CIPK-B is essential for salt stress signalling in Marchantia polymorpha.

Calcium signalling is central to many plant processes, with families of calcium decoder proteins having expanded across the green lineage and redundancy existing between decoders. The liverwort Marchantia polymorpha has fast become a new model plant, but the calcium decoders that exist in this species remain unclear. We performed phylogenetic analyses to identify the calcineurin B-like (CBL) and CBL-interacting protein kinase (CIPK) network of M.

ALK ligand ALKAL2 potentiates MYCN-driven neuroblastoma in the absence of ALK mutation.

High-risk neuroblastoma (NB) is responsible for a disproportionate number of childhood deaths due to cancer. One indicator of high-risk NB is amplification of the neural MYC (MYCN) oncogene, which is currently therapeutically intractable. Identification of anaplastic lymphoma kinase (ALK) as an NB oncogene raised the possibility of using ALK tyrosine kinase inhibitors (TKIs) in treatment of patients with activating ALK mutations.

Activity of Lysosomal Enzymes During Protein Malnutrition and Progesterone Supplementation in the Mouse.

This study investigated the effects of protein malnutrition and progesterone supplementation on the activities of a spectrum of lysosomal enzymes in tissue fragments of mouse liver and kidney. The working hypothesis was that the known anti-stress action of progesterone could have to do with the inhibition of lysosomes which are engaged in apoptotic and oxidative stress-induced responses. The study investigated the effects of exogenous progesterone in chronically (3 weeks) protein-malnourished (10% protein) mice on the activities of lysosomal hydrolases in liver and kidney tissues.

Epidemiological Aspects of Low Back Pain.

Low back pain (LBP) is a major health problem, particularly in the contemporary societies of highly developed countries. This study seeks to define the influence of basic demographic and social factors, such as gender, body mass, physical activity, and the type of work, on the occurrence of lumbosacral spine pain in the early and middle-late adulthood. The study was based on a self-reported survey, using the revised Oswestry Low Back Pain Disability Questionnaire to evaluate pain symptoms, and managing everyday tasks.

The impact of organic vs. inorganic selenium on dairy goat productivity and expression of selected genes in milk somatic cells.

The aim of this study was to determine the effect of diet supplemented with selenized yeast (Se-yeast) on milk yield and milk composition of goats and expression of casein and mammary-gland-immune system genes in milk somatic cells (MSC). Twenty-four dairy goats in their second to fourth lactations were divided into control and experimental groups, balanced according to lactation number and breed (Polish White or Fawn Improved). Morning milk and blood samples were collected four times during lactation (on the 21st, 70th, 120th, 180th day after kidding).
