Pseudostellaria heterophylla (Miq.) Pax is a mild tonic herb widely cultivated in the Southern part of China. The tuberous roots of P. heterophylla accumulate high levels of secondary metabolism products of medicinal value such as saponins, flavonoids, and isoquinoline alkaloids. Despite numerous studies on the pharmacological importance and purification of these compounds in P. heterophylla, their biosynthesis is not well understood. In the present study, we used Illumina HiSeq 4000 sequencing platform to sequence the RNA from flowers, leaves, stem, root cortex and xylem tissues of P...

Discharge of wastewater with high nitrogen and phosphorus content is a major cause of eutrophication. In this study, a microfiltration-based membrane photobioreactor (MPBR) and forward osmosis-based osmotic membrane photobioreactor (OMPBR) have been operated with Chlorella vulgaris for continuous tertiary wastewater treatment. Both the bioreactors exhibited good biomass accumulation (over 2g/L), although the OMPBR achieved better nutrients removal due to high rejection properties of the membranes. At 2days HRT, the OMPBR achieved nitrogen and phosphorus removal efficiencies of 86-99% and 100%, respectively, whereas the corresponding values in the MPBR were 48-97% and 46%, respectively...

Dry beans (Phaseolus vulgaris L.) are a nutrient dense food rich in protein and micronutrients. Despite their nutritional benefits, long cooking times limit the consumption of dry beans worldwide, especially in nations where fuelwood for cooking is often expensive or scarce. This study evaluated the nutritive value of 12 dry edible bean lines that vary for cooking time (20 to 89 min) from four market classes (yellow, cranberry, light red kidney, and red mottled) of economic importance in bean consuming regions of Africa and the Americas...

Effects of the developmental stage (e.g. young, mature or senescent) of leaves on their chemical composition have been described in literature. This study focuses on the variation in chemical composition and quantity and quality of proteins extracted from leaves due to variation in plant age (i.e. harvesting time), using leaves from sugar beets grown in field (Rhino, Arrival) and in greenhouse (Isabella). Within the same variety (Rhino-field, Arrival-field, Isabella-greenhouse) the protein content was similar for leaves from young and old plants (22±1, 16±1, and 10±3% w/w db, respectively)...

Purpose: The autoimmune blistering skin disease pemphigus vulgaris (PV) is caused by autoantibodies against desmosomal adhesion molecules. Patients may suffer conjunctival involvement, yet the underlying mechanisms are largely unclear. We characterized human and murine conjunctiva with respect to the PV autoantigens, and evaluated the effects and mechanisms of PV autoantibodies applied to human conjunctiva ex vivo. Methods: We obtained human conjunctiva specimens from surgical explants and established a short-term culture model to study the alterations induced by antibody fractions of PV patients (PV-IgG)...

Psoriasis is a T cell-mediated chronic inflammatory skin disease with inflammatory cell infiltrates in the dermis and epidermis. Previous studies suggested that there are some expanded T-cell receptor (TCR) clones in psoriatic skin. However, the effect of psoriasis on the immunological characteristics of TCR in circulating blood has not been reported. To address this, we performed high-throughput sequencing to reveal the immunological characteristics of TCR beta chain (TRB) in both psoriasis patients and healthy controls...

The standard management of acne vulgaris in Japan includes a combination of topical treatment with benzoyl peroxide (BPO) and BPO/clindamycin (CLDM), topical adapalene and systemic antimicrobials. However, the treatment of therapy-resistant complications such as postinflammatory hyperpigmentation (PIH), erosions with inflamed red papules and atrophic scars has not been established. We performed chemical peeling with glycolic acid and iontophoresis with ascorbyl 2-phosphate 6-palmitate and DL-α-tocopherol phosphate for the treatment of PIH, erosions with inflamed red papules and non-inflamed atrophic scars in 31 patients with acne vulgaris (mild to severe severity), and evaluated the efficacy and safety of these interventions...
