Background: The coronoid process of mandible is thin flat triangular process from the ramus of the mandible. This varies in the shapes and size. It gives attachment to two main muscles that is temporalis and masseter muscle. The coronoid process is the favourable donor site. A Coronoid process graft can be used for alveolar defects repair, orbital floor repair, maxillary augmentation, repair of non-union fracture of mandible. These grafts can be widely used in the reconstruction of osseous defects in oral and maxilla-facial region. Aim of the Study: This study is done to find out the variation in shape of coronoid process of mandible, Intercoronoid distance, coronoid- condylar distance and the length and breadth and thickness of the coronoid process of mandible. Methods: The study was done on the 100 dry human mandibles from the osteology bank of Saveetha medical college and hospital. The distance was measured using the digital vernier callipers and the values were analysed. Results: This study is useful for the maxillofacial surgeon and this useful...

Periodontal dressings were widely used after flap surgery to protect the surgical site since long. This study compared polyether urethane dimethacrylate resin based Barricaid dressing and non-eugenol based periodontal dressings in the perspective of pain, esthetics and patient acceptance using a randomized split-mouth study design. Fifteen patients coming to the Department of Periodontics at ITS Dental College and diagnosed as a case of generalized chronic periodontitis were selected. Total 30sites (2 sites in each patient) requiring the flap surgery were selected and contralateral sites in each patient were randomly allocated into two groups. At baseline plaque index, Modified gingival index were recorded. In group-1 non-eugenol dressing and in group-II light cured periodontal dressing were applied to secure the surgical sites after flap surgery. At day1,2 and 3 pain and discomort was assessed using Numeric Pain Rating Scale.(NPRS) After 7 days patients were recalled for removal of dressing, recording the indices and asked to fill a questionarrie regarding the patient acceptability. Collected data were subjected to statistical analysis and non-significant...

Objective: Enhancement of oral bioavailability of poorly water soluble drugs is the most challenging aspects of drug development. It is very important to find appropriate formulation approaches to improve the aqueous solubility and bioavailability of poorly aqueous soluble drugs. Ezetimibe is a new lipid lowering agent in the management of hyper-cholesterolemia. The drug is water-insoluble, lipophilic, and highly permeable. Therefore, bioavailability of ezetimibe may be improved by increasing its solubility. Method: The aim of the present study was to improve the solubility and dissolution rate of Ezetimibe by preparing microspheres by spray drying technique using HP β-cyclodextrin. Ezetimibe microspheres containing different ratios of HP- β-cyclodextrin were produced by using Propanol and water (50:50) as a solvent system. The prepared formulations containing different ratios of Ezetimibe and HP β-cyclodextrinwere evaluated for solubility and in-vitro dissolution. The prepared formulations were characterized by differential scanning calorimetry (DSC), X-ray diffraction spectroscopy (XRD), fourier transform infra-red spectroscopy (FTIR) and scanning electron microscopy (SEM). Dissolution profile of the prepared spray dried microspheres was compared with...

Synthesis of new organometallic Schiff bases complexes with general formula [ML)xH2O] [where M = Mn(II), Ni(II), Cu(II) Pd(II) and Pt(II), L=2,2′-{(1R,1′S)-1,1’Ferrocen-2,4-dien-1-yl-2,2′-diyl bis [(Z)methyl-ylidenenitrilo]}bis(3-iodophenol)] have been prepared and characterized by elemental analysis, magnetic susceptibility, Conductivity IR, UV-Visible, Mass spectra and TGA/DTA. Organometallic Schiff base is tetradentate and co-ordination through nitrogen of azomethine (>C=N-) and oxygen of Hydroxyl group. The complexes have octahedral geometry with six coordination number. Electronic spectra of the complexes were recorded and its parameters like Nephelauxetic effect (β), bonding parameter (b1/2) and Sinha’s parameter (δ %) are calculated. TGA and DTA results of [Pt (C24H16 FeI2N2O2).2H2O] and [Pd (C24H16 FeI2N2O2).2H2O] are reported, Complexes were losing weight due to exothermic and endothermic process. The mass spectra of prepared ligand (C24H18 FeI2 N2O2) and its complex such as [Mn (C24H16FeI2N2O2).2H2O] were used to compare their stoichiometric composition and it found that near about equal to the theoretical mass of the complex and prepared ligand. Synthesis of nanoparticles of OMNPs (organometallic Nanoparticles) of Cu(II) Complex with SEM and EDX were...

Hypothyroidism is a common disorder of endocrine system in which the thyroid gland does not produce enough thyroid hormone. The most common cause of hypothyroidism is inflammation of the thyroid gland, which damages the gland’s cells. It can affect growth, cellular processes and many other body functions. As more damage accumulates, the risk of Hypothyroidism increases. In order to make an impact on Hypothyroidism, we must understand the molecular processes and structure-function relationships of TSH permitted better understanding of the role of specific protein and carbohydrate domains in the synthesis, bioactivity, and clearance of this hormone. Thyroid hormone receptor alfa-1 (THRA1) is an endocrine nuclear receptor that mediates the transcriptional effects of thyroid hormone (triiodothyronine, T3). It acts as an agonist i.e. it stimulates the production of thyroid hormone by triggering a response in the cell, which is selected as target protein. The primary goal of the project was to unearth natural chemical compounds that can be used as an agonist (increase thyroid hormone level in patients) for the...
