Analysis and Conservation of Native Forests at Kessler Mountain Fayetteville, Arkansas [PDF]

open access: yes, 2019
Kessler Mountain in Fayetteville Arkansas has long been recognized for its beauty and natural resources. Parts of Kessler Mountain have been homesteaded and developed in the past, but most of the mountain has remained relatively undisturbed.

Reduction of Ribonucleotide Reductase Subunit RRM2 Potentially Impairs Gut Function of Woody Breast Broilers

open access: yesAnimal Research and One Health, EarlyView.
Woody breast compromises meat quality leading to reduced consumer appeal. Although its causes are unclear, improvements observed with certain dietary supplements suggest that gut health may influence woody breast development. Ribonucleotide reductase subunit RRM2 is vital for mitochondrial function and gastrointestinal integrity, and alteration in its ...

Litter dynamics and phenology of Melaleuca quinquenervia in south Florida [PDF]

open access: yes, 2002
We monitored litterfall biomass at six different sites of melaleuca (Melaleuca quinquenervia (Cav.) S.T. Blake) forested wetlands in South Florida from July 1997 to June 1999.

Increasing the succinate yield in Actinobacillus succinogenes by fumigation of H2 in a bioreactor

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The microbial conversion of CO2 into value‐added chemicals offers a promising and scalable route for sustainable bioproduction, particularly under mild reaction conditions and with technically straightforward reactor configurations. Actinobacillus succinogenes, a natural succinate producer, can fix CO2 through anaplerotic carboxylation but its

How tightly linked are Pericopsis elata (Fabaceae) patches to anthropogenic disturbances in Southeastern Cameroon? [PDF]

open access: yes, 2015
While most past studies have emphasized the relationships between specific forest stands and edaphic factors, recent observations in Central African moist forests suggested that an increase of slash-and-burn agriculture since 3000–2000 BP (Before Present)

Volumetric mass transfer and dilution rate as key parameters for sustainable industrial syngas fermentation to isopropyl alcohol: modeling and parametric assessment

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Synthesis gas fermentation is a promising route for the valorization of steel mill off‐gas and for replacing conventional fossil‐based isopropyl alcohol (IPA) production. A recent 120 L pilot‐scale study reported 85% gas conversion at 90% product selectivity and claimed a negative global warming potential (GWP) without detailed process design.

Effect of Genotype, Gender, and Feed Restriction on Slaughter Results and Meat Quality of Broiler Chickens [PDF]

open access: yes, 2017
Slaughter results and meat quality were evaluated in 768 broilers according to genotype (standard breast yield vs. high breast yield), gender, and feeding systems (ad libitum vs. feed restriction from 13 to 21 d of age).

Pharmacogenetic CYP2B6 variants affect steroid hormone metabolism in human breast cancer cells

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Common genetic CYP2B6 variants correlate with adverse breast cancer outcome. The oestrogen metabolites estriol and 16‐epiestriol, which are formed downstream of CYP2B6‐catalysed 16α/β‐hydroxytestosterone, may be linked to elevated breast cancer risk and might increase due to the demonstrated CYP2B6 variants‐related metabolic shifts.

Dynamic Immune Cell Composition, Phenotypes, and Signaling in an Engineered Metastatic Niche

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT In breast cancer patients, metastasis is the stage of disease where prognosis significantly worsens. However, the timing at which metastasis initiates and the location of metastatic lesions in an organ are stochastic, limiting the timely identification of disease and the administration of treatments.
