Despite their perceived inaccessibility, the marine intertidal and benthic environments of Antarctica, southern Africa and South America have continued to provide marine natural products for chemists with unique opportunities to study the... more
Non-pathogenic Bacillus species used in cleaning products produce the appropriate enzymes to degrade stains and soils. However, there is little scientific data regarding the human exposure by inhalation of Bacillus spores during or after... more
Systemic juvenile idiopathic arthritis (SJIA) is an autoinflammatory disease associated with chronic arthritis. Early diagnosis and effective therapy of SJIA is desirable, so that complications are avoided. The PRO-KIND initiative of the... more
The secondary metabolites isolated from Rubia species, their biological activities, and colouration properties have been reviewed. Over 150 chemical constituents belonging to different classes of bioactive compounds such as anthraquinones... more
Marine microbes have been a storehouse of bioactive metabolites with tremendous potential as drug candidates. Marine microorganism derived secondary metabolites (chemical compounds/peptides) are considered to be a burning area of research... more
The treatment of buccal gingival recessions is a common requirement due to aesthetic concern or root sensitivity. The aim of this manuscript was to systematically review the literature on coronally advanced flap (CAF) alone or in... more
... E-mail hyoshi{at}cardiol.med.kyushu-u.ac.jp. ... General Procedures The study was conducted with the participants in a supine position and in a postabsorptive state in an air-conditioned room at 25°C to 26°C. Under local anesthesia... more
Marine molluscs from the family Muricidae hold great potential for development as a source of therapeutically useful compounds. Traditionally known for the production of the ancient dye Tyrian purple, these molluscs also form the basis of... more
Background: Despite a large body of clinical and histological data demonstrating beneficial effects of enamel matrix proteins (EMPs) for regenerative periodontal therapy, it is less clear how the available biological data can explain the... more
A low molecular weight, alkaline-stable endoxylanase (XylB) was purified to homogeneity from solid-state culture of Aspergillus fischeri Fxn1. XylB had a molecular mass of 13 kDa which is the lowest of reported xylanases. Optimal activity... more
In the postgenomic era, information is king and information-rich technologies are critically important drivers in both fundamental biology and medicine. It is now known that single-parameter measurements provide only limited detail and... more
Chemical investigations on a sponge Haliclona sp. found a meroditerpene 1 having a new carbon skeleton. By analyzing spectroscopic data, the structure was elucidated to comprise a substituted hydroquinone, a tetrahydrooxepine, and a... more
