  • We now recognize that human cancers evolve in an environment of metabolic stress. Rapidly proliferating tumor cells deprived of adequate oxygen, nutrients, hormones and growth factors up-regulate pathways that address these deficiencies to overcome hypoxia (HIF), vascular insufficiency (VEGF), growth factor deprivation (EGFR, HER2) and the loss of hormonal support (ER, PR, AR) all to enhance survival and proliferation

  • The results suggest that breast cancer could be preceded by systemic subclinical disturbances in glucose-insulin homeostasis characterized by mild, likely asymptomatic, IEM-like biochemical changes

  • The process would include variable periods of hyperinsulinemia with the consequent systemic MYC activation of glycolysis, glutaminolysis, structural lipidogenesis and further exacerbation of hypoglycemia, the result of MYC's known role as an inhibitor of liver gluconeogenesis
  • The metabolic changes we describe in breast cancer arise in concert with IEM-like changes in oxidative phosphorylation as detected by increased values of the ratio lactate/pyruvate (Supplementary Table 2A, 2B) characteristic of Ox/Phos deficiency [25]. In our study, 76% (70/92) of the European breast cancer patients had lactate/pyruvate ratios values higher than the normal value of 25.8
  • four-fold higher frequency of cancer (including breast) in patients with energy metabolism disorders
  • growing recognition that cancer cells differ from their normal counterparts in their use of nutrients, synthesis of biomolecules and generation of energy

  • blood concentrations of aspartate (p = 1.7e-67, FDR = 8.3e-67) (Figure ​(Figure1E)1E) and glutamate (p = 6.4e-96, FDR = 6.2e-95) (Figure ​(Figure1F)1F) were nearly 10 fold higher than the normal ranges of 0–5 μM/L and 40 μM/L, respectively
  • glutamine consumption associated with parallel increases in glutamate and aspartate (Figure ​(Figure1A1A red arrows) is considered a hallmark of MYC-driven “glutaminolysis”
  • Gln/Glu ratio inversely correlates with i- late stage metabolic syndrome and with ii- increased chance of death
  • changes in glutamine consumption, reflected by the Gln/Glu ratio could provide a metabolic link between breast cancer initiation and diabetes, reflective of a systemic metabolic reprogramming from glucose to glutamine as the preferred source of precursors for biosynthetic reactions and cellular energy
  • lower Gln/Glu ratios inversely correlated with insulin resistance and the risk of diabetes
  • the metabolic dependencies of cancer characterized by excessive glycolysis, glutaminolysis and malignant lipidogenesis, previously considered a consequence of local tumor DNA aberration [23] could, instead, represent a systemic biochemical aberration that predates and very likely promotes tumorigenesis
  • these metabolic disturbances would be expected to remain extant after therapeutic interventions

  • adipose tissue macrophage (ATM)
  • well-known regulators of lipid metabolism and mitochondrial activity
  • increasing adiposity results in a shift in the inflammatory profile of ATMs as a whole from an M2 state to one in which classical M1 proinflammatory signals predominate (21–23).
  • The M2 activation state is intrinsically linked to the activity of PPARδ and PPARγ
  • Physiologic enhancement of the M2 pathways (e.g., eosinophil recruitment in parasitic infection) also appears to be capable of reducing metainflammation and improving insulin sensitivity (27).
  • Independent of obesity, hypothalamic inflammation can impair insulin release from β cells, impair peripheral insulin action, and potentiate hypertension (63–65).
  • inflammation in pancreatic islets can reduce insulin secretion and trigger β cell apoptosis leading to decreased islet mass, critical events in the progression to diabetes (33, 34)

  • The testes of probiotic-fed aged mice were rescued from both seminiferous tubule atrophy and interstitial Leydig cell area reduction typical of the normal aging process. Preservation of testicular architecture despite advanced age or high-fat diet coincided with remarkably high levels of circulating testosterone.

    Reclining wheelchairs, since the product class is built around one key feature: the capability to adjust the backrest and/or footrest into a reclined position. This feature is especially important to users who find it difficult or impossible to sit in a fully upright position, and users who sleep in their chairs frequently. For those that are looking for a more portable chair. When compared with a similar, non-reclining chair, a reclining wheelchair tends to weigh more and - unlike other manual models - manual wheelchairs that recline typically aren't foldable. reclining wheelchair compensates mechanically for body positioning by automatically readjusting armrests and lateral supports.

    Recliner wheelchair is low profile allowing to comfortably fit under tables and desks. Enjoy numerous activities with increased comfort such as stretching, napping and watching television. The ability to recline also improves circulation and the ability for sore spots to heal.

    Cerebral palsy (CP) is a group of conditions caused by medical abnormalities in the development of a fetus or the early life of a child. These lead to damage or delayed development in the brain. The disorder is permanent and, though it does not worsen with age, the level of functionality of a person with cerebral palsy varies widely: in some cases, effects may be very minor, while in others, movement is impaired to the extent that a wheelchair is required. Common complications associated with CP vary by the type of CP disorder but can include vision problems, seizures, learning disabilities, and issues speaking, writing, and performing other tasks. Cerebral palsy causes problems with muscle tone, movement, balance and/or coordination. Symptoms and effects range from mild to severe. In some infants, problems are evident soon after birth. In others, diagnosis comes in later infancy or toddlerhood. Cerebral Palsy Wheelchair Description: The model designed for cerebral palsy child only. Ultra light weight aluminium alloy frame.

  • physicians should be aware of this drug-nutrient interaction and be vigilant to the possibility that statin drugs may, in some cases, impair skeletal muscle and myocardial bioenergetics.
