Mixtures of Acids03:27

Mixtures of Acids

21.6K
The pH of a solution containing an acid can be determined using its acid dissociation constant and its initial concentration. If a solution contains two different acids, then its pH can be determined using one of several methods depending upon the relative strength of the acids and their dissociation constants.
A Mixture of a Strong Acid and a Weak Acid
In a mixture of a strong acid and a weak acid, the strong acid dissociates completely and becomes a source of almost all the hydronium ions...

Amino acids03:42

Amino acids

104.9K
Amino acids are the monomers that comprise proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, or the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. There are 20 common amino acids present in proteins, each with a different R group. Variation in the amino acid sequence is responsible for...

Polyprotic Acids03:38

Polyprotic Acids

31.9K
Acids are classified by the number of protons per molecule that they can give up in a reaction. Acids such as HCl, HNO3, and HCN that contain one ionizable hydrogen atom in each molecule are called monoprotic acids. Their reactions with water are:

Nucleic acids

189.2K
Nucleic acids are the most important macromolecules for the continuity of life. They carry the cell's genetic blueprint and carry instructions for its functioning.
DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...

Acidity of Carboxylic Acids01:21

Acidity of Carboxylic Acids

8.7K
Carboxylic acids are the strongest organic acids. However, their acidic strength is much less than mineral acids like HCl. Carboxylic acids ionize in water and readily lose the hydroxyl proton to form a resonance-stabilized carboxylate ion.

Summary

Zoledronic acid significantly reduced fracture incidence in postmenopausal women over 65 with osteopenia. However, due to cost and other risk factors, treatment should be reserved for those with high overall fracture risk.

Area of Science:

  • Gerontology
  • Pharmacology
  • Bone Metabolism

Background:

  • Osteopenia affects half of women over 65.
  • Fractures are common in this demographic.
  • Zoledronic acid is a potential treatment.

Purpose of the Study:

  • To assess zoledronic acid's effect on fracture incidence in older women with osteopenia.
  • To evaluate the clinical implications and cost-effectiveness of this treatment.

Main Methods:

  • Randomized, double-blind, placebo-controlled trial.
  • 2000 women aged 65+.
  • 6-year treatment period with zoledronic acid.

Main Results:

  • Statistically significant reduction in fracture incidence observed.
  • Potential overestimation of treatment effect due to study selection.
  • High healthcare costs associated with widespread treatment.

Conclusions:

  • Zoledronic acid reduces fractures in osteopenic women over 65.
  • Treatment decisions must consider overall fracture risk, not just bone density.
  • Reserve zoledronic acid for osteopenic women with high fracture risk factors.
