Multiplex PCR for Identification and Detection of Cassava Mosaic Begomoviruses in Togo

Cassava mosaic disease (CMD) caused by Cassava Mosaic Begomoviruses (CMBs) is one of the most devastating crop diseases and a major constraint for cassava production. In order to ensure surveillance for epidemic prevention, low-cost diagnostic tools are appropriate for large-scale testing of cassava viruses. Multiplex PCR diagnosis is one approach that can reduce diagnostic costs and delays. A multiplex PCR approach was developed for simultaneous detection of African cassava mosaic virus (ACMV), East African Cassava Mosaic Virus and East African cassava mosaic Cameroon virus (EACMV/CM) in Togo CMD-infected cassava leaves. Three primers pairs were used to target their respective viruses in a single tube PCR. Multiplex PCR detected ACMV, EACMV and EACMV/CM in plant DNA extracts prepared from cassava leaves infected with CMB. The primers amplified 783 bp specific to ACMV, 650 bp specific to EACMV and 560 bp specific to EACMCV/CM in both uniplex and multiplex formats. Multiplex PCR is an excellent tool for the effective control of cassava diseases. .

Contribution of High Sensible C-Reactive Protein (hsCRP) in the Assessment of the Risk of Onset of Type 2 Diabetes and Its Cardiovascular Complications

Background: Type 2 diabetes is a metabolic disease characterized by chronic hyperglycemia. The latter plays an essential role in inflammation by stimulating the production of pro-inflammatory cytokines or by increasing their secretion by an oxidative mechanism. These cytokines control the hepatic synthesis of an inflammatory protein called C-Reactive Protein (CRP). High or average values of CRP would have a predictive value of cardiovascular diseases and type 2 diabetes. The relationship between low CRP values and the risk of developing type 2 diabetes and its cardiovascular complications is not sufficiently studied. The hsCRP could serve as a predictive biomarker of risk of onset, follow-up and prognosis for type 2 diabetes and its cardiovascular complications. To answer this problem, we conducted this study, the aim of which was to study the predictive role of hsCRP in the risk of occurrence of type 2 diabetes and its cardiovascular complications. Materials and Methods: This is a prospective and cross-sectional case-control study involving 200 participants including 100 control women and 100 women with type 2 diabetes (mean age was respectively 49.89 years ± 8.26 & 51.92 years ± 7.18;p = 0.066). The interviews were conducted on the basis of a questionnaire. Physical examination collected biometric data and cardiovascular constants. The biochemical parameters such as hsCRP were analyzed by an automated Abbott device. Results: We noted that hsCRP was significantly higher in type 2 diabetic subjects compared to control subjects (p (rho = 0.40, p systolic blood pressure (rho = 0.30, p = 0.003), diastolic blood pressure (rho = 0.28, p = 0.006), total body fat (rho = 0.48, p Conclusion: hsCRP has a prognostic value in the evaluation of cardiovascular risk. It seems to play an important role in the pathogenesis of type 2 diabetes mellitus and its cardiovascular complications. It could thus be considered as a biomarker for the screening, monitoring and prognosis of type 2 diabetes mellitus.

East African Cassava Mosaic Virus and East African Cassava Mosaic Cameroon Virus: Two Species Emerging in Togo

Cassava mosaic disease (CMD) caused by the whitefly-transmitted Begomoviruses (family Geminiviridae) is a major threat to production of cassava (Manihot esculenta Crantz) in Togo. Survey was conducted in 2020 in the 5 agroecological zones of Togo to assess the status of East African cassava mosaic virus (EACMV), East African cassava mosaic Cameroon virus (EACMCMV) and its distribution. Polymerase chain reaction (PCR) and Sanger sequencing were used for the detection of cassava mosaic Begomoviruses (CMBs) in the sampled leaves. The incidence of EACMV was 47.93% (278/580) and varied between 41.30% (Zone V) and 62.29% (Zone IV) across the agroecological zone but no significant difference was observed. The EACMCMV incidence was 13.67% (38/278) and varied significantly (p ≤ 0.001) through the agroecological zone. Phylogenetic analysis of the viral isolates showed that they are closely related to those from Nigeria, Ghana, and Ivory coast. Nucleotide sequence analysis of CP revealed an overall genetic diversity (π) of around 3.4%. These results showed that EACMV was the predominant virus and that EACMCMV incidence could be more widespread in Togo.

A particular attention is paid to buffer pH shown to be tissue dependent. With this inexpensive microplate method, it is possible to analyze 12 experimental samples in about 45 min all in triplicates, with blanks, controls and standard curve.

Phytochemical Study and Evaluation of Cytotoxicity, Antioxidant and Hypolipidemic Properties of <i>Launaea taraxacifolia</i>Leaves Extracts on Cell Lines HepG2 and PLB985

Launaea taraxacifolia is a leafy vegetable of the family of Asteraceae (Compositae) found in several countries in West Africa including Ghana, Benin and Nigeria. The plant leaves are eaten either fresh as salad or cooked as sauces. They are also consumed as infusion to fight against several diseases including non-communicable diseases such as diabetes and hypertension. Several studies have been conducted in Ghana, Nigeria on the nutritional and medicinal values of this plant but no study has yet been conducted in Benin on the virtues of this plant. In this work we have achieved the phytochemical characterization and evaluated the cytotoxicity as well as hypolipidemic and anti-oxidant effects of the ethanol-aqueous extracts of Launaea taraxacifolia leaves. Cytotoxicity and hypolipidemic activities have been performed on HepG2 cells;the antioxidant effect has been performed on the PLB985 cells. The results showed that the ethanol-aqueous extracts of Launaea taraxacifolia leaves contained the following metabolites: catechic tannin, flavonoids, phenolic acids, mucilage and leucoanthocyanins. Only very high concentrations (>20 mg/ml) of leaves extracts are toxic for HepG2 cells. Launaea taraxacifolia leaves have significant antioxidant and hypolipidemic activities.

Purification and characterization of glyceraldehyde-3-phosphate dehydrogenase from saline strain Idiomarina loihiensis

Idiomarina loihiensis was isolated from the salt works in Sfax (Tunisia), until now, the characterization of the GAPDH phosphorylante was never studied. Here, we report the isolation and the biochemical characterization of glyceralehyde-3-phosphate dehydrogenase (GAPDH) fromI. loihiensis saline’s bacteria on the basis of the apparent native and subunit molecular weights, physico-chemical and kinetic characterizations. The purification method consisted of two steps, ammonium sulfate fractionation followed by one chromatographic step, namely dye-affinity on Blue Sepharose CL-6B. Polyclonal antibodies against the purified enzyme were used to recognize theI. loihiensis GAPDH by Western blotting. The optimum pH of the purified enzyme was 8.5. Studies on the effect of temperatures revealed an enzyme increasing activity of about 45?C. The molecular weight of the purified enzyme was 36 kDa determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Non-denaturing polyacrylamide gels yield a molecular weight of 147 kDa. The Michaelis constants for NAD+ and D-glyceraldehyde-3-phosphate estimated was 19 μM and 3.1 μM, respectively. The maximal velocity of the purified enzyme was estimated to be 2.06 U/mg, approximately 6-fold increase in specific activity and a final yield of approximately 32.5%. The physicochemical properties of this GAPDH, being characterized, could be used in further studies.

Antioxidant capacity and genoprotective effect of ethanol fruit extract from Detarium microcarpum Guill. and Perr.(Caesalpiniaceae)

Objective: To evidence the ability of ethanol fruit extract from Detarium microcarpum(D. microcarpum) to preserve DNA integrity against oxidative genomic damage.Methods: Ethanol extract from D. microcarpum fruit pulp was analyzed for its antioxidant capacity using ferric reducing antioxidant power, 2,2-diphenyl-1-picrylhydrazyl,2,20-azinobis-3-ethyl-ethylbenzothiazoline-6-sulphonate, superoxide anion, deoxyribose degradation and lipid peroxidation models. The genoprotective activity was assessed ex vivo by comet assay, on liver cells of NMRI female mice using cyclophosphamide(CP) as genotoxic agent.Results: Ethanol extract from D. microcarpum fruit pulp exhibited interesting antioxidant activity in 2,2-diphenyl-1-picrylhydrazyl, deoxyribose degradation and lipid peroxidation assays. The extract did not present any genotoxic effect but protected DNA against CP-induced damages with a dose-dependent manner. The genoprotective effect observed was related to the antioxidant molecules of the fruit that scavenged the hydroxyl radical(generated by the metabolism of CP) as well as the peroxyl and alkoxyl radicals issued from lipid peroxidation. Other mechanisms such as inactivation of CP metabolism to genotoxic end products, induction of the expression of antioxidant and DNA repair enzymes have been discussed.Conclusions: Our results suggest that the wild edible fruit from D. microcarpum could be beneficial on consumer's health by its antioxidant and genoprotective effects, particularly during chemotherapies exhibiting genotoxic effects like CP in cancer treatment.

Towards a tailored indoor horticulture:a functional genomics guided phenotypic approach

As indoor horticulture gathers momentum,electric(also termed artificial)lighting systems with the ability to generate specific and tunable wavelengths have been developed and applied.While the effects of light quality on plant growth and development have been studied,authoritative and reliable sets of light formulae tailored for the cultivation of economically important plants and plant traits are lacking as light qualities employed across laboratories are inconsistent.This is due,at least in part,to the lack of molecular data for plants examined under electric lights in indoor environments.It has hampered progress in the field of indoor horticulture,in particular,the transition from small-scale indoor farming to commercial plant factories.Here,we review the effects of light quality on model and crop plants studied from a physiological,physical and biochemical perspective,and explain how functional genomics can be employed in tandem to generate a wealth of molecular data specific for plants cultivated under indoor lighting.We also review the current state of lighting technologies in indoor horticulture specifically discussing how recent narrow-bandwidth lighting technologies can be tailored to cultivate economically valuable plant species and traits.Knowledge gained from a complementary phenotypic and functional genomics approach can be harvested not only for economical gains but also for sustainable food production.We believe that this review serves as a platform that guides future light-related plant research.

Study of glyceraldehyde-3-phosphate dehydrogenase expression in the tumor process of: Breast, cervix and prostate cancers

W Tumor proliferation of cancer cells requires a high intake of oxygen by angiogenesis. Deep cancer cells suffer from asphyxia and meet their energy needs through the enzymes of glycolysis. The anti-angio- genesis approach has been recognized for therapeutic purposes, but the deep cancers, difficult to reach by this therapy, could be targeted by inhibiting an enzyme of the glycolytic cycle. Our work focused on the study of the expression of GAPDH, a key enzyme of glycolysis, in cervix, breast and prostate tumors, for two approaches: Fundamental and targeted therapeutics. 60 samples, taken at the Anatomopathology laboratory of the Pasteur Institute of Morocco, were examined histologically and immunohistochemically, demonstrating the expression and cellular localization of GAPDH. The three organs have shown an overex-pression of GAPDH in tumor tissues. At the cellular level, the localization of GAPDH in cancer tissue is diffuse but mostly nuclear whereas it remains focused at the membrane and/or the cytoplasm in benign tumor tissues. From these results we could assume that GAPDH is involved in the cancer process and draws attention to a possible new nuclear role that could be either specific to one form or different isoforms of GAPDH enzyme.

Young footballers, assessed by deep breathing test, have a higher vagal response

Parasympathetic function can be assessed by the deep breathing test (DB) as a simple and reproducible cardiovascular reflex. The aim of this study is to use this test to compare the vagal response of a young footballers group to of age-matched untrained normal subjects. Deep breathing test was performed in 2 groups: one of 20 adult young footballers (average age of 19.3 ± 0.6 years), and a second age-matched group of 20 untrained subjects (average age of 19.6 ± 0.6 years). Subjects underwent the DB test after 30 min resting in supine position, and responses were expressed as a percentage of variation of heart rate during the stimulation. Student’s t-test was used to evaluate statistical differences among the two groups for all parameters (vagal response, heart rate, VO2max….) and considering p < 0.05 as a significant difference. The results showed that vagal response to deep breathing test was significantly higher in the young footballers when compared to the untrained controls (72.6% ± 16.2% vs 55.0% ± 12.8%, respectively, p = 0.03). The basal heart rate was significantly lower in footballers than in the controls group (52.1 ± 7.4 bat/min vs 69.8 ± 14.3 bat/min, p < 0.01). The use of the simple test of deep breathing allowed us to demonstrate that adult young footballers have a significantly lower basal HR and higher parasympathetic response in comparison to untrained subjects.

Antioxidant Activity and Phenolic Compounds Content of Extracts from Ceratotheca sesamoides Endl and Striga hermonthica (Delille) Benth Used as Antheminthic in Burkina Faso

The revaluation of medicinal plants in the veterinary pharmacopoeia is essential for the development of livestock in Burkina Faso. In order to justify the use of C. sesamoides and S. hermonthica in the treatment of gastrointestinal parasitosis of small ruminants, a quantification of phenolic compounds as well as antioxidant activity and acute toxicité evaluation of both plants were performed. Acute toxicity was evaluated by administering a single dose of 2000 mg/kg body weight of aqueous extract of both plants to mice. The highest total polyphenol content for C. sesamo?des was obtained in the ethyl acetate fraction with 47.236 ± 2.57 mgEAG/100mg while that of S. hermonthica was 74.871 ± 2.57 mgEAG/100mg obtained with the n-butanol Fraction. The dichloromethane extract of S. hermonthica obtained the highest total flavonoid content with 7.31 ± 0.48 mgEQ/100 while the highest total flavonoid content of C. sesamo?des was obtained with ethyl acetate fraction with 5.4273 ± 0.35 mgEQ/100mg. The aqueous extract of C. sesamo?des obtained the highest content of condensed tannins with 3.028 ± 0.13 mgEAT/100mg. Both plant’s extracts did not show any signs of toxicity in NMRI mice after administration of the dose of 2000 mg/kg. The antioxidant activity by DPPH, FRAP and ABTS methods was good compared to those of Quercetin and Trolox taken as standard.

Effect of Herbicides Used in Horticulture (2,4-D, Glyphosate and Nicosulfuron) on Snails <i>Achatina fulica</i>(Bowdich, 1720)

2,4-Dichlorophenoxyacetic (2,4-D), glyphosate, and nicosulfuron, because of their modes of action and selectivity, are the most widely used herbicides in Ivorian horticulture. Fuels toxicity was the reason of many debates in the world because of their massive and uncontrolled use. They are frequently blamed for the reduction of soil fertility and terrestrial biodiversity observed in agricultural areas. In view of the debates raised by their toxicities, the use of these herbicides requires the greatest caution and clear information on the real risk incurred by the edaphic fauna by conducting ecotoxicity studies. The present study aims to evaluate the effect of 2,4-D, glyphosate and nicosulfuron herbicides on the growth and reproduction of Achatina fulica snails in microcosm. To do this, we treated each plot on which snail microcosms were placed with 2,4-D, glyphosate or nicosulfuron herbicides according to the manufacturer’s recommendations. The results showed for all the herbicides used, that after 28 days of exposure, the growth of juvenile snails was slowed down. The number of eggs laid per pair was reduced in adult snails. The egg hatchability test revealed a reduction in egg hatchability. In addition, each effect was dependent on the herbicide used. Thus, toxicity was found to be greater according to the following order: nicosulfuron ? glyphosate ? 2,4-D. From the results obtained, we concluded that 2,4-D, glyphosate, and nicosulfuron treatments under field conditions are a potential threat to the sustainability of snail species and therefore to soil life. The intensity of the effect depends on the toxicity of the herbicides used.

Effects of Sarcocephalus latifolius Fruits Extract on Paracetamol-Induced Liver Damage in Wistar Rats

Background and Aim: Sarcocephalus latifolius is a medicinal plant commonly used in traditional medicine to treat various diseases. The aim of the present study is to evaluate the hepatoprotective activity of Sarcocephalus latifolius fruits aqueous extract against paracetamol-induced liver damage in rats. Material and Methods: Aqueous extract of Sarcocephalus latifolius fruits at doses of 100, 250 and 500 mg/kg were administered orally to rats with paracetamol-induced hepatotoxicity (1 g/kg). The treatment with the extract and paracetamol lasted 7 days. Silymarin (50 mg/kg) was given as reference control. All tested drugs were administered orally. Results: Our results show that the Sarcocephalus latifolius fruits extract induced a significant reduction (p < 0.05) of serum enzymes alanine aminotransferase (ALAT), aspartate aminotransferase (ASAT), alkaline phosphatase (PAL) and total bilirubin (TB). Then, the extract at the dose of 500 mg/kg showed a better protection (p < 0.001) of hepatocytes with a percentage of protection of 43.59% ± 2.03%;59.43% ± 4.12%;73.29% ± 5.72% and 62.55% ± 7.48% for ALAT, ASAT, PAL and TB, respectively. The histology of livers exposed to paracetamol shows an inflammation of the hepatocytes. In addition, there was a significant alteration of the liver parenchyma. The 500 mg/kg extract showed a resorption of the inflammation. Histopathological examination showed that the extract regenerated paracetamol-induced liver damage. Conclusion: Aqueous extract of Sarcocephalus latifolius fruits has hepatoprotective activity against paracetamol-induced hepatotoxicity in rats. But it would be important to evaluate the activity of aqueous extract of Sarcocephalus latifolius fruits on oxidative stress parameters in vivo in rats. .

Colistin Resistance Profiles, Molecular Investigation of mcr-1 and mcr-2 Plasmid Genes and Investigation of Carbapenemase Production in Pseudomonas and Acinetobacter Strains

Background and Purpose: The reintroduction of colistin as a last resort treatment against multi-resistant Gram-negative bacilli, is currently challenged by the emergence of colistin-resistant bacteria. The aim of this study was to assess the susceptibility of Pseudomonas and Acinetobacter strains to colistin, to identify carbapenemase production, and to investigate the plasmid genes involved in colistin resistance and carbapenemase production. Methodology: In order to establish the susceptibility profiles of 17 strains of Pseudomonas and Acinetobacter to colistin, their Minimum Inhibitory Concentrations (MICs) were determined using the liquid microdilution method. The possible production of carbapenemases was investigated with the modified Carbapenem Inactivation Method (mCIM). The search for genes encoding carbapenemases (blaOXA, blaIMP, blaCarba) and those responsible for plasmid resistance to colistin (mcr-1 and mcr-2) was performed by conventional PCR. Results and Conclusion: Ninety-four percent (94%) (16/17) of the strains were resistant to colistin. Intraspecies distribution was 50% (8/16), 31% (5/16), 13% (2/16) and 6% (1/16) for Acinetobacter baumannii, Pseudomonas aeruginosa, Pseudomonas luteola, and Pseudomonas fluorescens, respectively. Twenty-nine percent (29%) (6/17) of the strains produced carbapenemases. No mcr-1 and mcr-2 plasmid genes were detected. On the other hand, 17.6% (3/17) of the strains possessed the carbapenemase genes distributed as follows: Carba type (60%), OXA type (40%) and IMP type (0%). The results of this study highlight a high resistance to colistin in strains belonging to the genera Acinetobacter and Pseudomonas, and some of these strains produce carbapenemases.

Roles of the Apolipoprotein E Gene and Its Polymorphisms in the Etiopathophysiology of Type 2 Diabetes Mellitus and Its Atherosclerotic Complication in Senegalese Females

Lipid metabolism disorders would be among the components responsible for the risk of the onset of T2DM and its vascular complications. Apolipoprotein E plays an important role in lipid metabolism. We studied the involvement of the APOE gene in the onset of T2DM and its vascular complications. Clinical and biochemical parameters were assessed in each participant. APOE genotypes were identified by PCR-RFLP. Arterial stiffness was studied using a pOpmetre® which evaluates the pulse wave velocity (ft-PWV). Endothelial dysfunction was studied using an EndoPAT2000® which measures endothelium-dependent vasodilation (RHI). In control subjects, the ε3 allele was associated with an increase in fasting blood glucose (r = 2.36, p = 0.018), and a decrease in LDL cholesterol levels (r = −2.17, p = 0.03), and ε4 was associated with an increase in total cholesterol (r = 2.59, p = 0.01), LDL cholesterol (r = 2.84, p = 0.004), and No-HDL cholesterol (r = 2.74, p = 0.006). In type 2 diabetes subjects, the ε2 was associated with a decrease in diastolic blood pressure (r = −2.25, p = 0.02). The ε3 was associated with a decrease in ft-PWV (r = −2.26, p = 0.024) while the ε4 was associated with an increase in ft-PWV (r = 2.52, p = 0.012). Carrying the ε2ε3 genotype would have in 99% a limited risk of developing T2DM, and in event of T2DM, only 1 to 2% would have a significant risk of developing atherosclerosis, which would be severe in 17%. Of the ε2ε4 genotype, 93% had a limited or even possible risk of developing T2DM, the remaining 7% had a very high risk of developing T2DM. Diabetics carrying ε2ε4 had in 7% very high risk of developing atherosclerosis. The latter had a 20% very high risk of being very severe. Subjects carrying the ε3ε4 genotype had a 67% possible or even probable risk of developing T2DM and in the event of diabetes, there was in 34% very high risk of developing atherosclerosis which will not have even the time to evolve towards severity. For subjects carrying the ε3ε3, the risk of developing T2DM and athérosclerosis was higher than that of the ε2ε3, and ε2ε4 genotypes but lower than that ε3ε4 genotype. The physio-pathological role of the APOE gene and the impacts of its polymorphisms are important in the onset and progression of type 2 diabetes mellitus.

Evaluation of androgenic activity of Zingiber officinale and Pentadiplandra brazzeana in male rats

Aim: Aqueous extracts of Zingiber officinale and Pentadiplandra brazzeana were tested for their possible androgenic activity in male Wistar rats. Methods: The aqueous extracts of the two plants were gavaged separately to 2 groups of rats at a similar dose of 600 mg.kg^1.day-1 for 8 days. At the end of the treatment, the animals were killed and the blood, testis, epididymis, seminal vesicles and prostate were collected for biochemical analysis. Results: The aqueous extract of Z. officinale significantly increased in the relative weight of the testis, the serum testosterone level, testicular cholesterol level and epididymal α-glucosidase activity. The aqueous extract of P. brazzeana significantly increased the weights of the testis, seminal vesicles and prostate. It also significantly increased the serum and testicular testosterone level. The fructose, α-glucosidase and cholesterol levels in P. brazzeanatreated rats were increased by 28%, 35% and 114%, respectively. Conclusion: The aqueous extracts of both P. brazzeana and Z. officinale have an androgenic activity, which seems to be more potent with P. brazzeana than with Z. officinale.

New tools for optimizing fluid resuscitation in acute pancreatitis

Acute pancreatitis(AP)is a frequent disease with degrees of increasing severity responsible for high morbidity.Despite continuous improvement in care,mortality remains significant.Because hypovolemia,together with microcirculatory dysfunction lead to poor outcome,fluid therapy remains a cornerstone of the supportive treatment.However,poor clinical evidence actually support the aggressive fluid therapy recommended in recent guidelines since available data are controversial.Fluid management remains unclear and leads to current heterogeneous practice.Different strategies may help to improve fluid resuscitation in AP.On one hand,integration of fluid therapy in a global hemodynamic resuscitation has been demonstrated to improve outcomein surgical or septic patients.Tailored fluid administration after early identification of patients with high-risk of poor outcome presenting inadequate tissue oxygenation is a major part of this strategy.On the other hand,new decision parameters have been developed recently to improve safety and efficiency of fluid therapy in critically ill patients.In this review,we propose a personalized strategy integrating these new concepts in the early fluid management of AP.This new approach paves the way to a wide range of clinical studies in the field of AP.
