Lentinula edodes is known by oak mushroom. It has been favored as delicious and nutritious food and the low-calorie food with a high nutritional value. It is also functional food since it contains a material well-known for its medicinal benefits. Since the growth and quality of oak mushrooms are sensitively affected by environmental conditions, an adequate environmental control is very essential to improve the yield and quality under protected cultivation. The main objectives of the study were to investigate cultural characteristics of mycelial growth and in vitro fruiting of Lentinula edodes. The optimum culture media for mycelial growth of L. edodes were PDA and MYA. Similarly, optimum temperature was 25℃. Malt extract(2%) and yeast extract(0.2%) were optimum carbon and nitrogen sources. Optimal culture period was 110~120 days in sawdust medium. Among different five log types, highest mycelial growth and fruiting productivity were observed in Quercus variabilis sawdust(20.9%).

JAK2 V617F mutation is a common event in chronic myeloproliferative disorders. However, de novo acute myeloid leukemia with JAK2 V617F is rarely encountered. The authors report the case of a 74-year-old male with de novo acute myeloblastic leukemia without maturation (AML M1) and a JAk2 V617F heterozygotic mutation. Despite treatment with standard AML regimens, the patient died 2 months after a diagnosis of acute leukemia. This case of an AML patient with a JAK2 V617F mutation with a poor prognosis suggests that despite its rarity, a JAK2 V617F mutational study be considered for prognostic purposes in AML.

Wheat (Triticum aestivum L.) grain texture is an important determinant of milling properties and end product use. Two linked genes, puroindoline a (PINA) and puroindoline b (PINB), control most of the genetic variation in wheat grain texture. Wheat seed proteins were examined to identify PINA and PINB gene using two pre-harvest sprouting wheat cultivars; Jinpum (resistant) and Keumgang (susceptible).Wheat seed proteins were separated by two-dimensional electrophoresis with IEF gels over pH ranges: pH 3-10. A total of 73 spots were digested with trypsin resulting peptide fragmentation were analyzed by matrix assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF/MS). Mass spectra were automatically processed and searched through NCBInr, SWISS-PORT and MSDB database with mono isotopic masses and complete gene sequence were found by UniProt database. Puroindoline a and puroindoline b that is responsible for grain texture related with baking performance and roughness. Two spots were found Pin b (16.7 kDa) and Pin a (16.3 kDa) in Jinpum compare to seven spots were identified Pin a (16.1 kDa, 16.3 kDa) and Pin b (16.7 kDa, 9.5 kDa and 14.4 kDa) in Keumgang. Some selected spots were identified puroindoline like grain softness protein (16.9 kDa, 17 kDa and 18.1 kDa) in Keumgang. Moreover, to gain a better inferring the identification of puroindoline related proteins using proteomics, we accomplished a complete gene sequence of PINA and PINB gene in pre-harvesting sprouting wheat seeds between resistant (Jinpum) and susceptible (Keumgang).
