Formation, stability, and adiabatic excitation of peakons and double-hump solitons in parity-time-symmetric Dirac-δ(x)-Scarf-II optical potentials.

We introduce a class of physically intriguing PT-symmetric Dirac-δ-Scarf-II optical potentials. We find the parameter region making the corresponding non-Hermitian Hamiltonian admit the fully real spectra, and present the stable parameter domains for these obtained peakons, smooth solitons, and double-hump solitons in the self-focusing nonlinear Kerr media with PT-symmetric δ-Scarf-II potentials. In particular, the stable wave propagations are exhibited for the peakon solutions and double-hump solitons from some given parameters even if the corresponding parameters belong to the linear PT-phase broken region.

An efficient method for measuring the internal parameters of optical cameras based on optical fibres.

In this work, we report an expedient auto-collimating method for self-measuring the internal parameters (IPs) of optical cameras. Several key optical components, including the thin optical fibre (TOF), reflecting prism, and receiver, are introduced into optical cameras. The TOF outgoing end and area-array image receiver are integrated onto the focal-plane assembly of optical cameras.

Human urine-derived stem cells contribute to the repair of ischemic acute kidney injury in rats.

Acute kidney injury (AKI) is a clinical syndrome associated with high rates of morbidity and mortality. It has previously been reported that stem cells may be considered a potential therapeutic strategy for the treatment of AKI. The present study aimed to determine whether administration of urine‑derived stem cells (USCs) to rats with ischemia/reperfusion (I/R)‑induced AKI could improve renal function.

The mixed coupled nonlinear Schrödinger equation on the half-line via the Fokas method.

In this paper, we implement the Fokas method to study initial-boundary value problems of the mixed coupled nonlinear Schrödinger equation formulated on the half-line with Lax pairs involving 3×3 matrices. The solution can be written in terms of the solution to a 3×3 Riemann-Hilbert problem. The relevant jump matrices are explicitly expressed in terms of the matrix-value spectral functions () and (), which are determined by the initial values and boundary values at =0, respectively.

Transplantation of induced pluripotent stem cell-derived renal stem cells improved acute kidney injury.

Background: Acute kidney injury (AKI) is a severe disease with high morbidity and mortality. Methods that promote repair of the injured kidney have been extensively investigated. Cell-based therapy with mesenchymal stem cells or renal progenitor cells (RPCs) resident in the kidney has appeared to be an effective strategy for the treatment of AKI.

MicroRNA-195 promotes apoptosis in mouse podocytes via enhanced caspase activity driven by BCL2 insufficiency.

Background: The apoptosis of podocytes is a characteristic event in diabetic nephropathy. The aim of this study was to investigate whether microRNAs (miRNAs) affect podocyte apoptosis in diabetic circumstances.

Methods: Diabetic nephropathy was induced in DBA/2 mice by intraperitoneal injections of streptozotocin, and the levels of proteinuria were measured with ELISA.

Effect of Equiguard in treating patients with Shen-yang deficiency syndrome.

Objective: To observe the therapeutic effect of Equiguard in old patients with Shen-yang deficiency syndrome (SYDS).

Methods: Twenty old patients with diagnosis matching the criteria of SYDS selected from out-patients were administered with Equiguard capsule 3 times per day, 0.70 g each time for 3 successive months.
