Objective: To determine the relationship between the cumulative effect of sequential clomiphene citrate (CC) treatments in unexplained infertile women with intercycle and intracycle serum hormone changes.
Materials And Methods: Patients who received CC 50 mg in the first cycle (group I, n=34) as ovulation induction and those who received CC 50 mg in the second consecutive cycle (group II, n=18) were compared. Basal (cycle days 2-5) and trigger day (the day that recombinant human chorionic gonadotropin is given) levels of gonadotropin and steroid hormones were measured.
Results: The 17OHP increase on trigger day was found to be statistically significantly higher in group II compared to the basal day (p=0.083). The testosterone (T) response on the trigger day of the patients in group II was found to be statistically significantly higher than that in group I (p=0.023). The number of selected follicles was negatively correlated with a follicle-stimulating hormone decrease and positively correlated with an estradiol increase. Endometrial thickness was positively correlated with a luteinizing hormone increase, and cycle cancelation was positively correlated with decreased estradiol.
Conclusion: Based on this study, it was concluded that the reason for the increased efficiency rate in successive cycles of CC may be the cumulative increase in T and 17OHP levels. However, this result was found not to affect the clinical pregnancy rate.

Spatially and temporally controlled drug delivery is an important field to address the limitations of conventional pharmaceutical administration. While many effective controlled drug delivery systems exist, the repertoire of systems that additionally present a beneficial mechanical environment to cells remains scarce. To address this, a comprehensive release study of fluorescein as a model drug, and the corticosteroid dexamethasone, from poly(-isopropylacrylamide)/polypyrrole (pNIPAM/PPy) conducting polymer hydrogels is presented within this study.

Generalized bullous fixed drug eruption (GBFDE) is a severe form of FDE characterized by vesicles or bullae and involvement of a significant portion of the body surface area. To date, no association between GBFDE and chlordiazepoxide has been reported in the literature.

Early-life experiences shape neural networks, with heightened plasticity during the so-called "sensitive periods" (SP). SP are regulated by the maturation of GABAergic parvalbumin-positive (PV+) interneurons, which become enwrapped by perineuronal nets (PNNs) over time, modulating SP closure. Additionally, the opening and closing of SP are orchestrated by two distinct gene clusters known as "trigger" and "brake".

Background And Objectives: COVID Stress Syndrome (CSS) is a new type of health anxiety triggered by the COVID epidemic. However, we know little about the causal relationship with CSS symptoms and the temporal and dynamic interactions between symptoms and cognitive processes associated with health anxiety.
Design: During the epidemic of COVID-19, 193 Chinese university students completed experience sampling methods on CSS symptoms and related constructs of health anxiety three times a day for 14 days.
