Hemoparasite occurrence and hematological/serum chemistry variations in Podocnemis vogli turtles: A comparative analysis between wild-residing infected specimens and captive non-infected counterparts.

Reptiles show a high occurrence of hemoparasites in the wild; however, little is known about the impact of such infections on their hosts' physiology and health status. Podocnemis vogli is an ancient turtle distributed in South America, frequently infected by blood parasites. Specifically, we analyzed the hematological and serum chemistry parameters of 78 wild turtles.

Hematology, Biochemistry Reference Intervals, and Morphological Description of Peripheral Blood Cells for a Captive Population of in Colombia.

The Orinoco crocodile (, Graves, 1918) is the most threatened crocodilian of South America. There is only scarce information available about the physiology of this neotropical crocodile. This study aimed to propose baseline hematological and biochemistry reference data and intervals and a morphological description of the peripheral blood cells of captive .

The Ratón Pérez collection: Modern deciduous human teeth at the Centro Nacional de Investigación sobre la Evolución Humana (Burgos, Spain).

Objectives: The aim of this report is to present the large deciduous tooth collection of identified children that is housed at the National Research Center on Human Evolution (CENIEH) in Burgos, Spain.

Methods: Yearly, members of the Dental Anthropology Group of the CENIEH are in charge of collecting the teeth and registering all the relevant information from the donors at the time of collection. In compliance with Spanish Law 14/2007 of July 3, 2007, on Biomedical Research (BOE-A-2007-12945), all individuals are guaranteed anonymity and confidentiality.

[Renal cancer].

Objectives: This study was carried out 1) to analyze the growth and clinical manifestations of renal adenocarcinoma; 2) to determine the presence of tumor, its malignant nature, size, local extent or distant spread and route of dissemination according to the imaging methods utilized, and 3) to determine the accuracy of the different imaging procedures, such as IVP, US, CT, and MRI, in staging renal adenocarcinoma. These objectives attempted to provide answers to the following questions: a) Are there currently substantial changes in the biological behavior of renal adenocarcinoma?, b) Does the route of tumor dissemination (direct infiltration through the capsule, lymphohematogenous, cancer embolus carried by the bloodstream to a distant location) affect the rate of progression to stages III and IV?, and c) What are the most relevant findings of the imaging methods that aid in determining the extent of the renal tumor?

Methods: 106 renal masses were evaluated; of these, 93 were renal adenocarcinomas. The diagnosis, clinical evaluation and preoperative staging were based on the clinical history, physical examination, symptoms and imaging methods (IVP, US, CT, and MRI) to assess renal morphological changes, presence of calcifications, mass effect, tumor mass ultrasound characteristics, densitometry or MR signal pattern, perinephric fat involvement, venous vasculature, involvement of renal fascia, locoregional lymph nodes or metastasis and distant neoplastic changes.
