Serotyping is not sufficient to differentiate between Salmonella species that cause paratyphoid fever from the strains that cause milder gastroenteritis as these organisms share the same serotype Salmonella Paratyphi B (S. Paratyphi B). Strains causing paratyphoid fever do not ferment d-tartrate and this key feature was used in this study to determine the prevalence of these strains among the c...

In the presence of actinomycin D or a combination of actinomycin D and either camptothecin or alpha-amanatin. Aedes albopictus cells synthesize a variety of single stranded RNA species. These actinomycin D resistant species are ethidium bromide sensitive and they are present in the cell cytoplasm in an RNase resistant structure which has the sedimentation and buoyant density characteristics of ...

Let P d denote the space of all real polynomials of degree at most d. It is an old result of Stein and Wainger [4] that sup P ∈P d ˛ ˛ ˛ ˛ p.v. Z R e iP (t) dt t ˛ ˛ ˛ ˛ ≤ C d for some constant C d depending only on d. On the other hand, Carbery, Wainger and Wright in [2] claim that the true order of magnitude of the above principal value integral is log d. We prove that sup P ∈P d ˛ ˛ ˛ ˛ p.v....

The effective diffusion tensor of water, D, measured by diffusion tensor MRI (DT-MRI), is inherently a discrete, noisy, voxel-averaged sample of an underlying macroscopic effective diffusion tensor field, D(x). Within fibrous tissues this field is presumed to be continuous and smooth at a gross anatomical length scale. Here a new, general mathematical framework is proposed that uses measured DT...

Diabetes mellitus (DM) is characterised by alterations in the intrarenal renin-angiotensin system (RAS). Insulin treatment may reverse these changes by an unknown mechanism. We aimed to verify the association between somatic ACE with 136 kDa (sACE) and N-domain ACE with 69 kDa (nACE) from Wistar (W) rat tissue with DM. Three groups were studied: control (CT), insulin treated diabetic (DT) and u...

A 2(3) factorial experimental design has been used to quantitatively study individual and interaction effects of the nature of binder (N), binder concentration (c) and relative density of tablet (d) on the disintegration time (DT) and dissolution times, t1, t50 and t90, of paracetamol tablet formulations. The factorial design was also used to study the quantitative effects of pregelatinization ...

To elucidate the role of intracellular Na(+) kinetics in the mechanism for ischemic preconditioning (IPC), we measured intracellular Na(+) concentration ([Na(+)](i)) using (23)Na-magnetic resonance spectroscopy in isolated rat hearts. IPC significantly delayed the initial [Na(+)](i) increase (d[Na(+)](i)/dt) compared with non-IPC control, resulting in attenuation of Na(+) accumulation (Delta[Na...

A given nonincreasing sequence D = (d1, d2, · · · , dn) is said to contain a (nonincreasing) repetition sequence D∗ = (di1 , di2 , · · · , dik ) for some k ≤ n − 2 if all values of D −D∗ are distinct and for any dil ∈ D ∗ there exists some dt ∈ D −D∗ such that dil = dt. For any pair of integers n and k with n ≥ k + 2, we investigate the existence of a graphic sequence which contains a given rep...

and Applied Analysis 3 Definition 2.2 see 6 . A subset S of a BCI-algebra X is called subalgebra of X if x ∗ y ∈ S whenever x, y ∈ S. For a BCI-algebra X, we denote x ∧ y y ∗ y ∗ x for all x, y ∈ X 6 . For more details we refer to 3, 5, 6 . 3. t-Derivations in a BCI-Algebra/p-Semisimple BCI-Algebra The following definitions introduce the notion of t-derivation for a BCI-algebra. Definition 3.1....
