Asthma is a chronic respiratory disorder in which immunological and structural cells play a role. The limits of conventional medicines necessitate the development of innovative therapeutic techniques for asthma. In the present study, we investigated the possible protective effect of cinnamic acid (CA) on ovalbumin-induced asthma in a mouse model. Sixty albino male mice BALB/c type weighing (20-30) grams were chosen at random and divided into five groups each one contains 12 animal: Group I: PBS/liquid paraffin control. Group II: asthma model group. Group III: cinnamic acid control group; mice received cinnamic acid (50 mg/kg) in liquid paraffin orally by gavage. Group IV: asthma model / group of (25 mg / kg) cinnamic acid; mice received (25 mg/kg) in liquid paraffin orally by gavage. Group V: asthma/ (50 mg/kg) cinnamic acid group; mice received cinnamic acid (50 mg/kg) in liquid paraffin orally by gavage. The experiment continued for 14 days. On day 15, broncho-alveolar lavage fluid, blood and lung tissue was collected. Total cell count, tissue TNF- α, IL -33, and serum IgE increased considerably after sensitization to ovalbumin (OVA), while GSH levels decreased significantly. On the other hand, administration of cinnamic acid in (25mg and 50mg/kg) has significantly decreased total WBC count, tissue TNF- α, IL -33, and serum IgE results, and a significant increase on GSH results. These findings suggest that cinnamic acid has a protective effect against OVA-induced allergic asthma in mice, possibly through its antioxidant activity and inhibitory activity on some proliferative modulating enzymes.
Regional immune response with mammary gland carcinoma was
studied statistically. However, the prognostic value remains
conflicting. Thirty mice were used in this study which infected
were with mammary gland carcinoma. The tumor size of the animals
under study were measured before and after laser irradiation by using
a vernier and compared these results were with that of non irradiated
animals with laser (control group)
The aim of this study was to evaluate the effect of low level laser
therapy (LLLT) on increasing the response of immune system by
stimulating the lymph node action to decrease the cancer cell activity
and then decreasing the tumor size of an infected mice.

The study aims to identify the impact of the round-robin strategy on the logical thinking of fourth-year middle school students in chemistry. Two groups were employed: an experimental group consisted of (30) students who were taught according to the round-robin strategy, and the control group consisted of (30) students who were taught according to the traditional method. The researcher adopted the experimental design with partial control by preparing the visual thinking test tool, which consists of (20) multiple-choice items, it was applied as a post-test on the research sample. The result showed that there was a statistically significant difference in favor of the experimental group, which was taught according to the Round Robin s

Show MoreIn this research, we studied the effect of concentration carriers on the efficiency of the N749-TiO2 heterogeneous solar cell based on quantum electron transfer theory using a donor-acceptor scenario. The photoelectric properties of the N749-TiO2 interfaces in dye sensitized solar cells DSSCs are calculated using the J-V curves. For the (CH3)3COH solvent, the N749-TiO2 heterogeneous solar cell shows that the concentration carrier together with the strength coupling are the main factors affecting the current density, fill factor and efficiency. The current density and current increase as the concentration increases and the
A theoretical calculation of the reorganization energies is demonstrated for semiconductor (TiOâ‚‚, ZnO) and organic dye (safranine T, and coumarin) with a variety solvent such that (water, 1Âpropanol, Formamide, Acetonitrile and Ethanol). The reorganization energy values for dye –semiconductor interface system are large in high polar solvent (water 741 .0 ï¬ , Acetonitrile 708 .0 ï¬ , Ethanol 669 .0 ï¬ ) and small in low polar solvent(1Âpropanol 635 .0 ï¬ . The reorganization energy in safranine T –semiconductor system is larger ( 635 741.0 ï€ )than in coumarin –semiconductor for with the same solvents ( 612

Background: The success and maintenance of indirect dental restorations is closely related to the marginal accuracy, which is affected by many factors like preparation design, using of different fabrication techniques, and the time of taking final impression and pouring it. The purpose of this in vitro study was to evaluate the effect of different pouring time of conventional impression on the vertical marginal gap of full contour zirconia crowns in comparison with digital impression technique. Materials and Methods: Forty sound recently extracted human permanent maxillary first premolar teeth of comparable size and shape were collected. Standardized preparation of all teeth samples were carried out to receive full contour zirconia crown re
