Hyperechromic shift refers to an increase in staining intensity or color, often seen in abnormal cells with increased DNA content. Hypochromic shift, on the other hand, refers to a decrease in staining intensity, typically seen in cells with reduced hemoglobin content, such as in certain types of anemia.

What is hyperchromic and hypochromic effect?
In reference to the melting of DNA: as DNA melts (denatures from a double-stranded molecule to two single strands) the UV absorbance INCREASES. This absorbance increase is referred to as a "hyperchromic shift" or the hyperchromic effect. Thinking about this situation in reverse: the UV absorbance DECREASES as two DNA strands anneal to form double stranded DNA. This is referred to as the "hypochromic effect". (Please note, there is an answer on answers.com that incorrectly states the opposite, that absorbance decreases with melting. This is incorrect. Two single strands of DNA have higher absorbance than the double-stranded molecule.)
How can one distinguish between E and Z isomers using NMR spectroscopy?
In NMR spectroscopy, E and Z isomers can be distinguished by looking at the chemical shifts of the protons on the double bond. The protons on the double bond in the E isomer will have different chemical shifts compared to the protons on the double bond in the Z isomer. By analyzing these chemical shifts, one can determine whether a compound is in the E or Z configuration.
What are the factors that influence the accuracy of chemical shifts for NMR spectroscopy?
The factors that influence the accuracy of chemical shifts in NMR spectroscopy include the chemical environment of the nucleus, the strength of the magnetic field, the presence of nearby atoms or functional groups, and the temperature of the sample.
What is a control that minimizes unsuitable pH shifts is what?
A buffer solution is a control that minimizes unsuitable pH shifts. It helps to maintain a stable pH by resisting changes when acids or bases are added to the solution. Buffers typically consist of a weak acid and its conjugate base or a weak base and its conjugate acid.
What does Le Châtelier's principle say about upsetting a system at equilibrium?
When a change is imposed on a system at equilibrium, the "position" of the equilibrium shifts in a direction that reduces the effects of that change. For example, if a reactant or product is added, the system shifts AWAY FROM that added component to use the excess up. If heat is added, the system shifts AWAY FROM that added energy energy to use the excess up. If the pressure on a system is increased, the system shifts toward the side with fewer gas molecules.
Which anemia is also called hypochromic anemia?
Iron-deficiency anemia
What is if MCV and mch are low in blood test?
microcytic hypochromic anaemia
What is hypochromic microcytes?
Microcytic hypochromic anemia is a condition where the red blood cell count and hemoglobin levels are low (hence anemia), with small red blood cells (microcytic), and red blood cells that stain less intensely than normal (hypochromic). The most common cause is iron deficiency. Low levels of iron in the body.
What is hypochromic and what can it indicate?
Hypochromic refers to red blood cells that have a reduced amount of hemoglobin, resulting in a paler color. This can indicate anemia, a condition where the body does not have enough red blood cells or hemoglobin to carry sufficient oxygen to tissues.
What is microcytic hypochromic anemia?
Microcytic hypochromic anemia is a condition where the red blood cell count and hemoglobin levels are low (hence anemia), with small red blood cells (microcytic), and red blood cells that stain less intensely than normal (hypochromic). The most common cause is iron deficiency. Low levels of iron in the body.
What is hypochromicshift?
Hypochromic shift is observed in UV VISIBLE spectroscopy. This is the shift where the intensity of the absorption maxima is decreased
What is the diagnosis of a patient with raised ESR and hypochromic microcytic anemia and thrombocytosis and neutrophilia and pleural effusion?
Lupus erythematosus systemicus
What are some medical terms with the prefix Hypo?
Hypodermic, hypochondria, hypothryroidism, hypoandrogenism, hypoestrogenic, hypochromic are medical terms with the prefix hypo-.
What is a lack of hemoglobin?
Hypochromia (as in hypochromic anemia) is the medical term meaning deficiency in hemoglobin.
When the production function shifts upward?
MC shifts downward.
When was Sun Shifts created?
Sun Shifts was created in 2007.
How do the microcytic hypochromic anemia cells look like?
i have been having iron tabs for the last 10 months and have been told i have microcytosis what is the treatment and how has this problem happened
