Background: This study aimed to examine whether the combination of low-dose ketamine and propofol in deep sedation is clinically useful in controlling the behavior in intellectually disabled patients who are typically extremely noncooperative during dental procedures. Methods: A total of 107 extremely noncooperative intellectually disabled adult patients were analyzed. In all patients, deep sedation was performed using either propofol alone (group P) or using a combination of propofol and 0.2 mg/kg or 0.4 mg/kg ketamine (groups PK0.2 and PK0.4, respectively). The procedures were performed in the order of insertion of nasal cannula into the nostril, attachment of mouth gag, and mouth cleaning and scaling. The frequency of patient movement during the procedures, mean arterial pressure, heart rate, peripheral oxygen saturation, recovery time, discharge time, and postoperative nausea and vomiting were examined. Results: The three groups were significantly different only in the frequency of patient movement upon stimulation during single intravenous injection of propofol and scaling. Conclusion: For propofol deep sedation, in contrast to intravenous injection of propofol alone, prior intravenous injection of low-dose ketamine (0.4 mg/kg) is clinically useful because it neither affects recovery, nor causes side effects and can suppress patient movement and vascular pain during procedures.
Expression Analysis of an APETALA1/FRUITFULL-like Gene in Phalaenopsis sp. ‘Hatsuyuki’ (Orchidaceae)

Members of the APETALA1 (AP1)/FRUITFULL (FUL)-like gene family of MADS-box genes play important roles in controlling the development of floral organs. To understand the molecular mechanisms of floral development in orchid, we isolated and characterized a Phalaenopsis AP1/FUL-like gene, PhalFUL. The results of phylogenetic analysis indicated that PhalFUL is in the monocots group of AP1/FUL-like gene. PhalFUL transcripts were detected in the flower buds, but not in vegetative organs. Moreover, in situ hybridization experiments revealed PhalFUL hybridization signals in all floral organ primordia at a very early stage of floral development, and continued expression in the column of whorls 3 and 4 until late developmental stages. These expression patterns were similar to those of the FUL-like genes in Arabidopsis (FUL) and Antirrhinum (DEFH28), suggesting that the PhalFUL is similar in function to FUL and DEFH28.

Scintillating properties of Bi-doped $Y_3Ga_5O_{12}$

Shaped single crystals of Bi : $Y_3Ga_5O_{12}$(Bi = 0.041, 0.047 and 0.061 mol%) were grown by the micro-pulling-down method. Optical absorption spectra show an absorption band at 288 nm ascribed to the lowest energy $6s^2$ \longrightarrow 6s6p transition of $Bi^{3+}$ , while luminescence spectra demonstrate the band at 314 nm ascribed to the reverse radiative transition of the excited $Bi^{3+}$ centres. At room temperature, dominant decay time component was found to be about 440 ns with a minor slower component 580 ns.
