Abstract
PURPOSE/OBJECTIVE(S) Malignant Pleural Mesothelioma (MPM) is a rare but aggressive intrathoracic malignancy with an overall poor prognosis. Neoadjuvant chemotherapy, surgery and then radiotherapy is the standard of care in early-stage disease. Our study aim is to evaluate the feasibility and toxicity of the novel adjuvant RT in accelerated hypofractionation. We report the lung toxicity preliminary results of the first patients entreated. MATERIALS/METHODS Starting in 2017, 29 MPM patients were enrolled in the trial (IRST trial 163). All patients were treated with accelerated hypofractionated radiotherapy using a helical 3-D CRT and IMRT system and intensity-modulated arc therapy. We conducted a prospective mono-institutional clinical trial enrolling cyto-histological proven, MPM patients. The major exclusion criteria were: previous thorax radiotherapy, contralateral mediastinum involvement (N3) and/or M1, interstitial pneumopathy, active pneumonitis, and fissural disease. The prescription dose was 30 Gy in five daily fractions, while an inhomogeneous dose escalation to 40 Gy was prescribed based solely upon the presence of gross residual tumor. All patients were treated in a 3-D CRT and IMRT system. Patients underwent functional lung study before to start radiotherapy treatment, 2 months and 6 months after the end of the treatment. The organs at risk dose-volume histograms were converted to a 2-Gy equivalent dose, and we closely adhered to the dose constraints of the literature data. We in particular analyzed lung toxicity of the first 20 patients. RESULTS No G3/G4 lung toxicity was found. We reported 65.0% G1 pneumonitis and 10% G2 as acute lung toxicity. The majority of the G1 patients had only mild symptoms and pneumonitis was described only for radiologic features with no need for medical therapy. Other respiratory toxicities were G1-G2 cough in 50% of the patients; G1 dyspnea occurred in 65% of the patients and G2 in the 15%. The total lung mean dose was 18 Gy (range 13 Gy-23 Gy), and the contralateral lung mean dose was 2 Gy (range 1 Gy-2 Gy). The median value of Forced Expired Volume in one second (FEV1) recorded was 75.5% (range: 46%-137%) before the treatment was started, the median value of Forced Vital Capacity (FVC) at baseline was 74 (range 46-123) with progressive decreasing values through time. DLCO has also been reported with a progressive decrease over time after radiotherapy treatment. No case of respiratory failure was reported after treatment. CONCLUSION Treatment of the intact lung with pleural intensity-modulated arc irradiation is a novel treatment strategy that appears to be safe, feasible, and without a high grade of lung toxicity. More investigations are mandatory. The protocol is ongoing.

Abstract
PURPOSE/OBJECTIVE(S) Hypoxia is thought to play a role in tumor development, angiogenesis and growth, and resistance to chemotherapy, antiangiogenic therapy and radiotherapy (RT) in a large number of human cancers. Brain tumors, especially highly aggressive GBM with its necrotic tissue, are more likely to be affected by hypoxia. The median partial pressure of oxygen (PO2) of high-grade gliomas in patients under anesthesia was approximately 5-7 mmHg, with a significant proportion of PO2 values <2.5 mmHg. The radiosensitivity of brain tumors could potentially be increased by performing hyperbaric oxygenation (HBO) before the RT session. We propose an innovative approach to improve the efficacy of accelerated hypofractionated Stereotactic Radiotherapy (HSRT) after HBO (HBO-RT) for the treatment of recurrent HGG (rHGG). The primary objective of this study is to evaluate the disease control rate (DCR) at 3 months. The secondary Objectives are: - Safety assessment (acute and late toxicity). - Overall Survival (OS), - Progression Free Survival (PFS). MATERIALS/METHODS We enrolled 14 patients (aged >18 years) with rHGG detected using MRI. A total dose of 15-25 Gy was administered in daily 5-Gy fractions for 3-5 consecutive days after daily HBO. RESULTS Median follow-up from re-irradiation was 22.8 months (range: 2.0-24.2 months). The disease control rate 3-months after HBO-RT was 50% (23.0-76.9). Six- and 12-month Progression-free survival was 35.7% (95% CI: 13-59.4) and 10.7% (95% CI: 0.8-35.4), respectively. Median overall survival of HBO-RT was 10.7 months (95% CI: 6.6-24.2). No acute or late neurologic toxicity >grade (G)2 was observed. CONCLUSION HSRT combined to HBO seems effective and safe in the treatment of rHGG.

Abstract
Trans-oral robotic surgery (TORS) has changed surgical management
of patients with oropharyngeal squamous cell carcinomas (OPSCC). In
this study we present surgical and oncologic outcomes of patients with
oropharyngeal squamous cell carcinomas, treated using TORS, with and
without an adjuvant therapy. Sixty patients with oropharyngeal
squamous cell carcinomas treated with TORS between January 2008 and
December 2017 have been retrospectively evaluated considering
clinicopathologic features, disease characteristics, adjuvant
treatments and oncological outcomes. TORS was performed for OPSCC to
the base of tongue in 41.7%, tonsils in 46.7%, soft palate and
posterior pharyngeal wall in 3.3% and 5%, respectively. Neck
dissection was performed in 43.3% of patients. Management strategies
included surgery alone in 30%, TORS and adjuvant radiotherapy in
33.3%, and TORS plus adjuvant chemotherapy in 36.7%. The 5-year
overall survival of the total group was 77.6%, the 5-year disease-free
survival rate was 85.2%, and the 5-year local recurrence-free survival
rate was 90.6%. Finally, in selected patients TORS appears to yield
similar oncologic outcomes and functional outcomes to traditional
techniques and non-operative treatment with a possible benefit on
long-term quality of life. The future offers exciting opportunities to
combine TORS and radiotherapy in unique ways. However, further
research is urgently needed to clarify the indications for adjuvant
therapy following TORS resections.

Abstract
PURPOSE The role played by radiation therapy after pleurectomy/decortication or surgical biopsy in malignant pleural mesothelioma is uncertain. We treated patients with accelerated hypofractionated radiotherapy using helical tomotherapy and intensity-modulated arc therapy in an attempt to keep lung toxicity to a minimum. The present study reports the feasibility and toxicity of this approach. MATERIAL AND METHODS Between 2008 and 2012, 36 patients with malignant pleural mesothelioma underwent accelerated hypofractionated radiotherapy to the hemithorax after pleurectomy/decortication (19 patients) or biopsy (17 patients). The prescription dose was 25Gy in five fractions over 5 consecutive days. RESULTS We observed three patients with G3 pneumonitis, five cases of grade 2 dyspnea and six cases of grade 2 cough. The median follow-up was 37 months (range: 3-54 months). The median overall survival for patients who underwent pleurectomy/decortication followed by radiotherapy was 21.6 months [95% confidence interval (95% CI): 15.5-24.1] compared to 19.4 months for patients not submitted to surgery. CONCLUSION Treatment of intact lung with pleural intensity-modulated arc irradiation in malignant pleural mesothelioma patients with malignant pleural mesothelioma proved safe and feasible, with an acceptable rate of pneumonitis. Survival rates were encouraging for both biopsy-only and pleurectomy/decortication groups. We are currently conducting a phase II dose escalation trial in a similar patient setting to prospectively evaluate the impact of radiotherapy on toxicity, disease-free survival and overall survival.

Abstract
Recruitment and activation of eosinophils have been studied intensely in asthma and other allergic diseases. Less is known about the infiltration and degranulation patterns of eosinophils in the tumor stroma. Seven cases of advanced gastric carcinomas were found to be massively infiltrated by eosinophils and studied by light and electron microscopy. Gastric carcinomas, despite having similar numbers of tissue eosinophils, exhibited markedly different degranulation patterns. In 2 cases, resting nondegranulating eosinophils were found. Piecemeal degranulation was the predominant mode of secretion from eosinophils localized within the tumor stroma in 4 cases. Eosinophil exocytosis and cytolysis were rarely observed. In 1 case, crystals morphologically similar to Charcot-Leyden crystals were observed at the extracellular level as well as in phagosomes of tissue macrophages, confirming active sequestrations of eosinophil Charcot-Leyden protein by macrophages in vivo. In the same case, eosinophils showed characteristic features of early and late apoptotic changes, such as condensed chromatin, focal dilatation of nuclear envelope, and preserved plasma membrane. Morphological association between apoptotic eosinophils and deposition of granules in the tumor stroma was found. Extracellular deposition of intact granules from apoptotic eosinophils was distinct from eosinophilic (necrotic) cytolysis, and has reported previously in experimental studies in vitro. To the knowledge of the authors, this case represents the first report of late apoptotic eosinophils that release their granules within the tumor stroma in a human gastric carcinoma.

Abstract
Atherosclerosis is a complex process characterized by an increase in the wall thickness owing to the accumulation of cells and extracellular matrix between the endothelium and the smooth muscle cell wall. This process is associated with different pathologies and it is accelerated in patients with chronic renal failure. In these patients, decreased synthesis of 1,25-dihydroxyvitamin D(3) (1,25(OH)(2)D(3)) leads to secondary complications, like hyperparathyroidism, and treatment with 1,25(OH)(2)D(3) is a common practice. The effect of 1,25(OH)(2)D(3) on vascular smooth muscle cells (VSMCs) calcification has been widely studied, but the role of 1,25(OH)(2)D(3) on VSMC proliferation remains obscure. We have analyzed the effects of 1,25(OH)(2)D(3) in the proliferation of VSMC. We found that 1,25(OH)(2)D(3) (5-100 nM) induces a dose-dependent increase in VSMC proliferation in quiescent cells and in cells stimulated to grow. This increase in proliferation is achieved by shortening the G1 phase. The effect of 1,25(OH)(2)D(3) on VSMC proliferation is mediated by an increase of the expression of vascular endothelial growth factor A (VEGF), as the inhibition of VEGF activity totally blunted the 1,25(OH)(2) D(3)-induced VSMC proliferation. We found this increase in proliferation in vitro, ex vivo in aortic rings incubated with 1,25(OH)(2)D(3), and in vivo in animals with a model of chronic renal failure (5/6 nephrectomy) treated with 1,25(OH)(2)D(3) (1 mug/kg three times a week for 8 weeks). Thus, we conclude that 1,25(OH)(2)D(3) induces increases in VSMC proliferation through an increase on VEGF expression.

Abstract
The development of recurrent pyogenic granulomas as multiple satellite lesions has not been reported in the oral cavity. This report describes an unusual case of intraoral pyogenic granuloma recurring multiple times after surgical excisions with the formation of satellite lesions. Due to failure of surgical management, an alternative approach was taken. We illustrate how the lesions were successfully treated with a series of intralesional corticosteroid injections.

Abstract
Atherosclerosis is the principal cause of myocardial infarction, stroke, and peripheral vascular disease, accounting for nearly half of all mortality in developed countries. The excessive growth of vascular smooth muscle cells is an important component in the development of atherosclerotic lesion. The direct effect of calcitriol and vitamin D analogs on the VSMCs proliferation is not clear. In this study we have analysed if calcitriol, Paricalcitol (19-nor-1,25-dihydroxy-vitamin D2) and EB1089 (experimental analog used as anticancerous) modify proliferation and the expression of vitamin D receptor (VDR) gene that is regulated at the transcriptional level by itself in the VSMCs. VSMCs proliferation was analysed by BrdU incorporation and VDR gene expression using RT-PCR. VSMCs proliferation was stimulated when calcitriol was added to the culture. VSMCs proliferation was significantly lower with analogs at the same dose. With regard to the functional study, the expression of VDR gene was upregulated by calcitriol at a concentration of 100 nM. There were no changes in this expression with the analogs. In conclusion, calcitriol, do not modify VSMCs proliferation. Therefore, Paricalcitol could have a minor proliferating effect on the wall of vessels that vitamin D.

Abstract
UNLABELLED The role of vitamin D in the regulation of blood pressure is unclear. There are no studies that relate Bsm I polymorphism with blood pressure. OBJECTIVE To analyze if Bsm I polymorphism and 25-hydroxyvitamin D (25OHD3) influence blood pressure in healthy individuals with normal blood pressure. METHODS Systolic (SBP) and diastolic (DBP) blood pressure, Body Mass Index (BMI), plasma creatinine, serum calcium, serum phosphorus, serum iPTH, serum 25OHD3 and Bsm I genotype were determined in 590 healthy individuals (260 men and 330 women). Data were analysed using a multiple linear regression model. SBP and DBP were defined as dependent variables and the rest of variables as independent. RESULTS Gender was strongly associated with both SBP (beta: -12.01, p: 0.000) and DBP (beta: -4.78, p: 0.000). Therefore, a separate analysis was performed according to gender. In males, SBP was associated with BMI (beta: 0.83, p: 0.001), 25OHD3, (beta: 0.36, p: 0.000) and genotype (beta: -3.90, p: 0.002); and DBP with 25OHD 3 (beta: 0.16, p: 0.018) and age (beta: 0.28, p: 0.000). Differences of blood pressure among the three genotypes were explored by analysis of variance. SBP was higher in men with bb genotype than in the other genotypes (p: 0.007). In females, 25OHD3 and genotype were not associated with blood pressure. CONCLUSIONS Healthy men with higher levels of vitamin D have higher levels of SBP and DBP. Moreover, men with bb genotype have the highest levels of SBP. Blood pressure levels in women are not influenced by vitamin D nor by Bsml genotype. Our data suggest a possible pathophysiological interaction between vitamin D and sex hormones in blood pressure control.

Abstract
To investigate the ability of cadmium to affect gene transcription in fish, the messenger RNA (mRNA) differential display technique was used to analyze gene expression in the Antarctic icefish Chionodraco hamatus exposed to sublethal doses of cadmium salt. Seven DNA complementary to RNA (cDNA) bands whose steady-state levels of expression significantly changed in response to cadmium exposure were identified. The results obtained show that two groups of genes are affected by cadmium in icefish liver. The first group comprises genes that are up-regulated by the metal: in particular, a gene encoding the heat-shock protein HSP70 and another encoding a protein homologous to GP49 of Sparus aurata egg envelope. The other group comprises genes down-regulated by cadmium. These are the transferrin gene and a gene encoding a protein presenting homology to mouse T2K, a kinase having a role in the prevention of apoptosis. Three cDNAs had no homology to known gene sequences, thus suggesting that may either encode not yet identified proteins, or correspond to untranslated regions of mRNA molecules.

Abstract
The present paper reports the full nucleotide sequence of a cloned cDNA prepared from RNA of lizard ovaries. The open reading frame consists of 2019 nucleotides, which encodes a protein of 673 amino acids belonging to the G protein-coupled receptor superfamily with a large extracellular N-terminal domain involved in hormone recognition. The transmembrane domain ends with a short intracytoplasmic COOH-terminal domain involved in effector activation. Phylogenetic analysis showed that the lizard receptor belongs to the family of follicle-stimulating hormone (FSH) receptors. The hydrophobicity profile is similar to that observed for mammalian and avian FSH receptors. Northern blot analysis of total RNA revealed that the FSH receptor is expressed at high levels in the ovary. In situ hybridization experiments demonstrate that FSH receptor mRNA is specifically localized within the small cells of the follicular epithelium surrounding the oocyte.

Abstract
To investigate the regulation of Chionodraco hamatus metallothionein (MT) encoding genes about 1000-bp regions of both MT-I and MT-II gene promoters were cloned and sequenced. Both promoters were rich in A-T content, and lacked the canonical TATA box; several putative cis-regulatory sequences were also present. In the MT-I promoter, four MREs were identified within the first 300 bp from the ATG codon. In the MT-II promoter, seven MREs were organized into two clusters, one containing three MREs located close to the ATG codon, and the other consisting of four MREs lying 500-900 bp upstream of the transcription starting point. The alignment of the MT-I and MT-II promoter regions showed 57% identity, which increased to 87% in the 300-bp region upstream of the ATG. Only the three proximal putative MREs identified were conserved both in position and sequence. Functional analysis of MT-I and MT-II promoters was performed by introducing deletion mutants of the 5'-flanking regions into vector pGL-3, directly upstream of the firefly luciferase reporter gene. Each construct was tested in the HepG2 cell lines in the absence or presence of zinc or cadmium ions. Maximum inducibility of the MT-II gene promoter was achieved with a construct containing both the proximal and the distal MRE clusters. The lack of the most distally located MRE dramatically affected MT-II promoter sensitivity to metals; removal of the distal cluster of MREs also reduced metal inducibility. The MT-I promoter was more compact, since maximal activity and metal inducibility depended on the presence of the proximal cluster of four MREs. This study suggests that the different organization of the MT-I and MT-II gene promoter regions might account for the observed differences in the basal and metal-induced expression of MT-I and MT-II isoforms in the C. hamatus liver.
