our meta-analysis suggest that EOS AECOPD patients have a better clinical outcome than non-EOS AECOPD patients in terms of length of hospital stay, in-hospital mortality, FEV1, and risk of arrhythmias. In addition, the non-EOS AECOPD patients have higher percentage of male than EOS AECOPD patients.
  Diagnostic yield (DY) and safety of computed tomography (CT)- and thoracic ultrasound (TUS)-guided biopsies in the diagnosis of pleural lesions have been investigated in a number of studies, but no synthesis of data from the literature has ever been performed.
 
  We aimed to provide the first systematic review and meta-analysis on the DY and safety of CT- versus TUS-guided biopsy in the diagnosis of pleural lesions.
 
  We searched MEDLINE and EMBASE for all studies reporting outcomes of interest published up to April 2018. Two authors reviewed all titles/abstracts and retrieved selected full text to identify studies according to predefined selection criteria. Summary estimates were derived using the random-effects model. Cumulative meta-analysis assessed the influence of increasing adoption of the procedures over time.
 
  Thirty original studies were included in the present review; the number of studies on TUS-guided biopsy was almost three-fold higher than those on CT-guided biopsy. The pooled DYs of the 2 procedures were overall excellent and differed <10%, being 84% for TUS-guided biopsy and 93% for CT-guided biopsy. Safety profiles were reassuring for both the techniques, being 7 and 3% for CT- and TUS-guided biopsy, respectively. DY of ultrasound technique significantly improved over time, while no time effect was observed for CT-guided biopsy.
 
  Data show that CT- and TUS-guided biopsies in the diagnosis of pleural lesions are both excellent procedures, without meaningful differences in DYs and safety. Considering that TUS is non-ionizing and easily performed at the bedside, it should be the preferred approach in presence of adequate skills.

In this paper, we propose to electrochemically transform the alkaline polyelectrolyte solution of DNA into DNA nanospheres (EsDNA). The result showed that stable DNA nanospheres for at least two months at 4 OC were successfully electro synthesized. UV-visible spectra of the prepared nanospheres revealed an emerged peak ranged from 372-392 nm depending on the DNA concentration and from 361 to 398.3 nm depending on electrospherization time. This result confirmed with size distribution curves figured out from TEM images, introduced that with increasing electrospherization time (6, 12 and 24 hrs.) induces a growing in the average size of DNA nanospheres (48, 65.5 and 117 nm, respectively). In addition, it introduced that the average size of DNA nanospheres become larger (37.8, 48 and 76.5 nm) with increasing DNA concentration (0.05, 0.1 and 0.2 wt.%) respectively. Also, our resns.The magnetotransport properties of a hybrid InSe/monolayer graphene in a SiC system are systematically studied. Compared to those of its bare graphene counterpart, in InSe/graphene, we can effectively modify the carrier density, mobility, effective mass, and electron-electron (e-e) interactions enhanced by weak disorder. We show that in bare graphene and hybrid InSe/graphene systems, the logarithmic temperature (lnT) dependence of the Hall slope R H = δR xy /δB = δρ xy /δB can be used to probe e-e interaction effects at various temperatures even when the measured resistivity does not show a lnT dependence due to strong electron-phonon scattering. Nevertheless, one needs to be certain that the change of R H is not caused by an increase of the carrier density by checking the magnetic field position of the longitudinal resistivity minimum at different temperatures. Given the current challenges in gating graphene on SiC with a suitable dielectric layer, our results suggest that capping a van der Waals material on graphene is an effective way to modify the electronic properties of monolayer graphene on SiC.As a low-energy effective theory on non-symmorphic lattices, we consider a generic triple point fermion Hamiltonian which is parameterized by an angular parameter $\lambda$. We find strong $\lambda$ dependence in both Drude and interband optical absorption of these systems. The deviation of the $T^2$ coefficient of the Drude weight from Dirac/Weyl fermions can be used as a quick way to optically distinguish the triple point degeneracies from the Dirac/Weyl degeneracies. At the particular $\lambda=\pi/6$ point, we find that the "helicity" reversal optical transition matrix element is identically zero. But deviating from this point, the helicity reversal emerges as an absorption channel.Recently, CuO has been proposed as a potential multiferroic material with high transition temperature. Competing models based on spin current and ionic displacements are invoked to explain ferroelectricity in CuO. The theoretical model based on ionic displacement predicted very small displacement (∼10-5Å) along thebaxis. Experimentally detecting displacements of such a small amplitude in a particular direction is extremely challenging. Through our detailed angle resolved polarized Raman spectroscopy study on single crystal of CuO, we have validated the theoretical study and provided direct evidence of displacement along thebaxis. Our study provides important contribution in the high temperature multiferroic compounds and showed for the first time, the use of the polarized Raman scattering in detecting ionic displacements at the femtometer scale.Synchrotron Radiotherapy (SyncRT) is a preclinical radiation treatment which delivers synchrotron x-rays to cancer targets. SyncRT allows for novel treatments such as Microbeam Radiotherapy, which has been shown to have exceptional healthy tissue sparing capabilities while maintaining good tumour control. Veterinary trials in SyncRT are anticipated to take place in the near future at the Australian Synchrotron's Imaging and Medical Beamline (IMBL).  https://www.selleckchem.com/products/ABT-869.html  However, before veterinary trials can commence, a computerised treatment planning system (TPS) is required, which can quickly and accurately calculate the synchrotron x-ray dose through patient CT images. Furthermore, SyncRT TPS's must be familiar and intuitive to radiotherapy planners in order to alleviate necessary training and reduce user error. We have paired an accurate and fast Monte Carlo (MC) based SyncRT dose calculation algorithm with EclipseTM, the most widely implemented commercial TPS in the clinic. Using EclipseTM, we have performed preliminary SyncRT trials on dog cadavers at the IMBL, and verified calculated doses against dosimetric measurement to within 5% for heterogeneous tissue-equivalent phantoms.
