Abstract
Cat scratch disease is caused by Bartonella henselae and usually manifests as localized lymphadenopathy and fever in immunocompetent patients. Immunocompromised patients are at risk for developing disseminated disease affecting the liver, spleen, eyes, central nervous system, and other organs. Bartonellosis is infrequently reported in solid organ transplant recipients, and published case reports usually discuss disseminated infection. Localized ocular disease with B. henselae, while well documented in immunocompetent hosts, is uncommon in immunocompromised patients. Herein, we present 2 cases of ocular bartonellosis in renal transplant patients, 1 with disseminated infection, and 1 without.

Abstract
BACKGROUND The prevalence of eczema is increasing in industrialized nations. Limited evidence has shown the association of DNA methylation (DNA-M) with eczema. We explored this association at the epigenome-scale to better understand the role of DNA-M. Data from the first generation (F1) of the Isle of Wight (IoW) birth cohort participants and the second generation (F2) were examined in our study. Epigenome-scale DNA methylation of F1 at age 18 years and F2 in cord blood was measured using the Illumina Infinium HumanMethylation450 Beadchip. A total of 307,357 cytosine-phosphate-guanine sites (CpGs) in the F1 generation were screened via recursive random forest (RF) for their potential association with eczema at age 18. Functional enrichment and pathway analysis of resulting genes were carried out using DAVID gene functional classification tool. Log-linear models were performed in F1 to corroborate the identified CpGs. Findings in F1 were further replicated in F2. RESULTS The recursive RF yielded 140 CpGs, 88 of which showed statistically significant associations with eczema at age 18, corroborated by log-linear models after controlling for false discovery rate (FDR) of 0.05. These CpGs were enriched among many biological pathways, including pathways related to creating transcriptional variety and pathways mechanistically linked to eczema such as cadherins, cell adhesion, gap junctions, tight junctions, melanogenesis, and apoptosis. In the F2 generation, about half of the 83 CpGs identified in F1 showed the same direction of association with eczema risk as in F1, of which two CpGs were significantly associated with eczema risk, cg04850479 of the PROZ gene (risk ratio (RR) = 15.1 in F1, 95 % confidence interval (CI) 1.71, 79.5; RR = 6.82 in F2, 95 % CI 1.52, 30.62) and cg01427769 of the NEU1 gene (RR = 0.13 in F1, 95 % CI 0.03, 0.46; RR = 0.09 in F2, 95 % CI 0.03, 0.36). CONCLUSIONS Via epigenome-scaled analyses using recursive RF followed by log-linear models, we identified 88 CpGs associated with eczema in F1, of which 41 were replicated in F2. Several identified CpGs are located within genes in biological pathways relating to skin barrier integrity, which is central to the pathogenesis of eczema. Novel genes associated with eczema risk were identified (e.g., the PROZ and NEU1 genes).

Abstract
BACKGROUND Increasing population, fast paced industrialization, increased, competitiveness, unanticipated problems in the work place have increased the stress among the females working in health care in recent times. AIM The aim of the following study is to detect the stress levels among female health care professionals in the age group of 25-35 years and its impact on health. SUBJECTS AND METHODS A prospective cross-sectional pilot project was conducted in a tertiary care hospital in Eastern part of India, after receiving approval from the Institutional Ethics Committee and informed consent form was taken from the subjects. Stress level in the subjects was assessed according to the presumptive life event stress scale. Females with scores above 200 were selected. For these, initial assessment of anthropometric measurement, electrocardiogram and lipid profile analysis, resting pulse rate, blood pressure, physical fitness index (PFI), breath holding time (BHT), isometric hand grip (IHG) test results were evaluated and recorded. All subjects were given training of progressive muscle relaxation (PMR) for 3 months. After 3 months, the lipid profile and vital parameters, Perceived Stress Scale values were re-evaluated and subjects were asked to repeat the same exercises and data thus recorded were analyzed using Statistical Package for the Social Sciences (SPSS) version 16 (SPSS Inc. Released 2007. SPSS for Windows, Version 16.0. Chicago, SPSS Inc.). RESULTS Significant decrease in resting heart rate, blood pressure and Perceived Stress Scale levels was seen after PMR training in the subjects. Results of BHT, IHG tests and PFI were significantly increased after PMR training. There was a significant decrease in total cholesterol, triglyceride and low-density lipoprotein cholesterol in subjects after practicing PMR for 3 months. CONCLUSIONS Increasing stress among female health care professionals is a cause for concern and there is a need to adopt early life-style modification by practicing relaxation exercises to ameliorate stress and to improve not only their quality-of-life in general, but patient care in particular.

Abstract
BACKGROUND Sarcoidosis associated hypercalcemia (SAHC) may be secondary to excessive levels of 1,25-(OH)2 vitamin D3 produced by autonomous 1-alpha-hydroxylase activity within the granulomas. The frequency, treatment, and consequences of hypercalcemia remain unclear. STUDY DESIGN AND METHODS Two patient cohorts were studied. In Cohort 1, the prevalence of hypercalcemia in 1606 sarcoidosis patients seen during a six year period was analyzed along with treatment and outcome. Cohort 2 consisted of 261 sarcoidosis patients with measured 25-(OH) vitamin D3 and 1,25-(OH) vitamin D3 levels. In forty patients, serial levels of 25-(OH) vitamin D3 and 1,25-(OH) vitamin D3 were measured at least three months apart without change in therapy. RESULTS SAHC was identified in 97 of 1606 (6%) of patients studied and additional nine (0.6%) patients had primary hyperparathyroidism. Post treatment follow up was available in 86 SAHC patients. Hypercalcemia improved in >90% of patients, including eight patients treated solely with vitamin D supplement withdrawal. Renal insufficiency, documented in 41 (42%) of SAHC patients, improved with hypercalcemia treatment. In 80% of Cohort 2 patients low 25-(OH) vitamin D3 levels were measured with only one patient having a low 1,25(OH)2 vitamin D3 level. Elevated 1,25(OH)2 vitamin D3 levels, which were measured in 11% of patients, were higher for those with a history of hypercalcemia. CONCLUSION Sarcoidosis associated hypercalcemia, which is often accompanied by renal insufficiency, responds to treatment of sarcoidosis and withdrawal of vitamin D supplementation. Measurement of serum vitamin 1,25(OH)2 vitamin D3 appears to best evaluate vitamin D status in sarcoidosis patients.

Abstract
BACKGROUND Hyperoxia or clinical oxygen (O2) therapy is known to result in increased oxidative burden. Therefore, understanding susceptibility to hyperoxia exposure is clinically important. Bone morphogenetic proteins (BMPs) 2 and 4 are involved in cardiac development and may influence responses to hyperoxia. METHODS Bmp2(+/)(-). Bmp4(+/)(-) and wild-type mice were exposed to hyperoxia (100% O2) for 24 hrs. Electrocardiograms (ECG) were recorded before and during exposure by radio-telemetry. RESULTS At baseline, a significantly higher low frequency (LF) and total power (TP) heart rate variability (HRV) were found in Bmp2(+/)(-) mice only (p < 0.05). Twenty-four hours hyperoxia-induced strain-independent reductions in heart rate, QTcB and ST-interval and increases in QRS, LF HRV and standard deviation of RR-intervals were observed. In Bmp4(+/)(-) mice only, increased PR-interval (PR-I) (24 hrs), P-wave duration (P-d; 18 and 21-24 hrs), PR-I minus P-d (PR - Pd; 24 hrs) and root of the mean squared differences of successive RR-intervals (24 hrs) were found during hyperoxia (p < 0.05). DISCUSSION Elevated baseline LF and TP HRV in Bmp2(+/)(-) mice suggests an altered autonomic nervous system regulation of cardiac function in these mice. However, this was not related to strain specific differences in responses to 24 hrs hyperoxia. During hyperoxia, Bmp4(+/-) mice were the most susceptible in terms of atrioventricular conduction changes and risk of atrial fibrillation, which may have important implications for patients treated with O2 who also harbor Bmp4 mutations. This study demonstrates significant ECG and HRV responses to 24 hrs hyperoxia in mice, which highlights the need to further work on the genetic mechanisms associated with cardiac susceptibility to hyperoxia.

Abstract
Nursing personnel are the largest deliverer of health care worldwide, responsible for the constant care of in-patients. They are the most important link between doctors and patients. This study evaluated the knowledge, attitudes and practices of nursing students about different health care related aspects, which must have a profound impact on the quality service of any health care setup. Nursing students from a tertiary care teaching hospital from West Bengal, India were interviewed using a semi-structured pretested questionnaire. The subjects had sound knowledge regarding malaria, HIV disease transmission; possess positive attitude and good practices about medications. There was increased tendency of self-medication, which was alarming. The study showed improvement in knowledge of the nursing students during their nursing curriculum. It is clear from the present study that the efforts in spreading the knowledge about medicaments and disease have met with success to some extent. Furthermore tremendous effort has to be taken to convert the theoretical knowledge into 'safe practices'.

Abstract
Protein hydrolysates as substitutes for serum havebeen employed by many in cell culture mediumformulation, especially with the shift to low proteinor protein-free media. More recently, vegetablehydrolysates have also been added as nutritionalsupplements to fortify the amino acid content in smallpeptide form for batch and fed-batch fermentations. Several of these new hydrolysates (peptones of soy,rice, wheat gluten etc.) were tested as protein-freemedium supplements for the production of a recombinanttherapeutic protein. Multiple peptone-supplemented,continuous perfusion bioreactor experiments wereconducted, varying dilution rates and basal mediumcomposition over the various runs. Cell specificrates and product quality studies were obtained forthe various peptones and compared with peptone-freemedium. The potential for peptones to decreaseintrinsic and proteolytic degradation of the productwas also investigated.It was found that peptones confer a nutritionalbenefit, especially at low dilution rates, for therecombinant BHK cell line used in this investigation.The specific productivity increased 20-30% comparedto the peptone-free controls. However, this benefitwas also fully delivered by using fortified medium inplace of the peptone-enriched media. Therefore, whilepeptones may be considered as useful medium additiveswhen development time is limited, their addition maybe avoided by systematic medium development ifpermitted by the time line of the project.

Abstract
A 5-month-old male infant presented with weak cry, decreased body movements, tightness of whole body since birth, and one episode of generalized seizure on day 4 of life. He was born at term by elective caesarian section performed for breech presentation. The child had failure to thrive, contractures at elbow and knee joints, hypertonia, microcephaly, small mouth, retrognathia, and camptodactyly. There was global developmental delay. Abdominal examination revealed umbilical and bilateral inguinal hernia. Visual evoked response and brainstem evoked response audiometry were abnormal. Nerve conduction velocity was normal. Magnetic resonance imaging of brain revealed paucity of white matter in bilateral cerebral hemispheres with cerebellar and brain stem atrophy. The differential diagnoses considered in the index patient were distal arthrogryposis (DA) syndrome, cerebroculofacioskeletal syndrome, and Pena Shokier syndrome. The index patient most likely represents a variant of DA: Sheldon Hall syndrome.

Abstract
ABSTRACTESCA valence band and core level loss results have been determined that appear to be directly related to the degree of covalency/ionicity and other bonding features of certain semi-conductor systems. Specific applications are presented that aid in the characterization of the key chemistry of dielectric oxide/semiconductor interfaces and also may help to determine the relative metastability of the solid solution of Group IV elements (e.g., Ge) into certain III-V lattices (e.g., GaAs). It is shown that these features are not detectable through conventional core level shift arguments, and that the aforementioned novel approaches often require high resolution ESCA.

Abstract
In various organisms, an array of enzymes is involved in the synthesis and breakdown of methylglyoxal. Through these enzymes, it is intimately linked to several other physiologically important metabolites, suggesting that methylglyoxal has some important role to play in the host organism. Several in vitro and in vivo studies showed that methylglyoxal acts specifically against different types of malignant cells. These studies culminated in a recent investigation to evaluate a methylglyoxal-based formulation in treating a small group of cancer patients, and the results were promising. Methylglyoxal acts against a number of pathogenic microorganisms. However, recent literature abounds with the toxic effects of methylglyoxal, which are supposed to be mediated through methylglyoxal-derived advanced glycation end products (AGE). Many diseases such as diabetes, cataract formation, hypertension, and uremia are proposed to be intimately linked with methylglyoxal-derived AGE. However methylglyoxal-derived AGE formation and subsequent pathogenesis might be a very minor event because AGE are nonspecific reaction products that are derived through the reactions of carbonyl groups of reducing sugars with amino groups present in the side chains of lysine and arginine and in terminal amino groups of proteins. Moreover, the results of some in vitro experiments with methylglyoxal under non-physiological conditions were extrapolated to the in vivo situation. Some experiments even showed contradictory results and were differently interpreted. For this reason conclusions about the potential beneficial effects of methylglyoxal have often been neglected, thus hindering the advancement of medical science and causing some confusion in fundamental understanding. Overall, the potential beneficial effects of methylglyoxal far outweigh its possible toxic role in vivo, and it should be utilized for the benefit of suffering humanity.

Abstract
Here we describe the purification of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) from normal leukocytes of healthy subjects and leukocytes of chronic myeloid leukemia (CML) patients and from normal mouse muscle and sarcoma tissue. The data indicate that some properties of GAPDH of leukocytes of CML patients and sarcoma tissues are similar and also similar to those of EAC (Ehrlich ascites carcinoma) cellular GAPDH but distinctly different from those of the normal cellular GAPDH. Polyclonal antiserum raised against the 54 kDa subunit of EAC cell GAPDH strongly reacted with GAPDH of leukocytes of CML patients and sarcoma tissue GAPDH only and weakly reacted with GAPDH of normal leukocyte and normal muscle and a variety of other tissues of normal rats. Both the subunits of GAPDH of sarcoma tissues were partially sequenced from the N-terminus and compared with the known sequences of GAPDH. The altered properties of GAPDH of three different malignant sources might be common feature of all malignant cells, which is discussed in relation to glycolysis and malignant aberrations.
