Navigating Home Language Practice for Children With Disabilities: Insights From Korean-American Mothers\u27 Online Communications
This study explores the home language practice (HLP) of Korean-American mothers with children who have developmental disabilities, including autism spectrum disorder. Data was collected from an online forum where these mothers discussed their experiences and decision-making processes following their child\u27s diagnosis. Thematic analysis was conducted on the collected data to identify and develop themes related to their experiences. The study\u27s framework is based on family-centered practices, emphasizing the importance of equal partnerships, cultural responsiveness, and information sharing between families and early intervention and early childhood special education (EI/ECSE) professionals. Factors that influence HLP decisions include mothers\u27 perceptions of disabilities, professional advice, and children’s intervention progress. The study highlights the vital role of EI/ECSE professionals in sharing current research findings, their experiences with culturally and linguistically diverse (CLD) families, and the long-term outcomes of families that chose bilingual or single-language environments. By offering this information, professionals can assist parents in making informed decisions about their child\u27s HLP. Furthermore, the study emphasizes the value of online communities for CLD parents and the need for professionals to engage with these communities to provide accurate information on bilingualism for children with disabilities. Collaborating with ethnolinguistic communities and establishing parent support groups can create a nurturing environment for parents navigating EI/ECSE services for their children
THREE DIMENSIONAL SMOOTHING TECHNIQUES USING QUATERNIONS APPLIED TO GAIT
The purpose of this study was to implement a three-dimensional (3D) technique for smoothing gait analysis data. Three dimensional smoothing is problematic as it relies on one-dimensional smoothing techniques that are ill-posed to preserve the integrity of the real, raw data. Since Davis et al, (1991) method many researchers (e.g. Baker, 2006) have emphasized the problems of three dimensional gait analysis
CONSENSUS DEFINITION-BASED CUTOFFS OF HIGH ON-TREATMENT PLATELET REACTIVITY: VALIDATION BETWEEN LIGHT TRANSMITTANCE AND MULTIPLE ELECTRODE AGGREGOMETRIES
Palladium Catalysts for Dehydrogenation of Ammonia Borane with Preferential B−H Activation
Cationic Pd(II) complexes catalyzed the dehydrogenation of ammonia borane in the most efficient manner with the release of 2.0 equiv of H_2 in less than 60 s at 25 °C. Most of the hydrogen atoms were obtained from the boron atom of the ammonia borane. The first step of the dehydrogenation reaction was elaborated using density functional theory calculations
Case report: Spontaneous abortion of monoamniotic twins at the third trimester of pregnancy in Camelus dromedarius
Monoamniotic twins develop when a blastocyst spontaneously splits its progenitor cells, and each group of progenitor cells independently grows to become an individual. It is the rarest type of twin pregnancy and usually has significant developmental or congenital abnormalities, a higher rate of abortion, perinatal morbidity, and mortality. There is no information regarding monoamniotic twins in livestock species. Here, we reported a spontaneous abortion of monoamniotic twins in a dromedary camel at 278 days of gestation. Gonadorelin acetate (100 μg) was injected intramuscularly to induce ovulation in the recipient. A 7 days-old embryo produced by somatic cell nuclear transfer was transferred transcervically to the recipient. Early pregnancy was confirmed by an elevated level of serum progesterone followed by ultrasonography at 22 and 44 days after embryo transfer. A single sac was observed on 22 days while twins were evident 44 days after embryo transfer. Pregnancy was periodically monitored by the tail-up phenomenon. A ruptured fetal sac was observed on the ground having two fetuses. On autopsy, full-grown fetuses were found. Their bodies were separated. There was no congenital anomaly or any malformation in the fetuses. According to the reported chronology in human twins, we hypothesized that the blastocyst splitted before 13 days as it was monoamniotic and not conjoined. If the embryo splits within 4 to 8 days, it develops two amniotic sacs, and splitting after 13 days develops conjoined fetuses. To the authors’ knowledge, this is the first reported case of monoamniotic twin abortion in dromedary camels. This report will increase awareness among practicing veterinarians and camel breeders about twin abortions
Respiratory Syncytial Virus-Like Nanoparticle Vaccination Induces Long-Term Protection Without Pulmonary Disease by Modulating Cytokines and T-cells Partially Through Alveolar Macrophages
The mechanisms of protection against respiratory syncytial virus (RSV) are poorly understood. Virus-like nanoparticles expressing RSV glycoproteins (eg, a combination of fusion and glycoprotein virus-like nanoparticles [FG VLPs]) have been suggested to be a promising RSV vaccine candidate. To understand the roles of alveolar macrophages (AMs) in inducing long-term protection, mice that were 12 months earlier vaccinated with formalin-inactivated RSV (FI-RSV) or FG VLPs were treated with clodronate liposome prior to RSV infection. FI-RSV immune mice with clodronate liposome treatment showed increases in eosinophils, plasmacytoid dendritic cells, interleukin (IL)-4+ T-cell infiltration, proinflammatory cytokines, chemokines, and, in particular, mucus production upon RSV infection. In contrast to FI-RSV immune mice with severe pulmonary histopathology, FG VLP immune mice showed no overt sign of histopathology and significantly lower levels of eosinophils, T-cell infiltration, and inflammatory cytokines, but higher levels of interferon-γ, which are correlated with protection against RSV disease. FG VLP immune mice with depletion of AMs showed increases in inflammatory cytokines and chemokines, as well as eosinophils. The results in this study suggest that FG nanoparticle vaccination induces long-term protection against RSV and that AMs play a role in the RSV protection by modulating eosinophilia, mucus production, inflammatory cytokines, and T-cell infiltration
