Lead is one of the heavy metals associated with a number of health problems such as abdominal pains, constipation and loss of appetite, nausea, vomiting, insomnia, headache, irritability, dizziness and lead encephalopathy. The major source of lead into the environment is through emission from auto exhaust in countries still using leaded fuel, with other contributors being cigarette smoke, burni...

Early generation ceramic articulations were problematic in terms of ceramic implant fracture and wear. Although the mechanical properties of ceramic material have improved during the last three decades, ceramic component fracture remains an issue. Many authors have reported fractures of the ceramic head, and a few have described ceramic acetabular insert fracture. However, these complications a...

Hallopeau in 1897 1.2 described acrodermatitis continua as characterised by sterile, pustular eruption affecting the skin of the distal phalanges of the fingers and toes, which eventually led to destructive changes of the affected digits. The lesions are usually symmetrical and give rise to persistent erythematous, glazed area of skin. These on occasions developed into generalised pustular psor...

Despite the recent declines in environmental lead exposure in the United States and Mexico, the potential for delayed toxicity from bone lead stores remains a significant public health concern. Some evidence indicates that mobilization of lead from bone may be markedly enhanced during the increased bone turnover of pregnancy and lactation, resulting in lead exposure to the fetus and the breast-...

Traditional pottery manufacturing involves firing of the ceramics in kilns, a process that leads to high concentrations of airborne particles that are harmful to human health. In order to assess the associated exposure levels and the involved risks, here, for the first time, we investigate the size, the concentration and the elemental composition of the particles emitted during the different st...

Quality of glazed (G) and non-glazed air-blast frozen rainbow trout (Oncorhynchus mykiss) was evaluated after applying different modern (M: microwave oven; U: ultrasonic; HVEFT: high voltage electrical field; O: ohmic heating) and conventional (S: steam cooking; W: water; R: refrigeration) thawing methods. Glazed frozen samples thawed by modern and conventional methods showed an increase in pro...

BACKGROUND Squeaking after ceramic-on-ceramic total hip arthroplasty is a relatively uncommon phenomenon. It usually does not require treatment in the absence of pain, mechanical symptoms, and/or relentless squeaking. The purpose of this investigation was to report on four patients who presented with hip pain and squeaking due to fractured ceramic liners after ceramic-on-ceramic total hip arthr...

Comares Hall is the most majestic room in the Alhambra. It is located within Comares Tower, which was built by artisans from the nearby town of Comares. The Hall measures 30’x30’, with a 60-foot-high domed ceiling and nine large windows. The ceiling, beams, and doors of Comares Hall are of carved wood, the floors and wainscoting are glazed earthenware mosaic, and other ornamental surfaces are o...
