Renal control of calcium, phosphate, and magnesium homeostasis.
American Society of Nephrology. Clinical Journal, 2015 Calcium, phosphate, and magnesium are multivalent cations that are important for many biologic and cellular functions. The kidneys play a central role in the homeostasis of these ions. Gastrointestinal absorption is balanced by renal excretion. When body

FEBS Letters, EarlyView.This work presents the characterization of MvoDUF2193, a Methanococcus voltae (Mvo) protein from the domain of unknown function (DUF) 2193 family. We demonstrate that MvoDUF2193 binds a single [4Fe–4S] cluster per subunit and that cluster occupancy regulates the transition from an apo tetramer to a [4Fe–4S] monomeric form. This structural transition is

Ca2+ Microdomains in T-Lymphocytes
Frontiers in Oncology, 2017 Early Ca2+ signaling is characterized by occurrence of Ca2+ microdomains formed by opening of single or clusters of Ca2+ channels, thereby initiating first signaling and subsequently activating global Ca2+ signaling mechanisms. However, only few data are

Efimov Physics around the neutron rich Calcium-60 isotope [PDF]
, 2013 We calculate the neutron-Calcium-60 S-wave scattering phase shifts using state of the art coupled-cluster theory combined with modern ab initio interactions derived from chiral effective theory.

ERBIN limits epithelial cell plasticity via suppression of TGF‐β signaling
FEBS Letters, EarlyView.In breast and lung cancer patients, low ERBIN expression correlates with poor clinical outcomes. Here, we show that ERBIN inhibits TGF‐β‐induced epithelial‐to‐mesenchymal transition in NMuMG breast and A549 lung adenocarcinoma cell lines. ERBIN suppresses TGF‐β/SMAD signaling and reduces TGF‐β‐induced ERK phosphorylation.

Dry Submicron Classification by a Small Blow Down Cyclone [Translated]†
KONA Powder and Particle Journal, 2014 At present, dry powders are classified using mainly a vortex centrifuge or sieving equipment, in which the lowest 50% cut size is still greater than one micrometer.

Calcium Bioavailability and Kinetics of Calcium Ascorbate and Calcium Acetate in Rats
Experimental Biology and Medicine, 2004 The objective was to investigate the bioavailability and mechanism of calcium absorption of calcium ascorbate (ASC) and calcium acetate (AC). A series of studies was performed in adult Sprague-Dawley male rats. In the first study, each group of rats (n = 10/group) was assigned to one of the five test meals labeled with 45Ca: (i) 25 mg calcium as ...

Calcium Homeostasis in Escherichia coli: Characterization of Mutants and Genome Expression of MG1655 [PDF]
, 2014 While the role of calcium ions as secondary messengers has been well described in eukaryotic cells, little is known about calcium homeostasis in bacteria at the physiological and molecular levels.
