OBJECTIVE Many studies have shown that magnetic fields (MF) inhibit tumor growth and influence the function of immune system. However, the effect of MF on mechanism of immunological function in tumor-bearing mice is still unclear. METHODS In this study, tumor-bearing mice were prepared by subcutaneously inoculating Balb/c mice with hepatocarcinoma cell line H22. The mice were then exposed to ...

In this paper, the effectiveness of stiffness and damping of bearing is investigated on the natural frequencies of the rotor-bearing system. The rotor-bearing system consists of a shaft, two bearings and a disk between two bearings. Parallel spring-damper in horizental and vertical directions is considered for modeling the stiffness and damping of bearings. The gyroscopic effect is also conside...

Anti-Ig induced redistribution of different Ig subclasses was studied as a function of temperature and correlated with membrane phase transitions as revealed by electron spin resonance spectroscopy. Fluorescein isothiocyanate-coupled anti-IgG2 and anti-IgM antibodies induced patching and capping that proceeded with increasing rates from 2 degrees to 40 degrees (measured at 2 degrees intervals)....

This study evaluated the effect of immediate full weight bearing on abductor repair and clinical function after total hip arthroplasty (THA) using a direct lateral (modified Hardinge) approach. The surgical approach detached a bone flake with the abductors, providing a radiographic marker for abductor displacement and healing. Patients in whom weight bearing was restricted for 6 weeks (partial-...

Squeeze Film Dampers (SFD) are commonly used for passive vibration control of rotor-bearing systems. The Magnetorheological (MR) and Electrorheological (ER) fluids in SFDs give a varying damping characteristic to the bearing that can provide active control schemes for the rotor-bearing system. A common way to model an MR bearing is implementing the Bingham plastic model. Adding this model to th...

naturally occurred soil deposits inherit heterogeneity and anisotropy in their strength properties. the main purpose of this paper is to model the soil stratum with anisotropy consideration and spatially varying undrained shear strength by using random field theory coupled with finite difference numerical analysis to evaluate their effect on the bearing capacity of the shallow foundations. in t...

Antitumor resistance of mice bearing 3LL, M109, or Meth A tumors to a second tumor challenge was studied. The degree of inhibition of a second tumor growth in the tumor-bearing mice was a function of both the size of the primary tumor mass and the number of reinoculated tumor cells. Antitumor resistance of tumor-bearing mice is tumor nonspe cific and is observed only in the presence of the grow...

there exists an association between pi3k pathway licentious activity and the considerable feature of high metastatic potential of the genitourinary cancer cells. although du 145 and 5637 have functional phosphatase and tensin homolog (pten) tumor suppressor gene, which antagonizes pi3k function, pc-3 is null for pten gene. in pursuit to explain why pten bearing cell lines display high metastati...

 ABSTRACT Background: Correction of the uremic state by a functioning allograft often restores fertility in women of reproductive age. The rate of fertility significantly differs between industrial countries, developing and middle east countries. On the other hand the results of pregnancy in Kidney Transplantation (KTP) patients are significantly better than hemodialysis patients, and pregnancy...

INTRODUCTION Most astronauts experiencing prolonged microgravity undergo accelerated bone loss at a whole-body rate of 0.5-1% per month, with some load-bearing bones losing mass at normalized rates up to about 2.6% per month. The accompanying release of lead (Pb) stored in bones would increase the concentration of Pb in the blood (PbB), thereby complicating efforts to set acceptable Pb concentr...
