Quantifying Kinematic Tremor in an NGLY1-Deficient Individual: A Case study

引用

Case Reports in Clinical Medicine 2024年第1期13卷 25-36页

作者： Brock Futrell Christopher alexander Malaya Dacia Martinez Diaz Christian Alfaro Hannah Elizabeth Gustafson subhalakshmi Chandrasekaran Rhea Mohan Phatak Bernhard suter Charles shannon Layne Department of Health and Human Performance University of Houston Houston USA Center for Neuromotor and Biomechanics Research University of Houston Houston USA Department of Computer science and Engineering Texas A&M University College Station USA Blue Bird Circle Rett Center Texas Children’s Hospital Houston USA Baylor College of Medicine Houston USA Center for NeuroEngineering and Cognitive science University of Houston Houston USA

NGLY1 Deficiency is an autosomal recessive congenital disorder that has been identified in less than 100 individuals. Most individuals with NGLY1 Deficiency display hyperkinetic movement disorders, including choreiform, athetoid, dystonic myoclonic, dyskinetic, and dysmetric movements. Developing a consistent and concise consensus on the classification and evaluation of tremors is essential to forward the research and treatment of tremors. It has also been reported that some individuals with NGLY1 Deficiency demonstrate tremor, but such tremor has never been formally investigated. The primary objective of this study is to determine if an individual with NGLY1 Deficiency demonstrates an identifiable tremor during a series of arm movements and, if so, describe the frequency and power characteristics of that tremor. Arm movement kinematics were obtained using a 16-camera Vicon system, and time series trajectory waveforms for three planes of a marker placed on the hand were developed. Custom MATLAB scripts were utilized to compute Fast Fourier Transformations of the data within the identified waveform segments. A mean frequency of 2.30 Hz (sD = 1.05) with a mean power of 5.02 |P1(f)| (sD = 4.63) suggests that our participant’s kinematic data did display a persistent tremor in both hands across all tasks and movement planes. Analyses of the reaching hand and the non-reaching hand suggest the participant displayed an action tremor in both postural and intention (kinetic) tremors. Future directions should include assessing additional individuals with NGLY1 Deficiency to determine if the tremor is a distinguishable disorder behavior. Additionally, evaluating other anatomical sites, such as the elbow, head, and lower limbs, would provide further insights into the characteristics of this tremor.

Frontiers of Mechanical Engineering 2016年第1期11卷 95-100页

作者： alexander BELYAEV alexander sUKHANOV alexander TsVETKOV Institute of Applied Mathematics and Mechanics Saint-Petersburg Polytechnic University St. Petersburg 195251 Russia

This article addresses the problem in which a chain falls from a glass from some height. This phenomenon demonstrates a paradoxical rise of the chain over the glass. To explain this effect, an initial hypothesis and an appropriate theory are proposed for calculating the steady fall parameters of the chain. For this purpose, the modified Cayley ＇s problem of falling chain given its rise due to the centrifugal force of upward inertia is solved. Results show that the lift caused by an increase in linear density at the part of chain where it is being bent （the upper part） is due to the convergence of the chain balls to one another. The experiments confirm the obtained estimates of the lifting chain.

Varicocele management in the era of in vitro fertilization/intracytoplasmic sperm injection

引用

Asian Journal of Andrology 2016年第3期18卷 343-348,I0006,I0007页

作者： Piyush Pathak Aravind Chandrashekar Tariq s Hakky alexander W Pastuszak scott Department of Urology Baylor College of Medicine Houston TX USA scott Department of Urology Kaiser Permanente Riverside Medical Center Riverside CAUSA Advanced Uro ogy At anta GA USA scott Department of Urology Center for Reproductive Medicine Baylor College of Medicine Houston TX USA scott Department of Urology Baylor College of Medicine Houston TxUSA.

Varicocele is the most common surgically treatable cause of male infertility, and often results in alterations in semen parameters, sperm DNA damage, and changes to the seminal milieu. Varicocele repair can result in improvement in these parameters in the majority of men with clinical varicocele; data supporting repair in men with subclinical varicocele are less definitive. In couples seeking fertility using assisted reproductive technologies （ARTs）, varicocele repair may offer improvement in semen parameters and sperm health that can increase the likelihood of successful fertilization using techniques such as in vitro fertilization （IVF） or intracytoplasmic sperm injection （ICsI）, or may decrease the level of ART needed to achieve successful pregnancy. Male infertility is an indicator of general male health, and evaluation of the infertile male with an eye toward future health can facilitate optimal screening and treatment of these men. Furthermore, varicocele may represent a progressive lesion, offering an argument for its repair, although this is currently unclear.

Investigation of isotope composition of nuclear fragments with angular momentum and Coulomb effects in peripheral ^(84)Kr+ ^(112,124)sn collisons at 35 A MeV

引用

Nuclear science and Techniques 2015年第2期26卷 111-116页

作者： Nihal Buyukcizmeci Aysegul Ergun Hamide Imal Riza Ogul alexander s Botvina Department of Physics University of Seluk Institute for Nuclear Research Russian Academy of Sciences Frankfurt Institute for Advanced studies J.W. Goethe University

New theoretical calculations are performed to investigate the Coulomb proximity and angular momentum effects on multifragmentation picture for84Kr+112,124 sn collisions at an incident beam energy of 35 Me V/*** and isotopic distributions and the mean neutron-to-proton ratios of the fragments are reproduced within the microcanonical Markov chain calculations on the basis of statistical Multifragmentation Model. It is shown that the Coulomb interactions and angular momentum effects are very important to reproduce isotopic composition of nuclear fragments in peripheral heavy-ion collisions at Fermi energies. Our results imply that it is possible to investigate in laboratories the modification of structure parameters of fragments, such as the symmetry energy coefficient, at subnuclear densities in dense environment of other species.
