Monte Carlo simulation with fixed steplength for diffusion processes in nonhomogeneous media [PDF]

, 2013
Monte Carlo simulation is one of the most important tools in the study of diffusion processes. For constant diffusion coefficients, an appropriate Gaussian distribution of particle's steplengths can generate exact results, when compared with integration ...

Risk Factors and Predictive Models for Sarcopenia in Older Adults

AGING MEDICINE, EarlyView.
Independent risk factors for sarcopenia identified by Lasso regression and logistic regression in the study were BMI, prealbumin, albumin/globulin ratio (A/G ratio), serum creatinine, and phosphorus. These factors were used to construct a nomogram model and a decision tree model. Both models showed effectiveness in predicting sarcopenia in older adults,

Involvement of cyclic AMP in multiple, excitatory actions of biogenic amines on the cardiac ganglion of the horseshoe crab Limulus polyphemus [PDF]

, 1990
Cyclic AMP appears to be involved in several excitatory actions of amines on neurones of the Limulus cardiac ganglion. Amines selectively increase levels of cardiac ganglion cyclic AMP with a magnitude and time course similar

The effects of age and ganglioside composition on the rate of motor nerve terminal regeneration following antibody-mediated injury in mice [PDF]

, 2013
Gangliosides are glycosphingolipids highly enriched in neural plasma membranes, where they mediate a diverse range of functions and can act as targets for auto-antibodies present in human immune-mediated neuropathy sera.

Design, Modeling, and Control of a Soft Robotic Diaphragm‐Assist Device in a Respiratory Simulator

Advanced Intelligent Systems, EarlyView.
A soft robotic diaphragm‐assist device using fabric‐based pneumatic actuators with a 2‐step control system to optimize synchronization and support is introduced. This system can detect the initiation of breathing to trigger assistance and regulate pressures to provide the correct level of inhalation augmentation. Validation and testing are completed on

Neuromuscular synaptic transmission in aged ganglioside-deficient mice [PDF]

, 2011
Gangliosides are sialylated glycosphingolipids that are present in high density on neuronal membranes, especially at synapses, where they are assumed to play functional or modulating roles.

Patient With Prolidase Deficiency due to an Homozygous PEPD Variant, Induced by Paternal Uniparental Isodisomy of Chromosome 19

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Uniparental disomy (UPD) is a rare phenomenon in which both copies of a chromosome are inherited from a single parent. This can lead to genomic imprinting disorders and recessive disorders due to the presence of recessive pathogenic variants in both alleles. Additionally, depending on the mechanisms by which UPD occurs, mosaic aneuploidies may

Positional Relationship Between the Orbicularis Oculi and Zygomaticus Complex Muscles by Ultrasonography: New Anatomical Insights for Crow's Feet Injection

Clinical Anatomy, EarlyView.
ABSTRACT The orbicularis oculi muscle (OOc) is strongly associated with facial aging as its contraction causes the formation of crow's feet. Botulinum neurotoxin (BoNT) injection is a representative treatment targeting muscle. The aim of this study was to demonstrate the anatomical relationship between the OOc and the zygomaticus complex muscles, and ...
