Evaluating the Performance of a Nonelectronic, Versatile Oxygenating Perfusion System across Viscosities Representative of Clinical Perfusion Solutions Used for Organ Preservation

Bioengineering, 2022
Introduction: On the United States’ Organ Transplantation Waitlist, approximately 17 people die each day waiting for an organ. The situation continues to deteriorate as the discrepancy between harvested organs and the number of patients in need is ...

A Silurian ophiuroid with soft‐tissue preservation [PDF]

Papers in Palaeontology, 2021
AbstractMost Palaeozoic brittle stars lack the fused arm ossicles (vertebrae) that facilitate the remarkable mode of walking that characterizes living forms. Here we describe a stem ophiuroid from the Herefordshire Lagerstätte (Silurian, Wenlock Series), which is exceptional in preserving the body cavity uncompacted and the long tube feet.

Consecutive-Day Ventricular and Atrial Cardiomyocyte Isolations from the Same Heart: Shifting the Cost–Benefit Balance of Cardiac Primary Cell Research

Cells, 2022
Freshly isolated primary cardiomyocytes (CM) are indispensable for cardiac research. Experimental CM research is generally incompatible with life of the donor animal, while human heart samples are usually small and scarce. CM isolation from animal hearts,

Ethanol preservation and pretreatments facilitate quality DNA extractions in recalcitrant plant species

Applications in Plant Sciences, 2023
Premise The preservation of plant tissues in ethanol is conventionally viewed as problematic. Here, we show that leaf preservation in ethanol combined with proteinase digestion can provide high‐quality DNA extracts.

Establishment of a protocol for storage of refrigerated autologous skin [PDF]

Revista Brasileira de Cirurgia Plástica, 2017
INTRODUCTION: Autologous skin grafts are used for treatment of burn patients. These grafts can be stored and preserved, as long as the storage process is performed with strict quality control to reduce the risk of infection.

Inner ear tissue preservation by rapid freezing: improving fixation by high-pressure freezing and hybrid methods [PDF]

, 2014
In the preservation of tissues in as ‘close to life’ state as possible, rapid freeze fixation has many benefits over conventional chemical fixation. One technique by which rapid freeze-fixation can be achieved, high pressure freezing (HPF), has been ...

Effect of Solution and Post-Mortem Time on Mechanical and Histological Properties of Liver during Cold Preservation [PDF]

Biorheology, 2014, Vol. 51, No.1, pp. 47-70, 2021
In this study, we examine the mechanical and histological properties of the bovine liver tissue stored in Lactated Ringers (control), HTK and UW solutions as a function of preservation period. The mechanical experiments are conducted with a shear rheometer on cylindrical tissue samples extracted from 3 bovine livers and the change in viscoelastic ...

Pretreatment with melatonin improves ovarian tissue cryopreservation for transplantation

Reproductive Biology and Endocrinology, 2021
Backgroud Melatonin has anti-inflammatory and antioxidative actions at the mitochondrial level. This indole-containing molecule may protect ovarian grafts during the process of cryopreservation.
