Nanoscale chirality generated in zinc(II) orthophosphate clusters: evidence by vibrational circular dichroism.

Layered zinc(II) hydroxides (LZH) intercalating the deprotonated forms of -(-) or -(+)-1,1'-binaphthyl-2,2'-diyl hydrogenphosphate (denoted as - or -BNDHPH, respectively) were prepared from Zn(NO) at pH 5 and 60 °C by the mixing method. The obtained hybrid compounds (denoted as - or -BNDHP/LZH, respectively) were heated from room temperature up to 800 °C under nitrogen atmosphere. According to the thermal gravimetric/differential thermal analysis measurements, hydroxyl groups were dehydrated at 270-400 °C, followed by the decomposition of organic components at 420-600 °C.

Cd-content and temperature dependences of hyperfine fields in CdFeO.

Cd-content and temperature dependences of hyperfine fields in CdFeO (0 ≤ x ≤ 0.5) were investigated by means of time-differential perturbed angular correlation spectroscopy with the Cd(←In) probe. It was found that Cd ions selectively occupy the tetrahedral A site in the spinel structure in all the range of the present Cd content x.

[Stanford Type A Acute Aortic Dissection with Leg Ischemia and Visceral Ischemia].

A 52-year-old man developed Stanford type A acute aortic dissection and suffered severe pain in the back and the chest, and numbness of the left lower limb. Contrast-enhanced computed tomography (CT) revealed occlusion of the left iliac artery due to dissection. The celiac artery was also obstructed and the superior mesenteric artery was severely narrowed, but there was no clear sign of organ ischemia.

[Endovascular Stent Grafting Using Gadolinium-based Contrast Agent and Intravascular Ultrasound in a Patient of Iodinated Contrast Media Allergy].

A 75-year-old male with a history of allergy to iodinated contrast media was referred for the treatment of the left subclavian artery aneurysm. The aneurysm was saccular and maximum diameter over 30 mm. Stent grafting was performed with the use of gadolinium-based contrast agent and intravascular ultrasound (IVUS).

[Extended Sandwich Patch Repair with the Right Ventricular Approach for Posterior Ventricular Septal Perforation].

Ventricular septal perforation(VSP) is a catastrophic complication of acute myocardial infarction, and posterior VSP reportedly has worse outcomes. We present a case of a 79-year-old man with posterior VSP following acute myocardial infarction. He underwent percutaneous coronary intervention for acute postero-inferior myocardial infarction due to occlusion of the mid-portion of the right coronary artery.
