Abstract
Introduction: We report the development and preliminary evaluation of a novel dynamic bioreactor to culture ovarian cortical tissue strips that leverages tissue response to enhanced oxygen transport and adequate mechanical stimulation. In vitro multistep ovarian tissue static culture followed by mature oocyte generation, fertilization, and embryo transfer promises to use the reserve of dormant follicles. Unfortunately, static in vitro culture of ovarian tissue does not promote development of primordial to secondary follicles or sustain follicle viability and thereby limits the number of obtainable mature oocytes. Enhancing oxygen transport to and exerting mechanical stimulation on ovarian tissue in a dynamic bioreactor may more closely mimic the physiological microenvironment and thus promote follicle activation, development, and viability. Materials and Methods: The most transport-effective dynamic bioreactor design was modified using 3D models of medium and oxygen transport to maximize strip perifusion and apply tissue fluid dynamic shear stresses and direct compressive strains to elicit tissue response. Prototypes of the final bioreactor design were manufactured with materials of varying cytocompatibility and assessed by testing the effect of leachables on sperm motility. Effectiveness of the bioreactor culture was characterized against static controls by culturing fresh bovine ovarian tissue strips for 7 days at 4.8 × 10-5 m/s medium filtration flux in air at -15% maximal total compressive strain and by assessing follicle development, health, and viability. Results and Conclusions: Culture in dynamic bioreactors promoted effective oxygen transport to tissues and stimulated tissues with strains and fluid dynamic shear stresses that, although non-uniform, significantly influenced tissue metabolism. Tissue strip culture in bioreactors made of cytocompatible polypropylene preserved follicle viability and promoted follicle development better than static culture, less so in bioreactors made of cytotoxic ABS-like resin.

Abstract
BACKGROUND Delirium is thought to be common across various settings of care; however, still little research has been conducted in rehabilitation. AIM We investigated the prevalence of delirium, its features and motor subtypes in older patients admitted to rehabilitation facilities during the three editions of the "Delirium Day project". METHODS We conducted a cross-sectional study in which 1237 older patients (age ≥ 65 years old) admitted to 50 Italian rehabilitation wards during the three editions of the "Delirium Day project" (2015 to 2017) were included. Delirium was evaluated through the 4AT and its motor subtype with the Delirium Motor Subtype Scale. RESULTS Delirium was detected in 226 patients (18%), and the most recurrent motor subtype was mixed (37%), followed by hypoactive (26%), hyperactive (21%) and non-motor one (16%). In a multivariate Poisson regression model with robust variance, factors associated with delirium were: disability in basic (PR 1.48, 95%CI: 1.17-1.9, p value 0.001) and instrumental activities of daily living (PR 1.58, 95%CI: 1.08-2.32, p value 0.018), dementia (PR 2.10, 95%CI: 1.62-2.73, p value < 0.0001), typical antipsychotics (PR 1.47, 95%CI: 1.10-1.95, p value 0.008), antidepressants other than selective serotonin reuptake inhibitors (PR 1.3, 95%CI: 1.02-1.66, p value 0.035), and physical restraints (PR 2.37, 95%CI: 1.68-3.36, p value < 0.0001). CONCLUSION This multicenter study reports that 2 out 10 patients admitted to rehabilitations had delirium on the index day. Mixed delirium was the most prevalent subtype. Delirium was associated with unmodifiable (dementia, disability) and modifiable (physical restraints, medications) factors. Identification of these factors should prompt specific interventions aimed to prevent or mitigate delirium.

Abstract
Introduction Delirium and sarcopenia are common, although underdiagnosed, geriatric
syndromes. Several pathological mechanisms can link delirium and low skeletal muscle mass, but few studies have investigated their association. We aimed to investigate (1) the association between delirium and low skeletal muscle mass and (2) the possible role of calf circumference mass in finding cases with delirium. Methods The analyses were conducted employing the cross-sectional “Delirium Day” initiative, on patient 65 years and older admitted to acute hospital medical wards, emergency departments, rehabilitation wards, nursing homes and hospices in Italy in 2017. Delirium was diagnosed as a 4 + score at the 4-AT scale. Low skeletal muscle mass was operationally defined as calf circumference ≤ 34 cm in males and ≤ 33 cm in females. Logistic regression models were used to investigate the association between low skeletal muscle mass and delirium. The discriminative ability of calf circumference was evaluated using non-parametric ROC analyses. Results A sample of 1675 patients was analyzed. In total, 73.6% of participants had low skeletal muscle mass and 24.1% exhibited delirium. Low skeletal muscle mass and delirium showed an independent association (OR: 1.50; 95% CI 1.09–2.08). In the subsample of patients without a diagnosis of dementia, the inclusion of calf circumference in a model based on age and sex significantly improved its discriminative accuracy [area under the curve (AUC) 0.69 vs 0.57, p < 0.001]. Discussion and conclusion Low muscle mass is independently associated with delirium. In patients without a previous diagnosis of dementia, calf circumference may help to better identify those who develop delirium.

Abstract
The reactive and reparative capacity of injured tissue when treated with either Pulsed Electromagnetic Fields (PEMFs) or with immunomodulator drugs (Prostaglandin E2 and Thymopentin) was evaluated. A morphological and quantitative evaluation was made of the interactions and the interferences on the structural stages of tissue repair processes. When PEMFs were used the time required for new tissue to completely cover the wound was 26 days after surgery, instead of 30 days for control conditions or for treatment with PGE2 or Thymopentin. PEMFs showed accelerated healing process. Both PGE2 and Thymopentin should be considered, in association with other drugs, in an attempt to strengthen the various immunomodulative phases of the reconstitution of injured tissue.

Abstract
The most frequent chromosomal translocations in pediatric acute myeloid leukemia affect the 11q23 locus and give rise to mixed lineage leukemia (MLL) fusion genes, MLL-AF9 being the most prevalent. The MLL-AF9 fusion gene has been shown to induce leukemia in both mouse and human models. In this study, we demonstrate that leukemogenic activity of MLL-AF9 requires RUVBL2 (RuvB-like 2), an AAA+ ATPase family member that functions in a wide range of cellular processes, including chromatin remodeling and transcriptional regulation. Expression of RUVBL2 was dependent on MLL-AF9, as it increased upon immortalization of human cord blood-derived hematopoietic progenitor cells with the fusion gene and decreased following loss of fusion gene expression in conditionally immortalized mouse cells. Short hairpin RNA-mediated silencing experiments demonstrated that both the immortalized human cells and the MLL-AF9-expressing human leukemia cell line THP-1 required RUVBL2 expression for proliferation and survival. Furthermore, inhibition of RUVBL2 expression in THP-1 cells led to reduced telomerase activity and clonogenic potential. These data were confirmed with a dominant-negative Walker B-mutated RUVBL2 construct. Taken together, these data suggest the possibility of targeting RUVBL2 as a potential therapeutic strategy for MLL-AF9-associated leukemia.

Abstract
The purpose of this study was to evaluate osteochondral lesions of the knee, treated intraoperatively with low-power laser stimulation, and assess results at 24 weeks. Surgery was performed under general anesthesia on six rabbits; a bilateral osteochondral lesion was created in the femoral medial condyles with a drill. All of the left lesions underwent immediate stimulation using the diode Ga-Al-As laser (780nm), whereas the right knees were left untreated as control group. After 24 weeks, the explants from the femoral condyles, either treated employing laser energy or left untreated, were examined histomorphometrically. Results obtained on the lased condyles showed good cell morphology and a regular aspect of the repaired osteocartilaginous tissue.

Abstract
AIM It has been established that antiphospholipid antibodies (aPL) are associated with recurrent abortions, but the pathophysiologic mechanisms that characterize thrombosis and recurrent pregnancy losses are still not clear.However, it is known that they are associated with the presence of antibodies directed against anionic phospholipids and putative cofactors. In this study the pathogenetic role of annexin A5, a potent anticoagulant cofactor protein for its anticoagulant property in recurrent abortions, was investigated. METHODS Endothelial cells of human umbilical veins ''EAHY2936 Line'' in culture were used, incubated with antiphospholipid anticardiolipin (ACA) antibodies purified from plasma of patients with recurrent abortions. The expression of annexin A5 on the cells with ACA was investigated by immunofluorescence and by confocal microscope. The negative control was also carried out: EAHY cells in cultivation medium without ACA. RESULTS Confocal analysis revealed a uniform distribution of annexin A5 on the cellular membranes in the negative control. Instead, in EAHY cells with ACA, the annexin A5 appears distributed in irregular manners on the cellular membranes (cytoplasmic and nuclear). CONCLUSION The results of an irregular ''cluster'' distribution of annexin A5 on the EAHY cells in presence of aPL, and in agreement with the literature, demonstrated that aPL, inhibiting annexin A5 ability to protect anionic phospholipid, promote the coagulation factors to diffuse laterally against phospholipids.

Abstract
Nucleoporin 98 (NUP98) is a component of the nuclear pore complex that facilitates mRNA export from the nucleus. It is mapped to 11p15.5 and is fused to a number of distinct partners, including nine members of the homeobox family as a consequence of leukemia-associated chromosomal translocations. NUP98-HOXA9 is associated with the t(7;11)(p15;p15) translocation in acute myeloid leukemia (AML), myelodysplastic syndrome, and blastic crisis of chronic myeloid leukemia. Expression of NUP98-HOXA9 in murine bone marrow resulted in a myeloproliferative disease progressing to AML by 7-8 months. Transduction of NUP98 fusion genes into human CD34(+) cells confers a proliferative advantage in long-term cytokine-stimulated and stromal cocultures and in NOD-SCID engrafted mice, associated with a five- to eight-fold increase in hematopoietic stem cells. NUP98-HOXA9 expression inhibited erythroid and myeloid differentiation but enhanced serial progenitor replating. NUP98-HOXA9 upregulated a number of homeobox genes of the A and B cluster as well as MEIS1 and Pim-1, and downmodulated globin genes and C/EBPalpha. The HOXA9 component of the NUP98-HOXA9 fusion protein was protected from cullin-4A-mediated ubiquitination and subsequent proteasome-dependent degradation. In NUP98-HOX-transduced CD34(+) cells and cells from AML patients with t(7;11)(p15;p15) NUP98 was no longer associated with the nuclear pore complex but formed intranuclear aggregation bodies. Analysis of NUP98 allelic expression in AML and myelodysplastic syndrome showed loss of heterozygosity observed in 29% of the former and 8% of the latter. This was associated with poor prognosis.

Abstract
The Notch family of transmembrane receptors has been implicated in the regulation of many developmental processes. In this study, we evaluated the role of Notch4 in immature hematopoietic progenitors by inducing, with retroviral transduction, enforced expression of Int-3, the oncogenic and constitutively active form of mouse Notch4. Int-3-transduced human myeloid leukemia (HL-60) cells demonstrated significantly delayed expression of differentiation markers following retinoic acid and 12-0-tetradecanoylphorbol 13-acetate treatment. Furthermore, HL-60 cells expressing Int-3 displayed a slower growth rate than cells infected with void virus, and accumulation in the G0/G1 phases of cell cycle. Transduction with deletion mutants of Int-3 defined the importance of individual domains of the protein (in particular, the ANK domain and the C-terminal domain) in the inhibition of differentiation and growth arrest of HL-60 cells. When mouse bone marrow enriched for stem cells (5-fluorouracil-resistant, lineage negative) was transduced and cultured for two weeks, the Int-3-transduced population displayed a lower expression of differentiation markers and a three- to five-fold higher frequency of colony-forming cells (CFU-GM/BFU-E) than control cultures. These results strongly support the notion that Notch signaling inhibits differentiation and promotes expansion of hematopoietic stem/progenitor cells.

Abstract
The aim of this study was to verify the effects of laser therapy performed with Ga-Al-As diode laser (780 nm, 2500 mW) on cartilage cells in vitro. The cartilage sample used for biostimulation was taken from the knee of an adult patient. The cultures were divided into four groups: Groups I, II, III were subjected to biostimulation with different laser parameters; Group IV did not received any treatment. The laser biostimulation was conducted for five consecutive days. At the end of the treatment, cell count and MTT tests were performed to assess cell metabolism. The data showed good results in terms of cell viability in the groups treated with laser biostimulation compared to the untreated group. The results obtained with the use of this new low-power diode laser Ga-Al-As device in the biostimulation of the cartilage tissue, permits us to consider the use of this device clinically.

Abstract
An in vitro study was performed to evaluate the laser biostimulation effect on cartilage using a new gallium-aluminium-arsenic diode laser. Chondrocyte cultures were derived from rabbit and human cartilage. These cells were exposed to laser treatment for 5 days, using the following parameters: 300 joules, 1 watt, 100 (treatment A) or 300 (treatment B) hertz, pulsating emission for 10 minutes, under a sterile laminar flow. Control cultures (no treatment) received the same treatment with the laser device off. Cell viability was measured by MTT assay at the end of the laser treatment and then after 5 days. Neither rabbit nor human cultured chondrocytes showed any damage under a light microscope and immunostaining control following laser treatment. The MTT test results indicated a positive biostimulation effect on cell proliferation with respect to the control group. The increase in viability of irradiated chondrocytes was maintained for five days following the end of the laser treatment. The results obtained with the Ga-Al-As diode laser using the above tested parameters for in vitro biostimulation of cartilage tissues provide a basis for a rational approach to the experimental and clinical use of this device.

Abstract
The osteointegration of Hydroxyapatite (HA), Titanium (Ti-6Al-4V: Ti), Zirconia (ZrO2), Alumina (Al2O3) and 2 biological glasses (AP40 and RKKP) was comparatively investigated in normal and osteopenic rats by means of histomorphometry. Thirty-six Sprague Dawley female rats were left intact (Group C) while 36 were ovariectomized (Group OVX). Group C and OVX were further divided into 6 subgroups. After 16 weeks all animals were submitted to the femoral implant of nails made of the above-mentioned materials. Eight weeks after implantation the animals were euthanized, the femurs were harvested for histomorphometric analysis. The data showed that: (1) all the tested materials were biocompatible in vitro; (2) no significant differences existed in Affinity Index (AI) of Group C; and (3) results from paired comparison applied to the AI showed significant differences among the Groups C and OVX. The AI did not significantly change among intact groups, while it significantly decreased when some materials were implanted in OVX subgroups (AP40, ZrO2 and Ti-6Al-4V: p < 0.0005, p < 0.05 and p < 0.01). It is confirmed that bone mineral density is a strong predictor of the osteointegration of an orthopedic implant and that the use of pathological animal models is necessary to completely characterize biomaterials.

Abstract
The purpose of this study was to evaluate whether intraoperative laser biostimulation can enhance healing of cartilaginous lesions of the knee. Surgery was performed on eighteen rabbits: a bilateral chondral lesion of 1.25 +/- 0.2 mm in length and 0.8 +/- 0.2 mm in width was created in the femoral medial condyle with a scalpel. The lesion in the left knee of each animal was treated intraoperatively using the diode Ga-Al-As 780nm. laser (300 Joules/cm2, 1 Watt, 300 Hertz, 10 minutes), while the right knee was left untreated, as control group. The animals were divided into three groups, A, B and C, according to the survival time after surgery, two, six and twelve weeks, respectively. The explants from the femoral condyles, both treated employing laser energy and left untreated, were examined histologically. Results showed a progressive filling with fibrous tissue of the cartilaginous lesion treated with laser irradiation, while no changes in the original lesion of the untreated group were observed at the end of the study. Maybe, in this experimental research, underexposure to laser irradiation was the cause for the absence of the necessary conditions for biostimulation.

Abstract
The purpose of this study was to evaluate whether low-power laser biostimulation of the osteo-chondral lesions of the knee could by itself reduce repair healing time. Surgery was performed on eighteen rabbits; a bilateral osteo-chondral lesion of 2.5mm in diameter and 2mm depth was created in the femoral medial condyle with a drill. The left knee of each animal was treated intraoperatively using the diode Ga-Al-As laser (780nm) with the following parameters: 300 Joules/cm2, 1 Watts, 300 Hertz, 10 minutes; the right knee was left untreated, as control group. The animals were divided into three groups, A, B and C, according to the survival time after surgery, two, six and twelve weeks, respectively. The explants from the femoral condyles, either treated employing laser energy or left untreated, were examined histomorphometrically. Results after laser treatment showed faster healing of the lesion at week 2 (p=0.043) and an overall improvement in cellular morphology (p=0.044), while a more regular aspect of the osteocartilaginous tissue was observed at week 12 (p=0.004). A relationship between laser biostimulation properties and healing of the osteo-chondral defect has been demonstrated.

Abstract
Bisphosphonates (BPs) are commonly used in the treatment of myeloma-associated osteolytic lesions. Recent reports have suggested that BPs may also exert direct antitumor effects on myeloma cells. Here, we show that the treatment of myeloma cell lines with the combination of the potent BP zoledronate and dexamethasone inhibits cell growth and synergistically induces apoptotic cell death, providing a rationale for potential applications in vivo.

Abstract
The aim of this study was to verify the effects of laser therapy performed with Ga-Al-As Diode Lasers (780 nm, 2500 mW) on human cartilage cells in vitro. The cartilage sample used for the biostimulation treatment was taken from the right knee of a 19-year-old patient. After the chondrocytes were isolated and suspended for cultivation, the cultures were incubated for 10 days. The cultures were divided into four groups. Groups I, II, III were subject to biostimulation with the following laser parameters: 300 J, 1 W, 100 Hz, 10 min. exposure, pulsating emission; 300 J, 1 W, 300 Hz, 10 min. exposure, pulsating emission; and 300 J, 1 W, 500 Hz, 10 min. exposure, pulsating emission, respectively. Group IV did not receive any treatment. The laser biostimulation was conducted for five consecutive days. At the end of the treatment, the Calcium, Alkaline Phosphate, MTT tests and proteoglycan were performed to assess cell metabolism and toxicity level. The data showed good results in terms of cell viability and levels of Ca and Alkaline Phosphate in the groups treated with laser biostimulation compared to the untreated group. The results obtained confirm our previous positive in vitro results that the Ga-Al-As Laser provides biostimulation without cell damage.

Abstract
The osseointegration of biomaterials for dental and orthopaedic use is a still open topic in experimental and clinical research. Some aspects of this complex mechanism are not completely research. Some aspects of this complex mechanism are not completely explained yet. These reasons make the process of osseointegration a topical subject both in clinical and experimental view points. The authors describe how this complex event has not been studied with standard investigation and report also most of present research lines on the basis of their experience. A particular attention is paid to some factors related to both biomaterial and implant site, which can influence significantly the process of osseointegration.

Abstract
The scope of our study was to verify the effects of a new diode laser device with active material composed of Gallium, Aluminum and Arsenic (Ga-Al-As) configured as MOCVD (780 nm., 3000 mW) for the biostimulation of the cartilage cells in vitro. The condrocytes cells, withdrawn from the cartilage of the medial condyle of the femur of the rabbit, were cultivated, incubated and subject to biostimulation treatment with the laser. The condrocytes cells were placed in 24 Petri dishes at the concentration of 0.25 x 10(5)/ml and divided into 4 groups: 3 group (I, II, III) were treated with the laser and the fourth group (IV) was used as the control group. At the end of the treatment, all four groups, were evaluated with a MTT test and a cell count of the condrocytes cells. Group III (300 J, 1 Watt, 300 Hz, 10' of exposure time with a pulsating emission) provided the best results in terms of cell viability (MTT test) and for the number of cells found in the dishes when compared to the other treated groups and the control group. The results obtained with the use of this new diode laser Ga-Al-As device in the biostimulation of the cartilage tissue, permits us to consider the use of this device clinically.

Abstract
The recently-identified Wiskott-Aldrich syndrome protein gene (WASP) is responsible for the Wiskott-Aldrich X-linked immunodeficiency as well as for isolated X-linked thrombocytopenia (XLT). To characterize the regulatory sequences of the WASP gene, we have isolated, sequenced and functionally analyzed a 1.6-Kb DNA fragment upstream of the WASP coding sequence. Transfection experiments showed that this fragment is capable of directing efficient expression of the reporter chloramphenicol acetyltransferase (CAT) gene in all human hematopoietic cell lines tested. Progressive 5' deletions showed that the minimal sequence required for hematopoietic-specific expression consists of 137 bp upstream of the transcription start site. This contains potential binding sites for several hematopoietic transcription factors and, in particular, two Ets-1 consensus that proved able to specifically bind to proteins present in nuclear extracts of Jurkat cells. Overexpression of Ets-1 in HeLa resulted in transactivation of the CAT reporter gene under the control of WASP regulatory sequences. Disruption of the Ets-binding sequences by side-directed mutagenesis abolished CAT expression in Jurkat cells, indicating that transcription factors of the Ets family play a key role in the control of WASP transcription.

Abstract
The monoclonal antibody UN1 was previously produced in our laboratory on the basis of selective reactivity with human thymocytes and has been classified as unclustered by the 5th and 6th International Workshop and Conference on Human Leukocyte Differentiation Antigens. The antigen recognized by mAb UN1 was found to be expressed on the cell surface of immature human thymocytes, a subpopulation of peripheral T lymphocytes and on several fetal tissues including thymus. The UN1 antigen is purified from children's thymus by ion-exchange and affinity chromatography. Two-dimensional electrophoresis shows that the purified antigen displays microheterogeneity appearing as multiple spots over a pI range 4.4-5.0 at 100-120 kDa. Treatment with neuraminidase results in a retarded migration in SDS-PAGE, an increase in isoelectric point and a reduction in carbohydrate content, indicating a substantial content of sialic acid. Glycosidase digestion and lectin-binding analysis indicate that the carbohydrate residues are essentially O-linked. A preliminary analysis has detected the UN1 antigen in human breast carcinoma tissues but not in normal breast. The biochemical features and the pattern of expression of the UN1 antigen indicate that this molecule may have the characteristics typical of the family of cell-membrane-associated mucin-like glycoproteins; a number of these molecules are thought to have a role in cell-cell interaction, tumor progression and metastasis.

Abstract
The polymerase chain reaction-based differential display method (DDRT-PCR) was used to identify mRNAs differentially expressed during the maturation of human CD34+ progenitor cells stimulated to differentiate in vitro towards granulomonocytic or erythroid lineages with a mixture of hemopoietins (kit ligand + interleukin 3 + GM-CSF in the absence or presence of erythropoietin, respectively). Three cDNA transcripts (B32, B41, and B56) display differential expression during cytokine-induced maturation of CD34+ cells. These clones have no homology with already-described sequences. Primer extension cofirmed the presence of the corresponding mRNA. The levels of mRNA corresponding to B32 are enhanced in the later phases of the granulomonocytic as well as in the erythroid differentiation of CD34+ cells. The mRNA identified by B41 was induced by a late stage in only granulomonocytic differentiation of CD34+ cells. The mRNA corresponding to B56 was instead present in nonstimulated CD34+ cells, declined in the early stages of differentiation, and reappeared at later stages in cells treated with both combinations of cytokines. Expression of these genes was detected in a number of acute myelogenous leukemias, as well as in some leukemic cell lines. B32 and B41 were downregulated in KG-1 cells induced to differentiate towards the monocytic lineage, whereas the levels of B56 were unchanged. In K562 cells, clones B41 and B56 were downregulated only in the late phases of PMA-induced megakaryocytic differentiation and during erythroid differentiation. B32 was rapidly downregulated when K562 cells were induced to differentiate towards either megakaryocytic or erythroid phenotypes. These transcripts represent novel hematopoietic cDNAs that should prove of value for the study of human blood cells and their disorders.

Abstract
Lymphadenectomy in germinal tumors of the testis, in spite of the immediate morbility (postoperative complications) and of the permanent morbility (unejaculation), is still, as regards the group of non-seminoma neoplasms, the most suitable for survival. However, groups of oncologists are seeking the possibility of avoiding this technique at stage I and II of the lesions, with the help, of course, of careful observation by CT, NMR, markers. The use of combined therapies (chemotherapy and radius therapy) has increased survival and the patients' life, allowing a highly satisfying percentage of recovery also in the non-initial stages.

Abstract
BACKGROUND & AIMS Cell-mediated immunity is a feature of Crohn's disease (CD). The heterodimer interleukin (IL)-12, produced by phagocytes, induces T-cell cytokines, primarily interferon (IFN)-gamma. This study examined whether CD lamina propria mononuclear cells (LPMCs) express and release bioactive IL-12. METHODS LPMCs were isolated from 13 patients with CD, 9 with ulcerative colitis (UC), and 13 controls. Messenger RNA for p40 and p35 IL-12 subunits was evaluated by reverse-transcription polymerase chain reaction. IL-12 was measured by enzyme-linked immunosorbent assay in LPMC culture supernatants. The INF-gamma-inducing effect of unstimulated LPMC supernatants was evaluated. RESULTS Messenger RNA for both IL-12 subunits was detected in LPMCs of 11 of 13 patients with CD, 1 of 9 patients with UC, and 1 of 13 controls (P < 0.001). IL-12 was measured (10.5 +/- 2 pg/mL at 24 hours) in unstimulated CD LPMCs and was enhanced by pokeweed mitogen, lipopolysaccharide, and staphylococcal enterotoxin B. No IL-12 was detectable in 8 of 9 patients with UC and 12 of 13 control-unstimulated LPMCs. IL-12 induced by pokeweed mitogen and staphylococcal enterotoxin B in UC was lower than in CD and did not differ from controls. An IFN-gamma-inducing effect was restricted to unstimulated CD LPMC supernatants and was inhibited by an anti-IL-12 antibody in a dose-dependent fashion. CONCLUSIONS IL-12 transcripts are expressed in CD intestinal tissues. CD LPMCs are up-regulated in their capability of releasing bioactive IL-12. Expression and release of bioactive IL-12 seem to differentiate CD from UC.

Abstract
CD69 is an early activation antigen of peripheral blood lymphocytes and is constitutively expressed on a wide variety of bone marrow-derived cells. To further characterize the distribution and understand the potential biological role of the molecule in normal and malignant hematopoiesis, we used a novel high affinity anti-CD69 mAb (UN6) and analyzed hematopoietic progenitor cells together with a panel of myeloid and lymphoid malignancies. We report that mobilized peripheral blood CD34+ cells display detectable levels of CD69 and that the density of membrane expression correlates with the immature phenotype CD34bright Thy-1bright cells. Furthermore, during cytokine-induced differentiation, the expression of CD69 is moderately down-regulated. Analysis of hematopoietic malignancies revealed that CD69 expression correlates with the immature myeloid phenotype. Taken together these data suggest a role of CD69 during the early phase of hematopoiesis and in the leukemic transformation.

Abstract
L-arginine and L-lysine are essential amino acids which seem to possess some properties able to influence bone fractures healing. In fact, they seem to be involved not only in the increase of intestinal calcium adsorption but also in collagen synthesis, in insulin and growth hormone secretion and in osteoblastic activation. So, an experimental in vivo model was carried out by using 50 adult rabbits which, under general anaesthesia, were submitted to an osteotomy of the left fibula. Animals were divided into 5 groups and were daily treated with a mixture of lactose, L-arginine and L-lysine or with the only lactose (control group) at the same dosage as recommended for humans. They were sacrificed after 15, 30, 40, 50 and 60 days for radiological and histological studies. The results of the study showed that the pharmacological mixture containing L-arginine and L-lysine accelerates and ameliorates the healing processes and this positive effect was particularly evident from the 30th day after the osteotomy. We think that these results are linked not only to calcium metabolism but also to different biological properties which positively contribute to a good healing of bone fractures.

Abstract
For many years diagnosis and management of prostatic adenocarcinoma were straightforward. However, with the advent of medical and less invasive therapies for the treatment of prostatic cancer, it has become necessary to know more about the etiology and pathophysiology of the disease. For example, hormonal factors, growth factors, stromal-epithelial interactions and aging have all been implicated in the etiology of the disease. The pathology of the disease demonstrates heterogeneity in the ratio of the stroma to the epithelium in any given patient, and the pathophysiology varies. Recognizing this heterogeneity in the disease, it is clear that no one form of medical or interventional therapy should be expected to result in a complete response.

Abstract
Within an experimental study project about the interaction between Laser and biological tissues, the authors utilized a Laser Doppler Flowmeter device and a Polarographic method to study the cutaneous microcirculation and the tissue pO2. Under standardized conditions, the experimental model considered the microcirculation measurement and the ptiO2 before and after the exsection of a cutaneous lozenge on the animals back realized with traditional surgical methods (scalpel and electrotome) or with a last generation CO2 Laser in continuous and in pulsed mode. The Laser Doppler Flowmeter showed that the largest perturbation of the microcirculatory flux occurred after the exsection realized with the scalpel and the electrotome. The CO2 Laser utilized in continuous mode showed an influence slightly lower on the microcirculation while in pulsed mode the perturbation was absent. The ptiO2 measurement showed similar results emphasizing that the CO2 surgical Laser technique is less invasive than the traditional. To sum up, these functional methods allowed a careful microcirculation an ptiO2 evaluation and provided useful information about vasal and metabolic alterations, showing that the CO2 surgical Laser utilized in pulsed mode appears to be the less harmful surgical technique for the tissues surrounding the exsection site.

Abstract
The common gamma-chain (gamma c) is a shared component of cell-surface receptors for the interleukins- 2, -4 and -7, and possibly others. We studied its expression in cells and cell lines of myeloid origin and found ubiquitous presence of gamma c mRNA in all cells examined. Differential regulation of gamma c expression was observed in myeloid cell lines induced to differentiate in vitro. In K-562 erythromyeloid cells, a sharp rise in the levels of gamma c mRNA and protein accompanied megakaryocytic, but not erythroid, differentiation. Surface binding of interleukin-2, as well as the transcripts for cognate receptor chains, were scarcely detectable in K-562 cells, whereas a significant increase in the binding of granulocyte-macrophage colony-stimulating factor specifically occurred during their megakaryocytic maturation. Our data indicate that expression of gamma c is a common feature of human myeloid cells, and suggest that its expression may be a requirement for human myelopoiesis.

Abstract
Although several reports indicate proliferative and functional effects of human GH (hGH) on peripheral blood lymphocytes (PBL), no information is available about hGH receptor (GHR) expression in PBL subsets. Here, the surface membrane GHR levels were investigated in different human PBL subpopulations using a fluorescein isothiocyanate (FITC)-conjugated monoclonal antibody specific for the GHR (mAb263) in dual fluorochrome flow cytometric assays. Strong GHR expression was found in B-cells (CD20+), whereas CD2+ lymphocytes, including T-cells as well as natural killer cells, exhibited considerably lower levels of receptor expression. Similarly, using FITC-labeled recombinant hGH, receptor expression on CD20+ cells was significantly higher than that on CD2+ cells. Abundant expression of GHR in B-lymphocytes was confirmed by reverse transcriptase-polymerase chain reaction analysis of GHR messenger ribonucleic acid from isolated B-cells. Accordingly, the B-cell merits greater consideration as a GH target cell. The use of FITC-labeled mAb263 and hGH is of potential use for the study of GHR levels in patients exhibiting different types of growth disorders. Because of its high specificity for GHR, FITC-labeled mAb263 is also of considerable value for specifically demonstrating the presence of GHR, because hGH may interact with and act through PRL receptor, as shown previously in human neutrophils.

Abstract
The monoclonal antibody (mAb) UN2 was generated upon immunization of a Balb/c mouse with human thymocytes. mAb UN2 recognized an antigen expressed by a subpopulation of human thymocytes and peripheral blood lymphocytes. In thymus, mAb UN2 recognized cortical cells; its expression was higher on CD3bright than on CD3dim thymocytes. This antigen was also detected on peripheral blood granulocytes, monocytes, platelets and on cell lines MOLT4, U937 and KG1. mAb UN2 was submitted to the 5th International Workshop and Conference on Human Leukocyte Differentiation Antigens, Boston, MA, 1993, and was assigned to the CD31. Expression of the UN2-recognized antigen in malignant lymphoid cells from 57 cases of B-cell chronic lymphoproliferative disease and 4 of B-cell acute lymphoblastic leukemia was analysed in flow cytometry. Among the 57 cases of B-cell chronic lymphoproliferative malignancies studied, 49 were classified as B-cell chronic lymphocytic leukemia. These showed high (86 +/- 8%) UN2 antigen expression. In 8 cases of hairy-cell leukemia the percentage of cells reacting with mAb UN2 was 42 +/- 4%; the fluorescence intensity of labelled cells was lower than that displayed by cells of B-cell chronic lymphocytic leukemia and comparable to that of normal lymphoid cells. mAb UN2 could prove useful in analysis of the lymphoid development and diagnostics of B-cell chronic lymphoproliferative disorders.

Abstract
We have investigated the effect of redox changes in vivo on the differentiation of two human myeloid cell lines, HL-60 and KG-1. The glutathione-depleting agent diethyl maleate (DEM) prevented the development of differentiated features in response to phorbol esters, including adherence of the cells to plastic surfaces and repression of the myeloperoxidase and CD34 genes. Moreover, DEM abolished phorbol 12-myristate 13-acetate-induced activation of the transcription factors AP-1 and Egr-1, suggesting that inhibition of differentiation may be due, at least in part, to redox modifications of these proteins.

Abstract
In order to study the interaction between the laser and biological tissues, we realized an experimental "in vivo" model using 12 Wistar male adult rats (mean b.w. 300 gr.). On the animals, during general anesthesia and after an accurate shearing of the back, we performed a cutaneous lozenge in order to value the characteristics and the possibilities of a last generation laser. It concerns of a CO2 laser (EASY LASER SP5, CLASS IV F.D.A.) with the possibility of employing of different variables. During this study were evaluated the most interesting variables: frequency, power and duty cycle. Among the variables we identified the frequency of the application range of the superpulse effect and the selective photothermolysis. The histological and morphological studies performed on the cutaneous specimens after laser treatment, showed that the correct application of this kind of laser can be an effective help for the surgeon during clinical practice.

Abstract
This paper describes a new murine monoclonal antibody, UN5, raised against human thymocytes. This antibody recognizes a molecule of approximately 45 kDa on thymocytes. Flow cytometric analysis reveals a high intensity of labeling with the majority of thymocytes, whereas only CD20+ cells from peripheral whole-blood samples are weakly stained. Peripheral T cells, granulocytes, platelets and red blood cells do not express this antigen, while monocytes are only weakly labeled by UN5. Furthermore, the UN5 antibody discriminates between different types of B-cell malignancies, reacting with a subgroup of B-cell chronic lymphocytic leukemias and hairy cell leukemias, but not with the other kinds of hematopoietic malignancies tested. Antibody UN5 should prove a useful tool for the study of T-cell precursors and for analysis of both normal and neoplastic B cells.

Abstract
La Peyronie's disease (induratio penis plastica) is a degenerative process involving the penis, whose cause is still not fully explained. Adequate treatment requires the correct staging of La Peyronie's disease. Diagnostic imaging plays a major role after case history and clinics. Several imaging methods are used, including self-photography, plain radiography, CT, pharmaco-cavernosography, plain and duplex Doppler US. Enhanced MRI can be useful to correctly localize the plaques and to detect early changes in La Peyronie's disease, since the fibrous plaques with persistent inflammatory infiltration can be distinguished from the plaques in which inflammation has ceased. The diagnostic approach to La Peyronie's disease has been substantially modified by adding an examination during the erection induced by the intracavernosal injection of papaverine to the examination in the flaccid state. The authors report on the capabilities of unenhanced MRI after the intracavernosal injection of papaverine in steady chronic La Peyronie's disease. MRI was performed with an 0.5 T superconductive unit. Six patients (age range: 46-60 years, mean 52 years) who had been ill for about five years were studied. SE T1-weighted images and FS T2-weighted images were performed in both the flaccid and the erect states. Our results prove MR capabilities in both states in steady chronic La Peyronie's disease, which suggests MRI as the technique of choice for planning surgical treatment.

Abstract
We described some experimental models that were performed in rabbits and in swine in order to evaluate the efficacy of haemoperfusion treatment in hypochloremic alkalosis, uraemia and cytotoxic drug poisoning. In all the models, an extracorporeal circuit was used constituted mainly by a hematic sampling line and a cartridge, containing an anion exchange resin. Access to the blood stream was achieved by isolation and catheterization of the vessels either of the neck or of the leg, or both. The experimental model for the evaluation of haemoperfusion in hypochloremic alkalosis was carried out in rabbits by a pyloric stenosis because its size and weight are similar to new-born humans and its stomach is a simple monogastric one. The hypochloremia and alkalosis were achieved in only 4 hours. The other two experimental models were carried out in pigs because, in these cases, it was better to choose a large size animal with a nutritional similarity to humans, and with the capability to produce a stable chronic renal failure. The pigs were submitted to a bilateral ureter ligature to create a chronic renal failure or to a bilateral renal vessel ligature to avoid the physiologic precipitation of some drugs in renal tubules.

Abstract
The effect of transforming growth factor beta (TGF beta) on the expression of a group of liver genes has been investigated in the hepatoma cell line Hep 3B. TGF beta induces a decrease of the basal level of apolipoprotein A-II (ApoA-II), retinol binding protein (RBP) and alpha-fetoprotein (alpha Fp). Furthermore, TGF beta efficiently antagonizes the IL-6-induction of hemopexin (Hpx) and haptoglobin (Hp) and alpha 1-acid glycoprotein (AGP). These effects of TGF beta are apparently mediated by post-transcriptional mechanism(s). These findings, together with previously reported data on the inhibitory effect of TGF beta on acute phase genes (e.g. ApoA-I and albumin), suggest a role for TGF beta in the regulation of expression of liver genes.

Abstract
High-density lipoprotein (HDL) is shown by ligand blotting to bind membrane-associated polypeptides with sizes of 60, 100 and 210 kDa. Binding was concentration-dependent and competed by excess unlabelled HDL. All the major apolipoproteins of HDL, apoA-I, apoA-II and apoA-IV, bound independently. The 100 kDa and 210 kDa HDL-binding activities were purified from membranes of Hep3B tumour cells by ion-exchange chromatography and gel filtration. The binding activities at 100 kDa and 210 kDa co-purified. After treatment with disulphide-reducing reagent, the 210 kDa band was no longer present and an increase was observed in the amount and binding ability of the 100 kDa polypeptide. The 100 kDa binding protein labelled at the cell surface with 125I could be immunoprecipitated after cross-linking to cell-surface-bound HDL. It is proposed that this HDL-binding activity, a putative cell-surface receptor for HDL, exists totally or in part as a high-molecular-mass complex composed of 100 kDa subunits.

Abstract
Human C-reactive protein (CRP) is the major acute phase reactant during acute inflammation. The human CRP promoter is expressed in an inducible and cell-specific manner when linked to the bacterial CAT gene and transfected into human hepatoma cell cultures. In this paper we analyze the effect of several recombinant cytokines or CRP promoter inducibility in human Hep3B cells. When cytokines are tested singly the major inducer of CRP-CAT fusions is interleukin-6 (IL-6). Maximal CAT gene expression, however, is only achieved when both interleukin-1 beta (IL-1 beta) and IL-6 are present. The response to the two cytokines is cooperative. Cooperativity is maintained when the CRP promoter is linked to a different coding region, that of the bacterial neomycin phosphotransferase II gene. With a series of 5' and 3' deletions we show the existence of two distinct and independent regions responsive to IL-6 and located upstream to the TATA box. The IL-1 effect is exerted at the level of downstream sequences that are probably important for optimal mRNA translatability or nuclear-cytoplasmic transport. Inducibility is not influenced by the activation of protein kinases C or A and does not require new protein synthesis.
