Platelet-Rich Plasma Proteome of Mares Susceptible to Persistent-Breeding-Induced Endometritis Differs from Resistant Mares.

Persistent-breeding-induced endometritis (PBIE) is the leading cause of subfertility and poor reproductive efficiency in mares. Platelet-rich plasma (PRP) treatment has been shown to mitigate PBIE, reduce uterine infections, and improve fertility in mares. However, the proteome of PRP in mares, particularly those susceptible to PBIE, remains unknown.

Exploring Canine Mammary Cancer through Liquid Biopsy: Proteomic Profiling of Small Extracellular Vesicles.

(Background). Canine mammary tumors (CMTs) have emerged as an important model for understanding pathophysiological aspects of human disease. Liquid biopsy (LB), which relies on blood-borne biomarkers and offers minimal invasiveness, holds promise for reflecting the disease status of patients.

Serum Extracellular Vesicles Cargo Approach in Bitches with Mammary Tumors.

This study investigated serum extracellular vesicles (EVs) in bitches with mammary neoplasms, in order to understand their size, shape, and concentration, as well as their association with tumor malignancy. Thirty bitches were categorized into control ( = 10), mammary tumor grades I and II (GI, = 13), and grade III (GII, = 7). Serum was separated from blood collected during mastectomy, and EVs were isolated using size exclusion chromatography.

Neonatal hypoglycemia in dogs-pathophysiology, risk factors, diagnosis and treatment.

Hypoglycemia is the most common metabolic alteration in the clinical routine of newborn dogs, acting as a predictor of mortality in these patients. The neonatal dog shows hepatic insufficiency and homeostatic mechanisms not yet fully developed, with limited glycogen reserves and limited capacity to perform glycogenolysis and gluconeogenesis. These physiological particularities make newborn dogs particularly susceptible to hypoglycemia when of fasting, even for short periods.

The interaction between seminal plasma, sperm, and endometrium in inter- and intra-species breeding in equids.

In Brief: In some instances, extra-species breeding in equids is more successful than intraspecies breeding; however, little is known about the immunomodulatory effect of donkey semen and seminal plasma on the mare's endometrium. This study compared the mare uterine inflammatory response during extra- and intraspecies breeding.

Abstract: Anecdotal experience suggests horse mares have less post-breeding inflammation and better fertility when bred with donkeys.

Symmetric dimethylarginine correlates with the urea, creatinine, potassium, and clinical scores in feline urethral obstructions.

Background: A urethral obstruction (UO) is an emergency commonly observed in male cats, which can result in significant clinical and laboratory alterations, leading to complications and death.

Objectives: This study aimed to correlate symmetric dimethylarginine (SDMA) with the urea, creatinine, potassium, and bicarbonate levels in cats with UO. In addition, the correlation between clinical score and time of obstruction was evaluated.

High depressive symptomatology reduces emotional reactions to pictures of social interaction.

Individuals with severe depressive symptoms present diminished facial expressions compared to healthy individuals. This reduced facial expression, which occurs in most depressive patients could impair social relationships. The current study sought to investigate whether pictures with social interaction cues could elicit different modulations of facial expressions and mood states in individuals with depressive symptoms compared to healthy individuals.

Proteomics approach reveals urinary markers for early pregnancy diagnosis in buffaloes.

This study aimed to compare urine proteomics from non- and pregnant buffaloes in order to identify potential biomarkers of early pregnancy. Forty-four females underwent hormonal ovulation synchronization and were randomly divided into two experimental groups: inseminated (n = 30) and non-inseminated (n = 14). The pregnant females were further divided into two groups: pregnant at Day 12 (P12; n = 8) and at Day 18 (P18; n = 8) post-ovulation.

Uterine secretome: What do the proteins say about maternal-fetal communication in buffaloes?

The aim was to compare the UF proteomics of pregnant and non-pregnant buffalo during early pregnancy. Forty-four females were submitted to hormonal estrus synchronization and randomly divided into two groups: pregnant (n = 30) and non-pregnant (n = 14). The pregnant group was artificially inseminated and divided into a further two groups: P12 (n = 15) and P18 (n = 15).

Hypoglycaemia management with a hypercaloric supplementation in neonatal puppies delivered by caesarean section.

There is a high perinatal mortality rate in dogs, estimated at 20%, and one of the leading causes of this rate is hypoglycaemia. Therefore, we aimed to evaluate the efficacy of a hypercaloric supplement containing vitamins and amino acids in newborn puppies presenting hypoglycaemia at birth. Ninety-nine pups were divided into four groups: normoglycaemic caesarean section (NORMOCS), hypoglycaemic caesarean section supplemented with the hypercaloric (SUPLCS), hypoglycaemic caesarean section supplemented with glucose (GLICCS) and eutocic delivery (EUT).

Ecological aspects of Pintomyia fischeri and Migonemyia migonei in municipalities with Canine Visceral Leishmaniasis, State of São Paulo, Brazil.

The objective was to study the composition of sand fly species, the seasonal activity of the dominant species and correlation with average rainfall, sex association of the dominant species with domicile habitats and analyze different landscape scenarios for the two study sites in the municipalities of Itapevi and Mogi of the Crosses. Sandflies were captured with CDC(s) traps installed in three households at each study site for a period of 24 hours, biweekly for two years. A total of 2970 specimens were collected.

Methods: Plan-Do-Study-Act cycles were performed to test the changes in drug preparation and administration processes via a nasoenteral feeding tube and to evaluate the outcome, process and balance measures. Statistical control charts were elaborated, and the bottom-up direct costing methodology was used to estimate the costs of the improvement programme.

Influence of culture conditions on the secretome of mesenchymal stem cells derived from feline adipose tissue: Proteomics approach.

This study aimed to describe the secretome of mesenchymal stem cells derived from feline adipose tissue (AD-MSCs) and compare the effects of different culture conditions on AD-MSC proteomics using a shotgun approach. Adipose tissue was collected from 5 female cats and prepared to culture. Conditioned media was collected at third passage, in which the cells were cultured under 4 conditions, normoxia with fetal bovine serum (N + FBS), hypoxia with FBS (H + FBS), normoxia without FBS (N - FBS), and hypoxia without FBS (H - FBS).

Can blood progesterone concentration identify non-pregnant buffaloes to support oestrous resynchronization?

This study compared the plasma progesterone concentrations from pregnant and non-pregnant buffaloes to identify non-pregnant females and submit cows earlier to oestrous resynchronization. Forty-four multiparous mix-breed Murrah buffaloes were selected for the study. The cows were subjected to hormonal oestrous synchronization and separated into 4 groups, P12 (pregnant, n = 8) and P18 (n = 8) at 12 and 18 days post-insemination; NP12 (non-pregnant, n = 7) and NP18 (n = 7) at 23 and 29 days after the onset of synchronization, respectively.

To identify the perception of health professionals regarding the concept of PC and their care experiences with this type of patient in a pre-hospital care (PHC) service in Brazil.

Methods: Study with a qualitative approach, of interpretative nature, based on the perspective of Ricoeur's Dialectical Hermeneutics.

Seminal Plasma Does Not Influence Canine Semen Stored at 5°C for Long-Term Conservation.

Seminal plasma has several components that protect the sperm cells and assist in the fertilization process. In contrast, the exact role carried out by seminal plasma during the cooling of canine semen remains controversial. Moreover, concerning the long estrus period, the possibility to store chilled semen at 5C for more than 72 hours and maintain good sperm quality for additional inseminations could increase fertilization rates.
