Abstract
The new challenge in the investigation of cultural heritage is the possibility to obtain stratigraphical information about the distribution of the different organic and inorganic components without sampling. In this paper recently commercialized analytical set-up, which is able to co-register VNIR, SWIR, and XRF spectral data simultaneously, is exploited in combination with an innovative multivariate and multiblock high-throughput data processing for the analysis of multilayered paintings. The instrument allows to obtain elemental and molecular information from superficial to subsurface layers across the investigated area. The chemometric strategy proved to be highly efficient in data reduction and for the extraction and integration of the most useful information coming from the three different spectroscopies, also filling the gap between data acquisition and data understanding through the combination of principal component analysis (PCA), brushing, correlation diagrams and maps (within and between spectral blocks) on the low-level fused. In particular, correlation diagrams and maps provide useful information for the reconstruction of a stratigraphic structure without the need to take any sample, thanks to the effective account for inter-correlation among data (variables), which is able to effectively characterize the possible combinations of components located in the same depth level. The highly innovative technology and the data processing strategy are applied for the multi-level characterization of a complex painting reproduction as an illustrative pilot study.

Abstract
We present a multi-analytical in situ non-invasive study of a series of emblematic paintings by Alessandro Milesi (1856-1945) from the collection of the International Gallery of Modern Art Ca' Pesaro in Venice. Eight paintings dated from 1897 to 1910 were studied with imaging and spectroscopic techniques. White pigments were characterized by a combination of X-ray fluorescence spectroscopy which traced the presence of zinc-based pigments in Milesi's paintings, Raman Spectroscopy, Laser Induced Fluorescence (LIF) Spectroscopy and Time-resolved Luminescence Imaging. Time-resolved analysis of luminescence emissions revealed the nanosecond emission from organic compounds and the slower emission from the luminescent inorganic pigment Zinc Oxide that varied between 1.1 and 1.6 microseconds. In this work, data regarding the distribution of luminescent pigments was acquired with a time-gated imaging detector. Furthermore, differences in emission decay kinetics recorded from different paintings can be ascribed to different paint formulations or origins of the Zinc white in paint.

Abstract
A complementary multi-analytical in-situ approach has been adopted for the investigation of a corpus of ten paintings dating from 1889 and 1940 by the Venetian painter Alessandro Milesi (1856-1945), from the collection of the International Gallery of Modern Art Ca' Pesaro in Venice. Analyses were performed in situ with digital imaging, elemental and spectroscopic analysis. The analysis of pigments and binding media and their possible deterioration patterns were studied with a combination of X-Ray Fluorescence (XRF) Spectroscopy, External Reflection- Fourier Transform Infrared Spectroscopy (ER-FTIR) and Raman Spectroscopy. These analytical methods provide information regarding the evolution of the artist's palette and the painting techniques adopted in painting. Data suggest the widespread detection of zinc carboxylates, with implications for conservation and display.

Abstract
The choice of the best sampling strategy to capture mean values of functional traits for a species/population, while maintaining information about traits' variability and minimizing the sampling size and effort, is an open issue in functional trait ecology. Intraspecific variability (ITV) of functional traits strongly influences sampling size and effort. However, while adequate information is available about intraspecific variability between individuals (ITVBI) and among populations (ITVPOP), relatively few studies have analyzed intraspecific variability within individuals (ITVWI). Here, we provide an analysis of ITVWI of two foliar traits, namely specific leaf area (SLA) and osmotic potential (π), in a population of Quercus ilex L. We assessed the baseline ITVWI level of variation between the two traits and provided the minimum and optimal sampling size in order to take into account ITVWI, comparing sampling optimization outputs with those previously proposed in the literature. Different factors accounted for different amount of variance of the two traits. SLA variance was mostly spread within individuals (43.4% of the total variance), while π variance was mainly spread between individuals (43.2%). Strategies that did not account for all the canopy strata produced mean values not representative of the sampled population. The minimum size to adequately capture the studied functional traits corresponded to 5 leaves taken randomly from 5 individuals, while the most accurate and feasible sampling size was 4 leaves taken randomly from 10 individuals. We demonstrate that the spatial structure of the canopy could significantly affect traits variability. Moreover, different strategies for different traits could be implemented during sampling surveys. We partially confirm sampling sizes previously proposed in the recent literature and encourage future analysis involving different traits.

Abstract
Osmotic agents are still the most common treatment for controlling intracranial hypertension (ICH). Mannitol, glycerol, sorbitol, and hypertonic serum saline are the agents currently available. This work was designed to compare mannitol and glycerol in a similar population of brain injured patients, randomly divided into two groups of eight. The following mean day parameters were obtained: number of infusions, hydric balance, mean arterial pressure (MAP), and intracranial pressure (ICP). Cerebral perfusion pressure (CPP) was calculated. Brain computed tomographies (CT) were obtained on arrival, at follow-up whenever justified and at discharge. For comparison of both groups a modified therapeutic intensity level (mTIL) was used. Both agents induced a statistically equally effective decrease on ICP and increase on CPP evaluated at one and two hours post infusion but the mean day mTIL showed a statistically significant difference in favour of glycerol. The possible explanations of this difference are discussed. According to our results mannitol would be most indicated as a bolus to control sudden rises in ICP whereas glycerol would be most indicated as a basal treatment.

Abstract
OBJECTIVES To investigate the hypothesis that psychiatric disturbances in Huntington's disease are related to degree of cognitive or motor compromise and to determine correlations between CAG repeat length within the gene for Huntington's disease and disease severity. DESIGN Consecutive series of patients with Huntington's disease. SETTING Neurological specialty hospital. PATIENTS Seventeen men and 12 women from 24 families. MAIN OUTCOME MEASURES The Hamilton Psychiatric and Anxiety Rating Scales and Brief Psychiatric Rating Scale were used to assess psychiatric disturbances; Folstein's Quantified Neurological Examination to evaluate motor status; and the Mini-Mental State Examination, Raven Progressive Matrices), Phonemic Verbal Fluency Test, Short Tale Test, Visual Search Test, and Benton's Visual Orientation Line Test to evaluate cognitive function. The length of the CAG repeat sequence in the Huntington's gene was determined by quantitative polymerase chain reaction. RESULTS Cognitive test scores correlated significantly with each other; of these, results of the Visual Search and Short Tale tests correlated significantly with the Folstein's Quantified Neurological Examination score (P = .05 and P = .03, respectively). Results of the Folstein's Quantified Neurological Examination also correlated with the illness duration and the length of the CAG repeat. Although psychiatric scores correlated significantly among themselves (P < .01), neither cognitive compromise, motor deterioration, nor CAG length were related to the extent of psychiatric compromise. Patients who were depressed when they were examined tended to have a history of psychiatric disorders. CONCLUSIONS The lack of correlation between disease severity and psychiatric disturbances indicates that psychiatric disorders progress nonlinearly, possibly because of differential degeneration of the striatal-cortical circuits; the possibility that psychiatric disorders are prevalent in certain families with a member who has Huntington's disease is being further investigated. The lack of correlation between CAG length and cognitive and psychiatric variables needs further investigation.

Abstract
This study was conducted on fine-needle aspirates of well differentiated follicular neoplasms of the thyroid. A 'decision tree' classification based on the percentage of nucleolated nuclei, percentage of nuclei with two or more nucleoli and mean major nuclear diameter was adopted. We observed that the reproducibility and the validity of the follicular adenoma vs follicular carcinoma discrimination are greater than in the subjective evaluation. Moreover, similar classification results were obtained when measurements were performed either with a fully automated image analysis system or with semiautomatic or manual instrumentation. As for reproducibility of the inter-instrument comparisons, the k statistic values ranged from 0.85 to 1.00 (mean value 0.90, that is, an 'almost perfect' degree of agreement); in the subjective evaluations, the inter-observer comparisons showed values ranging from 0.20 to 0.56 (mean value 0.37, that is, 'fair'). In the decision tree classification, feature value thresholds were selected in order to have specificity of 100% and the predictive value of a positive result (carcinoma) of 100%; accuracy was 87% (range 86-89%), sensitivity 74% (71-79%), the predictive value of a negative result (adenoma) 79% (78-82%). In the subjective evaluation the values were as follows: accuracy 67% (64-71%), sensitivity 57% (50-64%), specificity 77% (71-79%), predictive value of a negative result (adenoma) 64% (61-69%), predictive value of a positive result (carcinoma) 71% (67-75%). The conclusion is that, by using a routine microscope equipped with a micrometer, the preoperative diagnosis of follicular carcinoma from smears can be formulated with a high degree of certainty.

Abstract
The study was done on cytologic material of 58 non-oxyphil follicular neoplasias of the thyroid, 32 of which were adenomas and 26 carcinomas. Three groups of nucleolar features were quantified using a routine microscope with an ocular micrometer: frequency-, size-, and margination-related features. Since value overlap was present between two categories for all the variables, stepwise discriminant analysis was applied. The following three features were selected by the computer for calculation of one canonical discriminant function: percentage of marginated nucleoli, percentage of nuclei with one nucleolus, mean major nucleolar diameter. The percentage of agreement between morphologic and computer classifications was 95%. Two follicular adenomas were allocated to the carcinoma category, whereas one follicular carcinoma was allocated to the adenoma category. Out of 58, 52 were diagnosed by the computer into one of the two diagnostic categories with a very high probability, i.e. P greater than 0.75, the remaining 6 being considered intermediate.

Abstract
Image analysis was performed on 40 Feulgen-stained histologic samples and 48 Feulgen-stained cytologic preparations representing normal squamous epithelium and all grades of cervical lesions (from mild dysplasia to invasive carcinoma) in order to characterize the evolutionary progressive changes in cervical epithelial proliferative disease toward malignancy. Quantitative studies included the analysis of proliferative features, differentiation features, nuclear morphology and DNA content. The data obtained on the histologic sections showed that the various features, to a different extent, detected a gradual increase in phenotypic cellular disarrangements related to the progression of the cervical lesions toward malignancy--that is, the modifications to nuclear area, perimeter, DNA content, percentage of nuclei with nucleoli, nuclear/cytoplasmic ratio and percentage of cells with no membrane positivity for soybean agglutinin lectin were progressively greater, moving from normal epithelium and mild dysplasia toward infiltrating carcinoma. In particular, all the morphologic and histochemical features appeared to parallel a diploid reduction and the appearance of aneuploidy. The simultaneous evaluation of proliferation- and differentiation-related features, together with those of nuclear DNA content, showed two main successive preneoplastic lesions: one characterized by an increase in cell turnover without alterations in its organization and another by a true neoplastic disorder. The data obtained on sequential cytologic examinations showed that individual cell changes are detectable and seem basically to be characterized by the appearance of clusters of cells with somatic characteristics not observed in previous cytologic checks. From the results of our study, the cervical intraepithelial neoplasia (CIN) concept appears to be inaccurate. In fact, only CIN III (severe dysplasia/carcinoma in situ) lesions have the morphologic and proliferative alterations of true neoplasia. In contrast, CIN I and some cases of CIN II lesions lack these characteristics and seem to be properly classified as dysplasia, thus avoiding the term neoplasia, implicit in CIN. Moreover, the multivariate study of data sets of features related to the progressive somatic changes, both in histologically and cytologically studied cases, allows us to detect the steps of progression; they are marked by the appearance of cell clusters with qualitatively different phenotypic characters when compared to the cell populations from which they presumably arise. These results seem to provide a further argument against the CIN theory, which stresses the concept that progression is related only to a gradual numerical increase in an initially established phenotype with the characteristics of malignancy.

Abstract
The diagnostic value of nucleolar margination, defined as the percentage of nucleoli touching the nuclear membrane, was investigated in 359 cytological preparations of benign and malignant lesions of the thyroid, breast, prostate and central nervous system. Premalignant lesions of the uterine cervix and non-invasive papillary carcinomas of the bladder were also examined. It was observed that the percentages in benign lesions were, in general, lower than in the malignant and that the values increased progressively with increasing grade in the cervix and bladder. When the overlap index was calculated, this gave exact information on the usefulness of nucleolar margination in distinguishing benign from malignant lesions, particularly in the prostate and thyroid and, to a lesser extent, in the breast and central nervous system. As for lesions of different grades, the calculation of the index allowed the identification of two subgroups, one corresponding to low grades (mild cervical dysplasia or urothelial papillary carcinoma of grade 1), the other subgroup to high grades (severe cervical dysplasia and carcinoma in situ, or papillary carcinoma of grade 3). Moderate dysplasia cases and grade 2 papillary carcinomas do not appear as separate intermediate categories but rather show values falling into the range of either the higher or lower grades. The margination values obtained from the cytological preparations corresponded well to those in the histological slides obtained from the resected specimens. In conclusion, nucleolar margination appears to be a feature which is easy to evaluate in a reproducible way and useful in cytological diagnosis.

Abstract
Nucleolar prevalence, size, and outline were investigated on cytological material from cold thyroid nodules obtained by fine needle aspiration. The percentage of nucleolated nuclei in follicular adenoma (32 cases) was less than in follicular carcinoma (26 cases). In adenoma most nuclei contained one nucleolus, and nuclei with two or more nucleoli were less common than in carcinoma where most cases showed the highest nucleolar diameter values. There was some overlap between adenomas and carcinomas, however, when the mean of the 10 largest values of the major nucleolar diameter was considered. In follicular carcinoma the percentage of marginated nucleoli--that is, those touching the nuclear membrane--was, in general, greater than 20%; in adenoma the values were equal to or lower than 16%. The overlap index showed that the percentages of marginated nucleoli and nucleolated nuclei are the two best discriminatory features between adenoma and carcinoma.

Abstract
The changes in nuclear morphology (karyometry) and DNA content in prostatic intraepithelial neoplasia (PIN) were analyzed on tissue sections. The cases of PIN were subdivided into PIN 1 and PIN 2 based on the degree of proliferation and the anaplasia of the secretory cells lining the ducts and acini. Cases of nodular hyperplasia (NH) and adenocarcinoma were also studied for comparative purposes. Karyometric analysis showed a progression of most values from NH to PIN to carcinoma. The DNA analysis showed a decrease in the frequency of nuclei in the diploid range and an increase in the percentage of nuclei in the other ploidy regions (especially between 2c and 4c and in the tetraploid range) from NH to PIN to carcinoma. Forward stepwise discriminant analysis showed similarities between NH and PIN 1 and between PIN 2 and carcinoma. These findings suggest that the evolution towards adenocarcinoma is characterized by progressive morphologic derangements of the nuclei and by the transformation of the diploid DNA content into a nondiploid one, with the changes taking place at the level of PIN 2.

Abstract
The slides of fine needle aspiration cytology specimens from 99 cases of cold thyroid nodules with known histology were reviewed and the number of nucleoli per nucleus counted and correlated with the different histopathological groups. Significant differences were observed between benign and malignant thyroid lesions in the number of nucleoli in the cytological material. Lower values were present in nodular goitres and follicular adenomas compared to carcinomas. In benign lesions the majority of nuclei contained one nucleolus and nuclei with two, three or more nucleoli were less frequent than in follicular, papillary, medullary and anaplastic carcinomas. Only one case of follicular adenoma had cells containing three or more nucleoli compared to more than half the cases of follicular carcinoma.

Abstract
Our experience concerning 605 fine needle aspiration (FNA) biopsies performed between 1985 and 1988 is reported. FNA specimens of the prostate gland were compared to histological material in 101 cases: 37 patients underwent suprapubic prostatectomy, 15 radical prostatectomy, 28 transurethral resection, and 21 core needle biopsies. Adenocarcinoma was correctly diagnosed by using cytology in 39 out of 40 cases; benign prostatic hypertrophy was confirmed by histology in 54 out of 57 cytologically benign cases. The absolute sensitivity of the FNA biopsy was 98.2%; specificity was 98.1%; efficiency was 96%; and false negative rate was 6.6%. Our data support the value of transrectal aspiration biopsy as a precise and easy method for diagnosing prostatic cancer; the low false negative rate and the high number of correct diagnoses underline the great accuracy of the method.

Abstract
In connection with the surveillance programme of congenital malformations in Emilia Romagna led by I.M.E.R. Group since 1978 a crosswise survey has been performed on selected malformations: Down's syndrome, cardiac defects, unilateral or bilateral cleft lip and/or palate, unilateral or bilateral club foot. This survey has been useful as a pilot-study for another longitudinal survey which had a place in the programmes of the C.N.R. (National Research Council). By means of a multi-discipline approach we have collected information both of pediatric and of psycho-social character. A total of 187 children with the above named malformations were recorded at birth, 106 boys and 81 girls, aged from 9 months to 4 years. The neonatal diagnosis was confirmed in 84 out 86 cases under study. The rate of infant mortality was particularly high among children with heart defects (39.1%) and Down children (27.4%). The surgical centres where these children were operated upon, through with large variations in connection with the type of malformation, were in Emilia Romagna (49%), outside it (40%), and abroad (10.9%). As for the parental reaction to the birth of babies with congenital malformations, it was of initial rejection 5 cases of Down children, 3 cases of cardiopathy and 1 case of cleft lip and palate. Later the refusal was permanently confirmed only in 2 cases of Down children (who were subsequently adopted). The birth of a malformed baby has affected the relationship between husband and wife contributing to the separation in 3 cases of Down's syndrome and in 1 case of cardiopathy.

Abstract
The authors analysed the long-term results of 72 subtrochanteric fractures treated surgically over a period of 13 years. The case material was subdivided according to type of fracture and method of osteosynthesis and the results were evaluated with a view to ascertaining the best method of treatment in each type of fracture. The best results were obtained with osteosynthesis using an angled nail plate.

Abstract
A study has been made on the modifications that appear after acute dosage of pirenzepine in a series of eight healthy subjects of both sexes who had shown, by radioisotopic evaluation, a physiological pattern of gastric kinetics. The acute dosage of the drug was continued for three days at therapeutic doses and, a few hours after the last administration, the same study was repeated. As a test meal, a whole fried egg containing 99mTc-labelled serum albumin was used. The kinetics of the gastric content was scanned by a gamma-camera. The difference in gastric kinetics between the baseline situation and that after administration of the drug is reported and discussed.

Abstract
In time course experiments performed in subjects carrying haemoglobin Hasharon and beta-thalassaemia the synthesis of alphaA-, alphaHasharon-, beta- and gamma-globin has been determined. The alpha-globin molecules synthesized in excess were found to be removed from the red cell cytoplasm (phenomenon characteristic of beta-thalassaemia, described by Bargellesi et al, 1968a); in addition the alphaHasharon-globin molecules were removed at a faster rate than normal alpha-globin. The preferential removal of the mutant alpha-globin explains the reduced level of haemoglobin Hasharon found in subjects carrying the gene for beta-thalassaemia (Alberti et al, 1975). Reductions below normal levels of other haemoglobin variants occurring in the presence of the counterpart-globin thalassaemia are probably determined through a similar mechanism.

Abstract
During a survey for abnormal hemoglobins in Polesine (a region north of the Po river, where beta-thalassemia is very frequent) a slow moving variant was noted in a 79-yr-old woman living in Gavello, a small town in the province of Rovigo. Structural studies demonstrated a previously undescribed amino acid substitution, beta47 Asp replaced by Gly. This new variant has been named Hb Gavello.

Abstract
A survey of haemoglobin variants undertakin in an Italian community (Polesine) has revealed the presence of haemoglobin Hasharon (alpha2 47 Asp yields His beta2) in 108 subjects from 40 families. The variant accounted for 30 to 40% of the total haemoglobin. In subjects doubly heterozygous for Hb Hasharon and beta thalassaemia, the proportion was 17 to 19%. Though there was some evidence that the variant was unstable in vitro, there was no obvious haemoglobinopathy in vivo.
