Transient peripheral eosinophilia occurs in several disorders, such as allergic diseases, cancer, and parasitic infections. However, in most cases, their presence is not accompanied by tissue destruction or organ dysfunction. In certain disease states, eosinophils can accumulate in any organ in the body and cause tissue destruction as a result of the eosinophil infiltration or the toxic effects of the degranulated proinflammatory products. Idiopathic hypereosinophilic syndrome is a rare disorder characterized by persistent eosinophilia of an unknown origin, usually associated with a dysfunction of organs such as the heart, lung, skin, and nervous system. Idiopathic hypereosinophilic syndrome usually has an indolent course over a period of several months. However, in some cases, they have grave symptoms if vital organs such as heart and lung are infiltrated. Here we report a case of idiopathic hypereosinophilic syndrome presenting acute pulmonary edema involving the heart, bone marrow, and lung with a review of the relevant literatures.

The objective of this study consists of facilitating seafood consumption by increasing its intake opportunities for consumer through analysis of sliced raw fish. A study on sliced raw fish consumption was conducted on 630 citizens of Busan(252 men and 378 women), attending high school and university, and employedas housekeepers and salaried employees. The goal of the study was to assess the attitude and degree of satisfaction obtained from eating sliced raw fish and ultimately to promote greater seafood consumption. A self-administered questionnaire was used to record the results. The results were as follows : About sixty percent of the respondents appeared to like or not to be reluctant to eating sliced raw fish. The main reasons for favoring sliced raw fish were its taste and nutritious effects. All ages liked sliced raw fish, but teenaged women, on average, tend to dislike sliced raw fish. The most preferred sliced raw fish was flounder. Most of the panelists preferred korean rock fish, and red sea bream due to their ordinary muscle. Sliced raw fish of the 2nd and 3rd variety were the most popular. For most of the sliced raw fish, the own-price elasticity came out to be relatively low. This can be explained by the fact that sliced raw fish is characteristically purchased based more on quality and freshness, than on price. SINGSINGWHE(SSW)-fresh sliced raw fish should be stored at 0$^{\circ}C$ for no longer than 10hrs. Taste, nutritional value and low price have the potential to promote the consumption of seafood. Factors which can reduce the consumption of sliced raw fish were safety due to Vibrio septicemia, rainy day, indistinct origin, and high rices. To promote sliced raw fish consumption, the subjects recommended the quality improvement and low price.

Most people have a desire to live longer. According to ancient Chinese and Korean mythology, Dongfang Shuo (Dongbang Sahk) lived for 18,000 years. According to a WHO report, the average longevity of humans has extended from 50-odd years in the 1960s to 75-85 years in 2016. Parabiosis, the joining to circulatory systems of two animals, was described as early as the 1860s. It provides a powerful experimental model to investigate the effects of one animal on its partner animal in vivo. Research on reverse aging is an immensely popular in parabiosis studies. In this review, the origin of the parabiosis model and important historical findings based on parabiosis models are presented. Surprising and debated discoveries in aging research are also introduced. Using heterochronic parabiosis of connecting circulatory systems of a young mouse and old mouse, various groups claim to have identified a reverse aging factor, growth differentiation factor 11 (GDF11), which was significantly reduced in blood of old mice. Although the potential existence of any one factor or factors that could reverse aging remains to be confirmed, studies have shown that the parabiosis model is powerful enough to detect reverse aging factors.

We consider a receiving node, located at the origin, and a Poisson point process (PPP) that models the locations of the desired transmitter as well as the interferers. Interference is known to be non-Gaussian in this scenario. The capacity bounds for additive non-Gaussian channels depend not only on the power of interference (i.e., up to second order statistics) but also on its entropy power which is influenced by higher order statistics as well. Therefore, a complete statistical characterization of interference is required to obtain the capacity bounds. While the statistics of sum of signal and interference is known in closed form, the statistics of interference highly depends on the location of the desired transmitter. In this paper, we show that there is a tradeoff between entropy power of interference on the one hand and signal and interference power on the other hand which have conflicting effects on the channel capacity. We obtain closed form results for the cumulants of the interference, when the desired transmitter node is an arbitrary neighbor of the receiver. We show that to find the cumulants, joint statistics of distances in the PPP will be required which we obtain in closed form. Using the cumulants, we approximate the interference entropy power and obtain bounds on the capacity of the channel between an arbitrary transmitter and the receiver. Our results provide insight and shed light on the capacity of links in a Poisson network. In particular, we show that, in a Poisson network, the closest hop is not necessarily the highest capacity link.

Background: Duloxetine is an antidepressant that is also useful in chronic neuropathic and central origin pain. In this study, the role of duloxetine in decreasing acute postoperative pain after lumbar canal stenosis surgery is explored. Methods: In this single center, triple blinded, and placebo-controlled trial, 96 patients were randomized for statistical analysis. The intervention group received oral duloxetine 30 mg once a day (OD) for 2 days before surgery, 60 mg OD from the day of surgery to the postoperative second day and 30 mg OD for the next 2 days (a total duration of 7 days). A placebo capsule was given in the other group for a similar time and schedule. The same standard perioperative analgesia protocols were followed in both groups. Results: Total morphine consumption up to 24 hours was significantly decreased in the duloxetine group (P < 0.01). The time to the first analgesia requirement was similar in both groups but the time to the second and third dose of rescue analgesia increased significantly in the duloxetine group. The time to ambulation was decreased significantly (P < 0.01) in the duloxetine group as compared to the placebo group. Pain scores remained similar during most of the time interval. No significant difference was observed in the complication rate and patient satisfaction score recorded. Conclusions: Duloxetine reduces postoperative pain after lumbar canal stenosis surgery with no increase in adverse effects.

New Zealand suffers from regular floods, these being the most common source of insurance claims for damage from natural hazard events in the country. This paper describes the origin and distribution of the largest floods in New Zealand, and describes the systems used to monitor and predict floods. In New Zealand, broad-scale heavy rainfall (and flooding), is the result of warm moist air flowing out from the tropics into the mid-latitudes. There is no monsoon in New Zealand. The terrain has a substantial influence on the distribution of rainfall, with the largest annual totals occurring near the South Island's Southern Alps, the highest mountains in the country. The orographic effect here is extreme, with 3km of elevation gained over a 20km distance from the coast. Across New Zealand, short duration high intensity rainfall from thunderstorms also causes flooding in urban areas and small catchments. Forecasts of severe weather are provided by the New Zealand MetService, a Government owned company. MetService uses global weather models and a number of limited-area weather models to provide warnings and data streams of predicted rainfall to local Councils. Flood monitoring, prediction and warning are carried out by 16 local Councils. All Councils collect their own rainfall and river flow data, and a variety of prediction methods are utilized. These range from experienced staff making intuitive decisions based on previous effects of heavy rain, to hydrological models linked to outputs from MetService weather prediction models. No operational hydrological models are linked to weather radar in New Zealand. Councils provide warnings to Civil Defence Emergency Management, and also directly to farmers and other occupiers of flood prone areas. Warnings are distributed by email, text message and automated voice systems. A nation-wide hydrological model is also operated by NIWA, a Government-owned research institute. It is linked to a single high resolution weather model which runs on a super computer. The NIWA model does not provide public forecasts. The rivers with the greatest flood flows are shown, and these are ranked in terms of peak specific discharge. It can be seen that of the largest floods occur on the West Coast of the South Island, and the greatest flows per unit area are also found in this location.

This study was carried out to determine the effects of olive oil prepared tomato powder (OPTP) used as lycopene source on fresh pork patties. OPTP was not added (0%; C), or was added at 0.25% (T1), 0.5% (T2), 0.75% (T3) and 1.0% (T4) in a basic pork patty formula and patties were stored for 7 days at $5^{\circ}C$. pH values of T3 and T4 were lower (p<0.05) than those of control until storage day 3. However, pH values of treated samples were dramatically increased (p<0.05) after 7 d of storage. Cooking loss values of treatments were lower (p<0.05) than those of control at day 1 of storage. Thiobarbituric acid reacting substances values were lower (p<0.05) in all treatments than in untreated samples during storage. All treated samples had lower values (p<0.05) for lightness ($L^*$) but significantly higher values (p<0.05) for redness ($a^*$) and yellowness ($b^*$) than the untreated samples during storage. Total plate counts of T4 were lower (p<0.05) than others during storage. In sensory evaluation, the scores of color, aroma and overall acceptability in T3 and T4 scored higher (p<0.05) than those of control at days 1 and 3 of storage, however, statistical significance was not found (p>0.05) among the samples after 7 days of storage. In conclusion, tomato powder-treated groups were significantly higher in redness ($a^*$) and yellowness ($b^*$), and lipid oxidation was inhibited, as compared with control during storage. Therefore, as a natural additive, tomato powder could be used to extend the self-life of meat products, providing the consumer with food containing natural additives, which might be seen more healthful than those of synthetic origin.

In order to investigate corelation between contents of dioctylphthalate in polyvinylchloride blent dibutyl tin dilaulate with dibutyl tin maleate as stabilizer and the behaviors of radiation resistance as well as electrical conductivity on irradiated specimens, several observations were carried out. A characteristic peak observed in the range of $1,540-1,640cm^{-1}$ on infrared spectra shows such a sensitive response to radiation as the intensity decreases with increasing doses and that this tendency strongly depressed in the presence of plasticizer. It is seemingly attributed for origin of the peak to the existence of RCOO- ion resulting from dissociation of stabilizere, further the depressive effect of decreasing peak intensity influenced by radiation seems to be caused by resonance absorption in benzen ring being a consistituent of plasticizer. It is also suggestive to be use the peak behavior influenced by radiation as a criterion for the evaluation of radiation resistance of PVC. Further the results obtained from electrical conductivity measurement also exhibit reasonable characteristics explainable with views used for the interpretation of the peak behavior mentioned previousely.

Objective: The objective of this study was to estimate the genetic correlation (rpc) of growth performance between purebred (Duroc and Korean native) and synthetic (WooriHeukDon) pigs using a single-step method. Methods: Phenotypes of 15,902 pigs with genotyped data from 1,792 pigs from a nucleus farm were used for this study. We estimated the rpc of several performance traits between WooriHeukDon and purebred pigs: day of target weight (DAY), backfat thickness (BF), feed conversion rate (FCR), and residual feed intake (RFI). The variances and covariances of the studied traits were estimated by an animal multi-trait model that applied the Bayesian inference. Results: rpc within traits was lower than 0.1 for DAY and BF, but high for FCR and RFI; in particular, rpc for RFI between Duroc and WooriHeukDon pigs was nearly 1. Comparison between different traits revealed that RFI in Duroc pigs was associated with different traits in WooriHeukDon pigs. However, the most of rpc between different traits were estimated with low or with high standard deviation. Conclusion: The results indicated that there were substantial differences in rpc of traits in the synthetic WooriHeukDon pigs, which could be caused by these pigs having a more complex origin than other crossbred pigs. RFI was strongly correlated between Duroc and WooriHeukDon pigs, and these breeds might have similar single nucleotide polymorphism effects that control RFI. RFI is more essential for metabolism than other growth traits and these metabolic characteristics in purebred pigs, such as nutrient utilization, could significantly affect those in synthetic pigs. The findings of this study can be used to elucidate the genetic architecture of crossbred pigs and help develop new breeds with target traits.
