Exploring the physiological response differences of β-caryophyllene, linalool and citral inhalation and their anxiolytic potential.

Essential oils with β-caryophyllene, citral, and linalool as key compounds often exhibit some anti-anxiety like effects in aromatherapy. However, evidence of the effect of these three compounds through human inhalation remains limited. It is worth exploring their potential anxiolytic effect through the olfactory pathway, and finding out whether the three compounds lead to different physiological responses.

A feasibility study on indoor therapeutic horticulture to alleviate sleep and anxiety problems: The impact of plants and activity choice on its therapeutic effect.

Introduction: Therapeutic horticulture (TH) is increasingly being applied for sub-health or patient mental health care. Whether plant and activity type will affect TH's effectiveness is unclear.

Aim: To evaluate the feasibility of an indoor TH for alleviating the anxiety symptoms and sleeping problems of people with poor sleep quality, and explore the potential affection of plant and activity type on health benefits.

Isolation and identification of active ingredients and biological activity of Dioscorea nipponica Makino.

This study reported the isolation and identification of bioactive compounds from Dioscorea nipponica Makino, a plant used in traditional medicine for various ailments. Nine compounds were isolated, including a new compound named as diosniposide E, which was elucidated by analyzing its H-NMR, C-NMR, DEPT, COSY, HMBC and MS data and comparing them with data available in literature. The other eight compounds were identified as known compounds.

Odor perception of aromatherapy essential oils with different chemical types: Influence of gender and two cultural characteristics.

Olfactory perception, and especially affective responses of odors, is highly flexible, but some mechanisms involved in this flexibility remain to be elucidated. This study investigated the odor perceptions of several essential oils used in aromatherapy with emotion regulation functions among college students. The influences of people's characteristics including gender, hometown region, and fragrance usage habit on odor perception were further discussed.

Gold nanorods contained polyvinyl alcohol/chitosan nanofiber matrix for cell imaging and drug delivery.

Gold nanorods (AuNRs) that contained polyvinyl alcohol/chitosan (PVA/CS) hybrid nanofibers with dual functions are successfully fabricated by a simple electrospinning method. The results of transmission electron microscopy (TEM), X-ray diffraction (XRD) and energy dispersive X-ray (EDX) spectroscopy indicate that AuNRs are indeed encapsulated into the PVA/CS hybrid nanofibers. FTIR spectra results demonstrate that the chemical structures of PVA and CS are not affected when the AuNRs are introduced into the fibers.

Biocompatible core-shell electrospun nanofibers as potential application for chemotherapy against ovary cancer.

Polyvinyl alcohol/chitosan (PVA/CS) core-shell nanofibers are successfully fabricated by a simple coaxial electrospinning method, in which PVA forms the core layer and CS forms the shell layer. With the change of the feed ratio between PVA and CS, the surface morphology and the microstructures of the nanofibers are largely changed. The as-prepared core-shell fibers can be used as a carrier for doxorubicin (DOX) delivery.

Screening and monitoring zearalenone-producing Fusarium species by PCR and zearalenone by monoclonal antibodies in feed from China.

Screening of zearalenone (ZEN)-producing species and monitoring of ZEN in feed were performed by using anti-zearalenone monoclonal antibodies. ELISA recoveries of ZEN from corn distillers dried grains with solubles (DDGS) feed, corn feed, rice bran, soybean meal, wheat bran and rapeseed dregs were between 78.6% and 88.

[Using HTS-ELISA method to make anti-aflatoxin M1 monoclonal antibody].

Objective: To prepare high-affinity anti-aflatoxin M1 monoclonal antibodies by High Throughput Screening ELISA (HTS-ELISA) METHODS: Balb/C mice were immunized by aflatoxin M1-bovine serum albumin conjugate, and screen secret anti-aflatoxin M1 monoclonal antibody hybridoma by HTS-ELISA. The antibody was characterized.

Results: Fourteen hybridoma cell lines which could secret high activity anti-aflatoxin M1 monoclonal antibodies were obtained.
