 glucose solution of density 1050 kg/m3 is transferred from a collapsible bag through a tube and syringe into the vein of a pers

on's arm. The pressure in the arm exceeds the atmospheric pressure by 1400 N/m2.
How high above the arm must the top of the liquid in the bottle be so that the pressure in the glucose solution at the needle exceeds the pressure of the blood in the arm? Ignore the pressure drop across the needle and tubing due to viscous forces.

Answer:

0.136 meter

Explanation:

The following equation will be used to solve this question -

P_{atm} + \frac{1}{2} (rho)v^2 + (rho)gh = P_{inject} + \frac{1}{2}(rho)v_{inject}^2 + (rho)gh_{injec}

P_{atm} -P_{injec} = 1400\frac{N}{m^{2} }

Velocity is zero.

Removing out the nullified terms from the above equation, we get -

(rho)gh = P_{injec}\\1050 * 9.8 * h = 1400\\h = \frac{1400}{1050*9.8} \\h = 0.136 meter

Hence,  top of the liquid in the bottle must be at a height of 0.136 meter.

Increased Serum Interleukin-2 Levels Are Associated with Abnormal Peripheral Blood Natural Killer Cell Levels in Patients with A
amm1812

In rheumatoid Arthritis patients, NK cell levels were abnormally elevated, possibly due to high serum levels of IL-2.

Rheumatoid arthritis (RA), is an autoimmune disease that means our own immune system attacks self healthy cells in the body by mistake, causing inflammation (painful swelling),mainly attacks the joints.

The given study is to investigate the relationship between serum interleukin-2 (IL-2) levels and disease activity.

This study also showed the relationship between absolute numbers of peripheral lymphocyte subsets, autoantibodies, and associated cytokines in patients with rheumatoid arthritis (RA).

The results showed that the number and percentage of NK cells were positively correlated with serum IL-2 levels so, IL-2 can be a reason for elevated level of NK cells
