Lipopolysaccharide enhances the cytotoxicity of 2-chloroethyl ethyl sulfide.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND The bacterial endotoxin, lipopolysaccharide (LPS), is a well-characterized inflammatory factor found in the cell wall of Gram-negative bacteria. In this investigation, we studied the cytotoxic interaction between 2-chloroethyl ethyl sulfide (CEES or ClCH2CH2SCH2CH3) and LPS using murine

Glutamine and glutaminolysis are required for efficient replication of infectious spleen and kidney necrosis virus in Chinese perch brain cells.

Viruses rely on host cellular metabolism for energy and macromolecule synthesis during their replication. Infectious spleen and kidney necrosis virus (ISKNV) causes significant economic losses in the Chinese perch (Siniperca chuatsi) industry worldwide. However, little is known about the

A dorsal model for cutaneous vesicant injury by 2-chloroethyl ethyl sulfide using C57BL/6 mice.

Numai utilizatorii înregistrați pot traduce articole

To evaluate stem cell-derived therapeutics for cutaneous vesicant injuries, we developed a dorsal exposure model using C57BL/6 black mice and half-mustard, 2-chloroethyl ethyl sulfide (CEES). The dorsal side of a mouse was exposed to 1-5 microl of CEES for 10 minutes and then decontaminated. The

Activation of MAPK/AP-1 signaling pathway in lung injury induced by 2-chloroethyl ethyl sulfide, a mustard gas analog.

We reported earlier that the activation of free-radical-mediated tumor necrosis factor-alpha (TNF-alpha) cascade is the major pathway in the inflammatory lung disease induced by 2-chloroethyl ethyl sulfide (CEES), a mustard gas analog. TNF-alpha induces activating protein 1 (AP-1) activation via

Prophylactic protection by N-acetylcysteine against the pulmonary injury induced by 2-chloroethyl ethyl sulfide, a mustard analogue.

Numai utilizatorii înregistrați pot traduce articole

Mustard gas exposure causes adult respiratory distress syndrome associated with lung injury. The purpose of this study was to investigate whether an antioxidant, such as N-acetylcysteine (NAC), has any protective effect. Guinea pigs were given single exposure (0.5-6 mg/kg body weight) of

Glutamine is required for red-spotted grouper nervous necrosis virus replication via replenishing the tricarboxylic acid cycle.

Numai utilizatorii înregistrați pot traduce articole

Glutamine, one of the most important nutrients, plays a vital role in carbon metabolic pathway and has been reported to be required for the replication of several human DNA viruses. However, whether glutamine is required for RNA virus replication and the related mechanism remains elusive. Nervous

Small molecule glutaminase inhibitors block glutamate release from stimulated microglia.

Numai utilizatorii înregistrați pot traduce articole

Glutaminase plays a critical role in the generation of glutamate, a key excitatory neurotransmitter in the CNS. Excess glutamate release from activated macrophages and microglia correlates with upregulated glutaminase suggesting a pathogenic role for glutaminase. Both glutaminase siRNA and small

Biological and molecular mechanisms of sulfur mustard analogue-induced toxicity in JB6 and HaCaT cells: possible role of ataxia telangiectasia-mutated/ataxia telangiectasia-Rad3-related cell cycle checkpoint pathway.

Numai utilizatorii înregistrați pot traduce articole

Effective medical treatment and preventive measures for chemical warfare agent sulfur mustard (HD)-caused incapacitating skin toxicity are lacking, because of limited knowledge of its mechanism of action. The proliferating basal epidermal cells are primary major sites of attack during HD-caused skin

Sodium pyruvate modulates cell death pathways in HaCaT keratinocytes exposed to half-mustard gas.

Numai utilizatorii înregistrați pot traduce articole

2-Chloroethyl ethyl sulfide (CEES) or half-mustard gas, a sulfur mustard (HD) analog, is a genotoxic agent that causes oxidative stress and induces both apoptotic and necrotic cell death. Sodium pyruvate induced a necrosis-to-apoptosis shift in HaCaT cells exposed to CEES levels ≤ 1.5 mmol/L and

Ultrastructural and histological effects of exposure to CEES or heat in a human epidermal model.

Numai utilizatorii înregistrați pot traduce articole

Ultrastructural and terminal deoxynucleotidyl transferase nick end labeling (TUNEL) studies were conducted to compare mechanisms of 2-chloroethyl ethyl sulfide (CEES) and heat-induced injury to EpiDerm. Twenty-two hours after 2-h exposure to the monofunctional alkylating agent CEES, budding of

Role of reactive nitrogen species generated via inducible nitric oxide synthase in vesicant-induced lung injury, inflammation and altered lung functioning.

Numai utilizatorii înregistrați pot traduce articole

Pulmonary toxicity induced by sulfur mustard and related vesicants is associated with oxidative stress. In the present studies we analyzed the role of reactive nitrogen species (RNS) generated via inducible nitric oxide synthase (iNOS) in lung injury and inflammation induced by vesicants using

Antioxidant liposomes protect against CEES-induced lung injury by decreasing SAF-1/MAZ-mediated inflammation in the guinea pig lung.

Numai utilizatorii înregistrați pot traduce articole

We reported earlier in a guinea pig model that exposure of 2-chloroethyl ethyl sulfide (CEES), a mustard gas analog, causes lung injury associated with the activation of tumor necrosis factor alpha (TNF-alpha), mitogen activated protein kinases (MAPK) signaling, and activator protein-1 (AP-1)

Mustard vesicating agent-induced toxicity in the skin tissue and silibinin as a potential countermeasure.

Numai utilizatorii înregistrați pot traduce articole

Exposure to the vesicating agents sulfur mustard (SM) and nitrogen mustard (NM) causes severe skin injury with delayed blistering. Depending upon the dose and time of their exposure, edema and erythema develop into blisters, ulceration, necrosis, desquamation, and pigmentation changes, which persist
