Gene Conversion02:08

Gene Conversion

10.6K
Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

Conversion of Units

34.6K
Sometimes, there is a need to convert from one unit to another one. For instance, reading a cookbook in which quantities are expressed in units of liters or ounces may require conversion of quantities to cups. Or, when looking up directions on how to get to a location, we may be interested to know how many miles we are going to walk. In this case, we would have to convert units of feet or meters to miles.
The first step in the unit conversion is to list the given units and the units required...

Conversion of Alcohols to Alkyl Halides

8.3K
This lesson delves into the conversion of alcohols to corresponding alkyl halides and the mechanism of action for different reagents. Typically, the hydroxyl group is first protonated to convert it to a stable leaving group. Consequently, based on the starting alcohol, the mechanism undergoes either of the nucleophilic substitution routes, SN1 or SN2. Tertiary alkyl halides are made using the two-step SN1 mechanism that occurs via a carbocation intermediate, which is stabilized by...

Dimensional Analysis03:40

Dimensional Analysis

59.8K
Dimensional analysis, also known as the factor label method, is a versatile approach for mathematical operations. The main principle behind this approach is: the units of quantities must be subjected to the same mathematical operations as their associated numbers. This method can be applied to computations ranging from simple unit conversions to more complex and multi-step calculations involving several different quantities and their units.

Types of Radioactivity03:23

Types of Radioactivity

19.4K
The most common types of radioactivity are α decay, β decay, γ decay, neutron emission, and electron capture.
Alpha (α) decay is the emission of an α particle from the nucleus. For example, polonium-210 undergoes α decay:

Summary
This summary is machine-generated.

Fontan conversion surgery can improve survival and quality of life for patients with atriopulmonary Fontan. This procedure converts the atriopulmonary Fontan to an extracardiac Fontan, enhancing hemodynamics and managing atrial arrhythmias.

Area of Science:

  • Cardiology
  • Pediatric Cardiac Surgery
  • Congenital Heart Disease

Background:

  • Patients with a univentricular heart and atriopulmonary Fontan are susceptible to atrial dilation, arrhythmias, and circulatory decline.
  • The atriopulmonary Fontan is associated with long-term complications, impacting patient survival and quality of life.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of Fontan conversion surgery in patients with atriopulmonary Fontan.
  • To assess the impact of converting atriopulmonary Fontan to extracardiac Fontan on hemodynamics and atrial arrhythmias.

Main Methods:

  • A retrospective review of 149 Fontan conversion surgeries performed between 1994 and 2018.
  • Procedures included arrhythmia surgery and epicardial pacemaker placement to convert atriopulmonary to extracardiac Fontan.

Main Results:

  • Operative mortality was 2% during the study period.
  • Ten-year freedom from death or heart transplant was 84% for patients undergoing Fontan conversion.
  • The procedure demonstrated improvements in hemodynamics and control of atrial arrhythmias.

Conclusions:

  • Fontan conversion surgery is a viable option for selected patients with atriopulmonary Fontan, improving survival and quality of life.
  • Given the risks associated with atriopulmonary Fontan, all such patients should be considered for Fontan conversion evaluation.
