Molecular Basis Behind Inability of Mitochondrial Holocytochrome c Synthase to Mature Bacterial Cytochromes: Defining a Critical Role for Cytochrome c Alpha Helix-1 Cell Biology
Mitochondrial holocytochrome c synthase (HCCS) is required for cytochrome c (cyt c) maturation and therefore respiration. HCCS efficiently attaches heme via two thioethers to CXXCH of mitochondrial but not bacterial cyt c, even though they are functionally conserved. This inability is due to residues in the bacterial cyt c N terminus, but the molecular basis… Continue reading Molecular Basis Behind Inability of Mitochondrial Holocytochrome c Synthase to Mature Bacterial Cytochromes: Defining a Critical Role for Cytochrome c Alpha Helix-1 Cell Biology

Cortical Entropy, Mutual Information and Scale-Free Dynamics in Waking Mice
Some neural circuits operate with simple dynamics characterized by one or a few well-defined spatiotemporal scales (e.g. central pattern generators). In contrast, cortical neuronal networks often exhibit richer activity patterns in which all spatiotemporal scales are represented. Such "scale-free" cortical dynamics manifest as cascades of activity with cascade sizes that are distributed according to a power-law. Theory and *in vitro* experiments suggest that information transmission among cortical circuits is optimized by scale-free dynamics. *In vivo* tests of this hypothesis hav... περισσότερα »
Foxp2 Regulates Identities and Projection Patterns of Thalamic Nuclei During Development
The molecular mechanisms underlying the formation of the thalamus during development have been investigated intensively. Although transcription factors distinguishing the thalamic primordium from adjacent brain structures have been uncovered, those involved in patterning inside the thalamus are largely unclear. Here, we show that Foxp2, a member of the forkhead transcription factor family, regulates thalamic patterning during development. We found a graded expression pattern of Foxp2 in the thalamic primordium of the mouse embryo. The expression levels of Foxp2 were high in the po... περισσότερα »

Representing multiple object weights: competing priors and sensorimotor memories.
When lifting an object, individuals scale lifting forces based on long-term priors relating external object properties (such as material and size) to object weight. When experiencing objects that are poorly predicted by priors, people rapidly form and update sensorimotor memories that can be used to predict an object's atypical size-weight relation in support of predictively scaling lift forces. With extensive experience lifting such objects, long-term priors, assessed using weight judgements, are gradually updated. The aim of the current study was to understand the formation and ... περισσότερα »
Membrane potential resonance frequency directly influences network frequency through electrical coupling
Oscillatory networks often include neurons that membrane potential resonance, a peak in the voltage amplitude as a function of current input at a nonzero (resonance) frequency (fres). Although fres has been correlated to the network frequency (fnet) in a variety of systems, a causal relationship between the two has not been established. We examine the hypothesis that combinations of biophysical parameters that shift fres, without changing other attributes of the impedance profile, also shift fnet in the same direction. We test this hypothesis, computationally and experimentally, i... περισσότερα »
Integration of autopatching with automated pipette and cell detection in vitro
Patch-clamp is the main technique for measuring electrical properties of individual cells. Since its discovery in 1976 by Neher and Sakmann, patch clamp has been instrumental in broadening our understanding of the fundamental properties of ion channels and synapses in neurons. The conventional patch-clamp method requires manual, precise positioning of a glass micropipette against the cell membrane of a visually-identified target neuron. Subsequently, a tight "giga-seal" connection between the pipette and the cell membrane is established, and suction is applied to establish the who... περισσότερα »
Glutamatergic drive facilitates synaptic inhibition of dorsal vagal motor neurons after experimentally-induced diabetes in mice
The role of central regulatory circuits in modulating diabetes-associated glucose dysregulation has only recently been under rigorous investigation. One brain region of interest is the dorsal motor nucleus of the vagus (DMV), which contains preganglionic parasympathetic motor neurons that regulate subdiaphragmatic visceral function. Previous research demonstrated that glutamatergic and GABAergic neurotransmission are independently remodeled after chronic hyperglycemia/hypoinsulinemia. However, glutamatergic circuitry within the dorsal brainstem impinges on GABAergic regulation of ... περισσότερα »
Contribution of intra-vestibular sensory conflict to motion sickness and dizziness in migraine disorders
Migraine is associated with enhanced motion sickness susceptibility and can cause episodic vertigo (vestibular migraine, VM), but the mechanisms relating migraine to these vestibular symptoms remain uncertain. We tested the hypothesis that the central integration of rotational cues (from the semicircular canals) and gravitational cues (from the otolith organs) is abnormal in migraine patients. A post-rotational tilt paradigm generated a conflict between the canal cues (which indicate the head is rotating) and the otolith cues (which indicate the head is tilted and stationary), and ... περισσότερα »
Oculomotor inhibition covaries with conscious detection
Saccadic eye movements occur frequently even during attempted fixation, but they halt momentarily when a new stimulus appears. Here we demonstrate that this rapid, involuntary "oculomotor freezing" reflex is yoked to fluctuations in explicit visual perception. Human observers reported the presence or absence of a brief visual stimulus while we recorded microsaccades, small spontaneous eye movements. We found that microsaccades were reflexively inhibited if and only if the observer reported seeing the stimulus, even when none was present. By applying a novel Bayesian classification... περισσότερα »
Optimal visuo-tactile integration for velocity discrimination of self-hand movements
Illusory hand movements can be elicited by a textured disk or a visual pattern rotating under one's hand, while proprioceptive inputs convey immobility information (Blanchard et al., 2013). Here we investigated whether visuo-tactile integration can optimize velocity discrimination of illusory hand movements in line with Bayesian predictions. We induced illusory movements in fifteen volunteers by visual and/or tactile stimulation, delivered at six angular velocities. The participants had to compare hand illusion velocities with a 5°/s hand reference movement in an alternative force... περισσότερα »
Spontaneous activity and functional connectivity in the developing cerebellorubral system
The development of the cerebellar system depends in part upon the emergence of functional connectivity in its input and output pathways. Characterization of spontaneous activity within these pathways provides insight into their functional status in early development. Here we recorded extracellular activity from the interpositus nucleus (IP) and its primary downstream target, the red nucleus (RN), in unanesthetized rats at postnatal days (P) 8 and P12, a period of dramatic change in cerebellar circuitry. The two structures exhibited state-dependent activity patterns and age-related... περισσότερα »
The compensatory interaction between motor unit firing behavior and muscle force during fatigue
Throughout the literature different observations of motor unit firing behavior during muscle fatigue have been reported and explained with varieties of conjectures. The disagreement amongst previous studies has resulted in part from the limited number of available motor units, and from the misleading practice of grouping motor unit data across different subjects, contractions, and force levels. To establish a more clear understanding of motor unit control during fatigue we investigated the firing behavior of motor units from the Vastus Lateralis muscle of individual subjects durin... περισσότερα »
Cognitive dysfunction in Duchenne Muscular Dystrophy: a possible role for neuromodulatory immune molecules.
Duchenne Muscular Dystrophy (DMD) is an X chromosome-linked disease characterized by progressive physical disability, immobility and premature death in affected boys. Underlying the devastating symptoms of DMD is the loss of dystrophin, a structural protein which connects the extracellular matrix to the cell cytoskeleton and provides protection against contraction-induced damage in muscle cells, leading to chronic peripheral inflammation. However, dystrophin is also expressed in neurons within specific brain regions, including the hippocampus, a structure associated with learning ... περισσότερα »
Pre-saccadic motion integration * between current and future retinotopic locations of attended objects
Object tracking across eye movements is thought to rely on pre-saccadic updating of attention between the object's current and its "remapped" location (i.e., the post-saccadic retinotopic location). Here we report evidence for a bi-focal, pre-saccadic sampling between these two positions. While preparing a saccade, participants viewed four spatially separated random dot kinematograms, one of which was cued by a colored flash. They reported the direction of a coherent motion signal at the cued location while a second signal occurred simultaneously either at the cue's remapped locat... περισσότερα »
Model-based stability assessment of ventilatory control in overweight adolescents with obstructive sleep apnea during NREM sleep
Obstructive sleep apnea (OSA) involves the interplay of several different factors such as an unfavorable upper airway anatomy, deficiencies in pharyngeal muscle responsiveness, a low arousal threshold, and ventilatory control instability. Although the stability of ventilatory control has been extensively studied in adults, little is known about its characteristics in the pediatric population. In this study, we developed a novel experimental setup that allowed us to perturb the respiratory system during natural non-rapid eye movement (NREM) sleep conditions by manipulating the insp... περισσότερα »
Effect of eccentric exercise with reduced muscle glycogen on plasma interleukin-6 and neuromuscular responses of musculus quadriceps femoris
Eccentric exercise can result in muscle damage and interleukin-6 (IL-6) secretion. Glycogen availability is a potent stimulator of IL-6 secretion. We examined effects of eccentric exercise in a low-glycogen state on neuromuscular function and plasma IL-6 secretion. Twelve active men (23 ± 4 yr, 179 ± 5 cm, 77 ± 10 kg, means ± SD) completed two downhill treadmill runs (gradient, –12%, 5 x 8 min; speed, 12.1 ± 1.1 km/h) with normal (NG) and reduced muscle glycogen (RG) in randomized order and at least 6 wk apart.

Voluntary physical activity abolishes the proliferative tumor growth microenvironment created by adipose tissue in animals fed a high fat diet
The molecular mechanisms behind the obesity-breast cancer association may be regulated via adipokine secretion by white adipose tissue. Specifically, adiponectin and leptin are altered with adiposity and exert antagonistic effects on cancer cell proliferation. We set out to determine whether altering adiposity in vivo via high fat diet (HFD) feeding changed the tumor growth supporting nature of adipose tissue and whether voluntary physical activity (PA) could ameliorate these HFD-dependent effects. We show that conditioned media (CM) created from the adipose tissue of HFD fed anim... περισσότερα »
Neither load nor systemic hormones determine resistance training-mediated hypertrophy or strength gains in resistance-trained young men
We reported, using a unilateral resistance training (RT) model, that training with high or low loads (mass per repetition) resulted in similar muscle hypertrophy and strength improvements in RT-naïve subjects. Here we aimed to determine whether the same was true in men with previous RT experience using a whole-body RT program and whether postexercise systemic hormone concentrations were related to changes in hypertrophy and strength. Forty-nine resistance-trained men (23 ± 1 yr, mean ± SE) performed 12 wk of whole-body RT. Subjects were randomly allocated into a higher-repetition ... περισσότερα »

Degradation and ecotoxicity of dye Reactive Black 5 after reductive-oxidative process
Abstract This research paper describes the study of a reduction-oxidation system using commercial steel wool (Fe0) and H2O2 for degradation of the dye Reactive Black 5 and aromatic compounds in water. The reductive process alone allowed the almost complete removal of color (97 ± 1 %) after 60 min of reaction. The decrease in spectral area (*λ* = 599 nm) associated with the chromophore group indicates breakage of the azo bonds. Moreover, the significant change in UV spectra can be associated with the formation of aromatic amines. Regarding the transformation products, a spectrophot... περισσότερα »
