High-coercive cobalt ferrite nanoparticles were synthesized and studied for magnetic hyperthermia by direct injection of their suspension into a tumor and application of a strong audio-frequency magnetic field for heating. Physical （dynamic magnetic hysteresis and heat generation in both liquid and solid dispersions）, biological （toxicity and penetration of particles in therapeutic quantities into mouse tumor tissue） as well as other properties of the particles were studied. A model was developed to describe the magnetodynamics in suspensions of magnetic nanoclusters with an account for both Brownian and regular rotations, to provide understanding of observed phenomena. The experimental and theoretical techniques developed have formed a basis for controllable synthesis of the magnetic nanoparticles for low-frequency heat generation in medical and other applications.

The Functional Significance of Education In Dementia

引用

上海精神医学 1992年第S1期 59-64页

作者： William T. Liu elena yu MPH

This paper uses the sociological perspective to address the issue of the meaning in the observed association between education and dementia which we found in Shanghai. If a reduction in syuaptic reserve is the biologically plausible explanation for the development of dementia and AD, then it must have a social behavioral dimension for us to be able to assess the changes in the brain through neuropsychological tests and clinical evaluations, in the absence of autopsies. What are the socially plausible hypotheses which would be consistent with the biologically plausible explanation concerning synapse loss (or reduction in brain reserve) and dementia or AD? Sociological concepts are introduced to answer this question.

Caregivers' Burden in Shanghai: Study Design and Preliminary Findings

引用

上海精神医学 1992年第S1期 72-76页

作者： elena yu MPH William T. Liu

In 1986 when the Shanghai Survey of Alzheimer's Disease and Dementia (SSADD) was being planned, the VIC research team under William T. Liu's leadership decided to include a descriptive survey of caregivers. This paper describes our study design and reports the highlights of our findings. Children and in-laws comprise about 50% of Jing-An's caregivers. Very few elderly actually live alone. Caregivers of the physically disabled elderly reported more stress, less tolerance towards the behavioral problems of the etderly, and experienced greater burden of care than caregivers of the cognitively impaired.

Targeting of the AKT/m-TOR Pathway: Biomarkers of Resistance to Cancer Therapy——AKT/m-TOR Pathway and Resistance to Cancer Therapy

引用

中国肺癌杂志 2018年第1期21卷 63-66页

作者： Liudmila V SPIRINA Irina V KONDAKOVA Natalia V TARASENKO elena M SLONIMSKAYA Evgeny A USYNIN Alexey K GORBUNOV Zahar A yuRMAZOV Svetlana yu CHIGEVSKAYA Research Institute Tomsk National Research Medical Center of the Russian Academy of Sciences Russia

Resistance to cancer therapy continues to be a major limitation for the successful treatment of cancer. There are many published studies on therapy resistance in breast and prostate cancers; however, there are currently no data on molecular markers associated with resistance. The conflicting data were reported regarding the AKT/m-TOR signaling pathway components as markers predicting resistance. The AKT/m-TOR signaling pathway is involved in the development of many human cancers; its activation is related to cell proliferation, angiogenesis, apoptosis, as well as to therapy resistance. Molecular alterations in the AKT/m-TOR signaling pathway provide a platform to identify universal markers associated with the development of resistance to cancer therapy.

Features of physiological status of aged people in sparsely circumpolar areas of Russia

引用

Health 2012年第9期4卷 750-754页

作者： elena yu. Golubeva Raisa I. Danilova Northern Arctic Federal University Arkhangelsk Russia

Stable growth of the elderly age group is observed in the population of circumpolar areas of Russia. In northern conditions chronic pathology facilitates activity restriction development, changing the habitual lifestyle. Ageing process involves functional constraints of physical and mental activities, difficulties in doing everyday work. Aging changes of the nervous and respiratory systems are more characteristic of aged men and women living in the nursing home system of Russian urban circumpolar area. These changes are caused by worse psychological state, hypokinesia so there is a need in improving approaches in medical and social care services, in particular, introducing activating technologies and the micro-environment enhancement.
