To allow for a quick conversion of the proprietary sequence data from various sequencing platforms, sequence format conversion toolkits are required that can be easily integrated into workflow systems. In this respect, a format conversion tool, as well as quality conversion tool would be the minimum requirements to integrate reads from different platforms. We have developed the Pyrus NGS Sequencing Format Converter, a simple software toolkit which allows to convert three kinds of Next Generation Sequencing reads, into commonly used fasta or fastq formats. The converter modules are all implemented, uniformly, in Java GUI modules that can be integrated in software applications for displaying the data content in the same format.

Pelvic lipomatosis is a condition characterized by a nonmalignant overgrowth of normal fat in the perirectal and perivesical spaces in the pelvis which may be to occur obstructive uropathy. On cystography the full bladder has an abnormal shape as a gourd, banana, pear or inverted tear-drop. Compulerized tomography shows the bladder and rectosigmoid surrounded and displaced by homogeneous tissue with a low attenuation coefficient and the CT features provide diagnostic proof or pelvic lipomatosis. We present a case of pelvic Lipomatosis.

Kluyveromyces fragilis KCTC 7260 and Saccharomyces cerevisiae KCTC 7904, which both grew well in pear marc extract, were selected and their growth profiles and physiological functionalities were determined. Both of the selected yeasts established maximal growth by 20 hr of cultivation at 30degrees C in pear marc extract. The cell-free extracts showed high antihypertensive angiotensin I-converting enzyme inhibitory activity of 68.9% and 52.1%, respectively. The extracts also displayed 9.2 U/mL and 12.0 U/mL of protease activity, respectively.

Pear is one of the main fruits with thousands of years of cultivation history in China. There are more than 2000 varieties of pear cultivars around the world, including more than 1200 varieties or cultivars in China (Legrand et al., 2016). Xinjiang Uygur Autonomous Region is an important pear production region in China with 30 of varieties or cultivars. Pyrus sinkiangensis is the most popular variety, which is mainly distributed in Xinjiang (Zhou et al., 2018). Chlorogenic acid (CGA), p-coumaric acid, and arbutin are the main polyphenols in pear fruit, and their levels show great differences among different varieties (Li et al., 2014). CGA is a potential chemo-preventive agent, which possesses many important bioactivities including antioxidant, diabetes attenuating, and anti-obesity (Wang et al., 2021). Therefore, the specific CGA content of a variety is considered the embodiment of the functional nutritional value of pears.

Two autopsy cases of asphyxia due to oxygen deficiency are reported. The first case is that a 38-year-old man died in a storehouse. Many pears were stored in a storehouse and the its atmosphere was strictly controlled. The second case is that a 42-year-old man died in the boiler room of a fishing ship. Much amount of Freon gas escaped due to a defect of the refrigerator in the boiler room. The victim entered the boiler room because he repaired the refrigerator. But, the victim died when he entered the boiler room immediately. In this article, the autopsy findings and the contents of the investigation of scene of two cases are described.

BACKGROUND: Tetranychus urticae (two spotted spider mite, TSM) is considered to be an important outdoor allergen, especially among farmers as an occupational allergen. TSM may be an important allergen in Cheonan area because this area is surrounded by many pear orchards where TSM is commonly found. OBJECTIVES: To determine the sensitization rate to TSM in Cheonan area. MATERIALS AND METHODS: Rates of sensitization to common inhalant allergens were analyzed in the 456 patients who visited the allergy clinic in Dankook University Hospital, and skin prick tests were done with 55 common inhalent allergens and TSM extract. RESULTS: The sensitization rate to Dermatophagoides farinae (37.7%) was highest followed by TSM (29.6%) and 25 (5.5%) patients were sensitized to TSM only. Sensitization rate to TSM was the highest in the third and fourth decades. Up to 50% of asthmatics aggravated during the summer season were sensitized to TSM. CONCLUSION: TSM was the second most common sensitized allergen in patients visiting the allergy clinic in Cheonan area. These results suggest that TSM must be an important outdoor allergen in rural areas.

The purpose of this research was to investigate consumption and satisfaction of Takju (Makgeolli) among consumers ages 20 to 29 living in Seoul and Gyeonggi province. It was found that 86.2% of the respondents drank Takju once or twice a month, and the high satisfaction group drank Takju with a frequency of 8 times a month (P<0.01). Respondents selected market (44.4%) and restaurants (34.9%) as the most common place of purchase, whereas pub (42.2%) and Takju bar (32.8%) were the drinking places selected. Regarding the preferred ingredients, respondents liked pear the most followed by Lycium chinense, corn, pine nuts, ginseng, and citrus fruit. The most compatible foods with Takju were identified as Buchimgae (Jeon) (97.4%), Kimchi (45.6%), Bokkeum (36.4%), Namul & Muchim (25.0%), and Jjim (21.5%). Pajeon was mentioned as the most compatible food with Takju, followed by Bulgogi, Gamjatang, Agwijjim, Dubukimchibokkeum, and Ojingeotwigim. Regarding consumers' satisfaction of Takju, taste was the most highly valued, with color, price, alcohol content, function, flavor, diversity of raw materials, and accuracy of label also highly considered. Further, to formulate a plan to encourage consumption of Takju, the high satisfaction group decided that promotion of local festivals and events related to Takju, standardization of quality, creation of brands, expansion of distribution network, and organization of relevant departments are the most important compared to other items (P<0.05).

The variation of the vibration characteristics of a Huanghua pear was investigated using finite element simulations. A new image processing technique was used to obtain the unsymmetrical and un-spherical geometrical model of a pear. The vibration characteristics of this type of pear with the correlation of its behavior with geometrical configurations and material characteristics were investigated using numerical modal analysis. The results showed that the eigenfrequency increased with the increasing pear Young's modulus, while decreased with increasing pear density, and decreased with increasing pear volume. The results of this study provided foundation for further investigations of the physical characteristics of fruits and vegetables by using finite element simulations.

Scab disease caused by Venturia nashicola is of agroeconomic importance in cultivation of Asian pear. However, little is known about the degree of genetic diversity in the populations of this pathogen. In this study, we collected 55 isolates from pear scab lesions in 13 major cultivation areas in Korea and examined the diversity using sequences of internal transcribed spacer (ITS) region, β-tubulin (TUB2), and translation elongation factor-1α (TEF-1α) genes as molecular markers. Despite a low level of overall sequence variation, we found three distinctive subgroups from phylogenetic analysis of combined ITS, TUB2, and TEF-1α sequences. Among the three subgroups, subgroup 1 (60% of isolates collected) was predominant compared to subgroup 2 (23.6%) or subgroup 3 (16.4%) and was distributed throughout Korea. To understand the genetic diversity among the subgroups, RAPD analysis was performed. The isolates yielded highly diverse amplicon patterns and none of the defined subgroups within the dendrogram were supported by bootstrap values greater than 30%. Moreover, there is no significant correlation between the geographical distribution and the subgroups defined by molecular phylogeny. Our data suggest a low level of genetic diversification among the populations of V. nashicola in Korea.

The isolation of a causal pathogen from pear fruits showing lesions of blue mold was carried out, which were preserved in the packinghouse of Anseong for the export to the United States. When the lesion of pears (Pyrus pyrifolia Niitaka) was checked in packinghouse, their fruit epidermis over decayed parts varied from light tan to dark brown. Also, the decayed flesh was soft and watery, and separated easily from the healthy tissue. Based on the cultural and morphological characteristics, the fungus (IL-12 isolate) was identified as Penicillium aurantiogriseum. This is the first report associated with blue mold of pear caused by P. aurantiogriseum in Korea.
