A PROPOSAL OF PROCESS VALIDATION IN THE IMPLEMENTATION OF GOOD MANUFACTURING PRACTICES IN BRACHYTHERAPY SOURCES PRODUCTION

Brazilian Journal of Radiation Sciences, 2021
New laboratories for brachytherapy sources production are being implemented in our facility at IPEN, in São Paulo. A great challenge implementing a production laboratory is to comply with the Good Manufacturing Practices (GMPs), which involves process ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Byproduct-based zeolite type A as absorbent material for decontamination of simulated radioactive wastewater

Brazilian Journal of Radiation Sciences
The secure disposal of radioactive wastewater, a waste from nuclear operations, presents a significant challenge due to the presence of hazardous radionuclides like cesium.

Determination of α+nucleus optical potential relevant for p-process study from the natIn(α, α) elastic scattering [PDF]

EPJ Web of Conferences
The knowledge of alpha optical potential is important for determining the nuclear reaction rates. natIn(α, α)natIn elastic scttering cross-sections have been measured at energies Elab = 26 and 29 MeV above the coulomb barrier.

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Calibration coefficients of epitaxial diodes used in diagnostic radiology and computed tomography beams

Brazilian Journal of Radiation Sciences
The assessment of the calibration coefficients of an epitaxial diode, previously characterized for diagnostic radiology (RQR qualities) and computed tomography (RQT qualities) dosimetry, is reported in this work. The diode, with an n-type epitaxial layer

Radiation hazard indices in the application of phosphogypsum mixtures as a building material: proposal for a Brazilian regulation

Brazilian Journal of Radiation Sciences, 2019
Phosphogypsum (PG), a by-product from the phosphoric acid industry, is being worldwide stockpiled, posing environmental problems. Viability of the PG safe re-use in civil construction has been studied, as PG can contain natural radionuclides in ...

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

FEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...
