Modeling and analysis of a prosthetic foot: A numerical simulation case study.

Background: The prosthetic foot is an essential component of the prosthetic limb used by people who suffer from amputation. The prosthetic foot or limb is expensive in developing countries and cannot be used by most people with special needs.

Objective: In this study, an uncomplicated prosthetic foot is designed that can be manufactured at low costs using 3D printer technology and can be provided to a wide range of amputees.

Poor sleep quality in children with atopic dermatitis and its effects on behavior: A multicenter cross-sectional study from a low-middle-income country.

Background: Sleep disturbance in children with atopic dermatitis (AD) frequently goes unnoticed and can be associated with behavioral challenges. The aims of this study were to determine (a) the prevalence and factors associated with sleep disturbance and behavioral problems and (b) the correlation between sleep disturbance and behavioral problems in children with AD.

Methods: This cross-sectional study involved children aged 4-12 years old with moderate to severe AD.

Fut9 Deficiency Causes Abnormal Neural Development in the Mouse Cerebral Cortex and Retina.

α1,3-Fucosyltransferase 9 (Fut9) is responsible for the synthesis of Lewis X [Le, Galβ1-4(Fucα1-3)GlcNAc] carbohydrate epitope, a marker for pluripotent or multipotent tissue-specific stem cells. Although Fut9-deficient mice show anxiety-related behaviors, structural and cellular abnormalities in the brain remain to be investigated. In this study, using in situ hybridization and immunohistochemical techniques in combination, we clarified the spatiotemporal expression of Fut9, together with Le, in the brain and retina.

Antioxidant Modulation of mTOR and Sirtuin Pathways in Age-Related Neurodegenerative Diseases.

In the human body, cell division and metabolism are expected to transpire uneventfully for approximately 25 years. Then, secondary metabolism and cell damage products accumulate, and ageing phenotypes are acquired, causing the progression of disease. Among these age-related diseases, neurodegenerative diseases have attracted considerable attention because of their irreversibility, the absence of effective treatment and their relationship with social and economic pressures.

Cellular Uptake and Bioavailability of Tocotrienol-Rich Fraction in SIRT1-Inhibited Human Diploid Fibroblasts.

Tocotrienol-rich fraction (TRF) is palm vitamin E that consists of tocopherol and tocotrienol. TRF is involved in important cellular regulation including delaying cellular senescence. A key regulator of cellular senescence, Sirtuin 1 (SIRT1) is involved in lipid metabolism.
