The purpose of this study was to compare the safety and efficacy of micro-endoscopic discectomy (MED) and open discectomy (OD) for lubmar disc herniation (LDH). Randomised controlled trials (RCTs) comparing MED with OD for LDH were searched comprehensively in PubMed, EMBASE, the Cochrane Library. Relevant studies retrieved, data extracted and the quality of included studies were independently p...

The aim of this study was to evaluate the odontogenic potential of undifferentiated pulp cells (OD-21 cell line) through chemical stimuli in vitro. Cells were divided into uninduced cells (OD-21), induced cells (OD-21 cultured in supplemented medium/OD-21+OM) and odontoblast-like cells (MDPC-23 cell line). After 3, 7, 10 and 14 days of culture, it was evaluated: proliferation and cell viability...

A spontaneously spoken, natural Japanese discourse contains many instances of the so-called redundant interjections and of backchannel utterances. These expressions have not hitherto received much attention and few systematic analyses have been made. We show that these utterances are characterizable as discourse markers, and that they comprise a well-defined category, characterizable in a regul...

The purpose of this study was to evaluate the influence of ketoprofen on bone repair process in tibiae of rats by means of analysis of the digital optical density. Twenty Wistar rats were assigned to two groups: an untreated control group and a group treated with ketoprofen. The experimental procedures comprised the following stages: general anesthesia, preparation of a unicortical bone defect ...

AIMS The aim of this study was to evaluate the diagnostic potential of cerebrospinal fluid (CSF) and serum levels of neurocytoskeletal proteins and their ratios for the diagnosis of dementias and to assess the differences in neurocytoskeletal proteins between neurodegeneration and neuroinflammation. METHODS CSF and serum levels of neurofilament light subunits (NFL) and neurofilament heavy sub...

Open bite (OB) is a generalized term, which could incorporate subgroups that react differently to vertical correction. The objectives of the present study were to detect vertical treatment changes in incomplete bite (IB: inter-incisor overlap with no lower incisor contact with teeth or palate) and OB (no inter-incisor overlap) groups compared with a complete bite (CB: inter-incisor overlap with...
