Anomalous Evolution of the Near-Side Jet Peak Shape in Pb-Pb Collisions at sqrt[s_{NN}]=2.76 TeV

The measurement of two-particle angular correlations is a powerful tool to study jet quenching in a p_{T} region inaccessible by direct jet identification. In these measurements pseudorapidity (Δη) and azimuthal (Δφ) differences are used to extract the shape of the near-side peak formed by particles associated with a higher p_{T} trigger particle (1<p_{T,trig}<8  GeV/c). A combined fit of the near-side peak and long-range correlations is applied to the data allowing the extraction of the centrality evolution of the peak shape in Pb-Pb collisions at sqrt[s_{NN}]=2.76  TeV. A significant broadening of the peak in the Δη direction at low p_{T} is found from peripheral to central collisions, which vanishes above 4  GeV/c, while in the Δφ direction the peak is almost independent of centrality. For the 10% most central collisions and 1<p_{T,assoc}<2  GeV/c, 1<p_{T,trig}<3  GeV/c a novel feature is observed: a depletion develops around the center of the peak. The results are compared to pp collisions at the same center of mass energy and ampt model simulations. The comparison to the investigated models suggests that the broadening and the development of the depletion is connected to the strength of radial and longitudinal flow.

Ramsay Hunt Syndrome: A Diagnostic Challenge for General Dental Practitioners

Ramsay hunt syndrome is not just a syndrome but it's rather an infectious disease caused by reactivation of latent varicella-zoster virus in geniculate ganglion. This was first explained by J. Ramsay Hunt as a triad of complications like otalgia, mucosal and cutaneous rashes with or without trigeminal facial palsy. The facial palsy can occur with characteristic vesicles along the path of nerve. We present a case of Ramsay Hunt syndrome in a 48-year-old male. The unilateral pattern of facial involvement and presence of vesicles assisted us for early diagnosis, distinguishing the syndrome with diseases mimicking other severe neurological illnesses and prompt treatment.

A pragmatic randomised controlled trial comparing the efficacy of a femoral nerve block and periarticular infiltration for early pain relief following total knee arthroplasty

AIMS

The aim of this study was to compare the effectiveness of a femoral nerve block and a periarticular infiltration in the management of early post-operative pain after total knee arthroplasty (TKA).

PATIENTS AND METHODS

A pragmatic, single centre, two arm parallel group, patient blinded, randomised controlled trial was undertaken. All patients due for TKA were eligible. Exclusion criteria included contraindications to the medications involved in the study and patients with a neurological abnormality of the lower limb. Patients received either a femoral nerve block with 75 mg of 0.25% levobupivacaine hydrochloride around the nerve, or periarticular infiltration with 150 mg of 0.25% levobupivacaine hydrochloride, 10 mg morphine sulphate, 30 mg ketorolac trometamol and 0.25 mg of adrenaline all diluted with 0.9% saline to make a volume of 150 ml.

RESULTS

A total of 264 patients were recruited and data from 230 (88%) were available for the primary analysis. Intention-to-treat analysis of the primary outcome measure of a visual analogue score for pain on the first post-operative day, prior to physiotherapy, was similar in both groups. The mean difference was -0.7 (95% confidence interval (CI) -5.9 to 4.5; p = 0.834). The periarticular group used less morphine in the first post-operative day compared with the femoral nerve block group (74%, 95% CI 55 to 99). The femoral nerve block group reported 39 adverse events, of which 27 were serious, in 31 patients and the periarticular group reported 51 adverse events, of which 38 were serious, in 42 patients up to six weeks post-operatively. None of the adverse events were directly attributed to either of the interventions under investigation.

CONCLUSION

Periarticular infiltration is a viable and safe alternative to femoral nerve block for the early post-operative relief of pain following TKA. Cite this article: Bone Joint J 2017;99-B:904-11.

Pattern of care in operable endometrial cancer treated at a rural-based tertiary care cancer center

PURPOSE

An audit was planned to study the demographics, staging, treatment details, and outcomes of operable endometrial cancers.

METHODOLOGY

All operable endometrial cancers treated between January 2009 and October 2014 were included in the study. The details regarding demographics, staging, surgical procedure, pathological staging, adjuvant treatment, and outcomes were extracted from the case records. Descriptive statistics was performed. The time-to-event analysis was done by Kaplan-Meier method. Univariate and multivariate analyses were done for disease-free survival (DFS) and overall survival (OS).

RESULTS

There were 55 patients with a median age of 59 years (35-73 years). The Eastern Cooperative Oncology Group performance status was 1 in 52 patients (94.5%) and 2 in 3 patients (5.5%). Forty-nine patients (89.1%) had disease restricted to endometrium while 6 patients (10.9%) had cervical involvement. The surgery done was Type I hysterectomy in 49 patients (89.1%), Type II in 5 patients (9.1%), and Type III in 1 patient (1.8%). Pelvic lymph node dissection was done in all patients while para-aortic (infrahilar) dissection was done in 48 patients (87.3%). The pathological stages were Stage IA in 19 patients, Stage IB in 15 patients, Stage II in 4 patients, Stage IIIA in 3 patients, Stage IIIB in 2 patients, Stage IIIC1 in 5 patients, Stage IIIC2 in 4 patients, and Stage IV in 3 patients. Grade 1 tumors were seen in 23 patients, Grade 2 in 13 patients, and Grade 3 in 19 patients. The histology was endometrioid in 44 patients, serous in 6 patients, clear cell in 3 patients, and others in 2 patients. Adjuvant treatment was received by 40 patients. With a median follow-up of 2.5 years, the 3-year DFS and OS were 78% and 82%, respectively. Age >59 years, Stage III or greater, and Grade 3 tumors were independent prognostic factors adversely affecting both DFS and OS.

CONCLUSION

The outcomes in our study are comparable to that seen in Western literature. Elderly status, higher stage, and a poorly differentiated tumor are associated with poor outcomes.

Measurement of azimuthal correlations of D mesons with charged particles in pp collisions at [Formula: see text] TeV and p-Pb collisions at [Formula: see text] TeV

The azimuthal correlations of D mesons with charged particles were measured with the ALICE apparatus in pp collisions at [Formula: see text] and p-Pb collisions at [Formula: see text] at the Large Hadron Collider. [Formula: see text], [Formula: see text], and [Formula: see text] mesons and their charge conjugates with transverse momentum [Formula: see text] and rapidity in the nucleon-nucleon centre-of-mass system [Formula: see text] (pp collisions) and [Formula: see text] (p-Pb collisions) were correlated to charged particles with [Formula: see text]. The yield of charged particles in the correlation peak induced by the jet containing the D meson and the peak width are compatible within uncertainties in the two collision systems. The data are described within uncertainties by Monte-Carlo simulations based on PYTHIA, POWHEG, and EPOS 3 event generators.

Postharvest Processing and Benefits of Black Pepper, Coriander, Cinnamon, Fenugreek, and Turmeric Spices

Spices are prime source for flavor, aroma, and taste in cuisines and play an active role as medicines due to their high antioxidant properties. As medicine or food, the importance of spices cannot be overemphasized. The medicinal values of spices are very well established in treating various ailments like cancer, fever, malaria, stomach offset, nausea, and many more. A spice may be available in several forms: fresh, whole dried, or pre-ground dried which requires further processing to be utilized in the form of value-added product. This review paper deals with the cultivation, postharvesting, chemical composition, uses, health, and medicinal benefits of the selected spice viz., black pepper, coriander, cinnamon, fenugreek, turmeric, and technological advances in processing of spices viz., super critical fluid extraction, cryogenic grinding, and microencapsulation etc. This paper also focuses on issues related to utilization of spices toward its high end-product development and characterization in pharmaceuticals and other medicinal purposes. The availability of different spices and their varietal differences and location have their pertinent characters, which are much demanding to refine postharvest and processing to assure its quality in the international market.

Synthesis and biophysical analysis of modified thymine-containing DNA oligonucleotides

We report the synthesis of a 5-formyl-2'-deoxyuridine (5fU) phosphoramidite and the preparation of oligonucleotides comprising all known, naturally observed eukaryotic thymidine modifications. Biophysical characterization of the synthetic oligonucleotides indicates that 5fU, but not the other T-derivatives, can alter DNA structures.

Tolerance of weekly paclitaxel and carboplatin as neoadjuvant chemotherapy in advanced ovarian cancer patients who are unlikely to tolerate 3 weekly paclitaxel and carboplatin

OBJECTIVE

There are little data regarding safety and effectiveness of neoadjuvant chemotherapy (NACT) in patients who are considered unfit for receiving 3 weekly paclitaxel and carboplatin. The aim of this study was to study the toxicity and response rates of weekly paclitaxel and carboplatin as NACT in such cohort of patients.

METHODS

Study population included advanced ovarian cancer patients who were unlikely to tolerate 3 weekly paclitaxel and carboplatin and hence received weekly paclitaxel (80 mg/m2) and carboplatin AUC-2 as NACT. The data regarding the baseline characteristics, chemotherapy tolerance, completion rates, toxicity (CTCAE version 4.02), and radiological response rates are presented. SPSS version 16 was used for analysis. Descriptive statistics is presented.

RESULT

Eleven patients received this schedule. Nine patients completed nine cycles of NACT. Except one, all patients completed NACT with an average relative dose intensity of >0.8. There was no chemotherapy-related mortality. Grade 3-4 life-threatening complications were seen in two patients. The post NACT response rate was 100%.

CONCLUSION

Weekly paclitaxel and carboplatin chemotherapy is safe and efficacious in patients who are unsuitable for 3 weekly paclitaxel and carboplatin chemotherapy schedules.

An audit of cytoreductive surgeries in ovarian cancer from a rural based cancer center

BACKGROUND AND OBJECTIVE

Ovarian cancers are frequently seen at an advanced stage in our center. This audit was planned to see the morbidity and efficacy of different types of cytoreductive surgeries (radical vs. ultra-radical) done in such patients.

METHODS

This was a retrospective analysis of all ovarian cancer patients who underwent cytoreductive surgery at our center from January 2009 to August 2013. The case records of these patients were reviewed and the demographic, disease-related and treatment-related data were extracted.

RESULTS

Fifty-fivepatients were identified. Ten (18.2%) patients underwent primary cytoreduction while 45 patients had (81.8%) interval cytoreduction. The resections achieved were optimal in 50 patients (90.9%) and suboptimal in five patients (9.1%). The postoperative median blood loss was 400 (350-600) mL. The median time interval for surgery was 4.0 h (3-5 h). The type of resection achieved (optimal vs. suboptimal) was the only factor affecting the progression free survival (PFS) (Hazard ratio = 0.08 95% confidence interval 0.02-0.3). There was no significant difference in postoperative morbidity in patients undergoing the ultra-radical surgery as compared to those who underwent radical surgery.

CONCLUSION

Optimal cytoreduction may improve PFS in advanced ovarian cancer patients and needs to be done even if it mandates an ultra-radical surgery.

Impact of Malnutrition, Inflammation, and Atherosclerosis on the Outcome in Hemodialysis Patients

Malnutrition, inflammation, and atherosclerosis are significant problems in patients on hemodialysis. A prospective, observational study in 100 hemodialysis patients for 2 years was conducted. The primary outcomes were hospitalizations and mortality at the end of 2 years. The mean age was 61 ± 11.3 years and 69% were male. Seven patients did not complete the study (five underwent transplant and two were shifted to other units). Serum albumin was significantly lower in malnourished patients at 6 months from the beginning of the study period (3.58 vs. 3.79 g/dl, P = 0.001). Malnutrition based on subjective global assessment (SGA) was seen in 30 (32%) patients: mild to moderate in 27 (29%) and severe in 3 (3%). Inflammation was seen in 73 (78.5%) patients and intimal-medial thickness of >1.1 mm indicating significant atherosclerosis was seen in 73 (78.5%) patients. Modified SGA score and malnutrition-inflammation score (MIS) were significantly more in the malnourished group. Statistically significant association was seen between hospitalization and mortality in the malnourished population, and the odds ratio of death in malnourished patients was 9.83 (95% confidence interval: 2.8-34.3, P < 0.001). There was a moderate correlation between malnutrition assessed by modified SGA and MIS score (r = 0.54, P < 0.001). Mortality rate was 37% in patients with mild to moderate and 67% in severe malnutrition. Hospital admission was seen in 43 (46%) patients and was significantly more common in malnourished compared to well-nourished patients (77% vs. 32%, P < 0.001). Multiple logistic regression analysis showed that malnutrition by Modified SGA was the only significant variable associated with mortality at 2 years, and addition of MIS score did not improve the predictive ability of the model to modified SGA. We recommend the use of modified SGA and serial serum albumin to monitor nutrition in hemodialysis patients.

Head and neck cancer in geriatric patients: Analysis of the pattern of care given at a tertiary cancer care center

BACKGROUND AND AIM

The percentage of elderly people with head and neck cancers (HNC) is on the rise. This makes HNC in this group of patients an important issue for healthcare providers. The present study was planned to analyze the patterns of care given to the geriatric patients and to identify the factors influencing the decision making process.

MATERIALS AND METHODS

Data of all the elderly patients (≥65 years) registered in the year 2012, with histologically proven HNC (all sites, stages, histopathological types, except lymphoma, sarcoma and cervical metastasis of unknown origin) receiving treatment (definitive/palliative) were collected.

RESULTS

A total of 270 patients were included in this study. The median age was 72 years (range: 65-101), with predominant male population (70%, n = 190). Oral cavity squamous cell carcinoma (SCC) was the most common cancer (57%, n = 154). Eastern Co-Operative Oncology Group performance status (PS) of 0-2 was seen in 91% of the patients. Co-morbidities were present in 139 (51.5%) patients. 50% (n = 134) of the patients received palliative intent treatment, 45% (n = 123) definitive treatment, whereas in 5% (n = 13) the intent was not mentioned. Age, a clinical stage and PS significantly influenced the decision making on the intent of treatment. 208 (77%) patients completed their treatment irrespective of the intent. Age was the only factor influencing treatment completion irrespective of the intent.

CONCLUSION

Geriatric HNC patients frequently present with advanced disease, having multiple co-morbidities. Hence, a multidisciplinary team management of these patients is essential, also taking into account of the social and financial support available to these patients.

Correlated Event-by-Event Fluctuations of Flow Harmonics in Pb-Pb Collisions at sqrt[s_{NN}]=2.76 TeV

We report the measurements of correlations between event-by-event fluctuations of amplitudes of anisotropic flow harmonics in nucleus-nucleus collisions, obtained for the first time using a new analysis method based on multiparticle cumulants in mixed harmonics. This novel method is robust against systematic biases originating from nonflow effects and by construction any dependence on symmetry planes is eliminated. We demonstrate that correlations of flow harmonics exhibit a better sensitivity to medium properties than the individual flow harmonics. The new measurements are performed in Pb-Pb collisions at the center-of-mass energy per nucleon pair of sqrt[s_{NN}]=2.76  TeV by the ALICE experiment at the Large Hadron Collider. The centrality dependence of correlation between event-by-event fluctuations of the elliptic v_{2} and quadrangular v_{4} flow harmonics, as well as of anticorrelation between v_{2} and triangular v_{3} flow harmonics are presented. The results cover two different regimes of the initial state configurations: geometry dominated (in midcentral collisions) and fluctuation dominated (in the most central collisions). Comparisons are made to predictions from Monte Carlo Glauber, viscous hydrodynamics, ampt, and hijing models. Together with the existing measurements of the individual flow harmonics the presented results provide further constraints on the initial conditions and the transport properties of the system produced in heavy-ion collisions.

Tolerance of weekly metronomic paclitaxel and carboplatin as neoadjuvant chemotherapy in advanced ovarian cancer patients who are unlikely to tolerate 3 weekly paclitaxel and carboplatin

OBJECTIVE

There are little data regarding safety and effectiveness of neoadjuvant chemotherapy (NACT) in patients who are considered unfit for receiving 3 weekly paclitaxel and carboplatin. The aim of this study was to examine the toxicity and response rates of weekly paclitaxel and carboplatin as NACT in such cohort of patients.

METHODS

Study population included advanced ovarian cancer patients who were unlikely to tolerate 3 weekly paclitaxel and carboplatin and hence received weekly paclitaxel (80 mg/m(2)) and carboplatin AUC-2 as NACT. The data regarding the baseline characteristics, chemotherapy tolerance, completion rates, toxicity (Common Terminology Criteria for Adverse Events version 4.02), and radiological response rates are presented. SPSS version 16 was used for analysis. Descriptive statistics is presented.

RESULTS

Eleven patients received this schedule. Nine patients completed nine cycles of NACT. Except one, all patients completed NACT with an average relative dose intensity of >0.8. There was no chemotherapy-related mortality. Grade 3-4 life-threatening complications were seen in two patients. The post NACT response rate was 100%.

CONCLUSIONS

Weekly paclitaxel and carboplatin chemotherapy is safe and efficacious in patients who are unsuitable for 3 weekly paclitaxel and carboplatin chemotherapy schedules.

Centrality Dependence of the Charged-Particle Multiplicity Density at Midrapidity in Pb-Pb Collisions at sqrt[s_{NN}]=5.02 TeV

The pseudorapidity density of charged particles, dN_{ch}/dη, at midrapidity in Pb-Pb collisions has been measured at a center-of-mass energy per nucleon pair of sqrt[s_{NN}]=5.02  TeV. For the 5% most central collisions, we measure a value of 1943±54. The rise in dN_{ch}/dη as a function of sqrt[s_{NN}] is steeper than that observed in proton-proton collisions and follows the trend established by measurements at lower energy. The increase of dN_{ch}/dη as a function of the average number of participant nucleons, ⟨N_{part}⟩, calculated in a Glauber model, is compared with the previous measurement at sqrt[s_{NN}]=2.76  TeV. A constant factor of about 1.2 describes the increase in dN_{ch}/dη from sqrt[s_{NN}]=2.76 to 5.02 TeV for all centrality classes, within the measured range of 0%-80% centrality. The results are also compared to models based on different mechanisms for particle production in nuclear collisions.

Genome-wide association analyses reveal complex genetic architecture underlying natural variation for flowering time in canola

Optimum flowering time is the key to maximize canola production in order to meet global demand of vegetable oil, biodiesel and canola-meal. We reveal extensive variation in flowering time across diverse genotypes of canola under field, glasshouse and controlled environmental conditions. We conduct a genome-wide association study and identify 69 single nucleotide polymorphism (SNP) markers associated with flowering time, which are repeatedly detected across experiments. Several associated SNPs occur in clusters across the canola genome; seven of them were detected within 20 Kb regions of a priori candidate genes; FLOWERING LOCUS T, FRUITFUL, FLOWERING LOCUS C, CONSTANS, FRIGIDA, PHYTOCHROME B and an additional five SNPs were localized within 14 Kb of a previously identified quantitative trait loci for flowering time. Expression analyses showed that among FLC paralogs, BnFLC.A2 accounts for ~23% of natural variation in diverse accessions. Genome-wide association analysis for FLC expression levels mapped not only BnFLC.C2 but also other loci that contribute to variation in FLC expression. In addition to revealing the complex genetic architecture of flowering time variation, we demonstrate that the identified SNPs can be modelled to predict flowering time in diverse canola germplasm accurately and hence are suitable for genomic selection of adaptative traits in canola improvement programmes.

Centrality dependence of charged jet production in p-Pb collisions at [Formula: see text] = 5.02 TeV

Measurements of charged jet production as a function of centrality are presented for  p-Pb  collisions recorded at [Formula: see text] TeV with the ALICE detector. Centrality classes are determined via the energy deposit in neutron calorimeters at zero degree, close to the beam direction, to minimise dynamical biases of the selection. The corresponding number of participants or binary nucleon-nucleon collisions is determined based on the particle production in the Pb-going rapidity region. Jets have been reconstructed in the central rapidity region from charged particles with the anti-[Formula: see text] algorithm for resolution parameters [Formula: see text] and [Formula: see text] in the transverse momentum range 20 to 120 GeV/c. The reconstructed jet momentum and yields have been corrected for detector effects and underlying-event background. In the five centrality bins considered, the charged jet production in  p-Pb   collisions is consistent with the production expected from binary scaling from pp collisions. The ratio of jet yields reconstructed with the two different resolution parameters is also independent of the centrality selection, demonstrating the absence of major modifications of the radial jet structure in the reported centrality classes.

A facile one-pot synthesis of novel steroidal dispiro-indenoquinoxaline pyrrolidines via multicomponent-[3+2]-cycloaddition of azomethine ylides in ionic liquid is described. The structure of cycloadduct is confirmed by IR, (1)H NMR, (13)C NMR, high resolution mass spectroscopy and elemental analysis.

Production of K[Formula: see text](892)[Formula: see text] and [Formula: see text](1020) in p-Pb collisions at [Formula: see text] = 5.02 TeV

The production of K[Formula: see text](892)[Formula: see text] and [Formula: see text](1020) mesons has been measured in p-Pb collisions at [Formula: see text][Formula: see text] 5.02 TeV. K[Formula: see text] and [Formula: see text] are reconstructed via their decay into charged hadrons with the ALICE detector in the rapidity range [Formula: see text]. The transverse momentum spectra, measured as a function of the multiplicity, have a p[Formula: see text] range from 0 to 15 GeV/c for K[Formula: see text] and from 0.3 to 21 GeV/c for [Formula: see text]. Integrated yields, mean transverse momenta and particle ratios are reported and compared with results in pp collisions at [Formula: see text][Formula: see text] 7 TeV and Pb-Pb collisions at [Formula: see text][Formula: see text] 2.76 TeV. In Pb-Pb and p-Pb collisions, K[Formula: see text] and [Formula: see text] probe the hadronic phase of the system and contribute to the study of particle formation mechanisms by comparison with other identified hadrons. For this purpose, the mean transverse momenta and the differential proton-to-[Formula: see text] ratio are discussed as a function of the multiplicity of the event. The short-lived K[Formula: see text] is measured to investigate re-scattering effects, believed to be related to the size of the system and to the lifetime of the hadronic phase.

Anisotropic Flow of Charged Particles in Pb-Pb Collisions at √[s{NN}]=5.02 TeV

We report the first results of elliptic (v_{2}), triangular (v_{3}), and quadrangular (v_{4}) flow of charged particles in Pb-Pb collisions at a center-of-mass energy per nucleon pair of sqrt[s_{NN}]=5.02  TeV with the ALICE detector at the CERN Large Hadron Collider. The measurements are performed in the central pseudorapidity region |η|<0.8 and for the transverse momentum range 0.2<p_{T}<5  GeV/c. The anisotropic flow is measured using two-particle correlations with a pseudorapidity gap greater than one unit and with the multiparticle cumulant method. Compared to results from Pb-Pb collisions at sqrt[s_{NN}]=2.76  TeV, the anisotropic flow coefficients v_{2}, v_{3}, and v_{4} are found to increase by (3.0±0.6)%, (4.3±1.4)%, and (10.2±3.8)%, respectively, in the centrality range 0%-50%. This increase can be attributed mostly to an increase of the average transverse momentum between the two energies. The measurements are found to be compatible with hydrodynamic model calculations. This comparison provides a unique opportunity to test the validity of the hydrodynamic picture and the power to further discriminate between various possibilities for the temperature dependence of shear viscosity to entropy density ratio of the produced matter in heavy-ion collisions at the highest energies.

Protocol for a single-centre randomised controlled trial of multimodal periarticular anaesthetic infiltration versus single-agent femoral nerve blockade as analgesia for total knee arthroplasty: Perioperative Analgesia for Knee Arthroplasty (PAKA)

INTRODUCTION

Total knee arthroplasty (TKA) surgery causes postoperative pain. The use of perioperative injections around the knee containing local anaesthetic, opiates and non-steroidal anti-inflammatory drugs has increased in popularity to manage pain. Theoretical advantages include reduced requirements for analgesia and earlier mobilisation. We propose a single-centre randomised controlled trial of multimodal periarticular anaesthetic infiltration versus femoral nerve anaesthetic blockade as analgesia for TKA. The aim is to determine, in patients undergoing TKA, if there is a difference in patient-reported pain scores on the visual analogue scale (VAS) prior to physiotherapy on day 1 postoperatively between treatment groups.

METHODS AND ANALYSIS

Patients undergoing a primary unilateral TKA at University Hospitals Coventry and Warwickshire Hospitals will be assessed for eligibility. A total of 264 patients will provide 90% power to detect a difference of 12 mm on the VAS on day 1 postoperatively at the 5% level. The trial will use 1:1 randomisation, stratified by mode of anaesthetic. Primary outcome measure will be the VAS for pain prior to physiotherapy on day 1. Secondary outcome measures include VAS on day 2, total use of opiate analgesia up to 48 h, ordinal pain scores up to 40 min after surgery, independent functional knee physiotherapist assessment on days 1 and 2. Oxford knee Scores (OKS), EuroQol (EQ-5D) and Douleur Neuropathic Pain Scores (DN2) will be recorded at baseline, 6 weeks and 12 months. Adverse events will be recorded up to 12 months. Analysis will investigate differences in VAS on day 1 between the two treatment groups on an intention-to-treat basis. Tests will be two-sided and considered to provide evidence for a significant difference if p values are less than 0.05.

Charge-transfer complexation between naphthalene diimides and aromatic solvents

Naphthalene diimides (NDIs) form emissive ground-state charge-transfer (CT) complexes with various electron rich aromatic solvents like benzene, o-xylene and mesitylene. TD-DFT calculation of the complexes suggests CT interaction and accounts for the observed ground-state changes.

G-quadruplex ligands exhibit differential G-tetrad selectivity

A rapid and simple equilibrium-binding assay mediated by ligand-induced fluorescence quenching of fluorophore-labelled G-quadruplex (G4) structures enabled quantitative interrogation of mutually exclusive ligand binding interactions at opposed G-tetrads. This technique revealed that the ligands TmPyP4, PhenDC3, and PDS have differential chemotype-specific binding preferences for individual G-tetrads of a model genomic G4 structure.

Plant based butters

During the last few years the popularity for the plant based butters (nut and seed butters) has increased considerably. Earlier peanut butter was the only alternative to the dairy butter, but over the years development in the technologies and also the consumer awareness about the plant based butters, has led the development of myriad varieties of butters with different nuts and seeds, which are very good source of protein, fiber, essential fatty acids and other nutrients. These days' different varieties of plant based butters are available in the market viz., peanut butter, soy butter, almond butter, pistachio butter, cashew butter and sesame butter etc. The form of butter is one of the healthy way of integrating nuts and seeds in to our regular diet. Nut and seed butters are generally prepared by roasting, grinding and refrigerated to consume it when it is still fresh. During this process it is imperative to retain the nutritional properties of these nuts and seeds in order to reap the benefits of the fresh nuts and seeds in the form of butter as well. Proper care is needed to minimize the conversion of healthful components in to unhealthy components during processing and further storage. Roasting temperature, temperatures during grinding and storage are the vital factors to be considered in order to have healthy and nutritious plant based butters. In this article, different plant based butters and their processing methods have been described.

Tolerance and toxicity of neoadjuvant docetaxel, cisplatin and 5 fluorouracil regimen in technically unresectable oral cancer in resource limited rural based tertiary cancer center

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.
