Diethyl pyrocarbonate (DEPC) has been useful in vitro as an agent relatively specific for binding to imidazole of histidine. Administered via the cisterna magna DEPC inhibits central chemosensitivity in conscious rabbits, supporting the alphastat hypothesis for central chemoreceptor function. In this study I have applied DEPC via 1 X 3 mm cottonoid pledgets to each of the three ventrolateral medulla (VLM) chemosensitive areas in glomectomized, vagotomized, paralyzed, and servo-ventilated alpha-chloralose-urethan-anesthetized cats. CO2 responses measured by integrated phrenic nerve output were evaluated before and after DEPC application. A dose of 40 mmol/l applied to the rostral chemosensitive area increased the CO2 threshold (5.3%) and significantly decreased (P less than 0.03; Wilcoxon sign rank test) the initial slope (-43%) and the maximum (-41%) of the CO2 response. No significant effects were observed with DEPC application in the intermediate or caudal areas. Treatment with 40 mmol/l hydroxylamine immediately after DEPC in the rostral area prevented the effects supporting the interpretation that imidazole was the reactant with DEPC. The results are consistent with the hypothesis that imidazole-histidine is involved in the mechanism of central chemoreception and indicate that only the rostral area utilizes a DEPC inhibitable mechanism.

The aim of the present study was to quantitatively assess changes in enamel roughness parameters before and after lingual bracket debonding. The lingual surface of 25 sound premolars extracted for orthodontic reasons was studied by 3D optical interferometric profilometry before and after debonding of lingual brackets following enamel finishing (with fine diamond) and polishing (with 12- and 20-fluted carbide burs). The roughness parameters tested were the amplitude parameters Sa and Sz, the hybrid parameter Sdr, and the functional parameters Sc and Sv. The parameter differences (after debonding-reference) were calculated, and statistical analysis was performed via a Wilcoxon signed-rank test. Statistically significantly higher values were observed in all the surface roughness parameters of enamel surfaces after finishing and polishing, with the mostly affected parameter being the Sdr. Under the conditions of the present study, the finishing and polishing instruments used after debonding of lingual noncustomized brackets created a surface texture rougher than the control in all the tested roughness parameters.

Consumers' awareness of halal cosmetics is still low. The high level of dependence on a product and the lack of consumer knowledge of cosmetic ingredients makes it difficult for consumers to switch to cosmetic products that are halal certified. Minimal education that is easily accessible regarding the halalness of a cosmetic product among the community is a problem that results in the lack of awareness of halal. This study aims to obtain information about the effect of halal education on knowledge and attitudes in the use of cosmetics. The method used in this study is an experimental design with a sample size of 30 respondents who are active users of cosmetics both labeled halal and not labeled halal. The sampling technique used was accidental sampling. Data on the knowledge and halal attitudes of respondents before and after education were obtained from filling out questionnaires which were carried out online. The data analysis technique used was the Wilcoxon Sign Rank Test using SPSS 16. The results of the respondents' research indicated that there were significant differences in their knowledge and attitudes towards the use of cosmetics before and after halal education with p value ≤ 0.05.

Application by pledget of the M1-antimuscarinic receptor agent pirenzepine (40 mM) to the rostral chemosensitive areas of the ventrolateral medulla in anesthetized, paralyzed, vagotomized, glomectomized, and servoventilated cats inhibited the slope of the integrated phrenic response to CO2 by 32.5% (P less than 0.03) and the maximum value by 21.1% (P less than 0.01). Similar application of the imidazole-histidine blocking agent diethyl pyrocarbonate (DEPC) decreased the slope by 40.3% (P less than 0.01) and the maximum value by 29.3% (P less than 0.05). Both responses confirm previous results. DEPC treatment decreased the effectiveness of subsequent pirenzepine application such that although slope and maximum were further decreased, the values were not significantly different from those after DEPC. Pirenzepine treatment prevented any subsequent DEPC inhibitory effect. The results raise the possibility that the inhibitory effects of DEPC on CO2 chemosensitivity are via muscarinic receptors and that muscarinic receptor involvement in CO2 chemosensitivity requires the presence of imidazole-histidine. Analysis by scintillation counting of successive 100-micron sections of medulla after rostral area application of [3H]pirenzepine indicated that the pirenzepine and DEPC effects are most probably within 2.0 mm of the ventral surface as measured from the midline, well away from the dorsal and ventral respiratory group neurons.
