tion of Karpas 299 cells with immobilized antibodies to CD30 was found to potently induce cell death, whereas in the same experiment the addition of these antibodies in their soluble form did not induce cell death and actually slightly enhanced viability (Figure 1). Also noteworthy is the fact that, in the earlier report by Gruss et al4 in which the cytotoxic effects of M44 and M67 were origina...

UNLABELLED Homeopathic medicine is commonly believed to be relatively harmless. However, treatment with improperly used homeopathic preparations may be dangerous. CASE REPORTS Case 1 presented with melanosis and keratosis following short-term use of Arsenic Bromide 1-X followed by long-term use of other arsenic-containing homeopathic preparations. Case 2 developed melanotic arsenical skin les...

The consequences of climate change, and the increased accumulation metalloids, like arsenic (As), in environment, are significantly affecting crop performance yield. Arsenic interferes with various plant biochemical physiological processes, which result diminished growth development. Magnesium oxide nanoparticles (MgO-NPs) can improve contribute to tolerance heavy metal/metalloid toxicity. Duri...

BACKGROUND Arsenic is metabolized through a series of oxidative methylation reactions by arsenic (3) methyltransferase (As3MT) to yield methylated intermediates. Although arsenic exposure is known to increase the risk of atherosclerosis, the contribution of arsenic methylation and As3MT remains undefined. OBJECTIVES Our objective was to define whether methylated arsenic intermediates were pro...

For the past 60 yr, chromate-copper-arsenate (CCA) has been used to pressure-treat millions of cubic meters of wood in the United States for the construction of many outdoor structures. Leaching of arsenic from these structures is a possible health concern as there exists the potential for soil and groundwater contamination. While previous studies have focused on total arsenic concentrations le...

Arsenic is a toxic metalloid existing widely in the environment, and its removal from contaminated water has become a global challenge. The use of bacteria in this regard finds a promising solution. In the present study, Exiguobacterium sp. As-9, which is an arsenic resistant bacterium, was selected with respect to its arsenic removal efficiency. Quantification of arsenic in the water treated w...

In continuation of our short-term pilot studies reported earlier, results on certain toxicity biomarkers in volunteers who continued to take the potentized Arsenicum album 200C till 2 years are presented. Out of some 130 "verum"-fed volunteers of pilot study, 96 continued to take the remedy till 6 months, 65 till 1 year and 15 among them continued till 2 years. They provided samples of their ur...

Research in our laboratory has demonstrated that a trivalent form of arsenic such as arsenic trioxide (AT) has the ability to cause significant cytotoxicity, and induction of a significant number of stress genes in human liver carcinoma cells (HepG2). However, the literature also indicates that the toxicity of arsenic depends on its chemical form. To test this hypothesis, we further evaluated t...

Arsenic has a suppressive influence on spermatogenesis and induces impairment in male reproductive system due to oxidative stress. The present study was aimed to test the arsenic induced toxicity and protection by Chlorophytum borivilianum. The effect of sodium arsenite (4 mg/(kg body weight (bw) x day)) via double distilled water without or with C. borivilianum (800 mg/(kg bw x day)) was evalu...

Inorganic arsenic is a potent carcinogen and environmental pollutant. More than one hundred million people are reported to be exposed to elevated concentrations of arsenic mainly via drinking water. Essential trace elements can affect toxicity of metals by interacting with metals at the primary site of action and can also modify the body's response to toxic metals by altering their metabolism a...
