DEK::AFF2 fusion-associated middle ear non-keratinizing squamous cell carcinoma: A case report.

Background: Primary squamous cell carcinoma (SCC) of the middle ear is rare, with non-keratinizing basaloid types being exceptionally uncommon. Distinguishing these cancers, often caused by viral factors (, human papillomavirus or Epstein-Barr virus), or specific genetic alterations (, bromodomain-containing protein 4-nuclear protein in or gene fused with FLI chromosomal rearrangement), from other cranial conditions, is difficult. The recently identified DEK::AFF2 non-keratinizing SCC (NKSCC) is a novel subtype, fitting the World Health Organization classification of head and neck neoplasms.

Differences and mechanisms of color deterioration in three types of ready-to-eat shellfishes during storage.

Ready-to-eat (RTE) abalones, scallops and oysters were prepared through a process of cooking, drying, vacuum packaging, and high-temperature sterilization, and were subjected to accelerated storage. Upon storage, the three RTE shellfishes all showed color deterioration, as indicated by darker color, decreased L* and W* values, and increased a* value. In contrast, the color deterioration of RTE oysters was more pronounced.

Misdiagnosis of synovial sarcoma - cellular myofibroma with gene fusion: A case report.

Background: Cellular myofibroma is a rare subtype of myofibroma that was first described in 2017. Its diagnosis is often challenging because of its relative rarity, lack of known genetic abnormalities, and expression of muscle markers that can be confused with sarcomas that have myogenic differentiation. Currently, scholars have limited knowledge of this disease, and published cases are few.

Always positive covalent organic nanosheet enabling pH-independent adsorption and removal of Cr(Ⅵ).

Rapid and highly effective removal of hexavalent chromium (Cr(Ⅵ)) is extremely vital to water resources restoration and environmental protection. To overcome the pH limitation faced by most ionic absorbents, an always positive covalent organic nanosheet (CON) material was prepared and its Cr(VI) adsorption and removal capability was investigated in detail. As-prepared EB-TFB CON (TFB = 1,3,5-benzaldehyde, EB = ethidium bromide) shows strong electropositivity in the tested pH range of 1 ∼ 10, display a pH-independent Cr(VI) removal ability, and work well for Cr(VI) pollution treatment with good anti-interference capability and reusability in a wide pH range covering almost all Cr(VI)-contaminated real water samples, thus eliminating the requirement for pH adjustment.

Collagen-based scaffolds with high wet-state cyclic compressibility for potential oral application.

Soft tissue substitutes have been developed to treat gingival recessions to avoid a second surgical site. However, products of pure collagen for clinical application lack their original mechanical strengths and tend to degrade fast in vivo. In this study, a collagen-based scaffold crosslinked with oxidized sodium alginate (OSA-Col) was developed to promote mechanical properties.

Effect of phytic acid combined with lactic acid on color and texture deterioration of ready-to-eat shrimps during storage.

To retard the deterioration of texture and color of ready-to-eat (RTE) shrimps during storage, phytic acid (PA) and lactic acid (LA) were used to soak the shrimp prior to cooking. The factors affecting texture (water holding capacity, protein oxidation and degradation, and microstructure) and color (Maillard reaction and lipid oxidation) were determined separately. The free radical and copper ion content were also determined in order to investigate the regulation mechanism of phytic acid and lactic acid on the texture and color of RTE shrimps.

Effects of antioxidants of bamboo leaves on protein digestion and transport of cooked abalone muscles.

The effects of oxidation on protein digestion and transport in cooked abalone muscles were investigated using a combination of simulated digestion and everted-rat-gut-sac models for the first time. Boiling heat treatments caused protein oxidation in the abalone muscles, reflected by increases in the carbonyl group and disulfide bond contents, protein hydrophobicity and aggregation degree, as well as decreases in the free sulfhydryl group and amino acid contents. Protein oxidation significantly inhibited the degree of hydrolysis, digestion rate, and digestibility of the abalone muscles in the simulated digestion model.
