« Africa Rising ». Question de classe ou de finance ?
Authors: Roitman Janet , Labzaé Mehdi 
Published: June 2021

La notion d’« Africa Rising », qui renvoie à la formation d’une nouvelle classe moyenne et annonce une nouvelle ère pour le continent, suscite de nombreux débats. Les économistes du développement se sont attelés à mesurer l’ampleur de la classe moyenne, pendant que les anthropologues et les sociologues ont critiqué cette démarche pour son économicisme. Cela a enfermé le débat dans une opposition entre le quantitatif et le qualitatif. Il manque dès lors une discussion sur les motivations mêmes qui sous-tendent la revendication d’une Afrique émergente. Qui a besoin d’une définition de la classe moyenne ? Répondre à cette question amène à montrer que la classe moyenne est une catégorie utile au monde de la finance pour développer les marchés de capitaux sur le continent.
La comtesse Dash : masques et visage
Authors: Hong Ji Eun 
Published: June 2021

Oubliée au profit d’écrivains comme Dumas à qui elle prêtait sa plume, Gabrielle du Poilloüe de Saint-Mars (1804-1872) ne s’est pas contentée de se masquer derrière des identités d’emprunt ; elle a fait du masque un leitmotiv de son œuvre. Le présent article entend montrer combien, pour cet auteur, écrire sur le masque et sous le masque permet de préciser une poétique, plus encore qu’une simple image esthétique. La comtesse montre la comédie humaine à l’œuvre, avec ses vanités, et n’hésite pas à se référer à La Rochefoucauld pour adopter un masque auctorial inattendu : celui du moraliste. Le motif du bal masqué lui fournit en outre un motif romanesque et symbolique exemplaire. Au terme de l’œuvre comme de la vie de la comtesse Dash, la désillusion semble la même conclusion pessimiste : les visages démasqués ne tiennent pas leurs promesses, le temps et la mort mettent fin au carnaval.

Authors: Taleb Aya , Al-Sayyed Rizik M. H. , Al-Bdour Hamed S. 
Published: June 2021

In this research, a new technique to improve the accuracy of the link prediction for most of the networks is proposed; it is based on the prediction ensemble approach using the voting merging technique. The new proposed ensemble called Jaccard, Katz, and Random models Wrapper (JKRW), it scales up the prediction accuracy and provides better predictions for different sizes of populations including small, medium, and large data. The proposed model has been tested and evaluated based on the area under curve (AUC) and accuracy (ACC) measures. These measures applied to the other models used in this study that has been built based on the Jaccard Coefficient, Katz, Adamic/Adar, and Preferential attachment. Results from applying the evaluation matrices verify the improvement of JKRW effectiveness and stability in comparison to the other tested models. The results from applying the Wilcoxon signed-rank method (one of the non-parametric paired tests) indicate that JKRW has significant differences compared to the other models in the different populations at <strong>0.95</strong> confident interval.

Ultrasound-guided transrectal implantation of fiducial markers for image-guided radiotherapy of prostate cancer without local anesthesia
Authors: Sen Cenk Ahmet 
Published: June 2021

Purpose:
The present study evaluates procedure-associated pain and side effects in the gastrointestinal–genitourinary system in patients with early-stage prostate cancer who were treated with image-guided radiotherapy (IGRT), accompanied by an ultrasound-guided transrectal implantation of fiducial markers, without local anesthesia.

Materials and Methods:
A total of 46 patients who referred to our clinics between 2012 and 2017 with a diagnosis of early-stage prostate cancer were included in the study. Before undergoing radiotherapy, all patients were implanted with three intraprostatic fiducial markers through the ultrasound-guided transrectal approach without local anesthesia. The patients underwent radiotherapy after the clinical target volumes were established, in accordance with the respective risk groups, and localization of the markers was confirmed before each therapy session. The levels of procedure-associated pain and side effects were graded immediately after the procedure through the use of a patient-based scoring system.

Results:
The faces pain scale – revised version was used for the measurement of the severity of procedure-associated pain. Of the total study sample, the facial expressions of 38 patients (35%) corresponded to level 0 in the study, seven (15%) to level 2, and a single patient (2%) to level 4. None of the facial expressions of the patients corresponded to levels 6, 8, or 10. The evaluation of procedure-related genitourinary and gastrointestinal system side effects indicated that nine patients (20%) experienced side effects, while no side effects were reported in 37 patients (80%). The reported side effects included rectal bleeding in two patients (4%), dysuria in three patients (6%), hematuria in five patients (11%), and frequent urination in five patients (11%). None of the patients experienced fever or hematospermia. All side effects were reported by the respondents as “a little,” while only one patient answered positively to the question on the frequency of urination. Among the patients who answered “yes” and “a little” to the questions evaluating genitourinary and gastrointestinal system side effects, the severity of these events was reported as Grade 1, corresponding to mild adverse, in only 9 (20%) patients. None of the patients experienced a Grade 2 or higher severe adverse event. In the comparison of the severity of pain of the patients during the fiducial marker procedure without local anesthesia with the severity of pain during the biopsy, 24 patients (80%) reported “lower” levels of pain, while five patients (20%) reported “equal” levels of pain. None of the patients stated that they had experienced “more” pain.

Conclusion:
IGRT accompanied by an ultrasound-guided implantation of fiducial markers without local anesthesia can be considered a safe method, given the associated acceptable levels of pain, low side effect profiles, and high prostate-specific antigen control rates.

Authors: El-Hanafy Ghada M. , Nada Hanan R. , Rashed Laila A. , Mousa Marwa F. , Elmasry Maha F. 
Published: June 2021

Background
Autophagy is a lysosomal degradative process that is essential for the cell viability, homeostasis, and maintenance.

Objective
To measure microtubule-associated protein 1 light chain 3 (LC3)-I, LC3-II, and beclin 1 as indicators of autophagy and superoxide dismutase (SOD) and malondialdehyde (MDA) as indicators of oxidative stress in patients with vitiligo.

Patients and methods
This comparative case–control study was conducted on 20 patients with nonsegmental vitiligo as well as 20 controls. LC3-I, LC3-II, and beclin 1 tissue expressions were detected by western blot analysis, whereas MDA and SOD were measured by the colorimetry method in the tissue homogenate.

Results
The LC3-I, LC3-II, beclin 1, and SOD levels were significantly lower in lesional skin than nonlesional skin of patients as well as both lesional and nonlesional skin of patients than controls (P<0.001). On the contrary, the level of MDA was significantly higher in lesional skin than nonlesional skin of patients as well as both lesional and nonlesional skin of patients than controls (P<0.001).

Conclusion
Downregulated autophagy as evident by downregulated levels of autophagic markers together with dysregulated oxidative stress species could play a role in the pathogenesis of vitiligo, and optimizing autophagy could open a new era in vitiligo treatment.
Novel subcision technique combined with either microneedling or trichloroacetic acid 35% peeling for acne scars
Authors: Zayed Amira A. , Abelghafar Rasha A. , Hehazy Ahmed I. , Orabi Sarah , El-Mesidy Marwa S. 
Published: June 2021

Background
Challenging treatment of acne scars makes it a must to have a plan for each case specifically. Subcision breaks the fibrous strands tethering the scar but is followed by recurrence. Chemical peeling and microneedling are other treatment options.

Objectives
To evaluate a new subcision technique combined with either microneedling or peeling in the treatment of acne scars.

Patients and methods
A total of 20 patients with bilateral rolling and boxcar acne scars were enrolled. Subcision using microkeratomes was done followed by either peeling using 35% trichloroacetic acid on one side or microneedling on the other side. Evaluation of response was done by Echelle d'Evaluation clinique des Cicatrices d'acné grading scale and optical coherence tomography imaging.

Results
Both therapeutic modalities yielded statistically significant improvement of acne scars and statistically significant decrease in acne scar depth. There was neither a statistically significant difference between the two sides regarding Echelle d'Evaluation clinique des Cicatrices d'acné scoring after treatment (P=0.968) nor regarding optical coherence tomography acne scar depth after treatment (P=0.583).

Conclusion
This novel technique of subcision is a safe and effective method for rolling and boxcar scar treatment, with almost no adverse effects and no downtime. In addition, trichloroacetic acid 35% peel is cheaper, as well as does not need any extensive special training or expensive instruments, as compared with microneedling, but microneedling shows better skin tightness and improvement of skin elastolysis especially in older patients.
Serum interleukin 15 as a marker of activity in patients with vitiligo
Authors: Hamza Ashraf , Aiad Mona , Abdel-Bary Ahmed , Gouda Eman 
Published: June 2021

Background
Interleukin 15 (IL15) is a proinflammatory cytokine that is involved in the pathogenesis of several autoimmune and inflammatory diseases. The stability of vitiligo represents the periods of no activity of the disease, and it is crucial in determining the line of treatment of the patient.

Objective
To assess serum IL15 in patients with vitiligo and to evaluate its predictive capacity as a marker of vitiligo activity.

Patients and methods
A total of 40 patients with nonsegmental vitiligo were included, in addition to 30 age-matched and sex-matched healthy individuals as a control. The severity of vitiligo was assessed using vitiligo area severity index score, whereas the activity of disease in patients was assessed using vitiligo disease activity score. Serum levels of IL15 were measured using the ELISA technique.

Results
The mean serum level of IL15 was significantly higher in patients with vitiligo (201.14±115.41 ng/l) than in control (136.13±22.57 ng/l). Moreover, the mean serum level of IL15 was significantly higher in patients with unstable/active vitiligo (243.12±136.64 ng/l) than in patients with stable vitiligo (144.35±28.82 ng/l). Patients with serum level of less than or equal to 150.90 ng/l can be diagnosed as stable vitiligo, with 76.47% sensitivity and 73.91% specificity.

Conclusion
IL15 is a good and reliable marker for the detection of activity in patients with vitiligo, but further studies are needed to follow the progression of disease and to correlate this with the serum level of IL15. Targeting IL15 could be a novel treatment approach for patients with vitiligo.

ABSTRACT.
Data on the longevity of humoral and cell-mediated immune responses against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in patients with coronavirus disease 2019 (COVID-19) are limited. We evaluated the detailed kinetics of antibody and T-cell responses at the acute, convalescent, and post-convalescent phases in COVID-19 patients with a wide range of severity. We enrolled patients with COVID-19 prospectively from four hospitals and one community treatment center between February 2020 and January 2021. symptom severity was classified as mild, moderate, or severe/critical. Patient blood samples were collected at 1 week (acute), 1 month (convalescent), and 2 months after symptom onset (post-convalescent). Human SARS-CoV-2 IgG and IgM antibodies were measured using in-house-developed ELISA. The SARS-CoV-2-specific T-cell responses against overlapping peptides of spike proteins and nucleoprotein were measured by interferon-γ enzyme-linked immunospot assays. Twenty-five COVID-19 patients were analyzed (mild, n = 5; moderate, n = 9; severe/critical, n = 11). IgM and IgG antibody responses peaked at 1 month after symptom onset and decreased at 2 months. IgG response levels were significantly greater in the severe/critical group compared with other groups. Interferon-γ-producing T-cell responses increased between 1 week and 1 month after symptom onset, and had a trend toward decreasing at 2 months, but did not show significant differences according to severity. Our data indicate that SARS-CoV-2-specific antibody responses were greater in those with severe symptoms and waned after reaching a peak around 1 month after symptom onset. However, SARS-CoV-2-specific T-cell responses were not significantly different according to symptom severity, and decreased slowly during the post-convalescent phase.

Livestock plays a significant role in the economy of a nation but its productivity can be hampered by numerous haemoparasites thereby leading to economic losses to the livestock industry. The prevalence of haemoparasite in cattle slaughtered at Jalingo abattoir was investigated. A total of four hundred blood samples were collected at the point of slaughter, processed, and screened for haemoparasites by examining Giemsa-stained thin blood smears. An overall prevalence of 12.25% was recorded. Four haemoparasites of cattle with prevalence rates of 5.0%, 6.75%, 0.25%, and 0.25% for Anaplasma, Babesia, Microfilaria and Trypanosoma respectively were observed. The prevalence of haemoparasite in relation to sex, revealed higher infection in females (13.75%) than in males (10.0%) which were not found statistically different (P > 0.05). All breeds encountered during the study were infected with haemoparasites with the highest prevalence of 13.91 % recorded in White Fulani, Red Bororo (10.94%), and Sokoto Gudali (10.00 %), while Adamawa Gudali had the least prevalence of 0.5%. There was no statistically significant difference in the prevalence of haemoparasite in relation to breeds (P > 0.05). High prevalence was observed in the young (14.29%) more than the adult (11.59%) and older (12.14%). The current study has revealed the haemoparasites status in cattle slaughtered at Jalingo abattoir. Therefore, there is a need for effective preventive and control policy of these haemoparasites to enhance livestock productivity.
