Because animal studies are labor intensive, predictive equations are used extensively for calculating metabolizable energy (ME) concentrations of dog and cat pet foods. The objective of this retrospective review of digestibility studies, which were conducted over a 7-year period and based upon Association of American Feed Control Officials (AAFCO) feeding...
Pyrenophora tritici-repentis (Ptr) is the necrotrophic fungus responsible for tan spot of wheat (Triticum aestivum). Ptr causes disease on susceptible wheat cultivars through the production and secretion of host-selective toxins (HSTs). HSTs are compounds that are only known to be produced by fungi and considered to be primary determinants of...
Background:
Symmetric dimethylarginine (SDMA) is an accurate and precise biomarker for estimating glomerular filtration rate (GFR) in humans and cats. Serum creatinine (sCr) also correlates with GFR, but has limitations as a biomarker of renal function because nonrenal factors can influence its concentration.
Hypothesis:
Differences in lean body mass (LBM)...
The RV Ronald H. Brown traveled a section of tropical Atlantic waters northeast of Barbados during January-February 2020 in an international collaboration effort known as Elucidating the Role of Clouds Circulation Coupling in Climate Campaign (EUREC4A). ATOMIC (Atlantic Trade-wind Ocean–Atmosphere Mesoscale Interaction Campaign) was the US contribution to EUREC4A focused...
Pyrenophora tritici-repentis, causal agent of tan spot of wheat, produces multiple
host-selective toxins (HSTs), including Ptr ToxA, encoded for by ToxA, Ptr ToxB,
encoded for by ToxB, and Ptr ToxC. Variable distribution of these three HSTs among
different isolates of P. tritici-repentis, both singularly and in all possible combinations,
defines...
Graphium sp., a eukaryotic alkanotroph, is able to oxidize small-molecular weight gaseous n-alkanes, diethyl ether and the branched ether, methyl tert butyl ether
(MTBE). However, information regarding the biochemistry of fungal-mediated alkane and ether metabolism is limited, and questions regarding the identity of alkane oxidation catalysts and the genetic underpinnings...
Pyrenophora tritici-repentis (Ptr) is the causal agent of the disease tan spot of wheat,
which can be responsible for the destruction of up to 50% of a wheat crop harvest.
Tan spot disease results in chlorotic and/or necrotic lesions triggered by the
pathogen’s production of one or several host-selective toxins...

Pyrenophora tritici-repentis (Ptr) is the causal agent of the disease
Pyrenophora tritici-repentis (Ptr) is the fungal causal agent of the disease tan spot in wheat and causes necrosis and chlorosis in infected leaves. These symptoms are caused by host-selective toxins (HSTs), molecules that serve as the sole determinants of pathogenicity. Ptr has three known HSTs, the proteinaceous Ptr ToxA and...

Greenhouse gases effects are a leading contributor to climate change; reducing harmful effects of these gases is important for future generations. Worldwide, household consumption makes up seventy-two percent of greenhouse gas emissions, followed by government consumption at ten percent, and investments at eighteen percent (Hertwich, 2009). In order to understand...
