Facile preparation of oriented nanoporous silica films from solvent-free liquid-crystalline mixtures.

Chemical communications (Cambridge, England)

Mizoshita N, Tani T, Inagaki S.
PMID: 23023655
Chem Commun (Camb). 2012 Nov 11;48(87):10772-4. doi: 10.1039/c2cc36306b.

Mixtures of an amphiphilic perylene bisimide derivative and tetramethoxysilane in the absence of solvents have been found to exhibit stable columnar liquid-crystalline phases which transform into macroscopically oriented nanoporous silica films as a result of simple mechanical shearing.

Ultramicroscopy. 2016 Nov;170:43-59. doi: 10.1016/j.ultramic.2016.08.006. Epub 2016 Aug 06.

Advances in scanning transmission electron microscopy (STEM) techniques have enabled us to automatically obtain electron energy-loss (EELS)/energy-dispersive X-ray (EDX) spectral datasets from a specified region of interest (ROI) at an arbitrary step width, called spectral imaging (SI). Instead of...

Case Rep Oncol. 2015 Nov 01;8(3):530-5. doi: 10.1159/000442347. eCollection 2015.

Pemetrexed is an antifolate agent that is regarded as an alternative second-line chemotherapy against advanced or metastatic urothelial carcinoma (UC). However, there is limited information on pemetrexed in a third-line setting. We report a case of metastatic UC treated...

Determination of three-dimensional strain state in crystals using self-interfered split HOLZ lines.

An experimental method to measure the strain through the thickness of a crystal is demonstrated. This enables the full three-dimensional stress-strain state of a crystal at the nanoscale to be determined taking the current practice from two-dimensional strain state...

The use of a Mitsunobu reagent for the formation of heterocycles: a simple method for the preparation of 3-alkyl-5-aryl-1,3,4-oxadiazol-2(3H)-ones from carboxylic acids.

Chemical communications (Cambridge, England)

Sugimoto O, Arakaki T, Kamio H, Tanji K.
PMID: 24870809
Chem Commun (Camb). 2014 Jul 14;50(55):7314-7. doi: 10.1039/c4cc01971g.

The reaction of carboxylic acids with Mitsunobu reagents, prepared by the reaction of triphenylphosphine with dialkyl azodicarboxylates, followed by heating at 180-190 °C under solvent-free conditions, afforded 3-alkyl-5-aryl-1,3,4-oxadiazol-2(3H)-ones. This facile and convenient method readily provides the 1,3,4-oxadiazolone ring systems...

Influence of life stress, 5-HTTLPR genotype, and SLC6A4 methylation on gene expression and stress response in healthy Caucasian males.

Biology of mood & anxiety disorders

Biol Mood Anxiety Disord. 2015 May 14;5:2. doi: 10.1186/s13587-015-0017-x. eCollection 2015.

BACKGROUND: Previous research reported that individual differences in the stress response were moderated by an interaction between individuals' life stress experience and the serotonin transporter-linked polymorphic region (5-HTTLPR), a common polymorphism located in the promoter region of the serotonin...

Clinical characteristics of pain originating from intra-articular structures of the knee joint in patients with medial knee osteoarthritis.

SpringerPlus

PMID: 24386615
Springerplus. 2013 Nov 23;2:628. doi: 10.1186/2193-1801-2-628. eCollection 2013.

PURPOSE: Although disease progression of osteoarthritis has been well documented, pain pathophysiology is largely unknown. This study was designed with two purposes: 1) to characterize patients with knee pain predominantly originating from intra-articular structures and 2) to describe the...
