BACKGROUND The geographic distribution of osteochondroma (OC) varies greatly around the world. There has been no recent report on OC in a large Chinese population. The aim of this study was to characterize OC by an epidemiological analysis of the clinical data from one medical institution in South China. METHODS We searched medical electronic records from January 2001 to January 2016 in one l...

A major fraction of fine particle matter consists of organic carbon (OC) but its origin is still inadequately known. In this study the sources of OC were investigated in the northern European urban environment in Helsinki, Finland. Measurements were carried out over one year and they included both filter (PM 1) and online methods. From 5 the filter samples OC, elemental carbon (EC), water-solub...

BACKGROUND Oncocytic carcinoma (OC) arising in the submandibular gland is an unusual malignant neoplasm, with <20 cases previously reported. The cancer is characterized by numerous morphologically abnormal mitochondria present in the cytoplasm and marked cellular pleomorphism. At its most severe, the tumor may invade into the surrounding tissues, including intravascular, lymphatic, or perineura...

Nowadays the laparoscopic approach represents the gold standard for acute cholecystitis, but we are facing little evidence regarding the elderly patients. The purpose of this study is to define the benefits in terms of early outcome for laparoscopic cholecystectomy in patients over 70 years old and to compare them with the open cholecystectomy through a retrospective study of patients that unde...

BACKGROUND Treatment outcomes appear to be better for ovarian cancer (OC) patients carrying the BRCA1/2 germline mutation than for patients with sporadic OC. However, most published data are for North American, British and Jewish populations. There have been very few studies on treatment outcomes in Central and Eastern European patients with OC. The aim of this study was to analyse prognostic f...

The effect of cropping system on the distribution of organic carbon (OC) and nitrogen (N) in soil aggregates has not been well addressed, which is important for understanding the sequestration of OC and N in agricultural soils. We analyzed the distribution of OC and N associated with soil aggregates in three unfertilized cropping systems in a 27-year field experiment: continuously cropped alfal...

BACKGROUND The superiority of several immunochemical fecal occult blood tests (I-FOBT) over guaiac-based tests in colorectal cancer screening is now established. The aim of this study was to compare the analytical performance of 3 quantitative I-FOBTs. METHODS Stool samples from 10 healthy volunteers, initially I-FOBT negative, supplemented with human blood, were used to compare reproducibili...

A study was conducted to appraise the effect of different stocking densities on three male morphotypes named blue claw (BC), orange claw (OC) and small male (SM) at harvest&nbsp; in all-male culture and to assess the growth performance of&nbsp; BC, OC and SM in each isolated culture. Trials involving three stocking densities of all-male prawn viz., 20, 30 and 40 juvenile m-2 were carried out in...

OBJECTIVE To compare the efficacy of multidose medroxyprogesterone acetate and a multidose monophasic combined oral contraceptive (OC) for hemodynamically stable women with nongestational, acute uterine bleeding. METHODS Hemodynamically stable patients with acute uterine bleeding sufficient to justify immediate medical or surgical intervention were enrolled in an open-label, randomized trial ...

Third generation oral contraceptives (OC), containing the progestins desogestrel and gestodene, were introduced in the 1980s in a attempt to lower the risk of cardiovascular side effects. However, the observation that desogestrel and gestodene in combined OC were related to a 50 to 100% greater risk of venous thromboembolism (VTE) suggested that the issue is more complex than originally thought...
