Mild traumatic brain injury (mTBI) or concussion represents the majority of brain trauma in the United States. The pathophysiology of mTBI is complex and may include both focal and diffuse injury patterns. In addition to altered circuit dysfunction and traumatic axonal injury (TAI), chronic

Classical swine fever virus (CSFV)-macrophage interactions during infection were analysed by examining macrophage transcriptional responses via microarray. Eleven genes had increased mRNA levels (>2.5-fold, P<0.05) in infected cell cultures, including arginase-1, an inhibitor of nitric oxide

Coxiella burnetii is an obligate intracellular bacterium, responsible for Q fever, which survives in macrophages by interfering with their microbicidal competence. As functional polarization of macrophages is critical for their microbicidal activity, we studied the activation program of

Severe fever with thrombocytopenia syndrome (SFTS) caused by a recently identified bunyavirus, SFTSV, is an emerging infectious disease with extensive geographical distribution and high mortality. Progressive viral replication and severe thrombocytopenia are key features of SFTSV infection and fatal

Interleukin (IL)-10 increases host susceptibility to microorganisms and is involved in intracellular persistence of bacterial pathogens. IL-10 is associated with chronic Q fever, an infectious disease due to the intracellular bacterium Coxiella burnetii. Nevertheless, accurate animal models of

Q fever is caused by Coxiella burnetii, a bacterium that survives in MPhi. Vanin-1 is a membrane-anchored pantetheinase that controls tissue inflammation. Consequently, Vanin-1-deficient mice represent a unique mouse model in which stress-induced inflammation is limited by the reaction of resident

Functional constitutive nitric oxide synthase (NOS) is required for full expression of reflex cutaneous vasodilation that is attenuated in aged skin. Both the essential cofactor tetrahydrobiopterin (BH(4)) and adequate substrate concentrations are necessary for the functional synthesis of nitric

No comparative studies have addressed the oxidant and antioxidant states of blood and cerebrospinal fluid. To reveal this differential state, the study was designed to identify the seizure type with the worse prognosis by determining erythrocyte arginase and erythrocyte catalase, plasma and

We have demonstrated that therapeutic administration of L-arginine (L-arg) (120 mg/kg) at +2 h of whole body hyperthermia (WBH) could rescue the mice from heatstroke-induced death. Studies were undertaken to elucidate the role of L-arg in the immunomodulation of the heat-stressed mice.

A zoonotic pathogen, Brucella spp. is the causative agent of brucellosis, which results in abortion and loss in milk production in domestic animals, and undulant fever, osteoarticular pain and splenomegaly in humans. Due to the capability of the bacteria to modulate the host cell functions and

Visceral leishmaniasis (VL), caused by infection with the intracellular protozoan Leishmania donovani, is a chronic progressive disease with a relentlessly increasing parasite burden in the spleen, liver and bone marrow. The disease is characterized by fever, splenomegaly, cachexia, and

UNASSIGNED Dengue can cause increased vascular permeability that may lead to hypovolemic shock. Endothelial dysfunction may underlie this; however, the association of endothelial nitric oxide (NO) pathways with disease severity is unknown. UNASSIGNED We performed a prospective observational study in
