Spine is a column that consists of consecutively lined up vertebras. It includes medulla spinalis. It contributes the motions of head, neck and body. Spine is not a straight column. It figures a convexity towards the front of the spine (lordosis) at cervical and lumbal areas in adults. It also figures a convexity towards the back of the spine (kyfosis) at thoracic and sacral spine area. In this study, lateral MRI images of 731 children between 1-16 years old were examined and their cervical lordosis, thoracic kyfosis and lumbal lordosis angles were measured with Cobb method using ImageJ program for every age group...

Modern joint arthroplasties rely on osseointegration of metal components through bone ingrowth into hydroxyapatite (HA) layers. However, such surfaces are prone to colonisation by bacteria and formation of biofilms. Application of silver nanoparticles (SN) to hydroxyapatite coatings could reduce the risk of infection, however little is known about how this would affect the process of bone ingrowth. This study examined osseointegration of conventional and SN doped HA coatings in a rabbit model. In this study, twelve cylindrical implants coated with conventional and SN doped HA were implanted into New Zealand white rabbit femora, with each animal receiving both types of implants...

The ancient Greek physicians skipped the description of thyroid gland probably due to their difficultly to understand the anatomy and the existence of this organ. Although the ancient physicians had described the disease bronchocele (Greek: Βρογχοκήλη), this disease did not correspond exactly to goiter. The first official description of this gland was made by Andreas Vesalius (1514-1564). Thomas Wharton (1614-1673) in his work Adenographia was the one who coined the term Glandulae thyreoidea.

BACKGROUND: The western-style diet is characterized by the high intake of energy-dense foods. Consumption of either high fructose diet or saturated fat resulted in the development of metabolic syndrome. Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of the metabolic syndrome. Many researchers studied the effect of high-fat diet (HFD), high fructose diet (HFruD) and high fructose high-fat diet (HFHF) on the liver. The missing data are the comparison effect of these groups i...

Despite the fact that numerous reptile species are widely studied by the researchers, information describing the detailed structure of particular organs in many reptiles is missing. The tongue of the sand lizard (Lacerta agilis) was examined under the light and scanning electron microscope. It is divided into bifurcated apex, corpus and bifurcated radix. The tip of the lingual apex is devoid of lingual papillae. The remaining dorsal surface of the tongue bears either fused papillae in the form of caudally directed ridges or individual papillae represented by mushroom like or semilunar prominences (lingual apex) or fish scale-like papillae (lingual corpus) and horizontally laid ridges extending in the form of lobulated prominences (lingual corpus, lingual radix)...

Although anatomical variations in the upper limb are frequent, coexistence of multiple combined variations is rare. During a routine educational dissection at Jeju National University Medical School, three muscular variations were found in a 75-year-old Korean male cadaver, in which a supraclavicular cephalic vein was also found in ipsilateral upper extremity during skinning (Go et al., 2017). Here we describe characteristics of the pectoralis quartus muscle, the supernumerary head of biceps brachii muscle and an accessory head of flexor digitorum profundus muscle, and discuss their coexistence from morphological and embryological points of view...

The lateral nasal wall contains the nasal turbinates (conchæ) which are used as landmarks during functional endoscopic surgery. Various morphological possibilities of turbinates were reported, such as bifidity of the inferior turbinate, and extra middle turbinates, such as the secondary middle turbinate. During a retrospective Cone Beam Computed Tomography study of nasal turbinates in a patient we found previously unreported variants of the superior nasal turbinates. These had, bilaterally, ethmoidal and sphenoidal insertions...

We describe the arterial supply of a human kidney harvested post-mortem from a 75-year-old female volunteer body donor. The kidney was analysed with contrast-enhanced computed tomography, and corrosion casting was used to reveal the kidney's angio-architecture. In the left kidney, we observed four renal arteries, each originating directly from the abdominal aorta. Three renal arteries, including the main renal artery, coursed through the renal hilum, and the fourth renal artery reached the lower kidney pole...
