Hair dyes raise the risk of breast cancers especially among black women says study

A new study has confirmed that permanent hair dyes and chemical hair straightener use are associated with breast cancers especially among African American women. There have been animal studies that reveal that these hair dyes and chemicals used for straightening the hair are associated with cancers. Human studies however have not shown consistent results establishing the relationship between the chemicals and the cancers.

New method to improve skeleton of common chemicals

Every chemical, from the simplest to the most complex, have a structural skeleton of atoms. The atoms can be added or removed to transform the chemical into different types, for use in different applications. For many pharmaceutical and agricultural chemicals, the skeleton consists of a multi-membered carbon ring called a carbocycle.

Study reveals exposure of new-born babies in NICU environment to harmful chemicals

A multidisciplinary team of scientists from Granada has warned for the first time of the presence of bisphenol A (BPA) and parabens (PBs) in a wide range of plastic medical devices, fabrics, personal care products (including topical creams), and nutritional supplements in hospital neonatal intensive care units, coming into direct contact with new-born babies.

Medicinal plants: from genes to drugs

We eat plants, wear their products, burn them for fuel, and use them to build our houses. Plants are the very basis of the food chain on earth. They are also the source of oxygen in the atmosphere, and a treasure house containing a host of compounds that have biological effects on the body. Some of these chemicals are produced as self-defence, to guard against pests and diseases.

Sanitization error might possibly have exposed hundreds to HIV at Indiana hospital

An Indiana hospital is in the news for all the wrong reasons. An accidental failure by one of the seven sterilization technicians working at the hospital was recently discovered. The technician failed to carry out a single step in a protocol concerning the sanitization of surgical equipment at Goshen Hospital, over a period from April 1 to September 30.
