Reticulocyte production index The reticulocyte production index, also called a corrected reticulocyte count, is a calculated value used in the diagnosis of anemia. This calculation is necessary because the raw reticulocyte count is misleading in anemic patients. The problem arises because the reticulocyte count is not really a count but rather a percentage: it reports the number of reticulocytes as a percentage of the number of red blood cells. In anemia, the patient's red blood cells are depleted, creating an erroneously el

Reticular Connective Tissue It has a network of reticular fibers, made of type III collagen. Reticular fibers are not unique to reticular connective tissue, but only in this type are they dominant. Reticular fibers are synthesized by special fibroblasts called reticular cells. The fibers are thin branching structures.

- Reticulated pythons are strictly carnivorous. They are most productive as ambush predators, often waiting in trees for unsuspecting prey (Murphy and Henderson 1997). They are also known to be active foragers, however this method of hunting is seldom used because of the amount of energy it requires.eographic Range. Reticulated pythons can be found throughout Southeast Asia. Their range includes the Nicobar Islands, Burma through Indochina, and Borneo, Sulawesi, Ceram and Timor in the Malay archipelago. (Murphy and Henderson, 1997).

Standard cubic foot A standard cubic foot is thus not a unit of volume but of quantity, and the conversion to quantity (scf to moles) is straight forward; a standard cubic foot represents 1.19804 moles (0.0026412 pound moles). However, converting between standard volumes is not always straightforward. standard cubic foot of gas is defined as a cubic foot at a temperature of 21 °C (70 °F) and a pressure of 101.35 kilopascals (14.696 psia).

Retinitis Pigmentosa Retinitis pigmentosa is an inherited condition which involves both eyes. If it starts in one eye, the other eye usually develops the same condition in a number of years. Most cases are familial, inherited in a variety of ways, including dominant, recessive, and sex-linked recessive.

Reticular Formation: Definition & Functions The reticular formation has two main components: the ascending and the descending reticular formation. The ascending reticular formation is responsible for sleep cycles and is also called reticular activating system. The descending reticular formation affects your posture and autonomic nervous system functioning. Certain nuclei are also responsible for eye movements, coughing, chewing, swallowing, and vomiting.

What is Livedo Reticularis? These 10 animal facts will amaze you. Livedo reticularis is a skin condition that causes skin discoloration in what is termed a “mottled” pattern. It may be either extremely benign or a symptom of more serious underlying conditions.fter all, livedo reticularis symptoms are caused by dilation of the blood vessels. The blood vessels dilate and then the blood pools and is visible through the skin. I'm pretty surprised that the cold can cause this, though. I always thought being cold caused blood vessels to constrict, not dilate.

Reticulocyte Count and Reticulocyte Hemoglobin Content The absolute reticulocyte count is the number of reticulocytes in a volume of blood, which is a marker of RBC production. Reticulocytes are immature, but already anucleated, erythroid cells (RBCs) with residual detectable amounts of RNA, thereby capable of producing hemoglobin despite anucleation.he automated hematology analyzer can also report a measurement of reticulocyte-specific hemoglobin content as mean reticulocyte hemoglobin content (CHr) or reticulocyte hemoglobin equivalent (Ret-He), depending on the type of instrument used.

Reticulated Python Care Tips The name “reticulated” means net-like, and it refers to the snake’s pattern of irregular, geometric markings on a contrasting background. The pattern and coloration has evolved, as it has in many animals, to allow them to be less conspicuous to potential predators and prey alike.y Bob Clark. In the last 20 years, there has been an evolution in the captive reticulated python (Python reticulatus reticulatus), certainly in the public perception, and in a physical sense, as well.

As its name implies, its most influential component is the reticular formation.inally, Magoun recorded potentials within the medial portion of the brain stem and discovered that auditory stimuli directly fired portions of the reticular activating system. Furthermore, single-shock stimulation of the sciatic nerve also activated the medial reticular formation, hypothalamus, and thalamus.

What is the function of Reticular Activating System? This system is considered the brain’s attention center. It is the key for switching on your brain and also considered as the main center of motivation. The Reticular activating system is connected to the spinal cord at its base from where it accepts information which comes from the ascending sensory tracts directly.rain has created our mind as the entity and every thought which peeps up in our mind has its thread located in the mastermind which is the brain. Reticular activating system is one of the most important parts of our brain that has great influence over cognition.

- The reticular activating system (RAS) is a part of the mammalian brain located in the brain stem. In human biology, it is believed to play a role in many important functions, including sleep and waking, behavioral motivation, breathing, and the beating of the heart.leep control is the domain of the reticular activating system. Trauma to the RAS area has been linked to narcolepsy. In some cases of reticular activating system damage, a coma may result.

Medical Dictionary A reticulocyte count is a blood test that measures how fast red blood cells called reticulocytes are made by the bone marrow and released into the blood. Reticulocytes are in the blood for about 2 days before developing into mature red blood cells. The reticulocyte count rises when there is a lot of blood loss or in certain diseases in which red blood cells are destroyed prematurely, such as hemolytic anemia.
