Safe subdural administration and retention of a neurotrophin-3-delivering hydrogel in a rat model of spinal cord injury.

Neurotrophic growth factor (GF) loaded hydrogels have shown promise as a treatment approach for spinal cord injury (SCI). However, SCI presents complex challenges for the direct administration of treatment due to the spinal cord's intricate anatomy and highly sensitive environment. Many current hydrogel administration approaches overlook this complexity, limiting their translational potential.

Perspectives of non-physician partners on barriers and facilitators to AYA cancer care in Latin America.

Background: Cancer is the fourth leading cause of death in adolescents and young adults (AYA) worldwide. Although successful treatment of cancer in AYA has increased in recent years in most of the world, this is not true for many low- and middle-income countries (LMIC) where over 80% of all AYA live. This study investigated the needs of AYA with cancer in parts of Latin America (LATAM) through the perspectives of non-physician health care providers and partners.

A robust method for determining ARs in animal tissues is important for animal postmortem diagnostic and forensic purposes.

How do engineered Yarrowia lipolytica strains secrete free fatty acids: hints from comparative transcriptomics.

Yarrowia lipolytica has been considered one of the most promising platforms for the microbial production of fatty acids and derived products. The deletion of the faa1 gene coding for an acyl-CoA synthetase leads to the accumulation and secretion of free fatty acids (FFAs) into the extracellular space. The secretion of products is beneficial for the development of microbial cell factories to avoid intracellular inhibitory effects and reduce downstream processing costs.

The Knowledge Sharing Capability in Innovative Behavior: A SEM Approach from Graduate Students' Insights.

The capability to share knowledge is considered one of the most relevant components of knowledge management. Moreover, there is little empirical evidence indicating how future human resources in the construction industry value the richness of knowledge sharing and the richness of their innovative behavior. The purposes of this study are (1) to determine which facilitators, from the point of view of master's degree students related to engineering and construction management in Spain, most substantially influence knowledge sharing capability; (2) to test whether knowledge sharing capability (KS) positively influences innovative behavior (IB); and (3) demonstrating whether organizational innovation climate (OIC) is a factor that moderates the relationship between KS and IB.

The oleaginous yeast Starmerella bombicola reveals limitations of Saccharomyces cerevisiae as a model for fatty acid transport studies.

Saccharomyces cerevisiae is the model organism to most yeast researchers, and information obtained from its physiology is generally extrapolated to other yeasts. Studies on fatty acid transport in S. cerevisiae are based on the expression of both native fatty acid export genes as well as heterologous proteins.

Oleaginous yeasts: Time to rethink the definition?

Oleaginous yeasts are typically defined as those able to accumulate more than 20% of their cell dry weight as lipids or triacylglycerides. Research on these yeasts has increased lately fuelled by an interest to use biotechnology to produce lipids and oleochemicals that can substitute those coming from fossil fuels or offer sustainable alternatives to traditional extractions (e.g.

Force in numbers: high-throughput screening approaches to unlock microbial transport.

Biological membranes are inherently complex, making transport processes in microbial cell factories a significant bottleneck. Lack of knowledge on transport proteins' characteristics and the need for advanced technical equipment often hamper transporter identification and optimization. For these reasons, moving away from individual characterization and towards high-throughput mining, engineering, and screening of transporters is an increasingly attractive approach.

Microbial fatty acid transport proteins and their biotechnological potential.

Fatty acid metabolism has been widely studied in various organisms. However, fatty acid transport has received less attention, even though it plays vital physiological roles, such as export of toxic free fatty acids or uptake of exogenous fatty acids. Hence, there are important knowledge gaps in how fatty acids cross biological membranes, and many mechanisms and proteins involved in these processes still need to be determined.

The sad weekend: A perilous North American tradition.

Obesity is a global concern and affects millions of Americans who consume poor-quality diets. Diets directly affect the gut microbiota, which can have subsequent effects on inflammation and contribute to other chronic states. Previously we have shown that a Standard American Diet (SAD) increased immune cell activation and prolonged recovery and that a beneficial diet could reduce these negative effects.
