We report a rare case of angioleiomyoma that occurred in the intra-articular portion of the knee joint. A 43-year-old female was referred to us with a 3-year history of recurrent pain and a loss of full extension of the right knee. Physical examinations revealed swelling and restriction of active full extension. Magnetic resonance imaging (MRI) revealed an intra-articular tumor. Surgical excision was performed, and the histology was characteristic of an angioleiomyoma. The patient became asymptomatic after the operation. At 2-year follow-up after the operation, no recurrence has developed.

Wrist movements play a crucial role in upper-limb motor tasks. As prosthetic and robotic hand technologies have evolved, increasing attention has been focused on replicating the anatomy and functionality of the wrist. Closely imitating the biomechanics and movement mechanisms of human limbs is expected to enhance the overall performance of bionic robotic hands.

The spectral reflectance provides valuable information regarding vegetation growth and plays an important role in agriculture, forestry, and grassland management. In this study, a small, portable vegetation canopy reflectance (VCR) sensor that can operate throughout the day was developed. The sensor includes two optical bands at 710 nm and 870 nm, with the light separated by filters, and has a field of view of 28°.

PGLa, an antimicrobial peptide (AMP), primarily exerts its antibacterial effects by disrupting bacterial cell membrane integrity. Previous theoretical studies mainly focused on the binding mechanism of PGLa with membranes, while the mechanism of water pore formation induced by PGLa peptides, especially the role of structural flexibility in the process, remains unclear. In this study, using all-atom simulations, we investigated the entire process of membrane deformation caused by the interaction of PGLa with an anionic cell membrane composed of dimyristoylphosphatidylcholine (DMPC) and dimyristoylphosphatidylglycerol (DMPG).

Rigid, conjugated molecules are excellent candidates as molecular wires since they can achieve full extension between electrodes while maintaining conjugation. Molecular design can be used to minimize the accessible pi surface and interactions between the bridging wire and the electrode. Polyynes are archetypal molecular wires that feature a rigid molecular framework with a cross-section of a single carbon atom.

The need for standardized criteria in partner and child maltreatment response systems is critical for providing fair decisions, allocating family support, producing reliable research findings, and aiding prevention efforts, among other tasks. The primary goal of this study was to replicate Heyman and Slep's (see record 2009-23534-017) study-whether maltreatment incident determination committee decisions of local sites matched those of master reviewers. This study extended the prior work by testing if specific training techniques (i.
