Juvenile hormone pathway in honey bee larvae: A source of possible signal molecules for the reproductive behavior of Varroa destructor

Ecology and Evolution, Volume 11, Issue 2, Page 1057-1068, January 2021., 2021
In an effort to answer a long‐standing question on how hormonal interactions in the honey bee larvae can sustain the parasite Varroa destructor reproduction, the current study focused on differential expression analysis of the genes involved in the Juvenile hormone (JH) and ecdysteroid associated pathways. All the results were discussed considering the

Rates of Spontaneous Cleavage of Glucose, Fructose, Sucrose, and Trehalose in Water, and the Catalytic Proficiencies of Invertase and Trehalas [PDF]

, 2008
Most of the early experimental work on enzyme kinetics was based on the properties of yeast invertase (-fructo-furanosidase, EC 3.2.1.26), whose robust activity1 (together with the availability of a continuous polarimetric assay) enabled Michaelis and ...

Phosphatases in the soil environment [PDF]

, 1980
Enzymes play a key role in nutrient cycling in the soil environment. In this work, four phosphatases of the soil environment were investigated. A study of the effect of metal ions and metal ion concentrations on inorganic pyrophosphatase activity in ...

Community proteogenomics reveals the systemic impact of phosphorus availability on microbial functions in tropical soil. [PDF]

, 2018
Phosphorus is a scarce nutrient in many tropical ecosystems, yet how soil microbial communities cope with growth-limiting phosphorus deficiency at the gene and protein levels remains unknown.

Discovering structural motifs using a structural alphabet: Application to magnesium-binding sites [PDF]

, 2007
BACKGROUND: For many metalloproteins, sequence motifs characteristic of metal-binding sites have not been found or are so short that they would not be expected to be metal-specific.

Micellar electrokinetic chromatography after precapillary enzyme assay for the determination of phosphatase activity in semiarid soil [PDF]

, 2009
Inorganic phosphorous (P) is an essential plant nutrient that must be added to most soils to maintain plant growth and sustain crop yields. Phosphatase enzymes play a major role in the processes of mineralization of organic P substrates.

Risk to human health related to the presence of perfluoroalkyl substances in food

EFSA Journal, Volume 18, Issue 9, September 2020., 2020
Abstract The European Commission asked EFSA for a scientific evaluation on the risks to human health related to the presence of perfluoroalkyl substances (PFASs) in food. Based on several similar effects in animals, toxicokinetics and observed concentrations in human blood, the CONTAM Panel decided to perform the assessment for the sum of four PFASs ...

The Impact of Modern Therapeutic Methods on the Oxidant‐Antioxidant Equilibrium and Activities of Selected Lysosomal Enzymes and Serine Protease Inhibitor in Amateur Athletes

Oxidative Medicine and Cellular Longevity, Volume 2020, Issue 1, 2020., 2020
Deep electromagnetic stimulation (DEMS) and low‐frequency ultrasound (US) are new physical therapy methods used in the rehabilitation of the musculoskeletal system and wound healing. They are applied locally to treat the injured tissues. The beneficial effects of these methods in supportive care have been documented, but accurate biochemical effects ...
