background: this study is performed to reveal most common species and subspecies of leptospires that are main causes of hu­man leptospirosis in guilan, northern province of iran. methods: we performed igm-elisa and mat on 282 blood samples from patients who attended to 3 hospitals in the flat area of guilan province with clinical symptoms consisted with leptospirosis.  all specimens with titers...

background leptospirosis is a systemic infectious disease caused by pathogenic bacteria belonging to the species of leptospira, it is considered to be the most common zoonosis in the world. this is a serious and sometimes fatal infection which is transmitted from animals to humans by entering the digestive tract or mucosal membrane. within the initial 10-12 day period, the patient may experienc...

the ultraviolet-visible (uv) spectra of toluene, ortho-bromo and para-bromo toluene in different solvents have been studied. the electric dipole moments and polarizabilities in the molecular excited electronic states were determined. it was found that the electric dipole moments for the excited states (µ*) and the ground states (µ) of these compounds are equal, and the change in dipole moment i...

JENNIFER J. YOUNG: Cytoskeleton Micromechanics: A Continuum-Microscopic Approach (Under the direction of Sorin Mitran) Creating accurate, whole-cell scale models of the cytoskeleton is computationally challenging, due to the material’s highly heterogeneous microstructure. Continuumbased models, homogenization methods, and coarse grained models are common modeling approaches. These methods utili...

Microscopic state counting for a black hole in Loop Quantum Gravity yields a result proportional to horizon area, and inversely proportional to Newton’s constant and the Immirzi parameter. It is argued here that before this result can be compared to the BekensteinHawking entropy of a macroscopic black hole, the scale dependence of both Newton’s constant and the area must be accounted for. The t...

We define the dielectric constant (susceptibility) that should enter the Maxwell boundary value problem when applied to microscopic dielectric interfaces polarized by external fields. The dielectric constant (susceptibility) of the interface is defined by exact linear-response equations involving correlations of statistically fluctuating interface polarization and the Coulomb interaction energy...

The decay constant of the QCD axion is required by observation to be small compared to the Planck scale. In theories of “natural inflation,” and certain proposed anthropic solutions of the cosmological constant problem, it would be interesting to obtain a large decay constant for axion-like fields from microscopic physics. String theory is the only context in which one can sensibly address this...

background: differentiation between the muscularis mucosae (mm) and muscularispropria (mp) of the bladder remains challenging. objective: to identify mm- and mp-specific antigens that could be of potential value for staging of urothelialcarcinomain a pilot study. method: the expression of 12 protein antigens in 11 human bladder specimens was examined. there were 5 post radical cystectomy specim...
