Gap Junctions01:37

Gap Junctions

57.2K
Multicellular organisms employ a variety of ways for cells to communicate with each other. Gap junctions are specialized proteins that form pores between neighboring cells in animals, connecting the cytoplasm between the two, and allowing for the exchange of molecules and ions. They are found in a wide range of invertebrate and vertebrate species, mediate numerous functions including cell differentiation and development, and are associated with numerous human diseases, including cardiac and...

Gap Junctions

9.6K
The cytoplasm of adjacent animal cells can exchange small molecules, ions, and secondary messengers via the communication channels which form the gap junctions. These junctions comprise a few hundred to thousands of molecular channels, each made of two halves, called the connexon hemichannel. A connexon is a hexamer of six transmembrane connexin proteins, which assemble radially, thus forming a pore or channel in the center. One connexon hemichannel docks with a corresponding connexon on the...

Normal Distribution01:11

Normal Distribution

17.3K
The normal, a continuous distribution, is the most important of all the distributions. Its graph is a bell-shaped symmetrical curve, which is observed in almost all disciplines. Some of these include psychology, business, economics, the sciences, nursing, and, of course, mathematics. Some instructors may use the normal distribution to help determine students’ grades. Most IQ scores are normally distributed. Often real-estate prices fit a normal distribution. The normal distribution is...

Normal Stress01:19

Normal Stress

1.4K
Normal stress is a type of stress that occurs when forces act perpendicular, or normal, to a material's cross-sectional area. This stress often arises in structures when subjected to axial loading, which is the application of force along the axis of an object. A practical example of this can be found in bridge truss members.
When a rod is under axial loading, the internal forces and corresponding stress are normal to the plane of the section, so it is termed normal stress. It's important to...

Close Relationships and Culture01:29

Close Relationships and Culture

243
Culture shapes how people approach attraction, choose partners, and build long-term relationships. While some preferences in mate selection appear consistent across cultures, such as men valuing physical attractiveness and women emphasizing financial resources, cultural contexts influence how these preferences are expressed and prioritized. Marriage extends beyond romantic ideals in many societies and is deeply embedded in social, economic, and religious frameworks.The Role of Culture in Mate...

Applications of Normal Distribution01:22

Applications of Normal Distribution

9.5K
The normal distribution is a useful statistical tool. One of its practical applications is determining the door height after considering the normal distribution of heights of persons, such that many can pass through it easily without striking their heads. The normal distribution can also determine the probability of a person having a height less than a specific height.
The heights of 15 to 18-year-old males from Chile from 1984 to 1985 followed a normal distribution. The mean height is 172.36...

Area of Science:

  • Human lactation physiology
  • Maternal-fetal medicine
  • Infant nutrition

Background:

  • Human lactation lacks well-defined normality parameters, unlike other major organs, creating a care gap.
  • Biological normality is characterized by natural, well-integrated function.
  • Current assessment relies on subjective measures, hindering objective evaluation.

Purpose of the Study:

  • To propose a definition and framework for biological normality in human lactation.
  • To establish objective parameters for assessing lactation initiation and established function.
  • To address the gap in the continuum of care for lactating individuals.

Main Methods:

  • Collating published data to identify preliminary lactation markers.
  • Calculating reference limits for maternal markers of secretory activation (progesterone, milk components).
  • Outlining objective measurements for established lactation (pumping, milk production, milk fat changes).

Main Results:

  • Defined biological normality using four key elements: comfort, milk supply, infant health, and maternal health.
  • Calculated reference limits for maternal blood progesterone and milk components (protein, lactose, sodium, citrate).
  • Outlined objective measures including 3-hourly pumping, 24-hour milk production, and pre- to post-feed milk fat changes.

Conclusions:

  • The proposed definition and objective measures provide a preliminary framework for assessing human lactation.
  • This framework aims to improve the objective assessment of lactation, supporting clinical care.
  • Further research can refine these objective markers for comprehensive lactation evaluation.
