In owls and the common potoo the nictitating membrane is situated on the dorsal edge of the eye. In these birds, the scleral ring bears an additional, previously undescribed bone of various forms and dimensions (1.4-6.8 mm of length and 0.8-3.3 mm of width), located on the trajectory of the tendon of the pyramidal muscle which is attached to the nictitating membrane. This bone has a groove that encloses the tendon of the pyramidal muscle, preventing it from separating from the sclera during contraction, as well as diverting the trajectory of the tendon to impede it from projecting itself over the cornea. In the ferruginous pygmy owl, Nacunda nighthawk, Pauraque, scissor-tailed nightjar, roadside hawk and domestic duck the additional bone was not seen. Based on the morphofunctional characteristics of the bone, we suggest that this bone should be named the scleral sesamoid bone.","PeriodicalId":6885,"journal":{"name":"Acta anatomica","volume":"163 4","pages":"201-11"},"PeriodicalIF":0.0,"publicationDate":"1998-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000046499","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20945316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of the study was to determine possible racial differences in the structure and attachments of the iliolumbar ligament. The present study also investigated the spatial orientation of the transverse process of the L5 vertebra since the ILL has been reported to attach to the transverse process. The measurements of the iliolumbar ligament were carried out with a digital vernier caliper while the transverse process angles were measured with an adjustable protractor. The ligament in black people was made up of a single, markedly longer band compared to white people, where the ligament was made up of two shorter bands. The ILL measured 61.8 +/- 1.3 mm in black and 33.2 +/- 1.5 mm white men, and in black women 61.3 +/- 0.9 mm versus 32.2 +/- 1.2 mm in white women (p <0.01). Further, the ILL was markedly wider in black than white subjects (p <0.01). The horizontal and vertical angle also varied greatly between black and white subjects (p <0.01). These are previously unrecognized observations. Albeit unsubstantiated, these findings may have implications for understanding the etiology of various low back stress problems.","PeriodicalId":6885,"journal":{"name":"Acta anatomica","volume":"163 4","pages":"218-23"},"PeriodicalIF":0.0,"publicationDate":"1998-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000046501","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20946361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Major progress has been made during the past two decades on structural identification of these antigens. None of these structures are truly 'tumor-specific'. However, many of the antibodies show preferential or 'specific' reactivity with tumors, based on organizational differences of membrane GSLs in tumor cells versus normal cells. Clustered GSL antigens organized with transducer molecules in microdomain have been found recently to comprise a structural and functional unit involved in tumor cell adhesion coupled with signal transduction. Some of the GSL antigens have been identified as adhesion molecules recognized by carbohydrate-binding proteins or by complementary carbohydrates on target cells. Such adhesion, coupled with signaling, may initiate the metastatic process. Elucidating the mechanism of this initial adhesion/signaling step may lead to discovery of therapeutic agents that disrupt adhesion ('antiadhesion therapy') or normalize signaling ('ortho-signaling therapy'). Tumor-associated GSL antigens are also a target in immunotherapy of tumors, including development of antitumor vaccines.","PeriodicalId":6885,"journal":{"name":"Acta anatomica","volume":"161 1-4","pages":"79-90"},"PeriodicalIF":0.0,"publicationDate":"1998-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000046451","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20693441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In all exocrine cell types of the gastric epithelium, actin filaments exhibit a polarized pattern of distribution. In the members of the mucus- and protein-synthesizing cell line, the actin filaments form a prominent barrier to the exocytosis of secretory granules underneath the apical membrane. Therefore, actin is supposed to be involved in the control of exocytosis. The basolateral subplasmalemmal cortex of the exocrine cells, however, shows weaker labeling for actin filaments. In this position actin might be responsible for the movement of epithelial cells along the length of the gastric gland during physiological cell renewal and for the maintenance of the integrity of the epithelial unit and of cell polarization. In parietal cells of bovine abomasum, actin filaments are, in addition, associated with the intracellular canaliculus, but not with the tubulovesicular compartment. We assume that actin filaments reorganize the canalicular membrane after membrane translocations in the course of acid secretion. For the first time, actin filaments were documented in the rare brush cell type of bovine abomasum, where they do not form a terminal web beneath the apical membrane and therefore point out the nonexocrine function of the brush cell type. In all polarized cells of the bovine abomasum, actin filaments underlay the two apical members of the junctional complex, the tight junction and the adherens junction, where they might be involved in the regulation of cell adhesion, cell motility and cell shape determination.","PeriodicalId":6885,"journal":{"name":"Acta anatomica","volume":"163 1","pages":"20-30"},"PeriodicalIF":0.0,"publicationDate":"1998-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000046442","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20761634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sample is comprised of 27 black males, 20 black females, 37 white males and 21 white females. Measurements of the SA were made with an adjustable protractor with an accuracy of ±1°. A new method using a specially designed instrument was developed for taking LSC measurements. A sliding scale that could be moved in the cranialcaudal direction was fitted with a measurement stick which measured the depth of the lumbar and sacral vertebral bodies (ventral to dorsal). The measuring device was placed on the autopsy table above the supine cadaver to measure these depths from the ventral side. The LSC was calculated as the mean difference between lumbar and sacral depths. The SA is smaller in black than in white men (43.6 ± 3.4 vs. 61.7 ± 2.1°, p <0.001). Similarly, black women have a smaller SA than white women (36.0 ± 2.2 vs. 50.2 ± 1.9°, p <0.001). The LSC is also larger in black than white men (9.4 ± 1.1 vs. 5.1 ± 0.3 cm, p <0.001), and black women also have significantly larger LSC compared to white women (13.2 ± 0.5 vs. 9.2 ± 0.6 cm, p <0.001). These data are so far the largest empirical evidence of differences in the SA and the LSC in young black and white cadaver specimens.","PeriodicalId":6885,"journal":{"name":"Acta anatomica","volume":"162 4","pages":"226-31"},"PeriodicalIF":0.0,"publicationDate":"1998-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000046437","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20742713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
