Objective: To investigate the effectiveness of high-dose corticosteroids in patients with severe leptospirosis, especially in reducing morbidity and mortality rates. Methods: Literature searches were conducted using PubMed and SCOPUS. One systematic review and one systematic review with meta-analysis were selected from three chosen studies. Results: The systematic review from Rodrigo et al. only included qualitative synthesis from four interventional studies. Early administration of methylprednisolone can be beneficial; however, low number and poor methodological quality of the studies question the validity of this review. Duggal et al. stated that there was no significant difference in the therapeutic effects of early high-dose corticosteroids (P ? 0.05; 95% CI: 0.81?1.37), early low-dose corticosteroids (P ? 0.05; 95% CI: 0.3?1.03), and late low-dose corticosteroids (P ? 0.05; 95% CI: 0.11?2.52). Limited number of studies and high statistical heterogeneity, however, are major drawbacks for this review. Conclusion: Evidence about the role of high-dose corticosteroids in severe leptospirosis patients with pulmonary complications, especially their benefits, is still limited. Additional randomized, controlled trials with adequate statistical power still need to be conducted.

Endocrine therapy using estrogen receptor-alpha (ER-alpha) antagonists for attenuating horm2one-driven cell proliferation is a major treatment modality for breast cancers. To exploit any DNA repair deficiencies associated with endocrine therapy, we investigated the functional and physical interactions of ER-alpha with O6-methylguanine DNA methyltransferase (MGMT), a unique DNA repair protein that confers tumor resistance to various anticancer alkylating agents. The ER-alpha -positive breast cancer cell lines (MCF-7, T47D) and ER- negative cell lines (MDAMB- 468, MDAMB-231), and established inhibitors of ER-alpha and MGMT, namely, ICI-182,780 (Faslodex) and O6-benzylguanine, respectively, were used to study MGMT-ER interactions. The MGMT gene promoter was found to harbor one full and two half estrogen-responsive elements (EREs) and two antioxidant-responsive elements (AREs). MGMT expression was upregulated by estrogen, downregulated by tamoxifen in Western blot and promoter-linked reporter assays. Similarly, both transient and stable transfections of Nrf-2 (nuclear factor-erythroid 2-related factor-2) increased the levels of MGMT protein and activity 3 to 4-fold reflecting novel regulatory nodes for this drugresistance determinant. Of the different ER-alpha antagonists tested, the pure anti-estrogen fulvestrant was most potent in inhibiting the MGMTactivity in a dose, time and ER-alpha dependent manner, similar to O6-benzylguanine. Interestingly, fulvestrant exposure led to a degradation of both ER-alpha and MGMT proteins and O6-benzylguanine also induced a specific loss of ER-alpha and MGMT proteins in MCF-7 and T47D breast cancer cells with similar kinetics. Immunoprecipitation revealed a specific association of ER-alpha and MGMT proteins in breast cancer cells. Furthermore, silencing of MGMT gene expression triggered a decrease in the levels of both MGMT and ER-alpha proteins. The involvement of proteasome in the drug-induced degradation of both proteins was also demonstrated. Fulvestrant enhanced the cytotoxicity of MGMT-targeted alkylating agents, namely, temozolomide and BCNU by 3 to 4-fold in ER-alpha positive cells, but not in ER-negative cells.We conclude that MGMTand ER-alpha proteins exist as a complex and are co-targeted for ubiquitin-conjugation and subsequent proteasomal degradation. The findings offer a clear rationale for combining alkylating agents with endocrine therapy.

Alcohol-induced muscle damage (AIMD) is an umbrella term that includes all forms of alcoholic myopathy developing in acute or chronic alcohol intoxication. The most common form of destruction of skeletal muscles in alcoholism is chronic alcoholic myopathy, which develops independently of other alcohol-induced disorders, such as polyneuropathy, the malabsorption syndrome, and liver damage, but may be combined with them. The atrophy of muscle fibers underlies skeletal muscle destruction in chronic AIMD. Type II muscle fibers are affected to a greater degree than type I muscle fibers. To date, the pathogenesis of chronic alcoholic myopathy has been studied insufficiently. The imbalance between protein synthesis and proteolysis, as well as increased apoptosis rate, is discussed.

Chronic obstructive pulmonary disease (COPD) is the most prevalent obstructive lung disease worldwide characterized by decline in lung function. It is associated with airway obstruction, oxidative stress, chronic inflammation, mucus hypersecretion, and enhanced autophagy and cellular senescence. Cigarette smoke being the major risk factor, other secondary risk factors such as the exposure to air pollutants, occupational exposure to gases and fumes in developing countries, also contribute to the pathogenesis of COPD. Conventional therapeutic strategies of COPD are based on anti-oxidant and anti-inflamma-tory drugs. However, traditional anti-oxidant pharmacological therapies are commonly used to alleviate the impact of COPD as they have many associated repercussions such as low diffusion rate and inappropriate drug pharmacokinetics. Recent advances in nanotechnology and stem cell research have shed new light on the current treatment of chronic airway disease. This review is focused on some of the anti-oxidant therapies currently used in the treatment and management of COPD with more emphasis on the recent advances in nanotechnology-based therapeutics including stem cell and gene therapy approaches for the treatment of chronic airway disease such as COPD and asthma.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Critically ill patients in the intensive care unit (ICU) present with a variety of different pathologies, and mortality is high despite extensive multi-organ supportive treatment. Reactive oxygen species (ROS) are believed to play a pivotal role in the pathophysiology of organ dysfunction in the ICU. In particular, the role of ROS as a final common pathway of cell damage has been increasingly emphasised in the adult respiratory distress syndrome (ARDS), in central nervous system traumatic and hypoxic states, and as a cause of ischaemic neurological deficits after subarachnoid haemorrhage. Measurement of total antioxidant status (TAS) has shown improved survival of patients with high TAS and poorer outcomes for those with lower values. Attempts to supplement endogenous antioxidant defences have not demonstrated clear benefits in randomised clinical trials, and the use of free radical scavenging agents have had similar mixed results. Considering the wide variation in the nature and severity of illness in the intensive care population, it is not surprising that clear evidence of the efficacy of antioxidant therapies in improving survival has not been clearly demonstrated. However, single component therapies for complex pathophysiological processes are rarely successful, and the role of antioxidants in the critically ill should be thought of as only part of a rational and logical therapeutic approach.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Reference of 19771-63-2, you can also check out more blogs about19771-63-2

The proton-coupled amino acid transporter hPAT1 has recently gained much interest due to its ability to transport small drugs thereby allowing their oral administration. A three-dimensional quantitative structure-activity relationship (3D QSAR) study has been performed on its natural and synthetic substrates employing comparative molecular similarity indices analysis (CoMSIA) to investigate the structural requirements for substrates and to derive a predictive model that may be used for the design of new prodrugs. The cross-validated CoMSIA models have been derived from a training set of 40 compounds and the predictive ability of the resulting models has been evaluated against a test set of 10 compounds. Despite the relatively narrow range of binding affinities (Ki values) reliable statistical models with good predictive power have been obtained. The best CoMSIA model in terms of a proper balance of all statistical terms and the overall contribution of individual properties has been obtained by considering steric, hydrophobic, hydrogen bond donor and acceptor descriptors (q2 cv = 0.683, r2 = 0.958 and r2 PRED = 0.666). The 3D QSAR model provides insight in the interactions between substrates and hPAT1 on the molecular level and allows the prediction of affinity constants of new compounds. A pharmacophore model has been generated from the training set by means of the MOE (molecular operating environment) program. This model has been used as a query for virtual screening to retrieve potential new substrates from the small-molecule, ‘leadlike’ databases of MOE. The affinities of the compounds were predicted and 11 compounds were identified as possible high-affinity substrates. Two selected compounds strongly inhibited the hPAT mediated L-[3H]proline uptake into Caco-2 cells constitutively expressing the transport protein.
