Z,Z-farnesol (Z,Z-FOH), the all- isomer of farnesol, holds enormous potential for application in cosmetics, daily chemicals, and pharmaceuticals. In this study, we aimed to metabolically engineer to produce Z,Z-FOH. First, we tested five Z,Z-farnesyl diphosphate (Z,Z-FPP) synthases that catalyze neryl diphosphate to form Z,Z-FPP in .

To investigate the clinical value of Mirena (levonorgestrel intrauterine sustained release system) combined with gonadotropin-releasing hormone agonist (GnRH-a) in patients with endometriosis, 80 patients with endometriosis (March 2019 ~ March 2020) were selected as the research object. According to the "random number table method", they were divided into the control group (treated with GnRH-a) and the observation group (treated with Mirena IUD combined with GnRH-a), with 40 cases included in each group. The total clinical efficacy, sex hormone level, carbohydrate antigen 125 (CA125) level, degree of pain and recurrence rate indexes were compared between the two groups.

This study aimed to investigate the effect of Tiaojingzhixue decoction on the expression of sex hormone and endometrial mRNA in perimenopausal patients with abnormal uterine bleeding. For this purpose, 84 patients with perimenopausal abnormal uterine bleeding who were treated in our hospital from January 2018 to January 2019 were divided into study group and control group, the control group was treated with mifepristone for six months, the clinical efficacy, time of symptom relief and disappearance, endometrial thickness, menstrual volume, adverse events, expression of sex hormone (ER), Progesterone receptor (PR), Lutropin (LH), Follicle-stimulating hormone (FSH), Estradiol (e2) and Vascular endothelial growth factor in endometrial tissue were compared between the two groups. The results showed that the clinical efficacy of the study group (97.

Dysfunctional uterine bleeding is menstrual bleeding in abnormal volume, duration, or time, and it is a common problem in women. A wide range of drug therapies, with varying efficacy, is available for women with dysfunctional uterine bleeding. The use of herbal and traditional medicine is one of the ways to treat this disease, which has fewer side effects than chemical drugs.

Light-absorbing and electrically conductive binary CNx nanocone (CNNC) arrays have been fabricated using a glow discharge plasma-assisted reaction deposition method. The intact CNNCs with amorphous structure and central nickel-filled pipelines could be vertically and neatly grown on nickel-covered substrates according to the catalyst-leading mode. The morphologies and composition of the as-grown CNNC arrays can be well controlled by regulating the methane/nitrogen mixture inlet ratio, and their optical absorption and resistivity strongly depend on their morphologies and composition.

CdS nanoneedles with different morphologies, structures, and growth modes have been grown on Ni-coated Si(100) surface under different experimental conditions by pulsed laser deposition method. The effects of catalyst layer, substrate temperature, and laser pulse energy on the growth of the CdS nanoneedles were studied in detail. It was confirmed that the formation of the molten catalyst spheres is the key to the nucleation of the CdS nanoneedles by observing the morphologies of the Ni catalyst thin films annealed at different substrate temperatures.
