Emerging evidence suggests that thiazole compounds are of great interest due to their protective effect against DM. Protective effects of thiazole derivatives against hyperglycemia have been demonstrated in earlier in vitro and in vivo studies. Previously, anti-oxidant and free radical scavenging activities of 2-(4-Fluorobenzamido)-4-methylthiazole-5-carboxylicacid, a newly developed thiazole derivative (NDTD), have been well-documented. Current study investigated the pharmacological effect of NDTD on hyperglycaemia, insulin sensitivity, lipid profile, anti-inflammatory and oxidative stress markers in an animal model...

The thyroid hormone (TH) analog eprotirome (KB2115; 3-[[3,5-dibromo-4-[4-hydroxy-3-(1-methylethyl)-phenoxy]-phenyl]-amino]-3-oxopropanoic acid) was developed to lower cholesterol through selective activation of the T3 receptor isoform TRβ1 in the liver. Interestingly, eprotirome shows low uptake in non-hepatic tissues, explaining its lipid-lowering action without adverse extra-hepatic thyromimetic effects. Clinical trials have shown marked decreases in serum cholesterol levels.We explored the transport of eprotirome across the plasma membrane by members of three TH transporter families: monocarboxylate transporters MCT8 and 10, Na-independent organic anion transporters OATP1A2, 1B1, 1B3, 1C1, 2A1 and 2B1, and Na-dependent organic anion transporters SLC10A1-7...

Cadmium (Cd) is a highly toxic and widely distributed heavy metal that induces various diseases in humans through environmental exposure. Therefore, alleviation of Cd-induced toxicity in living organisms is necessary. In this study, we investigated the protective role of sulforaphane on Cd-induced toxicity in human peripheral blood lymphocytes and monocytes. Sulforaphane did not show any major reduction in the viability of lymphocytes and monocytes. However, Cd treatment at a concentration of 50μM induced around 69% cell death...

Synthetic pentlandite (Fe4.5Ni4.5S8) is a promising electrocatalyst for hydrogen evolution, demonstrating high current densities, low overpotential and remarkable stability in bulk form. The depletion of sulfur from the surface of this catalyst during the electrochemical reaction has been proposed to be beneficial for its catalytic performance, but the role of sulfur vacancies and the mechanism determining the reaction kinetics are still unknown. We have performed electrochemical operando studies of the vibrational dynamics of pentlandite under hydrogen evolution reaction conditions using 57Fe nuclear resonant inelastic X-ray scattering...

Human chorionic gonadotropin (hCG) is produced primarily by differentiated syncytiotrophoblasts, and represents a key embryonic signal that is essential for the maintenance of pregnancy. hCG can activate various signaling cascades including mothers against decapentaplegic homolog 2 (Smad2), protein kinase C (PKC), and/or protein kinase A (PKA) in several cells types by binding to luteinizing hormone/chorionic gonadotropin receptor (LHCGR) or potentially by direct/indirect interaction with transforming growth factor beta receptor (TGFβR)...

Due to a very large number of connected virtual objects in the surrounding environment, intelligent service features in the Internet of Things requires the reuse of existing virtual objects and composite virtual objects. If a new virtual object is created for each new service request, then the number of virtual object would increase exponentially. The Web of Objects applies the principle of service modularity in terms of virtual objects and composite virtual objects. Service modularity is a key concept in the Web Objects-Enabled Internet of Things (IoT) environment which allows for the reuse of existing virtual objects and composite virtual objects in heterogeneous ontologies...

Acute lung injury (ALI) is associated with deterioration of alveolar-capillary lining and transmigration and activation of inflammatory cells. Whereas a selective phosphodiesterase-4 (PDE4) inhibitor roflumilast has exerted potent anti-inflammatory properties, this study evaluated if its intravenous delivery can influence inflammation, edema formation, and respiratory parameters in rabbits with a lavage-induced model of ALI. ALI was induced by repetitive saline lung lavage (30 ml/kg). Animals were divided into 3 groups: ALI without therapy (ALI), ALI treated with roflumilast i...

The respiratory system is constantly exposed to pathogens which enter the lungs by inhalation or via blood stream. Lipopolysaccharide (LPS), also named endotoxin, can reach the airspaces as the major component of the outer membrane of Gram-negative bacteria, and lead to local inflammation and systemic toxicity. LPS affects alveolar type II (ATII) cells and pulmonary surfactant and although surfactant molecule has the effective protective mechanisms, excessive amount of LPS interacts with surfactant film and leads to its inactivation...

Mycophenolate mofetil (MMF) is used extensively for the induction therapy of lupus nephritis (LN) and has even outpaced intravenous (i.v.) cyclophosphamide (CyP) as the initial choice of therapy. There are no studies comparing the response of MMF with standard dose i.v. CyP in Indian patients with LN. We conducted a 24-week prospective, randomized, open-label trial comparing oral MMF with monthly i.v. CyP as induction therapy for active biopsy proven Class III and IV LN. The primary end-point was response to treatment at 24 weeks, and the secondary end-points were complete remission, Systemic Lupus Erythematosus Disease Activity Index scores (SLEDAI) and adverse reactions...
