  • ENERGY RICH COMPOUNDS ,ATP and CYCLIC AMP UNIT– I: Bioenergetics
    BIOENERGETICS ENERGY RICH COMPOUNDS ,ATP AND CYCLIC AMP UNIT– I: Bioenergetics Defination - Bioenergetics means study of the transformation of energy in living organisms. - The goal of bioenergetics is to describe how living organisms acquire and transform energy in order to perform biological work. The study of metabolic pathways is thus essential to bioenergetics. - In a living organism, chemical bonds are broken and made as part of the exchange and transformation of energy. Energy is available for work (such as mechanical work) or for other processes (such as chemical synthesis and anabolic processes in growth), when weak bonds are broken and stronger bonds are made. The production of stronger bonds allows release of usable energy. - Adenosine triphosphate (ATP) is the main "energy currency" for organisms; the goal of metabolic and catabolic processes are to synthesize ATP from available starting materials (from the environment), and to break- down ATP (into adenosine diphosphate (ADP) and inorganic phosphate) by utilizing it in biological processes. - In a cell, the ratio of ATP to ADP concentrations is known as the "energy charge" of the cell. - A cell can use this energy charge to relay information about cellular needs; if there is more ATP than ADP available, the cell can use ATP to do work, but if there is more ADP than ATP available, the cell must synthesize ATP via oxidative phosphorylation. - Living organisms produce ATP from energy sources via oxidative phosphorylation. The terminal phosphate bonds of ATP are relatively weak compared with the stronger bonds formed when ATP is hydrolyzed (broken down by water) to adenosine diphosphate and inorganic phosphate.

  • Adverse Effects of Mouth Breathing
    AGD - Academy of General Denstry hp://www.agd.org/publicaons/arcles/?ArtID=6850 Mouth breathing: Adverse effects on facial growth, health, Contact Us academics, and behavior Send to a Friend By Yosh Jefferson, DMD, MAGD Send to Printer Featured in General Dentistry , January/February 2010 Pg. 18-25 Close Window Posted on Friday, January 08, 2010 The vast majority of health care professionals are unaware of the negative impact of upper airway obstruction (mouth breathing) on normal facial growth and physiologic health. Children whose mouth breathing is untreated may develop long, narrow faces, narrow mouths, high palatal vaults, dental malocclusion, gummy smiles, and many other unattractive facial features, such as skeletal Class II or Class III facial profiles. These children do not sleep well at night due to obstructed airways; this lack of sleep can adversely affect their growth and academic performance. Many of these children are misdiagnosed with attention deficit disorder (ADD) and hyperactivity. It is important for the entire health care community (including general and pediatric dentists) to screen and diagnose for mouth breathing in adults and in children as young as 5 years of age. If mouth breathing is treated early, its negative effect on facial and dental development and the medical and social problems associated with it can be reduced or averted. Received: February 11, 2009 Accepted: May 5, 2009 The importance of facial appearances in contemporary society is undeniable. Many studies have shown that individuals with attractive facial features are more readily accepted than those with unattractive facial features, providing them with significant advantages. 1-6 However, many health care professionals (as well as the public) feel that individual facial features are the result of genetics and therefore cannot be altered or changed—in other words, the genotype ultimately controls the phenotype.

  • Orofacial Myology Is a Specialized Professional Discipline That Evaluates and Treats a Variety Of
    What is Orofacial Myology? Orofacial myology is a specialized professional discipline that evaluates and treats a variety of oral and facial (orofacial) muscles, (myo-) postural and functional disorders and oral habits that may disrupt normal dental development and also create cosmetic problems. The principles involved with the evaluation and treatment of orofacial Myofunctional disorders are based upon dental science tenets; however, orofacial Myofunctional therapy is not dental treatment. Myofunctional therapy can be basically described as correcting an oro-facial muscular unbalance, including correction of the position of the tongue at rest and during swallowing. Specific treatments involve establishing and stabilizing normal rest position of the tongue and lips, eliminating deviate (abnormal) oral habits and correcting swallowing patterns when tongue thrusting is involved. Improvements in appearance are observed during and following therapy. What are Myofunctional disorders and how are they corrected? An oral Myofunctional disorder includes a variety of oral habits, postures and functional activities that may open the normal dental bite or may lead to deformation of the dental arches. • Thumb and finger sucking • an open-mouth posture with lips apart • a forward rest posture of the tongue • Tongue thrusting during speaking and swallowing Above mentioned oral habits characterize Myofunctional disorders. Such disorders can lead to a disruption of normal dental development in both children and adults. The consequence of postural and functional variations involving the lips and tongue are associated with dental malocclusion, cosmetic problems, and deformities in the growth of the dental arches. How Prevalent Are Orofacial Myofunctional Disorders (OMD)? Research examining various populations found 38% have orofacial Myofunctional disorders and, as mentioned above, an incidence of 81% has been found in children exhibiting speech/articulation problems.

  • Guidelines Proposal for Clinical Recognition of Mouth Breathing Children
    original article Guidelines proposal for clinical recognition of mouth breathing children Maria Christina Thomé Pacheco1, Camila Ferreira Casagrande2, Lícia Pacheco Teixeira3, Nathalia Silveira Finck4, Maria Teresa Martins de Araújo5 DOI: http://dx.doi.org/10.1590/2176-9451.20.4.039-044.oar Introduction: Mouth breathing (MB) is an etiological factor for sleep-disordered breathing (SDB) during childhood. The habit of breathing through the mouth may be perpetuated even after airway clearance. Both habit and obstruction may cause facial muscle imbalance and craniofacial changes. Objective: The aim of this paper is to propose and test guidelines for clinical recognition of MB and some predisposing factors for SDB in children. Methods: Semi-structured interviews were conducted with 110 orthodontists regarding their procedures for clinical evaluation of MB and their knowledge about SDB during childhood. Thereafter, based on their answers, guidelines were developed and tested in 687 children aged between 6 and 12 years old and attending elementary schools. Results: There was no standardization for clinical recognition of MB among orthodontists. The most common procedures performed were inefficient to rec- ognize differences between MB by habit or obstruction. Conclusions: The guidelines proposed herein facilitate clinical recognition of MB, help clinicians to differentiate between habit and obstruction, suggest the most appropriate treatment for each case, and avoid maintenance of mouth breathing patterns during adulthood. Keywords: Mouth breathing. Airway obstruction. Craniofacial abnormalities. Introdução: a respiração bucal (RB) é um fator etiológico para os distúrbios respiratórios do sono (DRS) na infância. O hábito de respirar pela boca pode ser perpetuado mesmo depois da desobstrução das vias aéreas.

Received: 17 November 2020; Accepted: 9 December 2020; Published: 11 December 2020 Abstract: Modern terran life uses several essential biopolymers like nucleic acids, proteins and polysaccharides. The nucleic acids, DNA and RNA are arguably life’s most important, acting as the stores and translators of genetic information contained in their base sequences, which ultimately manifest themselves in the amino acid sequences of proteins. But just what is it about their structures; an aromatic heterocyclic base appended to a (five-atom ring) sugar-phosphate backbone that enables them to carry out these functions with such high fidelity? In the past three decades, leading chemists have created in their laboratories synthetic analogues of nucleic acids which differ from their natural counterparts in three key areas as follows: (a) replacement of the phosphate moiety with an uncharged analogue, (b) replacement of the pentose sugars ribose and deoxyribose with alternative acyclic, pentose and hexose derivatives and, finally, (c) replacement of the two heterocyclic base pairs adenine/thymine and guanine/cytosine with non-standard analogues that obey the Watson–Crick pairing rules.
