because of the importance of microbial metabolites of cholesterol as precursors in the synthesis of steroidal drugs, we decided to study the ability of arthrobacter simplex to degrade cholesterol. arthrobacter simplex cleaves the side chain of cholesterol in the presence of 2,2'-dipyridyl and produces 4-androstene-3,17- dione (ad) and androsta- 1,4-diene-3,17-dione(add). two other intermed...

in this paper, the concept of fuzzy convex subgroup (resp. fuzzy convex lattice-ordered subgroup) of an ordered group (resp. lattice-ordered group) is introduced and some properties, characterizations and related results are given. also, the fuzzy convex subgroup (resp. fuzzy convex lattice-ordered subgroup) generated by a fuzzy subgroup (resp. fuzzy subsemigroup) is characterized. furthermore,...

the present case report introduces a patient with fluent aphasia, anterograde amnesia and anosmia due to herpes simplex encephalitis after her first delivery. the left medial temporal lobe was one of the main areas involved. on aphasia testing she showed severe anomia on both confrontation and free recall, agraphia, alexia, repetition disorder and some auditory comprehension impairments. therap...

We present a formulation of Regge Calculus where arbitrary coordinates are associated to each vertex simplicial complex and the degrees freedom given by metric on simplex. The lengths edges thus determined left invariant under transformations discrete set coordinates, provided transforms accordingly. Invariance coordinate entails tensor calculus our follows closely usual formalism continuum the...

conclusions herpes simplex virus was present in more patients with ms than healthy cases. hsv may be directly or indirectly associated with ms development. further comprehensive molecular studies are needed to confirm the etiopathologic association between hsv and ms disease. results totally, 63 (76.8%) patients with ms showed a history of hsv exposure by anti-hsv testing compared to 70 (78.7%)...

background :wide distribution and low half-life of acyclovir has led to a high dose consumption of the drug. recent studies have shown that encapsulation of acyclovir in nano-carriers can increase effectiveness and decrease its side effects. we investigated the inhibitory effect of acyclovir loaded nano-niosomes against herpes simplex virus type-1 (hsv-1) in cell culture.   methods : in-vitro c...

there are two interesting methods, in the literature, for solving fuzzy linear programming problems in which the elements of coefficient matrix of the constraints are represented by real numbers and rest of the parameters are represented by symmetric trapezoidal fuzzy numbers. the first method, named as fuzzy primal simplex method, assumes an initial primal basic feasible solution is at hand. t...

In this paper, the concept of fuzzy convex subgroup (resp. fuzzy convex lattice-ordered subgroup) of an ordered group (resp. lattice-ordered group) is introduced and some properties, characterizations and related results are given. Also, the fuzzy convex subgroup (resp. fuzzy convex lattice-ordered subgroup) generated by a fuzzy subgroup (resp. fuzzy subsemigroup) is characterized. Furthermore,...

  Nonlinear Dust lattice modes are studied in a hexagonal two-dimensional dusty plasma lattice, in presence of charge gradient of dust particles. In this lattice, such gradients affect nonlinear behavior of dust lattice waves. The amplitude modulation of off-plane transverse dust lattice wave packets is investigated considering the anisotropy of interactions, caused by the height-dependent char...
