1 lut 2000 · In this review, we will consider first how human fibre diversity is generated and how, nothwithstanding the large heterogeneity observed, human fibres can be grouped and fibre types identified. Then we will consider the molecular diversity and the functional diversity that derive from it.
In this way the histological identification of three main human muscle fibre types (I, IIA and IIX, previously called IIB) has been followed by a precise description of molecular composition and functional and biochemical properties.
19 lip 2024 · This research highlights the organism’s capacity to adapt to molybdenum intake levels, facilitating the elimination of excess at higher intakes and conservation at lower intakes. Such an adaptive response plays a crucial role in mitigating the risks associated with both molybdenum deficiency and toxicity.
2 maj 2011 · For humans, molybdenum functions as a cofactor for at least 4 enzymes: sulfite oxidase, xanthine oxidase, aldehyde oxidase, and mitochondrial amidoxime reducing component. In each case, molybdenum is bound to a complex, multiring organic component called molybdopterin, forming the entity molybdenum cofactor (Figure 1).
1 gru 1998 · In addition to its role in detoxification, molybdenum supports the body's storage of iron and growth.36 Although absorption is inhibited by copper, molybdenum is absorbed well in the gastrointestinal tract by both passive and active transport.
5 maj 2019 · The functional indices developed in this study provide distinct quantitative measures of muscle function in the human lower-limb muscles during dynamic movement tasks, which may be beneficial towards tuning the design and control strategies of physiologically-inspired robotic and assistive devices.
However, there is now evidence that not only changes in muscle mass but other factors underpinning muscle quality including composition, metabolism, aerobic capacity, insulin resistance, fat infiltration, fibrosis and neural activation may also play a role in the decline in muscle function and impaired mobility associated with ageing.
