Evaluation of anterior pituitary hormone levels in patients with atrial fibrillation

Northwestern Medical Journal
Aim: The risk of ischemic stroke is increased 5-fold in patients with atrial fibrillation (the most common reason for cardiac arrhythmia). The aim is to investigate whether insufficiency in anterior pituitary hormones develops in patients diagnosed with ...

Evidence for adaptive explanations of semelparity in animals

Biological Reviews, EarlyView.
ABSTRACT Semelparity, the reproductive strategy of reproducing once, is widespread but uncommon in animals. Classes of models to explain the evolution of semelparity are based either on age structure and mortality schedules – demographic models in which high post‐reproductive mortality risk favours high reproductive effort and semelparity results from ...

Involvement of the hypothalamic-pituitary-thyroid axis and its interaction with the hypothalamic-pituitary-adrenal axis in the ontogeny of avian thermoregulation: a review [PDF]

, 2008
The emergence of thermoregulation in avian species is a complex matter in which neural as well as hormonal processes are involved. In a previous paper, the neural aspects of primary avian thermoregulation were discussed.

How developmental stressors affect mitochondrial respiratory function: a systematic review and meta‐analysis

Biological Reviews, EarlyView.
ABSTRACT The environmental conditions organisms experience during early development can have powerful and sustained effects on morphology, physiology, behaviour, and performance. Such developmental effects can influence reproductive success, survival, and life‐history strategies and can be transmitted across generations (i.e.

Thyreotropic Hormone of Anterior Pituitary

Experimental Biology and Medicine, 1933
SummaryWe have reported the physiological effects of a highly purified extract of the anterior pituitary containing the thyreotropic hormone, which gives complete replacement therapy in the hypo-physectomized rat and also produces a hyperplasia of the thyroid with hyperthyroidism in both the rat and the guinea pig.

A single cell study of aluminium effect on rat anterior pituitary [PDF]

, 2008
Mestrado em Biologia Molecular e CelularO alumínio foi pela primeira vez reconhecido como um agente neurotóxico para o Homem em 1886. Uma vasta gama de efeitos tóxicos do alumínio a nível celular foi já demonstrada, no entanto permanece desconhecido o ...

CART expression the pituitary hormones.

, 2016
Co-localization of CART with specific pituitary hormones was determined with a CART-specific antibody (green) and hormone specific antibodies (red) in sections from pituitary glands collected at P8.

The influence of circadian variables on ecotoxicology metabolomics

Biological Reviews, EarlyView.
ABSTRACT Ecotoxicologists are using metabolomics increasingly to gain insight into toxicological mechanisms and sublethal effects of chemical exposures. Metabolomics offers a sensitive multi‐parameter approach that can detect biochemical responses not obvious using apical and behavioural endpoints.

Parallel expression patterns of NR4A nuclear receptor family genes in the pituitary gland of proestrus rats

The Journal of Reproduction and Development
The NR4A nuclear receptor family (NR4As), encompassing NR4A1, NR4A2, and NR4A3, exerts pivotal roles in cellular processes through intricate expression patterns and interactions.

A New Hormone of the Anterior Pituitary

Experimental Biology and Medicine, 1932
Riddle and Braucher1 showed that the effective stimulus for the enlargement and functioning (formation of “crop-milk”) of the crop-glands of pigeons is a substance derivable from the anterior hypophysis only; and the luteinizing substance derived from pregnant urine is not that substance. They were unable to decide “whether the principle activating the
