Abstract
INTRODUCTION There is limited data from India regarding elderly non-Hodgkin's lymphomas (NHL) patients. Hence, this audit was planned to study the clinic-pathological features and treatment outcomes in elderly NHL patients. METHODS Retrospective analysis of all NHL patients above age of 59 years treated at the author's institute, between December 2010 and December 2013 was done. Case records were reviewed for baseline details, staging details, prognostic factors, treatment delivered, response, toxicity and efficacy. SPSS version 16 (IBM, Newyork) was used for analysis. Descriptive statistics was performed. Kaplan-Meir survival analysis was done for estimation of progression-free survival (PFS) and overall survival (OS). Univariate analysis was done for identifying factors affecting PFS and OS. RESULTS Out of 141 NHL patients, 67 patients were identified subjected to the inclusion criteria. The median age was 68 years (60-92). Majority were B-cell NHL (86.6%). The commonest subtype in B-cell was diffuse large B-cell lymphoma (55.2%). Fifty-four patients took treatment. The treatment intent was curative in 41 patients (61.2%). Among the patients receiving curative treatment, 16 patients couldn't receive treatment in accordance with NCCN guidelines due to financial issues. Two years PFS was 55%. Two years PFS for B-cell NHL and T-cell NHL were 55% and 50% respectively (P = 0.982). Two years PFS for standard Rx and nonstandard Rx were 62% and 50% respectively, but it didn't reach statistical significance (P = 0.537). Two years OS for the entire cohort was 84%. CONCLUSION Standard treatment in accordance with guidelines can be delivered in elderly patients irrespective of age. There is a need for creating financial assistance for patients, so that potentially curative treatments are not denied.

Abstract
BACKGROUND Neoadjuvant chemotherapy is being increasingly used in patients with unresectable oral cavity cancers to make them resectable. However, its impact on locoregional treatment delivery in such setting remains poorly studied. AIMS To evaluate the impact of neoadjuvant chemotherapy on delivery of further locoregional treatment. SETTINGS AND DESIGN Mono institutional retrospective audit of patients with oral cavity squamous cell cancers treated with neoadjuvant triplet chemotherapy in India. MATERIALS AND METHODS Patients receiving neoadjuvant chemotherapy (n = 14) from May 2012 to April 2014 were matched 1:2 to patients undergoing upfront surgery (n = 28) based on age (>60 or 60 and less), gender (male or female) and subsite site (tongue and floor of mouth or buccoalveolar complex). Data regarding factors related to the delivery of locoregional treatment and toxicities were compiled. STATISTICAL ANALYSIS Descriptive analysis in the form of median (range) for continuous variables and frequencies for categorical variables. RESULTS Patients undergoing neoadjuvant chemotherapy required more extensive resections and had greater operative time (460 vs. 415 min, P < 0.001). A greater incidence of locoregional wound complications was seen as a consequence (57.1% vs. 14.3%, P, 0.01). However, toxicities during radiotherapy were not substantially different between the two groups and compliance to radiation was also similar. Total package time of 100 days or less, was maintained in 90% of patients in both groups. CONCLUSIONS Delivery of neoadjuvant chemotherapy does not impair the ability to deliver locoregional treatment.

Abstract
Background: Acquired immunodeficiency syndrome caused by human immunodeficiency virus (HIV) is an immunosuppressive disease. Over the past decades, it has plagued human health due to the grave consequences in its harness. Objective: For this reason, anti-HIV agents are imperative, and the search for the same from natural resources would assure the safety. Materials and Methods: In this investigation we have performed molecular docking, molecular property prediction, drug-likeness score, and molecular dynamics (MD) simulation to develop a novel anti-HIV drug. We have screened 12 alkaloids from a medicinal plant Toddalia asiatica for its probabilistic binding with the active site of the HIV-1-reverse transcriptase (HIV-1-RT) domain (the major contributor to the onset of the disease). Results: The docking results were evaluated based on free energies of binding (ΔG), and the results suggested toddanol, toddanone, and toddalenone to be potent inhibitors of HIV-1-RT. In addition, the alkaloids were subjected to molecular property prediction analysis. Toddanol and toddanone with more rotatable bonds were found to have a drug-likeness score of 0.23 and 0.11, respectively. These scores were comparable with the standard anti-HIV drug zidovudine with a model score 0.28. Finally, two characteristic protein-ligand complexes were exposed to MD simulation to determine the stability of the predicted conformations. Conclusion: The toddanol-RT complex showed higher stability and stronger H-bonds than toddanone-RT complex. Based on these observations, we firmly believe that the alkaloid toddanol could aid in efficient HIV-1 drug discovery. SUMMARY In the present study, the molecular docking and MD simulations are performed to explore the possible binding mode of HIV 1 RT with 12 alkaloids of T. asiatica. Molecular docking by AutoDock4 revealed three alkaloids toddanol, toddanone, and toddalenone with highest binding affinity towards HIV 1 RT. The drug likeness model score revealed a positive score for toddanol and toddanone which is comparable to the drug likeness score of the standard anti HIV drug zidovudine. Results from simulation analysis revealed that toddanol RT complex is more stable than toddanone RT complex inferring toddanol as a potential anti HIV drug molecule.

Abstract
BACKGROUND AND AIM Stapling devices are used for pharyngeal closure after laryngectomy for the past few decades although it has not gained wide acceptance. This study is aimed at evaluating the role of stapler in pharyngeal closure after laryngectomy. METHODS Thirty consecutive patients who underwent stapled laryngectomy at our institution from October 2004 to February 2008 were evaluated retrospectively. Linear stapler (Proximate TX 60; Ethicon Inc.) was used for closure of neopharynx. RESULTS There were 28 males and 2 females with mean age of 54.5 years (54.5 ± 11.2). Nineteen of these patients (63.3%) had salvage laryngectomy and two patients (6.7%) had laryngectomy for a second primary tumor. Twenty-eight patients had total laryngectomy (TL), whereas two had extended TL. Eight patients had salivary leak (26.7%). Of these, 6 (75%) had prior radiation. All salivary leaks except one were managed conservatively. Follow-up ranged from 7 to 54 months (median: 21 months). Seven patients (23.3%) developed recurrence, six at the stoma, of which 5 (83.3%) had initial extension of disease to the subglottis. Four-year disease-free survival was 54.4%. CONCLUSION Pharyngeal closure by linear stapler is an efficient and safe method of fashioning the neopharynx after laryngectomy with no added risk of occurrence of pharyngocutaneous fistula in primary and salvage laryngectomies.

Abstract
OBJECTIVE The conformal nature of dose distribution produced by volumetric modulated arc radiotherapy (VMAT) increases the risk of geographic miss. Data regarding patterns of failure after VMAT in oral cavity cancers in resource-constrained settings are scarce. The aim of the present study was to ascertain the patterns of failure in patients receiving adjuvant VMAT intensity-modulated radiotherapy (IMRT) for oral cavity cancer in Malabar Cancer Center, Kerala, India. METHODS Data of patients with oral cavity cancer receiving adjuvant VMAT IMRT between April 2012 and March 2014 were collected. Recurrent volumes were delineated on the treatment planning images and classified as defined by Dawson et al (Dawson LA, Anzai Y, Marsh L, Martel MK, Paulino A, Ship JA, et al. Patterns of local-regional recurrence following parotid-sparing conformal and segmental intensity-modulated radiotherapy for head and neck cancer. Int J Radiat Oncol Biol Phys 2000; 46: 1117-26). RESULTS 75 patients with a median follow-up of 24 months were analysed. 41 (55%) patients had oral tongue cancers and 52 (69%) of the patients had Stage IVA cancers. The 2-year locoregional recurrence-free survival, disease-free survival and overall survival were 88.9%, 82.1% and 80.5%, respectively. With a median time to failure of 6.5 months, five infield and three outfield failures were identified. CONCLUSION A relatively low rate of outfield failure and lack of marginal failure attests to the efficacy of VMAT in such patients. Modifications to our existing target delineation policy have been proposed. ADVANCES IN KNOWLEDGE The use of standardized target delineation methods allows safe use of VMAT IMRT even in resource-constrained settings.

Abstract
Background: Triple negative breast cancers (TNBCs) are a diverse and heterogeneous group of tumors that by definition lack estrogen and progesterone receptors and amplification of the HER-2 gene. The majority of the tumors classified as TNBCs are highly malignant, patients are usually young and only a subgroup of patients responds to conventional chemotherapy with a favorable prognosis. Various studies have been reported in western literature on TNBCs, all highlighting the poor prognosis of this subtype. However, extensive data from India is lacking. Aim: The aim of this study was to analyze the epidemiological and clinical profile of TNBCs at our institute. Materials and Methods: This was the retrospective study carried out in Tertiary Cancer Care Center in South India. Case files of all breast cancer patients were reviewed from the hospital database registered in 1 year and TNBC patients were selected for the study. Patient's characteristic, treatment, and histological features were analyzed. Results: A total of 322 patients were registered during the period of 1 year and 26% (84/322) of total patients were TNBC. Median age of presentation was 44.5 years. About 94% (79/84) of patients had first full-term delivery before the age of 30 years. The most common presenting symptom was left sided breast lump. Locally advanced and early breast cancer (EBC) was 51% (43/84) and 42% (36/84), respectively. Metastatic breast cancer was seen in five patients. The highest numbers of patients were node negative disease (36.9%) [31/84], followed by N1 30.95% (26/84). Most of the patients had high-grade tumor. 94% (34/36) of cases of EBC had undergone upfront modified radical mastectomy. Invasive ductal carcinoma was the predominant histology except one who had medullary carcinoma. Twenty-four patients received neoadjuvant chemotherapy (NACT). There was no pathological complete remission, but all patients responded to NACT. Metastatic disease was seen in five patients. All patients had bone metastasis. Conclusions: TNBCs are highly aggressive subtype, with high grade with limited treatment options and very poor prognosis. Incidence is more in our country than the western literature. Even in our country also the incidence is varies in different region. TNBCs are significantly associated with young aged patients. There was a lack of association between tumor size and lymph node positivity.

Abstract
The immune responses to filarial parasites encompass a complex network of innate and adaptive cells whose interaction with the parasite underlies a spectrum of clinical manifestations. The predominant immunological feature of lymphatic filariasis is an antigen-specific Th2 response and an expansion of IL-10 producing CD4(+) T cells that is accompanied by a muted Th1 response. This antigen-specific T-cell hyporesponsiveness appears to be crucial for the maintenance of the sustained, long-standing infection often with high parasite densities. While the correlates of protective immunity to lymphatic filariasis are still incompletely understood, primarily due to the lack of suitable animal models to study susceptibility, it is clear that T cells and to a certain extent B cells are required for protective immunity. Host immune responses, especially CD4(+) T-cell responses clearly play a role in mediating pathological manifestations of LF, including lymphedema, hydrocele and elephantiasis. The main underlying defect in the development of clinical pathology appears to be a failure to induce T-cell hyporesponsiveness in the face of antigenic stimulation. Finally, another intriguing feature of filarial infections is their propensity to induce bystander effects on a variety of immune responses, including responses to vaccinations, allergens and to other infectious agents. The complexity of the immune response to filarial infection therefore provides an important gateway to understanding the regulation of immune responses to chronic infections, in general.

Abstract
There is a persistent need to assess the effects of TiO2 nanoparticles on the aquatic ecosystem owing to their increasing usage in consumer products and risk of environmental release. The current study is focused on TiO2 nanoparticle-induced acute toxicity at sub-ppm level (≤1ppm) on the three different freshwater sediment bacterial isolates and their consortium under two different irradiation (visible light and dark) conditions. The consortium of the bacterial isolates was found to be less affected by the exposure to the nanoparticles compared to the individual cells. The oxidative stress contributed considerably towards the cytotoxicity under both light and dark conditions. A statistically significant increase in membrane permeability was noted under the dark conditions as compared to the light conditions. The optical and fluorescence microscopic images showed aggregation and chain formation of the bacterial cells, when exposed to the nanoparticles. The electron microscopic (SEM, TEM) observations suggested considerable damage of cells and bio-uptake of nanoparticles. The exopolysaccrides (EPS) production and biofilm formation were noted to increase in the presence of the nanoparticles, and expression of the key genes involved in biofilm formation was studied by RT-PCR.

Abstract
BACKGROUND Recent studies indicate neoadjuvant chemotherapy (NACT) can result in R0 resection in a substantial proportion of patients with technically unresectable oral cavity cancers. However, data regarding the efficacy and safety of docetaxel, cisplatin and 5 fluorouracil (TPF) NACT in our setting is lacking. The present audit was proposed to evaluate the toxicities encountered during administration of this regimen. It was hypothesized that TPF NACT would be considered feasible for routine administration if an average relative dose intensity (ARDI) of ≥0.90 or more in at least 70% of the patients. MATERIALS AND METHODS Technically unresectable oral cancers with Eastern Cooperative Oncology Group PS 0-2, with biopsy proven squamous cell carcinoma underwent two cycles of NACT with TPF regimen. Toxicity and response rates were noted following the CTCAE 4.03 and RECIST criteria. Descriptive analysis of completion rates (completing 2 cycles of planned chemotherapy with ARDI of 0.85 or more), reason for delay, toxicity, and response are presented. RESULTS The NACT was completed by all patients. The number of subjects who completed all planned cycles of chemotherapy are with the ARDI of the delivered chemotherapy been equal to or >0.85 was 11 (91.67%). All toxicity inclusive Grade 3-5 toxicity was seen in 11 patients (91.67%). The response rate of chemotherapy was 83.33%. There were three complete response, seven partial response, and two stable disease seen post NACT in this study. CONCLUSION Docetaxel, cisplatin and 5 fluorouracil regimen can be routinely administered at our center with the supportive care methods and precautionary methods used in our study.

Abstract
Different metal oxide based fluoro-phosphate glasses doped with Sm(3+) ions are investigated using XRD, SEM with EDS, FTIR, Raman spectra, optical absorption and photo-luminescence techniques. These glass matrices have been prepared by conventional melt quenching technique. The glassy nature of the present glass matrices are confirmed by XRD profiles and SEM photographs. The composition of the glasses is checked by EDS. Based on FTIR and Raman spectra, the authors have analyzed functional groups that are present in the glass matrices. Judd-Ofelt intensity parameters, Ωλ (λ=2,4,6) have been evaluated from absorption spectra. Radiative parameters such as radiative transition probabilities (AR), radiative lifetimes (τR), integrated absorption cross sections (Σ) and branching ratios (βR) are calculated using Judd-Ofelt intensity parameters. From the photoluminescence spectra, experimental branching ratios (βexp) and stimulated emission cross-sections (σP) for all the observed emission transitions are calculated. To investigate luminescence potentiality of (4)G5/2→(6)H7/2 emission level of Sm(3+) doped different fluorophosphate glasses, experimental radiative lifetimes (τexp) are obtained from decay curve analysis for all glass matrices. Finally, these observed results are discussed and compared with the literature data.
