During investigations of gill ectoparasites (Platyhelminthes) parasitising freshwater fish from Central America (Guatemala, Honduras, El Salvador and Panama) and southeastern Mexico (Guerrero, Oaxaca and Chiapas), the following dactylogyrid monogenoidean were found: Urocleidoides simonae sp. n. from Profundulus punctatus (Günther) (type host), Profundulus balsanus Ahl, Profundulus guatemalensis (Günther), Profundulus kreiseri Matamoros, Shaefer, Hernández et Chakrabarty, Profundulus labialis (Günther), Profundulus oaxacae (Meek), Profundulus sp. 1 and Profundulus sp. 2 (all Profundulidae); Urocleidoides vaginoclaustroides sp. n. from Pseudoxiphophorus bimaculata (Heckel) (type host) and Poeciliopsis retropinna (Regan) (both Poeciliidae); and Urocleidoides vaginoclaustrum Jogunoori, Kritsky et Venkatanarasaiah, 2004 from P. labialis, Profundulus portillorum Matamoros et Shaefer and Xiphophorus hellerii Heckel (Poeciliidae). Urocleidoides simonae sp. n. differs from all other congeneric species in having anchors with well-differentiated roots, curved elongate shaft and short point. Urocleidoides vaginoclaustroides sp. n. most closely resembles U. vaginoclaustrum, but differs from this species mainly in the shape of its anchors (i.e. evenly curved shaft and short point vs curved shaft and elongate point extending just past the tip of the superficial anchor root). The complexity of potential hosts for species of Urocleidoides and their effect on its distribution on profundulid and poeciliid fishes are briefly discussed., Edgar F.

Koncept chování typu C definovala Lydia Temoshoková v roce 1981. Chování typu C je charakterizováno potlačováním a neprojevováním negativních emocí, zvláště pak hněvu, zachováváním zdání klidu a příjemnosti a orientací na potřeby druhých více než potřeby osoby samotné. Celosvětově však dochází k zaměňování pojmů „chování typu C“ za neadekvátně užívaný pojem „osobnost typu C“ či „cancer-prone personality“. Toto stanovisko si dovolujeme tak jasně postulovat na základě konzultace s autorkou pojmu, Lydií Temoshokovou. Misinterpretace pojmu chování typu C vedla také k přesvědčení, že tento typ chování může jedince predisponovat ke vzniku nádorového onemocnění. Avšak koncept chování typu C popisuje copingovou strategii, která má, dle dosavadních výzkumů, vliv na rychlejší progresi nádorového onemocnění a onemocnění HIV následkem ovlivňování funkce imunitního systému. Diskutujeme obtíže s výzkumem chování typu C a představujeme metodu Vignette Similarity Rating Method (VSRM) vyvinutou Lydií Temoshokovou jako možný nástroj k výzkumnému zachycení chování typu C., The Type C concept was first described by Dr. Lydia Temoshok in 1981. The Type C is characterized by suppression and non-expression of negative emotions, especially by suppressing anger, maintaining a facade of contentment and being more concerned about the needs of other people than about one’s own needs. The term „Type C“ has been worldwide confused with inadequate terms „Type C personality“ or „cancer-prone personality“. We only allow ourselves to postulate this statement so strongly after having consulted the issue directly with Dr. Lydia Temoshok, the author of the term. The misinterpretation of the type C behaviour pattern led to a belief that this type of behaviour can predispose development of cancer in a person. However, according to existing research, the Type C concept describes a coping strategy that causes a faster progression of cancer and HIV due to changes in the immune system. We discuss obstacles with the Type C research and we introduce the Vignette Similarity Rating Method (VSRM), a method developed by Dr. Lydia Temoshok, enabling detection of the Type C behaviour pattern in a research., Peterková, H., Skřivanová, K., Brančíková, D., Bendová, M., Anderková, Ľ., and Literatura
Východiska: Pohybový projev zdravého organismu je charakterizován vysokou mírou variability provedení pohybového úkonu. Za situace vzniklé poruchy řízení, zejména v důsledku neurologických onemocnění, dochází v různé míře k fixnímu pohybového projevu, projevujícímu se omezením schopnosti pružné reakce na změnu zevních či vnitřních podmínek, působících v průběhu provádění cíleně zaměřené pohybové akce. Cíl: Zjistit rozdíly ve svalové aktivitě a variabilitě svalových souher akrálních a proximálních svalů během dosahu a úchopu u zdravých jedinců a u pacientů s hemiparézou. Metody: Experimentální soubor tvořilo 24 probandů po prodělané ischemické cévní mozkové příhodě (iktu) s pravostrannou hemiparézou. Kontrolní soubor tvořilo 30 zdravých probandů. Svalová aktivita byla zaznamenána pomocí povrchové elektromyografie v průběhu dosahu, úchopu a oddálení válcového a kulového předmětu. Rozdíly v hodnotách plochy pod křivkou záznamu jednotlivých svalů mezi experimentálním a kontrolním souborem byly statisticky vyhodnoceny pomocí T-testu pro nezávislé skupiny. Vztah mezi aktivitou svalů předloktí a svalů pletence ramenního byl hodnocen pomocí Spearmanova korelačního koeficientu pro neparametrické hodnoty. Výsledky: Byly zjištěny významné rozdíly v míře a počtu statisticky významných korelací akrálních a pletencových svalů. U souboru probandů s hemiparézou byla zjištěna statisticky významně nižší aktivita m. pectoralis major a naopak vyšší aktivita m. trapezius. Současně převažovala vysoká korelace m. pectoralis major a extenzorů zápěstí a prstů, na rozdíl od souboru zdravých probandů, kdy se vzájemné korelace akrálních a proximálních svalových skupin objevovaly nahodile, v menší míře a četnosti. Závěry: Výsledky ukazují na snížení variability svalové aktivity u pacientů s hemiparézou v průběhu úchopové funkce. Náhradou nedostatečné funkčnosti akrálních svalových skupin se stává relativně fixní „ko-aktivace“ s vybranými proximálními svalovými skupinami., Background: Movement of a healthy organism is characterized by a high degree of variability performance of a movement task. In a situation of a motor control lesion, mainly due to neurological disease, occurs in varying degrees to a fixed musculoskeletal manifestation. ere are manifesting in a limiting responsiveness to changing external or internal conditions during the task oriented physical action. Objective: To determine differences in muscle activity and variability between a muscle synergy of acral and proximal muscles during reach and grip in healthy subjects and stroke patients. Methods: e experimental group consisted of 24 probands aer ischemic stroke (ictus) with right-sided hemiparesis. e control group consisted of 30 healthy subjects. Muscle activity was recorded using surface electromyography during the performation of selected types of grips of cylindric and spheric objects. e differences in the area under the curve record of individual muscles between the experimental and control group were statistically evaluated using the t-test for independent groups. e relationship between the activity of the muscles of the forearm and shoulder girdle muscles was assessed using Spearman‘s correlation coefficient for non-parametric values . Results: ere were the significant differences in the size and number of statistically significant correlations distal and proximal arm muscles. In stroke group was found significantly lower activity m. pectoralis major and higher activity m. trapezius. At the same time the prevailing high correlation m. pectoralis major and extensor wrist and fingers, unlike the group of healthy subjectss, when the correlation distal and proximal muscle groups appeared at random, in a lesser extent and frequency. Conclusions: e results indicate a reduction in variability of muscle activity during grasp function of stroke patients. To compensate the lack of activity of acral muscles becomes relatively fixed „co-activation“ with selected proximal muscles., and Petra Bastlová, Ivana Barbora Frgalová, Barbora Kolářová, Milan Elfmark, Alois Krobot
A new microsporidian species of the genus Glugea Thélohan, 1891 parasitising the marine teleost fish Cephalopholis hemistiktos Rüppell, collected from the Red Sea in Saudi Arabia, is described on the basis of microscopic and molecular procedures. Spherical and whitish xenoma were observed adhering to the intestinal wall. The numerous spores contained within these xenoma, were ovoid to pyriform and measured 4.3-6.0 µm (5.1 µm) in length and 1.8-2.9 µm (2.2 µm) in width. The spore's wall was composed of two thick layers, which were thinner in the area contacting the anchoring disk. The latter appeared at the spore's anterior pole, in an eccentric position to the longitudinal axis. A lamellar polaroplast surrounded the uncoiled portion of the polar filament projected to the basal region of the spore, giving rise to 26-29 turns with winding from the base to the anterior zone of the spore. The posterior vacuole, located at the spore's posterior pole, and surrounded by the polar filament coils, was irregular and composed of light material. Molecular analysis of the rRNA genes, including the ITS region, was performed using maximum parsimony, neighbour-joining and maximum likelihood methods. The ultrastructural features observed, combined with the phylogenetic data analysed, suggest this parasite to be a new species of the genus Glugea. This is the first species of this genus to be reported from Saudi Arabia and is herein named Glugea nagelia sp. n., Abdel-Azeem S. Abdel-Baki, Saleh Al-Quraishy, Sónia Rocha, Mohamed A.

Using scanning and transmission electron microscopy, ultrastructure of the anterior organ and posterior funnel-shaped canal of Gyrocotyle urna Wagener, 1852 (Cestoda: Gyrocotylidea) from ratfish, Chimaera monstrosa (Holocephali), was studied for the first time. The proper anterior organ is localised at a short distance (about 170 µm) from an apical pore surrounded by a receptor field, whereas its distal end is marked by a muscular sphincter. The tegumental surface of this organ is covered with short filitriches of irregular length; large area of muscle layers traverse beneath the tegumental layer. The funnel-shaped canal of G. urna (2.5-3.0 mm long) is a specialised, muscular part of the posterior attachment organ; it opens on the rounded elevation on the dorsal body surface. The tegumental layer bears conical sclerite-like structures (up to 1.5 µm long). It produces electron-dense bodies that are transported into a canal lumen and surrounded thick muscle area mixed with numerous nerve fibres. The present ultrastructural study of G. urna indicates that gyrocotylideans share some ultrastructural characters of the anterior organ with spathebothriidean cestodes with a single anterior attachment sucker-like organ. In contrast, the unique posterior rosette attachment organ with funnel-shaped canal of the Gyrocotylidea resembles the haptor of polyopisthocotylean monogeneans in its position at the posterior end of the body and presumed origin. The above-mentioned features add more clarity to support the basal position of the Gyrocotylidea Poche, 1926 among cestodes. In addition, they also indicate a possible relationship of gyrocotylidean ancestors with monogeneans., Larisa G. Poddubnaya, Roman Kuchta, Glenn A. Bristow, Tomáš Scholz., and Obsahuje bibliografii
In the present paper, we describe the ultrastructure of the spermatozoon of the notocotylid Notocotylus noyeri (Joyeux, 1922) by means of transmission electron microscopy. The mature spermatozoon of N. noyeri exhibits the general pattern described in the majority of digeneans: two axonemes of the 9 + "1" pattern of the Trepaxonemata, nucleus, mitochondria, parallel cortical microtubules, spine-like bodies and ornamentation of the plasma membrane. The glycogenic nature of the electron-dense granules was evidenced applying the test of Thiéry. The ultrastructural features of the spermatozoon of N. noyeri present some differences in relation to those of the Pronocephalidea described until now, but confirm a general pattern for the Notocotylidae, namely a spermatozoon with two mitochondria and an anterior region with ornamentation of the plasma membrane associated with spine-like bodies. The posterior extremity of the spermatozoon exhibits only some microtubules after the disorganisation of the second axoneme. The present study confirms that some ultrastructural characters of the sperm cell such as the presence or absence of lateral expansions, the number of mitochondria and the morphology of both anterior and posterior spermatozoon extremities are useful for phylogenetic purposes within the Pronocephaloidea. Thus, unlike notocotylids, pronocephalids exhibit external ornamentation and a lateral expansion in the anterior spermatozoon region. Moreover, notocotylid spermatozoa present two mitochondria, whereas pronocephalid spermatozoa exhibit a single mitochondrion. Finally, pronocephalids are characterised by a type 2 posterior spermatozoon extremity, whereas notocotylids exhibit a type 3 posterior spermatozoon extremity., Papa Ibnou Ndiaye, Jordi Torres, Catarina Eira, Vladimir V.
