[1] Boreal wetland carbon cycling is vulnerable to climate change in part because hydrology and the extent of frozen ground have strong influences on plant and microbial functions. We examined the response of dissolved organic carbon (DOC) and total dissolved nitrogen (TDN) across an experimental manipulation of water table position (both raised and lowered water table treatments) in a boreal‐r...

Loss of functional p53 paradoxically results in either increased or decreased resistance to chemotherapeutic drugs. The inconsistent relationship between p53 status and drug sensitivity may reflect p53's selective regulation of genes important to cytotoxic response of chemotherapeutic agents. We reasoned that the discrepant effects of p53 on chemotherapeutic cytotoxicity is due to p53-dependent...

In livestock nutrition, summative models (SM) are displacing empirical models as a preferred method to predict energy content of forages. The objective of this study was to determine the effect of using near infrared reflectance spectroscopy (NIRS) to determine nutrient subcomponents required of SM on overall ability to predict energy content of corn and legume-grass silages. Corn (n = 90) and ...

We describe the clinical outcome of a novel nerve transfer to restore active shoulder motion in upper brachial plexus injury. The thoracodorsal nerve (TDN) was successfully used as a vascularized donor nerve to neurotize to the suprascapular nerve (SSN) in a patient with limited donor nerve availability. At 4 years follow-up, he had regained useful external rotation of the injured limb, with no...

Relatively high deposition of nitrogen (N) in the northeastern United States has caused concern because sites could become N saturated. In the past, mass-balance studies have been used to monitor the N status of sites and to investigate the impact of increased N deposition. Typically, these efforts have focused on dissolved inorganic forms of N (DIN = NH4-N + NO3-N) and have largely ignored dis...

In the past decade a series of studies have shown that the active transport of inorganic carbon and nutrients by diel vertical migration of zooplankton is an important component of the biological pump. Less well known is how excretion of dissolved organic material (DOM) by migrating zooplankton enhances this export by creating a migratory DOM pump. We measured ammonia (NH4 ) and dissolved organ...

• Norisoprenoids are important compounds that contribute to the aroma of wines. Examples of norisoprenoids are ß-ionone and ß-damascenone , which contribute intense fruity aromas; TDN (trimethyldihydro-naphtalene), which contributes the typical kerosene, or petrol, note in wines (in high concentrations, TDN may be considered a defect); and actinidol and vitispirane , which contribute other comp...

Recently, international human rights leaders have renewed the call for advocacy on economic, social, and cultural rights and suggested partnerships with local organizations. The Thai Drug Users' Network (TDN) promotes the human rights of a marginalized and medically underserved population within Thailand. It also works internationally to reduce drugrelated harms. Thus, TDN transcends a strict l...

Cystic fibrosis (CF), the most common life-shortening genetic disorder in Caucasians, affects approximately 70 000 individuals worldwide. In 1998, the Cystic Fibrosis Foundation (CFF) launched the CF Therapeutics Development Network (CF-TDN) as a central element of its Therapeutics Development Programme. Designed to accelerate the clinical evaluation of new therapies needed to fulfil the CFF mi...

We introduce moduli spaces of quasi-admissible hyperelliptic covers with at worst A and D singularities. Stability conditions for these moduli problems depend on two parameters describing allowable singularities. At the extreme values of the parameters, we obtain the stacks TAn and TDn of stable limits of An and Dn singularities, as well as the quotients of the miniversal deformation spaces of ...
