Abstract
BACKGROUND AND PURPOSE The presence of a continuum between physiological déjà vu (DV) and epileptic DV is still not known as well as epidemiological data in the Italian population. The aim was to identify the epidemiological distribution of DV in Italy, and secondly to look for specific features of DV able to discriminate between epileptic and non-epileptic DV. METHODS In all, 1000 individuals, 543 healthy controls (C) (313 women; age 40 ± 15 years) and 457 patients with epilepsy (E) (260 women; age 39 ± 14 years), were prospectively recruited from 10 outpatient neurological clinics throughout Italy. All populations were screened using the Italian Inventory for Déjà Vu Experiences Assessment (I-IDEA) test and E and pairwise C underwent a comprehensive epilepsy interview. RESULTS Of E, 69% stated that they experienced 'recognition' and 13.2% reported that this feeling occurred from a few times a month to at least weekly (versus 7.7% of the control group). Furthermore, a greater percentage of E (6.8% vs. 2.2%) reported that from a few times a month to at least weekly they felt that it seemed as though everything around was not real. In E, the feeling of recognition raised fright (22.3% vs. 13.2%) and a sense of oppression (19.4% vs. 9.4%). A fifth of E felt recognition during epileptic seizures. CONCLUSION Only E regardless of aetiology firmly answered that they had the feeling of recognition during an epileptic seizure; thus question 14 of the I-IDEA test part 2 discriminated E from C. Paranormal activity, remembering dreams and travel frequency were mostly correlated to DV in E suggesting that the visual-memory network might be involved in epileptic DV.

Abstract
BACKGROUND AND PURPOSE Misdiagnosis of refractory epilepsy (rE) is common and such patients experience a long diagnostic delay. Our aim was to identify key clinical/laboratory factors in order to obtain an alternative diagnosis in patients referred for rE. METHODS Between January 2010 and December 2015, 125 consecutive patients with a diagnosis of rE were prospectively enrolled. All patients underwent a comprehensive neurological, neuropsychiatric and cardiological evaluation, and had an observation time of at least 1 year after the study entry. RESULTS Diagnosis of rE was confirmed in 104/125 (83.2%) patients (55 women, mean age 38.8 ± 14.3 years). Thirteen/125 patients (10.4%, seven women, mean age 50.8 ± 20.9) were diagnosed with syncope, which was cardiac/cardio inhibitory in 9/13 (69%). The remaining 8/125 patients (6.4%, six women, mean age 41.2 ± 14.6 years) were diagnosed with psychogenic non-epileptic seizures. Age at onset had a high accuracy in differentiating patients with syncope from others, with the best cut-off age at 35 years and above. Abnormal brain magnetic resonance imaging (MRI) had a significant yield of about 70% in rE. A diagnostic model including age at onset and brain MRI was highly accurate in differentiating patients with syncope from others. In patients with cardiac/cardio inhibitory syncope, the point score of historical features was ≥1 and falsely favoured the diagnosis of epileptic seizures. CONCLUSIONS This prospective cohort study identifies rE mimics who are at high risk of morbidity and mortality. rE starting in adulthood should raise a high suspicion of cardiac syncope. Brain MRI is accurate in differentiating rE from other conditions.

Abstract
BACKGROUND AND PURPOSE To evaluate if an automatic magnetic resonance imaging (MRI) processing system may improve detection of hippocampal sclerosis (Hs) in patients with mesial temporal lobe epilepsy (MTLE). METHODS Eighty consecutive patients with a diagnosis of MTLE and 20 age- and sex-matched controls were prospectively recruited and included in our study. The entire group had 3-T MRI visual assessment of Hs analysed by two blinded imaging epilepsy experts. Logistic regression was used to evaluate the performances of neuroradiologists and multimodal analysis. RESULTS The multimodal automated tool gave no evidence of Hs in all 20 controls and classified the 80 MTLE patients as follows: normal MRI (54/80), left Hs (14/80), right Hs (11/80) and bilateral Hs (1/80). Of note, this multimodal automated tool was always concordant with the side of MTLE, as determined by a comprehensive electroclinical evaluation. In comparison with standard visual assessment, the multimodal automated tool resolved five ambiguous cases, being able to lateralize Hs in four patients and detecting one case of bilateral Hs. Moreover, comparing the performances of the three logistic regression models, the multimodal approach overcame performances obtained with a single image modality for both the hemispheres, reaching a global accuracy value of 0.97 for the right and 0.98 for the left hemisphere. CONCLUSIONS Multimodal quantitative automated MRI is a reliable and useful tool to depict and lateralize Hs in patients with MTLE, and may help to lateralize the side of MTLE especially in subtle and uncertain cases.

Abstract
According to the ToGA trial, HER2 has been shown to be predictive for the success of treatment with trastuzumab in advanced gastric cancer (AGC). A number of studies have analyzed HER-2/neu overexpression in gastric carcinoma and identified the rate of HER2 positivity to be markedly varied. To date, the prevalence of HER2 overexpression in Sicilian people with AGC is unknown. Therefore, in the present study, a retrospective immunohistochemical analysis of HER2 was performed in a cohort of 304 AGC samples that were obtained from the archives of 10 Sicilian anatomopathological diagnostic units in order to verify the positive rate of HER2-positive cases. Furthermore, the characteristics of histotype, grade, stage and Ki-67 expression were also analyzed. HER2 overexpression was encountered in 17.43% of all the gastric adenocarcinomas, which was consistent with the results that have been reported elsewhere in the literature. A progressive increase in HER2 overexpression was observed, from the poorly cohesive histotype to the tubular adenocarcinomas and gastric hepatoid adenocarcinomas. HER2 overexpression was significantly associated with a high grade, advanced stage and high Ki-67 labeling index. Further investigations performed jointly by pathologists and oncologists within the geographical area of the present study should confirm that the association of trastuzumab with chemotherapy results in an improvement of survival in patients with AGC.

Abstract
We have already shown that brain MR imaging of healthy individuals frequently reveals either unilateral or bilateral Hh, which is considered a hallmark of hippocampal sclerosis. We performed a follow-up (5-year interval) clinical and advanced imaging study of these individuals to address whether Hh may have masked occult brain atrophy or contributed to a later onset of epilepsy. Subjects with Hh (n = 13) underwent a detailed clinical-imaging protocol, with a 3T scan and were studied with automated hippocampal segmentation (FreeSurfer), whole brain voxel-based morphometry, and shape analysis. All 13 subjects with Hh had normal neurologic examination findings with no cognitive impairment. Multimodal structural neuroimaging methods did not show clear evidence of significant volumetric changes between subjects with or without Hh. We clearly showed that Hh is not associated with any occult brain atrophy; furthermore, none of the healthy subjects with MR imaging evidence of Hh developed epilepsy or trouble with cognition.

Abstract
BACKGROUND AND PURPOSE Autosomal dominant nocturnal frontal lobe epilepsy (ADNFLE) is a distinct epileptic syndrome with a broad range of severity even amongst affected members of the same pedigree, and the level of pharmacoresistance may reach 30%, close to that seen in sporadic focal epilepsies. METHODS To investigate this issue of phenotypic heterogeneity, we prospectively carried out a high-resolution 3-T magnetic resonance imaging (MRI) study in an ADNFLE family containing 10 affected members including one pharmacoresistant patient and carrying the V287L mutation of the CHRN beta2 subunit (CHRNB2). MRI studies were evaluated in a manner blinded to the electro-clinical data. RESULTS The brain MRI showed normal results in all affected individuals except the 22-year-old right-handed woman (member III-7) who had refractory seizures and typical radiological signs of left hippocampal sclerosis. She also had a simple febrile seizure at the age of 10 months. CONCLUSION The results of this study illustrate that hippocampal sclerosis has offered a fertile substrate for intractable ADNFLE to develop. The present findings also highlight the importance of acquired factors that are directly relevant to the epilepsy phenotype and its severity even in monogenic epilepsies.

Abstract
BACKGROUND AND PURPOSE Rectal biopsy is usually performed for in vivo diagnosis of Kufs disease (KD). We evaluated the usefulness of rectal biopsy in the diagnosis of such condition by comparing ultrastructural data of patients with suspicion of KD with those of control subjects. Furthermore, we reviewed literature data concerning the value of such a diagnostic procedure in the diagnosis of KD. METHODS Sixty-five subjects were enrolled and underwent rectal biopsy. Of these, 13 had a clinical picture in keeping with KD, whereas 52, affected by Irritable Bowel Syndrome, constituted the control group. RESULTS Ultrastructural analysis evidenced fingerprint (FP) inclusions in 12 subjects, 4/13 with suspicion of KD and 8/52 controls. In patients, FPs were mainly located in vascular smooth muscle cells (VSMC) while in controls they were mostly found in pericytes and VSMC. No FPs were found in one patient with genetically confirmed KD. In literature, we identified 14 KD patients who underwent rectal biopsy. In most reports, ultrastructural features were not systematically analyzed or described. CONCLUSIONS Fingerprints are the most common ultrastructural finding in rectal biopsy in patients with suspicion of KD. However, their presence in pericytes and VSMC is not specific for KD because they may be found in controls subjects. Our literature review revealed that data on the value of rectal biopsy in the diagnosis of KD are scarce. In light of these findings, the relevance of rectal biopsy in such condition should be re-evaluated.

Abstract
BACKGROUND Idiopathic peripheral facial nerve palsy or Bell's palsy (BP) is the most common cause of facial nerve palsy. OBJECTIVE To evaluate the role of glucose metabolism abnormalities in BP. METHODS We identified 148 patients with unilateral BP and 128 control subjects. In all we evaluated glucose level at fasting and after a 2-h oral glucose tolerance test (2h-OGTT). In addition we determined insulin resistance (IR), by HOMA-index. Patients and controls were divided in to two groups, according to their Body Mass Index (BMI). RESULTS Following a 2h-OGTT, the prevalence of glucose metabolism abnormalities was significantly higher in patients with BP than in controls (P < 0.001). Impaired glucose tolerance (IGT) was found in 57 (38%) patients and in 23 (18%) controls, while a new-diagnosed DM (NDDM) was found in 29 (19%) patients and in 8 (6%) controls. The IR was significantly increased only in BP patients with BMI ≥ 24.9 (P = 0.005). BMI, waist circumference, blood pressure, tryglicerides, serum lipid, drugs use were not significantly different between patients and controls. CONCLUSIONS In this study we found that prediabetes is frequently associated with facial palsy. We propose to perform a 2h-OGTT in patients with peripheral facial palsy and normal fasting glycaemia. HOMA-index should be evaluated in obese facial palsy patients.

Abstract
BACKGROUND Various nuclear envelope derivatives, such as the annulate lamellae, the intranuclear tubules as well as the nuclear projections and pockets may be observed electron microscopically in tumour cells. PATIENTS AND METHODS In a series of eight gastric adenocarcinomas, ultrastructural features of nuclear envelope changes were analyzed and correlated to the biology of the tumours. RESULTS Histologically, three tumours were intestinal-type adenocarcinomas and showed annulate lamellae in the cytoplasm of some tumor cells. Five tumors were mixed-type adenocarcinomas, with a solid growth pattern; two of these tumours were characterized by the presence of intranuclear tubules, whereas the remaining three tumours exhibited nuclear pockets and projections. Seven out of eight patients died due to metastatic disease during the follow-up period (median 31 months). CONCLUSION Ultrastructural evaluation of pleomorphism of the nuclear envelope may be an ancillary method for the pathologist in the study of nuclear grading of gastric carcinomas.

Abstract
Objectives The aim of this study was to correlate the brain atrophy with serum levels of anti-GM1 antibodies in patients with relapsing–remitting multiple sclerosis (RRMS). Methods Plasma sample from 52 patients with RRMS and 65 healthy controls were examined for anti-GM1 antibodies. Patients with RRMS underwent to MRI study with automated method called SIENAX that calculated an estimate of gray matter (GMV) and white matter (WMV) volumes. Results The percentage of RRMS patients with increased anti-GM1 was 37.8%. Elevated levels of anti-GM1 antibodies did not correlate with brain atrophy. Conclusions Anti-GM1 antibodies do not represent a marker of axonal damage in patients with RRMS.

Abstract
OBJECTIVE To determine whether there is MRI-detectable mesial temporal sclerosis (MTS) in patients with sporadic benign temporal lobe epilepsy (BTLE). METHODS Brain MRIs were obtained from 101 consecutive, unrelated patients (51 women; mean age 37.3 +/- 17.5 years; range 10 to 83 years) with BTLE, who reported rarely or never having had seizures at the time of long-term (> 2 years) follow-up. The mean age at seizure onset was 22.3 +/- 17.4 years; the mean duration of epilepsy was 16.4 +/- 14.1 years. MRI diagnosis of MTS was based on the occurrence of hippocampal formation atrophy on T1 slices, an increased mesial temporal signal intensity alteration on fluid-attenuated inversion-recovery (FLAIR) or T2 images, or both. RESULTS Thirty-nine of 101 patients (38.6%) had MRI evidence of unilateral MTS (19/39 left MTS, 20/39 right MTS), which correlated with the epileptiform activity. Hyperintense FLAIR and T2 signal with or without atrophy was observed in 24 of 39 individuals. There was no difference between patients with or without MRI-detected MTS in age at onset and duration of epilepsy. Family history of epilepsy or febrile convulsions (FCs) was more frequent in patients with MRI-detected MTS (36%) as compared with patients with normal MRI (22.7%), but the difference was not significant. Antecedent FCs were more frequent (p = 0.03) in patients with MRI-detected MTS (9/39; 23%) vs those with normal MRI (5/62; 8%). CONCLUSIONS MRI-detected mesial temporal sclerosis is often encountered in patients with sporadic benign temporal lobe epilepsy.

Abstract
Functional MRI with simultaneously acquired EEG (fMRI/EEG) can identify areas of signal change associated with interictal discharges. We report the fMRI/EEG study of a child with newly-diagnosed IGE, performed prior to the start of antiepileptic medication. The 7-years-old girl had very frequent absences, associated with eyelid myoclonia. Her EEG showed frequent, typical 3/sec discharges. Functional MRI was performed with a 3T scanner using whole brain gradient echo-planar imaging, and the EEG was recorded with 18, non-metallic, scalp electrodes. Ten bursts of generalized discharges were captured during 30 minutes fMRI/EEG acquisition. The bursts lasted 3.4 (SD +/- 0.6) seconds. Event-related analysis was performed with SPM2 and iBrain software. Functional MRI showed prominent, bilateral thalamic activation, and less pronounced areas of cortical activation and deactivation. This study demonstrates thalamic activation in typical, untreated childhood absence epilepsy. The cortical signal change may be related to a thalamo-cortical circuit.

Abstract
OBJECTIVE To investigate the possible occurrence of a conversion event in three patients with adult-onset spinal muscular atrophy (SMA) type IV, which represents the mildest form within the spectrum of the SMA phenotype. MATERIAL AND METHODS We observed three patients with adult onset SMA and apparent isolated deletion of telomeric survival motor neuron (SMN1) exon 7. To distinguish between a deletion and a sequence conversion event of exon 7, these patients were analyzed in greater detail by a simple PCR-based assay. RESULTS Analysis by DdeI digestion showed products for both telomeric and centromeric copies of exon 8. These findings indicated a gene conversion event as the site for primer R111 was retained at least in one of two alleles. CONCLUSIONS These results provide first evidence that a conversion event may be also associated with adult-onset SMA, and further support the notion that a gene conversion event is usually associated with a milder SMA phenotype and a later onset of disease.

Abstract
OBJECTIVE To determine whether methylene tetrahydrofolate reductase (MTHFR) C677T mutation, factor II G20210A mutation and factor V Leiden are risk factors for retinal vein occlusion (RVO) in patients under fifty years of age. METHODS Comparison of 29 patients, under 50 years old of age, as affected RVO and 62 age matched normal controls. Plasma MTHFR C677T genotype, Factor II G20210A genotype, Factor V Leiden genotype, S protein level, C protein level, APCR presence (Actived Protein C Resistance), homocysteine level and Beta-thromboglobulin level were determined. RESULTS Seventeen RVO patients and twenty-one controls were heterozygous for the MTHFR C677T mutation. Three RVO patients and twenty-three controls were homozygous for the MTHFR C677T mutation. Three RVO patients and two controls were heterozygous for the factor II G20210A mutation. One control was heterozygous for the factor V Leiden. CONCLUSIONS This study fails to demonstrate that these mutations are risk factors for RVO in patients under fifty years of age.

Abstract
BACKGROUND Dysfunction of gamma-aminobutyric acid (GABA) (B) receptors has been implicated in the pathogenesis of temporal lobe epilepsy (TLE). OBJECTIVE To evaluate the genetic contribution of cloned human GABA(B) receptors to TLE. METHODS The authors genotyped 141 patients (78 women and 63 men; mean age = 49.1 +/- 18.0 years) with nonlesional TLE and 372 age- and sex-matched normal individuals for the known polymorphism G1465A in the human GABA(B) receptor 1 [GABA(B[1])] gene. RESULTS There was a highly significant overrepresentation of the G1465A heterozygote in patients with TLE compared with controls. The A/G genotype was found in 17% of the 141 patients with TLE and in only 0.5% of the 372 controls (p < 0.0001). The authors also found that patients carrying the A allele had a significantly higher risk (p = 0.003, OR = 6.47, 95% CI = 2.02 to 20.76) of developing drug-resistant TLE. Furthermore, the age at onset of seizures tended to be lower in patients with A/G genotype, but the difference was not significant. CONCLUSIONS The results of this study indicate that the GABA(B[1]) polymorphism (G1465A) confers a highly increased susceptibility to TLE. Moreover, it seems to influence the severity of this common epileptic disorder.

Abstract
PURPOSE To delineate the electroclinical features of patients with partial seizures in adolescence with a benign outcome. METHODS Patients were recruited in five different Italian epilepsy centers. Patients were selected among those with partial seizures between ages 11 and 17 years. We excluded benign childhood epilepsies, those with neurologic or mental deficits, and those with neuroradiologically documented lesions. We also excluded patients with less than 3 years' follow-up or who were still receiving antiepileptic therapy. RESULTS There were 37 (22 male, 15 female) patients. Seizures started at the mean age of 14.5 years (range, 11-16.11). Two main electroclinical patterns emerged: 16 of 37 patients had somatomotor seizures frequently associated with focal theta discharges involving the centroparietal regions. Ten of 37 patients showed versive seizures and interictal spiking involving the posterior regions. A third group had clinical characteristics resembling the cases described by Loiseau. All had a favorable outcome. CONCLUSIONS This relevant multicenter study further confirms the existence of benign partial epilepsies with onset during adolescence.

Abstract
PURPOSE To evaluate how many patients with a clinical picture of idiopathic childhood localization-related epilepsies may also have silent celiac disease (CD). This will help determine whether investigation for CD should be restricted to those patients with childhood partial epilepsy with occipital paroxysms (CPEO) or should be extended to all patients with childhood partial epilepsy (CPE) regardless of seizure type and electroencephalographic (EEG) paroxysms. METHODS The study group consisted of 72 patients (31 girls and 41 boys; mean age, 12.6 +/- 4.28 years; age at onset, 6.4 +/- 3.7 years) who were observed consecutively over a 5-year period and who received an initial diagnosis of idiopathic CPE. A diagnosis of CD was confirmed by using enzyme-linked immunosorbent assay (ELISA) to assess the presence of antigliadin antibodies and the immunofluorescent undirected test to assess the presence of antiendomysium antibodies. RESULTS Twenty-five patients had CPEO, whereas the remaining 47 had CPE with centrotemporal spikes (CPEC). None of the patients with CPEC had positive antibody tests. Of the 25 patients with CPEO, two (8%) had antiendomysium immunoglobulin (Ig) A antibodies. In both of these patients, the jejunal biopsy showed atrophy of the villi and hyperplasia of the crypts, consistent with a diagnosis of CD. Brain computed tomography (CT) was normal in one of these patients and revealed occipital corticosubcortical calcifications in the other. CONCLUSIONS Our study indicates that CD screening should be performed routinely only in patients with CPEO.

Abstract
BACKGROUND Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary syndrome caused by mutations of the Notch3 gene, usually localized to exons 3 and 4. OBJECTIVES To report a novel pathogenetic mutation occurring in exon 6 of the Notch3 gene, a location not previously recognized in patients with CADASIL, and to report the results of magnetic resonance spectroscopy in CADASIL. METHODS Mutation analysis of the Notch3 gene was performed in 2 patients belonging to a large kindred manifesting CADASIL, as well as in 7 clinically unaffected members of the family and 200 control chromosomes. Proton magnetic resonance spectroscopy was used to estimate metabolite resonance intensities in the 2 affected subjects. RESULTS Sequence analysis of the Notch3 gene showed a new missense mutation CGC-->TGC in codon 332 of exon 6, resulting in the replacement of an arginine residue with a cysteine. This mutation was never observed in the 7 unaffected members of the family and the 200 control chromosomes examined. Proton magnetic resonance spectroscopy showed a diffuse decrease in cerebral N-acetylaspartate, indicating the presence of widespread axonal damage. CONCLUSIONS Our findings emphasize the role of direct DNA sequence analysis for the diagnosis of CADASIL. Moreover, the results of proton magnetic resonance spectroscopy suggest that widespread axonal damage may be an early finding of the disease.

Abstract
A 9-year-old girl, who had no family history of neurologic diseases in the first-degree relatives, had a 3-year history of progressive myoclonus epilepsy (PME). A thorough laboratory investigation was normal. As two sisters of her paternal grandmother were said to have Huntington's disease (HD), the authors looked for HD and found a CAG repeat expansion of 115 repeats. This diagnosis should be considered in addition to other causes in patients with PME. Moreover, the current case further supports the notion that HD should be considered even when a family history is not obvious.

Abstract
Mutations in the parkin gene have been reported in patients with early onset PD. The authors investigated the parkin gene in 118 patients who had an onset of PD after age 45 years: 95 subjects were sporadic patients and 23 subjects were from 18 families with a probable autosomal recessive inheritance. No pathogenetic mutations in the parkin gene were detected either in familial or in sporadic patients. Moreover, no differences were found between patients and 100 age-matched normal controls in the allele and genotype frequencies of four exonic parkin polymorphisms.

Abstract
BACKGROUND There is evidence that patients with chronic daily headache (CDH) may have isolated intracranial hypertension without papilledema (IHWOP). Recent studies have emphasized that isolated IH may be due to cerebral venous thrombosis (CVT). OBJECTIVE To detect the occurrence of CVT in patients with CDH. METHODS The authors investigated the occurrence of CVT in 114 consecutive patients with CDH by using MR venography (MRV). A portion of these patients underwent a lumbar puncture (LP) to measure CSF pressure. MRV and LP were also performed in 28 age-matched control subjects. RESULTS In all the control subjects, both MRV and CSF pressure were normal. One hundred three of the 114 patients with CDH had normal MRV. Twenty-seven (Group 1) of these 103 patients underwent LP, and all of them had normal CSF pressure. Eleven (9.6%) of the 114 patients with CDH had CVT of one or both transverse sinuses. Six of these 11 patients had flowing abnormalities of one transverse sinus (Group 2), whereas the remaining five patients showed involvement of both transverse sinuses (Group 3). The CSF pressure of Group 2 was higher than that of either Group 1 or the control subjects, and one of the six patients showed isolated IHWOP. Patients of Group 3 displayed the highest CSF pressure, and four of five had isolated IHWOP. The headache profiles of patients with CDH and CVT did not differ from those of patients with CDH but normal MRV. CONCLUSIONS CVT, as detected by MRV, occurred in 9.6% of patients who presented with CDH. Almost half of the patients with CVT had isolated IHWOP. These results suggest that MRV may be a useful tool for selecting patients with CDH who should have LP to exclude isolated IHWOP.

Abstract
We report theoretical and experimental results on the stabilization of unstable steady states in a CO2 laser with feedback. Periodic and chaotic oscillations have been suppressed by means of a control loop consisting of a high-pass filter, known as washout filter. Although the filter characteristics are determined on the basis of linear analysis, taking into account the problem of robustness with respect to parameter changes, the present control strategy provides a large attractive domain in the phase space.

Abstract
Zn absorption was investigated in healthy elderly subjects aged 71-78 years and in young subjects aged 23-43 years using serum concentration curve (SCC) tests. Both groups had similar Zn and protein status. The increase in serum Zn was monitored for 180 min after ingestion of 200 ml of soya milk enriched with 50 mg of Zn. Three levels of phytic acid were used: 0 g/200 ml (totally dephytinized soya milk), 0.13 g/200 ml (half dephytinized), and 0.26 g/200 ml (natural phytic acid content). In a first study the effect of 0 v. 0.26 g/200 ml phytic acid was compared in 10 elderly and 10 young subjects, each subject receiving both treatments. In a second study soya milks with 0 and 0.13 g/200 ml were tested in nine elderly and ten young subjects, again receiving both treatments. Mean areas under the curve of the SCC tests conducted with the 0 g/200 ml soya milk were found to be the same in both studies. Phytic acid strongly depressed Zn absorption in both studies (P < or = 0.05), but to a greater extent at the 0.26 g/200 ml level. No difference was found between the groups of young and elderly subjects. Therefore, no significant effect of aging on Zn absorption, as evaluated by the SCC test, or on the inhibitory effect of phytic acid was detected.

Abstract
We present the numerical and experimental study that we carried out to compare the performances of two hybrid stable-unstable resonators for diffusion-cooled CO(2) slab lasers. The two resonators are designed to fit a 320 mm × 60 mm ×2 mm rf-discharge channel and are both guided in the narrow transverse direction. They differ in the other transverse direction, consisting of a positive- or a negative-branch unstable resonator scheme. The two solutions have been characterized in terms of modal structure, power extraction, stability, and quality of the extracted beam.
