PERFIL BIOQUÍMICO SANGUÍNEO HEPÁTICO Y RENAL EN EL SAJINO (Tayassu tajacu) CRIADO EN CAUTIVERIO EN LA AMAZONÍA PERUANA

The objective of this study was to establish reference serum values for bilirrubin (total and direct), alanine amino transferase (ALT), aspartate amino transferase (AST), alkaline phosphatase, cholesterol, total protein, albumin, urea, and creatinine in healthy collared peccary (Tayassu tajacu) kept under captivity in the Amazonian jungle of Peru (Loreto, Iquitos). A total of 28 adult animals (14 males and 14 females) were used. Blood samples (7 ml) were collected from the safen vein. Serum values were: Total bilirrubin: 0.7 ± 0.2 mg/dl; direct bilirrubin: 0.2 ± 0.1 mg/dl; ALT: 26.5 ± 9.1 UI/l; AST: 15.9 ± 8.4 UI/l; alkaline phosphatase: 27.5 ± 15.5 UI/l; cholesterol: 94.4 ± 20.2 mg/dl; total protein: 8.5 ± 1.1 g/dl; albumin: 4.4 ± 0.5 g/dl; urea: 58.1 ± 11.1 mg/dl; and creatinine: 2.2 ± 0.5 mg/dl. It was concluded that serum values were similar to other results reported in the literature and without statistical differences due to sex.The objective of this study was to establish reference serum values for bilirrubin (total and direct), alanine amino transferase (ALT), aspartate amino transferase (AST), alkaline phosphatase, cholesterol, total protein, albumin, urea, and creatinine in healthy collared peccary (Tayassu tajacu) kept under captivity in the Amazonian jungle of Peru (Loreto, Iquitos).

Strongly coupled binuclear uranium-oxo complexes from uranyl oxo rearrangement and reductive silylation

The most common motif in uranium chemistry is the d0f0 uranyl ion [UO2]21 in which the oxo groups are rigorously linear and inert. Alternative geometries, such as the cis-uranyl, have been identified theoretically and implicated in oxo-atom transfer reactions that are relevant to environmental speciation and nuclear waste remediation. Single electron reduction is now known to impart greater oxo-group reactivity, but with retention of the linear OUO motif, and reactions of the oxo groups to form new covalent bonds remain rare. Here, we describe the synthesis, structure, reactivity and magnetic properties of a binuclear uranium–oxo complex. Formed through a combination of reduction and oxo-silylation and migration from a trans to a cis position, the new butterfly-shaped Si–OUO2UO–Si molecule shows remarkably strong UV–UV coupling and chemical inertness, suggesting that this rearranged uranium oxo motif might exist for other actinide species in the environment, and have relevance to the aggregation of actinide oxide clusters.JRC.E.6-Actinides researc

Workshops of the Sixth International Brain–Computer Interface Meeting: brain–computer interfaces past, present, and future

Brain–computer interfaces (BCI) (also referred to as brain–machine interfaces; BMI) are, by definition, an interface between the human brain and a technological application. Brain activity for interpretation by the BCI can be acquired with either invasive or non-invasive methods. The key point is that the signals that are interpreted come directly from the brain, bypassing sensorimotor output channels that may or may not have impaired function. This paper provides a concise glimpse of the breadth of BCI research and development topics covered by the workshops of the 6th International Brain–Computer Interface Meeting
