Rapid auditory learning of temporal gap detection.

The rapid initial phase of training-induced improvement has been shown to reflect a genuine sensory change in perception. Several features of early and rapid learning, such as generalization and stability, remain to be characterized. The present study demonstrated that learning effects from brief training on a temporal gap detection task using spectrally similar narrowband noise markers defining the gap (within-channel task), transfer across ears, however, not across spectrally dissimilar markers (between-channel task).

Evaluation of the efficacy of titanium plates as denture markers under various heat sources and pressure - An in vitro study.

Introduction: Denture Markers are used as one of the main identifying aid in mass disasters. Dental description of missing person in mass disasters plays a vital role in forensic research. Difficulties arise when the teeth are missing.

Anti-psoriatic activity of Givotia rottleriformis in rats.

Objectives: To evaluate the antipsoriatic activity of Givotia rottleriformis bark in rats.

Materials And Methods: The antipsoriatic activity of the ethanol extract was investigated using ultraviolet B (UV-B)-induced photodermatitis model in rats. The animals were divided into four groups (6/groups).

Enhanced auditory temporal gap detection in listeners with musical training.

Many features of auditory perception are positively altered in musicians. Traditionally auditory mechanisms in musicians are investigated using the Western-classical musician model. The objective of the present study was to adopt an alternative model-Indian-classical music-to further investigate auditory temporal processing in musicians.

Dimensions and determinants of trust in health care in resource poor settings--a qualitative exploration.

Background: Trust in health care has been intensely researched in resource rich settings. Some studies in resource poor settings suggest that the dimensions and determinants of trust are likely to be different.

Objectives: This study was done as a qualitative exploration of the dimensions and determinants of trust in health care in Tamil Nadu, a state in south India to assess the differences from dimensions and determinants in resource rich settings.

Gold and silver nanoparticles from Trianthema decandra: synthesis, characterization, and antimicrobial properties.

Background: There is an increasing commercial demand for nanoparticles due to their wide applicability in various markets, including medicine, catalysis, electronics, chemistry, and energy. In this report, a simple and ecofriendly chemical reaction for the synthesis of gold and silver nanoparticles from Trianthema decandra (Aizoaceae) has been developed.

Methods And Results: On treatment of aqueous solutions containing chloroauric acid or silver nitrate with root extract of T.

Evaluation of Dot-ELISA and enzyme-linked immuno-electrotransfer blot assays for detection of a urinary hydatid antigen in the diagnosis of cystic echinococcosis.

Background: Several serological assays are used for detection of a hydatid antigen in serum for diagnosis of cystic echinococcosis (CE). However, it requires technical expertise and is associated with the risk of acquiring blood-borne infections. Of late, interests have been shifted to other body fluids like urine, saliva, tear drops as alternate specimens in the diagnosis of CE.

Comparative evaluation of propolis and triantibiotic mixture as an intracanal medicament against Enterococcus faecalis.

Introduction: The aim of this study was to evaluate and compare the antimicrobial activity of calcium hydroxide, triantibiotic mixture (TAM), and an ethanol extract of propolis as intracanal medicaments on Enterococcus faecalis-infected root canals.

Methods: One hundred twenty extracted intact human permanent incisors were decoronated, and chemomechanical preparation of the root canal was performed. After sterilization of the samples, they were inoculated with pure culture of E.

HDAC4 represses matrix metalloproteinase-13 transcription in osteoblastic cells, and parathyroid hormone controls this repression.

Parathyroid hormone (PTH) is a hormone regulating bone remodeling through its actions on both bone formation and bone resorption. Previously we reported that PTH induces matrix metalloproteinase-13 (MMP-13) transcription in osteoblastic cells. Here, we show that histone deacetylase 4 (HDAC4) interacts with Runx2, binds the MMP-13 promoter, and suppresses MMP-13 gene transcription in the rat osteoblastic cell line, UMR 106-01.
