From 2011 to 2014, the BESIII experiment collected about 5 fb^-1 data at center-of-mass energies around 4 GeV for the studies of the charmonium-like and higher excited charmonium states. By analyzing ...the di-muon process e＋e- →yma/Fsμ^＋μ^-, the center-of-mass energies of the data samples are measured with a precision of 0.8 MeV. The center-of-mass energy is found to be stable for most of the time during data taking.
We report the first observation of D+ → τ+ντ with a significance of 5.1σ. We measure B(D+ → τ+ντ ) = (1.20 ± 0.24stat ± 0.12syst) × 10–3. Taking the world average B(D+ → μ+ντ ) = (3.74 ± 0.17) × ...10–4, we obtain Rτ/μ = Γ(D+ → τ+ντ )/Γ(D+ → μ+ντ) = 3.21 ± 0.64stat ± 0.43syst, which is consistent with the Standard Model expectation of lepton flavor universality. Using external inputs, our results give values for the D+ decay constant fD+ and the CKM matrix element |Vcd| that are consistent with, but less precise than, other determinations.
This study investigated the effects of supplementation of various sources of Met and Lys on nutrient digestion, N utilization, and duodenal AA flows in growing goats. Four 4-mo-old Liuyang Black ...wether goats were used in a 4 x 4 Latin square experiment and were assigned to 4 dietary treatments: (1) control, (2) control + lipid-coated Met-Zn chelate and Lys-Mn chelate (PML), (3) control + Met-Zn chelate and Lys-Mn chelate (CML), and (4) control + DL-Met, L-Lys-HCl, ZnSO₄·7H₂O, and MnSO₄·H₂O (FML). Compared with control, PML reduced (P < 0.05) ruminal NH₃ concentration, urinary N excretion, and plasma urea N concentration and increased (P < 0.05) the activity of ruminal endo-1,4-β-D-glucanase and β-glucosidase, the duodenal flow of N, N retention (g/d as well as % of absorbed N), the duodenal flows of Met, Lys, His, Val, and total essential AA, and plasma concentrations of Lys, Val, Phe, and total essential AA. Supplementing Zn-Met and Mn-Lys chelates had similar (P > 0.05) but lesser effects on these measures compared with PML, and the effects on most of the measures were not statistically significant (P > 0.05) when compared with control. Supplementing free-form Met and Lys had no effects compared with control (P > 0.05). The results indicate that lipid coating and chelating of AA provide a protection, and to a lesser extent by only chelating, of the AA from microbial degradation in the rumen and possibly has effects on rumen fermentation, which increases MP supply. This technology could improve productive performance and be of potential benefit to ruminant production if cost-effective products are developed.
We report the first measurement of the absolute branching fraction for Λc+→Λμ+νμ. This measurement is based on a sample of e+e− annihilation data produced at a center-of-mass energy s=4.6 GeV, ...collected with the BESIII detector at the BEPCII storage rings. The sample corresponds to an integrated luminosity of 567 pb−1. The branching fraction is determined to be B(Λc+→Λμ+νμ)=(3.49±0.46(stat)±0.27(syst))%. In addition, we calculate the ratio B(Λc+→Λμ+νμ)/B(Λc+→Λe+νe) to be 0.96±0.16(stat)±0.04(syst).
Different surface morphologies on AISI 304 stainless steel have been obtained after millisecond Nd:YAG pulsed laser oxidation. The effects of laser processing parameters, especially pulse width and ...laser energy density on the surface morphologies of the stainless steel were emphatically investigated. The results showed that surface morphologies were significantly changed with increasing laser pulse widths and laser energy densities. When the pulse width was 0.2–1.0
ms and laser energy density was 4.30×10
6–7.00×10

2, the surface was obviously damaged and the morphologies varied gradually from craters to ripple structures. However, when the pulse width was longer than 1
ms and the laser energy density was increased from 1.90×10
7 to 3.16×10

J/m
2, the sizes of craters got smaller until disappeared and the surface became flatter and smoother. Nevertheless, the smooth surface was not obtained under overhigh laser energy densities. In addition, the schematic relationship was used to describe the formation process and mechanism of different surface morphologies.
▶ Surface temperature fields are established by a analytical model under different pulse widths. ▶ Effects of the laser parameters on surface morphologies of the stainless steel are revealed. ▶ Formation process and mechanism of different surface morphologies are illustrated.
In this paper, a novel drug carrier for brain delivery, cationic bovine serum albumin (CBSA) conjugated with poly(ethyleneglycol)–poly(lactide) (PEG–PLA) nanoparticle (CBSA–NP), was developed and its ...effects were evaluated. The copolymers of methoxy-PEG–PLA and maleimide-PEG–PLA were synthesized by ring opening polymerization of
d,l-lactide initiated by methoxy-PEG and maleimide-PEG, respectively, which were applied to prepare pegylated nanoparticles by means of double emulsion and solvent evaporation procedure. Native bovine serum albumin (BSA) was cationized and thiolated, followed by conjugation through the maleimide function located at the distal end of PEG surrounding the nanoparticle's surface. Transmission electron micrograph (TEM) and dynamic light scattering results showed that CBSA–NP had a round and regular shape with a mean diameter around 100 nm. Surface nitrogen was detected by X-ray photoelectron spectroscopy (XPS), and colloidal gold stained around the nanoparticle's surface was visualized in TEM, which proved that CBSA was covalently conjugated onto its surface. To evaluate the effects of brain delivery, BSA conjugated with pegylated nanoparticles (BSA–NP) was used as the control group and 6-coumarin was incorporated into the nanoparticles as the fluorescent probe. The qualitative and quantitative results of CBSA–NP uptake experiment compared with those of BSA–NP showed that rat brain capillary endothelial cells (BCECs) took in much more CBSA–NP than BSA–NP at 37 °C, at different concentrations and time incubations. After a dose of 60 mg/kg CBSA–NP or BSA–NP injection in mice caudal vein, fluorescent microscopy of brain coronal sections showed a higher accumulation of CBSA–NP in the lateral ventricle, third ventricle and periventricular region than that of BSA–NP. There was no difference on BCECs' viability between CBSA-conjugated and -unconjugated pegylated nanoparticles. The significant results in vitro and in vivo showed that CBSA–NP was a promising brain drug delivery carrier with low toxicity.
IL-36γ is considered to be a valuable biomarker in psoriatic patients, which is expressed as an inactive precursor that needs to be proteolytically processed and activated, and neutrophil-derived ...proteases seemed to be potent activating enzymes of IL-36γ.
This study aims to investigate the activation of IL-36γ by cathepsin G (CG) and neutrophil elastase (NE).
We used inactive recombinant full-length (FL)-IL-36γ with different doses of NE or CG to stimulate HaCaT cells; neutrophil extracellular traps (NETs) were prepared to act on FL-IL-36γ and then stimulate HaCaT cells. Real-time quantitative PCR and ELISA were performed to detect CXCL-1 and CXCL-8 expression. We developed imiquimod-induced psoriasis-like mouse model to evaluate the effect of hypodermic injection of neutrophil-derived protease or its inhibitor. Histopathology and Western blotting were conducted for effect assessment.
Purified CG cleaved and activated recombinant human FL-IL-36γ to promote CXCL-1 and CXCL-8 expression by human keratinocytes, and NETs activated FL-IL-36γ and the activation was inhibited by serpin A3. CG induced expression of a more truncated IL-36γ in psoriasiform lesion of mice and aggravated the psoriasis-like lesion induced by imiquimod, whereas recombinant serpin A3 alleviated the severity of the psoriasis-like mouse mode.
CG has the ability to cleave and activate IL-36γ and aggravate imiquimod-induced mouse psoriasiform lesion. Thus, CG-specific inhibitors might be promising therapeutic drugs for psoriasis.
Based on 586 pb−1 of e+e− annihilation data collected at a center-of-mass energy of s=4.6GeV with the BESIII detector at the BEPCII collider, the absolute branching fraction of Λc+→pKS0η decays is ...measured for the first time to be B(Λc+→pKS0η)=(0.414±0.084±0.028)%, where the first uncertainty is statistical and the second is systematic. The result is compatible with a previous CLEO result on the relative branching fraction B(Λc+→pKS0η)B(Λc+→pK−π+), and consistent with theoretical predictions of SU(3) flavor symmetry.
