Control of intracellular pH and bicarbonate by CO2 diffusion into human sperm

open access: yesNature Communications, 2023
The reaction of CO2 with H2O to form bicarbonate (HCO3 −) and H+ controls sperm motility and fertilization via HCO3 −-stimulated cAMP synthesis. A complex network of signaling proteins participates in this reaction.

Multifocal imaging for precise, label-free tracking of fast biological processes in 3D

open access: yesNature Communications, 2021
Multifocal imaging suffers from a number of limitations. Here the authors report an open-source 3D reconstruction algorithm to enable label-free tracking of spherical and filamentous structures which they use to characterise fluid flow and flagellar ...

Thermodynamic limits to information harvesting by sensory systems

open access: yes, 2015
In view of the relation between information and thermodynamics we investigate how much information about an external protocol can be stored in the memory of a stochastic measurement device given an energy budget.

Neurons with stereotyped and rapid responses provide a reference frame for relative temporal coding in primate auditory cortex [PDF]

open access: yes, 2012
The precise timing of spikes of cortical neurons relative to stimulus onset carries substantial sensory information. To access this information the sensory systems would need to maintain an internal temporal reference that reflects the precise stimulus ...

Deletion of Tsc2 in nociceptors reduces target innervation, ion channel expression, and sensitivity to heat [PDF]

open access: yes, 2018
The mechanistic target of rapamycin complex 1 (mTORC1) is known to regulate cellular growth pathways, and its genetic activation is sufficient to enhance regenerative axon growth following injury to the central or peripheral nervous systems.

Nutritional and Behavioral Intervention for Long‐Term Childhood Acute Leukemia Survivors With Metabolic Syndrome

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Metabolic syndrome (MetS) is a common complication in survivors of childhood acute lymphoblastic and myeloid leukemia (AL), and a major risk factor for premature cardiovascular disease, type‐2‐diabetes, and metabolic dysfunction‐associated steatotic liver disease (MASLD).

Sensory capacity: an information theoretical measure of the performance of a sensor

open access: yes, 2016
For a general sensory system following an external stochastic signal, we introduce the sensory capacity. This quantity characterizes the performance of a sensor: sensory capacity is maximal if the instantaneous state of the sensor has as much information

Biologically Inspired Feedback Design for Drosophila Flight [PDF]

open access: yes, 2007
We use a biologically motivated model of the Drosophila's flight mechanics and sensor processing to design a feedback control scheme to regulate forward flight.
