Life, the universe, and everything: An education outreach proposal to build a traveling astrobiology exhibit

Astrobiology is a transdisciplinary field with extraordinary potential for the scientific community. As such, it is important to educate the community at large about the growing importance of this field to increase awareness and scientific content learning and expose potential future scientists. To this end, we propose the creation of a traveling museum exhibit that focuses exclusively on astrobiology and utilizes modern museum exhibit technology and design. This exhibit (the Astrobiology Road Show), organized and evaluated by an international group of astrobiology students and postdocs, is planned to tour throughout the Americas.

From cytoplasm to environment: The inorganic ingredients for the origin of life

Early in its history, Earth's surface developed from an uninhabitable magma ocean to a place where life could emerge. The first organisms, lacking ion transporters, fixed the composition of their cradle environment in their intracellular fluid. Later, though life adapted and spread, it preserved some qualities of its initial environment within. Modern prokaryotes could thus provide insights into the conditions of early Earth and the requirements for the emergence of life. In this work, we constrain Earth's life-forming environment through detailed analysis of prokaryotic intracellular fluid. Rigorous assessment of the constraints placed on the early Earth environment by intracellular liquid will provide insight into the conditions of abiogenesis, with implications not only for our understanding of early Earth but also the formation of life elsewhere in the Universe.

Biochemical profile of the Pêga donkey (Equus asinus) breed: influence of age and sex

Inappropriate reference limits increase the risks of unnecessary investigations and diagnostic failures. Species, breed, environment, handling, and physiologic stage can influence serum biochemical variables. This study aimed to establish serum biochemical reference intervals of Pêga donkeys and the influence of age and sex on these variables. Samples were taken from 110 donkeys (79 females and 31 males; 8 under 1 year, 33 between 1 and 3 years, and 69 over 3 years old). There were no differences for creatine kinase (CK), albumin, urea, and magnesium among age groups. Animals under 1 year old had the lowest aspartate aminotransferase (AST), creatinine, triglycerides, total calcium, and chloride means; lower indirect bilirubin, gamma-glutamyl transferase (GGT), alanine aminotransferase (ALT), and sodium levels than over 3-year-old group and the highest phosphorus, glucose, cholesterol, ionized calcium, and alkaline phosphatase (AP) values. Total protein increased with age. The group from 1 to 3 years had higher potassium than up to 1-year-old group. Animals over 3 years old had the highest means of direct and total bilirubin. ALT, CK, GGT, direct and total bilirubin, urea, triglycerides, sodium, potassium, and chloride levels did not differ between genders. Females had higher AST, total protein, total calcium, and indirect bilirubin levels. Males showed greater AP, albumin, phosphorus, glucose, creatinine, cholesterol, magnesium, and ionized calcium values. Discrepancies among present results and previous studies show influencing factors on biochemical profile of donkeys and reinforce the importance of establishment of specific reference intervals. This study is useful in clinical routine and as basis to other scientific researches with Pêga donkeys. © 2013 Springer-Verlag London.

Serum activity of creatine kinase and aminotransferase aspartate enzymes of horses submitted to muscle biopsy and incremental jump test

The objective was to evaluate serum activity of the enzymes creatine kinase (CK) and aspartate aminotransferase (AST), which are leakage enzymes responsive to muscle injury, of athletic horses that underwent muscle biopsy and incremental jump test (IJT) involving incremental jumps. The animals were grouped as follows: the first group, horses with history of superior performance (SP); the second, with a history of inferior performance (IP); and lastly, a control group (CG). All groups underwent biopsy of the gluteus medius muscle, while groups SP and IP were also submitted to the incremental jump test (IJT) 24 hours after biopsy. The IJT consisted of three stages with 40 jumps each, where jump height increased progressively, from 40 to 60 and last, 80cm. Blood samples were drawn before biopsy, and 6 and 24 hours after the exercise as well. The levels of CK serum activity increased 6 hours after exercise and decreased 24 hours later in all groups, including CG. AST activity did not increase after biopsy and exercise. There was no increase of both enzyme activities that could be attributed to the exercise, possibly due to exercise short duration and/or low intensity. We conclude that the muscle biopsy was able to show that there was enough stimulus to cause CK enzyme leakage into the plasma, and consequent detection of increased serum activity, while the incremental jump test did not.
