First Report of Leaf Blight Caused by on in China.

Phedimus aizoon is native to east Asian countries that including China, Siberia, Korea, Mongolia, and Japan. In China, the plant is highly valued for use in folk medicine, for detoxification and analgesia, blood pressure, hemostasis, and used as an ornamental. In August 2021, a leaf spot and blight disease were observed on P.

(Nakai et Kitagawa) Nakai et Kitagawa is one of the sources of Chinese herb "Gao-Ben". It is widely distributed in the Northeastern China. has antipyretic, antibacterial and anti-inflammatory effects (Zhang et al.

First report of causing leaf blight on in China.

In July 2019, leaf blight on Actaea dahurica, a plant with high value in Chinese traditional medicine, was discovered in a 2 ha planting area in Heilongjiang Province (129.6°E, 44.6°N), China.

Rapid Fabrication of Biocomposites by Encapsulating Enzymes into Zn-MOF-74 via a Mild Water-Based Approach.

A zinc-based metal organic framework, Zn-MOF-74, which has a unique one-dimensional (1D) channel and nanoscale aperture size, was rapidly obtained in 10 min using a mild water-based system at room temperature, which is an example of green and sustainable chemistry. First, catalase (CAT) enzyme was encapsulated into Zn-MOF-74 (denoted as CAT@Zn-MOF-74), and comparative assays of biocatalysis, size-selective protection, and framework-confined effects were investigated. Electron microscopy and powder X-ray diffraction were used for characterization, while electrophoresis and confocal microscopy confirmed the immobilization of CAT molecules inside the single hexagonal MOF crystals at loading of ∼15 wt %.

Distinct Effects of Ca Sparks on Cerebral Artery and Airway Smooth Muscle Cell Tone in Mice and Humans.

The effects of Ca sparks on cerebral artery smooth muscle cells (CASMCs) and airway smooth muscle cells (ASMCs) tone, as well as the underlying mechanisms, are not clear. In this investigation, we elucidated the underlying mechanisms of the distinct effects of Ca sparks on cerebral artery smooth muscle cells (CASMCs) and airway smooth muscle cells (ASMCs) tone. In CASMCs, owing to the functional loss of Ca-activated Cl (Clca) channels, Ca sparks activated large-conductance Ca-activated K channels (BKs), resulting in a decreases in tone against a spontaneous depolarization-caused high tone in the resting state.

Chloroquine Inhibits Ca(2+) Signaling in Murine CD4(+) Thymocytes.

Background/aims: Bitter-tasting chloroquine can suppress T cell activation by inhibiting Ca(2+) signaling. However, the mechanism of inhibition remains largely unclear.

Methods: In this study, CD4(+) T cells were isolated from the thymus, and the calcium content of CD4(+) thymocytes was measured using fura-2 AM and a TILL imaging system.

Involvement of large-conductance Ca2+-activated K+ channels in chloroquine-induced force alterations in pre-contracted airway smooth muscle.

The participation of large-conductance Ca2+ activated K+ channels (BKs) in chloroquine (chloro)-induced relaxation of precontracted airway smooth muscle (ASM) is currently undefined. In this study we found that iberiotoxin (IbTx, a selective inhibitor of BKs) and chloro both completely blocked spontaneous transient outward currents (STOCs) in single mouse tracheal smooth muscle cells, which suggests that chloro might block BKs. We further found that chloro inhibited Ca2+ sparks and caffeine-induced global Ca2+ increases.

Relaxant action of plumula nelumbinis extract on mouse airway smooth muscle.

The traditional herb Plumula Nelumbinis is widely used in the world because it has many biological activities, such as anti-inflammation, antioxidant, antihypertension, and butyrylcholinesterase inhibition. However, the action of Plumula Nelumbinis on airway smooth muscle (ASM) relaxation has not been investigated. A chloroform extract of Plumula Nelumbinis (CEPN) was prepared, which completely inhibited precontraction induced by high K(+) in a concentration-dependent manner in mouse tracheal rings, but it had no effect on resting tension.

Bitter tastants induce relaxation of rat thoracic aorta precontracted with high K(+).

It has been reported that bitter tastants decrease blood pressure and relax precontracted vascular smooth muscle. However, the underlying mechanisms remain unclear. The aim of the present study was to determine the mechanism underlying the vasorelaxant effect of the bitter tastants.
