Resistance Level

In technical analysis, a price that a security does not, or only rarely, rise above. Technical analysts identify a resistance level by looking at past performance. When the security approaches the resistance level, it is seen as an indication to sell the security, which will increase the supply, causing the security's price to fall back below the resistance level. If there are too many buyers, however, the security rises above the resistance level. When this occurs, the price of the security will likely continue to rise until it finds another resistance level. It is also called the overhead resistance level. See also: Price ceiling, Support (Support level).

Resistance, or resistance level, is the top of a stock's current trading range, and the point at which the price is higher than investors are willing to pay. As stockholders sell at resistance level, the stock price goes down because supply exceeds demand.

For example, if, on a repeated basis, as stock A's price reaches $60, stockholders begin to sell, then $60 is considered its resistance level. But a trading range isn't fixed and investor attitudes change, so the resistance level tends to move higher or lower over time.

If stock A rises to $63 without a surge of selling, the current resistance line has been breached. This may be the result of a rising market or a bullish assessment of the stock's value. On the other hand, if selling increases at $57, that may become the new resistance level.

Conversely, the level at which demand exceeds supply and investors typically buy a certain stock is called support. It's the point that's considered the bottom of a stock's current trading range.

Technical analysts use the concepts of resistance and support in anticipating future stock price movements.

The Antibiotic sensitivity tests conducted on the bacteria isolates to ascertain their level of resistance to commonly used antibiotics revealed multiple drug resistance of four to eight antibiotics among the 32 strains of bacteria belonging to the genera Escherichia, Staphylococcus, Salmonella and Streptococcus.
All 3 of these isolates demonstrated multiple drug resistance. One demonstrated intermediate susceptibility to penicillin (MIC: 0.25 [micro]g/ml) and resistance to erythromycin and clindamycin.
coli MAR system regulates more than 80 genes with varying roles in multiple drug resistance. The acrAB genes produce multiple antibiotic efflux pump proteins.
Using Rigel's proprietary functional assays that are designed to identify the peptides that change the cell's biological outcome in the desired way (i.e., those tumor cells that survive in the presence of Taxol), the researchers identified seven peptides that allowed for increased Taxol resistance, one of which consistently had the highest survival rate and was linked to upregulation of the gene ABCB1 (also known as MDR1 for multiple drug resistance).
By the end of the 1950s, many clinical studies revealed staphylococcus with multiple drug resistance. In 1960, the introduction of semisynthetic antistaphylococcal penicillins such as methicillin, increased the therapeutic choices as did the introduction of first-generation cephalosporins several years later.
