Non communicable diseases in most of the developing countries have surpassed the morbidity and mortality arising from communicable diseases. However there are people who continue to suffer from the residual disabilities of some communicable disease acquired at younger age like polio and develop non
A synthetic gene coding for the coat protein of tobacco mosaic virus (TMVCP) was expressed in E. coli under the direction of the lacUV5 promoter. Modification of the 3' end of the TMVCP gene by insertion of a region coding for an antigenic epitope from poliovirus type 3 resulted in the
The 1945 to 1961 period was characterised by a significant increase in the international scientific knowledge of the health risks of smoking. Despite this, there was relatively little response by the New Zealand Government, the New Zealand medical profession and other local agencies. Specific
One of the milestones of vaccinology is the depletion of the global impact of Poliomyelitis. The current vaccines to deal with Polio comprise the Sabin and Salk formulations. The main limitation of the former is the use of attenuated viruses that can revert into pathogenic forms, whereas the latter
Tobacco chewing is a widespread habit which leads to DNA damage. We are reporting a case of a tobacco chewer in which chromosomal aberrations, DNA breakage, buccal micronuclei and urinary thioether excretion level were studied. The study was carried out on a 28 year old male subject who is polio
DNA-peroxidase probes were synthesized according to a modified method (Renzetal) for the detection of lambda phage DNA (model system), polio, potato X and M, tobacco mosaic viral RNAs by spot hybridization onto nitrocellulose membranes. cDNAs (300-1400 bases) complementary to the viral RNAs were
The DNAase digestion end-product of calf thymus DNA contains oligonucleotides that will function as primers for the efficient transcription into DNA of many naturally-occurring RNA's by purified avian sarcoma virus RNA-directed DNA polymerase. The labeled DNA transcripts so obtained are valuable as
1. Inhibition of glucose utilization in homogenates of brains of mice infected with poliomyelitis virus (Lansing strain) is reported. The inhibition occurs with glucose, or fructose-6-phosphate as substrate. No inhibition occurs in the presence of hexosediphosphate. 2. Brain homogenates of mice
Factors that accelerate rates of 'normal' age-related cerebral atrophic and degenerative changes are important because they may predispose to cognitive declines. To determine characteristic patterns of normal aging, risk factors were correlated with serial neurological-neuropsychological
OBJECTIVE
To determine whether DTPP+Hib vaccination (diphtheria, tetanus, pertussis, poliomyelitis +/- haemophilus) increased the risk of sudden unexpected death (SUD) in children under 3 months of age.
METHODS
We conducted a multicentre case-control study in the 28 French 'SIDS Centers'. Case
The interactions between a causative agent and a susceptible host involve a series of responses most of which are subclinical or asymptomatic but a few of which are manifested by clinical illness. The factor(s) which tip the balance are poorly understood in both acute and chronic diseases. It is
The electrophoretic mobilities of ribosomal ribonucleic acids (RNA) from cultured mammalian (HeLa, Vero, MDBK), avian (chick embryo), and bacterial (Escherichia coli) cells, and RNA species extracted from selected viruses (Sindbis, polio, tobacco mosaic, Sendai) were compared, employing a simple,
There are many things that, as physicians, we universally take for granted. One does not need a background in medical statistics to understand that seat belts save lives and reduce injuries in car accidents. Nor do you need to have an epidemiology degree to know that tobacco smoking is causative for
The three antiviral vaccines discovered in the 18th century (smallpox), 19th century (rabies), and 20th century (polio) share a common feature: none would ever be licensed today for human vaccination. Yet Jenner's smallpox vaccine led to the eradication of smallpox, Pasteur's rabies vaccine
