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.
The aim of the current study was to develop a nanostructured double-layer for hydrophobic molecules delivery system. The developed double-layer consisted of polyethylene glycol-based polymeric (PEG) followed by gelatin sub coating of the core hydrophobic molecules containing sodium citrate. The polymeric composition ratio of PEG and the amount of the sub coating gelatin were optimized using the two-level fractional method. The nanoparticles were characterized using AFM and FT-IR techniques. The size of these nano capsules was in the range of 39-76 nm depending on drug loading concentration. The drug was effectively loaded into PEG-Gelatin nanoparticles (≈47%). The hydrophobic molecules-release characteristics in terms of controlled-releas

The present study stresses two of the most significant aspects of linguistic approach: Pragmatics” and the “Speech Act Theory”, revealing its importance and the stages and levels of development through Hebrew language’s speech acts analysis including (political speech, the Holy Bible, Hebrew stories).
Chronologically, Pragmatics has always been the center of linguists’ interests due to its importance in linguistic decryptions, particularly, through “Speech Act Theory” that has been initiated and developed by the most prominent philosophers and linguistics.

Reducing of ethyl 4-((2-hydroxy-3-methoxybenzylidene)amino)benzoate (1) afford ethyl 4-((2-hydroxy-3-methoxybenzyl) amino)benzoate (2). Reaction of this compound with Vilsmeier reagent affords novel 2-chloro-[1,3] benzoxazine ring (3). The corresponding acid hydrazide of compound 3 was synthesized from reaction of compound (3) with hydrazine hydrate. Newly series of hydrazones(5a–i) were synthesized from reaction of acid hydrazide with various aryl aldehydes. Antibacterial activity of the hydrazones wassecerned utilizing gram-negative and gram-positive bacteria. Compound (5b) and (5c) exhibited significant antibacterial ability against both gram-negative and gram-positive bacteria, while the compounds(5a) showed mild antibacterial activit

CD40 is a type 1 transmembrane protein composed of 277 amino acids, and it belongs to the tumor necrosis factor receptor (TNFR) superfamily. It is expressed in a variety of cell types, including normal B cells, macrophages, dendritic cells, and endothelial cells, as a costimulatory molecule. This study aims to summarize the CD40 polymorphism effect and its susceptibility to immune-related disorders. The CD40 gene polymorphisms showed a significant association with different immune-related disorders and act as a risk factor for increased susceptibility to these diseases.

Date palm silver nanoparticles are a green synthesis method used as antibacterial agents. Today,
there is a considerable interest in it because it is safe, nontoxic, low costly and ecofriendly. Biofilm bacteria
existing in marketed local milk is at highly risk on population health and may be life-threatening as most
biofilm-forming bacteria are multidrug resistance. The goal of current study is to eradicate biofilm-forming
bacteria by alternative treatment green synthesis silver nanoparticles. The biofilm formation by bacterial
isolates was detected by Congo red method. The silver nanoparticles were prepared from date palm
(khestawy) fruit extract. The formed nanoparticles were characterized with UV-Vis
