Controllable microwave three-wave mixing via a single three-level superconducting quantum circuit.

Three-wave mixing in second-order nonlinear optical processes cannot occur in atomic systems due to the electric-dipole selection rules. In contrast, we demonstrate that second-order nonlinear processes can occur in a superconducting quantum circuit (i.e.

[Expression of inhibin B betaB subunits in the testicular tissues of azoospermia patients with different pathological alterations].

Objective: To investigate the expression of inhibin B betaB subunits in human testicular tissues.

Methods: Eighty-three cases of the azoospermia underwent testicular biopsy. In accordance with the pathological alterations of spermatogenesis, the samples were divided into four groups: Sertoli-cell-only syndrome (n = 21); hypospermatogenesis (n = 20), maturation arrest (n = 24) and almost normal spermatogenesis (n = 18).

[Effects of Fructus lycii and Radix astragali on the function of sertoli cells in rat testes].

Objective: To investigate the effects of the Chinese herbal medicines Fructus Lycii and Radix Astragali on the function of the Sertoli cells in the rat testis and their mechanisms.

Methods: Sertoli cells from the testes of the SD rats aged 18 - 22 days were isolated and cultured. The effects of Fructus Lycii, Radix Astragali and the combined administration of the two on the proliferation of Sertoli cells in vitro were detected by MTT assay, and their effects on the level of INHbetaB mRNA transcription in Sertoli cells in vitro were investigated in both normal environment and peroxide-damaging environment by RT-PCR.

[Relationship between pathological alterations of spermatogenic impairment and serum inhibin B concentration in patients with azoospermia].

Objective: To investigate the relationship between pathological alterations of spermatogenic impairment in seminiferous tubules and serum inhibin B concentration in patients with azoospermia and to verify the significance of INH B in evaluating spermatogenesis.

Methods: Eighty-three cases of azoospermia underwent testicular biopsy for the purpose of diagnosis. In accordance with the pathological alterations of spermatogenesis in seminiferous tubules, the samples were divided into four groups: Sertoli cell-only syndrome (n = 21); hypospermatogenesis (n = 20); maturation arrest (n = 24) and almost normal spermatogenesis (n = 18).

[Comparison of composite grafting of autoskin with acellular dermal matrix from different sources].

Objective: To compare the composite grafts of acellular dermal matrix (ADM) from different sources with autoskin.

Methods: Six local white mini pigs were employed for the experiment. The pigs were randomly divided into four groups according to different skin grafts, i.

[The establishment of testicular fibrosis model in Wistar rats].

Objectives: To establish the testicular fibrosis model in rats.

Methods: Wistar rats were divided into control group(n = 12) and model group(n = 40) randomly. Testicular fibrosis model was built with the classical method of establishing experimental autoimmune orchitis (EAO) combined with injecting Bacille Calmette-Guerin (BCG) into left testis.

Effect of mifepristone on estrogen and progesterone receptors in human endometrial and endometriotic cells in vitro.

Objective: To investigate the expressions of estrogen (E) receptor and progesterone (P) receptor in human eutopic and ectopic endometrium and the effect of mifepristone (RU486) on them.

Design: Prospective study.

Setting: University hospital.

[The activation of vagus afferent in response to lipopolysaccharide the role of interleukin-1].

To study the possibility of activation of vagus afferent in response to lipopolysaccharide (LPS) through interleukin-1 (IL-1), Wistar rats were randomly divided into LPS group and saline (NS) group. The expression of c-Fos, CD14 and Mac-1 were detected by immunohistochemistry staining. IL-1 bioactivity was determined by L929 cell proliferation.
