#1
H-J Woitowitz, X Baur
Although there is no dispute among independent scientists about the carcinogenic and fibrogenic effects of chrysotile, the asbestos industry has been continuously and successfully acting to cast doubts on its harm. Another approach including asbestos insurance entities is to refuse compensation by raising the bar and fight criminal prosecution for asbestos-related diseases by the help of paid scientists. A recent publication on asbestos fibre burden in human lungs fits well in this context. The claim that chrysotile fibres are biopersistent in human lung is not based on the data provided by these authors, and, additionally, exhibits serious inconsistencies and obvious mismeasurements and significant methodological problems...

BACKGROUND & AIMS: There have been few studies of abdominal imaging screening of individuals at high risk for pancreatic cancer (based on family history or genetic variants). We performed a meta-analysis of prospective cohort studies to determine the diagnostic yield and outcomes of abdominal imaging screening for asymptomatic individuals at high risk. METHODS: Through a systematic review of multiple electronic databases and conference proceedings through July 2017, we identified prospective cohort studies (>20 patients) of asymptomatic adults determined to be at high-risk of pancreatic cancer (lifetime risk >5%, including specific genetic-associated conditions) who were screened by endoscopic ultrasound (EUS) and/or magnetic resonance imaging (MRI) to detect pancreatic lesions...

pH responsive luminescent copper nanoclusters (Cu NCs) with aggregation induced emission (AIE) characteristics have been synthesized. Upon internalization into living cells, the NCs displayed cellular pH environment dependent luminescence change with orange-red emission at pHi 4.5 while bright green emission was observed over time at pHi 7.4, through their AIE attributes. Further, the intracellular AIE kinetics of the NC probe was measured in MCF-7 cells and compared with HEK-293 cells. Intriguingly, intracellular rate constant value derived for AIE kinetics in MCF-7 cells was found 3-fold higher than that in HEK-293 cell lines, whereas the value was 2-fold higher than that observed in the aqueous medium...

The high incidence rates of prostate cancer (PCa) raise demand for improved therapeutic strategies. Prostate tumors specifically express the prostate-specific membrane antigen (PSMA), a membrane-bound protease. As PSMA is highly overexpressed on malignant prostate tumor cells and as its expression rate correlates with the aggressiveness of the disease, this tumor-associated biomarker provides the possibility to develop new strategies for diagnostics and therapy of PCa. Major advances have been made in PSMA targeting, ranging from immunotherapeutic approaches to therapeutic small molecules...

BACKGROUND: Nigeria commenced a phased programmatic deployment of rapid diagnostic tests (RDT) at the primary health care (PHC) facility levels since 2011. Despite various efforts, the national testing rate for malaria is still very low. The uptake of RDT has been variable. This study was undertaken to determine the provider and patient perceptions to RDT use at the PHC level in Nigeria with their implications for improving uptake and compliance. METHODS: A cross-sectional survey was conducted in 120 randomly selected PHCs across six states, across the six-geopolitical zones of Nigeria in January 2013...

Ultrasound contrast-enhanced stress echocardiography improves endocardial visualization, but diagnostic test rates versus stress myocardial perfusion imaging (MPI) have not been studied. A prospective randomized trial was performed between April 2012 and October 2014 at a single-center, safety net hospital. Hospitalized patients referred for noninvasive stress imaging were randomized 1:1 to stress echocardiography or stress MPI. The primary outcome was diagnostic test rate defined as interpretable images and achievement of >85% of age-predicted maximal heart rate (for dobutamine and exercise)...

The design and fabrication of reconfigurable, modular paperfluidics driven by a prefabricated reusable block library, asynchronous modular paperfluidic linear instrument-free (Ampli) block, are reported. The blocks are inspired by the plug-and-play modularity of electronic breadboards that lower prototyping barriers in circuit design. The resulting biochemical breadboard is a paperfluidic construction set that can be functionalized with chemical, biological, and electrical elements. Ampli blocks can form standard paperfluidic devices without any external instrumentation...

INTRODUCTION: Development of digital breast tomosynthesis (DBT) provides a technology that generates three-dimensional data sets, thus reducing the pitfalls of overlapping breast tissue. Observational studies suggest that the combination of two-dimensional (2D) digital mammography and DBT increases diagnostic accuracy. However, because of duplicate exposure, this comes at the cost of an augmented radiation dose. This undesired adverse impact can be avoided by using synthesised 2D images reconstructed from the DBT data (s2D)...

BACKGROUND: Hepatitis B virus (HBV) causes chronic liver-associated diseases and its early detection is of high public health importance. Its diagnosis is mainly based on immunological assays among which Enzyme-Linked Immunosorbent Assay (ELISA) and rapid tests are the most common and widespread methods. However, a major challenge is the discordance of results of any two laboratory assays which cannot be easily resolved. Therefore, this study was designed to evaluate the validity and reliability of commercially available five rapid test kits in comparison with two Enzyme Immunoassays (EIAs) in Nigeria using hepatitis B surface antigen as a reference marker...
