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

Evaluation of EGFR, KRAS and BRAF gene mutations in renal cell carcinoma

A subset of renal cell carcinoma (RCC) patients has been shown to respond to anti-EGFR therapy. As KRAS and BRAF mutations are associated with poor response to anti-EGFR therapy in some cancers, it has been suggested that screening for KRAS and BRAF mutations in RCC may be a promising strategy to identify patients who might respond to EGFR-targeted therapy. The aim of this study was to investigate the mutation status of EGFR, KRAS and BRAF in RCC patients. Renal tumors and normal renal samples from forty-eight patients who underwent radical or partial nephrectomy for kidney cancer were used in this study. Histological classification of the tumors was performed according to International Union against Cancer (UICC) / American Joint Committee on Cancer (AJCC) classification. Seventeen patients (48%) had clear-cell RCC, 7 (20%) had chromophobe RCC, and 11 patients (32%) had papillary RCC. DNA isolated from the samples was subjected to melting curve mutation analysis for EGFR, BRAF and KRAS using ABI-3130 DNA sequencer. DNA sequencing analysis of RCC samples, when compared with morphologically normal matched regions, did not show any exon mutations. Our results do not support the notion that EGFR, KRAS and BRAF might be mutated in RCC

The Final Death Blow to the Turkish Constitutional Court

On 22 January 2021, Turkish President Erdoğan appointed Mr. İrfan Fidan to the Turkish Constitutional Court (TCC). Besides his alleged close ties to Erdoğan, Fidan was the prosecutor of many high-profile criminal cases that have been at the heart of the current backlash against democracy and human rights violations in Turkey. The TCC is already borderline “tamed”, serving only occasionally as a Constitutional safeguard. Fidan would be the final blow to shift the balance and slim majorities to fully serve Erdoğan’s interests

Angiogenesis in Inflammatory Bowel Disease

Angiogenesis is an important component of pathogenesis of inflammatory bowel disease (IBD). Chronic inflammation and angiogenesis are two closely related processes. Chronic intestinal inflammation is dependent on angiogenesis and this angiogenesis is modulated by immune system in IBD. Angiogenesis is a very complex process which includes multiple cell types, growth factors, cytokines, adhesion molecules, and signal transduction. Lymphangiogenesis is a new research area in the pathogenesis of IBD. While angiogenesis supports inflammation via leukocyte migration, carrying oxygen and nutrients, on the other hand, it has a major role in wound healing. Angiogenic molecules look like perfect targets for the treatment of IBD, but they have risk for serious side effects because of their nature
