Enzymatic hydrolysis approach is commonly employed for preparation of active peptides, while the limited purity and yield of produced peptides hinder further development of action mechanisms. This study presents the biotechnological approach for the efficient production of recombinant angiotensin converting enzyme (ACE) inhibitory peptide LYPVK and investigates its potential antihypertensive action mechanism. DNA encoding sequence of recombinant peptide was designed to form in tandem, which was expressed in Escherichia coli BL21 (DE3).

Background/objectives: While studies in rat pups suggest that early zinc exposure is critical for optimal brain structure and function, associations of prenatal zinc intake with measures of brain development in infants are unknown. This study aimed to assess the associations of maternal zinc intake during pregnancy with MRI measures of brain tissue microstructure and neurodevelopmental outcomes, as well as to determine whether MRI measures of the brain mediated the relationship between maternal zinc intake and neurodevelopmental indices.

Methods: Forty-one adolescent mothers were recruited for a longitudinal study during pregnancy.

The strong motion records collected in full-scale structures provide the ultimate evidence of how real structures, in situ, respond to earthquakes. This paper presents a novel method for visualization, in three dimensions (3D), of the collective motion by a dense array of sensors in a building. The method is based on one- and two-dimensional biharmonic spline interpolation of the motion recorded by multiple sensors on the same or multiple floors.

FAM98 Family Proteins Play Distinct Roles in Osteoclastogenesis and Bone Resorption.

Biology (Basel)

January 2025

Southern California Institute for Research and Education, VA Long Beach Medical Center, Long Beach, CA 90822, USA.

There are three FAM98 family proteins (FAM98A/B/C) in humans and mice. Their physiological functions remain largely unknown. We have previously reported that Fam98a interacts with Plekhm1 in murine osteoclasts and functions in lysosome trafficking/secretion and bone resorption in osteoclasts in vitro.

Mutations in cancer risk genes increase susceptibility, but not all carriers develop cancer. Indeed, while DNA mutations are necessary drivers of cancer, only a small subset of mutated cells go on to cause the disease. To date, the mechanisms underlying individual cancer susceptibility remain unclear.

Pre-injury narcotic drug use in isolated severe traumatic brain injury: effect on outcomes.

Eur J Trauma Emerg Surg

January 2025

Division of Acute Care Surgery, Department of Surgery, University of Southern California, 2051 Marengo Street, Los Angeles, CA, 90033, USA.

Purpose: The aim of this study was to explore the association between pre-injury narcotic drug use (opioids, methadone, and/or oxycodone) and outcomes in isolated severe traumatic brain injury (TBI) patients.

Methods: ACS TQIP study included adult trauma patients (≥ 16 years) with complete drug and alcohol screening. Isolated severe TBI was defined as head trauma with AIS 3-5 and without significant extracranial trauma.

While highly morbid forms of chronic graft versus host disease (cGVHD) and severe late effects of allogeneic hematopoietic cell transplant (HCT) can impact children and adults alike, unique considerations arise in pediatric cases regarding diagnosis, monitoring, treatment, and likelihood of resolution. As children can present with atypical features of cGVHD, and with more significant disease due to inability to communicate symptoms, they may be at increased risk for highly morbid forms of cGVHD and incur greater subsequent late effects, which may be more pronounced in those with underlying chromosomal breakage syndromes, with higher prevalence in pediatric HCT recipients. The long-term effects of cGVHD and its therapies include impaired immune reconstitution, leading to increased risks of infection and secondary malignant neoplasms.

Cetaceans exhibit remarkable wound healing capabilities. However, the specific immune mechanisms underlying this process, particularly the role of γδ T cells, remains largely unexplored. In ruminants, pigs, and camelids, which are members of the order Cetartiodactyla alongside cetaceans, γδ T cells express a unique receptor called workshop cluster 1 (WC1).

Background: Approximately 5 % of children and adolescents in foster care are placed in group home settings, with adolescents making up the largest age group in these placements. Group home placement is designed to support individuals with high acuity or specialized needs that cannot be met in a family-based setting. Prior research has highlighted the vulnerabilities of adolescents in group homes, including behavioral issues, mental health concerns, and juvenile justice system involvement.

Objective: The present study aimed to investigate the association between pituitary adenoma (PA) consistency and other measurable tumor characteristics, extent of resection (EOR), postoperative complications, and outcomes.

Methods: In total, 507 PA resections were intraoperatively assigned a consistency grade from 1 (cystic/hemorrhagic tumors) to 5 (calcified tumors) based on intraoperative tumor characteristics. Tumor consistency was analyzed in tertiles (grades 1 and 2, grade 3, and grades 4 and 5) to determine associations with tumor characteristics, EOR, recurrence, postoperative outcomes, and complications.

The functional properties of tetraaryl compounds, M(aryl) (M = transition metal or group 14 element), are dictated not only by their common tetrahedral geometry but also by their central atom. The identity of this atom may serve to modulate the reactivity, electrochemical, magnetic, and optical behavior of the molecular species, or of extended materials built from appropriate tetraaryl building blocks, but this has not yet been systematically evaluated. Toward this goal, here we probe the influence of Os(IV), C, and Si central atoms on the spectroelectrochemical properties of a series of redox-active tetra(ferrocenylaryl) complexes.

Background: Cardiovascular disease (CVD) morbidity and mortality is increasing in Africa, largely due to undiagnosed and untreated hypertension. Approaches that leverage existing primary health systems could improve hypertension treatment and reduce CVD, but cost-effectiveness is unknown. We evaluated the cost-effectiveness of population-level hypertension screening and implementation of chronic care clinics across eastern, southern, central, and western Africa.
