A 64-year-old man underwent MRCP for further examination of gallbladder stones and IPMN of branch-type (IPMN-Br) was pointed out. Yearly MRCP had revealed the gradual increase of the cystic components, marked dilation of the main pancreatic duct (MPD), and...

Self-organized 2D periodic arrays of nanostructures in silicon by nanosecond laser irradiation.

Applied optics

Nayak BK, Sun K, Rothenbach C, Gupta MC.
PMID: 21629312
Appl Opt. 2011 Jun 01;50(16):2349-55. doi: 10.1364/AO.50.002349.

We report a phenomenon of spontaneous formation of self-organized 2D periodic arrays of nanostructures (protrusions) by directly exposing a silicon surface to multiple nanosecond laser pulses. These self-organized 2D periodic nanostructures are produced toward the edge as an annular...

Study on Al-Si alloy-based nanocomposites with dispersed detonation nanodiamonds.

Effect of substituent of β-diketones on the synergistic extraction of lanthanoids with linear polyether.

Talanta

Gagabe GF, Satoh K, Sawada K.
PMID: 21530778
Talanta. 2011 May 30;84(4):1047-56. doi: 10.1016/j.talanta.2011.03.008. Epub 2011 Mar 12.

The synergistic extraction of 14 trivalent lanthanoids (Ln(3+)) into 1,2-dichloroethane with a linear polyether (DEO6), HO(C(2)H(4)O)(6)C(12)H(25), and β-diketones (HA) having different substituents was investigated at 25.0°C. The HAs used were trifluoroacetylacetone (Htfa), thenoyltrifluoroacetone (Htta), benzoyltrifluoroacetone (Hbta), naphthoyltrifluoroacetone (Hnta), and...

Strangulation caused by a small bowel epiploic appendage: report of a case.

Case reports in gastroenterology

Nemoto H, Yoshizawa Y, Hibi K, Saito M, Ishibashi K, Sanada Y, Tate G.
PMID: 21490891
Case Rep Gastroenterol. 2008 Jul 01;2(2):214-8. doi: 10.1159/000135609.

While many recent cases of colonic epiploic appendage causing acute abdomen have been reported, such appendages of the small bowel are extremely rare. We present a 59-year-old woman in whom a small bowel epiploic appendage caused volvulus. She presented...

Two-step synthesis of difluoromethyl-substituted 2,3-dihydrobenzoheteroles.

Organic letters

Fujita T, Sanada S, Chiba Y, Sugiyama K, Ichikawa J.
PMID: 24552502
Org Lett. 2014 Mar 07;16(5):1398-401. doi: 10.1021/ol5001582. Epub 2014 Feb 19.

3-Difluoromethylated 2,3-dihydrobenzoheteroles, 2,3-dihydrobenzofurans, 2,3-dihydrobenzothiophenes, and indolines were readily synthesized from ortho-heterosubstituted bromobenzenes, 2-bromophenols, 2-bromobenzenethiols, and 2-bromoanilines, respectively, in two steps: (1) γ-selective allylic substitution of 3-bromo-3,3-difluoropropene with heteronucleophiles and (2) intramolecular radical cyclization of the resulting 3,3-difluoroallylic compounds.

Malignant melanoma with probable smooth muscle differentiation.

Case reports in dermatology

Morimoto A, Asai J, Wakabayashi Y, Komori S, Hanada K, Takenaka H, Konishi E, Katoh N.

Case Rep Dermatol. 2014 Jan 24;6(1):16-9. doi: 10.1159/000358375. eCollection 2014 Jan.

Malignant melanomas occasionally exhibit various divergent differentiation types. Of these, smooth muscle differentiation is extremely rare; only 1 case has been reported in the literature until recently. We report an extremely rare case of malignant melanoma with smooth muscle...

Homozygosity for Non-H1069Q Missense Mutations in ATP7B Gene and Early Severe Liver Disease: Report of Two Families and a Meta-analysis.

Most patients with Wilson's disease (WD) are compound heterozygote, which complicates establishing genotype-phenotype correlations. We identified five patients who presented with early and/or severe hepatic disease who are homozygous for W939C missense mutation on exon 12 of ATP7B. We...

Review to better understand the macroscopic subtypes and histogenesis of intrahepatic cholangiocarcinoma.

World journal of gastrointestinal pathophysiology

Sanada Y, Kawashita Y, Okada S, Azuma T, Matsuo S.
PMID: 25133021
World J Gastrointest Pathophysiol. 2014 Aug 15;5(3):188-99. doi: 10.4291/wjgp.v5.i3.188.

Intrahepatic cholangiocarcinoma is macroscopically classified into three subtypes, mass-forming-type, periductal infiltrating-type, and intraductal growth-type. Each subtype should be preoperatively differentiated to perform the valid surgical resection. Recent researches have revealed the clinical, radiologic, pathobiological characteristics of each subtype. We...
