A putative new emaravirus, named "ailanthus crinkle leaf-associated emaravirus" (ACrLaV), was detected in Ailanthus altissima with severe crinkle symptoms by RNA-Seq and RT-PCR. Four viral segments associated with ACrLaV were identified and fully sequenced, except for a few nucleotides at the genomic termini. The RNA-dependent RNA polymerase (RNA1), glycoprotein (RNA2), nucleocapsid protein (RNA3), and movement protein (RNA4), showed 26.

In 2019, a new disease characterized by yellow mottling on leaves was observed on Metaplexis japonica (Thunb.) Makino plants in Liaoning, China. Using RNA sequencing and PCR with overlapping primers, the complete nucleotide sequence of the circular double-stranded DNA genome of a new virus similar to caulimoviruses in diseased samples was determined.

Tomato spotted wilt virus (TSWV, Genus Orthotospovirus, Family Tospoviridae) is a thrips-transmitted negative-stranded RNA virus with a large host range. Major economic losses caused by TSWV have been recorded in various crops such as tomato, pepper and lettuce (Pappu et al., 2009; Adams et al.

In July 2018, a yellow mottle leaf disease was observed on the leaves of Euonymus bungeanus Maxim plants in Liaoning Province of China. Typical flexuous filaments (diameter, 13 nm; length, ca. 500 nm) were observed in extracts on the symptomatic leaves.

Objective: To investigate whether adipose-derived stem cells (ADSCs) induced by retinoic acid (RA) in vitro express primordial germ cell marker alkaline phosphatase (ALP) and vasa.

Methods: ADSCs were isolated from adult female SD rats and cultured in vitro. The third passage of ADSCs was identified by adipogenic differentiation, osteogenic differentiation and cell surface marker detection.

Objective: To observe the effect of transplantation of allogeneic adipose-derived stem cells (ADSCs) on serum biochemical indicators and sporting ability in highly endurance-trained rats from a fasciological perspective.

Methods: The ADSCs were cultured in vitro. Forty male Wistar rats were randomized into 4 equal groups, namely the blank control group, overtraining (model) group, transplantation without training group and overtraining plus transplantation group.

The aim of this study is to explore the correlations between fasciology and yin yang doctrine. Professor Yuan developed fasciology by three-dimensional reconstruction of connective tissue (fascia) in the trunk and limbs of the human body and tracing back to tissue origins in light of biological evolution and developmental biology. Fasciology states that the human body can be divided into two systems: the supporting-storing system and the functional system.

Objective: To investigate the effects of systemic transplantation of allogenic adipose-derived stem cells (ADSCs), the main undifferentiated cells in the supporting-storing system based on the fasciology hypothesis, on the bone mineral density (BMD) and histomorphometry in rats with glucocorticoid-induced osteoporosis (GIOP) rats, and explore a new therapeutic approach for osteoporosis.

Methods: Forty female adult Wistar rats were randomized equally into blank control group (A), model group (B), control treatment group (C) and treatment group (D). In groups B, C, and D, osteoporosis was induced by injection of prednisolone (8 mg/kg) via the tail vein 3 times a week for 12 consecutive weeks.
