A measurement system has been designed and constructed at NIST for the study of the mechanical properties of synthetic and bovine vascular materials. The measurement technique was validated on latex, where good agreement was found with the Neo-Hookean model. Measurements were also made on expanded polytetrafluoroethylene, which is commonly used for vascular grafts. The measurements of this material were carried out over a pressure range greater than would be seen in vivo. However, the strains were still small enough to effectively apply the Neo-Hookean model to these data.

The rising demand for plant-based meat analogues presents challenges in replicating the sensory qualities of animal meat. This study investigates the impact of Pichia-derived porcine myoglobin (PMb) and bovine hemoglobin (BHb) on the flavor profile, sensory attributes, macrostructure, color, and texture of high-moisture extruded soy protein concentrate-wheat gluten. The addition of PMb and BHb significantly altered the flavor profile by decreasing aldehyde content (hexanal and nonanal), while the contents of ketones (2,3-octanedione and 3,5-octadien-2-one), pyrazines (2-ethyl-6-methylpyrazine), and furans (2-pentylfuran) were increased.

Liver cancer remains a significant global health challenge, characterized by high incidence and mortality rates. Despite advancements in medical treatments, the prognosis for liver cancer patients remains poor, highlighting the urgent need for novel therapeutic approaches. Traditional Chinese medicine (TCM), particularly (CB), has shown promise in addressing this need due to its multi-target therapeutic mechanisms.

Bovine brucellosis (bB) is a zoonosis mainly caused by the species in cattle. Bovine brucellosis can present with either a range of clinical symptoms, including spontaneous abortions in the last trimester of pregnancy, retained fetal membranes, and decreased milk production, or it can be asymptomatic. In Ecuador, vaccination against bB with S19 and/or RB51 is not mandatory and is the responsibility of the farmer.

Hydroxyapatite (HA) is widely used as a bone graft. However, information on the head-to-head osteoinductivity and in vivo performance of micro- and nanosized natural and synthetic HA is still lacking. Here, we fabricated nanosized bovine HA (nanoBHA) by using a wet ball milling method and compared its in vitro and in vivo performance with microsized BHA, nanosized synthetic HA (nanoHA), and microsized synthetic HA (HA).

Orthopedic, maxillofacial, and complex dentoalveolar bone grafting procedures that require donor-site bone harvesting can be associated with post-surgical complications. There has been widespread adoption of exogenously sourced particulate bone graft materials (BGM) for bone regenerative procedures; however, the particulate nature of these materials may lead to compromised healing outcomes, mainly attributed to structural collapse of the BGM, prolonged tissue healing. In this study, a fully synthetic thermoresponsive hydrogel-based universal carrier matrix (TX) that forms flowable and shapable putties with different BGMs while spatially preserving the particles in a 3D scaffold at the implantation site is introduced.
