The styloid process (SP) is a slender cylindrical bony projection of the temporal bone with two ligaments and three muscles attached to it. Symptomatic SP elongation is also referred to, as Eagle's Syndrome. The aim of the present study is to investigate the distribution of the SP length in a young adult Greek population. Moreover we provide a comparison of the results by using two different methods for assessing SP elongation, as described in the literature. Finally we explore the possibility of using OPGs, as a diagnostic aid by investigating inter-examiner, intra-examiner and inter-examination variability and we propose a limit for SP elongation measurable in orthopantomograms (OPGs)...

Neural and vascular variations in the axilla and upper limb area are usually paired, but coexistence of muscular aberration on top of this is uncommon. The current case report emphasizes on the unilateral coexistence of a three-headed (tricipital) biceps brachii muscle, a two-headed coracobrachialis with an accessory muscle bundle joining the superficial and deep heads of coracobrachialis muscle. On the ipsilateral side of the 72-year old male cadaver, a connecting branch originated from the musculocutaneous nerve and joined the median nerve after surpassing the accessory muscle bundle...

Variations of the renal veins are well described in the literature, although variations concerning the ureter are considered a rare finding in cats. The circumcaval ureter is one of the rarest variations of the ureter and is characterized by a loop of the ureter posterior to the caudal vena cava, as such, this variant is also known as preureteral vena cava and retrocaval ureter. It is thought to be caused by a deviation during embryonic development of the aforementioned vein. Due to its rarity, there are scarce reports of the circumcaval ureter in cats, and its association with two renal veins makes it less common as well...

A replaced right hepatic artery (rRHA) arising from the superior mesenteric artery and an interlobar parenchymal bridge over the sagittal fissure have been observed on a 64-year-old formalin-fixed male cadaver in the anatomy laboratory. As we have followed a detailed segmental anatomy, we encountered an arterial distribution of segment IV featuring a different pattern from the literature so far. According to our observations, the segment I is supplied by both left (LHA) and middle (MHA) hepatic arteries; the segments II and III are supplied by the LHA while the segment IV is supplied by both the MHA and rRHA...

Evaluation of semiserial sections of 14 normal hearts from human fetuses of gestational age 25-33 weeks showed that all of these hearts contained thin veins draining directly into the atria (maximum, 10 veins per heart). Of the 75 veins in these 14 hearts, 55 emptied into the right atrium and 20 into the left atrium. These veins were not accompanied by nerves, in contrast to tributaries of the great cardiac vein, and were negative for both smooth muscle actin (SMA) and CD34. However, the epithelium and venous wall of the anterior cardiac vein, the thickest of the direct draining veins, were strongly positive for SMA and CD34, respectively...

The optic nerve (ON), a major component of the visual system, is divided into four segments: the intrabulbar (IB), the intraorbital (IO), the intracanalicular (ICn) and the intracranial (ICr). The ICr ends with the two nerves partially decussating in the optic chiasm (OCh). The purpose of this study is to provide a detailed description of the dimensions of the OC (the diameter and the surface area of its foramina and the central segment, as well as the length of the OC and the thickness of its walls) as well as the ON (the length of the ON segments, the diameter of the ICn segment of the ON, the angle of decussation in the OCh, as well as the distance between the two ON at the cranial foramen of the OC)...

Neuroinflammation has a definitive role in neurodegenerative diseases, such as Parkinson's and Alzheimer's disease. In addition to its pathogenic ligands, toll-like receptors (TLRs) can be activated by damaged endogenous molecules that induce inflammatory signalling pathways such as high-mobility group box 1 protein (HMGB1). Using an ex-vivo rat optic nerve (RON) model, we sought to determine the effects of lipopolysaccharides (LPS; TLR4 agonist), zymosan (TLR2 agonist) or HMGB1-with or without TLR2/4 antagonists, on the expression of glial fibrillary acidic protein (GFAP) and nuclear factor kappa B (NF-ҡβ) for signalling pathway and astrocyte reactivity, using double immunohistochemistry; as well as on the modulation of the neurotoxicity...
