objective(s): ghrelin is a peptide hormone that has been shown to have numerous central and peripheral effects. the central effects including gh secretion, food intake, and energy homeostasis are partly mediated by kiss1- kissr signaling pathway. ghrelin and its receptor are also expressed in the pancreatic islets. ghrelin is one of the key metabolic factors controlling insulin secretion from t...

Amebloblastoma as the most common epithelial odontogenic neoplasm may occur in two forms of central and peripheral. This report presents a case of a 41-year-old Iranian female with a six-month complaint from a painless mass in the right posterior portion of the mandible. The case was diagnosed as an exophytic epulis-like peripheral component with characteristics of peripheral ameloblastoma and ...

In the central and peripheral nervous system Larginine acts as a common substrate for a number of metabolic reactions including the production of polyamines and nitric oxide (NO). NO has become established as a diffusible messenger mediating cell-cell interactions including neuronal signalling [ 11. Recent research has shown that an excess or shortage in NO production has been linked with vario...

Aging produces a decline in the amplitude and precision of 24 h behavioral, endocrine, and metabolic rhythms, which are regulated in mammals by a central circadian pacemaker within the suprachiasmatic nucleus (SCN) and local oscillators in peripheral tissues. Disruption of the circadian system, as experienced during transmeridian travel, can lead to adverse health consequences, particularly in ...

Various extracts of Sarcostemma viminale were screened for central analgesic activity by hot plate test, peripheral analgesic activity by acetic acid-induced writhings, CNS depressant activity by pentobarbitone-induced sleep and locomotor activity testing methods and anthelmintic activity on the earthworms Pheretima posthuma . Results showed that petroleum ether and ethyl acetate extracts h...

osteoma is a benign, slow-growing osteogenic tumor that sometimes arises from the craniomaxillofacial region, such as the sinus, temporal or jaw bones. osteoma consists of compact or cancellous bone that may be peripheral, central or extraskeletal type. peripheral osteoma arises from the periosteum and is commonly a unilateral, pedunculated mushroom-like mass. peripheral osteoma of the mandible...

Persistent pain is a sequela of several neurological conditions with a primary immune basis, such as Guillain-Barré syndrome and multiple sclerosis. Additionally, diverse forms of injury to the peripheral or the central nervous systems--whether traumatic, metabolic, or toxic--result in substantial recruitment and activation of immune cells. This response involves the innate immune system, but e...

Primary pulmonary T-cell lymphoma is an extremely rare malady, and we diagnosed this in a 52-year-old male who was admitted to our hospital with cough for the previous two weeks. The chest CT demonstrated multiple variable sized mass-like consolidations with low density central necrosis in the peripheral portion of both the upper and lower lobes. Positron emission tomography (PET) showed multip...

In recent years, the central nervous system (CNS) has emerged as a principal site of insulin action. This notion is supported by studies in animals relying on intracerebroventricular insulin infusion and by experiments in humans that make use of the intranasal pathway of insulin administration to the brain. Employing neurobehavioural and metabolic measurements as well as functional imaging tech...
