Abstract
A relevant percentage of breast cancers (BCs) are tied to pathogenetic (P)/likely pathogenetic (LP) variants in predisposing genes. The knowledge of P/LP variants is an essential element in the management of BC patients since the first diagnosis because it influences surgery and subsequent oncological treatments and follow-up. Moreover, patients with metastatic BCs can benefit from personalized treatment if carriers of P/LP in BRCA1/2 genes. Multigene panels allow the identification of other predisposing genes with an impact on management. Cascade genetic testing for healthy family members allows personalized preventive strategies. Here, we review the advances and the challenges of Cancer Genetic Counseling (CGC). We focus on the area of oncology directed to hereditary BC management describing the peculiar way to lead CGC and how CGC changes over time. The authors describe the impact of genetic testing by targeted approach or universal approach on the management of BC according to the stage at diagnosis. Moreover, they describe the burden of CGC and testing and future perspectives to widely offer testing. A new perspective is needed for models of service delivery of CGC and testing, beyond formal genetic counselling. A broader genetic test can be quickly usable in clinical practice for comprehensive BC management and personalized prevention in the era of precision oncology.

Abstract
OBJECTIVE Adrenocortical carcinoma (ACC) has an aggressive but variable clinical course. Prognostic stratification based on the European Network for the Study of Adrenal Tumours stage and Ki67 index is limited. We aimed to demonstrate the prognostic role of a points-based score (S-GRAS) in a large cohort of patients with ACC. DESIGN This is a multicentre, retrospective study on ACC patients who underwent adrenalectomy. METHODS The S-GRAS score was calculated as a sum of the following points: tumour stage (1-2 = 0; 3 = 1; 4 = 2), grade (Ki67 index 0-9% = 0; 10-19% = 1; ≥20% = 2 points), resection status (R0 = 0; RX = 1; R1 = 2; R2 = 3), age (<50 years = 0; ≥50 years = 1), symptoms (no = 0; yes = 1), and categorised, generating four groups (0-1, 2-3, 4-5, and 6-9). Endpoints were progression-free survival (PFS) and disease-specific survival (DSS). The discriminative performance of S-GRAS and its components was tested by Harrell's Concordance index (C-index) and Royston-Sauerbrei's R2D statistic. RESULTS We included 942 ACC patients. The S-GRAS score showed superior prognostic performance for both PFS and DSS, with best discrimination obtained using the individual scores (0-9) (C-index = 0.73, R2D = 0.30, and C-index = 0.79, R2D = 0.45, respectively, all P < 0.01vs each component). The superiority of S-GRAS score remained when comparing patients treated or not with adjuvant mitotane (n = 481 vs 314). In particular, the risk of recurrence was significantly reduced as a result of adjuvant mitotane only in patients with S-GRAS 4-5. CONCLUSION The prognostic performance of S-GRAS is superior to tumour stage and Ki67 in operated ACC patients, independently from adjuvant mitotane. S-GRAS score provides a new important guide for personalised management of ACC (i.e. radiological surveillance and adjuvant treatment).

Abstract
Adrenocortical carcinoma (ACC) is an aggressive cancer characterized by poor survival. Apart from radical surgery, there is a limited range of therapeutic options and mitotane remains the cornerstone of medical treatment of ACC in either adjuvant or palliative settings. The aim of adjuvant mitotane therapy is to reduce the risk of ACC recurrence following surgical removal of the tumor. Use of mitotane in an adjuvant setting is off-label, but the recent guidelines endorsed by the European Society of Endocrinology (ESE) and the European Network for the Study of Adrenal Tumors (ENSAT) recommend it in ACC patients at high risk of recurrence. The palliative use of mitotane for treatment of advanced ACC aims at controlling tumor progression and, when present, hormone secretion. In this clinical setting, mitotane is used in association with chemotherapy to treat the more aggressive forms, while mitotane monotherapy is reserved for less progressive ACC. Many years after its introduction in clinical practice, there are still uncertainties surrounding the use of this old drug and the derived benefits. Moreover, physicians who use mitotane should recognize and manage the systemic effects of the drug that need a complex supporting therapy.

Abstract
Objective Many patients with adrenocortical carcinoma (ACC) suffer from tumor recurrence despite radical surgery. Evidence on the post-operative use of mitotane is controversial and no predictors of response are available. We aimed to assess whether adjuvant mitotane treatment may prolong survival in patients with non-metastatic ACC following complete resection and whether ACC patients at high risk of recurrence may benefit from treatment. Design and methods We retrospectively reviewed data from 152 non-metastatic ACC patients followed at the San Luigi Gonzaga Hospital: 100 patients were treated with adjuvant mitotane and 52 patients were left untreated following surgery. We assessed a number of potential predictive factors of recurrence and death. Mitotane effect was explored stratifying patients by staging (stage I-II vs stage III), hormone secretion (yes vs no) and Ki67 index. Results The non-treated group had a higher risk of recurrence (HR: 2.79, 95%CI: 1.58-4.91; P < 0.001) than mitotane-treated group, while overall survival was not significantly different between groups. Hormone secretion, elevated Weiss score and elevated Ki67 index confer a higher risk of both recurrence and death and stage III ACC of death. Adjuvant mitotane treatment reduced significantly the risk of death in patients with elevated Ki67 index (P = 0.005) and in patients with stage III ACC (P = 0.02). Conclusions Adjuvant mitotane may prolong recurrence-free survival in radically resected ACC patients with acceptable toxicity and may also prolong overall survival in a subgroup of ACC patients at high risk of recurrence.

Abstract
PURPOSE To assess the incidence of extrusion and infections of encircling silicone sponges in scleral buckling surgery for retinal detachment with and without the use of an intraoperative antibiotic soaking procedure. METHODS The authors performed a retrospective analysis reviewing the charts of 1127 patients who underwent episcleral buckling surgery operated by the same surgeon in three different institutions during a period of 11 years. The authors reviewed the charts of patients treated with a single episcleral silicone sponge (Labtician) indentation in three different models. The infection prophylaxis on the operating field was the same in all cases and only since February 1997 was the silicone sponge preoperatively treated with an antibiotic soaking procedure. RESULTS No immediate postoperative infections were reported in the operated eyes. Three eyes had an implant extrusion and in all these cases silicone sponge removal was performed. All three extrusion cases developed when sponge soaking was not adopted. CONCLUSIONS The data indicate that the soaking procedure does not decrease extrusion and infection incidence in scleral buckling surgery when both accurate surgical technique and disinfection prophylaxis are performed.

Abstract
For two nights 10 subjects were asked to recall their mental sleep experience after experimental awakening during REM sleep (night report) and again upon spontaneous morning awakening (morning report). The two types of report were subjected to linguistic analysis and compared. The number of sentences used to describe the mental sleep experience, their syntactic structures, and over-all report length were similar. Those contents common to both reports were in both cases encoded in about one fourth of the sleep-related kernel sentences, these kernel sentences being distributed over about two-thirds of the sentences of the report, generally the longer ones. The organization of the morning reports reflects the consolidation of the contents in memory. The only significant physiological variable, waking time, was negatively correlated to the numbers of kernel sentences and sentences reproducing contents previously encoded in the night reports. The organization of the morning report primarily appears to be the result of retrieval and encoding procedures relative to the mental sleep experience preceding the night awakening rather than simply to the encoded contents of the night report.

Abstract
AIM The primary aim of this study was to examine the effects of intensive periodontal therapy on HbA(1c) in a mixed diabetes mellitus (DM) (types 1 and 2) population with moderate periodontitis (PD). METHODS A total of 93 subjects with PD and DM, recruited from referrals to the Department of Endocrinology at the Perugia Hospital, were included in a follow-up cohort clinical study comprising two parallel periodontal therapy groups-one receiving intensive periodontal therapy (IPT, n=44) and the other serving as controls (CPT, n=49)-with an 8-month follow-up. Clinical periodontal examinations and blood samples were collected 4 and 8 months after the completion of therapy. RESULTS The IPT group presented with greater reductions of all periodontal indices compared with the CPT group at both follow-ups (P<0.001). Whereas, after 4 months, there were no major differences in HbA(1c) levels between groups, after 8 months, the IPT group presented with a 0.57% (95% CI: 0.12 to 1.09) greater reduction in HbA(1c) than the CPT group (P=0.03). This reduction was independent of age, gender, smoking and body mass index. However, the difference in HbA(1c) was greater in individuals with type 2 DM (0.95% reduction, 95% CI: 0.32 to 1.58; P=0.004) compared with those with type 1 DM. CONCLUSION IPT resulted in greater improvement of gingival health in patients with DM. Improved oral health in those with type 2 DM may have an effect on medium-term glucose management and could possibly lead to long-term health benefits. (ISRCTN00559156).

Abstract
Human T-cell lymphotropic virus (HTLV)-1 is associated with a chronic progressive neurologic disease known as HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) that affects 0.2% to 3% of HTLV-1-infected people. The authors aimed at exploring, in vivo, whether brain volume reduction occurs in patients with HAM/TSP through the use of magnetic resonance imaging (MRI). T1 pre/postcontrast spin echo-weighted images (WIs) and T2WIs of the brain were obtained in 19 HAM/TSP patients and 14 age-and sex-matched healthy volunteers. Both patients and healthy individuals were imaged at a 1.5-Tesla magnet by employing a conventional head coil. Focal T1 and T2 abnormalities were calculated and two measurements of brain parenchyma fraction (BPF) were obtained by using SIENAx (Structural Image Evaluation,using Normalisation, of Atrophy; University of Oxford, Oxford, UK) and MIPAV (Medical Image Processing, Analysis, and Visualization; National Institutes of Health, Bethesda, USA) from T1WIs. No significant differences in BPF were found between patients and healthy subjects when using either SIENAx or MIPAV. Analysis of individual patients detected that BPF was lower by 1 standard deviation (SD) relative to patients' average BPF in one patient. The authors conclude that reductions in BPF do not occur frequently in patients with HAM/TSP. However, the authors believe that one individual case of significant brain atrophy raises the question as to whether atrophy selectively targets the spinal cord of HAM/TSP patients or may involve the brain as well. A larger patient population analyzing regional brain volume changes could be helpful in determining whether brain atrophy is a marker of disease in patients with HAM/TSP.

Abstract
Pancreatic beta-cells are connected by gap junction channels made of a connexin protein, referred to as Cx36. Through these channels, beta-cells are coupled to each other, i.e. exchange cytoplasmic ions and small metabolites. Previous experiments have indicated that these exchanges are important for coordinating the function of individual cells within pancreatic islets, particularly with regard to glucose-induced insulin secretion. Advances in molecular biology, genetics and mouse transgenic approaches allow now for a direct experimental testing of this mechanism in vitro as well as in vivo. Recent experiments in rodent and culture models suggest that connexin-dependent cell-to-cell crosstalk is a significant player in the multifactorial regulation of insulin secretion and, possibly, of other beta-cell functions, such as growth. Elucidating the still obscure mechanism whereby connexin signalling exerts this influence will provide insights on the contribution of direct cell-to-cell interactions in the physiological regulation of beta-cell life. The presence of Cx36 within human pancreatic islets, raises the further challenge to determine whether a dysfunction of connexin signaling may contribute to the pathophysiology of beta-cell dysfunctions in type I and/or type II diabetes. Efforts to understand the functions of beta-cell connexins are also a prerequisite for the engineering of surrogate cells and their proper tridimensional packaging, which are instrumental for the future implementation of a replacement cell therapy in diabetic patients.

Abstract
The aim of this work is the evaluation, on a pilot scale, of scrap tyre pyrolysis process performance and the characteristics of the products under different process parameters, such as temperature, residence time, pressure, etc. In this frame, a series of tests were carried out at varying process temperatures between 550 and 680 degrees C, other parameters being equal. Pyrolysis plant process data are collected by an acquisition system; scrap tyre samples used for the treatment, solid and liquid by-products and produced syngas were analysed through both on-line monitoring (for gas) and laboratory analyses. Results show that process temperature, in the explored range, does not seem to seriously influence the volatilisation reaction yield, at least from a quantitative point of view, while it observably influences the distribution of the volatile fraction (liquid and gas) and by-products characteristics.

Abstract
The secretory, duct, connective and vascular cells of pancreas are connected by gap junctions, made of different connexins. The insulin-producing beta-cells, which form the bulk of endocrine pancreatic islets, express predominantly Cx36. To assess the function of this connexin, we have first studied its expression in rats, during sequential changes of pancreatic function which were induced by the implantation of a secreting insulinoma. We observed that changes in beta-cell function were paralleled by changes in Cx36 expression. We have also begun to investigate mutant mice lacking Cx36. The absence of this protein did not affect the development and differentiation of beta-cells but appeared to alter their secretion. We have studied this effect in MIN6 cells which spontaneously express Cx36. After stable transfection of a construct that markedly reduced the expression of this connexin, we observed that MIN6 cells were no more able to secrete insulin, in contrast to wild type controls, and differentially displayed a series of still unknown genes. The data provide evidence that Cx36-dependent signaling contributes to regulate the function of native and tumoral insulin-producing cells.

Abstract
Articular cartilage is a tissue designed to withstand compression during joint movement and, in vivo, is subjected to a wide range of mechanical loading forces. Mechanosensitivity has been demonstrated to influence chondrocyte metabolism and cartilage homeostasis, but the mechanisms underlying mechanotransduction in these cells are poorly understood. In many cell types mechanical stimulation induces increases of the cytosolic Ca2+ concentration that propagates from cell to cell as an intercellular Ca2+ wave. Cell-to-cell communication through gap junctions underlies tissue co-ordination of metabolism and sensitivity to extracellular stimuli: gap junctional permeability to intracellular second messengers allows signal transduction pathways to be shared among several cells, ultimately resulting in co-ordinated tissue responses. Mechanically-induced Ca2+ signalling was investigated with digital fluorescence video imaging in primary cultures of rabbit articular chondrocytes. Mechanical stimulation of a single cell, obtained by briefly distorting the plasmamembrane with a micropipette, induced a wave of increased Ca2+ that was communicated to surrounding cells. Intercellular Ca2+ spreading was inhibited by 18 alpha-glycyrrhetinic acid, suggesting the involvement of gap junctions in signal propagation. The functional expression of gap junctions was assessed, in confluent chondrocyte cultures, by the intercellular transfer of Lucifer yellow dye in microinjection experiments while the expression of connexin 43 could be detected in Western blots. A series of pharmacological tools known to interfere with the cell calcium handling capacity were employed to investigate the mechanism of mechanically-induced Ca2+ signalling. In the absence of extracellular Ca2+ mechanical stimulation induced communicated Ca2+ waves similar to controls. Mechanical stress induced Ca2+ influx both in the stimulated chondrocyte but not in the adjacent cells, as assessed by the Mn2+ quenching technique. Cells treatment with thapsigargin and with the phospholipase C inhibitor U73122 blocked mechanically-induced signal propagation. These results provide evidence that in chondrocytes mechanical stimulation activates phospholipase C, thus leading to an increase of intracellular inositol 1,4,5-trisphosphate. The second messenger, by permeating gap junctions, stimulates intracellular Ca2+ release in neighbouring cells. Intercellular Ca2+ waves may provide a mechanism to co-ordinate tissue responses in cartilage physiology.

Abstract
Proper insulin secretion requires the coordinated functioning of the numerous beta cells that form pancreatic islets. This coordination depends on a network of communication mechanisms whereby beta cells interact with extracellular signals and adjacent cells via connexin channels. To assess whether connexin-dependent communication plays a role in vivo, we have developed transgenic mice in which connexin 32 (Cx32), one of the vertebrate connexins found in the pancreas, is expressed in beta cells. We show that the altered beta-cell coupling that results from this expression causes reduced insulin secretion in response to physiologically relevant concentrations of glucose and abnormal tolerance to the sugar. These alterations were observed in spite of normal numbers of islets, increased insulin content, and preserved secretory response to glucose by individual beta cells. Moreover, glucose-stimulated islets showed improved electrical synchronization of these cells and increased cytosolic levels of Ca(2+). The results show that connexins contribute to the control of beta cells in vivo and that their excess is detrimental for insulin secretion.

Abstract
Instantaneous growth rates of young-of-the-year winter flounder Pseudopleuronectes americanus (Walbaum) (12.0-60.4 mm standard length, SL) and tautog Tautoga onitis (Linnaeus) (21.4-73.8 mm total length, TL) from three estuarine systems in New Jersey (Great Bay-Little Egg Harbor and Navesink River) and Connecticut (Hammonasset River) were used in an attempt to assess the relative quality of selected nominal habitats. A series of short-term field caging experiments were conducted during 1994 and 1995 in: macroalgae (primarily, Ulva lactuca), eelgrass (Zostera marina), unvegetated areas adjacent to macroalgae and eelgrass and tidal creeks in Spartina dominated marsh. Growth rates varied with habitat, estuary and year. Comparisons across nominal habitats within and among estuaries did not show any one habitat with consistently higher growth, and growth was relatively independent of whether a habitat was vegetated or adjacent to vegetation. The growth rates of winter flounder and tautog from the Hammonasset River were not different among habitats in either year of the study. In the Great Bay-Little Egg Harbor, both winter flounder and tautog had higher growth rates in macroalgae with growth in eelgrass varying significantly between years. Conversely, in the Navesink River both species had higher growth rates in eelgrass. Environmental changes associated with temperature and dissolved oxygen appeared to influence growth rates. Winter flounder growth rate and survival was depressed in tidal marsh creeks in the three estuaries and in vegetated macroalgae habitats in the Navesink River where dissolved oxygen levels were often very low (<2 mgl(-1)) for extended periods. In summary, the growth rates of the young-of-the-year of these two species varied temporally and were dependent on the interaction of both the specific estuary and habitat in which the experiments took place. Further, habitat quality, as defined by relative growth rate, was difficult to evaluate because it can be variable and nominal habitat designations are often not sufficient to define the boundaries of a species habitat requirements.

Abstract
The Sonority Dispersion Principle (Clements, 1990) states that the sharper the rise in sonority between the beginning of the syllable and the nucleus, the better the syllable. So far evidence in favour of this principle has been derived mainly from the distributional properties of syllable types and, to a lesser extent, from language acquisition. The case of DB, presented in this study, provides strong evidence that the Sonority Dispersion Principle also applies to an explanation of aphasic errors and revives Jakobson's idea that the same principles of complexity can explain the distribution of syllables, language acquisition, and language loss (Jakobson, 1941, 1968). Although some evidence that sonority constraints aphasic errors has been presented before, this is the first study reporting systematic effects of sonority-based complexity in aphasia.

Abstract
Intercellular communication through gap junctions allows tissue coordination of cell metabolism and sensitivity to extracellular stimuli. Intercellular Ca2+ signaling was investigated with digital fluorescence video imaging in primary cultures of articular chondrocytes and in HIG-82 synovial cells. In both cell types, mechanical stimulation of a single cell induced a wave of increased Ca2+ that was communicated to surrounding cells. Intercellular Ca2+ spreading was inhibited by 18alpha-glycyrrhetinic acid, demonstrating the involvement of gap junctions in signal propagation. In the absence of extracellular Ca2+, mechanical stimulation induced communicated Ca2+ waves similar to controls; however, the number of HIG-82 cells recruited decreased significantly. Mechanical stress induced Ca2+ influx both in the stimulated chondrocyte and HIG-82 cell, but not in the adjacent cells, as assessed by the Mn2+ quenching technique. Treatment of cells with thapsigargin and with the phospholipase C (PLC) inhibitor U73122 blocked mechanically induced signal propagation. These results provide evidence that in chondrocytes and in HIG-82 synovial cells, mechanical stimulation activates PLC, thus leading to an increase of intracellular inositol 1,4,5-trisphosphate. The second messenger, by permeating gap junctions, stimulates intracellular Ca2+ release in neighboring cells. It is concluded that intercellular Ca2+ waves may provide a mechanism to coordinate tissue responses in joint physiology.

Abstract
Intercellular communication allows the co-ordination of cell metabolism between tissues as well as sensitivity to extracellular stimuli. Paracrine stimulation and cell-to-cell coupling through gap junctions induce the formation of complex cellular networks that favour the intercellular exchange of nutrients and second messengers. Heterologous intercellular communication was studied in co-cultures of articular chondrocytes and HIG-82 synovial cells by measuring mechanically induced cytosolic changes in Ca2+ ion levels by digital fluorescence video imaging. In confluent co-cultures, mechanical stimulation induced intercellular Ca2+ waves that propagated to both cell types with similar kinetics. Intercellular wave spreading was inhibited by 18alpha-glycyrrhetinic acid and by treatments inhibiting the activation of purinoreceptors, suggesting that intercellular signalling between these two cell types occurs both through gap junctions and ATP-mediated paracrine stimulation. In rheumatoid arthritis the formation of the synovial pannus induces structural changes at the chondrosynovial junction, where chondrocyte and synovial cells come into close apposition: these results provide the first evidence for direct intercellular communication between these two cell types.

Abstract
The possibility of increasing Hb F in vivo using drugs like 5-azacytidine, hydroxyurea, and butyrate has been established. However, in many cases this does not entail an increase in total hemoglobin. We report on a patient with Hb Lepore/beta-thalassemia being treated with hydroxyurea (30 mg/Kg/day) because of the presence of erythroid extramedullary masses with severe neurological abnormalities. During therapy the patient showed a remarkable improvement in neurological signs due to the reduction in extra-medullary masses, a significant increase in both total hemoglobin (from 5.8 to 9.7 g/dl) and Hb F (from 4.9 g/dl to 9.1 g/dl). The marked improvement in hemoglobin level in our patient with Hb Lepore/beta-thalassemia suggests gamma-globin gene activation due to the DNA structure determined by the crossover event.

Abstract
Because of continuous blood transfusions, thalassemia patients are subjected to peroxidative tissue injury by the secondary iron overload. In accordance, analysis of serum from 42 beta-thalassemia patients, aged 4 to 40 years, showed that the mean concentrations of conjugated diene lipid hydroperoxides (CD), lipoperoxides evaluated as malondialdehyde/ thiobarbituric acid (MDA/TBA) adducts, and protein carbonyls increased about twofold with respect to control. Ferritin levels were positively correlated with the amount of MDA (r = .41; P = .007) and showed a positive trend with CD (r = .31; P = .07) and protein carbonyls (r = .35; P = .054), as further evidence of the deleterious effects of high tissue iron levels. Marked changes in the antioxidant pattern were also observed in all patients. Evidence is presented of a net drop in the concentration of ascorbate (-44%), vitamin E (-42%), vitamin A(-44%), beta-carotene (-29%), and lycopene (-67%). On the other hand, an increase of uric acid and bilirubin was observed, whereas serum albumin and glutathione were in the normal range in all patients. As a result, the total serum antioxidant potential, measured as trolox equivalent antioxidant capacity appeared significantly decreased by 14%. Serum levels of vitamin E were inversely correlated with ferritin (r = -.45; P = .003), suggesting a major consumption of this antioxidant under iron overload. Nontransferrin bound iron (NTBI) was in the range 4.5 to 54.8 micrograms/dL (mean, 21.8 +/- 13.9). Although NTBI had a positive trend with ferritin (r = .37, P = .03), no clear correlation was found with either MDA or vitamin E. A mild to severe hepatic damage, as assessed by serum transaminases, was shown in 24 of 42 patients. Serum levels of vitamin E (r = -.49, P = .015), vitamin A (r = -.48, P = .016) and lycopene (r = -.47, P = .020), were inversely correlated with the levels of transminases. On the other hand, lipid-soluble antioxidants in thalassemia patients were depleted to the same extent in hepatitis C virus (HCV)-infected (31 subjects) and in HCV-uninfected (10 subjects), while in the normal range in serum from 30 nonthalassemic patients with HCV-related chronic hepatitis. These results point out that the iron-induced liver damage in thalassemia may play a major role in the depletion of lipid-soluble antioxidants. The variations of the parameters evaluated in the present study were not correlated with the age of the patients. Our results suggest that the measurement of peroxidation products, matched with evaluation of antioxidants, may be a simple measure of iron toxicity in thalessemia, in addition to the conventional indices of iron status.

Abstract
The leucocyte adhesion molecules (beta 2 integrins) comprise CD11 alpha-chains and a common beta-chain (CD18). CD11a (leucocyte function-associated antigen 1, LFA-1) is expressed by most T cells, and is involved in antigen presentation by macrophages via its counter-receptor, intercellular adhesion molecule (ICAM-1, CD54). By criteria of double-label immunofluorescence of cryostat tissue sections, virtually all lamina propria T cells of the normal small bowel were found to express LFA-1 strongly. By contrast, only 30-60% of intra-epithelial lymphocytes (IEL) expressed detectable LFA-1, most of which were LFA-1 weak and CD18-. ICAM-1 was expressed strongly only by vascular endothelium. In coeliac disease, there was a modest increase of diffuse ICAM-1 expression in the lamina propria, mainly in the subepithelial zone, where ICAM-1+ macrophages were occasionally seen. There was also a slight overall increase in CD11a expression by IEL, seen predominantly in surface epithelium and mainly by the CD4+ minority subset, but not by CD4-CD8- (TcR gamma delta +) cells. These data suggest that the LFA-1/ICAM-1-dependent antigen presentation pathway is of minor importance to IEL in the normal small bowel, and does not assume a major role in coeliac disease.

Abstract
T cells expressing the gamma delta heterodimer of the T cell receptor (TCR) were studied with respect to their occurrence and expression of gamma delta TCR variable region (V) genes in the normal gastrointestinal mucosa and in a variety of inflammatory conditions. In controls, gamma delta TCR+ cells were a minority population confined to the epithelial compartment of stomach, small bowel and colonic mucosae. Unlike in the periphery, gastro-intestinal gamma delta TCR+ intraepithelial lymphocytes (IEL) were mainly V delta 1+ (89.98 +/- 17.70%); few were V delta 2+ (6.04 +/- 13.8%) or V gamma 9+ (11.38 +/- 10.73%). All gamma delta TCR+ IEL were CD5low; nearly half were CD8+ and the remainder were CD4-CD8- 'double negatives'. There was no significant change from normal in percentages of gamma delta TCR+ IEL in H. pylori-associated gastritis, Crohn's disease and ulcerative colitis. However, in coeliac disease, gamma delta TCR+ IEL were elevated from 2.54% (+/- 1.71) in controls to 29.6% (+/- 16.1) in untreated patients (P less than 0.001) and 18.5% (+/- 7.2) in treated patients (P less than 0.001) and more were CD4-CD8-. Otherwise, gamma delta TCR+ IEL phenotypes were little changed: the majority remained V delta 1+V delta 2-V gamma 9- and all were CD5low. These data suggest that increased gamma delta TCR+ IEL are not a generalized response to intestinal inflammation or to stress proteins, although the typical V delta 1+V delta 2-V gamma 9- CD5low phenotype is retained.

Abstract
Virus-specific T-cell responses are believed to be involved in the pathogenesis of liver cell injury secondary to hepatitis B virus infection. In this study, liver biopsy specimens from patients with chronic hepatitis B virus infection were analyzed for expression of two major pathways of adhesion used by cytotoxic T cells to interact with target cells. The lymphocyte function-associated antigen 3 was found preferentially expressed on hepatocytes of patients with active hepatitis B virus replication, whereas the expression of the intercellular adhesion molecule 1 on hepatocytes seemed more closely related with inflammatory activity. Adhesion molecules were also highly expressed on T lymphocytes found in areas of piecemeal and spotty necrosis, indicating the presence of antigen-specific "memory" T cells at the site of hepatocellular injury. This study suggests that the expression of the lymphocyte function-associated antigen 3 on hepatocytes may be important for viral elimination. The coordinate expression of the intercellular adhesion molecule 1 may regulate inflammatory response and enhance viral antigen presentation to T cells. Conversely, the absence of hepatocyte adhesion molecules might be a favorable factor for viral persistence.

Abstract
Leukocyte adhesion molecules are important in cell-cell interactions of the immune system. Lymphocyte function-associated antigen 1 (cluster designation 11a) mediates interactions between T cells and mononuclear phagocytes through its ligand, the intercellular adhesion molecule 1 (CD54), whereas complement receptors 3 (CD 11b) and 4 (CD11c) are involved in complement-mediated phagocytosis. Expression of CD11 molecules and intercellular adhesion molecule 1 was studied in colonic biopsy specimens from 20 patients with inflammatory bowel disease and 10 normal controls. In normal colon, few mononuclear phagocytes expressed lymphocyte function-associated antigen 1 and intercellular adhesion molecule 1 at high densities. The major adhesion molecule was CD11c. Thus, the largest population of normal colonic mononuclear phagocytes was represented by quiescent, resident macrophages with likely phagocytic function. In inflammatory bowel disease, mononuclear phagocytes showed only a slight increase in CD11a expression and no significant change in expression of CD11b and CD11c. By contrast, the percentage of mononuclear phagocytes expressing intercellular adhesion molecule 1 was increased from 6.9% +/- 3.9% in controls to 69.2% +/- 12.8% in ulcerative colitis (P less than 0.001) and to 45.7% +/- 22.8% in Crohn's disease (P less than 0.01), showing a close relationship with histological activity. The increased expression of intercellular adhesion molecule 1 in inflammatory bowel disease indicates a state of immunological activation induced by local release of inflammatory cytokines. Such induction of intercellular adhesion molecule 1 on mononuclear phagocytes may be important in the maintenance of chronic inflammation by facilitating interactions with T cells and T-cell antigen recognition.

Abstract
The behavior of tumor-associated trypsin inhibitor (TATI) as a marker for gynecological cancer was studied in a control population and in patients with different benign and malignant diseases. When a cut-off level of 21.4 micrograms/l was used the specificity was 100% in patients with benign diseases. The sensitivity in patients with malignant tumors was low for cervical and corpus cancer, 13% and 14%, respectively, whereas it was 33% in all the ovarian malignant tumors, reaching 60% in the mucinous type. There was a clear correlation between TATI level and stage.
