The number of endangered species has been increased due to shifts in the agricultural production, climate change, and poor urban planning. This has led to investigating new methods to address the problem of plant species identification/classification. In this paper, a plant identification approach using 2D digital leaves images was proposed. The approach used two features extraction methods based on one-dimensional (1D) and two-dimensional (2D) and the Bagging classifier. For the 1D-based methods, Principal Component Analysis (PCA), Direct Linear Discriminant Analysis (DLDA), and PCA + LDA techniques were applied, while 2DPCA and 2DLDA algorithms were used for the 2D-based method. To classify the extracted features in both methods, the Bagging classifier, with the decision tree as a weak learner was used. The five variants, i.e. PCA, PCA + LDA, DLDA, 2DPCA, and 2DLDA, of the approach were tested using the Flavia public dataset which consists of 1907 colored leaves images. The accuracy of these variants was evaluated and the results showed that the 2DPCA and 2DLDA methods were much better than using the PCA, PCA + LDA, and DLDA. Furthermore, it was found that the 2DLDA method was the best one and the increase of the weak learners of the Bagging classifier yielded a better classification accuracy. Also, a comparison with the most related work showed that our approach achieved better accuracy under the same dataset and same experimental setup.

Mahmoud, A. M., and A. I. Tanios, " Pathogenicity of Aeromonas hydrophila in chickens", Egyt. J. of Comp. Path. & Clinical Path., , vol. 21, no. 3 , pp. 88-110, 2008. Abstract

.Seventeen isolates of Aeromonas hydrophila were isolated from 250 commercial broiler chicks with an incidence of 6.8 %. Most A. hydrophila isolates (88.24 %) were positive for exotoxin assay and congo red binding test, while 52.94 % were positive for crystal violet binding activity. Most strains of A. hydrophila were sensitive to chloramphenicol, ciprofloxacin and norfloxacin followed by gentamicin and neomycin while nalidixic acid, tetracycline, streptomycin and trimethoprim sulphamethoxazole had moderate effect. On the other hand, all A. hydrophila strains were resistant to amoxicillin, cephalothin, erythromycin and penicillin G. All chicks infected with 1.5 X 109 organisms via subcutaneous and yolk sac were dead within 24 h. A. hydrophila was isolated from most organs. The lesions observed included congestion in the internal organs and few cases showed hepatic and muscular petechiae. Histopathological examination of experimentally infected chicks revealed severe necrosis in hepatic, splenic and muscular tissue in the two days old chicks. The ultrastructural study of this group showed presence of the bacilli inside the hepatocytes and macrophages with marked cellular changes. An attempt was made to determine a correlation between level of exposure and mortality. It was found that the mortality rate was relatively high (52.5 %) than in lower dose (35 %). A. hydrophila was isolated from most organs examined. Marked degenerative and necrobiotic changes in both hepatic and splenic tissue and characteristic muscular lesions manifested by muscular hemorrhage, degeneration, oedema and myositis in low dose treatment group. In the group injected with high dose, the lesions were more severe and characterized by diffuse areas of necrosis in hepatic tissue, thrombus formation in the blood vessels together with large number of bacterial colonies and bacilli in the hepatic tissue. Marked muscular necrosis and myophagia were also noticed. The ultrastructural study using transmission electron microscope for this group showed heterocells and hepatocytes contain bacilli. In other cases, the bacilli were present in the phagosomes of phagocytic cells in the splenic tissue. Cytopathological lysis was common evidence in the examined cells.

I, M., D. A, A. A, H. D, and S. T.M, " THE EFFICACY OF CERVICAL LORDOSIS REHABILITATION FOR NERVE ROOT FUNCTION, PAIN, AND SEGMENTAL MOTION IN CERVICAL SPONDYLOTIC RADICULOPATHY", WCPT, Holland, 21 June 2011. Abstract

Purpose: This study was conducted to test the hypothesis that improvement of cervical lordosis in CSR, using 3-point bending traction, will improve the clinical features in a sample population of patients suffering from Cervical Spondylotic Radiculopathy( CSR )with defined cervical hypo-lordosis.
Relevance: This study assists in the understanding of the association between sagittal curve alignment and lasting improved function providing physiotherapists with a guidelines for proper rehabilitation of CSR.
Participants: Thirty patients with lower CSR and with a cervical hypo-lordosis were included in the study. The patients were assigned randomly into two groups of equal number, study and control groups.
Methods: Both groups received stretching exercises and infrared radiation; additionally the study group received 3 point bending cervical traction. Treatments were applied 3 x per week for 10 weeks after which a 12 week follow up was performed. The peak to peak amplitude of dermatomal somatosensory evoked potentials (DSSEPS), absolute rotation angle (ARA C2-C7), cervical flexion-extension kinematics analysis, and visual analogue scale (VAS) were measured for all patients at three intervals (initial, after 10 weeks of treatment, and at follow up of 3 months).
Analysis: The outcome measure of ARA, pain, peak to peak DSSEPS, and kinematics analysis of cervical spine were measured using repeated measures one-way ANOVA to compare measurements made at three intervals.
Results: In the study group, an increase in cervical lordosis (ARA C2-C7) was found (p< 0.0001, F=49.81) and maintained at follow up. No statistically significant improvement in lordosis was found for the control group. A Significant reduction in VAS for study group after 10 weeks of treatment and at 12 weeks follow up was found. In contrast, there was a less significant decrease in post treatment VAS and the follow up measures revealed a significant increase in the VAS score towards initial baseline values. An inverse linear correlation between increased lordosis and VAS was found (r=-.49; p=0.0059) for both groups initially and maintained in the study group post treatment (r=-.6; p=0.0138). At 10-week follow up, we found statistically significant improvements in DSSEPS for both groups (one way ANNOV, p< 0.0001). However, at 12 week post treatment follow up, only the study group showed statistically significant improvement compared to initial (p < 0.006) whereas the control group values returned to baseline measurement (p<0.153). We identified a linear correlation between initial DSSEPs and ARA for both groups (r=.65; p<0.0001), where as this relationship was only maintained in the study group at final follow-up (r=.55; p=0.033).
Conclusions: Improved lordosis in the study group was associated with significant improvements in nerve root function, VAS rating, and translational and rotational motions of the lower cervical spine. Only in the study group were the results maintained at long-term follow up.
Implications: Appropriate physical rehabilitation for CSR should include cervical sagittal curve correction, as it is may to lead greater and longer lasting improved function.

Background: Although Alzheimer’s (AD) dementia was considered to be the most common form of dementia, vascular cognitive impairment has been found to be more common than previously thought. Inflammatory cytokines has been proved to be related to both mild cognitive impairment (MCI) and vascular cognitive impairment (VCI). Objective: Find a difference in inflammatory cytokines between MCI and VCI and the possibility to use them as biomarkers to differentiate between them. Methods: Thirty-seven Egyptian patients with variable degree of cognitive impairment were included. Patients were primary selected using the mini-mental state examination. Patients were divided into two groups (MCI) and (VCI) by NINDS-AIREN criteria and MRI brain. Serum was analyzed for CRP, IL-1B, IL-6 and IL-16 and CSF analyzed for IL-1β, IL-6, IL-16. Results: No difference was found in proportion of patients with abnormally elevated serum level of IL-1β, IL-6, IL-16 and C-reactive protein (CRP) between both groups. IL-6 was found abnormally elevated in a higher proportion of patients with MCI compared to patients with VCI. Conclusion: IL-6 elevation in CSF of MCI may be used as a biomarker to differentiate it from VCI. [Egypt J Neurol Psychiat Neurosurg. 2013; 50(2): 195-198]
