The Slaughtening Causes with Dental and Gingival Lesions in Dairy Cows within Postmortem Period

Background: A regular and balanced feeding is essential for the animals in order to maintain their normal physiological function and be productive at the desired level. Digestion activities start with chewing in the mouth and the healthy dental arch is needed to perform a complete chewing function. Abnormal dental development and other dental pathologies impair digestive functions by negatively affecting chewing functions. The aim of the present study was to classified dental anomalies, dental degenerations, dental and gingival lesions seen in dairy cows and was aimed to reveal these lesions and depending on these disorders the reasons for slaughtering in dairy cows.Materials, Methods & Results: The material of this study consists of 600 dairy cows, being slaughtered for a year, and 170 dairy cows, detected dental anomalies, dental degenerations and dental-gingival lesions in the postmortem examination. Detailed macroscopic and radiological examinations of mandibles and maxillae of the dairy cows with dental and gingival lesions in postmortem examination were performed. The detailed information of the cases, such as: age, race, breeding, living region and slaughtering causes, etc. of dairy cows, suffering from dental lesions was recorded from slaughterhouse data access. In this study, 87 cases (51.18%) of the determined dental lesions were defined as dental degeneration, 34 cases (20%) as caries, 30 cases (17.64%) as dental abnormalities in the formation and dental arch and 19 cases (11.18%) as periodontal inflammation.Discussion: In dairy cow breeding, there is a close relationship between production costs and business profitability and animal disease and fertility problems. Although the existence of negative effects of dental lesions directly on the digestive functions is known in dairy cattle breeding; there was no study about the state of dental diseases in dairy cow. In this respect, this research is quite important both for revealing the proportion of dental diseases seen in dairy cow and for drawing attention to the relationship between these diseases and the reasons for slaughtering of dairy cow. In this study, various dental anomalies, dental degenerations, dental and gingival lesions (28.33%) were detected in 170 dairy cows; The decreased milk production in 38 cases (22.35%), infertility in 65 cases (38.24%), gastrointestinal system diseases such as abomasal dislocation, constipation and indigestion in 38 cases (22.35%), foot diseases in 19 cases (11.18%) and economic reasons in 10 cases (5.88%) were determined as slaughtering reasons of the cases. The results of this research indicate that dental and gingival lesions may be regarded as preliminary results in the development of digestive system diseases, and then the various detailed clinical studies are needed to determine whether there is a relationship between digestive system diseases and dental diseases. As a result; this study first classified the dental lesions determined after slaughter in cattle and revealed the relationship between the reasons for slaughtering of dairy cows of the determined dental lesions. The results obtained in this study showed that dental anomalies, caries and periodontal inflammation effect significantly on the dairy cow fertility

Accumulation of selenium in different wheat genotypes and its protective role against various abiotic stress factors

Plant-based foods play a critical role in covering daily requirements of human beings for energy and minerals, especially in the developing world. Most of the nutritional compounds existing in cereal grains are the major protective agents against different chronic diseases. One particular compound with high protective effect against different diseases such as cancer and cardiovascular diseases is selenium (Se). It is widely believed that some forms of selenium (Se) are among the most effective anti-carcinogenic compounds. Studies conducted in different countries revealed that wheat is one of the best Se source for human beings. Wheat is, therefore, an important targeted stable food for enrichment (biofortification) with Se. Selenium is also believed to act protective roles in plants against different abiotic stress factors. However, various controversial results are available in literature regarding the protective roles of Se in plants. In the present study, several experiments have been conducted i) to understand better the protective role of Se in plants under different stress factors, ii) to improve Se status of plants by treating seeds with Se (soaking seeds in a Se-containing solution), and iii) to screen various modern and wild wheat genotypes for their Se accumulation capacity in shoot and seed. In the experiment with seed treatment of Se, the results obtained were promising for improving seed Se concentration. In plants derived from the seeds treated with Se by soaking in a Se-containing solution (up to 5 mM), the seed Se concentration increased from 44 μg kg-1 (non-treated seeds) to 216 μg kg-1 seed (Se-treated seeds). . Seed Se treatment could be a practical approach for enrichment of wheat seeds with Se. Several Triticum dicoccoides genotypes and modern wheat cultivars were investigated for their capacity in Se uptake and accumulation in shoot following application of sodium selenate to soil. The results indicated that the Triticum dicoccoides genotypes tested did not show a promising genetic variation in shoot Se accumulation, and were not superior when compared to the modern wheat genotypes in terms of shoot Se concentration. A nutrient solution experiment was established to follow the Se uptake and accumulation of modern wheat cultivars and Triticum spelta genotypes. In this experiment, some Triticum spelta genotypes were identified showing high Se uptake capacity. Such new genotypes with high Se uptake capacity might be a valuable genetic resource for breeding programs to transfer high Se uptake trait to high-yielding cultivars. Selenium is an essential nutrient for human beings, but not for higher plants. However, in literature, controversial results exist about its beneficial effects on plant growth. By using both wheat and maize plants, greenhouse and growth chamber experiments have been conducted to collect information about the role of Se in improving growth under different stress factors such as drought, salinity, flooding and low temperature. The results obtained indicated that Se has no beneficial effect on plant growth under the stress conditions mentioned. In the experiment with low temperature stress the level of antioxidative defense enzymes (e.g., superoxide dismutase, ascorbate peroxidase and glutathione reductase) were measured in maize plants with and without Se supply. vii Increasing Se supply did not result in a consistent effect on activity of antioxidative defense enzymes under both normal and low temperature. A similar result was also found in seeds enriched with Se by foliar application of Se. The seeds differing in Se concentrations were not different in their total antioxidative capacity. The result of this thesis indicate that i) treating seeds with Se (soaking seeds in a Se-containing solution up to 5 mM) might be a practical approach to improve shoot and grain Se concentration, ii) modern wheat and tetraploid wild wheat Triticum dicoccoides genotypes tested in the present study were not promising genetic sources for improving shoot Se concentration, iii) Triticum spelta genotypes have been identified showing high Se uptake capacity which might be exploited in breeding programs, and iv) Se has no consistent beneficial effects on plant growth and antioxidative enzyme activity under various abiotic stress factors

Comparison of Feedforward Perceptron Network with LSTM for Solar Cell Radiation Prediction

Intermittency of electrical power in developing countries, as well as some European countries such as Turkey, can be eluded by taking advantage of solar energy. Correct prediction of solar radiation constitutes a very important step to take advantage of PV solar panels. We propose an experimental study to predict the amount of solar radiation using a classical artificial neural network (ANN) and deep learning methods. PV panel and solar radiation data were collected at Duzce University in Turkey. Moreover, we included meteorological data collected from the Meteorological Ministry of Turkey in Duzce. Data were collected on a daily basis with a 5-min interval. Data were cleaned and preprocessed to train long-short-term memory (LSTM) and ANN models to predict the solar radiation amount of one day ahead. Models were evaluated using coefficient of determination (R2), mean square error (MSE), root mean squared error (RMSE), mean absolute error (MAE), and mean biased error (MBE). LSTM outperformed ANN with R2, MSE, RMSE, MAE, and MBE of 0.93, 0.008, 0.089, 0.17, and 0.09, respectively. Moreover, we compared our results with two similar studies in the literature. The proposed study paves the way for utilizing renewable energy by leveraging the usage of PV panels

Safety and efficacy of Amplatzer duct occluder II and konar-MF™ VSD occluder in the closure of perimembranous ventricular septal defects in children weighing less than 10 kg

IntroductionDevice closure of perimembranous ventricular septal defects (pmVSD) is a successful off-label treatment alternative. We aim to report and compare the outcomes of pmVSD closure in children weighing less than 10 kg using Amplatzer Duct Occluder II (ADOII) and Konar-MF VSD Occluder (MFO) devices.MethodsRetrospective clinical data review of 52 children with hemodynamically significant pmVSD, and sent for transcatheter closure using ADOII and MFO, between January 2018 and January 2023. Baseline, procedural, and follow-up data were compared according to the implanted deviceResultsADOII devices were implanted in 22 children with a median age of 11 months (IQR, 4.1–14.7) and weight of 7.4 kg (IQR, 2.7–9.7). MFO devices were implanted in 30 children with a median age of 11 months (IQR, 4.8–16.6) and weight of 8 kg (IQR, 4.1–9.6). ADOII were implanted (retrograde, 68.1%) in defects with a median left ventricular diameter of 4.6 mm (IQR, 3.8–5.7) and right ventricular diameter of 3.5 mm (IQR, 3.1–4.9) while MFO were implanted (antegrade, 63.3%) in defects with a median left ventricular diameter of 7 mm (IQR, 5.2–11.3) (p > 0.05) and right ventricular diameter of 5 mm (IQR, 2.0, 3.5–6.2) (p < 0.05). The procedural and fluoroscopy times were shorter with the MFO device (p < 0.05). On a median follow-up of 41.2 months (IQR, 19.7–49.3), valvular insufficiency was not observed. One 13-month-old child (6.3 kg) with ADOII developed a complete atrioventricular heart block (CAVB) six months postoperative and required pacemaker implantation. One 11-month-old child (5.9 kg) with MFO developed a CAVB 3 days postoperative and the device was removed. At 6 months post-procedure, only one child with MFO still experiences a minor residual shunt. There was one arterio-venous fistula that resolved spontaneously.ConclusionBoth the MFO and ADOII are effective closure devices in appropriately selected pmVSDs. CAVB can occur with both devices. The MFO is inherently advantageous for defects larger than 6 mm and subaortic rims smaller than 3 mm. In the literature, our series represents the first study comparing the mid-term outcomes of MFO and ADOII devices in children weighing less than 10 kg

Dilemma after termination of pregnancy due to urogenital fetal anomalies: Discrepancy between prenatal ultrasonographic diagnosis and autopsy

Objective To evaluate the agreement and disagreement between prenatal ultrasound and fetal autopsy findings in pregnancy terminations due to urogenital anomalies. Methods Of 453 pregnancy terminations performed due to fetal anomalies, 82 cases with urogenital anomalies on either prenatal ultrasound or fetal autopsy were included in this retrospective study. The discrepancy between prenatal ultrasound and fetal autopsy findings on urogenital anomaly findings was evaluated. Results Complete agreement between prenatal ultrasound and fetal autopsy findings was noted in 33 (40.2%) cases (particularly for megacystis, bilateral renal agenesis, and infantile polycystic kidney), whereas partial agreement (anal atresia and horseshoe kidney as additional minor findings) and altered diagnosis were noted in 12 (14.6%) and 8 (9.8%) cases, respectively. Disagreement was noted in 29 (35.4%) cases including anomaly only on autopsy in 20 (24.3%) cases (renal agenesis, horseshoe kidney and multicystic dysplastic kidney in particular) and anomaly only on ultrasound in 9 (10.9%) cases. Conclusions Accordingly, our findings indicate fetal autopsy to be a method of vital importance in complementing prenatal diagnosis; it may add valuable information that may improve future pregnancy management and counseling of parents, and hence prenatal ultrasound and fetal autopsy should be regarded as complementary techniques

Evaluation of inflammatory status in blood in patients with rosacea

Abstract Rosacea is a chronic inflammatory skin disease that is characterized by recurrent episodes of erythema, telangiectasia and papulopustular lesions. Although the pathogenesis is not well established, growing knowledge suggests that multiple etiological factors play a role resulting in inflammation. The aim of the present study is to investigate inflammatory status of patients with rosacea by evaluating CBC parameters and systemic immune inflammation (SII) index and compare these parameters with control group. Thus, it is aimed to understand the role of systemic inflammation in the pathogenesis of the disease. This retrospective, case–control study included 100 patients with rosacea and 58 sex- and age-matched controls. Laboratory examinations including CBC, ESR, CRP, HDL, LDL, and triglyceride levels were recorded and neutrophil–lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), and platelet-lymphocyte ratio (PLR), monocyte-to-high-density lipoprotein ratio (MHR) and SII index were calculated. Monocyte and platelet count, SII index, ESR and CRP were significantly higher in patients with rosacea than in the control group. No statistically significant difference was found in other parameters. There was no significant correlation between disease severity and ESR, CRP, and SII index. The findings of this study suggest that apart from the inflammatory pathways at the level of skin, there is an inflammatory state in the blood of patients. Rosacea is a skin disease, but it may have systemic implications and/or associations that need to be clarified completely
