• Better-than-Bo tox: Are Wrinkle Creams Effective?: The effects of wrinkle creams are visible only after a few weeks of their usage. One must not expect overnight results after using a skin care product. Wrinkles are not that easy to deal with. Our skin requires two essential proteins -- Collagen and Elastin to retain our youthful look.

• Cardiac dilatation associated with collagen alterations: There is a complex collagen network in the heart. Various components have been identified and generally on the basis of form and position some functions have been ascribed to one or another of these components. Since the various components all appear to be connected in a hierarchial network of some type assigning function is not difficult but demonstrating a given function is somewhat hazardous. We have demonstrated that two I.V. infusions of disulfide reagents one week apart activates a collagenolytic system that results in near complete loss of the collagen struts that interconnect myocytes, the collagen struts that connect capillaries to all adjacent myocytes and the weave complex that surrounds groups of myocytes. Increases in pre load or afterload result in responses indicating that the disulfide treated animals generate pressure equal to or greater than the control hearts, thus, the treatment has no affect on either myocyte contractility or force delivery to the ventricle.

• Morphology, composition, and function of struts between cardiac myocytes of rat and hamster: (a) the attachments of struts to the collagen weave of the sarcolemma, often lateral to the level of Z bands, (b) the presence of collagen type I in a composite material arrangement, (c) the relative dispositions and configurationa l changes of struts and myocyte surfaces in various physiological states and induced, non-physiologi cal perturbations of cardiac muscle, (d) the corrugated sarcolemmas with infoldings near Z bands, and (e) the continuity of intracellular filaments from Z bands to the inner aspect of the sarcolemma in relaxed and contracted myocytes.

• Structure and function of myocardial fibrillar collagen: The extracellular collagen matrix of the myocardium plays an important role in maintaining muscle fiber and cardiac alignment and ventricular shape and size. It also influences tissue and ventricle stiffness. This network consists of an organized hierarchy of collagen that is intimately associated with individual and groups of myocyte and muscle fibers, as well as the coronary vasculature. In renovascular and genetic hypertension, the hypertrophic response of the myocardium includes an increase in collagen concentration, thickening of existing fibrillar collagen, and addition of newly synthesized collagen to all of the matrix components. The consequences of this remodeling are a stiffer myocardium and left ventricular diastolic dysfunction. With removal of less than half of the normal amount of collagen the opposite occurs. That is, the ventricle dilates and there is an increase in ventricular compliance. Thus an abnormal accumulation of collagen is a major distinguishing factor betwee
• The collagen matrix of the heart. [Fed Proc. 1981] - PubMed Result: Scanning electron microscopy demonstrates an extensive and highly organized network of collagen in the left ventricle of all species examined. This system is arbitrarily divisible into three major components: a collagen weave network that surrounds groups of myocytes; an extensive array of collagen struts measuring 120 to 150 nm in diameter that extend from the basal lamina of a myocyte to the basal laminae of all contiguous myocytes; and an array of similar sized collagen struts that extend from the basal lamina of all capillaries to the basal laminae of all contiguous myocytes. The functions of the individual components of this complicated network are not well-defined. The weave network certainly contributes to the viscous and elastic properties of the heart. Myocyte-to-myo cyte struts can prevent slippage of adjacent cells during the cardiac cycle and would ensure equal stretch of adjacent myocytes during diastole. Myocyte to capillary struts may be important in maintaining capillary
