Abstract
Since its start in 2001 the n_TOF collaboration developed a measurement program on fission, in view of advanced fuels in new generation reactors. A special effort was made on measurement of cross sections of actinides, exploiting the peculiarity of the n_TOF neutron beam which spans a huge energy domain, from the thermal region up to GeV. Moreover fission fragment angular distributions have also been measured. An overview of the cross section results achieved with different detectors is presented, including a discussion of the 237Np case where discrepancies showed up between different detector systems. The results on the anisotropy of the fission fragments and its implication on the mechanism of neutron absorption, and in applications, are also shown.

Abstract
The accurate calculations of neutron-induced reaction cross sections are relevant for many nuclear applications. The photon strength functions and nuclear level densities are essential inputs for such calculations. These quantities for 235U are studied using the measurement of the gamma de-excitation cascades in radiative capture on 234U with the Total Absorption Calorimeter at n_TOF at CERN. This segmented 4π gamma calorimeter is designed to detect gamma rays emitted from the nucleus with high efficiency. This experiment provides information on gamma multiplicity and gamma spectra that can be compared with numerical simulations. The code DICEBOXC is used to simulate the gamma cascades while GEANT4 is used for the simulation of the interaction of these gammas with the TAC materials. Available models and their parameters are being tested using the present data. Some preliminary results of this ongoing study are presented and discussed.

Abstract
The neutron capture reactions of the 244Cm and 246Cm isotopes open the path for the formation of heavier Cm isotopes and heavier elements such as Bk and Cf in a nuclear reactor. In addition, both isotopes belong to the minor actinides with a large contribution to the decay heat and to the neutron emission in irradiated fuels. There are only two previous 244Cm and 246Cm capture cross section measurements: one in 1969 using a nuclear explosion [1] and the most recent data measured at J-PARC in 2010 [2]. The data for both isotopes are very scarce due to the difficulties in performing the measurements: high intrinsic activity of the samples and limited facilities capable of providing isotopically enriched samples.
We have measured both neutron capture cross sections at the n_TOF Experimental Area 2 (EAR-2) with three C6 D6 detectors and also at Area 1 (EAR-1) with the TAC. Preliminary results assessing the quality and limitations (back-ground subtraction, measurement technique and counting statistics) of this new experimental datasets are presented and discussed.

Abstract
Introduction: Here in India almost 75% of cancer patient die a sad death of neglect due to lack of awareness about palliative care and low economic level. Surveys in India show that two third of cancer patient do not get proper care during the terminal phase of their life. Palliative care through volunteers can make a significant difference in this respect. Objective: To identify and try to solve, to the extent possible, the main difficulties in giving palliative care to the terminal cancer patients of the area. And evaluate the impact of volunteer's direct care of palliative patients and their families. Methods: Feedback from patients and their relatives regarding the palliative care they receive from nursing home and from volunteers and compare the two. Also feedback from volunteers regarding their positive and negative experience while delivering palliative care service. Then evaluate the data to compare and improve the quality of service. Results: We carried out two studies. One study was undertaken in nursing home palliative care and another was in home setting by volunteers. Both studies were in adult palliative care services. Since January 2015, 496 cases were studied to inquire about their experience in both home based care and nursing home care. Both the studies fulfilled our quality appraisal criteria. One found that those families and patients who received home visits from volunteers were significantly more satisfied. The study highlighted the value of the role of volunteers in better satisfaction of patients and their families. Conclusions: Further research is needed to evaluate the role of volunteers in palliative care and how it can be delivered appropriately and effectively. We also wish to compare our findings with similar studies elsewhere.

Abstract
Objective: In a southern district of West Bengal, India almost 75% of cancer patient die a sad death of neglect due to lack of awareness about palliative care and low economic level. To identify and try to solve to the extent possible the main difficulties in giving palliative care to the terminal cancer patients of the area. Method: Home visit by volunteers and enumeration of the problems as discussed by the patient and their families. Result: Analysis the following data and identify these main problems. Patient problems: Pain, vomiting, respiratory distress, fatigue, etc. Our volunteers visited terminal cancer patients and their families in our areas. Family problems: Inability to match work life with the care of the patients. Adverse attitude of neighbors and local peoples. Social problems: Lack of awareness of the neighbor of local people about cancer and palliative care resulting in isolation of the family. Projected Intervention: Trying to relieve the patient's problems through home based medications and intervention by volunteers and family members. Reorientating the attitude of family members through discussions and other methods of communication (i.e., get-together of cancer survivors). Social effort to raise the awareness of neighbors and local people through discussion and other audio visual method (i.e., poster, leaflet, slide presentation, etc.). Conclusion: We believe that if we are able to continue our program for a long enough period the suffering of the terminal cancer patient and their families might be resolved to a large extent over time.

Abstract
There are many case reports of secondary neoplasms occurring after treatment with alkylating agents. A case of malignant melanoma of the glans penis in a chronic myeloid leukemia (CML) Ph'-positive patient after 13 years on busulfan treatment is described. Since neither impairment of immune status nor increased incidence of secondary neoplasm have hitherto been reported in CML, the suggestion that busulfan has a carcinogenetic effect is discussed.

Abstract
We tested the presence of tumour polypeptide antigen (TPA) in lower urinary tract cells from 59 workers exposed to known bladder carcinogens and from 30 control subjects. We then correlated immunocytological expression and serum TPA levels. Lower urinary tract cells from 31 subjects gave either moderately or strongly positive immunocytological stains. Five also had high serum TPA. The detection of TPA by cytology and in serum differed significantly in workers exposed to cancer agents and the control group.

Abstract
Two specific monoclonal antibodies for breast tissue (DF3 and MCAb-12) and the corresponding tumor markers CA15-3 and MCA in serum have been evaluated in 50 patients with breast cancer and in 15 controls. The expression of these antigens in tissue was poorly correlated with the common prognostic parameters. Their presence in serum was associated with an altered distribution of the antigens in the cell. The expression of these antigens in tissue enables us to select patients for serological follow-up and to evaluate tumor differentiation from a functional point of view.

Abstract
Immunoradiometric determination of the bone isoenzyme of alkaline phosphatase with a method provided by Hybritech Inc., San Diego CA (USA) was carried out in 145 female patients, 97 of whom with radically operated breast cancer and 48 with benign mammary cysts, in order to evaluate the correlation of serum levels with the metabolic process of bone rearrangement in patients with bone metastases. This study shows that skeletal ALP, having high specificity (86.48%) and sensitivity (78.6%) for early progression (the average anticipation time compared to scintigraphic detection was 101 days) could represent a valid marker for bone metastases in association with mucinous markers in the follow-up of patients operated for breast cancer. In addition, dynamic serum determination of skeletal ALP could be a valid help in monitoring the efficacy of therapy in patients with bone progression.

Abstract
With the existing knowledge of ATM's role in therapeutic resistance, the present study aimed at identifying the molecular mechanisms that influence ATM to oscillate between chemoresistance and chemosensitivity. We observed that the redox status of tumors functions as a major determinant of ATM-dependent ‘resistance-to-apoptosis' molecular switch. At a low reactive oxygen species (ROS) condition during genotoxic insult, the ATM/sumoylated-IKKγ interaction induced NFκB activation that resisted JNK-mediated apoptosis, whereas increasing cellular ROS restored ATM/JNK apoptotic signaling. A search for the upstream missing link revealed that high ROS induces oxidation and ubiquitin-mediated degradation of PIASγ, thereby disrupting PIASγ-IKKγ cross talk, a pre-requisite for IKKγ sumoylation and subsequent NFκB activation. Interruption in the PIASγ-mediated resistance pathway channels ATM signaling toward ATM/JNK pro-death circuitry. These in vitro results also translated to sensitive and resistant tumor allograft mouse models in which low ROS-induced resistance was over-ruled in PIASγ knockout tumors, while its overexpression inhibited high ROS-dependent apoptotic cues. Cumulatively, our findings identified an unappreciated yet critical combinatorial function of cellular ROS and PIASγ in regulating ATM-mediated chemosensitization of resistant tumors. Thus, therapeutic strategies employing ROS upregulation to inhibit PIASγ during genotoxic therapy may, in future, help to eliminate the problems of NFκB-mediated tumor drug resistance.

Abstract
AIM To describe the outcome of using diode laser transscleral cyclophotocoagulation (cyclodiode laser) as a safe technique in managing acute angle closure refractory to conventional treatment. METHODS This is a retrospective case series from two ophthalmic units in the United Kingdom. Five patients with acute angle closure refractory to medical and laser treatment underwent cyclodiode laser treatment. Demographic information, symptoms, medical and surgical treatment, visual outcomes, and intraocular pressure (IOP) control were recorded. CASE REPORTS All five patients had symptomatic acute angle closure. Conventional management, including topical and systemic medical treatment, laser iridotomy and laser iridoplasty, did not achieve adequate IOP control or relieve symptoms. Emergency cyclodiode laser treatment was performed within 2-23 days of presentation. All patients subsequently required lensectomy at a later date. At final follow-up (6-14 months), all patients had visual acuity of 6/12 or better with well-controlled IOPs (≤ 17 mm Hg). Only one patient was on topical treatment. One patient developed a persistent low-grade anterior uveitis. DISCUSSION Cyclodiode laser is a safe alternative to emergency lensectomy or trabeculectomy in cases of acute angle closure, which do not respond to treatment.

Abstract
We report our experience concerning bronchoalveolar lavage (BAL) in adult patients affected by haematological malignancies. BAL was performed in patients with documented pulmonary diseases not responding to empirical antibiotic and antifungal therapies. Overall, 25 bronchoscopies were performed in 24 patients. This technique led to pathogen identification in 11 out of 24 patients (45 percent). In particular, we identified four cases of tuberculosis, four of aspergillosis, two of pneumocystosis, two bacterial pneumonia and one pneumonia sustained by CMV (in two cases, pneumonia was polymicrobial). In three cases, where microbiological diagnosis had been obtained by means of other exams (blood culture, urinary antigens), BAL negativity allowed us to exclude alternative diagnoses. Pulmonary location of haematological disease was diagnosed in seven patients. BAL drove a switch therapy in 54 percent of patients. When performed by expert operators, BAL is useful and safe also in frail patients, such as those affected by onco-haematological malignancies.

Abstract
The isoflavonoid compounds 'YS11-YS21' were screened for possible antimicrobial property against 12 known Gram-positive and Gram-negative sensitive bacteria. YS11 and YS16 failed to show antimicrobial activity and YS12, 13, 14, 15, 17, 18 and 20 had moderate antimicrobial action. Compounds YS19 and YS21 showed pronounced antimicrobial property. YS19 and YS21 were then tested in vitro against 214 strains of bacteria from one Gram-positive and six Gram-negative genera. The minimum inhibitory concentration (MIC) of YS19 and YS21 was determined by agar dilution method and ranged from 25 to 200 mg/l in most strains. At concentrations of 30 and 60 microg/mouse these compounds offered significant protection to mice challenged with 50 median lethal dose (MLD) of a virulent strain of Salmonella Typhimurium.

Abstract
A prospective, randomized, double-blind trial was conducted on 124 febrile patients with hematological malignancies to compare teicoplanin with vancomycin as an addition to the initial empiric amikacin-ceftazidime regimen after documented bacteremia due to gram-positive cocci. At enrollment, patients in both groups were comparable with respect to age, sex, underlying hematologic disorders and duration of neutropenia. Rates of therapeutic success were 55/63 (87.3%) in the teicoplanin group and 56/61 (91.8%) in the vancomycin group (p = 0.560). The mean duration of treatment was similar, being 12.2 and 11.4 days, respectively (p = 0.216). Patients treated with teicoplanin remained febrile for slightly longer than those treated with vancomycin (4.9 vs. 4.0 days) (p = 0.013). Thirteen patients experienced an adverse drug reaction, but without any significant difference in the two arms. Isolated staphylococci showed a progressive and significant decrease in susceptibility to both glycopeptides during the 8 study years. The economic analysis performed showed that the addition of vancomycin is cost-saving.

Abstract
Proper collection of glass evidence from crime spot is very important for its latter probative values. Glass evidence when properly collected and analyzed becomes a powerful witness and it can speak truth long after the crime. In criminal investigation glass evidence can tell what had happened and when it had happened. In the present study, a statistical regression analysis relationship between thickness of windowpane used as targets by soft nose bullet using.315"/8mm caliber sporting gun made in ordnance factory, India and various associated impact parameters were investigated. The relationship is found to be reasonably linear. The ballistics performance of windowpane has been found to correlate with the shear strength behavior above the elastic limit.

Abstract
Anthropometry and morbidity profile of fifty randomly selected workers of coal handling plant at a thermal power station of West Bengal having at least five years experience were studied. The mean value of their age, duration of present job and Body Mass Index (BMI) were 34.8 years, 7.86 years and 19.24 respectively. As they were exposed to coal dust (Av. concentration 300-350 mg/M3 of air), warmth (Ambient temperature 40 +/- 5 degrees C), humidity (Relative humidity 80 +/- 5%) and noise [Av. 80 dB(A)], respiratory system was most commonly (72%) effected followed by greying of hair (5.6%), Cloth dusters used by some could not render any discernable protective effect. Addiction was also prevent (62%). Use of proper protective equipments (PPE) supplemented by adequate preplacement and periodic medical examination followed by successful rehabilitation were suggested.
