Although isoniazid also degrades partially, but its degradation is reversible. OBJECTIVE Presently we provide a proof of the fact that the simultaneous oral administration of rifampicin (RIF), upon incorporation into solid lipid nanoparticles (RIF-SLNs), with isoniazid (INH) overcomes its INH-induced degradation and improves its oral bioavailability in rats. METHODS Solid lipid nanoparticles of RIF (RIF-SLNs) were prepared using a novel and patented method. The effect of INH was investigated on in vivo bioavailability of RIF both in its free and encapsulated (RIF-SLNs) form, after oral administration to rats. RESULTS Cmax and AUC0-∞ of RIF increased 158 % and 125 %, respectively, upon incorporation into SLNs versus free RIF when combined with INH. The Tmax decreased from 5.67 h to 3.3 h, and plasma concentration of RIF remained above its MIC (8 µg/ml) at all the tested time points starting with 15 min, when administered as RIF-SLNs in combination with INH. CONCLUSIONS Results confirm the scope of combining RIF-SLNs with INH to overcome bioavailability of free RIF when combined with INH especially in fixed dose combinations.

BACKGROUND It has been reported that increased levels of AGEs are observed in patients with preeclampsia as compared with healthy pregnant subjects, which was mainly associated with oxidative stress and inflammation. Besides, in women with preeclampsia, there are metabolic changes such as hyperinsulinemia, glucose intolerance, dyslipidemia, among others, that are associated with an exacerbated insulin resistance. Additionally, some parameters indicate the alteration of hepatic function, such as increased levels of liver enzymes. However, the relationship of levels of AGEs with altered lipidic, hepatic and glucose metabolism parameters in preeclampsia has not been evaluated. OBJECTIV, circulating levels of AGEs were higher in patients with preeclampsia than those observed in healthy pregnant subjects. Besides, variables of hepatic and metabolic profile, particularly those related to insulin resistance, were higher in preeclampsia as compared with healthy pregnant subjects. Interestingly, there is a positive correlation between AGEs levels and insulin resistance. CONCLUSIONS Circulating levels of AGEs were higher in patients with preeclampsia than those observed in healthy pregnant subjects. Besides, hepatic and metabolic profiles, particularly those related to insulin resistance, were higher in preeclampsia as compared with healthy pregnant subjects. Interestingly, there is a positive correlation between AGEs levels and insulin resistance, suggesting that excessive glycation and an impaired metabolic profile contribute to the physiopathology of preeclampsia.

METHODS A total of fifty male Sprague Dawley rats were randomly divided into five groups (10 rats per group) sham operation (SHAM) control group, bile duct ligation (BDL) model group, low-dose carvedilol treatment group (0.1mg•kg-1•d-1), medium-dose carvedilol treatment group (1mg•kg-1•d-1), and high-dose carvedilol treatment group (10mg•kg-1•d-1). Rat hepatic fibrosis model was established by applying BDL. Forty-eight hours after the operation, carvedilol was administered twice a day. The blood and liver were simultaneously collected under the aseptic condition for further detection in two weeks after operation. The alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil) and albumin (Alb) in seg pathway, thus playing a potential therapeutic role in cholestatic liver fibrosis.

BACKGROUND The correlation between asbestiform fibers, lung cancer, pleural mesothelioma and other lung diseases is already well established as the pathophisiological respiratory mechanisms involved by inhalation of Fluoro-edenite (FE). The latter is represented by cell proliferation and inducing release of growth factors, cytokines and reactive oxygen and nitrite species, with DNA damage that cause chronic inflammation and carcinogenesis. LY2603618 price MacroH2A.1, and histone variant, seems to play a role in sensing the metabolic state of the cell and linking it with chromatin. Physiologically, MacroH2A.1 is expressed at low levels in stem cells and it became upregulated during differentiation, preventing reprogramming of induced pluripotent stem cells and after nuclear transfer. In particular, MacroH2A.1 has been shown to explicate a potent antitumor mechanism in vivo as it results upregulated in senescent cells determining a permanent growth-arrest. OBJECTIVE Evaluate the possible role the histone variant in the organism response to deep insight the mechanisms of toxicity and the cellular response to FE. METHODS Lung and lymph nodes of exposed sheep were selected. Samples were processed for histological and immunihistochemical evaluations. Densitometric, morphometric and statistical analysis were conducted. RESULTS Tissue sections of FE exposed sheep demonstrated an overexpression of MacroH2A.1 vs unexposed samples. The data suggest an involvement of these molecule in the cellular response triggered by FE directed exposure. CONCLUSION In this contest, MacroH2A.1 overexpression supports its function as an epigenetic stabilizer that helps to establish and maintain differentiated states.
