Article Synopsis
  • The study aimed to assess the impact of Kuanxiong Aerosol (KXA) on coronary microcirculation in patients with unstable angina undergoing elective percutaneous coronary intervention (PCI).
  • Patients were divided into a trial group receiving KXA and a control group, with evaluations of coronary microcirculation resistance (IMR) and cardiac markers both before and after the procedure.
  • Results showed that the trial group had a significantly lower IMR after PCI, suggesting KXA may improve coronary microvascular dysfunction, although differences in myocardial injury rates were not statistically significant.

Department of Wood Anatomy and Utilization, Research Institute of Wood Industry, Chinese Academy of Forestry, Beijing 100091, China; Wood Specimen Resource Center (WOODPEDIA) of National Forestry and Grassland Administration, Beijing 100091, China. Electronic address:

Article Synopsis
  • Understanding the changes in cell wall components during xylem differentiation is crucial for grasping the structure of wood, especially at the secondary cell wall layer level.
  • In the study of Pinus bungeana, it was found that crystalline cellulose and glucomannan were deposited before xylan and lignin, with lignification starting in the primary cell wall corners as the S layer developed.
  • Immunofluorescence results showed that glucomannan was deposited earlier than xylan, and while pectins were concentrated in the primary walls, they decreased as tracheid walls differentiated, with ray cells lagging behind axial tracheids in their development.

Department of Anorectal, Xiyuan Hospital, Chinese Academy of Traditional Chinese Medicine, Beijing 100091, China.

Colorectal cancer is a malignant tumor with the third and second highest incidence and mortality rates worldwide, and its mortality rate is increasing annually. Colorectal cancer evolves gradually over a long period of time. The evolving process from colorectal adenoma to colorectal cancer takes approximately 10-15 years, providing a sufficiently long "window period" for early screening and diagnosis of colorectal cancer.

To achieve "carbon peaking and carbon neutrality", reasonable burden-sharing for emission reductions among key players is critical. And reasonable burden-sharing requires scientific clarification of their actual emissions and responsibilities, and full accounting of efforts to reduce emissions. Therefore, this paper focuses on China's power industry and proposes a burden-sharing model that reflects regions' embodied carbon emissions and mitigation efforts.

Open-window MSR Design with Active Magnetic Compensation Coil based on COMSOL Multiphysics.

Biomed Phys Eng Express

November 2024

Beihang University, 37 Xueyuan Road, Haidian District, Beijing, P.R. China, 100191., Beijing, Beijing, 100091, CHINA.

Magnetic shielding room (MSR) is one of the necessary equipment for measuring magnetocardiography (MCG) and magnetoencephalography (MEG). The traditional closed MSR only focuses on the indicators of the shielded magnetic field, and ignores the patient's feelings within the MSR. In this paper, an open-window MSR is proposed to solve the problem that patients have difficulty in communicating with the outside of closed MSR and have closed fear.

  • Diabetes mellitus (DM) is a condition marked by high blood sugar levels due to inadequate insulin production, requiring patients to undergo long-term treatment with existing hypoglycemic drugs, which are often ineffective for managing the disease.
  • Traditional weight loss surgeries, like gastric bypass, have strict BMI requirements and can lead to complications such as hypoglycemia and dumping syndrome, reducing their effectiveness for DM treatment.
  • Jejunoileostomy is a newer surgical option showing promise for improving glucose and lipid metabolism without altering the gastrointestinal structure, resulting in fewer complications and better management of DM-related issues, supported by clinical consensus on its surgical and postoperative management.

Key Laboratory of Tree Breeding and Cultivation of State Forestry Administration, Research Institute of Forestry, Chinese Academy of Forestry, Beijing 100091, China. Electronic address:

As a short-rotation woody plant, Salix viminalis has the potential for phytoremediation of cadmium (Cd), but it has poor tolerance to high Cd concentrations. Melatonin (MEL), a candidate bio-promoter, was considered to play an active role in plant responses to Cd. However, the molecular mechanism by which MEL regulates metabolic processes in plants to defend against Cd stress remain unclear.

Ensuring driving operational safety in emergency scenarios is paramount for autonomous vehicles to prevent accidents, particularly when vehicle motion completely depends on autonomous systems. Numerous factors must be evaluated when designing emergency collision avoidance strategies for critical situations, such as trajectory feasibility, vehicle motion stability, and driver comfort. Therefore, this study proposes a framework for emergency operation that uses collision-free area calculations to inform maneuver decisions and facilitate collision avoidance trajectory planning, preventing vehicle collisions.

Walnut (Juglans regia), an important contributor to oil production among woody plants, encounters research constraints due to difficulties in the subcellular localization and functional analysis of its proteins. These limitations arise from the protracted fruiting cycle and the absence of a reliable transient gene transformation system and organelle markers. In this study, we established a transient expression system using walnut protoplasts and generated fluorescent-tagged organelle markers, whose localization was validated against Arabidopsis (Arabidopsis thaliana) organelle markers.
