Chronic Protracted Dislocation of Temporomandibular Joint in a Trauma Patient - A Case Report.

Rationale: Chronic protracted temporomandibular joint (TMJ) dislocation refers to a condition that persists for more than one month without reduction.

Patient Concerns: A 47-year-old male patient first presented to the Department of Maxillofacial Surgery complaining of the inability to close his mouth for nine months.

Diagnosis: Chronic protracted dislocation of the temporomandibular joint.

Assessment of epidermal growth factor receptor in histological, clinical and pathological staging of oral squamous cell carcinoma.

Background: Oral squamous cell carcinoma is an invasive epithelial neoplasm with varying degrees of squamous differentiation that arises from the following anatomic sites: the oral cavity, particularly oral soft tissues including the gingival and alveolar mucosa, floor of the mouth, tongue, soft and hard palate, tonsils and oropharynx. In normal epithelium EGFR is localized to basal cell layer, while its expression beyond basal localization in cancerous tissue suggest that correlation of EGFR and tumor progression might exist. The present study aimed to assess epidermal growth factor receptor in histological, clinical and pathological staging of oral squamous cell carcinoma.

Growth and characterization of novel organic 3-Hydroxy Benzaldehyde-N-methyl 4 Stilbazolium Tosylate crystals for NLO applications.

The 3-Hydroxy Benzaldehyde-N-methyl 4-Stilbazolium Tosylate (3- HBST) is a new organic NLO crystal and it is a new derivative in stilbazolium tosylate family. In this work we have synthesized 3-HBST and the single crystal was grown by conventional slow cooling method. The structure and lattice parameters of the grown crystal were determined by the single crystal X-ray diffraction (XRD) technique and it is exhibiting good crystalline nature which is observed from the powder XRD.

Crystal structure of 4-(di-methyl-amino)-pyridinium 4-amino-benzoate dihydrate.

In the title hydrated mol-ecular salt, C7H11N2 (+)·C7H6NO2 (-)·2H2O, the cation is protonated at the pyridine N atom and the dihedral angle between the benzene ring and the CO2 (-) group in the anion is 8.5 (2)°. In the crystal, the cation forms an N-H⋯O hydrogen bond to the anion and the anion forms two N-H⋯O hydrogen bonds to adjacent water mol-ecules.

Studies on the growth, spectral, structural, electrical, optical and mechanical properties of Uronium 3-carboxy-4-hydroxybenzenesulfonate single crystal for third-order nonlinear optical applications.

Organic Uronium 3-carboxy-4-hydroxybenzenesulfonate (UCHBS) nonlinear optical single crystal was grown by solution growth technique. The solubility and nucleation studies were performed for UCHBS at different temperatures 30, 35, 40, 45, 50 and 55°C. The crystal structure of UCHBS was elucidated from single crystal X-ray diffraction study.
