We currently believe that instead of “antioxidants,” it is more appropriate to develop “modulators of oxidative stress” because, depending on the condition, it could be more beneficial to reduce or increase the oxidative stress.
Oxidative stress occurs due to increase ROS production during influenza virus infection, while the virus-induced oxidative stress may contribute to several aspects of pathogenesis of influenza virus infection, including tissue damage, inflammatory response, and apoptosis.
Oxidative stress is implicated as a pathogenic factor in a number of viral infections.
An inactivated vaccine (or killed vaccine) is a vaccine consisting of virus particles, bacteria, or other pathogens that have been grown in culture and then lose disease producing capacity.
Oxidative stress plays an important role in the degeneration of dopaminergic neurons in Parkinson's disease (PD). Disruptions in the physiologic maintenance of the redox potential in neurons interfere with several biological processes, ultimately leading to cell death.
Intracranial hypertension (IH) is a build-up of pressure around the brain.
High altitude is the most intriguing natural laboratory to study human physiological response to hypoxic conditions. In this study, we investigated changes in reactive oxygen species (ROS) and oxidative stress biomarkers during exposure to hypobaric hypoxia in 16 lowlanders.
Moreover, we looked at the potential relationship between ROS related cellular damage and optic nerve sheath diameter (ONSD) as an indirect measurement of intracranial pressure.
Elevated ICP is a major and common complication of meningitis irrespective of the offending pathogen.
A major concern associated with intracranial injuries is the management of intracranial pressure (ICP), a resulting factor of a TBI which facilitates into intracranial hematoma and/or cerebral edema.
These conditions have adverse effects on one’s brain, and the immediate management and relief of intracranial pressure are crucial in avoiding hydrocephalus and brain herniation, conditions which lead to sensory loss and even death.
Intracranial hypertension (IH) is a build-up of pressure around the brain. It can happen suddenly, for example, as the result of a severe head injury, stroke or brain abscess. This is known as acute IH. It can also be a persistent, long-lasting problem, known as chronic IH.
An increase in intracranial pressure is a serious and life-threatening medical problem. The pressure can damage the brain or spinal cord by pressing on important structures and by restricting blood flow into the brain.
Pedophilia can arise after brain damage, mainly involving. the frontal lobe [1, 2].
Common viruses This form of encephalitis usually affects the temporal lobe, the part of the brain that controls memory and speech. It can also affect the frontal lobe, the part that controls emotions and behavior.
Encephalitis caused by herpes is dangerous and can lead to severe brain damage and death.
Encephalitis is most commonly due to viruses, such as herpes simplex, herpes zoster, cytomegalovirus, or West Nile virus. It can occur in the following ways:
A virus directly infects the brain. A virus that caused an infection in the past becomes reactivated and directly damages the brain.
Reactivation is the mechanism whereby a latent virus that has infected a host cell switches to a lytic stage, undergoing productive viral replication and allowing the virus to spread.
Viral reactivation is associated with several stress factors [1], including viral infection (with other viruses), nerve trauma, physiologic and physical changes (e.g., fever, menstruation and exposure to sunlight) and immunosuppression (as in cytomegalovirus [CMV] disease).

The CMV promoter is commonly included in vectors used in genetic engineering work conducted in mammalian cells, as it is a strong promoter and drives constitutive expression of genes under its control.
The Laboratory of Animal and Plant Pathology at The Rockefeller Institute for Medical Research was in the forefront of research in virology, and principal investigator Louis O.
Kunkel had elucidated nearly every aspect of the biology and pathology of the various mosaic virus diseases.
Two scientists contributed to the discovery of the first virus, Tobacco mosaic virus.
In 1935 tobacco mosaic virus became the first virus to be crystallized; in 1955 the poliomyelitis virus was crystallized.
An automated procedure was developed to determine the geometrical and chemical interactions of crystalline virus particles using the crystal parameters, particle position, orientation, and atomic coordinates for an icosahedral asymmetric unit.
By Vangie Beal. Abbreviation for terahertz. A unit of measurement of frequency, also known as cycles per second. One TeraHertz (THz) is equal to 1012 (10 to the power of 12)hertz (Hz) or one thousand gigahertz (GHz). See also Hz.
Researchers from Hiroshima University and National Institute of Information and Communications Technology in Japan have announced the development of a terahertz (THz) transmitter
@Light2020To In this study, ultrasound-mediated cavitation of microbubbles was investigated as a mean of enhancing the delivery of a liposome designed for chemo-radionuclide therapy targeted to EGFR overexpressing cancer.
@Light2020To Method: Liposomes (111In-EGF-LP-Dox) were prepared by encapsulation of doxorubicin (Dox) and surface functionalisation with Indium-111 tagged epidermal growth factor.
The nature of man on Earth was formed after the nature of things in Heaven, and man had all things contained as potential within
himself, except divine life.
But he was as yet an untrained, undisciplined child, still nurtured simply upon the comforting bosom of Earth.
