Chloropicrin-induced toxic responses in human lung epithelial cells.

Chloropicrin is a slowly evaporating toxic irritant that is known to cause damage in the respiratory system. Here we used a lung epithelial cell line (A549) to study the molecular responses underlying chloropicrin toxicity. Glutathione (GSH), synthetic peptide and 2'-deoxyguanosine were used as in vitro trapping agents to identify early markers of chloropicrin toxicity.

Chloropicrin induces endoplasmic reticulum stress in human retinal pigment epithelial cells.

Chloropicrin is an aliphatic volatile nitrate compound that is mainly used as a pesticide. It has several toxic effects in animals and can cause irritating and other health problems in exposed humans. Since the mode of chloropicrin action is poorly understood, the aim of this study was to investigate molecular responses underlying chloropicrin toxicity.

[Motion sickness at sea and in the air].

Sea sickness was first described in 1881, and since then the syndrome has been described to be associated with travelling also in other means of transportation. Symptoms of motion sickness are quite common in otherwise healthy people. The symptoms are usually of short duration and last for not longer than three days.

Outbreak of 2009 pandemic influenza A(H1N1) in a Finnish garrison--a serological survey.

In September 2009, an outbreak of 2009 pandemic influenza A(H1N1) took place in a Finnish garrison. In November 2009, we performed a serological survey among 984 recruits undergoing their military service at the garrison and related the results to self-reported upper respiratory tract infection (URTI) with or without fever. Of 346 volunteers who donated a blood sample, 169 (49%) had pandemic influenza A(H1N1) virus-specific antibodies.

Capsaicinoids, chloropicrin and sulfur mustard: possibilities for exposure biomarkers.

Incapacitating and irritating agents produce temporary disability persisting for hours to days after the exposure. One can be exposed to these agents occupationally in industrial or other working environments. Also general public can be exposed in special circumstances, like industrial accidents or riots.
