Background: Dental anomalies might occur due to abnormal events during teeth development caused by environmental or genetic factors during histo differentiation or morph differentiation stages of embryological development. Aims of the study: To evaluate the distribution of developmental dental anomalies according to age and gender in relation to nutritional status in children attending College of Dentistry /University of Baghdad. Materials and method: After examination 5760 children aged 5-12 years of both genders only 147child with dental anomalies were found, all developmental dental anomalies that were clinically observable were recorded. The developmental dental anomalies which diagnosed in this study were supernumerary, missing teeth, talon cusp, microdontia, gemination, fusion, peg shape lateral, enamel hypoplasia, dentinogenesis imperfacta and amelodensis imperfacta. Nutritional status for each child assessed by measuring weight and height to calculate body mass index. Results: The results of the current study showed that the supernumerary teeth was the first most common anomaly seen in this study followed by localized hypoplasia which the second most common anomaly seen followed by missing teeth and microdontia respectively. Regarding total sample from 5 to 12 years old children, the findings showed that the children percent with number anomalies (42.9%) was highest than children percent with structural anomalies and shape anomalies (32.7%, and 24.5% respectively) with statistically highly significant difference (P<0.01). The shape anomalies and structural anomalies percent (25.0%, and 40.0% respectively) were higher among girls than boys while number anomalies percent (48.3%) was higher among boys than girls with non significant difference (P>0.05). The results showed that the underweight children showed higher percent (53.1%) among all age groups than children who were normal weight, over weight and obese (32.7%, 12.2%, and 2.0% respectively) with highly significant difference (P< 0.01). The results illustrated that both boys and girls showed highest percent of underweight (44.8%, and 65.0% respectively) followed by normal weight, over weight and obese with statistically non significant difference. The results also reported that the underweight children presented with highest shape and structural anomalies percent (75.0%, and 50.0% respectively) except number anomalies showed highest percent (47.6%) among normal weight children. Regarding total sample, the underweight children presented with highest dental anomalies percent of all anomalies types(53.1%)than normal weight, over weight and obese children with highly significant difference ( P< 0.01). Conclusion: The present study showed the association of nutritional status with dental anomalies among Iraqi children.
Compound 4-(((6-amino-7H-[1, 2, 4] triazolo [3, 4-b][1, 3, 4] thiadiazin-3-yl) methoxy) methyl)-2, 6-dimethoxyphenol (6) was synthesized by multi steps. The corresponding acetonitrile thioalkyl (7) was cyclized by refluxing with acetic acid to afford 4-(((6-amino-7H-[1, 2, 4] triazolo [3, 4-b][1, 3, 4] thiadiazin-3-yl) methoxy) methyl)-2, 6-dimethoxyphenol (8). Two new series of 4-(((6-(3-(4-aryl) thioureido)-7H-[1, 2, 4] triazolo [3, 4-b][1, 3, 4] thiadiazin-3-yl) methoxy) methyl)-2, 6-dimethoxyphenol (9a-c) and of 4-(((6-(substitutedbenzamido) 7H-[1, 2, 4] triazolo [3, 4-b][1, 3, 4] thiadiazin-3-yl) methoxy) methyl)-2, 6-dimethoxyphenol (10a-c) were synthesized as new derivatives for fused 1, 2, 4-trizaole-thiadiazine (8).

Two local fish Himri Carasobarbus luteus (Heckel, 1843) and Hishni Liza abu (Heckel, 1843) were stained with Alizarin Red and featured some anatomical qualities which cleared the difference of the muscular and skeletal fabric for each fish. Since clear Histologic differences appeared in these two species, it was intended from this study the possibility of adopting a diagnosis between local fish species by staining bones and tissues.
This work represents the preparation of the starting material, 3-chloro-2-oxo-1,4-dithiacyclohexane (S) using a new method. This material was reacted with, 4-phenylthiosemicarbazide to give (H3NS3) as a tetradentate ligand H3L. New complex of rhenium (V) with this ligand of the formula [ReO(L)] was prepared. New complexes of the general formula [M(HL)] of this ligand when reacted with some metal ions where: M = Ni(II), Cu(II), Cd(II), Zn(II), Hg(II) have been reported. The ligand and the complexes were characterized by infrared, ultraviolet–visible, mass, 1H nuclear magnetic resonance and atomic absorption spectroscopic techniques and by (HPLC), elemental analysis, and electrical conductivity. The proposed structure for H3L with Re (V) i

The complexes of the 2-hydroxy-4-Nitro phenyl piperonalidene with metal ions Cr(III), Ni(II), Pt(IV) and Zn(II) were prepared in ethanolic solution. These complexes were characterized by spectroscopic methods, conductivity, metal analyses and magnetic moment measurements. The nature of the complexes formed in ethanolic solution was study following the molar ratio method. From the spectral studies, monomer structures proposed for the nickel (II) and Zinc (II) complexes while dimeric structures for the chromium (III) and platinum (IV) were proposed. Octahedral geometry was suggested for all prepared complexes except zinc (II) has tetrahedral geometry, Structural geometries of these compounds were also suggested in gas phase by using
