Leiomyosarcomas (LMSs) are malignant tumors of smooth muscles accounting for 5-6% of all soft tissue sarcomas. They are mostly seen in the gastrointestinal tractus, the uterus, and the retroperitoneum. Soft tissue sarcomas comprise <1% of all laryngeal malignancies, most of which are chondrosarcomas. Laryngeal LMSs are rarely seen malignancies, which are published as case reports. We presented a case of laryngeal LMS, which was seen 4 years later in a laryngeal squamous cell carcinoma patient who underwent laryngeal laser microsurgery. We discussed the diagnosis and treatment algorithm in the light of the present literature.

Buruli ulcer (BU) is a necrotizing skin and soft tissue disease caused by Mycobacterium ulcerans that is common in hot and humid climates. Mycobacterium ulcerans is a nontuberculous mycobacterium and ubiquitous acid-fast gram-positive bacillus known to thrive in aquatic environments and water insects. The mode of transmission to humans is poorly understood and varies by geography.

Purpose: The positron range effect can impair PET image quality of Gallium-68 (Ga). A positron range correction (PRC) can be applied to reduce this effect. In this study, the effect of a tissue-independent PRC for Ga was investigated on patient data.

Epstein-Barr virus-associated smooth muscle tumors (EBV-SMTs) represent a rare category of soft tissue tumors that are predominantly seen in individuals with compromised immune systems. Pathologically, EBV-SMT has malignant potential because of its unpredictable nature. These tumors can manifest at various anatomical sites or even multiple lesions in different locations.

Hydrogel-based sensors typically demonstrate conspicuous swelling behavior in aqueous environments, which can severely compromise the mechanical integrity and distort sensing signals, thereby considerably constraining their widespread applicability. Drawing inspiration from the multilevel heterogeneous structures in biological tissues, an antiswelling hydrogel sensor endowed with high strength, rapid self-recovery, and low swelling ratio was fabricated through a water-induced phase separation and coordination cross-linking strategy. A dense heterogeneous architecture was developed by the integration of "rigid" quadridentate carboxyl-Zr coordination bonds and "soft" hydrophobic unit-rich regions featuring π-π stacking and cation-π interactions into the hydrogels.

Patterning soft materials with cell adhesion motifs can be used to emulate the structures found in natural tissues. While patterning in tissue is driven by cellular assembly, patterning soft materials in the laboratory most often involves light-mediated chemical reactions to spatially control the presentation of cell binding sites. Here we present hydrogels that are formed with two responsive crosslinkers-an anthracene-maleimide adduct and a disulfide linkage-thereby allowing simultaneous or sequential patterning using force and UV light.
