Abstract
The objectives of this study were: a) To report anti-Müllerian hormone (AMH) serum concentrations in neonatal, pre and postpubertal female cats. b) To establish the relationship between serum AMH with either age and estrous cycle c) To correlate the total number of different ovarian follicle types with AMH in adult queens. A single blood sample was collected from 10 neonates (including 5 male), 15 prepubertal and 48 postpubertal female cats to measure AMH. Eight, 10, and 18 of this latter group were in follicular (FP), luteal phase (LP), and anestrus (AN), respectively. The total number of each follicle type was histologically counted using the Gougeon and Chainy (1987) formula in a subgroup of 10 adult queens. Overall AMH mean of these the female cats was 6.31 ± 0.54 ng/mL. The neonatal females had lower AMH serum concentrations than their male littermates (2.56 ± 0.49 vs. >23 ng/mL; P < 0.01). Concentrations were also higher in prepubertal than in neonatal and postpubertal cats (11.79 ± 1.36 vs. 2.56 ± 0.49 vs. 4.87 ± 0.38 ng/mL; P < 0.01). Queens below 12 mo of age had the highest AMH levels (10.41 ± 1.16; P < 0.01). Age was inversely correlated with AMH (r = -0.5; P < 0.01). Animals in FP had lower AMH concentrations than AN females (2.51 ± 0.33 vs. 5.46 ± 0.76 ng/mL; P < 0.05). No difference in the total number of each follicle type were found between either ovary (P > 0.05). A high correlation was only found between small antral follicles and AMH concentrations (r = 0.85; P < 0.01). It was concluded, that AMH can provide an indirect, reliable marker for the assessment of ovarian follicle size and functionality. Age as well as pubertal state should be considered when evaluating AMH concentrations in this species.

Abstract
Two alkalinizing mechanisms coexist in cardiac myocytes to maintain intracellular pH: sodium/bicarbonate cotransporter (electroneutral isoform NBCn1 and electrogenic isoform NBCe1) and sodium/proton exchanger (NHE1). Dysfunction of these transporters has previously been reported to be responsible for the development of cardiovascular diseases. The aim of this study was to evaluate the contribution of the downregulation of the NBCe1 to the development of cardiac hypertrophy. To specifically reduce NBCe1 expression, we cloned shRNA into a cardiotropic adeno-associated vector (AAV9-shNBCe1). After 28 days of being injected with AAV9-shNBCe1, the expression and the activity of NBCe1 in the rat heart were reduced. Strikingly, downregulation of NBCe1 causes significant hypertrophic heart growth, lengthening of the action potential in isolated myocytes, an increase in the duration of the QT interval and an increase in the frequency of Ca2+ waves without any significant changes in Ca2+ transients. An increased compensatory expression of NBCn1 and NHE1 was also observed. We conclude that reduction of NBCe1 is sufficient to induce cardiac hypertrophy and modify the electrical features of the rat heart.

Abstract
The objectives of this study were to evaluate the uterine artery blood flow during the second half of normal pregnancy in small breed dogs and to determine the RI reference values of this artery in these bitches. Fifty-two, 1.5-6.5 kg, purebred healthy pregnant bitches were included in this study. Doppler ultrasonographic examinations of the uterus were performed every 10 days from Day 30 of the estrous cycle to parturition. Peak systolic velocity (PSV) and end diastolic velocity (EDV) of the uterine artery were measured while RI [(PSV-EDV)/PSV] was automatically calculated. Values of PSV, EDV and RI were analyzed by repeated measures ANOVA followed by Tukey test using age, body weight, litter size and parity as covariates. Resistance index reference ranges were constructed by regressing this index on gestational age. Equation of the polynomial regression curves was used to calculate the mean, 95th and 5th centiles for each gestational age (GA). A gradual increase of PSV (P < 0.01) and EDV (P < 0.01) and a decrease in RI (P < 0.01) were found throughout the study period. PSV and EDV were influenced by litter size (P < 0.05), while RI was not. None of the Doppler parameters were influenced by age, body weight or parity. A second-degree polynomial described the relationship between RI of uterine artery and GA in the different time points: [RI = 0.993 + 8.4x10-5 x GA2- 0.0117 x GA]. It is concluded that uterine artery blood flow progressively increased throughout normal pregnancy in small breed bitches. In addition, reference ranges of uterine artery RI were 0.64-0.79, 0.57 to 0.75, 0.53 to 0.71 and 0.52 to 0.66 on Days 30, 40, 50 and 60 of gestation, respectively.

Abstract
The aim of this study was to evaluate echocardiographic and electrocardiographic parameters during the normal canine postpartum period. Twenty clinically healthy pregnant bitches of toy breeds (11 Miniature poodles, five Yorkshire terriers, two Maltese terriers and two Bichons Frises) were evaluated on days -3, 3, 10, 17, 24, 38, 52 and 80 relative to parturition (day 0). During the first postpartum week, the width of the interventricular septum in systole, the shortening fraction and the left atrium size decreased, while the left ventricle internal diameter in systole and end systolic stress increased. There were progressive decreases in the velocity of circumferential fibre shortening, stroke volume, cardiac output, and mitral E and A wave values. Systolic blood pressure increased markedly during the first postpartum week to gradually increase thereafter. Heart rate and corrected QT interval progressively decreased, while P wave amplitude increased. QRS complex amplitude decreased in the second week after parturition and then increased during the following weeks. In conclusion, there were changes in systolic function and some structural adaptive changes in the bitch during the first 80days postpartum. In addition, maternal heart rate and corrected QT interval decreased, while P wave and QRS amplitudes increased.

Abstract
The aim of this study was to describe resistance index (RI) and systolic/diastolic ratio (S/D ratio) of uterine and umbilical arteries in an experimental model of abnormal pregnancy in felids. On days 30 to 35 (32 ± 2.9) after mating, 20 domestic short-hair pregnant queens were randomly assigned to one of the following treatment groups: a treated group (TG; n = 8), which received 10 mg/kg of aglepristone subcutaneously twice, 24 hours apart, and a control nontreated group (CG; n = 12). M-mode and Doppler ultrasonographic evaluations were performed at the initiation of the treatment (Day 0) and then every other day during 8 days. In both groups, uterine and umbilical arteries were evaluated by Doppler ultrasound, whereas fetal heart rate was assessed by M-mode ultrasound. Resistance index of uterine artery augmented in TG from Day 2 onward, conversely it decreased in CG (P < 0.01). On Day 8, RI values were 0.64 ± 0.05 vs 0.37 ± 0.01 for TG and CG, respectively. Additionally, S/D ratio of the same artery presented an increase in TG, whereas this ratio diminished in CG (P < 0.01). On Day 8, this parameter showed values of 2.98 ± 0.4 vs 1.62 ± 0.06 for TG and CG, respectively. Resistance index of umbilical artery remained almost unchanged in TG from Day 6 onward, whereas it progressively decreased in CG throughout the course of the study (P < 0.05). On Day 8, RI were 0.89 ± 0.04 and 0.82 ± 0.01, for TG and CG, respectively. Furthermore, on Day 8, S/D ratio of umbilical artery progressively diminished in CG but not in TG (P < 0.01), being 14.7 ± 9.1 vs 5.9 ± 0.3 for TG and CG, respectively. Fetal heart rate was higher in TG than in CG (P < 0.05). Group differences in Doppler parameters appeared on Day 2, when the other clinical or ultrasonographic signs were still absent. It is concluded that blood flow of the uterine and umbilical arteries differed between these normal and abnormal gestations predicting an adverse obstetric outcome.

Abstract
Doppler ultrasound is a useful diagnosis tool to evaluate uterine blood flow in different canine reproductive states. The aim of this study was to describe and compare uterine blood flow in bitches suffering from cystic endometrial hyperplasia (CEH) and CEH-pyometra complex (CEH-P). Ninety diestrous bitches were clinically, hematologically, and ultrasonographically classified into four groups: (1) clinical signs, leukocytosis, CEH, and uterine luminal contents (CEH-P, n = 31); (2) asymptomatic bitches with CEH and uterine contents (CEH-C, n = 15); (3) asymptomatic bitches with CEH without uterine contents (CEH, n = 16); and (4) normal diestrous bitches (ND, n = 28). The widest cross-sectional diameter and uterine wall thickness (W) of uterine horns were measured using two-dimensional ultrasound. Peak systolic velocity and end diastolic velocity of uterine arteries were measured by Doppler ultrasound in all the bitches. Peak systolic velocity and end diastolic velocity were higher in CEH-P than in CEH-C, CEH, and ND (P < 0.01); although both parameters did not show differences among the latter three groups (P > 0.1). Conversely, resistance index (RI) reported lower values in CEH-P than that in the other three groups (P < 0.01), being ND higher (P < 0.01) than both CEH-C and CEH which did not differ between themselves (P > 0.1). When all the bitches were considered, correlation between RI and cross-sectional diameter was r = -0.69 (P < 0.01) and between RI and uterine wall thickness was r = -0.02 (P > 0.1). It is concluded that the uterine artery blood flow velocity of bitches suffering from pyometra was higher, not only from normal bitches, but also from females with endometrial hyperplasia. Furthermore, endometrial hyperplasia, accompanied or not by luminal contents, had a higher blood flow velocity than normal uterus. Hemodynamic parameters appear as useful markers to differentiate uterine pathologic conditions.

Abstract
The aim of this study was to describe Doppler parameters of uterine, umbilical, fetal abdominal aorta, fetal renal and fetal internal carotid arteries, as well as fetal heart rate (FHR), during normal feline gestation. Fifteen, 1-4 years of age, weighing 2.5-3.9kg, domestic short-hair pregnant queens, which were born in our institutional cat colony were included in this study. Color and pulsed-wave Doppler evaluations of uterine arteries were performed every 10 days (Day 0, 10, 20, 30, 40, 50, 60) from mating. Fetal Doppler and M-mode ultrasonography were performed to assess umbilical, fetal abdominal aorta, fetal renal, fetal internal carotid arteries and FHR. Both peak systolic velocity (PSV) and end diastolic velocity (EDV) of uterine artery increased up to parturition (P<0.01), while resistance index (RI) decreased from Day 10 onwards (P<0.01). From Day 40 onwards, RI of umbilical artery diminished, while PSV and EDV augmented (P<0.01). Fetal abdominal aorta (P<0.01), renal (P<0.01) and internal carotid (P<0.01) arteries diminished their RI from Days 40, 60 and 40 onwards, respectively. Both PSV and EDV of these three arteries increased progressively. Fetal heart rate was first registered on Day 20 when it began to increase up to Day 40 and then diminished to the end of gestation (P<0.01). It is concluded that blood flow of uterine, umbilical, fetal abdominal aorta, fetal renal and fetal internal carotid arteries progressively increased during normal feline pregnancy, while FHR rose to mid gestation and then decreased up to parturition.

Abstract
The aim of this study was to describe the changes of uterine artery, umbilical artery and fetal abdominal aorta, renal and internal carotid arteries blood flow in abnormal canine pregnancy. Twenty-two, Brucella-negative pregnant bitches were retrospectively classified into abnormal (which had either interrupted their pregnancy between days 52 and 60 or had perinatal death >60% of the litter; n=11) and normal (which had delivered healthy puppies at term; n=11). In all the animals, color and pulsed-wave Doppler examinations of uterine artery were conducted every 10 days from Day 20 to 50 from estimated luteinizing hormone peak. Doppler ultrasonography was also conducted in the fetuses to assess umbilical artery, abdominal aorta, renal and internal carotid arteries from Day 40 to 60 of gestation. Throughout the study, resistance index (RI) of uterine, umbilical and fetal renal arteries decreased up to -15% compared to -36% (P<0.01), -11% compared to -23% (P<0.05) and 2% compared to -13% (P<0.05), respectively in the abnormal and normal bitches. Fetal abdominal aorta and internal carotid did not differ between groups (P>0.05). It is concluded that in dogs, uterine artery, umbilical artery and fetal renal artery RI differ between normal and abnormal gestation being useful for the prediction of adverse obstetric outcome.

Abstract
OBJECTIVES To determine whether the incidence of inflammatory bowel disease (IBD) has changed in our area and whether it has been influenced by the growing immigrant population. POPULATION AND METHODS From 2000 to 2009, a prospective population-based study was conducted in the population aged over 15 years old and was compared with a study carried out from 1994 to 1998 in the health area of Campo Arañuelo. The distribution of Crohn's disease (CD), ulcerative colitis (UC) and age and sex were analyzed and compared with European rates for the standard population, both for the total population and for the local population. RESULTS From 2000 to 2009, IBD was diagnosed in 73 patients (36 men and 37 women). CD was diagnosed in 25 patients (34.2%), UC in 46 (63.0%) and there were two cases (2.8%) of indeterminate colitis (IC), which were excluded from the analysis. The mean annual incidence of CD was 5.70 per 100,000 inhabitants (5.79 in men and 5.60 in women). The annual incidence of UC was 11.47 per 100,000 inhabitants (10.79 in men and 12.17 in women). The incidence of UC was significantly higher than that of CD. The UC/CD ratio was 1.87. The mean age of patients with CD was 31.44 ± 15.81 years (range: 15 to 79 years), which was significantly lower than that for patients with UC: 43.26 ± 18.63 years (range: 15 to 85 years), with a difference of 11.82 years (confidence interval [CI]: 3.05-20.59 years). No immigrants were diagnosed. The incidence related to the total population aged between 15 and 64 years old was 5.74 per 100,000 inhabitants per year (95% CI: 3.43-8.04) in CD and 9.48 per 100,000 inhabitants per year (CI: 5.63-13.32) in UC. The incidence related to the local population aged between 15 and 64 years old was 5.90 per 100,000 inhabitants per year (95% CI: 3.52-8.28) in CD and 9.75 (CI: 5.80-13.70) in UC. CONCLUSIONS The incidence of UC in our area is one of the highest in Spain. Although this incidence is lower than that from 1994 to 1998, this decrease is not significant. The number of CD cases has not increased. Both diseases affect men and women equally. CD is diagnosed in earlier ages than UC. Exclusion of immigrants from the study increases these rates but not significantly.

Abstract
Two experiments were conducted to investigate the effects of the GnRH antagonist acyline (330 microg/kg, given sc) on ovarian follicular development and ovulation, as well as on pregnancy maintenance in domestic cats. In the first experiment, seven queens in proestrus (total of 24 proestrus periods), were randomly assigned to treatment with either acyline (ACY; n=17) or a placebo (PLC; n=7). All queens were mated with a fertile tomcat. In the ACY and PLC groups, cessation of estrus occurred (mean+/-SEM) 7.0+/-1.3 and 7.0+/-1.7 d after treatment (P>0.1), ovulation occurred in 2 of 17 and all seven estrus periods (P<0.05), and pregnancy rates were 1 of 16 and 7 of 7 (P<0.05), respectively. In the ACY and PLC groups, intervals from treatment to the onset of the ensuing proestrus were 18.4+/-1.7 and 120+/-17.2 d. In the second experiment, 14 pregnant queens were randomly allocated, according to their mating date, to treatment with acyline in early pregnancy (from 20 to 25 d, n=3), mid pregnancy (from 26 to 45 d; n=4), late pregnancy (> 45 d; n=3), or injection of a placebo in early (n=1), mid (n=2), or late pregnancy (n=1). Ultrasonographic assessments of the uterus were done every second day for 2 wk post treatment, and serum progesterone (P(4)) concentrations were determined before treatment, and at 7 and 14 d after treatment. No pregnancies were prematurely terminated and post-treatment P(4) concentrations did not differ among treatment groups (P>0.1). In conclusion, in the domestic cat, GnRH withdrawal by acyline prevented ovulation when given in early follicular phase (proestrus), but did not significantly affect luteal function during pregnancy.

Abstract
Cystic fibrosis (CF) is associated with deficiencies in certain essential fatty acids. These deficiencies have been studied in plasma, red blood cells, and mucus and were previously thought to be a result of malnutrition or malabsorption. More recent studies have indicated that these deficiencies are independent of nutritional status. However, these studies examined fatty acids in plasma but not in CF-regulated tissues. In the pancreas, lungs, and ileum of CF knock-out mice, membrane-bound arachidonic acid levels have been shown to be increased while docosahexaenoic acid levels are decreased. This lipid abnormality is reversed following oral administration of docosahexaenoic acid (DHA). In addition, DHA therapy reverses the increased neutrophil infiltration in the lungs of CF knock-out mice. Further studies are required to determine the mechanism by which CF gene mutations lead to this lipid abnormality.

Abstract
Nutrition has an important role in the management of chronic pancreatitis (CP), with two main goals for treatment of patients. The first goal is to provide optimal nutrition support and the second is to decrease pain by minimizing stimulation of the exocrine pancreas. Because cholecystokinin (CCK) stimulates secretion from the exocrine pancreas, one approach is to decrease CCK levels through modulation of diet. If postprandial pain is a limiting factor, alternative enteral therapies that minimally stimulate the pancreas may be beneficial. Nutritional counseling, antioxidants, and pancreatic enzymes may play a role in effective management of CP as well. In addition, because idiopathic CP is associated with cystic fibrosis gene mutations, therapies directed toward cystic fibrosis may also benefit these patients.
