Summary Introduction

To review:

The experimental design to test the hypothesis that the cuticle of parasitic nematodes provides the protection from the acids and enzymes when reach in the digestive system of the host.

Introduction:

The nematodes are enclosed in an exoskeleton which is known as cuticle. The presence of cuticle is the structural key for the success and diversity of nematode species. The outermost layer of the cells in nematodes is covered from a complex extracellular matrix (cuticle). Cuticle plays an important role in maintaining the body shape, movement and functions as the primary interface with the outer environment. The cuticle helps in protection from the host digestive system.

Summary Introduction

To review:

The detailed plan for altering the plant’s growth and reproductive characteristics.

Introduction:

Plant breeders play key role by focusing on desirable traits with great potential to increase plant yield. Hence, new technologies must be developed to accelerate breeding through improving genotyping and phenotyping methods and by increasing the genetic diversity in breeding germplasm. Marker Assisted Selection (MAS) is a marker technology used for specific phenotype chromosomal banding, a particular DNA or RNA motif, or a chemical tag that associates with the desired trait.

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)…
