Studies on quantitative meat productions of Kabir poultry

The research aimed at evaluating the quantitative production of meat (the yield at slaughter, the weight of the cut regions and the weight of the edible organs) in birds of the Kabir breed (10 males and 10 females) slaughtered at the age of 50 days. The fresh slaughter yield was 68.51% in males and 68.12% in females, with an average of 68.31%; after refrigeration the yield, the average value obtained for the two sexes was 67.62% (67.72% in males and 67.51% in females). Regarding the proportion of the cut parts, the average values obtained for the two sexes were 20.22% for the chest (21.02% for males and 19.41% for females), 24.86% for whole legs (25.92% for males and 23.80% for females), 11.28% for wings (11.47% for males and 11.09% for females) and 43.65% for back (41.59% - male and 45.70% female). The average weights determined for the internal organs were 36.32g in males and 31.83 g in females in the case of liver, 8.31 g in males and 6.34 g in females in that of hearts and respectively, of 31.98 g-males and 29.16 g-females in the case of gizzard. In conclusion, it can be stated that the birds of the Kabir breed slaughtered at the age of 50 realize a satisfactory production of meat, both in terms of the yield at slaughter and the weight of the anatomical regions

To date, there are no restorative interventions approved for use in ICH patients, highlighting a critical unmet need. ICH shares some pathological features with other acute brain injuries such as ischemic stroke (IS) and traumatic brain injury (TBI), including the loss of brain tissue, disruption of the blood–brain barrier, and activation of a potent inflammatory response. New biomaterials such as hydrogels have been recently investigated for their therapeutic benefit in both experimental IS and TBI, owing to their provision of architectural support for damaged brain tissue and ability to deliver cellular and molecular therapies. Conversely, research on the use of hydrogels for ICH therapy is still in its infancy, with very few published reports investigating their therapeutic potential. Here, the published use of hydrogels in experimental ICH is commented upon and how approaches reported in the IS and TBI fields may be applied to ICH research to inform the design of future therapies is described. Unique aspects of ICH that are distinct from IS and TBI that should be considered when translating biomaterial‐based therapies between disease models are also highlighted

Archaeometrical Characterization of Romanian Late Bronze Age Ceramic Fragments

Knowledge of the past can provide information to protect the future and the potential of the technological development in the analytical sciences can be successfully applied for the study and conservation of cultural objects. In this context, in the present paper we propose an analytical methodology to characterize seven samples of ancient ceramic objects (dating to the Late Bronze Age). The samples were analyzed using optical microscopy, and all the samples presented a strong inhomogeneity on the surface, as suggested by the different colors of the ceramics. X-ray fluorescence (XRF) results reveal a relatively heterogenous composition of the samples, as well as strong differences between the different surfaces of each sample. By comparative analysis of the diffractograms recorded for both sides of the same samples were observed some differences, especially in terms of relative concentration of the component minerals, and, in lesser content, in terms of new phases present in the samples. Corroborated results obtained by XRF and X-ray diffraction (XRD) offered information regarding mineralogical composition of the samples: for some of them illite/muscovite and plagioclase phases are present in higher quantities or a lower quartz content. The presence of these components was confirmed by Fourier-transform infrared spectroscopy (FTIR) analysis. The thermal analysis completes the analytical investigation of the ceramic samples. The thermal behavior of the sample conducted to some explanation regarding the observed differences, due to the raw materials (that the major clay mineral in the samples is represented by illite) or to environmental factors during their burial in the soil

Anatomical localization of intracranial grade II meningiomas in North-Eastern Romania: Our 25-years experience

Objective. Our research aims to assess a possible connection between tumour localization and histological subtypes of grade II meningiomas. Material and methods. 143 patients with grade II WHO meningiomas underwent surgical resection in "Prof. Dr. N. Oblu" Emergency Clinical Hospital Ia?i between 1990 and 2015. The collected data included: patient age, gender, tumour localization and histopathological diagnosis (atypical, clear cells and chordoid meningioma). Results. 135 (94.4%) of all 143 patients with grade II meningiomas were atypical meningiomas, 6 (4.2%) were cell clear meningiomas and only 2 (1.4%) were chordoid meningiomas. As concerns their distribution by gender, 79 (55.2%) were female and 64 (44.8%) were male. Grade II meningiomas were most commonly located at convexity 49.7% (n=71), followed by skull base in 30.8% (n=44) of the cases and parasagittal/falcine in 14.7% (n=21) of the patients. Conclusions. The most common localization of grade II meningiomas was convexity, followed by skull base, parasagittal/falcine and intraventricular areas. We have also noticed that convexity meningiomas are more frequent in women, unlike the other anatomical localizations in which the male-female ratio is almost equal. Therefore, further research is necessary to determine the role of embryological, anatomopathological and genetic factors in underlying the connection between meningioma grade and anatomical localization

ASSESSING PATIENT SATISFACTION WITH IMPLANT PROSTHETIC WORK. A PRELIMINARY QUESTIONNAIRE-BASED STUDY

Objective. To evaluate the quality of life of edentulous patients with implant prosthetic work. Methods. Retrospective study, between 2015 and 2016, with a group of 50 patients in the over-implantation phase. Patients responded to a satisfaction questionnaire following overdenture prosthesis. Results. Overdenture has improved the quality of life of patients by regaining their self-esteem, regaining the aesthetic, phonetic and mastication functions, as well as the possibility of using a solid consistency diet without the occurrence of pain. Conclusion. The use of overdenture prosthesis is a treatment that gives patients satisfaction from all points of view (functional, psychological, aesthetic and economic). To reflect the reality, future studies will need to obtain information from a larger number of subjects from different backgrounds, being treated in different clinics

A Study on the Contributions of Sonication to the Identification of Bacteria Associated with Intubation Cannula Biofilm and the Risk of Ventilator-Associated Pneumonia

Ventilator-associated pneumonia is one of the most severe complications of critically ill patients that need mechanical respiratory support, as it poses a significant risk of prolonging hospitalization, disability, and even death. This is why physicians worldwide target newer methods for prevention, early diagnosis, and early target treatment for this condition. There are few methods for a quick etiological diagnosis of pneumonia, especially point of care, and most are only readily available in some intensive care units. This is why a new, simple, and cheap method is needed for determining the bacteria that might be infectious in a particular patient. The manner in question is sonication. Method: In this prospective, observational, single-center study, endotracheal cannula specimens will be collected from at least 100 patients in our intensive care unit. This specimen will be submitted to a specific sonication protocol for bacteria to dislodge the biofilm inside the cannula. The resulting liquid will be seeded on growth media, and then a comparison will be made between the germs in the biofilm and the ones in the tracheal secretion of the patient. The primary purpose is to determine the bacteria before the appearance of a manifest infection

Biological Activated Sludge from Wastewater Treatment Plant before and during the COVID-19 Pandemic

The COVID-19 pandemic and the related measures brought a change in daily life that affected the characteristics of the municipal wastewater and further, of the biological activated sludge. The activated sludge process is the most widely used biological wastewater treatment process in developed areas. In this paper, we aim to show the situation of specific investigations concerning the variation of the physicochemical parameters and biological composition of the activated sludge from one conventional wastewater treatment plant from a metropolitan area. The investigations were carried out for three years: 2019, 2020 and 2021. The results showed the most representative taxa of microorganisms: Microtrix, Aspidisca cicada, Vorticella convallaria, Ciliata free of the unknown and Epistylis and Rotifers. Even if other microorganisms were found in the sludge flocs, their small presence did not influence in any way the quality of the activated sludge and of the wastewater treatment process. That is why we conclude that protozoa (especially Flagellates and Ciliates) and rotifers were the most important. Together with the values and variation of the physicochemical parameters, they indicated a good, healthy, and stable activated sludge, along with an efficient purifying treatment process, no matter the loading conditions
