Therapeutic effect of forest bathing on human hypertension in the elderly.

Objective: To provide scientific evidence supporting the efficacy of forest bathing as a natural therapy for human hypertension.

Methods: Twenty-four elderly patients with essential hypertension were randomly divided into two groups of 12. One group was sent to a broad-leaved evergreen forest to experience a 7-day/7-night trip, and the other was sent to a city area in Hangzhou for control.

Effects of short-term forest bathing on human health in a broad-leaved evergreen forest in Zhejiang Province, China.

Objective: To investigate the effects of short-term forest bathing on human health.

Methods: Twenty healthy male university students participated as subjects and were randomly divided into two groups of 10. One group was sent on a two-night trip to a broad-leaved evergreen forest, and the other was sent to a city area.

Antiaging effect of pine pollen in human diploid fibroblasts and in a mouse model induced by D-galactose.

The present paper was designed to investigate the effect of pine pollen against aging in human diploid fibroblast 2BS cells and in an accelerated aging model, which was established by subcutaneous injections with D-galactose daily for 8 weeks in C57BL/6J mice. Pine pollen (1 mg/mL and 2 mg/mL) is proved to delay the replicative senescence of 2BS cells as evidenced by enhanced cell proliferation, decreased SA-β-Gal activity, and reversed expression of senescence-associated molecular markers, such as p53, p21(Waf1), p16(INK4a), PTEN, and p27(Kip1) in late PD cells. Besides, pine pollen reversed D-galactose-induced aging effects in neural activity and inflammatory cytokine levels, as indicated by improved memory latency time and reduced error rate in step-down test and decreased concentrations of IL-6 and TNF-α in model mice.

Cloning, characterization and tissue specific expression of Amur tiger (Panthera tigris altaica) IGF-I.

Insulin-like growth factor I (IGF-I) plays an important role in regulating gonad function, which is essential for normal reproduction in animals, especially in sexual receptivity and reproductive behavior. In this study, a cDNA encoding Amur tiger (Panthera tigris altaica) IGF-I was isolated from liver total RNA using RT-PCR. The IGF-I cDNA of Amur tiger (ATIGF-I) was highly homologous to that of other animals, 84.

Molecular cloning of giant panda pituitary prolactin cDNA and its expression in Escherichia coli.

cDNA encoding pituitary (PRL) of giant panda was obtained using RT-PCR and expressed in E. coli. The results revealed that panda PRL cDNA encodes a precursor protein of 229 amino acids including a putative signal peptide of 30 amino acids and a mature protein of 199 residues with one potential N-glycosylation site.

[Cloning and expression of pituitary prolactin gene in Ailuropoda melanoleuca].

The giant panda (Ailuropoda melanoleuca) is an endangered species and indigenous to China. It has been proposed that it has a highly specialized reproductive pattern with low fecundity, but little is known about its basic reproductive biology at molecular level. In this study,the pituitary prolactin (PRL) cDNA of giant panda was amplified by RT-PCR from pituitary total RNA and then cloned, sequenced and submitted to GenBank (GenBank accession No.
