Why phytanic acid accumulation occurs in place of Phytanol coA in autosomal recessive disorder

Answers

Answer 1

The accumulation of phytanic acid in autosomal recessive disorders such as Refsum disease is due to a deficiency in the enzyme phytanoyl-CoA hydroxylase (PAHX), which is responsible for breaking down phytanic acid.

Normally, phytanic acid is metabolized by a series of enzymes that convert it into pristanic acid, which can then be further broken down and eliminated from the body. One of the early steps in this process involves the conversion of phytanic acid to phytanoyl-CoA by an enzyme called phytanoyl-CoA ligase.

In individuals with PAHX deficiency, however, the enzyme responsible for breaking down phytanoyl-CoA is missing or not functioning properly. As a result, phytanoyl-CoA accumulates in the body and is converted back into phytanic acid by reverse reaction. This leads to an accumulation of phytanic acid in the tissues, which can cause damage to the nervous system, heart, and other organs over time.

It should be noted that while phytanol is also involved in the metabolism of phytanic acid, its accumulation is not typically observed in PAHX deficiency. Instead, it is the accumulation of phytanoyl-CoA and subsequent conversion to phytanic acid that causes the characteristic symptoms of Refsum disease and other related disorders.

Papillary muscles are attached to the cusps of valves by thin, strong connective tissue strings called a. the interventricular septa. b. the interventricular sulcus c. the auricles. d. the chordae tendineae.

Answers

Papillary muscles are attached to the cusps of valves by thin, strong connective tissue strings called the chordae tendineae.

These muscles are specialized muscles located within the ventricles of the heart. They play a critical role in the proper functioning of the heart valves. The cusps or leaflets of the heart valves, such as the mitral and tricuspid valves, are connected to the papillary muscles by thin, strong connective tissue strings called the chordae tendineae.

The chordae tendineae act as anchor points, attaching the papillary muscles to the valve cusps. When the ventricles contract during systole, the papillary muscles also contract, exerting tension on the chordae tendineae. This tension prevents the valve cusps from being forced backward into the atria, ensuring the proper closure of the valves and preventing the backflow of blood.

The chordae tendineae are made of tough, fibrous tissue that provides strength and stability to the attachment between the papillary muscles and valve cusps. Their tensile strength allows them to withstand the forces exerted during the cardiac cycle.

The chordae tendineae are essential components of the heart's structure and function. Their connection between the papillary muscles and valve cusps helps maintain the integrity of the valves and facilitates proper blood flow through the heart.

Case Study 3: Janis has been diagnosed with Parkinson's disease about eight years ago, and is showing signs of dementia. She stays at home with her youngest son, Ian, who serves as her carer during weekends. On weekdays, Ian brings his mum to the facility as he has to go to work. You have been assigned to provide care services for Janis. Janis undergoes therapy at least twice a week, usually every Monday and Thursday. She has been observed to be cooperative with the therapist and care workers, and shows a light disposition.
One Monday, her son Ian requested if he could watch over while his mum undergoes therapy session as she is unwell. According to the organisation's policies, carers ofclients are only allowed to watch their patients outside the therapy room. While the therapy session is ongoing, you noticed that Ian is uneasy - he is pacing around the room and peeks into the therapy room's small window. After the therapy, the specialist reports that Janis is unusually quiet today. You leave her to his son, as the son requested that he talk with his mum.
A few minutes later, you see Ian storming out of the room, his face looking furious. You walk over to Janis to ask what happened. She is hesitant at first, but she tells you that her son is suggesting that she stays in the facility as he may not be able to watch after her anymore. His son also told her that he would be managing the house while she is away, thus, asking her to provide access to her bank accounts so he could also pay forher medications. Janis says that Ian probably got upset because she couldn't tell him the information for her accounts as she might be having memory lapses. Janis further tells you not to speak about this with anyone.
Janis returns home with his son that weekend but is not around the following week. His son tells you that his mum has become very ill and does not want to leave the house. He promises to bring her next week.
Janis is an 80-year old client in a Lotus Compassionate Care's respite care facility. She stares or nods when you talk with her. She also seemed to have lost weight.

_____ is suggestive of tissue breakdown and unmanaged
diabetes.

Answers

Glycosylated hemoglobin (HbA1c) is suggestive of tissue breakdown and unmanaged diabetes.

When blood glucose levels are persistently elevated over time, glucose molecules attach to hemoglobin in red blood cells. The degree of glycosylation reflects the average blood glucose levels over the preceding 2-3 months.

Elevated HbA1c levels are indicative of unmanaged diabetes and suggest inadequate blood sugar control. Consistently high HbA1c levels indicate that blood glucose levels have been chronically elevated, leading to various complications.

One of these complications is tissue breakdown, which can result from prolonged exposure to high glucose levels. Persistent hyperglycemia can lead to damage in small blood vessels, nerves, and organs throughout the body.

This can result in diabetic complications such as neuropathy, nephropathy, retinopathy, and impaired wound healing. Tissue breakdown can manifest as skin ulcers, slow healing of wounds, and increased susceptibility to infections.

Maternal and child health is an important public health issue because we have the opportunity to end preventable deaths among all women and children and to greatly improve their health and well-being.
On the light of this statement, answer the following questions (using both the national and global level comparative data): -
Explain the infant and under five mortality rates (definitions, statistics, causes)

Answers

Infant and under-five mortality rates refer to the number of deaths among children who are under the age of one and five years, respectively. The infant mortality rate is a key indicator of the well-being of a society. The under-five mortality rate indicates the overall mortality rate of children under the age of five.

In 2019, the global infant mortality rate was 28 deaths per 1000 live births, while the under-five mortality rate was 38 deaths per 1000 live births.

In comparison, the infant mortality rate in the United States was 5.7 per 1000 live births, and the under-five mortality rate was 6.7 per 1000 live births (UNICEF, 2020).

The leading causes of infant and under-five mortality are preventable diseases such as pneumonia, diarrhea, malaria, measles, and HIV/AIDS.

Other factors that contribute to infant and child mortality rates include inadequate access to clean water and sanitation, poor nutrition, inadequate healthcare services, and poverty.

Therefore, improving maternal and child health is critical to reducing infant and under-five mortality rates globally. This can be done through strategies such as improving access to healthcare services, promoting vaccination programs, increasing access to clean water and sanitation, and educating women and families on proper nutrition and child-rearing practices.

14. Which of the following does NOT increase blood pressure? a. b. Increased sodium uptake in kidneys stimulated by aldosterone Increased water uptake in kidneys stimulated by anti-diuretic hormone c. Signal of decreased thirst d. Vasoconstriction 15. Which of the following structures is part of the respiratory zone? a. Pharynx b. Larynx C. Trachea d. Alveoli solls produce?

Answers

The signal of decreased thirst does NOT increase blood pressure.

The alveoli are part of the respiratory zone.

Thirst is the body's way of signaling a need for fluid intake, typically in response to dehydration or increased salt levels in the body. When the body is dehydrated, it releases hormones that stimulate thirst and conserve water. However, the signal of decreased thirst does not increase blood pressure.

Blood pressure refers to the force exerted by circulating blood against the walls of blood vessels. It is influenced by various factors, including the volume of blood in the body, the elasticity of blood vessels, and the diameter of blood vessels.

Increased sodium uptake in the kidneys stimulated by aldosterone and increased water uptake in the kidneys stimulated by anti-diuretic hormone both play a role in regulating blood pressure. Aldosterone promotes the reabsorption of sodium by the kidneys, which increases the volume of blood in circulation, leading to an increase in blood pressure. Anti-diuretic hormone (ADH) helps the kidneys retain water, which also increases blood volume and subsequently raises blood pressure.

Vasoconstriction is another factor that increases blood pressure. It involves the narrowing of blood vessels, which leads to increased resistance against blood flow and consequently raises blood pressure.

On the other hand, the signal of decreased thirst does not directly impact blood pressure. It simply indicates that the body's fluid needs have been met or that there is no immediate need for additional fluid intake. While proper hydration is essential for overall health, the absence of thirst does not contribute to an increase in blood pressure.

The respiratory zone is the region of the respiratory system where gas exchange takes place. It consists of the structures directly involved in the exchange of oxygen and carbon dioxide with the bloodstream. Among the options provided, the alveoli are the structures that are part of the respiratory zone.

The alveoli are tiny, balloon-like sacs located at the ends of the respiratory bronchioles. They are surrounded by an extensive network of capillaries, where the actual exchange of gases occurs. Oxygen from the inhaled air diffuses across the thin walls of the alveoli and into the capillaries, while carbon dioxide moves in the opposite direction, from the capillaries into the alveoli, to be exhaled.

The pharynx, larynx, and trachea are part of the conducting zone of the respiratory system. They serve as passageways for air to travel from the nose or mouth down to the lungs but are not directly involved in gas exchange.

The pharynx is the common passage for both food and air, connecting the nasal and oral cavities to the larynx. The larynx, commonly known as the voice box, contains the vocal cords and helps produce sound. The trachea, also known as the windpipe, is a tube reinforced with cartilage rings that leads air from the larynx to the bronchi, which further divide into smaller bronchioles and eventually reach the alveoli.

In summary, the alveoli, with their thin walls and extensive capillary network, are the structures within the respiratory system that are directly involved in the exchange of gases and are part of the respiratory zone.

"Specialty Pediatric Nutrition for children with Autism :
Pediatric Conditions and Long Term Implications
Does the condition influence calorie and protein requirements?
Why or how?

Answers

Autism Spectrum Disorder (ASD) is a group of developmental disorders that affect communication, behavior, and socialization in children. These disorders can result in feeding problems that affect the children's ability to meet their nutritional needs adequately.

This can result in malnutrition and other negative outcomes for the children. Pediatric nutritionists can develop special diets to meet the nutritional requirements of children with autism and other pediatric conditions. These diets are designed to provide the nutrients that children with autism require and address their unique feeding challenges.

Children with autism have different energy and nutrient requirements than typically developing children. Some children with autism may consume a limited range of foods, which can lead to nutritional deficiencies. For this reason, special pediatric nutrition is required to meet their specific nutritional needs.

For instance, children with autism often exhibit sensory difficulties and may have a limited range of foods they are willing to eat. Many of them prefer bland and monotonous food, and some even have food aversions. Consequently, they may consume an inadequate amount of calories or macronutrients, such as protein and fat, and some vitamins and minerals.

Additionally, some children with autism may have gastrointestinal symptoms, which can result in gastrointestinal discomfort and malabsorption of nutrients. Nutritional deficiencies in vitamins and minerals, such as vitamin D, calcium, magnesium, and zinc, are prevalent in children with autism.

Moreover, some studies have shown that children with autism have high levels of oxidative stress, which can contribute to inflammation and other related diseases. Consequently, antioxidants, such as vitamins C and E and beta-carotene, may play a vital role in managing the condition and its related comorbidities.

In conclusion, children with autism require special pediatric nutrition that addresses their unique nutritional needs. Nutritional deficiencies are common in children with autism, and special attention should be given to their energy and nutrient requirements. Dietary interventions, such as the use of a specialized formula and multivitamin/mineral supplements, may help to address these nutritional challenges.

Answers

The first shunt is the Ductus arteriosus, a vessel between the pulmonary trunk and the aorta. The second shunt is the Foramen ovale, a hole in the interatrial septum.

In the fetal heart, there are two shunts that connect the right heart to the left heart. The first shunt is known as the ductus arteriosus, which is a small vessel located between the pulmonary trunk and the aorta. It allows blood to bypass the non-functioning fetal lungs. The second shunt is the foramen ovale, which is a hole located in the interatrial septum, allowing blood to pass directly from the right atrium to the left atrium. This shunt helps bypass the fetal lungs as well. After birth, these shunts typically close and transform into non-functional structures, with the ductus arteriosus becoming the ligamentum arteriosum and the foramen ovale closing to become the fossa ovalis.

e. Front of chess

Answers

The following parts of the body have the largest representation in the homunculus of the postcentral gyrus is Lips (Option C).

What is homunculus?

A homunculus is a neurological "map" of the human body. The homunculus is a representation of the body based on how the primary somatosensory cortex (postcentral gyrus) represents different body parts. The sensory neurons in different areas of the body project to specific regions of the postcentral gyrus, which results in homunculus mapping.

The homunculus is located in the postcentral gyrus, which is a region of the parietal lobe of the brain. The postcentral gyrus is responsible for processing somatosensory information, including touch, pressure, temperature, and pain from the body.

Thus, the correct option is C.

Higher voltages are required for external defibrillation than for internal defibrilation. This statement is alows the user to vary the oxygen concentration of pratory gas between 21% and 100% by ______

Answers

Higher voltages are required for external defibrillation than for internal defibrillation. This statement is true and the user to vary the oxygen concentration of preparatory gas between 21% and 100% by adjusting the fractional concentration of inspired oxygen (FIO2).

Explanation:

External defibrillation: External defibrillation is a technique that requires higher voltages than internal defibrillation. The external defibrillator paddles are placed on the patient's chest. The device sends an electrical shock to the heart through the paddles to re-establish a healthy heart rhythm.

Internal defibrillation: Internal defibrillation is a technique that is used less often than external defibrillation. Internal defibrillation is a procedure in which paddles are implanted within the patient's chest. These paddles release electricity, which is sent to the heart, and its rhythm is restored.

Adjusting fractional concentration of inspired oxygen (FIO2): The concentration of oxygen in the air we breathe is 21 percent. The fractional concentration of inspired oxygen (FIO2) can be adjusted between 21 percent and 100 percent by the user. The user can change the FIO2 concentration of the preparatory gas by adjusting it to the desired value (between 21 percent and 100 percent). Thus, the user can vary the oxygen concentration of the preparatory gas by adjusting the fractional concentration of inspired oxygen (FIO2).

Knowing the impact of acidosis and alkalosis on synaptic transmission, critically analyze the following statement: "Hyperventilation may lead to seizures in epileptic patients."

Answers

Acidosis and alkalosis both affect the synaptic transmission in the body. Acidosis is a condition that occurs when there is a higher concentration of hydrogen ions in the blood, making the blood more acidic.

On the other hand, alkalosis is a condition that occurs when there is a lower concentration of hydrogen ions in the blood, making the blood more alkaline.In response to the statement “Hyperventilation may lead to seizures in epileptic patients,” it is true that hyperventilation can trigger seizures in epileptic patients.

This is because hyperventilation causes the blood pH to increase, which leads to respiratory alkalosis.Respiratory alkalosis, which occurs due to hyperventilation, is a condition in which there is a lower concentration of carbon dioxide in the blood.

This leads to a decrease in the concentration of hydrogen ions in the blood, which increases the pH of the blood. This can cause the nervous system to become more excitable and can trigger seizures in epileptic patients.

The Pediatrician has ordered IM Penicillin G 10000 units per kg. The patient weight is 150 lbs. How many units is the ordering dose? Round to nearest thousand place.
Group of answer choices
a. 6,820 units
b. 7000 units
c. 682,000 units
d. 680,000 units

Answers

To determine the ordering dose of IM Penicillin G, we need to convert the patient's weight from pounds to kilograms.

Therefore, the correct answer is:

d. 680,000 units.

1 pound is approximately 0.4536 kilograms.

So, for a 150-pound patient:

150 lbs. * 0.4536 kg/lb. = 68.04 kg (rounded to two decimal places)

Now, we can calculate the ordering dose:

Ordering dose = 10,000 units/kg * 68.04 kg = 680,400 units

Rounding to the nearest thousandth place, the ordering dose of IM Penicillin G is approximately 680,000 units.

A. True
B. False

Answers

"The active transport of salt in the descending limb is responsible for the increase in concentration of tubular fluid." is false because the concentration of tubular fluid is decreased in the descending limb. So, option B is the correct answer.

Active transport: Active transport is the movement of substances from lower to higher concentration against the concentration gradient using the energy of ATP. Active transport is carried out by carrier proteins present in the cell membrane.

Salt concentration: The concentration of salt is higher in the renal medulla than in the renal cortex. The loop of Henle plays a major role in establishing a concentration gradient in the renal medulla. In the descending limb, water is reabsorbed by osmosis, while sodium and chloride ions are reabsorbed from the tubular fluid by passive transport.
