For some years now, biopolymers have attracted great interest from both academia and industry. Some of them have been investigated for a long time, such as rubbers [ 1 ], the interest in others, such as starch, cellulose [ 2 ] or PHA [ 3 ], is mainly being driven by ecology concerns. Chitin is somehow apart from this mainstreaming interest in biopolymers. Indeed, as the second major biopolymer worldwide after cellulose, it is mainly produced as a byproduct in shellfish industry.

Biopolymers like chitin and chitosan exhibit diverse properties that open up a wide-ranging of applications in various sectors especially in biomedical science. The latest advances in the biomedical research are important emerging trends that hold a great promise in wound-healing management products. Chitin and chitosan are considered as useful biocompatible materials to be used in a medical device to treat, augment or replace any tissue, organ, or function of the body. A body of recent studies suggests that chitosan and its derivatives are promising candidates for supporting materials in tissue engineering applications. This review article is mainly focused on the contemporary research on chitin and chitosan towards their applications in numerous biomedical fields namely tissue engineering, artificial kidney, skin, bone, cartilage, liver, nerve, tendon, wound-healing, burn treatment and some other useful purposes.

Chitin is the most abundant aminopolysaccharide polymer occurring in nature, and is the building material that gives strength to the exoskeletons of crustaceans, insects, and the cell walls of fungi. Through enzymatic or chemical deacetylation, chitin can be converted to its most well-known derivative, chitosan. The main natural sources of chitin are shrimp and crab shells, which are an abundant byproduct of the food-processing industry, that provides large quantities of this biopolymer to be used in biomedical applications. In living chitin-synthesizing organisms, the synthesis and degradation of chitin require strict enzymatic control to maintain homeostasis. Bacteria are considered as the major mediators of chitin degradation in nature. Chitin and chitosan, owing to their unique biochemical properties such as biocompatibility, biodegradability, non-toxicity, ability to form films, etc, have found many promising biomedical applications.

Offers a comprehensive guide to the isolation, properties and applications of chitin and chitosan. Chitin and Chitosan: Properties and Applications presents a comprehensive review of the isolation, properties and applications of chitin and chitosan. These promising biomaterials have the potential to be broadly applied and there is a growing market for these biopolymers in areas such as medical and pharmaceutical, packaging, agricultural, textile, cosmetics, nanoparticles and more. The authors - noted experts in the field - explore the isolation, characterization and the physical and chemical properties of chitin and chitosan. They also examine their properties such as hydrogels, immunomodulation and biotechnology, antimicrobial activity and chemical enzymatic modifications. The book offers an analysis of the myriad medical and pharmaceutical applications as well as a review of applications in other areas. In addition, the authors discuss regulations, markets and perspectives for the use of chitin and chitosan.

Chitin and Chitosan: Structure, Properties and Applications in Biomedical Engineering

Corresponding Author. This review characterizes the most common natural polysaccharides and the presence of huge structural tendencies for the production of biologically active compounds, which have innovative characteristics and functions of different applications, especially in the field of biomedicine. Their applications are also demonstrated, such as: biomedicine antioxidant, anti-bacterial, anti-fungal anti-viral, hepatoprotective, cardiovascular, anti-hypercholesterolemia, anti-parasitic, anti-diabetic, detoxification, anti-tumor and immunomodulating , agriculture, food industry, textile industry, and paper making. Interestingly, the relationship between biological activity and chemical structure is elucidated for glucan, chitin, chitosan molecules with various degree of acetylation DA and Mw.

 Soy Hulohot, - произнес убийца.  - Моя фамилия Халохот.  - Его голос доносился как будто из его чрева. Он протянул руку.

Нуматака решил, что ему необходима дополнительная информация. Выскочив из кабинета, он повернул налево по главному коридору здания Нуматек. Сотрудники почтительно кланялись, когда он проходил мимо. Нуматака хорошо понимал, что эти поклоны вовсе не свидетельствует об их любви к нему, они - всего лишь знак вежливости, которую японские служащие проявляют по отношению даже к самым ненавистным начальникам. Нуматака проследовал прямо на коммутатор компании. Все звонки принимались единственным оператором на двенадцатиканальный терминал Коренсо-2000. Телефонистка, державшая трубку у уха, мгновенно поднялась и поклонилась, увидев босса.

Лицо его было несчастным. - Я думал, вы из городского… хотите заставить меня… - Он замолчал и как-то странно посмотрел на Беккера.  - Если не по поводу колонки, то зачем вы пришли. Хороший вопрос, подумал Беккер, рисуя в воображении горы Смоки-Маунтинс. - Просто неформальная дипломатическая любезность, - солгал. - Дипломатическая любезность? - изумился старик. - Да, сэр.

Беккер достал из кармана бумажник. - Конечно, я буду счастлив тебе заплатить.  - И он начал отсчитывать купюры.

По мне, так поделом Стратмору. - Грег, - сказала Сьюзан, стараясь не показать своего возмущения, - этот черный ход позволял АНБ расшифровывать электронную почту, представляющую угрозу нашей безопасности. - Что ты говоришь? - Хейл невинно вздохнул.  - И в качестве милого побочного развлечения читать переписку простых граждан.

Можно ли ему доверять. А не заберет ли он ключ. Фонтейну нужно было какое-то прикрытие - на всякий случай, - и он принял необходимые меры.
