- Description:
- The function and structure of the ovipositor in Hymenoptera have been studied intensively, although there is a lack of information on the external sheaths. We provide here a contribution on the structure of the external sheaths of the ovipositor of the parasitic wasp Aphidius ervi, in particular the secretory structure is described for the first time. These glands are made up of a large epithelial structure that consists a single layer of large secretory cells that occupy most of the lumen of the valve and belong to gland cell class 1. Based on the different features of the glands, a lubricating and/or host marking function is hypothesized and discussed., Sara Ruschioni, Paola Riolo, Roberto Romani, Donatella Battaglia, Nunzio Isidoro., and Obsahuje bibliografii

- Type:

- Subject:
- matematika, mathematics, finitistic dimension, restricted injective dimension, tilting module, 13, and 51
- Language:
- English
- Description:
- We study the relations between finitistic dimensions and restricted injective dimensions. Let R be a ring and T a left R-module with A = EndRT. If RT is selforthogonal, then we show that rid \left ( T_{A} \right )\leqslant findim(A_{A})\leqslant findim \left ( _{R}T \right )+rid\left ( T_{A} \right ). Moreover, if R is a left noetherian ring and T is a finitely generated left R-module with finite injective dimension, then rid \left ( T_{A} \right )\leqslant findim(A_{A})\leqslant fin.inj.dim \left ( _{R}R \right )+rid\left ( T_{A} \right ). Also we show by an example that the restricted injective dimensions of a module may be strictly smaller than the Gorenstein injective dimension., Dejun Wu., and Obsahuje seznam literatury

- Language:

- Description:
- The localisation and distribution of the serotoninergic nerve elements was studied for the first time in the flatworm Chimaericola leptogaster (Leuckart, 1830) using immunocytochemical methodology and confocal laser scanning microscopy. The musculature was investigated by histochemical staining of actin filaments; scanning electron microscopy was used to identify the sensory structures on the worm's surface. Uniciliated, bi-ciliated and multiciliated sensory endings have been described on the worm's surface. The morphological data demonstrate the presence of circular, longitudinal and diagonal muscles that comprise the musculature of C. leptogaster in the anterior, median and posterior body regions. Well-developed radial and circular muscle fibres were also observed surrounding the genital pore, two vaginae and in clumps of the haptor. The study revealed the presence of biogenic amine, serotonin, in the central and peripheral nervous systems of C. leptogaster: in the neurons and fibres of the cephalic ganglia and ventral nerve cord, in the innervation of reproductive system compartments. The localised sites of the serotoninergic elements point to important roles of serotonin in monogenean reproductive processes and, possibly, in the regulation of muscle function., Natalya V.

- Language:

- Description:
- The mitochondrial genome of Saccharosydne procerus (Matsumura) is the first sequenced in the tribe Saccharosydnini (Hemiptera: Delphacidae: Delphacinae). In addition, the mitogenome sequence of Sogatella vibix (Haupt) (in Delphacini) is also sequenced. The Sa. procerus mitochondrial genome is 16,031 bp (GenBank accession no. MG515237) in length, and So. vibix is 16,554 bp (GenBank accession no. MG515238). The existence of purifying selection was indicated by the rate of nonsynonymous and synonymous substitutions. Three species of Delphacini, Laodelphax striatellus (Fallén), Sogatella furcifera (Horváth) and Nilaparvata lugens (Stål), are important pests of rice. The phylogeny of these three rice planthoppers based on the mitochondrial genome sequence was (L. striatellus + (So. vibix + So. furcifera)) + (N. muiri + N. lugens)., Yi-Xin Huang, Dao-Zheng Qin., and Obsahuje bibliografii

- Description:
- a1_The first molecular assessment of phylogenetic relationships of cladorchiid digeneans (superfamily Paramphistomoidea Fischoeder, 1901) from freshwater fishes based on 28S rDNA, ITS2 and cox1 sequences reveals the subfamilies Dadayiinae Fukui, 1929 and Kalitrematinae Travassos, 1933 as non-monophyletic, whereas Dadaytrema Travassos, 1931 represented by three species is monophyletic. Fourteen species of cladorchiids were found in characiform, perciform and siluriform fishes in the Neotropical Region (Brazil and Peru), with numerous new host and geographical records. The first scanning electron micrographs of seven species are presented. Two new species of dadayiine and one new species of kalitrematine paramphistomes are described. Microrchis macrovarium sp. n. from Pimelodella cristata (Müller et Troschel) (type host), Tetranematichthys quadrifilis (Kner) and Pterodoras granulosus (Valenciennes) in Brazil and Peru differs from all three congeners in that the testes are directly tandem, not oblique, and that the ovary, between the caecal ends, is widely separated from the testes. Pronamphistoma philippei sp. n. from Heros sp. in Brazil is distinguished from the type and only species, Pronamphistoma cichlasomae Thatcher, 1992, by the absence of the anterior collar-like expansion present in the type species, the presence of extramural rather than intramural pharyngeal sacs, and the unusual development of the dorsal and ventral exterior circular muscle fibre series in the acetabulum., a2_Pseudocladorchis romani sp. n. from P. granulosus (type host), Brachyplatystoma vaillantii (Valenciennes), Calophysus macropterus (Lichtenstein), Megalodoras uranoscopus (Eigenmann et Eigenmann) and Oxydoras niger (Valenciennes) in Brazil and Peru, is most similar to Pseudocladorchis nephrodorchis Daday, 1907 but differs in the shape of the testes (irregular, versus reniform in the latter species) and the size of the ovary (as large as, or larger than, the testes in the new species). The generic diagnosis of Pronamphistoma Thatcher, 1992 is amended. Dadaytremoides parauchenipteri Lunaschi, 1989 is transferred to Doradamphistoma Thatcher, 1979 as D. parauchenipteri (Lunaschi, 1989) comb. n. based on morphological and molecular evidence., Camila Pantoja, Tomáš Scholz, José Luis Luque, Arlene Jones., and Obsahuje bibliografii

- Language:
- English
- Description:
- An unusual combination of median nerve's variations has been encountered in a male cadaver during routine educational dissection. In particular, the median nerve was formed by five roots; three roots originated from the lateral cord of the brachial plexus joined individually the median nerve's medial root. The latter (fourth) root was united with the lateral (fifth) root of the median nerve forming the median nerve distally in the upper arm and not the axilla as usually. In addition, the median nerve was situated medial to the brachial artery. We review comprehensively the relevant variants, their embryologic development and their potential clinical applications. and K. Natsis, G. Paraskevas, M. Tzika

- Description:
- 70letá pacientka s generalizovaným nádorem prsu (T4, N1–2, MX, G2) byla v rámci stagingu odeslána na scintigrafii skeletu. Vstupní první vyšetření s 99mTc-MDP (Obr. 1) prokázalo dvě patologická ložiska zvýšené kostní přestavby (lebka, žebro) a bylo interpretováno jako generalizace do skeletu. Pacientka byla léčena chemoterapií (4x EC, 9x TXT). Poté byla provedena mastektomie s exenterací axily a resekcí prsního svalu, následně byl nasazen Tamoxifen. Později byla provedena radioterapie hrudní stěny lineárním urychlovačem (25x, celkem 50 + 16 Gy). Léčbu absolvovala ve stabilizovaném stavu, subjektivně se cítila dobře, efekt terapie byl hodnocen jako velmi dobrý. Kontrolní druhá scintigrafie skeletu (Obr. 2) provedená půl roku po skončení radioterapie prokázala mnohočetná ložiska zejména v lebce, páteři a pánvi, nález byl hodnocen jako výrazná progrese. V léčbě byl přidán denosumab (XGEVA), který však byl po jediné aplikaci vysazen pro nekrózu dolní čelisti. Další kontrolní třetí scintigrafie skeletu (Obr. 3) provedená po 5 měsících prokázala výraznou regresi nálezu, nově se objevilo ložisko v dolní čelisti v důsledku její nekrózy. Nález na kontrolní druhé scintigrafii jsme zpětně hodnotili jako flare fenomén., x, Otto Lang, Ivana Kuníková, and Literatura
