Sporadic and Hereditary Hemangioblastoma: The Role of Endothelial Cells

Received: 26 November 2018;  Published: 04 March 2019;  doi: 10.21926/obm.neurobiol.1901021

Abstract

Hemangioblastomas (HBs) are benign, highly vascularized tumors of the central nervous system. Approximately 75% of HBs are sporadic, while 25% are associated with von Hippel–Lindau (VHL) disease. HBs consist of two main components: a rich capillary network composed of vascular endothelia and pericytes, within large vacuolated stromal cells, which harbor the genetic defect. The mechanism by which the VHL gene product (pVHL) causes HB is not completely clear. Wild-type pVHL is involved in the response to hypoxia, tar [...]

Dietary Modulation of the Gut Microbiome in Inflammatory Bowel Disease

Received: 28 April 2022;  Published: 09 August 2022;  doi: 10.21926/rpn.2203019

Abstract

Inflammatory bowel disease (IBD), which includes ulcerative colitis, and Crohn’s disease, is a chronic relapsing-remitting inflammatory state of the gastrointestinal (GI) system. The cause of IBD is multifactorial, encompassing factors of genetics, environment, and the host immune system, initiating a complex interplay of maladaptive host immune responses and subsequent chronic inflammation. Aberrant host immune responses are at least in part due to changes in the commensal microbiome, which can in turn affect the [...]

Recruiting Perinatal Fathers to Interventions and Research: A Conceptual Model of Engagement and Integrative Review of Barriers Encountered and Strategies Used

Received: 31 May 2022;  Published: 14 September 2022;  doi: 10.21926/obm.icm.2203041

Abstract

The perinatal period represents a unique developmental window for families and an opportunity to reach and engage fathers in research and preventive interventions. The distinctiveness of this period stems from the changes and stressors that parents experience which affect their openness to enroll in interventions (e.g., adaptive parenting, physical and mental health, relationship skills, and economic self-sufficiency) and participate in research. While long understudied, paternal research in the perinatal period ha [...]

A Combined Power and Ejector Refrigeration Cycle System for Thermal Energy Recovery from the Waste Heat of Internal Combustion Engine

Received: 31 December 2022;  Published: 06 February 2023;  doi: 10.21926/jept.2301006

Abstract

In this paper, due to the importance of energy recovery from internal combustion engines and the increasing human growing need for power and refrigeration, a two-cycle power and refrigeration system consisting of an organic Rankine cycle and an ejector refrigeration cycle is investigated analytically. The proposed system with the ability to use the ejector as an effective and economical system, can produce simultaneous power and refrigeration by drawing thermal energy from the exhaust gas and engine coolant in the [...]

Dearomatization of the Kerosene Fraction: Kinetic Studies

Received: 09 January 2022;  Published: 28 June 2022;  doi: 10.21926/cr.2202017

Abstract

The kinetics of dearomatization of a kerosene fraction processed using a zeolite catalyst (0.9 HZSM-5) at different temperatures (160-200°C), the molar ratio between the aromatic hydrocarbons present in the kerosene fraction and n-decene (1:(0.5-4)), and the reaction time (1-3 h) were studied. Based on the obtained data, a kinetic model for kerosene dearomatization is proposed. It is assumed that the single-center Riedel mechanism is followed. The stage associated with the interaction between n-decene adsorbed on t [...]

Molecular Basis of Allogeneic Pluripotent Stem Cell Treatment of a Patient with Sporadic ALS

Received: 21 August 2020;  Published: 29 March 2021;  doi: 10.21926/obm.geriatr.2101164

Abstract

There are no curative strategies for ALS, and as a result the alternative therapies are gaining ground, in particular the stem cell-based therapies which hold a promising future. Here we describe an ALS patient, who by choice, received allogeneic human cord-blood derived multipotent stem cells (MSC) intravenously and intrathecally. This is the first snapshot of pre-and post-stem cell transplantation in an ALS patient through transcriptomic, epigenomic, and proteomic follow-up elucidating the effect of stem cells in [...]

Single-Case Neuropsychological Assessment of a Patient with a Posterior Parietal Lesion Using Behavioral Testing and Resting-State fMRI

Received: 29 January 2021;  Published: 24 August 2021;  doi: 10.21926/obm.neurobiol.2103105

Abstract

This study integrated functional connectivity measures using resting-state fMRI and behavioral data from a single-case observation of patient (PER) one year after right-hemispheric hemorrhage in the intraparietal sulcus and superior parietal lobule (IPS/SPL). PER showed no sign of clinical neglect. Her behavioral performance in the visuo-manual pointing task and in the letter discrimination task under conditions of endogenous and exogenous attentional cueing was compared between the left (affected) and right (unaff [...]
