Physiological Basis of Sprouting Potential in Bermudagrass
Agronomy Journal, 2017Core Ideas Large genotypic variation for sprouting of stolons was identified. Sprouting percentage was strongly associated with stolen diameter. Sprouting was related photoassimilate supply on an amount per node basis. The size and/or maturity of the axillary buds were also possible factors.

Medical Teacher, 2013
Misconceptions are mental models of phenomena that are at variance with accepted scientific models of these phenomena.The goal of this study was to investigate the prevalence of some misconceptions among students about cardiovascular physiology and to evaluate the effectiveness of cardiovascular physiology teaching in alleviating these misconceptions.A

Physiologic basis of potentials recorded in electromyography
Muscle & Nerve, 2000The extracellularly recorded configuration of a single muscle fiber discharge is generally appreciated to be triphasic with an initially positive deflection. However, careful attention to waveform appearance during the electrodiagnostic medicine examination reveals that both innervated and denervated muscle waveforms may display a pantheon of ...

The contraceptive potential of fertilization: a physiological perspective
Human Reproduction, 1994Several separate events of the fertilization sequence (sperm capacitation, regulated sperm transport in the oviduct, sperm-cumulus interaction, sperm-zona binding, the acrosome reaction, zona penetration, gamete fusion) represent points at which conception might be preventable. Each is considered variously with reference to its biological significance,

Melanopsin: photoreceptors, physiology and potential
Current Opinion in Physiology, 2018The discovery of melanopsin-expressing photosensitive retinal ganglion cells (pRGCs) has led to a fundamental change in our understanding of retinal light detection. pRGCs perform a broad range of non-visual functions — most notably mediating circadian entrainment to the environmental light/dark cycle.

The potential relevance of cytokines to ovarian physiology
The Journal of Steroid Biochemistry and Molecular Biology, 1992Elucidating the secrets of intraovarian intercellular communication constitutes a central area of investigation. While most attention has been directed thus far at the somatic cellular components of the ovary, the potential role(s) and relative importance of the resident ovarian white blood cell have received relatively limited attention.

On the potential role of proopiomelanocortin in skin physiology and pathology
Molecular and Cellular Endocrinology, 1993Pro-opiomelanocortin (POMC) is the precursor of ACTH, alpha-MSH and beta-endorphin, neuropeptides with multiple regulatory functions. Both the pituitary gland and peripheral tissues such as mammalian skin are capable of generating POMC-derived neuropeptides.

Physiological, pathological and potential therapeutic roles of adipokines
Drug Discovery Today, 2012Formerly regarded purely as passive energy storage, adipose tissue is now recognized as a vital endocrine organ. Adipocytes secrete diverse peptide hormones named adipokines, which act in a autocrine, paracrine or endocrine way to influence several biological functions.

Physiological mechanisms underlying long-term potentiation
Trends in Neurosciences, 1988Abstract In 1949, D. O. Hebb suggested a synaptic modification for learning and memory that occurs as a consequence of coincidence between pre- and post-synaptic activity 1 . This concept has gained wide acceptance and is often used, in its original or modified form, in neuronal net models dealing with learning and memory 2 .

Research Potentials in Voice Physiology.
Archives of Otolaryngology - Head and Neck Surgery, 1965This book is a compendium arising from a conference of international scientists held at the State University of New York, Upstate Medical Center, in May 1961 to review phonatory physiology; to discuss neuromuscular mechanisms of hearing and speech; to explore the use of new research tools; and to identify unsolved problems in phonation.
