Abstract
With a global population of eight billion people, improving the sustainability and nutritional quality of diets has become critical. Mushrooms offer a promising solution because of their nutritional value and ability to be grown from agricultural residues, in line with the circular economy. This study, therefore, focuses on assessing the environmental compatibility of Agaricus bisporus mushroom production in Italy, the world's third largest per capita consumer, by using a Life Cycle Assessment (LCA) and an integrated Water-Energy-Nitrogen-Carbon-Food (WENCF) nexus analysis. The LCA results reveal that for a functional unit of 23,000 kg of the substrate, the production process emits 2.55 × 104 kg of CO2 eq. Sensitivity analysis shows that changing input quantities can reduce environmental impacts by about 5 %. In addition, one scenario evaluates the environmental effects of recycling resources by introducing water and ammonium sulfate from scratch instead of continuous recycling, along with water purification. The study shows that sustainable food production can mitigate resource depletion, climate-altering emissions, and intersectoral competition. Using agro residues for mushroom cultivation and optimizing resource management contribute to environmental sustainability. This approach could not only improve the resilience and efficiency of the food system but could also improve the sustainability of diets. In conclusion, this study highlights the importance of adopting sustainable and circular approaches in mushroom production to address global challenges related to food sustainability.

Abstract
Detailed molecular composition of solid phase extracted dissolved organic matter (SPEDOM) collected from fractured-rock groundwater was compared to connected surface river water at two different watersheds in the unconfined chalk aquifer of Champagne in France using full scan ultrahigh resolution electrospray and photoionization Fourier transform ion cyclotron mass spectrometry (FT-ICR MS), Orbitrap tandem MS (MS/MS) and 1H magnetic resonance spectroscopy (NMR). 1H NMR spectroscopy indicated that groundwater SPEDOM carried a higher contribution of aliphatic compounds while surface river waters SPEDOM were enriched in carboxyl-rich alicyclic molecules (CRAM), acetate derivatives and oxygenated units. Furthermore, we show here that use of photoionization (APPI(+)) in aquifer studies is key, ionizing about eight times more compounds than ESI in surface river water samples, specifically targeting the dissolved organic nitrogen pool, accounting for more than 50% of the total molecular space, as well as a non-polar, more aromatic fraction; with little overlap with compounds detected by ESI(-) FT-ICR MS. On the other hand, groundwater SPEDOM samples did not show similar selectivity as less molecular diversity was observed in APPI compared to ESI. Mass-difference transformation networks (MDiNs) applied to ESI(-) and APPI(+) FT-ICR MS datasets provided an overview of the biogeochemical relationships within the aquifer, revealing chemical diversity and microbial/abiotic reactions. Finally, the combination of ESI(-) FT-ICR MS and detailed Orbitrap MS/MS analysis revealed a pool of polar, anthropogenic sulfur-containing surfactants in the groundwaters, likely originating from agricultural runoff. Overall, our study shows that in this aquifer, groundwater SPEDOM contains a significantly reduced pool of organic compounds compared to surface river waters, possibly related to a combination of lack of sunlight and adsorption of high O/C formulas to mineral surfaces.

Abstract
Prehistoric monuments often constitute evident landmarks and sometimes, after falling into disuse, fascinated local people enough to stimulate speculations about their origin over time. According to legend, the Hill of Udine (NE Italy) was built by Attila the Hun's soldiers, but its origin (natural or anthropogenic) has been debated until now. Our research analyzed five new 40-m long stratigraphic cores, investigating for the first time the total thickness of the hill and compared the data with the available archaeological information. Moreover, we considered other hills and mounds in northern Italy and other European regions where folklore traditions relate their origin to Attila. The geoarchaeological and ethnographic data prove that the Hill of Udine is a Bronze Age anthropogenic mound erected between 1400 and 1150 BCE and that, later, folklore has transformed the ancestral memory of its origin into legend. By measuring 30 m in height and over 400,000 m3 in volume, the flat-topped hill is the largest prehistoric mound in Europe. This discovery reveals unprecedented skills in earth construction and confirms significant anthropogenic modifications of the environment during Bronze Age.

Abstract
Renal ectopia and fusion anomalies are Congenital Anomalies of the Kidney and the Urinary Tract (CAKUT) that are usually incidentally detected and asymptomatic. Patients affected present a higher risk of complications like recurrent urinary tract infections or obstruction. Pancake kidney (PK) is one of the rarest types of renal anomaly with complete fusion of the superior, mild and inferior poles of both kidneys in the pelvic cavity. Each kidney has its own excretory system with two ureters that do not cross the midline. In the asymptomatic cases, a conservative approach should be performed. Surgical management may be needed when urological problems occur. PK is often associated with congenital anomalies of other organs. Ultrasound is the first line radiological examination for the diagnosis and the follow-up of kidney malformations. The main sonographic findings suggesting PK diagnosis are a large and lobulated renal mass consisting of two fused lateral lobes without an intervening septum located in the pelvic cavity. Each lobe usually has a separate pelvicalyceal system, the renal pelvis is anteriorly placed and the ureters are usually short and enter the bladder normally without crosses the midline. Ultrasonography gives useful information on the morphology and volume of the organ, and on its vascularization through the use of the Color- and Power-Doppler. Computer Tomography and Magnetic Resonance Urography are second level techniques used to confirm the diagnosis and to evaluate the presence of other abnormalities. The knowledge of the imaging findings and the anatomy of congenital renal malformations is important to avoid diagnostic pitfalls and misinterpretations. We report the case of a 14-years old female with PK who was misdiagnosed with a horseshoe kidney (HSK) during an abdominal ultrasound.

Abstract
Langerhans cell histiocytosis (LCH) is a rare disease of the myeloid precursor cells, it predominantly occurs in the skull and long bones as unifocal bone lesions. Aneurysmal bone cysts (ABC) are benign, expansive and lytic bone. Reports of secondary ABC occurring in LCH are rare, having only been reported twice in the skull. Here, we report the first case of LCH masquerading as ABC in a 14-month-old female child who presented with a rapidly growing mass in her left femur. The lesion had typical radiological features of ABC, and only histological examination revealed the presence of cells suggestive of LCH.

Abstract
Objective Preterm birth is associated with altered angiogenesis and with increased risk of cardiovascular dysfunction and hypertension at adulthood. We previously demonstrated that in preterm newborns circulating cord blood endothelial progenitor cells (ECFC), responsible for angio/vasculogenesis, are reduced in number and display altered angiogenic properties. Altered angiogenic function was associated with a decreased expression of pro-angiogenic genes, among which the AMOT gene which is a strong positive regulator of angiogenesis. Such dysregulation may be related to epigenetic factors. In this study we analyse the methylation profiling of the AMOT gene during development, through a comparative analysis of the cord blood ECFC of preterm newborns and their term counterpart. Methods We used both cloning-sequencing and pyrosequencing experiments to perform a comparative analysis of the DNA methylation profile of the promoter CpG island of AMOT gene in the cord blood ECFC of 16 preterm newborns (28–35 weeks gestational age-GA) and 15 term newborns (>37 weeks GA). Results Twenty nine clones (obtained from 2 term newborns) and forty clones (obtained from 3 preterm newborns) were sequenced. The AMOT gene methylation rate was significantly higher in preterm compared to term newborns (4.5% versus 2.5% respectively: χ2 = 3.84; P = 1.8 10−02). Bisulfite pyrosequencing identified four CpG dinucleotides with significantly higher methylation levels in preterm newborns. This CpG-targeted methylation significantly decreased with increasing gestational age. Conclusions These findings highlight importance of pro-angiogenic AMOT gene methylation in ECFC, suggesting that epigenetic mechanisms may control the regulation of angiogenesis during development. Therefore they pave the way to specific short term and long term complications of preterm birth by altered angiogenesis.

Abstract
Enzymes are specific biological catalysts able to react under mild conditions of temperature and pH and their use in food industry for bioremediation is well known. Research in recent years has been intense, much of it elicited by the great number of different exploitable enzymes. Employment of enzymes in many bioremediation processes is made in order to protect the environment from damage caused by industrial polluting effluents. In particular, the food industry is one of the most important sectors among the manufacturing industries as far as production values are concerned; indeed, food industry processes involve large amounts of water and contribute to pollution loads discharged into water resources. In particular the presence of phenols in agroindustrial effluents has attracted interest for laccases and tyrosinases use in wastewater treatment and bioremediation. The presence of phenolic compounds in drinking and irrigation water or in cultivated land represents a significant health and/or environmental hazard and, therefore, the development of methods for their removal and transformation have received increased attention in recent years. The main purpose of this paper was to present the most recent results dealing with the fundamental and applied aspects of free and immobilised polyphenoloxidases for food industry wastewater processing.

Abstract
The current study aimed to identify and validate an applicable immunohistochemistry panel including Ki-67, c-MYC, estrogen receptor-α (ER-α), and progesterone receptor isoforms A/B (PR-A/B) in correlation with clinicopathological parameters in patients affected by deep infiltrating endometriosis. Tissue microarrays were prepared from a cohort of 113 patients. Phenotypic profile of the panel molecules was evaluated in glands and stroma in parallel with microvessels and stroma density measurements. Principal component analysis was performed on 8 immunohistochemical variables, 2 histological variables, and 8 subgroups of clinical parameters. The immunohistochemical profiling showed consistent Ki-67 immunostaining in 17.9% of the samples and c-MYC in 83.1%, while intense ER-α immunoreactivity was detected in 84% of the samples and PR-A/B isoforms in 24.1% of them. The combination of clinical parameters and tissue phenotype allowed a stratification of endometriosis-affected patients. Such novel phenotypical and clinical correlation could be helpful in the future studies for a better stratification of the disease aiming at a personalized patient care.

Abstract
Several lines of evidence indicate that endometriosis could be partially due to selective epigenetic deregulations. Promoter hypermethylation of some key genes, such as progesterone receptor and aromatase, has been associated with the silencing of these genes and might contribute to the disease. However, it is unknown whether global alterations in DNA methylation patterns occur in endometriosis and to what extent they are involved in its pathogenesis. We conducted a whole-genome scanning of methylation status in more than 25,000 promoters, using methylated DNA immunoprecipitation with hybridization to promoter microarrays. We detailed the methylation profiles for each subtype of the disease (superficial endometriosis, endometriomas, and deep infiltrating endometriosis) and compared them with the profile obtained for the eutopic endometrium. In line with the current theory of the endometrial origin of endometriosis, the overall methylation profile was highly similar between the endometrium and the lesions. It showed promoter regions consistently hypomethylated or hypermethylated (more than 1.5-times, as compared with endometrium) and others specific to one given subtype. Albeit there was no systematic correlation between promoter methylation and expression of nearby genes, 35 genes had both methylation and expressional alterations in the lesions. These genes, reported here for the first time, might be of interest in the development of endometriosis. In addition, hypermethylated regions were located at the ends of the chromosomes, whereas hypomethylated regions were randomly distributed all along the chromosomes. We postulated that this original observation might participate to the chromosomal stability and protect the endometriotic lesion against malignancy.

Abstract
Background It is known that primary sequences of enzymes involved in sterol biosynthesis are well conserved in organisms that produce sterols de novo. However, we provide evidence for a preservation of the corresponding genes in two animals unable to synthesize cholesterol (auxotrophs): Drosophila melanogaster and Caenorhabditis elegans. Principal Findings We have been able to detect bona fide orthologs of several ERG genes in both organisms using a series of complementary approaches. We have detected strong sequence divergence between the orthologs of the nematode and of the fruitfly; they are also very divergent with respect to the orthologs in organisms able to synthesize sterols de novo (prototrophs). Interestingly, the orthologs in both the nematode and the fruitfly are still under selective pressure. It is possible that these genes, which are not involved in cholesterol synthesis anymore, have been recruited to perform different new functions. We propose a more parsimonious way to explain their accelerated evolution and subsequent stabilization. The products of ERG genes in prototrophs might be involved in several biological roles, in addition to sterol synthesis. In the case of the nematode and the fruitfly, the relevant genes would have lost their ancestral function in cholesterogenesis but would have retained the other function(s), which keep them under pressure. Conclusions By exploiting microarray data we have noticed a strong expressional correlation between the orthologs of ERG24 and ERG25 in D. melanogaster and genes encoding factors involved in intracellular protein trafficking and folding and with Start1 involved in ecdysteroid synthesis. These potential functional connections are worth being explored not only in Drosophila, but also in Caenorhabditis as well as in sterol prototrophs.

Abstract
Premature ovarian failure (POF) is a common pathology leading to infertility affecting about 1% of women under 40 years old. In POF patients, the ovarian dysfunction is characterized by the lack of the ovarian response to close a negative feedback loop on the synthesis of pituitary gonadotropins. Although the majority of cases are considered as idiopathic, diverse aetiologies have been associated, including genetic factors. Up to now, the potential genetic causes of non-syndromic POF have been established mainly by genetic linkage analysis of familial cases or by the screening of mutations in candidate genes based on animal models. Here, we review recent advances in the study of candidate genes.

Abstract
CONTEXT We report herein a remarkable family in which the mother of a woman with 46,XY complete gonadal dysgenesis was found to have a 46,XY karyotype in peripheral lymphocytes, mosaicism in cultured skin fibroblasts (80% 46,XY and 20% 45,X) and a predominantly 46,XY karyotype in the ovary (93% 46,XY and 6% 45,X). PATIENTS A 46,XY mother who developed as a normal woman underwent spontaneous puberty, reached menarche, menstruated regularly, experienced two unassisted pregnancies, and gave birth to a 46,XY daughter with complete gonadal dysgenesis. RESULTS Evaluation of the Y chromosome in the daughter and both parents revealed that the daughter inherited her Y chromosome from her father. Molecular analysis of the genes SOX9, SF1, DMRT1, DMRT3, TSPYL, BPESC1, DHH, WNT4, SRY, and DAX1 revealed normal male coding sequences in both the mother and daughter. An extensive family pedigree across four generations revealed multiple other family members with ambiguous genitalia and infertility in both phenotypic males and females, and the mode of inheritance of the phenotype was strongly suggestive of X-linkage. CONCLUSIONS The range of phenotypes observed in this unique family suggests that there may be transmission of a mutation in a novel sex-determining gene or in a gene that predisposes to chromosomal mosaicism.

Abstract
Deletions of distal chromosome 9p24 are often associated with 46,XY gonadal dysgenesis and, depending on the extent of the deletion, the monosomy 9p syndrome. We have previously noted that some cases of 46,XY gonadal dysgenesis carry a 9p deletion and exhibit behavioural problems consistent with autistic spectrum disorder. These cases had a small terminal deletion of 9p with limited or no somatic anomalies that are characteristic of the monosomy 9p syndrome. Here, we present a new case of 46,XY partial gonadal dysgenesis and autistic spectrum disorder associated with a de novo deletion of 9p24 that was detected by ultra-high resolution oligo microarray comparative genomic hybridization. The deletion included the candidate sex-determining genes in the region DMRT1 and DMRT3. These data suggest that a gene responsible for autistic spectrum disorder is located within 9p24. It remains to be determined if the gonadal dysgenesis and autistic spectrum disorder are caused by a single gene or if they are caused by distinct genetic entities at 9p24.

Abstract
The main factor influencing the sex determination of an embryo is the genetic sex determined by the presence or absence of the Y chromosome. However, some individuals carry a Y chromosome but are phenotypically female (46,XY females) or have a female karyotype but are phenotypically male (46,XX males). 46,XX maleness is a rare sex reversal syndrome affecting 1 in 20,000 newborn males. Molecular analysis of sex-reversed patients led to the discovery of the SRY gene (sex-determining region on Y). The presence of SRY causes the bipotential gonad to develop into a testis. The majority of 46, SRY-positive XX males have normal genitalia; in contrast SRY-negative XX males usually have genital ambiguity. A small number of SRY-positive XX males also present with ambiguous genitalia. Phenotypic variability observed in 46,XX sex reversed patients cannot be explained only by the presence or absence of SRY despite the fact that SRY is considered to be the major regulatory factor for testis determination. There must be some other genes either in the Y or other autosomal chromosomes involved in the definition of phenotype. In this article, we evaluate four patients with 46,XX male syndrome with various phenotypes. Two of these cases are among the first reported to be diagnosed prenatally.

Abstract
Deletions of the Y chromosome are a significant cause of spermatogenic failure. Three major deletion intervals have been defined and termed AZFa, AZFb and AZFc. Here, we report an unusual case of a proximal AZFb deletion that includes the Y chromosome palindromic sequence P4 and a novel heat shock factor (HSFY). This deletion neither include the genes EIF1AY, RPS4Y2 nor copies of the RBMY1 genes. The individual presented with idiopathic azoospermia. We propose that deletions of the testis-specific HSFY gene family may be a cause of unexplained cases of idiopathic male infertility. This deletion would not have been detected using current protocols for Y chromosome microdeletion screens, therefore we recommend that current screening protocols be extended to include this region and other palindrome sequences that contain genes expressed specifically in the testis.

Abstract
Anorchia, or the "vanishing testis syndrome," is characterized by the absence of testis in a 46,XY individual with a male phenotype. The etiology is unknown; however, the familial occurrence of the disease and the association of this phenotype with 46,XY gonadal dysgenesis has led to the suggestion that genetic factors, which play a role in testicular determination, may be involved. Alternatively, exploratory laparoscopy has suggested that anorchia may be caused by a prenatal testicular vascular accident associated with torsion during testicular descent. We screened a cohort of 14 boys with bilateral anorchia for mutations in the Y chromosome-linked testis-determining gene SRY (sex-determining region, Y chromosome); in the gene necessary for correct testicular descent, INSL3; and in the gene of its receptor (LGR8). Mutations in the INSL3 gene and the LGR8 T222P mutation are known to cause cryptorchidism. We confirmed previous reports that mutations in the SRY gene are not associated with anorchia. Although a common polymorphism was identified in the INSL3 gene, no mutations were observed. The recurrent T222P mutation in the LGR8 gene was not found in any of the patients. These data show for the first time a lack of association between genetic factors necessary for correct testicular descent and anorchia.

Abstract
Activation of the classical complement pathway is crucially involved in complement-mediated endothelial cell damage in ischemia-reperfusion injury. C1 inhibitor is the only known physiological inhibitor of classical complement pathway activation. Transgenic mice overexpressing human C1 inhibitor were used in a surgical lower torso and a liver ischemia-reperfusion model. Organ-specific endothelial disruption was determined by 125I-tagged albumin extravasation. In the lower torso ischemia-reperfusion model, transgenic mice overexpressing the C1 inhibitor were protected in the muscle and the lungs from endothelial cell damage. In the liver ischemia-reperfusion model, endothelial cell integrity was preserved in transgenic animals in the liver, the gut and the lungs. Our data indicate that inhibiting complement activation by a transgenic approach is effective in protection against ischemia-reperfusion injury.

Abstract
Here we report a rare case of septic spondilodiskitis by methicillin-resistant Staphylococcus aureus, complicated by the atypical involvement of two articular sites such as manubrio-clavicular joints and right wrist. The source of the septic process was identified in hand's eczematous lesions and paronychia. A first therapeutical attempt performed by combining teicoplanin with netilmicin or rifampicin was useless. A new course with vancomycin instead of teicoplanin favoured the prompt remission of symptoms. Following 10 weeks of continuous treatment, we observed the complete disappearance of all radiological signs of vertebral damage. Though rarely, polyarthritis may complicate a Staphylococcus aureus bacteraemia. An adequate chemio-antibiotic course may lead to definitive recovery and avoid surgery.

Abstract
We have produced transgenic mice expressing human C1 inhibitor mRNA and protein under the control of the human promoter and regulatory elements. The transgene was generated using a minigene construct in which most of the human C1 inhibitor gene (C1NH) was replaced by C1 inhibitor cDNA. The construct retained the promoter region extending 1.18 kb upstream of the transcription start site, introns 1 and 2 as well as a stretch of 2.5 kb downstream of the polyadenylation site, and therefore carried all known elements involved in transcriptional regulation of the C1NH gene. Mice with high serum levels of human C1 inhibitor, resulting from multiple tandem integrations of the C1 inhibitor transgene, were selected. Immunohistochemistry in combination with in situ hybridization was applied to localize the sites of C1 inhibitor biosynthesis and to demonstrate its local production in brain, spleen, liver, heart, kidney, and lung. The distribution of human C1 inhibitor-expressing cells was qualitatively indistinguishable from that of its mouse counterpart, but expression levels of the transgene were significantly higher. In the spleen, production of C1 inhibitor was colocalized with that of a specific marker for white pulp follicular dendritic cells. This study demonstrates a stringently regulated expression of both the endogenous and the transgenic human C1 inhibitor gene and reveals local biosynthesis of C1 inhibitor at multiple sites in which the components of the macromolecular C1 complex are also produced.

Abstract
BACKGROUND AND OBJECTIVES To determine the clinical activity and safety of the combination immunotherapy of the chimeric anti-CD20 antibody, Rituximab, and Interferon (IFN)- alpha 2a DESIGN AND METHODS Sixty-four patients with relapsed low-grade or follicular B-cell non Hodgkin's lymphoma received 4 infusion of Rituximab (375 mg/m(2) x dose) after priming and simultaneous treatment with IFN- alpha 2a. RESULTS The overall response rate was 70% with 33% complete responses. Median for duration of response is 19 months, after a median follow-up of 22 months. By univariate analysis none of the most common prognostic factors predicted for response to therapy. After treatment 10 patients become bcl-2 negative in the bone marrow, but no correlation between molecular and clinical response was found. Fifty-three patients (83%) had drug related or unknown origin adverse events. The number of adverse events per patient varied from 1 to 21. Considering all 272 events, 231 (85%) were grade 1 or 2, 36 (13%) grade 3 and 5 (2%) grade 4. Twenty-three patients required reduction in the dose and/or short discontinuation of IFN treatment, either during priming or subsequent treatment. The most frequent adverse events were leukopenia, fever, neutropenia, hypotension and thrombocytopenia. INTERPRETATION AND CONCLUSIONS this report shows that combination immunotherapy Rituximab + IFN- alpha 2a is active and relatively well tolerated. The overall response rate of 70% and the median duration remission of 19 months compare favorable with the results obtained with Rituximab alone in similar subset of patients. Randomized trials, investigating Rituximab versus combination immunotherapy are needed.

Abstract
In 1985, Stein et al demonstrated the expression of the lymphoid activation antigen CD30/Ki by neoplastic cells. Fifteen years after the first description, anaplastic large-cell lymphomas (ALCL) are now thought to be a heterogeneous group in terms of their clinical, morphologic, phenotypic, cytogenetic, and molecular biology features. However, on the basis of a specific genetic anomaly and expression of a chimeric nucleophosmin anaplastic lymphoma kinase (NPM-ALK) protein and its variants, a distinct clinicopathologic entity defined as "ALK-positive lymphoma" or "ALKoma" can be recognized. Based on molecular and clinical criteria, 3 entities of primary ALCL can be identified: primary systemic ALK positive, primary systemic ALK negative, and primary cutaneous ALCL. This review focuses on advances in the knowledge of primary systemic ALCL biology and discusses therapeutic approaches based on ALK expression. The presence of this protein appears to be an important prognostic factor and, combined with an age-adjusted International Prognostic Index, could allow researchers to design more specific clinical trials aimed at finding new, more efficacious and less toxic treatments.

Abstract
Rituximab is a chimeric anti CD-20 monoclonal antibody containing human IgG1 kappa constant regions, with murine variable regions. The anti-lymphoma effects of Rituximab are probably due to complement and antibody-dependent cell-mediated cytotoxicity, and induction of apoptosis. Phase II trials have demonstrated a strong activity of rituximab alone in indolent B non-Hodgkin lymphoma, especially in patients with follicular lymphoma. The most utilized dose-schedule is 375 mg/m(2) weekly x 4. The association with chemotherapy or with interferon-alpha increases Rituximab efficacy. More recently, Rituximab have showed activity also in diffuse large cell lymphoma, mantle cell lymphoma and in other B-malignancies. Good results have also been obtained utilizing Rituximab for in vivo purging. However, we are still far from having found a definite position for Rituximab in the treatment of lymphoproliferative disorders. The aim of future studies should be to develop new strategies that will hopefully produce the most effective Rituximab-based regimens in order to find the Rituximab key position in the treatment of B-malignancies

Abstract
BACKGROUND AND OBJECTIVE Diagnostic criteria for essential thrombocythemia (ET) remain essentially negative, that is, exclusion of other myeloproliferative diseases and causes of reactive thrombocytosis. A platelet count above 600x10(9)/L is still generally considered an absolute diagnostic criterion although new protocols for positive diagnostic criteria have recently been proposed, reducing the stringency of a definite platelet limit. This study demonstrates that a platelet count 600x10(9)/L is not a reliable diagnostic criterion for ET, especially in the early stages. DESIGN AND METHODS An ongoing retrospective study by the GIMMC analyzed 2,316 ET patients diagnosed between 1986 and 1995. Of these 2,316 patients, diagnosed according to the PVSG criteria, 68 had a platelet count 600x10(9)/L and were analyzed separately; 37 out of 68 were excluded from this analysis because of a follow-up shorter than 2 years and/or because of treatment with myelosuppressive agents. The remaining 31 patients were the subjects of our study. RESULTS After a median follow-up of 4.56 years (range 2-9.6 years) none of the 31 patients had a spontaneous decrease of platelets to the normal range. Transformation to a different chronic myeloproliferative disorders was never observed and no patient developed a condition known to produce reactive thrombocytosis. During follow-up, 23 patients (74%) were treated with anti-aggregating drugs, mainly aspirin. The disease did not evolve into acute leukemia in any patient, 1 had a thrombotic event and none presented hemorrhagic episodes. Median platelet count during follow-up was 534x10(9)/L (range 398-997x10(9)/L). INTERPRETATION AND CONCLUSIONS Long term follow-up has documented that our 31 patients were correctly diagnosed as having ET, although platelet count was 600x10(9)/L. Our patients were probably in a early phase of their disease and following updated PVSG criteria would have been misdiagnosed leading to incomplete recognition of the natural history of the disease. Further, because an early diagnosis could also have a clinical relevance, our results outline the need for new criteria for the diagnosis of ET. The exclusion of patients with a platelet count between 400 and 600x10(9)/L may prevent patients, nevertheless at risk of vascular complications, from being treated.

Abstract
Hepatitis G virus (HGV) is a parenterally transmitted virus, frequently associated with hepatitis C virus infection. Hepatitis G virus RNA was detected by reverse transcription-polymerase chain reaction in the serum of 40 patients with chronic hepatitis C. Nine (22.5%) patients had evidence of hepatitis G virus viraemia. No significant epidemiological or virological differences could be demonstrated between subjects infected with both hepatitis G virus and hepatitis C virus and subjects infected with hepatitis C virus alone. Aminotransferase values were comparable between the two groups, whereas higher levels of cholestatic enzymes (P< 0.001) were reported in the hepatitis G virus/hepatitis C virus-positive patients. A liver biopsy was performed on all 40 patients no later than 6 months before recruitment. The mean histological activity index did not differ between hepatitis G virus-positive and hepatitis G virus-negative patients, whereas specific histological features such as macrovesicular steatosis, portal granulomas, and bile duct damage were more commonly observed among the coinfected patients. The results indicate that coinfection with hepatitis G virus probably does not have a significant effect on hepatitis C virus-induced hepatic damage.

Abstract
The gene encoding C1 inhibitor, the major control element of activation of the classical pathway of complement and a major inhibitor of several plasma serine proteases, has been studied only in man, where deficiency of C1 inhibitor results in the dominantly transmitted disease hereditary angioedema. Full-length mouse C1 inhibitor cDNA and genomic clones were isolated and characterized as a first step towards the complete characterization of the pattern of C1 inhibitor expression and the production of an animal model of C1 inhibitor deficiency. Restriction-enzyme and sequence analyses of a full-length genomic clone demonstrated that the mouse gene has the same structure as the human homologue, but differs in size (9 kb versus 17 kb), mostly due to the presence of repetitive Alu elements in the human gene. Sequence comparisons in the promoter region indicate important similarities, i.e. the absence of a TATA box, the presence of an initiator sequence encompassing the transcription-start site and of a gamma-interferon-activated sequence (GAS) element at position -124 of the human sequence. A stretch of about 100 nucleotides in intron 1 reveals an unusually high degree of conservation for non-coding sequences and contains non-canonical but conserved tandemly arranged GAS elements at positions 369 and 388 of the human sequence. This finding supports the conclusions of functional studies on the human C1INH gene indicating a role of this region in modulation of transcription by interferons. The profile of C1 inhibitor expression in mouse liver, lung, heart, kidney, spleen and brain was determined by quantitative northern blot analysis.

Abstract
The efficacy of alfa-interferon (alfa-IFN) in essential thrombocythemia (ET) patients has been reported by several authors. The aim of this study is to assess the magnitude of the effect of alfa-IFN on the neoplastic clone. As of December 1993, 11 ET patients received alfa-IFN at a dose of 3-6 MU/s.c./day for 6 months. Ten of 11 obtained complete hematological remission (CHR) and one achieved partial hematological remission. Megakaryocyte concentration was reduced in six cases. The spleen,which was enlarged in four patients, decreased in size in two patients. Seven of eight patients who were symptomatic at diagnosis obtained resolution of symptoms. In order to obtain indications about the structural modifications induced by alfa-IFN in ET megakaryocytes (Mks), Fourier-transform infra-red microspectroscopy analysis performed on 10 single Mks of each patient, was done in seven of 11 patients; the analysis showed a reduction of A1/A2 ratios (A1 integrated area of the band at 1080 cm(-1) due to the nucleic acids absorption; A2 integrated area of the band at 1540 cm(-1) due to proteic components absorption) in five cases, and in three of these five patients A1/A2 ratios achieved normal values. After alfa-IFN treatment we did not observe any change in the methylation pattern of DNA from the granulocyte fraction. Our results confirm the efficacy of alfa-IFN in ET patients, and the decrease of A1/A2 ratios in several patients is a demonstration of the depth of the effect of alfa-IFN on the neoplastic clone. The results of clonality studies showed the persistence of clonal hematopoiesis. Whether higher alfa-IFN dose and/or more prolonged alfa-IFN therapy may allow a restoration of polyclonal hematopoiesis remains to be determined and should be explored in future clinical trials.

Abstract
The aim of the present study was to evaluate the sensitivity and specificity of the ultrasonography, in comparison with other methods of investigation (scintigraphy, sialography, and biopsy), in scanning morphostructural changes in the parotid gland in patient with Sjögren's syndrome. During the period June-October 1994, 34 patients (5 males and 29 females, age ranged between 20 and 88 years) with "sicca syndrome" underwent to echography, scintigraphy, sialography and biopsy. The diagnosis was confirmed or excluded using the European Community Epidemiologic Committee criteria for Sjögren's syndrome. Twenty-two patients out of 34 were affected by Sjögren's syndrome, while the others resulted as control subjects. The ultrasonographic investigation has shown 76.19% of sensitivity and 30.43% of specificity. Even if echography is a non-invasive method, which could be used as preliminary approach for studying the diffused involvement of the parotid gland, at the status of the art, it is not completely reliable for the global evaluation of the morphostructural changes in patients with Sjögren's syndrome, in comparison with the other techniques. Because of the double nature of the gland injury, it appears to be essential the diagnostic integration between echography and sialography.

Abstract
We obtained a cell line (So1) from a patient who rejected a T-depleted allogeneic BMT. Cytotoxic activity by cell-mediated lympholysis was found using So1 as effector and EBV-transformed donor B cells as targets, but no lysis of the patient's pretransplantation cells and of an unrelated HLA-nonidentical subject was observed, suggesting it was related to recognition of a minor transplantation antigen which could have contributed to rejection of the graft. To define the HLA-restricting element(s), cell-mediated lympholysis experiments were performed with several B cell lines as targets. So1 lysed only targets sharing an HLA-B44 antigen with the patient, thus demonstrating that the minor transplantation antigen recognized was restricted by HLA-B44. The absence of lysis against the patient's pretransplantation cells may be related to the absence of the minor antigen, suggesting that the patient's cytotoxic lymphocytes able to recognize a minor transplantation antigen on the donor cells contributed to the rejection of the HLA-identical graft. Mendelian segregation of this minor antigen was found in familial studies. Lysis was observed with cells from members of 2 families who had an association of HLA-B44 antigen in the haplotype and the minor antigen, whereas in 2 other HLA-B44-positive families, no lysis was found, probably because this minor antigen was absent. Furthermore, these family studies: (1) demonstrated that this minor antigen segregates with the MHC, suggesting its localization on chromosome 6; and (2) showed a close relationship between the minor antigen and HLA-B44, strongly suggesting a linkage disequilibrium between the minor antigen and its restriction antigen B44.

Abstract
To determine the validity of ultrasonic nebulization of distilled water (UNDW, "fog") in comparison with methacholine challenge, in the assessment of toluene diisocyanate (TDI) asthma, we evaluated 75 subjects exposed to TDI with work-related respiratory symptoms. Subjects were submitted to bronchial challenge with methacholine at first, thereafter to UNDW inhalation and to specific challenge with TDI. The diagnosis of TDI-asthma was made in 30 of 75 patients (40 percent) who developed a bronchoconstrictive response to the specific challenge (reactors). Sensitivity and specificity of UNDW alone, methacholine alone, and of the combination of the two tests were determined with the results of the specific challenge with TDI as the "gold standard." Both frequency and severity of bronchoconstrictive response to UNDW (FEV1 decrease > or = 15 percent) and the degree (PD15 FEV1) and frequency of bronchial hyperresponsiveness to methacholine were significantly higher in TDI reactors than in nonreactors. The UNDW had higher specificity (82.2 percent vs 51.1 percent) but lower sensitivity (40 percent vs 76.7 percent) than methacholine. The combination in parallel (positivity of any of the two challenges) of methacholine and UNDW challenge did not change sensitivity to a great extent (80 percent vs 76.7 percent), whereas combination in series (positivity of both challenges) had considerably greater specificity (86.7 percent vs 51.1 percent) than methacholine alone. We conclude that in the assessment of TDI-asthma, the validity of UNDW challenge alone is limited since it is insufficiently sensitive. Instead, combining UNDW and methacholine challenge when methacholine is positive improves our ability in identifying subjects with TDI-asthma diagnosed with the specific challenge. This procedure constitutes a first objective confirmation of a suggestive history of TDI-asthma that is useful for clinical purposes. However, especially for medicolegal purposes, the definitive diagnosis requires the specific challenge.

Abstract
To verify the efficacy and the tolerability of local immunotherapy (LI) by inhalation of a powder extract of house dust mite (HDM), in comparison with parenteral immunotherapy (PI) by injection, 10 patients with asthma due to HDM were studied in a blind fashion. 5 patients (Group A) underwent LI and subcutaneous injections of placebo, 5 patients (Group B) underwent PI and inhalation of lactose for 6 months. In both groups each inhalation was preceded by premedication with disodium cromoglycate (DSCG) (40 mg). In Group A a significant decrease in symptoms score and in peak expiratory flow (PEF)-derived parameters was observed already after 3 months of treatment, and 2 patients lost the late component of the bronchial response to the challenge with HDM. No significant variation was found in bronchial responsiveness to methacholine and ultrasonically nebulized distilled water (UNDW) and in immunologic humoral and cellular parameters in peripheral blood after treatment in either group. No local important adverse reactions were observed in Group A and no systemic side effects were observed in either group. We conclude that LI is as effective as PI, but more rapid in its action, in the treatment of asthma due to HDM. Moreover, LI is locally well tolerated, providing DSCG is inhaled before each therapeutic inhalation, and does not induce systemic side effects.

Abstract
Blood cells were obtained from patients selected for allogeneic bone marrow transplantation who had undergone a conditioning regimen (CR) with high-dose chemotherapy and total body irradiation. The majority of residual cells bore CD3 antigen (range: 68-98%), and the CD4/CD8 ratio was normal. The effect of these residual/radioresistant cells on donor bone marrow hematopoiesis was investigated in eleven cases. Growth of donor CFU-GM and BFU-E was inhibited by 22-65% and 29-77%, respectively, when donor marrow was cocultured with residual cells at various ratios. In contrast, blood cells obtained from two patients prior to CR had no inhibitory effect. Supernatants obtained following incubation of residual cells from 9 patients were able to inhibit the growth of CFU-GM and BFU-E from normal unrelated subjects, whereas supernatants obtained before CR and from cultured normal marrow had no inhibitory effect. In addition, in blocking experiments, an anti-TNF-alpha MoAb was able to prevent this inhibition. Thus, TBI might be able to select and/or activate cells responsible for hematopoietic growth inhibition by a mechanism involving, at least in part, TNF-alpha.

Abstract
We report the clinical findings and the results of inhalation challenge with toluene diisocyanate (TDI) and methacholine in 113 subjects with a history of exposure to TDI and work-related respiratory symptoms. Only some of the subjects (40.7%) had isocyanate asthma, diagnosed by a positive TDI inhalation challenge. Most reactors had a dual (30.4%) or a late (41.3%) response. The interval between the last occupational exposure and the specific challenge was significantly shorter in reactors, and among this group the number of immediate reactions to TDI decreased progressively with an increasing interval. The reactors had a significantly higher proportion of positive responses to methacholine and a significantly lower mean PD15 FEV-1 (provocative dose of methacholine which provoke a 15% decrease in forced expiratory volume in 1 second) (reactors: 557 micrograms, SEM 92.3; nonreactors: 1346 micrograms, SEM 128, P less than .01). Methacholine challenge could not identify subjects with isocyanate asthma.

Abstract
The physiological significance of autoreactive T cells derived from normal individuals and activated in the absence of any identifiable foreign antigen by class II MHC-syngeneic molecules remains unexplained. Here we report that autoreactive T-cell clones (Tilkin et al. 1987) proliferate and are able to kill autologous or syngeneic EBV-cell lines but not autologous or syngeneic HLA-Class II-positive PHA-activated T-cell blasts. Furthermore, they are able to efficiently inhibit in vitro the differentiation of CFU-GM and BFU-E colonies, in agreement with the well-known observation that hematopoietic precursors express HLA-DR molecules (Cannistra et al. 1986). The reasons why the autoreactive clones do not recognize T-cell blasts, as well as their possible implications in regulatory mechanisms involving HLA-class II molecules are discussed.

Abstract
This study defines the risk of central nervous system (CNS) relapse in patients undergoing bone marrow transplantation (BMT) for acute lymphoblastic leukemia (ALL) in remission, with no posttransplant prophylactic CNS therapy. Ninety-two consecutive patients in complete remission received BMT for ALL (n = 82) or high-grade non-Hodgkin's lymphoma with poor prognostic factors at diagnosis (n = 10). Sixty-six patients received allogeneic BMT (Allo-BMT) and 26 patients, without an identical sibling, underwent autologous BMT (Auto-BMT). Fifteen patients had CNS involvement at diagnosis and underwent BMT in first remission. Eight patients experienced CNS relapse after BMT, corresponding to a probability of 11% at 3 years. Apart from a history of prior CNS involvement, no patient characteristic evaluated statistically influenced CNS relapse after BMT. The probability of CNS relapse was 5.5% for the 70 patients without history of CNS involvement and 27.5% for the 22 patients with prior CNS involvement. However, subgroup analysis showed that the increased risk of CNS relapse is mainly observed in Auto-BMT patients with history of prior CNS involvement, particularly in patients undergoing BMT in first remission (three of five Auto-BMT versus one of ten Allo-BMT). Taking into account the multiple factors which influence the occurrence and the treatment of CNS leukemia, the results on this retrospective study suggests that (1) for patients without CNS involvement at diagnosis and for whom BMT is performed in first remission, cranial irradiation before BMT and posttransplant prophylactic CNS therapy can be omitted because of the low probability of CNS relapse after BMT (3.4%), when total-body irradiation (TBI) is included in the conditioning regimen; and (2) the difference observed between Allo-BMT and Auto-BMT patients with previous CNS involvement and undergoing BMT in first remission could indicate that graft-versus-host leukemia acts even in the CNS in Allo-BMT patients.

Abstract
We previously demonstrated that after allogeneic bone marrow transplantation (BMT) a subset of CD8, HNK1, and DR-positive T lymphocytes are able to inhibit CFU-GM and BFU-E growth with an HLA-DR restriction. In this study we investigated whether these cells, present in normal marrow in low concentration (less than 1%), play the same role. HNK1-positive sorted marrow cells forming rosettes (E+C) were able to inhibit BFU-E and CFU-GM growth when added back to the marrow E-C at a ratio of 1:10 (HNK1+ E+C/E-C) in a range from 40% to 60%. This inhibitory effect was also detected for a cellular ratio of 1:100, which is the normal marrow value for this subset of T cell. HNK1+ DR+-sorted E+C after double-immunofluorescent labeling also showed the same inhibitory activity as the HNK1+ E+C, whereas the negative fraction including all the other E+C had no detectable inhibitory activity. CD3 and CD8 antigens were also present on the membrane of these cells, as demonstrated in two cases by double-immunofluorescent labeling performed with anti-CD3 or anti-CD8 monoclonal antibodies (MoAbs) and HNK1 MoAb, respectively, and subsequent cell sorting. Blocking experiments, performed by adding in culture anti-CD4 and anti-CD8 MoAbs to HNK1+ T cells showed that only the last MoAb was able to prevent inhibition of hematopoietic colony growth. These results confirmed that one subset of CD3+, CD8+, HNK1+, and DR+ T cells was responsible for in vitro inhibition of normal hematopoiesis. In addition, this inhibition was genetically restricted to HLA-class II antigens, since in three co-culture experiments with unrelated bone marrow cells inhibition occurred only when cells with one haplo-identical HLA-DR antigen was added back to the culture. Indeed, this effect was really HLA-DR restricted, since in blocking experiments with different anti-HLA class II MoAbs (anti-DR, anti-DP, and anti-DQ MoAbs) only an anti-HLA-DR MoAb was able to prevent the colony growth inhibition by CD3+ HNK1+, or CD8+ HNK1+ E+C. In conclusion, the CD3+, HNK1+, CD8+, DR+ cells may be the T-cell subset able to inhibit normal hematopoiesis with an HLA-DR restriction.

Abstract
We describe the case of a patient exposed to chloramine-T who experienced severe asthmatic symptoms when spraying chloramine-T solutions. The patient used chloramine-T as a sterilising agent in medical facilities. Occupational asthma due to chloramine-T was diagnosed by means of specific bronchial provocation test (occupational type). We stress the risk of exposure to high levels of chloramine-T and the importance of this compound as a cause of occupational asthma.

Abstract
Whole blood serum (WBS) and platelet-poor plasma-derived serum (PDS) from the same normal subject were compared for their abilities to support human megakaryocyte (MK) colony formation. In all cases, PDS promoted the growth of a higher number (20-50%) of MK colonies than did WBS. Increasing amounts of WBS decreased the number of colonies, whereas increasing concentration of PDS had no marked effects. Crude platelet extracts or platelet secretory products from thrombin-activated platelets also elicited an inhibition of MK colony formation in a dose-dependent manner. A complete inhibition was found for a dose equivalent to 1.10(9) platelets/ml and a 50% inhibition in a range of 1.10(7)-1.10(8) platelets/ml. These platelet products were also inhibitory for erythroid progenitor growth. Platelets from two patients with gray platelet syndrome elicited only a minor inhibition of MK growth, suggesting that the platelet alpha granule is the origin of this inhibition. When platelet extracts were acid-treated, the biological activity of the inhibitor on CFU-MK and CFU-E growth was 20-50-fold higher. In addition, a potent stimulatory activity on the growth of day 7 CFU-GM was observed. The enhancement of biological activities by acid treatment suggests that type beta transforming growth factor (TGF-beta) could be involved in this platelet inhibitory activity. The homogeneous native TGF-beta (from 1 pg to 1 ng/ml) produced the same effects previously induced by platelet products. It totally inhibited CFU-MK growth (at a 500 pg/ml), it inhibited CFU-E growth, and it stimulated growth of day 7 CFU-GM in the presence of a colony-stimulating factor. The inhibition of CFU-MK growth was also observed on purified progenitors. In conclusion, these results suggest that TGF-beta may be implicated in negative autocrine regulation of megakaryopoiesis. However, since this molecule has ubiquitous biological activities, its physiologic relevance as a normal regulator of megakaryopoiesis requires further investigation.

Abstract
We have used DNA sequence polymorphism analysis to document engraftment after T cell-depleted bone marrow transplantation (BMT), with a selected panel of four DNA probes. In contrast to nondepleted BMT recipients, the patients who received T cell-depleted marrow exhibited a mixed blood chimerism. This mosaicism was observed before graft failure or relapse in six patients. However, in five other patients, this mixed chimerism was not followed by these complications with a follow-up of 9 to 31 months after transplantation. Our results support the hypothesis that transplanted bone marrow T cells may help to maintain engraftment by eliminating host cells that can cause graft failure.

Abstract
We performed a longitudinal study of the phenotype and functions of granular lymphoid cells from seven patients with T8 hyperlymphocytosis and neutropenia. Whereas cells retained a T3+ T8+ (six cases) or T3- T8+ (one case) phenotype at different examinations, the expression of natural killer (NK)-related antigens (HNK1- and Leu11-defined antigens) exhibited striking variations, some of which were also observed after in vitro culture. Similarly, natural or antibody-mediated cytotoxic activities fluctuated in vivo and in vitro. Cells from the patient with T3- T8+ proliferation were able to inhibit directly the growth of early CFU-GM, CFU-E, and BFU-E and to a lesser extent of late CFU-GM, as shown by cultures of autologous blood or marrow progenitors after depletion (and subsequent addition) of granular cells. In the other six patients with T3+ T8+ cells, no such effect was found. However, after a 24-hour incubation of the progenitors with the granular cells, CFU-GM growth was clearly inhibited; this was not observed in all experiments, a finding which may be related to the spontaneous variations of cell killer functions. Finally, no correlation was noted between the clinical course or extent of lymphoid proliferation and cell function or phenotype or with the monoclonal (two cases), polyclonal (three cases) or germ-line (one case) patterns of T cell receptor beta gene configuration.

Abstract
Among nine cases of early erythroblastic leukemia previously diagnosed using a panel of antibodies, two patients have erythroid blasts expressing glycophorin A, seven patients have blasts with a more immature phenotype. These immature blasts were labeled by the FA6-152 monoclonal antibody when studied with the immunogold technique. The blasts exhibited large nucleoli, and their cytoplasm contained numerous ribosomes and large mitochondria. In the Golgi apparatus several granules resembled the theta granules as previously described and contained ferritin molecules in the absence of rhopheocytosis. A large proportion of these blasts exhibited a platelet peroxidase (PPO)-like activity. As the blasts from the two other patients with a more mature phenotype and glycophorin A reactivity lacked this PPO, this enzyme seems to be restricted to the more immature cells. Since in these leukemic samples immature erythroid blasts were admixed to promegakaryoblasts, immunogold labeling was also performed with antiplatelet antibodies. This latter population which was labeled with C17, a monoclonal antibody to platelet glycoprotein IIIa, showed strong PPO activity but lacked theta granules and ferritin. In the normal bone marrow enriched by panning for CFU-E (8%) and depleted in progenitors of other lineages, blast cells showing characteristics similar to leukemic erythroid blasts were seen. They exhibited theta granules and ferritin and a proportion of them also had a PPO-like activity. Thus, a PPO reaction is not restricted to the platelet-megakaryocyte line. In conclusion, a PPO-like activity and ferritin molecules were present in immature leukemic erythroid blasts. Similar cells could be identified from normal bone marrow.
