Ribosome Profiling02:24

Ribosome Profiling

4.2K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

Drug Dosing: Infants and Children01:29

Drug Dosing: Infants and Children

295
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Background and Environment Affect Phenotype02:27

Background and Environment Affect Phenotype

7.7K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Taping Over Different Ground Profiles01:12

Taping Over Different Ground Profiles

378
Taping over varying ground profiles requires careful adaptation to achieve accurate measurements. On smooth, level ground with minimal vegetation, the tape can rest directly on the ground. Here, the taping team, typically consisting of a head and a rear tapeman, coordinates their positions with clear communication. The rear tapeman holds the tape at the starting point and guides the head tapeman toward a range pole placed beyond the endpoint, using hand or voice signals to ensure alignment.On...

Profile Leveling and Cross Sections01:26

Profile Leveling and Cross Sections

1.6K
Profile leveling and cross-sections are surveying methods used to determine and document terrain elevations for infrastructure projects such as highways, railroads, canals, and pipelines. These methods provide data for earthwork planning and alignment of proposed routes.  Profile leveling involves measuring elevations along a fixed line to create a vertical terrain profile. A surveyor sets up a leveling instrument at the benchmark (BM) and records a backsight (BS) to determine the...

Drug Dissolution: Requirements and Profile Comparison

272
The acceptance criteria for dissolution profile data are anchored in Q values, representing the percentage of drug dissolved within a specified period. This assessment unfolds in three stages:First Stage: The test passes if all six drug dosage units are equal to or greater than Q plus 5%; otherwise, the sample proceeds to the second stage.Second Stage: The average of twelve units must be equal to or greater than Q, with no unit falling below Q - 15% to pass; if not, it progresses to the final...

Summary

Children with recurrent acute otitis media (RAOM) and otitis media with effusion (OME) show distinct clinical patterns. Allergy and atopy are significantly more prevalent in RAOM with OME cases, suggesting a complex clinical presentation.

Area of Science:

  • Pediatric Otolaryngology
  • Allergy and Immunology
  • Epidemiology

Background:

  • Otitis-prone children exhibit distinct clinical patterns.
  • Known risk factors for recurrent acute otitis media (RAOM) exist, but epidemiological models explaining clinical heterogeneity are lacking.
  • The role of allergic disease in different otitis-prone phenotypes requires investigation.

Purpose of the Study:

  • To evaluate the potential impact of allergic disease on distinct clinical phenotypes in otitis-prone children (aged 3-10 years).
  • To differentiate between simple RAOM and RAOM with otitis media with effusion (OME) between acute infections.

Main Methods:

  • A retrospective pilot study analyzed data from 153 otitis-prone children (aged 3-10 years).
  • Children were categorized into simple RAOM or RAOM with OME groups.
  • Prevalence of atopy, allergy, adenoidal hypertrophy, chronic adenoiditis, conductive hearing loss, and tympanometry results were compared between groups.

Main Results:

  • 75.8% of children had simple RAOM, while 24.2% had RAOM with OME.
  • Atopy and allergy were significantly more prevalent in children with RAOM with OME (atopy: 73.0% vs. 39.5%; allergy: 60.0% vs. 36.1%).
  • RAOM with OME was associated with higher rates of adenoidal hypertrophy, chronic adenoiditis, conductive hearing loss, and impaired tympanometry.

Conclusions:

  • Children with RAOM with OME present a more complex clinical picture than those with simple RAOM.
  • This complexity includes adenoidal disease, audiological impairment, and a higher incidence of underlying allergy or atopy.
  • Further epidemiological studies are needed to investigate the role of these factors in the heterogeneous manifestations of otitis-prone conditions.
