SSR molecular marker developments and genetic diversity analysis of Zanthoxylum nitidum (Roxb.) DC
Abstract Zanthoxylum nitidum (Roxb.) is a commonly used traditional Chinese medicine. However, the collection and protection of wild germplasm resources of Z. nitidum are still insufficient, and there is limited research on its genetic diversity and fingerprint. In the present study, 15 simple sequence repeat (SSR) markers were developed by genotyping based on multiplexed shotgun…

Genetic evidence for causal effects of leukocyte counts on risk for rheumatoid arthritis
Abstract Rheumatoid arthritis (RA) is an autoimmune disease characterized by the accumulation of leukocytes and inflammatory mediators within the synovial tissue. Leukocyte counts are proposed to play a role in the pathogenesis of RA. However, the causality remains unclear. To investigate the causal relationship between various leukocytes and RA by implementing two-sample univariable Mendelian Randomization…

What we actually know about aliens, according to science
GREEN BANK, W.Va. — It came from space, hurtling at tremendous speed: a mystery object, reddish, rocky, shaped like a cigar. Its velocity was so extreme it had to have come from somewhere far away, in the interstellar realm. The astronomers in Hawaii who spotted it in 2017 named it ‘Oumuamua, Hawaiian for “a messenger…

Temperature variation in caves and its significance for subterranean ecosystems
Abstract Climate change affects all ecosystems, but subterranean ecosystems are repeatedly neglected from political and public agendas. Cave habitats are home to unknown and endangered species, with low trait variability and intrinsic vulnerability to recover from human-induced disturbances. We studied the annual variability and cyclicity of temperatures in caves vis-à-vis surface in different climatic areas.…

Retroperitoneal totally endoscopic prosthetic repair of lumbar hernia
Abstract Lumbar hernia is a rare lateral abdominal wall hernia. Various surgical repair strategies have been recorded, but there is currently no unified standard. A Chinese surgeon recently revealed a novel technique for treating primary lumbar hernia called retroperitoneal totally endoscopic prosthetic repair (R-TEP). We have made a further exploration of this method and successfully…

A positive feedback loop regulation between NOTCH1 and USP11 in T-cell leukemia
To the Editor: NOTCH1 is a transmembrane receptor in a highly conserved signaling pathway that controls cell fate decisions in various organisms and tissues. In contrast, its dysregulation is associated with developmental disorders transformation [1]. NOTCH1 is composed of extracellular and intracellular domains. Ligand binding of NOTCH1 extracellular domain leads to two consecutive cleavage steps…

Muscle activity variability patterns and stride to stride fluctuations of older adults are positively correlated during walking
Abstract It has been found that fractal-like patterns are present in the temporal structure of the variability of healthy biological rhythms, while pathology and disease lead to their deterioration. Interestingly, it has recently been suggested that these patterns in biological rhythms are related with each other, reflecting overall health or lack of it, due to…
