Background: Parkinson’s disease (PD) is a complex, multifactorial neurodegenerative disorder with a pathophysiology deriving from the synergy of abnormal aggregation of neuroinflammation, synuclein and dysfunction of lysosomes, mitochondria and synaptic transport difficulties influenced by genetic and idiopathic factors. Worldwide, PD has a prevalence of 2-3% in people over the age of 65. To date, there is no certified, effective treatment for PD. Aim: The aims of this research were: (i) to present, on the basis of recent advances in molecular genetics and epigenetics, the genomic aspects and challenges of gene therapy trials for PD;(ii) to outline the ethical principles applicable to therapeutic trials for PD. Method: A systematic literature review was carried out to identify relevant articles reporting on genomic aspects and gene therapy in PD from 2001 to October 2023. The search was conducted in French and/or English in three databases: PubMed, Google Scholar and Science Direct. PRISMA guidelines were used in this systematic review. Results: A total of thirty-three publications were selected. An inductive thematic analysis revealed that numerous genetic mutations (SNCA, Parkin, PINK1, DJ-1, LRRK2, ATP13A2, VPS35, Parkin/PRKN, PINK1, DJ1/PARK7) and epigenetic events such as the action of certain miRNAs (miR-7, miR-153, miR-133b, miR-124, miR-137) are responsible for the onset of PD, and that genetic therapy for this pathology raises ethical questions that need to be elucidated in the light of the bioethical principles of autonomy, beneficence, non-maleficence and justice. Conclusion: There is no zero risk in biotechnology. Then, it will be necessary to assess all the potential risks of Parkinson disease’s gene therapy to make the right decision. It is therefore essential to pursue research and, with the guidance of ethics, to advance treatment options and meet the challenges of brain manipulation and its impact on human identity. The golden rule of medicine remai

Objective: The main objective was to study the disturbances of the Blood Count of children hospitalized in the general pediatric of the Gabriel Touré teaching hospital. Methods: This was a prospective and descriptive study conducted from September 1 to November 30, 2018 in the general pediatrics department of the Gabriel Touré teaching hospital in Bamako. Data were collected on patient records using a survey sheet. Results: We collected 512 files of children out of 1030 admissions during the study period;the rate of completion of the blood count is 50%. The male sex was predominant with a sex ratio of 1.3. The majority of patients were under 5 years old (58%). The majority of fathers (56%) and mothers (64%) of children had no education;they are mainly farmers (61%) and housewives (88%). Pallor was the reason for consultation in 29% of patients and present in 60%. On blood count, anemia was present in 92% of patients, half of whom (50%) had severe anemia with a hemoglobin level below 7 g/dL. The anemia was mainly microcytic (72%) and hypochromic (66%). Hyperleukocytosis (62%), eosinophilia (68%) and basophilia (58%) were the abnormalities observed in the white line. Thrombocytopenia accounted for 40%. Severe malaria (53%) was the main discharge diagnosis and almost all patients (99%) were alive at discharge. Conclusion: The characteristics of anemia require a study of the complete blood count in healthy children with dosage of serum iron and ferritin for a better understanding of the phenomenon.

Human papillomavirus (HPV) is classified into high-risk HPV (HR-HPV) and HPV (LR-HPV) according to their oncogenic potential. These viruses can be found in the cervix, vagina, vulva, anus and in the ENT sphere. HPV ENT infections can lead to benign or malignant tumors in which we could find both LR-HPV and HR-HPV genotypes. The objective of this study was to investigate the genotypes of HR-HPV and LR-HPV in archived tissue samples derived from both benign and malignant tumors of the ear, nose, and throat (ENT) in Ouagadougou, Burkina Faso. One hundred and twenty formalin-fixed, paraffin-embedded archived tissues of the ENT sphere from 26 benign tumors and 94 malignant tumors were included. The tissues were first deparaffinized with xylem. The extracted DNA was used to test for high-risk and low-risk HPV by Real-Time Multiplex PCR. HPV DNA was found in 57.7% (15/26) of benign tumors and 43.61% (41/94) of malignant tumors. The prevalence of HPV infection was 46.67% (56/120) in all tumors combined. The most common HPV genotypes found were HPV 11 (34.28%), HPV 6 (30%), HPV56 (14.28%) and HPV 33 (8.57%). There were 21.43% (12/56) cases of genotypes co-infections with 10 cases of double infection and 2 cases of triple infection. Both low-risk and high-risk HPV are found in ENT tumors with relatively high HPV prevalence.

Design and synthesis of organic chelating agents containing nitrogen and sulfur as donor atoms and their metal complexes is an interesting field of research for their different types of activities. The bi-dentate N,N chelating agent such as 2,2-Bipyridal has been playing a vital role in synthetic and medicinal chemistry. 2,2-Bipyridal has been used to prepare many mixed-ligand complexes. Different ligand complexes prepared from 2,2-Bipyridyl are used in different areas such as molecular catalysis, solar energy conversion, calorimetric analysis, herbicides, molecular recognition, self-assembly, antineoplastic agents, and nucleic acid probes. Another important property of these types of compounds is the triplet state photosensitizing character of bipyridyl nucleus, which is shown in metal complexes. It is also found that compounds containing O,S,N atoms have received considerable attention because of their pharmacological studies like anticancer, antibacterial, and antitumour activities. Therefore, it has been decided to synthesize Schiff bases derived from 2,2’- bipyridyl-5,5’-dicarbaldehyde compounds with O,S,N and F-containing amines and study their antibacterial properties. Several new Schiff bases have been synthesized and fully characterized by spectral data. This paper presents the synthesis and characterization of newly designed Schiff bases.
