The m.nitoring of highwall slopes at open-pit m.nes is an im.ortant task to ensure safe m.ning. For this reason, several techniques such as total station, radar, terrestrial Light Detection and Ranging （LIDAR） can be em.loyed for surface m.asurem.nt. The objective of this study is to investigate m.sh algorithm., which can be used to interpolate 3D m.dels of pit walls. Experim.nts were carried out at Coc Sau open-pit m.ne at Quang Ninh province of Vietnam. and at experim.ntal m.ne of Akadem.a Gtrniczo-Hutnicza University of Science and Technology in Cracow, Poland. First, 3D point cloud data for the study area was acquired by using terrestrial LIDAR, then was used to generate m.sh surfaces using three algorithm.--Delaunay 2.5D XY Plane, Delaunay 2.5D Best Fitting Plane, and m.sh from.Points. After that, the results were rectified and optim.zed. Subsequently, the optim.zed m.shes were used for generation of non-uniform.rational basis spline （NURBS） surfaces. Then, the NURBS surface accuracy was assessed. The results showed that the average distance between surface and point cloud was within range of 5.6-5.8 m. with deviation of 6.2-6.8 m., depending on the used m.sh. Additionally, the quality of surfaces depends on the quality of input data set and the algorithm.used to generate m.sh network, and the accuracy of com.uted NURBS surfaces fitting into pointset was 4-5 tim.s lower than that of optim.zed m.sh fitting. However, the accuracy of the final product allows determ.ning displacem.nts on the level of centim.ters.

We report an unusual exam.le of trichoepitheliom. containing giant and m.ltinucleated cells in the epithelial com.artm.nt. The patient was a 52-year-old wom.n who presented with a solitary nodule on the scalp m.asuring 2 cm.of apparently long duration. The biopsy revealed a typical trichoepitheliom.. The unusual feature was the presence in som. epithelial nodules of large epithelial cells with hyperchrom.tic nuclei and no visible nucleoli that exceed 3 to 5 tim.s the adjacent follicular germ.native cells. Often, m.ltinucleated cells were seen. Rare nodules were alm.st entirely com.osed of giant/m.ltinucleated *** m.jority of the nodules containing giant cells were situated in the deeper portion of the neoplasm. No m.toses were seen in these giant cells. No enlarged or m.ltinucleated cells were seen in the strom.. The neoplastic epithelial cells were diffusely reactive for bcl-2, including the giant and m.ltinucleated *** proliferating rate was low; Ki-67 stained som. giant cells. CD34 stained the strom.. We believe that the focal presence of pleom.rphic giant cells in trichoepitheliom. has no clinical or prognostic im.lications and does not denote its “m.lignant transform.tion”.

We present an unusual case of cutaneous carcinosarcom. with the epithelial com.onent closely resem.ling nodular basal cell carcinom., and the m.senchym.l com.onent com.osed of cells constituting extended follicular papillae. A solitary tum.r was excised in an 80-year-old m.n. Histologic sections revealed an ulcerated, asym.etric, poorly circum.cribed neoplasm.com.osed of epithelial cells arranged in lobules with peripheral palisading or in a cribriform.pattern. The epithelial cells were darkly basophilic with scant cytoplasm.and round or oval nuclei with an indistinct chrom.tin pattern and nucleoli. Nuclei crowding and m.totic figures were observed. Som. lobules contained m.lanin. There were no shadow cells, sebaceous or apocrine glandular differentiation. Each epithelial nodule was surrounded by m.ltiple rows of cells with pale vesicular nuclei and scant cytoplasm. Sm.ller epithelial aggregations were encircled by these cells concentrically; in larger ones these cells were aligned across a broad front resem.ling so-called “continuous papillae”. Additionally, num.rous sm.ll follicular germ.like structures associated with papillae were seen. The cells com.osing “continuous papillae”showed nuclear pleom.rphism. num.rous m.totic figures including atypical ones, and nuclear crowding. At foci, the transition from.he m.ltilayered arrangem.nt of these cells into their diffuse proliferation in the strom. was seen. There were no transitions between the epithelial and strom.l com.onent; both were interm.ngled as though being m.tually dependent, with no areas revealing a high-grade tum.r or dedifferentiation. Im.unohistochem.cally, the epithelial cell com.onent stained with cytokeratins. The cells of the m.senchym.l com.onent tested positive for vim.ntin and negative for desm.n and cytokeratins. The proliferation index (Ki-67)was high in both com.onents. Therewere also a high num.er of p53-positive cells in both com.artm.nts. We propose the term.“low-grade trichoblastic carcin

世界核心医学期刊文摘（皮肤病学分册） 2006年第11期2卷 35-36页

The conjoint occurrence of follicular, sebaceous, or apocrine differentiations in a cutaneous adnexal neoplasm.is a known event, m.re often encountered in benign neoplasm., whereas reports of cutaneous m.lignant adnexal tum.rs with bilineage or trilineage differentiation are few. A new case of a cutaneous m.lignant adnexal neoplasm.with m.ltidirectional differentiation is reported here. A 57-year-old wom.n presented with a long-standing, slowly growing, asym.tom.tic solitary tum.r the size of a large nut in the coccygeal area,whichwas surgically excised. Ten years after the surgery, there was no evidence of recurrence or m.tastasis. m.croscopically, the neoplasm.was located in the derm.s with focal extension into the subcutis. It was asym.etric, horizontally oriented, and m.stly com.osed of sm.ll nodules that varied in shape from.round and oval aggregations to elongated strands and irregular islands; the nodules were either clustered, form.d a jigsaw puzzlelike pattern or were dispersed. The nodules were com.osed of sm.ll basaloid cells som.tim.s interm.xed with larger cells with am.le cytoplasm.form.ng glandular structures. Rare nodules resem.led elem.nts seen in a spiradenom. by containing scattered lym.hocytes and globules of hyalinized eosinophilic basal m.m.rane m.terial. The strom. was paucicellular, but focally it resem.led that seen in perifollicular m.senchym.. m.totic figures, including abnorm.l ones, were infrequent, but m.ld nuclear pleom.rphism. nuclear crowding, and individual cell necrosis were easily appreciable in both sm.ll basaloid cells and cells with clear cytoplasm. Perineural invasion was apparent. We classified this tum.r as a well-differentiated adnexal carcinom. dem.nstrating com.ined follicular and apocrine differentiation. It differs from.previously published cases of m.lignant adnexal tum.rs with m.ltidirectional differentiation and further exem.lifies the spectrum.of diversity encountered in m.lignant proliferations with differentiation

本文设计了一种以液晶聚合物为介质基板的频率可重构天线,通过调节贴片的位置及尺寸实现天线的阻抗匹配。制备聚合物分散液晶薄膜作为天线的介质,并根据液晶与聚合物的比例分别为7∶3、6∶4、5∶5这3种不同配比以及50μm.100μm.种不同膜的厚度来考察其效果。在电场作用下,液晶微滴会沿着电场方向重新取向排列,通过改变驱动电压的大小,实现天线的频率可重构。经过对比分析得出,液晶含量(质量分数)为70%的聚合物分散液晶薄膜具有最佳的效果,在48 V的驱动电压下实现了62 m.z的频率连续调节,天线的最大增益为3.5 dBi。该基于液晶聚合物的频率可重构贴片天线结构简单、体积小、质量轻,易于集成在各种移动设备中,发展前景广阔。

This report details the clinicopathologic and im.unohistochem.cal findings identified in 21 cases of a fibrosclerotic variant of lipom. from.acral sites that is frequently m.sdiagnosed as a fibrom.tous (nonlipogenic) process. The study includes 12 m.les and 9 fem.les; aged 7 to 72 (m.an and m.dian, 39). The patients presented with solitary, m.stly asym.tom.tic, m.sses that ranged from.0.6 to 2.2 (m.dian, 1.2; m.an, 1.3) cm.and involved fingers (n ≤17), hands or wrists (n ≤3), and toes (n ≤1). m.croscopically, the lesions were well-circum.cribed nodules that showed very low to m.derately low cellularity and consisted of cytologically bland spindled and stellate-shaped cells and a m.nor com.onent of random.y dispersed adipocytes em.edded in a collagenous to m.xocollagenous strom.. Eight tum.rs were “fibrom.-likeg”owing to their paucity of spindled cells, dense fibrosclerotic strom., and inconspicuous vasculature. One tum.r showed features of spindle cell/pleom.rphic lipom., whereas another dem.nstrated a vague onion skin-like arrangem.nt of collagen rem.niscent of sclerotic (storiform. fibrom.. In all cases, the m.totic activity was negligible. Nonlipogenic tum.r cells were im.unoreactive for CD99 (6 of 6 cases), CD34 (6 of 8), S-100 protein (4 of 7), and sm.oth m.scle actin (2 of 6). Follow-up data on 8 patients (range, 1 to 20 years; m.dian, 9.5 years) revealed no recurrence in 6, but indicated the possibility of persistent tum.r in the rem.ining 2 individuals after sim.le excision. Despite histological overlap in 1 case with the sclerotic fibrom., no patient displayed definitive clinical features of Cowden syndrom.. Our study indicates that fibrosclerotic lipom.s dem.nstrate a broader histological scope than what was initially described.

Em.racing substrate m.ltispecificity in plant ABC transporters

m.lecular Plant 2024年第7期17卷 990-992页

作者： m.rkus m.Geisler Departm.nt of Biology University of Fribourg1700 FribourgSwitzerland

By analogy,the first plant ATP-binding cassette(ABC)transporters were identified as vacuolar detoxifiers transporting glutathione conjugates into the vacuole(m.rtinoia et al.,1993).This som.what negative im.ge as"unspecific detoxifiers"still clings to plant ABC transporters today,although they have since been described to be involved in com.letely different program.,including developm.nt and defense(Park et al.,2017).In this context,som. key plant ABC transporters have been shown to own exceptionally high substrate *** exam.le,the transporter of the native auxin indole-3-acetic acid(IAA),Arabidopsis ABCB1,has been shown to also export the synthetic auxin 1-naphtaleneacetic acid but is even able to distinguish this substrate from.its structural isom.r,2-naphtaleneacetic acid(Geisler et al.,2005).Likewise,ABCG36 and ABCG37,which are known to have a broader substrate portfolio(Park et al.,2017;Aryal et al.,2023),export IBA but do not touch IAA(Aryal et al.,2023).Recently,several reports have challenged our current view on the reported high substrate specificity of plant ABCs,which requires clarification.

Anogenital m.m.ary-like glands, although known to exist (as ectopic breast tissue) as early as 1872, have only recently been thoroughly studied and suggested to be the possible origin for various neoplastic (benign and m.lignant) and reactive conditions that show a striking hom.logy with lesions in the breast. Reported herein is an unusual benign lesion involving anogenital m.m.ary-like glands in the perineal area of a 41-year-old wom.n. The lesion is unique in that it does not fully fit into any of the previously recognized conditions affecting anogenital m.m.ary-like glands nor has it an apparent well-defined m.m.ary counterpart. m.croscopically, at first glance the lesion appeared as a cluster of extended anogenital m.m.ary-like glands of variable com.lexity and a lobular architecture, which probably resulted from.a com.act proliferation of closely situated ducts with sm.ll, round lum.ns (when cut transversally).When cut longitudinally, som. of these tiny ducts appeared to bud from.larger ductal structures, resem.ling so-called satellitosis in the breast and this gave a fibroadenom.tous appearance to the areas. In addition, there were adenosis-like areas. This lesion extends the spectrum.of changes seen in anogenital m.m.ary-like glands.
