An Electron Microscopic Observation on Epithelial Attachment
Nihon Shishubyo Gakkai Kaishi (Journal of the Japanese Society of Periodontology), 1973 臨床的に正常歯肉と判定し, 光顕で病理組織的に初期歯肉炎とみとめた成人 (20歳～54歳) の辺縁歯肉を, 電子顕微鏡的に観察した。観察は上皮付着部を歯冠側から根尖側の尖端部にわたって行い, その結果次の様な所見を得た。(1) 歯肉溝中央より歯冠側のエナメル質表面には, cuticle に接して上皮細胞がわずかに存在した。cuticle と上皮細胞との間は, 電子密度の低い一層で隔てられ, 両者にはしばしば hemi-desmosome による接合をみとめた。(2) セメント質部の cuticle は, 根尖側にゆくにしたがってその厚さを減じ, 付着上皮の根尖側最尖端の上皮細胞とセメント質との接触部には cuticle をみとめなかった。(3) セメント質表面の cuticle は ...

A conserved metalloprotease mediates ecdysis in Caenorhabditis elegans [PDF]
, 2004 Molting is required for progression between larval stages in the life cycle of nematodes. We have identified four mutant alleles of a <i>Caenorhabditis elegans</i> metalloprotease gene, <i>nas-37</i>, that cause incomplete ...

Advanced Functional Materials, EarlyView.Fibrous benzenetrispeptide (BTP) hydrogels, fabricated via strain‐promoted azide‐alkyne cycloaddition (SPAAC) crosslinking, form robust, bioinert networks. These hydrogels can support 3D cell culture, where cell viability and colony growth depend on the fiber content.

Mechanoregulatory Effects of Cell‐Scale Microwells on Epithelial Cell Phenotype
Advanced Functional Materials, EarlyView.In small polycaprolactone microwells, A549 epithelial cells span well edges, in contrast to cells growing on flat substrates. Focal adhesion sites (yellow) concentrate at topographic boundaries, while cytoskeletal tension (magenta stress fibers) is transmitted to the nucleus (blue), reducing nuclear sphericity.

Advanced Functional Materials, EarlyView.Here, a biointerface membrane engineered with site‐specific interfacial properties is developed. During implantation between gingival and bone defect, the membrane creates a pro‐osteogenic microenvironment, precisely modulates cellular activities at each biointerface, and facilitates the orchestration of complex healing events, ultimately leading to ...

Novel Functional Materials via 3D Printing by Vat Photopolymerization
Advanced Functional Materials, EarlyView.This Perspective systematically analyzes strategies for incorporating functionalities into 3D‐printed materials via Vat Photopolymerization (VP). It explores the spectrum of achievable functionalities in recently reported novel materials—such as conductive, energy‐storing, biodegradable, stimuli‐responsive, self‐healing, shape‐memory, biomaterials, and

Decreased mucosal adhesion of Lactobacillus species in patients with inflammatory bowel disease
Caspian Journal of Internal Medicine, 2022 Background: Probiotic Lactobacillus spp. modulate immune response via interactions of their binding proteins with epithelial cells. We studied the presence of attachment protein-encoding genes (mub1, mub2, and mapA) in Lactobacillus strains with ...
