  • Spontaneous abortion (miscarriage) is the termination of pregnancy before completion of the 20th gestational week. The term applies to both live and stillborn fetuses weighing 500 g. However, a fetus need not be identified if other products of conception are present (e.g., placenta or membranes). Familiarity with the local legal definition is mandatory because there is considerable state to state variation. Loss of pregnancy is very common. Recent estimates are that only 62.5% of pregnancies result in live births, 21.9% end in legal abortions, 13.8% have spontaneous abortions, 1.

  • Information on long-term health consequences of unsafe abortion is scarce. The WHO estimates that about 20–30% of unsafe abortions result in reproductive tract infections and that about 20–40% of these result in upper-genital-tract infection and infertility. An estimated 2% of women of reproductive age are infertile as a result of unsafe abortion, and 5% have chronic infections. 6 Unsafe abortion could also increase the long-term risk of ectopic pregnancy, premature delivery, and spontaneous abortion in subsequent pregnancies.

  • In recent years a number of OECD countries experienced a rapid increase in housing market activity, which coincided with a period of low real and nominal interest rates. The link between the two is intuitive: low interest rates make credit cheaper and increase the demand for housing. Some scholars argue that expansionary monetary policy has been signicantly responsible for this low level of interest rates and the subsequent house price boom (Hume and Sentance (2009) and Taylor (2009)).

  • Undernutrition affects large populations of boys and girls in developing countries. Its major determinant is poverty, which usually combines with other important factors like poor breastfeeding practices and inadequate complementary foods for babies, as well as lack of basic health care, safe water and sanitation. Globally, about 150 million children under five years are undernourished, which comprises 27% of the world’s population in this age group. Twelve million of these children die every year, and protein-energy malnutrition is implicated in more than 55% of all these deaths.

  • Copyright laws are increasingly passed without democratic debate or scrutiny. In Great Britain, where I live, Parliament recently passed the Digital Economy Act, a complex copy- right law that allows corporate giants to disconnect whole families from the Internet if any- one in the house is accused (without proof) of copyright infringement; it also creates a “Great Firewall of Britain” that is used to censor any site that record companies and movie studios don't like.

  • The lung has a unique vascular structure and function; it has low pressure, low resistance circulation with a highly compliant system which accommodates the same amount of flow as the systemic circulation. In addition, pulmonary and systemic vasculatures have divergent responses to various stimuli. For example, pulmonary arteries constrict in the setting of hypoxia, while systemic circulation dilates. This is due to distinctive developmental characteristics, anatomic and histological structure, as well as physiological properties.

  • Workman’s background as a trailer-maker convinced him that “you could capture the essence of a memorable film in as little as a single shot—if you chose the shot carefully enough.” (Birchard, 91) His assemblage of these “essences” places images together for broad generic or thematic reasons, as well as on the basis of simple physical resemblance (similar shots of darting eyes, people popping bubble-gum) or gag value (one clip finishing a sentence from another).

  • Maternal Age and Trisomy The association between increasing maternal age and trisomy is the most important etiologic factor in congenital chromosomal disorders. Among women under the age of 25, ~2% of all clinically recognized pregnancies are trisomic; by the age of 36, however, this figure increases to 10% and by the age of 42, to 33% (Fig. 63-5). This association between maternal age and trisomy is exerted without respect to race, geography, or socioeconomic factors and likely affects segregation of all chromosomes.

  • Vitrification has been investigated for tissue-engineered bone and blood vessels. Liu & McGrath (2003) explored the potential of vitrification for the cryopreservation of tissueengineered bone constructs consisting of a hydroxyapatite scaffold-cell complex. Cell survival was 92.0% for suspended cells and 43.0% for attached cells. In terms of tissueengineered blood vessel constructs, the effects of vitrification and conventional cryopreservation were compared (Elder et al., 2005). Collagen-based vascular constructs were used as models in this study.
