ABSTRACT
Background@#Pre-implantation Genetic Testing for Aneuploidy (PGT-A) has enabled IVF specialists to screen embryos for abnormalities in chromosome number and structure. Subsequently, healthy embryos are selected for transfer, decreasing the rate of spontaneous miscarriages and improving pregnancy outcomes. In spite of this, almost only half of the PGTdetermined euploid embryos result in a pregnancy. @*Objective@#This study aimed to determine what other factors among euploid embryo transfers will have an association with successful implantation and live birth. @*Methods@#This study retrospectively analyzed 159 IVF-PGS cycles performed in CARMI SLMCGC from January 2017 to December 2019. Of these, a total of 231 euploid embryos (86 single embryo transfers and 73 double embryo transfers) were assessed. The relationship of eight predictive variables (maternal age, maternal BMI, etiology of infertility, history of failed IVF, blastocyst expansion stage, ICM grade, TE grade and endometrial thickness on transfer) with regard to the outcome of successful implantation and live birth among single or double euploid blastocyst transfers were determined via logistic regression analysis. @*Results@#Overall, the implantation rate was significantly lower when using B-grade ICM or C-grade ICM blastocysts as compared to A-grade ICM blastocysts (OR 0.54, 95% CI 0.356- 0.815, p = 0.003). With regard to live birth rate, the success of transfer is statistically lower when using a B-grade or C-grade ICM blastocysts as compared to A-grade ICM blastocysts (OR 0.55, CI 0.354-0.863, p = 0.009). Other predictive factors such as maternal age, maternal BMI, etiology of infertility, number of previous IVF, blastocyst expansion stage, trophectoderm grade and endometrial thickness had no apparent effect on the outcome of implantation and live birth. @*Conclusion@#Present study results suggest that only the ICM grade of euploid blastocysts correlates with implantation and live birth in IVF-FET cycles. Therefore, the selection of euploid blastocysts based on the presence of a higher grade ICM is the most predictive factor that determines success among those undergoing IVF with PGT-A.

Abstract Background: There is a comprehensive understanding of the role of dietary fiber as a nutrient and its function during digestion in cattle. On the other hand, the role of fiber digestion in goats has not received similar attention. Objective: To evaluate the effects of different ratios of forage neutral detergent fiber (fNDF) and non-fibrous carbohydrates (NFC) on ruminal fermentation products, and in vitro neutral detergent fiber (NDF) digestibility in goats. Methods: A 3 × 5 factorial arrangement in a completely randomized design with three fNDF levels (100, 190, and 290 g/kg) and five NFC levels (350, 400, 450, 500, and 550 g/kg) was used. The experiment was performed in vitro. Two ruminally fistulated goats were used as rumen liquid donors. Results: The ratios between fNDF and NFC affected all ruminal parameters (p<0.05). Increasing NFC levels in diets containing 100 and 290 g/kg fNDF resulted in linear increase (p<0.05) in ammonia concentration after 48 h fermentation. There was no adjustment of linear models (p>0.05) for pH values. Total volatile fatty acids (VFA) and their individual molar proportions were affected (p<0.05) at all fNDF and NFC levels. The NDF digestibility was not affected (p>0.05) by fNDF or NFC levels, except for diets containing 290 g/kg fNDF, which were fit to a quadratic model (p<0.05). Conclusion: The relationship between fNDF and NFC concentrations affect the fermentation end products and in vitro NDF digestibility. NFC plays a more consistent role than fNDF in the ruminal microbial ecosystem of goats during in vitro fermentation.
Resumen Antecedentes: Aunque hay una amplia comprensión del papel que juega la fibra dietética como nutriente y su función durante la digestión en el ganado vacuno, el papel de la digestión de la fibra en las cabras no ha recibido una atención similar. Objetivo: Evaluar los efectos de diferentes proporciones de fibra detergente neutra proveniente del forraje (fNDF) y carbohidratos no fibrosos (NFC) sobre los productos de la fermentación ruminal y la digestibilidad in vitro de la fibra detergente neutra (NDF) en cabras. Métodos: Se utilizó un arreglo factorial de 3 × 5, distribuidos en un diseño completamente aleatorizado con tres niveles de fNDF (100, 190 y 290 g/kg) y cinco niveles de NFC (350, 400, 450, 500 y 550 g/kg). El experimento se realizó in vitro. Se utilizaron dos cabras fistuladas en rumen como donantes de líquido ruminal. Resultados: La relacion entre fNDF y NFC afectó todos los parámetros ruminales estudiados (p<0,05). El aumento de los niveles de NFC en dietas con 100 y 290 g/kg de fNDF resultó en aumento lineal (p<0,05) de la concentración de amoníaco después de 48 h de fermentación. No hubo ajuste de modelos lineales (p>0,05) para valores de pH. Los ácidos grasos volátiles totales y sus proporciones molares individuales se afectaron (p<0,05) en todos los niveles de fNDF y NFC. La digestibilidad de NDF no fue afectada (p>0,05) por los niveles de fNDF ni NFC, con excepción de las dietas con 290 g/kg fNDF, que se ajustaron a un modelo cuadrático (p<0,05). Conclusión: La relación entre las concentraciones de fNDF y NFC afecta los productos finales de fermentación y la digestibilidad in vitro de NDF. Los niveles de NFC juegan un papel más consistente que fNDF en el ecosistema microbiano ruminal de la cabra durante la fermentación in vitro.
Resumo Antecedentes: Embora exista um compreensível entendimento do papel que a fibra dietética desempenha como nutriente e sua função durante a digestão em bovinos, o papel da digestão das fibras em caprinos não recebeu atenção semelhante. Objetivo: Avaliar os efeitos de diferentes relações da fibra em detergente neutro advindo de forragem (fNDF) e carboidratos não-fibrosos (NFC) sobre produtos da fermentação ruminal e digestibilidade in vitro da fibra em detergente neutro (NDF) em caprinos. Métodos: Utilizou-se um esquema fatorial de 3 × 5 distribuídos em um delineamento inteiramente casualizado com três níveis de fNDF (100, 190 e 290 g/kg) e cinco níveis de NFC (350, 400, 450, 500 e 550 g/kg). O experimento foi realizado in vitro. Duas cabras fistuladas no rúmen foram utilizadas como doadoras de líquido ruminal. Resultados: As relações entre fNDF e NFC impactaram todos os parâmetros ruminais estudados (p<0,05). O aumento dos níveis de NFC em dietas contendo 100 e 290 g/kg de fNDF resultou em um aumento linear (p<0,05) na concentração de amônia após 48 h de fermentação. Não houve ajuste de modelos lineares (p>0,05) para valores de pH. Os ácidos graxos voláteis totais e suas proporções molares individuais foram afetados (p<0,05) em todos os níveis de fNDF e NFC. A digestibilidade NDF não foi afetada (p>0,05) pelos níveis de fNDF e NFC, com exceção de dietas experimentais contendo 290 g/kg fNDF, que foram ajustadas a um modelo quadrático (p<0,05). Conclusão: A relação entre as concentrações de fNDF e NFC afeta os produtos finais de fermentação e a digestibilidade in vitro de NDF de dietas experimentais. Os níveis de NFC desempenham um papel mais consistente do que o fNDF no ecossistema microbiano ruminal de cabras durante a fermentação in vitro.
ABSTRACT
Silymarin is the standardized extract from Silybum marianum which consists mainly of flavonoids and polyphenols. It is highly regarded for its hepatoprotective ability. Silybin B is a flavonolignan and one of the active components of silymarin. The content of silybin B in various parts of S. marianum was analyzed by HPLC-UV. Results show that the extract of seeds contain the highest amount of silybin B (7.434 mg/g DW). The petioles of S. marianum showed a low content of silybin B. This study revealed that seeds of S. marianum contain high amount of silybin B and could be a good source of the compound.

GENERAL OBJECTIVE: To determine endometrial cancer risk among patients with abnormal uterine bleeding based on the International Endometrial Tumor Analysis (IETA) features.SPECIFIC OBJECTIVES: 1. To described the profile of patients with AUB suspected of having endometrial pathology; 2. To describe sonologic features of patients with AUB suspected of endometrial cancer using IETA features; and 3. To determine the association of a scoring system and endometrial cancer risk.METHODS: We prospectively studied 542 participants who came in the CWCU of CSMC with a diagnosis of AUB from July 1, 2016 to December 31, 2016. We excluded patients with endometrial thickness of less than 4 mm on gray-scale sonography, those with technical difficulties in assessing the endometrium such as in cases of very large myomas, absence of histopathological diagnosis, and those whose sampling was done as an office procedure. A total of 98 participants were included, 89 (90.8%) had benign pathologies and 9 (9.2%) were malignant. Patient characteristics including, age, gravidity, BMI, medical history, and endometrial assessment using IETA were tabulated with each characteristic given a score of 0-3 depending on the degree of risk factor. Percentages, Pearson Chi-square Test with corresponding P-value and ROC curve analysis were performed.RESULTS: The best predictors for endometrial cancer were age more than 50 years, nulligravid, BMI of more than 25, and presence of hypertension and diabetes mellitus. Sonographic features based on IETA showed an endometrial thickness of more than 20mm, irregular endometrial-myometrial junction, heterogenous endometrium, presence of multiple and large vessels on doppler analysis, contributed to endometrial cancer risk. These variables were used to create a scoring system with an area under the curve of 0.974 giving the best cut-off value of more than or equal to 9, with 100% sensitivity and 89% specificity.CONCLUSION: Among patients with abnormal uterine bleeding and endometrial thickness of more than 4mm, we can predict the risk for endometrial cancer and aid the clinician in decision making on who may be managed conservatively or aggressively based on the value obtained from the scoring system. The study, however, needs to be validated prior to use in clinical practice.

The content analysis of fatty acids in Perilla cultivars and commercial oils is conducted through gas chromatography with a flame ionization detector. Results show that Perilla cultivars, such as Deulsaem and Daesil, contain high amounts of α-linolenic acid (262.22 and 261.97 mg/g, respectively). Among commercial oils, Perilla oil contains a higher amount of α-linolenic acid (515.20 mg/g). Accordingly, α-linolenic acid is a major fatty acid of Perilla cultivars and oil. Therefore, Perilla cultivars could be used as a food supplement for nutritional and pharmaceutical purposes.
