Hand stereotypies are considered a hallmark of Rett syndrome (RTT) and usually described as symmetric movements at the midline. However, related pathologies may show same type involuntary movement. Furthermore, patients with RTT also have other localizations that less well characterized.We analyzed in 83 RTT, 53 30 without mutation detected MECP2 gene. Patients were observed videotaped always by pediatric neurologist. Stereotypies classified, data submitted to statistical analysis for...
Binary mutual diffusion coefficients (interdiffusion coeffcients) have been measured for aqueous solutions of β-cyclodextrin (β-CD) at concentrations from (0.002 to 0.008) mol·dm-3. The effect temperature, (298.15 312.15) K, was also analyzed. concentration dependence D is discussed on the basis Hartley's equation. activation energy process, 18719 J·mol-1, calculated data different temperatures. This in good agreement with that estimated using Stokes−Einstein equation (18644 J·mol-1)....
Congenital muscular dystrophy type 1A (MDC1A) is caused by mutations in the LAMA2 gene encoding laminin-alpha2. We describe molecular study of 26 patients with clinical presentation, magnetic resonance imaging and/or laminin-alpha2 expression muscle, compatible MDC1A. The combination full genomic sequencing and complementary DNA analysis led to particularly high mutation detection rate 96% (50/52 disease alleles). Besides 22 undocumented polymorphisms, 18 different were identified course...

A metodologia consistiu em integrativa realizada nas bases dados Scientific Electronic Library Online (SCIELO), Cochrane Medline, descritores ciências saúde relacionados ao tema, como “Laparoscopy”, “Gynecology” “Gynecological...
INTRODUÇÃO: A violência sexual contra crianças gera consequências duradouras, afetando sua saúde mental e capacidade de construir relacionamentos saudáveis. Este estudo visa explorar os impactos, identificar fatores risco sugerir intervenções para melhorar a das vítimas. METODOLOGIA: metodologia consiste em uma revisão bibliográfica utilizando plataforma BVS MEDLINE, inglês no ano 2024, totalizando 92 artigos avaliação inicial. RESULTADOS E DISCUSSÕES: Após análise criteriosa, foram...
In combat sports, precise technique evaluation is crucial for performance optimization; however, traditional systems evaluating kick are frequently unreasonably complicated and costly. This study offers a useful accessible substitute by introducing contact mat-based tool that measures the roundhouse kick’s execution time during both attack recovery phases demonstrating its reliability. The experimental sessions involved 16 male Shotokan karate athletes (age: 25.6 ± 7.1 years; height: 1.74...

Binary mutual diffusion coefficients measured by the Taylor dispersion method are reported for aqueous solutions of α-cyclodextrin (α-CD), 2-hydroxypropyl-α-cyclodextrin (HP-α-CD), and 2-hydroxypropyl-β-cyclodextrin (HP-β-CD) at concentrations from (0.002 to 0.010) mol·dm-3 temperatures (298.15 312.15) K. The hydrodynamic radius activation energy α-CD, HP-α-CD, HP-β-CD calculated experimental results. In addition, Hartley equation used estimate activity HP-β-CD.
Values of binary mutual diffusion (interdiffusion) coefficients, obtained by using the Taylor dispersion method, for aqueous solutions γ-cyclodextrin in concentration range from (0.002 to 0.010) mol·dm−3 and temperatures (298.15 310.15) K are reported. From these experimental results, hydrodynamic radius values estimated. Also, measured coefficients used with both Hartley's Gordon's equations estimate activity γ-cyclodextrin. These studies complemented some density viscosity measurements,...
A Taylor dispersion method is used to measure ternary multicomponent diffusion coefficients of three-component liquid systems. Ternary mutual measured by this (D11, D22, D12, and D21) are reported for aqueous solutions β-cyclodextrin (β-CD) + caffeine at 298.15 K carrier concentrations from (0.000 0.010) mol·dm−3, each solute, respectively. These have been having in mind a better understanding the structure these systems thermodynamic behavior cyclodextrin solution.
Knowledge of mass transport parameters, diffusion, and viscosity hyaluronic acid (HA) in the presence cyclodextrins is considerable importance for areas such as food packaging drug delivery, among others. Despite a number studies investigating functionalization HA or corresponding sodium salt by cyclodextrins, only few have reported effect on these oligosaccharides. Here, we report tracer binary ternary interdiffusion coefficients hyaluronate (NaHy) water aqueous β-cyclodextrin solutions....

Binary mutual diffusion coefficients measured by the Taylor dispersion method in two different laboratories (University of Naples, Federico II, Italy, and University Coimbra, Portugal) are reported for aqueous solutions isoniazid at concentrations from (0.000 to 0.100) mol·dm−3 temperatures (298.15 310.15) K. The hydrodynamic radii solution calculated experimental results. In addition, Hartley equation used estimate activity both temperatures.
