Different patterns of expression of the transcription factors of Nur77 and Nor-1 are induced following acute administration of typical and atypical antipsychotic drugs. The pharmacological profile of atypical antipsychotics suggests that serotonergic and/or adrenergic receptors might contribute to these reported differences. In order to test this possibility, we examined the abilities of seroto...

Parkinson adalah penyakit neurodegeneratif yang meningkat lebih cepat daripada gangguan neurologis lainnya. Saat ini pengobatan menggunakan dopamine agonist dan levodopa, namun memiliki efek samping seperti menurunkan nafsu makan tidak berfokus pada pencegahan kematian neuron. Salah satu protein berperan dalam patogenesis dari α-synuclein, di mana agregasi misfolding bersifat toksik neuron sehi...

BACKGROUND Takotsubo cardiomyopathy (TCM) is characterized by regional left ventricular dysfunction that cannot be explained by an occlusive lesion in a coronary artery. Catecholamines are implicated in the pathogenesis of TCM but the mechanisms involved are unknown. Because the endogenous and the most commonly used exogenous catecholamines have well defined adrenoceptor subtype affinities, inf...

Although most antidepressants suppress serotonin (5-HT) and/or noradrenaline reuptake, blockade of 5-HT(2C) receptors and α(2)-adrenoceptors likewise enhances monoaminergic transmission. These sites are targeted by the urea derivative N- [4-methoxy-3-(4-methylpiperazin-1-yl)phenyl]-1,2-dihydro-3-H-benzo[e]indole-3-carboxamide (S32212). S32212 was devoid of affinity for monoamine reuptake sites,...

In this study, to test the hypothesis that adrenergic vasoconstrictor responses of the legs are greater compared with the arms in human skin, cutaneous vascular conductance (CVC) in the forearm and calf were compared during the infusion of adrenergic agonists in healthy young volunteers. Under normothermic conditions, norepinephrine (NE, α- and β-agonist, 1 × 10(-8) to 1 × 10(-2) M), phenylephr...

G protein-coupled receptors (GPCRs) activate mitogen-activated protein kinases through a number of distinct pathways in cells. Increasing evidence has suggested that endosomal signaling has an important role in receptor signal transduction. Here we investigated the involvement of endocytosis in α(1A)-adrenergic receptor (α(1A)-AR)-induced activation of extracellular signal-regulated kinase 1/2 ...

background and purpose: the clinical outcome of intrauterine insemination (iui) treatment cycles employing a gonadotrophin-releasing hormone agonist [superfact)] or human chorionic gonadotrophin (hcg) for ovulation induction was compared. materials and methods: a group of 100 patients presenting with amenorrhoea, oligomenorrhoea or unexplained infertility were all treated with clomiphene 100 mg...

2-Phenylquinoline (1) degraded proteins under photo-irradiation with long-wavelength UV light without additives and under neutral conditions. We designed and synthesized a 2-phenylquinoline-estrogen receptor-α (ER-α) agonist (hybrid 2) and a 2-phenylquinoline-ER-α antagonist (hybrid 3) containing estradiol and 4-hydroxytamoxifen moieties, respectively. These 2-phenylquinoline hybrids effectivel...

The poor prognosis of esophageal squamous cell carcinoma (ESCC) emphasizes the urgent need to better understand the carcinogenesis and develop prevention strategies. Previous studies have highlighted the potential of using Vitamin E (tocopherols) for cancer chemoprevention, but the preventive activity of α-Tocopherol against ESCC remains to be elucidated. Our data showed that early-stage supple...
