Anticipatory and Compensatory Postural Adjustments in Sitting and Standing Positions During Functional Activities in Children With Cerebral Palsy.

Background And Purpose: Anticipatory postural adjustments (APA) and compensatory postural adjustments (CPA) have played a vital role in postural control since early childhood, which is critical to accomplishing activities in daily life. However, literature indicated dissimilarities and inconsistencies in APA and CPA analysis in sitting and standing positions in children with Cerebral Palsy (CP). Thus, this study analyzed the changes in postural control (APA and CPA) through the postural muscles [rectus abdominis (RA) and erector spinae (ES)] in both standing and sitting positions during functional activities (grasping a ball) in children with CP.

TDP-43 Cryptic RNAs in Perry Syndrome: Differences across Brain Regions and TDP-43 Proteinopathies.

Background: Perry syndrome (PS) is a rare and fatal hereditary autosomal dominant neurodegenerative disorder caused by mutations in dynactin (DCTN1). PS brains accumulate inclusions positive for ubiquitin, transactive-response DNA-binding protein of 43 kDa (TDP-43), and to a lesser extent dynactin.

Objectives: Little is known regarding the contributions of TDP-43, an RNA binding protein that represses cryptic exon inclusion, in PS.

'Nomadic' Hematopoietic Stem Cells Navigate the Embryonic Landscape.

Hematopoietic stem cells are a unique population of tissue-resident multipotent cells with an extensive ability to self-renew and regenerate the entire lineage of differentiated blood cells. Stem cells reside in a highly specialized microenvironment with surrounding supporting cells, forming a complex and dynamic network to preserve and maintain their function. The survival, activation, and quiescence of stem cells are largely influenced by niche-derived signals, with aging niche contributing to a decline in stem cell function.

Observation of quantum oscillations near the Mott-Ioffe-Regel limit in CaAs.

The Mott-Ioffe-Regel limit sets the lower bound of the carrier mean free path for coherent quasiparticle transport. Metallicity beyond this limit is of great interest because it is often closely related to quantum criticality and unconventional superconductivity. Progress along this direction mainly focuses on the strange-metal behaviors originating from the evolution of the quasiparticle scattering rate, such as linear-in-temperature resistivity, while the quasiparticle coherence phenomena in this regime are much less explored due to the short mean free path at the diffusive bound.

Engineering the Reaction Pathway of a Non-heme Iron Oxygenase Using Ancestral Sequence Reconstruction.

Non-heme iron (Fe), α-ketoglutarate (α-KG)-dependent oxygenases are a family of enzymes that catalyze an array of transformations that cascade forward after the formation of radical intermediates. Achieving control over the reaction pathway is highly valuable and a necessary step toward broadening the applications of these biocatalysts. Numerous approaches have been used to engineer the reaction pathway of Fe/α-KG-dependent enzymes, including site-directed mutagenesis, DNA shuffling, and site-saturation mutagenesis, among others.

The characteristics of formula milk marketing on health system: a qualitative study from Beijing and Jinan in China.

Background: Breastmilk is widely regarded as the healthiest choice for both infants and mothers due to its numerous advantages over formula, such as higher concentrations of essential nutrients and antibodies, easier digestion, and superior taste. The World Health Organization International Code of Marketing of Breast-milk Substitutes was adopted over 40 years ago to mitigate the effects of infant formula marketing on a woman's decision to breastfeed. Yet, the commercial formula milk industry has continued to market their products aggressively and through an increasing variety of social media channels.

Rational engineering of an antimalarial peptide with enhanced proteolytic stability and preserved parasite invasion inhibitory activity.

We describe rational chemical engineering to enhance the proteolytic stability of a chimeric peptide using a combination of unique strategies that involve the incorporation of a series of d-amino acids into the parent l-peptide sequence and restricting the conformational freedom of the peptide by covalent stitching. We hypothesize that replacing a stretch of sequence of an unstructured peptide motif with d-amino acids would increase its proteolytic stability without significantly affecting its affinity to the target protein. Also, considering the C-C distances, replacing an appropriate pair of residues with cysteine to form an additional disulfide bond in the molecule would provide additional stability to the engineered peptide.

Electrochemical Reduction of Nitrogen to Ammonia Using Zinc Telluride.

Electrosynthesis of ammonia (NH), an important constituent molecule of various commercial fertilizers, is a promising and sustainable alternative strategy compared with the century-old Haber-Bosch process. Herein, zinc telluride (ZnTe) is demonstrated as an efficient electrocatalyst for reducing nitrogen (N) under ambient conditions to NH. In this simple chemical strategy, Zn preferentially binds N over hydrogen (H), and Te, by virtue of its superior electronic properties, enhances the electrocatalytic activity of ZnTe.

Ancestral Sequence Reconstruction to Enable Biocatalytic Synthesis of Azaphilones.

Biocatalysis can be powerful in organic synthesis but is often limited by enzymes' substrate scope and selectivity. Developing a biocatalytic step involves identifying an initial enzyme for the target reaction followed by optimization through rational design, directed evolution, or both. These steps are time consuming, resource-intensive, and require expertise beyond typical organic chemistry.

Uncertainty Quantification of the Effect of Variable Conductivity in Ventricular Fibrotic Regions on Ventricular Tachycardia.

Ventricular tachycardia (VT) is a life-threatening cardiac arrhythmia for which a common treatment pathway is electroanatomical mapping and ablation. Recent advances in both noninvasive ablation techniques and computational modeling have motivated the development of patient-specific computational models of VT. Such models are parameterized by a wide range of inputs, each of which is associated with an often unknown amount of error and uncertainty.

Uncertainty Quantification of Fiber Orientation and Epicardial Activation.

Predictive models and simulations of cardiac function require accurate representations of anatomy, often to the scale of local myocardial fiber structure. However, acquiring this information in a patient-specific manner is challenging. Moreover, the impact of physiological variability in fiber orientation on simulations of cardiac activation is poorly understood.

Capturing the Influence of Conduction Velocity on Epicardial Activation Patterns Using Uncertainty Quantification.

Individual variability in parameter settings, due to either user selection or disease states, can impact accuracy when simulating the electrical behavior of the heart. Here, we aim to test the impact of inevitable uncertainty in conduction velocities (CVs) on the output of simulations of cardiac propagation, given three stimulus locations on the left ventricular (LV) free wall. To understand the role of physiological variability in CV in simulations of cardiac activation, we generated detailed maps of the variability in propagation simulations by implementing bi-ventricular activation simulations and quantified the effects by deploying robust uncertainty quantification techniques based on polynomial chaos expansion (PCE).
