Abstract
The quantitative assessment of micro-structure and load-induced damages in Al-SiC metal matrix composites (MMC) is important for its design optimization, performance evaluation and structure-property correlation. X-ray Phase contrast micro-tomography is potentially used for evaluation of its 3 dimensional micro-structure manifested in the form of voids, cracks, embedded particles, and load-induced damages. However, the contrast between Al matrix and SiC particles is insufficient for their clear morphological identification and quantitative assessment. In the present study, we have proposed and applied single image-based phase retrieval as a pre-processing step to micro-tomography reconstruction for improved assessment of micro-structure and cohesion-induced damages in Al-SiC MMC. The advantages of applying different phase retrieval techniques in the enhancement of image quality and morphological quantification of SiC particles, pores and cohesion damages are discussed. It is observed that the Paganin method offers the best improvement in contrast to noise ratio for the measurement of SiC particles embedded in the Al matrix.

Abstract
There is growing evidence of beneficial effects of mindfulness developed through engaging in mindfulness training/practices on sensory and cognitive processing, emotion regulation and mental health. Mindfulness has also been conceptualised as a dispositional 'trait', i.e. the naturally-occurring ability of meditation-naïve individuals to display, in varying degree, a non-judgmental non-reactive present-moment awareness in everyday life. In this study we examined possible associations between dispositional mindfulness, alexithymia and sensory processing. Eye-blink startle responses to acoustic stimuli of varying intensity [90-dB or 100-dB over 70-dB (A) background] were assessed in 26 meditation-naïve adults (50 % men) using electromyographic recordings of the orbicularis muscle. All participants completed the Five Facet Mindfulness Questionnaire and the 20-item Toronto Alexithymia Scale. A negative association was found between dispositional mindfulness and alexithymia (r = -0.513). There was stronger startle habituation to 100-dB, compared to 90-dB probes. Stronger startle habituation (larger negative habitation slope values) to 100-dB probes was significantly associated with higher dispositional mindfulness (r = -0.528) and with lower alexithymia at trend level (r = 0.333). As indicated by commonality analysis, 10.6 % of explained variance in habituation (100-dB probes) was common to both alexithymia and mindfulness, 17.3 % was unique to mindfulness, but alexithymia made negligible unique contribution (0.5 %). These findings indicate similar startle habituation pattern in people with a high level of dispositional mindfulness to that reported previously by Antonova et al. (2015) in people with moderate mindfulness meditation practice intensity. Future studies should investigate the mechanisms, such as interoceptive awareness, that might underly these relationships.

Abstract
BACKGROUND Tezepelumab is a human monoclonal antibody that blocks thymic stromal lymphopoietin. The drug has been tested previously in the phase 3 NAVIGATOR (NCT03347279) and SOURCE (NCT03406078) studies, and was subsequently approved as a treatment for severe asthma. This extension study recruited from NAVIGATOR and SOURCE and aimed to evaluate the long-term safety and efficacy of tezepelumab in individuals with severe, uncontrolled asthma. METHODS DESTINATION was a phase 3, multicentre, randomised, double-blind, placebo-controlled, long-term extension study. The study was done across 182 sites (including hospitals, clinics, medical centres, clinical trial centres, and private practices) in 18 countries. Participants (aged 12-80 years) were required to have good treatment compliance in the parent study. Randomisation was stratified by the parent study and all participants were re-randomised. Those who were previously randomised to receive tezepelumab in either parent study continued treatment of subcutaneous tezepelumab (210 mg every 4 weeks); those who were previously randomised to receive placebo in either parent study were re-randomised 1:1 to receive either subcutaneous tezepelumab (210 mg every 4 weeks) or placebo (every 4 weeks) using a randomisation list prepared by a computerised system. Total treatment duration (including the parent studies) was 104 weeks for all groups. Participants, investigators, and site staff were masked to treatment assignment. The primary endpoints were exposure-adjusted incidence of adverse events and serious adverse events and the secondary endpoint was the annualised asthma exacerbation rate; these were assessed from week 0 of the parent studies to week 104 of DESTINATION in all participants who were randomised and who received at least one dose of tezepelumab or placebo in either of the parent studies. The trial is registered with ClinicalTrials.gov, NCT03706079, and is closed to new participants. FINDINGS Participants were recruited between Jan 7, 2019, and Oct 15, 2020. For individuals who initially received tezepelumab (n=528) in NAVIGATOR, incidence of adverse events over 104 weeks was 49·62 (95% CI 45·16 to 54·39) per 100 patient-years, compared with 62·66 (56·93 to 68·81) for those receiving placebo (n=531; difference -13·04, 95% CI -17·83 to -8·18). For serious adverse events, incidence was 7·85 (6·14 to 9·89) per 100 patient-years for individuals who initially received tezepelumab and 12·45 (9·97 to 15·35) for those who received placebo (difference -4·59, -7·69 to -1·65). In SOURCE, incidence of adverse events was 47·15 (36·06 to 60·56) per 100 patient-years for those who initially received tezepelumab (n=74) and 69·97 (54·54 to 88·40) for those who received placebo (n=76; difference -22·82, -34·77 to -10·01). For serious adverse events, incidence was 13·14 (7·65 to 21·04) per 100 patient-years for those who initially received tezepelumab and 17·99 (10·66 to 28·44) for those who received placebo (difference -4·85, -14·88 to 4·53). Tezepelumab reduced the annualised asthma exacerbation rate over 104 weeks compared with placebo. In participants initially from NAVIGATOR, the annualised asthma exacerbation rate ratio over 104 weeks was 0·42 (95% CI 0·35 to 0·51); in those initially from SOURCE, the ratio over 104 weeks was 0·61 (0·38 to 0·96). INTERPRETATION Tezepelumab treatment was well tolerated for up to 2 years and resulted in sustained, clinically meaningful reductions in asthma exacerbations in individuals with severe, uncontrolled asthma. These findings are consistent with previous randomised, placebo-controlled studies and show the long-term safety and sustained efficacy of tezepelumab in individuals with severe, uncontrolled asthma.

Abstract
Joint inflammation results from soft-tissue injuries and cartilage damage. PRICE is the standard treatment approach for acute soft tissue injuries like ankle sprain. Electrical stimulation, application of orthotic braces, etc. is also effective for this. In a synergistic device all these components are combined and applied simultaneously. This device was developed for joint inflammation and tested for grade I & II acute ankle joint sprain. To test a synergistic - semirigid device, combining PRICE & electrical stimulation for acute ankle sprains of grades I & II for pain, range of motion and swelling is a case series was the objective. Device was developed using novel concept of synergistic applications of PRICE with electrical stimulation. The joint contour of ankle and specific biomechanical bony surface landmarks were considered. Ethical approval was taken from NTCC committee, AIPT. Recordings were taken from eight patients of acute ankle sprain with - in two days of injury, after getting ethical approval. Elevation to the ankle was provided by keeping the part over the pillow and data was recorded with the help of: 1.VAS scale for pain; 2. Measuring tape; 3. Goniometry. t-test was used to find out the significant difference pre and post the application of device. There was a significant reduction in pain (p = 0.006), edema (p = 0.011), dorsi-flexion (p = 0.015), and plantar flexion (p =0.008). The synegistic device has been effective for acute ankle inflammation - grade I & II ankle sprains in 5 sessions; sufficient for the return of function.

Abstract
Objectives: 1. To assess the strength of hamstring and quadriceps in patients with knee OA with 1 RM.
To compare the strength of hamstring and quadriceps with normal individuals.
Research Design: Observational study.
Introduction: Quadriceps and hamstring muscle weakness is commonly found in knee OA which may alter normal Quadriceps/Hamstrings ratio i.e. (2:1). So the purpose of the study was to check the strength of the quadriceps and hamstring muscle in OA knee patients and compare it with normal individual.
Method: 20 diagnosed knee OA patients and 21 normal individuals were recruited. Quadriceps and hamstring muscle strength was measured in both case and normal group by using 1 RM method. Q/H ratio was obtained from the muscle strength and both were compared between two groups by using T test.
Materials: Quadriceps table, Metal weight plate, Plinth, Sand bag.
Results & Discussion: Quadriceps and hamstring strength were reduced significantly (p=<0.001) in patients with knee OA compare to normal individual. There was negative co relation between pain and muscle strength seen. No alteration in Q/H ratio (Rt knee p=0.130; Lt knee p=0.722) between the case & control found because both the muscle strength reduced similarly.
Conclusion: Quadriceps and hamstring muscle strength is significantly reduced in OA knee.
Patients compare to normal individuals but no alteration in Q/H ratio seen in both groups.

Abstract
The high flux density of synchrotron white beam offers several advantages in X-ray imaging such as higher resolution and signal-to-noise ratio in 3D/4D micro-tomography, higher frame rate in real-time imaging of transient phenomena, and higher penetration in thick and dense materials especially at higher energies. However, these advantages come with additional challenges to beamline optics, camera and sample due to increased heat load and radiation damage, and to personal safety due to higher radiation dose and ozone gas hazards. In this work, a white beam imaging facility at imaging beamline BL-4, Indus-2, has been developed, while taking care of various instrumental and personal safety challenges. The facility has been tested to achieve 1.5 µm spatial resolution, increased penetration depth up to 900 µm in steel, and high temporal resolutions of ∼10 ms (region of interest 2048 × 2048 pixels) and 70 µs (256 × 2048 pixels). The facility is being used successfully for X-ray imaging, non-destructive testing and dosimetry experiments.

AIM to compare anulom vilom pranayama (AVP), kapal bhati pranayama (KBP), diaphragmatic breathing exercises (DBE), and pursed-lip breathing (PLB) for breath holding time (BHT) and rating of perceived exertion (RPE). Methods- Participants were assessed for BHT and RPE, before training on any one intervention using online platforms, for one week during lockdown from COVID-19.15 participants in each group total N = 60 at- (α - 0.05), (1- β - 0.90) & (effect size - 0.55); were analysed. Results - AVP & DBE decreased RPE (p < 0.000). KBP & PLB did not decrease RPE as compared to AVP & DBE (p. > 0.05). DBE increased BHT more than KBP & PLB interventions (p < 0.05), but not more than AVP (p > 0.05). One-way ANOVA of four interventions revealed significant variation for RPE change (p < 0.05), for AVP. Conclusions - AVP reduces RPE maximally during breath-holding, whereas DPE increases BHT more.

Abstract
Flame-retardant polyurethane foams are potential packing materials for the transport casks of highly active nuclear materials for shock absorption and insulation purposes. Exposure of high doses of gamma radiation causes cross-linking and chain sectioning of macromolecules in this polymer foam, which leads to reorganization of their cellular microstructure and thereby variations in physico-mechanical properties. In this study, in-house-developed flame-retardant rigid polyurethane foam samples were exposed to gamma irradiation doses in the 0-20 kGy range and synchrotron radiation X-ray micro-computed tomography (SR-µCT) imaging was employed for the analysis of radiation-induced morphological variations in their cellular microstructure. Qualitative and quantitative analysis of SR-µCT images has revealed significant variations in the average cell size, shape, wall thickness, orientations and spatial anisotropy of the cellular microstructure in polyurethane foam.

Abstract
Background and Aim In the recent past,few studies have been carried out in chicken to assess the effect of Azolla meal and raw Azolla feeding on the performance of chicken. If turkeys effectively use unconventional feedstuffs like Azolla without reducing the performance, it will increase the profitability of turkey business. Hence, a study was carried out to evaluate the effect of dried Azolla pinnata vis-a-vis raw Azolla as choice feeding on the growth, feed conversion ratio (FCR), blood biochemical attributes, and immune competence traits of growing turkeys under intensive system. Materials and Methods A total of 72, 8-week-old grower turkey poults of black variety were randomly distributed into three dietary treatments having three replicates each with eight birds. The birds of the control group (T1) were fed a basal diet (CP - 19.71% and ME - 2789.79 Kcal/kg), while the other group (T2) and choice-feeding group (T3) were fed 5% of basal diet replaced by dry Azolla powder on DM basis and ad libitumAzolla along with basal diet, respectively. Results There was no significant difference among the different groups in the average weekly weight gain during the entire experiment. FCR was significantly better (p<0.05) in the choice-feeding group compared to the other two experimental groups during 8-16 weeks of age. There was no significant difference among the treatment groups in any of the blood biochemical indices except plasma uric acid, which was significantly decreased (p<0.01) in T2 compared to T1 at 16 weeks of age. HA and IgM response to 1% sheep red blood cells (log2 titer) were numerically better in T2 and T3 compared to the T1. Conclusion Thus, it may be inferred that choice feeding with Azolla, and basal diet may improve FCR without any adverse effect on blood biochemical attributes and immune competence traits.

Abstract
Contemporary healthcare has progressed towards world health security through advancements in medication-based and surgical interventions, supported by the success of antimicrobial therapy. The emergence of panresistant infectious diseases is becoming a public health problem worldwide. Panresistance is attributable to a complex interplay of antimicrobial overuse in healthcare facilities due to lack of regulatory commitment in the backdrop of natural mutations in pathogens and rise in immunocompromised hosts. Developing countries are facing the brunt in epidemic proportions due to strained public health infrastructure and limited resource allocation to healthcare. Panresistance is a biological, behavioural, technical, economic, regulatory and educational problem of global concern and combating it will require concerted efforts to preserve the efficacy of the available antimicrobials. An intensified commitment needs to be taken up on a war footing to increase awareness in the society, increase laboratory capacity, facilitate antimicrobial research, foster emphasis on infection control and antimicrobial stewardship, and legislation on manufacturing, marketing and dispensing of antimicrobials.

Abstract
Abstract
Circulating tumor DNA (ctDNA) is released from tumor tissue into the blood, carries tumor specific genetic alterations, and can be analyzed through noninvasive "liquid biopsy" approaches to identify genetic alterations in cancer patients. Liquid biopsies offer a considerable advantage as they may eliminate the need for invasive tissue biopsies and allow for the detection of alterations in multiple metastatic lesions throughout the course of therapy. However, the fraction of ctDNA obtained from a blood sample is often very low (<1.0%) and can be difficult to detect. Additionally, most methods to evaluate circulating tumor DNA (ctDNA) interrogate single hot spot mutations or few genetic alterations. The next generation of ctDNA assays must interrogate multiple gene regions from a single sample with high precision and accuracy and need to evaluate all forms of actionable genomic alterations including point mutations, amplifications, and translocations. To address these issues, we have developed a ctDNA approach called PlasmaSelect to detect somatic sequence mutations, amplifications and translocations at low allele frequencies in the circulation of cancer patients. Utilizing digital genomic approaches, PlasmaSelect achieves high sensitivity and specificity while interrogating >250,000 nucleotides spanning 63 well-established cancer genes. In addition to sequence mutations in the entire coding region of 18 genes and the exons of 40 genes that are frequently mutated in cancer, PlasmaSelect also performs a comprehensive genomic analysis of amplifications in 57 genes and translocations in 10 genes significant in cancer tumorigenesis. To evaluate the PlasmaSelect approach, we performed dilution series using tumor-derived DNA, containing well-characterized somatic mutations, in the presence of wild-type DNA. PlasmaSelect was able to detect genetic alterations with high specificity and a lower level of detection of 0.10% for sequence mutations and translocations, as well as a focal amplification of ERBB2 with a lower level of detection of 0.20%. We evaluated the clinical utility of PlasmaSelect for detection of genetic alterations in the plasma and matched tissue biopsy specimens from late stage cancer patients. These analyses demonstrated high concordance between the somatic sequence mutations, amplifications, and translocations identified in the tumor sample and those identified directly in the plasma, including alterations in both driver genes as well as those related to acquired resistance to targeted therapies. PlasmaSelect provides a non-invasive platform to enable liquid biopsy detection of clinically relevant genetic alterations across a large number of genomic loci.

Abstract
Scientific concern exists about the toxic effect of dichlorodiphenyldichloroethylene (p, p'-DDE) and lindane on male infertility, and the mechanism underlying male reproductive toxicity of this pesticide remains unanswered. We investigated not only the possible association between the chlorinated pesticide levels and semen quality in nonoccupationally exposed men, but also the probable mode of action using mitochondrial membrane potential (MMP), reactive oxygen species (ROS), lipid peroxidation (LPO), and sperm chromatin structure assay (SCSA). A study in 278 men (21-40 years old) who visited Obstetrics and Gynecology Department, KGMU, Lucknow, for semen analysis was conducted. We performed semen analysis according to the WHO guidelines, while p, p'-DDE and lindane analysis was done by the GLC and LPO by the spectrophotometer, and the sperm mitochondrial status, ROS, and SCSA with the flow cytometer. The questionnaire data showed no significant difference in the demographic characteristics between the two groups, i.e., trying to conceive >1 year and proven fertility. However, a significant difference in the concentration of p, p'-DDE and lindane was observed between the groups. When the subjects were divided among four categories by quartile of exposure, the subjects in the highest quartile showed low sperm motility as compared to the subjects in the lowest quartile. Pearson's correlation showed a significant negative correlation between semen p, p'-DDE, lindane level, and sperm quality and positive association with the number of cells with depolarized mitochondria, elevation in ROS production and LPO, and DNA fragmentation index (DFI). The findings are suggestive that these toxicants might cause a decline in semen quality, and these effects might be ROS, LPO, and mitochondrial dysfunction mediated.

Abstract
PURPOSE The purpose of this study is to investigate the association of the serum 25-hydroxyvitamin D (25-OHD) level with markers of insulin resistance (IR) in postmenopausal Indian women. MATERIALS AND METHODS This was a cross-sectional study, conducted at a Tertiary Care Hospital in New Delhi, India. Seventy one postmenopausal women (mean age 56.3 ± 7.6 years) were enrolled. Exclusion criteria were known or newly detected diabetics, subjects with chronic renal failure, chronic liver disease or any other chronic inflammatory condition, chronic smokers and chronic alcoholics. Serum calcium (and albumin for calculating corrected calcium), phosphorus, alkaline phosphatase and 25-OHD were measured as parameters of calcium homeostasis. Fasting blood glucose (FBG), systolic and diastolic blood pressures, body mass index (BMI), fasting serum insulin, calculated glucose insulin ratio (GIR), and homeostatic model assessment of insulin resistance (HOMA-IR) were studied as parameters of IR. Data was then analyzed for statistical significance. RESULTS The mean serum 25-OHD level was 12.73 ± 7.63 ng/ml. The mean BMI was 27.78 ± 5.37 kg/m(2). The mean calculated GIR was 13.14 ± 9.39 and HOMA-IR was 2.31 ± 1.70. Serum 25-OHD was inversely correlated with BMI (correlation coefficient -0.234, P value 0.050) and with HOMA-IR (correlation coefficient -0.237, P value 0.047). However, when 25-OHD was adjusted for BMI the correlation between 25-OHD and HOMA-IR lost its significance. No correlation was found between serum 25-OHD and any other parameters of IR studied. CONCLUSIONS There is a significant negative linear correlation between 25-OHD and BMI. The significant negative linear correlation between 25-OHD and HOMA-IR was confounded by BMI. There is no correlation between 25-OHD and parameters of IR.

Abstract
Human data on the relationship of semen quality with pesticide and metals are mostly inconsistent. The purpose of the study is to confirm the toxicity of organochlorine pesticide β- and γ-hexachlorocyclohexane (HCH), DDE and DDD, and metals lead or cadmium on sperm motility in epidemiological study among fertile and infertile men and to determine whether in vivo and in vitro results are in the same direction. Semen analysis and estimation of the toxicants were done in 60 fertile and 150 infertile men. In the in vitro studies, sperm were exposed to the highest levels of these toxicants found in vivo, as well as five and ten times higher, and to the mixture of all compounds. The study assesses sperm viability and motility for a period ranging between 30 min and 96 h. Epidemiological data showed an inverse correlation of toxicant with sperm motility. In vitro study showed that γ-HCH and lead after 12 h, cadmium after 8 h, and coexposure to toxicants after 6 h of exposure caused significant concentration- and duration-dependent decline in sperm motility. Data of in vitro study were concurrent with epidemiological finding that might be useful in establishing the possible association between exposure and effect of these selected pollutants on sperm motility.

Abstract
BACKGROUND Tibial plateau fractures are usually associated with communition and soft tissue injury. Percutaneous treatment of these complex fractures is intended to reduce soft issue complications and postoperative stiffness of the knee joint. We assessed the complications, clinical outcome scores, and postoperative knee range of movements, after fluoroscopic assisted closed reduction and external fixator application. MATERIALS AND METHODS Seventy eight complex tibial plateau fractures in 78 patients were included in the study. All fractures were managed with closed reduction and external fixator application. In 28 cases with intraarticular split, we used percutaneous cancellous screw fixation for reduction and fixation of condylar parts. In nine open fractures, immediate debridement was done. In 16 cases, elevation of depressed segment and bone grafting was required, which was done from a very small incision. All patients were clinically and radiographically evaluated at a mean followup of 26.16 months (range 6-60 months). RESULTS Clinical results were evaluated according to the Rasmussen's criteria. Average healing time was 13.69 weeks (range 12- 28 weeks). Mean knee range of motion was 122.60° (range 110°-130°). Forty seven results were scored as excellent, 25 good, 2 fair, and 1 as poor. CONCLUSION We believe that minimally invasive treatment by percutaneous techniques and external fixation is a fairly reasonable treatment alternative, if near anatomical reduction of joint surface can be confirmed on fluoroscopy.

Abstract
The rehabilitation of patients following maxillary & mandibular resection is challenging. A prosthesis supported with dental implants is often the treatment of choice, but implants cannot be used predictably in all clinical situations. A tissue supported post resection denture is usually the most acceptable treatment option left in these situations. This case report describes management of a patient who had undergone segmental mandibulectomy & subsequently rehabilitated with resection denture prosthesis. Conventional treatment planning was modified at various stages of fabrication to improve the quality of the final prosthesis.

Abstract
X-ray phase-contrast imaging has emerged as an important method for improving contrast and sensitivity in the field of X-ray imaging. This increase in the sensitivity is attributed to the fact that, in the hard X-ray regime, the phase shift is more prominent as compared with the attenuation for materials having a low X-ray absorption coefficient. Among all the methods using the X-ray phase-contrast technique, in-line phase-contrast imaging scores over the other methods in terms of ease of implementation and efficient use of available X-ray flux. In order to retrieve the projected phase map of the object from the recorded intensity pattern, a large number of algorithms have been proposed. These algorithms generally use either the transport of intensity or contrast transfer function based approach for phase retrieval. In this paper it is proposed to use multiple wavelengths for phase retrieval using the contrast transfer function based formalism.

Abstract
Brown-Séquard syndrome is an uncommon condition involving incomplete spinal cord injury, with ipsilateral motor and proprioception loss, contralateral pain, and decreased temperature. Brown-Séquard-plus syndrome is associated with additional neurologic findings involving the eyes, bowel, or bladder. We describe an adolescent with Brown-Séquard-plus syndrome attributable to a stab injury. Our patient's clinical features of spinal and neurogenic shock overlapped at presentation. He was managed with high-dose steroids, along with intense physiotherapy and rehabilitation, resulting in good neurologic recovery. Appropriate medical (and surgical, when indicated) management usually results in good to complete recovery of neurologic function, depending on the level and grade of injury. With the increasing incidence of gunshot wounds and stab injuries in children, pediatricians, including pediatric neurologists and emergency physicians, are more likely to encounter these types of spinal cord injuries in children.

Abstract
Rapid industrialization and urbanization release several chemicals such as phthalates into the environment and cause adverse effects on reproductive system, mainly endocrine disruption, testicular injury and decline in semen quality in humans. There are no reports in extrapolating of the epidemiological data with in vitro findings. Our study show the correlations between in vivo studies and in vitro data for the effect of phthalate esters. Healthy human males, in the age group 21 to 40 years, visiting Chhatrapati Sahuji Maharaj Medical University (CSMMU), Lucknow, as part of infertility investigation, were recruited as volunteers. Semen analysis was performed according to the WHO guidelines. Phthalate esters were analyzed by high-performance liquid chromatography (HPLC) and cell viability by MTT assay. In the in vitro studies, sperms were exposed to highest concentration in semen samples (5—10 times higher) for a period ranging between 30 min and 96 hours. An inverse relationship with sperm motility in epidemiological studies was concurrent by significant dose-and time-dependent decrease in the sperm motility under in vitro environment after 12-hour exposure. Cytotoxicity was observed only with the highest concentration after 96 hours of exposure. There are a significant correlation between phthalate ester diethylhexyl phthalate, di-n-butyl phthalate (DEHP and DBP) and sperm motility both in vitro and in vivo conditions. Additionally, in vitro experiments conducted not only adjunct to the existing in vivo data but also specify the effect of specific toxicants (DEHP and DBP) on sperm motility and viability. Results show the decrease in motility of sperms under in vitro conditions at the maximum range of in vivo measured levels and 5- or 10-folds higher to that found in human semen samples.

Abstract
Context: The preferential occurrence of idiopathic central serous chorioretinopathy (ICSC) in males with a typical Type A personality and behavior and a relative absence in females is a possible indicator towards the role of serum cortisol and /or the male sex hormone testosterone. Aims: To study levels of cortisol and testosterone in ICSC. Settings and Design: Case-control study in a tertiary care teaching hospital. Materials and Methods: The study was conducted on 23 cases of ICSC. Twelve patients with unilateral sudden painless loss of vision of less than one month duration served as controls. Serum cortisol and testosterone levels at 8.00 a.m. were estimated by radioimmunoassay in both groups. Statistical analysis used: Statistical analysis was done using SPSS 13.0 software. Independent Sample t-test was applied to analyze statistical significance between the two groups. Results: Mean age of patients with ICSC was 37.1 ± 9.7 years and 96% of the patients were males. Mean serum cortisol levels were significantly higher (P=0.002) in patients with ICSC i.e., 495.02 ± 169.47 nano moles/liter (nmol/L) as compared to controls i.e., 362.25 ± 51.54 nmol/L. Mean serum testosterone levels were 3.85 ± 1.81 nano grams/ml (ngm/ml) and 4.23 ± 1.89 ngm/ml in cases and controls respectively and the difference was not statistically significant (P=0.58). Conclusions: ICSC is associated with elevated 8.00 a.m. serum cortisol levels. However, mean serum testosterone levels in both patients of ICSC and controls were within normal range.

Abstract
The objective of the study was to determine the prevalence of domestic violence (DV) in women attending an antenatal clinic in a Delhi hospital; to investigate any associated risk factors; main perpetrators; forms and severity of violence. An anonymous validated questionnaire was used. A total of 26.9% of women reported physical abuse. Emotional and sexual abuse was reported by 29% and 6.2%, respectively. The prevalence of DV was similar in women from different religions or age groups. The prevalence was higher in the poor, less educated and in women who had witnessed abuse. The husband was the main perpetrator (47.4%); other family members were responsible in 31%. The majority of women (69%) reported to have no control over their lives. In addition, the majority of the women did not contribute to major family decisions.

Abstract
In-line x-ray phase contrast is an emerging x-ray imaging technique that promises to improve the contrast in x-ray imaging process. This technique is most suited for x-ray imaging of soft materials, low atomic number elements such as carbon composite fibers, very thin coatings, etc. We have used this new emerging technique for visualization and characterization of the pyrocarbon coated materials using a combination of microfocus x-ray source and x-ray charge coupled device detector. These studies are important for characterization of coating and optimization of various process parameters during deposition. These experiments will help us to exploit the potential of this technique for studies in other areas of material science such as characterization of carbon fibered structures and detection of cracks and flaws in materials. The characterization of the imaging system and optimization of some process parameters for carbon deposition are also described in detail.
