Genetic basis of camouflage in an alpine plant and its long-term co-evolution with an insect herbivore.

Camouflage through colour change can involve reversible or permanent changes in response to cyclic predator or herbivore pressures. The evolution of background matching in camouflaged phenotypes partly depends on the genetics of the camouflage trait, but this has received little attention in plants. Here we clarify the genetic pathway underlying the grey-leaved morph of fumewort, Corydalis hemidicentra, of the Qinghai-Tibet Plateau that by being camouflaged escapes herbivory from caterpillars of host-specialized Parnassius butterflies.

Machine learning-based feature selection and classification for cerebral infarction screening: an experimental study.

We investigate the application of machine learning techniques for feature selection and classification of speech and cognitive function assessments to enhance cerebral infarction screening. We analyze a dataset containing 117 patients (95 patients were diagnosed with cerebral infarction, and 54 were identified as lacunar cerebral infarction of them) comprising speech and cognitive function features from patients with lacunar and non-lacunar cerebral infarction, as well as healthy controls.

A novel frameshift variant leads to familial osteopetrosis with variable phenotypes in a Chinese Han consanguineous family.

Osteopetrosis, a group of highly heterogeneous genetic bone disorders, is characterized by deafness, increased bone density, hepatosplenomegaly, pancytopenia and intellectual disability. Osteopetrosis can be divided into three subtypes: autosomal recessive osteopetrosis (ARO), intermediate autosomal recessive osteopetrosis (IARO), and autosomal dominant osteopetrosis (ADO). CLCN7 has been reported to be the most common gene responsible for the ADO-II subtype.

Amygdalin alleviates LPS-induced acute lung injury in mice by targeting CD5L/iNOS pathway.

Amygdalins (AMY) from bitter almonds are distinguished by their anti-inflammatory, antibacterial and antioxidant properties, but their role in the treatment of acute lung injury (ALI) and their mechanisms need to be clarified. We sought to investigate whether AMY provides protection against lipopolysaccharide (LPS)-induced ALI in mice and explore the mechanisms of its protection. Results showed that AMY effectively alleviated LPS-induced ALI in a dose-dependent manner by reducing in vivo lung wet/dry ratio, lung/body weight ratio, and myeloperoxidase (MPO).

Multifunctionality of angiosperm floral bracts: a review.

Floral bracts (bracteoles, cataphylls) are leaf-like organs that subtend flowers or inflorescences but are of non-floral origin; they occur in a wide diversity of species, representing multiple independent origins, and exhibit great variation in form and function. Although much attention has been paid to bracts over the past 150 years, our understanding of their adaptive significance remains remarkably incomplete. This is because most studies of bract function and evolution focus on only one or a few selective factors.
