Property preserving encryption (PPE) can enable database systems to process queries over encrypted data. While a lot of research in this area focusses on doing so with SQL databases, NoSQL (Not only SQL) cloud databases are good candidates either. On the one hand, they usually provide enough space to store the typically larger ciphertexts and special indexes of PPE-schemes. On the other hand in...

OBJECTIVE Infection of the pleural cavity and development of empyema are potential dangers after pneumonectomy. In spite of decrease in frequency of postpneumonectomy empyemas (PPE) formation, this is still a serious complication. The aim of this study was: analysis the mechanisms of postpneumonectomy empyema formation and attempt the elaboration of the optimal management of these patients. M...

This study describes the use of microdialysis technique for continuous measurement of plasma protein extravasation (PPE) in rat and mouse skin with drug application either intravenously or via the microdialysis fiber. Hollow plasmapheresis fibers (3-cm length, 0.4-mm diameter, cutoff 3,000 kDa) were placed subcutaneously on the back of anesthetized mice and rats. Intravenous injection of dextra...

BACKGROUND Chronic obstructive pulmonary disease (COPD) is characterized by pulmonary inflammation, airways obstruction and emphysema, and is a risk factor for cardiovascular disease (CVD). However, the contribution of these individual COPD components to this increased risk is unknown. Therefore, the aim of this study was to determine the contribution of emphysema in the presence or absence of ...

This study aimed to evaluate practical barriers to personal protective equipment (PPE) use found through health care personnel (HCP) training sessions held during and after the 2015 Middle East respiratory syndrome outbreak in Korea. Difficulties observed were ill-fitting sizes, anxiety, confusion from unstandardized protocols, doubts about PPE quality and effectiveness, and complexity of using...

Mycobacterium tuberculosis (Mtb), possesses at least three type VII secretion systems, ESX-1, -3 and -5 that are actively involved in pathogenesis and host-pathogen interaction. We recently showed that an attenuated Mtb vaccine candidate (Mtb Δppe25-pe19), which lacks the characteristic ESX-5-associated pe/ppe genes, but harbors all other components of the ESX-5 system, induces CD4+ T-cell immu...

This paper presents the design and analysis of an areaefficient programmable processing element (PPE) for implementing diverse cryptographic systems and diverse bitwidths (currently 16, 32, and 64). To evaluate the effectiveness of our design, we implement π-Cipher and BMW on the PPE. π-Cipher is a new algorithm for authenticated encryption that offers advantages over AES-GCM and is a candidate...

AIM To determine the immediate surgical outcome and recovery of bowel function following posterior pelvic exenteration (PPE) for primary rectal cancer with suspected local invasion to the female internal reproductive organs, in comparison with a case-control series of standard resection for primary rectal cancer. METHODS We analyzed 10 consecutive female patients undergoing PPE for the aforem...

STUDY OBJECTIVES To assess serum amyloid alpha (SAA) pleural fluid levels in parapneumonic effusion (PPE) and to investigate SAA diagnostic performance in PPE diagnosis and outcome. METHODS We studied prospectively 57 consecutive patients with PPE (empyema (EMP), complicated (CPE), and uncomplicated parapneumonic effusion (UPE)). SAA, CRP, TNF-α, IL-1β, and IL-6 levels were evaluated in serum...
