Auditory enrichment with different genres of music for colony queens.

The aim was to determine changes in clinical parameters, glucose concentration, cortisol and behavior in colony queens in no music conditions compared with exposing to different genres of music. Mixed breed clinically healthy queens ( = 9) were used. Queens were studied under no music conditions (control=CON) and auditory enrichment: Soft Rock (M1), Motown (M2), Pop (M3), Frenchcore (M4) and music that was composed to be species-appropriate for cats (M5).

Vascular endothelial growth factor (VEGF) expression in histological endometritis in the bitch: An immunohistochemical study.

This work aimed to study the immunolocalization of vascular endothelial growth factor (VEGF) and its FLT-1 receptor (VEGFR1) in systemically healthy bitches with and without endometritis (END). Thirty-one uterine samples from mixed-breed, systemically healthy diestrous bitches, were included in the study. The bitches were divided into three groups after histological evaluation (normal endometrium [n = 8]; acute-END [n = 8]; subacute-END [n = 5]; chronic-END [n = 10]).

Serum progesterone concentration, volume, and apoptosis of corpora lutea in early, middle and late diestrus in the bitch.

The aim was to study number, volume, apoptosis of corpora lutea (CL), and serum P concentrations in early, middle, and late diestrus of dogs. Thirty-six bitches were ovari-hysterectomized (OVX): Early Diestrus (Group [G]1; OVX 20 days after end of estrus [DEH]); Mid-diestrus (GII; OVX between 21 and 40 days after DEH), and Late-diestrus (GIII; OVX between 41 and 60 days after DEH). Before OVX a blood sample was collected to quantify P.

Endometritis in the bitch: Immunohistochemical localization of cyclooxygenase 2.

Background: In several mammals, subfertility or infertility associated with endometritis was reported. Although there have been studies about endometritis in bitches, the pathophysiological mechanisms are not completely known.

Aim: This study aimed to evaluate the immunohistochemical expression of Cyclooxygenase 2 (COX2) in clinically healthy bitches with normal uterine tissue and bitches with endometritis.
