Study of Pap smear and other feasible tests among self reported symptomatic married women in reproductive age group (15-49 yrs) regarding reproductive tract infections in a rural community of Maharashtra
Background: Reproductive tract infections (RTIs) represent a major public health problem in developing countries. Integrating RTIs/STIs management and early detection of cervical dysplasia in broader reproductive health services can improve women’s health. The objectives of the study were 1. To study the association of socio-demographic & reproductive factors among self-reported symptomatic women for reproductive tract infections. 2. To carry out clinical examination & feasible tests like PH, gram staining, VDRL for reproductive tract infections. 3. To study Pap smear among study subjects.Methods: A cross sectional study community based study was carried out in villages under ‘Parol’ Primary Health Centre of Thane district, Maharashtra, India. A total of 415 married women in reproductive age group were interviewed and examined. Pre-structured, pre-designed questionnaire was used. Clinical examination & feasible laboratory tests were done. Results were analyzed with the help of Microsoft Excel & SPSS 15. Results: A total of 415 women were interviewed, of them 263(63.4%) had one or more symptoms of reproductive tract infections. On examination, 69(35%) had cervicitis and 30(15.2%) pelvic inflammatory disease, 39(19.8%) bacterial vaginosis and candidiasis in 61(31%). Cervical erosion was present in 147(74.6%) women. On Pap smear, 20(10.2%) women had ASCUS (Atypical squamous cells of undetermined significance). Only 2(1%) women found HIV positive. No woman was found VDRL reactive.Conclusion: Routine RTI/STI screening and periodic surveys to detect the infection patterns which will helps to control HIV infections in the community is needed in the remote tribal area as the current study shows high prevalence of reproductive tract infection.
Crystallization and Preliminary X-ray Studies of the Basic Lectin from Winged Bean (Psophocarpus tetragonolobus)
The basic lectin from winged bean (Psophocarpus tetragonolobus) could be crystallized using polyethyleneglycol (PEG) 4000 (I), PEG 8000 (II) and 2-methylpentane-2,4-diol (MPD) (III) as precipitants. Crystal forms I and II grew in the presence of methyl-α-Image -galactopyranoside or N -acetylgalactosamine while III grew in the absence of sugar. The three forms have the same space group (P21212) and similar unit cell dimensions with two dimeric molecules in the asymmetric unit. The unit cell dimensions are a = 156·8 Å, b = 89·0 Å, c = 73·3 Å for I, a = 155·5 Å, b = 92·3 Å, c = 72·5 Å for II and a = 148·3 Å, b = 90·7 Å, c = 73·8 Å for III. The crystals, particularly those grown using PEG 8000, are suitable for high resolution X-ray analysis, which is in progress
Electrical spin injection using GaCrN in a GaN based spin light emitting diode
We have demonstrated electrical spin-injection from GaCrN dilute magnetic semiconductor (DMS) in a GaN-based spin light emitting diode (spin-LED). The remanent in-plane magnetization of the thin-film semiconducting ferromagnet has been used for introducing the spin polarized electrons into the non-magnetic InGaN quantum well. The output circular polarization obtained from the spin-LED closely follows the normalized in-plane magnetization curve of the DMS. A saturation circular polarization of similar to 2.5% is obtained at 200 K. (C) 2013 AIP Publishing LLC

Targeting the NRF2/HO-1 Antioxidant Pathway in FLT3-ITD-Positive AML Enhances Therapy Efficacy
Acute myeloid leukemia (AML) is a molecularly heterogenous hematological malignancy, with one of the most common mutations being internal tandem duplication (ITD) of the juxtamembrane domain of the fms-like tyrosine kinase receptor-3 (FLT3). Despite the development of FLT3-directed tyrosine kinase inhibitors (TKI), relapse and resistance are problematic, requiring improved strategies. In both patient samples and cell lines, FLT3-ITD raises levels of reactive oxygen species (ROS) and elicits an antioxidant response which is linked to chemoresistance broadly in AML. NF-E2–related factor 2 (NRF2) is a transcription factor regulating the antioxidant response including heme oxygenase -1 (HO-1), a heat shock protein implicated in AML resistance. Here, we demonstrate that HO-1 is elevated in FLT3-ITD-bearing cells compared to FLT3-wild type (WT). Transient knockdown or inhibitor-based suppression of HO-1 enhances vulnerability to the TKI, quizartinib, in both TKI-resistant and sensitive primary AML and cell line models. NRF2 suppression (genetically or pharmacologically using brusatol) results in decreased HO-1, suggesting that TKI-resistance is dependent on an active NRF2-driven pathway. In AML-patient derived xenograft (PDX) models, brusatol, in combination with daunorubicin, reduces leukemia burden and prolongs survival. Cumulatively, these data encourage further development of brusatol and NRF2 inhibition as components of combination therapy for refractory AML

Treatment Delay in Oral and Oropharyngeal Cancer in Our Population: The Role of Socio-Economic Factors and Health-Seeking Behaviour
The objective is to assess the role of socio-economic factors and health-seeking behavior in treatment delay in oral and oropharyngeal cancer in our population. This article adapts—design: prospective study and setting: tertiary care centre. We studied 153 patients with oral and oropharyngeal squamous cell carcinoma who were managed in the department of otolaryngology and head and neck surgery between January 2006 and December 2007. There were 127 male patients (83%) and 26 females (17%) with ages ranging from 22 years to 70 years. Fifty-nine patients (39%) presented to us with early stage disease (i.e. stage I and II), whereas, 94 patients (61%) presented with late stage disease (i.e. stage III and IV). Of the 59 patients presenting with early stage disease, 20 were illiterate and 39 literate with 28 patients (47%) belonging to low socio-economic status and 32 patients (54%) having an access to primary health centre (PHC). Of the 94 patients presenting with late stage disease, 53 were illiterate and 41 literate with 58 patients (62%) belonging to low socio-economic status and 38 patients (40%) having an access to primary health centre. Literacy, socio-economic status, access to primary health centre and health-seeking behavior of our population has a significant association with the stage of presentation of patients with oral and oropharyngeal cancer
