    Background: Oral cancer is thought to be the sixth most common form of cancer causing upto 50% of all malignancies in parts of India and South-East Asia, and an increasing trend in oral cancer mortality have been observed in several countries. The aim of the study was to evaluate the etiological factors contributing to oral and oropharyngeal carcinomas and its association with histopathological findings.Methods: This one year duration study was carried out on 100 patients diagnosed as oral and oropharyngeal cancer attending the Department of Otorhinolaryngology and Head and Neck Surgery, Gajra Raja Medical College and J.A. Group of Hospitals, Gwalior, Madhya Pradesh, India.Results: 98% of the patients were histologically squamous cell carcinomas, with well differentiated carcinoma being the most common i.e. 59%. The etiological factors which were found to have statistically significant association in oral cancers were poor oral hygiene, tobacco chewing and pan chewing. Other factors like cigarette/bidi smoking, alcoholism were also common.Conclusions: Any irritation or ulceration in the mouth not attributed to a recognizable causal factor and not healing within four weeks, especially in presence of risk factors must be investigated for its malignant potential. There is a need for improvement in early detection of oral and oropharyngeal carcinomas, because in the initial stages, treatment is more effective and the morbidity is minimal. Keywords:

    Background: Menstruation and related problems are difficult issues for adolescent girls and are a common reason for consulting healthcare providers.Objectives: To study age at menarche and menstrual problems among school girls in Lucknow district of north India.Materials and Methods: A cross‑sectional study was carried out in urban as well as rural schools of Lucknow district from October 2008 to September 2009. Multistage random sampling was used to select the requisite number of girls. A total of 847 school‑going adolescent girls between 10 and 19 years of age were interviewed and examined. Statistical analyses were done using percentage and Chi‑square test. Results: Out of 847 adolescent girls, 76.7% (650) girls had attained menarche. The overall mean age at menarche was 12.84 (1.4) years. The age at menarche and duration of menstrual flow were significantly associated with place of schools. About one‑fourth of the girls in all the three age groups (10‑13, 14‑16 and 17‑19 years) had irregular menstrual cycle. Overall, 73.7% (479/650) girls had dysmenorrhea, with 74.3% (323/435) girls in urban schools and 72.6% (156/215) girls in rural schools. There was no significant association between reproductive tract illnesses and place of schools.Conclusion: Menstruation is an important milestone for adolescent girls and menstrual problems are common among adolescent girls. So, there is a need to explain everything correctly about menstruation. It was suggested that a strong need exists for strong health educational activities among the adolescent girls, their parents, and teachers for effective management of menstrual problems among all adolescent girls. Keywords: Adolescent girls, dysmenorrhea, Lucknow district, menstruatio

    Specificity and ligand affinities of the cocaine aptamer: impact of structural features and physiological NaCl

    Get PDF
    The cocaine aptamer has been seen as a good candidate for development as a probe for cocaine in many contexts. Here, we demonstrate that the aptamer binds cocaine, norcocaine, and cocaethylene with similar affinities and aminoglycosides with similar or higher affinities in a mutually exclusive manner with cocaine. Analysis of its affinities for a series of cocaine derivatives shows that the aptamer specificity is the consequence of its interaction with all faces of the cocaine molecule. Circular dichroism spectroscopy and 2-aminopurine (2AP) fluorescence studies show no evidence of large structural rearrangement of the cocaine aptamer upon ligand binding, which is contrary to the general view of this aptamer. The aptamer’s affinity for cocaine and neomycin-B decreases with the inclusion of physiological NaCl. The substitution of 2AP for A in position 6 (2AP6) of the aptamer sequence eliminated the effect of NaCl on its affinities for cocaine and analogues, but not for neomycin-B, showing a selective effect of 2AP substitution on cocaine binding. The affinity for cocaine also decreased with increasing concentrations of serum or urine, with the 2AP6 substitution blunting the effect of urine. Its low affinities for cocaine and metabolites and its ability to bind irrelevant compounds limit the opportunities for application of this aptamer in its current form as a selective and reliable sensor for cocaine. However, these studies also show that a small structural adjustment to the aptamer (2AP exchanged for adenine) can increase its specificity for cocaine in physiological NaCl relative to an off-target ligand

    The work investigated the design and evaluation of microspheres of Nitazoxanide by Ionotropic gelation technique met. 32 Factorial designs were used and concentration of polymer carbopol-934 (X1) and Ethyl cellulose (X2) were selected as the independent variables. The surface morphology study by SEM indicated that microspheres were spherical with smooth surface. There was no interaction between the drug and polymers, as studied by FTIR study. The prepared microspheres were characterized by entrapment efficiency, particle size micromeritic properties. It was observed that on increasing polymer concentration of formulations, % yield, the entrapment efficiency and particle size were increased whereas % drug release decreased. The In Vitro release study was done using U.S.P. dissolution rate basket type apparatus in phosphate buffer pH 7.4 for 10 hr. It shows that on increasing polymer concentration the drug release of all formulations was gradually decreased. In Vitro mucoadhesion study depicts that as the polymer concentration increased, mucoadhesive nature of the formulation was also increased. The microspheres of NTZ (formulation F9) showed best results due to highest drug entrapment efficiency (85.50%), and percentage drug release after 10.0 hr. was 50.25%. The rate of release followed First order kinetics. The microspheres exhibits good mucoadhesive properties in  in- vitro wash-off test at pH 7.4 (Intestinal pH) than pH 1.2 (gastric pH),because the drug was completely absorbed in Gastrointestinal tract, Therefore, it can be concluded that Nitazoxanide Loaded algino-carbopol-934 microspheres can be formulated for sustained drug delivery of Nitazoxanide used in Chronic Hipatitis-C. Keywords: Mucoadhesive microspheres, Nitazoxanide, Carbopol-934, Ethyl cellulose, Sodium Alginate, Factorial design
