A major challenge for immunologists has been the development of vaccines able to augment both of humoral and cellular immune responses. One particularly promising approach is the prime–boost strategy, which has been shown to generate high levels of T-cell memory in animal models. In the present study, HIV-1 gp41 (662-683) loaded liposomes were used to determine how does prime–boost strategy would be beneficial for generation of humoral and cellular responses. BALB/c mice were immunized with HIV-1 gp41 (662-683) liposomes and 30 days later they received the booster doseof the same immunogen. HIV-1 gp41 (662-683) specific humoralresponse was evaluated pre-prime, 30days post-prime and 30 days post-boost by ELISA. HIV-1 gp41 (662-683) specific antibodies sharply jumped after boosting by ~40 foldcompared to that generated by priming. Similarly, self-boosting generated considerably HIV-1 gp41 (662-683) specific antigen secreting plasma cells in bone marrow. Overall, the results suggest that self-boosting is very important for generation of specific humoral response for HIV-1 gp41 (662-683). This prime-boost strategy shows a promise to induce both of specific-antibodies and specific antibody secreting cells in bone marrowfor weak immunogens like HIV-1 gp41 (662-683).

The κ-carrageenan/sodium alginate beads were prepared for drug delivery system. The presented study; describes the preparation of κ-carrageenan/sodium alginate beads and their feasibility as potential carriers for delivery of polysaccharide drugs was evaluated. Moreover, the pH sensitive behavior of beads was measured in simulated gastrointestinal tract condition. Furthermore, the hydrogel beads were loaded with polysaccharides extracted from naturalmushroom, and their release was monitored. This results showed that; the swelling ratio of beads indicated pH-dependent properties with maximum water absorbing at pH 7.4. Moreover, the highest amount of released polysaccharide was 27.2% at pH value 7.4 within 6 h. It was observed that the encapsulation of κ-carrageenan with sodium alginate reduced the premature release of drug in the stomach mimicked condition acidic pH and released the drug more specifically to the colon mimicked condition alkaline pH. Therefore, these results suggest that microcapsules could be further developed as effective drug delivery system with pH sensitive drug release ability.

Five fungicides (tebuconazole, fludioxonil, iprodione, azoxystrobin and flutolanil) were evaluated separately or in mixtures with the antioxidant (selenium) against Fusarium graminearum and Rhizoctonia solani which causing root rot diseases of wheat. Depend upon EC50 values of the tested fungicides, the in vitro studies showed that the descending order of fungicidal activity against F.graminearum growth was as follows;fludioxonil> tebuconazole > iprodione > azoxystrobin > flutolanil, while it was flutolanil >fludioxonil> tebuconazole > iprodione > azoxystrobin against R. solani growth.The two fungi tolerated high concentration of selenium. Interestingly, the fungitoxic activities of the tested fungicides were greatly increased by adding selenium to the fungicide- amended medium. In greenhouse trials, the fungicides were applied at rates of 1.5 and 3.0 g /kg seeds, while selenium was applied at 10 and 20 μg / ml (as seed treatments) alone or in combinations with fungicides for controlling root rot diseases. The results showed that all fungicides treatments significantly reduced diseases incidence and increased emergence and plant stands. Generally the addition of the antioxidant (Se) at 20μg / ml to the higher rate (3.0 g/kg seeds) of each fungicide caused significant reduction of the pre- and post- emergence damping off and subsequently increased plant survivals. However, the addition of Se to the low rate of each fungicide gave satisfactory fungicidal action as well as minimizing the environmental pollution.

Cowpea (Vigna unguiculata (L.) Walp.) is the most important grain legume crop grown in tropical and subtropical regions. Seeds of cowpea have a high nutritional value containing high amount of protein (23–29%). Seeds of 19 landraces of cowpea (Vigna unguiculata) were obtained from gene bank of Cairo University (11 landraces) and from Agricultural Research Station Kafr El-Sheikh (Sakha) (8 varieties). The seeds planted till maturity. Random amplified polymorphic DNA (RAPD) was assayed to determine the genetic variation of 19 varieties of cowpea cultivated in different regions of Egypt. A total of five random primers were used in the study. Amplification of genomic DNA of Egyptian cowpea landraces with these RAPD primers yielded 54 fragments that could be scored, of which 45 were polymorphic. Number of amplified fragments with random primers ranged from 4 (OP 856) to 14 (OP 880). Percentage polymorphism ranged from 75% (OP 856) to a maximum of 100% (OP 889, OP 868, Op 808 and OP 880), with an average of 95%. A dendrogram produced by the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) based on Jaccard‟s similarity coefficient revealed that the cowpea varieties divided into two groups which showed variability that may be exploited for crop improvement. The overall range of genetic similarities ranged from 0.48 to 0.93 in 19 landraces of cowpea which indicates there was high variability among the varieties. Based on genetic distance in RAPD analysis the landraces no. 9 and 12 appeared as most divergent and could be used in breeding programme of cowpea. It could be concluded that RAPD markers are important tools for genetic analysis for cowpea(Vigna unguiculata (L.) Walp.).

The first report about intestinal microsporidia from wild mammals in Egypt is herein present. A total of 134 fecal samples were separately collected from seven different mammalian species located in fifteen different localities,represented Western Desert, Nile Valley and Delta and Eastern Desert of Egypt. Microsporidian spores were obtained from the collected samples usingflotation technique and finally stained with modified trichrome (MT). Intestinal microsporidia were detected in 72.39% (97/134) of wild mammals. Moreover, rate of infection with intestinal microsporidia was 72.84% (59/81) in males and 73.08% (38/52) in females.The infection rates of intestinal microsporidia were 91.1%, 73.9%, 73.6%, 70%, 55.6% and 48.1% in red foxVulpes vulpes, the lesser Egyptian gerbilGerbillus gerbillus,the house mouseMus musculus, Sundevall's jirdMeriones crassus, Mackilligin's gerbilDipodillus mackilliginiand the Cairo spiny mouseAcomys cahirinus, respectively. The results also showed that the highest percentage of microsporidia was recorded in two mammalian species closely related to human habitats: red fox V. vulpes and G. gerbillus. In conclusion, the wild mammalian species which live in association with humans and fed on their contaminated diets were more susceptible to be infected with several microsporidian species than the other species that live in natural habitats away from humans.

Reproductive cycle of the two populations of Brachidontes pharaonis (Mytilidae: Bivalvia: Mollusca)at Adabia and Ain Sokhna (northern western coast of the Suez Gulf), was studied during the period from January to December 2014. The present results showed that sex is separated in this species, but the microscopic examinations are necessary for determination of gonads in both sexes. The first appearance for gonads was observed in males and females at 6.3and 6.5 mm shell length, respectively. However, the largest immature individuals reach 8.6 mm shell length. The overall sex ratio indicated to over dominant females at both sites, with 1:1.57 (males: females) at Adabia, increased slightly to 1:1.81 (males: females) at Ain Sokhna, with statistical significant differences (X2= 8.33 and 5.14 significant at P

Nanoparticles (NPs) not only offer a great possibility for biomedical application, pharmaceutics, but also may be used for novel diagnostic and therapeutic approaches. Currently, there are no data available regarding to what extent the degree of toxicity of gold nanoparticles (AuNSs). This study aimed to investigate the histopathological and ultrastructural effect of AuNSs size on the liver and kidney of female pregnant rats. To achieve that gold nanoparticles of 10 nm, 25nm and 50 nm were Interperitoneally injected in female rats at 48 hr during rat pregnancy. Forty adult female albino rats were divided into four equal groups: The first one served as a control group, the second received 75 mg/kg/day AuNSs as 10 nm in size, the third received 75 mg/kg/day AuNSs as 25 nm in size and the fourth received 75 mg/kg/day AuNSs as 50 nm in size, All groups were scarified after 19days from gestation where liver and kidney specimens were collected at the end of the experiment for histological and ultrastructural examination, AuNSs treated groups revealed wide spread histological and ultrastructural alterations in the liver and kidney structure as dilated and congested hepatic blood vessels, widespread vacuolated and ballooned hepatocytes with early apoptotic changes, pyknotic hyper chromatic irregular nuclei with deteriorated chromatin condensation. The distal convoluted tubule had shrunken pyknotic nuclei and margination of heterochromatin with irregular nuclear envelope. This study conculcated that all size of AuNSs caused side effect in the liver and kidney of pregnant rates.

Diabetes is a syndrome of impaired carbohydrate, fat and protein metabolism caused by either lack of insulin secretion or decreased sensitivity of the tissues to insulin. Diabetes mellitus is the most common endocrine disease worldwide. Diabetes mellitus was induced by injection streptozotocin intraperitonealy at dose 47 mg/kg body mass. The present study was designed to investigate the possible therapeutic effects of Balanites aegyptiaca (Heglig dates) and Persea americana (Avocado fruit) water extracts on some hematological and biochemical parameters in streptozotocin diabetic rats at doses 100 mg/kg and 500 mg/kg body mass respectively for 30 days. Treatment extracts were given orally through a gavage tube. The current results revealed a significant decrease in RBCs, WBCs counts, Hb concentration, MCHC, serum total protein, albumin, insulin and C-peptide level in diabetic rats. On the other hand a significant increase was recorded in MCV value, serum glucose and Hb A1c level in diabetic group in comparison with the control group. Treatment with Balanites aegyptiaca, Persea americana revealed an improvements in these parameters.

The present study was designed to determine the possible protective and therapeutic effects of olive oil and/or Ficus carica against radiation-induced cytological and histological changes in liver and Kidney of male albino rats. Irradiation was performed by whole-body exposure of rats to an acute single dose gamma radiation of 6 Gy. Irradiated rats received, via gavage, extra virgin olive oil (7.6 ml/kg b.wt), and/or extract of Ficus carica fruit (1 g/kg b.wt) before and/or after radiation exposure. Six rats were sacrificed on the 1st and 15th-day post-irradiation exposure at the control and treated irradiated subgroups. Time duration for this experiment was one month.The γ-Irradiation treated group revealedhisto pathological alterations in the hepatic and renal tissues on the 1st and 15th-day post-irradiation as compared to the control rats. The administration of the olive oil and/or Ficus carica showed beneficial results against the deleterious effects of γ-irradiation. A better ameliorative effect was noticed with the combined treatments that revealed the synergistic effect between them.In conclusion, the administration of the olive oil and/or Ficus carica provides considerable radioprotective and radiotherapeutic effects against whole body γ-radiation in male Wistar albino rats.
