Rat sperm AS-A: subcellular localization in testis and epididymis and surface distribution in epididymal sperm
Springer Science and Business Media LLC - Tập 318 - Trang 353-363 - 2004
Apichart Ngernsoungnern, Wattana Weerachatyanukul, Arpornrad Saewu, Siriporn Thitilertdecha, Prasert Sobhon, Prapee Sretarugsa
In this study, we investigated the subcellular compartmentalization of arylsulfatase-A (AS-A) in the testis and epididymis as well as the surface distribution in rat epididymal sperm. Testicular AS-A was compartmentalized specifically to the area underneath the outer acrosomal membrane of the acrosomal granule and to the dorsal aspect of the sperm acrosome. Epididymal AS-A was synthesized in the e...... hiện toàn bộ
Atrial natriuretic peptide (ANP): a study of ANP and its mRNA in cardiocytes, and of plasma ANP levels in non-obese diabetic mice
Springer Science and Business Media LLC - Tập 267 - Trang 267-272 - 1992
Hiroharu Mifune, Syusaku Suzuki, Junichi Honda, Yuta Kobayashi, Yasutaka Noda, Yoshihiro Hayashi, Koshi Mochizuki
Atrial natriuretic peptide (ANP) levels in cardiocytes and plasma were examined by using immunohistochemistry, electron microscopy, and radioimmunoassay in non-obese diabetic mice (NOD). Cardiocyte ANP mRNA expression was measured by the polymerase chain reaction method. ANP immunoreactivity in the auricular cardiocytes was more prominent in hyperglycemic mice (NOD-h) than in normoglycemic mice (N...... hiện toàn bộ
Neutrophil evasion strategies by Streptococcus pneumoniae and Staphylococcus aureus
Springer Science and Business Media LLC - Tập 371 - Trang 489-503 - 2017
Megan L. Lewis, Bas G. J. Surewaard
Humans are well equipped to defend themselves against bacteria. The innate immune system employs diverse mechanisms to recognize, control and initiate a response that can destroy millions of different microbes. Microbes that evade the sophisticated innate immune system are able to escape detection and could become pathogens. The pathogens Streptococcus pneumoniae and Staphylococcus aureus are part...... hiện toàn bộ

Ultrastructural and morphometric study of the lung of the European salamander, Salamandra salamandra L.
Springer Science and Business Media LLC - Tập 191 Số 2 - Trang 343-356 - 1978

Specialised plasma membranes in the preovulatory follicle op the fowl
Springer Science and Business Media LLC - Tập 68 Số 1 - Trang 70-79 - 1965
G. M. Wyburn, H. S. Johnston, Robert Aitken
Intercellular bridges and division patterns of rat spermatogonia
Springer Science and Business Media LLC - Tập 127 - Trang 201-208 - 1972
P. B. Moens, V. L. W. Go
The pattern of intercellular cytoplasmic bridges between rat spermatogonia and between spermatocytes is illustrated from electron microscopy of serial sections. Clones, or syncytia, containing as many as 22 connected spermatogonia and as many as 74 connected spermatocytes were observed. The absence of closed rings of cells agrees with the observation that intercellular bridges are the result of in...... hiện toàn bộ
Possible involvement of putrescine in nucleolar formation in early embryos
Springer Science and Business Media LLC - Tập 194 - Trang 103-114 - 1978
Olle Heby, Hadar Emanuelsson
Continuous treatment of developing eggs of the polychete Ophryotrocha labronica with α-methylornithine, which inhibits synthesis of putrescine, led to arrest of development at gastrulation. The present ultrastructural analysis suggests that the arrest of development is due to failure to form nuclei, and thus reveals a possible role for putrescine in nucleolar formation. Further support for this co...... hiện toàn bộ
Adrenergic nerves to the dermal melanophores of the rainbow trout, Salmo Gairdneri
Springer Science and Business Media LLC - Tập 99 - Trang 430-434 - 1969
B. Falck, J. Müntzing, A. -M. Rosengren
The stellate processes and cell bodies of the dermal melanophores in the rainbow trout are intimately enclosed by a plexus of thin varicose nerves which display a specific catecholamine fluorescence. The nerves contain probably small amounts of noradrenaline and have the ability to take up and concentrate this amine. Denervation of the skin leading to dispersion of the melanophores causes the nerv...... hiện toàn bộ
The hypothalamus and neuropsychiatric disorders: psychiatry meets microscopy
Springer Science and Business Media LLC - Tập 375 - Trang 243-258 - 2018
Hans-Gert Bernstein, Henrik Dobrowolny, Bernhard Bogerts, Gerburg Keilhoff, Johann Steiner
The past decades have witnessed an explosion of knowledge on brain structural abnormalities in schizophrenia and depression. Focusing on the hypothalamus, we try to show how postmortem brain microscopy has contributed to our understanding of mental disease-related pathologic alterations of this brain region. Gross anatomical abnormalities (volume changes of the third ventricle, the hypothalamus, a...... hiện toàn bộ
