Current methods used in genome-wide association studies frequently lack power owing to their inability to detect heterogeneous associations and rare and multiallelic variants. To address these issues, quantile regression is integrated with a three (compressed) variance component multi-locus random-SNP-effect mixed linear model (3VmrMLM) to propose q3VmrMLM for detecting heterogeneous quantitative trait nucleotides (QTNs) and QTN-by-environment interactions (QEIs), and then design haplotype-based q3VmrMLM (q3VmrMLM-Hap) for identifying multiallelic haplotypes and rare variants. In Monte Carlo simulation studies, q3VmrMLM had higher power than 3VmrMLM, sequence kernel association test (SKAT), and integrated quantile rank test (iQRAT).

Traditional Chinese medicine can be used for Alzheimer's disease management, such as the modern herbal formula Di-Huang-Yi-Zhi (DHYZ). In the present study, neuronal differentiated PC12 cells were used as a model to evaluate the effects of DHYZ against amyloid-β peptide 25-35 (Aβ) induced neurotoxicity, particularly regarding cell proliferation, apoptosis and related events. Following treatment with DHYZ, cell viability, cell membrane damage, apoptosis, mitochondrial membrane potential, cytochrome c release, caspase-3 activity and levels of reactive oxygen species in PC12 cells were detected.

Sexual reproduction of heterothallic clavicipitaceous fungus Villosiclava virens (anamorph: Ustilaginoidea virens) generates ascospores, which is considered as primary infection source of rice false smut disease. However, little is known about the molecular underpinnings of sexual reproduction in V. virens.

Ascospores of Villosiclava virens are a primary infection source of rice false smut. This phytopathogenic fungus exists in heterothallic form, and mating compatibility is regulated by mating-type locus 1 (MAT1). However, the MAT1 locus structure remains unknown.

Rice false smut has become an increasingly serious disease in rice (Oryza sativa L.) production worldwide. The typical feature of this disease is that the fungal pathogen Ustilaginoidea virens (Uv) specifically infects rice flower and forms false smut ball, the ustiloxin-containing ball-like fungal colony, of which the size is usually several times larger than that of a mature rice seed.

Amyloid-beta induced neurotoxicity has been identified as a major cause of Alzheimer's disease. Acorus tatarinowii Schott is one of the most frequently used Chinese herbs for Alzheimer's disease treatment. However, the effects of Acorus tatarinowii Schott on amyloid-beta mediated nerve cell damage remains unknown.
