Postpericardiotomy syndrome (PPS) can occur in up to 40% of patients after cardiac surgery. Corticosteroid therapy has long been used for pericarditis and pericardial effusion due to its anti-inflammatory proprieties. The benefit of corticosteroids for the prevention of post pericardiotomy syndrome (PPS) in not consen... |
We performed a systematic review and meta-analysis of trials assessing the efficacy of corticosteroids to prevent PPS in patients submitted to cardiac surgery. |
We searched MEDLINE, Google Scholar and the Cochrane Library databases using the key terms "corticosteroids" and "post pericardiotomy syndrome" without language or date restriction. Articles were considered for inclusion in the analysis if they comprised a population of patients submitted to cardiac surgery and a comp... |

Forecasting electricity load is an important economic problem. For an electric load forecasting task with a prediction horizon of 1–31 days ahead we decide to develop a simple model based on a system identification using the ARX model. The linear structure of the ARX model is concerned with the number of time lags of t... |

The preparation and detailed composition of an oil newly extracted from pure soy germ (not less than 96 % hypocotyle) are presented. Experiments in vivo showed that soybean‐germ oil (SGO) possesses a remarkable protective activity against UVB‐induced skin inflammation, exceeding that of tocopherol acetate by a factor o... |
Joint-like connections between clavicula and coracoid process are rarely diagnosed. In routine radiological examinations of the thorax, the authors found a posttraumatic ossification of the coracoclavicular ligament in four patients. This phenomenon can occasionally be the cause of shoulder pain. The anatomy and pathog... |

A 14-bit scientific CCD camera has been used as a medium-speed streak camera through software modifications that preserve the high dynamic range and excellent sensitivity characteristic of these cameras. Line shift speeds as short as 8.1 microsecond(s) ec are found to have no detrimental effects on image quality as lon... |
The regulation of hepatic very‐low‐density lipoprotein (VLDL) secretion is vital for lipid metabolism whose pathogenetic status is involved in fatty liver disease and dyslipidemia seen in hepatic steatosis. Accumulated evidence suggest that apolipoprotein E (ApoE) is closely related to hepatic VLDL secretion. Here, we ... |

On 23 February 1999, the Dutch Animal Health Service advised all Dutch veterinary practices to postpone vaccination against bovine herpesvirus 1 (BHV1) immediately. The day before severe disease problems were diagnosed on four dairy farms after vaccination with the same batch of BHV1 marker vaccine. Using monoclonal an... |
We develop an automated system for analyzing facial expressions using valence and arousal measurements of a car driver. This information is used by Motor Trends magazine to provide car manufacturers a report on how the drivers felt at each moment on the race track. The reason for this is that, the drivers remember only... |
We studied 41 testicular germ cell tumors (TGCT) using DNA flow cytometry and argyrophilic (silver staining) nucleolar organizer region (Ag-NOR) quantitation to evaluate the proliferative characteristics of TGCT and the significance of those analytical techniques. In nonseminomatous germ cell tumor (NSGCT), the percent... |
An edge coloring model is described for dealing with a special type of cyclic scheduling problem: each edge e of a graph has an integral weight $p_e \geqq 0$. An interval cyclic edge T-coloring is an assignment of $p_e $ cyclically consecutive colors in $\{ 1, \cdots ,T \}$ to each edge e such that no two adjacent edge... |
We present a system to detect incidents causing traffic congestion in the road network by analyzing real-time GPS data. These data are collected from tracking devices installed in the vehicles or from drivers' smartphones. After positioning the GPS coordinates on the road map, the system assigns a traffic state to each... |
By exploiting the real-valued eigendecomposition (EVD) of the centro-Hermitian matrix, a novel cyclic ESPRIT algorithm with signal selective property is presented by introducing a new forward backward smoothed covariance matrix.

The coach's actual conduct is thought to be influenced directly by his or her personal characteristics, such as age, gender, appearance, skill, and experience, as well as the demands of the situation. However, the coach's behavior set by both the organisational structure and the environment, and include factors includi... |
The attrition rate for anticancer drugs entering clinical trials is unacceptably high. For multiple myeloma (MM), we postulate that this is because of preclinical models that overemphasize the antiproliferative activity of drugs, and clinical trials performed in refractory end-stage patients. We validate the Vk*MYC tra... |

In this paper, we consider minimum bit error rate (BER) beamforming (BF) for multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems. In particular, assuming perfect channel state information (CSI) at the transmitter we optimize cyclic BF filters (C-BFFs) for minimization of the av... |

It is the purpose of the present communication to describe a family in which 2 sibs, who were products... |
A case of Pemphigus vulgaris concurrent with herpes simplex virus (HSV) infection in a 53‐yr‐old female is described, in which the diagnosis was based on oral scraping cytology. Two populations of abnormal cells were identified in the oral smear. One abnormal cell population was characterized by the presence of numerou... |
OBJECTIVE |
To analyze the expression and clinical significance of long non-coding RNA (lncRNA) actin filament-associated protein 1-antisense RNA1 (AFAP1-AS1) in oral squamous cell carcinoma (OSCC) and its effect on the biobehavior of OSCC cells. |
METHODS |
Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of lncRNA AFAP1-AS1 in the tumor tissue and matching adjacent normal tissue of OSCC patients (n=55), SCC25 cells, and normal oral keratinocyte lines (NOK) cells. The correlation between AFAP1-AS1 expression and the clinicopatho... |
RESULTS |
The expression of AFAP1-AS1 was higher in the OSCC tissues than in the NOK cells, and the relative expression of AFAP1-AS1 was higher in the SCC25 cells than in the NOK cells (P<0.001). AFAP1-AS1 expression was associated with the degree of diffe-rentiation, TNM stage, lymphatic metastasis, and poor prognosis of OSCC (... |
CONCLUSIONS |
The expression of AFAP1-AS1 was high in the OSCC tissues and SCC25 cells and is associated with the development and prognosis of OSCC. The knockdown of AFAP1-AS1 might inhibit the proliferation and invasion of OSCC cells by regulating the integrity of the actin filament.Characterization of hydrophobic interaction and a... |
Abstract The antioxidant properties of the phenothiazine nucleus (PHT) associated with mitochondrial membranes and liposomes were investigated. PHT exhibited hydrophobic interaction with lipid bilayers, as shown by the quenching of excited states of 1-palmitoyl-2[10-pyran-1-yl)]-decanoyl-sn-glycero-3-phophocholine (PPD... |
