Bioactivity of Plant Extracts Against Fusarium Oxysporum f. sp. Lycopersici Sacc.) Causing Wilt Disease of Tomato (Solanum Lycopersicum L) in the Southern Guinea Savannah, Nigeria

Wilt disease of tomato is caused by Fusarium oxysporum f. sp. lycopersici and it is an important disease which causes significant yield reduction in the crop throughout the world. A study was undertaken to isolate, identify and test the pathogenicity of F. oxysporum f. sp. Lycopersici on tomato; and to evaluate the bioactivity of Azadirachta indica leaf, Piper guineense seed and Zingiber officinale rhizome extracts as well as the synthetic fungicide, mancozeb at different concentrations and combinations for the management of F. oxysporum f. sp. lycopersici in vitro. Results revealed that the percentage frequency of the fungus isolated and identified was more on the roots (35.56 %) than the stems (26.67 %), fruits (20.00 %) and leaves (17.77 %). Results of the pathogenicity test showed more virulence in the roots than in other parts of the tomato plant. Extracts of the three plants and mancozeb proved effective in controlling the mycelial growth of the fungus either alone or when combined. Mancozeb consistently gave 100 % growth inhibition irrespective of the concentration used. Among the plant extracts applied alone at 40 g/L, Z. officinale (66.69 %) was the most effective followed by P. guineense (53.52 %) while A. indica was the least (36.99 %). The mycelial growth inhibition increased from 40 g/L to 120 g/L irrespective of the combination of the treatments used. A combination of mancozeb with any plant extract was more effective than a combination of the plant extracts. It is therefore, recommended that the plant extracts be applied either alone or in combination with other plant extracts or the fungicide to control F. oxysporum f. sp. lycopersici, increase tomato yield and reduce postharvest rots associated with the pathogen

Unveiling Natures Arsenal: Harnessing Entada africana's Methanol Bark Extract to Combat Malarial infection Through Heme Polymerase Inhibition

Plasmodium parasites, which cause malaria, continue to pose a serious threat to global health, necessitating the continuous search for novel antimalarial agents. Entada africana is a plant known for its ethnomedicinal uses in treating various ailments associated with inflammation including malaria. Due to its reported antiplasmodial potentials, we studied the effect of the methanol bark extract of the plant. HPLC chromatogram of the methanol bark extract showed the presence of eight phyto-compounds namely coumaric acid, gallic acid, catechin, ferulic acid, quercetin, apigenin, rutin, and kaemferol. Thus, the study aimed at evaluating the antiplasmodial potential of methanol bark extract of Entada africana (MBEEA) through heme polymerase inhibition via in silico approaches. The in silico studies showed favourable binding affinities and stable interactions with heme polymerase, with rutin (-9.9 kcal/mol), apigenin (-8.0 kcal/mol) and catechin (-7.8 kcal/mol) having higher binding affinities compared to the standard drug, chloroquine (-6.7 kcal/mol). Hydrogen bond analysis reveals that ferulic acid (Asp 77, Ile 73 and Ala 29) and kaemferol (Arg 40, Arg 27 and Leu 74) form three hydrogen bonds. On the other hand, compounds like coumaric acid (Ala 291 and Arg 27), gallic acid (Ala 29 and Ser 76), catechin (Arg 40 and Arg 40), and quercetin (Ser 76 and Ser 76) form two hydrogen bonds with the amino acid residues, rutin forms two hydrogen bonds with Ser 76 and Leu 74, while apigenin forms one hydrogen bond with Arg 27 when compared to the standard drug, chloroquine (-6.7 kcal/mol) which forms no hydrogen bonds with the amino acid residues. Based on their pharmacokinetic characteristics, safety profiles, and appropriate drug-like ability, seven compounds were shown to have antiplasmodial properties by computational ADMET tests

Approach to and Management of a Adynamic Bone Disease in Hemodialysis Patients-A Review

Chronic kidney disease (CKD) is now a global public health epidemic with increasing rates reported all over the world. Currently, more than 850 million people are estimated to live with CKD worldwide. Bone and mineral disorders (CKD-MBD) form an integral part of the management of CKD patients. CKD-MBD encompasses distinct abnormal pathology within the spectrum of Renal Osteodystrophy (ROD), including osteitis fibrosa cystica, osteomalacia, adynamic bone disease (ABD), mixed lesions, and osteoporosis. ABD is primarily characterized by decreased or absent bone formations along with low cellularity of both osteoblasts and osteoclasts as well as thin osteoid seams and minimal or absent peri trabecular/marrow fibrosis. ADB is also associated with a greater risk of vascular calcification and fractures negatively affecting patient outcomes. It is unclear if all forms of ABD are truly pathological or milder forms of ADB could be a compensatory mechanism to guard against bone loss. In this article, we describe a hemodialysis patient profile of ADB with a review of this entity

Type1 Heavy-Tailed Mixture Cure Rate Survival Model Based on a Variant of T-X Family of Distribution as Baseline

In this research work, a new class of heavy-tailed mixture cure rate models; Type 1 Heavy-Tailed Gamma (T1HT-G) mixture cure rate model was introduced using a new class of heavy-tailed distributions; Type 1 Heavy-Tailed Gamma (T1HT-G) distribution as baseline. The maximum likelihood parameters estimation approach was adopted for estimating the model parameters. Also, the Monte Carlo simulation approach was adopted to assess the performance of the maximum likelihood parameter estimation. Deviance information criteria such as AIC, BIC and CAIC were adopted to measure the models’ performance. The simulation studies were conducted using three different sample sizes and 50 replications. Results from the model applications using real life biological and biomedical data. Comparative measures from the models TI-HTG mixture cure rate (AIC=51.60, BIC=61.55, CAIC=52.08) were smaller which showed the adequacy of the models to provide better fit for heavy-tailed data than the well-- known standard distributions. These results have supported the fact that heavy tailed models provide better fits than the usual standard distributions when analyzing heavy-tailed data.

Sound-Sensitive Molecules

Humanity has been wondering about the mechanisms of hearing for over 2,000 years. Many theories have been developed trying to solve this problem. The organ of hearing is still the only sense organ that is not fully understood. There is no doubt that the truth about hearing is different from the one proclaimed by the orthodox theory of hearing under the name of Bekesy's traveling wave. In order to change the seemingly erroneous status quo in explaining the mechanisms of hearing, I propose to start an analysis of all the circumstances that appeared after the announcement of the traveling wave theory. A new picture of hearing is emerging, significantly different from that described in textbooks and numerous publications. Censorship by orthodox reviewers can no longer inhibit new knowledge about hearing. This paper indicates the gaps in the current hearing theory and presents a new philosophy of hearing

Anodizing for Design and Function

Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.
