Abstract Background Characterization of breast cancer phenotypes has improved our ability to predict breast cancer behavior. Triple-negative (TN) breast cancers have higher and earlier rates of distant events. It has been suggested that this behavior necessitates treating TNs faster than others, including use of neoadjuvant chemotherapy (NACT) if time to surgery is not rapid. ...

Abstract A Gram-stain-negative, rod-shaped bacterial strain JS15-10A1T was isolated from oil production water. Its optimum growth was observed at 37 °C, pH 7.0, and 3% (w/v) NaCl. The 16S rRNA gene sequence of strain JS15-10A1T showed the highest similarities with Pseudomonas parafulva CB-1T (97.6%) and P. fulva IAM 1529T (97.5%). In addition, phylogenetic analyses based on multilocus sequence analyses with concatenating 16S rRNA, gyrB, rpoD, and rpoB genes indicated that strain...

Abstract Lithium (Li) exploitation for industrial and domestic use is resulting in a buildup of the element in various environmental components that results in potential toxicity to living systems. Therefore, a soil culture experiment was conducted to evaluate the effects of increasing concentration of Li (0, 20, 40, 60, and 80 mg kg−1 soil) on spinach growth, the effects of Li uptake, and its effects on various physiological attributes of the crop. The results showed that lower...

Abstract This work investigated the use of acidified dealginated residue from Sargassum filipendula algae for biosorption of silver in fixed bed column. This biosorbent was esterified for carboxyl and sulfonate groups to investigate the influence of these groups on silver removal percentage. Potentiometric titration was also evaluated on acidified and esterified biosorbents. Porosity and specific weight were determined by helium picnometry and mercury porosimetry techniques. The...

Abstract A fast and sensitive SPE-LC-MS/MS method for the determination of acrolein in environmental water samples using activated charcoal as SPE adsorbent was developed. The novelty of this study consists in acrolein extraction, separation and detection without the need of a derivatization process. Physicochemical properties of acrolein, such as low molecular weight and high polarity represent real challenges for extraction, separation, and detection of this pollutant using SPE-LC-MS/MS....

Abstract Various adsorbents including agricultural waste–based adsorbents, nanomaterials and layered double hydroxides have been reviewed for removal of antibiotics from water due to their unique properties. The adsorption mechanism is governed mostly by the affinity of a pollutant to adsorbent materials. However, the main adsorption mechanisms defined in this study for removal of antibiotics are the electrostatic attraction, π–π interaction and hydrogen bonding. The study highlighted...

Abstract The efficient capture of CO2 is a critical problem for porous adsorbents. The inadequacy of conventional adsorbents has low adsorption capacity towards CO2 removal. Metal organic frame work has been considered as very effective for CO2 adsorption as it shows higher rate of CO2 adsorption at room temperature. In conventional amine processes, a comparatively high energy penalty is required, whereas a novel class of metal-organic framework by the combination of amine solvent...

Abstract Rapid urban growth and high population density have become a problem for urban water resources, especially in developing countries. In general, the pollution of rivers and degradation of ecosystems are the result of both management failures and lack of sewage treatment. River restoration appears as a solution to improve this scenario, but it is common for there to be an absence of a systemic vision in these projects. Thus, this work analysed one of these projects as an...

Abstract Poly(L-lactic acid) (PLLA) can be used as an external electron donor in denitrification reactors to treat drinking water, aquaculture water, and industrial wastewater with an imbalanced carbon/nitrogen ratio. However, for PLLA to function in these applications, its chemical hydrolyzability requires improvement. Although the adjustment of the crystallinity (Xc) is effective in improving the hydrolyzability of PLLA, the condition for the Xc of PLLA, in which a sufficient...

Zusammenfassung Onkologische Notfälle sind in der Ätiologie und Symptomatik vielfältig und treten häufig mit der Einleitung einer Chemotherapie auf, können sich aber auch während oder mit zeitlicher Verzögerung manifestieren. Die Kenntnis onkologischer Notfälle unter medikamentöser Tumortherapie ist daher nicht nur für die behandelnden Fachdisziplinen wichtig, sondern auch für mit- oder weiterbetreuende Kollegen. Jeder dieser Krankheitszustände erfordert eine sorgfältige Beurteilung...

Abstract Pollen analysis has long been used as a tool to make an assessment of regional vegetation. On-site pollen samples are taken for the same purpose at some excavations, because they are often the only available contexts with good preservation conditions. This paper shows that the analysis of on- and off-site pollen samples from the same region (West Frisia, the Netherlands) and time period (Dutch Bronze Age; ca. 2000–800 bc) can give very conflicting results on the type and...

Abstract The abuse of prescription opioid drugs is a well-documented and very serious problem. One of the typical first steps an abuser will take is to manipulate a tablet into to a fine powder. To deter this behavior, formulators use crush-resistant technologies like polyethylene oxide (PEO). When heat-treated, PEO creates a hard, flexible tablet that cannot be easily ground down into a fine powder. We investigated the effects of PEO molecular weight (MW), annealing temperature,...

Abstract The first in vitro tests for developmental toxicity made use of rodent cells. Newer teratology tests, e.g. developed during the ESNATS project, use human cells and measure mechanistic endpoints (such as transcriptome changes). However, the toxicological implications of mechanistic parameters are hard to judge, without functional/morphological endpoints. To address this issue, we developed a new version of the human stem cell-based test STOP-tox(UKN). For this purpose,...

Abstract Despite the consolidated belief that the macaque superior parietal lobule (SPL) is entirely occupied by Brodmann’s area 5, recent data show that macaque SPL also hosts a large cortical region with structural and functional features similar to that of Brodmann’s area 7. According to these data, the anterior part of SPL is occupied by a somatosensory-dominated cortical region that hosts three architectural and functional distinct regions (PE, PEci, PEip) and the caudal half...
