This study deals with the generation and characterization of various solid-state forms of celecoxib, a selective cyclooxygenase-2 (COX-2) inhibitor. The drug was subjected to polymorphic screen using different solvents to explore the possibility of existence of different solid forms. N,N-Dimethyl acetamide (DMA) and N,N-dimethyl formamide (DMF) yielded solvates in 1:1 stoichiometric ratio. Quench cooling of the melt resulted in amorphous form of the drug. All these solid-state forms were characterized by thermoanalytical (DSC, TGA, HSM), crystallographic (XRD), microscopic (polarized, SEM), spectroscopic (FTIR), and elemental analysis techniques. Solubility and van't Hoff studies were carried out for their thermodynamic interpretation. Influence of morphology of different solid-state forms on flow behavior was also investigated. Molecular modeling studies were used to elucidate the interaction between solute and solvent molecules in the solvate. 相似文献

The practice of allopathic medicine by informal healthcare practitioners (IHPs) is ubiquitous in India. However, a little is known about the patients' experiences and IHPs' perspectives. The core questions guided the present study were (1) why do urban poor approach IHPs for healthcare? (2) what are their experiences of availing services from IHPs? and (3) what are the perspectives of IHPs about their practice with the population they serve? A qualitative research design guided the study. The study was conducted in the Gurugram city of Haryana, India. Nine IHPs and twenty‐seven patients who fit into the pre‐established inclusion criteria were interviewed. The findings of the study underline the structural constrains of healthcare access to the poor in India and the mutual dependencies between IHPs and the urban poor. Three themes were emerged corresponding to the perspectives of IHPs, and five themes were generated, which describes patients' experiences and perspectives of availing treatment. The factors that attract and sustain patients to IHPs are a mixture of socio‐economic aspects, which include poverty, inaccessibility, unaffordability, inefficient public healthcare facilities, and the positive behavioural and treatment attributes of the practitioners. The study implies urgent policy interventions to ensure quality healthcare to urban poor. 相似文献

Aim
To study associations of dermatoglyphic features with malocclusion in Indian children.Materials and methods
A total of 237 children aged 12–16 years, who attended our outpatient clinic in a government medical college, were selected. Finger and palm prints were collected, and fingertip pattern frequencies, total ridge counts (TRCs), and atd angles (formed by the triradii below the first and last digits and that in the hypothenar region of the palm) were calculated. These parameters were analyzed with their Angle’s class of malocclusion using appropriate statistical tests. Dermatoglyphic parameters were examined and asymmetry analysis was conducted in subjects with different occlusion patterns.Results
Although no fingerprint pattern was found to be specific for a particular class of occlusion, increased tendencies toward high frequencies of whorls in subjects with class II malocclusion and plain arches in those with class III malocclusion were observed. Significant differences in atd angle and TRC were observed among malocclusion types (p = 0.0001). Asymmetry scores did not differ significantly.Conclusion
Dermatoglyphic analysis can be used as an indicator of malocclusion at an early age, thereby aiding the development of treatments aiming to establish favorable occlusion. Inheritance and twin studies, as well as those conducted in different ethnic groups, are required to examine these relationships further. 相似文献10.
