Radial artery variations are of importance for clinicians, whether in angiographic examinations or surgical approaches. The high origin radial artery is the most frequent arterial variation observed in the upper limb, showing an incidence of 14.27% in dissection material and 9.75% in angiographic examination. In the present study an unusual course of the radial artery and its relation with the median nerve has been evaluated. During embryological development the radial artery sprouts from two arterial buds arising from the lateral side of the brachial artery and coalescing with each other. The artery lies in the forearm and is overlapped by the brachioradial muscle. In this particular case the radial artery originated from the medial side of the brachial artery and crossed the median nerve twice in an unusual manner 8 cm below the point at which the deep brachial artery arose and 12 cm above the intercondylar line. These results will enhance anatomical knowledge of the region and reduce complication in surgical approaches.
The aim of this article is to review current reports pertaining the effects of treating patients with diagnosed degenerative disc disease in the lumbosacral section of the spine. Materials and methods: the method of descriptive analysis was used. The research was conducted on the basis of materials from MEDLINE and EMBASE databases from the last ten years. The cases of patients with sciatic neuritis caused by degenerative disc disease undergoing conservative treatment, and similar group of patients treated surgically, were analysed. Conclusions: Conservative treatment lowers the intensity of pain, but does not improve the functional abilities of the spine. Surgical treatment gives good and quick therapeutic results, but its long-term effects do not seem better than in the case of conservative treatment. Moreover, surgical treatment may result in serious complications. In rare cases the condition results in a severe impairment of motor functions in legs and sphincter paralysis. Such patients should undergo immediate surgical treatment.
 The sarcoplasmic reticulum Ca2+-ATPase (SERCA) isoforms are normally expressed in coordination with the corresponding myosin heavy chain (MyHC) isoforms in the fibers of skeletal muscle but this coordination is often disrupted in pathological conditions. In the streptozotocin-induced diabetes of rats (stz-rats), the soleus muscle showed peripheral neuropathy and the SERCA2a level decreased in type I (slow-oxidative) fibers compared to the control muscles, whereas the expression of the corresponding slow MyHC1 did not change. No difference was found at the mRNA and protein levels of SERCA and MyHC isoforms in the whole soleus, except that the level of the SERCA2a protein specifically declined in stz-rats compared to the controls. This shows that the coordinated expression of SERCA2a and MyHC1 is disrupted at the SERCA2a protein level in the diabetic soleus. The results are in line with previous observations that regulators of the Ca-homeostasis may adapt faster to type I diabetes than the contractile elements.
