Empathy02:34

Empathy

10.1K
Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.

CRISPR01:59

CRISPR

57.8K
Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced...

Cleavage and Blastulation01:33

Cleavage and Blastulation

50.1K
After a large-single-celled zygote is produced via fertilization, the process of cleavage occurs while zygotes travel through the uterine tube. Cleavage is a mitotic cell division that does not result in growth. With each round of successive cell division, daughter cells get increasingly smaller.

Reproductive Cloning01:27

Reproductive Cloning

32.7K
Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic...

Bacterial Signaling01:30

Bacterial Signaling

40.6K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

In-vitro Mutagenesis01:16

In-vitro Mutagenesis

16.3K
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Area of Science:

  • Dental implantology
  • Prosthodontics
  • Surgical instrumentation

Background:

  • Implant angulation is critical for successful prosthetic and functional outcomes.
  • Conventional surgical stents have limitations in guiding sequential drilling for implant placement.
  • Computer-Aided Design (CAD) printed stents offer guide sleeves for sequential drilling.

Purpose of the Study:

  • To fabricate a drill bit guide for surgical stents.
  • To accurately transfer planned angulation and implant placement.
  • To ensure a prescribed drilling sequence for dental implants.

Main Methods:

  • Fabrication of a surgical stent with a threaded guide ring system.
  • Incorporation of an internal drill bit guiding system.
  • Utilizing interchangeable sequential drilling for predetermined drill bit positioning.

Main Results:

  • The fabricated surgical stent with a drill bit guiding system demonstrated high accuracy.
  • The system achieved less than 1% error in implant placement.
  • A mean deviation of 0.48% was recorded, indicating minimal error.

Conclusions:

  • The developed drill bit guide effectively limits and transfers angulation and placement.
  • The system allows for precise execution of planned implant positioning with minimal alteration.
  • This leads to predictable and successful prosthetic outcomes in dental implant procedures.
