background: one the main aspects of an in vitro fertilization (ivf) cycle is to avoid any possible systemic damage to women undergoing to a controlled ovarian hyperstimulation (coh). the aim of this work is to evaluate renal and hepatic function blood tests in patients undergoing controlled ovarian hyperstimulation during ivf cycles. materials and methods: all patients received a long stimulati...

Abstract Theta-burst stimulation (TBS) has been increasingly used to target prefrontal brain regions, such as the dorsolateral cortex (DLPFC), improve neurocognitive and emotional functioning. However, despite promising outcomes, there is still a lot of variability in responses clinical efficacy remains rather modest. Interestingly, fundamental research targeting motor suggested use priming tec...

Learning in neuronal networks can be investigated using dissociated cultures on multielectrode arrays supplied with appropriate closed-loop stimulation. It was shown in previous studies that weakly respondent neurons on the electrodes can be trained to increase their evoked spiking rate within a predefined time window after the stimulus. Such neurons can be associated with weak synaptic connect...

BACKGROUND Our aim was to study the effect of GnRH agonist and antagonist protocols of ovarian stimulation on oxidative stress parameters in serum and the influence of oxidative stress parameters change on the outcome of IVF cycles. METHODS This prospective study included 82 patients who underwent IVF procedures. We determined SOD, MDA and SH groups in serum. Serum samples were obtained betwe...

The type 1 and 8 adenylyl cyclase (ADCY1 ADCY8) exclusively account for Ca 2+ -stimulated cyclic AMP (cAMP) production regulate activity-dependent synaptic modification. In this study, we examined distinct forms of plasticity in the hippocampus Adcy1 −/− Adcy8 mice. We found that, at Schaffer collateral-CA1 synapses, while mice displayed normal long-term potentiation (LTP) following various ind...

The purpose of this investigation was to examine changes in sarcoplasmic reticulum (SR) function in muscles subjected to different patterns of muscle activity. Frog sartorius muscles were stimulated with tetanic trains (100 ms, 100 Hz) delivered at rates of 2.0, 0.5, and 0.2 trains/s. In one set of experiments, stimulation was continued until force had declined to ∼17% of initial (constant fati...

OBJECTIVE To compare two short protocols for ovarian stimulation in IVF cycles using an antagonist and an agonist short protocol. The outcomes studied were dosis rec FSH needed, days of stimulation, number of oocytes retrieved and pregnancy outcome. METHODS A prospective randomised study design. INCLUSION CRITERIA first or second IVF attempt in women younger than 40 years. In the agonist pr...

OBJECTIVE To compare the pregnancy outcomes achieved by in vitro fertilization (IVF) between minimal stimulation and conventional antagonist protocols in poor ovarian responders (PORs). MATERIALS AND METHODS In this randomized controlled trial, 77 PORs undergoing IVF were selected and divided into two groups. First group was the minimal stimulation group (n = 42) receiving 100 mg/day clomiphe...

OBJECTIVE To evaluate the effects of two stimulation waveforms on healing rates in patients with diabetes and open ulcers. The hypothesis was that stimulus waveforms with minimal polar characteristics would provide significant healing for this patient sample. RESEARCH DESIGN AND METHODS This was a prospective study that enrolled 80 patients with open ulcers. Patients received stimulation with...
