Investigating the Effects of Changing Pattern AIDS Transmission on Prevalence Mycobacterium Tuberculosis in Patients with HIV by Microscopic and Molecular Methods

A new method is developed to measure the contact angle of air bubbles attached to an air-water interface. The measurements made from the microscopic interference pattern (Newton rings), which are obtained by viewing the bubble in reflected light, are used in conjunction with the solutions of the Laplace equations to the fluid interfaces to obtain the contact angle of the film. Measurements made...

Highly malignant brain tumors such as glioblastoma multiforme form complex growth patterns in vitro in which invasive cells organize in tenuous branches. Here, we formulate a chemotaxis model for this sort of growth. A key element controlling the pattern is homotype attraction, i.e., the tendency for invasive cells to follow pathways previously explored. We investigate this in two ways: we show...

Background and Objective: Evaluation of degenerative changes of motoneurons and their related synapses can be useful in understanding the mechanisms of neurodegenerative diseases and their potential treatment. The present electron microscopic and immunohistochemical study investigates the axotomy-induced...

Mining frequent patterns from large databases plays an essential role in many data mining tasks and has broad applications. Most of the previously proposed methods adopt apriorilike candidate-generation-and-test approaches. However, those methods may encounter serious challenges when mining datasets with prolific patterns and/or long patterns. In this work, we develop a class of novel and effic...

A microscopic, reversible model to study protein crystal nucleation and growth is presented. The probability of monomer attachment to the growing crystal was assumed to be proportional to the protein volume fraction and the orientational factor representing the anisotropy of protein molecules. The rate of detachment depended on the free energy of association of the given monomer in the lattice,...

background and objective: evaluation of degenerative changes of motoneurons and their related synapses can be useful in understanding the mechanisms of neurodegenerative diseases and their potential treatment. the present electron microscopic and immunohistochemical study investigates the axotomy-induced changes of adult spinal motoneurons up to 3 months following sciatic nerve transection. mat...

BACKGROUND AND AIMS During lateral root development a new meristem is formed within the mother root body. The main objective of this work was to simulate lateral root formation in Arabidopsis thaliana and to study a potential role of the principal directions in this process. Lateral root growth is anisotropic, so that three principal directions of growth can be distinguished within the organ. T...
