CONDUTIVIDADE HIDRÁULICA NO PROCESSO DE ELUIÇÃO EM UM SOLO BRUNO-NÃO-CÁLCICO

open access: yesScientia Agricola, 1996
Com o objetivo de avaliar o efeito da porcentagem de sódio trocável do solo e da concentração eletrolítica da água de percolação, sobre a condutividade hidráulica em um solo Bruno-Não-Cálcico da região do Rio Salitre-BA, o presente experimento foi ...

Highly multiplexed digital PCR assay for simultaneous quantification of variant allele frequencies and copy number alterations of KRAS and GNAS in pancreatic cancer precursors

open access: yesMolecular Oncology, EarlyView.
Combining melting curve analysis enhances the multiplexing capability of digital PCR. Here, we developed a 14‐plex assay to simultaneously measure single nucleotide mutations and amplifications of KRAS and GNAS, which are common driver genes in pancreatic cancer precursors. This assay accurately quantified variant allele frequencies in clinical samples

The best practice for preparation of samples from FTA®cards for diagnosis of blood borne infections using African trypanosomes as a model system [PDF]

open access: yes, 2011
Background: Diagnosis of blood borne infectious diseases relies primarily on the detection of the causative agent in the blood sample. Molecular techniques offer sensitive and specific tools for this although considerable difficulties exist when using ...

A large‐scale retrospective study in metastatic breast cancer patients using circulating tumour DNA and machine learning to predict treatment outcome and progression‐free survival

open access: yesMolecular Oncology, EarlyView.
There is an unmet need in metastatic breast cancer patients to monitor therapy response in real time. In this study, we show how a noninvasive and affordable strategy based on sequencing of plasma samples with longitudinal tracking of tumour fraction paired with a statistical model provides valuable information on treatment response in advance of the ...

Dynamic delta method for trace gas analysis [PDF]

open access: yes, 1975
Method has been developed in which measurements are made only over viscous flow range, eliminating fractionation before the molecular leak and problems due to surface ...

Synthesis and application of hypercrosslinked polymers with weak cation-exchange character for the selective extraction of basic pharmaceuticals from complex environmental water samples [PDF]

open access: yes, 2010
The synthesis of high specific surface area sorbents (HXLPP-WCX) in the form of hypercrosslinked polymer microspheres with narrow particle size distributions, average particle diameters around 6 µm, and weak cation exchange (WCX) character, is described.

Microscale Rearrangement of Ammonium Induced by Snow Metamorphism

open access: yesFrontiers in Earth Science, 2019
Earth’s snowpack hosts chemical impurities that exchange with the overlying air, strongly impacting atmospheric chemistry. Being embedded in firn and glacier ice formed from surface snow, impurities provide the basis for reconstructing past atmospheric ...

Multidimensional OMICs reveal ARID1A orchestrated control of DNA damage, splicing, and cell cycle in normal‐like and malignant urothelial cells

open access: yesMolecular Oncology, EarlyView.
Loss of the frequently mutated chromatin remodeler ARID1A, a subunit of the SWI/SNF cBAF complex, results in less open chromatin, alternative splicing, and the failure to stop cells from progressing through the cell cycle after DNA damage in bladder (cancer) cells. Created in BioRender. Epigenetic regulators, such as the SWI/SNF complex, with important

amsrpm: Robust Point Matching for Retention Time Aligment of LC/MS Data with R

open access: yesJournal of Statistical Software, 2007
Proteomics is the study of the abundance, function and dynamics of all proteins present in a living organism, and mass spectrometry (MS) has become its most important tool due to its unmatched sensitivity, resolution and potential for high-throughput ...

Impact of Manual Addition of Vancomycin to Polymethylmethacrylate (PMMA) Cements

open access: yesAntibiotics
(1) Background: The addition of antibiotics to bone cements is a common practice in the treatment of periprosthetic joint infections. In revision cases, the amount and type of antibiotic is often insufficient and additional antibiotics must be added. The
