Answers

Answer:Objective: To determine the combined effect of oxygen level and glucose concentration on cell viability, ATP production, and matrix synthesis of temporomandibular joint (TMJ) disc cells.

Design: TMJ disc cells were isolated from pigs aged 6-8 months and cultured in a monolayer. Cell cultures were preconditioned for 48 h with 0, 1.5, 5, or 25 mM glucose DMEM under 1%, 5%, 10%, or 21% O2 level, respectively. The cell viability was measured using the WST-1 assay. ATP production was determined using the Luciferin-Luciferase assay. Collagen and proteoglycan synthesis were determined by measuring the incorporation of [2, 3-(3)H] proline and [(35)S] sulfate into the cells, respectively.

Results: TMJ disc cell viability significantly decreased (P < 0.0001) without glucose. With glucose present, decreased oxygen levels significantly increased viability (P < 0.0001), while a decrease in glucose concentration significantly decreased viability (P < 0.0001). With glucose present, decreasing oxygen levels significantly reduced ATP production (P < 0.0001) and matrix synthesis (P < 0.0001). A decreased glucose concentration significantly decreased collagen synthesis (P < 0.0001). The interaction between glucose and oxygen was significant in regards to cell viability (P < 0.0001), ATP production (P = 0.00015), and collagen (P = 0.0002) and proteoglycan synthesis (P < 0.0001).

Conclusions: Although both glucose and oxygen are important, glucose is the limiting nutrient for TMJ disc cell survival. At low oxygen levels, the production of ATP, collagen, and proteoglycan are severely inhibited. These results suggest that steeper nutrient gradients may exist in the TMJ disc and it may be vulnerable to pathological events that impede nutrient supply.

Explanation:

A country, Azania, has a population of 150 million of which 16 percent is under 16 years old and 18 percent is considered not be in labor force. If 95 million are employed, calculate (a) the employment rate and (b) the unemployment rate. Show all steps.

Answers

Answer:

Explanation:

Employement rate = employed people /total labor force * 100

total labor force = 100 - 18% of population not in labor force =  72  = 0.72 *150million = 108 =million

employment rate  = [tex]\frac{95}{108} *100 = 87.96%\\[/tex]

umployment rate = unemployed people /total labor force = 100 - 87,96 = 12.04%

Well the top three hardest are Diamond, Sapphire and Ruby, and an easy way to remember is: red-white & blue stones! The hardness of a gemstone is measured on its place on Mohs scale of hardness. 10 on Mohs scale being the hardest known naturally occurring substance– and the honor goes to the diamond

Although the hardest natural stone on the planet is a diamond that is rated ten on the Mohs scale, granite is known as the most durable and hardest natural stone that is used in construction material and is measured six on Mohs scale.

The hardest mineral commonly found in granite is quartz, which is normally a somewhat translucent, white to grey colored mineral.

(so from your options granite is the hardest to scratch )
