The aim of this study was to investigate the changes caused by the administration of ketoprofen to albino NMRI mice on some hematological, biochemical, and structural parameters. For this purpose, ...the mice were divided into two lots: a control batch and an experimental batch to which ketoprofen was administered subcutaneously at a dose of 10 mg/kg body weight per day for 7 days. A decrease in erythrocyte number and hemoglobin was observed altogether with the increase in white blood cells. Blood biochemistry indicates increased blood glucose, cholesterol, and triglyceride levels. Enzyme values (AST, ALT, and ALP) show a significant increase. Hepatic pathology reveals the enlargement of sinusoidal capillaries, the presence of leukocyte infiltrates associated with necrosis zones.
This study aimed to evaluate the surface roughness evolution of several finished and polished composites when bleaching materials are applied. The research was conducted on four microhybrid or ...nanofilled composites that are used in dental restorations.
For each composite type, 5 samples were selected for control, 5 samples were subjected to the bleaching protocol "office bleach" with 40% hydrogen peroxide, and 5 other samples were subjected to the "home bleach" protocol with 16% carbamide peroxide, resulting in a total number of 60 samples. The surfaces of all the samples were tested for roughness, and the values of the most relevant parameter (Ra), were collected. Comparisons between composites and samples were performed using one-way ANOVA (in Statistical Package for Social Sciences).
After the bleaching protocol with 40% hydrogen peroxide gel, it was found that the roughness of the group increased considerably compared to the control group, so the highest roughness was found at GC Gradia direct anterior group, and the lowest value was registered for the 3M ESPE Valux Plus group. Following the bleaching protocol with 16% carbamide peroxide (home bleach), it was noted that the sample surfaces were not as affected. In this case, the lowest roughness was found at 3M ESPE Valux Plus group, and the highest roughness was registered for the GC G-aenial anterior group. Following the interpretation of the results, all four types of dental composites tested showed significant surface roughness differences between the groups subjected to bleaching protocols and those kept as control (
< 0.05).
The surfaces of the samples were affected by the bleaching protocols by increasing the roughness compared to the control samples.
Composite materials used in dental restorations are considered resistant, long-lasting and aesthetic. As the wear of restorations is an important element in long-term use, the aim of this study was ...to evaluate the surface condition of nanohybrid and microfilled composite resins, after being subjected to the erosive action of dental bleaching protocols. This paper reflects a comparative study between one nanofilled composite and three microfilled composites used in restorations. For each composite, three sets of samples (under the form of composite discs) were created: a control group, an “office bleach” group with discs bleached with 40% hydrogen peroxide gel, and a “home bleach” group with discs bleached with 16% carbamide peroxide gel. Wear was numerically determined as the trace and the coefficients of friction obtained using a tribometer, the ball-on-disk test method, and two balls: alumina and sapphire. For all composite groups, there were statistically significant differences between the wear corresponding to the control and bleaching groups, for both testing balls. Regarding the composite type, the largest traces were recorded for GC Gradia direct anterior, for all groups, using the alumina ball. In contrast, for the sapphire ball, 3M ESPE Filtek Z550 was characterized by the largest traces. With respect to the friction coefficients, the “office bleach” group recorded the largest values, no matter the composite or the ball type used. The 3M ESPE Valux Plus composite recorded the largest friction coefficients for the alumina ball, and 3M ESPE Filtek Z550 for the sapphire ball. Overall, the “office bleach” group was characterized by higher composite wear, compared to the “home bleach” protocol or control group. Nanofilled composite resins showed superior wear resistance to microfilled resins after undergoing a bleaching protocol.
Introduction: Patient satisfaction represents an essential indicator of the quality of care in the medical recuperation sector. This study aimed to identify the degree of satisfaction in patients who ...benefit from medical recuperation services in one private clinic from Romania and the factors that played a part in this respect. Method: An online questionnaire was completed by 105 patients of a private clinic in the period immediately following the opening of the clinic after the quarantine period due to COVID-19. The following concepts were measured: general satisfaction with clinical recuperation services (SG), physician’s behavior (PB), the impact of interventions on the state of health (IHI), modern equipment (ME), and the intention to return to the clinic (IRC). Based on a linear regression model, the impact of PB, IHI, ME, and IRC variables on general satisfaction (SG) was established. Results: The study results confirm the data from studies carried out in different sociocultural contexts in ordinary time, where physician behavior is the most crucial factor in patients’ satisfaction. Therefore, we can say that the physiotherapist’s behavior has an essential role in determining the patients’ satisfaction both in ordinary time and in COVID-19 time. The data in this study reflect the fact that satisfaction with the services offered by a medical recuperation clinic is a predictor for using the services in the future. Still, our study reflects a moderate relationship in intensity.
Academic dishonesty in higher education is an increasingly visible problem throughout the world and in Romania in particular. A total of 1127 university students from six public Romanian universities ...were surveyed for their experiences and beliefs with 22 behaviors that might be considered academically dishonest. A five-factor solution to the frequencies of these behaviors was interpretable and accounted for more than half of the total variance. How acceptable students believed the behaviors were and how often students witnessed other students engage in these behaviors were consistent predictors of the frequency of the behaviors, with small to medium effect sizes. Demographic predictors of these behaviors, including gender, academic specialty, year in school, institution, grade average, and scholarship status, predicted very little variance in the behaviors. Implications and limitations of the study, as well as limitations of research in the field, are discussed.
Background & Aim. Sphincter-saving rectal surgery is prone to cause changes in bowel function associated with Low Anterior Resection Syndrome (LARS). Our aim was to assess LARS-like symptoms within a ...population of 50-80-year old in order to understand the functional disturbances and emotional impact of LARS. Materials and methods: We used a questionnaire to evaluate LARS with the following categories of symptoms: flatulence control, anal incontinence, frequency, clustering and urgency of the stools, and the psycho-emotional impact created by the presence of these symptoms. We calculated the severity of LARS on 343 responders. Results. The average age of the responders (57.4% females) was 60 years. Overall, 48.1% of those questioned had no LARS-associated symptoms, while the rest presented either minor (39.9%) or major (12%) LARS-like symptomatology according to the assessment scale. Women have a higher relative risk (1.32) of having minor or major LARS. The frequency of stools did not correlate with the overall LARS score. The psycho-emotional impact was mostly influenced by the presence of incontinence (p=0.001) and urgency (p=0.05). Discussions. The study highlights the need to integrate the initial status of patients into the overall quantification of the effects of surgery on the quality of life. Age does not influence the prevalence of LARS, but symptoms seem more prevalent in women. The psycho-emotional impact is relevant to the general population, so explanations given during the informed consent and accurate description of potential consequences of surgical intervention increase compliance to ensure better post-operative control of the symptomatology. Conclusions. Deriving a normative LARS-like score may alter the interpretation and discussion of LARS scores for future rectal cancer patients, and it also provides a better understanding of the emotional impact of such symptoms on certain population subsets or cultural groups. Keywords : LARS, general population, incontinence, urgency, psycho-emotional impact Highlights check LARS-like symptoms (with important psycho-emotional impact on the affected persons) may also be present in normal healthy population. check Clinicians should thus estimate to what extent the observed LARS-like symptoms affect the individual before and after treatment.
