Biopsy spec imens were obta ined dur ing endodontic surgical p rocedures pe r fo rmed on 35 patients. Histopathologic a n d histobacter iologic studies of the spec imens showed that there w a s no correlation be t ween the p resence of var ious inf lammatory cells a n d the clinical s igns a n d symptoms of the patients. Epithelium w a s found in 21 spec imens , but only nine lesions were d i a...

The first two components of this strategy require active community involvement. Community members must have access to primary health clinics where qualified health professionals with adequate tools can provide timely and accurate diagnosis and treatment. These health professionals must also ensure that mosqu i to nets a re p roper l y placed, used correctly, maintained in good repair, and broug...

Reaction of the acyclic (diamino)carbene (ADC) :C(NiPr2)2 (1) with different dihaloboranes of the type RBX2 (R = Mes, Dur; X = Cl, Br) smoothly afforded a novel class of ADC-stabilized borane adducts. For MesBBr2 however, the reaction did not stop at the adduct level, but an uncommon rearrangement process occurred, which eventually resulted in the formation of a 5-membered boracycle after elimi...

Peer review is used in most scientific disciplines to assess the value of new knowledge presented in journal submissions. Individuals well versed in the appropriate research domain evaluate the quality of ideas, empirical rigor, and overall contribution conveyed by a manuscript. In essence, they serve a gate-keeping role by helping to filter out low-quality work (Crane, 1967; de Grazia, 1963). ...

This review deals with the role of carboxylic amino acids in the proton transport activity of bacteriorhodopsin. The main focus is on the infrared data, which allow direct monitoring of the protonation/deprotonation of specific residues dur ing the proton movement in the course of the photocycle. Additional attention is paid to the potential use of carboxylic acids in proteins as internal senso...

The volatile constituents of the aerial parts of Carum montanum (Coss. et Dur.) Benth. et Hook. were analysed by GC-FID and GC-MS, and the main component was isolated and identified as nothoapiole. The antibacterial and antifungal activities of this compound and of the total oil were investigated against Gram-negative (P. aeruginosa, E. coli), Gram-positive (E. faecalis, S. aureus, S. epidermit...

Computer-aided learning (CAL), self-instructional programs provide an accessible, interactive, and flexible way of presenting curriculum material. In order to assess the effectiveness of CAL programs in dental education, a systematic review of the published literature comparing CAL with other teaching methods was performed. A systematic search of the published literature was performed. Articles...

OBJECTIVES This study reviews the evidence for the effectiveness of computer-assisted diagnosis (CAD) in cancer imaging. Diagnostic applications were studied to estimate the impact of CAD on radiologists' detection and diagnosis of cancer lesions. METHODS Online databases were searched and 48 studies from 1992 to 2010 were included: 16 with radiologists using CAD to detect lesions (CADe) and ...

background:  infections  in  neutropenic  patients  are  considered  as  major  causes  of  mortality and the emergence of drug resistance. gram positive bacterial infections are crucially important to be covered if indicated. vancomycin is active against most gram positive bacteria including methicillin resistant staphylococcus aureus (mrsa). in this study, we evaluated the appropriate utiliza...

ever, this may merely be a reflection of the extent to which the cuticle has been reabsorbed at the t ime of fixation since the cuticles of all these Lts are part ial ly reabsorbed dur ing moult ing. Also, the cuticle of the L~ of O. phyllobia appears to be structurally more complex than that of A. agrostis since it has a distinct striated basal layer (Fig. 1A, D) which is reabsorbed at a later...
