1.  Refolding of β-Stranded Class I Chitinases of Hippophae rhamnoides Enhances the Antifreeze Activity during Cold Acclimation 
PLoS ONE  2014;9(3):e91723.
Class I chitinases hydrolyse the β-1,4-linkage of chitin and also acquire antifreeze activity in some of the overwintering plants during cold stress. Two chitinases, HrCHT1a of 31 kDa and HrCHT1b of 34 kDa, were purified from cold acclimated and non-acclimated seabuckthorn seedlings using chitin affinity chromatography. 2-D gels of HrCHT1a and HrCHT1b showed single spots with pIs 7.0 and 4.6 respectively. N-terminal sequence of HrCHT1b matched with the class I chitinase of rice and antifreeze proteins while HrCHT1a could not be sequenced as it was N-terminally blocked. Unlike previous reports, where antifreeze activity of chitinase was cold inducible, our results showed that antifreeze activity is constitutive property of class I chitinase as both HrCHT1a and HrCHT1b isolated even from non-acclimated seedlings, exhibited antifreeze activity. Interestingly, HrCHT1a and HrCHT1b purified from cold acclimated seedlings, exhibited 4 and 2 times higher antifreeze activities than those purified from non-acclimated seedlings, suggesting that antifreeze activity increased during cold acclimation. HrCHT1b exhibited 23–33% higher hydrolytic activity and 2–4 times lower antifreeze activity than HrCHT1a did. HrCHT1b was found to be a glycoprotein; however, its antifreeze activity was independent of glycosylation as even deglycosylated HrCHT1b exhibited antifreeze activity. Circular dichroism (CD) analysis showed that both these chitinases were rich in unusual β-stranded conformation (36–43%) and the content of β-strand increased (∼11%) during cold acclimation. Surprisingly, calcium decreased both the activities of HrCHT1b while in case of HrCHT1a, a decrease in the hydrolytic activity and enhancement in its antifreeze activity was observed. CD results showed that addition of calcium also increased the β-stranded conformation of HrCHT1a and HrCHT1b. This is the first report, which shows that antifreeze activity is constitutive property of class I chitinase and cold acclimation and calcium regulate these activities of chitinases by changing the secondary structure.

2.  Prevalence and Correlates of Insomnia and Obstructive Sleep Apnea in Chronic Kidney Disease 
Background:
Poor sleep quality, insomnia, and restless legs syndrome (RLS) and sleep apnea are common in patients with chronic kidney disease (CKD). Clinical correlates of these problems are poorly understood.
Aims:
This study was to find out the prevalence and correlates of insomnia and subjects with ‘high risk for obstructive sleep apnea (OSA)’ in adults with chronic kidney disease.
Materials and Methods:
One hundred and four adults with CKD were included. Their demographic data, details regarding kidney disease and hemodialysis (HD) were recorded. Presence of insomnia and its severity was assessed. They were screened for sleep apnea using a validated questionnaire.
Results:
Average age was 54.17 (± 12.96) years. 89.4% had stage 5 nephropathy and 78.8% subjects were on regular HD. Males outnumbered females. Insomnia was reported by 35.5%. Among these, 50% had chronic insomnia. Insomnia subjects had higher prevalence of diabetes (P = 0.01) and depression (P < 0.001). Fifty-one percent subjects were at “high risk for sleep apnea”. They had higher prevalence of diabetes (P < 0.001), coronary disease (P = 0.02), insomnia (P = 0.008), and experienced daytime symptoms of insomnia (P < 0.001). However, in the logistic regression, only male gender (odds ratio, OR = 13.59) and daytime symptoms of insomnia (OR = 7.34) were found to be associated with “higher risk for sleep apnea”.
Conclusion:
Insomnia was prevalent in CKD. Nearly half of these patients are at high risk for sleep apnea and a third of them suffer from insomnia. Hence, these patients should be screened for sleep disorders.

4.  CTCF binding site sequence differences are associated with unique regulatory and functional trends during embryonic stem cell differentiation 
Nucleic Acids Research  2013;42(2):774-789.
CTCF (CCCTC-binding factor) is a highly conserved multifunctional DNA-binding protein with thousands of binding sites genome-wide. Our previous work suggested that differences in CTCF’s binding site sequence may affect the regulation of CTCF recruitment and its function. To investigate this possibility, we characterized changes in genome-wide CTCF binding and gene expression during differentiation of mouse embryonic stem cells. After separating CTCF sites into three classes (LowOc, MedOc and HighOc) based on similarity to the consensus motif, we found that developmentally regulated CTCF binding occurs preferentially at LowOc sites, which have lower similarity to the consensus. By measuring the affinity of CTCF for selected sites, we show that sites lost during differentiation are enriched in motifs associated with weaker CTCF binding in vitro. Specifically, enrichment for T at the 18th position of the CTCF binding site is associated with regulated binding in the LowOc class and can predictably reduce CTCF affinity for binding sites. Finally, by comparing changes in CTCF binding with changes in gene expression during differentiation, we show that LowOc and HighOc sites are associated with distinct regulatory functions. Our results suggest that the regulatory control of CTCF is dependent in part on specific motifs within its binding site.

7.  Pucker sign in proximal humeral fractures: implications on management 
Fracture of the surgical neck of humerus in young patients is a relatively rare injury. We reviewed the available material on the topic and identified puckering at the shoulder in high-energy fracture of the surgical neck as a finding which has been reported infrequently but signifies a need for open reduction. We present a review of the literature on the subject and our similar experience in two young males who had puckering and ecchymosis at the shoulder.

8.  Resuscitation Promoting Factors: a Family of Microbial Proteins in Survival and Resuscitation of Dormant Mycobacteria 
Indian Journal of Microbiology  2011;52(2):114-121.
Mycobacterium tuberculosis, the causative agent of tuberculosis (TB), is an extraordinarily successful pathogen of humankind. It has been estimated that up to one-third of the world’s population is infected with M. tuberculosis, and this population is an important reservoir for disease reactivation. Resuscitation promoting factor (Rpf) is a secretory protein, which was first reported in Micrococcus luteus. There are five functionally redundant Rpf-like proteins found in M. tuberculosis. Rpf promotes the resuscitation of dormant bacilli to yield normal, viable colony forming bacteria. All Rpfs share a conserved domain of about 70 amino acids and possess a lysozyme-like activity. The structural studies of the conserved domain suggest that Rpfs could be considered as a c-type lysozyme and lytic transglycosylases. Recently a novel class of nitrophenylthiocyanates (NPT) inhibitors of the muralytic activity of Rpf were reported which opens a new approach in the study of cell-wall hydrolyzing enzymes. This review describes molecular and structural studies conducted on Rpf proteins, their role in the resuscitation of dormant bacteria, in the reactivation of latent infection and identification of low molecular weight inhibitors of resuscitation promoting factors.

9.  Prevalence of obstructive sleep apnea in surgical patients presenting to a tertiary care teaching hospital in India: A preliminary study 
Saudi Journal of Anaesthesia  2013;7(2):155-159.
Background:
Obstructive sleep apnea (OSA) is often not diagnosed in patients presenting for surgical procedures thereby increasing the incidence of adverse perioperative course. Early diagnosis of this disease is important in modifying anesthetic management as well as utilizing specific means which may decrease the complications and improve the patient outcome.
Methods:
Patients greater than eighteen years of age, ASA I-III scheduled for elective surgical procedures under anesthesia were randomly selected. Their demographic data, diagnosis and nature of surgery were noted in a semi-structured performa. They were then screened for the presence of OSA with the help of a STOP BANG questionnaire.
Results:
This study included two hundred four patients randomly selected. Slight female predominance was seen in this sample (55.4%). Mean age of the subjects was 42.7 years (SD=15.08). 24.5% subjects were at high risk for OSA (STOP-BANG>3) with a male predominance (72% versus 37% in low risk group; X2=18.62; P<0.001). High risk OSA subjects had higher prevalence of cardiovascular risk factors (57% vs. 11.7% in low risk group; X2=33.35; P<0.001). Similarly, this group had a higher prevalence of asthma and chronic obstructive pulmonary disease (COPD) (14% versus 3.8% in low risk group; X2=6.54; P=0.03). Prevalence of diabetes mellitus (22%) and hypothyroidism (6%) was also higher in this group (5.2% and 1.9% in low risk group respectively; X2=15.42; P<0.001).
Conclusion:
High degree of suspicion and knowledge of association of OSA and medical diseases may help in detection of such cases and decrease the rate of perioperative complications thus improving patients safety.

10.  Conservative Management of Chronic Aortic Dissection with Underlying Aortic Aneurysm 
Heart International  2013;8(1):e4.
Aortic dissection is one of the most common aortic emergencies affecting around 2000 Americans each year. It usually presents in the acute state but in a small percentage of patients aortic dissections go unnoticed and these patients survive without any adequate therapy. With recent advances in medical care and diagnostic technologies, aortic dissection can be successfully managed through surgical or medical options, consequently increasing the related survival rate. However, little is known about the optimal long-term management of patients suffering from chronic aortic dissection. The purpose of the present report is to review aortic dissection, namely its pathology and the current diagnostic tools available, and to discuss the management options for chronic aortic dissection. We report a patient in which chronic aortic dissection presented with recurring episodes of vomiting and also discuss the management plan of our patient who had a chronic aortic dissection as well as an underlying aortic aneurysm.

11.  Prevalence of restless leg syndrome in subjects with depressive disorder 
Indian Journal of Psychiatry  2013;55(1):70-73.
Background:
Restless legs syndrome (RLS) is known to be associated with depression. We hypothesized that RLS in depression is linked to the severity, duration, and frequency of depressive episodes.
Materials and Methods:
Subjects fulfilling DSM-IV-TR criteria of depressive disorders were included in this study after seeking informed consent. Using structured interview of MINI-Plus their demographic data and history were recorded. Severity of depression was assessed with the help of HAM-D. Insomnia was diagnosed following ICSD-2 criteria. RLS was diagnosed according to IRLSSG criteria. Descriptive statistics, Chi-square test, independent sample t test and MANOVA were computed with the help of SPSS v 17.0.
Results:
RLS was reported by 31.48% of sample. There was no gender difference in prevalence of RLS (X2 =0.46; P=0.33). There was no difference in the age , total duration of depressive illness and number of depressive episodes between RLS and non-RLS groups (F=0.44; P=0.77; Wilk's Lambda=0.96). The HAM-D score was higher in the non-RLS group (P=0.03). Onset of RLS symptoms was not related to onset of depressive symptoms.
Conclusion:
RLS is prevalent in depressive disorder. However, onset of RLS is unrelated to age and number or duration of depressive disorders.

14.  Estimation of Gene Expression at Isoform Level from mRNA-Seq Data by Bayesian Hierarchical Modeling 
Frontiers in Genetics  2012;3:239.
mRNA-Seq is a precise and highly reproducible technique for measurement of transcripts levels and yields sequence information of a transcriptome at a single nucleotide base-level thus enabling us to determine splice junctions and alternative splicing events with high confidence. Often analysis of mRNA-Seq data does not attempt to quantify the expressions at isoform level. In this paper our objective would be use the mRNA-Seq data to infer expression at isoform level, where splicing patterns of a gene is assumed to be known. A Bayesian latent variable based modeling framework is proposed here, where the parameterization enables us to infer at various levels. For example, expression variability of an isoform across different conditions; the model parameterization also allows us to carry out two-sample comparisons, e.g., using a Bayesian t-test, in addition simple presence or absence of an isoform can also be estimated by the use of the latent variables present in the model. In this paper we would carry out inference on isoform expression under different normalization techniques, since it has been recently shown that one of the most prominent sources of variation in differential call using mRNA-Seq data is the normalization method used. The statistical framework is developed for multiple isoforms and easily extends to reads mapping to multiple genes. This could be achieved by slight conceptual modifications in definitions of what we consider as a gene and what as an exon. Additionally proposed framework can be extended by appropriate modeling of the design matrix to infer about yet unknown novel transcripts. However such attempts should be made judiciously since the input date used in the proposed model does not use reads from splice junctions.

16.  Supratentorial primitive neuroectodermal tumor in an adult: a case report and review of the literature 
Introduction
Supratentorial primitive neuroectodermal tumors predominantly occur in children, and are rare in the adult population. Less than 100 cases of supratentorial primitive neuroectodermal tumor have been reported in adults internationally. Our case study reports this rare incident.
Case presentation
A 22-year-old Hispanic man presented with headaches, blurry vision, diplopia, intermittent vomiting, and grossly decreased vision. A magnetic resonance image showed a left posterior parietal heterogeneously enhancing mass measuring 4.2cm × 7.2cm × 7.0cm. After craniotomy for resection and decompression, the mass was histologically revealed to be a supratentorial primitive neuroectodermal tumor. Standardized immunohistochemical studies for this mass were carried out.
Conclusion
We have concluded that immunohistochemical and genetic workup should be included in the standardized pathological workup for primitive neuroectodermal tumors in order to provide more prognostic information. Based on our current literature review, we propose an immunohistochemical panel.

18.  Sequencing and analysis of a South Asian-Indian personal genome 
BMC Genomics  2012;13:440.
Background
With over 1.3 billion people, India is estimated to contain three times more genetic diversity than does Europe. Next-generation sequencing technologies have facilitated the understanding of diversity by enabling whole genome sequencing at greater speed and lower cost. While genomes from people of European and Asian descent have been sequenced, only recently has a single male genome from the Indian subcontinent been published at sufficient depth and coverage. In this study we have sequenced and analyzed the genome of a South Asian Indian female (SAIF) from the Indian state of Kerala.
Results
We identified over 3.4 million SNPs in this genome including over 89,873 private variations. Comparison of the SAIF genome with several published personal genomes revealed that this individual shared ~50% of the SNPs with each of these genomes. Analysis of the SAIF mitochondrial genome showed that it was closely related to the U1 haplogroup which has been previously observed in Kerala. We assessed the SAIF genome for SNPs with health and disease consequences and found that the individual was at a higher risk for multiple sclerosis and a few other diseases. In analyzing SNPs that modulate drug response, we found a variation that predicts a favorable response to metformin, a drug used to treat diabetes. SNPs predictive of adverse reaction to warfarin indicated that the SAIF individual is not at risk for bleeding if treated with typical doses of warfarin. In addition, we report the presence of several additional SNPs of medical relevance.
Conclusions
This is the first study to report the complete whole genome sequence of a female from the state of Kerala in India. The availability of this complete genome and variants will further aid studies aimed at understanding genetic diversity, identifying clinically relevant changes and assessing disease burden in the Indian population.

19.  Primary headaches in restless legs syndrome patients 
Annals of Indian Academy of Neurology  2012;15(Suppl 1):S104-S108.
Earlier studies conducted among migraineurs have shown an association between migraine and restless legs syndrome (RLS). We chose RLS patients and looked for migraine to exclude sample bias.
Materials and Methods:
99 consecutive subjects of idiopathic RLS were recruited from the sleep clinic during four months period. Physician diagnosis of headache and depressive disorder was made with the help of ICHD-2 and DSM-IV-TR criteria, respectively. Sleep history was gathered. Severity of RLS and insomnia was measured using IRLS (Hindi version) and insomnia severity index Hindi version, respectively. Chi-square test, one way ANOVA and t-test were applied to find out the significance.
Results:
Primary headache was seen in 51.5% cases of RLS. Migraine was reported by 44.4% subjects and other types of ‘primary headaches’ were reported by 7.1% subjects. Subjects were divided into- RLS; RLS with migraine and RLS with other headache. Females outnumbered in migraine subgroup (χ2=16.46, P<0.001). Prevalence of depression (χ2=3.12, P=0.21) and family history of RLS (χ2=2.65, P=0.26) were not different among groups. Severity of RLS (P=0.22) or insomnia (P=0.43) were also similar.
Conclusion:
Migraine is frequently found in RLS patients in clinic based samples. Females with RLS are prone to develop migraine. Depression and severity of RLS or insomnia do not affect development of headache.

20.  Adult rumination syndrome: Differentiation from psychogenic intractable vomiting 
Indian Journal of Psychiatry  2012;54(3):283-285.
Rumination syndrome is known to exist in infants and mentally retarded adults since long time. In past few years, some reports appeared that showed its existence in adult patients also. It is frequently confused with the intractable vomiting in adults and misdiagnosis leads to delay in appropriate management. We are here describing the case of a female patient with rumination syndrome where specific points in the history delineated the presence of this illness and helped in appropriate management. The patient became symptom free soon after the diagnosis was reached.

21.  Repair of the torn distal biceps tendon by endobutton fixation 
Indian Journal of Orthopaedics  2012;46(1):71-76.
Background:
A number of techniques have been described to reattach the torn distal biceps tendon to the bicipital tuberosity. We report a retrospective analysis of single incision technique using an endobutton fixation in sports persons.
Materials and Methods:
The present series include nine torn distal biceps tendons in eight patients, fixed anatomically to the radial tuberosity with an endobutton by using a single incision surgical technique; seven patients had suffered the injuries during contact sports. The passage of the endobutton was facilitated by using a blunt tipped pin in order to avoid injury to the posterior interosseous nerve. The patients were evaluated by Disabilities of the Arm, Shoulder and Hand (DASH) score and Mayo elbow score.
Results:
The average age of the patients was 27.35 years (range 21–42 years). Average follow-up was 41.5 months (range 24–102 months). The final average flexion extension arc was 0°–143°, while the average pronation and supination angles were 77° (range 70°–82°) and 81° (range 78°–85°), respectively at the last followup. All the patients had a Disabilities of the Arm, Shoulder and Hand (DASH) score of 0 and a Mayo elbow score of 100 each. All the seven active sports persons were able to get back to their respective game. There was no nerve injury or any other complication.
Conclusions:
The surgical procedure used by us is a simple, safe and reproducible technique giving minimal morbidity and better cosmetic results.

22.  Antibiotic Resistance Pattern of Community Acquired Uropathogens at a Tertiary Care Hospital in Jaipur, Rajasthan 
Background:
Urinary tract infections (UTIs) are amongst the most common infections described in outpatients setting.
Objectives:
A study was conducted to evaluate the uropathogenic bacterial flora and its antimicrobial susceptibility profile among patients presenting to the out-patient clinics of a tertiary care hospital at Jaipur, Rajasthan.
Materials and Methods:
2012 consecutive urine specimens from symptomatic UTI cases attending to the outpatient clinics were processed in the Microbiology lab. Bacterial isolates obtained were identified using biochemical reactions. Antimicrobial susceptibility testing was performed by the Kirby-Bauer disc diffusion method. Extended spectrum beta lactamase (ESBL) production was determined by the double disk approximation test and the Clinical and Laboratory Standards Institute (formerly NCCLS) confirmatory method.
Results:
Pathogens were isolated from 346 (17.16%) of the 2012 patients who submitted a urine sample. Escherichia coli was the most frequently isolated community acquired uropathogen accounting for 61.84% of the total isolates. ESBL production was observed in 23.83% of E. coli strains and 8.69% of Klebsiella strains. With the exception of Nitrofurantoin, resistance to agents commonly used as empiric oral treatments for UTI was quite high.
Conclusion:
The study revealed E. coli as the predominant bacterial pathogen for the community acquired UTIs in Jaipur, Rajasthan. An increasing trend in the production ESBLs among UTI pathogens in the community was noted. Nitrofurantoin should be used as empirical therapy for primary, uncomplicated UTIs.

23.  Migraine: Clinical pattern and psychiatric comorbidity 
Industrial Psychiatry Journal  2012;21(1):18-21.
Background:
Migraine is a common disorder which has psychiatric sequelae.
Objective:
The objective of this study was to determine the clinical pattern and psychiatric comorbidity of migraine.
Materials and Methods:
100 cases of migraine seen over a period of one year were analysed to know the sociodemographic characteristics, clinical pattern and psychiatric morbidity.
Results:
Maximum patients were between 31-40 years of age group (40%), females (78.0%), married (76%) and housewives (56.0%). Family history of migraine was present in 12% cases. Average age of onset was 22 years. Unilateral and throbbing type of headache was most common. The commonest frequency was one to two per week. Migraine without aura was commonest sub-type (80%). Generalized anxiety disorder (F41.1) was the most common psychiatric disorder (34%), followed by mixed anxiety and depressive disorder (F41.2) (18%) and depressive episode (F32) (14%). In 22% cases, no psychiatric disorder could be elicited.
Conclusion:
The present study confirms that majority patients with migraine had psychiatric disorders. This needs timely detection and appropriate intervention to treat and control the migraine effectively.

24.  Papillary Carcinoma of the Breast: An Overview 
Papillary carcinoma of the breast represents approximately 0.5% of all newly diagnosed cases of breast cancer. The prevalence of both invasive and in situ papillary carcinoma seems to be greater older postmenopausal women, and -in relative terms-in males. Histologic features of the tumor include cellular proliferations surrounding fibrovascular cores, with or without invasion. In this review, characteristics of both in situ and invasive disease are outlined. Immunohistochemical analyses of papillary carcinoma suggest the utility of markers such as smooth muscle myosin heavy chain, calponin, p63 and high molecular weight keratins, which can characterize the myoepithelial cell layer. With respect to radiographic evaluation of papillary carcinoma, ultrasonography is the most extensively studied imaging modality, though magnetic resonance mammography has potential utility. Available data suggest improved outcome for papillary carcinoma as compared to invasive ductal carcinoma. Treatment-related information for patients with papillary carcinoma is limited, and patterns noted in available series suggest a variable approach to this disease. The scarcity of information underscores the need for further treatment- and outcome-related studies in papillary carcinoma of the breast.

25.  Translation and validation of International Restless Leg Syndrome Study Group rating scale in Hindi language 
Objectives:
The objective of this study is to translate and validate the International Restless Leg Syndrome Study Group rating scale (IRLS) in Hindi language.
Materials and Methods:
Thirty one consecutive patients diagnosed of Restless Leg Syndrome (RLS) were included in the study. Control group comprised of 31 subjects not having any symptom of RLS. The scale was procured from MAPI research trust; and, permission for the translation was sought. The translation was done according to the guidelines provided by the publisher. After translation, final version of the scale was applied in both the groups to find out the reliability and clinical validity.
Results:
RLS group had a predominance of females, and they were younger than the male counterparts (Age=36.80 ± 10.46 years vs 45.18 ± 8.34 years; t=2.28; P=0.03). There was no difference in the mean age between groups (RLS=39.77 ± 10.44 years vs Non RLS=38.29 ± 11.29 years; t=-0.53; P=0.59). IRLS scores were significantly different between both groups on all items (P<0.001). Translated version showed high reliability (Cronbach's alpha=0.86). IRLS scores were significantly different between both groups on all items (P<0.001).
Conclusion:
Hindi version of IRLS is reliable and a clinically valid tool that can be applied in Hindi speaking population.
