Antimicrobial susceptibility testing was performed to screen a novel compound. The MIC was found to be 10ng/mL. Use the following data to determine the percent recovery for each treatment group. What is the MBC and would you describe the antimicrobial tested as static or cidal?
Novel compound concentration CFU/mL Present Recovery
0ng mL 3.4 x 10^5
10ng/mL 2.4 x 10^5
20ng/mL 6.4 x 10^4
40ng/mL 1.4 x 10^4
80n mL 4.4 x 10^3
160n mL 0
Answer:
a) Percent recovery
100%, 70.58%, 4.11%, 1.29% , 0%
b) MBC = 160 ng mL
c) Static
Explanation:
A) Calculate the percent recovery for each group
i) for 0ng mL
( 3.4*10^5 / 3.4*10^5 ) * 100 = 100%
ii) for 10ng mL
( (2.4 * 10^5) / (3.4 * 10^5) ) * 100 = 70.58%
iii) for 20ng mL
( ( 6.4 * 10^5 ) / ( 3.4 * 10^5 ) ) * 100 = Nil
iv) for 40 ng mL
( ( 1.4 * 10^4 ) / ( 3.4 * 10^5 ) ) * 100 = 4.11 %
v) for 80 ng mL
( ( 4.4 * 10^3 ) / ( 3.4 * 10^5 ) ) * 100 = 1.29%
vi) for 160 n mL
percentage recovery = 0%
B) what is the MBC
The value of MBC = 160 n mL because at this concentration CFU/mL = 0
c) determine if the antimicrobial tested is static or cidal
condition : If, the ratio of MBC : MIC is ≤4 then novel compound is Cidal
MBC / MIC = 160ng / 10ng = 16 : 1
hence we can conclude that the antimicrobial tested is STATIC
A 36 years old female came to see the doctor with the complaint of amenorrhea (absence of menstrual period) for past three months. She is worried if she is pregnant although she never missed her Contraceptive Pills. She recently noticed some milky discharge from her left breast and abnormal facial hairs. She also said that her period was irregular and less in amount for past one year. She also gained 15 pounds during last year but denies any cold intolerance, dry skin, depression, fatigue or hot flushes.
Her menarche was at 14 and she had regular 21 days cycle till last year when it became irregular and gradually scanty.
Her LMP (last menstrual period) was 3 months back.
She has a 10 years old healthy child (normal vaginal delivery). She has regular Pap test, last test was done 10 months ago which was normal.
Her mother had menopause at age 55.
Her vitals were normal.
Her pregnancy test was done at the office which was Negative.
The doctor reassured and discussed hormonal imbalances with her. She recommended her urine and blood tests for hormone levels and pelvic ultrasound to check her reproductive organs. The doctor advised her to come back with all the test result
1. After reading given case, what will be the most likely diagnosis of this patient?
2. Normal woman does not show and breast discharge, what could be the reason in this patient for breast discharge?
Help me answer to your best of ability
Answer:
The correct answer is -
1. galactorrhea or prolactinoma
2. hormonal imbalance (prolactin imbalance)
Explanation:
The given symptoms experienced by the patient are the absence of menstrual cycles, an increase in weight, some milky discharge from her left breast, and abnormal facial hairs. The pregnancy tests show she is not pregnant and she also does not experience cold intolerance, dry skin, depression, fatigue or hot flushes.
All these suggest that there is a hormonal imbalance in her and due to producing a white substance from the breast it can get that there is too much production of prolactin, which suppresses the effect of estrogen, which is producing by the pituitary gland.
Galactorrhea or prolactinoma are two disorders that affect the production of prolactin that cause milky discharge, it can be caused by overuse of contraceptives or underlying conditions.

Sperm cells are not normally exposed to blood, but if they are, the immune system may produce ____________ against sperm cells' ____________ and render someone sterile.
Answer:
Sperm cells are not normally exposed to blood, but if they are, the immune system may produce __auto-antibodies__ against sperm cells' __auto-antigens_ and render someone sterile.
Explanation:
Auto-antibodies are antibodies that can destroy cells from the same organism. They are mistakenly directed against organs or tissues of the same organisms, causing auto-immune diseases or affections. The autoantibodies action occurs when the organism fails in recognizing its own cells and faces them as strange elements.
Auto-antigen is the molecule produces by the body that fails in being recognized due to a break up in the tolerance mechanisms, triggering an immune response.
In the exposed example, sperm cells do not usually mix with blood. So when they do, blood cells recognize them as strange bodies and act against them. Sterility might be an effect of this auto-immune response.

At which location is contact metamorphism least likely to occur
1. divergent boundary
2. convergent boundary
3 .transform boundary
Contact metamorphism is the result of rising of hot magma, where by contact, other previously solidified rocks also metamorphize. This events occurs in convergent and divergent plate boundaries.
-------------------------------------
Contact metamorphism refers to a localized metamorphism. It occurs in the vicinity of intrusive igneous rocks and results from the term effects of hot magma.
Contact metamorphism occurs under elevated temperatures and low-pressure conditions. It is closely related to magmatism.
It occurs in oceanic dorsals, where the extremely hot magma rising to the surface metamorphizes other previously solidified magmatic rocks.
It is very common to find this metamorphism at both convergent and divergent plate boundaries, where molten rock is produced.
I. Convergent. Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one. In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices. The thicker and older plate subduces under the other plate. Also, collisions create volcanic arches and continental arches. In these boundaries, blueschists form by contact and regional metamorphisms.
II. Divergent: New crust is created by the rising molten materials coming from the mantle when two plates separate. A stream of hot material creates a new seabed between the separating plates, producing the sea bottom expansion. This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. Chlorite and plagioclase metamorphic rocks are formed by contact metamorphism.

which is an example of incomplete dominance?
a] A red flower and a yellow flower mating to produce a yellow flower.
b] A red flower and a yellow flower mating to produce a red flower.
c] A red flower and a yellow flower mating to produce an orange flower.
d] A orange flowers mating to produce an orange flower.
Answer:
c] A red flower and a yellow flower mating to produce an orange flower.
Explanation:
An incomplete dominance in biological terms means a situation where one allele doesn't totally take the expression in a gene, but rather the two parental traits combine to form a secondary trait. As a result of this, a third phenotype comes up, with the physical trait being a mix of the phenotype of the parents.
Therefore, an example of incomplete dominance is a red flower and a yellow flower mating to produce an orange flower.
Answer:D
Explanation:
D is a Orange with orange meaning its incomplete dominance because it both the same theres no other color dominance the other
During transcription, RNA polymerase synthesizes RNA from a DNA template with the help of accessory proteins.
a. True
b. False
Answer:
The correct answer is a. True
Explanation:
The information to produce a protein is coded in the cells in deoxyribonucleic acid (DNA). Transcription is the process in which a DNA sequence is copied into a ribonucleic acid (RNA) sequence. This RNA sequence is a messenger RNA (mRNA) because it will be then translated into a functional protein. For this, the DNA sequence is read and an RNA strand is synthesized by an RNA polymerase (an enzyme that synthesizes RNA molecules from a DNA template). During the process participate other proteins, such as DNA binding proteins, activators, coactivators, etc. (accessory proteins).

La actividad de agua (aw) es la cantidad de agua libre en el alimento, es decir, el agua disponible para el crecimiento de microorganismos y para que se puedan llevar a cabo diferentes reacciones químicas. Tiene un valor máximo de 1 y un valor mínimo de 0. Cuanto menor sea este valor, mejor se conservará el producto. La actividad de agua está relacionada con la textura de los alimentos: a una mayor actividad, la textura es mucho más jugosa y tierna; sin embargo, el producto se altera de forma más fácil y se debe tener más cuidado.A medida que la actividad de agua disminuye, la textura se endurece y el producto se seca más rápido. Por el contrario, los alimentos cuya actividad de agua es baja por naturaleza son más crujientes y se rompen con facilidad. En este caso, si la actividad de agua aumenta, se reblandecen y dan lugar a productos poco atractivos. En ambos casos, el parámetro de la actividad de agua del alimento es un factor determinante para la seguridad del mismo y permite determinar su capacidad de conservación junto con la capacidad de propagación de los microorganismos.Agua y microorganismosControlar la actividad de agua en alimentos es sinónimo de alargar su vida útilCuanto menor es la actividad de agua de un alimento, mayor es su vida útil. Es importante diferenciar entre cantidad de agua y actividad de agua. El primer término hace referencia a la cantidad total de agua presente en el alimento, aunque puede ser que no esté libre para interaccionar.

During alcoholic fermentation, when is NAD+ converted to NADH -- during the conversion of glucose to pyruvate (glycolysis) or during the conversion of pyruvate to alcohol?
Answer:
During the conversion of glucose to pyruvate glycolysis or during the conversion of pyruvate to alcohol
Explanation:
During the conversion of glucose to pyruvate, NAD+ is converted into NADH.
What is alcoholic fermentation?Alcoholic fermentation is a biological process that converts sugars into cellular energy while emitting ethanol and carbon dioxide as byproducts.
The NADH + H+ from glycolysis would be recycled back to NAD+ during the fermentation process, allowing glycolysis to continue. NAD+ is reduced during glycolysis to form NADH + H+.
Thus, during this, when glucose is converted to pyruvate, NAD+ is being converted to NADH.
