Abstract
In the solution treated state Ni-Cr-Mo based alloys exhibit short-range order characterized by the appearance of diffuse intensity spots in electron diffraction patterns at {1 ½ 0} positions. This short-range order appears due to of the formation of chemical heterogeneities. In the present work we report on the investigation of short-range order in Ni-33 at% Cr and Ni-16.7 at% Cr-16.7 at% Mo alloys using transmission electron microscopy. Chemical heterogeneities and their sizes are analyzed by statistical methods applied to three-dimensional atom probe data obtained on the same alloys. The obtained chemical heterogeneities are correlated to regions of short-range order in Ni-33 at% Cr and Ni-16.7 at% Cr-16.7 at% Mo alloys.

Abstract
PURPOSE Paraumbilical hernia (PUH) is a common condition that usually requires surgical repair. However, there is a dearth of literature on this surgery performed under local anaesthesia (LA) without the use of sedation. The aims of this study were to assess peri-operative pain and patient satisfaction in patients undergoing PUH repair using LA without sedation. METHODS All patients having PUH repair under a single consultant between January 2010 and December 2011 were eligible to participate. If eligible for both, patients chose either general anaesthetic (GA) or LA repair. If only eligible for either LA or GA, they were offered this anaesthetic modality. Visual analogue scales were used to report peri-operative pain (10 point score) and satisfaction (%). Results were compared by grade of surgeon (higher surgical trainee (HST) versus consultant). RESULTS A total of 63 patients underwent PUH repair (31 GA; 32 LA). Of them, only 28/32 of LA repair patients agreed to participate. LA and GA patients had equivalent age and sex distribution. LA patients had a lower body mass index (BMI) than GA [27.1 (3.7) versus 30.3 (5.1), p = 0.007]. The median length of LA procedure was 24 (17.5-30) minutes. The median LA solution infiltrated was 25 (20-32) ml. Peri-operative pain scores were low [1.1 (0.3-2.9) %] and patient satisfaction was high [96 (91-99) %]. There were no differences in pain, patient satisfaction, duration of procedure and amount of LA infiltrated with increasing BMI. Comparing HST to consultant, the former took longer [30 (25-36) versus 20 (16-24) minutes, p = 0.0007], infiltrated more LA [34.5 (26-47) versus 20 (19-25.5) ml, p = 0.0039], and patients reported more pain [2.75 (1.0-4.95) versus 0.4 (0.2-1.7) %, p = 0.029], but overall satisfaction was equivalent [95.5 (89-99.25) versus 96.3 (92.25-99) %, p = 0.684]. CONCLUSION Open mesh PUH repair using LA without sedation is associated with low peri-operative pain and very high satisfaction when either a higher surgical trainee or a consultant grade is operating.

Abstract
BACKGROUND AND PURPOSE Head and neck squamous cell carcinoma tumors positive for laboratory biomarkers hrHPV and p16 and negative for EGFR often respond better to nonsurgical organ-preservation therapy than hrHPV-negative, p16-negative, and EGFR overexpressing tumors. CTP has been shown to distinguish which locally advanced head and neck squamous cell carcinomas will respond to induction chemotherapy or chemoradiation. Our purpose was to determine whether a relationship exists between CTP measures and the expression of these laboratory biomarkers, because both appear to separate head and neck squamous cell carcinoma tumors into similar groups. MATERIALS AND METHODS We conducted an institutional review board-approved, Health Insurance Portability and Accountability Act-compliant retrospective review of head and neck CTP in 25 patients with locally advanced head and neck squamous cell carcinoma who had signed informed consent. Eight women and 17 men, 41-80 years of age, constituted a pretreatment group of 18 patients and a palliative group of 7 patients. Tumor biopsy samples were analyzed for overexpression of hrHPV, p16, and EGFR. The hrHPV, p16, and EGFR status of the tumors was correlated with CTP parameters (MTT, BV, BF, CP) by using the Wilcoxon evaluation and Fischer exact test. RESULTS There were significantly lower CP values in pretreatment tumors overexpressing EGFR (P = .04). CP values ≤17.23 were significantly correlated with EGFR overexpression (P = .015). A trend toward higher CP values was present in hrHPV-positive and p16-overexpressing pretreatment tumors (P = .14). CONCLUSIONS A significant correlation exists between CTP measures and EGFR overexpression in head and neck squamous cell carcinomas, suggesting an association between certain imaging findings and molecular biomarkers. These results may be related to a tumor cell survival mechanism linking perfusion and biomarker expression.

Abstract
Diabetic retinopathy (DR) is one of the most debilitating disorders of microvasculature of the retina and one of the leading causes of vision loss among the working class worldwide. At present, intravitreal anti-inflammatory (corticosteroids) and anti-angiogenesis (anti-Vascular Endothelial Growth Factor) agents are being used as wide options for the pharmacotherapy of DR and diabetic macular edema (DME). Anti-inflammatory agents (Triamcinolone acetonide and other agents) have shown evidence-based clinical benefits in various randomized clinical trials for the treatment of DR and DME, and also shown improvement in best corrected visual acuity. However, direct intravitreal injections are associated with serious side-effects like cataract and elevation of Intra Ocular Pressure. Despite this, corticosteroid therapy has been effective for DR and DME, therefore current focus is on the development of novel intravitreal steroid delivery devices that release a small quantity over a prolonged period of time. In addition to corticosteroids, anti-angiogenic agents are found to be effective for the treatment of DR and DME. The most popular target of these agents is the subfamily of proteins known as VEGF, whose over-expression is believed to play a role in numerous diseases including DR and Age-related Macular Degeneration. Intravitreal bevacizumab (Avastin®) and Ranibizumab (Lucentis®) are gaining popularity as a clinical adjunct to panretinal photocoagulation in patients with proliferative DR. Moreover, Lucentis has been recently approved by the United States Food and Drug Administration for macular edema following retinal vein occlusion. Further, systemic agents (specially, hypoglycemic, hypolipidemic and anti-hypertensive agents) have shown beneficial results in reducing the progression of DR. In conclusion, it can be stated that for the present scenario systematic use of available pharmacotherapy as an adjunct to laser photocoagulation, which is gold standard therapy, can be a useful tool in the prevention of vision loss from DR and related disorders. This article summarizes the up-to-date developments in the pharmacotherapy of DR. Method- Literature search was done on online database, Pubmed, Google Scholar, clinitrials.gov and browsing through individual ophthalmology journals and leading pharmaceutical company websites.

Abstract
Influenza A virus genome segment 7 encodes protein M1, which is the matrix protein playing crucial role in the virus life cycle. Any antiviral strategy that aims at reducing, in particular, the expression of this genome segment should, in principle, reduce the infectivity of the virus. We developed a specific antiviral approach at the molecular level and designed several novel 10-23 DNAzymes (Dz) and hammerhead ribozymes (Rz), specifically targeted to cleave at the conserved domains of the influenza virus M1 RNA. We sought to use antisense molecules with the hope that it will facilitate the ribozyme-mediated cleavage. We observed that the Mg(2+)-dependent sequence-specific cleavage of M1 RNA was achieved by both the Dz and Rz in a dose-dependent manner. This combination of catalytic Dz and Rz with antisense molecules, in principle, resulted in more effective gene suppression, inhibited the whole virus replication in host cell, and thus could be exploited for therapeutic purposes.

Abstract
Hyalomma anatolicum anatolicum and Rhipicephalus (Boophilus) microplus are the most economically important tick species in India and other tropical and subtropical regions of the world and transmit pathogens causing animal and human diseases. We demonstrated that vaccination of animal by rHaa86 could be used for the control of both H. a. anatolicum and R. (B.) microplus infestations. By comparing the efficacy of rHaa86 and rBm86, it was observed that vaccine based on rHaa86 will be more effective in controlling homologous challenge infestations (68·7% against larvae and 45·8% against adults). The results of this trial demonstrated that species-specific antigens are the better choice for vaccine development and could serve as an effective tool for the integrated control of H. a. anatolicum.

Abstract
BACKGROUND There is no randomized controlled trial (RCT) evaluating the efficacy and safety of low molecular weight heparin (LMWH) compared to unfractionated heparin (UFH) in cerebral venous sinus thrombosis (CVST). In this RCT, we have evaluated the efficacy and safety of LMWH versus UFH in CVST. METHODS Consecutive patients with CVST diagnosed on the basis of MR venography (MRV) who was free of bleeding diathesis, malignancy, hepatic or renal failure were prospectively enrolled. History, clinical findings and risk factors were evaluated. MRI and MRV findings were recorded. The patients were randomized to LMWH and UFH groups for 14 days followed by oral anticoagulant. The hospital mortality and 3 months outcome as assessed by Barthel index (BI) score were noted. RESULTS 32 patients received UFH and 34 received LMWH. The baseline demographic, clinical and radiological parameters were similar in both the groups. Six patients died and all were in UFH group (P = 0.01). At 3 months, insignificantly higher number of patients recovered completely in LMWH compared to UFH group (30 vs. 20). There was no serious side effect needing withdrawal of drugs except one was withdrawn from UFH because of heparin-induced thrombosis. CONCLUSION Low molecular weight heparin resulted in significantly lower hospital mortality in CVST compared to UFH.

Abstract
Growth modification is under investigation to treat pediatric spine deformities. A hemiepiphyseal staple construct has been shown to alter growth and create physeal structural gradients in an in vivo porcine model. A finite element model (FEM) of a motion segment with and without implant was developed based on preliminary experimental results of initial post-operative motion segment compressive properties. The nonlinear tangent stiffness determined from the model correlated well with the experiments for the native segment, whereas after addition of the implant, the model overestimated the stiffness. The current purpose was to determine the effect of implant-bone contact conditions and initial disc displacement conditions, include growth effects, and compare FEM and experimental results at each stage. A 3D FEM was developed from a CT scan of a porcine T7-T8 segment. The annulus was modeled as an incompressible anisotropic hyperelastic material, and the nucleus as an incompressible fluid. A CAD model of the implant was constructed. Load-displacement curves in compression were determined from a nonlinear analysis performed under different initial and bone-implant interface conditions. Contact conditions were a) perfect, b) friction of 0.1-0.3, or c) soft contact. Initial conditions were that implant insertion induced a) no change in stress or strain in the disc, b) a 2˚ angulation with a centrally located neutral axis and no residual stresses, and c) both stress and coronal plane displacement gradients. Growth modulation effects were added using a published linear relationship between compressive stress and growth rate. A 2 month PO time was simulated. Altering bone - implant surface contact conditions from perfect to either friction or soft contact decreased the stiffness, but all models remained stiffer than experimental results. An initial disc angulation without residual stress did not affect stiffness, whereas stiffness increased with an initial angle and compressive stress. The growth simulation results predicted 32% of control growth on the side ipsilateral to the implant and 81% on the contralateral side. Reductions in growth were similar in pattern, but overestimated, experimental histomorphometric changes.

Abstract
PURPOSE The objective was to analyze the peripheral and inner border lengths of the medial and lateral menisci and the distance between anterior and posterior horns. MATERIALS AND METHODS The menisci from 23 adult knee joints (46 menisci) of the formalin fixed cadaver lower limbs were used. The peripheral and inner borer lengths of the menisci were measured with a non elastic cotton thread and the distance between the horns were measured with the vernier caliper of 0.02 mm accuracy. RESULTS The mean peripheral lengths of the medial and lateral menisci were 99.06 +/- 11.21 and 90.25 +/- 9.36 mm respectively. The inner border lengths for the same were determined as 55.44 +/- 8.37 and 50.63 +/- 5.33 mm respectively. The distances between the anterior and posterior horns were 24.13 +/- 4.19 and 11.31 +/- 3.86 mm for the same. The peripheral length and inter horn distance of the medial meniscus was more than the lateral, the statistically significance was observed (*p<0.05). The other parameters obtained were statistically not significant. CONCLUSION The present study had determined some important anatomical data which may be of importance to the orthopaedic literature. The findings are also enlightening for the anthropologists and clinical anatomists.

Abstract
Clinico-radiological features of two patients with cerebrospinal fluid polymerase chain reaction-positive Epstein Barr virus (EBV) encephalitis have been reported. Both the patients presented with fever and altered sensorium, one had visual hallucination, decerebration followed by visual loss and the other had downward ocular deviation and orofacial and upper limb choreiform movement. Magnetic resonance imaging (MRI) revealed parieto-occipital involvement in both the patients. Follow-up MRI at one month was normal in one and revealed regression of lesion in the other. Both the patients, however, had severe neurologic sequelae at 18 months' follow-up. EBV encephalitis may have diverse clinical presentation with characteristic parieto-occipital involvement.

Abstract
OBJECTIVES Microbeam radiotherapy (MRT) with wafers of microscopically narrow, synchrotron generated X-rays is being used for pre-clinical cancer trials in animal models. It has been shown that high dose MRT can be effective at destroying tumours in animal models, while causing unexpectedly little damage to normal tissue. The aim of this study was to use a dermatopathological scoring system to quantify and compare the acute biological response of normal mouse skin with microplanar and broad-beam (BB) radiation as a basis for biological dosimetry. METHOD The skin flaps of three groups of mice were irradiated with high entrance doses (200 Gy, 400 Gy and 800 Gy) of MRT and BB and low dose BB (11 Gy, 22 Gy and 44 Gy). The mice were culled at different time-points post-irradiation. Skin sections were evaluated histologically using the following parameters: epidermal cell death, nuclear enlargement, spongiosis, hair follicle damage and dermal inflammation. The fields of irradiation were identified by γH2AX-positive immunostaining. RESULTS The acute radiation damage in skin from high dose MRT was significantly lower than from high dose BB and, importantly, similar to low dose BB. CONCLUSION The integrated MRT dose was more relevant than the peak or valley dose when comparing with BB fields. In MRT-treated skin, the apoptotic cells of epidermis and hair follicles were not confined to the microbeam paths.

Abstract
The remarkable enhancement of the crystalline perfection of benzophenone (BP) crystals induced by liquid crystal (LC) doping has been investigated, and has in turn led to better optical properties. High-resolution X-ray diffractometry demonstrates that the structural grain boundaries present in pure crystals can be eliminated when the crystal is grown with LC doping. Thus, the high alignment capability of LCs has for the first time been utilized to enhance the quality of BP bulk single crystals. The LC-doped crystal exhibits higher optical transparency over its entire transparent region. The optical polarizing behaviour of the doped BP crystal is also improved.

Abstract
In the present work, three-dimensional quantitative structure-activity relationship (3-D QSAR) studies on a set of 70 anthranilimide compounds has been performed using docking-based as well as substructure-based molecular alignments. This resulted in the selection of more statistically relevant substructure-based alignment for further studies. Further, molecular models with good predictive power were derived using CoMFA (r² = 0.997; Q² = 0.578) and CoMSIA (r² = 0.976; Q² = 0.506), for predicting the biological activity of new compounds. The so-developed contour plots identified several key features of the compounds explaining wide activity ranges. Based on the information derived from the CoMFA contour maps, novel leads were proposed which showed better predicted activity with respect to the already reported systems. Thus, the present study not only offers a highly significant predictive QSAR model for anthranilimide derivatives as glycogen phosphorylase (GP) inhibitors which can eventually assist and complement the rational drug-design attempts, but also proposes a highly predictive pharmacophore model as a guide for further development of selective and more potent GP inhibitors as anti-diabetic agents.

Abstract
It is currently estimated that infections and inflammatory responses are linked to 15-20% of all deaths from cancer worldwide. Many studies point to an important role of inflammation in prostate growth, although the contribution of inflammation to benign prostatic hyperplasia and prostate cancer is not completely understood. There is an unmet need for epidemiologic and molecular pathologic approaches to address the issue of inflammation and prostate cancer. Here we review the published evidence with respect to the involvement of inflammation and infection in prostate cancer. We also present an overarching hypothesis that chronic inflammation associated with aging and infection may play an important role in the etiology and progression of prostate cancer. As such, chronic inflammation may represent an important therapeutic target in prostate cancer.

Abstract
BACKGROUND Primary spontaneous intracerebral hemorrhage (PSICH) is common in Asia and may have a genetic basis. OBJECTIVE To report the role of angiotensin-converting enzyme (ACE) and a ADDUCIN (ADD1) gene polymorphisms in patients with PSICH. SETTING Tertiary care teaching referral hospital. PATIENTS AND METHODS Study subjects included 104 patients with PSICH diagnosed by computed tomography (CT) brain scan and 198 controls. The vascular risk factors of stroke were noted. The location and size of the hematoma on CT scan were recorded. ACE (rs4646994) and a ADDUCIN (rs4961) gene polymorphisms were analyzed by polymerase chain reaction (PCR). The genotype and allele frequency were compared between patients and controls and within the PSICH group. RESULTS The median age of the PSICH group was 58 years, 17 (16.3%) patients were aged above 70 years and 40 (38%) were females. Ninety-three (91.2%) patients were hypertensive and 17 (16.5%) were diabetic. Hematoma was putaminal in 88 (84.5%), pontine in 5 (4.9%), cerebellar in 2 (1.9%), lobar in seven (6.8%) and multiple and primary intraventricular in one (1%) patient each. In the patients with PSICH, ACE DD genotype was present in 44 (42.8%) and ID in 40 (38.4%) whereas in controls these were 22 (11.1%) and 103 (52%) respectively. ADD1- WW genotype was found in two patients (1.9%), and GW in 44 patients (42.7%). In the controls these were found in nine (4.5%) and 65 (32.8%) respectively. DD genotype had 7.4 times higher risk of PSICH. ADD1 variant genotypes were not associated with increased risk but in association with ACE DD genotype resulted in significantly higher risk of PSICH. ACE and ADD1 variant genotypes were associated with nonlobar hematoma. CONCLUSION ACE DD genotype in isolation or in combination with ADD1 GW genotype is associated with PSICH, especially nonlobar hematoma.

Abstract
This study has been conducted to determine the extent of genetic association between yield of Rice (Oryza sativa L.) and its components. The present experiment was carried out with 40 Rice (Oryza sativa L.) genotypes which were evaluated in a randomized block design with 3 replications during wet season of 2007 and 2008. Results showed that sufficient amount of variability was found in the entire gene pool for all traits studied. Higher magnitude of genotypic and phenotypic coefficients of variation was recorded for seed yield, harvest index, biological yield, number of spikelets per panicle, flag leaf length, plant height and number of tillers indicates that these characters are least influence by environment. High heritability coupled with high genetic advance as percent of mean was registered for seed yield, harvest index, number of spikelets per panicle, biological yield and flag leaf length, suggesting preponderance of additive gene action in the expression of these characters. Grain yield was significantly and positively associated with harvest index, number of tillers per hill, number of panicle per plant, panicle length, number of spikelet's per panicle and test weight at both genotypic and phenotypic levels. Path coefficient analysis revealed that harvest index, biological yield, number of tillers per hill, panicle length, number of spikelets per panicle, plant height and test weight had direct positive effect on seed yield, indicating these are the main contributors to yield. From this study it may be concluded that harvest index, number of tillers per hill, panicle length and number of spikelet per panicle and test weight are the most important characters that contributed directly to yield. Thus, these characters may serve selection criteria for improving genetic potential of rice.

Abstract
BACKGROUND Central airway obstruction (CAO) is defined as obstruction of trachea and principal bronchi. Therapeutic rigid bronchoscopy with tracheobronchial stenting using silicon stents is a well established procedure in the management of such conditions. However, there is limited experience with this technique in India. METHODS Between January 2010 and April 2010, Dumon stents were placed in four patients with CAO. Three patients had symptomatic tracheal stenosis while one patient had malignant obstruction at the carina. Rigid bronchoscopy under general anaesthesia was performed to relieve the CAO followed by placement of silicon stents. Pre- and post-stent placement symptom assessment was performed with a symptom-based visual analogue scale. RESULTS Four patients underwent silicon stent placement in the tracheobronchial tree. Three patients had benign post-intubation tracheal stenosis and one had malignant tracheal obstruction at carina due to endobronchial growth. Significant improvement was achieved in all patients. There were no significant complications. CONCLUSIONS Rigid bronchoscopy with silicon stent placement is an effective and suitable method of relieving the distressing symptoms due to benign or malignant airway obstruction.

Abstract
Rotavirus has been recognized as a predominant cause of acute diarrhea in young animals and humans. Rotavirus has segmented genome composed of 11 segments of double stranded RNA. The virus has a triple layered protein shell consisting of a core, an inner capsid and an outer capsid. The inner capsid protein is responsible for group specificity and based on it rotaviruses are classified into seven groups. Ovine rotavirus strains have only been identified into two serogroups (A and B). The two outer capsid proteins (VP7 and VP4) are responsible for G and P typing of rotavirus, respectively. Although rotavirus has been frequently reported in many animal species, data regarding ovine rotavirus strains is very scanty and limited. Only a few ovine rotaviruses have been isolated and characterized so far. Recently, the G and P types circulating in ovines have been identified. The ovine rotavirus strain NT isolated from a diarrheic lamb in China is being considered as a promising vaccine candidate for human infants.

Abstract
Securing the airway in patients with severe post burn contracture of the neck is often challenging for attending anesthesiologists. Fiberoptic bronchoscope (FOB)-guided endotracheal intubation is considered safe and reliable in this situation. Intubating Laryngeal Mask Airway (ILMA) is an alternative in case of FOB unavailability. We report a case of 30 year old female with mentosternal contracture, where the use of ILMA allowed easy ventilation but failed to enable successful ILMA-guided blind intubation despite multiple attempts, the use of recommended Chandey's maneuver and muscle relaxation. Subsequent FOB revealed marked anterior dislocation of laryngotracheal structures, leading to a slippage of the endotracheal tube back to the esophagus.

Abstract
A real-time RT-PCR assay was standardized and evaluated for the detection of the recent pandemic 2009 H1N1 strain that circulated around the world causing colossal loss of human life. We amplified the conserved regions of the hemagglutinin (HA) gene of 438 clinical specimens using real-time RT-PCR assay for rapid identification of pandemic influenza virus. The real-time RT-PCR was optimized and the primers and probes were tested against a panel of known negative and positive controls. RNA isolated from the HeLa cell line served as quality control. The conventional RT-PCR which is an established method of influenza virus diagnosis was compared to real-time RT-PCR. Of 438 clinical specimens tested, 212 specimens were found positive for influenza A virus (SD 46.669) in which 139 specimens were diagnosed positive for the pandemic 2009 H1N1 while 73 were the seasonal influenza viruses. We report that the real-time RT-PCR assay offers both, a high sensitivity and specificity when compared with the traditional identification method. The real-time RT-PCR assay allows rapid identification of the pandemic swine 2009-H1N1 at very low viral loads that are negative by the traditional RT-PCR. This optimized assay can be a very useful tool to assist both epidemiologists and the clinicians.

Abstract
The influenza virus generally causes damage to epithelial cells of respiratory tract and infection of cells with this virus often results in cell death with apoptotic characteristics. Reports are available implicating influenza virus as a causative agent of chromosomal aberrations in cells and culture. The objective of this study was to analyze the process of cell death caused by influenza virus (A/Udorn/317/72, H3N2) infection in cultured HeLa cells by electron microscopy and comet assay. The apoptotic study was performed using light microscopy electron microscopy and comet assay to observe the changes in cell morphology and DNA fragmentation. HeLa cells, infected with influenza virus were harvested at various time periods to observe the ultrastructural changes. This infection gave rise to nuclear fragmentation and chromatin condensation accompanied by chromosomal DNA fragmentation into oligonucleosomes. The pattern of comet assay revealed that the apoptosis occurred due to fragmentation of the DNA of the cells which reached the maximum level at 36 h post infection. Ultrastructural study showed extensive chromatin condensation and nuclear fragmentation which are the characteristic features of apoptosis.

Abstract
Endometriosis of abdominal wall scar following operation on uterus and tubes is extremely rare. The late onset of symptoms after surgery is the usual cause of misdiagnosis. Scar endometriosis is a rare disease which is difficult to diagnose and should always be considered as a differential diagnosis of painful abdominal masses in women. The diagnosis is made only after excision and histopathology of the lesion. Preoperative differentials include hernia, lipoma, suture granuloma or abscess. Hence an awareness of the entity avoids delay in diagnosis, helps clinicians to a more tailored treatment and also avoids unnecessary referrals. We report a case of abdominal endometriosis. The definitive diagnosis of which was established by histopathological studies.
