1. Intraoperative frozen section performance for thyroid cancer diagnosis
ABSTRACT Objective: A primary medical relevance of thyroid nodules consists of excluding thyroid cancer, present in approximately 5% of all thyroid nodules. Fine-needle aspiration biopsy (FNAB) has a paramount role in distinguishing benign from malignant thyroid nodules due to its availability and diagnostic performance. Nevertheless, intraoperative frozen

2. Malignancy Rate in Thyroid Nodules with Atypia or Follicular Lesion of Undetermined Significance
Abstract Introduction Atypia of undetermined significance (AUS) or follicular lesion of undetermined significance (FLUS) is one of the six diagnostic categories of the Bethesda System for Reporting Thyroid Cytopathology. The prevalence of malignancy among Bethesda category III cytology is variable, ranging from 5% to 37% in the literature. Objective To d

3. Effect of recombinant bovine somatotropin (rbST) treatment on follicular population and development in non-lactating dairy cows
Abstract The aim of this study was to evaluate the long-term effects of recombinant bovine somatotropin (rbST) on follicle population and ovulatory follicle development in non-lactating dairy cows. Twenty-one Jersey cows were allocated in rbST (n=11) or control (n=10) groups. On day -60, cows in rbST group received 500 mg of somatotropin (s.c. Lactotropin®,

4. In vitro embryo production in buffaloes: from the laboratory to the farm
Abstract Transvaginal follicular aspiration technique together with in vitro embryo production are the biotechnological alternatives currently available to support genetic improvement breeding programs in buffalo species. However, aspects related to animal management, lack of knowledge of the metabolic needs and biochemical peculiarities of gametes and embry

5. Effect of Rolipram on in vitro maturation, gene expression and embryonic development in bovines
RESUMO O objetivo deste trabalho foi avaliar o efeito do rolipram durante a maturação de oócitos bovinos, expressão gênica e embriões produzidos in vitro. Os ovários bovinos foram coletados no matadouro. Os COCs foram selecionados e divididos em cinco grupos: controle 0 tempo; controle: MIV por 24 horas; tratamentos rolipram com bloqueio MIV por 24 ho

6. Malignancy rates for Bethesda III subcategories in thyroid fine needle aspiration biopsy (FNAB)
OBJECTIVES: Most thyroid diseases are nodular and have been investigated using ultrasound-guided fine needle aspiration biopsy (FNAB), the reports of which are standardized by the Bethesda System. Bethesda category III represents a heterogeneous group in terms of lesion characteristics and the malignancy rates reported in the literature. The objective of th

7. Increasing diagnostic effectiveness of thyroid nodule evaluation by implementation of cell block preparation in routine US-FNA analysis
ABSTRACT Objective Ultrasound-guided fine-needle aspiration (US-FNA) biopsy has proven to be an accurate and efficient tool in thyroid nodule evaluation. We evaluated whether cell block adds to the diagnostic accuracy of US-FNA. Subjects and methods Three hundred twenty-eight consecutive patients underwent US-FNA, cytology and cell block evaluation. Six

8. Association of recombinant bovine somatotropin (rBST) with equine chorionic gonadotropin (eCG) on antral follicle count and oocyte production in Holstein and Tabapuã heifers
The objective of this study was to investigate whether the use of rbST and eCG prior to ultrasound-guided follicular aspiration (OPU) improves oocyte yield and quality in Tabapuã and Holstein heifers. The study was conducted in two phases, 20 days apart, in a change-over design. The dominant follicle was ablated two days (D-2) before two treatments: stimula

9. Follicular dynamics and production of oocytes in young Nellore heifers with energetic supplementation
To verify the effects of energy supplementation and fat on follicular dynamics, metabolic profile and the production of oocytes, 15 young heifers (Bos taurus indicus) with an average age of 14 months and with an initial weight of 256.35 kg were assigned to two treatments according to weight and follicular population as evaluated by ultrasonography: in T1 (1.

10. Protocolos hormonais de preparação de doadoras bovinas para produção de embriões in vitro / Different protocols to bovine donor preparation for in vitro embryo production
Efficiency of in vitro bovine embryo production has been affected by low quantity and quality of recovered oocytes from ultrasound-guided follicular aspiration (OPU). The objective of this study was to evaluate the effect of different synchronization of follicular wave protocols in the production of oocytes and embryos in vitro, of Bos taurus taurus and Bos

12. Diagnóstico de lesões da tireóide pela espectroscopia de absorção no infravermelho por transformada de Fourier-FTIR / Thyroid lesions diagnosis by fourier transformed infrared absorption spectroscopy (FTIR)
Thyroid nodules are a common disorder, with 4-7% of incidence in the Brazilian population. Although the fine needle aspiration (FNA) is an accurate method for thyroid tumors diagnosis, the discrimination between benign and malignant neoplasm is currently not possible in some cases with high incidence of false negative diagnosis, leading to a surgical interve
