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

FEBS 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

COVID-19 booster vaccine acceptance in North Central Nigeria: An application of the Integrated Behavioural Model

Journal of Interventional Epidemiology and Public Health
Introduction: The limited protection durability of the primary COVID-19 vaccines and the existential threats of variants with evasive mechanisms have necessitated the need to roll out booster vaccines in many countries.

Topological gravity in genus $2$ with two primary fields [PDF]

Advances in Theoretical and Mathematical Physics, 2000
We calculate the genus 2 correlation functions of two-dimensional topological gravity, in a background with two primary fields, using the genus 2 topological recursion relations.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Neural Field Model of Receptive Field Restructuring in Primary Visual Cortex

Neural Computation, 2001
Receptive fields (RF) in the visual cortex can change their size depending on the state of the individual. This reflects a changing visual resolution according to different demands on information processing during drowsiness. So far, however, the possible mechanisms that underlie these size changes have not been tested rigorously.

Primary singularities of vector fields on surfaces [PDF]

Geometriae Dedicata, 2019
Unless another thing is stated one works in the $C^\infty$ category and manifolds have empty boundary. Let $X$ and $Y$ be vector fields on a manifold $M$. We say that $Y$ tracks $X$ if $[Y,X]=fX$ for some continuous function $f\colon M\rightarrow\mathbb R$.

A cohort study of duplex Doppler examinations of the carotid artery in primary open angle glaucoma

, 2014
Objectives To explore the possibility of pathological change in the common carotid artery at the bifurcation and in the internal carotid artery beyond the bifurcation which could contribute to a reduced diastolic pressure as observed in primary open ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Characteristics and outcomes of COVID-19 patients hospitalized at a Central Hospital in Harare, 2020-2022

Journal of Interventional Epidemiology and Public Health
Introduction: In June 2021, Zimbabwe experienced a third COVID-19 wave characterized by a 3.5% case fatality rate compared to 1.5% in the first wave and 2.6% in the second wave. Sixty-eight percent of these deaths were among hospitalized patients.

Generators for primary closures of Galois fields

Finite Fields and Their Applications, 2003
Let \(q\) be a prime power, \(k\) and \(e\) positive integers and \((\mathbb F_q,\mathbb F_{q^k},\mathbb F_{q^{ek}})\) a tower of finite fields of order \(q\), \(q^k\) and \(q^{ek}\), respectively. Let \({\mathcal F}\) denote the set of triples \((q,k,e)\) for which, for every \(a\in \mathbb F_{q^k}\) normal over \(\mathbb F_q\) (i.e.\ \(\{a,a^q,\dots ...
