BackgroundThis study summarizes the clinical features of stroke in patients with prosthetic valve endocarditis (PVE) in China.MethodsThe clinical data of PVE patients admitted to Beijing Anzhen ...Hospital from January 1997 to August 2018 were retrospectively analyzed.ResultsIn total, 62 patients with PVE were enrolled (45 males, 17 females). The patients’ age ranged from 23 to 79 years (51.69 ± 15.01). Rheumatic heart disease (RHD) was the most common reason for valve replacement. Of the patients, 58 were found to have vegetations by echocardiography. Blood cultures revealed the most common pathogens to be Staphylococcus (12 cases) and fungal infections (n = 7); 18 (29.03%) patients had strokes. There were 12 cases of ischemic stroke, three cases of cerebral hemorrhage, one case of subarachnoid hemorrhage, and two cases of unclear etiology. The most commonly found clinical symptoms of stroke patients were hemiplegia (n = 10) and coma (n = 5). The five patients in coma died during hospitalization. The incidence of RHD, double valve replacement, atrial fibrillation, and mitral valve vegetation was significantly higher in the stroke group than in the non-stroke group (p = 0.045, 0.000, 0.033, and 0.045, respectively). Logistic regression analysis showed that the odds ratios (ORs) for RHD, double valve replacement, and fungal infection as risk factors of stroke were 7.26 (95% CI: 1.23–42.68), 25.60 (95%CI: 4.33–126.16), and 20.58 (95% CI: 2.13–198.82), respectively, and were statistically significant. Eight patients died during hospitalization and the in-hospital mortality was 12.90%. The OR for in-hospital mortality with concurrent stroke was 5.13 (95% CI: 1.08–24.46, p = 0.028).ConclusionStroke is a common complication in PVE that increases patient mortality. Rheumatic heart disease, double valve replacement, and fungal infection may be risk factors for patients with PVE complicated by stroke.
One of the major problems of p-i-n tunneling field-effect transistor (TFET) is the reliability due to the strong electric field near the tunneling junction. In this paper, using technology ...computer-aided design simulation, we show that the insertion of a thin n-layer into the tunneling junction of the p-i-n TFET (p-n-i-n TFET) not only enhances its drive current, as has been previously reported, but also improves its reliability. As compared with the conventional p-i-n TFET, we demonstrate the following properties of the p-n-i-n TFET: 1) The normal component of the electric field near the tunneling junction is reduced, and therefore, the field-driven interface-trap generation can be reduced. This can be further reduced by properly aligning the gate electrode with respect to the tunneling junction. 2) The threshold-voltage shift due to the dielectric charge generated near the tunneling junction is significantly reduced. 3) The variation of the threshold voltage to the oxide and bulk thickness variations is also reduced.
We studied the effect of fibroblast growth factor receptor 3 (FGFR3) inhibitor BGJ-398 on the differentiation of bone marrow mesenchymal stem cells (BM MSC) into osteoblasts in wild type (wt) mice ...and in animals with mutation in
TBXT
gene (mt) and possible differences in the pluripotency of these cells. Cytology tests showed that the cultured BM MSC could differentiate into osteoblasts and adipocytes. The effect of different BGJ-398 concentrations on the expression of
FGFR3
,
RUNX2
,
SMAD1
,
SMAD4
,
SMAD5
,
SMAD6
,
SMAD7
, and
SMAD8
were studied by quantitative reverse transcription PCR. The expression of
RUNX2
protein was evaluated by Western blotting. BM MSC of mt and wt mice did not differ in pluripotency and expressed the same membrane marker antigens. BGJ-398 inhibitor reduced the expression of
FGFR3
and
RUNX2
. In BM MSC from mt and wt mice have similar gene expression (and its changing) in
FGFR3
,
RUNX2
,
SMAD1
,
SMAD4
,
SMAD5
,
SMAD6
,
SMAD7
, and
SMAD8
genes. Thus, our experiments confirmed the effect of decreased expression of
FGFR3
on osteogenic differentiation of BM MSC from wt and mt mice. However, BM MSC from mt and wt mice did not differ in pluripotency and are an adequate model for laboratory research.
The recent discovery of superconductivity with a transition temperature (T(c)) at 18 K in K(x)picene has extended the possibility of high-T(c) superconductors in organic materials. Previous ...experience based on similar hydrocarbons, like alkali-metal doped phenanthrene, suggested that even higher transition temperatures might be achieved in alkali-metals or alkali-earth-metals doped such polycyclic-aromatic-hydrocarbons (PAHs), a large family of molecules composed of fused benzene rings. Here we report the discovery of high-T(c) superconductivity at 33 K in K-doped 1,2:8,9-dibenzopentacene (C(30)H(18)). To our best knowledge, it is higher than any T(c) reported previously for an organic superconductor under ambient pressure. This finding provides an indication that superconductivity at much higher temperature may be possible in such PAHs system and is worthy of further exploration.
The quantum entangled J/ψ→Σ^{+}Σover ¯^{-} pairs from (1.0087±0.0044)×10^{10} J/ψ events taken by the BESIII detector are used to study the nonleptonic two-body weak decays Σ^{+}→nπ^{+} and Σover ...¯^{-}→nover ¯π^{-}. The CP-odd weak decay parameters of the decays Σ^{+}→nπ^{+} (α_{+}) and Σover ¯^{-}→nover ¯π^{-} (αover ¯_{-}) are determined to be 0.0481±0.0031_{stat}±0.0019_{syst} and -0.0565±0.0047_{stat}±0.0022_{syst}, respectively. The decay parameter αover ¯_{-} is measured for the first time, and the accuracy of α_{+} is improved by a factor of 4 compared to the previous results. The simultaneously determined decay parameters allow the first precision CP symmetry test for any hyperon decay with a neutron in the final state with the measurement of A_{CP}=(α_{+}+αover ¯_{-})/(α_{+}-αover ¯_{-})=-0.080±0.052_{stat}±0.028_{syst}. Assuming CP conservation, the average decay parameter is determined as ⟨α_{+}⟩=(α_{+}-αover ¯_{-})/2=-0.0506±0.0026_{stat}±0.0019_{syst}, while the ratios α_{+}/α_{0} and αover ¯_{-}/αover ¯_{0} are -0.0490±0.0032_{stat}±0.0021_{syst} and -0.0571±0.0053_{stat}±0.0032_{syst}, where α_{0} and αover ¯_{0} are the decay parameters of the decays Σ^{+}→pπ^{0} and Σover ¯^{-}→pover ¯π^{0}, respectively.
Using (10087±44)×10^{6} J/ψ events collected with the BESIII detector, numerous Ξ^{-} and Λ decay asymmetry parameters are simultaneously determined from the process J/ψ→Ξ^{-}Ξover ...¯^{+}→Λ(pπ^{-})π^{-}Λover ¯(nover ¯π^{0})π^{+} and its charge-conjugate channel. The precisions of α_{Λ0} for Λ→nπ^{0} and αover ¯_{Λ0} for Λover ¯→nover ¯π^{0} compared to world averages are improved by factors of 4 and 1.7, respectively. The ratio of decay asymmetry parameters of Λ→nπ^{0} to that of Λ→pπ^{-}, ⟨α_{Λ0}⟩/⟨α_{Λ-}⟩, is determined to be 0.873±0.012_{-0.010}^{+0.011}, where the first and the second uncertainties are statistical and systematic, respectively. The ratio is smaller than unity more than 5σ, which signifies the existence of the ΔI=3/2 transition in Λ for the first time. Besides, we test for CP symmetry in Ξ^{-}→Λπ^{-} and in Λ→nπ^{0} with the best precision to date.
