871 mesenteric lymph nodes taken from 110 native cattle from Urmia slaughter-house with differentages were examined for Linguatula serrata infection. The lymph nodes were studied based on their colourand consistency. 44% of the cattle were found positive for L. serrata infection. The number of parasitesisolated from each infected lymph node varied from 1 to 69 with a mean of 5.48. There were no...

Histological examinations of the intracerebral and retinal arteries were preformed in patients who had cerebrovascular disease and in those cases who did nott. Fibrinoid degeneration, fibrous nodule, and splitting, which are most frequently found in putamen, thalamus and pons, are thought to be the main changes in cerebral hemorrhage and infarction. Fibrous and fibro-hyalinoid thickenings of th...

Mitochondrial DNA (mtDNA) restriction-site maps for six species (10 strains) of the Drosophila montium subgroup were established. A total of 50 restriction sites were mapped, corresponding to 1.67% of the mtDNA genome. On the basis of differences in the restriction sites, nucleotide divergence (delta) was calculated for each pair of species (strains), and phylogenetic trees were constructed by ...

To find out the wood species used in national structures late Joseon Dynasty, 11 volumes of Yeonggeon-Uigwes were reviewed. It was confirmed that mainly for repair and restoration palaces, shrines, fortresses. In 17th to 20th centuries, specified have revealed either hardwood or softwood. As species, Juglans mandshurica, Zelkova serrata, Fraxinus rhynchophylla, Betula schmidtii, Paulownia corea...

linguatula serrata (l. serrata), an aberrant arthropod of the pentastomida phylum, inhabits the canine respiratory system as its final host. intermediate hosts include humans and herbivores. humans can be infected via consumption of raw or under-cooked liver or lymph nodes of sheep, goats, and cattle. a few human cases have been reported from iran. here, we have reported a case of pentastomiasi...

objective it has previously been shown that prenatal maternal administration of boswellia serrata gum resin (frankincense) improved learning and memory performance associated with an increase in the size of neuronal bodies in ca3 (cornu ammonis) of hippocampus. continuing the previous work, a morphometric study was designed on ca3 field to examine precisely the effect of prenatal administration...

background:  linguatulosis is a rare zoonotic parasitic infection, in which human plays the role of both defini­tive and intermediate host and can be occasionally infected. this study determines the status of infection in live­stock and its po­tential risk to men in the northwestern province of azarbaijan-e-sharghi, iran. methods: in a cross-sectional study from june 2007 to june 2008, 800 slau...

Linguatula serrata, a cosmopolitan parasite, is commonly known as tongue worm belonging to the subclass Pentastomida.We collected the nymphal stage of the worm from mesenteric lymph nodes of cattle and identified these as L. serrata based on morphology and morphometry. The 18S rDNA sequences showed no intraspecific variation, although cox1 sequences showed 99.7-99.9% homology. In the phylogenie...

The brown alga Dictyopteris serrata (Areschoug) Hoyt (Dictyotales, Phaeophyceae) is reported from the coast of western Australia, representing the first reliable record of this species from outside the south-western Indian Ocean. Distinguishing features of D. serrata are: a broad thallus with marginal teeth, veins extending from the midrib obliquely towards the blade margin, and embedded tetras...

With the help of scanning electron microscopy, high resolution X-ray tomography (µCT), and finite element analysis, the mechanical and functional properties of the mandibles and associated muscles of the beetle Priacma serrata (LeConte) (Coleoptera: Archostemata) were studied. The combination of these techniques allowed for studying mechanical properties of the headmandible- system without usin...
