TL;DR: To the best of the knowledge, this is the first study in which an anti-cancer compound has been identified from the seeds of M. lanceolata and its anti-tumor activity evaluated in HCT116 human colon cancer cells.
Abstract: Maesa lanceolata is an ethno-medicinal plant distributed in Central and East Africa, especially Ethiopia and Kenya. It has been used as a traditional medicine against bacterial infections in the small intestine and viral infections in the liver and throat, as well as treatment for rheumatic arthritis. Even though the activity of M. lanceolata leaves has been studied in angiogenesis, which is significantly related to cancer and tumorigenesis, tangible evidence for cancer inhibiting activity of M. lanceolata seeds has not yet been obtained. To the best of our knowledge, this is the first study in which an anti-cancer compound has been identified from the seeds of M. lanceolata and its anti-tumor activity evaluated in HCT116 human colon cancer cells.

TL;DR: In this paper, the singularly perturbed parabolic partial differential equation is solved using implicit Euler method in the temporal discretization with exponentially varying operator in the spatial discretisation.
Abstract: This paper deals with numerical treatment of singularly perturbed parabolic differential difference equations having small shifts on the spatial variable. The considered problem contain small perturbation parameter (e) multiplied on the diffusion term of the equation. For small values of e the solution of the problem exhibits a boundary layer on the left or right side of the spatial domain depending on the sign of the convective term. The terms involving the shifts are approximated using Taylor’s series approximation. The resulting singularly perturbed parabolic partial differential equation is solved using implicit Euler method in the temporal discretization with exponentially fitted operator finite difference method in the spatial discretization. The uniform stability of the scheme investigated using comparison principle and discrete solution bound by constructing barrier function. Uniform convergence analysis has been carried out. The scheme gives second order convergence for the case e > N −1 and first order convergence for the case e « N −1 , where N is number of mesh interval. Test examples and numerical results are considered for validating the theoretical analysis of the scheme.

TL;DR: In this article, the effectiveness of Papaya seed extract for the removal of turbidity and total coliform in raw water sampled from Tulte River which serves as potable water for the society.
Abstract: The high cost of chemical coagulants for water treatment makes most people in rural community to resort to readily available surface water which are usually of low quality exposing them to different water-borne diseases. It is in this light, this research was conducted to assess the effectiveness of Papaya seed extract for the removal of turbidity and total coliform in raw water sampled from Tulte River which serves as potable water for the society. Jar test experiment was carried out via locally available Papaya seed as coagulant for treatment of high (392.7NTU) & medium (94.2NTU) turbidity level to obtained optimum operation condition of dose, pH and mixing time plus suitable extraction method. Those optimized parameters were then applied in household level of water treatment through manual coagulation (coagulation by hand) in order to qualify its effectiveness. The three extraction method used for coagulation/flocculation were Aqueous crude extract, salt crude extract and defatted salt extract which were gave best result at dosage of 20 ml,acidic condition of 6.0 and 60 min of agitation time. Coagulation test revealed that, superior total coliform removal of 96.32% was achieved through Defatted salt extract and gave residual turbidity of 4.25NTU which is acceptable based on WHO standard of drinking water. Its removal efficiency was good for all pH range especially at neutral and slightly basic pH condition. Overall, finding of this research suggest the potential of using Papaya seed as bio-coagulant for raw water treatment.
