Identification of Autologous Tissue Sources and Optimization of a Treatment Method for Intraoperative Manufacturing of Heart Valve Constructs

open access: yesArtificial Organs, EarlyView.
The use of autologous connective tissue, such as pericardium or peritoneum, combined with controlled tissue treatment, has the potential to result in a more durable heart valve prosthesis than current commercial prostheses. ABSTRACT Introduction Valvular heart disease remains a leading cause of morbidity and mortality. Current biological and mechanical

Lithic analysis in African archaeology: Advances and key themes

open access: yesArchaeometry, EarlyView.
Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

What can lithics tell us about hominin technology's ‘primordial soup’? An origin of stone knapping via the emulation of Mother Nature

open access: yesArchaeometry, EarlyView.
Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)

Does synchronising follicular wave emergence improve outcomes in non‐superstimulated donor cattle undergoing ovum pick‐up (OPU) for in vitro embryo production?

open access: yesAustralian Veterinary Journal, EarlyView.
In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...
