Adenovirus is a non-enveloped virus with a double-stranded DNA genome that commonly causes respiratory illness. It infects epithelial cells and attaches via fiber structures to the CAR receptor. Early genes induce cell cycle progression while late genes carry out DNA replication and structural protein production. Adenovirus has various mechanisms to evade host immune responses and can integrate oncogenes leading to cell transformation. Papillomavirus infects epithelial cells and its E6 and E7 oncoproteins inactivate tumor suppressors p53 and pRb to cause proliferation. Certain types are strongly associated with cancers like cervical cancer. Polyomavirus has oncoproteins that similarly inactivate tumor suppressors and can
This presentation on Adenovirus was prepared and presented by me and my classmate.This topic generally comes under subject of virology. Hope you will find it helpful. Thank you.
Adenoviridae is a group of medium sized, non-enveloped, double stranded DNA viruses that replicate and produce disease in the eye and in the respiratory, gastrointestinal and urinary tracts;
Adenoviruses (members of the family Adenoviridae) are medium-sized (90–100 nm), nonenveloped (without an outer lipid bilayer) viruses with an icosahedral nucleocapsid containing a double-stranded DNA genome. Their name derives from their initial isolation from human adenoids in 1953.
The presentation includes disease, treatment and management.
Adenovirus belongs to the family Adenoviridae
This is a double stranded DNA virus
Does not possess an envelope
Adenovirus is icosahedral in shape
Thus not easily destroyed
It’s name is given as this virus is first isolated from the add noise
But this virus can affect several systems and cause several illnesses
Adenovirus affects respiratory system, gastrointestinal system, genitourinary system and the eye
So this virus has many serotypes

Largest viruses that infect vertebrates
Can be seen under light microscope
Poxvirus diseases are characterized by skin lesions – localized or generalized
Important diseases caused by poxviruses are-

Molluscum contagiosum
A picornavirus is a virus belonging to the family Picornaviridae, a family of viruses in the order Picornavirales. Vertebrates, including humans, serve as natural hosts. Picornaviruses are nonenveloped viruses that represent a large family of small, cytoplasmic, plus-strand RNA viruses with a 30-nm icosahedral capsid.
Bunyavirus, any virus belonging to the family Bunyaviridae. Bunyaviridae is a family of arthropod-borne or rodent-borne, spherical, enveloped RNA viruses. Bunyaviruses are responsible for a number of febrile diseases in humans and other vertebrates. They have either a rodent host or an arthropod vector and a vertebrate host.
This presentation contains 45 slides on general virology comprises of topics on viral classification, transmission, pathogenesis, viral cytopathic effect, stages of viral infections, antiviral drugs and viral vaccines. It also have a slide noting an outline of laboratory diagnosis of viral infection. This power point presentation was designed for medical students, nurses and academicians teaching virology and microbiology in medical universities, schools or colleges.

An overview of Inclusion body hepatitis-hydropericardium syndrome (IBH-HPS) a...Dr.Kedar Karki
IBH/HPS is an acute infectious disease characterized by typical hydropericardium, severe anaemia, necrotic hepatitis and high mortality. In natural outbreaks, the affected birds may not exhibit any clinical signs (Jaffery, 1988) except sudden heavy mortality (Ravikumar et al., 1997). Mortality rates in various outbreaks range from 15- 60% (Asrani et al., 1997).
This particular presentation includes slide on basic virology about rabies virus, pathogenesis of rabies and it's management specially emphasized on guide of pre and post exposure vaccination.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
