The role of Zi2 during neural tube and neural crest development

Research Article of Global Journal of Molecular Biology The role of Zi2 during neural tube and neural crest development Gerald Muça* Department of Morfofunctional Modules, Faculty of Veterinary Medicine, Agricultural University of Tirana, Koder Kamez, 2021 Tirana-Albania The transcription factor Zic2 is member of Zic family, at early stages it has been involved in several processes during embryonic development and later on in morphogenesis and organogenesis. An important role has been attributed to Zic2 during the development of the neural system. It has been involved in neural tube and neural crest formation. Both process structures will form the central and peripheral neural system. Mutation of Zic2 provokes holoprosencephaly in humans and in mouse also spina bifida. To date, there is not well elaborated the specific mechanisms under which Zic2 affect neural tube formation and the differences may exist between mouse and human phenotype. Almost the same ambiguity is for the specific role of Zic2 during neural crest development. Here is given are resumed latest studies and are given new insight about the role of Zic2 in these two processes and its new target genes. Keywords: Zic2; neural tube; neural crest; cell proliferation; development ...

Hematological parameters and sorological detection of canine hemoparasitoses with SNAP 4DX

Research Article of Global Journal of Molecular Biology Hematological parameters and sorological detection of canine hemoparasitoses with SNAP 4DX Teixeira C.L1; Picanço K.R2; Silva F.J3; Alves A.J4; Souza Neto Júnior J.C5 1Zootechnist and Specialization in Clinical and Toxicology Analysis Student; 2Clinical and Toxicology Analysis Specialist; 3Specialization in Clinical and Toxicology Analysis Student - UFPE; 4Full Professor – UFPE; 5Doctor of Veterinary Medicine - UFRN Introduction: The SNAP 4Dx is a rapid test device that uses ELISA (Enzyme-Linked Immunosorbent Assay) technology manufactured by the IDEXX Laboratory (Maine, USA) for rapid diagnosis of hemoparasitosis in dogs. SNAP® ELISA technology utilizes unique conjugate and substrate that amplifies the results. The bidirectional flow process evidences the antigen-antibody binding, providing high sensitivity and reliable results. Objective: evaluation of hematological parameters and serological detection of hemoparasitoses in dogs with Snap 4Dx. Methodology: A cross - sectional, descriptive and observational clinical research was carried out between September 2014 and October 2014 at Pet Dream Veterinary Medical Clinic, located in the city of Recife / PE. The hemogram was performed using a manual technique using blood collected with EDTA. The detection of the antigen of Dirofilaria immitis and the antibodies of Anaplasma phagocytophilum, Anaplasma platys, Borrelia burgdorferi, Ehrlichia canis and Ehrlichia ewingii, was performed with SNAP 4DX Plus device. Results and Discussion: 62 dogs of different races were used, without specifying age or sex, attended at the Clinic. The blood samples were collected by venipuncture cephalic or jugular, according to the size of the animal. The samples were packed in eppendorf microtubes containing EDTA as anticoagulant. The differential count was performed through blood smearing, stained in panopticus, observed with a 100X immersion objective. The rapid test for serological diagnosis showed the following result: Ehrlichia canis (32.25%), Anaplasma platys (6.45%), Dirofilaria immitis (6.45%). Discussion: The results found in the ...

To evaluate the antimicrobial potential of Streptomyces spp. J181 against clinical isolates of S. pyogenes

Research Article of Global Journal of Molecular Biology To evaluate the antimicrobial potential of Streptomyces spp. J181 against clinical isolates of S. pyogenes Melo T.S1; Oliveira C.V.J2; Amaral J.P.D3; Lima G.M.S4; Sena K.X.F.R4 1Student of the Pharmacy Course, UFPE; 2Student of the Postgraduate Program in Biological Sciences, UFPE; 3Student of the Biomedicine Course, UFPE; 4Teacher/Researcher of the Department of Antibiotics, UFPE. Introduction: Streptomyces comprise the genus of actinobacteria most studied, as they have the ability to synthesize a variety of bioactive metabolites, of these many are antibiotics. Streptococcus pyogenes is a gram-positive coccus belonging to Group A of Lancefield. Among streptococci, it is the most relevant clinical agent in infections of the oral cavity due cases of streptococcal pharyngotonsillitis and its sequels: rheumatic fever and glomerulonephritis. They are also related to other pathologies such as endocarditis, septic arthritis, cellulitis, pyoderma and scarlatina. Objective: To evaluate the antimicrobial potential of Streptomyces spp. J181 against clinical isolates of S. pyogenes. Methodology: Blocks of 10 mm diameter obtained from the cultivation of the actinobacteria seeded on ISP-2 agar were transferred to Petri dishes containing 18 mL of blood agar previously seeded with S. pyogenes, then the plates were incubated at 35 ° C ± 1 ° C for 24 hours. After the incubation period, the inhibition halos were read in millimeters. To assess the susceptibility profile, the antibiogram of the bacterial isolates was carried out according to the recommendations of the Clinical & Laboratory Standards Institute. The tests were performed in triplicate, the results expressed in average plus standard deviation and the coefficient of variation adopted was ≤ 10%. Results and Discussion: The susceptibility profile of S. pyogenes isolates didn’t show resistance to the evaluated antibiotics, resulting in sensitivity to therapy commonly adopted in the medical clinic. The lineage of Streptomyces spp. J181 ...

Identification and susceptibility of the genus staphylococcus isolated from vegetables and legumes of economic interest

Research Article of Global Journal of Molecular Biology Identification and susceptibility of the genus staphylococcus isolated from vegetables and legumes of economic interest Amaral,J. P. D. l1; Ferreira Neto, J. P2; Magalhães, L. P. M. 3; Lima, C. S. A4; Yara, R. 4; Sena, K. X.F. R. 5 1Student of the Biomedicine Course, UFPE; 2 Student of the Morfotecnology postgraduate program, UFPE; 3Student of the postgraduate program in Pharmaceutical Sciences, UFPE; 4Teacher/Researcher of the Department of Biophysics, UFPE; 5Teacher/Researcher of the Department of Antibiotics, UFPE. Introduction: Microorganisms of Staphylococcus genus are Gram-positive cocci catalase-positive bacteria of clinical interest due to their pathogenicity in humans and animals. Staphylococcus aureus is part of the normal microbiota and can be responsible for suppurations of wounds, abscesses also it may transmit a toxinfection caused by the intake of toxins elaborated by the infectious agent present in foods. Objectives: Isolation and identification of Staphylococcus in products of economic interest cultivated in Pernambuco. Material and Methods: 25 g of the samples (cassava, carrot, coriander and cabbage) were added in 225 mL of 0.1% peptone saline, serial dilutions until 10-3 were made. The dilutions of 10-2 and 10-3 were seeded in Baird Parker medium and the colonies characteristic of the genus Staphylococcus were identified by the catalase, Gram, coagulase, Carbohydrate (Glucose, Trehalose, Ramnose, Mannose, Maltose, Lactose, Xylose, Sucrose and Inositol) and disc test with Polymyxin and Novobiocin. In addition, the Antibiogram of the isolated colonies was performed using the antibiotics Erythromycin, Vancomycin, Clindamycin, Sulfamethoxazole, Oxacillin, Chloramphenicol, Gentamicin and Ciprofloxacin. Results and Discussion: Eight colonies were isolated: cassava (1), coriander (1), carrot (1) and cabbage (5) and submitted to identification tests. Staphylococcus pasteuri, S. saprophyticus, S. warneri (3), S. hominis subsp. hominis and two classified as coagulase negative Staphylococcus. In the antibiogram 50% of the isolates presented resistance ...
