Microvascular endothelial dysfunction precipitates cardiovascular disease mortality in patients with type 2 diabetes mellitus (T2DM). However, the relationship between glycemic management and microvascular endothelial function of these patients remains ill defined. We investigated the association between skeletal muscle microvascular endothelial function with glycemic management (HbA1c) and responses to an oral glucose challenge (OGTT) in 30 patients with T2DM (59 ± 9 years, 31.2 ± 5.1 kg/m2 , HbA1c = 7.3 ± 1.3%). On study day 1, microvascular endothelial function was quantified as the increase (Δ from rest) in forearm vascular conductance (FVC, ml/min/100 mmHg) during intra-arterial acetylcholine infusion at 4.0 and 8.0 μg/dl forearm volume/min (ACh4 and ACh8, respectively). [Glucose] and [insulin] were measured in a fasted state as well as following a 75 g OGTT on a second day with an additional fasting blood sample collected to measure HbA1c. FVC increased (Δ) 221 ± 118 and 251 ± 144 ml/min/100 mm Hg during ACh4 and ACh8 trials, respectively (p 7.0%, respectively. Our data show glycemic management is related to acetylcholine-mediated vasodilation (e.g., microvascular endothelial function) in skeletal muscle of patients with T2DM.Trandolapril, an angiotensin-converting enzyme inhibitor prodrug, needs to be activated by carboxylesterase 1 (CES1) in the liver to exert its intended therapeutic effect. A previous in vitro study demonstrated that the CES1 genetic variant G143E (rs71647871) abolished CES1-mediated trandolapril activation in cells transfected with the variant. This study aimed to determine the effect of the G143E variant on trandolapril activation in human livers and the pharmacokinetics (PKs) and pharmacodynamics (PDs) in human subjects. We performed an in vitro incubation study to assess trandolapril activation in human livers (5 G143E heterozygotes and 97 noncarriers) and conducted a single-dose (1 mg) PK and PD study of trandolapril in healthy volunteers (8 G143E heterozygotes and 11 noncarriers). The incubation study revealed that the mean trandolapril activation rate in G143E heterozygous livers was 42% of those not carrying the variant (p = 0.0015). The clinical study showed that, relative to noncarriers, G143E carriers exhibited 20% and 15% decreases, respectively, in the peak concentration (Cmax ) and area under the curve from 0 to 72 h (AUC0-72 h ) of the active metabolite trandolaprilat, although the differences were not statistically significant. Additionally, the average maximum reductions of systolic blood pressure and diastolic blood pressure in carriers were ~ 22% and 23% less than in noncarriers, respectively, but the differences did not reach a statistically significant level. In summary, the CES1 G143E variant markedly impaired trandolapril activation in the human liver under the in vitro incubation conditions; however, this variant had only a modest impact on the PK and PD of trandolapril in healthy human subjects.Post-transplantation malignancy is one of the most common complication-related mortality in transplant recipients. Here, we report the case of a kidney transplant patient for 2 years with malignant pleural effusion that was subsequently diagnosed as malignant pleural mesothelioma.Bovine spongiform encephalopathy (BSE) is a kind of prion disease caused by proteinase K-resistant prion protein (PrPSc ) in cattle. Although BSE has been reported worldwide, BSE-infected cases have never been reported in Korea. In a previous study, we identified BSE-related somatic mutation E211K in 3 Korean Holstein cattle. In Korea, the BSE surveillance system has been established. However, several genetic factors have not been controlled simultaneously thus far. In the present study, we performed enhanced surveillance of prion disease-related factors in Korean cattle, including Holstein cattle and Hanwoo (Korean native cattle), which is widely raised for meat. ATR inhibitor 2 We investigated the germline mutation E211K at codon 211 of the PRNP gene and analysed genotype, allele and haplotype frequencies of the 23- and 12-bp insertion/deletion polymorphisms of the PRNP gene using direct DNA sequencing. In addition, we investigated linkage disequilibrium (LD) and compared haplotype distributions of polymorphisms among cattle breeds. Furthermore, we carried out BSE diagnosis in the medulla oblongata (MO) of Korean cattle including 3 Korean Holstein cattle carrying somatic mutation E211K using Western blotting analysis. We did not find the E211K mutation in the PRNP gene in any of the Korean cattle and found significantly different genotype, allele and haplotype distributions of the 23- and 12-bp insertion/deletion polymorphisms of the PRNP gene in male Holstein compared with male Hanwoo, female Hanwoo and total Hanwoo. In addition, only male Holstein showed weak LD between 23- and 12-bp insertion/deletion polymorphisms. Furthermore, the PrPSc bands were not detected in all Korean cattle tested. To the best of our knowledge, the enhanced surveillance system of BSE was conducted for the first time in Korean cattle.

How to best classify the Stage III and IV periodontitis cases that share common features of the most severe clinical attachment loss and the most severe radiographic bone loss?

Two patients presented features of generalized periodontitis, with severe probing depth and clinical attachment loss that would meet inclusion in both Stage III and IV. The cases retained all teeth but were further complicated by teeth drifting and secondary occlusal trauma. Appropriate disease classification required clinical judgement and led to the final classification of Stage III, Grade C for both cases.

Patient-based clinical judgement, aiming for long-term preservation of natural dentition, drives the final assignment of staging when the case falls in the "gray zone" that focuses on major differences in Stage III and IV periodontitis.
