Background: Dilated cardiomyopathy (DCM) is a severe heterogeneous cardiomyopathy characterized by cardiac enlargement and declining heart function, often leading to refractory heart failure and life-threatening outcomes, particularly prevalent in China. The challenge lies in the scarcity of targeted therapies with substantial efficacy for DCM. Additionally, traditional anti-heart failure drugs are constrained due to hypotension propensity or limited symptom improvement.

Quantum dots (QDs) laser has become an important way to solve micro-application problems in many fields. However, single wavelength distributed Bragg reflector (DBR) has many limitations in practical applications, such as signal transmission. How to realize multiwavelength DBR lasing output simply is a challenge.

The enhancement of photoluminescence (PL) stability of colloidal quantum dots (CQDs) is of great significance in light-emitting devices. In this work, the PL stability of CdTe CQDs under time storage, strong light irradiation, acid and alkali corrosion and low temperature freezing is analyzed, and the PL quenching mechanism in a harsh environment is analyzed. Furthermore, the PL stability is extremely improved by core-shell coating, film deposition and polymer encapsulation.

Optical modulation is the process of modifying the structure and elemental composition of materials so that the main optical parameters, including amplitude, frequency, and phase, are changed. Currently, much research attention has been directed toward ultrafast dynamics, but the process of modulation is often complex. To simplify the optical modulation process and improve the optical properties of perovskites for semiconductor quantum dot (QD) lasers, the process and physical mechanism underlying graphene QD ultrafast modulation of the optical properties of perovskite CsPbBr QDs were investigated.

Doxorubicin (Dox) is one of the most effective chemotherapy agents used in the treatment of solid tumors and hematological malignancies. However, it causes dose-related cardiotoxicity that may lead to heart failure in patients. Luteolin (Lut) is a common flavonoid that exists in many types of plants.

A number of traditional Chinese medicines (TCMs) are widely used in prostate cancer treatment in China. The aim of this study was to test the efficacy of a TCM, Zhoushi Qiling Decoction (ZQD), in combination with androgen deprivation therapy (ADT) and explore its underlying mechanism. A total of 151 patients were recruited to receive ADT treatment or ADT+ZQD treatment.

Aim: This study aimed to understand the molecular mechanism underlying the therapeutic effect of Qi Ling (QL) against androgen-independent prostate cancer.

Methods: The relative expression of TRIM66 in prostate tumor was interrogated by microarray. Real-time polymerase chain reaction and Western blotting were performed to determine the transcript abundances and protein expressions of TRIM66, HP1γ, AR, c-Myc, and GAPDH.

To understand the effects of thermal annealing on the structure of GeAsSe thin films, the thermal evolution of these films was measured by the in situ X-ray diffraction (XRD) at different temperature (773 K or 1073 K) in a vacuum (10 Pa) environment. The entire process of crystallization can be observed by using in situ XRD, which is from the appearance of a crystal structure to melting liquid-state and ultimately to the disappearance of the amorphous structure. In the crystallized process, the corresponding state-transition temperatures T (the onset crystallization temperature), T (the transition temperature from glassy-state to liquid-state), T (peak crystallization temperature) are linear with MCN (Mean Coordination Number).

Article Synopsis
  • * Results showed that the films' thickness and light transmittance were significantly affected by the preparation conditions, with the best performance observed at room temperature, 800 °C, and 10 Pa pressure.
  • * The investigation revealed that high-temperature conditions lead to improved energy transfer and lower resistivity, indicating that preparation conditions play a crucial role in determining the properties of these semiconductor chalcogenide materials.
