The majority of studies indicate antibiotics do interfere with contraceptive pills, such as clinical studies that suggest the failure rate of contraceptive pills caused by antibiotics is very low (about 1%). In cases where antibacterials have been suggested to affect the efficiency of birth control pills, such as for the broad-spectrum antibacterial rifampicin, these cases may be due to an increase in the activities of hepatic liver enzymes' causing increased breakdown of the pill's active ingredients. Effects on the intestinal flora, which might result in reduced absorption of estrogens in the colon, have also been suggested, but such suggestions have been inconclusive and controversial. Clinicians have recommended that extra contraceptive measures be applied during therapies using antibacterials that are suspected to interact with oral contraceptives.
What do physicians recommend to counteract this potential issue?
****
The answer: extra contraceptive measures

From late 2009 a handful of mainly southern eurozone member states started being unable to repay their national Euro-denominated government debt or to finance the bail-out of troubled financial sectors under their national supervision without the assistance of third parties. This so-called European debt crisis began after Greece's new elected government stopped masking its true indebtedness and budget deficit and openly communicated the imminent danger of a Greek sovereign default. Seeing a sovereign default in the eurozone as a shock, the general public, international and European institutions, and the financial community started to intensively reassess the economic situation and creditworthiness of eurozone states. Those eurozone states being assessed as not financially sustainable enough on their current path, faced waves of credit rating downgrades and rising borrowing costs including increasing interest rate spreads. As a consequence, the ability of these states to borrow new money to further finance their budget deficits or to refinance existing unsustainable debt levels was strongly reduced.
What did the eurozone states that were thought to not be able to repay their debt face as a consequence?
****
The answer: the ability of these states to borrow new money to further finance their budget deficits or to refinance existing unsustainable debt levels was strongly reduced

Compounds that contain a carbon-copper bond are known as organocopper compounds. They are very reactive towards oxygen to form copper(I) oxide and have many uses in chemistry. They are synthesized by treating copper(I) compounds with Grignard reagents, terminal alkynes or organolithium reagents; in particular, the last reaction described produces a Gilman reagent. These can undergo substitution with alkyl halides to form coupling products; as such, they are important in the field of organic synthesis. Copper(I) acetylide is highly shock-sensitive but is an intermediate in reactions such as the Cadiot-Chodkiewicz coupling and the Sonogashira coupling. Conjugate addition to enones and carbocupration of alkynes can also be achieved with organocopper compounds. Copper(I) forms a variety of weak complexes with alkenes and carbon monoxide, especially in the presence of amine ligands.
Which form of copper is shock sensitive?
****
The answer: Copper(I) acetylide

In late December, Barcelona's appeal to the Court of Arbitration for Sport was unsuccessful and the original transfer ban was reinstated, leaving the club unable to utilise the 2015 winter and summer transfer windows. On 5 January 2015, Zubizareta was sacked by the board after 4 years as director of football. The next month, Barcelona announced the formation of a new Football Area Technical Commission, made up of vice-president Jordi Mestre, board member Javier Bordas, Carles Rexach and Ariedo Braida.
After firing the director, what did Barcelona form?
****
The answer:
Football Area Technical Commission
