Trisomy 13 and 18 (T 13/18) are rare chromosomal abnormalities associated with high morbidity and mortality. Improved survival rates and increased prevalence of aggressive medical intervention have resulted in families and physicians holding different perspectives regarding the appropriate management of children with T 13/18. Families were invited for open-ended interviews regarding their experiences with the medical care of a child with T 13/18 over the past 5 years. Seven of 33 invited families were surveyed; those who had spent more than 40 days in the hospital were most likely to accept the invitation (OR 8...

Microglia, the resident immune cells of the CNS, are primary regulators of the neuroimmune response to injury. Type I interferons (IFNs), including the IFNαs and IFNβ, are key cytokines in the innate immune system. Their activity is implicated in the regulation of microglial function both during development and in response to neuroinflammation, ischemia, and neurodegeneration. Data from numerous studies in multiple sclerosis (MS) and stroke suggest that type I IFNs can modulate the microglial phenotype, influence the overall neuroimmune milieu, regulate phagocytosis, and affect blood-brain barrier integrity...

For better welding quality, accurate path teaching for actuators must be achieved before welding. Due to machining errors, assembly errors, deformations, etc., the actual groove position may be different from the predetermined path. Therefore, it is significant to recognize the actual groove position using machine vision methods and perform an accurate path teaching process. However, during the teaching process of a narrow butt joint, the existing machine vision methods may fail because of poor adaptability, low resolution, and lack of 3D information...

Myogenic precursors are myoblasts that have a potency to differentiate into muscle fibers on injury and maintain the regenerative power of skeletal muscle. However, the roles of exogenous nitric oxide (NO) in muscle development and myoblast differentiation are largely unknown. Therefore, in this study, we examined the effects of exogenous NO generated by a microwave plasma torch on rat myoblastic L6 cell proliferation and differentiation. We observed that the differentiation of L6 myogenic precursor cells into myotubes was significantly enhanced after NO treatment...

Arc sensors have been used in seam tracking and widely studied since the 80s and commercial arc sensing products for T and V shaped grooves have been developed. However, it is difficult to use these arc sensors in narrow gap welding because the arc stability and sensing accuracy are not satisfactory. Pulse gas melting arc welding (P-GMAW) has been successfully applied in narrow gap welding and all position welding processes, so it is worthwhile to research P-GMAW arc sensing technology. In this paper, we derived a linear mathematical P-GMAW model for arc sensing, and the assumptions for the model are verified through experiments and finite element methods...

The molecular fingerprinting of intact fruit samples combined with statistical data analysis can allow the assessment of fruit quality and location of origin. Herein, microwave plasma torch desorption ionization mass spectrometry (MPT-MS) was applied to produce molecular fingerprints for the juice sac and exocarp of navel oranges cultivated in three closely located habitats, and the mass spectrometric fingerprints were differentiated by principal component analysis (PCA). Because of the relatively high temperature and high ionization efficiency of MPT, the volatile aroma compounds and semivolatile chemicals in the navel oranges were sensitively detected and confidently identified by collision induced dissociation (CID)...

Infection with Listeria monocytogenes during pregnancy is associated with miscarriage, preterm birth, and neonatal complications, including sepsis and meningitis. While the risk of these conditions is thought to be greatest during the third trimester of pregnancy, the determinants of fetoplacental susceptibility to infection, the contribution of gestational age, and the in vivo progression of disease at the maternal-fetal interface are poorly understood. We developed a nonhuman primate model of listeriosis to better understand antecedents of adverse pregnancy outcomes in early pregnancy...
