The effects of silicon (Si) amendment have been studied in several plant/pathogen interactions; however, studies in horticultural tree crops are limited. Effects of amendment with soluble potassium silicate (AgSil(®)32, approximately 30% available Si), or milled cement building board by-products (Mineral Mulch (MM) or Mineral Dust (MD), containing 5% available Si) were investigated in field and greenhouse trials with avocado. Orchard soil drench applications with potassium silicate improved yield and quality of fruit, but visual health of trees declining from Phytophthora root rot (PRR) was not affected...

Saccharomyces species, which are mostly used in the food and beverage industries, are known to differ in their fermentation efficiency and tolerance of adverse fermentation conditions. However, the basis of their difference has not been fully elucidated, although their genomes have been sequenced and analyzed. Five strains of four Saccharomyces species (S. cerevisiae, S. kudriavzevii, S. bayanus, and S. paradoxus), when grown in parallel in laboratory conditions, exhibit very similar basic physiological parameters such as membrane potential, intracellular pH, and the degree to which they are able to quickly activate their Pma1 H(+)-ATPase upon glucose addition...

The perturbation of thyroid iodide uptake is a well-documented side effect of the utilization of iodinated contrast media (ICM) administrated intravenously. This side effect is thought to be mediated by free iodide in ICM formulations but this hypothesis has never been formally demonstrated. The aim of the present paper is to assess the validity of this hypothesis. Methods: We used mass spectrometry analysis to quantify free-iodide contamination in ICM. Established cell lines expressing the Na/I symporter (NIS) were used to quantify the effect of ICM on iodide uptake...

Dysregulated potassium (K(+)) channels have previously been shown to promote the development and progression of many types of cancers. Meanwhile, K(+) channels are particularly important in regulating the endocrine and exocrine functions of pancreas. However, the expression pattern and prognostic significance of K(+) channels in pancreatic ductal adenocarcinoma (PDAC) remain unknown. In this study, by screening a GEO dataset containing 36 microdissected PDAC and matching normal pancreatic tissue samples, four differentially expressed K(+) channels (KCNJ5, KCNJ16, KCNN4 and KCNK1) were identified in PDAC...

The fertilizing capacity of pure, fresh avian semen may disappear in just half an hour, hindering its successful use in artificial insemination (AI) projects. Longer storage requires the use of infra-physiological temperatures and of semen diluents that help preserve the spermatozoa but that do not interfere with their fertilizing capacity. This study examines the effect on sperm quality of storing red-legged partridge sperm for 3 h at 5°C with 2 different semen extenders: 1) a medium referred to as L&R-84, composed of sodium glutamate, glucose, magnesium acetate, potassium acetate, and polyvinylpyrrolidone, and 2) Lake 7...

Thyroid carcinoma (TC) is the most common endocrine neoplasm. The risk of TC as a second primary malignancy (SPM) of breast cancer is significantly increased. Bisphenol A (BPA) is a widely contacted xenoestrogen and increases susceptibility to breast cancer through binding to estrogen receptor alpha (ERα). However, the effect of BPA on thyroid carcinogenesis has not been fully demonstrated. This present study aimed to characterize the effects of BPA on the development of TC using a Fischer 344 (F344) rat model...

Opioids represent an efficacious therapeutic modality for some, but not all pain states. Singular reliance on opioid therapy for pain management has limitations, and abuse potential has deleterious consequences for patient and society. Our understanding of pain biology has yielded insights and opportunities for alternatives to conventional opioid agonists. The aim is to have efficacious therapies, with acceptable side effect profiles and minimal abuse potential, which is to say an absence of reinforcing activity in the absence of a pain state...
