Diseases of the Liver and Gallbladder01:26

Diseases of the Liver and Gallbladder

1.0K
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Microorganisms in Medicine and Therapeutics

397
Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

177
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

47.1K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Retroviruses

12.7K
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

Viral Recombination00:57

Viral Recombination

23.8K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Area of Science:

  • Hepatology and Viral Hepatitis Research
  • Immunology of Viral Infections
  • Global Public Health Initiatives

Background:

  • Six distinct hepatitis viruses (Hepatitis A, B, C, D, E, and G) impact patient and clinical management differently.
  • Extensive research has elucidated epidemiology, virology, and clinical/immunological histories of acute and chronic hepatitis infections.

Purpose of the Study:

  • To review current clinical information and guidelines for each hepatitis virus.
  • To synthesize recent research and discuss future directions for hepatitis virus management and elimination.

Main Methods:

  • Review of existing literature on hepatitis virus epidemiology, virology, and immunology.
  • Analysis of clinical data and host immune responses to viral hepatitis.
  • Synthesis of current organizational guidelines and recent research findings.

Main Results:

  • Development of vaccines for Hepatitis A, B, and E, and effective antivirals for Hepatitis B and C.
  • Significant progress in transforming hepatology, transplant medicine, and global health strategies.
  • Identification of barriers to the global elimination of chronic viral hepatitis.

Conclusions:

  • Therapeutic breakthroughs are revolutionizing hepatitis treatment and prevention.
  • An ambitious global effort is underway to eliminate chronic viral hepatitis.
  • Continued basic and clinical research is essential to overcome barriers and achieve hepatitis elimination goals.
