Ameliorative effects of a Chinese herbal formula, fufang meidengmu on uterine leiomyoma in a mice model.

Fufang Meidengmu (FFMDM) is an ethnic herbal medicine form Yunnan province of China, which is often used for the treatment of uterine leiomyoma (UL). Combined Gancao (Glycyrrhiza uralensis Fisch.) and Haizao (Sargassum pallidum (Turn.

Efficient Mesh Interface Engineering: Insights from Bubble Dynamics in Electrocatalysis.

Electrochemical catalysis offers great potential in energy and mass conversion in academy and industry. However, bubble dynamics and its influence on gas-evolving electrode systems remain ambiguous. Detailed information on the local transport process between different phases and the underlying mechanism are required for the full understanding of two-phase flow evolution and distribution.

Controllable Preparation of Ordered and Hierarchically Buckled Structures for Inflatable Tumor Ablation, Volumetric Strain Sensor, and Communication via Inflatable Antenna.

Inflatable conducting devices providing improved properties and functionalities are needed for diverse applications. However, the difficult part in making high-performance inflatable devices is the enabling of two-dimensional (2D) buckles with controlled structures on inflatable catheters. Here, we report the fabrication of highly inflatable devices with controllable structures by wrapping the super-aligned carbon nanotube sheet (SACNS) on the pre-inflated catheter.

Electric-field control of ferromagnetism through oxygen ion gating.

Electric-field-driven oxygen ion evolution in the metal/oxide heterostructures emerges as an effective approach to achieve the electric-field control of ferromagnetism. However, the involved redox reaction of the metal layer typically requires extended operation time and elevated temperature condition, which greatly hinders its practical applications. Here, we achieve reversible sub-millisecond and room-temperature electric-field control of ferromagnetism in the Co layer of a Co/SrCoO system accompanied by bipolar resistance switching.

(±)-Homocrepidine A, a Pair of Anti-inflammatory Enantiomeric Octahydroindolizine Alkaloid Dimers from Dendrobium crepidatum.

A pair of racemic indolizidine enantiomers, (±)-homocrepidine A (1), and a piperidine derivative, homocrepidine B (2), were isolated from Dendrobium crepidatum along with the known alkaloid crepidine (3). The racemic mixture of 1 was separated into a pair of enantiomers, (+)-1 and (-)-1, by HPLC using a chiral chromatographic substrate, which represents the first successful example of resolving indolizidine racemic mixtures. The absolute configurations of (+)-1 and (-)-1 were assigned from single-crystal X-ray diffraction data.

A new triterpenoid bearing octacosanoate from the stems and roots of Clerodendrum philippinum var. simplex (Verbenaceae).

A new triterpenoid bearing octacosanoate, named taraxer-3β-yl octacosanoate (1), together with 13 known compounds (2-14), was isolated from the ethanol extract of the stems and roots of Clerodendrum philippinum var. simplex. The structure of taraxer-3β-yl octacosanoate (1) was elucidated by extensive spectroscopic analysis.

Uncarilic acid and secouncarilic acid, two new triterpenoids from Uucaria sessilifructus.

Two new compounds, the 6-oxo oleanane-type triterpenoid uncarilic acid, and its 5,6-secotriterpenoid derivative, secouncarilic acid, were isolated from the hooks and stems of Uucaria sessilifructus together with seven known ursane-type triterpenoids. Uncarilic acid is the second 6-oxo oleanane-type triterpenoid ever reported, while secouncarilic acid is the first oleanane-type 5,6-secotriterpenoid. A plausible biosynthetic pathway from uncarilic acid to secouncarilic acid was also postulated.
