Supramolecular Devices

Supramolecular device includes hydrogel and polymer manufactured by gelation or polymerization. Hydrogels are produced via chemical and physical gelation. Polymers are synthesized through photopolymerization, step-growth, and chain-growth polymerization. The supramolecular device possesses as the host to entrap the guest molecules via chemical, physical and physical-chemical microencapsulation. The present review article discusses the microencapsulation techniques, mechanism of gelation or polymerization, and different gelation or polymerization methods with given examples, such as gelatin, chitosan, and polyvinyl alcohol (PVA), and polyamide to act as the hosts for encapsulation.

The Common

The core principles in Ayurveda give prime importance to Agni, Prakriti, Ahara (food) and Vihara (lifestyle) in maintaining health. Present era people are scheduled to one or the other works due to which they are following unrightful food and habits which lead the manifestation of one of the common disorder which troubles person a lot - Amlapitta. By excess “Hurry, Worry and Curry” GIT disorders are the most common, not only affecting physical health but also psychological and social health. Amlapitta is one of that and it is a burning problem of the whole World. Amalpitta is composed of word Amla and Pitta. Amlapitta is a very common disease caused by Vidagdha Pitta with features like Amlodgara, Tiktodgara, Hrit, Kantha Daha etc. Pathya recommended in Amlapitta are Yava, Godhuma, Purana Shali, Mudga Yusha, Lajasaktu etc. Apathya recommended in Amlapitta are Navanna, Avidugdha, Masha, Kulattha, Dadhi and etc. So this present review article throws light on Pathya (conducive) and Apathya (non conducive) in Amlapitta.

Polymer Chemistry: A Practical Approach in Chemistry has been designed for both chemists working in and new to the area of polymer synthesis. It contains detailed instructions for preparation of a wide-range of polymers by a wide variety of different techniques, and describes how this synthetic methodology can be applied to the development of new materials. It includes details of well-established techniques, e.g. chain-growth or step-growth processes together with more up-to-date examples using methods such as atom-transfer radical polymerization. Less well-known procedures are also included, e.g. electrochemical synthesis of conducting polymers and the preparation of liquid crystalline elastomers with highly ordered structures. Other topics covered include general polymerization methodology, controlled/"living" polymerization methods, the formation of cyclic oligomers during step-growth polymerization, the synthesis of conducting polymers based on heterocyclic compounds, dendrimers, the preparation of imprinted polymers and liquid crystalline polymers. The main bulk of the text is preceded by an introductory chapter detailing some of the techniques available to the scientist for the characterization of polymers, both in terms of their chemical composition and in terms of their properties as materials. The book is intended not only for the specialist in polymer chemistry, but also for the organic chemist with little experience who requires a practical introduction to the field.

Comprehensive Literature Review

Cholesterol Granulomas of the Maxillary Sinus, considered an unusual presentation at this anatomical site. Over last 2 decades, only few cases are reported in the literature (English) and no available comprehensive reviews or studies on this entity. Herein in this article we present a comprehensive literature review of the available reports of 16 cases along with reporting a new case which we managed, aided with its histopathological pictures. This review article can be a reference for practitioners in the field of otorhinolaryngology who may encounter these cases. Also, it attracts the attention to consider this pathology among the differential diagnoses of nasal masses. Moreover, including a described pathological imaging may help young pathologist to identify this pathology.

Context Immunohistochemistry has become an indispensable ancillary technique in anatomic pathology laboratories. Standardization of every step in preanalytic, analytic, and postanalytic phases is crucial to achieve reproducible and reliable immunohistochemistry test results. Objective To standardize immunohistochemistry tests from preanalytic, analytic, to postanalytic phases. Data Sources Literature review and Geisinger (Geisinger Medical Center, Danville, Pennsylvania) experience. Conclusions This review article delineates some critical points in preanalytic, analytic, and postanalytic phases; reiterates some important questions, which may or may not have a consensus at this time; and updates the newly proposed guidelines on antibody validation from the College of American Pathologists Pathology and Laboratory Quality Center. Additionally, the article intends to share Geisinger's experience with (1) testing/optimizing a new antibody and troubleshooting; (2) interpreting and reporting immunohistochemistry assay results; (3) improving and implementing a total immunohistochemistry quality management program; and (4) developing best practices in immunohistochemistry.

The purpose of this review is to provide the latest information on Down syndrome. The author conducted a literature search of available sources describing the issue of down syndrome with special focus on syndrome and made a comparison and evaluation of relevant findings.The results of this review indicate that Down syndrome (DS) is one of the commonest disorders with huge medical and social cost. DS is associated with number of phenotypes including congenital heart defects, leukemia, Alzeihmer’s disease, Hirschsprung disease etc. DS individuals are affected by these phenotypes to a variable extent thus understanding the cause of this variation is a key challenge. In the present review article, we emphasize an overview of DS, DS-associated phenotypes diagnosis and management of the disease.

Plants are not only the source of food, oxygen, and shelter, but the same are also a potential foundation of medicines. Many natural and plant-derived antimicrobial and wound healing compounds have been recognized. In the present review, we have studied the main bioactive components of Acacia catechu with their medicinal roles. Most of these bioactive components are secondary metabolites which are produced by plants as side products of certain physiological reactions and are of no use for the plant itself. These components have been reported for their medicinal properties. In this review, we have mentioned some antibacterial, antifungal, and wound healing properties of A. catechu with its known bioactive components. The aim of this review article is, to enlist the possible potent bioactive components of the plant, against pathogenic microbes that can replace the use of chemicals and synthetic antibiotics for the treatment of skin infections and other diseases.
