Abstract
PURPOSE The aim of this study was to show the different origins and courses of the extracranial VA on CTA with special emphasis on embryological considerations. The duplicated VA is an anomaly that has been assumed to predispose for dissection and to be associated with aneurysms. We report its frequency and clinical significance. METHODS We retrospectively reviewed CTA of 539 patients by using a contrast-enhanced CTA protocol of the VA on CT. RESULTS Ninety-four-point-two percent of left VA originated from left subclavian artery and entered the transverse foramen at C6 in nearly all cases. Six-point-three-percent of left VA (m = 4 %, f = 10 %) originated from the aortic arch and entered the transverse foramen either at C4, C5 or C7 but never at C6. One case of an aberrant retroesophageal right VA originated from the aortic arch distal to the left subclavian artery and entered at C7 (0.19 %). All other right VA originated from the right subclavian artery (99.8 %) and entered between C4 and C6. We diagnosed four cases of duplicated VA (0.74 %) with a female predominance (1.9 %) without any signs of dissection on CTA. Two cases with VA duplication had intracranial arterial aneurysms. CONCLUSIONS The VA is a longitudinal anastomosis of segmental metameric arteries. The level of entrance into the transverse foramen indicates which metameric artery or arteries persist. Duplication corresponds to persistence of two segmental arteries and is a rare phenomenon. VA duplication might be associated with vascular lesions.

Abstract
BACKGROUND GB virus C (GBV-C) infection is transmitted by blood exposure and associated with lower human immunodeficiency virus (HIV) load and slower HIV disease progression. Few studies describe predictors of acute GBV-C infection following transfusion in HIV-infected patients. METHODS We used a limited-access database from the National Heart Lung and Blood Institute's Viral Activation Transfusion Study, a randomized controlled trial of leukoreduced versus nonleukoreduced transfusions received by HIV-infected, transfusion-naive patients. Blood samples from 489 subjects were tested for GBV-C markers in pretransfusion and posttransfusion samples. We estimated the risk of acquiring GBV-C RNA and predictors of GBV-C acquisition, using pooled logistic regression. RESULTS GBV-C RNA was detected ≤120 days following the first transfusion in 22 (7.5%) of 294 subjects who were GBV-C negative before transfusion. The risk of GBV-C RNA acquisition increased with each unit transfused (odds ratio, 1.09; 95% confidence interval, 1.06-1.11). Lower baseline HIV load and use of antiretroviral therapy were associated with subsequent GBV-C RNA acquisition, after control for units of blood transfused. Leukoreduced status of transfused units was not associated with GBV-C transmission. CONCLUSIONS Blood transfusion is associated with a significant risk of GBV-C acquisition among HIV-infected patients. Transmission of GBV-C by blood transfusion was inversely related to HIV load.

Abstract
Ancient autophagy pathways are emerging as key defense modules in host eukaryotic cells against microbial pathogens. Apart from actively eliminating intracellular intruders, autophagy is also responsible for cell survival, for example by reducing the deleterious effects of endoplasmic reticulum stress. At the same time, autophagy can contribute to cellular suicide. The concurrent engagement of autophagy in these processes during infection may sometimes mask its contribution to differing pro-survival and pro-death decisions. The importance of autophagy in innate immunity in mammals is well documented, but how autophagy contributes to plant innate immunity and cell death is not that clear. A few research reports have appeared recently to shed light on the roles of autophagy in plant-pathogen interactions and in disease-associated host cell death. We present a first attempt to reconcile the results of this research.

Abstract
AIM This review comments on epidemiology, diagnosis and general principles of surgical management in patients with acute abdomen. DEFINITION AND EPIDEMIOLOGY: The most common cause of acute abdominal pain is non-specific abdominal pain (24 - 44.3 % of the study populations), followed by acute appendicitis (15.9 - 28.1 %), acute biliary disease (2.9 - 9.7 %) and bowel obstruction or diverticulitits in elderly patients. Acute appendicitis represents the cause of surgical intervention in two-thirds of the children with acute abdomen. DIAGNOSIS A standardised physical examination combined with ultrasonography (US) represents the initial investigation in patients with acute abdominal pain. Due to the risk associated with radiation and due to the costs, a selective use of CT imaging is recommended. The work-flow given in this paper restricts the use of CT imaging to less than 50 % of patients with acute abdominal pain. Diagnostic laparoscopy should be considered in patients without a specific diagnosis after appropriate imaging and as an alternative to active clinical observation which is the current practice in patients with non-specific abdominal pain. MANAGEMENT Acute small bowel obstruction has previously been considered as a relative contraindication for laparoscopic management, but it has been shown in the meantime that laparoscopic treatment is an elegant tool for the management of simple band small bowel obstruction. Bedside diagnostic laparoscopy is recommended in intensive care unit (ICU) patients with acute abdomen or sepsis of unknown origin, in suspicion of acute cholecystitis, diffuse gut hypoperfusion and mesenteric ischaemia or in refractory lactic acidosis, especially after cardiac surgery. Early administration of analgesia to patients with acute abdominal pain in the emergency department will reduce the patient's discomfort without impairing clinically important diagnostic accuracy and is recommended on the basis of some prospective randomised trials. However, the impact on diagnostic accuracy depends on dosage, kind of application and cause of acute abdominal pain. A practice of judicious provision of analgesia therefore appears safe. There are significant differences between the knowledge of the current literature and the routine practice of providing analgesia as a survey has shown demonstrating that less than 50 % of paediatric emergency physicians and paediatric surgeons are usually willing to provide analgesia before definitive diagnosis.

Abstract
OBJECTIVE Low density lipoprotein cholesterol (LDL-C) is an independent and modifiable risk factor for development of cardiovascular disease (CVD). Postprandial lipid metabolism has been linked to CVD, but little is known about the postprandial LDL-C profile in patients with type-2 diabetes (T2DM). We aimed to study the postprandial levels of LDL-C in T2DM patients. MATERIAL AND METHODS After an overnight fast, 74 T2DM patients, mean age approximately 60 years, were served a standard fat-rich meal of 3515 kJ containing 54% fat, 13 % protein and 33 % carbohydrates. Only drinking water was allowed postprandially. Blood samples were drawn at times 0 (fasting), 1.5, 3.0, 4.5 and 6.0 h (postprandial). In all samples, LDL-C was measured with modified beta quantification (separation by ultracentrifugation followed by measurement of infranate high density lipoprotein cholesterol (HLD-C) using a homogeneous assay). RESULTS At all postprandial times, levels of LDL-C showed highly significant (p < 0.005) decreases compared to time 0 (mean [95% CI] maximum change in LDL-C levels at 3.0 h: -0.16 mmol/L [-0.12; -0.20]; p < 0.001). Independently of fasting LDL-C levels and ongoing statin therapy, LDL-C decreased significantly more in female compared to male patients postprandially (mean [95% CI] maximum unadjusted change versus time 0 in LDL-C for men [n=56] at 3.0 h: -0.14 mmol/L [-0.19; -0.10], p < 0.001; for women [n=18] at 4.5 h: -0.26 mmol/L [-0.35; -0.18], p < 0.001; -0.14 mmol/L [-0.24; -0.05], p = 0.005 between genders for the mean [95% CI] fasting adjusted difference at 4.5 h in the change versus time 0 in LDL-C; gender by time interaction: p = 0.007 (repeated measures mixed model)). CONCLUSIONS In T2DM patients served a fat-rich meal, levels of LDL-C decreased significantly more in women compared to men postprandially, irrespective of fasting levels or ongoing statin therapy. This might have implications in the atherosclerotic process and on any difference in the risk of CVD between genders.

Abstract
HISTORY AND CLINICAL FINDINGS The histological investigation of a surgical specimen (after cholecystectomy) from a 73-year-old woman revealed a poorly differentiated carcinoma with glandular structures and a lymph node metastasis. INVESTIGATIONS Comparative immunochemistry, done to exclude metastatic growth of the previously demonstrated endometrioid ovarian carcinoma, was (1) negative for CK7 and CA125, positive for CK20, chromogranin A and synaptophysin (gall bladder and lymph node metastasis); (2) positive for CK7 and CA125, negative for CK20, chromogranin A and synaptophysin (ovary). DIAGNOSIS The tumor lesion within the gall bladder and lymph node was classified as a neuroendocrine carcinoma, not a metastasis of the ovarian carcinoma. TREATMENT AND CLINICAL COURSE The patient underwent another laparotomy with resection of the stump of the cystic duct and the liver parenchyma surrounding the former gall bladder, including dissection of the lymph nodes within the hepatoduodenal ligament. After 14 months another metastasis of the neuroendocrine carcinoma of the gall bladder was found. But for eight years there has been no recurrence of the endometrioid adenocarcinoma of the left ovary. CONCLUSION Because of the increasing incidence of malignant diseases and second neoplasms there is a growing need for such diagnostic tests as histological and immunohistochemical analysis. This is the first case, according to the available literature, of an endometrioid adenocarcinoma of the ovary concomitant with a neuroendocrine carcinoma of the gall bladder.

Abstract
We report direct laser spectroscopy of the 1S0-3P0 transition at 265.6 nm in fermionic isotopes of neutral mercury in a magneto-optical trap. Measurements of the frequency against the LNE-SYRTE primary reference using an optical frequency comb yield 1 128 575 290 808.4+/-5.6 kHz in 199Hg and 1 128 569 561 139.6+/-5.3 kHz in 201Hg. The uncertainty, allowed by the observation of the Doppler-free recoil doublet, is 4 orders of magnitude lower than previous indirect determinations. Mercury is a promising candidate for future optical lattice clocks due to its low sensitivity to blackbody radiation.
