What is Natural Selection?01:32

What is Natural Selection?

126.0K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

Nature and Nurture01:10

Nature and Nurture

22.2K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Chirality in Nature02:30

Chirality in Nature

16.9K
Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a snail shell pattern in a macroscopic world to an amino acid, the minutest building block of life. Most of the snails around the world have right-coiled shells because of the intrinsic chirality in their genes. All the amino acids present in the human body exist in an enantiomerically pure state, except for glycine - the sole achiral amino acid.

Multiple Regression01:25

Multiple Regression

3.8K
Multiple regression assesses a linear relationship between one response or dependent variable and two or more independent variables. It has many practical applications.
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

The Wave Nature of Light02:12

The Wave Nature of Light

60.9K
The nature of light has been a subject of inquiry since antiquity. In the seventeenth century, Isaac Newton performed experiments with lenses and prisms and was able to demonstrate that white light consists of the individual colors of the rainbow combined together. Newton explained his optics findings in terms of a "corpuscular" view of light, in which light was composed of streams of extremely tiny particles traveling at high speeds according to Newton's laws of motion.

Area of Science:

  • Oncology
  • Pharmacology
  • Natural Products Chemistry

Background:

  • Multiple myeloma (MM) remains an incurable hematologic malignancy despite advances in treatment, including autologous stem cell transplantation (ASCT) and novel targeted agents.
  • Current therapies, while improving survival, often lead to relapse and drug resistance, necessitating the exploration of new therapeutic strategies.
  • Natural products, particularly plant-derived polyphenols, are recognized for their anti-tumor properties and low toxicity, presenting a promising avenue for drug discovery.

Purpose of the Study:

  • To investigate natural polyphenols as novel therapeutic agents against multiple myeloma.
  • To explore the potential of plant extracts and their constituents in overcoming drug resistance in MM.
  • To identify new targets for improving patient outcomes in hematologic malignancies.

Main Methods:

  • Review of existing literature on natural products, specifically polyphenols, in cancer therapy.
  • Analysis of the biological activities of plant extracts, focusing on polyphenols, flavonoids, and terpenoids.
  • Evaluation of the potential of combining plant extracts with conventional anti-cancer drugs for synergistic effects.

Main Results:

  • Polyphenols, flavonoids, and terpenoids from plant extracts exhibit significant anticancer and pro-apoptosis properties.
  • Plant extracts demonstrate low toxicity towards normal cells and favorable pharmacokinetic profiles.
  • Combining plant extracts with anti-cancer drugs can enhance therapeutic efficacy by sensitizing malignant cells and overcoming resistance.

Conclusions:

  • Natural polyphenols represent a valuable resource for developing novel anti-MM agents.
  • Plant-derived compounds hold promise for improving treatment outcomes in patients with refractory or relapsed multiple myeloma.
  • Further research into natural products could lead to more effective combination therapies for hematologic malignancies.
