AB  - MK-801 can mimic the cognitive, negative, psychotic, and physiological features of
schizophrenia, including increased hyperlocomotion and altered behavioral flexibility.
As N-methyl-D-aspartate (NMDA) receptor antagonist, it is widely used to test the
“glutamate hypofunction hypothesis of schizophrenia”. An extremely low-frequency
magnetic field (ELF-MF) can stimulate NMDA receptor activity, but its effect on
dysregulated glutamine transmission is unknown. Therefore, this study addresses the
effect of continuous exposure to ELF-MF (50 Hz, 0.5 mT) for 7 days on rat
psychomotor behavior induced by acute administration of MK-801 (0.25 mg/kg, i.p.).
During the experiment, adult male Wistar rats were placed near the on/off generator of
ELF-MF, injected with MK-801/saline immediately after 7-day sham/ELF-MF
exposure, and subjected to the open field test for 2 hours. Their behavior was analyzed
using the ANY-maze software and expressed as travel distance, time in movement,
and average speed while in motion in 30-min intervals. The results show that (1) acute
administration of 0.25 mg/kg MK-801 significantly increased travel distance and time
in movement from 60 to 120 min and average speed while in motion from 60 to 90
min compared with saline-injected animals; (2) 7-day exposure to ELF-MF had no
significant effect on the behavior of saline- and MK-801-injected animals compared
with the corresponding controls. Therefore, it can be concluded that this regime of
ELF-MF exposure does not affect the psychomotor behavior of rats caused by the
pharmacological modification of glutamine transmission with the applied MK-801
dose.

AB  - A review was conducted using PubMed/MEDLINE (published articles) as well as World Wide Web (video material) to determine the frequency of anterior and posterior presentation of the elephant at birth. Of 46 identified cases, 12 were in anterior and 34 in posterior presentation. The Fisher exact test (p= 0.682) did not show a statistically significant difference in the distribution of presentations between the Loxodonta africana (2 anterior and 10 posterior presentation) and Elephas maximus (10 anterior and 24 posterior presentation). The ratio between anterior and posterior presentation 6:29 (18.51% versus 81.49%) at birth without knowing dystocia, is significantly different from the distribution anterior and posterior presentation 6:3 (66.7% versus 33.3%) in cases with dystocia (Fisher exact test p = 0.012). Obtained data shows that posterior presentation at birth in elephants is more often present than anterior, while anterior presentation is more often associated with dystocia.

AB  - The carotid canal is located in the petrous part of the temporal bone and transmits the internal carotid artery along with the venous and sympathetic nerve plexus. The shape, location and dimensions of the carotid canal are clinically very important especially in cases of skull base surgery. The aim of this study was to investigate the morphological and morphometric parameters of the external aperture of the carotid canal in Serbian population. The study included 24 dry adult skulls and 36 dry adult temporal bones. Diameters and distances of the external aperture of the carotid canal from various important landmarks of the skull base were measured. The shape of the external carotid canal aperture was also noted. Digital data were processed in the ImageJ software. The average length of the external aperture of the carotid canal in all investigated specimens (skulls and temporal bones) on the right and left sides was 7.31±1.01 mm and 7.71±1.06 mm, respectively. The average width of the external aperture of the carotid canal on the right side was 5.82±0.78 mm while on the left side was 6.20±1.04 mm. The frequency of different shapes of the external aperture of the carotid canal was as follows: round in 45 (53.57 %), oval in 25 (29.76 %), and the rarest was almond shape noted in 13 (15.47 %) cases. There were no statistically significant differences in all measured parameters between genders and body sides. The only statistical significance was found in females between right and left side in relation with length (AP diameter) of the external aperture of the carotid canal. The results of this study will be useful for neurosurgeons to improve different surgical approaches to the petrous part of the internal carotid artery and prevent its complications.
AB  - El conducto carotídeo se encuentra en la parte petrosa del hueso temporal y da paso a la arteria carótida interna junto con el plexo nervioso venoso y simpático. La forma, ubicación y dimensiones del canal carotídeo son clínicamente muy importantes, especialmente en casos de cirugía de la base del cráneo. El objetivo de este estudio fue investigar los parámetros morfológicos y morfométricos de la apertura externa del canal carotídeo en la población serbia. El estudio incluyó 24 cráneos adultoss y 36 huesos temporales adultos secos. Se midieron los diámetros y distancias de la apertura externa desde varios puntos de referencia de la base del cráneo. También se observó la forma de la apertura del canal carotídeo externo. Los datos digitales se procesaron con Software ImageJ. La longitud promedio de la apertura en todos los especímenes investigados (cráneos y huesos temporales) en los lados derecho e izquierdo fue de 7,31 ± 1,01 mm y 7,71 ± 1,06 mm, respectivamente. El ancho promedio de la apertura en el lado derecho fue de 5,82 ± 0,78 mm mientras que en el lado izquierdo fue de 6,20 ± 1,04 mm. La frecuencia de las diferentes formas de la abertura externa fue la siguiente: redonda en 45 (53,57 %), ovalada en 25 (29,76 %), y la más rara fue la forma de almendra observada en 13 (15,47 %) casos. No hubo diferencias estadísticamente significativas en todos los parámetros medidos entre sexos y lados del cuerpo. La única estadística significativa se encontró en las mujeres entre el lado derecho e izquierdo en relación con la longitud (diámetro AP) de la apertura externa del conducto carotídeo. Los resultados de este estudio serán útiles para un mejor enfoque quirúrgico de los neurocirujanos en la parte petrosa de la arteria carótida interna, y advertir posibles complicaciones.
