Profile of the body surface proteolytic systém in Apis mellifera quee

Czech Journal of Animal Science, 2011
The proteolytic system on the body surface of the honey bee has been insufficiently researched. In this study the body surface proteolytic activity was examined in queens at various developmental stages (eggs, larvae, pupae and imagines) in different ...

The Vortex Surface in a Three-Body Quantum System

Atoms, 2023
Vortices are structures known in our daily lives and observed in a wide variety of systems, from cosmic to microscopic scales. Relatively recent studies showed that vortices could also appear in simple quantum systems.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

FEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Geographical Distribution of the Body-Weight/Body-Surface Ratio [PDF]

Nature, 1950
IN the course of biometrical work concerning twenty different human samples—the individual figures partly obtained by myself and partly taken from other sources—I have found the following values for the body-weight/body-surface ratio (kgm./m.2):

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.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Body Movement along the Surface of an Inertial Conveyor Chute under Combined Friction

Журнал інженерних наук
The main problem of inertial conveyors is the presence of friction between the load and the conveyor chute when the load moves in the required direction. Transverse oscillations of the chute or other force factors are commonly used to reduce the force of

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Normal reference ranges for aortic diameters in preterm infants

Journal of the Saudi Heart Association, 2018
Objective: To establish normal reference ranges and Z-scores for aortic diameters in preterm infants according to the body surface area and assess their correlation with body weight, body surface area, and gestational age.
