My Life With Science!

Despite this exemplary academic trajectory, what makes Dorly a special human being are her unique qualities: loyalty, courage, tenderness, and tenacity. Woman, mother, sister and friend, she is endowed with profound sensitivity, a conciliatory spirit and the ability to aggregate people and ideals around a greater good. Her respect for life, in all its forms, has always guided her in search of health promotion and a better life for all. And so, in its continuous overcoming of challenges, guided by an acute scientific curiosity and its non-conformity with the paradigms and limitations of traditional medicine, in an untiring spirit and an unwavering purpose of serving collective interests, firmly carried out research based on highly diluted drugs and complex biological response modifiers. A significant part of the results of his efforts and his holistic view is presented in this book which, as an author, proposes to contribute to life, health and the construction of happiness for all.

The presence of the unexpected in my life!

Dra. Dorly de Freitas Buchi, the renowned Brazilian researcher, holds a Ph.D. in Biological Sciences (Biophysics) from the Federal University of Rio de Janeiro. His solid academic background is reflected in the publication of several scientific articles in the field of Cell Biology. Professor, for more than 40 years at the Federal University of Paraná, she combines extensive experience in higher education, both in undergraduate and graduate courses, and effective contributions in the sphere of the university administration. Its orientation activities are remarkable, from scientific initiation to doctorate, having promoted the training of a large number of young scientists.

Nowadays, 2021 January, many cases of bird flu have been reported in India. Several states have issued bird flu alert. The Centre has warned the states over possibility of the disease spreading to humans.

Influenza A virus subtype H5N1 (A/H5N1) is a subtype of the influenza A virus which can cause illness in humans and many other animal species. A bird-adapted strain of H5N1, called HPAI A(H5N1) for highly pathogenic avian influenza virus of type A of subtype H5N1, is the highly pathogenic causative agent H5N1 flu, commonly known as avian influenza (“bird flu”). Till now there is “no evidence of sustained human-to-human transmission” of the virus (WHO). Human cases of H5N1 avian influenza occur occasionally, but it is difficult to transmit the infection from person to person. When people do become infected, the mortality rate is about 60%. It was in 1997 when humans are first known to have contracted bird flu following an outbreak in a live bird market of Hong Kong. It was the H5N1 strain of the virus, and 6 out of 18 infected humans died of the disease.

Most human infections with Asian HPAI H5N1 have occurred among children and adults younger than 40 years old. Mortality has been highest in people aged 10-19 years old and in young adults. Research has shown that a highly contagious strain of H5N1, one that might allow airborne transmission between mammals, can be reached in only a few mutations. As a standard precaution, WHO recommends that poultry, poultry products and wild game birds should always be prepared following good hygienic practices, and that poultry meat should be perfectly cooked.

Investigators hypothesized that this virus is lethal because it induces an unusually potent proinflammatory cytokine response. The virus can trigger levels of inflammatory proteins more than 10 times higher than the common human flu virus H1N1. This might contribute to the unusual severity of the disease caused by H5N1 in humans. If and when an influenza pandemic arises from one of the currently circulating pre-pandemic strains of  Asian HPAI H5N1, the mortality rates for the resulting human adapted pandemic strain cannot be predicted with any confidence.

Seasonal influenza vaccination does not appear to protect against H5N1 infection. And there is no time for antiviral medications to work, as most deaths occurred just 24 hours after the onset of the disease. Therefore, if Asian HPAI H5N1 undergoes the mutations that allow transmission between humans, for now what we can do is keep the innate immunity activated using M8, trying to avoid the pro-inflammatory cytokine storm, responsible for the high mortality rate.
