Advancing precision in histocompatibility and immunogenetics: a comprehensive review of the UCLA exchange program.

Precise typing of human leukocyte antigens (HLA) is crucial for clinical hematopoietic stem cell and solid organ transplantations, transfusion medicine, HLA-related disease association, and drug hypersensitivity analysis. The UCLA Cell Exchange program has played a vital role in providing educational and proficiency testing surveys to HLA laboratories worldwide for the past 5 decades. This article highlights the significant contribution of the UCLA Cell and DNA Exchange Programs in advancing HLA antibody testing, genotyping, crossmatches, and, more recently, virtual crossmatches.

Evidence of differential phenotypic plasticity in a desert mustard.

Understanding the effect of the environment on trait variation is critical for ecologically and economically important plants. Here, we asked whether differences in soil moisture are a source of variation in Sahara mustard (). We subjected common garden populations of plants derived from native, invasive, and landrace sources (ranges) to varying water addition treatments.

Cerebrovascular disease lesions are additive and tied to vascular risk factors and cognitive impairment.

Cerebrovascular lesions are prevalent in late life and frequently co-occur but the relationship to cognitive impairment is complicated by the lack of consensus around which lesions represent hallmark pathologies for vascular impairment, particularly in the presence of Alzheimer's disease (AD). We developed an easily applicable model of cerebrovascular disease (CVD), defined as the presence of two or more lesions: moderate to severe cerebral amyloid angiopathy, moderate to severe arteriolosclerosis, infarcts (large, lacunar, or micro), and/or hemorrhages. AD was defined as intermediate or high AD neuropathologic change.

Children's acceptability profiles for biscuits with different fiber content.

Due to the widespread rejection by children of products with high-fiber content, new approaches to meet the dietary recommendations on fiber intake are necessary. To understand which sensory properties influence this rejection, children's acceptability was examined in high-fiber biscuits and drivers of liking were identified. One hundred and ten Spanish children (6-12 years old) evaluated the overall liking of eight commercial biscuits with variable fiber content and stated their preference.

Intake of Fibre-Associated Foods and Texture Preferences in Relation to Weight Status Among 9-12 Years Old Children in 6 European Countries.

Plant foods, rich in fibre, can offer textures that children find difficult to orally manipulate, resulting in low preferences but are important for a healthy diet and prevention of overweight in children. Our aim was to investigate preferences for food texture, intake of fibre-associated foods and the relation to BMI. Three hundred thirty European children (9-12 years, 54% female) indicated their texture preferences using the Child-Food-Texture-Preference- Questionnaire (CFTPQ), and their parents responded on fibre-associated food consumption and anthropometric information.
