Evaluation of the effectiveness and cost of different hormones in stimulating the spawning of thin lipped grey mullet, Liza ramada [PDF]

The Egyptian Journal of Histology, 2018
Introduction: It is known that mullets are not fully mature in captivity and therefore do not lay eggs. Therefore, hormonalpreparations should be used to stimulate spawning.Aim of the work: To evaluate the effectiveness and cost of using different types ...

Timing feedback-inhibition of the male reproductive hormone axis [PDF]

, 2008
Hormonal methods of male contraception have addressed feedback-inhbition of the cascade of hormones that has evolved to regulate sperm production but high concentrations of testosterone (T) in the blood have not worked satisfactorily.

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Cancer‐associated mutations in endometriosis reframe a benign disease through molecular oncology

Molecular Oncology, EarlyView.
This review aims to comprehensively analyse cancer‐associated somatic mutations (CAMs) present in endometriotic lesions, emphasizing their biological roles, spatial distribution and implications for translational applications in medicine. By contextualizing a benign state within a genomic framework, this analysis seeks to establish its value as a ...

Growth hormone-releasing hormone and extra-pituitary tumorigenesis: therapeutic and diagnostic applications of growth hormone-releasing hormone antagonists

Expert Opinion on Investigational Drugs, 2003
Growth hormone-releasing hormone (GHRH) regulates growth hormone release from the pituitary. However, in addition to this neuroendocrine action, much evidence implies an additional role for GHRH in carcinogenesis in non-pituitary tissues. This role of GHRH in cancer development appears to be due to the operation of several mechanisms, which involve the

Acute Endocrine Alterations After Traumatic Brain Injury and 6‐Month Functional Outcome

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Acute multi‐axis endocrine alterations after traumatic brain injury (TBI) remain incompletely characterized. This study aimed to examine their temporal patterns and explore their associations with 6‐month functional outcome and early inflammatory markers.

Fifty Years of Advances in Neuroendocrinology

Brain and Neuroscience Advances, 2018
Importance of the neuroendocrine brain for health and happiness has become clear since the 1960s. Foundations laid 100 years ago culminated in Geoffrey W Harris’s model of control by the brain of secretion of anterior and posterior pituitary gland ...
