1. 18F-FDG PET/CT in pure testicular Yolk Sac Tumor in adult
ABSTRACT Purpose: Epidemiological studies reported conflicting results about preoperative hydronephrosis in upper tract urothelial carcinoma (UTUC). This study aimed to investigate the association between preoperative hydronephrosis and pathologic features and oncologic outcomes in patients with UTUC treated by radical nephroureterectomy (RNU). Materials a

2. Effect of In Ovo Feeding of L-Glutamine to Chick Embryos
ABSTRACT In ovo feeding (IOF), injecting nutrients into the amnion of the avian embryo may enhance hatchability, gastrointestinal development and serum metabolism changes. This hypothesis was evaluated with 5 IOF solutions containing L-glutamine. Were used 315 fertile Rhode Island Red eggs were used (breeders with 32-weeks). The experimental design was compl

3. Germ Cell Tumors in Dysgenetic Gonads
This review describes the germ cell neoplasms that are malignant and most commonly associated with several types of gonadal dysgenesis. The most common neoplasm is gonadoblastoma, while others including dysgerminomas, yolk-sac tumors and teratomas are rare but can occur. The purpose of this review is to evaluate the incidences of these abnormalities and th

4. Macroscopic embryonic development of Guinea fowl compared to other domestic bird species
ABSTRACT Since few studies have addressed the embryonic development of Guinea fowl (Numida meleagris), the objective of the present study was to evaluate its embryonic development in the Cerrado region of Brazil and compare the results to published descriptions of the embryonic development of other domestic bird species. The commercialized weight for Guinea

5. Progesterone’s Serum Level and a New Ultrasonographic Parameter in the First Trimester Pregnancy - Prognostic Factors for Embryonic Demise
Abstract Objective The etiology of embryonic demise is multifactorial, with chromosomal abnormalities being the most common (40%). The purpose of the present study is to evaluate the correlation between a serum biomarker, progesterone, and an ultrasonographic parameter, the distance between yolk sac and embryo (DYSE) in assessing the prognosis of pregnancy

6. Post-hatch fasting and infectious bronchitis vaccination affect growth, gastrointestinal development, and morphometric parameters of the small intestine of broiler breeders up to three weeks of age
ABSTRACT The influence of fasting and vaccination against infectious bronchitis (IB) on growth, gastrointestinal development, and morphometric parameters of the small intestine of newborn broiler breeders was investigated. Weight gain (WG), feed conversion ratio (FCR), gastrointestinal visceral growth, residual yolk sac, and morphometric parameters of the sm

7. Effects of White Roman gosling quality on their growth parameters, intestinal villus morphology, blood biochemistry, and nonspecific pathological lesions
ABSTRACT The purpose of this study was to investigate the effects of gosling quality on their growth parameters, intestinal villus morphology, blood biochemistry, and nonspecific pathological lesions from 0 to 4 weeks old. Seventy-two goslings were randomly distributed into 12 pens, with each pen containing three males and three females in a completely rando

8. Effect of Hatching Time on Yolk Sac Percentage and Broiler Live Performance
ABSTRACT This study investigated the effects of broiler chick hatching time on the percentage of the yolk sac and subsequent broiler live performance. Broiler hatching eggs were obtained from a commercial flock at 55 wk of age and were stored for 2 d at 18°C and 75% relative humidity (RH) prior to incubation. Chicks were identified as hatching Early (471-47

9. Larval development of the Mexican Snook, Centropomus poeyi (Teleostei: Centropomidae)
ABSTRACT We document for the first time the early ontogeny of Centropomus poeyi based on captive raised material representing 0-19 days posthatch (dph). The achievement of early developmental landmarks (i.e., yolk-sac depletion, flexion, development of fins) and changes in pigmentation are described (1.4 mm NL-10.6 mm SL; 0-19 dph) and documented for a subse

10. Developmental Toxicity of (4S)-2- (4-hydroxy-3-methoxyphenyl) thiazolidine-4-carboxylic acid in Zebrafish ( Danio rerio )
ABSTRACT (4S)-2-(4-hydroxy-3-methoxyphenyl)thiazolidine-4-carboxylic acid is new synthesized substance obtained from cysteine and valine. Thiazolidine derivates have important biological responses so scientists work intensively on these compounds in recent years. It is obvious that thiazolidine contained compounds will be used in future in the pharmaceutical

11. Robot - assisted laparoscopic retroperitoneal lymph node dissection in testicular tumor
ABSTRACT Introduction and objective Retroperitoneal lymph node dissection (RPLND) is indicated for patients with non-seminomatous germ cell tumor (NSGCT) with residual disease after chemotherapy. Although the gold standard approach is still the open surgery, few cases of robot-assisted laparoscopic RPLND have been described. Herein, we aim to present the s

12. Pure Yolk sac presenting with inferior vena cava thrombus extending from bilateral external iliac veins to hepatic vein
ABSTRACT Introduction: Vena cava thrombus is an extremely rare complication of testicular tumors. We report on an unusual case of testicular tumor presenting with inferior vena cava thrombus extending from the left spermatic and bilateral external iliac veins to the hepatic vein. Case report: A-35-year old man presented with a 6-month history of left scrot
