Long-patch Base Excision Repair

7.9K
Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

Chemical Formulas

61.0K
A chemical formula presents information about the proportions of atoms constituting a particular chemical compound or molecule, mainly using symbols of elements and numbers. At times other symbols, such as dashes, parentheses, brackets, commas, plus, and minus signs, are also used. A chemical formula can be one of three types – molecular, empirical, and structural.

Chemical Equations

80.8K
Chemical equations represent the identities and relative quantities of substances involved in a chemical reaction. The substances undergoing reaction are called reactants, and their formulas are placed on the left side of the equation. The substances generated by the reaction are called products, and their formulas are placed on the right side of the equation. Plus signs (+) separate individual reactant and product formulas, and an arrow (→) separates the reactant and product (left and right)...

Chemical Reactions

A chemical reaction is a process by which the bonds in the atoms of substances are rearranged to generate new substances. Matter cannot be created or destroyed in a chemical reaction—the same type and number of atoms that make up the reactants are still present in the products. Merely, the rearrangement of chemical bonds produces new compounds.

Patch Clamp

6.4K
Many fundamental cell functions such as muscle contraction and nerve transmission rely on the electrical signals produced by the movement of positively and negatively charged ions across the cell membrane. One competent method to record current flowing across the whole cell or single ion channel is the patch-clamp technique.
In this method, a glass micropipette containing electrolyte solution is tightly sealed against a small portion of the cell membrane. As a result, a patch of the cell...

Types of Chemical Bonds

93.8K
Chemical bonding theories were pioneered by American chemist Gilbert N. Lewis. He developed a model called the Lewis model to explain the type and formation of different bonds. Chemical bonding is central to chemistry; it explains how atoms or ions bond together to form molecules. It explains why some bonds are strong and others are weak, or why one carbon bonds with two oxygens and not three; why water is H2O and not H4O.

Summary
This summary is machine-generated.

Patch testing with hairdressing chemicals effectively diagnoses allergic contact dermatitis in various occupations. A specialized hairdresser series identified more allergies than standard testing alone.

Area of Science:

  • Dermatology
  • Allergology
  • Occupational Health

Background:

  • Hairdressing chemicals are a known cause of allergic contact dermatitis.
  • Patch testing is a key diagnostic tool for identifying specific allergens.

Purpose of the Study:

  • To evaluate the utility of patch testing with hairdressing chemicals.
  • To assess the effectiveness of a supplemental "hairdresser series" in diagnosing allergies.

Main Methods:

  • Retrospective review of 210 patients patch-tested between 2000-2008.
  • Utilized a standard allergen series and a supplementary "hairdresser series" containing 18 additional chemicals.
  • Analyzed patch test results and patient occupations.

Main Results:

  • The scalp, face, and hands were the most common dermatitis sites.
  • Cosmetologists, housewives, and beauticians were common occupations among patients.
  • The supplemental hairdresser series identified 13 additional patients (6.4%) with allergies.
  • Ammonium persulfate (14.4%), 4-aminoazobenzene (13.4%), and pyrogallol (9.1%) showed the highest allergic rates in the supplemental series.

Conclusions:

  • Patch testing with both standard and supplemental hairdressing chemicals is valuable across diverse patient occupations.
  • The supplemental hairdresser series significantly enhances the detection of allergies compared to standard series alone.
