A randomized, multinational, noninferiority, phase III trial to evaluate the safety and efficacy of BF-200 aminolaevulinic acid gel vs. methyl aminol…
2018
Background: Basal cell carcinoma (BCC) represents the most common nonmelanoma skin cancer worldwide, affecting mainly adult, fair-skinned individuals. The World Health Organization distinguishes aggressive and nonaggressive forms, of which prototypical variants of the latter are primary nodular and superficial BCC. Objective: To demonstrate noninferiority of BF-200 ALA (a nanoemulsion gel containing 5-aminolaevulinic acid) compared with MAL (a cream containing methyl aminolaevulinate) in the treatment of nonaggressive BCC with photodynamic therapy (PDT). Noninferiority of the primary efficacy variable (overall patient complete response 12 weeks after last PDT) would be declared if the mean …
Effect of different treatments in calcium-free medium on basal tone and contractile responses of guinea pig tracheae.
1995
Acetylcholine (ACh; 0.1 mmol/l) and KCl (80 mmol/l) induce a biphasic contractile response in isolated guinea pig tracheae maintained at 37 degrees C either in the presence or absence of extracellular Ca2+. Exposure of the tissue to Ca(2+)-free solution evokes a significant decrease in basal tone and the sources of Ca2+ appear to be decreased by prolonged agonist stimulation, and even more by successive agonist stimulation. After an incubation period of 20 min in Ca(2+)-containing solution, the response is restored. Mg(2+)-depletion in Ca(2+)-free medium increased the contractile response to ACh, but not to KCl, and delayed the tonic component of the next contraction elicited in Ca(2+)-cont…
Variability in individual response to various doses of omeprazole. Implications for antiulcer therapy.
1994
This study was carried out in order to perform a combined prospective assessment of the individual pharmacodynamic response and of duodenal ulcer healing in patients treated with three different doses of omeprazole. Ninety-nine patients with endoscopically proven duodenal ulcers were subdivided into three parallel groups of 33 cases, who were randomly assigned to receive orally at 0800 hr, in single blind fashion, either 10 mg, 20 mg, or 40 mg of omeprazole. All of them underwent continuous intragastric pH monitoring both in basal conditions and on the fifth day of each dose regimen; ulcer healing was then assessed endoscopically after four weeks of treatment. All three doses of omeprazole …
Rotarod impairment: catalepsy-like screening test for antipsychotic side effects.
2009
Extrapyramidal motoric symptoms are casual side effects under antipsychotic medication. New generation antipsychotics are expected to have a reduced risk due to different receptor affinities. Here, haloperidol and the new generation antipsychotics, risperidone, amisulpride, and aripiprazole, were examined with both catalepsy test and rotarod performance test to screen for their usability in mice. Mice treated with haloperidol, risperidone, and aripiprazole showed dose and time-dependent impairment. Amisulpride-treated mice showed no signs of catalepsy. Catalepsy test and rotarod performance test were useful methods to detect side effects of both generation antipsychotics. Catalepsy test pro…
6-Hydroxydopamine lesioning differentially affects α-synuclein mRNA expression in the nucleus accumbens, striatum and substantia nigra of adult rats
2002
The effect of a unilateral 6-hydroxydopamine (6-OHDA) lesion and/or repeated administration of levodopa (L-DOPA) to normal and 6-OHDA-lesioned rats on alpha-synuclein mRNA expression was investigated by in situ hybridization histochemistry. A 6-OHDA lesion of the nigro-striatal pathway alone, confirmed by the loss of nigral tyrosine hydroxylase mRNA expression, markedly decreased alpha-synuclein mRNA in the lesioned substantia nigra (SN). In contrast, the levels of alpha-synuclein mRNA in the denervated striatum and nucleus accumbens were not altered. Chronic administration of L-DOPA to normal or 6-OHDA-lesioned rats had no effect on alpha-synuclein mRNA expression in the SN, striatum or nu…
Estradiol masculinizes the posteromedial cortical nucleus of the amygdala in the rat
2000
It has been demonstrated that the posteromedial cortical amygdaloid nucleus (PMCo), is sexually dimorphic. It is shown (Experiment 1) that male orchidectomy on the day of birth (D1) decreases the volume and number of neurons of the PMCo, while a single injection of propionate testosterone to the female on D1 masculinizes the PMCo in this gender. Since male gonadectomy on D1 (Experiment 2) is counteracted by a single injection of estradiol benzoate in males it has been suggested that the masculinization of the PMCo is due to the aromatization of testosterone to estradiol in this structure. These findings support the hypothesis that the development of sex differences in structures that belong…
Basal growth hormone concentrations in blood and the risk for prostate cancer: A case-control study
2005
OBJECTIVE To assess the relationship between basal serum growth hormone (GH) levels and prostate cancer risk. METHODS We conducted a population-based case-control study; cases included 68 men, aged 45–85 years, diagnosed with incident, primary, histologically confirmed, and clinically apparent (stage B and higher) prostate cancer. Controls included 240 men, frequency matched on age and residential area. Age, race, BMI, waist circumference, history of enlarged prostate, education, and current smoking status, were all considered as possible confounders. RESULTS We found a statistically significant trend of decreasing prostate cancer risk across increasing GH quintiles, in both crude (OR: 0.31…
Neuronal Correlates of Clinical Asymmetry in Progressive Supranuclear Palsy
2014
Progressive supranuclear palsy (PSP) is characterized by a symmetric hypokinetic syndrome with early falls and vertical supranuclear gaze palsy. However, clinically asymmetric manifestations occur, resembling idiopathic Parkinson disease or corticobasal degeneration. The aim of this study was to determine the neuronal correlates of patients suffering from PSP with a lateralized disease manifestation (hemi-PSP) in comparison to patients with symmetric clinical presentation (symPSP) and corticobasal degeneration.Twenty-three patients with PSP and 8 patients with corticobasal degeneration according to standard diagnostic criteria underwent F-fluorodeoxyglucose (FDG) PET scans to assess disease…
Basal Cerebral Computed Tomography as Diagnostic Tool to Improve Patient Selection in Asymptomatic Carotid Artery Stenosis
2012
One-hundred patients were included to evaluate the role of cerebral computed tomography (CT) to improve patient selection in asymptomatic internal carotid stenosis. Symptomatic patients were assigned to group A, asymptomatic patients to group B. A cerebral CT pattern A was observed in groups A and B in 60% and 20%, respectively ( P < .0001). Between A and B groups, type 6 plaques were found, respectively, in 26.7% and 7.5% of patients ( P = .01); a type 5 in 51.7% and 45% ( P = .32) of patients; and a type 4 in 21.7% and 47.5% of patients, respectively ( P = .006). Within B group, the association of CT pattern A and histological plaque level 4, 5, and 6 was, respectively, 25% ( P = .15)…
The effects of insulin on transport and metabolism of glucose in skeletal muscle from hyperthyroid and hypothyroid rats.
1997
The effects of insulin on the rates of glucose disposal were studied in soleus muscles isolated from hyper- or hypothyroid rats. Treatment with triiodothyronine for 5 or 10 days decreased the sensitivity of glycogen synthesis but increased the sensitivity of lactate formation to insulin. The sensitivity of 3-O methylglucose to insulin was increased only after 10 days of treatment and was accompanied by an increase in the sensitivity of 2-deoxyglucose phosphorylation; however, 2-deoxyglucose and glucose 6-phosphate in response to insulin remained unaltered. In hypothyroidism, insulin-stimulated rates of 3-O-methylglucose transport and 2-deoxyglucose phosphorylation were decreased; however, a…
