Tocochromanol, or vitamin E, plays a crucial role in human and animal nutrition and is synthesized only by photosynthetic organisms. γ-Tocopherol methyltransferase (γ-TMT), one of the key enzymes in the tocopherol biosynthetic pathway in plants, converts γ, δ-tocopherols into α-, β-tocopherols. Tocopherol content was investigated in 15 soybean cultivars and GmTMT2 was isolated from five varieties based on tocopherol content. GmTMT2a was expressed in E. coli and the purified protein effectively converted γ-tocopherol into α-tocopherol in vitro. Overexpression of GmTMT2a enhanced α-tocopherol content 4-6-fold in transgenic Arabidopsis, and α-tocopherol content increased 3-4.5-fold in transgenic maize seed, which correlated with the accumulation of GmTMT2a. Transgenic corn that is α-tocopherol-rich may be beneficial for animal health and growth.

Nonalcoholic fatty liver disease (NAFLD) is one of the main causes of chronic liver disorders following liver transplantation. The prorenin receptor (PRR) plays a role in glucose and lipid metabolism, and the hepatic dysregulation of PRR is associated with the upregulation of several molecular pathways, such as the mammalian target of rapamycin (mTOR) and Peroxisome proliferator-activated receptor (PPAR) that promotes hepatic lipogenesis and leads to lipid accumulation in hepatocytes by upregulation of lipogenic genes. PRR inhibition leads to a reduction in the hepatic expression of sortilin-1 and low-density lipoprotein receptor (LDLR) levels and down-regulation of pyruvate dehydrogenase (PDH) and acetyl-CoA carboxylase (ACC) and reduces fatty acids synthesis in hepatocytes.

Objectives: The pathogenesis of premature ovarian insufficiency (POI) not only affects the ovarian structure and function but also gives rise to complications such as osteoporosis and dyslipidemia. Although low-intensity pulsed ultrasound (LIPUS) has been proven effective in treating POI, its impact on the associated complications remains unexplored. Therefore, this study aims to investigate the effects of LIPUS irradiation on osteoporosis and dyslipidemia in a mouse model of POI.

Aim: To identify the barriers and enablers in the implementation of evidence-based physical activity (PA) programmes for the improvement of health outcomes among pregnant women with gestational diabetes mellitus (GDM), and to develop strategies for implementing this evidence in clinical practice.
Methods: A convergent mixed-methods study was conducted, integrating a descriptive qualitative research design with a cross-sectional survey. In-depth interview was used to collect the views and cognitions about physical activity from medical staff, leaders and pregnant women.

Purpose: Assistance from artefacts and humans are traditionally viewed as separate, and it is often up to the individual to try to combine the different kinds of assistance to suit their needs and preferences. The purpose of this study was to gain new insights into the co-existence of and synergies between artefactual and human assistance in the everyday lives of persons with physical and cognitive impairments, through exploring and analysing narratives of individuals who have first-hand knowledge and experience.
Methods: Seven individuals took part in semi-structured interviews, which were then analysed with qualitative content analysis, grounded in cultural-historical activity theory.

Gastrointestinal (GI) symptoms occur frequently in pregnant women, resulting in poor quality of life. These patients frequently require co-management with the obstetrician and a physician/GI specialist. The causation is complex and multifactorial.
