Cancer is a Preventable Disease that Requires Major Lifestyle Changes

This year, more than 1 million Americans and more than 10 million people worldwide are expected to be diagnosed with cancer, a disease commonly believed to be preventable. Only 5–10% of all cancer cases can be attributed to genetic defects, whereas the remaining 90–95% have their roots in the environment and lifestyle. The lifestyle factors include cigarette smoking, diet (fried foods, red meat), alcohol, sun exposure, environmental pollutants, infections, stress, obesity, and physical inactivity. The evidence indicates that of all cancer-related deaths, almost 25–30% are due to tobacco, as many as 30–35% are linked to diet, about 15–20% are due to infections, and the remaining percentage are due to other factors like radiation, stress, physical activity, environmental pollutants etc. Therefore, cancer prevention requires smoking cessation, increased ingestion of fruits and vegetables, moderate use of alcohol, caloric restriction, exercise, avoidance of direct exposure to sunlight, minimal meat consumption, use of whole grains, use of vaccinations, and regular check-ups. In this review, we present evidence that inflammation is the link between the agents/factors that cause cancer and the agents that prevent it. In addition, we provide evidence that cancer is a preventable disease that requires major lifestyle changes

Measured broadband reverberation characteristics in Deep Ocean

62-66Broad band reverberation measurements were collected in deep water (2067m) off Vizag. TNT scare charges (0.450 kg) were used as sound sources which were expended from the ship. The signals were recorded using two hydrophones deployed from the ship. The sound speed profile exhibits 63m duct with a limiting ray angle of about 4.47o and lower cut off frequency of 177 Hz. A flat plateau and then sudden fall of 10 dB near ~12-13s on the reverberation characteristic in deep water is related to the effect of sound speed profile and water depth. This strong reverberation return will have major consequences on the reverberation limited sonar performance. This effect is correlated with ray theory based model and the results are presented

Decipic acid and 12-acetyl apetalic acid from <i style="">Calophyllum decipiens</i>. Wight

393-397Triterpenes, stigmasterol, thwaitesii xanthone, apetalic acid, two new chromanones, decipic acid and 12-acetyl apetalic acid are isolated for the first time from the ethyl acetate extract of the bark of Calophyllum decipiens, Guttiferae. Structures are elucidated by spectral studies. Apetalic acid shows appreciable amount of radical scavenging activity on comparison with trolox (standard) using DPPH free radical. It also shows antibacterial activity against Mycobacterium tuberculosis H37Rv at 100 μg/mL using anti-TB drug rifampicin at 0.5 μg/mL
