In the present study, we described ultrastructural changes occurring in the  neurons of the hypothalamic arcuate nucleus after food deprivation. Young  male Wistar rats (5 months old, n = 12) were divided into three groups. The  animals in Group I were used as control (normally fed), and the rats in Groups  II and III were fasted for 48 hours and 96 hours, respectively. In  both treated  groups, fasting caused rearrangement of the rough endoplasmic reticulum forming  lamellar bodies and membranous whorls...

The aim of this study was to investigate the influence of two periods of life,  namely P28 and P360, on the changes in interleukin-1beta (IL-1b) immunoreactivity  (-ir) in the hippocampus (CA1, CA3, DG) and amygdala (central-CeA,   medial-MeA) caused by acute and repeated open field (OF), or by forced swim  (FS) exposition...

hanges in NGF release during stressful events have been associated with the  activation of neurons expressing NGF  receptors. This study examined the influence  of acute stress-induced stimulation on NGF/c-Fos colocalization in the  following limbic regions: the paraventricular (PV) nucleus of the hypothalamus, medial (MeA) nucleus of the amygdala, and CA3 hippocampus....

Neuronavigation is a kind of image-guided surgery used during neurosurgical  procedures. Based on specific equipment which is compatible with the software  calculating and processing the patient’s data; this method allows the determination  of the location of anatomical structures and visualisation of surgical instruments  in the operative field...

Proper recognition of the particular structures that form the triangle of Calot is  essential for the proper and safe performance of laparoscopic cholecystectomy.  Proper recognition, ligation, and cut of the cystic duct and cystic artery  with branches (dorsal and ventral) remain an integral condition for the removal  of the gallbladder. Calot’s triangle, as an orientation structure, determines the  most common location of the cystic artery....
