the osseous bonding between the bone and implant was similar in both groups, although the osseointegration surface was slightly greater in the delayed implant group [7]. In this study, we also found the adjacent BMD following the immediate implant was slightly lower, although not significantly, than that following the delayed implant. Imaging techniques to evaluate BMD non-invasively are currently... -

of the secondary bonding force that holds the polymer chains together results in a binding force larger than that in the amorphous region. 34 Thus, the surface hardness may increase with transformation of the amor- phous regions into crystalline regions. To determine the feasibility for using the thermoplas- tic materials as TOAs in clinical applications, we per- formed the three-point bending... Objective: The aim of this systematic multiscale analysis was to evaluate the effects of thermoforming on the physical and mechanical properties of thermoplastic materials used to fabricate transparent orthodontic aligners (TOAs). Methods: Specimens were fabricated using four types of thermoplastic materials with different thicknesses under a thermal vacuum. Transparency, water absorption and solubility, surface hardness, and the results of three-point bending and tensile tests were evaluated... -

The lingual multibracket appliance affords maximum esthetics with the physica] properties of a fixed metal bracket system.5) A CASE REPORT Patient M. S. Lee, a 19 year old female ，presented, with skeletal Class I pattern, crowded anterior teeth in both... reduced because of advances in lingual bracket systems, improved indirect bonding technique and the development of more flexible wires. There has been a marked increase in the number of adults desiring orthodontic treatment over recent years and many of these patients tend to seek invisible orthodontic appliances due to esthetic reasons. Although the lingual multibracket treatment is not ideal, this form of treatment is currently the best option for the patients with esthetic concerns. Here, I... -

a hydrogen bonding donor group at the cyan regions around C2-H in 1,3-propandiol, ortho hydrogen of ph enyl ring, and C1-H of alkyl chain. The CoMSIA contour map in leukemic cancer HL-60 cells (Fig. 3B) showed a sterically favorable green region at the alkyl chain from C2 to C6, where bulky groups were likely to increase the cytotoxic activity. But the bulky substituent at C1-H, C2-H, and... B13, a ceramide analogue, is a ceramidase inhibitor and induces apoptosis to give potent anticancer activity. A series of thiourea B13 analogues was evaluated for their in vitro cytotoxic activities against human renal cancer Caki-2 and leukemic cancer HL-60 in the MTT assay. Some compounds (12, 15, and 16) showed stronger cytotoxicity than B13 and C6-ceramide against both tumor cell lines, and compound (12) gave the most potent activity with IC50 values of 36 and 9</SUB>ՌM,... -

Cerebellar Purkinje cells (PCs) play a crucial role in motor functions and their progressive degeneration is closely associated with spinocerebellar ataxias. Although immunohistochemical (IHC) analysis can provide a valuable tool for understanding the pathophysiology of PC disorders, the method validation of IHC analysis with cerebellar tissue specimens is unclear. Here we present an optimized and validated IHC method using antibodies to calbindin D28k, a specific PC marker in the cerebellum. To...
