Mycosis Fungoides Diagnosis Using TOX Versus Old Panel Immunohistochemical Markers

Background: For primary cutaneous lymphoma, mycosis fungoides (MF) is the most prevalent form with skin-homing T cells plus clonal proliferation of CD4. In many CTCLs, thymocyte selection associated with the HMG-box (TOX) is an uncontrolled gene, together with MF in comparison with controls. Early mycosis fungoides is difficult to diagnose, and, its distinction from inflammatory diseases is sometimes impossible. Objective: In this study, we compared the TOX vs C7 and CD4 expression as an early mycosis fungoides diagnostic markers & to assess their ability to differentiate Mycosis fungoides from benign cutaneous inflammatory diseases (BCID). Materials and methods: 60 patients who had been previously diagnosed as MF (30 cases) and BCID (30 cases). All were evaluated histopathologically using H & E and immunohistochemically staining for TOX, CD7 & CD 4. Results: There was statistically significant difference between MF and BCID with increased TOX, CD7 & CD4 expression among MF than among BCID and ability of TOX to detect all true positive cases (100.0%) compared to 83.3% for CD4 and 13.3% for CD7. TOX had the highest sensitivity (100.0%) and accuracy (88.3%) followed by CD4 with sensitivity of 88.3% and accuracy of 66.7%, (P < 0.001). Conclusion: TOX had the highest sensitivity (100.0%) & accuracy (88.3%) followed by CD4 with sensitivity of 88.3% and accuracy of 66.7%. Our results suggest that TOX is a useful marker in diagnosis of MF & differentiating it from BCID

Enhanced Abiotic Stress Tolerance of Vicia faba L. Plants Heterologously Expressing the PR10a Gene from Potato

Pathogenesis-related (PR) proteins are known to play relevant roles in plant defense against biotic and abiotic stresses. In the present study, we characterize the response of transgenic faba bean (Vicia faba L.) plants encoding a PR10a gene from potato (Solanum tuberosum L.) to salinity and drought. The transgene was under the mannopine synthetase (pMAS) promoter. PR10a-overexpressing faba bean plants showed better growth than the wild-type plants after 14 days of drought stress and 30 days of salt stress under hydroponic growth conditions. After re-moving the stress, the PR10a-plants returned to a normal state, while the wild-type plants could not be restored. Most importantly, there was no phenotypic difference between transgenic and non-transgenic faba bean plants under well-watered conditions. Evaluation of physiological parameters during salt stress showed lower Na+-content in the leaves of the transgenic plants, which would reduce the toxic effect. In addition, PR10a-plants were able to maintain vegetative growth and experienced fewer photosystem changes under both stresses and a lower level of osmotic stress injury under salt stress compared to wild-type plants. Taken together, our findings suggest that the PR10a gene from potato plays an important role in abiotic stress tolerance, probably by activation of stress-related physiological processes

Evaluation of Hepatoprotective Activity of Adansonia digitata

The methanol extract of the fruit pulp of Adansonia digitata L. (Malvaceae) was examined for its hepatoprotective activity against liver damage induced by acetaminophen in rats. The principle depends on the fact that administration of acetaminophen will be associated with development of oxidative stress. In addition, hepatospecific serum markers will be disturbed. Treatment of the rats with the methanol extract of the fruit pulp of Adansonia digitata L. prior to administration of acetaminophen significantly reduced the disturbance in liver function. Liver functions were measured by assessment of total protein, total bilirubin, ALP, ALT, and AST. Oxidative stress parameter and antioxidant markers were also evaluated. Moreover, histopathological evaluation was performed in order to assess liver case regarding inflammatory infiltration or necrosis. Animals were observed for any symptoms of toxicity after administration of extract of the fruit pulp of Adansonia digitata L. to ensure safety of the fruit extract

Molecular Diagnosis of Toxoplasmosis in Non Immune Pregnant Females

BACKGROUND AND AIM: Infection with the protozoan parasite Toxoplasma gondii has a worldwide distribution. Congenital infection is the most important part of the disease burden due to Toxoplasma infection in humans. Early diagnosis of maternal infection helps to prevent severe complications of toxoplasmosis. In the present study, three PCR assays (conventional, nested & quantitative) were evaluated for diagnosis of recent toxoplasmosis based on detection of Toxoplasma B1 gene.MATERIAL AND METHODS: The present study was carried out on 150 pregnant females who were serologically negative for anti-Toxoplasma IgG and IgM antibodies.RESULTS: The results revealed that out of 12 true positive cases (by 2 out of the 3 PCR protocols), 8 cases were positive by cPCR, 11 cases were positive by nPCR and 12 cases were positive by qPCR. Accurate estimation of genomic Toxoplasma DNA in positive samples was achieved by qPCR. In general, PCR assays offer a sensitive alternative of serological methods for diagnosis of recent maternal toxoplasmosis. In addition, qPCR decreases the risk of contamination of PCR products being a closed tube method and helps in estimation of infection load.CONCLUSIONS: We recommend screening of high-risk pregnant women by qPCR for early diagnosis of toxoplasmosis and proper management

PATELLAR REALIGNMENT AND FUNCTIONAL PERFORMANCE IN PATIENTS WITH PATELLOFEMORAL PAIN SYNDROME

Background: Patellar taping is used for pain relief in patients with patello-femoral pain syndrome (PFPS). Yet, there is lack of knowledge regarding its effect on the functional performance. The purpose of the study was to examine the effects of therapeutic patellar taping on the Visual Analogue Scale (VAS) pain scores, number of bilateral squats, and stair climbing time in patients with PFPS. Methods: 30 female patients with PFPS with mean age 20.3± 1.46 years, weight 66.1± 9.68 kg, height 165.83 ± 3.89 cm and BMI 23.91 ± 3.50kg/m2 participated in the study. The subjects were tested randomly under three taping conditions;namely therapeutic, placebo and no-tape. The tested limb was determined to be the affected limb in patients with unilateral affection, and the symptomatic limb in patients with bilateral affection. Data was collected using the Visual Analogue Scale (VAS), Bilateral Squat Test and Timed Stair Ambulation Test. Results: Repeated measures Multivariate Analysis of Variance (MANOVA) revealed that the number of bilateral squats increased significantly (p<0.05) and the VAS scores and stair climbing time decreased significantly with the use of therapeutic tape compared with the other two tested tape conditions. Additionally, the VAS pain scores decreased significantly with placebo tape use compared with no tape, with no significant difference (p>0.05) in between for the number of bilateral squats and stair climbing time. Conclusion: The findings indicated that therapeutic patellar taping is effective in improving functional performance and reducing pain in patients with patellofemoral pain syndrome (PFPS)

Philosophical strategies to design advertising campaigns to support the moral and value system of society

Recently, societies are exposed to many socio-economic and political changes that, in turn, affect the social component and psychological structures of individuals' structure, affecting the behavioral and moral and moral systems of society. The effects of these changes on the members of society vary between the negative and that lead to the deviation of social values ​​and ethics from the right track, which needs to modify and evaluate and change, and between the positive effects and need to be strengthened and rooted among the members of the community, which needs mechanisms for correction, Effective advertising communication becomes one of these mechanisms for change, through targeted advertising campaigns aimed at restoring the moral and value system of society to its natural course, as the primary driver of the motivations and reactions of members of this society. Because these targeted campaigns are loaded with many messages and codes that affect the behavior within this society, and this behavior is supposed to be positive according to the philosophy adopted by these campaigns, there is a possibility that there is a problem in the communication process and the interpretation of communication messages wrong, Messages and their positive impact, which is usually contrary to the objectives adopted by these campaigns, Here is the problem of research, which is to answer the following questions: 1.       What are the mechanisms that advertising campaigns which support the ethical and value system in society work through? 2.       What are the design strategies used in these campaigns? 3.       What are philosophical theories (dimensions) should these campaigns contain? The research aims to shed light on the nature of these campaigns and the development of philosophical strategies to design these campaigns as part of the social responsibility of their Producers to promote and support the positive behaviors within the society, as well as to study how to design a mechanism to design these campaigns in line with the moral and value system of society

Anti-hyperglycaemic effect of <i>Phragmenthera austroarabica</i> A.G.Mill. & J.A.Nyberg extract in streptozotocin-induced diabetes in rats

<div><p>This study was undertaken to investigate the hypoglycaemic activity of <i>Phragmenthera austroarabica</i> A.G.Mill. & J.A.Nyberg extract and evaluate its possible antioxidant and anti-hyperlipidaemic effect in type 2 diabetic animal model. Type 2 diabetes was induced by a high-fat diet followed by injection with streptozotocin. Diabetic adult male Wistar rats were allocated into three groups and treated with pioglitazone HCl (PIO) or the extract of <i>P. austroarabica</i> A.G.Mill. & J.A.Nyberg (250 or 500 mg/kg b.wt.). In addition, a normal control group and a diabetic control group were used for comparison. Blood glucose, insulin resistance, oxidative stress parameter, antioxidant markers and serum lipids were evaluated. The extract of <i>P. austroarabica</i> A.G.Mill. & J.A.Nyberg exhibited a significant hypoglycaemia associated with antioxidant and anti-hyperlipidaemic effects in diabetic rats.

The extract revealed no symptoms of toxicity. It is concluded that this plant might be considered as an excellent candidate for future study on diabetes mellitus.</p></div

Impact of chitosan on shoot regeneration from faba bean embryo axes through its effect on phenolic compounds and endogenous hormones

Legume crops have been the primary targets for improvement by genetic transformation due to their importance for human and animal consumption worldwide. Many of these important legume crops were difficult to genetically engineer especially faba bean crop, mainly due to high phenolics content and their recalcitrance to in vitro regeneration. Therefore, a series of experiments were performed in order to evaluate the growth , morphological changes and production of phenolics in the in vitro plantlets of five Egyptian faba bean cultivars (Giza 843, Sakha 1, Sakha 3, Nubaria 2 and Nubaria 3). The obtained results revealed that cultivars Nubaria 2 and Skha 3 had the highest regeneration frequency (85.3% and 78.6%), respectively. Also, both cultivars showed high growth parameters and low in total phenols concentration. Therefore, these cultivars considered as promising candidates to Agrobacterium mediated genetic transformation experiments. The effect of different levels of chitosan (0, 2, 4, 8, 15, 30, 60, and 120 mg chitosan/l) on shoot regeneration from mature embryo axes of cv. Nubaria 2 were studied. The obtained results indicated that high levels of chitosan have lethal effect on the development of embryo axes tissues and the plantlets showed morphological abnormalities. However, low levels of chitosan 2 mg /l and 4mg /l in combination with 4.5 mg/l BAP increased the shoot regeneration. Moreover, the total soluble phenols were increased by increasing the age of the faba bean plantlets (six weeks old) cultured in vitro on a medium containing low level of chitosan (2, 4 and 8 mg chitosan/l) as compared with plantlets did not expose to chitosan. HPLC analysis showed changes in the polyphenols concentrations and the concentration of Gibberellic acid (GA3) and Abscisic acid (ABA) in faba bean plantlets that exposed to low levels of chitosan (2, 4 and 8 mg chitosan /l) were increased as compared with control plantlets. The obtained results indicated that the concentration of phenolic compounds, GA3 and ABA in the extracts were increased in the faba bean plantlets that exposed to low levels of chitosan.file: :Users/u0129515/Sync/My_list_publication/Abeer, 2020.pdf:pdf keywords: ABA,Embryo Axes,GA3,Phenols,Regeneration Frequenc
