The purpose of this study was to determine the possible morphometrical differences of the corpus callosum between professional musicians and non-musicians. Certain callosal dimensions and areas were measured in 20 professional musicians and compared with 20 age-, sex- and handedness-matched control group by using in vivo magnetic resonance imaging (MRI). Sagittal T1-weighted midsagittal section...

Morphology of the nematode Viguiera dicrurusi Gupta, 1960 harboured by Dicrurus macrocercus albirictus (Hodgson) (Passseriformes: Dicruridae) from Baruipara in 24-Pargonas (South) district, West Bengal, India was studied by light and scanning electron microscopy (SEM). This represents the first study of V. dicrurusi using SEM. Scanning electron micrographs provided detailed information about th...

In the medieval necropolis of Vicenne (Italy) among 130 skeletons, thirteen horsemen, recognized on the basis of the contextual burials with horse, have been found. This rite, rarely found in Europe, recalls an Asian rite, attested from the Iron Age to the Age of Migration in nomadic Asian populations. Local and Germanic goods were also found. In order to study the anthropological composition o...

Intestinal explants are a useful model for toxicological and pathological studies, but the maintenance of tissue viability for longer periods of incubation remains challenging. The aim of this study was to evaluate the effect of age on the viability of intestinal explants. Jejunal explants were obtained from 24and 42-day-old piglets. The explants were incubated for two or four hours and were th...

background: endometrial development has an important role in blastocyst adhesion and implantation. during ivf cycles, endometrial development is enhanced by progesterone. objective: the aim of this study was to compare ultrastructural and morphometrical characteristics of mice uterine endometrium in natural cycle with those in superovulated cycles received progesterone or sildenafil. materials ...

Tabanus pseudonebulosus, new species, is described based on 217 female specimens and 5 males collected in Venezuela (Guarico, Aguaio, Santa Elena, and Palmarito) and in Brazil (Parcí: Santana do Araguaia, Serra das Andorinhas in São Geraldo do Araguaia, Serra Norte Carajás and Gorotire; Amazonas: Canutama; Mato Grosso do Sul: Corumbá), mostly in open vegetation, scrub forest and in rocky enviro...

Morphometrical data of pronotum, elytra, and total length of adult males and females of a Gratiana spadicea population from southern Uruguay are given. Descriptions and illustrations of aedeagus and spermatheca are provided for the first time. Females were significatively larger than males in total length. The coefficient of variation of the aedeagus measures ranged from 3.7% to 7.7%, and those...
