Iowa towns of 1000-10,000 population, whose water came solely from wells of over 500 feet (152 meters) in depth and was not treated by a process that would remove radioactivity, were identified. Age-adjusted, sex-specific, cancer incidence rates were determined for these towns for the years
Any and all chemicals generated by human activity can and will find their way into water supplies. The types and quantities of carcinogens present in drinking water at the point of consumption will differ depending on whether they result from contamination of the source water, arise as a consequence
Data from a population-based case-control interview study of incident bladder cancer in 10 areas of the United States were used to estimate relative risks among white men (2,116 cases, 3,892 controls) and women (689 cases, 1,366 controls) according to beverage intake level and type of water source.
Moderate body deuteration combined with a cytostatic drug [methotrexate (MTX)] significantly increases the survival time of young adult DBA/2 mice bearing transplantable P815. L5178Y, or L1210 tumors. Neoplastic cells were grown in vitro from tumor stock and injected i.p. into mice from two groups,
Published reports have revealed increased risk of colorectal cancers in people exposed to chlorinated drinking water or chemical derivatives of chlorination. Oestrogen plays a dual positive functions for diminishing the possibilities of such risk by reducing the entrance, and increasing the
The incidence of gastric carcinoma was analysed in Zabrze in the years 1965-1975 taking into account the sex, age, place of birth (autochthonous and immigrated populations) and place of residence in different city districts in relation to drinking water hardness. A correlation was revealed between
The objectives of this study were to (1) examine the relationship between total trihalomethanes (TTHM) levels in public water supplies and risk of esophageal cancer occurrence and (2) determine whether calcium (Ca) and magnesium (Mg) levels in drinking water modify the effects of TTHM on risk to
The objectives of this study were to (1) examine the relationship between total trihalomethanes (TTHM) levels in public water supplies and risk of development of kidney cancer and (2) determine whether hardness levels in drinking water modify the effects of TTHM on risk of kidney cancer induction. A
BACKGROUND
Water is an indispensable nutrient because of its physicochemical properties. People seem to consume more water than before although the scientific basis for this has not been firmly established.
METHODS
We present a short overview of data retrieved from the databases PubMed and Ovid,
UNASSIGNED
The current review will attempt to describe the important lessons learned from published randomized controlled trials (RCT) comparing water immersion (WI) or water exchange (WE) techniques with gas insufflation colonoscopy. Air insufflation (AI) to distend the colon to permit
Antitumor effect of water-in-oil-in-water type adriamycin emulsion (emulsion ADM) was examined in comparison with free ADM on the survival time of ICR male mice bearing Ehrlich solid tumor after a subcutaneous inoculation and on the tumor growth by the subcutaneous (SC-SC) or intraperitoneal
OBJECTIVE
To assess the relationship between microcystins (a blue-green algal toxin) in drinking water and colorectal cancer.
METHODS
Eight townships were randomly selected as study sites in Haining city of Zhejiang province, China. Four hundred and eight colon and rectum carcinoma cases diagnosed
