... Selenium (Se) contamination due to industrial activities has received increasing concerns. Phytoremediation has been suggested to be an efficient and feasible way to remove Se from Se-contaminated environment. Recently, an arsenic (As) hyperaccumulator Pteris vittata L. (Chinese Brake fern) was found to be a Se accumulator. This study was carried out to investigate Se accumulation mechanisms conce ...

Abstract:
... Two osmoprotectants (proline – Pro; trehalose – Tre) were exogenously supplied to seedlings of rice cvs. Pokkali (PK – salt-tolerant) and Khao Dawk Mali 105 (KDML105 – salt-sensitive) to investigate their effects on plants exposed to 200 mmol/L NaCl for 6 days and 5 days after recovery from stress. The reduction of growth, increase in Na+ to K+ ratio, ...
... We aimed to determine the possible effects of the antioxidant agent (1 → 3)‐β‐D‐glucan on bortezomib‐induced rat testis damage. We used five groups of rats; control, (1 → 3)‐β‐D‐glucan (75 mg/kg), bortezomib group, bortezomib + (1 → 3)‐β‐D‐glucan groups (injection of (1 → 3)‐β‐D‐glucan after bortezomib and sacrificed at 48th or 72nd h). The effects of these substances were assessed by measuring th ...
... BACKGROUND: Organophosphorus pesticides (OP’s) are heavily constituted in agriculture, gardens, home and veterinary and although it is useful, there are concerns about the environment, safety and health of human and animals. In this study, we investigated the effects of a new oxime, (3Z)-5-Chloro-3-(Hydroxyimino)indolin-2-one (OXIME) against the alterations induced by malathion, an OP insecticide, ...

... Muscular dystrophies (MDs) are a group of heterogeneous genetic disorders characterized by progressive striated muscle wasting and degeneration. Although the genetic basis for many of these disorders has been identified, the exact mechanism of disease pathogenesis remains unclear. The presence of oxidative stress (OS) is known to contribute to the pathophysiology and severity of the MD. Mitochondr ...
... Cyclophosphamide (CTX) is an antitumor drug commonly used to treat various cancer types. Unfortunately, its toxic side effects, including gastrointestinal (GI) toxicity, affect treatment compliance and patients’ prognosis. Thus, there is a critical need of evaluating strategies that may improve the associated GI toxicity induced by CTX. In this work, we evaluated the capacity of epigallocatechin-3 ...

Abstract:
... (−)‐Epigallocatechin‐3‐gallate (EGCG), the most abundant polyphenolic constituent in green tea, is known as a powerful antioxidant but concomitantly possesses a prooxidant property. We investigated the effect of EGCG on phloxine B (PhB)‐induced photocytotoxicity in human T lymphocytic leukemia Jurkat cells. EGCG significantly potentiated PhB‐induced photocytotoxic effects, including the inhibition ...
... Most plants can now be cryopreserved using one of several protocols, providing a stable, long-term and low-cost backup for clonally propagated plants. However, some plants respond poorly to cryopreservation due to lack of tolerance to low temperatures or osmotic and chemical stress. Low temperatures cause chilling and freezing injury and these sub-lethal changes can lead to increased production of ...

... Because homocysteine (Hcy) is a risk factor for cardiovascular disease, and vitamin D deficiency can contribute to cardiovascular pathologies. In the present study, we tested the hypothesis that Hcy could impair energy metabolism, mitochondrial function, and redox status in heart slices of Wistar rats and that 1,25-dihydroxivitamin D3 (calcitriol) treatment could prevent such effects. Heart slices ...
... Antioxidant enzymes, such as catalase, superoxide dismutases (SOD), MnSOD and Cu/ZnSOD, protect cells by scavenging reactive oxygen species (ROS). Numerous studies have reported the anti‐cancer effects of 1,25‐dihydroxyvitamin D₃ (calcitriol) and its related analogues, seocalcitol and analogue V. In this study, canine bladder transitional cell carcinoma (cbTCC) cells were used to determine effects ...
... The putrescine analogue 1,4-diamino-2-butanone (DAB) is highly toxic to various microorganisms, including Trypanosoma cruzi. Similar to other α-aminocarbonyl metabolites, DAB exhibits pro-oxidant properties. DAB undergoes metal-catalyzed oxidation yielding H₂O₂, NH₄ ⁺ ion, and a highly toxic α-oxoaldehyde. In vitro, DAB decreases mammalian cell viability associated with changes in redox balance. H ...
... The contribution of 1,8-dihydroxy naphthalene (DHN) melanin to cadmium (Cd) tolerance in two dark septate endophytes (DSE) of the genus Cadophora with different melanin content was investigated in vitro. The DSE isolate Cad#148 with higher melanin content showed higher tolerance to Cd than the less melanised Cad#149. Melanin synthesis was significantly reduced by Cd in both isolates with uninhibit ...

Abstract:
... 1-Butanol, which is a specific inhibitor of phospholipase D, usually inhibits phosphatidic acid (PA) production and blocks the PA-dependent signaling pathway under stress conditions. However, the effects of 1-butanol on plant cells under non-stress condition are still unclear. In this study, we report that 1-butanol induced a dose dependent cell death in poplar (Populus euphratica) cell cultures. ...
... Juvenile Yoshitomi tilapia is often infected by pathogens and results in low-level survival rate. Bacillus subtilis, as a probiotic, may have beneficial effects on Y. tilapia with compound 1-deoxynojirimycin (DNJ), which has antibacterial activities. The effects of dietary probiotic supplementation on Y. tilapias were evaluated.Juvenile Y. tilapia was fed with B. subtilis for 56d. Y. tilapia was i ...
... Near eating-stage fruit of ‘Hayward’ and ‘Qihong’ kiwifruit (firmness 20 N) were treated with 0.5 µL L ⁻¹ 1-Methylcyclopropene (1-MCP) for 12 h at room temperature (23 ±1 °C), and then stored at 23 ± 1 °C for several days. Compared with control fruit, 1-MCP greatly delayed loss of firmness, and extended the room-temperature shelf life of ready-to-eat kiwifruit by an extra 8 d (‘Hayward’) or 10 d ( ...
... The storage life of optimum quality in postharvest hardy kiwifruit (Actinidia aruguta) is short. The effect of 0.8 μL L⁻¹ 1-Methylcyclopropene (1-MCP) on the storage quality of harvested hardy kiwifruit was investigated at temperature of 1 °C for 70 days. The results indicated that 1-MCP treatment maintained the firmness and total soluble solids content of hardy kiwifruit as well as inhibited the ...
... Kiwifruit, a cold-sensitive fruit, often suffers chilling injury (CI) during low-temperature storage. Ethylene plays an important role in regulating cold tolerance in many types of fruit postharvest. However, the effect of ethylene treatment alone or 1-methylcyclopropene (1-MCP) combined with ethylene treatment on CI in harvested kiwifruit under low temperatures remains unclear. In this study, fou ...
... Chronic alcoholism induces kidney injury (KI), leading to increased mortality in alcoholic hepatitis patients. Endoplasmic reticulum stress (ER) represents the main initiator of kidney diseases and alcoholic nephropathy.We used alcoholic nephropathy rat model followed by 10-dehydrogingerdione (10-DHGD) intake as potential modulator. This is to focus on ER/oxidative stress/inflammatory and apoptoti ...
... This study was performed to investigate the effects of dietary supplementation with garlic and turmeric powder as growth promoter agents on performance, carcass traits, serum biochemistry, and antioxidant enzyme activities of growing rabbits. A total of 112 New Zealand White rabbits (NZW) at 5 weeks of age were randomly assigned to seven treatments with four replicates. The dietary treatments cons ...
... The metabolic fate of ethion labeled with ¹⁴C-at the ethyl ester groups in soybean seeds following topical application to leaves was studied. Chromatographic analysis of soybean oil revealed the presence of the parent compound together with four metabolites which were identified as ethion monooxon, ethion dioxon, O-ethyl phosphorothioate and O,O-diethyl phosphorothioate. The effect of processing o ...
