Degradability characteristics of soybean meal treated with formaldehyde in the rumen

Bu çalışma, farklı düzeylerdeki formaldehit muamelesinin soya küspesinin (SK) rumendeki kuru madde (KM), ham protein (HP), efektif kuru madde (EKMP) ve efektif protein parçalanabilirliği (EPP), ile bunlara ait parçalanma parametreleri (a, b, a+b, c) üzerine etkisini incelemek amacıyla yapılmıştır. Çalışmada SK ham protein miktarının %0, 0.3, 0.6 ve 0.9'u düzeyinde formaldehit ile muamele edilerek 2, 4, 8, 16, 24 ve 48 saatlik sürelerde nanende inkubasyona tabi tutulmuştur. Muamelesiz ve %0.3, 0.6 ve 0.9'u düzeyinde formaldehit muameleli SK'nin 48 saatlik inkubasyonda kuru madde parçalanabilirliği sırasıyla %89.38, 85.04, 77.09, 70.81 ham protein parçalanabilirliği %87.67, 79.98, 68.42, 58.61 olarak bulunmuştur (P < 0.01). Yine k=0.05 de efektif kuru madde parçalanabilirliği %58.58, 55.15, 52.38, 49.85 efektif ham protein parçalanabilirliği ise %49.48, 44.55, 39.75, 36.73 olarak tespit edilmiştir (P < 0.01). Çalışmada parçalanma parametrelerinin de (b, a+b) muamelelerden önemli derecede etkilendiği saptanmıştır (P < 0.05). SK'nin gerek kuru madde gerekse ham protein parçalanma oranlarının formaldehit muamelesi ile önemli derecede azaldığı, bu azalmanın formaldehit düzeyi ile doğru orantılı olduğu belirlenmiştir.This study was conducted to determine the effects of different level of formaldehyde treatments on dry matter (DM), crude protein (CP), effective DM (EDMD), effective CP (ECPD) degradabilities and degradation kinetic parameters of soybean meal in the rumen. Soybean meal was treated with 0, 0.3, 0.6, and 0.9% formaldehyde and then incubated in the rumen for 2, 4, 8, 24, and 48 hours. Degradability of DM was 89.38, 85.04, 77.09, and 70.81 degradability of CP was 87.67, 79.98, 68.42, and 58.61% for soybean meal treated with 0, 0.3, 0.6, and 0.9%, respectively (P &lt; 0.01). At the passage rate of 0.05, EDMD was 58.58, 55.15, 52.38, and 49.85% and ECPD was 49.48, 44.55, 39.75, and 36.73% for increasing level of formaldehyde respectively (P &lt; 0.01). There were also significant effects of formaldehyde treatments on &quot;b&quot; and &quot;a+b&quot; kinetic parameters (P &lt; 0.05). In conclusion, degradabilities of DM and CP in the rumen decreased accordingly with increased levels of formaldehyde treatment of soybean meal

The effect of serum and follicular fluid anti-Mullerian hormone level on the number of oocytes retrieved and rate of fertilization and clinical pregnancy

WOS: 000408979800002PubMed: 28058394OBJECTIVE: The objective of this study was to evaluate the relationship between oocyte yield, fertilization, and clinical pregnancy (CP), and anti-Mullerian hormone (AMH) level in serum and follicular fluid during in vitro fertilization treatment. METHODS: Forty-four infertile women who underwent IVF treatment using multiagonist protocol were included in this study. Baseline level of AMH in serum and follicular fluid was measured on third day of menstrual cycle. AMH level in serum and follicular fluid was then measured again on day of oocyte pick-up. Pearson correlation and binary regression tests were used for statistical analysis. For Type 1 error, p= 5% was selected as cut-off value for statistical significance. RESULTS: Serum AMH level was positively correlated with total number of oocytes retrieved and rate of fertilization and CP (r= 0.397, p= 0.008; r= 0.401, p= 0.007; and r= 0.382, p= 0.011, respectively). There was significantly negative correlation between serum level of follicle-stimulating hormone (FSH) and fertilization rate (r=-0.320; p= 0.034), as well as serum FSH level and CP rate (r=-0.308; p= 0.042). There were no significant correlations between AMH level in follicular fluid and IVF treatment outcomes. CONCLUSION: Serum AMH levels may be more reliable for prediction of total number of oocytes retrieved and rate of fertilization and CP than AMH levels in follicular fluid

Childhood Trauma and Dissociation in Schizophrenia

Background: This study is concerned with relationships between childhood trauma history, dissociative experiences, and the clinical phenomenology of chronic schizophrenia. Sampling and Methods: Seventy patients with a schizophrenic disorder were evaluated using the Structured Clinical Interview for DSM-IV, Dissociative Experiences Scale, Dissociative Disorders Interview Schedule, Positive and Negative Symptoms Scales, and Childhood Trauma Questionnaire. Results: Childhood trauma scores were correlated with dissociation scale scores and dissociative symptom clusters, but not with core symptoms of the schizophrenic disorder. Cluster analysis identified a subgroup of patients with high dissociation and childhood trauma history. The dissociative subgroup was characterized by higher numbers of general psychiatric comorbidities, secondary features of dissociative identity disorder, Schneiderian symptoms, somatic complaints, and extrasensory perceptions. A significant majority of the dissociative subgroup fit the diagnostic criteria of DSM-IV borderline personality disorder concurrently. Among childhood trauma types, only physical abuse and physical neglect predicted dissociation. Conclusions: A trauma-related dissociative subtype of schizophrenia is supported. Childhood trauma is related to concurrent dissociation among patients with schizophrenic disorder. A duality model based on the interaction of 2 qualitatively distinct psychopathologies and a dimensional approach are proposed as possible explanations for the complex relationship between these 2 psychopathologies and childhood trauma.

Body mass index and complications following major gastrointestinal surgery: a prospective, international cohort study and meta-analysis.

AIM: Previous studies reported conflicting evidence on the effects of obesity on outcomes after gastrointestinal surgery. The aims of this study were to explore the relationship of obesity with major postoperative complications in an international cohort and to present a meta-analysis of all available prospective data. METHODS: This prospective, multicentre study included adults undergoing both elective and emergency gastrointestinal resection, reversal of stoma or formation of stoma. The primary end-point was 30-day major complications (Clavien-Dindo Grades III-V). A systematic search was undertaken for studies assessing the relationship between obesity and major complications after gastrointestinal surgery. Individual patient meta-analysis was used to analyse pooled results. RESULTS: This study included 2519 patients across 127 centres, of whom 560 (22.2%) were obese. Unadjusted major complication rates were lower in obese vs normal weight patients (13.0% vs 16.2%, respectively), but this did not reach statistical significance (P = 0.863) on multivariate analysis for patients having surgery for either malignant or benign conditions. Individual patient meta-analysis demonstrated that obese patients undergoing surgery for malignancy were at increased risk of major complications (OR 2.10, 95% CI 1.49-2.96, P < 0.001), whereas obese patients undergoing surgery for benign indications were at decreased risk (OR 0.59, 95% CI 0.46-0.75, P < 0.001) compared to normal weight patients. CONCLUSIONS: In our international data, obesity was not found to be associated with major complications following gastrointestinal surgery. Meta-analysis of available prospective data made a novel finding of obesity being associated with different outcomes depending on whether patients were undergoing surgery for benign or malignant disease
