BACKGROUND Exposure to organic solvents is common among workers. OBJECTIVE To assess neurobehavioral effects of long-term exposure to organic solvents among rubber workers in Tehran, Iran. METHODS Across-sectional study was conducted on 223 employees of a rubber industry. The participants completed a data collection sheet on their occupational and medical history, and demographic characteri...

Background: Airport workers are continuously exposed to different levels of radiofrequency microwave (RF/MW) radiation emitted by radar equipments. Radars are extensively used in military and aviation industries. Over the past several years, our lab has focused on the health effects of exposure to different sources of electromagnetic fields such as cellular phones, mobile base stations, mobile ...

Digit length ratios, especially the second-to-fourth digit ratio (2D : 4D), are associated with various pathological and behavioural conditions in many species including humans and are dependent upon prenatal androgen to oestrogen balance. It is unknown whether digit ratios are modified by environmental exposure to ubiquitous endocrine disruptors. We studied the effect on adult male Wistar rat ...

In this paper, we present one of the first direct microeconometric evidence of the impact of trade protection on household poverty in Ghana. The study examines the impact of Ghana’s trade policy reforms in the 1990s on poverty. We match trade policy measures at the two-digit ISIC level to household survey data for 1991/92 and 1998/99. We emphasize the possibility that the effect of protection o...

In light of the need for detailed and timely internationally comparable trade price indices, this paper describes a multi-tiered methodology to mitigate many empirical challenges associated with using customs data, provide more robust estimates unit value indices (UVIs) by country product. UVIs are available both exports imports, reporting CPA 2-digit level classification. Although approach can...

OBJECTIVE In mammals, high parental testosterone levels present around the time of conception are thought to skew offspring sex ratio toward sons. The second to fourth digit ratio (digit ratio) is now widely accepted as a negative correlate of prenatal testosterone. Thus, we investigated the association between digit ratio and offspring sex ratio. METHODS A total of 508 Korean patients (257 m...

Circulating adult testosterone levels, digit ratio (length of the second finger relative to the fourth finger), and directional asymmetry in digit ratio are considered sexually dimorphic traits in humans. These have been related to spatial abilities in men and women, and because similar brain structures appear to be involved in both spatial and musical abilities, neuroendocrine function may be ...

A previously unreported subset of high-pressure injection injuries, namely those involving solvents used in the garment dry cleaning industry, is presented. Dry cleaning solutions contain isoparaffinic hydrocarbons, methoxypropanol, and dichlorofluoroethane. Although these solvents have limited potential for systemic toxicity, severe local toxicity causing tissue necrosis often results in loss ...
