Abstract
Sexual maturation of Anastrepha fraterculus is a long process. Methoprene (a mimic of juvenile hormone) considerably reduces the time for sexual maturation in males. However, in other Anastrepha species, this effect depends on protein intake at the adult stage. Here, we evaluated the mating competitiveness of sterile laboratory males and females that were treated with methoprene (either the pupal or adult stage) and were kept under different regimes of adult food, which varied in the protein source and the sugar:protein ratio. Experiments were carried out under semi-natural conditions, where laboratory flies competed over copulations with sexually mature wild flies. Sterile, methoprene-treated males that reached sexual maturity earlier (six days old), displayed the same lekking behaviour, attractiveness to females and mating competitiveness as mature wild males. This effect depended on protein intake. Diets containing sugar and hydrolyzed yeast allowed sterile males to compete with wild males (even at a low concentration of protein), while brewer´s yeast failed to do so even at a higher concentration. Sugar only fed males were unable to achieve significant numbers of copulations. Methoprene did not increase the readiness to mate of six-day-old sterile females. Long pre-copulatory periods create an additional cost to the management of fruit fly pests through the sterile insect technique (SIT). Our findings suggest that methoprene treatment will increase SIT effectiveness against A. fraterculus when coupled with a diet fortified with protein. Additionally, methoprene acts as a physiological sexing method, allowing the release of mature males and immature females and hence increasing SIT efficiency.

Abstract
Regulatory T cells are essential to maintain immune homeostasis and prevent autoimmunity. Therapy with in vitro expanded human nTRegs is being tested to prevent graft versus host disease, which is a major cause for morbidity and mortality associated with hematopoietic stem cell transplantation. Their usefulness in therapy will depend on their capacity to survive, migrate appropriately and retain suppressive activity when introduced into a transplant recipient. The lack of a suitable animal model for studying the in vivo reconstitutive capability of human nTRegs is a major impediment for investigating the behavior of adoptively transferred nTRegsin vivo. We show that injection of a plasmid encoding human IL-2 is necessary and sufficient for long term engraftment of in vitro expanded nTRegs in NOD-SCID IL2rγcnull mice. We also demonstrate that these in vivo reconstituted TRegs traffic to different organs of the body and retain suppressive function. Finally, in an IL-2 accelerated GVHD model, we show that these in vivo reconstituted TRegs are capable of preventing severe xenogenic response of human PBMCs. Thus, this novel ‘hu-TReg mouse’ model offers a pre-clinical platform to study the in vivo function and stability of human nTRegs and their ability to modulate autoimmune diseases and GVHD.

Abstract
Cells with unique capacity for self-renewal and potency are called stem cells. With appropriate biochemical signals stem cells can be transformed into desirable cells. The idea behind this article is to shortly review the obtained literature on stem cell with respect to their properties, types and advantages of dental stem cells. Emphasis has been given to the possibilities of stem cell therapy in the oral and maxillofacial region including regeneration of tooth and craniofacial defects.

Abstract
OBJECTIVE Previous studies investigating psychiatric comorbidity in eating disorder (ED) patients compared groups according to ED diagnoses. The current paper compared groups according to ED behaviours: self-induced vomiting, objective binge eating, excessive exercising, and to body mass index (BMI, kg/m(2)) for selected psychiatric comorbidity using two systems: Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition (DSM-IV) and International Classification of Diseases - Tenth Revision (ICD-10) diagnoses. METHOD Two hundred and twenty-six patients admitted for treatment in a specialised Eating Disorders Unit completed the Composite International Diagnostic Interview (CIDI). Lifetime and recent (12 months) psychiatric diagnoses were produced according to DSM-IV and ICD-10. Associations between presence of ED behaviours or BMI and psychiatric comorbidity were investigated. RESULTS Eighty-eight percent of patients had a lifetime history (72% recent history) of at least one comorbid diagnosis (regardless of diagnostic system). Agreement between the systems was high for mood (affective) disorders and moderate for anxiety/somatoform disorders. Significantly more patients who vomit had lifetime and recent mood (affective) disorders (DSM-IV and ICD-10). Significantly more 'vomiters' had recent anxiety disorders (DSM-IV) and neurotic, stress-related and somatoform disorders (ICD-10) including post-traumatic stress disorder (PTSD; DSM-IV and ICD-10). More patients with BMI >17.5 kg/m(2) had lifetime and recent mood (affective) disorders and lifetime PTSD (DSM-IV and ICD-10). The results for 'excessive exercisers' varied and appeared inconsistent. There were no differences in any disorders for objective binge eaters. DISCUSSION Patients who induce vomiting have more psychiatric comorbidity than 'non-vomiters', both lifetime and recent, and may benefit from diagnostic recognition as a separate group, for example 'vomiting' or 'purging' ED, who can then receive specialist treatment for their comorbidity and associated problems.

Abstract
As a prerequisite for area-wide application of the sterile insect technique in an area encompassing northern Argentina and southern Brazil, prezygotic and postzygotic reproductive compatibility among three geographically distant populations in the area was tested. In field cages, sexually mature adults of each population were found to be sexually compatible, mating duration was not affected by fly origin and there was no clear evidence of spatial partition of mating location. In the laboratory, homotypic and heterotypic crosses for all possible combinations displayed similar levels of fertility and yielded F1 adults without distortion of the sex ratio. Finally, F1 hybrid and parental adults produced equally viable F2 eggs. Put together, our results and those from earlier studies suggest that a large area, ranging from Buenos Aires to the surroundings of São Paulo, could be managed using a single A. fraterculus mass-reared strain. At the northern margin of this area, two A. fraterculus morphotypes appear to coexist in sympatry. We delineate future research to further delimit the distribution of the aff1 morphotype (Argentina-southern Brazil) and to gain insight into evolutionary patterns producing divergence and radiation of tropical fruit fly species.

Abstract
RNA interference can be mediated by fully complementary siRNA or partially complementary miRNA. siRNAs are widely used to suppress viral replication and the fully complementary siRNA bound Ago-2 in the RISC is known to degrade the target RNA. Although other argonaute proteins lacking slicer activity can also bind oligonucleotides with both si and miRNA structures, whether they can also contribute to antiviral effects is not entirely clear. We tested si and miRNA structured oligos for target repression in dual luciferase assays as well as for inhibition of Dengue and West Nile virus replication in ES cells expressing individual Ago proteins. In luciferase assays, both fully complementary and partially complementary oligos effectively repressed their targets in all individual Ago expressing cell lines, although the efficacy with fully complementary oligos was higher in Ago-2+ cells. However, partially complementary oligos had no effect on virus replication in any cell line, while fully complementary siRNAs were highly effective in Ago-2 expressing, but not in cells expressing other Ago proteins. This occurred irrespective of whether the target sequences were located in the coding region or 3'UTR of the virus. We conclude that Ago-2 slicer activity is essential for anti-viral efficacy of siRNAs and miRNA-mediated translational repression/transcript destabilization is too weak to suppress the abundantly expressed flaviviral proteins.

Abstract
BACKGROUND Autologous Natural Killer (NK) cells and Cytotoxic T Lymphocytes (CTLs) based immune-cell therapy, otherwise called as Autologous Immune enhancement therapy (AIET), though has been in clinical practice in several developed nations since early 90s, in India it is in infancy due to lack of technological knowhow. Our institute has been providing the AIET cell expansion services since 2005 and we here in report our experience in 30 such patients of both solid tumours and hematological malignancies. MATERIALS & METHODS The number of AIET transfusions in each patient ranged from one to six. All the patients included had Stage III to IV malignancy. AIET was either given along with the chemotherapy or after the completion of a minimum of six cycles of chemotherapy in all the patients. 70 ml of Peripheral Blood was collected each time. The protocol followed was as per Terunuma et al (Breast Cancer 2010) which uses only the patients' autologous plasma for expansion of the Natural Killer Cells and Cytotoxic T lymphocytes from the peripheral blood. The cells were cultured for a period of 10 to 16 days and then transfused to the patients intravenously. The cells were subjected to Flow cytometry before and after the in vitro expansion. Feeder layers were not used in the procedure of in vitro expansion at any stage. RESULTS The percentage of NK cells and CTLs after expansion by flow cytometry ranged from 60 to 82 %. There were no adverse reactions in any of the patients following transfusion. The mean prolonged survival time was 15 months and 27% of the patients had Static non-progressive disease after the therapy. Two patients reported significant decrease in Cancer marker levels after AIET and among the terminally ill, two had more than two years survival. All the patients reported improvement in quality of life and resumption of appetite following AIET. CONCLUSION Optimal in vitro expansion of NK cells and CTLs of patients with stage III-IV cancer either concurrently or after chemotherapy could be accomplished using autologous serum without use of feeder layers. The In vitro expanded NK cells and CTLs when given intravenously decrease the tumor size and prolong the survival without any adverse effect in our experience.

Abstract
BACKGROUND Numerous Clinical studies have reported the safety and efficacy of injection of one Marrow and Peripheral Blood Mononuclear cells in patients with lower limb ischemia. Earlier we have reported the six months follow-up of successful application of autologous bone marrow mononuclear cells in patients with Fontaine Stage IV critical limb ischemia due to diabetes. As a continuation of the previous study, herein we report the long term results of the six patients after a follow-up for five years. MATERIALS & METHODS Six Diabetic patients with Fontaine Stage IV critical limb ischemia with ulcers were given intra-lesional injections of their autologous bone marrow mononuclear cells (BMMNC), isolated following the cGMP protocols. The patients have been followed up at regular intervals for five years after the treatment with all relevant clinical investigations. RESULTS Six months follow-up results revealed that all the patients showed improvements with appearance of healthy granulation tissue and uniform revascularization. Complete healing was reported at a mean duration of nine months in five patients and one patient died due to a complication of renal failure, peritoneal dialysis and cardiac failure, which were unrelated to the BMMNC injection. Five year continuous follow-up revealed that the healed tissue with or without skin grafting remained healthy in all the five patients and two of the patients are able to walk without support with a pain free walking distance of greater than 100m.There were no adverse effects in any of the patients.. CONCLUSION Autologous bone marrow stem cell therapy has been found to be salvaging the affected limb in patients with Fontaine Stage IV Critical Limb ischemia patients where revascularization was not feasible. Hence with our experience of six patients we recommend that the same should be considered in patients of similar clinical parameters before considering an amputation.

Abstract
INTRODUCTION The cartilage injuries demand novel therapeutic approaches as the success rates of the current conventional strategies for the repair of injured articular cartilages are not that encouraging. Earlier we have reported that the Thermoreversible Gelation Polymer (TGP) is an ideal scaffold for human chondrocyte expansion in vitro. In this study, we report the preliminary results of the in vitro expansion, characterization and experimental in vivo transplantation of chondrocytes in a rabbit model of cartilage injury. MATERIALS & METHODS Nine rabbits were included in this study scheduled for two years, after approval by the ethics committee. In the first animal, Chondrocytes were isolated from the weight bearing area of patellar groove in the left hindlimb and cultured in TGP Scaffold and maintained at 37°C in 5% carbon dioxide incubator for 64 days without growth factors. Then the TGP-Chondrocyte construct was transplanted into an experimental defect created in the knee of the right forelimb of the same rabbit. After a period of 10 weeks, a biopsy was taken from the transplanted region and subjected to morphological analysis, characterization by histopathology (H&E stain) and Immunohistochemistry (S-100 staining). RESULTS The chondrocytes in the 3D TGP culture had round to oval shaped morphology without any de-differentiation which is otherwise observed in Conventional 2D cultures. A macroscopic structure which resembled cartilage was appreciated in the TGP construct in vitro after 64 days which was then transplanted to the rabbit. The H&E and Immunohistochemistry studies confirmed the presence of chondrocytes in the biopsy tissue. CONCLUSION Based on the results, we conclude that the TGP significantly supports the in vitro expansion of chondrocytes for a longer period and the 3D culture using TGP preserves the phenotype of the articular chondrocytes. The tissue thus grown when implanted with the TGP has engrafted well without any adverse reactions and upon confirmation of safety following completion of the entire study with adequate follow-up, human applications could be considered.

Abstract
BACKGROUND Though the transplantation of in vitro expanded human corneal endothelial precursors in animal models of endothelial damage by injecting into the anterior chamber has been reported, the practical difficulties of accomplishing such procedure in human patients have been a hurdle to clinical translation. Here we report the successful transplantation of in vitro expanded human corneal precursor cells to an animal eye using a transparent Nano-composite sheet and their engraftment. MATERIALS & METHODS Human Corneal endothelial cells (HCEC) were isolated from human cadaver eyes with informed consent and expanded in the lab using a sphere forming assay in a novel Thermoreversible Gelation Polymer (TGP) for 26 days. HCEC obtained by sphere forming assay were seeded in a novel Nano-composite sheet, which was made of PNIPA-NC gels by in-situ, free-radical polymerization of NIPA monomer in the presence of exfoliated clay (synthetic hectorite "Laponite XLG") uniformly dispersed in aqueous media. After a further seven days in vitro culture of HCEC in the Nano-composite sheet, cells were harvested and transplanted on cadaver-bovine eyes (n=3). The cells were injected between the corneal endothelial layer and the Nano-composite sheet that had been placed prior to the injection in close proximity to the endothelial layer. After three hours, the transplanted Nano-composite sheets were removed from the bovine eyes and subjected to microscopic examination. The corneas were subjected to Histo-pathological studies along with controls. RESULTS HCEC formed sphere like colonies in TGP which expressed relevant markers as confirmed by RT-PCR. Microscopic studies of the Nanosheets and histopathological studies of the cornea of the Bull's eye revealed that the HCEC got engrafted to the corneal endothelial layer of the bovine eyes with no remnant cells in the Nanosheet. CONCLUSION Transplantation of in vitro expanded donor human corneal endothelial cells using a transparent Nano-composite sheet was feasible in bovine eyes and the HCEC an engrafted within three hours of transplantation. Pilot human studies could be planned for utilization of this material and strategy.

Abstract
BACKGROUND Autologous Bone Marrow stem Cell transplantation is a viable therapeutic option for patients with end stage heart failure due to cardiomyopathy of varied etiology as there are only limited treatment options other than cardiac transplantation. The rationale behind the application of stem cells in these patients include Stem cells directly replace the affected cells by differentiation into the damaged cell typeStem cells also exert Paracrine effects by secretion of growth factors (VGEF,FGF-1)to stimulate local cell growthIn addition to the above, stem cells release signaling factors which recruit stem cells from elsewhere by modulating the immune system. MATERIALS & METHODS In this presentation we describe our study on a series of 13 patients who received isolated and expanded CD 34 cells from the bone marrow. Seven had ischemic dysfunction, three had dilated cardiomyopathy and three had primary pulmonary hypertension. Five patients received the stem cells via intracoronary injection, three directly into the myocardium and three intrapulmonary. RESULTS All patients showed functional improvement of the myocardium recorded by non-invasive investigations and improvement in the quality of life. Follow up period ranged from 6 months to 2 years. CONCLUSION Our experience with bone marrow derived stem cells in patients with cardiomyopathy has been encouraging. More studies are planned in the future.

Abstract
Background Ceftriaxone is commonly used as an alternative antibiotic drug in treating syphilis but clinical data on its efficacy are limited. Objective: To evaluate the response of HIV-infected patients with active syphilis to treatment with penicillin or ceftriaxone. Methods A retrospective study involving 24 consecutive patients with a positive Veneral Disease Research Laboratory test (VDRL) and at least one specific treponemal test. 12 patients were treated with different regimens of high-dose penicillin G for at least 2 weeks. Another 12 patients were treated with ceftriaxone 1-2 g per day intravenously for 10-21 days. Results After a median follow up of 18,3 months all patients of the penicillin-treated group and 11 of 12 ceftriaxone-treated patients showed a ≥ 4-fold decline in VDRL-titers; 91% of them already within 6 months after therapy. Conclusion Our serological data demonstrate a comparable efficacy of currently recommened penicillin and ceftriaxone treatment regimens for active syphilis in HIV-infected patients.

Abstract
OBJECTIVE To study the relationship of adolescent development and eating disorder related quality of life in Indian females. METHOD 461 female school students (aged 12-17 yrs) were recruited from middle to high socio-economic status (SES), English speaking schools in Delhi, India. Adolescent development was measured by Tanner stage and months since menarche. Subjects completed the Quality of Life for Eating Disorders questionnaire (QOL ED), which included six subscores. Correlation and partial correlation coefficient analysis to control for Body Mass Index (BMI) were performed. RESULTS After controlling for BMI, all adolescent development measures were correlated with the psychological feelings (PSY) subscore. This subscore contained items relating to confusion, social unease, sadness, difficulty coping, desiring perfection and loss of control. Tanner breast stage was correlated with the eating behaviour (EB) subscore. DISCUSSION During adolescent development, Indian girls became more aware of their psychological feelings and emotions. Only those reporting breast development were using behaviours to control their body, weight and shape. These behaviours are not associated with the presence of disordered eating thoughts, such as preoccupation with food, eating, body weight or shape.

Abstract
Chhattisgarh state is still endemic for leprosy and has a large tribal population. During 2003-2009, a total of 1530 untreated leprosy cases reported to the Leprosy Mission Referral Hospital in Champa, of which 151(9%) were classified as belonging to the scheduled tribes. The characteristics of these new tribal patients are described and compared with other patients and to the demographics of the tribals in the general population of the State. While tribals were accessing the leprosy services similar to the other social groups, the delay in reporting, high BI and other features pose more serious problems in the transmission of leprosy and in management of complications due to the harsh environment and occupational patterns of the tribals. Appropriate strategies and more community based approaches will be necessary if these groups are also targeted for eradication of leprosy.

Abstract
Lactococcus lactis can decrease the redox potential at pH 7 (E(h7)) from 200 to -200 mV in oxygen free Man-Rogosa-Sharpe media. Neither the consumption of oxidizing compounds or the release of reducing compounds during lactic acid fermentation were involved in the decrease in E(h7) by the bacteria. Thiol groups located on the bacterial cell surface appear to be the main components that are able to establish a greater exchange current between the Pt electrode and the bacteria. After the final E(h7) (-200 mV) was reached, only thiol-reactive reagents could restore the initial E(h7) value. Inhibition of the proton motive force showed no effect on maintaining the final E(h7) value. These results suggest that maintaining the exofacial thiol (-SH) groups in a reduced state does not depend on an active mechanism. Thiol groups appear to be displayed by membrane proteins or cell wall-bound proteins and may participate in protecting cells against oxidative stress.

Abstract
A 19-year-old Indian man presented with a history of proximal muscle weakness, knock knees and gynaecomastia. On examination he had features of rickets and bilateral small testes. Karyotyping revealed a chromosomal pattern of 47,XXX, confirming the diagnosis of Klinefelter's syndrome. He was also found to have hyperchloraemic metabolic acidosis with hypokalaemia, hypophosphataemia, phosphaturia and glycosuria, which favoured a diagnosis of proximal renal tubular acidosis. Patients with Klinefelter's syndrome typically have a tall stature due to androgen deficiency, resulting in unfused epiphyses and an additional X chromosome. However, this patient had a short stature due to associated proximal renal tubular acidosis. To the best of our knowledge, this is the second case of Klinefelter's syndrome with short stature due to associated renal tubular acidosis reported in the literature. This report highlights the need to consider other causes when patients with Klinefelter's syndrome present with a short stature.

Abstract
Oxidative stress is detrimental to fertility potential. Retinol and alpha-tocopherol are natural antioxidants that inhibit lipid peroxidation and protect against cell damage induced by oxidative stress. This study evaluated whether gender-related differences in antioxidant status exist among couples with infertility and, if so, to evaluate relevant factors that may contribute to such differences. Retinol and alpha-tocopherol in the sera of 40 couples and in the semen of 40 men were measured using high performance liquid chromatography. Serum retinol and alpha-tocopherol in women were significantly higher than in men (both P < 0.001). There was an inverse relationship between body mass index and serum retinol and alpha-tocopherol in both men and women. Heavy smokers (>or=20 cigarettes/day), compared with nonsmokers, had lower serum concentrations of retinol and alpha-tocopherol. Serum concentrations of retinol and alpha-tocopherol in men with normal sperm parameters were significantly higher than in those with oligozoospermia and asthenozoospermia (both P < 0.001). Lower serum retinol and alpha-tocopherol in men compared with their female partners could be related to their older age, higher body mass index and smoking habits. Low concentrations of these natural antioxidants were associated with abnormal semen parameters in men and anovulation in women.

Abstract
Monitoring childhood leprosy in terms of incidence and occurrence of deformities are crucial for better control and understanding the transmission of the disease. In this paper, a profile of all new untreated leprosy patients below 15 years of age who reported at a Leprosy Referral Centre in West Bengal during 2004-2006 are described. Of 151 children studied, 84 (55.6%) were males, 33% were multibacillary and of them, 30% were smear positive. 16% had already developed grade 2 disability (WHO). Multiple nerve involvement was seen in a quarter of children. These findings highlight the seriousness of leprosy among children and the great need to address these issues urgently. Awareness, active case detection especially among contacts and motivation are the essential needs of the hour to prevent tragedy of deformed children due to a totally manageable disease.

Abstract
Mycobacterium leprae strains from Indian leprosy patients were analyzed using the six base tandem repeat, GACATC, in rpoT gene as genetic marker. DNA was extracted from slit-skin smears and nasal swabs of new untreated as well as treated leprosy patients living in different regions of India. PCR amplification of rpoT gene and sequencing of amplicons showed the presence of two genotype of M. leprae in this study, 73.4% having three copies (ancient Indian type) and 26.6% contain 4 copies (considered to be Japanese and Korean). These genotypes along with other short tandem repeats may help in studying the historical spread of disease and the strains of M. leprae disseminated by various human races that migrated to India from other places of Asia and European countries during our history.

Abstract
Steroids, while still the most powerful drugs to manage leprosy reactions, predispose some patients to other morbidities such as diabetes, glaucoma, hypertension etc. A prospective cohort study was done in Kolkata, India among leprosy patients in reaction to determine the extent of steroid induced diabetes mellitus (SID). All leprosy patients with type 1 or type 2 reactions or neuritis admitted in 2006 to the Leprosy Mission Hospital in Kolkata, who had no past or current history and whose blood sugars on fasting were <126 mg/dl or postprandial <200 mg/dl were monitored fortnightly while on steroid therapy, estimating blood glucose by a glucometer using standard strips. Of 81 patients, 19 (23.5%) manifested steroid-induced diabetes mellitus. Compared to those who didn't, there were significantly more LL/BL patients with positive BI among SID whose cumulative prednisolone dosage was nearly 9000 mg as compared to half the amount among others. Steroid induced diabetes is a serious complication among leprosy patients treated with prednisolone for reactions requiring careful monitoring for detection and appropriate clinical management.

Abstract
Desmoid tumour of the breast is a rare fibroblastic tumour whose spectrum ranges from being locally inert to aggressive and destructive, and represents 0.2% of all breast tumours. A 22-year-old woman, 2 years post-cosmetic augmentation mammoplasty with silicone implants, presented with a 6-month history of an enlarging mass in her left breast. Ultrasound showed a well-defined, hypoechoic mass arising within the muscles of the anterior chest, deep beneath the implant and not involving the underlying rib. Fine needle aspiration (FNA) showed features in keeping with changes associated with silicone implants. A provisional diagnosis of scarring and fibroblastic proliferation was made. The lesion was excised and the implant, noted to be intact, was exchanged. Immunochemistry showed strong positivity for vimentin and variable positivity for SMA and desmin, and patchy positivity for beta catenin. A final diagnosis of aggressive fibromatosis was made. Although the association of desmoid tumour and breast implants has been described, this case is unique as the FNA was highly suggestive of a silicone granuloma and the diagnosis of desmoid tumour was made on definitive pathology. The aetiology of desmoid tumours is reviewed and current treatment modalities discussed.
