Using the concept of onomastic literacy as an analytical tool : A methodological examination of the names of European royal families
2022
Onomastic literacy (the skills needed to interpret the cultural and social phenomena and meanings related to name-giving) are part of a person’s cultural capital. I use this concept, which I have developed, to study personal names in family networks and in royal families in particular. This research combines the approaches and methodologies of collective biography, microhistory and the history of mentalities. The concept of onomastic literacy helps us to contextualize the lives of the research objects more closely as part of the cultures and local communities of their times, thereby revealing the deep-rooted motives behind name choices and the slow change in mentalities affecting naming. pe…
Study on the Correlation Between Working Capital and Economic Value Added for the Companies Relating to the Hotel and Restaurant Industry Listed on t…
2020
In the present study was determined the influence of the value change of the working capital on the variation of the economic value added indicator on a sample consisting of a number of 26 companies (2007-2017) belonging to the hotel and restaurant industry, listed on the Bucharest Stock Exchange. The correlation between the indicators was achieved by using the multiple linear regression method. The study showed that there is a strong link between the two economic indicators, over 80% of the change in economic value being explained by the change in working capital. It was found that a 1% increase in working capital, for the period 2007-2017, had the effect of increasing the economic value a…
Conceptualizing ecosystem tipping points within a physiological framework
2017
Connecting the nonlinear and often counterintuitive physiological effects of multiple environmental drivers to the emergent impacts on ecosystems is a fundamental challenge. Unfortunately, the disconnect between the way “stressors” (e.g., warming) is considered in organismal (physiological) and ecological (community) contexts continues to hamper progress. Environmental drivers typically elicit biphasic physiological responses, where performance declines at levels above and below some optimum. It is also well understood that species exhibit highly variable response surfaces to these changes so that the optimum level of any environmental driver can vary among interacting species. Thus, specie…
Beneficial effects of running and milk protein supplements on Sirtuins and risk factors of metabolic disorders in rats with low aerobic capacity
2019
Background. Physical activity and dietary intake of dairy products are associated with improved metabolic health. Dairy products are rich with branched chain amino acids that are essential for energy production. To gain insight into the mechanisms underlying the benefit of the sub-chronic effects of running and intake of milk protein supplements, we studied Low Capacity Runner rats (LCR), a rodent exercise model with risk for metabolic disorders. We especially focused on the role of Sirtuins, energy level dependent proteins that affect many cellular metabolic processes. Methods. Forty-seven adult LCR female rats sedentary or running voluntarily in wheels were fed normal chow and given suppl…
2016
Background Contractile myofibroblasts (MFs) accumulate in the joint capsules of patients suffering from posttraumatic joint stiffness. MF activation is controlled by a complex local network of growth factors and cytokines, ending in the increased production of extracellular matrix components followed by soft tissue contracture. Despite the tremendous growth of knowledge in this field, inconsistencies remain in practice and prevention.
<p>Effects of losartan and atorvastatin on the development of early posttraumatic joint stiffness in a rat model</p>
2019
Background After a trauma, exuberant tissue healing with fibrosis of the joint capsule can lead to posttraumatic joint stiffness (PTJS). Losartan and atorvastatin have both shown their antifibrotic effects in different organ systems. Objective The purpose of this study was the evaluation of the influence of losartan and atorvastatin on the early development of joint contracture. In addition to joint angles, the change in myofibroblast numbers and the distribution of bone sialoprotein (BSP) were assessed. Study design and methods In this randomized and blinded experimental study with 24 rats, losartan and atorvastatin were compared to a placebo. After an initial joint injury, rat knees were …
Influence of the anti-inflammatory cytokine interleukin-4 on human joint capsule myofibroblasts
2016
Post-traumatic joint contracture was reported to be associated with elevated numbers of contractile myofibroblasts (MFs) in the healing capsule. During the physiological healing process, the number of MFs declines; however, in fibroconnective disorders, MFs persist. The manifold interaction of the cytokines regulating the appearance and persistence of MFs in the pathogenesis of joint contracture remains to be elucidated. The objective of our current study was to analyze the impact of the anti-inflammatory cytokine interleukin (IL)-4 on functional behavior of MFs. Cells were isolated from human joint capsule specimens and challenged with three different concentrations of IL-4 with or without…
Möglichkeiten der CT-Arthrographie in der Diagnostik von Schulterinstabilitäten
1990
In the course of a prospective study, CT arthrography was carried out on 40 patients with shoulder instability. In 35 of these patients a lesion of the capsule and labrum was demonstrated, indicating glenohumeral instability; in three patients this was shown primarily by CT arthrography. In three patients, multidirectional instability was demonstrated. In four patients there was an isolated lesion of the labrum, whereas in one patient all the findings were normal. Compared with the capsulo-labral lesions, bone changes involving the head of the humerus and the glenoid were of lesser importance, although their severity affected the choice of operative treatment in four patients. Fifteen of th…
Unusual manifestation of an osteoid osteoma of the capitate.
1999
A case of osteoid osteoma of the capitate in a 29-year-old male is reported. The patient suffered from unspecific clinical findings and a 3-year history of uncharacteristic wrist pain. Conventional radiographs of the wrist revealed a circumscribed sclerosis in the proximal part of the capitate bone beside a diffuse demineralisation of the carpal bones. Magnetic resonance imaging demonstrated a circumscribed, tumorous lesion with marked enhancement after IV administration of contrast agent and a highly calcified nidus, which was sharply demarcated by a small rim of granulation tissue from the surrounding spongious bone. Based on MRI findings, the diagnosis of an osteoid osteoma was establish…
The Shoulder Girdle
2000
The shoulder girdle is an anatomically complex structure consisting of the scapula, clavicula, proximal humerus, and their articular connections. The wide range of motion is provided by the glenohumeral joint and the two shoulder girdle joints, the acromioclavicular and sternoclavicular joints.
