Loss of Tumor Suppressor Gene Functions01:12

Loss of Tumor Suppressor Gene Functions

6.1K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

Functional Brain Systems: Limbic System

7.3K
The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep brain...

Higher Mental Functions of the Brain: Language

3.8K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Higher Mental Functions of Brain: Learning and Memory

2.1K
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

Functional Brain Systems: Reticular Formation01:13

Functional Brain Systems: Reticular Formation

4.9K
The reticular formation is a complex network of gray and white matter located within the brainstem extending from the medulla to the midbrain.
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...

Drug Dosing: Infants and Children

295
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Area of Science:

  • Pediatric neuro-oncology
  • Ophthalmology
  • Neuroscience

Background:

  • Primary brain tumors in children can impact vision through various mechanisms.
  • Vision deficits may arise from direct involvement of afferent visual pathways or secondary effects like papilledema.
  • Consequences such as strabismus and cranial nerve palsies can also occur.

Purpose of the Study:

  • To review recent advancements in understanding how primary brain tumors affect vision in pediatric patients.
  • To highlight the importance of early ophthalmological assessment and intervention.

Main Methods:

  • Systematic review of literature on pediatric brain tumors and visual pathway involvement.
  • Discussion of recent findings in imaging techniques for quantifying visual pathway damage.
  • Emphasis on clinical monitoring and management strategies for vision loss.

Main Results:

  • Children with brain tumors face risks of vision loss, amblyopia, strabismus, and cranial nerve palsies.
  • Vision deficits may manifest years after primary tumor treatment.
  • Advanced imaging allows objective quantification of visual pathway damage.

Conclusions:

  • Early and systematic ophthalmological referrals are essential for children with primary brain tumors.
  • Proactive monitoring and treatment can significantly improve visual outcomes and quality of life.
  • Integration of ophthalmological care into neuro-oncology treatment plans is vital.
