Abstract
BACKGROUND Estimating the age at death is a common procedure in the fields of forensic human identification and anthropological/archaeological investigations. Root translucency and periodontosis are regressive parameters used to estimate the age of adults, more specifically in Lamendin's method - established in 1992 in a French population. This study aimed to test the applicability and validity of Lamendin's method in a Brazilian osteological collection. METHODS The sample consisted of 74 single-rooted teeth obtained from 50 skeletal remains (mean age: 53.20 ± 16.17 years) from Southeast Brazil. Lamendin's method was applied to enable a comparison between chronological (CA) and estimated ages (EA). A new population-specific equation was designed for the studied sample and the outcomes were compared with those obtained with Lamendin's original equation. RESULTS The original methods led to a general underestimation of 11.32 years (8.83 years in males and 15.91 years in females). The method had a better performance among individuals between 40 and 59 years (mean differences between CA and EA: 4.8 years). The population-specific equation led to a mean overestimation of -2.04 years in males, and a mean underestimation of 3.77 years in females. Underestimations were considerably higher in other age groups. CONCLUSION Despite the apparent improvements, both the original and the population-specific equations revealed coefficients of concordance that were constantly low between CA and EA. These outcomes suggest restrictions to the application of Lamendin's method in the forensic field, especially for human identification. The method, however, seems to be applicable for anthropological/archaeological applications.

OBJECTIVES This study aimed to describe the results of a modified sympathicotomy (uniportal VATs with stellate ganglion sparing) for cardiac sympathetic denervation (CSD) in the setting of untreatable ventricular tachycardia.
BACKGROUND. CSD, in patients with refractory ventricular tachycardia (VT), is comprehensively recognized as an important treatment option for patients with structural heart disease as well as congenital inherited arrhythmia syndrome. A recent case series demostrated the feasibility of the modified technique.
METHODS We consecutively enrolled 8 patients with refractory VT. Baseline demographic, medical, and surgical data as well as arrhythmia outcomes and procedural complications were evaluated.
RESULTS A total of 8 patients ( 7 pts NIDCM, 1 pt IDCM with mean age:68+-8 years) were enrolled for the treatment of refractory VT with a modified CSD technique. Mean sympathicotomy length were 7.3 (SD 3) min per side. 3/8 patients underwent monolateral (LCSD) sympathicotomy due to strong adesion in the right pleural cavity. Mean follow up was 13 months (SD 6). No complication occurred during the sympathicotomy. An overall reduction in VT burden and VT number was observed after the CSD despite an in-hospital early recurrence in 3 patients.
CONCLUSIONS A modified CSD (sympathicotomy T2–T5) with stellate ganglion sparing and the use of unipolar radiofrequency is feasible, effective, and safe in the setting of untreatable VT. Abstract Figure. VT trend

Abstract
Pectus excavatum is a chest wall malformation with a strong psychological and aesthetic impact. Rarely, pectus excavatum patients can show respiratory or cardiac symptoms occurring mainly during physical exertion. We report a case of a 34-year-old pregnant woman with a severe degree of pectus excavatum who developed serious cardiovascular disease resulting in spontaneous twin abortion at the twenty-first week of gestation. Cardiovascular disease was resolved after open surgical correction of pectus excavatum. This case shows how a tardive diagnosis and a delayed surgical approach for pectus excavatum can lead to severe consequences.

Abstract
We describe a rare case of Dirofilaria repens infection presenting as peripheral lung nodules and mimicking a metastatic focus from a previously diagnosed cutaneous melanoma. To avoid invasive investigations before arriving at the correct diagnosis, dirofilariasis should be included as a part of the diagnostic process in subjects with lung nodules who live in (or have traveled to) endemic regions.

Abstract
BACKGROUND Lung transplantation (LT) is a viable option for a select group of patients with end-stage lung disease. However, infections are a major complication after LT, accounting for significant morbidity and mortality. Several germs may be responsible; multidrug-resistant Gram-negative (MDR-GN) bacteria are emerging. Colistin is widely used in the treatment of these infections and is administered by inhalation and/or parenterally. At our institution, in patients with tracheostomy, colistin is administered by direct instillation in the airway during bronchoscopy. We reviewed a series of patients who underwent LT complicated by postoperative MDR-GN bacterial pulmonary infection. METHODS From January 2015 to May 2017, 26 lung transplants were performed. In the postoperative course, 14 (54%) developed MDR-GN bacterial infection; respiratory specimen culture, blood tests, and chest X-ray were considered. Colistin was the only antibiotic usable. Thirteen patients received intravenous (IV) colistin; in the subgroup of patients with tracheostomy, colistin was instilled directly in the airway, and 6 patients received inhaled colistin. RESULTS Seven patients needed tracheostomy. Pseudomonas aeruginosa was the predominant infection (86%), with Acinetobacter baumanii seen in 2 cases (14%). An early clinical-laboratory response was observed in 9 patients (64%). White blood cell count and C-reactive protein values improved (P = .02 and P = .001, respectively). A significant reduction in bacterial load was observed on microbiologic bronchoalveolar lavage specimens. CONCLUSION Colistin instilled directly in the airway did not show side effects. The combination of IV and inhaled/instilled colistin could be a useful treatment option for MDR-GN infections after LT.

Abstract
BACKGROUND Lung transplantation (LT) is only therapeutic option for patients affected by chronic respiratory failure. Chronic rejection, also known as bronchiolitis obliterans syndrome (BOS), is still the main cause of death and the most important factor that influences post-transplantation quality of life. Currently available therapies have not been proven to result in significant benefit in the prevention or treatment of BOS. Extracorporeal photopheresis (ECP) seems to reduce the rate of lung function decline in transplant recipients with progressive BOS. METHODS From 1991 until now, 239 LTs were performed at our center. Fifty-four patients (22.5%) developed BOS; 15 of these (27.7%) were treated with ECP. At the beginning of the treatment, all patients showed a mean decline of forced expiratory volume in 1 second (FEV1) from baseline values of 45.8% ± 17.2%; 2 patients were in long-term oxygen therapy. RESULTS Mean follow-up from November 2013 to June 2016 was 11.6 ± 7 months. Twelve patients (80%) showed lung function stabilization with an FEV1 range after treatment between -6% to +8% from the pre-treatment values. We did not report any adverse effects or increase of infections incidence. DISCUSSION ECP seems to be an effective and well-tolerated therapeutic option for LT patients with BOS in terms of stabilization of lung function and increased survival.

Abstract
BACKGROUND Acute kidney injury and chronic kidney failure are serious complications after lung transplantation. Glomerular filtration rate (GFR) is the primary indicator of renal function. Several equations have been proposed to evaluate the estimated GFR (eGFR). We compared three different equations to determine which has the better correlation with the development of acute and chronic renal failure in lung recipients. METHODS Twenty-two patients with a mean age of 54.4 ± 8.5 years underwent lung transplantation from 2010 to 2015. Thirteen (59%) had pulmonary fibrosis, 7 (32%) emphysema, 1 (4.5%) bronchiectasis, and 1 (4.5%) lymphangioleiomyomatosis. In all patients, eGFR was measured preoperatively using Cockcroft-Gault (CG), Modification of Diet in Renal Disease (MDRD), and Levey's Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations. In 20 patients (90%) eGFR was calculated at 1, 3, and 6 months. RESULTS According to CKD-EPI and MDRD, eight patients (36.3%) had preoperative reduction in eGFR, whereas 6 patients (27.2%) had preoperative reduction according to the CG (P = .04). The mean values were higher for the CG (103.2 vs. 102 vs. 94.4). Five patients (22.7%) developed perioperative acute renal failure requesting a dialysis treatment; four of these showed a preoperative eGFR to the highest CG (P = .05). At 1 and 6 months after lung transplantation, the CG, MDRD and CKD-EPI eGFR values were, respectively, 86.6, 84.1 and 76.6 mL/min/1.73m2 and 75.8, 72.7, and 72.3 mL/min/1.73m2. CKD-EPI eGFR values are more predictable than the other equations of AKI. CONCLUSIONS Preoperative assessment of eGFR using the MDRD and CKD-EPI seems to correlate better than the CG to the prediction of acute renal failure, whereas for the chronic form the three equations seem equivalent.

Abstract
Chronic hepatitis C virus (HCV) infection is characterized by persistent B-cell activation, with enhanced differentiation and reduced proliferative ability. To assess the possible role of HCV in altering B-cell subset distribution, we examined ex vivo frequencies and B-cell inhibitory receptor expression in 37 chronic HCV-infected patients and 25 healthy donors (HD). In addition, we determined whether short-term exposure to culture-derived HCV (HCVcc) resulted in B-cell subset skewing and/or activation. There was a statistically significant increase in the frequencies of immature transitional, activated memory and tissue-like memory (TLM) B cells in HCV-infected patients compared with HD. We also found that the frequency of memory B cells correlated with serum HCV RNA levels. The proportion of B cells expressing the marker of exhaustion Fc receptor-like 4 (FcRL4) was generally low even though significantly higher in the patients' memory B-cell compartment compared with HD, and a positive correlation was found between the frequencies of the patients' TLM FcRL4+ B cells and serum alanine aminotransferase and histological activity index at liver biopsy. Exposure to cell-free HCVcc in vitro did not result in B-cell skewing but induced significant activation of naïve, TLM and resting memory B cells in HCV-infected patients but not in HD, in whom cell-associated virus was an absolute requirement for activation of memory B cells. These findings provide corroborative evidence in favour of significant B-cell subset skewing in chronic HCV infection and in addition show that expression of exhaustion markers in selected B-cell subsets does not impair virus-induced B-cell activation.

Abstract
Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease, characterized by the progressive loss of motor neurons within the central nervous system. Neural degeneration and inflammatory processes, including activation of the complement system are hallmarks of this pathology. Our past work in ALS animal models (hSOD1 G93A rodents) has revealed that blockade of the receptor for complement activation fragment C5a (C5aR), improves ALS-like symptoms and extends survival. We now show that the levels of C5a and C5b-9, but not C3a nor C4a, are significantly elevated in plasma from ALS patients compared to healthy controls. C5a was also elevated within leukocytes from ALS patients suggesting heightened C5a receptor interaction. Overall, these findings indicate that there is enhanced peripheral immune complement terminal pathway activation in ALS, which may have relevance in the disease process.

Abstract
Epstein-Barr virus (EBV) is a γ-herpes virus, responsible for infectious mononucleosis in immunocompetent hosts. Cellular immunity appears rapidly during EBV primary infection, keeping it silent despite long-life persistence in B lymphocytes. Defects of the EBV-specific cellular immunity are supposed to be the basis of post-transplantation lymphoproliferative disorders, promoted by high levels of immunosuppression. We retrospectively reviewed 197 solid organ transplant recipients to investigate EBV-specific lymphocyte responsiveness using Enzyme-linked ImmunoSpot assay (EliSpot), which assesses the EBV-specific interferon (IFN)-γ producing peripheral blood mononuclear cells, and kinetics of EBV infection/reactivation post-transplantation using quantitative real-time polymerase chain reaction (PCR) on whole blood. Overall, 102 of the 197 patients (51.8%) showed EBV responsiveness at the EBV-EliSpot assay: 68 (66.6%) showed a persistently positive EBV response in 3 or more determinations and 34 (33.3%) had transient episodes of nonresponsiveness. Ninety-five (48.2%) patients were persistently EBV nonresponders. EBV-DNAemia data were available for 58 patients: 27.6% presented at least one episode of EBV-DNA occurrence. No differences were found in EBV-EliSpot response stratification between the groups of patients who experienced episodes of EBV reactivation and those without EBV-DNAemia. However, EBV DNAemia peak values tended to be higher in the first year post-transplantation in the group of patients with a persistent positive EBV-specific immune response. EBV viral load quantitation in blood and EliSpot EBV-specific immune response determination may represent a powerful tool for monitoring solid organ transplant recipients, guiding immunosuppression modulation in patients with active EBV replication.

Abstract
Cellular immune response has been demonstrated to play a role in the control of human cytomegalovirus (HCMV) replication in organ transplant recipients. Herein, HCMV-specific T-cell response and association to the onset of organ infection/disease were prospectively evaluated by EliSPOT assay in a population of 46 lung transplant (LT) recipients at 1, 3, 6, 9 and 12 months post-transplantation. According to our centre's practice, a combined prolonged antiviral prophylaxis (HCMV-IG for 12 months and ganciclovir or valganciclovir for 3 weeks from postoperative day 21) was given to all LT recipients. HCMV-DNA was concomitantly detected on bronchoalveolar lavage (BAL) and whole blood by real-time PCR. Approximately one third of patients resulted HCMV persistently non-responder; the rate of HCMV infection, as evaluated by HCMV-DNA positivity, tended to be higher in non-responders. Mean viral load on BAL was significantly higher in non-responders vs other patients (p <0.001). Temporal profile of infections appeared related to the HCMV responder status with a shorter time to onset of infection post-transplantation and a longer duration in non-responders. The occurrence of organ disease (i.e. pneumonia) tended to be higher in non-responders, with poor prognosis, as death occurred in one of three non-responder patients that developed HCMV pneumonia. The lack of HCMV-specific cellular response can contribute to the onset of organ infection and disease also in patients in which antiviral prophylaxis was adopted; this could be due to the potential occurrence of incomplete control of replication in lungs or a delayed priming of T-cell reconstitution.

Abstract
The occurrence and clinical impact of herpes simplex virus (HSV) were evaluated in 342 bronchoalveolar lavage specimens from 237 patients. HSV-1 and HSV-2 were detected in 32.1% and <1% of patients, respectively. A significant difference of HSV-1 prevalence and load was found in relation to admission to intensive care unit, mechanical ventilation and mortality within 28 days; in particular, a viral load ≥10(5) copies/mL bronchoalveolar lavage fluid was significantly associated with critical features. No association was found with immune status or other characteristics. Nine of 21 (42.9%) cases of ventilator-associated pneumonia were positive for HSV-1, with poor outcome in six.

Abstract
AIM The epidemiology of lower respiratory tract (LRT) viral infections in adults is probably underestimated and the high frequency of multiple viral infections complicates the evaluation of the possible role of the single viruses. The aim of this study was to investigate the clinical epidemiology and impact of respiratory viral pathogens, in particular of those singularly detected, in bronchoalveolar lavage (BAL) specimens from hospitalized adult patients. METHODS A panel for the detection of 16 respiratory viruses was used to prospectively evaluate 324 consecutive specimens obtained from 219 patients over a full-year period. RESULTS Two-hundred-twenty-one specimens (68.2%) were positive for at least one virus, 119/324 (36.7%) to a single viral agent. The most commonly detected viruses were herpesviruses HHV-7 (26.2%), human cytomegalo-virus (HCMV, 22.2%), HHV-6 (19.8%), EBV (12.7%), enteroviruses and rhinoviruses (both 11.7%), parainfluenza viruses (4.9 %), and metapneumovirus (4.0%). Human cytomegalo-virus was significantly more prevalent as single viral pathogen with a viral load >105 copies/ml associated to pneumonia in solid organ transplant recipients. Other viral pathogens might account for some cases of pneumonia or respiratory insufficiency, although multiple infections were common. CONCLUSIONS The use of a comprehensive diagnostic panel for respiratory viral infections may be useful to clarify the epidemiology and clinical impact of viral pathogens in hospitalized adult patients. The occurrence of multiple infections is a common finding and results should be interpreted taking into account the clinical context as well as viral load and the biological characteristics of each virus.

Abstract
A link between temporal lobe epilepsy (the most common epileptic syndrome in adults) and neuropeptides has been established. Among neuropeptides, the possible involvement of bradykinin has recently received attention. An autoradiographic analysis has shown that B1 receptors, which are physiologically absent, are expressed at high levels in the rat brain after completion of kindling, a model of temporal lobe epilepsy. Thus, the present work aimed at investigating the functional implications of this observation, by studying the effect of B1 receptor activation on extracellular glutamate levels in the kindled hippocampus. Microdialysis experiments have been performed in two groups of rats, control and kindled. Glutamate outflow has been measured under basal conditions and after chemical stimulation with high K+ (100 mM in the dialysis solution). Basal glutamate outflow in kindled animals was significantly higher than in controls. High K+-evoked glutamate outflow was also more pronounced in kindled animals, consistent with the latent hyperexcitability of the epileptic tissue. The B1 receptor agonist Lys-des-Arg9-BK induced an increase of basal and high K+-evoked glutamate outflow in kindled but not in control rats, and the selective B1 receptor antagonist R-715 prevented both these effects. Furthermore, R-715 significantly reduced high K+-evoked glutamate outflow when applied alone. These data suggest that the bradykinin system contributes to the modulation of epileptic neuronal excitability through B1 receptors.

Abstract
Modifications in tumour antigen-derived epitopes that stabilize the major histocompatibility complex (MHC)-peptide complex result in enhanced stimulatory capacity and improved immunogenicity of the altered peptide. These epitope analogues are attractive candidates for the development of peptide-based vaccine trials. Any modification, however, in tumour antigens may induce T-cell responses that could either fail to react against the naturally occurring peptides or represent only a subset of the total antigen-specific repertoire. In the present study, we performed a critical analysis of the ability of cytotoxic T-lymphocyte (CTL) clones, derived from two melanoma patients through stimulation with the A27L peptide analogue, to cross-react with the naturally processed Melan-A/MART-1 (Melan-A) peptides in terms of T-cell receptor (TCR) affinity, functional avidity and fine antigen specificity. We found that all the A27L-specific clones analysed possessed a very low avidity for the natural Melan-A peptides, and that their binding affinity for human leukocyte antigen (HLA) tetramers complexed with both the modified and the natural Melan-A peptides did not strictly correlate with their functional avidity. We also observed that these clones were able to cross-recognize both natural Melan-A peptides in one patient, but only one peptide in the second patient. We discuss the capability of the A27L peptide analogue to stimulate all the available Melan-A-specific repertoire.

Abstract
Vitiligo is a common skin disease characterized by the presence of well circumscribed, depigmented, milky white macules devoid of identifiable melanocytes. Although the detection of circulating anti-melanocytic antibodies and of infiltrating lymphocytes at the margin of lesions supports the view that vitiligo is an autoimmune disorder, its etiology remains unknown. In particular, it is still a matter of debate whether the primary pathogenic role is exerted by humoral or cellular abnormal immune responses. In this study, the presence of specific cytotoxic T lymphocyte responses against the melanocyte differentiation antigens Melan-A/MART1, tyrosinase, and gp100 in vitiligo patients have been investigated by the use of major histocompatibility complex/peptide tetramers. High frequencies of circulating melanocyte-specific CD8+ T cells were found in all vitiligo patients analyzed. These cells exerted anti-melanocytic cytotoxic activity in vitro and expressed skin-homing capacity. In one patient melanocyte-specific cells were characterized by an exceptionally high avidity for their peptide/major histocompatibility complex ligand. These findings strongly suggest a role for cellular immunity in the pathogenesis of vitiligo and impact on the common mechanisms of self tolerance.

Abstract
Introduction of somatostatin analogs has greatly contributed to improving the prognosis of acromegaly. Although the majority of patients are effectively treated by these agents, resistance occurs in a subset of patients. So far, resistance to somatostatin has never been associated with mutations of the somatostatin receptor subtypes (sst2 and sst5) that inhibit GH secretion. Molecular analysis of genomic DNA from pituitary tumor and peripheral blood obtained from an acromegalic resistant to octreotide showed a somatic activating mutation of Gsalpha (Arg201Cys), no mutation in sst2, and one polymorphism (Pro109Ser) and one germ line mutation (Arg240Trp) in sst5. Wild-type (WT) and mutant sst5 PCR products were cloned and transfected into Chinese hamster ovary K1 cells. In Chinese hamster ovary K1 cells stably expressing mutant sst5, somatostatin-28 was less potent in inhibiting cyclic AMP levels than in WT cells. Proliferation of mutant cells exceeded that of WT by 50%. Moreover, somatostatin reduced cell growth and MAPK activity in WT but not in mutant cells in which the peptide even increased MAPK activity. We suggest that this mutation that abrogates the antiproliferative action of somatostatin and activates mitogenic pathways may be involved in the resistance to somatostatin treatment.

Abstract
While tumor-associated antigen (TAA)-specific CD8(+) T lymphocytes have been detected in metastatic melanoma patients, immune response in early disease phases has not yet been carefully evaluated. We looked for circulating cytotoxic T lymphocytes (CTL) directed against Melan-A / MART1, tyrosinase, gp100 and MAGE-3 antigens in patients with a diagnosis of primary cutaneous melanoma by using fluorescent HLA-A2 tetramers. In five out of six cases high numbers of CD8(+)/tetramer(+) cells could be detected by flow cytometry, and in four patients lymphocyte populations specific for two different melanoma antigens (Melan-A/MART1 and tyrosinase) were contemporaneously present. The TAA-specific cells could represent as much as 1/220 T lymphocytes in the circulating CD8(+) population. When tetramers were used to monitor the in vitro expansion of TAA-specific CTL precursors upon antigen-specific stimulation, a diverse expansion potential was evidenced in CTL from the different donors and, more strikingly, in CTL specific for the different TAA. Melan-A/MART1-specific CTL clones derived from two patients exhibited a broad range of avidity. Only the highest avidity clones, representing about 50 % of the cases analyzed, were tumor specific. By correlating tetramer staining with clone avidity, we found that tetramer fluorescence intensity could represent a good indicator of TCR affinity, but not of overall clone avidity.

Abstract
Different transcription factors have been shown to control the transition of naive T cells into T helper 1 (Th1)/Th2 subsets. The T-cell-specific transcription factor GATA-3 is known to be selectively expressed in murine developing Th2 cells and to exert a positive action on Th2-specific cytokine production. Investigating GATA-3 gene regulation in human T cells we have found that naive T cells highly express GATA-3, and during early T2 or T1 polarization, respectively, they either maintain or quickly down-regulate expression. In developing T2 cells, as well as in committed Th2 cell lines and clones, we found a positive correlation among GATA-3, interleukin (IL)-5 and IL-4 gene expression kinetics, supporting the positive action of GATA-3 on Th2-specific cytokine production. A possible relationship between GATA-3 gene expression and the down-regulation of the IL-12 receptor (beta2-chain; IL-12Rbeta2) gene was evident only in the early phases of T2 polarization (within 24 hr), and not demonstrated at later times. During T-cell commitment the presence of IL-4 in the culture was essential to maintain or enhance GATA-3 transcription, while IL-12 was not necessary for full repression of GATA-3. Finally, we showed selective GATA-3 up-regulation in human Th2 cell lines and clones and the maintainance of a low basal level of GATA-3 expression in Th1 cells upon activation.

Abstract
Accumulating evidence indicates that peripheral lymphocyte variants with altered antigen receptor expression may be capable of expressing recombination-activating genes (RAG). We and others recently observed functional RAG gene products in mature T cells with defective TCR expression (MacMahan and Fink, Immunity 1998. 9: 637 - 647; Lantelme et al., J. Immunol., 2000. 164: 3455 - 3459). Here, the association between TCR expression and RAG activity was assessed further in lymphocytes from patients with defective responses to DNA damage. We show that T cells with altered TCR surface expression are present in increased numbers in these patients and that they express RAG genes. The finding of RAG gene expression by TCR variants suggests the possibility that secondary V(D)J rearrangements could be induced in these cells to rescue their defective phenotype and cellular function. Moreover, as V(D)J recombination has been implicated in chromosome translocations involving antigen receptor genes, we discuss a possible relationship between altered TCR expression, RAG activity and the frequent lymphoma-specific translocations observed in these patients.

Abstract
The recombinase-activating genes, RAG-1 and RAG-2, can be expressed by a subset of B cells within germinal centers, where they mediate secondary V(D)J rearrangements. This receptor revision mechanism could serve either receptor diversification or tolerance-induced functions. Alternatively, it might rescue those cells the receptors of which have been damaged by somatic mutation. Less is known about the occurrence of similar mechanisms in T cells. Here we show that mature T cells with defective TCR surface expression can express RAG genes and are capable of initiating secondary V(D)J rearrangements. The possibility that a cell rescue mechanism based on the generation of a novel Ag receptor might be active in peripheral T cells is envisaged.

Abstract
Evidence suggests the existence of a direct relationship between cellular Gs alpha content and activation of the adenylyl cyclase system. Data on Gs alpha levels in endocrine tumors that depend on cAMP for growth, particularly pituitary adenomas, are still limited. The levels of Gs alpha protein were evaluated in 11 GH-secreting adenomas with Gs alpha mutations (gsp+) and 15 without (gsp). Complementary DNAs from gsp+ tumors contained very low amounts of wild-type Gs alpha sequences, indicating a preponderance of the mutant Gs alpha transcripts in these tumors. Immunoblotting of Gs alpha protein showed that the two isoforms were present at high levels in all gsp-, but were undetectable or barely detectable in gsp+. The low Gs alpha content in gsp+ tumors was not due to a reduction in ribonucleic acid synthesis or stability, as Gs alpha messenger ribonucleic acid levels were similar in wild-type and mutant tissues. Treatment of gsp- cells with cholera toxin caused a marked reduction of Gs alpha levels. As in other cell systems cholera toxin increases Gs alpha degradation, our data are consistent with an accelerated removal of mutant Gs alpha. This may represent an additional mechanism of feedback response to the constitutive activation of cAMP signaling in pituitary tumors with mutations in the Gs alpha gene.

Abstract
Because phosphodiesterase (PDE) expression and activity are controlled by cAMP, we investigated whether activating mutations of Gs alpha gene that occur in human GH-secreting adenomas are associated with increased PDE activity. We studied 10 adenomas with wild-type Gs alpha (gsp-) and 8 with mutant Gs alpha (gsp+). Although, in the absence of PDE inhibitors, intracellular cAMP levels were similar in gsp+ e gsp- adenomas, the PDE blockade with 3-isobutyl-1-methylxanthine induced a marked increase in cAMP in all but one gsp+ adenoma (% increase: from 77 to 2900) and a slight rise in only 2 gsp-. Similar results were obtained with the PDE4 selective inhibitor 4-[3-(cyclopentyloxy)-4-methoxyphenyl)]-2-pyrrolidinone. In vitro GH release was significantly higher in gsp+ than in gsp- adenomas (315 +/- 158 vs. 82 +/- 53 micrograms/well; P < 0.01), and PDE blockade caused a further increase in 3 of 5 gsp+ adenomas but not in gsp- tumors. By direct measurement, PDE activity was about 7-fold higher in gsp+ than in gsp- adenomas (320 +/- 213 vs. 48 +/- 23 pmol/min.mg protein; P < 0.05) and was largely 4-[3-(cyclopentyloxy)-4-methoxyphenyl]-2-pyrrolidinone sensitive. This study first demonstrates that activating mutations of the Gs alpha gene that naturally occur in pituitary adenomas is associated with an increased PDE activity that might, at least partially, counteract the constitutive activation of the cAMP-dependent pathway.

Abstract
G proteins mediate signal transduction in a variety of cell systems. As the expression of these proteins has not yet been investigated in detail in human pituitary tumors, we evaluated the presence of G proteins in a series of tumors including six non-functioning adenomas, five GH-secreting adenomas, three prolactinomas and one TSH-secreting adenoma, using immunoblotting and immunohistochemistry. By immunoblotting, Gi1/2alpha was undetectable in six and barely detectable in nine tumors. A similar pattern of expression was observed by probing with the antibody to Gi3alpha, which detected a very weak band in 11 tumors and no protein in four. In contrast, using large amounts of membrane proteins (40 microg), both Gi1/2alpha and Gi3alpha were detected, although at very low levels, in the negative tumors. The low expression of these proteins appeared to be specific to tumoral tissues, as both Gi1/2alpha and Gi3alpha were abundant in normal human and rat pituitary. In all tumors, Go alpha, the two Gs alpha forms, Gq/11 and G beta were present in significant amounts. Semiquantitative analysis indicated that Gs alpha was clearly detected when 2.5 microg loaded proteins were used, whereas Gi1/2alpha and Gi3alpha were barely detected with 5 microg. By immunofluorescence, all tumors studied were markedly positive for Gs alpha that was immunolocalized at the cell periphery, whereas they showed a weak positivity for Gi1/2alpha and Gi3alpha. The study is the first to provide evidence for a low expression of Gi proteins, which are involved in the transduction of inhibitory signals, in pituitary adenomas.

Abstract
Although hypothalamic neurohormones were originally identified on the basis of their ability to influence hormone release from the target cells, it is at present clear that these agents are involved in the control of several biological processes that include cell proliferation and differentiation as well as hyperplasia and neoplastic transformation. Hypothalamic neurohormones bind specific receptors belonging to the G-protein-coupled receptor superfamily to generate intracellular effectors, in particular cAMP and calcium. Several in vivo and in vitro studies suggest the presence of functional and/or structural alterations in the receptor/effector molecules involved in the transduction of hypothalamic neurohormone action in the pituitary. The present study reports the frequent presence in pituitary tumors of cellular alterations that result in amplification of stimulatory signals, particularly activation of the cAMP-dependent pathway, and reduction of inhibitory inputs, both events having possible implications in tumor formation and/or progression.

Abstract
Pituitary cells appear to be programmed to proliferate in response to cyclic adenosine monophosphate (cAMP), leading to tumorigenesis. Stimulatory neurohormones and inhibitory inputs normally act in opposition to control cAMP levels, but receptor/postreceptor alterations may affect their relative effects. Most growth hormone (GH), corticotropin (ACTH)-, prolactin (PRL)-, and gonadotropin-secreting adenomas and nonfunctioning pituitary adenomas (NFPA) possess specific thyrotropin-releasing hormone (TRH) receptors, normally coupled with cytosolic [Ca2+]i increase and diacyl glycerol production. These cells are also sensitive to other peptides such as vasoactive intestinal peptide (VIP) and pituitary adenylyl cyclase-activating peptide (PACAP), which activate adenylyl cyclase in many hormone-secreting adenomas and in all NFPA. The two main inhibitory agents controlling pituitary function are somatostatin (SS) and dopamine (DA), which have been reported to reduce hormone hypersecretion and tumor growth in a variable percentage of patients. Inhibition of adenylyl cyclase activity and cytosolic [Ca2-]i levels is involved in the transduction of DA signals in normal and tumoral mammotrophs, but in GH-secreting adenomas DA receptors are exclusively and defectively coupled only with [Ca2+]i reduction. The abnormal expression of these receptors can amplify stimulatory signals with both secretory and proliferative potential. The availability of specific G proteins may qualify the cell response to inhibitory agents. For example, in a subset of NFPA, SS alone or DA alone causes an abnormal increase in [Ca2+]i levels due to Ca2+ mobilization from intracellular stores.

Abstract
Normal or elevated thyrotropin (TSH) levels in hyperthyroid patients are characteristic of rare TSH-secreting pituitary adenoma (TSH-oma), which is easily detectable by computed tomographic (CT) scan or magnetic resonance imaging (MRI). Other diagnostic aids are an absent/impaired TSH response to thyrotropin-releasing hormone (TRH), discrepant TSH and alpha-subunit responses to TRH, high sex hormone-binding globulin (SHBG) levels, high alpha-subunit levels, and a high alpha-subunit/TSH molar ratio. Familial studies help rule out thyroid hormone resistance (RTH). Surgical removal of TSH-oma leads to clinical and biochemical remission in most patients. In surgical failures, radiotherapy and octreotide treatment have a high success rate. Undetectable TSH 1 week postsurgery suggests a definitive cure, backed up by tests for cosecreted hormones from the adenoma and dynamic tests of TSH suppression.

Abstract
It is well established that dopamine (DA) plays an important role in inhibiting anterior pituitary function. DA receptors present in the pituitary show the pharmacological and biochemical characteristics of the D2 receptor; in fact, they are coupled to the inhibition of both adenylyl cyclase (AC) activity and the reduction of cytosolic free Ca2+ levels ([Ca2+]i) suggesting the involvement of different G-proteins. While the DA receptors present in human PRL-omas display these characteristics, no information is available on the coupling mechanism(s) of DA receptors expressed in nonfunctioning pituitary adenomas (NF-PA). In the present study, the effect of DA on AC activity and [Ca2+]i was investigated in 8 NFPAs surgically removed by the transphenoidal route. DA, at concentrations between 0.01 and 10 mumol/l, had no effect on cAMP formation in any tumor (from 27.6 +/- 11.9 to 27.9 +/- 11.0 pmol/mg prot/min; NS). By contrast, DA was effective in reducing [Ca2+]i levels either in resting conditions or after TRH stimulation in 5 out of 8 tumors, suggesting that NFPA express DA receptors with a defective transduction mechanism. As in these tumors SRIH caused the expected inhibition of both AC activity (from 31.4 +/- 9.3 to 24.4 +/- 11.0 pmol/mg prot/min; p < 0.005) and [Ca2+]i levels, it is likely that the lack of DA action on AC activity may be due to functional/structural properties of DA receptors expressed in NFPA, instead of a defect at the level of Gi proteins. In conclusion, these data indicate that DA receptors expressed in NFPA show a defective transduction mechanism, leading to a partial inhibitory response.

Abstract
Chromogranin B and secretogranin II, two members of the granin family, are known to be post-translationally modified by the addition of O-linked carbohydrates to serine and/or threonine, phosphate to serine and threonine, and sulfate to carbohydrate and tyrosine residues. In the present study, chromogranin B and secretogranin II were used as model proteins to investigate in which subcompartment of the Golgi complex secretory proteins become phosphorylated. Monensin, a drug known to block the transport from the medial to the trans cisternae of the Golgi stack, inhibited the phosphorylation of the granins, indicating that this modification occurred distal to the medial Golgi. Monensin also blocked the addition of galactose to O-linked carbohydrates and the sulfation of the granins, confirming previous data that these modifications take place in the trans Golgi. To distinguish, within the trans Golgi, between the trans cisternae of the Golgi stack and the trans Golgi network, we made use of the previous observation that brefeldin A results in the redistribution to the endoplasmic reticulum of membrane-bound enzymes of the trans cisternae of the Golgi stack, but not of the trans Golgi network. Brefeldin A treatment abolished granin sulfation but resulted in the accumulation of phosphorylated and galactosylated granins. Differential effects of brefeldin A on membranes of the Golgi stack versus the trans Golgi network were also observed by immunofluorescence analysis of marker proteins specific for either compartment. Our results suggest that the phosphorylation of secretory proteins, like their galactosylation, largely occurs in the trans cisternae of the Golgi stack, whereas the sulfation of secretory proteins on both carbohydrate and tyrosine residues takes place selectively in the trans Golgi network.
