Breast cancer supplemental screening: Women’s knowledge and utilization in the era of dense breast legislation

open access: yesCancer Medicine, 2020
Background Given the growth in dense breast notification (DBN) legislation in the United States, we examined the association between different types of DBN laws and supplemental screening behaviors among women.

An approach for coherent periodogram averaging of tilt‐series data for improved contrast transfer function estimation

open access: yesFEBS Open Bio, EarlyView.
The contrast transfer function (CTF) is an imaging aberration that is a major resolution‐limiting factor in cryo‐electron microscopy (cryo‐EM). Precise CTF estimation is key to overcoming this limitation, but is particularly challenging in cryo‐electron tomography (cryo‐ET) data. Here, we present an approach for using geometric information to assist in

Copper metallothioneins [PDF]

open access: yesIUBMB Life, 2017
AbstractMetallothioneins (MTs) are a class of low molecular weight and cysteine‐rich metal binding proteins present in all the branches of the tree of life. MTs efficiently bind with high affinity several essential and toxic divalent and monovalent transition metals by forming characteristic polynuclear metal‐thiolate clusters within their structure ...

Earthing effects on mitochondrial function: ATP production and ROS generation

open access: yesFEBS Open Bio, EarlyView.
In contrast to sham and naive controls, grounded mitochondria not only exhibit significantly enhanced energy production but also demonstrate a remarkable reduction in membrane potential and oxidative stress. This suggests a profound improvement in mitochondrial health, presenting a promising avenue for therapeutic interventions.

The Effect of Copper Mineral, Copper Sulfate and Copper Nanoparticles on Fish

open access: yes, 2023
Copper is a mineral element that is widely found in nature and is very important for humans and aquatic animals as an essential element for the growth and development of fish and also in the activity of biochemical enzymes and in processes such as blood production, immune system, The production of energy molecules and salt water balance plays an ...

Interaction of class III cellobiose dehydrogenase with lytic polysaccharide monooxygenase

open access: yesFEBS Open Bio, EarlyView.
The activity of lytic polysaccharide monooxygenase (LPMO) is supported by its auxiliary enzyme cellobiose dehydrogenase (CDH). The catalytic activity of both enzymes is coupled by electron transfer and a cyclic cascade generating substrates for both enzymes – hydrogen peroxide for LPMO and oxidized and non‐oxidized cellobiose and cello‐oligosaccharide ...

Structure of the catalytically active copper–ceria interfacial perimeter

open access: yesNature Catalysis, 2019
Cu/CeO2 catalysts are highly active for the low-temperature water–gas shift—a core reaction in syngas chemistry for tuning the H2/CO/CO2 proportions in feed streams—but the direct identification and quantitative description of the active sites remain ...

A Copper 7 IUCD with no copper. [PDF]

open access: yesBMJ, 1979
Whether the loss of copper from interuterine devices is from defects in copper winding or from the copper dissolving in the uterus is uncertain. The gravigard a small plastic device has 32 cm of copper wire making it 7-10 times as effective as similar devices without copper.

Liver‐specific lncRNAs associated with liver cancers

open access: yesFEBS Open Bio, EarlyView.
Long non‐coding RNAs (lncRNAs) are regulatory molecules with various functions. They are more tissue‐specific than proteins and can be used as potential biomarkers, particularly in cancer diagnostics and prognosis. In this review, we have systematically compiled all lncRNAs with exclusive expression in the human liver, verified their liver specificity ...
