The aim of this study was to evaluate the superovulatory and embryonic response in alpacas with equine chorionic gonadotropin (eCG) according to the number of follicles recruited >3 mm in the follicular wave (FW). Twenty-six alpacas from the CIP “Chuquibambilla”, Universidad Nacional del Altiplano, Puno, Peru, were selected and distributed into two experimental groups: GE01 (n=15 alpacas) with less than three follicles >3 mm and GE02 (n=11 alpacas) with more from four follicles >3 mm in diameter to follicular recruitment post-induction of ovulation by a follicle >7 mm with 0.0042 mg of buserelin acetate (BA). Both groups were evaluated by ultrasound every other day until the beginning of the third follicular wave. Subsequently, females with follicles >7 mm were induced to ovulate with BA (day 0), ovulation was verified at 36 h and 700 IU of eCG was administered. On day...

The study aimed to characterize the follicular emergence and determine the repeatability of the follicular wave in alpacas. For this, 34 female alpacas were selected and induced to ovulation by parenteral application of buserelin acetate (day 0). Two days after the hormonal stimulation, individual follicular development was recorded by counting the total number of antral follicles >3 mm in both ovaries. For this, an inter-daily transrectal ultrasound follow-up was done for 60 days. It was determined that the emergence of the follicular wave occurred on day 4.5 ± 1.4 (range 2-8). The number of antral follicles (NAF) >3 mm during three consecutive follicular emergencies was 2.8 ± 1.3 (range 1-8). Despite having a great similarity (p>0.05) in the NAF >3 mm during three successive follicular emergencies there is a significant difference in the average number of emerging follicl...

The aim of this study was to determine the concentration of glucose, total proteins, albumin, cholesterol and triglycerides in the follicular fluid during the three stages of follicular development in alpacas. Twenty-seven animals from CIP Chuquibambilla, National University of the Altiplano, Puno, Peru were used. The alpaca ovaries were checked by an Aloka SSD 500 ultrasound and a 7.5 MHz linear transducer. The animals were subjected to a follicular wave synchronization procedure in the presence of a follicle >7 mm. On day 9 of the synchronization the animals were distributed according to the stage of the follicular wave in three groups: G1, follicle >7 mm in the growing stage; G2, follicle >7 mm in the static stage; G3, follicle >7 mm in the regression stage. The follicular fluid was aspirated from the dominant follicle with the indicated ultrasound and a 5.0 MHz transvagin...

El presente trabajo tuvo como objetivo caracterizar la emergencia folicular y determinar la repetibilidad de la onda folicular en alpacas. Para ello, 34 hembras alpacas fueron seleccionadas e inducidas a ovulación mediante la aplicación parenteral de acetato de buserelina (día 0). Dos días después del estímulo hormonal, se registró el desarrollo folicular individual a partir del conteo del número total de folículos antrales >3 mm en ambos ovarios. Para esto, se hizo un seguimiento ecográfico transrectal inter diario por 60 días. Se determinó que la emergencia de la onda folicular se produjo el día 4.5 ± 1.4 (rango 2-8). El número de folículos antrales (NFA) >3 mm durante tres emergencias foliculares consecutivas fue de 2.8 ± 1.3 (rango 1-8). A pesar de haber una gran similitud (p>0.05) en el NFA >3 mm durante tres emergencias foliculares sucesivas existe una ...

Osteogenesis imperfecta is considered a rare genetic condition which is characterized by bone fragility. In 85% of cases, it is caused by mutations in COL1A1 and COL1A2 genes which are essential to produce type I collagen. We report the case of a female neonate delivered to a 27-year-old women at San Bartolomé Teaching Hospital with a family history of clavicle fracture. A prenatal control with ultrasound was performed to the mother at 29 weeks. A fetus with altered morphology and multiple fractures was found. Therefore, a prenatal diagnosis of osteogenesis imperfecta was performed. The neonate was born with a respiratory distress syndrome and an acyanotic congenital heart disease. Therefore, she remained in NICU until her death. We highlight the importance of prenatal diagnosis, genetic counseling and a multidisciplinary evaluation in this type of pathologies and report a new probably ...
