BACKGROUND Osteonecrosis of the humeral head is a frequent complication in adults with sickle cell disease. However, little is known about the rate of, and the factors influencing, progression of symptomatic shoulder osteonecrosis in patients with this disease. METHODS Eighty-two adult patients with sickle cell disease and symptomatic osteonecrosis of the humeral head (104 shoulders) were ide...

The expression of intron-containing messages has been shown to occur in a variety of diseases including lactic acidosis, Cowden Syndrome, and several cancers. However, it is unknown whether these intron-containing messages result in protein production in vivo. Indeed, intron-containing RNAs are typically retained in the nucleus, targeted for degradation, or are repressed translationally. Here, ...

background and objectives: study of deleterious effect of neurotoxins on the animals' brain is a fascinating research plan. in this project, the damage effect of colchicine on the hippocampal cornu ammonis 1 (ca1) was examined by the studying the hippocampal tissue. materials and methods: injections of colchicine (1-75 μg/rat, intra- hippocampal ca1) were performed in cannulated male wistar rat...

the role of the ventromedial nuclei of the hypothalamus (vmn) in food behavior was studied in adult male rats, allocated in 3 groups: control, sham and lesioned. electrolytic lesions were induced stereotaxically (1.2 ma, 15 sec). results revealed a significant decrease (p

coincidental occurrence of hepatocellular carcinoma (hcc) and cholangiocarcinoma, known as “collision tumors”, within a cirrhotic liver is rare. herein, we report a case of liver transplantation (lt) in a patient with such collision tumors. our patient was a 56-year-old woman with hepatitis c virus-related cirrhosis and 2 focal hepatic lesions, measuring 1.5 and 3 cm, in the liver segments 8 an...

introduction: an important consideration in endodontic treatment is the elimination of microorganisms, including fungi, from the complex three- dimensional root canal system. candida albicans (ca) has a major role in endodontic treatment failure as the most important fungus isolated from the root canal system. the present study was carried out to evaluate the presence of ca in the teeth requiri...

Nerve sheath myxoma (NSM) is a benign peripheral nerve sheath tumor that rarely occurs in the oral cavity. Among the 23 reported intraoral cases, no lesion has previously been reported on the gingiva. In this report, we describe the first gingival case of oral neurothekeoma with histopathologic and immunohistochemical characteristics. The patient, a 32 year old female presented with a slowly gr...

Abstract Background Correct identification of the culprit lesion in NSTEMI is essential, particular for patients whom a culprit-only strategy attractive (e.g., elderly and frail patients). However, when identifying NSTEMI, angiography can be ambiguous correct therefore challenging based on angiography, ECG- echocardiographic changes alone (standard-of-care). In fact, this challenge remains unre...

Efferent auditory pathways have been implicated in sound localization and its plasticity. We examined the role of the olivocochlear system (OC) in horizontal sound localization by the ferret and in localization learning following unilateral earplugging. Under anesthesia, adult ferrets underwent olivocochlear bundle section at the floor of the fourth ventricle, either at the midline or laterally...

There was made the analysis of wound ballistics modern expansive bullets in comparison with shell on 25 blocks ballistic plasticine (ROMA PLASTILINA No. 1, Ballistic Testing Backing Material), USA, which one shot from an AKS-74 automatic firearm and carbine ZBROYAR Z-10 optical sight fired. The bullet speed highest 5.45x39 caliber cartridge a V-max bullet. – 1185 m/s, low .308 Win SP, 664 m/s. ...
