The Goal of Kidney Rejuvenation

The authors of this open access paper review the aging of the kidney and consider the prospects for using factors from young blood as a means of rejuvenation. This is a fairly narrow view, as there are many other approaches that should produce rejuvenation of the aged kidney, ranging from those close to realization, such as senolytic therapies to clear senescent cells, or various approaches to stem cell therapy, to those yet to be achieved, meaning much of the rest of the SENS agenda of rejuvenation biotechnologies to repair the damage that causes aging. Nonetheless, after so many years of trying to persuade the research community to open up on the topic of addressing the mechanisms of aging as a means of therapy, it is very pleasant to see so many publications in the literature doing just that. The present open discourse is a sea change in comparison to the silence of a decade or two ago, in which few researchers were willing to speak in public about treating aging. The science was always valid and promising, it is the culture that has changed for the better. It is well established that aging is associated with structural and functional renal changes. With the possible exception of the lung, the changes in kidney function with normal aging are the most dramatic of any human organ or organ system. The normal kidney loses about 25% of its mass during aging, with the loss involving both cortical glomeruli and tubules. Functionally, the aging kidney has a parallel decli...

Menon, Herbert Mössler, Hari Shanker SharmaAbstractThere is a growing trend of hypertension among military and civilian populations due to lifetime stressful situations. If hypertension is uncontrolled it leads to development of diabetes and serious neurological complications. Most of the World populations live in temperate zone across the World. Thus, a possibility exists that these hypertensive and diabetic people may have external heat as potential risk ...

Authors: Catho G, Huttner BD Abstract Introduction: Among the multidrug resistant pathogens, extended-spectrum beta-lactamase (ESBL-E) or carbapenemase-producing Enterobacteriaceae (CPE) are currently considered the main threat due to the scarcity of therapeutic options and their rapid spread around the globe. In addition to developing new antibiotics and stopping transmission, recent research has focused on "decolonization" strategies to eradicate the carriage of ESBL-E/CPE before infection occurs. Areas covered: In this narrative review, we aim to describe the current evidence of decolonization strategi...

Abstract A significant obstacle to the study of human cancer biology and the testing of human specific immunotherapeutics is the paucity of translational models that recapitulate both the growth of human tumors and the functionality of human immune systems. Humanized mice engrafted with human hematopoietic stem cells (HSC) and patient-derived xenografts (PDX) enable preclinical investigation of the interactions between the human immune system and human cancer. We use immunodeficient non-obese diabetic (NOD, scid, gamma) NSG™ or NSG™-SGM3 mice as hosts for establishment of human immunity following HSC i...

Abstract Experimental animal tumor models have been broadly used to evaluate anticancer drugs in the preclinical setting. They have also been widely applied for drug target discovery and validation, which usually follows four experimental strategies: first, assess the roles of putative drug targets using in vivo tumorigenicity and tumor growth kinetics assays of transplanted tumors, engineered through gain-of-function (GOF) by overexpressing transgene or knock-in (KI) or loss-of-function by gene silencing using knockdown (KD) or knockout (KO) or mutation via mutagenesis procedures; second, similarly genetically en...

Abstract The discovery of neural stem cells (NSCs) in the mammalian brain has raised many expectations as these unique cells might recapitulate different neurological diseases, including brain tumors, both from a functional and molecular perspective. Proper in vitro culturing of NSCs has emerged as a critical methodological issue, given that it should preserve the in vivo features of NSCs, with particular emphasis on cell heterogeneity. At the same time, the methodology for NSC culturing should allow the production of large amounts of cells to be exploited not only for prospective clinical applications but also fo...

Authors: Pierri F, Dufour C Abstract Introduction: About 60% of aplastic anemia (AA) patients are in need of further treatment after front line standard immunosuppressive therapy (IST). This along with the prolonged survival of AA subjects who do not respond to or relapse after this treatment makes management of these patients a rising and very challenging issue. Areas Covered: Literature research, carried out from the most commonly used data bases, included the following key words: aplastic anemia, immunosuppressive treatment, Anti Thymocyte Globuline, Ciclosporine A, refractory aplastic anemia, relapsing aplastic...

In this study, we determine whether transient reintroduction of embryonic stem cell cycle miR-294 promotes cardiomyocyte cell cycle reentry enhancing cardiac repair after myocardial injury. A doxycycline-inducible AAV9-miR-294 vector was delivered to mice for activating miR-294 in myocytes for 14 days continuously after myocardial infarction. miR-294-treated mice significantly improved left ventricular functions together with decreased infarct size and apoptosis 8 weeks after MI. Myocyte cell cycle reentry increased in miR-294 hearts parallel to increased small myocyte number in the heart. Isolated adult myocytes from miR-...

We report that the disruption of excitation-contraction coupling contributes to impaired force generation in the mouse model of Sod1 deficiency. Briefly, we found a significant reduction in sarcoplasmic reticulum Ca2+ ATPase (SERCA) activity as well as reduced expression of proteins involved in calcium release and force generation. Another potential factor involved in EC uncoupling in Sod1-/- mice is oxidative damage to proteins involved in the contractile response. In summary, this study provides strong support for the coupling between increased oxidative stress and disruption of cellular excitation contraction mac...

Conclusion: there is no increased risk of doing the lymph node dissection early on.   Dr. Eggener-CON   Basics Lymph node dissections rarely done, even for large tumors, because there is no proven therapeutic or staging benefit for low risk patients.  A Mayo study revealed no data showing therapeutic benefit in high risk patients.  For clinically node negative high risk patients, there is staging value but no proven therapeutic benefit. Rate of positive nodes is associated with stage and grade; the higher the stage and grade, the more likely there will be positive nod...
