What is Conservation Biology?

24.0K
Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

Conservation of Small Populations02:04

Conservation of Small Populations

16.7K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Papillary Dermis

5.5K
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Conserved Binding Sites01:49

Conserved Binding Sites

5.1K
Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally...

Conservation of Protein Domains Over Different Proteins02:26

Conservation of Protein Domains Over Different Proteins

14.1K
Protein domains are small structurally independent units that are part of a single amino acid chain.  Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

The Thyroid Gland01:23

The Thyroid Gland

6.9K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Area of Science:

  • Endocrinology
  • Surgical Oncology
  • Thyroid Cancer Research

Background:

  • American Thyroid Association (ATA) guidelines recommend thyroid lobectomy for papillary thyroid microcarcinomas (PTMC) < 1 cm.
  • Thyroid lobectomy carries risks, including vocal cord palsy.
  • Conservative thyroidectomy, a less invasive approach, involves partial removal of the cancerous lesion.

Purpose of the Study:

  • To evaluate the oncologic safety and functional outcomes of conservative thyroidectomy for PTMC.
  • To assess the applicability of conservative thyroidectomy as an alternative to thyroid lobectomy.

Main Methods:

  • Retrospective analysis of 79 PTMC patients who underwent conservative thyroidectomy.
  • Evaluation of oncologic results, including recurrence rates.
  • Assessment of postoperative complication incidence and recovery.

Main Results:

  • A low recurrence rate of 5.0% (2 local, 2 regional) was observed.
  • All recurrences were successfully managed with further surgery.
  • Temporary complications like vocal cord palsy and hypocalcemia occurred in 1 patient each, with full recovery.

Conclusions:

  • Conservative thyroidectomy is an oncologically sound and functionally safe procedure for PTMC.
  • This approach can be considered a safe alternative to thyroid lobectomy for PTMC surgical management.
