(a) To determine: The reason for smokers getting a severe cough The smoke of the cigarettes contains many harmful compounds like the acrolein, benzopyrene and 1,3-butadiene which are extremely harmful for lung cells and human body. These harmful compounds blocks or chokes the spaces of the alveoli as these molecules are of greater size than the pore size of the air sacs of alveoli. The walls of lungs are lines by the cells of mucosal lining so when the pores of the alveoli gets jammed by the compounds of cigarette then the smoker gets the severe cough. This is why the smokers get a severe cough. (b) To determine: The reason that non-smokers are less likely to get a chronic cough.

Summary Introduction

(a) To determine:The reason for smokers getting a severe cough

The smoke of the cigarettes contains many harmful compounds like the acrolein, benzopyrene and 1,3-butadiene which are extremely harmful for lung cells and human body. These harmful compounds blocks or chokes the spaces of the alveoli as these molecules are of greater size than the pore size of the air sacs of alveoli.

The walls of lungs are lines by the cells of mucosal lining so when the pores of the alveoli gets jammed by the compounds of cigarette then the smoker gets the severe cough. This is why the smokers get a severe cough.

(b) To determine:The reason that non-smokers are less likely to get a chronic cough.

Outline a method for using apomixis to maintain feminized CannabisAssume apomixis is controlled by a single dominant gene. You can choose the type of apomixis: obligate or facultative, gametophytic or sporophytic. Discuss advantages and disadvantages of your proposed method.

Kinetics: One-Compartment First-Order Absorption 1. In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple routes of administration provides greater insight than a single route of administration alone. The following data was collected in 250-g rats following bolus IV, oral (PO), and intraperitoneal (ip) administration. Using this data and set of graphs, determine:(calculate for each variable) (a) k, C0, V, and AUC* for the bolus iv data (b) k, ka, B1, and AUC* for the po data c) k, ka, B1, and AUC* for the ip data (d) relative bioavailability for po vs ip, Fpo/Fip (e)absolute ip bioavailability, Fip (f) absolute po bioavailability, Fpo

3. A promising new drug is being evaluated in human trials. Based on preliminary human tests, this drug is most effective when plasma levels exceed 30 mg/L. Measurements from preliminary tests indicate the following human pharmacokinetic parameter values: t1/2,elim = 4.6hr, t1/2,abs = 0.34hr, VD = 0.29 L/kg, Foral = 72%. Based on these parameters, estimate the following if a 49 kg woman were to receive a 1000mg oral dose of this drug: (a) Estimate the plasma concentration of the drug at 1hr, 6 hr, and 20hr after taking the drug ( Concentration estimate) (b) Estimate the time for maximum plasma concentration (tmax). (c) Estimate the maximum plasma concentration (Cmax). (d) Estimate the time at which the plasma level first rises above 30 mg/L. (Note this is a trial and error problem where you must guess a time, plug it into the concentration equation, and determine if it is close to 30 mg/L. Hint: based on part (a) it should be apparent that the answer is less than 1hr.) (e)…
