Pseudomonas Aeruginosa: The Air-Breathing Troublemaker

One of the most dangerous super-bug today is Pseudomonas aeruginosa. And like any superbug available antibiotics today fails to work against its new strains. Knowing these bacteria allows you to be more careful in environments or places where these troublemakers about, and statistically infects people.

THE bacteria Pseudomonas aeruginosa (PA) normally resides in soil, water, skin flora, and man-made environments. It can be found regularly on the surfaces of plants, and occasionally, of animals. It is one of the most vigorous, fast-swimming bacteria seen in hay infusions and pond water samples. It is a stranger to the internal parts of the human body, though.

Characteristically PA needs minimal nutrition. It is even often observed growing in distilled water. It grows optimally at room temperature. And it has predilection to grow in moist environments, thriving on biofilms.

Still it is opportunistic. It exploits certain break in the human defenses to initiate infection. In fact, PA almost never infects uncompromised tissues. But if the defenses break down, it can infect almost any part of the body.

Because of that unnatural virulence, PA can cause... [READ MORE]

POST-PRESS: Narcissistic Disorder, Ground for Annulment

On 20 May 2011 (Friday), the First Division of the Philippine Court of Appeals dismissed the plea that Julie Balarbar, wife of 15 years of House Deputy Speaker Lorenzo Tañada III, filed questioning the November 25, 2010 decision of the Makati Regional Court declaring the marriage null and void on the ground that Balarbar had been diagnosed with narcissistic personality disorder (NPD). Pyschiatric evaluation show a diagnosis of NPD with anti-social features, from her involvement in a shoplifting incident, her closeness to and trips abroad with her male students, and a kissing incident with a co-professor. The Diagnostic and Statistical Manual of Mental Disorder Fourth Edition (DSM IV-TR) enumerated nine indicators of NPD, with only five of them needed for the diagnosis. It is not clear however which indicators have been found in the case of the Tañada annulment case. The Archdiocese of Manila also declared their canonical marriage void ab initio (void from the start) due to "gra

Sex Industry Weathers Financial Crises

Varmus Christopher Forbes.com 12/29/08 14:00:05 GMT The sex industry traces back to 500 B.C., when traders from the Greek port of Miletus sold olisbos, an early version of the dildo. Today, the business of sex (including pornography) now runs into the tens of billions of dollars. (No official estimates are available; Wall Street analysts don't tend to track this stuff.) And while print and video sales are ebbing, as more free adult content has become available online, sales of un-reproducible sexual aids are still healthy. "Of course, there's concern about the economy, but right now our sales are growing," says Michael Trygstad, founder of Wet, a lubricant manufacturer in Van Nuys, Calif. "We've grown 30% this year alone. We've had to completely automate our factories to meet the tremendous demand. People are deciding to stay at home and engage in inexpensive entertainment.'' Slick marketing--and the ability to shop anonymously online--helps, too

POST-PRESS: Filipinos Get Vitamin C from Vegetables

The DOST Food and Nutrition Research Institute (FNRI) recently issed a survey showing that 34 to 53 percent of Vitamin C consumed among Filipinos came from vegetables. Fruits merely contribute around 19 to 29 percent as a source. More than 50 percent of Vitamin C intake among adults, the elderly, and lactating women came from vegetables. Adolescent and pregnant women comprised 42.2 and 41.7 percent, respectively. Children have the lowest use of vegetables as Vitamin C source, contributing only 34.6 percent to diets among 6-12 agers and 17,2 percent among those ageing 6 months to 5-year olds. Vitamin C-rich vegetables include leafy greens like malunggay, ampalaya, petsay, saluyot, peppers (red and green), sitsaro and raw cabbage. Despite this figures, only 3 in every 10 households met the estimated average requirement (EAR) for Vitamin C, which is 80 percent of the recommended intake of the vitamin. And worse vegetable consumpion is on the downtrend over the years. It has decreased
