The mechanisms of cardiac myopathies, a kinetics approach: Leading review

The normal adult heart is a well maintained machine that has a mechanism for growth replacement of the sarcomere that is lost by natural degeneration. This process ensures the heart has the strength of contraction to function correctly giving blood supply to the whole body. Some of the force of contraction of the sarcomere is transmitted to its major protein titin where its strength results in unfolding of a flexible section and release of a growth stimulant. The origin of all the cardiomyopathies can be traced to errors in this system resulting from mutations in a wide variety of the sarcomeric proteins. Too much or chronic tension transfer to titin giving increased growth resulting in hypertrophic cardiomyopathy (HCM) and too little leading to muscle wastage, dilated cardiomyopathy (DCM). HCM can ultimately lead to sudden cardiac death and DCM to heart failure. In this paper I show (1) a collection of the tension/ATPase calcium dependencies of cardiac myofibrils that define the mechanism of Ca2+ cooperativity. (2) I then reintroduce the stress/strain relationship to cardiomyopathies. (3) I then review the cardiomyopathy literature that contains similar Ca2+ dependency data to throw light on the mechanisms involved in generation of the types of myopathies from the mutations involved. In the review of cardiomyopathy there are two sections on mutations, the first dealing with those disrupting the Ca2+ cooperativity, i.e. the Hill coefficient of activation, leading to incomplete relaxation in diastole, chronic tension, and increased growth. Secondly dealing with those where the Ca2+ cooperativity is not affected giving either increased or decreased tension transfer to titin and changes in sarcomere growth.

Journal of Pulmonary and Respiratory Research is good journal for respiratory research purposes. It takes 2-3 weeks maximum for review of the manuscript to get published and any corrections to be made in the manuscript. It needs good articles and studies to get publish in the respiratory medicine. I am really glad that this journal editors helped me to get my case report published.

I, Muhammad Sarwar Khan, am serving as Editor on Archives of Biotechnology and Biomedicine (ABB). I submitted an editorial titled, 'Edible vaccines to combat Infectious Bursal Disease of poultry' for publication in ABB. After submitting the manuscript; the services rendered by the management and technical personnel to handle and process the manuscript were marvelous. Plagiarism report was shared with me with complements before reviewers' comments, All steps including article processing and service charges were well taken care of keeping in view the author's interest/preference. All together, it was an encouraging and wonderful experience working with ABB personnel.

The Journal Clinical Nephrology provides a good opportunity for readers to stay updated in the field of clinical nephrology. Additionally - it provides a good opportunity for authors to publish their work. 1. Publication of the accepted manuscripts is sufficiently rapid. 2. The trust factor between the journal and me, as an author, is very important and well preserved. 3. Peer review process very rapid and effective.
