Effect of Low-pressure Carbonation on the Heat Inactivation and Cytoplasmic Acidification of Saccharomyces cerevisiae

Effect of low-pressure carbonation （LPC） on heat inactivation of Saccharomyces cerevisiae was investigated. The cell suspension was carbonated at 1 MPa and 4℃ for 15 min and subsequently heated from 51 to 61 ℃ and 5 s to 5 min （heating with LPC）. As a control experiment, cell suspension was heat-treated under atmospheric pressure without LPC （heating）. The inactivation ratio of heating at 53℃ and 55℃ for l rain with LPC was approximately 1 log order higher than heating alone. Extending heating time to 5 min did not widen the difference in the inactivation ratio between heating with LPC and heating alone at both heating temperatures. At 57℃, the difference in inactivation ratio increased from 1 to 2.5 log order with extending treatment time from 5 to 15 s. The results suggested that the enhanced inactivation effect by LPC was obtained at the higher temperature with short time treatment than the lower temperature with longer time treatment. Under fluorescence microscope observation of LPC-treated cell stained with LysoSensor probe, it seemed that LPC was hardly able to acidify the cytoplasm ofS. cerevisiae. It is considered that the ability orS. cerevisiae ceils to keep their cytoplasmic pH during LPC resulted in the inferior increase in heat inactivation ratio by LPC as compared with bacteria in the previous studies.

Determination of the High Temperature Stress Tolerances of Bread Wheat Genotypes

Thirty bread wheat genotypes were used as material during the 2014-2015 cropping season. The experimental layout was a randomized complete block design with 3 replications. The sowing rate was 500 seeds square meter. Sowing was done in plots of 6 rows （1.2 m × 5 m, spaced 20 cm apart） in Namlk Kemal University, Faculty of Agriculture, Field Crops Department experimental area. Two sowing times were performed. First sowing was made in November suggested usual （standard） and second one was made in January as delayed sown in order to push growing stages of plants into periods in which heat stress is expected will be effected. Sowing times were allotted to main-plots while genotypes were allotted to sub-plots. When the bread wheat varieties and lines used in the experiment are evaluated in terms of tolerance to high temperature, it was shown that Dropia and Nota varieties and CIMMYT-HTN 2014/15-2, CIMMYT-HTN 2014/15 -6, CIMMYT-HTN 2014/15 - 10 lines were better tolerance to high temperature. However, it was noticed that these genotypes were not included in the first groups in terms of grain yield. It is possible to utilize these genotypes as a genitor in cross-breeding programs for breeding studies for tolerance to high temperatures.

A design and application of compound multi-functional sensor in wood-based panel processing

A compound multi-functional sensor was designed by the study on the on-line testing technology of wood-based panels, and its properties of shape, functions, size, resistance to special environment were studied in details. The operational principles of different sensors, technical flow of manufacturing, development of software systems of special functions, and the assessments of technical specification were also be introduced. This sensor adopted many new technologies, such as the applications of piezoresistant effect and heat sensitive effect can effectively measure the pressure and temperature, digital signal processing technology was used to extract and treat signals, and resist interference, encapsulation technology was used to keep the normal run of sensor under a harsh environment. Thus, the on-line compound multi-functional temperature/pressure sensor can be applied better to supervise the production of wood-based panels. All technical specifications of the compound multi-functional sensor were tested and the results met the requirements of the equipments.

Curative effect of heat-sensitive moxibustion on chronic persistent asthma: a multicenter randomized controlled trial

OBJECTIVE:To compare the curative effects of heat-sensitive moxibustion with conventional drugs on chronic persistent asthma and seek a valuable therapy to replaceWestern Medicine.METHODS:The participants in this multi-center,randomized,and controlled study were randomly divided into two groups:group A(n=144),treated with heat-sensitive moxibustion(50 sessions)and group B(n=144),treated with Seretide(salmeterol50μg/fluticasone 250μg,twice a day).The scores of asthma control test(ACT),forced expiratory volume in 1 second(FEV1),peak expiratory flow(PEF),and attack frequency were measured after 15,30,60,and 90 days of treatment.Patients followed up3 and 6 months after treatment.RESULTS:There was a significant difference(P=0.0002)in the ACT score and lung function between the two groups after 3 months of treatment and(P=0.000 03)during the follow-up visits.In addition,heat-sensitive moxibustion reduced attack frequency in the period from inclusion to the6-month follow-up visit.CONCLUSION:This study shows that heat-sensitive moxibustion may have a comparable curative effect toSeretide(salmeterol/fluticasone)on asthma.

Efficacy of knee-balancing manipulation plus heat-sensitive moxibustion for knee osteoarthritis and its influence on CTX-Ⅰ,TRACP-5b,ADAMTS-4,and MMP-3

Objective To observe the efficacy of knee-balancing manipulation plus heat-sensitive moxibustion in treating knee osteoarthritis(KOA)and its impact on the expression of C-telopeptide of type I collagen(CTX-Ⅰ),tartrate-resistant acid phosphatase 5b(TRACP-5b),A disintegrin and metalloproteinase with thrombospondin motifs 4(ADAMTS-4),and matrix metalloproteinase 3(MMP-3).Methods A total of 134 unilateral KOA patients were randomized into a knee-balancing group,a heat-sensitive moxibustion group,and a joint intervention group.The knee-balancing group received knee-balancing Tuina(Chinese therapeutic massage)manipulation for treatment.The heat-sensitive moxibustion group received heat-sensitive moxibustion treatment.The joint intervention group received the heat-sensitive moxibustion in addition to the knee-balancing manipulation.The intervention period lasted for four weeks.After the treatment,and at the 2-week and 6-week follow-ups,the three groups were assessed using the visual analog scale(VAS)for knee joint pain and Western Ontario and McMaster Universities arthritis index(WOMAC),and clinical efficacy was also evaluated.The enzyme-linked immunosorbent assay was adopted to detect the expression levels of serum CTX-Ⅰ,TRACP-5b,ADAMTS-4,and MMP-3.Results The knee-balancing group had 44 participants,but one dropped out;there was no dropout case among the 44 participants in the heat-sensitive moxibustion group;among the 46 participants in the joint intervention group,two cases dropped out.After the treatment,and at the 2-week and 6-week follow-ups,the total effective rate was found higher in the joint intervention group than in the knee-balancing and heat-sensitive moxibustion groups(P<0.05).Compared with the baseline,the VAS and WOMAC scores and the serum levels of CTX-Ⅰ,TRACP-5b,ADAMTS-4,and MMP-3 decreased significantly in all three groups after treatment and at the 2-week and 6-week follow-ups(P<0.05).At the same three time points,the VAS and WOMAC scores and serum levels of CTX-Ⅰ,TRACP-5b,ADAMTS-4,and MMP-3 were lower in the joint intervention group than in the knee-balancing and heat-sensitive moxibustion groups(P<0.001).Conclusion Either used alone or combined,the knee-balancing manipulation and heat-sensitive moxibustion therapy can improve the symptoms and down-regulate the serum levels of CTX-Ⅰ,TRACP-5b,ADAMTS-4,and MMP-3 in KOA patients,producing durable efficacy;nevertheless,a more significant efficacy can be achieved by combining the two methods.

Drying of suspensions and solutions on inert particle surface in mechanically spouted bed dryer

To eliminate some disadvantages of the conventional spouted bed dryers the mechanically spouted bed （MSB） system was developed. This dryer type is convenient to use inert particles providing an increased surface area for drying of materials of high-moisture content and heat sensitive materials. On three different drying tasks are demonstrated the experimental optimization of process parameters to obtain products of demanded quality. The main object was at drying of AIO（OH） suspension to preserve the particle size under 2.5μm and to obtain product with a moisture content of about 0.05 kg/kg （d.b.）. For this reason a very thin particle coating and intensive abrasion had to be assured. At drying of tomato concentrates the thermoplasticity makes the process very difficult. To jump over the deliquescent and sticky state developed at the critical temperature-moisture content values a very short drying time （8-10 s） must be provided. The third task was to form powder-like product from bovine serum albumin （BSA） solution having very low solid content （2-4%）. The selected process parameters given in this paper resulted in a mean particle size of less than 20 μm while the soluble oreserved orotein content was higher than 90%.
