Birth Tissue-Derived Mesenchymal Stromal/Stem Cell Isolation and Assessment

Received: 25 September 2019;  Published: 09 June 2020;  doi: 10.21926/obm.transplant.2002112

Abstract

Mesenchymal Stromal/Stem Cells (MSCs) were originally discovered in the 1970s. MSCs are considered a multipotent population that retain tri-lineage differentiation. These cells can be sourced from a variety of tissues, including bone marrow, adipose, molar pulp, and birth tissues. Historically varying definitions of MSCs have existed, but in 2006, the International Society for Cellular Therapy (ISCT) set forth a standardized, minimal criteria for MSCs, including plastic adherence, differentiation into osteoblasts, [...]

Intermittent Fasting and Brain Health: Efficacy and Potential Mechanisms of Action

Received: 15 March 2020;  Published: 01 June 2020;  doi: 10.21926/obm.geriatr.2002121

Abstract

Despite continuous efforts to combat neurodegenerative diseases, researchers have been unable to find an intervention that reverses degeneration and/or improves cognition in dementia or healthy aging. Therefore, it is considerably important to identify lifestyle factors that could potentially aid in healthy brain aging and prevent or delay neurodegenerative diseases. The emerging interest in the ancient practice of fasting has inclined researchers to study the physiological and behavioral effects of this practice. [...]

Dynamic Functional Connectivity Fading Analysis and Classification of Alzheimer’s Disease, Mild Cognitive Impairment and Normal Control Subjects based on Resting-State fMRI Data

Received: 29 September 2019;  Published: 01 June 2020;  doi: 10.21926/obm.neurobiol.2002059

Abstract

In this paper, motivated by the fading effect in wireless communications, where severe channel fading is related to information loss during the transmission, we evaluate and analyze the fading effect in time-varying functional connectivity of AD, MCI and NC subjects based on the resting-state fMRI data, and then apply that for AD, MCI, NC classification. We show that in some critical brain regions, compared with NC subjects, AD subjects suffer more severe and long lasting fading in the functional connectivity level [...]

Splicing HAC1/XBP1 mRNAs in Cytoplasm: The Non-Conventional mRNA Splicing Reaction in the Unfolded Protein Response

Received: 23 March 2020;  Published: 22 May 2020;  doi: 10.21926/obm.genet.2002110

Abstract

The majority of the secretory and transmembrane proteins are folded in the endoplasmic reticulum (ER). When unfolded proteins accumulate in the ER, a collective of signalling pathways, termed the unfolded protein response (UPR), are activated to restore the ER protein folding homeostasis. The most evolutionarily conserved branch of UPR is mediated by the kinase/endoribonuclease Ire1. Ire1 mediates a cytosolic non-conventional mRNA splicing reaction of HAC1 mRNA in yeast and XBP1 mRNA in mammalian cells. The spliced [...]

Using Additives to Control the Decomposition Temperature of Sodium Borohydride

Received: 20 April 2020;  Published: 19 May 2020;  doi: 10.21926/jept.2002009

Abstract

Hydrogen (H2) shows great promise as zero-carbon emission fuel, but there are several challenges to overcome in regards to storage and transportation to make it a more universal energy solution. Gaseous hydrogen requires high pressures and large volume tanks while storage of liquid hydrogen requires cryogenic temperatures; neither option is ideal due to cost and the hazards involved. Storage in the solid state presents an attractive alternative, and can meet the U.S. Department of Energy (DOE) constraints to find m [...]

Multidrug-Resistant Bacterial Infections before and after Liver Transplantation

Received: 29 March 2020;  Published: 18 May 2020;  doi: 10.21926/obm.transplant.2002110

Abstract

Bacterial infection represents a common event in the natural history of cirrhosis, especially in patients with end-stage liver disease. An episode of bacterial infection may significantly modify a patient’s outcome in the setting of liver transplantation (LT) by impairing hepatic and extrahepatic organ functions, both in pre-operative and post-operative phases. Infections caused by multidrug-resistant organisms (MDRO) are increasing in cirrhosis due to high antibiotic exposure and hospitalizations. This issue is pa [...]

The Use of Biomaterials in Internal Radiation Therapy

Received: 18 March 2020;  Published: 12 May 2020;  doi: 10.21926/rpm.2002012

Abstract

Radiotherapy has become one of the most prominent and effective modalities for cancer treatment and care. Ionising radiation, delivered either from external or internal sources, can be targeted to cancerous cells causing damage to DNA that can induce apoptosis. External beam radiotherapy delivers either photon radiation (x-rays or gamma rays) or particle radiation (neutrons or protons) in a targeted manner to specific tumour locations. Internal radiotherapy involves placing radioactive sources within the body to de [...]
