Infection from Toxocara species may give rise to a large array of clinical symptoms, including apparent manifestations of allergy such as asthma, urticaria/angioedema, and dermatitis. We report a case, thus far not described, of contact dermatitis attributed to nickel allergy but caused by Toxocara infection. The patient was a 53-year-old woman presenting from 10 years a dermatitis affecting he...

A new, cost-effective, and environmental-friendly cloud point extraction methodology was described for enrichment of copper, manganese and nickel in several water samples. The method involves the complexation of copper, manganese or nickel with 2-amino-6-(1,3-thiazol-2-diazeyl)-phenol at pH 7.0, then extraction into Triton X-114. After dilution of the surfactant-rich phase with acidified methan...

The carbothermic co-reduction of nickel laterite ore and red mud realized the simultaneous reduction nickel, iron in ore, at high efficiency. Nickel were recovered form ferronickel. size characteristics ferronickel particles grindability products are essential for obtaining good technical indicators. influence conditions on particle relative was investigated by a test, analysis, determination. ...

Nickel is an important element in the metal alloy industry. In Indonesia, nickel resources are found many areas form of rocks such as pyrophyllite. Froth flotation a method commonly used mining industry to extract metals from mineral rocks. However, concentrates yields tend be relatively low. This often influenced by several factors pH solutions and stirring speed process. Therefore, this study...

BACKGROUND Several materials are available in the market that work on the principle of protein magnetic fishing by their histidine (His) tags. Little information is available on their performance and it is often quoted that greatly improved purification of histidine-tagged proteins from crude extracts could be achieved. While some commercial magnetic matrices could be used successfully for puri...

Allergic contact dermatitis due to nickel salts is common. It is therefore important to measure the permeation of these salts through the stratum corneum (SC), the primary rate-limiting domain in skin. An advanced diffusion system and analytical techniques now enable better measurement of the flux than was possible in earlier experiments. Human SC was prepared by trypsinization of dermatomed ca...

Abstract This paper reviews reported methods of the electrochemical deposition nickel layers which are used as target materials for accelerator production medical radioisotopes. The review focuses on electrodeposition carried out from aqueous electrolytes. It describes main challenges related to preparation suitable Ni layers, such work with limited amounts expensive isotopically enriched nicke...

In this study, a hydrometallurgical treatment involving the solvent extraction and recovery of some heavy metals from a sulphuric acid leach solution of galvanic sludge, using di-(2-ethylhexyl)-phosphoric acid (D2EHPA) and bis-(2,4,4-trimethylpentyl)-phosphinic acid (Cyanex 272), both diluted in kerosene, has been investigated. The preliminary tests revealed the necessity to remove other metal ...
