In gammarids, behavioural and biochemical biomarkers are commonly used in ecotoxicological studies. In our study, we have investigated seasonal variations of several biochemical biomarkers in Gammarus roeseli, a freshwater species. Organisms were sampled monthly over a 1-year period. Gender was distinguished to measure antioxidant enzyme activities like total glutathione peroxidase (GPxtot), se...

Citation of the various papers published in one and the (the calendar year following the year of publication), we also same journal is highly skewed. Journals with a high impact factor obtain this high value by frequent citation of only a limited number of their papers and, on the other hand, journals with low impact factors publish many papers that remain uncited [1]. Thus, mere publication of...

Abiotic stress exerts significant impact on plant's growth, development, and productivity. Productivity of crop plants under salt stress is lagging behind because of our limited knowledge about physiological, biochemical, epigenetic, and molecular mechanisms of salt tolerance in plants. This study aimed to investigate physio-biochemical, molecular indices and defense responses of selected wheat...

Toxicity of cypermethrin insecticide was evaluated in the liver of 16-day old chick embryo following administration of a single sub-lethal dose of cypermethrin into the eggs on day ‘0’ of incubation. The biochemical analysis of the liver revealed that the activities of aspartate aminotransferase, alanine aminotransferase and lactate dehydrogenase were significantly increased. The activities of ...

When studying the role of the locus coeruleus (LC) in the regulation of seizure susceptibility in rats, we found that bilateral LC lesion significantly lowered the electroshock seizure threshold for the tonic extension of forelegs. The pattern of maximal electroshock seizure was not affected by LC lesion, although the recovery time was slightly prolonged. In the pentylenetetrazol (PTZ) seizure ...

A study was conducted to investigate the impact of NaCl on the physiological and biochemical traits of Chlorella vulgaris Beijerinck. In order to determine the impact of NaCl, Chlorella was exposed to different concentrations of NaCl ranging from 0.1-0.4M besides control over a period of 30 days. It was found that total chlorophyll contents stimulated at lower concentrations of NaCl (0.1 and 0....

abstract background and objectives: soil salinity is one of the most important limited factors of plant productions. physiological drought resulting from salinity stress is one of the main reasons of limiting water absorption from soil. moreover, increasing the salt absorption by plants cause to disorder in physiological and cellular processes. spearmint (mentha spicata l.) is from lamiaceae fa...

Research Problem: Cassava leaves play an important role in the diet of Central African population. Several studies have investigate composition nutrients cassava but only few study focused on impact mosaic virus disease, main threat production sub-Saharan Africa, nutritional value infected leaves. The objective this work is to determine content and anti-nutritional compounds by healthy leaves.&...

background and objectives:hormozgan province is located in the south of iran, bordering waters of the persian gulf and oman sea. due to the antioxidant potential of plants which might be responsible for their medicinal properties, the antioxidant properties of four medicinal plants of the region were evaluated. methods: the antioxidant properties of chrozophora obliqua, daphne mucronata, salvia...
