Background and Aim: Various methods have been used to reduce the patient's anxiety during dental treatment. In recent years, there has been an increase in behavioral research regarding virtual reality (VR) and virtual world as it offers more immersive images and works by blocking out real-world stimuli (visual, auditory or both). This study aimed at assessing the impact of VR on working conditi...
The signal recognition particle (SRP)-mediated translocation of proteins across the RER is a GTP dependent process. Analysis of the primary amino acid sequence of one protein subunit of SRP (SRP54), as well as the alpha subunit of the SRP receptor (SR alpha), has indicated that these proteins contain predicted GTP binding sites. Several point mutations confined to the GTP binding consensus elem...
The aims of the study were, in conscious Sprague-Dawley rats, to compare the effects of stresscopin-related peptide (SRP) and urocortin (UCN) 1 on blood pressure, heart rate, and regional hemodynamics; to determine whether or not there were residual tachycardic effects of SRP or UCN1 after cardiac autonomic blockade; and to investigate a possible involvement of corticotropin releasing factor ty...
Cotranslational translocation of proteins across or into membranes is a vital process in all kingdoms of life. It requires targeting of the translating ribosome to the membrane by the signal recognition particle (SRP), an evolutionary conserved ribonucleoprotein particle. SRP recognizes signal sequences of nascent protein chains emerging from the ribosome. Subsequent binding of SRP leads to pau...
The signal recognition particle (SRP) is a universally conserved cellular machinery responsible for delivering membrane and secretory proteins to the proper cellular destination. The precise mechanism by which fidelity is achieved by the SRP pathway within the in vivo environment is yet to be understood. Previous studies have focused on the SRP pathway in isolation. Here we describe another imp...
SRP-27 (sarcoplasmic reticulum protein of 27 kDa) is a newly identified integral membrane protein constituent of the skeletal muscle SR (sarcoplasmic reticulum). We identified its primary structure from cDNA clones isolated from a mouse skeletal muscle cDNA library. ESTs (expressed sequence tags) of SRP-27 were found mainly in cDNA libraries from excitable tissues of mouse. Western blot analysi...
BACKGROUND This research report evaluates clinical changes resulting from local delivery of doxycycline hyclate (DH) or traditional scaling and root planing (SRP) in a group of patients undergoing supportive periodontal therapy (SPT). METHODS In all, 141 patients received either DH (67) or SRP (74) treatment in sites > or =5 mm on one-half of their dentition at baseline and month 4. RESULTS...
OBJECTIVE We previously showed that photoablative laser therapy followed by multiple photodynamic cycles (PAPD) after scaling/root planing (SRP) improved healing of periodontitis patients as compared with conventional SRP after 1-year follow-up. This study reports the favorable results of PAPD plus SRP in patients with chronic periodontitis at a 4-year follow-up. MATERIALS AND METHODS Twenty-...
Two GTPases in the signal recognition particle (SRP) and its receptor (SR) control the delivery of newly synthesized proteins to the endoplasmic reticulum or plasma membrane. During the protein targeting reaction, the 4.5S SRP RNA accelerates the association between the two GTPases by 400-fold. Using fluorescence resonance energy transfer, we demonstrate here that formation of a stable SRP x SR...
