Photolysis and partial ozonolysis of guanidinated kappa-elastin led to the destruction of isodesmosine and desmosine up to 96.0 and 91.5% respectively. Simultaneously there was a 3.89-fold enrichment of the lysine content. Two lysine containing tripeptides and one dipeptide were isolated and characterized. Their amino acid sequences were Gly-Ala-Lys, Gly-Lys-Ala and Lys-Ala, respectively. 相似文献

There have been many advances in the medical world over time that have greatly contributed to ameliorating and prolonging human life. The employment of surgical anesthesia is arguably one of the greatest medical discoveries of all time, and has immensely broadened our ability to treat the ill. While Dr. Henry Jacob Bigelow (1818-1890) was not the inventor of anesthesia, he was the first to publish and advocate its use in the 19th century (Bigelow and Bigelow [1894] A Memoir of Henry Jacob Bigelow, Boston: Little, Brown, and Company; Harrington and Mumford [1905] The Harvard Medical School: A History, Narrative and Documentary, Vol 2, New York: Lewis Publishing Company). Bigelow also contributed to revolutionizing the fields of orthopedic and urologic surgery, publishing extensive research on subjects where there was previously very little knowledge, and even developing new techniques. He also impacted the field of neuropsychiatry in his publication regarding Phineas Gage. His contributions to the medical field have set him apart as one of the most influential and famous surgeons of America in the 19th century. Anatomically, he will be remembered eponymously for his iliofemoral ligament and septum in the femur. 相似文献

A homogeneous preparation of glycoprotein (apparent molecular weight 34,000) has been isolated from bovine ligamentum nuchae by treatment of the tissue with 5 M guanidine HCl and 2-mercaptoethanol. The preparation exhibits amine oxidase activity which is only marginally inhibited by beta-aminopropionitrile. 相似文献

Coexpression of Serotonin and Nitric Oxide in the Raphe Complex: Cortical Versus Subcortical Circuit
Yuefeng Lu Kimberly L. Simpson Kristin J. Weaver Rick C.S. Lin 《Anatomical record (Hoboken, N.J. : 2007)》2010,293(11):1954-1965
Several lines of evidence have implicated a direct reciprocal interaction between serotonin and nitric oxide (NO). The goal of this investigation was, therefore, to examine the coexpression of tryptophan hydroxylase (TPH; the rate limiting enzyme for the synthesis of serotonin) and neuronal NO synthase (nNOS) in the ascending cortical projecting raphe nuclei (B6–B9 subgroups), when compared with the descending spinal cord projecting raphe nuclei (B1–B3 subgroups). Our data demonstrated that: (1) a significant number of raphe‐cortical projecting neurons was identified not only in the midline subgroup of dorsal raphe (B6, 7) but also in the median raphe (B8), as well as in the supralemniscal nucleus (B9); (2) serotonergic cortical projecting neurons from these three raphe nuclei exhibited a high (>80%) percentage of coexpression with nNOS immunoreactivity; (3) similarly, serotonin transporter immunoreactive fibers in the medial prefrontal cortex were also double‐labeled with nNOS immunoreactivity; (4) in contrast, the descending spinal cord projecting raphe nuclei revealed only TPH but not nNOS immunoreactivity. Our present findings suggest the existence of a direct interaction between serotonin and NO in the ascending cortical projecting raphe system. In contrast, a different strategy appears to operate the descending spinal cord projecting raphe system. Anat Rec, 2010. © 2010 Wiley‐Liss, Inc. 相似文献

Knowledge of development is of crucial importance and can help clarify mechanisms of maldevelopment, but it must be properly validated. Concepts of development must be consistent with the anatomy seen in postnatal life. Such consistency is not always achieved. We have reviewed new and old accounts of cardiac embryology with regard to the definitive structure of the atrial septum. The key to understanding is to distinguish between folds of the atrial wall and true interatrial partitions. The flap valve of the oval foramen, and its inferior rim, are true septal structures, whereas the other rims, particularly the antero‐superior rim, are infoldings enclosing extracardiac fat. During embryonic life, the systemic venous tributaries must achieve entrance only to the right side of the primary atrium. Development of the pulmonary venous component is a late event, with the canalizing vein using the dorsal mesocardium to gain access to the left side of the atrium. Once the systemic venous tributaries have achieved their rightward shift, the primary septum, together with the mesenchymal cap, grows between the systemic and pulmonary venous orifices. Closure of the primary foramen is achieved by fusion of the mesenchymal cap of the primary septum with the atrioventricular endocardial cushions and the vestibular spine (an additional mesenchymal structure carried on the right side of the pulmonary venous orifice). The superior margin of the newly formed secondary foramen is produced by an infolding of the atrial walls. Historically these mechanisms received appropriate recognition, but not all receive their proper due in current writings. Clin. Anat. 12:362–374, 1999. © 1999 Wiley‐Liss, Inc. 相似文献
