Multiplexed Nanosensors for Real‐Time Monitoring of VOC‐Mediated Signalling Response in Plants

Plant, Cell &Environment, EarlyView.
ABSTRACT To enhance crop performance, intercropping strategies leverage volatile organic compound (VOC)‐driven interactions with companion plants that constitutively emit VOCs. Despite the agricultural importance, the mechanisms and kinetics of VOC‐mediated sensory transduction in receiver plants eavesdropping on neighbouring non‐kin emitters remain ...

Comparative effects of b-carotene and fucoxanthin on retinol deficiency induced oxidative stress in rats

, 2009
This study aimed at comparing antioxidant potential of fucoxanthin (FUCO) with b-carotene in relieving lipid peroxidation (Lpx) caused by retinol deficiency (RD) in rats. RD rats (n = 45) were fed a dose of either b-carotene (0.81 lmol) or FUCO (0.83

Divergent structure–function coordination shapes leaf thermal tolerance in Mediterranean tree species

Plant Biology, EarlyView.
Tcrit (critical temperature) may reflect early, adaptive photoprotective downregulation of PSII in Quercus ilex, whereas in Acer campestre and Fraxinus ornus, it may more closely correspond to the onset of thermal PSII vulnerability. Abstract Increasing temperatures impair photosynthetic apparatus by damaging photosystem II (PSII) efficiency.

The Effect of b-carotene on desaturation of ruminant fat

, 2000
An experiment was conducted to determine if limiting the amount of β-carotene in a diet could increase the expression of the gene responsible for the desaturation of saturated fats in a ruminant.

From senescence and inflammaging to systemic comorbidities: Drivers of aging‐associated periodontitis

Periodontology 2000, EarlyView.
Abstract Background Aging is accompanied by a chronic low‐grade inflammatory process, known as inflammaging, as well as immunosenescence, an age‐related decline and dysregulation of immune function, and cellular senescence, a process in which cells enter a state of irreversible growth arrest while actively releasing pro‐inflammatory factors.

Ovarian hormone loss modifies the nucleic acid cargo of circulating extracellular vesicles and skeletal muscle metabolism after acute exercise in rats

Experimental Physiology, EarlyView.
Abstract Loss of ovarian hormones (i.e., menopause) leads to negative effects on metabolic health. While exercise offers significant benefits, it seems to be insufficient to completely reverse these changes. The mechanisms by which exercise conveys the effects throughout the body are still poorly understood.
