Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

A socio-legal study on organ shortage in Malaysia

, 2012
Human organs are the most valuable gifts of life. Until today, through organ transplantation, thousands of lives have been saved and many more blessed with hope and happiness through a better quality of living.

Bone marrow mesenchymal stem cells alleviate liver fibrosis after rat liver transplantation through JAK1/STAT5 pathway

Stem Cell Research & Therapy
Objective The effectiveness of bone marrow mesenchymal stem cells (BMSCs) in post-transplantation liver fibrosis has not been studied. The aim of this study was to investigate the effect of BMSCs on liver fibrosis and their role in the Janus-activated ...

Preparation and characterization of small-diameter decellularized scaffolds for vascular tissue engineering in an animal model

BioMedical Engineering OnLine, 2017
Background The development of a suitable extracellular matrix (ECM) scaffold is the first step in vascular tissue engineering (VTE). Synthetic vascular grafts are available as an alternative to autologous vessels in large-diameter arteries (>8 mm) and ...

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Identification of ubiquitination-related signature genes for predicting kidney transplant rejection

Scientific Reports
Kidney transplant rejection (KTR) poses significant challenges to long-term graft survival, with involvement from ubiquitination-related genes (URGs) in immune modulation. This study aimed to identify key URGs linked to KTR and develop a predictive model

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Buddhism, Brain Death and Organ Transplantation [PDF]

, 2010
This article raises concerns about the degree to which potential donors are aware that their layman‖s understanding of death may not be the same as that enshrined in protocols employing the criterion of brain death.

The Mystique of Organ Transplantation [PDF]

Journal of the American College of Surgeons, 2005
The ability to replace faulty body parts with transplanted cells, tissues, and organs has forever altered the principles guiding the practice of medicine. I will first describe how basic science played an essential role in this revolution. But my second objective will be to show how surgeons successfully violated the preexisting rules of immunology and

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.
