...Megan and Dennis Doyle of Minneapolis decided they wanted to do more than just volunteer or write a check. Instead, they took $30,000 of their own money and started a nonprofit called Hope for the City. The organization collects corporate overstock and distributes it to nonprofits in the Twin Cities, nationwide, and internationally to 26 developing countries. Today the nonprofit has a $900,000 operating budget and a 25,000-sq.-ft. warehouse to store the donated items and has distributed nearly $380 million of in-kind merchandise since its inception. "This makes us feel like...
...think that the egg probably carried an X and one sperm an X, and one sperm a Y. It's possible that it is far more complicated than that. But that's the simplified explanation," says Souter. The twins have different proportions of male cells (XY) and female cells (XX), and are chimeric, meaning they have tissue with a diverse genetic make-up. Twin A, identified as a hermaphrodite, has 5% XY and 95% XX after genetic testing of the skin. Comparatively, Twin B, the male...
...urology and human genetics at the David Geffen School of Medicine at UCLA says: "You don't need to have 100% Y-chromosome to be male. If you have more than 15% of Y-chromosome in the gonads it's likely that you're going to be a male." Twin A, he adds, is ambiguous because the number of cells carrying a male-determining chromosome was not high enough to masculinize the twin. "They're both ambiguous, if you will, but only one is from a genital perspective." Vilain adds that people should retire the term hermaphrodite should use "intersex...
...Souter says that biologist Michael Golubovsky has been postulating on this type of twin for some time, calling them sesquizygotic, and has laid out some potential mechanisms. "It's fascinating that he has described these twins and also had suggested that it may be associated with a disorder of sex development...
Saddam's fall brought joy to most Iraqis, but Yasser had additional reasons to celebrate. A few days after the regime's fall, Sheherezad gave birth to twin girls: Tabarek and Aya. There were complications. The babies were premature, and Tabarek was weak. Much of the pediatric hospital's life-support equipment was lost to the looting mobs that rampaged through Baghdad after the collapse of the old regime, so doctors had to rely on one old, malfunctioning incubator. Tabarek later developed learning difficulties that, her doctors believe, resulted in part from poor postnatal attention...
