We continue our analysis of the general N-Higgs-doublet model and focus of the Higgs potential description in the space of gauge orbits. We develop a geometric technique that allows us to study the global minimum of the potential without explicitly finding its position. We discuss symmetry patterns of the NHDM potential, and illustrate the general discussion with various specific variants of the three-Higgs-doublet model. [less ▲]

The aim of this study was to assess the preventive effects of omega-3 polyunsaturated fatty acids (omega3 PUFA) and luteolin supplementation on allergen-induced inflammation in eight Ascaris suum (AS)-sensitised cats. Airway responsiveness (AR) tests were performed and venous blood and bronchoalveolar lavage fluid (BALF) collected before and following a single (AS-stimulated) allergen exposure, as well as at the end of a 4-week treatment period, which was followed by a second AS-challenge. The omega6/omega3 fatty acid ratio in erythrocyte membranes, BALF cytology, AR to carbachol, and BALF lipoxin A(4) (LXA(4)), an endogenous inhibitor of inflammation, were assessed at each time point. Compared to respective unstimulated values, AS-challenged cats exhibited a significant rise in BALF eosinophil percentage and there was a trend to increased BALF total cell counts, increased AR and reduced BALF LXA(4) concentrations. The significant decrease in the blood omega6/omega3 ratio seen after supplementation demonstrated that omega3 PUFA were efficiently absorbed. No changes in BALF cytology were found between untreated and treated AS-stimulated cats, but BALF LXA(4) levels were significantly elevated and AR significantly decreased following supplement intake. The study suggests that omega3-luteolin supplementation may have some beneficial effects on AR through a LXA(4)-dependent pathway in cats with experimentally-induced asthma. [less ▲]

OBJECTIVE: To investigate the influence of different pharmacological treatments on the intensity dependence of auditory evoked cortical potentials in migraineurs. BACKGROUND: Between attacks, patients with migraine show abnormalities in cortical information processing and decreased brain mitochondrial energy reserve. Both are most probably relevant for migraine pathogenesis, and they could be differentially modified by prophylactic drug therapy. Design.-The intensity dependence of the auditory evoked cortical potentials is, on average, increased in migraine. We have studied this intensity dependence in 26 patients before and after a 4-month period of prophylaxis with beta-blockers (n = 11, all migraine without aura; metoprolol or bisoprolol) or riboflavin (n = 15, migraine without aura: 13, migraine with aura: 2). Recordings were performed at least 3 days before or after an attack. RESULTS: After the treatment with beta-blockers, the intensity dependence of the auditory evoked cortical potentials was significantly decreased (before: 1.66+/-1.02 microV/10 dB; after: 0.79+/-1.06 microV/10 dB, P=.02). The decrease in intensity dependence was correlated significantly with clinical improvement (r = .69, P = .02). There was no change in intensity dependence after riboflavin treatment (before: 1.80+/-0.81 microV/10 dB; after: 1.56+/-0.83 microV/10 dB, P = .39), although the majority of patients showed improvement. CONCLUSIONS: These results confirm that beta-blockers and riboflavin act on two distinct pathophysiological mechanisms. Combining both treatments might enhance their efficacy without increasing central nervous system side effects. [less ▲]

One hundred and forty-five patients suffering from diseases requiring long-term treatment with high doses of corticosteroids (30 mg/day or greater of prednisolone) were recruited to the study. Patients had to be steroid naive on entry to the study (not more than 15 days of treatment with a corticosteroid within the previous 24 months). Patients were randomized to receive either 1 microgram/day alfacalcidol or placebo capsules for 12 months. Bone mineral density (BMD) of the lumbar spine was assessed by dual-photon absorptiometry on entry and after 3, 6 and 12 months' treatment. Safety was monitored by the recording of all adverse events reported by patients and the regular screening of blood samples for hematology and serum biochemistry. Of the 145 patients, 74 were randomized to alfacalcidol and 71 to placebo. The treatment groups were well matched at baseline with no significant differences in demographic, clinical or biochemical parameters. The mean equivalent dose of prednisolone at baseline was 46.6 mg/day and 46.3 mg/day for the alfacalcidol and placebo group respectively. From the 145 patients randomized to treatment, 71 (38 who received alfacalcidol and 33 who received placebo) provided BMD data both at baseline and at 3, 6 and 12 months. The percentage change in BMD after 6 months' treatment was -2.11% in the alfacalcidol group and -4.00% in the placebo group (p = 0.39). After 12 months the percentage change in BMD was +0.39% (CI: -4.28 to 4.81) in the alfacalcidol group and -5.67% (CI: -8.13 to -3.21) in the placebo group, this difference (6.06%, CI: 0.88 to 11.24) being statistically significant (p = 0.02). An intention to treat analysis also showed a significant difference between the two treatment groups in alfacalcidol's favor (3.81%, p = 0.01; CI: 0.92 to 6.70). There was no significant difference between the two treatment groups in the corticosteroid dose at any time point during the study. Serum calcium was measured throughout and there were no significant differences between the two treatment groups at any visit. This study suggests that alfacalcidol can prevent corticosteroid-induced bone loss from the lumbar spine. Long-term use of alfacalcidol was not associated with any significant adverse effects in this diverse group of patients. [less ▲]

STUDY OBJECTIVES: The electrophysiological correlates of anesthetic sedation remain poorly understood. We used high-density electroencephalography (hd-EEG) and source modeling to investigate the cortical processes underlying propofol anesthesia and compare them to sleep. DESIGN: 256-channel EEG recordings in humans during propofol anesthesia. SETTING: Hospital operating room. PATIENTS OR PARTICIPANTS: 8 healthy subjects (4 males) INTERVENTIONS: N/A MEASUREMENTS AND RESULTS: Initially, propofol induced increases in EEG power from 12-25 Hz. Loss of consciousness (LOC) was accompanied by the appearance of EEG slow waves that resembled the slow waves of NREM sleep. We compared slow waves in propofol to slow waves recorded during natural sleep and found that both populations of waves share similar cortical origins and preferentially propagate along the mesial components of the default network. However, propofol slow waves were spatially blurred compared to sleep slow waves and failed to effectively entrain spindle activity. Propofol also caused an increase in gamma (25-40 Hz) power that persisted throughout LOC. Source modeling analysis showed that this increase in gamma power originated from the anterior and posterior cingulate cortices. During LOC, we found increased gamma functional connectivity between these regions compared to the wakefulness. CONCLUSIONS: Propofol anesthesia is a sleep-like state and slow waves are associated with diminished consciousness even in the presence of high gamma activity.

The effect of propofol on the toxicity induced by glutamate (GLU), N-methyl-D-aspartate (NMDA), kainate (KA), and amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) was investigated on cultured fetal rat hippocampal neurons. The degree of neuronal injury was quantified by measuring the release of the neuron-specific enolase (NSE) into the culture media. The toxicity induced by brief exposure to GLU (10(-4) M) or to NMDA (10(-4) M) was significantly reduced by propofol, whereas that elicited by KA, AMPA (10(-4) M), or long GLU exposure was unaffected. In conclusion, high concentrations of propofol significantly attenuate NMDA receptor-mediated glutamate neurotoxicity in vitro. Further studies are needed to confirm this beneficial effect in vivo and to evaluate propofol as a neuroprotective anesthetic agent in pathologies involving glutamate release and NMDA-mediated toxicity.
