  • The Potential Therapeutic Effect of Melatonin in Gastro-Esophageal Reflux Disease Tharwat S Kandil1*, Amany a Mousa2, Ahmed a El-Gendy3, Amr M Abbas3
    Kandil et al. BMC Gastroenterology 2010, 10:7 http://www.biomedcentral.com/1471-230X/10/7 RESEARCH ARTICLE Open Access The potential therapeutic effect of melatonin in gastro-esophageal reflux disease Tharwat S Kandil1*, Amany A Mousa2, Ahmed A El-Gendy3, Amr M Abbas3 Abstract Background: Gastro-Esophageal Reflux Disease (GERD) defined as a condition that develops when the reflux of stomach contents causes troublesome symptoms and/or complications. Many drugs are used for the treatment of GERD such as omeprazole (a proton pump inhibitor) which is a widely used antiulcer drug demonstrated to protect against esophageal mucosal injury. Melatonin has been found to protect the gastrointestinal mucosa from oxidative damage caused by reactive oxygen species in different experimental ulcer models. The aim of this study is to evaluate the role of exogenous melatonin in the treatment of reflux disease in humans either alone or in combination with omeprazole therapy. Methods: 36 persons were divided into 4 groups (control subjects, patients with reflux disease treated with melatonin alone, omeprazole alone and a combination of melatonin and omeprazole for 4 and 8 weeks) Each group consisted of 9 persons. Persons were subjected to thorough history taking, clinical examination, and investigations including laboratory, endoscopic, record of esophageal motility, pH-metry, basal acid output and serum gastrin. Results: Melatonin has a role in the improvement of Gastro-esophageal reflux disease when used alone or in combination with omeprazole. Meanwhile, omeprazole alone is better used in the treatment of GERD than melatonin alone. Conclusion: The present study showed that oral melatonin is a promising therapeutic agent for the treatment of GERD.

    07. Endocrine, Reproductive and Urogenital Pharmacology 07.001 Mirabegron relaxes urethral smooth muscle by a dual mechanism involving β3-Adrenoceptor activation and α1-adrenoceptor blockade. Alexandre EC1, Kiguti LR2, Calmasini FB1, Ferreira R3, Silva FH1, Silva KP2, Ribeiro CA2, Mónica FZ1, Pupo AS2, Antunes E1 1FCM-Unicamp – Farmacologia, 2IBB-Unesp, 3FCM- Unicamp – Hematologia e Hemoterapia Introduction: Overactive bladder syndrome (OAB) is a subset of storage LUTS (lower urinary tract symptoms) highly prevalent in diabetes, obesity and hypertension. Benign prostatic hyperplasia (BPH) in aging men is another pathological condition highly associated with OAB secondary to bladder outlet obstruction (BOO). The β3- adrenoceptor apparently is the major receptor to induce bladder relaxations. Mirabegron is the first β3-adrenoceptor (β3-AR) agonist approved for OAB treatment (Chapple et al., 2014). Urethral smooth muscle plays a critical role to urinary continence, but no studies have examined the mirabegron-induced urethral relaxations. Aims: This study was designed to investigate the mirabegron-induced mouse urethral relaxations. In preliminary assays, mirabegron showed an unexpected action by competitively antagonizing the urethral contractions induced by the α1-AR agonist phenylephrine. Therefore, this study also aimed to characterize the α1-AR blockade by mirabegron, focusing on the α1-AR subtypes in rat vas deferens and prostate (α1A- AR), spleen (α1B-AR) and aorta (α1D-AR) preparations. Methods: Functional assays were carried out in mouse urethra rings, and rat vas deferens, prostate, aorta and spleen. β3-AR expression (mRNA and immunohistochemistry) and cyclic AMP levels were determined in mouse urethra. Competition assays for the specific binding of [3H]Prazosin to membrane preparations of HEK 293 cells expressing each of the human α1-ARs subtypes were performed.

Rolling My Third Eye: The Third Eye and Pineal Gland Connection By Shannon Bow Jackson D.U.Quark 2020. Volume 5 (Issue 1) pgs. 6-13 Published December 27, 2020 Staff Article Chances are the optometrist only checks that two of your eyes are functioning. But what about your third eye; who checks on that? A neurologist? Spiritual Healer? Yoga Instructor? Yourself? The answer might vary, given that this third eye is believed to reside within the pineal gland inside of the brain. The name “third eye” comes from the pineal gland’s primary function of ‘letting in light and darkness’, just as our two eyes do. This gland is the melatonin-secreting neuroendocrine organ containing light-sensitive cells that control the circadian rhythm (1). The diagram shows that nerve cells in the retinas of our eyes allow for light to be sensed. When there is light, the nerve cells in the retina then signal to the suprachiasmatic nucleus (SCN) in the hypothalamus.

  • The Digestive System
    69 chapter four THE DIGESTIVE SYSTEM THE DIGESTIVE SYSTEM The digestive system is structurally divided into two main parts: a long, winding tube that carries food through its length, and a series of supportive organs outside of the tube. The long tube is called the gastrointestinal (GI) tract. The GI tract extends from the mouth to the anus, and consists of the mouth, or oral cavity, the pharynx, the esophagus, the stomach, the small intestine, and the large intes- tine. It is here that the functions of mechanical digestion, chemical digestion, absorption of nutrients and water, and release of solid waste material take place. The supportive organs that lie outside the GI tract are known as accessory organs, and include the teeth, salivary glands, liver, gallbladder, and pancreas. Because most organs of the digestive system lie within body cavities, you will perform a dissection procedure that exposes the cavities before you begin identifying individual organs. You will also observe the cavities and their associated membranes before proceeding with your study of the digestive system. EXPOSING THE BODY CAVITIES should feel like the wall of a stretched balloon. With your skinned cat on its dorsal side, examine the cutting lines shown in Figure 4.1 and plan 2.

Received: 13 January 2018; Accepted: 26 January 2018; Published: 31 January 2018 Abstract: The pineal gland is a unique organ that synthesizes melatonin as the signaling molecule of natural photoperiodic environment and as a potent neuronal protective antioxidant. An intact and functional pineal gland is necessary for preserving optimal human health. Unfortunately, this gland has the highest calcification rate among all organs and tissues of the human body. Pineal calcification jeopardizes melatonin’s synthetic capacity and is associated with a variety of neuronal diseases. In the current review, we summarized the potential mechanisms of how this process may occur under pathological conditions or during aging. We hypothesized that pineal calcification is an active process and resembles in some respects of bone formation. The mesenchymal stem cells and melatonin participate in this process. Finally, we suggest that preservation of pineal health can be achieved by retarding its premature calcification or even rejuvenating the calcified gland. Keywords: pineal gland; calcification; melatonin; aging; neurodegenerative diseases; rejuvenation 1. Introduction Pineal gland is a unique organ which is localized in the geometric center of the human brain. Its size is individually variable and the average weight of pineal gland in human is around 150 mg [1], the size of a soybean.

    THE MACIHNE BRAIN AND PROPERI1ES OF THE l\1IND Robert O. Becker, M.D. ABSTRACf It is the author's contention that modem neurophysiology is based upon the operations ofless than half of the brain and that the anatomical and functional existence of more than half of the cells constituting the nelVOW system are ignored. The author argues that the neurone doctrine, which holds that all functions of the nervow system are the result of operations of the neurons alone, is incomplete, and that a more basic and primitive information transfer system resides in these neglected cdls. Theoretical considerations. prior dc:ctrophysiological evidences which were ignored, modem aspects of electrophysiology and evidence derived from the new science of bioelearomagnetics will be presented to support the theory of a "dual nervow system."

  • Pineal Gland - a Mystic Gland Daniel Silas Samuel1, Revathi Duraisamy1, M
    Review Article Pineal gland - A mystic gland Daniel Silas Samuel1, Revathi Duraisamy1, M. P. Santhosh Kumar2* ABSTRACT The pineal gland has been the subject of amazement and awe down the centuries. The structure and function of this enigmatic gland play an important role in day-to-day life of human beings. The pineal gland secretes an important hormone melatonin which is necessary for lightening the skin tone, and it has several other important functions in humans. The pineal gland is composed mainly of pinealocytes. The pineal gland is present in the midline of the skull and is a part of epithalamus and hypothalamus. It regulates the secretion of both. The pineal gland is activated by darkness and it is mandatory to maintain a normal circadian rhythm of sleep-wake cycle, if not humans may turn into zombies. The pineal gland is also present in animals. The secretion of this gland in higher amounts causes precocious puberty and development of primary and secondary sexual characters mainly in boys. It is also called the third eye since after eye, and it is the only gland which detects light but, on the contrary, secretes melatonin largely under darkness. This gland also affects the mood of human beings, thereby getting involved in the psychological behavior of men. It increases the immune action of human beings; thereby, it also acts as immunostimulant preventing a person from attack of antigen by producing a suitable antibody. Its presence hinders the spread of tumor and becomes malignant, and its calcification affects the memory or the memorizing capacity of the brain leading to dementia.

Additionally, it investigated changes in the content of norepinephrine, dopamine, and their metabolites [3,4-dihydroxyphenylacetic acid; vanillylmandelic acid (VMA); homovanillic acid] in goose pineal glands in vivo under 12 h of light and 12 h of darkness (LD), a reversed cycle (DL), constant light (LL), and constant darkness (DD). In vitro content of melatonin was measured by radioimmunoassay; contents of catecholamines and their metabolites were measured by high-performance liquid chromatography. Exposure of pineal explants to LD or DL established rhythmic melatonin secretion; this rhythm was much better entrained with norepinephrine exposure during photophase than without it.
