La réalité augmentée désigne une interface virtuelle, en 2D ou en 3D, qui vient enrichir la réalitéen y superposant des informations complémentaires. Les domaines d’applications touchent aussibien les loisirs (avec les jeux vidéo) que l’éducation, la médecine, mais aussi l’industrie. Ce dernièrea était donc notre choix de thème pour notre application qui a pour but d’aider les vendeurs etles clients d’un magasin de meuble a faire leur choix. Cela reste malgré tout un domaine nouveauencore peu connu du grand public.

Introduction: In Palestine, the first leading cause of death is cardiovascular diseases, and cancer is ranked as the second leading cause of death. Colorectal cancer is ranked as the second type of cancer among Palestinian patients. Cancer care is improving in Palestinian hospitals with time; however, services like palliative care, targeted therapy, bone-marrow transplantation, and individualized therapy are still limited. The study aims to assess the colorectal cancer stages, treatment protocols, and the survival of patients in Palestine.Methodology: This is a retrospective study through data collection from medical records in a hospital specialized in cancer patients' care. Patients with confirmed colorectal cancer (stages I, II, III, IV) undergoing surgical or medical treatment were included in the study. Data collection was standardized by using Data Collection Form to gather information from included medical records. The disease outcomes after treatment were categorized into six categories, namely, Death, Cure, Disease Progression, Disease Recurrence, Under-treatment, or Unknown outcomes. Statistical analysis was performed using Statistical Package for Social Sciences (SPSS version 21).Results: A sample of 252 patients with colorectal cancer from An-Najah National University Hospital (NNUH) was collected, males were 143 (56.7%), their age was between 27 – 86 years with a mean of 60.64 (±11.4) years. Most of the patients had colon cancer only (183 patient, 72.6%) and (29 patient, 11.5%) had rectal cancer only, while the rest had both rectal and colon cancer (40 patients, 15.9%), most of them were at stage IV (159 patients, 63.1%). Surgery was the most prevailing mode of treatment for colorectal cancer patients (230; 91.3%), on the other hand, in patients who received chemotherapy, FOLFOX (folinic acid, fluorouracil, oxaliplatin) was more prevalent among patients and the physicians tend to choose it compared to FOLFIRI (folinic acid, fluorouracil, irinotecan). The mortality of the disease was high as many patients (41.3%) have died within a short interval between diagnosis and death. Worth mentioning that there was an apparent delay in the diagnosis of the disease as most patients were diagnosed at a later stage which has a poor prognosis. Regression analysis of days between last visit and diagnosis date and the type of treatment received (Chemotherapy, Surgical Treatment, Radiotherapy) (R2 = 0.035) surgical treatment had the longest days between diagnosis and last visit and this was significant (p = 0.033). Surgical treatment had a positive impact on increasing the days of survival and it was significant (p = 0.021). A Chi-square analysis of the stage at diagnosis and the prognosis of CRC patients using existing data revealed that there is a significant difference (p <0.05) between the stage at diagnosis and the disease outcome. On the other hand, Chi-square analysis for the chemotherapy protocol used among patients in comparison with disease outcomes, cure rates were highest with the use of FOLFOX (26.7%), death rates were similar between FOLFIRI and FOLFOX patients. These results were significantly different (p<0.05).Conclusions: A high percentage of patients were diagnosed in advanced disease stages. The modes of treatment generally were adopted from international guidelines, however, the cure rates and good disease prognosis were not high, the disease mortality rate was high. More studies need to be undertaken to investigate the actual application of chemotherapy protocols and involve clinical pharmacists in the chemotherapy protocol choice, dosing, frequency, follow-up. As a result, the present analysis of Palestine's colorectal cancer pattern advocates for a wide range of treatments to lower the disease's burden. These include investments in public awareness campaigns aimed at the general public and primary care professionals, intending to increase understanding of colorectal cancer symptoms and risk factors, as well as the merits of screening, and promotion of healthy lifestyles in order to avoid this serious illness. In order to diagnose the disease much earlier which makes health care providers intervene earlier to promote a better prognosis.

This study is carried out to investigate the protective role of Glutathione on the reproductive system induced by D-galactose overload in female rats. injected intraperitoneally (IP) with 100 mg/kg B .W of D-galactose and GSH for 45 day.Twenty female (20) rats were divided into four groups (20/5), the first group was injected with normal saline for 45 day and served as control group(G1), rats in the second group were injected intraperitoneally (IP) with 100 mg/kg B .W of D-galactose (G2). While animals of the third group were (G3) injected intraperitoneally (IP) with 100 mg/kg B .W of Glutathione , rat in the fourth group (G4) were injected intraperitoneally (IP) with 100 mg/kg B .W of D-galactose and Glutathione .Fasting blood samples were collected by cardiac punctures technique at 45 day of experimental for measuring: biomarker of oxidant and antioxidant including serum Glutathione (GSH) , Malondialdehyde (MDA) concentrations ,Superoxide dismutase (SOD) and Catalase (CAT) .serum hormones follicle stimulating hormone (FSH) ,Luteinizing hormone (LH),Estrogen hormone and Progesterone hormone serum Lipid profile ,Low density lipoprotein (LDL),High density lipoprotein (HDL),Triglycerides(TAG),Total Cholesterol(TC) and Very Low density lipoprotein (VLDL),D-serum GlucoseThe results before pregnant revealed to a significant (p≤0.05) increase in Glucose level in G2 compared with G1,G3 and G4 also showed a significant increase in MDA,TC,TAC,LDL-C,VLDL-C in G2 group comparing with other groups ,serum estrogen showed a significant (p≤0.05) increase in G2 comparing with control group. And showed significant decrease in HDL-C ,SOD.CAT and GSH in G2 comparing with G1,G3 and G4 groups , serum FSH showed a significant decrease in G2 group comparing with G1 and G3groups ,while serum LH in G3 and G4 comparing with other groups, also serum progesterone calculated showed a significant decrease in G2 group when comparing with G1, G3 and G4groups .While results in our study after seven day of pregnant showed a significant decrease (p≤0.05) in serum LH and FSH level in G2 group comparing with G1.G3 and G4 groups ,also a significant decrease in serum estrogen and progesteron in G2 group comparing with other groups .The research revealed to a significant decrease in the level of HDL-C. GSH,SOD and CAT concentration in the G2 group comparing with other groups, while showed a significant(p≤0.05) increase in the serum level of progesterone, TC, TAG, LDL-C,VLDL-C and MDA concentration in G2 group compering with G1,G3 and G4 groups .The histological change, it was the effect of D-galactose on the ovary, it affected the rate of ovulation and the number of mature follicles in the ovary. On the other hand, it had no effect on the implantation of embryos in the uterus of pregnant rats, and we noticed in the histological sections of the ovaries and uterus of the groups that were treated with glutathione, the results were in contrast to D-galactose only, the ovary was at the peak of its activity, and the uterus and implantation were in the correct form.In conclusion, the results of this study confirm the protective role of GSH against the D-galactose over load in the reproductive system and hormones before and during early pregnancy

L’observation montre que l’intensité avec laquelle un séisme est ressenti en un lieu donné dépend, dans une large mesure, de la nature des terrains traversés par les ondes sismiques et des conditions locales. Il convient donc d’adapter le spectre de réponse à utiliser dans les calculs à la nature du site considéré. Par ailleurs, il est important de tenir compte de l’interaction sol-structure.Dans ce travail, nous montrons qu’on peut prendre en compte l’interaction sol-structure sans modéliser celle-ci par ressorts ou autres. Pour cela, on tient compte de l’influence de la modification de l’action sismique par les différents spectres de réponse proposés par le Règlement Parasismique Algérien (RPA99v03) sur la réponse des structures en portiques
