    S-ECC plaques had more active interaction with cariogenic carbohydrates like sucrose and lactose than healthy plaques. We supported lactose has less cariogenicity compared with sucrose from microbial community structural aspect. Phenylalanine may have a potentially inhibitory effect on caries development.

    Periodontopathic bacteria

    in humans and

    in animals are phylogenetically close and commonly have FimA and Mfa1 fimbriae. However, little is known about how

    and

    are phylogenetically different between

    and

    . Here, we examined phylogenetic diversity in their

    and

    gene clusters.

    Twenty

    strains were isolated from the periodontal pocket of 20 dogs. For their genomic information, along with 64

    and 11

    genomes, phylogenetic relationship between the genotypes of

    and

    was examined. Variability of amino acid sequences was examined in the three-dimensional structure of FimA. The distance between strains was calculated for

    and

    genes.

    Some

    genotypes in

    were close to particular types in

    . Two types of

    were classified as 70-kDa and 53-kDa protein-coding

    . The variable amino acid positions were primarily at the outer part of FimA. The genes encoding the structural proteins and the main component were similarly distant from the reference strain in

    , but not in

    .

    The differences in the gene clusters between

    and

    may result in their host specificity.

    The differences in the gene clusters between P. gingivalis and P. MD-224 cell line gulae may result in their host specificity.

    Osteochondral defects (OCDs) of the shoulder represent a typical clinical problem and are difficult to manage. OCDs of the upper extremity are less common than those of the lower extremity. The incidence is reported to be between 5-17% in which the humerus is affected more frequently than the glenoid. OCD is often accompanied with symptoms and may appear secondary to trauma, instability or prior operation. The problem of the lesions is the missing blood circulation which makes the healing impossible. The hazard of OCDs is the progression to osteoarthritis. In spite of the effectiveness of total shoulder arthroplasty it is not the first option for young and active patients. The therapy options of OCD depend on the size and localization of the defect.

    The aim of this multimedia article is to reveal a therapy option for OCDs of the glenoid.

    In this case we present the reconstruction of a central full-thickness osteochondral glenoid defect with an osteochondral autograft from the ipsilateral knee which was withdrawn using the OATS-Technique (Arthrex, Naples, Florida) to address the chondral as well as the osseous pathology. To the best of our knowledge there has been no such procedure performed and described so far.

    The procedure lead to proper restoration of the defect.

    The demonstrated technique can be used to perform the reconstruction of a full-thickness osteochondral glenoid defect.

VU6027459 displayed CNS penetration in both mice (Kp = 2.74) and rats (Kp= 4.78), it was orally bioavailable in rats (%F = 69.5), and undesired activity at DAT was ablated.Efforts aimed at increasing the in vivo potency and reducing the elimination half-life of 1 and 2 led to the identification of aryl ether and thioether-derived bicyclic S1P1 differentiated modulators 3-6. The effects of analogs 3-6 on lymphocyte reduction in the rat (desired pharmacology) along with pulmonary- and cardiovascular-related effects (undesired pharmacology) are described. Optimization of the overall properties in the aryl ether series yielded 3d, and the predicted margin of safety against the cardiovascular effects of 3d would be large enough for human studies. Importantly, compared to 1 and 2, compound 3d had a better profile in both potency (ED50 less then 0.05 mg/kg) and predicted human half-life (t1/2 ∼ 5 days).Galectin-3 has been identified as a critical player in driving the neuroinflammatory responses in Alzheimer’s disease (AD). A key feature of this function of galectin-3 is associated with its interaction with the triggering receptor expressed on myeloid cells-2 (TREM2). Herein, we report a high-throughput screening (HTS) platform that can be used for the identification of inhibitors of TREM2 and galectin-3 interaction. We have utilized this HTS assay to screen a focused library of compounds optimized for the central nervous system (CNS)-related diseases. MG-257 was identified from this screen as the first example of a small molecule that can attenuate TREM2 signaling based on its high affinity to galectin-3 (endogenous ligand of TREM2). Remarkably, MG-257 reduced the levels of proinflammatory cytokines in activated microglial cells, which highlights its ability to inhibit the neuroinflammatory response associated with AD.The toll-like receptor (TLR) family is an evolutionarily conserved component of the innate immune system, responsible for the early detection of foreign or endogenous threat signals. In the context of autoimmunity, the unintended recognition of self-motifs as foreign promotes initiation or propagation of disease. Overactivation of TLR7 and TLR9 have been implicated as factors contributing to autoimmune disorders such as psoriasis, arthritis, and lupus. In our search for small molecule antagonists of TLR7/9, 7f was identified as possessing excellent on-target potency for human TLR7/9 as well as for TLR8, with selectivity against other representative TLR family members. Good pharmacokinetic properties and a relatively balanced potency against TLR7 and TLR9 in mouse systems (systems which lack functional TLR8) made this an excellent in vivo tool compound, and efficacy from oral dosing in preclinical models of autoimmune disease was demonstrated.
