Factors related to the suppression of the antitumour immune response in female dogs with inflammatory mammary carcinoma.

Inflammatory mammary carcinoma (IMC), a neoplasia affecting women and female dogs, is considered an aggressive cancer with high metastatic potential and a low survival rate. Studies focused on the tumour microenvironment indicate that the aggressive behaviour of this tumour is primarily correlated with immunological factors as well as inflammation. The objective of this study was to analyse the possible strategies used by the tumour cells to suppress the immune response in female dogs with IMC.

Comparative analysis of origin and branches of phrenic nerve in the diaphragm of the crab-eating fox (Cerdocyon thous) and domestic dog (Canis lupus familiaris).

The crab-eating fox (Cerdocyon thous) is a canid widely distributed throughout South America, considered the only representative of the gender. There is a lack of information about anatomical aspects of the species, mainly regarded of nervous system anatomy. For clinical and surgical approaches of these animals, the domestic dog is adopted as anatomophysiological model.

Hyperresistinemia in Obese Female Dogs With Mammary Carcinoma in Benign-Mixed Tumors and Its Correlation With Tumor Aggressiveness and Survival.

Resistin is associated with metabolic, inflammatory, and neoplastic disorders, and is also considered a prognostic marker in human oncology. Canine mammary tumors have epidemiological, clinical, biological, and genetic characteristics similar to those of women and are proposed as a comparative study model. Here, we evaluate the serum levels of resistin in female dogs with or without mammary carcinoma in mixed tumors (CBMT) and its correlation with the proliferative potential of the tumor, obesity, and survival.

Lipid and metabolic profiles in female dogs with mammary carcinoma receiving dietary fish oil supplementation.

Background: Dyslipidemias induce angiogenesis and accelerate the development and in vitro growth of breast tumors. The aim of this study was to assess the lipid and metabolic profile of female dogs with mammary carcinomas and their correlations with body condition score and degree of tumor malignancy, as well as to study the effect of dietary fish oil supplementation on these animals.

Results: Overweight or obese dogs had more aggressive carcinomas and higher triglyceride (p = 0.

Correction to: Photography-based method for assessing fluorescein clearance test in dogs.

The original article [1] contained an error whereby the respective legends of Figs. 2 and 3 were mistakenly interchanged. This error has now been amended.

Photography-based method for assessing fluorescein clearance test in dogs.

Background: The fluorescein clearance test (FCT) provides insight into the tear film dynamics. The purpose of this study was to describe an inexpensive and practical method for assessing FCT in dogs, using photography and software analysis, and to assess the retention time of 1 vs. 2 eye drops on the canine ocular surface.

Morphological study of the eye and adnexa in capuchin monkeys (Sapajus sp.).

The objective of this study was to describe the anatomic and histologic features of the Sapajus sp. eye, comparing similarities and differences of humans and other species of non-human primates for biomedical research purposes. Computed tomography (CT) of adnexa, eye and orbit live animal, as well as formolized pieces of the same structures of Sapajus sp.

Cardiorespiratory effects of epidural anesthesia using lidocaine with morphine or dexmedetomidine in capuchin monkeys (Sapajus sp.) undergoing bilateral tubal ligation surgery, anesthetized with isoflurane.

Background: Epidural anesthesia is indicated to decrease other anesthetic requirements, prolong analgesia, and reduce side effects. In primates, its use has been scarcely described. The aim was to evaluate the cardiorespiratory effects of epidural anesthesia with lidocaine and dexmedetomidine (DEX) or morphine (MOR).

Ophthalmic diagnostic tests in captive red-footed tortoises (Chelonoidis carbonaria) in Salvador, northeast Brazil.

Purpose: The aim of this study was to establish normal ophthalmic parameters for select diagnostic tests in red-footed tortoises (Chelonoides carbonaria). A total of 52 animals, approximately 20-30 years old, were studied.

Method: Ophthalmic diagnostic tests included culturing of the normal conjunctival bacterial flora in summer and winter, evaluation of tear production using Schirmer tear test (STT) and endodontic absorbent paper point tear test in two different environmental temperatures (EAPPTT-1 at 32 °C and EAPPTT-2 at 18 °C), cytology of conjunctival cells, B-mode ultrasonography, measurement of palpebral fissure length (PFL), and applanation tonometry (in two different positions).

Ophthalmic diagnostic tests, orbital anatomy, and adnexal histology of the broad-snouted caiman (Caiman latirostris).

Purpose: The aim of this study was to establish normal ophthalmic parameters for selected diagnostic tests, and to describe the orbital anatomy and adnexal histology of the broad-snouted caiman.

Method: A total of 35 Caiman latirostris that were free of obvious ocular diseases were used to measure the parameters in this investigation. Ages ranged from 5 to 15 years.
