The appearance of phenotypic (and probably genetic) exoskeleton anomalies in Ixodes ticks, first discovered and described elsewhere, seems to be a global phenomenon clearly related to environment pollution by heavy metal ions. These external markers of cadmium accumulation in the tick indicate an enhanced risk of tick-borne infection related to an increased vectorial capacity.
Background and Purpose— It is not well established what are the features, if any, that distinguish symptomatic from asymptomatic carotid atherosclerotic plaques. Inducible heme oxygenase-1 (HO-1) is a component of cellular defense mechanisms against oxidative stress. We aimed to assess the presence of Helicobacter pylori (H pylori) and the expression of HO-1 in carotid atherosclerotic plaques of patients with and without prior neurologic symptoms attributable to the operated artery.
Carotid artery stenosis (CS) is a well-established risk factor for stroke. Increased proinflammatory chemokines, enhanced metallothionein (MT), and altered metal homeostasis may play roles in atherosclerosis progression and plaque destabilization. MT may sequester zinc during chronic inflammation, provoke zinc deficiency, and modulate NK cell cytotoxicity. A recent investigation of older patients with diabetes and atherosclerosis showed an association between the −209 A/G MT2A polymorphism,
Abstract Cadmium (Cd) has been in industrial use for a long period of time. Its serious toxicity moved into scientific focus during the middle of the last century. In this review, we discuss historic and recent developments of toxicological and epidemiological questions, including exposition sources, resorption pathways and organ damage processes.
Background Cadmium (group IIB of the periodic table of elements) is a heavy metal posing severe risks to human health.
Nausea and vomiting are symptoms associated with a wide variety of diseases and particular life conditions, such as pregnancy. The symptoms may occur in acute form or chronically depending on the underlying pathogenesis. In some cases, nausea and vomiting are directly triggered by food, e.g. in patients suffering from food allergy or food intolerances. In other cases,
Chronic liver diseases are disastrous to health. Many factors are associated with their prevalence, hence endemicity. These are mainly infectious, parasitic and toxic. A survey was conducted in a village south to Cairo. Large industries concerned with iron and steel industry, metals smelting, cement manufacturing and electric station were located north to the village. A systematic random sample of houses was selected.
The presence of lead in drinking water is not a new problem. Lead was historically used to produce pipes to carry water and later to solder iron and copper pipes. It is a ubiquitous heavy metal that has been used for centuries as a constituent in various products such as face powder, ceramic glazing, gasoline,
The city of Hermosillo, Sonora in northern Mexico was investigated for its heavy metals content. Samples of sedimented dust in roofs from 25 elementary schools were analyzed for their contents of Ni, Cr, Zn, Cd, Co, Ba, V, Pb, Fe and Cu after digestion with nitric acid. The results of the analysis were used to determine spatial distribution and magnitude of heavy metals pollution.
In 2005, the Olive Leaf Wholeness Center conducted a demonstration project that provided health assessment, testing, and results to 160 uniformed service personnel and residents of Lower Manhattan who were exposed to the air at Ground Zero following September 11, 2001, for extended periods of time. The program, known as Project Olive ReLeaf, found that most individuals had eight or more serious health complaints,
Background: Previous reports suggest that sarcoidosis occurs with abnormally high frequency in firefighters. We sought to determine whether exposure to World Trade Center (WTC) "dust" during the collapse and rescue/recovery effort increased the incidence of sarcoidosis or "sarcoid-like" granulomatous pulmonary disease (SLGPD).
Methods: During the 5 years after the WTC disaster,
