    Most of the population in the Moldavian Plateau feeds with water from the groundwater, without being analyzed from a qualitative point of view. The present research aims to evaluate the physic-chemical parameters of the water in the Băiceni locality, Botosani County, in order to establish the water quality classes. For this present study, a series of field measurements were carried out during August 6-9, 2014, which determined the depth of the groundwater, the water column in the wells of Băiceni, as well as the physico-chemical parameters (temperature, pH, the dissolved oxygen and the amount of salts) of 52 fountains water samples. Measurements were performed using the Hach Lange Multiparameter. From a qualitative point of view, the water in Băiceni has a pH between 7.12 and 8.13. Dissolved oxygen varies depending on the depth and location of the well (in a flat or hill area). Dissolved oxygen in flat areas can also reach 0.52 mg/l in water and decrease with depth. In the hill areas, the dissolved oxygen has higher values, with maximum values of 7.83 mg/l. The total amount of salt varies depending on the type of soil. Higher values were registered in the wells on the slopes of Baiceni Hill (maximum value of 3620 mg/l). The lowest amount of salt was recorded in the northeastern part of the locality, with a value of 483 mg/l

    Mucin plays a very important role in the physiological function of the stomach in all species, but the representation of mucin-secreting cells differs from species to species. The aim of this study was to highlight these cells in the stomach of the Wistar rat. For histological investigations, fragments of the stomach from the three main regions (cardiac, fundic and pyloric) were harvested from four Wistar rats and further stained with PAS and Alcian blue methods. The histochemical results showed the presence of mucin-secreting cells in the examined tissues. An intense PAS positive reaction was found in the surface epithelium cells of the gastric mucosa and in the cells lining the gastric crypts in all the three segments. In the deep glandular structures, the cells of the cardiac and fundic glands are PAS negative, while those of the pyloric glands are all PAS positive. For Alcian blue reaction, the cells lining the gastric mucosa and the crypts in the three regions of the stomach were negative. In the glands, the cells of the cardiac and fundic glands were Alcian negative while in the pyloric glands, a limited number of cells arranged in the deep third of the glands showed a weak positive Alcian reaction. In conclusion, the vast majority of glandular cells in the rat's stomach do not synthesize acidic mucins, except for cells in the deep part of the pyloric glands, which synthesize small amounts of such mucins

    The mammalian tongue plays a fundamental role in various physiological and behavioral activities. Significant morphological variations have been recorded in the tongue of several species. This study aims to obtain detailed histological and morphometric information about the filiform papillae on the surface of rat tongue. The tongues of five 10-month-old Wistar rats were utilized, which were later examined with a stereo-microscope. Fragments from the three regions of the tongue were collected for histological investigations. The tongue of the Wistar rat has an intensely keratinized stratified squamous epithelium, with the highest degree of keratinized epithelium covering the filiform papillae. The filiform papillae differ in density, with the highest density recorded on the posterior part of the lingual body and the lowest density on the protuberance. The shortest filiform papillae were observed on the apex of the tongue and the tallest on the anterior part of the lingual body. Interestingly, the orientation of the filiform papillae on the lingual protuberance was inclined posteroanteriorly, in the opposite way as compared to the papillae from all the other regions of the tongue. Histologically, a difference was recorded in the structure of the covering epithelium of the anterior vs. the posterior face of the filiform papillae

    Background and Objectives: Cortisol, the stress hormone, is an important factor in initiating and maintaining lactation. Maternal suffering during pregnancy is predictive for the initiation and shorter duration of breastfeeding and can also lead to its termination. The aim of this study is to evaluate the relationship between the level of salivary cortisol in the third trimester of pregnancy and the initiation of breastfeeding in the postpartum period in a cohort of young pregnant women who wanted to exclusively breastfeed their newborns during hospitalization. Materials and Methods: For the study, full-term pregnant women were recruited between January and May 2022 in the Obstetrics and Gynecology Clinic of the Mureș County Clinical Hospital. Socio-demographic, clinical obstetric and neonatal variables were collected. Breastfeeding efficiency was assessed using the LATCH Breastfeeding Assessment Tool at 24 and 48 h after birth. The mean value of the LATCH score assessed at 24 and 48 h of age was higher among mothers who had a higher mean value of salivary cortisol measured in the third trimester of pregnancy (p Results: A quarter of pregnant women had a salivary cortisol level above normal limits during the third trimester of pregnancy. There is a statistically significant association between maternal smoking, alcohol consumption during pregnancy and the level of anxiety or depression. Conclusions: The most important finding of this study was that increased salivary cortisol in the last trimester of pregnancy was not associated with delayed initiation/absence of breastfeeding

    Dentists play an essential role in the treatment of dental and periodontal traumatic injuries by providing early and correct treatment. The purpose of the present study was to assess the level of knowledge of dental residents regarding dental trauma. The cross-sectional study was conducted at the Faculty of Dental Medicine within the “Grigore T. Popa” University of Medicine and Pharmacy in Iasi, Romania on a sample of 366 residents in General Dentistry, Pediatric Dentistry and Periodontology. To assess their knowledge, a questionnaire was created containing 18 questions about the clinical signs and therapy of dental trauma, with a focus on tooth avulsion. A very low level of knowledge (<25%) was found only for the type of splinting required to maintain an avulsed tooth on the arch. The highest number of correct answers was provided by the residents in Periodontology. Physiological serum as storage medium was recognized by a percentage of 75.9–80% of the subjects, and 60–77% of them recognized pulp necrosis as complication of dental avulsion. The study underlines the need to introduce in the curriculum of all categories of residents additional information, not only in the already existent theoretical form, but also as possible scenarios of various clinical situations

    OVERVIEW OF ORAL HEALTH RELATED QUALITY OF LIFE INDICATORS

    The instruments that evaluate the health-related quality of life are extremely useful in the medical practice and research since they allow the full approach of patient’s general status. They come in the shape of questionnaires whose usage may be carried out either by creating one’s own questionnaire or by translating one from the literature. Regardless of the chosen method, the questionnaire must meet a series of characteristics that may make it easy to understand and use. In the field of dentistry, indicators falling into several categories have been validated: some of them address the population groups of different ages; others address the evaluation of therapeutic needs while others appreciate the impact determined by the specific oral disorders. Out of the multitude of indicators that may be found in the literature, those that are frequently used in population studies stand out due to their superior psychometric characteristics, limited scales and easy codification possibilities. A special category is represented by the indicators for the assessment of oncologic patient’s life quality, and instruments that explore the diverse facets of this disorder are validated such as post-irradiation sequels, complications of the surgical treatment, and the impact on the general health state. Another utility of these instruments refer to the possibility of identification of the oral disorders and the therapeutic needs in persons that cannot come to the dental office, such as the disabled and the institutionalized elderly
