Chagas Disease, Leishmaniasis, and Malaria in Solid Organ Transplant Recipients

Received: 28 October 2018;  Published: 15 January 2019;  doi: 10.21926/obm.transplant.1901039

Abstract

Solid organ transplantation (SOT) is increasingly employed worldwide to treat several diseases causing both acute and chronic organ failure. Recipients of SOT are at an increased risk to develop infections as a consequence of immunosuppressive therapy. Sometimes such infections may be acquired by the transplanted organ or by reactivation of a previously acquired latent infection. The globalization and the increase of international travel poses a risk for exposure to infections such as Chagas disease (CD), leishmani [...]

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 [...]

Deciphering the Epigenetic Landscape of Suicidal Behaviour: A Review of Current Findings, Caveats and Future Directions

Received: 20 June 2018;  Published: 06 October 2018;  doi: 10.21926/obm.genet.1804039

Abstract

Suicide is the second leading cause of death globally among young people and the tenth leading cause of death across all ages. Approximately 800,000 people die by suicide every year representing a significant global health burden. Despite this burden, the molecular pathology of suicide remains poorly understood. A number of recent studies have shown that epigenetic alterations are associated with suicidal behaviour. These epigenetic mechanisms, which act to regulate gene expression via modifications to DNA, histone [...]

Fructose Increases Uric Acid Contributing to Metabolic Syndrome - Herbal, Nutritional and Dietary Strategies to Reduce Uric Acid

Received: 09 July 2018;  Published: 28 September 2018;  doi: 10.21926/obm.icm.1803022

Abstract

The metabolism of fructose by the liver produces uric acid and elevated serum uric acid levels are an independent risk factor for hypertension, metabolic syndrome, and cardiovascular disease. Fructose occurs in fruits and fruit juices, honey as well as in the sweeteners sucrose (common white sugar) and High Fructose Corn Syrup (HFCS). Dietary fructose may be considered a naturally occurring toxin because it is largely metabolised by the liver with little fructose reaching the systemic blood circulation. Uric acid i [...]

Received: 27 June 2018;  Published: 27 September 2018;  doi: 10.21926/obm.icm.1803021

Abstract

St. John’s wort (SJW), or Hypericum perforatum, is a perennial herb that is used to treat depression in several countries. Based on the available evidence, it can be hypothesized that SJW would also have beneficial prophylactic and therapeutic effects in patients with metabolic syndrome. In this review, we summarize and discuss the best designed studies that have investigated the effects of SJW extract on adipocyte differentiation, the inflammatory process, and glucose metabolism, all of which are relevant to [...]

Thai Ethnomedicinal Plants Used for Diabetes Treatment

Received: 25 April 2018;  Published: 24 September 2018;  doi: 10.21926/obm.icm.1803020

Abstract

Background: Diabetes is a metabolic disorder and a serious global health problem. Over 400 million people suffer from diabetes and it is estimated that the number will dramatically increase in the future. The cost of diabetes treatment for individual patients is very high. However, traditional knowledge could be used to support conventional diabetes treatments. Here, we identify medicinal plants that have been used as treatments for diabetes based on Thai ethnobotanical knowledge. Methods: We present a literature r [...]

Ectopic Pelvic Kidney with Anomalous Vascular Supply during Deceased Organ Procurement – Case Report

Received: 13 August 2018;  Published: 21 September 2018;  doi: 10.21926/obm.transplant.1803020

Abstract

Even though renal ectopia is common, there have been very few reports of these kidneys being used for transplantation. The concerns with using such kidneys are subnormal function, ureteral anomalies and complications and anomalous arterial supply which makes arterial reconstruction challenging. Majority of reports are for use in living donor transplantation where good preoperative imaging is available. There is very scant literature reporting use of ectopic pelvic kidneys from deceased donors. We report a case of a [...]

Contribution of PET Imaging to Clinical Management of Gliomas

Received: 02 July 2018;  Published: 19 September 2018;  doi: 10.21926/obm.neurobiol.1803011

Abstract

Gliomas originating from glial cells comprise about 30% of all primary central nervous system tumors and 80% of malignant brain tumors. Gliomas differ in their biological activity and are categorized according to grades, from benign to malignant with high recurrence rates. For diagnosis, location and extent of the tumor is assessed by CT and MRI, but for grading, additional parameters are necessary: contrast enhanced CT and MRI reveal damage of the blood–brain barrier, perfusion-weighted MRI shows regional blood su [...]

Histone O-GlcNAcylation and Potential Biological Functions

Received: 05 July 2018;  Published: 17 September 2018;  doi: 10.21926/obm.genet.1803036

Abstract

Histone modifications play an important role in the control of DNA-based processes by altering the structure and function of chromatin. O-linked N-acetylglucosamine (O-GlcNAc) modification is a form of post-translational modification of proteins that affects the serine (Ser)/threonine (Thr) residues. This process is controlled by a single pair of enzymes, i.e. O-GlcNAc transferase (OGT) and O-GlcNAcase (OGA). Recent evidence indicates the existence of O-GlcNAc modification of histones, with 16 histone O-GlcNAc site [...]

Introduction to the Special Issue on Next Generation Sequencing: Short General Overview of NGS

Received: 14 August 2018;  Published: 13 September 2018;  doi: 10.21926/obm.genet.1803034

Abstract

he publication of the double helix DNA structure in 1953 [1] was the kick-off of numerous efforts to understand and unravel the complexity of the human genome. It took 50 years until the human genome project, based on Sanger sequencing, was completed in 2003 [2]. This was followed by what may be considered a revolution in the field of DNA analysis: the introduction of Next Generation Sequencing (NGS) in 2005 consisting of massively parallel sequencing of DNA fragments which allows the high throughput analysis of la [...]
