In former investigations we have studied the growth processes which take place in the mammary gland ( 1 j and in the vagina and cervix ( 2 ) of mice under the 'influence of estrogenic hormones, and the conditions under which these .processes become cancerous. The investigations recorded here extend this analysis to the uterus of the mouse. By uterus, we understand that part of the vaginal-cervi...

Initial suggestions that suppression of growth may be an intrinsic characteristic of attention-deficit/hyperactivity disorder (ADHD) have now largely been disproven. Although controversy persists regarding the possible negative effect of adrenergic stimulants on growth in children with ADHD, the consensus that appears to be reached in the scientific literature is that stimulant usage may cause ...

BYERS J. A., BREWER J. W. & DENNA D. W. 1976. Plant growth hormones in pinyon insect galls. Marcellio 39, 125-134. Larvae of the midge Janetiella sp. near J. coloradensis Felt (Diptera: Cecidomyiidae) cause galls at the base of young needles of pinyon Pinus edulis Engelm. Bioassays of extracts from these galls contained as much as 17 times more auxin activity and as much as 21 times more gibber...

Apoptosis or programmed cell death is a physiological form of cell death that occurs in embryonic development and during involution of organs. It is characterized by distinct biochemical and morphological changes such as DNA fragmentation, plasma membrane blebbing and cell volume shrinkage. Many hormones, cytokines and growth factors are known to act as general and/or tissue-specific survival f...

We recently isolated a mammary growth factor from mouse mammary fibroblast-conditioned medium and identified it as a homologue of human HGF (hepatocyte growth factor) (Sasaki et al. Biochem Biophys Res Commun 199: 772-779,1994). To elucidate the role of mammary fibroblast-derived HGF in mammary epithelial cell growth in vivo, we used recombinant mouse HGF and examined its effect on the growth o...

Skeletal muscle is affected by many hormones and growth factors, both catabolic and anabolic in nature. Our understanding of the synthesis, release, transport and tissue sensitivities of these hormones has increased greatly in recent years. Despite this knowledge we still do not know the link between hormonal/growth factor release, training and muscle hypertrophy. The hormonal response to high ...

Between 1995 and 2018, the production of fish fishery products using feed increased from 12 to 54.3 million tons. In cultivation such in many countries, hormones are widely used as growth stimulants increase efficiency conversion for purpose sex reversal, well artificial reproduction. Hormones, especially their synthetic forms, poorly metabolized marine organisms, which leads accumulation food ...

A total of 260 tail blastemata (13 to 15-day regenerates) of adult newts was cultured, with 170 controls, in medium no. 1760 (modified Parker's Medium, CMRL-1415) for 98 h at 20 ±0-5 °C. Various hormones, related to the regeneration process, were added individually and in combinations. If hormones were not included in the culture medium, blastema growth and differentiation did not ensue. The re...
