Association between copper excess, zinc deficiency, and TP53 mutations in esophageal squamous cell carcinoma from Kashmir Valley, India–a high risk area

Abstract:
Trace element deficiency or excess is implicated in the development or progression in some cancers. Here we report the elevated level of copper and low level of zinc in the plasma of esophageal cancer patients in Kashmir India–a high incidence area. The average level of copper was significantly higher (P < 0.0001) for patients [...]

Copper excess, zinc deficiency, and cognition loss in Alzheimer’s disease

Abstract:
In this special issue about biofactors causing cognitive impairment, we present evidence for and discuss two such biofactors. One is excess copper, causing neuronal toxicity. The other is zinc deficiency, causing neuronal damage. We present evidence that Alzheimer’s disease (AD) has become an epidemic in developed, but not undeveloped, countries and that the epidemic […]

Protective role of copper, zinc superoxide dismutase against UVB-induced injury of the human keratinocyte cell line HaCaT

Abstract:
On the basis of our recent observation that copper, zinc-superoxide dismutase and manganese-superoxide dismutase change differently following a single exposure to ultraviolet-B irradiation in the human keratinocyte cell line HaCaT, we have examined the possible role of endogenous copper,zinc-superoxide dismutase or manganese-superoxide dismutase against ultraviolet-B-induced reactive-oxygen- species-mediated keratinocyte injury in vitro. To evaluate the […]

Zinc deficiency induces dysregulation of cytokine productions in an experimental colitis of rats

Abstract:
Dextran sulfate sodium (DSS)-induced colitis is an experimental model of ulcerative colitis, although the precise mechanism has not yet been elucidated. We investigate whether Zn deficiency affects the pathogenesis of colitis induced by DSS with a focus on immune responses. Male WKAH/Hkm Slc rats were fed either a Zn-adequate (ZA, 30 mg Zn/kg diet) […]

Zinc sulphate solution enema decreases inflammation in experimental colitis in rats

Abstract:
BACKGROUND: It has been reported that zinc sulphate contributes an anti-inflammatory action in many animal models; however, the impact of zinc in colitis remains unclear. The aim of the present study was to examine the role of zinc sulphate in experimental colitis.METHODS: Colitis was induced by 2,4,6-trinitrobenzenesulphonic acid (TNB) in rats. Beginning at the […]

Effect of zinc supplementation on intestinal permeability in experimental colitis

Abstract:
Increased small-intestine permeability has been documented in experimental colitis in the rat. Zinc supplementation improves mucosal repair in patients with diarrhea, as well as paracellular permeability in malnourished guinea pigs. In this study, we sought to evaluate the effect of zinc supplementation on small-and large-intestine tight junctions in rats with acute colitis. Rats were […]

Innovative uses for zinc in dermatology

Abstract:
Severe zinc deficiency states, such as acrodermatitis enteropathica, are associated with a variety of skin manifestations, such as perioral, acral, and perineal dermatitis. These syndromes can be reversed with systemic zinc repletion. In addition to skin pathologies that are clearly zinc-dependent, many dermatologic conditions (eg, dandruff, acne, and diaper rash) have been associated and […]

Hidradenitis suppurativa and zinc: a new therapeutic approach. A pilot study

Abstract:
BACKGROUND: Hidradenitis suppurativa (Verneuil’s disease) is a chronic suppurative dermatosis involving apocrine glands with a severe impact on the quality of life, which is enhanced by the fact that the drugs usually prescribed are poorly effective.OBJECTIVE: We discuss a new therapeutic approach based on zinc salts.METHODS: We performed a pilot study on 22 patients, […]

Zinc and the skin

Abstract:
Zinc is an essential trace element integrally involved in a wide range of metabolic processes required for tissue growth and repair as well as being necessary for maintaining host defences. Zinc deficiency can occur from lack of adequate dietary intake, decreased intestinal absorption, and increased losses in the gastrointestinal tract, urine, and sweat. The […]
