Effectiveness of Different Topical Treatments in the Healing of Pressure Injuries: A Network Meta-analysis.
(
Elsevier
, 2018 , Article)
Pressure injuries (PIs) are one of the most common types of complex wounds and impose a huge economic burden on the healthcare system and the patients. A plethora of topical treatments is widely available for PI treatment, ...
P-value driven methods were underpowered to detect publication bias: analysis of Cochrane review meta-analyses
(
Elsevier
, 2019 , Article)
To investigate the effect of number of studies in a meta-analysis on the detection of publication bias using p-value driven methods. The proportion of meta-analyses detected by Egger's, Harbord's, Peters', and Begg's tests ...
PD-L1 status in breast cancer: Current view and perspectives.
(
Elsevier
, 2019 , Article)
Breast cancer was traditionally not considered a particularly immunogenic tumor. However, recent developments have shown that some aggressive triple-negative breast cancers are immunogenic, exhibit a resistance to chemotherapy ...
Bentonite-decorated calix [4] arene: A new, promising hybrid material for heavy-metal removal
(
Elsevier
, 2018 , Article)
There is global concern about the contamination of ground, river, and tap waters as well as soil contamination with heavy metal ions; these chemical species are known to not degrade and to cause severe health problems if ...
Generation of photo charge in poly(ethyleneimine)-TiO2-anthocyanin modified papers conditioned at different humidities.
(
Elsevier
, 2018 , Article)
The article describes the influence of humidity on the surface photodielectric properties of papers prepared from poly(ethyleneimine)-TiO2 nanoparticles-anthocyanin modified cellulose fibres. The anthocyanins were extracted ...

Effect of halloysite nano tubes on the thermal degradation behaviour of PCL/PLA microfibrillar composites
(
Elsevier
, 2017 , Article)
This paper reports on the thermal degradation behaviour and kinetics of halloysite nanotubes containing microfibrillated poly(ε-caprolactone) (PCL)/poly(lactic acid) (PLA) blends. It was found that the nanotubes probably ...
Preparation and characterisation of Ce:YAG -polycarbonate composites for white LED.
(
Elsevier
, 2016 , Article)
Ce:YAG-polycarbonate composites were prepared with several amounts of Ce:YAG in the range 0.1
e5 wt.% by using melt compounding. The structure and morphology of the composites were investigated by means of X-ray diffractometry ...
Thermal and mechanical properties of PP/HDPE/wood powder and MAPP/HDPE/wood powder polymer blend composites.
(
Elsevier
, 2017 , Article)
The morphology and properties of blends of PP/HDPE and MAPP/HDPE blends, and their composites with wood
powder, were investigated in this paper. The blends showed two-phase morphologies, and MAPP interacted
better than ...
