Adaptation to different environments can promote population divergence via natural selection even in the presence of gene flow-a phenomenon that typically occurs during ecological speciation. To elucidate how natural selection promotes and maintains population divergence during speciation, we investigated the population genetic structure, degree of gene flow and heterogeneous genomic divergence in three closely related Japanese phytophagous ladybird beetles: Henosepilachna pustulosa, H. niponica and H. yasutomii...

Herbal medicines have been used for the treatment of various ailments since time immemorial. Black cohosh (BC) is well known for the treatment of postmenopausal symptoms, with conflicting evidence supporting its safety and benefits. We present a rare case of BC-induced autoimmune hepatitis (AIH) with hepatotoxicity in a 69-year-old female. To our knowledge, this represents the third case of BC-induced AIH.

Due to the complexity and variation of the chemical constituents in authentic black cohosh (Actaea racemosa) and its potential adulterant species, an accurate and feasible method for black cohosh authentication is not easy. A high-resolution accurate mass (HRAM) LC-MS fingerprinting method combined with chemometric approach was employed to discover new marker compounds. Seven hydroxycinnamic acid amide (HCAA) glycosides are proposed as potential marker compounds for differentiation of black cohosh from related species, including two Asian species (A...

Previous studies indicate that the triterpene glycoside Actein from the herb black cohosh inhibits growth of human breast cancer cells. This study sought to investigate the effects of Actein on glioma cell growth and explore the potential mechanisms. Our results showed that administration of Actein significantly inhibited glioma cell viability in a dose- and time-dependent manner. Actein also increasingly inhibited the colony formation processes in glioma U87 cells and U251 cells. Administration of Actein also induced mitochondria-related apoptosis by increasing expression of pro-apoptotic factors Bax, cleaved caspase-3, cleaved caspase-9 and cleaved poly (ADP-ribose) polymerase 1 (PARP1) as well as decreasing anti-apoptotic Bcl-2 expression in U87 cells and U251 cells...

The results of large clinical trials have led physicians and patients to question the safety of hormone therapy for menopause. In the past, physicians prescribed hormone therapy to improve overall health and prevent cardiac disease, as well as for symptoms of menopause. Combined estrogen/progestogen therapy, but not estrogen alone, increases the risk of breast cancer when used for more than three to five years. Therefore, in women with a uterus, it is recommended that physicians prescribe combination therapy only to treat menopausal symptoms such as vasomotor symptoms (hot flashes) and vaginal atrophy, using the smallest effective dosage for the shortest possible duration...

Botanical dietary supplements are increasingly popular for women's health, particularly for older women. The specific botanicals women take vary as a function of age. Younger women will use botanicals for urinary tract infections, especially Vaccinium macrocarpon (cranberry), where there is evidence for efficacy. Botanical dietary supplements for premenstrual syndrome (PMS) are less commonly used, and rigorous clinical trials have not been done. Some examples include Vitex agnus-castus (chasteberry), Angelica sinensis (dong quai), Viburnum opulus/prunifolium (cramp bark and black haw), and Zingiber officinale (ginger)...

Investigating the phytochemical equivalence of the aerial parts of Actaea racemosa (syn. Cimicifuga racemosa) relative to the widely used roots/rhizomes, this study provides a perspective for the potential use of renewable ("green") plant parts as a source of black cohosh botanical preparations. In addition to the characterization of Nω-methylserotonin as one representative marker of the Actaea alkaloids, nine cycloartane triterpenes were isolated and characterized, including the two new triterpene glycosides (1S,15R)-1,15,25-trihydroxy-3-O-β-d-xylopyranosyl-acta-(16S,23R,24R)-16,23;16,24-binoxoside (1) and 3-O-α-l-arabinopyranosyl-(1S,24R)-1,24,25-trihydroxy-15-oxo-acta-(16R,23R)-16,23-monoxoside (2)...

Flow injection mass spectrometry and proton nuclear magnetic resonance spectrometry, two metabolic fingerprinting methods, and DNA sequencing were used to identify and authenticate Actaea species. Initially, samples of Actaea racemosa from a single source were distinguished from other Actaea species based on principal component analysis and soft independent modeling of class analogies of flow injection mass spectrometry and proton nuclear magnetic resonance spectrometry metabolic fingerprints. The chemometric results for flow injection mass spectrometry and proton nuclear magnetic resonance spectrometry agreed well and showed similar agreement throughout the study...

Black cohosh (Actaea racemosa) serves as the host plant for the Appalachian azure butterfly, Celastrina neglectamajor. Overharvesting of Black cohosh for the dietary supplement industry may result in its extirpation, and may also cause the elimination of the dependent butterfly. One way to increase or maintain the number of host plants in forested environments would be to reduce the number harvested, for example by increasing the levels of the desired metabolites in Black cohosh rhizomes. The secondary metabolites actein and deoxyactein are triterpene glycosides and are among the compounds associated with the putative activity of Black cohosh extracts...
