Producción de sulfato de cobre pentahidratado a partir de cemento de cobre

Revista del Instituto de Investigación de la Facultad de Ingeniería Geológica, Minera, Metalúrgica y Geográfica, 2005
In the south part of the country there oxidated copper minerals hard to leach and when you do it you get extracts are rich in copper but also contain polliting agents, that produces copper sulfate that does not match with the technical characteristics requiered for its industry use.

Oral Microbiome Resilience During SARS‐CoV‐2 Infection and Diversity Shifts After COVID‐19 Vaccination in a Hispanic Population

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
The oral microbiome in Hispanics remains largely resilient during mild SARS‐CoV‐2 infection, showing minimal diversity changes, while COVID‐19 vaccination induces increased microbial evenness and compositional shifts. These findings highlight limited infection impact but suggest vaccination transiently reshapes oral microbial ecology.

Use of tandem‐affinity chromatography to incorporate nucleotide loading of small GTPases during their purification

Protein Science, Volume 35, Issue 6, June 2026.
Abstract A bottleneck for structure–function studies of closely related proteins is purification. Here, we built upon new affinity protein purification technology to develop a uniform and rapid tandem‐affinity purification protocol to generate significant quantities of pure GTPase proteins for use in structure–function studies. Our method relies on new

An unsupervised machine learning approach to iron meteorite classification

Meteoritics &Planetary Science, Volume 61, Issue 6, Page 997-1011, June 2026.
Abstract Iron meteorites are usually classified manually using bivariate elemental plots. This study extends iron meteorite classification into multi‐element space. We present a computational method for the classification of iron meteorites by applying unsupervised machine learning using density‐based cluster analysis.

The Age‐Dependent Resident Myonuclear Multi‐Omic Response to an Acute Skeletal Muscle Hypertrophic Stimulus in Mice

Advanced Science, Volume 13, Issue 25, 4 May 2026.
Resident myonuclei are the molecular “control centers” for large multinuclear muscle fibers. It is presumed that, with aging, these control centers become compromised and contribute to delayed or blunted muscle adaptive potential. This study is a detailed roadmap that exposes how young versus aged myonuclei respond to a hypertrophic loading stimulus ...

Changes in arterial stiffness under blood pressure control are independently associated with cognitive impairment: The Systolic Blood Pressure Intervention Trial (SPRINT)

Alzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Blood pressure treatment‐related changes in arterial stiffness measures over 3 years and their longitudinal relationships with time to incident cognitive impairment over 10 years in the Systolic Blood Pressure Intervention Trial. Longitudinal progression of systolic blood pressure and pulse wave velocity (PWV) components under intensive versus standard

Plant growth-promoting bacteria in sorghum development in coppercontaminated soil

Revista Brasileira de Ciências Ambientais
O cobre é um metal que pode se tornar tóxico para o sorgo quando presente em altas concentrações no solo. A utilização de rizobactérias promotoras do crescimento de planta pode ser uma alternativa para o desenvolvimento do sorgo [Sorghum bicolor (L ...

APOE4 Drives Sex‐ and Diet‐Dependent Effects on AD‐Like Pathology, Cognition, and Mitochondrial Function

FASEB BioAdvances, Volume 8, Issue 5, May 2026.
APOE4 interacts with sex and diet to influence brain mitochondrial function. ABSTRACT Apolipoprotein E4 (APOE4) is the strongest genetic risk factor for Alzheimer's disease (AD), yet it's unclear how this allele promotes disease. While factors like diet and sex may modify AD susceptibility in APOE4 carriers, the interaction between these factors is ...
