Classification of atomic-scale multipoles under crystallographic point groups and application to linear response tensors

Four types of atomic-scale multipoles, electric, magnetic, magnetic toroidal, and electric toroidal multipoles, give a complete set to describe arbitrary degrees of freedom for coupled charge, spin, and orbital of electrons. We here present a systematic classification of these multipole degrees of freedom towards the application in condensed matter physics. Starting from the multipole description under the rotation group in real space, we generalize the concept of multipoles in momentum space with the spin degree of freedom. We show how multipoles affect the electronic band structures and linear responses, such as the magneto-electric effect, magneto-current (magneto-gyrotropic) effect, spin conductivity, Piezo-electric effect, and so on. Moreover, we exhibit a complete table to represent the active multipoles under 32 crystallographic point groups. Our comprehensive and systematic analyses will give a foundation to identify enigmatic electronic order parameters and a guide to evaluate peculiar cross-correlated phenomena in condensed matter physics from microscopic point of view.Comment: 37 pages, 4 figures, 32 table

Case report: Usefulness of angioscopy in determining antiplatelet drug reduction after carotid artery stenting

We report a case in which neointima was confirmed by angioscopy and antiplatelet drug administration was reduced 2 months after carotid artery stenting (CAS). A patient in their 80s was scheduled to undergo resection for renal cancer; however, he also had right cervical internal carotid artery stenosis. Because this was a risk for general anesthesia, CAS was performed after first starting dual antiplatelet therapy. Urologically, early reduction of antiplatelet drugs was necessary for a nephrectomy. Although no obvious neointima could be identified on ultrasound 2 months after CAS, thin neointima was observed using angioscopy. Based on the above results, we reduced the antiplatelet drug administration, and then the nephrectomy was performed. Ultimately, no cerebral infarction occurred in the perioperative or postoperative periods. Angioscopy allows for visual confirmation of thin neointima. If sufficient neointima can be confirmed, antiplatelet drug reduction can be performed more safely and reliably

Lifestyle Habits Adjustment for Hypertension and Discontinuation of Antihypertensive Agents

Background: Hypertension is one of lifestyle-related diseases, and prevention and effect of reduction pressure can be expected by non-pharmacological interventions. Authors have continued guidance of adjustment for lifestyle to thousands of hypertensive patients, resulting 4.6%-6.1% case could discontinue hypertensive agents. This study enrolled patients with all necessary related data. Subjects and methods: Subjects were 50 patients with hypertension (M/F: 25/25, age 65.4 ± 8.6 vs. 53.4 ± 6.2 years, BMI 23.4 ± 2.7 vs. 22.3 ± 2.5, respectively), who could discontinued antihypertensive agents. They received consultation and intervention from registered dietitian nutritionists, exercise therapists and nurses. Results: The comparative results on males and females are as follows: smoking habit was 76% vs. 0%, alcohol intake was 60% vs. 0%, diabetes complication was 16% vs. 8%, and hyperlipidemia was 32% vs. 52%, respectively. These cases showed rare to none incidence of cerebral vascular accident (CVA), coronary heart disease (CHD) and chronic kidney disease (CKD). Consultations in median were 4.0 vs. 4.0 times, median weight reduction was 2.2 kg vs. 1.6 kg and median period withdrawal of the drug was 2.0 years vs. 2.5 years. Discussion and conclusion: When living adjustment is advised, blood pressure decreases due to behavior change. Our results suggest that these cases have less arteriosclerosis development, which enables withdrawal of medicine. It is necessary to carefully observe the progress whether the antihypertensive drug will be unnecessary or will be restarted. Current results obtained would become the fundamental data in the future, and the adjustment for diet and exercise would be useful for more adequate treatment for hypertension
