Cyclic Changes of Nerve Fibers in Human Endometrium  [PDF]
Tatsuo Tomita, Kuni Mah
Open Journal of Pathology (OJPathology) , 2014, DOI: 10.4236/ojpathology.2014.42011
Abstract:

Objective: The presence of nerve fibers in human endometrium remains unsettled but recent immunocytochemical studies have shown that there was increased innervation in the endometrium from women with endometriosis and some nerve fibers in the normally cycling human endometrium. In the current study, we used uterine tissue cryosections from normal cycling women, which previously provided better immunocytochemical staining for lymphatic vessels than in paraffin sections. Materials and Methods: A total of 16 cases from normally cycling women were included representing menstrual, early proliferative, early to late secretary phase. Neurofilament and CD 56 were used as immunocytochemical markers for nerve fibers with cryosections. Results: There were consistent presence of nerve fibers in myometrium and basalis. Few small nerve fibers were identified in early proliferative endometrium and more nerve fibers were present in lower-half functionalis from mid-secretary phase. Late-secretary functionalis showed less nerve fibers in the upper-half than the lower-half functionalis, implying growing nerve fibers from lower functionalis to upper functionalis in late-secretary phase. Conclusion: Nerve fibers appeared to cyclically grow from basalis to lower functionalis and then from lower functionalis to upper functionalis concomitantly with blood vessels in normally cycling human endometrium. These cycling endometrial nerve fibers consisted mostly of nonmyelinated small nerve fibers, which may transmit pelvic pain in the normally cycling women.

Cyclic Changes of Lymphatic Vessels in Human Endometrium  [PDF]
Tatsuo Tomita, Kuni Mah
Open Journal of Pathology (OJPathology) , 2014, DOI: 10.4236/ojpathology.2014.41002
Abstract:

Objective: The presence of lymphatic vessels in endometrium has been controversial and recent immunocytochemical studies with routinely paraffin embedded sections revealed lymphatic vessels in basalis and occasionally in functionalis. We aimed to investigate endometrial lymphatic vessels by immunocytochemical staining using cryosections, which provided better and consistent immunostaining for lymphatic vessels with a lymphatic marker, D2-40. We aimed further to explore the structure-function relationship of lymphatic vessels in the menstrual cycle. Materials and Methods: Sixteen cases of endometrium from menstrual, early-proliferative to latesecretary phase were immunostained for D2-40 and lymphatic vessels were morphometrically analyzed for functionalis, basalis and myometrium, respectively. Results: Lymphatic vessels were consistently most numerous in myometrium, followed by basalis in all phases whereas menstrual endometrium showed small, fragmented aggregates of lymphatic vessels in thin basalis. Earlyto mid-secretary endometrium revealed many lymphatic vessels in basalis and lower-functionalis with few lymphatic vessels in upper-functionalis. Late-secretary endometrium revealed more lymphatic vessels in upper-functionalis with dilated walls, which then burst at the surface of functionalis. Conclusions: These degenerating lymphatic vessels with markedly dilated lumen in upper-functionalis may contribute to lymphatic leakage in late-secretary phase. These immunostained lymphatic vessels in functionalis support proliferating and degenerating lymphatic vessel cycle synchronized with the menstrual cycle of endometrial arteries to maintain adequate fluid leakage.

Cyclic Changes of Lymphatic and Venous Vessels in Human Endometrium  [PDF]
Tatsuo Tomita, Kuni Mah
Open Journal of Pathology (OJPathology) , 2014, DOI: 10.4236/ojpathology.2014.44025
Abstract: Context: Cyclic changes of endometrial arteries are well established but possible cyclic changes of lymphatic and venous vessels have not been fully documented. There are no published morphological reports to support cyclic changes of endometrial lymphatic and venous vessels. Objective: Using cryosections of human endometrium, this study aimed to unveil possible cyclic changes of lymphatic and venous vessels. We previously reported cyclic changes of lymphatic vessels in human endometrium using D2-40. Design: A total of 16 cases representing menstrual, proliferative and mid and late secretary phase were studied. For Immunocytochemical staining, lymphatic vessel endothelial hyaluronan receptor 1 and von Willebr and factor were used for lymphatic and venous vessels, respectively. We used polyclonal LYVE-1 in this study, which revealed more lymphatic vessels than using D2-40. Results: Residual lymphatic and venous vessels were present in menstrual basalis. In Day 5 - 9 endometrium, there were sparse lymphatic vessels but were numerous growing venous vessels in thin proliferating functionalis. In Day 14 - 22 endometrium, there were scattered lymphatic vessels and numerous venous vessels in functionalis. In Day 25 - 26 endometrium, there were many dilated lymphatic vessels and numerous dilated, disintegrating venous vessels in upper functionalis than lower functionalis. Conclusion: The above findings support that lymphatic vessels are sparse but venous vessels are numerous in early proliferative functionalis. Lymphatic vessels grow from basalis to thin functionalis. In premenstrual phase, lymphatic vessels proliferate from lower to upper functionalis, and both lymphatic and venous vessels disintegrate for shedding by this immunocytochemical study using lymphatic and venous markers. Thus, all lymphatic, venous and arterial vessels undergo menstrual cyclic changes and shed for menstruation.
Der K rper als KulturproduzentIn The Body as Cultural Producer

Abstract: The Body is the Message": Gabriele Kleins Untersuchung Electronic Vibration fokussiert den tanzenden K rper als Medium einer sthetisch formulierten, sozialen Mimesis. Im Techno, so die These der Autorin, funktioniert Tanz als Aneignung, in deren Vollzug Musikkonsum in (pop)kulturelle Praxis umschl gt. Der K rper ist damit nicht nur Zeichentr ger, sondern wird selbst zum Ort und Agens von Kulturproduktion. "The Body is the Message”. Gabriele Klein’s book Electronic Vibration analyses the dancing body as a site of an aesthetically processed social mimesis. In techno and rave culture, says Klein, dancing functions as a process of appropriation, by which the consumption of music is being transformed into a (pop-)cultural practice. Thus, rather than being reduced to a signifier of culture, the dancing body has to be understood as a site of cultural production as well as an agent thereof.

Abstract: In einem Reprint der Originalausgabe von 1919 endlich wieder zug nglich gemacht, empfiehlt sich Lu M rtens kleine Schrift Die Künstlerin nicht nur als Beitrag zur Vor- und Frühgeschichte der feministischen Kunstwissenschaft. Als historisch-kritische Analyse der konomie künstlerischer Arbeit unter besonderer Berücksichtigung der Geschlechterdifferenz kann das Büchlein auch für aktuelle Debatten wichtige Denkanst sse liefern. Lu M rten’s essay, Die Künstlerin, now available as a reprint of the first edition published in 1919, is to be recommended not only as an important contribution to feminist art history avant la lettre. Moreover, the historical-critical analysis of the economy of artistic production which pays special attention to gender differences offers plenty of inspiration for current debates and reflections.

Kreuz- und Que(e)rfahrerinnen im Cyberspace. Sch ne Neue Welt, revisited Navigators in Cyberspace

querelles-net , 2003,
Abstract: Obgleich sich um die Frage nach einer feministischen Eroberung des Cyberspace in den vergangenen Jahren nicht nur ein breites Feld streitbarer Diskurse gebildet hat, sondern mittlerweile auch eine Reihe markanter Mythen ranken, wird sie sowohl vom Mainstream der akademischen Medientheorie als auch von den Protagonisten der popul ren Cyberkultur nach wie vor allenfalls als Marginalie verhandelt. Ob Bücher genderspezifische Bildungslücken schlie en k nnen, sei einmal dahingestellt. Mit reload. rethinking women + cyberculture haben die Multi-Media-Künstlerin Mary Flanagan und die Gender-Medien-Theoretikerin Austin Booth jedenfalls einen Sammelband vorgelegt, der nicht nur Betriebsblinden und Ein ugigen hinreichend Stoff zum Nachlesen und Nachdenken bietet, sondern in seiner Kombination aus feministischer Cyberfiktion und kritischen Essays zu Utopien und Realit ten der zeitgen ssischen Cyberkultur spannende Querverbindungen zwischen Theorie und Praxis herzustellen verspricht. In recent years there have been a number of debates and quite a few myths about feminist usage (if not conquest!) of cyberspace. Nonetheless, feminist cyber culture continues to be marginalised both within mainstream media theory and within discourses about popular cyber culture. This is about to change: The anthology Reload, edited by multi-media artist Mary Flanagan and gender studies/media studies scholar Austin Booth, offers plenty of food for thought for a wide audience. The different pieces range from feminist cyber fiction to critical essays on utopias and realities of contemporary cyber culture, cleverly connecting theory and practice.
Characterizing a Populated Riparian Zone  [PDF]
Darrien Yau Seng Mah
Open Journal of Ecology (OJE) , 2014, DOI: 10.4236/oje.2014.410050
Abstract:

Developments adjacent to river, over the years, have impacted the ecological systems along riparian zones. This paper is to explore the changes occurring in a populated riparian zone. For over 35 years, the nipah swamps along the study site at the edge of Kuching city, Sarawak, Malaysia are subjected to human disturbances. Once a nipah forest is dominated by Nypa fruticans, the study site is being replaced by Sonneratia caseolarisa mangrove forest. Both plants are indigenous to Southeast Asia region. We observe in the study site that Nypa fruticans, habitually a dominant species, is weakened when human disturbances are high, and leads to event taken over by Sonneratia caseolaris. We point out that Sonneratia caseolaris behaves intrusively rather than neighborly in disturbed systems. Here, we suggest that the plant also has high resistance towards human disturbances. This is a growing behavior contradictory to reports of Sonneratia caseolaris in natural systems.

Preliminary Evidence for a Second -525-545 Ma old Event of Granilate Facies Metamorphism in the Mozambique Belt of Tanzania and its Implication for a Two-Stage Model for Gondwana Assembly

Tanzania Journal of Science , 2000,
Abstract: Garnets from two samples of the Kitumbi granulites in the Mozambique Belt of north eastern Tanzania yield Sm-Nd ages of 525±15 Ma and 545±15 Ma. At the 95% confidence level, these ages are younger than the 576 ±15 to 634±16 Ma (Mean 606±12 Ma) ages previously reported from the more extensive Eastern Granulites. The Kitumbi garnets are therefore interpreted as dating cooling from a granulite facies event that is distinctly younger than the 630-700 Ma event that produced the Eastern Granulites. Unlike the Eastern Granulites, the Kitumbi rocks occur as small enclaves not separated from the surrounding amphibolite facies gneisses by any obvious structural discontinuity, lack the continental margin geochemical signatures that characterise the Eastern Granulites and yield late Archean depleted mantle crustal formation ages, similar to those obtained from the surrounding gneisses. These characteristics suggest that, unlike the Eastern Granulites that are isotopically exotic slices emplaced onto the surrounding amphibolite facies gneisses, the Kitumbi granulites are products of ~550 Ma old in situ granulite facies metamorphism of the surrounding country rocks. The existence of a regional granulite facies event at ~530-550 Ma offers a way of reconciling the palaeomagnetic and petrological/geochronological evidence for Gondwana assembly. Thus, as has been previously proposed by Meert et al. (1995), the 630-700 Ma old event that produced the Eastern Granulites may record regional crustal thickening arising out of collision of India, Madagascar, parts of Easten Antarctica and the Kalahari craton (IMSLEK terranes) with the Congo craton and the Arabian Nubian Shield (ANS). The younger granulite event recorded in the Kitumbi area could then mark a younger collision between Australo-Antarctica and the combined IMSLEK-Congo-ANS collage marking the final assembly of Gondwana.

The geochemistry of banded iron formations in the sukumaland greenstone belt of Geita, northern Tanzania: evidence for mixing of hydrothermal and clastic sources of the chemical elements

Tanzania Journal of Science , 2001,
Abstract: Major and trace element compositions of samples of Banded Iron Formations (BIF) from the Neoarchaean Sukumaland Greenstone Belt of Geita in northern Tanzania reveal that the BIF precipitated from hydrothermal solutions. Fe-Ti-Al-Mn systematics suggest that the hydrothermal deposits have been contaminated, by up to 20% by weight, with detrital material having a composition similar to modern deep-sea pelagic clays. SiO2 and Fe2O3 contents are 48.2 to 88.5% and 8.9 to 49.1% respectively. Al2O3 contents lie between 0.33 and 2.1% and show no correlation with either Fe2O3 or SiO2. Al2O3 is, however, positively correlated with Ti, Ga, Hf, Rb,Th, Zr and Sr but not with CaO, the alkalies and the total Rare Earth Elements (REE). The other major element oxides are generally present in negligible amounts. The samples are characterised by mean Zr/Hf and 144Sm/143Nd ratios of 48± 5 (2 SE) and 0.10±0.01 (2 SE) respectively, similar to mean upper continental crustal values. Shale-normalised REE patterns are nearly flat, except for small positive Eu and very slight negative Ce anomalies and reveal that, compared to average upper crust, the abundances of the REE in the BIF are up to an order of magnitude lower. Chondrite-normalised patterns are characterised by light (L) REE enrichment, flat to slightly depleted heavy (H) REE, slightly positive Eu anomalies and very small negative Ce anomalies. The HREE-depleted patterns are similar to patterns derived from granite-dominated upper continental crust and indicate that the bulk of the REE in the Geita BIF can not have been derived from a mixture of Neoarchaean sea water and bottom hydrothermal solutions. The trace element data, and the REE in particular, indicate that, despite their relatively low proportions, granitic detritus probably derived from contemporaneous felsic flows and pyroclastics are the cause of the dominant trace element geochemical signature of the BIF.
