Extensive vibrational investigations of 1,5-Dichloro-2,3-dinitrobenzene (DCDNB) have been carried out with FT-IR and FTRaman techniques. The electronic structure of the molecule has been analysed by UV-Visible and NMR spectroscopies. This studies were carried out with Hartree-Fock (HF) method utilizing 6-311+G(d,p) and 6-311++G(d,p) basis sets to determine the structural, vibrational and electr...

Phellandrenes are naturally occurring cyclic dienes belonging to monoterpene class and have many medicinal applications. In the present study, some resonance stabilized radicals from α- β-phellandrene also closed shell structures those been investigated within constraints of density functional theory basis set employed. For structure optimizations closed-shell open-shell structures, B3LYP/6-311...

OBJECTIVES/HYPOTHESIS Nasolabial cysts are rare nonodontogenic cysts arising commonly in the nasal alar region. Intraoral sublabial resection of nasolabial cysts is considered the standard treatment modality. In the past 16 years, transnasal endoscopic marsupialization has emerged as an alternative approach for these lesions. A systematic review on this entity was performed to evaluate manageme...

Site U1328 (Scientific Prospectus Site CAS-06A) is located within a seafloor cold-vent field, with dimensions 2 km by 4 km, consisting of at least four vents associated with nearsurface faults. The cold vents are characterized by near-vertical seismic blank (or wipe-out) zones that are between 80 and several 100 m wide, and show a clear E-W trend as identified from 3D seismic imaging. The most ...

The choice of tactics for managing a patient with mycosis fungoides is determined by the stage disease. In early stages fungoides, treatment approach using external therapy and various ultraviolet irradiation spectra (UVB-311 nm PUVA therapy) preferable. With insufficient efficiency / or short remissions in some patients, it possible to use combined methods stages: UVB-311 therapy. combination ...

PURPOSE To evaluate clinical features and risks for transformation of conjunctival primary acquired melanosis (PAM) into melanoma. METHODS Retrospective chart review and Kaplan-Meier estimates of times to PAM enlargement, recurrence, and transformation into melanoma. MAIN OUTCOME MEASURES PAM enlargement, recurrence, and transformation into melanoma. RESULTS The mean patient age at diagno...
