Tuesday, August 30, 2016 Chapter 1 Major Issues • demographic shifts in balance of young vs. old - not limited to US (generation X/ baby boomers exceed millennials) • implications for our culture - interpersonally/psychosocially: perceptions of majority/minority group -politically/economically: social security, medicare • microaggression: demeaning; not paying attention to someone or failing to treat them like a human being • normal/primary: successful aging(biology) • secondary/pathological: lifestyle, able to control it - distinctions between the two above are difficult to make • tertiary aging: distance from death rather than distance from birth - rectangular aging curve *co-morbidity: multiple problems (heart disease, diabetes) 1 Tuesday, August 30, 2016 Aging Scale optimal(good)—> normal/primary(average)—>secondary/pathilogical(bad) • rectangular aging curve: this says that someone ages perfectly and dies only when their biological clock runs out; it is a continuous line for healthy aging(no decline) and then a straight drop off for death; this type of aging is highly unlikely - usually, the line looks more like stairs because people age slowly and quickly at certain points in their lives because of different experiences • normal aging - inter individual differences: fan effect; differences between people - intra individual differences: differences in one person overtime - fan effect generational stereotypes • - stereotypes: generalizations, can be positive or negative - most ageism is linked to greater involvement in risky behavior among younger adults - nobody is immune to stereotyping - generational differences emphasized over similarities empathy vs. perception of separateness: being aware of other peoples value systems 2 Tuesday, August 30, 2016 • Person-Environment Context (P-E-Fit): allows us to understand aging in context - people who are skilled are not stimulated enough in a bad environment - people who are not skilled can get too overwhelmed in a bad environment - you have to find the environment that fits with that person 3 Thursday, Sept. 1, 2016 Fat Cells • Fat Chance by Robert Lustig - MD (medical doctor) *DO: doctors who use more alternative methods - pediatric endocrinologist (hormones and glands) • doctors are under the control of: - pharmaceutical companies - insurance companies - government • adipose tissue: fat tissue • adipocytes: fat cells fat cells stage 1: cells are depending on one artery for blood supply - contains M2 macrophages; not activated because there is no debris to pick up/eat fat cells stage 2: hypertrophy: fat cells get bigger, increase in macrophages - contains M2 macrophages and M1 macrophages: pick up/eat debris fat cells stage 3: apoptosis: programmed cell death (if cell gets too stressed out) to protect healthy cells; sends out warning signals, MCF-1 attracts macrophages - contains M1 macrophages to clean up dead or dying cells 1 Thursday, Sept. 1, 2016 Sugar Metabolism • fructose - comes from nature - cheap to make • HFCS: sugar from corn • excess sugar: - liver handles it (largest organ in visceral cavity) - handles glucose metabolism - sends sugar into bloodstream for energy ATP - mitochondria makes ATP; packages glucose molecules as glycogen (100g) - stored in skeletal muscles (600g) lasting approximately 1.5 days - carbs (glucose) become fat in the liver; plastic fat: saturated fat (fatty acids) - triglyceride: backbone with 3 fatty acids attached to it - packed in VLDL(very low density) molecule—>turns into LDL after it dumps its load into the cell - has to be taken apart to go into a fat cell - starts secreting pro-inflammatory cytokines(go everywhere) - this can cause heart disease 2 Thursday, Sept. 1, 2016 Peristalsis: muscular movement of food ex: sugar oral cavity(sugar starts being digested by amylase)—> esophagus(smooth muscle) (longitudinal and circular muscles)—> sphincter(prevents stomach contents from coming up out of stomach)—> stomach—> sphincter—> small intestine (sugar is now glucose)(glucose goes through intestinal wall into blood stream)—> pancreas( secretes digestive juices in stomach, secretes insulin-beta cells) Diabetes • Type :l inheritable, can’t make insulin • Type l:linsulin resistant; insulin doesn’t work well, cells become resistant to insulin (primarily due to lifestyle) • Type ll:lbrain cells become resistant to insulin (leads to dementia); cells that control cognition have been starved of glucose *diabetes is usually not diagnosed until approximately 28 years of age 3
