When an egg cell is fertilised by a sperm, it begins to divide into a cluster of cells known as a blastocyst, the early stage of the embryo. Within this ball of cells, some cells form the inner cell mass – which will develop into the foetus – and some form the outer wall, which becomes the placenta…

Bunions are likely inherited and not caused by faulty footwear, Counsel and Heal reported. Bunions are a painful foot condition characterized by bony bumps that form on the joint at the base of the big toe.  Earlier research indicates that 23 percent of people 18 to 65 years of age and 36 percent of people over the age of 65 have bunions. The new study, published in the journal Arthritis Care and Research, analyzed information from 1,370 people, with an average age of 66 years old, who were enrolled in the Framingham Foot Study. Each participant received a foot exam between 2002 and 2008 to screen for bunions, toe deformities or plantar soft tissue atrophy, a breakdown of the fatty “cushion” under the ball of the foot, Counsel and Heal reported. The study found that 31 percent of participants had bunions and 30 percent had toe deformities like “hammer toes,” both of which were highly inheritable, depending on age and sex, especially among people of European descent. Twenty-eight percent had plantar soft tissue atrophy, but this condition was not found to inheritable.                 “Our study is the largest investigation of the heritability of common foot disorders in older adults, confirming that bunions and lesser toe deformities are highly inheritable in Caucasian men and women of European descent,” Dr. Marian Hannan from Hebrew SeniorLife and Harvard Medical School in Boston said in a news release. “These new findings highlight the importance of furthering our understanding of what causes greater susceptibility to these foot conditions, as knowing more about the pathway may ultimately lead to early prevention or early treatment,” she concluded.

New Jersey mom Lisa McGreevey spent Sunday in the hospital, but it was still her best Mother’s Day ever. That’s because she was at the bedside of her 8-year-old son, who nearly died after being struck in the chest by a baseball the day before but was recovering nicely. “This is the best Mother’s Day gift ever,” said McGreevey, of Northvale, N.J., as she watched over Ian at Hackensack University Medical Center. “We’re so thankful he’s OK,” the beaming mom said. “The woman who saved Ian was an angel. I want to thank her so much.” Good Samaritan Maureen Renaghan, a mom from the other team, had told The Post after her amazing save that she was just “glad I could do anything to help that family and that child.” As Ian collapsed Saturday, Renaghan, 40, sprinted from the stands over to him. She has told how he had stopped breathing and lost his pulse, with his eyes rolling back in his head. She kneeled over the boy and started compressing his chest and blowing into his mouth until he was breathing on his own. Renaghan, of Harrington Park, learned CPR 20 years ago for a camp-counselor job. Her husband coaches their 10-year-old son Jack’s team — which is called the Angels. Ian was rushed to Hackensack University Medical Center’s Westwood campus. Doctors there sent him by airlift to the hospital’s main Hackensack facility for further treatment. The day after his brush with death at Highland Field in Harrington Park, Ian was watching cartoons and eating pancakes in his hospital bed, recalling his frightening ordeal. “I was on second base, and the catcher dropped the ball,” Ian said. “So I decided to steal third. As I slid in, the ball hit my chest and lungs. Right away, I felt dizzy. It was scary.” Meanwhile, Ian accepted an invitation to Citi Field to watch his favorite team — and player, David Wright — in action sometime soon.
