A is for Autophagy and Alzheimer's

Received: 01 August 2018;  Published: 25 November 2018;  doi: 10.21926/obm.geriatr.1804020

Abstract

Improved understanding of the underlying cellular dysfunction and resultant neuropathology of sporadic Alzheimer’s disease (AD) is needed to stem the anticipated public health crisis due to this increasingly common neurodegenerative disease. The four main risk factors for sporadic AD are age, female gender, genetic carriage of the APOE4 allele and type two diabetes mellitus (T2DM). Each of these four risk factors is associated with impaired and/or dysfunctional autophagy suggesting that perturbation of autophagy is [...]

The Conundrum of High Body Mass Index in Kidney Transplant Patients

Received: 19 October 2018;  Published: 19 November 2018;  doi: 10.21926/obm.transplant.1804026

Abstract

Obesity is on the rise and the number of end stage renal disease patients who are obese parallel this trend. There is no universally accepted guideline for wait-listing end stage renal disease obese patients in order to reduce surgical complications and improve survival of the kidney graft. Criteria for acceptance are variable among transplant centres, as do post-transplant policies. Careful risk assessment to maximise the benefits of the limited organ donor resource must be undertaken prior to waitlist an obese ki [...]

TTF-1-Expressing Supratentorial Embryonal Tumors (PNET): A Clinicopathologic Study of Two Cases and Literature Review of TTF-1-Positive Primary Brain Tumors

Received: 07 October 2018;  Published: 14 November 2018;  doi: 10.21926/obm.neurobiol.1804016

Abstract

Thyroid transcription factor 1 (TTF-1) is a nuclear polypeptide and a tissue-restricted member of the homeobox protein family that, when attached to DNA, plays a crucial role in regulating the expression of select genes during early embryonic development of the thyroid, lung, and brain. As often happens, the initial enthusiasm for the diagnostic value of TTF-1 as a selective immunohistochemical marker of lung and thyroid tumors began to dwindle, due to its detection in tumors arising from other organs. TTF-1-expres [...]

The Concerted Action of Multiple Mechanisms to Induce and Sustain Transplant Tolerance

Received: 25 September 2018;  Published: 09 November 2018;  doi: 10.21926/obm.transplant.1804025

Abstract

Transplant tolerance has been achieved in experimental models using immune intervention strategies. Yet, their clinical translation remains unsuccessful and requires further optimization of immunotherapeutic regimens based on a deeper understanding of the cellular and molecular mechanisms at play in the induction and maintenance phases of immune tolerance. Intensive investigations have shed light on the tolerogenic networks underlying graft survival and have unraveled their complexity, which may depend on several p [...]

Received: 17 July 2018;  Published: 08 November 2018;  doi: 10.21926/obm.icm.1804029

Abstract

What is meditation? A tool that empowers you to create your life through working it from inside out, beginning with a thought. There is a story. A father had two sons: one felt a victim of life. He viewed his life through the prism of “My childhood was difficult. My father was an alcoholic. The reason my life is failing is because of that. I was not loved enough.” This is his inner mantra – a cycle of a repetitive thought patterns that he continuously told himself. His life followed that very mantra. He didn’t try [...]

Epigenetic Regulation by Androgen Receptor in Prostate Cancer

Received: 26 May 2018;  Published: 02 November 2018;  doi: 10.21926/obm.genet.1804047

Abstract

Prostate cancer is the most common cancer among men in the world. Androgen receptor (AR), acting as a nuclear receptor, facilitates ligand-dependent transcriptional activation in the nucleus. Androgen deprivation therapy (ADT) is used for the treatment of advanced prostate cancer because androgen and AR signaling drive prostate tumor growth and anti-apoptotic function. Resistance to ADT in most tumors develops quickly; thus, AR continues to be active in relapsed tumors called castration-resistant prostate cancer (C [...]
