Pemigatinib is an oral, selective, potent, competitive inhibitor acting on fibroblast growth factor receptor (FGFR)1, FGFR2, and FGFR3, which has obtained accelerated approval in the USA through a test approved by the USA FDA. It is not only significant in the therapy of adult recurrent, unresectable, metastatic or locally advanced cholangiocarcinoma, but also plays an important role in treating adult patients with FGFR2 fusion or other rearrangements. The aim of our research was to establish and verify a reliable and quick ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) assay to determine the level of pemigatinib in rat plasma. The analyte was prepared using a simple and convenient approach with acetonitrile for protein crash, and then separated from the matrix on a Waters Acquity UPLC BEH C18 column (2.1 mm × 50 mm, 1.7 μm) in a gradient elution program, where the mobile phase was consisted of acetonitrile and 0.1 % formic acid in water and was set at 0.40 mL/min flow rate. this website Selective reaction monitoring (SRM) was used to conducted for UPLC-MS/MS dectection with ion transitions at m/z 488.01 → 400.98 for pemigatinib and m/z 447.00 → 361.94 for erdafitinib (Internal standard, IS), respectively. This method had good linearity in a 0.5-1000 ng/mL calibration range for pemigatinib, where the lower limit of quantification (LLOQ) was validated at 0.5 ng/mL. The precision of pemigatinib for intra- and inter-day was less than 13.3 %, and the accuracy was determined to be from -4.8%-11.2%. During the assay in plasma samples, the analyte was found to be stable. Besides, matrix effect and recovery of the analyte and IS were acceptable. The novel optimized UPLC-MS/MS assay was also suitable for determining the concentration level of pemigatinib in a pharmacokinetic study after a single dose of 1.35 mg/kg pemigatinib orally to the rats.A rapid ultra-high performance liquid chromatography coupled with triple quadrupole tandem mass spectrometry (UHPLC-QqQ MS/MS) approach with high sensitivity and selectivity was developed for the quantification of twenty compounds, including 9 saponins, 8 flavonoids, 2 oligosaccharide esters and 1 phenolic acid, in rat plasma and brain, which was administrated intragastrically with Jia-Wei-Qi-Fu-Yin (JWQFY), Mass spectrometric detection was operated under multiple reaction monitoring (MRM) mode. All calibration curves possessed good linearity with correlation coefficients ( r2) higher than 0.9916 in their respective linear ranges. For intra- and inter-day precision, all the relative standard deviations (RSDs) at different levels were less than 14.68 %. Based on the UHPLC-QqQ MS/MS quantitative results, pharmacokinetic study and brain distribution of multiple components in JWQFY was then successfully performed. As a result, constituents with discrepancy structures showed diverse pharmacokinetic and distribution characteristics. For instance, ferulic acid (phenolic acid), 3, 6'-disinapoyl sucrose and tenuifoliside A (oligosaccharide esters) showed short Tmax ( 4 h). Besides, ferulic acid, epimedin C, icariin, glycyrrhizin, ginsenoside Rb1 and ginsenoside Rg1 were considered as the potential effective ingredients of JWQFY because of their relatively high exposure to blood and brain. Our study would provide relevant information for discovery of pharmacodynamic ingredients, as well as further action mechanisms investigations of JWQFY.
The effects of burnout can have serious consequence for individual nurse's, patients and healthcare organisations. The aim of this study was to assess prevalence and predictors of burnout and work-life balance amongst haemato-oncology nurses.
This study employed a cross-sectional survey design. Haematology cancer nurses attending a 2-day conference in Ireland, during Oct 2019 were recruited. Anonymised data were collected on 1) socio-demographics and occupational variables, 2) burnout using Maslach Burnout Inventory and 3) satisfaction with work-life balance.
There was an 80.4% survey completion rate (n=78 of 97). One-third of haemato-oncology nurses reported high levels of emotional exhaustion, with an additional 46% experiencing moderate levels. Despite this, 64% of nurses highlighted a moderate or high level of personal accomplishment. Demographics such as <40yrs old, unmarried, working ≥25hrs per week and having 6-10 years' experience in haemato-oncology, all showed trends towards increased burnoldren, working in in-patient settings, have identified a need for greater flexibility with working conditions, to improve work-life balance.Fasciola hepatica is a trematode infecting ruminants worldwide, occasionally reported in a wide range of animal species, including humans. According to the WHO, fasciolosis is recognized as a re-emerging neglected tropical disease, responsible for endemic and epidemic outbreaks in humans. Although the main hosts of the parasite are represented by cattle, sheep and goats, wildlife may be involved in its circulation. Here we firstly report F. hepatica in a wild boar from Italy (southern area) and characterize it both morphologically and molecularly. The nad1 gene analysis of specimens analyzed, revealed a high genetic similarity with those of humans from Iran and Peru, as well as a close phylogenetic relationship to those in ruminants from Brazil, Ecuador and Egypt. Considering the increase in the wild boar populations in urban and peri-urban areas, a potential role of this ungulate in the circulation of this zoonotic trematode is suggested.In the Moroccan Middle Atlas, the tailings rich in lead and other metal residues, in the abandoned Zaida mining district, represent a real threat to environment and the neighboring villages' inhabitants' health. In this semi-arid to arid area, phytostabilisation would be the best choice to limit the transfer of heavy metals to populations and groundwater. The aim of this work was to characterize the bacteria that nodulate Retama sphaerocarpa, spontaneous nitrogen fixing shrubby legume, native to the Zaida mining area, with great potential to develop for phytostabilisation. Forty-three bacteria isolated from root nodules of the plant were characterized. Based on REP-PCR and ARDRA, four strains were selected for further molecular analyzes. The 16S rRNA gene sequences analysis revealed that the isolated strains are members of the genus Bradyrhizobium, and the phylogenetic analysis of the housekeeping genes glnII, atpD, gyrB, rpoB, recA and dnaK individual sequences and their concatenation showed that the strains are close to B.
