stress, a factorial experiment was conducted based on a randomized...

Eryngium foetidum L. is an important plant cultivated as leafy vegetable and for its essential oil, which is of high economical value in international market. Multiple shoots (17.8) were obtained through direct regeneration from leaf excised from field grown plants of E. foetidum and cultured on Linsmaier and Skoog’s Basal Medium (LSBM) fortified with BAP (1.5 mgl) and PVP (250 mgl). After subc...

Obesity is a chronic health condition characterized by the accumulation of excessive body fat which can lead to and exacerbate cardiovascular disease, type-II diabetes, high blood pressure, cancer through systemic inflammation. Unfortunately, visualizing key mediators inflammatory response, such as monoacylglycerol lipase (MGL) fatty acid amide hydrolase (FAAH), in selective manner profound cha...

background & aim: lemon verbena (lippia citriodora h.b.k.) is a richly scented herb and has a long history as a sacred and medicinal plant. select an appropriate medium in tissue culture is a necessity for success experimental: to evaluate the effect of 10 medium of previous researches for lippia micropropagation (1- ms medium supplemented with bap (3 mgl-1) + iba (0.1 mgl-1) + activated ch...

Cell-surface sialic acids are essential in mediating a variety of physiological and pathological processes. Sialic acid chemistry and biology remain challenging to investigate, demanding new tools for probing sialylation in living systems. The metabolic glycan labeling (MGL) strategy has emerged as an invaluable chemical biology tool that enables metabolic installation of useful functionalities...
