Ocular Pressure-Volume Relationship and Ganglion Cell Death in Glaucoma

Received: 24 November 2020;  Published: 21 May 2021;  doi: 10.21926/obm.neurobiol.2102098

Abstract

We studied how GC death in glaucoma related to the intraocular pressure (IOP), eyeball volume (VS) and elasticity (volumetric KS and tensile ES), and eyeball volume-pressure relation. Glaucomatous GC loss was studied in DBA/2J (D2) mice with wild-type mice as controls. GCs were retrogradely identified and observed with a confocal microscope. The elasticity calculation was also done on published data from patients treated by a gas bubble injection in the vitreous cavity. The GC population in D2 mice (1.5- to 14-mont [...]

Experimental and Statistical Evaluation of the Interaction Effect of Recycled Aggregate and Water/Cement Ratio on Concrete Compressive Strength

Received: 07 March 2021;  Published: 28 July 2021;  doi: 10.21926/rpm.2103032

Abstract

The production of concrete using recycled aggregates, obtained from the processing of construction and demolition waste, is extensively practiced worldwide. However, the effect of simultaneous adding fine recycled aggregate and the recycled coarse aggregate on the mechanical properties of concrete is still unfamiliar. This work aims to evaluate the influence of the water/cement ratio (WC Ratio), the fine recycled aggregate content (%FRA), the coarse recycled aggregate content (%CRA), as well as the interaction betw [...]

Electrochemical Impedance Spectroscopic Studies of PHEV2 form-factor Lithium-ion Cells for Automotive Applications

Received: 09 November 2021;  Published: 18 April 2022;  doi: 10.21926/jept.2202015

Abstract

Prismatic PHEV2 form-factor lithium-ion cells with a nominal capacity of 25 Ah (as used for automotive applications) have been studied with electrochemical impedance spectroscopy (EIS). The data was evaluated using electrical equivalent circuits. Mathematical modeling, system identification, and the determination of model parameters of the lithium-ion cell were also carried out. While a study of the influence of temperature and state-of-charge (SOC) performed using pristine lithium-ion cells showed a nonlinear rela [...]

Electrochemical Synthesis of Germanium-Polypyrrole Composite Nanomaterials in Ionic Liquids for the Fabrication of Lithium-Ion Batteries

Received: 26 December 2021;  Published: 27 March 2022;  doi: 10.21926/jept.2201010

Abstract

Herein, we report the coating of nanostructured germanium using a polypyrrole (PPy) polymer coat as a composite anode material for the fabrication of lithium-ion batteries. The Ge/PPy composites were synthesized following the direct electrochemical deposition method in an ionic liquid (IL). The results revealed that the coating of PPy on Ge helped realize stable battery cycling and reversible capacities, which were not observed in uncoated Ge. The PPy layers could effectively inhibit side reactions between the elec [...]

NaY Zeolite Synthesis from Vermiculite and Modification with Surfactant

Received: 24 October 2023;  Published: 26 December 2023;  doi: 10.21926/cr.2304031

Abstract

This work focuses on preparing NaY zeolite using alternative sources of silica and modifying the zeolite with the surfactant cetyltrimethylammonium bromide. Two different hydrothermal synthesis routes were employed: the conventional method using sodium silicate as the silica source, and the other is a sustainable approach using vermiculite clay as the silica source. In traditional zeolite synthesis, sodium silicate is often used as the source of silica. However, . The vermiculite was subjected to an acid treatment, [...]

Allostatic Mechanism of Mind-Body Medicine for Neuroinflammation

Received: 13 October 2022;  Published: 12 January 2023;  doi: 10.21926/obm.icm.2301005

Abstract

Chronic inflammatory diseases are the most significant cause of death in the world and entail severe impairment to quality of life. The World Health Organization (WHO) ranks chronic inflammatory diseases as the greatest threat to human health and wellbeing. Inflammation is epicentral to many clinical conditions and symptoms, and it is anticipated that the health, economic, and mortality burdens associated with chronic inflammation will steadily increase in the United States over the next 30 years. An inflammatory m [...]

Correlation of CT and MR Perfusion and Permeability Parameters for Intracranial Tumors

Received: 07 October 2018;  Published: 13 January 2019;  doi: 10.21926/obm.neurobiol.1901019

Abstract

Background: Perfusion imaging, mainly MR perfusion (MRP), is performed frequently for brain tumor imaging. CT perfusion (CTP) is less studied as a method for characterizing brain tumors. The purpose of this study was to demonstrate the usefulness of CTP perfusion parameters in evaluating brain tumors and to compare it with MRP measures in the same patient population. Methods: Patients underwent CTP and MRP imaging prospectively. Images were processed with vendor-provided and vendor-neutral software. Four regions of [...]

Defining Clinically Pathogenic HLA-Specific Antibodies - Granular Details in Characteristics in Pre and Early Time Following HLA-Antibody Incompatible Kidney Transplantation

Received: 11 May 2021;  Published: 17 August 2021;  doi: 10.21926/obm.transplant.2103151

Abstract

Antibodies against donor HLA determine access to solid organ transplantation and in many cases the outcome of transplantation, but graft failure is not an inevitable consequence of their presence. Much research has been performed with two main aims – which antibodies represent the highest risk factor prior to transplantation, and second to understand how donor specific HLA antibodies behave after transplantation, with a long-term aim of being able to manipulate their production. HLA antibody incompatible kidney tra [...]

How do Water Companies Address Environmental Indicators in their ESG Reports?

Received: 26 July 2023;  Published: 30 January 2024;  doi: 10.21926/aeer.2401006

Abstract

As climate change is becoming an increasingly crucial issue, it has become critical for firms to report on their Environmental, Social, and Governance (ESG) aspects. In particular, this research analyzes how environmental indicators are dealt with and reported on. In the case study examined, namely the company American Water Works, GHG emissions and water management were the most important issues to the stakeholders according to the materiality assessment. It was found that the firm has significantly reduced its GH [...]

Acute Care Decision-Making for Patients with Advanced Dementia: An Exploratory Study Using Cognitive Task Analysis

Received: 11 November 2020;  Published: 01 March 2021;  doi: 10.21926/obm.geriatr.2101159

Abstract

Decision-making by medical and health care staff forms the core of professional practice. Thought processes, including non-clinical considerations, significantly impact how clinical decisions are made. Such considerations become more relevant when addressing end-of-life care decisions for patients with advanced dementia (PAD). Though palliative care is recommended for this population, its implementation tends to vary. Given the medical staff’s significant influence in guiding clinical decisions, we examined thought [...]
