Metabolic fingerprinting of Angelica sinensis during growth using UPLC-TOFMS and chemometrics data analysis
BACKGROUND: The radix of Angelica sinensis is widely used as a medicinal herbal and metabolomics research of this plant during growth is necessary. RESULTS: Principal component analysis of the UPLC-QTOFMS data showed that these 27 samples could be separated into 4 different groups. The chemical markers accounting for these separations were identified from the PCA loadings plot. These markers were further verified by accurate mass tandem mass and retention times of available reference standards. The study has shown that accumulation of secondary metabolites of Angelica sinensis is closely related to the growth periods. CONCLUSIONS: The UPLC-QTOFMS based metabolomics approach has great potential for analysis of the alterations of secondary metabolites of Angelica sinensis during growth
Large-area, freestanding single-crystal gold of single nanometer thickness
Two-dimensional single-crystal metals are highly sought after for
next-generation technologies. Here, we report large-area (>10^4 {\mu}m2),
single-crystal two-dimensional gold with thicknesses down to a single-nanometer
level, employing an atomic-level-precision chemical etching approach. The
ultrathin thickness and single-crystal quality endow two-dimensional gold with
unique properties including significantly quantum-confinement-augmented optical
nonlinearity, low sheet resistance, high transparency and excellent mechanical
flexibility. By patterning the two-dimensional gold into nanoribbon arrays,
extremely-confined near-infrared plasmonic resonances are further demonstrated
with quality factors up to 5. The freestanding nature of two-dimensional gold
allows its straightforward manipulation and transfer-printing for integration
with other structures. The developed two-dimensional gold provides an emerging
platform for fundamental studies in various disciplines and opens up new
opportunities for applications in high-performance ultrathin optoelectronic,
photonic and quantum devices
Clinical analysis of decision implementation by a multidisciplinary team in cervical cancer cases in Ganzhou, China
ObjectiveIn this study, we evaluated the role of a multidisciplinary team (MDT) in clinical practice for cervical cancer by analyzing the development of a single-case multidisciplinary consultation for cervical cancer.MethodsPatients in MDT consultations for cervical cancer were retrospectively analyzed for clinical information, decision content of MDT discussion, implementation, and follow-up results.ResultsOf the 392 patients who met the inclusion criteria, 359 had a first episode, of which 284 were stage IA-IIA2 (79.11%) and 75 were stage IIB-IVB (20.89%). Of these 392, 33 had a recurrence (8.42%). A total of 416 cases were analyzed, and neoadjuvant chemotherapy with surgery was recommended in 43 cases, of which 40 cases were implemented, and 36 of the 40 achieved the expected outcome. Surgical treatment was recommended in 241 cases, of which 226 underwent surgery, and 215 of them achieved the expected outcome. Radiotherapy was recommended in 31 cases, of which 26 cases underwent it, and 22 of them achieved the expected efficacy. Concurrent chemoradiotherapy was recommended in 57 cases, of which 49 underwent it, and 39 of them achieved the expected efficacy. Other treatments were recommended in 44 cases, of which 23 cases were implemented, and 10 of them achieved the expected efficacy, with statistically significant differences compared with cases without implementation (P <0.05). MDT decisions were correlated with age; the younger the patients, the higher the implementation efficiency (P <0.05). The difference between MDT expectation in all implementation and partial implementation and age was statistically significant (P <0.05). No significant difference was found between age and MDT expectation in all not fully implemented decisions (P >0.05). Some decisions were not fully implemented due to economic status and fear of certain treatments of the patient.ConclusionThe MDT plays an important role in clinical practice such as clinical staging, treatment plan, and the complete treatment management of patients with cervical cancer, which can significantly improve the near-term treatment effect, whereas its effect on a long-term prognosis needs further clinical observation and active exploration
A Measurement of Psi(2S) Resonance Parameters
Cross sections for e+e- to hadons, pi+pi- J/Psi, and mu+mu- have been
measured in the vicinity of the Psi(2S) resonance using the BESII detector
operated at the BEPC. The Psi(2S) total width; partial widths to hadrons,
pi+pi- J/Psi, muons; and corresponding branching fractions have been determined
to be Gamma(total)= (264+-27) keV; Gamma(hadron)= (258+-26) keV, Gamma(mu)=
(2.44+-0.21) keV, and Gamma(pi+pi- J/Psi)= (85+-8.7) keV; and Br(hadron)=
(97.79+-0.15)%, Br(pi+pi- J/Psi)= (32+-1.4)%, Br(mu)= (0.93+-0.08)%,
respectively.Comment: 8 pages, 6 figure
Psi(2S) two- and three-body hadronic decays
We report measurements of branching fractions for psi(2S) decays into omega
pi pi, b1 pi,omega f2(1270),omega KK, omega p pbar, phi pi pi, phi f0(980),phi
KK, and an upper limit for phi p pbar final states based on a data sample of 4
X 10^6 psi(2S) events collected with the BESI detector at the Beijing
Electron-Positron Collider. The branching fractions for b1 pi and omega
f2(1270) update previous BES results, while those for other decay modes are
first measurements. The ratios of psi(2S)and J/psi branching fractions are
smaller than what is expected from the 12% rule by a factor of five for omega
f2(1270),by a factor of two for omega pi pi, omega p pbar, and phi KK, while
for other studied channels the ratios are consistent with expectation within
errors.Comment: 9 pages,12 figures and 1 tabl
