Glomerular filtration rate (GFR) is the volume of fluid filtered from the renal (kidney) glomerular capillaries into the Bowman's capsule per unit time. [4] Central to the physiologic maintenance of GFR is the differential basal tone of the afferent (input) and efferent (output) arterioles (see diagram).
The estimated glomerular filtration rate (eGFR) is a measure of kidney function. [6] Adding a race adjustment to kidney algorithms results in higher eGFR values in people identified as black. [7] [8] [9] Reasons for this vary, but it is thought to partially stem from the notion that Black persons are more muscular. [8]
T790M, also known as Thr790Met, is a gatekeeper mutation of the epidermal growth factor receptor (EGFR). The mutation substitutes a threonine (T) with a methionine (M) at position 790 of exon 20, [ 1 ] affecting the ATP binding pocket of the EGFR kinase domain.
Hypocalcemia results from 1,25 dihydroxyvitamin D 3 deficiency (caused by high FGF-23 and reduced kidney mass) [30] and the skeletal resistance to the calcemic action of parathyroid hormone. [31] Osteocytes are responsible for the increased production of FGF-23, which is a potent inhibitor of the enzyme 1-alpha-hydroxylase (responsible for the ...
EGFR may refer to: Epidermal growth factor receptor (EGFR), a transmembrane receptor protein in humans Estimated glomerular filtration rate (eGFR), a measure of renal function
Mutations that lead to EGFR overexpression (known as upregulation or amplification) have been associated with a number of cancers, including adenocarcinoma of the lung (40% of cases), anal cancers, [18] glioblastoma (50%) and epithelian tumors of the head and neck (80–100%). [19]
Both studies find that aerobic fitness levels do not improve the predictive power of fat free mass for resting metabolic rate. However, recent research from the Journal of Applied Physiology, published in 2012, [33] compared resistance training and aerobic training on body mass and fat mass in overweight adults (STRRIDE AT/RT). When time ...
A pre-planned sub-group analyses showed that progression-free survival (PFS) was significantly longer for gefitinib than chemotherapy in patients with EGFR mutation positive tumours (HR 0.48, 95 per cent CI 0.36 to 0.64, p less than 0.0001), and significantly longer for chemotherapy than gefitinib in patients with EGFR mutation negative tumours ...
