Towards Detecting The 2175-{\AA} Dust Feature Associated With Strong High Redshift Mg {\ss}II Absorption Lines

open access: yes, 2011
We report detections of 39 2175-{\AA} dust extinction bump candidates associated with strong Mg II absorption lines at z$\sim$ 1--1.8 on quasar spectra in Sloan Digital Sky Survey (SDSS) DR3.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Crystal growth and structural analysis of perovskite chalcogenide BaZrS$_3$ and Ruddlesden-Popper phase Ba$_3$Zr$_2$S$_7$

open access: yes, 2019
Perovskite chalcogenides are gaining substantial interest as an emerging class of semiconductors for optoelectronic applications. High quality samples are of vital importance to examine their inherent physical properties. We report the successful crystal

AAA+ protein unfoldases—the Moirai of the proteome

open access: yesFEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Tratamiento del derrame pleural neoplásico con talco iodado

open access: yesCirugía del Uruguay, 1982
Se analizan 23 pacientes que presentaban un derrame pleural neoplásico, a 22 se les efectuó tratamiento de su derrame con espolvoreo de talco iodado. En uno, sólo se utilizó talco dado que era alérgico al iodo. Trece de ellos tuvieron tratamiento previo

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

open access: yesMolecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

Ampliación de la resección en la vía canalicular

open access: yesCirugía del Uruguay, 1982
En la cirugía por cáncer de pulmón la resección ampliada a la vía canalicular se plantea en dos situaciones: lobectomía ensanchada a bronquio fuente y neumonectomía ensanchada a carina.
