| Title | : | Modeling of generation and propagation of cardiac action potential using fractional capacitance |
| Country | : | India |
| Authors | : | Harsh Wardhan || Siddharth Singh |
Abstract: This paper proposes modeling of canine cardiac action potential using fractional differential equations (FDE). The movement of ions across cardiac myocytes (heart muscle) generates a voltage signal which propagates along the body of the cell as action potential. The complex behavior of such physiological events can be understood by developing mathematical models that describe the biological phenomena. Typically, ordinary linear differential equations are used for constructing these mathematical models. In this paper we have shown that a non-integer order differential equation model can capture these events more precisely. Using FDE we are able to model cardiac action potential with a higher degree of accuracy compared to ordinary differential equations (ODE).

| Title | : | The effectS of Brassica oleracea plant extracts on tow type of leukemia cells (Invitro study) |
| Country | : | Iraq |
| Authors | : | Bashar Oda Jawad || Koloud W. AL Samaraie |
Abstract: Cold water hot water and ethanol extracts from Brassica oleracea plant they were prepared and tested for their antioxidant activity and efficacy against leukemia cells. All of the extracts showed significant antioxidant activity. All the extracts could kill the majority (50-75%) of abnormal cell among primary cells harvested from 3 patients with acute lympho-blastic leukemia (ALL) and 3 with acute myeloid leukemia (AML). DNA fragmentation patterns were detected within treated cells and inferred targeted cell death by apoptosis.The metabolites within the ext-racts may act as tumor inhibitors that promote apoptosis. In addition the plant extracts may be used to supplement or replace established drugs treatments .
Key words: Plant Extract, leukemia cells, Invitro study

Abstract: For the conservation of temperate orchids of Kashmir Himalaya various steps were carried out and a number of orchid speciesgrowing in the Kashmir Himalaya were subjected to ex-situ conservation strategies using different plant parts like pseudobulbs, adventitious roots, tubers and rhizome sections etc. Auxins particularly IBA have been found to induce germination and plantlet regeneration in rhizome sections of Spiranthes sinensis (Pers.) Ames. The apical bud elongated and developed into shoot in pots. The shoots grew well and flowered in 2-3 months. The results obtained suggest that this vulnerable medicinal orchid can be propagated easily through rhizome sectionsso as to achieve its mass multiplication.
