avulsion injury of the flexor digitorum profundus (fdp) with concomitant fracture of the distal phalanx dorsal base is uncommon. simultaneous avulsion fractures of the insertion of this tendon associated with rupture of the tendon from the bony fragment and combination with dorsal base fracture is very rare and also complicated. a 36- year- old man fell and injured his right little finger. fdp ...

background and aims. the aim of this study was to compare flexural strength of specimens processed by conventional and injection-molding techniques. materials and methods. conventional pressure-packed pmma was used for conventional pressure-packed and injection-molded pmma was used for injection-molding techniques. after processing, 15 specimens were stored in distilled water at room temperatur...

a new series of transition metal complexes of co(ii), ni(ii), cu(ii) and zn(ii), has beensynthesized from the knoevenagel condensate schiff base ligand(l) derived from β-ketoanilideand furfural with o-phenylenediamine and diethylmalonate. structural features were determinedby spectral and analytical techniques. square-planar geometry has been adopted by thecomplexes except cobalt complex which ...

non-penetrating head injuries associated with skull base fractures can lead to the development of pneumocephalus upon airs ingress, which leads its course in the subarachnoid space. intracerebral air accumulation is rare and ensuses when a paranasal sinus fracture is associated with a ensues when a paranasal sinus fracture is associated with a nearby parenchymal contusion. a 25-year old man is ...

the condensation reaction of 5-(4-aminophenyl)-4-phenyl-1,2,4-triazole-3-thione with salicylaldehyde, 4-hydroxybenzaldehyde, 5-chlorosalicylaldehyde, 5-bromosalicylaldehyde, 2-nitrobenzaldehyde, 3-nitrobenzaldehyde, 4-nitrobenzaldehyde and 4-methoxybenzaldehyde in methanol results in series of new schiff bases. the structure of schiff bases were confirmed by 1h nmr, 13c nmr, ir and mass spectro...

statement of problem: fracture strength of a denture base resin is of great concern, and many approaches have been used to strengthen acrylic resin dentures. purpose: the aim of this study was to measure the transverse strength of a heat polymerized acrylic resin, after reinforcement with metal wire and two types of glass fibers. materials and methods: forty rectangular specimens (65.0×10.0×3.3...

new hetero-binuclear hg-cu schiff base complexes were prepared by reaction of 2,2'-[1,1'-(2,2-‎dimethylpropane-1,3-diyldinitrilo)-diethyldyne]diphenolato}copper(ii) (cul1) and 6,6'-x-2,2'-[(2,2-‎dimethylpropane-1,3-diyl)bis(nitrilomethanylylidene)]diphenolato copper(ii) [(x = ethoxy (cul2) and ‎methoxy (cul3)], with hgcl2 to give [cu(l1)hgcl2] (1), [cu(l2)hgcl2] (2), and [cu...

the clivus is the surface of a portion of the occipital and sphenoid bones in the base of the skull. (1)it is surrounded by the neurovascular structures of the brainstem, as well as internal carotid arteries. tumors of the clivus can be benign (chordoma)or malignant (chondrosarcoma).(2) chordomas are rare, aggressive, slow-growing, invasive, and locally destructive tumors that arise from the no...
