Nicotinamide (Vitamin B3) Deficiency in Follicular Fluid of Patients With Ovarian Ageing

Journal of Cellular and Molecular Medicine, Volume 30, Issue 6, March 2026.
ABSTRACT Nicotinamide is an essential precursor of NAD involved in energy metabolism. A decline in NAD levels across tissues during ageing is well‐documented, and NAD metabolism has been implicated in ovarian ageing. We investigated the relationship between ovarian ageing and the levels of nicotinamide (NAM) and its metabolite 1‐methylnicotinamide (MNA)

Enviromimetics: From exercise mimetics to cognitomimetics in the quest for enhanced brain health and cognition

The Journal of Physiology, Volume 604, Issue 6, Page 2458-2472, 15 March 2026.
Abstract figure legend A schematic diagram outlining the concept of enviromimetics, and the subclasses of exercise mimetics, epimimetics and cognitomimetics. The rationale is that environmental stimulation and lifestyle factors, including physical activity and cognitive stimulation, have shown beneficial effects across a range of human conditions ...

Early sensorimotor restriction in rats induces age‐dependent mitochondrial alterations in skeletal muscles and brain structures

The Journal of Physiology, Volume 604, Issue 6, Page 2512-2524, 15 March 2026.
Abstract figure legend This study aimed to determine whether early sensorimotor restriction (SMR) alters mitochondrial enzyme activities in rat muscles and brain structures. SMR was induced via immobilizing the hind limbs of pups for 16 h per day during the dark phase from birth to postnatal day (PND) 28.

Role of Septin7 in mitochondrial dynamics and oxidative metabolism in C2C12 skeletal muscle cells

The Journal of Physiology, Volume 604, Issue 5, Page 1971-1994, 1 March 2026.
Abstract figure legend Knockdown of Septin7 alters the expression of markers responsible for mitochondrial dynamics. Members of the electron transport chain are also affected by diminished Septin7 level resulting in functional changes of mitochondrial respiration. Abstract Mitochondria are dynamic organelles that undergo fusion and fission.
