Background: Transplantation of isolated islets is one of the most powerful approaches to cure insulin-dependent (type I) diabetes mellitus (IDDM). Currently, the most widely used transplantation strategy is percutaneous perfusion into the liver via the portal vein. However, this approach has several drawbacks and is often limited by the large number of islets required and hypoxic damage to the grafts. Methods: In this article, we posit intrapancreatic parenchymal cell transplantation (IPPCT) as a promisin [...]

A high intra and interindividual pharmacokinetics variability characterize Tacrolimus. Data regarding factors influencing its pharmacokinetics and pharmacodynamics in liver transplantation are limited. This study aimed to assess tacrolimus therapeutic response, pharmacokinetics and adherence in liver transplant recipients. The study was conducted at the Clinical Pharmacology Department for 12 years, from January 2009 to March 2021. We included liver transplant patients treated with tacrolimus referred to our depart [...]

The purpose of this study was to collate and summarize the content covered in published literature describing speech-language pathology management of adult patients with COVID-19 in the acute hospital setting as of February 2022. This review serves as an updated review of the initial recommendations to guide speech-language pathology management for adults with COVID-19 in the acute hospital setting previously provided by Namasivayam-MacDonald and Riquelme in July of 2020. This scoping review followed the Preferred [...]

Denitrifying bioreactor technology, where a solid carbon source (woodchips) acts as a reactive medium to intercept agricultural tile drainage water, has been successfully used to convert N (NO3-) to di-nitrogen (N2) gas. Four replicated field-scale (24 m long × 3 m wide × 1 m deep), bioreactors were built and operated at the St. John's Research and Development Centre and were successful at removing a notable amount of nitrate (N) from agricultural subsurface drainage water. The objective of this study [...]

The concentration of heavy metals in road dust poses significant risks to human health and the environment. This study investigates the characteristics of road dust, focusing on the contamination level of heavy metals like lead (Pb), iron (Fe), and arsenic (As). Road dust samples were collected from various locations in Khulna city. They went through acid digestion to determine the Pb, Fe, and As levels using ICP-OES, and bioavailable iron was assessed by mixing the dust samples with water. This study found no dete [...]

Chromosomal abnormalities represent a significant genetic cause of male infertility because they impair spermatogenesis. The objective of the current study was to determine the prevalence and distribution of chromosomal abnormalities in Greek men with infertility. Four hundred eighty-eight infertile men (27 azoospermic, 168 with oligospermia -98 mild, 57 moderate, 13 severe- and 293 with normospermia) undergoing In Vitro Fertilization (IVF) between 2016-2022 were enrolled in the study. Thirty-eight fertile men were [...]

Background:HLA-G is an immunosuppressive molecule with a potential role in allograft acceptance. Methods:Expression of HLA-G on leucocyte subpopulations was studied in a group of 21 renal transplant patients immediately prior to and 2 months post-transplantation. Results:Significant increases in proportions of total HLA-G+CD4+ T cells were seen (0.5+/-0.1% to 7.9+/-3.2%; p<0.01) and also for CD45RA+, CD45RO+ and CD69+ subsets. Increases in proportions of HLA-G+ cells were also seen in CD8+ T cells and their [...]

Oxidative stress in cerebral ischemia/reperfusion injury (CIRI) involves reactive oxygen and nitrogen species (ROS and RNS). Despite efficient antioxidant pathways in the brain, hypoxia triggers the production of oxygen free radicals and downregulates ATP, which leads to oxidative stress. Sources of free radicals during CIRI include Ca2+-dependent enzymes, phospholipid degradation and mitochondrial enlargement. Upon reperfusion, the abrupt increase of oxygen triggers a massive radical production via enzymes like xa [...]

Background: Normothermic machine perfusion (NMP) utilises 1.2-1.5L of donor blood (DB) with a target perfusate haematocrit of 25% to reanimate the donor heart. Limitations to current practise include small donor size and donor anaemia which can impact on the recovery of these hearts. Furthermore, in donation after circulatory death (DCD), blood collection may delay delivery of preservation solutions resulting in longer warm ischaemic times for the heart and other organs. Banked blood (BB) is a potential alternative [...]

Much evidence has been published which indicates that microvascular endothelial dysfunction, due to cerebrovascular risk factors (e.g., atherosclerosis, hypertension, obesity, diabetes, smoking, aging), precedes cognitive decline in Alzheimer's disease and contributes to its pathogenesis. By incorporating appropriate drug(s) into biomimetic (lipid cubic phase) nanocarriers, one obtains a multitasking combination therapeutic which targets certain cell-surface scavenger receptors, and crosses the blood-brain barrier [...]
