Bilateral symmetrical fibrous palate hyperplasia is not a common case in the literature. The cause of this pathological change is not completely known. The development of hyperplasia may also be associated with a genetic mutation in the gingival soft tissue or gingival injury. We present a case of a 47-year-old patient who developed a formation that manifested bilaterally in the hard palate. After the excision, there were no histological elements in the material that indicated aggressive behavior of the formation. The clinical and histological diagnosis was the bilateral symmetrical palate hyperplasia, which is a very rare condition.
Lithium metal anodes generally suffer from uncontrolled dendrite growth and large volume change, while traditional skeletons such as LiIn and LiSn are too heavy and discontinuous to offer highly efficient structural supportability for composite Li anodes. In this work, lightweight and stable fiber-clustered skeletons, which are composed of LiB fibers and jointed LiSi nanoparticles, can be obtained by smelting SiB powder and Li ingots. In addition to serving as both ionic and electronic conductors for composite Li anodes, the stable skeletons reduced volumetric fluctuation by offering uniform, heterogeneous, and continuous architectures while suppressing lithium dendrites with low nucleation overpotential and diffusion energy barrier.
The two most critical technical issues in Zn-based batteries, dendrite formation, and hydrogen evolution reaction, can be simultaneously addressed by introducing negatively charged fibrous ZrO as a separator. Electron redistribution between ZrO and Zn ions renders the ZrO surface a preferred adsorption site for Zn ions, making surface conduction the primary ion-transport mode. Surface conduction enables fibrous ZrO to exhibit a 6.
Background/objectives: Gynecomastia is a common condition characterized by the benign enlargement of male breast tissue, often resulting from hormonal imbalances. A rare variant, unilateral pseudogynecomastia, involves enlargement due to adipose tissue accumulation without glandular proliferation and can be associated with occupational factors.
Methods: We report the case of a 45-year-old male mechanic presenting with unilateral enlargement of the left breast.
Studying scute and fin morphology are advantageous approaches for phylogenetic identification and provide information on biological linkages and evolutionary history that are essential for deciphering the fossil record. Despite this, no prior research has precisely characterized the histological structures of scutes in the common pleco. Therefore, this research investigated the microstructure and organization of bone tissue within the dermal skeleton, including the scutes and fins, in the common pleco, using light microscopy, stereomicroscopy, and scanning electron microscopy.
