the wife's previous salpingo-oophorectomy and the husband's untreated cryptorchidism can lead to infertility due to anatomical and physiological factors affecting the transport of eggs and the production of healthy sperm.
In the given case, the couple is having fertility issues. The wife had a previous salpingo-oophorectomy on the left side, which is the removal of the fallopian tube and an ovary. On the other hand, the husband's past medical history indicates untreated cryptorchidism on the left side, which is the absence of one or both testes from the scrotum.
Both of these conditions can lead to infertility in couples. These two conditions have anatomical reasons that can cause infertility as follows: Anatomical reasons - The wife: The salpingo-oophorectomy on the left side of the wife can prevent the eggs from being transported to the uterus, making it difficult for fertilization to occur. This may lead to a blocked tube or the egg may fail to implant even if fertilization happens.
The husband: The cryptorchidism that the husband is experiencing may lead to a decrease in the number and quality of sperm produced. It can also result in the abnormal structure of the sperm produced and increase the temperature in the testes, leading to damage to the sperm. This can cause difficulty for the sperm to fertilize the egg due to the low quality or reduced quantity of sperm produced.
Physiological reasonsThe physiological causes of infertility are as follows: The wife: High levels of follicle-stimulating hormone (FSH) in the blood tests of the wife suggest that she has fewer eggs left in her ovaries. This condition is known as diminished ovarian reserve. It means that the number and quality of the eggs produced by the wife have decreased, which can cause infertility.
The husband: The high levels of FSH in his blood test of the husband suggest that his body is trying to produce sperm, but there is a problem with the production process. The low levels of testosterone also indicate a problem with the testicular function. It may lead to a decrease in sperm production, and the existing sperm may not function correctly. This can also cause infertility in men.

20 3 points PolyGigantus Pharmaceutical Company is holding clinical trials for a drug that hold tremendous promise for curing cancer. One of their scientists just discovered that this drug has the side effect of blocking the renal transport of alpha ketoglutarate. Explain why this is a problem for patients taking this drug. (Hint: the answer has nothing to do with cancer). Convince me you understand the underlying physiology. 21 2 points An increase in circulating aldosterone will have what effect on its target cells? Choose ALL that apply. Note: the term 'expression" means "synthesize and place in the membrane". a. decreased potassium excretion b. Increased potassium excretion c. Increased expression of SGLT in the apical membrane d. Increased expression of Na+/K+ ATPase in the basolateral membrane e. Increased excretion of H+
The apical membrane expression of sodium-glucose transporters (SGLT) is increased, leading to greater glucose reabsorption, and the basolateral membrane expression of Na+/K+ ATPase is also increased, which leads to greater sodium reabsorption and potassium excretion.
Answer to 20: Alpha-ketoglutarate is a vital molecule in the citric acid cycle, where it serves as an intermediate. PolyGigantus pharmaceutical company's clinical trial drug has the side effect of blocking the renal transport of alpha-ketoglutarate, which means it prevents alpha-ketoglutarate from being taken back up by renal tubular cells to the bloodstream. As a result, the amount of alpha-ketoglutarate in the blood decreases, affecting various body systems.The citric acid cycle is a metabolic pathway that converts food into usable energy, and alpha-ketoglutarate is a significant part of it. This pathway is required for the production of adenosine triphosphate (ATP), which provides energy to the cells. When alpha-ketoglutarate is blocked, it results in a lack of ATP, which can cause a lack of energy, leading to weakness and fatigue. The decrease in alpha-ketoglutarate in the blood can also affect the kidneys' function. If the alpha-ketoglutarate level is low, the kidneys' ability to excrete nitrogen waste decreases, leading to nitrogen accumulation in the blood and potentially causing damage to the brain and other vital organs. Additionally, because alpha-ketoglutarate is necessary for protein synthesis, a deficiency can result in muscle wasting and, in severe cases, neurodegeneration.
Answer to 21: The answer to this question is option a. Decreased potassium excretion and option c. Increased expression of SGLT in the apical membrane.Aldosterone is a hormone that is produced by the adrenal gland that controls electrolyte and fluid balance by regulating sodium and potassium in the blood. When aldosterone levels are elevated, the kidneys respond by retaining sodium and excreting potassium. Aldosterone works by binding to receptors in the kidney, causing cells to increase the expression of sodium-potassium channels and sodium-glucose transporters.

Did the viable counts for the three methods concur? What could have caused any discrepancies between the methods?
When carrying out colony counts from serial dilutions, why are plates with fewer than 30 colonies or greater than 300 colonies disregarded?
What are the advantages and disadvantages of using direct counting methods?
Which method, the Breed smear (refer to lecture notes / prac manual) or the haemocytometer, do you think would be more suitable to count cells which are motile?
The viable counts for the three methods may or may not concur depending on how the methods were executed, and what was the level of contamination in the sample.
The discrepancies between the methods may be due to many reasons like Accuracy of dilution: If the dilution of the bacterial culture is not made properly, it can give different counts on different plates of the same dilution, hence leading to inaccurate results in the counting of bacteria.
Air contamination: Air contamination can lead to the introduction of microorganisms to the environment, therefore affecting the total viable counts of the culture. It is important to use a sterile environment and handling techniques to avoid the issue.
The difference in culture conditions: If the three methods are performed under different conditions such as temperature, medium, or growth time, the outcome of the results will not be the same and the viable counts for each method will differ.
The plates with fewer than 30 colonies are disregarded because they are statistically unreliable and may lead to less accurate results. Conversely, the plates with more than 300 colonies are also not counted as they are too numerous and can merge together which can make counting difficult.
The advantages of direct counting methods include an Easy and straightforward way to obtain cell counts.Quantitative results were obtained in a short period of time.Suitable for high cell concentration samples.
Disadvantages of direct counting methods include: Motile cells can move around, making accurate counting difficult. The cells cannot be differentiated into dead and live cells under this method. Counting errors are more common as it is performed manually.
Hemocytometer would be a more suitable method to count cells that are motile. The Breed smear method would be unsuitable to count motile cells as the cells will not remain in the same position in the smear.

The observation that there is a limit to how many times a cell can divide is the basis for the Hayflick limit.
The concept of the Hayflick limit was first introduced in the 1960s by Leonard Hayflick and Paul Moorhead. They observed that normal human cells have a limited number of times that they can divide and that number was approximately 50 cell divisions or less. The Hayflick limit is the number of times a cell can divide before reaching senescence, which is also known as replicative senescence.
It has been suggested that the Hayflick limit is related to telomeres, which are the repetitive nucleotide sequences at the ends of chromosomes. With each cell division, telomeres become shorter. When telomeres become too short, they can no longer divide, which leads to senescence. The Hayflick limit has implications for aging and disease since it affects tissue renewal and regeneration. It has also been linked to cancer since cancer cells can divide indefinitely by bypassing the Hayflick limit.

The following statement concerning the transduction mechanism in vestibular hair cells is correct: "Deflection of the cupula such that stereocilia move toward the kinocilium causes the hair cell to depolarize."
The vestibular hair cells, also known as the hair cells of the inner ear, are mechanoreceptors that detect head movement and head orientation with respect to gravity. These cells are located in the vestibular organs, which are part of the inner ear. They are made up of two types of cells: type I and type II. Type I hair cells are flask-shaped cells with a single kinocilium, whereas type II hair cells are cylindrical-shaped cells with numerous stereocilia and a single kinocilium. The correct statement concerning the transduction mechanism in vestibular hair cells is that "deflection of the cupula such that stereocilia move toward the kinocilium causes the hair cell to depolarize.
"The stereocilia are tiny, hair-like structures that extend from the apical surface of the hair cells. The stereocilia are arranged in rows of increasing height, with the tallest stereocilium located next to the kinocilium. The hair cells' stereocilia are embedded in the overlying gelatinous layer called the cupula. The cupula is a viscous structure that deflects when the head is rotated, bending the stereocilia of the hair cells. The movement of the stereocilia in one direction (towards the kinocilium) results in the opening of ion channels, causing depolarization of the hair cells. As a result, the hair cells produce a receptor potential that excites the vestibular nerve fibers, which convey the signal to the brain.

Teacher comment:
Explanation of physiological mechanism needed. Please take your notes and refresh how high frequency stimuli increase force. Here you had to explain the calcium effect.
The force of contraction increases when repeated stimuli are given due to the physiological mechanism of high-frequency stimulation increasing the concentration of calcium ions, which leads to stronger muscle contractions.
The force of muscle contraction is regulated by the concentration of calcium ions in the muscle fibers. When a motor neuron stimulates a muscle fiber, it triggers the release of calcium ions from the sarcoplasmic reticulum within the muscle cell.
These calcium ions bind to specific sites on the contractile proteins, allowing for the formation of cross-bridges and the generation of force.
When repeated stimuli are given, such as high-frequency motor neuron action potentials, the concentration of calcium ions in the muscle fiber increases.
This occurs because each action potential triggers the release of additional calcium ions from the sarcoplasmic reticulum before the previous ones have been fully reabsorbed. As a result, the availability of calcium ions for cross-bridge formation and force generation is enhanced.
The increased concentration of calcium ions allows for greater interaction between the contractile proteins, leading to a stronger force of contraction.
This phenomenon is known as summation and is the result of compounding the forces generated by temporally overlapping contractions. As the firing rate of motor units increases, reaching its maximum, the quantity of force created by the muscle grows accordingly.
Therefore, the increased force of contraction in response to repeated stimuli is attributed to the higher concentration of calcium ions, which promotes stronger interactions between the contractile proteins and enhances muscle tension.

The cell membrane image below contains:
The purple tube is called the phospholipid bilayerThe blue round circles are called proteinsThe wavy strings in the middle are called cholesterol.The whole image shows a cell membrane. What are the functions?Phospholipid bilayer is the main structure of the cell membrane and is made up of two layers of phospholipids. The phospholipids are arranged so that their hydrophobic (water-hating) tails are facing each other and their hydrophilic (water-loving) heads are facing out. This arrangement creates a barrier that separates the inside of the cell from the outside environment.
Proteins are embedded in the phospholipid bilayer and perform a variety of functions, including transporting molecules into and out of the cell, signaling to other cells, and providing structural support.
Cholesterol is a lipid that is also embedded in the phospholipid bilayer. Cholesterol helps to keep the phospholipid bilayer fluid and prevents it from becoming too rigid.
The cell membrane is a thin, flexible barrier that surrounds all cells. It protects the cell from its surroundings and controls what enters and leaves the cell.

Cardiac output is not the same as stroke volume because B. cardiac output is the amount of blood ejected from both ventricles per minute and D. stroke volume is the amount of blood ejected from a ventricle per beat.
Stroke volume (SV) refers to the amount of blood ejected from a ventricle per beat. It is the volume of blood that the heart pumps out per beat, and it is determined by the difference between end-diastolic volume and end-systolic volume. Cardiac output (CO) is the amount of blood ejected from both ventricles per minute. It is calculated as the product of heart rate (HR) and stroke volume (SV), as follows:
CO = HR x SVTherefore, CO and SV are related but distinct measures of the volume of blood pumped by the heart.
Therefore, correct options are B. cardiac output is the amount of blood ejected from both ventricles per minute and D. stroke volume is the amount of blood ejected from a ventricle per beat.

Click or tap here to enter text.
If a patient developed a tumor in their hypothalamus that constantly produced GHIH, the levels of other hormones would decrease. This is because GHIH inhibits the secretion of growth hormone (GH) and thyroid-stimulating hormone (TSH) by the anterior pituitary gland. The resulting decrease in GH would lead to decreased insulin-like growth factor 1 (IGF-1) production in the liver.
In response to the drop in blood volume due to internal bleeding in a hiker, the hormone systems that would be activated include the renin-angiotensin-aldosterone system (RAAS) and the antidiuretic hormone (ADH) system. The kidneys contain the enzyme renin, which is released in response to decreased blood volume. Renin catalyzes the conversion of angiotensinogen to angiotensin I, which is converted to angiotensin II by the enzyme ACE (angiotensin-converting enzyme).
A 35-year-old woman with symptoms of increasing tenseness and irritability, poor sleep, weight loss, palpitations, and constant sweating may be diagnosed with hyperthyroidism. Treatment for hyperthyroidism may include medications to reduce thyroid hormone production or surgery to remove part or all of the thyroid gland.

With this Module, I wonder how all the processes of forming an embryo who is in vitro got to go for, I wonder if it takes more time and if the person can choose the sex, and the day to be born or if a person can choose the color of eyes, or skin... any thoughts?
In vitro fertilization (IVF) involves multiple steps to form an embryo outside the body. It doesn't currently allow for choosing the day of birth, eye, or skin color, but preimplantation genetic testing can help identify genetic disorders.
In vitro fertilization (IVF) is a complex reproductive technology that involves several steps. It begins with the extraction of eggs from the woman's ovaries and the retrieval of sperm from the man. The eggs and sperm are then combined in a laboratory dish for fertilization, forming embryos. After a few days of development, one or more embryos are transferred into the woman's uterus for implantation.
Currently, IVF does not offer the ability to choose the day of birth, eye or skin color. These characteristics are determined by the genetic makeup of the parents and the natural processes of embryonic development. However, preimplantation genetic testing (PGT) can be performed on embryos before implantation to identify certain genetic disorders or chromosomal abnormalities.
PGT allows for the selection of embryos without specific genetic disorders but does not extend to selecting non-medical traits like eye or skin color. The technology and ethical considerations surrounding genetic selection are subject to ongoing discussions and regulations. It's essential to consult with healthcare professionals and fertility specialists for accurate and up-to-date information on the capabilities and limitations of IVF and reproductive technologies.
