Infant Incubator is the most important equipment in a infant ICU. This maintain adequate temperature and humidity for survival of infants. The final object of this research is Web-based monitoring of several infant incubators in ICU. To realize these objects, we developed a temperature/humidity sensing module which is interfaced to Web server board via RS485 port. We used a small micro controller in each sensing module. So the size of this module is small enough to be attached to incubator. We can access each sensing module with RS485 port on Web server board via network. As a first trial, we networked 4 infant incubators. The operator can send alarms to each incubator and these alarms are indicated with sounds and lights on measurement module. Our system can increase the convenience by a intensive central monitoring, so instant handling to some kinds of accident is possible.

Background: Transporting preterm neonates soon after birth entails risks. Only one study among many about the beneficial effects of Kangaroo Mother Care (KMC) had cited it as a safe and effective alternative to transport incubators. Objective: To determine if KMC transport could be an alternative to transport incubators by comparing the physiological outcomes of the two transport methods. Methods: This is a parallel non-blinded randomized-controlled trial funded by KMC Foundation, Philippines, Inc, of physiologically stable preterm neonates weighing ≤ 2200 grams delivered at a tertiary government hospital from September 10, 2011, to April 18, 2012. After obtaining written consent from their mothers, participants were randomly assigned to either the intervention or control group. The intervention groups were transported from the delivery room to the NICU while on skin-to-skin contact with the caregiver. In contrast, those in the control group were placed in a transport incubator. Vital signs, oxygen saturation, and blood glucose were measured before transport and upon NICU arrival. Adverse effects were monitored. Data were recorded using a standard database. Results: Ninety-two participants were recruited, forty-six in each arm. Two dropped out. The mean change in heart rate in the KMC transport decreased by 1.6 beats per minute; respiratory rate decreased by 0.18 breaths per minute, the temperature increased by 0.01°C, oxygen saturation decreased by 0.07%, blood glucose decreased by 5.07 mg/dL. The measured physiological parameters were not statistically significant between the two groups. In the KMC transport, there was a decreasing trend in the incidence of hypothermia, hypoglycemia, tachypnea, and tachycardia. Conclusion There are no significant differences in the heart rate, respiratory rate, temperature, oxygen saturation, and blood glucose levels among preterm neonates on KMC transport compared with preterm neonates on transport incubators, which is the current standard of care. The study showed that KMC transport is equally effective as a transport incubator. Hence, in low-resource settings, KMC transport may be used as a safe and effective neonatal transport.

PURPOSE: Epileptic patients have a increasing tendency to develop seizure attack in high temperature. This finding suggests that high temperature may have an effect on neuronal hyperexcitability and injury of epileptic brain. Therefore, the influence of high temperature on normal and epileptic brain was studied in organotypic explant cultures of rat. METHODS: Fourteen days-in-vitro cultures from 8 day-old rat pups were perfused with standard aCSF bubbled with 95%/5% O2/CO2 in a microchamber. Stimulus train(0.3 sec, 60 Hz) was applied to Schaffer collaterals in CA3 and extracellular field potential was recorded in the CA1 pyramidal layer. At 36degrees C initially, AD was evoked. In high temperature(HT) group, the cultures were subjected to 39degrees C for a period of 8 min before the second stimulus train was applied. They were then restored to 36degrees C for 10 min. In normal temperature group, temperature was maintained at 36degrees C for the second stimulus train. The cultures were returned to the incubator and observed serially for neuronal damage. Intensity of propidium iodide fluorescence indicative of neuronal injury was quantitated by digital image analysis. The cultures on the same insert that were not stimulated served as the unstimulated groups. RESULTS: There was not a statistically significant difference in neuronal damage between the unstimulated high-temperature(HT) and normal-temperature(NT) group. In CA1 sector, % damage(mean+/-SEM) was 0.42+/-0.20 vs 0.27+/-0.05 at 24 hrs(HT vs NT group, n=16 each, P>0.05, Student t-test); 1.81+/-0.79 vs 1.43+/-0.27 at 48 hrs(P>0.05); 3.50+/-1.32 vs 3.35+/-0.56 at 72 hrs(P>0.05). In CA3 sector, % damage was 0.34+/-0.10 vs 0.20+/-0.03 at 24 hrs(P>0.05); 0.99+/-0.20 vs 0.83+/-0.23 at 48 hrs(P>0.05); 2.00+/-0.38% vs 2.26+/-0.35% at 72 hrs(P>0.05). Neuronal damage on AD induced cultures during febrile setting(n=16) was significantly higher than in nonfebrile setting(n=16). In CA1 sector, % damage was 6.63+/-2.56 vs 0.92+/-0.45 at 24 hrs(febrile setting vs nonfebrile setting, P= 0.036); 26.37+/-7.44 vs 4.99+/-2.23 at 48 hrs(P=0.010); 38.59+/-9.63 vs 6.48+/-2.30 at 72 hrs (P=0.003). In CA3 sector, % damage was 1.23+/-0.48 vs 3.91+/-2.37 at 24 hrs(P=0.277); 13.09+/-5.75 vs 5.93+/-3.27 at 48 hrs(P=0.288); 27.86+/-8.68 vs 7.54+/-3.74 at 72 hrs(P=0.04). CONCLUSION: At high temperature, seizures in epileptic brain may be more injurious than seizures in normal temperature.

OBJECTIVES: To investigate the effects of KCl on regulation of circadian gene CLOCK expression, we observed whether induction of CLOCK is influenced by KCl depolarization in B35 rat neuroblastoma cells. METHODS: B35 rat neuroblastoma cells were grown in Dulbecco's modified Eagle's medium supplemented with 10% FBS and 1% penicillin-streptomycin in a 37 degrees C humidified incubator with 5% CO2. Inhibitors including cycloheximide and actinomycin D were pretreated 1 hour before treatment with 50mM KCl. Immunoblotting with anti-CLOCK antibody was done. RESULTS: CLCOK is induced by 50 mM KCl in B35 Rat Neuroblastoma cells, and a maximal induction in CLOCK level reached peak at 8 to 20 hours. The pretreatment of cycloheximide and actinomycin D prevented the induction of CLOCK by 50 mM KCl. CONCLUSION: We suggest that KCl depolarization may play critical roles in several aspects of the circadian gene CLOCK expression.

PURPOSE: Maxillofacial silicone elastomer is usually colored intrinsically with color pigments to match skin colors. The purpose of this study was to investigate the color stability of a maxillofacial silicone elastomer, colored with a thermochromic, color changing pigment. MATERIALS AND METHODS: Disc-shaped maxillofacial silicone specimens were prepared and divided into 3 groups: a conventionally colored control group, one group additionally colored with 0.2 wt% thermochromic pigment , and one group with 0.6 wt% thermochromic pigment. Half of the surface of each specimen was covered with an aluminium foil. All of the specimens were exposed to UV radiation in 6 hour cycles over 46 days. In between the UV exposures, half of the specimens were stored in darkness, at room temperature, and the other half was stored in an incubator, at a humidity of 97% and a temperature of +37degrees C. Color measurements were made with a spectrophotometer and registered according to the CIELAB L*a*b* color model system. The changes in L*, a* and b* values during artificial aging were statistically analyzed by using paired samples t-test and repeated measures ANOVA. P-values <.05 were considered as statistically significant. RESULTS: The UV exposure resulted in visually noticeable and statistically significant color changes in the L*, a* and b* values in both of the test groups containing thermochromic pigment. Storage in the incubator lead to statistically significant color changes in the a* and b* values of the specimens containing thermochromic pigment, compared to those stored at room temperature. CONCLUSION: The specimens containing thermochromic pigment were very sensitive to UV radiation, and the thermochromic pigment is not suitable, as such, to be used in maxillofacial prostheses.

PURPOSE: To evaluate the air contamination of the gelfoam in the angio-intervention room. MATERIALS AND METHODS: After exposing four groups of gelfoam(group A1 : gelfoam fragment, group A2 : gelfoam fragment+ saline +contrast media, group B1 : gelfoam powder, group B2 : gelfoam powder + saline + contrast media) to air in the angio-intervention room, we inoculated gelfoam in each group to 30 agar plates each at every fifteen minutes for one hour with aseptic cotton buds. Cultivating them in the incubator for one day, we evaluated the growth of bacteria or fungus. RESULTS: Out of 480 inoculated agar plates, the growth of coagulase(-) staphylococci was visible in 14 ; in group A1, two at 30 minutes, three at 45 minutes, and four at 60 minutes ; in group A2, one at 45 minutes and two at 60 minutes ; in group B1 and B2, one each at 45 minutes. The stastical analysis on bacterial contamination according to time sequence and group revealed no significance(p<0.05). CONCLUSIONS: If gelfoam is exposed to room air for less than 30 minutes, it is possible to reduce contamination by air-borne bacteria. Since coagulase-negative Staphylococci resistant to commonly used antibiotics, it is ideal to reduce exposure of gelfoamto room air for less than 30 minutes.
