Effective atomic number of some rare earth compounds determined by the study of external bremsstrahlung

Journal of Radiation Research and Applied Sciences, 2015
In this paper we report the effective atomic number (Zeff) of some rare earth compounds determined from the measured external bremsstrahlung (EB) intensity due to the incident beta particles emitted by the 90Sr-90Y source. For this purpose the two sample

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Impact of high BaO content on tuning the structural, optical and radiation shielding properties of multicomponent borate glasses

Journal of Science: Advanced Materials and Devices
The impact of increasing BaO concentration on the B2O3-CaO-ZnO-BaO-Er2O3 glass samples' properties has been examined. The increase in density and molar volume is observed. FTIR analysis reveals the disruption of borate units and the creation of NBOs with

Pb-free Radiation Shielding Glass Using Coal Fly Ash

Journal of Mathematical and Fundamental Sciences, 2015
In this work, Pb-free shielding glass samples were prepared by the melt quenching technique using subbituminous fly ash (SFA) composed of xBi2O3 : (60-x)B2O3 : 10Na2O : 30SFA (where x = 10, 15, 20, 25, 30 and 35 by wt%). The samples were investigated for

Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Comprehensive study of photon and proton interactions to interpret the radiation parameters of boron derivative drugs for chemoradiotherapy

Journal of Nigerian Society of Physical Sciences
 For chemoradiotherapy applications, this work investigated the photon and proton interaction parameters in five boron-based medications: sodium borocaptate, bortezomib, delanzomib, boronophenylalanine, and boric acid. Photon interaction parameters such

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
