Abstract Left ventricular non-compaction cardiomyopathy (LVNC) is one of the most common inherited cardiovascular diseases. The genetic backgrounds of most LVNC patients are not fully understood. We collected clinical data, family histories, and blood samples and performed genetic analysis using next-generation sequencing (NGS) from a Chinese family of 15 subjects. Clinically LVNC affected subjects showed marked cardiac phenotype heterogeneity. We found that these subjects with LVNC carried a missense heterozygous genetic mutation c.905G>A (p.R302Q) in...

Femtosecond laser filamentation propagating tens of meters to several kilometers with high intensity in the atmosphere has been demonstrated as a powerful tool for remote sensing. In contrast to the refractive systems, the reflective optical systems possess a variety of advantages including broad bandwidth, large aperture, light weight and low energy loss. However, astigmatic aberration is inevitably introduced by off-axis reflective mirrors. It can greatly affect the filament quality, which is critical for exciting and...

Abstract Age-related macular degeneration (AMD), a progressive chronic disease of the central retina, is a leading cause of blindness worldwide.

Methods Summary statistics from genome-wide association studies (GWAS) for VEGF and VTE...

Femtosecond laser micromachining has been considered as a powerful tool for fabricating versatile fiber devices and received increasing attention in recent years. Here, we report on a compact sensor by integrating a bridge-like waveguide inside a single-mode fiber to construct an in-line Mach-Zehnder interferometer and then inscribing a second-order Bragg grating in the core of the same fiber. The interference dip shows good performance in torsion sensing -- the maximum torsion sensitivity of 1.5773 nm/(rad/m),...

Gustatory systems in phytophagous insects are used to perceive feeding stimulants and deterrents and are involved in insect decisions to feed on particular plants. During the process, gustatory receptors (Gr) can recognize diverse phytochemicals and provide a molecular basis for taste perception. The silkworm, as a representative Lepidoptera species, has developed a strong feeding preference for mulberry leaves. The mulberry-derived flavonoid glycoside, isoquercetin, is required to induce feeding behaviours. However, the corresponding Gr for isoquercetin...
