frozen elephant trunk for aortic arch reconstruction is associated with reduced mortality as compared to conventional techniques
wariber [46]

To compare the perioperative results of frozen elephant trunk (FET) vs. traditional elephant trunk (ET) procedures for aortic arch repair. 390 individuals had aortic repair with elephant trunk reconstruction between 2002 and 2018 at 9 facilities: Aortic dissection affected 37% of patients who received a FET (mean age: 65+/-13 years, 30% female), while 43% of patients who received an ET (mean age: 63+/-13 years, 37% female) experienced aortic dissection. In-hospital mortality, stroke, and spinal cord injury were among the outcomes of interest (SCI).

<h3>What is Aortic arch ?</h3>

The top portion of the principal artery sending blood away from the heart is known as the aortic arch. A combination of symptoms and signs known as aortic arch syndrome are linked to anatomical issues in the arteries that branch off the aortic arch. The valves, chambers, and accompanying vessels that make up the heart's interior.

<h3>What is conventional techniques ?</h3>

Conventional methods assess the long-term heat stability of polymer products at temperatures below their melting points, for instance, through accelerated aging in "circulating air ovens" until degradation effects like discolouration and embrittlement become apparent.

Answer:

 12     :    3      :    1

white : yellow : green

Explanation:

Given that genes A and B control the fruit colour in following ways:

A_B_ or A_bb = white

aaB_ = yellow

aabb =  green

The genes undergo independent assortment so:

AaBb X AaBb =

A_B_ : A_bb : aaB_ : aabb

  9     :    3     :   3      :   1

white : white : yellow: green

        12          :    3     :   1

Hence, ratio of white : yellow : green is 12: 3: 1

Which listed transfusion reaction is most often associated with transfused patient's lacking iga?
IgorC [24]
The most common transfusion reaction, especially in patients lacking either IgA especially serum IgA, is the development of potentially severe hypersensitivity reactions or anaphylaxis. The most probable culprit is the presence of IgA in the transfused blood, because since the individual lacks IgA, then the IgA in the transfused blood is considered a foreign body triggering an allergic response.
