Altitudinal gradients in Magellanic sub-Antarctic lagoons: the effect of elevation on freshwater macroinvertebrate diversity and distribution
In this article, freshwater macroinvertebrate diversity associated with lakes and ponds along the altitudinal gradient of a Magellanic sub-Antarctic watershed are assessed. A monotonic decline in species richness was observed with increasing elevation, with simpler and more even community composition at higher altitude. This pattern differs from the mid-peak trend found in streams of the same watershed. Functional feeding group structure also diminished with increasing elevation.

Cardiac and metabolic physiology of early larval zebrafish (Danio rerio) reflects parental swimming stamina
Article describes experiment in which mature adult zebrafish (Danio rerio) were subjected to a swimming performance test that allowed separation into low swimming stamina or high swimming stamina groups in order to determine if inherited traits that support enhanced swimming stamina in offspring appear only in juveniles and/or adults, or if these traits actually appear earlier in the morphologically quite different larvae.

Hypoxic level and duration differentially affect embryonic organ system development of the chicken (Gallus gallus)
This article investigates how key organ systems are affected by hypoxia. The results indicated that either modest hypoxia (15% O2) throughout development, or hypoxia at any level during the late stages (d 11 to 18), increased the heart and chorioallantoic membrane weight, which partly compensated for the detrimental effects of hypoxia on embryonic development.

Effect of selection for commercially productive traits on the plasticity of cardiovascular regulation in chicken breeds during embryonic development
Article investigates basic cardiovascular physiology in the Red Junglefowl, the broiler, and the White Leghorn breeds at 90% of incubation. The authors aimed to identify breed-specific features of arterial blood pressure and heart rate as well as the physiological mechanisms regulating them. They concluded that selection for rapid growth shifts cardiovascular regulatory plasticity to emphasize mechanisms that modulate pressure, and that selection for egg-laying capacity emphasizes mechanisms that modulate heart rate.

Thymoquinone overcomes chemoresistance and enhances the anticancer effects of bortezomib through abrogation of NF-κB regulated gene products in multiple myeloma xenograft mouse model
Article investigates whether thymoquinone (TQ), a bioactive constituent of black seed oil, could suppress the proliferation and induce chemosensitization in human myeloma cells and xenograft mouse model. Overall, the results demonstrate that TQ can enhance the anticancer activity of bortezomib in vitro and in vivo and may have a substantial potential in the treatment of MM.

Development and use of a switchgrass (Panicum virgatum L.) transformation pipeline by the BioEnergy Science Center to evaluate plants for reduced cell wall recalcitrance
Article examines the creation of a transformation pipeline (TP) to produce plants with decreased recalcitrance and a laboratory information management system (LIMS) for data compilation from these plants. While many genes accepted into the TP resulted in transgenic switchgrass without modified lignin or biomass content, a group of genes with potential to improve lignocellulosic biofuel yields was identified. Results from transgenic lines targeting xyloglucan and lignin structure provide examples of the types of information available on switchgrass lines produced within BioEnergy Science Center (BESC).
