18
Q

Benefit of intermittent fasting/ketogenic diet for mitochondrial dysfunction

A

increases insulin sensitivity
reduces insulin and leptin
increases mobilizations of FAs
increases BDNF

19
Q

5 common clinical presentations with mitochondrial dysfunction

A
Fatigue
Headaches
Chronic Pain
MCI/dementia
Depression
20
Q

how do heavy metals mess with mito function?

A

interfere with heme production

21
Q

how do organophosphates mess with mito function?

A

decreased NADH, succinate cytochrome c reductase, decreased CcOX activity, reduction of mitochondrial membrane potential, decreased ATP, increased ADP/ATP, LDH release, apoptosis

22
Q

how do organophosphates and organochlorides mess with mito function?

A

increase ROS damage, increase G6PD activity (impairing glucose metabolism), induce CYP450

23
Q

Protein that is master regulator of mitochondrial biogenesis and energy homeostasis

A

PGC-1 alpha

24
Q

Which organs have greatest energy use and demands?

A
Brain (1)
Muscle (2)
Liver
Heart
Kidney
Adipose
25
Q

28
Q

peripheral fatigue

A

physical capacity and performance ability
measured by gait, strength, endurance
energy depletion - low ATP, depleted by glycogen, reduced pyruvate, malnutrition
metabolic by products - lactate and H due to glycogen breakdown, ammonia due to aa breakdown
dehydration - cardiac output and increased thermal strain

29
Q

central fatigue

A

psychic, perceived effort
governed by neural networks, neurotransmitters, emotions, thoughts
measured via TEA - task effort and awareness

30
Q

Fatigue triggers

A

travel (infections), ticks, sex (HIV, Hep C), sedentary, poor sleep, EBV, vial, HMB (anemia), DM, thyroid dz, heavy metal toxicity
