Multivalency-Induced Band Gap Opening at MoS₂ Edges

Lucking, Michael C.,Bang, Junhyeok,Terrones, Humberto,Sun, Yi-Yang,Zhang, Shengbai American Chemical Society 2015 Chemistry of materials Vol.27 No.9

<P>Zigzag edges of monolayer MoS<SUB>2</SUB> and other transition-metal (TM) dichalcogenides are experimentally shown to exhibit strong photoluminescence. Atomic models that have been proposed for these edges, however, are all metallic. Here, we address this puzzle by using first-principles calculations. We found that a more generic electron counting model (ECM) can be developed, which, when coupled with the ability of TM atoms at edges to change their valency from 4+ to 5+, can quantitatively account for the band gap opening at the zigzag edges. Due to the ECM, a 3× periodicity along the zigzag edge is necessary to open the band gap. Moreover, consistent with experiment, oxygen adsorption is shown to open even larger band gaps than intrinsic edges.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/cmatex/2015/cmatex.2015.27.issue-9/acs.chemmater.5b00398/production/images/medium/cm-2015-003989_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/cm5b00398'>ACS Electronic Supporting Info</A></P>

( Udeni Jayalal ),( Soon Ok Oh ),( Robert Lucking ),( Santosh Joshi ),( Jung A Kim ),( Jung Shin Park ),( Jae Seoun Hur ) 한국균학회 2013 Mycobiology Vol.41 No.4

South Korea is covered primarily by temperate vegetation; therefore, foliicolous lichens may not be expected to play an important role in its lichen flora. However, this study describes four foliicolous lichen species, Strigula concreta, S. macrocarpa, S. melanobapha, and S. subelegans, which are new to South Korea. These findings will lead to further research on foliicolous lichens and provide a better understanding of their distribution within the East Asian region. This is the first detailed report on foliicolous lichens and their distribution in South Korea.

Objective : There were variant results for correlation between the postoperative cure rate and valsalva leak point pressure (VLPP) for female stress urinary incontinence (SUI). Therefore the aim of this study was to assess the influence of VLPP on the outcome of suprapubic arch (SPARC) procedure. Materials and Methods : A retrospective analysis was made of 246 women who underwent SPARC procedure for SUI. Based on VLPP, the patients were divided into 2 groups: group A (VLPP<60cmH2O) and group B (VLPP≥60cmH2O). The objective success rate and subjective success rate were assessed. Before surgery, the patients were evaluated with history taking, physical examination, urinalysis and urodynamic studies. The objective success rate was evaluated by clinical examination and the 1-hour pad test postoperatively and the subjective satisfaction rate was assessed using questionnaires for the patients' satisfaction and evaluated by recommendation rates of SPARC procedure to other patients. The objective success rate included cure and improvement, the subjective success rate included satisfaction and fair. Results : The number of patients in each group was 145 patients (group A) and 101 patients (group B). The objective success rate was 99.3% (group A) vs 98.0% (group B) (p=0.285). The subjective success rate was 98.6% (groupA) vs 98.0% (group B) (p=0.500). Recommendation rates of SPARC procedure was 94.5% (group A) vs 95.0% (group B) (p=0.422). Conclusion : It is our belief that SPARC procedure for female SUI is efficacious and safe regardless of preoperative VLPP.

기종성 방광염

Emphysematous cystitis (EC) is a rare complicated lower urinary tract infection (UTI)characterized by air within the bladder wall and lumen. The disease is most common in middle-aged diabetic women. Patients with chronic UTI, indwelling urethral catheters, urinary tract outlet obstruction or neurogenic bladders are predisposed to complicated UTI such as EC. Most patients can be managed by adequate bladder drainage and appropriate antibiotics coverage and operation is needed very rarely. We report a diabetic women with EC who underwent partial cystectomy.

Collecting duct renal cell carcinoma (CDRCC) or Bellini duct carcinoma is a rare type of renal cell carcinoma (RCC), accounting for 0.4% to 1.8% of all RCC. CDRCC is considered to originate from the collecting duct of the kidney and it has a poor prognosis. However, the clinical features of CDRCC remain poorly understood, mainly because only studies with a small series or case reports have been published to date. We experienced a case of CDRCC of kidney.

Renal cell carcinoma is the third most common neoplasia of the genitourinary tract. Its most common type, representing 60% of the cases, is the clear cell carcinoma, with an incidence peak between 50 and 70 years. Metastases are present at the time of diagnosis in approximately 30% of the patients, the major sites being lungs, bones, skin, liver, and brain. But distant metastasis of malignant neoplasm to the masseter muscle is extremely rare. We report a case of renal cell carcinoma (RCC) metastasizing to the masseter muscle.

최초 임상증상으로 볼부위의 종괴로 나타난 전이성 신세포암 : 증례보고

신세포암의 골격근으로의 전이는 매우 드문경우로 현재까지 약 20편정도의 증예 보고만이 있을뿐이다. 우리는 이 증례보고에서 매우 드문 경우인 최초 임상증상으로 볼부위의 종괴를 주소로 내원후 전이성 신세포암으로 진단받은 65세 남자의 증례와 전이성 신세포암이 골격근으로 전이된 경우의 문헌들을 리뷰하였다. 환자는 내원 3개월전 왼쪽 볼부위에 무통성 종괴가 있는것을 처음 인지하였다. 절제된 종괴의 병리학적 소견은 전이성 신세포암으로 나타났으며 영상의학검사상 좌측신장에 6x5㎝ 크기의 종괴를 보였고 양측 폐에 다수의 작은 결절들을 보였다. 환자는 근치적 신절제술을 받았으며 이후 폐전이에 대해 5-fluorouracil, interferon-a과 interleukin-2을 이용한 변역요법을 시행하였다. 이후 폐 전산화단층촬영상 암이 진행된 것으로 나타나 Sutene^(?)을 이용한 경구 표적요법을 시행중이다.

백서의 우울모형에서의 칼슘통로 길항제 에타베린(Ethaverine)의 항우울효과

이상경,김선희,김록우,윤성환,김용관,김경태,김영훈 대한신경정신의학회 2000 신경정신의학 Vol.39 No.2

연구목적: 본 전임상연구에서는 우울증의 두가지 동물모형을 통해 에타베린이 단독 혹은 이미프라민과 병용처치 되었을 때의 효과를 알아보고자 하였다. 방법: 표준화된 검사법인 강제수영검사를 사용하여 옹성백서에게 에타베린(20mg/kg) 및 이미프라민 (20mg/kg)을 단독 혹은 병용 처치하였을 때의 부동시간의 변화를 관찰하였고, 경도의 만성 스트레스를 3주간 가한 후 4주간 에타베린과 이미프라민을 단독 혹은 병용 처치하였을때의 자당섭취량의 변화를 관찰하였다. 결과: 약물을 1회 단기처치 및 7일간 장기처치한 강제수영검사에서 이미프라민 및 에타베린 단독처치는 대조군에 비하여 부동시간의 단축을 보였고 에타베린은 이미프라민의 부동시간 감소에 대한 증강작용을보였다. 경도의 만성스트레스 실험에서도 3주간의 스트레스로 인하여 감소된 백서의 자당섭취량을 이미 프라민 및 에타베린이 회복시켰으며, 치료초기에 두 약물의 병용처치효과가 두드러졌다. 결론: 본 연구의 결과는 에타베린이 향우울 효과를 가지고 있음을 시사하며, 삼환계 항우울제인 이미프라민의 항우울효과를 증강시키므로 에타베린의 임상적 활용 가능성을 보여준다. Objectives: This pre-clinical study was performed to assess the effects of ethaverine in the two kinds of behavioral models of depression in rats. Methods: We observed the changes of the immobility time in the froced swimming test and the quantity of sucrose consumed in the chronic mild stress model, using ethaverine(20mg/kg) alone, imipramine(20mg/kg) alone, or ethaverine and imipramine concomitantly. Results: In the forced swimming test, both single treatment and chronic treatment(for 7days) with imipramine or ethaverine significantly reduced the immobility time, and concomitant chronic treatment with ethaverine potentiated the effect of imipramine. In the chronic mild stress model, both imipramine and ethaverine reversed the decreased sucrose consumption induced by 3-week stress and concomitantly treated ethaverine potentiated the effect of imi-pramine in the early phase of treatment. Conclusions: The data suggest that ethaverine can be used alone or concomitantly with other antidepressants in the clinical situation.
