05). Comparison of the medial olivocochlear reflex response between the 2 groups also revealed no statistically significant difference (p > 0.05).
Conclusion: Hyperandrogenism did
not seem to influence otoacoustic emission levels or the medial olivocochlear reflex response in adult female subjects.”
“Objectives. To investigate whether parameters in fetal biophysical profile (BPP) testing exhibit a diurnal rhythm and to discuss the probable factors associated with these variables.
Methods. Thirty healthy primigravid patients carrying pregnancies between 35 and 40 completed weeks were enrolled for the study. Fetal BPP AZD1208 cost testing was performed for each patient both in the early morning (08:00-10:00 am) and in the late evening (08:00-10:00 pm), and the scoring parameters were compared between morning and evening tests.
Results. BPP scores in the evening were significantly higher than that in the morning (p < 0.05). Deepest vertical amniotic
pocket measurements and fetal breathing absence in the morning mostly contributed to this variation (p < 0.001). Fetal movement counts were also significantly selleck inhibitor lower in the morning tests (p < 0.001).
Conclusions. The parameters of BPP exhibit circadian variations in healthy fetuses, which may be associated with many factors such as fetomaternal hormones. It is essential for the clinician to be aware of these changes when interpreting the results, as interventions based on false-positive results may have deleterious effects on both the mother and her fetus.”
“BACKGROUND: A biochemical oxygen demand (BOD) sensor, based on an immobilized Pseudomonas syringae in highly porous micro-cellular polymer (MCP) in combination with a dissolved oxygen electrode, has been developed for the analysis of biodegradable organic compounds in aqueous samples. MAPK inhibitor Microorganisms were immobilized in a molded MCP disk
and a wastewater sample was injected into the biocomposite disk by a flow injection system. Dissolved oxygen (DO) changes as a measure of soluble BOD was read with a DO probe placed into a flow cell carrying biocatalytically activated disk.
RESULTS: Optimal response of the MCP BOD sensor was obtained at pH 6.8 and 25 degrees C with a typical response time of 3-5 min for a 2 mm thick molded polymeric disk. The sensor showed detection linearity over the range 5-100 mg L(-1) BOD(5) (r(2) > 0.99) at a flow rate of 0.6 mL min(-1). The repeatability and reproducibility of the sensor response were found to be 3.08% and 7.77%, respectively. BOD values produced with this biosensor for various municipal and industrial wastewaters correlated well with those determined by the conventional 5-day BOD test.
