Taxonomy of the genus Lispe Latreille (Diptera: Muscidae) in Korea

In this paper, a total of four species of the genus Lispe are treated. Of these, L. assimilis Wiedemann and L. litorea Fallén are reported for the first time in Korea. A key to the Korean species, their domestic localities, and some illustrations are given.     

Courtship dances in the flies of the genus Lispe (Diptera: Muscidae): from the fly's viewpoint

Two predatory fly species, Lispe consanguinea Loew, 1858 and L. tentaculata DeGeer, 1776, inhabit the supralittoral zone at the shore of a fresh-water reservoir. Both species look alike and possess similar "badges," reflective concave silvery scales on the face. Flies occupy different lek habitats. Males of the first species patrol the bare wet sand on the beach just above the surf. Males of the second species reside on the more textured heaps of algae and stones. Courtship and aggressive behaviour of males was video-recorded and analysed frame by frame. Visual stimuli provided by the conspecific partner were computed in the body-fixed space of a fly observer. Males of L. consanguinea perform long pedestrian dances of pendulating circular arcs (frequency 2 s(-1), median radius 2.5 cm, linear velocity 0.130 m/s). Right and left side runs are equally probable. Circular runs are interrupted by standby intervals of average duration 0.35 s. The female views the male as a target covering 2 by 2 ommatidia, moving abruptly with the angular velocity over 200 degrees/s in a horizontal direction down the path of about 50 degrees till the next standpoint. Dancing is evenly distributed around the female. On the contrary, the male fixates the image of the female within the narrow front sector (median +/-10 degrees); the target in his view has 6-7 times less angular velocity and angular span of oscillations, and its image in profile overlays 6-8 by 2 ommatidia. If the female walks, the male combines tracking with voluntary circular dances. Rival males circle about one another at a distance shorter than 15 mm, but not in close contact. Males of L. tentaculata are capable of similar circular courting dances, but do so rarely. Usually they try to mount any partner immediately. In the latter species, male combat consists of fierce wrestling. Flies of both species often walk sideward and observe the partner not in front but at the side.     

Lispe patellitarsis Becker (Diptera: Muscidae) new to Korea

Lispe patellitarsis Becker is identified for the first time in Korea. Diagnoses and illustrations of the habitus and male genitalia are given.     

Revision of the Lispe longicollis-group (Diptera,?Muscidae)

The Lispe longicollis species-group is revised. Lispe ethiopica sp. n. is described. The following 3 new synonyms are established: Lispe assimilis Wiedemann, 1824 (syn: cyrtoneurina Stein, 1900 and modesta Stein, 1913); Lispe manicata Wiedemann, 1830 (syn: forficata Kurahashi & Shinonaga, 2009). Female of Lispe microptera Seguy, 1937 is described for the first time. Identification key for known Eurasian and African species is given.     

A molecular phylogeny for the frog genus Limnodynastes (Anura: myobatrachidae)

Members of the genus Limnodynastes are a prominent and widespread feature of the Australian frog fauna. Yet despite their potential to be informative about biogeographic history and mechanisms of speciation, the relationships among these taxa are not well known. We investigated phylogenetic relationships within the genus Limnodynastes via sequencing of mitochondrial (mt)DNA from current members of the genus Limnodynastes and the monotypic genus Megistolotis. a 450-bp fragment of the 16S rRNA gene and a 370-bp fragment of the protein-coding gene ND4 were used to infer a molecular phylogeny. We revise traditional species groupings and now recognize four species groups within Limnodynastes: the L. ornatus group (L. ornatus and L. spenceri), the L. peronii group (L. peronii, L. tasmaniensis, L. fletcheri, the L. depressus), the L. salmini group (L. salmini, L. convexiusculus, and L. lignarius), and the L. dorsalis group (L. dorsalis, L. terraereginae, L. dumerilii and L. interioris). The L. ornatus species group forms a highly distinctive clade that is a sister group to the other Limnodynastes groups. Pending broader phylogenetic studies it could be removed from the genus Limnodynastes. Our results concur with previous suggestions that Megistolotis lignarius is nested within Limnodynastes, and we therefore reclassify this species as Limnodynastes lignarius. Furthermore, specimens identified as L. depressus form a mtDNA lineage distinct from other species in the genus, confirming the validity of the species. Specimens of species from the L. dorsalis group (L. dorsalis, L. dumerilii, L. interioris, and L. terraereginae) are closely related such that L. dumerilii is paraphyletic with two other species. Finally, our study provides broad support for previous phylogenies based on microcomplement fixation.

扇贝裙边糖氨聚糖对泡沫细胞形成过程中血管内皮生长因子表达的影响

目的:研究扇贝裙边糖氨聚糖时氧化低密度脂蛋白(ox-LDL)诱导的U937细胞泡沫化过程中血管内皮生长因子(VEGF)的影响,探讨其抗动脉粥样硬化作用的机理。方法:采用U937细胞与80mg/L的ox-LDL孵育48h建立U937泡沫细胞模型。将培养的U937细胞随机分为六组,正常对照组、模型组(ox-LDL)、肝素对照组(ox-LDL加100mg/L肝素)和低、中、高浓度的SS-GAG药物组(ox-LDL加200mg/L,400mg/L,800mg/L的SS-GAG)。采用酶联免疫吸附实验(ELISA)检测细胞分泌的VEGF的量,观察不同浓度SS-GAG对U937细胞泡沫化过程中VEGF表达量的影响。结果:培养的U937泡沫细胞中VEGF的表达量明显高于正常U937细胞(P＜0．01),而加入SS-GAG的药物组和肝素对照组则有不同程度降低,以800mg/mL药物组降低最为明显(P＜0．01)。结论:泡沫细胞形成过程中伴有VEGF的高表达,SS-GAG能够抑制其表达从而发挥抗动脉粥样硬化作用。

脊柱-骨盆固定系统的生物力学研究

目的:研究髂骨钉在脊柱-骨盆固定系统中对腰骶稳定性及螺钉应力分布的影响。方法:6具成人腰椎-骨盆防腐标本,分别按照三种不同的固定方式完成置钉连接操作,制成3个实验组:单纯腰椎后路长节段固定组(L2-L5组)、腰骶固定组(L2-S1组)、髂骨钉固定组(L2-S1-I组)。生物力学测试采用8 N·m纯力矩执行前屈、后伸、左右侧弯、左右旋转6个工况运动,比较各固定组L2、L5水平活动度以及L5椎弓根钉、S1螺钉应力。结果:L2-S1组、L2-S1-I组内固定系统以及腰骶关节活动度均明显降低(P0.05),L2-S1-I组的优势更加显著,尤其在抵抗固定系统旋转活动以及腰骶关节前屈活动时作用更明显。L2-S1-I组、L2-S1组L5椎弓根钉应力均较L2-L5组明显减小(P0.05);L2-S1-I组S1螺钉应力较L2-S1组显著减小(P0.05)。结论:髂骨钉技术能够提供良好的脊柱-骨盆固定效果,在维持腰骶稳定性方面优势明显;对近端固定螺钉有保护作用,在与S1螺钉联合使用时,能有效分担S1螺钉所受应力,显著降低螺钉松动、拔出的风险。     

Effect of daylength on the rate of recovery of photosensitivity in male starlings (Sturnus vulgaris).

Four groups of castrated photorefractory starlings were transferred from a photoperiod of 18 h light/day (18 L) to photoperiods of 6 L, 8 L, 11 L or 12 L. A control group was kept on 18 L. Plasma concentrations of luteinizing hormone (LH) were low in all groups initially. The first significant increase in LH, which signals the recovery of photosensitivity, occurred after 4 weeks in the groups on 6 L and 8 L, after 8 weeks in the 11 L group and after 13 weeks in the 12 L group. There was no increase in the group on 18 L. The rate of recovery of photosensitivity is therefore inversely proportional to daylength, for daylengths between 8 L and 12 L.
