Implantable Biohybrid Artificial Organs

Cell Transplantation, 1995
Biohybrid artificial organs encompass all devices which substitute for an organ or tissue function and incorporate both synthetic materials and living cells. This review concerns implantable immunoisolation devices in which the tissue is protected from immune rejection by enclosure within a semipermeable membrane.

An Object-Oriented Approach to Knowledge Representation in a Biomedical Domain [PDF]

, 1994
An object-oriented approach has been applied to the different stages involved in developing a knowledge base about insulin metabolism. At an early stage the separation of terminological and assertional knowledge was made. The terminological component was

Endoscopic treatment of Kaposi’s sarcoma in a heart transplant patient

Вестник трансплантологии и искусственных органов
Kaposi’s sarcoma (KS) is a malignant tumor caused by human herpesvirus 8. Due to etiological and pathogenetic factors, this type of tumor is common among patients with immunodeficiency of various genesis.

A Brief Comparison Between Available Bio-printing Methods

, 2015
The scarcity of organs for transplant has led to large waiting lists of very sick patients. In drug development, the time required for human trials greatly increases the time to market.

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

A Critical Review of the CRISPR-Cas Technology in the Detection of SARS-CoV-2 Variants

Canadian Journal of Infectious Diseases and Medical Microbiology
Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is still going on, and as the epidemic situation continues, the genome of SARS-CoV-2 is also mutating and evolving, resulting in more and more SARS-

Application of combined endoscopic treatment of patients with bronchial stenosis after lung transplantation using thulium laser, balloon dilation, cryoablation, and airway stenting

Вестник трансплантологии и искусственных органов
Bronchial stenosis (BS) is a persistent, breathing-independent narrowing of the bronchial lumen, primarily brought on by scar and/or granulation tissue.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Aggressive prostate cancer is associated with pericyte dysfunction

Molecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).
