Abstract
Anatase-titania nanotubes have been synthesized via hydrothermal and surface-modified by depositing silver and palladium via ultraviolet-reduction method. The pure and surface-modified anatase-titania nanotubes have been characterized using the transmission electron microscope, selected-area electron diffraction, X-ray diffraction, diffuse reflectance, photoluminescence, and Fourier transform infrared spectroscope to reveal their average size, structure, and surface-chemistry. The nanotubes have been utilized for the dye-removal application involving the surface-adsorption mechanism under the dark-condition and photocatalytic degradation mechanism under the ultraviolet-radiation exposure. The variation in the dye-concentration during the dye-adsorption and photocatalysis processes has been determined using the ultraviolet-visible absorption spectrophotometer with methylene blue as a model catalytic dye-agent. It has been shown that silver-deposited anatase-titania nanotubes are more effective in enhancing the kinetics of the dye-removal via surface-adsorption and photocatalytic degradation mechanisms relative to the palladium-deposited anatase-titania nanotubes, which has been attributed to the differences in the surface-chemistry of anatase-titania nanotubes induced by the respective metal-deposition.

Abstract
The nanotubes of pure hydrogen titanate and anatase-titania have been synthesized via hydrothermal treatment of as-received anatase-titania particles. The formation mechanism of anatase-titania nanotubes via hydrothermal has been discussed in detail in view of the finger-prints produced by characterizing the intermediate and end products using various microscopic and spectroscopic techniques such as scanning electron microscope, high-resolution transmission electron microscope, X-ray diffraction, Brunauer, Emmett, and Teller specific surface-area measurement, Fourier transform infrared spectroscope, diffuse reflectance, photoluminescence, thermal gravimetric and differential thermal analyses. The obtained results strongly support the rollup mechanism, involving multiple nanosheets, for the formation of anatase-titania nanotubes with the formation of different intermediate hydrothermal products having various morphologies such as sodium titanate having aggregated rectangular block-like structures, hydrogen sodium titanate and pure hydrogen titanate having highly aggregated unresolved fine-structures containing nanotubes, and finally, the pure anatase-TiO2 nanotubes. It is demonstrated that, during the hydrothermal treatment, the nanotubes of pure hydrogen titanate are formed first coinciding with the stable solution-pH during washing, indicating the completion of ion-exchange process, and a drastic increase in the specific surface-area of the hydrothermal product. The anatase-titania nanotubes are then derived from the pure hydrogen titanate nanotubes via thermal treatment. The use of pure hydrogen titanate and anatase-titania nanotubes for an organic textile dye-removal, from an aqueous solution under the dark condition, via surface-adsorption mechanism has been demonstrated. It is shown that, the specific surface-area and the surface-charge govern the maximum dye-absorption capacity of the anatase-TiO2 nanotubes under the dark condition.

Abstract
In contrast to the two distinct energy regions that are involved in dual-energy x-ray absorptiometry for bone densitometry, the complete spectrum of a beam transmitted through two layers of different materials is utilized in this study to calculate the areal density of each material. Test objects constructed from aluminum and Plexiglas were used to simulate cortical bone and soft tissue, respectively. Solid-state HPGe (high-purity germanium) detectors provided high-resolution x-ray spectra over an energy range of approximately 20-80 keV. Areal densities were obtained from spectra using two methods: a system of equations for two spectral regions and a nonlinear fit of the entire spectrum. Good agreement with the known areal densities of aluminum was obtained over a wide range of PMMA thicknesses. The spectral method presented here can be used to decrease beam hardening at a small number of bodily points selected for examination.

Abstract
BACKGROUND As the tumor spreads through the pathway of least resistance, the present study was carried out to evaluate the presence of perineural infiltration and spread of oral squamous cell carcinoma (OSCC) along the perineural spaces in gingivobuccal sulcus tumors infiltrating into the mandible. AIMS AND OBJECTIVES (1) To investigate the incidence of perineural invasion of OSCC along the inferior alveolar nerve and (2) to investigate the neurovascular bundle as a potential route of spread of OSCC. MATERIALS AND METHODS Twenty-six patients with histopathologically proven OSCC of the gingivobuccal sulcus with radiographic infiltration of the mandible were included. The surgical specimens were decalcified and serially sectioned. Each section was stained with hematoxylin and eosin and was screened for the presence of perineural invasion and spread. Results : Twenty-five specimens showed perineural infiltration but none of the cases showed perineural spread along the inferior alveolar canal. Also, not all cases showed any neurologic deficit. Follow-up of these cases showed early recurrence (6-8 months) in the study group. CONCLUSION Perineural infiltration is present in OSCC but perineural spread along the inferior alveolar canal is absent. It is a bad prognostic indicator.

Abstract
We report the results of a study carried out to investigate the effect of helium-neon (He-Ne) laser (632.8 nm) irradiation on the hair follicle growth cycle of testosterone-treated and untreated mice. Both histology and optical coherence tomography (OCT) were used for the measurement of hair follicle length and the relative percentage of hair follicles in different growth phases. A positive correlation (R = 0.96) was observed for the lengths of hair follicles measured by both methods. Further, the ratios of the lengths of hair follicles in the anagen and catagen phases obtained by both methods were nearly the same. However, the length of the hair follicles measured by both methods differed by a factor of 1.6, with histology showing smaller lengths. He-Ne laser irradiation (at approximately 1 J/cm(2)) of the skin of both the control and the testosterone-treated mice was observed to lead to a significant increase (p < 0.05) in % anagen, indicating stimulation of hair growth. The study also demonstrates that OCT can be used to monitor the hair follicle growth cycle, and thus hair follicle disorders or treatment efficacy during alopecia.

Abstract
To compare the effect of honey dressing and silver-sulfadiazene (SSD) dressing on wound healing in burn patients. Patients (n=78) of both sexes, with age group between 10 and 50 years and with first and second degree of burn of less than 50% of TBSA (Total body surface area) were included in the study, over a period of 2 years (2006-08). After stabilization, patients were randomly attributed into two groups: 'honey group' and 'SSD group'. Time elapsed since burn was recorded. After washing with normal saline, undiluted pure honey was applied over the wounds of patients in the honey group (n=37) and SSD cream over the wounds of patients in SSD group (n=41), everyday. Wound was dressed with sterile gauze, cotton pads and bandaged. Status of the wound was assessed every third and seventh day and on the day of completion of study. Patients were followed up every fortnight till epithelialization. The bacteriological examination of the wound was done every seventh day. The mean age for case (honey group) and control (SSD group) was 34.5 years and 28.5 years, respectively. Wound swab culture was positive in 29 out of 36 patients who came within 8 hours of burn and in all patients who came after 24 hours. The average duration of healing in patients treated with honey and SSD dressing at any time of admission was 18.16 and 32.68 days, respectively. Wound of all those patients (100%) who reported within 1 hour became sterile with honey dressing in less than 7 days while none with SSD. All of the wounds became sterile in less than 21 days with honey, while tthis was so in only 36.5% with SSD treated wounds. The honey group included 33 patients reported within 24 hour of injury, and 26 out of them had complete outcome at 2 months of follow-up, while numbers for the SSD group were 32 and 12. Complete outcome for any admission point of time after 2 months was noted in 81% and 37% of patients in the honey group and the SSD group. Honey dressing improves wound healing, makes the wound sterile in lesser time, has a better outcome in terms of prevention of hypertrophic scarring and post-burn contractures, and decreases the need of debridement irrespective of time of admission, when compared to SSD dressing.

Abstract
e22213 Background: Recently, breast cancer has become the most common cancer among women in all urban population in India. Annually about 80000 new cases and 40000 deaths occur and majority of breast cancers are pre-menopausal. Conventional diagnostic methods are not very sensitive especially in early stages of cancer. This necessitated a more sensitive and reliable method for early diagnosis leading to effective treatment, better prognosis and survival. Recently, the level of cell free circulating tumor DNA in blood plasma or serum of patients with variety of tumors are being considered as reliable non-invasive diagnostic tool but no study has been done in India. The present study has therefore been undertaken to evaluate clinical utility of cell free DNA as potential biomarkers for early diagnosis and management of breast cancer. Methods: 25 newly diagnosed untreated breast cancer patients and 25 healthy subjects having no sign of significant medical illness with informed consent were enrolled for the study. 9 patients after chemotherapy were also included in the study. Blood plasma collected from both patients and controls were employed for DNA isolation, using Qiagen kit. Concentration of cell free plasma DNA was analyzed by 3 methods viz. nanodrop spectro-photometry, integrated density value (IDV) of PCR products of Exon 7 of p53 gene and quantitative real time PCR (cycles threshold converted to genome equivalent). All values of DNA concentration obtained by three methods used as continuous variables and receiver operating characteristic (ROC) were plotted and the cut-of value was determined at 90% sensitivity and 100% specificity level of ROC. Results: Mean free plasma DNA concentration as determined by both Q-RT PCR and IDV in cancer patients was found to be significantly higher in advanced stage breast cancer patients than in controls (genome equivalent 18850 vs 431; IDV 17912 vs 4197; p=0.001). However, no significant difference could be observed in early stage disease as compared to controls possibly due small sample size. Conclusions: Free Plasma DNA concentration is a reliable molecular marker for detection of breast cancer and can serve as a prognostic indicator leading to its potential clinical application either alone or in combination with other conventional methods. No significant financial relationships to disclose.

Abstract
We examined the incidence of infection with methicillin-resistant Staphylococcus aureus (MRSA) in patients admitted to the Leicester Royal Infirmary Trauma Unit between January 2004 and June 2006. The influence of MRSA status at the time of their admission was examined, together with age, gender and diagnosis, using multi-variant analysis. Of 2473 patients, 79 (3.2%) were MRSA carriers at the time of admission and 2394 (96.8%) were MRSA-negative. Those carrying MRSA at the time of admission were more likely to develop surgical site infection with MRSA (7 of 79 patients, 8.8%) than non-MRSA carriers (54 of 2394 patients, 2.2%, p < 0.001). Further analysis showed that hip fracture and increasing age were also risk factors with a linear increase in relative risk of 1.8% per year. MRSA carriage at admission, age and the pathology are all associated with an increased rate of developing MRSA wound infection. Identification of such risk factors at admission helps to target health-care resources, such the use of glycopeptide antibiotics at induction and the ‘building-in’ of increased vigilance for wound infection pre-operatively.

Abstract
Scientists interested in contamination normally deal only with pollution itself, not with people's perceptions of pollution or the relationship between pollution and land use. The overall objective of this article was to examine the relationship between people's perceptions of pollution and their views on future land use. People were interviewed at an Earth Day Festival near the Department of Energy's Brookhaven National Laboratory (BNL) on Long Island, New York. On an open-ended question, people thought that BNL should be left as it is, or maintained as a preserve, park or conservation area, or used for environmental research. Almost no one thought that it should be used for housing or industrial purposes. When asked to rate a list of possible future land uses, maintaining BNL as a National Environmental Research Park for research and for recreation were rated the highest (nuclear storage was rated the lowest). This was consistent with the subjects' views that pollution was the greatest concern about BNL. The congruence between perceptions about concerns or problems and future land use preferences suggests a unified view of management of contaminated sites, such as BNL, at least among a group of people whose environmental interests were evident by their presence at the event.
