Larva. Unknown COI profile. We obtained a region data set of 686 nucleotides for five paratypes. No sequence divergence was detected at the infraspecific level. Base frequencies were: A = 27.1 %, C = 25.4 %, G = 18.5 %, and T = 29.0%. 16 S rDNA. We obtained a partial region data set of 965 bases for five paratypes of this novel species. Mean base frequencies were as follows: A = 42.4 %, C = 19.7 %, G = 9.7 %, and T = 28.2 %. Kimura 2 -pairwise divergences within the new species ranged from 0.1 % to 0.5 %. Distribution. Korea (Ui-do Island). Biology. This species remains unknown for detailed biological information. We can only provide brief collecting information that they was caught during the day under some logs and driftage deposited on the beach (Figs. 3, 4). Some individuals were collected by pitfall traps, with each trap containing a small amount of a mixture of 10 volumes of 100 % ethyl alcohol and one volume of pupal broth extracted from Bombyx mori (L.); the traps were left overnight. Etymology. This new species was named A. (S.) uidoensis based on its collection locality, Ui-do Island, Korea. Notes. Within the region including Korea and Japan, this novel species closely resembles A. (S.) ryukyuensis Kishii 1985 from the Ryukyu Islands, Japan, in general appearance and body color. Agrypnus (S.) uidoensis sp. nov. has a distinctly carinate anterior margin of the hypomeral groove for reception of the fore tarsi, the prosternal process is extends straight in the posterior direction, the scutellum is more weakly inwardly concave, especially in male genitalia, the median lobe is slightly longer than the paramere, and the lateral margin of the subapical barb of the paramere is slightly inclined and almost parallel-sided at the base. In contrast, A. (S.) ryukyuensis has indistinct anterior margins of the hypomeral groove, the prosternal process is bent slightly inwardly behind the procoxal cavities, the scutellum is strongly concave inwardly, the median lobe of the male genitalia is equal in length to the paremere apex, and the lateral margin of the subapical barb of the paramere is more strongly inclined and clearly concave at the base. Agrypnus (S.) uidoensis is also separated from A. (S.) taciturnus and A. (S.) sauteri by general body color, the ratio of the length and width of the fourth antennomeres, and the differences in male genital shape as given above in the key. The molecular sequence data set of COI and 16 S rDNA of mtDNA will be useful to search for the unknown larva, which is expected to have same genetic information with adult of this novel species, as well as in determining the relationship between congeners of Sabikikorius and status for further systematic study.

Impact of Chemotherapy-Induced Ovarian Dysfunction on Response to Neoadjuvant Chemotherapy in Breast Cancer
No full textBackground. The association between chemotherapy-induced ovarian dysfunction (CIOD) and response to neoadjuvant chemotherapy (NAC) is not known. We therefore investigated the impact of CIOD on response to NAC in breast cancer patients according to estrogen receptor (ER) status. Methods. In total, 343 premenopausal breast cancer patients treated with NAC between 2006 and 2010 were analyzed. Clinical responses were determined based on changes in tumor size measured using breast MRI. Patients with complete response or partial response were considered to have clinical response. Results. After completion of NAC, 264 of 343 patients (76.9 %) developed CIOD. The clinical response rate was significantly higher in patients with CIOD than those without CIOD (65.2 vs. 51.9 %; p = 0.033). Additionally, the mean follicle-stimulating hormone (FSH) level after NAC was significantly higher in patients with clinical response (FSH 68.7 +/- 34.5 vs. 59.8 +/- 34.3 IU/L; p = 0.021). Multivariate analysis showed an independent association of CIOD to clinical response (OR 0.523, 95 % CI 0.297-0.918; p = 0.024). However, we observed no differences in the pathologic complete response (pCR) rate between patients with and without CIOD (8.7 vs. 6.3 %; p = 0.497). Subgroup analysis according to ER status showed that the association between CIOD and clinical response was significant in ER-positive but not ER-negative breast cancer (p = 0.025 and 0.818, respectively). Conclusions. CIOD during NAC is significantly associated with clinical response, but not pCR. Moreover, this association is only observed in ER-positive breast cancer, suggesting that the moderate difference in response to NAC is possibly a hormonal effect of chemotherapy-induced ovarian dysfunction.N

No full text학위논문(석사) - 한국과학기술원 : 전기 및 전자공학과, 1994.2, [ ii, 94 p. ]In this paper, we suggest a performance analysis and design method for an asymptotically reliable serial production system. The performance is approximated by an asymptotic technique and Taylor series expansion. Using a quality control device and feedback buffer, we present several control schemes to reduce waste materials and enhance the performance. An open-loop system is that its throughput is controlled only by a QCD. And there are two feedback systems, an old-first system and old-last system. The approximation is validated by a simulation and case study. The results seem to have an acceptable error.한국과학기술원 : 전기 및 전자공학과
Safety and effectiveness of transarterial embolization for splenic artery hemorrhage in patients undergoing radical gastrectomy
No full textBackground Perigastric lymph nodes are dissected during gastrectomy, potentially resulting in life-threatening postoperative bleeding. Purpose To evaluate the safety and effectiveness of transarterial embolization (TAE) for bleeding from the splenic artery in patients who underwent gastrectomy. Material and Methods Between January 2004 and December 2016, 14,523 patients underwent gastrectomy at our institution, and ten patients (nine men; mean age = 64.7 years; age range = 51-80 years) underwent TAE for postoperative bleeding from the splenic artery. The location of bleeding was classified as either: (i) the main splenic artery (MSA) or (ii) the parenchymal splenic artery (PSA). The clinical outcomes of TAE were explored. Results Bleeding occurred at a median of 13.5 days (range = 4-34 days) after gastrectomy. The onset of bleeding was late in all patients and clinically manifested as abdominal bleeding in seven patients and luminal bleeding in three patients. Technical and clinical success rates were 100% and 70%, respectively. The three major complications occurred only in patients with MSA bleeding, resulting in two 30-day mortality cases and one splenic abscess with fistula formation to the jejunum. The causes of death were infarctions in the spleen and/or remnant stomach and sepsis. Conclusion TAE seems to be effective in stabilizing patients with bleeding from the splenic artery. Moreover, TAE with curative intent may be performed for bleeding from the PSA; however, further resection of the remnant stomach and/or spleen seems to be required to avoid sepsis and mortality in case of bleeding from the MSA.restrictio
肝コンパートメント症候群を疑われ経動脈塞栓術にて治療した2症例
No full textWe herein present two cases suspected of having liver compartment syndrome that were successfully managed with transarterial embolization (TAE). The first patient was a 40-year-old female involved in a car accident. Contrast-enhanced computed tomography (CT) showed a large intraparenchymal hematoma and active hemorrhaging in the hematoma. Transarterial embolization was performed. A hepatofugal portal flow was only detected in the right lobe of the liver, and a normal antegrade flow was observed in the left lobe. The second patient was a 73-year-old man who had fallen down a flight of stairs. Contrast-enhanced CT showed a large intraparenchymal hematoma. On angiography, a small hemorrhage was observed and TAE was performed. A hepatofugal portal flow was detected in the right lobe of the liver. Liver compartment syndrome is defined as intraparenchymal hypertension induced by a large subcapsular hematoma in a patient with blunt hepatic injury. Liver compartment syndrome causes a disruption in the normal liver circulation and may result in either hepatic ischemia or Budd-Chiari syndrome. It is important to prevent an enlargement of the hematoma by applying TAE
