#1
C Liu, L G Cui, H L Wang
Ewing's sarcoma/primitive neuroectodermal tumor (EWS/PNET) in the kidney is a rare but high-grade malignant tumor that affects predominantly elder children and adolescents. Patients mostly present with nonspecific symptoms such as abdominal pain and gross hematuria. Since EWS/PNET has a rapid clinical progression with early metastasis and death, it is essential to make an accurate and early diagnosis. Once diagnosed, multimodality treatment, including radical surgery combined with adjuvant chemotherapy, and radiotherapy if necessary, is recommended...

Anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) is usually a multisystem disorder, and pulmonary renal syndrome is a common presentation. Patients with AAV are less likely to experience relapse when they progress to end-stage renal disease (ESRD). We report a rare case of diffuse alveolar hemorrhage (DAH) in relapsing AAV after eight years of haemodialysis. A 58-year-old woman was admitted to our hospital with the chief complaints of dyspnea and hemoptysis accompanied by anemia, fever, fatigue, and weight loss...

Nowadays, the regular recommended dose of decitabine for the treatment of myelodysplastic syndrome (MDS) is 20 mg/m2/day for 5 consecutive days with a relatively high incidence of treatment-related morbidities and costs. In this study, a retrospective and multicenter analysis was performed to explore the very-low-dose decitabine schedule for the treatment of patients with IPSS intermediate- or high-risk MDS. A total of 31 newly diagnosed MDS cases from 14 hospitals in Beijing received decitabine monotherapy (decitabine 6 mg/m2/day intravenously for 7 consecutive days, repeated every 4 weeks)...

The present study investigated the effects of two expired commercial medicines, like Buscopan Plus and Mesulid, commonly classified as household medical wastes, on hemocytes of mussel Mytilus galloprovincialis. Mussel hemocytes' lysosomal membrane stability (in terms of neutral red retention assay), superoxide anions (O2(·)(-)) and nitric oxides (NO, in terms of nitrites) production, lipid peroxidation (in terms of malondialdehyde/MDA content) and the formation of nuclear abnormalities (using the micronucleus/MN assay) were assessed in hemocytes of mussels treated for 7 days with appropriate amounts of each drug (the concentrations of active substances were considered in each case, due to the absence of data related with the excipients) as well as in hemocytes of post-treated/recovered mussels (7 days post-treatment/recovery period)...

BACKGROUND: During prenatal follow-up of twin pregnancies, accurate identification of birthweight and birthweight discordance is important in order to identify the high risk group and plan perinatal care. Unfortunately prenatal evaluation of birthweight discordance by 2-dimensional ultrasound (US) has been far from optimal. OBJECTIVE: To prospectively compare estimates of fetal weight based on 2-dimensional US (US-EFW) and MR imaging (MR-EFW) to actual birth weight in women carrying twin pregnancies...

Chronic HCV infection is one of the leading causes of liver-related death and in many countries it is a primary reason for having a liver transplant. HCV genotype identification has long been used in the clinical practice, since different genotypes have different response rates and required different doses and durations of IFN/RBV treatment; moreover both the frequency and the pattern of resistance to different Direct-Acting Antivirals (DAAs) classes are subtype specific. Hence the necessity to make an accurate HCV subtyping becomes a fundamental tool to optimize current and future clinical management of HCV infected subjects...

OBJECTIVE: Kaplan-Meier survival analysis may overestimate cumulative incidence in competing risks (CR) settings. The clinical significance of this overestimation has been questioned and CR methods are infrequently used. This meta-analysis compares the Kaplan-Meier method to the cumulative incidence function (CIF), a CR method. STUDY DESIGN AND SETTING: We searched MEDLINE, EMBASE, BIOSIS Previews, Web of Science (1992-2016), and article bibliographies for studies estimating cumulative incidence using the Kaplan-Meier method and CIF...

The high fat and low carbohydrate ketogenic diet (HFKD) is extensively studied within the fields of numerous diseases, including cancer and neurological disorders. Since most studies incorporate animal models, ensuring the quality of ketogenic rodent diets is important, both in the context of laboratory animal welfare as well as for the accuracy of the obtained results. In this study we implemented a modification to a commonly-used ketogenic rodent chow by replacing non-resorbable cellulose with wheat bran...

In this work we present a new PNO-based incremental scheme to calculate CCSD(T) and CCSD(T0) reaction, interaction and binding energies. We perform an extensive analysis, which shows small incremental errors similar to previous non-PNO calculations. Furthermore, slight PNO errors are obtained by using TPNO = TTNO with appropriate values of 10(-7) to 10(-8) for reactions and 10(-8) for interaction or binding energies. The combination with the efficient MP2 focal-point approach yields chemical accuracy relative to the complete basis-set (CBS) limit...

Because of the high theoretical capacity of 1675 mAh g-1 and high energy density of 2600 Wh kg-1, respectively, lithium-sulfur batteries are attracting intense interest. However, it remains an enormous challenge to realize high utilizations and loadings of sulfur in cathode for the practical applications of Li-S batteries. Herein, we design a quasi-2D Co@N-C composite with honeycomb architecture as multi-functional sulfur host via a simple sacrificial templates method. The cellular flake with large surface area and honeycomb architecture can encapsulate much more sulfur leading to high sulfur content (HSC) composites, and by stacking these HSC flakes, a high sulfur loading (HSL) electrode can be realized due to their high layer bulk density...

OBJECTIVES: Perioperative prophylaxis with cephalosporins reduces sternal wound infections (SWIs) after cardiac surgery. However, more than 50% of coagulase-negative staphylococci, an important pathogen, are cephalosporin resistant. The aim of this study was to determine the impact of adjunctive vancomycin on SWIs in high-risk patients. METHODS: We conducted a pre- and postintervention study in an academic hospital. Preintervention (2010-2011), all patients received prophylaxis with 1...

Reproductive plasticity is a key determinant of species invasiveness. However, there are a limited number of studies addressing this issue in exotic insects. The rice water weevil Lissorhoptrus oryzophilus Kuschel (Coleoptera: Curculionidae), which is native to North America, is one of the most invasive insect pests in east Asia. In this study, we investigated the reproductive status of first-generation females (progeny of overwintered weevils) from five geographic regions in southern and northern China in the field, and reproductive status and ovipositional features of females provided with suitable host plants in the laboratory after collection...
