The Deceased, Public Health, and Research: Proposing Legal Reforms
Biopreserv Biobank. 2023 Nov 9. doi: 10.1089/bio.2023.0026. Online ahead of print.ABSTRACTThere is little guidance concerning biomedical research using tissues from deceased individuals. Unique ethical and legal challenges gained visibility during the coronavirus disease 2019 (COVID-19) pandemic, when important studies using genome sequencing required access to biological materials from deceased individuals. These studies proposed to determine whether specific genomic profiles were associated with important disease outcomes. Such research has previously required consent from next-of-kin or other surrogate decision makers. ...

Improved Biorepository to Support Sickle Cell Disease Genomics and Clinical Research: A Practical Approach to Link Patient Data and Biospecimens from Muhimbili Sickle Cell Program, Tanzania
This article documents the physical verification process of biospecimens in the biorepository, connecting them to patient clinical and demographic data and aiding in the planning of future genomic and clinical research studies' experience from the Muhimbili Sickle Cell Program in Dar es Salaam, Tanzania. The biospecimen database was updated with the current biospecimen position following the physical verification and then mapping this information to its demographic and clinical data using demographic identifiers. The biorepository stored 74,079 biospecimens in three -80°C freezers, including 63,345 from 5159 patients enro...

Increase in Serum Potassium Levels After Refrigerated Storage: A Component of Blood Clot Contaminates the Serum Layer Over the Separator Gel
Conclusions: Potassium levels increase when serum is refrigerated in collection tubes containing separating gel. This can be attributed to contamination of the serum layer by blood cell components beyond the separating gel.PMID:37943629 | DOI:10.1089/bio.2022.0217 (Source: Biopreservation and Biobanking)

A Method to Freeze Skin Samples for Cryobanks: A Test of Some Cryoprotectants for an Endangered Deer
This study's objective was to test cryopreservation protocols of skin fragments of M. jucunda, using different cryoprotectants in slow freezing. We evaluated four treatments, composed of three cryoprotectants, dimethyl sulfoxide (DMSO), polyvinylpyrrolidone (PVP), and ethylene glycol (EG), used alone and in combination. There was also a control group where the tissue did not undergo cryopreservation. Skin fragments were collected from the medial region of the pelvic limbs of three individuals. Each fragment was divided into 10 equal parts, standardized by weight, making two pieces for each treatment and control from each a...
