The impact of frailty syndrome on skeletal muscle histology: preventive effects of exercise
FEBS Open Bio, EarlyView.Frailty syndrome exacerbates skeletal muscle degeneration via increased ECM deposition and myofiber loss. This study, using a murine model, demonstrates that endurance exercise attenuates these histopathological alterations, preserving muscle integrity. Findings support exercise as a viable strategy to counteract frailty‐induced musculoskeletal decline

Economic Botany, 1949 Large-scale use of plant growth-regulating chemicals, unheard of ten years ago, has fostered a multimillion dollar business. In 1948, 27 1/2 million pounds of 2,4-D, once used only in minute doses for laboratory work, were manufactured for agricultural use, primarily in weed eradication.

Plant hormones, plant growth regulators
Orvosi Hetilap, 2014Plants seem to be rather defenceless, they are unable to do motion, have no nervous system or immune system unlike animals. Besides this, plants do have hormones, though these substances are produced not in glands. In view of their complexity they lagged behind animals, however, plant organisms show large scale integration in their structure and ...

Journal of Range Management, 1962
There is disclosed a class of alpha , alpha -disubstituted-5-pyrimidinemethanes and substituted methanes which are useful as plant growth regulators. Internodal elongation of plants is inhibited by treatment with a compound of this invention.

Castanospermine?a plant growth regulator
Journal of Chemical Ecology, 1988Castanospermine, 1,6,7,8-tetrahydroxyoctahydroindolizine, has been shown to be a potent dicot phytotoxin. The effective concentration to inhibit root length elongation of dicot roots by 50% is 300 ppb, while the effective concentration against monocot roots is 200 ppm, i.e., 10(3) times less effective.

Plant Growth Regulators, Viruses and Plant Growth
1990Virus infection alters plant growth and development. The role of plant growth regulators (PGRs) in control of these processes in diseased plants is reviewed, taking tobacco mosaic virus infections of tobacco and tomato as the main model systems. Growth inhibition was related primarily to severity of visible mosaic symptoms rather than to the extent of ...

Quinones as plant growth regulators [PDF]
Plant Growth Regulation, 1985 The effects of benzoquinone, naphthaquinone and anthraquinone on the growth of tomato callus, whole plants of tomato and on rooting of mungbean cuttings were studied. Naphthaquinone effects on some oxidases and on the isozyme patterns of peroxidases in all the three systems were also observed.
