RESUMEN
@#Worldwide morbidity and mortality of acute myocardial infarction (AMI) and related heart failure are still high.While effective early reperfusion of the criminal coronary artery after a confirmed AMI is the typical and effective treatment at present, collateral myocardial ischemia reperfusion injury (MIRI) and pertinent cardio-protection are still challenging to address and have inadequately understood mechanisms.One important reason might be that AMI is multifactorial, causing cardiomyocyte death via multiple mechanisms, as well as affecting other cell types, including platelets, fibroblasts, endothelial and smooth muscle cells, and immune cells.Many cardioprotective strategies act through common end-effectors and may be suboptimal in patients with comorbidities.Therefore, unveiling the related multitarget strategies participating in triggering and resisting the pathobiology of MIRI is a promising and valuable frontier.The review specifically focuses on the recent MIRI advances that are supported by multitarget strategies and new targets under development in order to bring the rational combination of multitarget therapies up to date, as well as to identify findings that may facilitate the new drug of novel targets.
RESUMEN
@#MicroRNAs are short non-coding RNAs that regulate and control the translation of target genes, and play an important role in gene expression involved in the development of spinal cord and spinal cord injury, which constitute novel targets for therapeutic intervention to promote repair and regeneration of the spinal cord, also they are the potential biomarkers of spinal cord injury. This article reviewed the mechanism of microRNAs and listed several microRNAs in spinal cord injury area.
RESUMEN
New progress of guidelines for novel targets to iron overload in the 56th American Society of Hematology (ASH) annual meeting was reviewed.β-thalassemia and hereditary hemochromatosis disorders,and inappropriately low levels of the liver hormone hepcidin are responsible for the increased iron absorption,leading to toxic iron accumulation in many organs.Several studies have shown that targeting iron absorption could be beneficial to reducing or preventing iron overload in these 2 disorders.New approaches target Tmprss6.Additional strategies in β-thalassemia are showing beneficial effects in ameliorating ineffective erythropoiesis and anemia.The goal of this review is to discuss the major factors controlling iron metabolism and erythropoiesis and to discuss potential novel therapeutic approaches to reduce or prevent iron overload in these 2 disorders and ameliorate anemia in β-thalassemia.
RESUMEN
Hepatitis C infection represents a major global public health problem; as it leads to significant morbidity, mortality, and financial burden on healthcare system. According to world health organization, nearly 2- 3% (130-170 million) of the world’s population has been infected with hepatitis C. The current standard therapy is limited both in efficacy and tolerability which highlights the large unmet medical need in this area. Recent advances in the understanding of lifecycle of hepatitis C virus and host cell interactions have led to the identification of multiple novel antiviral targets. Intense research effort is currently being directed towards translating these targets into developing more efficacious and safe treatment options for patients living with HCV infection. Current review aims to discuss the emerging therapies in pipeline for chronic hepatitis C outlining their mode of action and current stage of development in clinical trials.
