Quick and easy method for determination of priority phenolic compounds in water and wastewater

open access: yesJournal of Xenobiotics, 2014
Phenols and phenolic compounds are ubiquitous contaminants in the environment. Due to toxic potential, some phenolic compounds mainly chlorophenols and nitrophenols have been classified as priority pollutants.

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

« Dave felt the future seething, the present boiling, the past churning. » Quelques cas de résurgence dans The Book of Dave : A Revelation of the Recent Past and the Distant Future, de Will Self

open access: yesÉtudes Britanniques Contemporaines, 2009
Resurgence is a term which implies that a stream courses beneath the surface before it issues from the ground. This concept seems to be linked to the notion of disappearance by a relation of temporal causality.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Application of a Novel, Mega-event Environmental Impact Assessment Critique Framework: The 34th America's Cup Races Case Study

open access: yesEdinburgh Student Journal of Science
Environmental impact assessments have a primary goal of balancing anthropogenic development with environmental protection. While critique methodologies for standard impact assessments are well-established, existing frameworks often fall short in ...

Determination of 16 Selected Trace Elements in Children Plasma from China Economical Developed Rural Areas Using High Resolution Magnetic Sector Inductively Coupled Mass Spectrometry

open access: yesJournal of Analytical Methods in Chemistry, 2014
A rapid, accurate, and high performance method of high resolution sector field inductively coupled plasma mass spectrometry (HR-ICP-MS) combined with a small-size sample (0.1 mL) preparation was established.

Traces of hypergraphs

open access: yesJournal of the London Mathematical Society, 2019
Let $\text{Tr}(n,m,k)$ denote the largest number of distinct projections onto $k$ coordinates guaranteed in any family of $m$ binary vectors of length $n$. The classical Sauer-Perles-Shelah Lemma implies that $\text{Tr}(n, n^r, k) = 2^k$ for $k \le r$. While determining $\text{Tr}(n,n^r,k)$ precisely for general $k$ seems hopeless even for constant $r$,

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

The Practical Value of Xpert MTB/RIF Ultra for Diagnosis of Pulmonary Tuberculosis in a High Tuberculosis Burden Setting: a Prospective Multicenter Diagnostic Accuracy Study

open access: yesMicrobiology Spectrum, 2022
Due to the probability of decreased specificity, the practical value of performing the Xpert MTB/RIF Ultra (Xpert Ultra) assay over the Xpert assay for diagnosing pulmonary tuberculosis (TB) and rifampicin (RIF) resistance in a high TB burden setting was

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
