Abstract The purpose of this study is to explore the physiological mechanisms underlying attenuation Cd toxicity using Se in two cherry tomato cultivars ‘Hanluzhe’ (HLZ) and ‘Lvfeicui’ (LFC), with low high accumulation rates, respectively. Hydroponic experiments were conducted 2.5 μmol L −1 was applied hydroponic solution 50 Cd. photosynthetic parameter, antioxidant enzyme activities, non-enzym...

OBJECTIVES The beneficial effects of macrophage-targeted glucocerebrosidase (Ceredase) in patients with Gaucher disease are well established. A minority of recipients develop transient nonneutralizing antibodies to the exogenous enzyme. A 7-year-old patient with type 3 Gaucher disease whose clinical course began to deteriorate while receiving Ceredase developed a progressively increasing titer ...

Washed vegetative cells of various species of aerobic spore-forming bacteria sporulate abundantly when shaken in distilled water in air. The spores thus formed possess the same heat resistance as spores formed in a complete growth medium. Various factors influencing sporogenesis in water are described. Glucose in low concentration completely suppresses sporogenesis under these conditions and th...

The ADH2 gene codes for the Arabidopsis glutathione-dependent formaldehyde dehydrogenase (FALDH), an enzyme involved in formaldehyde metabolism in eukaryotes. In the present work, we have investigated the potential role of FALDH in detoxification of exogenous formaldehyde. We have generated a yeast (Saccharomyces cerevisiae) mutant strain (sfa1Delta) by in vivo deletion of the SFA1 gene that co...

to find the protective role of exogenous nitric oxide (no) on salinity-stressed rice seedlings, a crd-based factorial experiment with three replications was conducted in agronomy laboratory of the faculty of agricultural sciences, university of guilan, in 2012. the experimental design consisted of healthy and vigorous seedlings of two rice cultivars, khazar and goohar, the last already known as...

Ribonucleotide reductase activity in cell-free tissue extracts from Yaba monkey tumors, spleen, kidney, liver, and muscle has been measured in vitro. The specific activity of the enzyme in the Yaba tumor extracts was approximately two times that observed in normal muscle tissue extracts and ten times that in normal liver, spleen and kidney extracts. The specific activity in Yaba tumor extracts ...

Given the increasing importance of boron (B) toxicity, present study investigates roles glutathione (20 mM, GSH) and proline mM) in improvement wheat (Triticum aestivum cv. Altındane) resistance to B toxicity (10 mM B). The plants were raised hydroponic culture with control, B+glutathione, B+proline, proline. B+glutathione B+proline resisted detrimental influences on root shoot lengths, total c...

Sepiapterin reductase (SPR) is known as an essential enzyme for the biosynthesis of tetrahydrobiopterin. SPR belongs to the short-chain dehydrogenase/reductase (SDR) family and also reduces various exogenous carbonyl compounds including phenylpropanedione. We found in the present study that phenylpropanedione decreased the rate of proliferation of PC12 cells and that this rate was further dimin...

An experiment was conducted to evaluate the efficacy of exogenous enzymes supplementation (ES) on performance, carcass traits and some blood parameters of broilers chickens. One hundred and eighty day old chicks with 40 ± 2 g initial body weight in a completely randomized design with 3 treatments and 4 replications were fed experimental diets included, 1) basal diet no enzymes (control), 2) bas...

Biochar (BC) is a material that finds many applications in agriculture and environmental activities. The aim of the study was to define influence biochar produced from various organic materials: mellow compost (MC), stabilized municipal sewage sludge (MSS), pine sawdust (PS), sycamore (SS) oak leaves (OL) on soil enzyme activity, as well its relations with carbon nitrogen content. After 60-day ...
