Serum carboxyterminal cross-linked telopeptide of type 1 collagen (CTX), undercarboxylated osteocalcin (uOC), bone alkaline phosphate (BAP) and vitamin D were assayed.Results: Postmenopausal women with MS had a significantly higher lumber spine BMD than women without MS (p < 0.05). A progressive increase of the BMD at both sites with the number of MS components was observed. Bone turnover markers and vitamin D levels were not significantly influenced by the presence of MS. BMD at both sites positively correlated with body mass index (BMI), waist circumference (WC) and glucose in unadjusted analysis. In multiple regression analysis, WC was independently associated with BMD at both sites, while hypertension was associated only with lumbar spine BMD.Conclusions: In postmenopausal women, MS is associated with increased lumbar spine BMD and this relation is explained mainly by the higher BMI and WC in the MS group.","PeriodicalId":7167,"journal":{"name":"Acta physiologica Hungarica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1556/APhysiol.101.2014.2.10","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"32401534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In pregnant myometrium, the concentration that caused 50% inhibition (IC(50)) was 100 μmol/L for bupivacaine, 157 μmol/L for ropivacaine, > 1000 μmol/L for lidocaine, and 26.3 μmol/L for tetracaine.

In general, MZ twin pairs showed almost identical HRCT features independently of smoking attitude and COPD status.

The autonomic nervous system and its sympathetic arm play important roles in the regulation of blood pressure, and overactivity of sympathetic nerves may have an important role in the development of hypertension and related cardiovascular disorders. The baroreceptor system opposes either increases or decreases in arterial pressure, and the primary purpose of the arterial baroreflex is to keep blood pressure close to a particular set point over a relatively short period of time. The ability of the baroreflex to powerfully buffer acute changes in arterial pressure is well established, but the role of the arterial baroreceptor reflex in long-term control of arterial pressure has been a topic of many debate and controversy for decades. The sympathetic nervous system and arterial baroreceptor reflex control of renal sympathetic nerve activity has been proposed to play a role in long-term control of arterial pressure. The aim of this paper has been to review the postulated role of sympathetic activation.

However, not all studies have found BFR efficacious, possibly due to methodological differences. It is presently unclear whether there are differences between cuffs of similar size (5 cm) but different material (nylon vs. elastic). The purpose was to determine if there are differences in repetitions to fatigue and perceptual ratings of exertion (RPE) and discomfort between narrow elastic and narrow nylon cuffs. Sixteen males and females completed three sets of BFR knee extension exercise in a randomized cross-over design using either elastic or nylon restrictive cuffs applied at the proximal thigh. There were no differences in repetitions to fatigue (marker of blood flow) or perceptual ratings between narrow elastic and narrow nylon cuffs. This data suggests that either elastic or nylon cuffs of the same width should cause similar degrees of BFR at the same pressure during resistance exercise.

Total and bone-specific alkaline phosphatase (ALP and BALP) and C-terminal cross-linked telopeptide (CTX) levels were measured at the beginning and at the end of exercise.

Therefore, walking more significantly reduced the level of CTX than special exercise. The decrease of BALP in TG was considerable but not significant (TG -4.63%, p = 0.091), while BALP levels dropped significantly in CG (-7.65%, p = 0.011), and there was a non-significant difference between the two groups (p = 0.22).
