Bala Cynwyd, PA (PRWEB) August 25, 2014 Shady Grove Fertility is pleased to announce the expansion of our Bala Cynwyd office to five days a week, beginning September 8, 2014. At the Bala Cynwyd office, patients will have the opportunity to see Dr. Isaac E. Sasson and Dr. Sunita Kulshrestha, who are board certified in reproductive endocrinology and infertility and have extensive experience treating fertility patients. Each day we have the great privilege of helping couples throughout Pennsylvania grow their families," said Dr. Sasson. "As Shady Grove Fertility has continued to expand in the Philadelphia area, we saw the need to open our Bala Cynwyd office full time to better serve patients from the Wynnewood and Main Line areas." Shady Grove Fertility as a center of excellence provides individualized care, high success rates, and revolutionary financial options, such as the 100 percent refund program for in vitro fertilization (IVF) or donor egg treatment. Two years ago, SGF opened its first Pennsylvania office in order to provide enhanced care and convenience for local patients. Since that time, three full service offices have opened in Chesterbrook, Harrisburg, and Reading. The new Bala Cynwyd office represents our first expansion into the Main Line … Continue reading →

FAITH THE 5-MINUTE PRO-LIFER Making the Case for Life Like It Has Never Been Heard Before by: FR. GAMMY TULABING How to Defend Your Pro-Life Views in 5 Minutes or Less I would like to share with you this article from Scott Klusendorf. Suppose that you have just five minutes to graciously defend your pro-life beliefs with friends or classmates. Can you do it with rational arguments? What shouldyou say? And how can you simplify the abortion issue for those who think it is hopelessly complex?Here is how to succeed in three easy steps: 1) Clarify the issue Pro-life advocates contend that elective abortion unjustly takes the life of a defenseless human being. This simplifies the abortion controversy by focusing public attention on just one question: Is the unborn a member of the human family? If so, killing him or her to benefit others is a serious moral wrong. It treats the distinct human being, with his or her own inherent moral worth, as nothing more than a disposable instrument. Conversely, if the unborn are not human, killing them for any reason requires no more justification than having a tooth pulled. In other words, arguments based on choice or privacymissthe … Continue reading →

ASHEBORO It is that time again. I have to get my mind thinking about school and the programs that we can offer our school systems. North Carolina Cooperative Extension and 4-H are grounded in education and that positions us to be helpful collaborators with our local school systems. Together we know what it takes to help youth achieve in the school setting. We offer Health Rocks for students in middle school. We implement chick embryology in the second grade. We offer water conservation lessons in third grade; bicycle safety education in fourth grade and environmental field days in fifth grade. Keeping kids in school and on task is not always easy. For youth who feel that school content is too hard or their test scores indicate they are not passing a course, the idea of dropping out can look like an ideal solution. Unfortunately, this is all to often the case. Dropping out of school is NOT an ideal solution. Youth who have been introduced to 4-H through a community club, school enrichment or special interest program know our programs are hands on. Using a hands on approach allows youth to become involved in an activity, determine what was useful … Continue reading →

Gavin Saul is a busy guy this week. Theres an embryology exhibit to man. Hes involved in ham radio activities. And hes playing viola with Jeff Robbins in a Mountain Music, Stories and Dance show while his hen, Yolk, wanders nearby. Its just another week at the Prince William County Fair for the 13-year-old Manassas resident. The fair, which is celebrating its 65th anniversary this year, will be at the county fairgrounds in Manassas through Saturday. Billed as the largest county fair in Virginia, the event put on by the Veterans Farm Club usually draws about 85,000 visitors each year and employs more than 300 volunteers. And while some things have changed over the years for example, most of the livestock now comes from surrounding counties since farms in Prince William have dwindled theres a lot that hasnt, said Edward Roseberry, the secretary of the board of directors for the fair. Chiefly, the fair remains a family affair at heart, with people trying to keep the areas agricultural traditions alive. Roseberrys father, Kite, was one of the founders of the fair. Edward has been working with the fair since 1992 and attending since the mid-1950s, he said. Its a family … Continue reading →

Chesterbrook, PA (PRWEB) August 12, 2014 After a period of trying to conceive without success, couples are understandably frustrated and confused. Taking the first step to recognize infertility and learn about the options available is often the most difficult. At Shady Grove Fertilitys free informational seminar on Wednesday, August 13, Dr. Isaac Sasson and staff members will educate future parents about fertility treatments, financial programs, and available insurance options. Eligible attendees will receive a complimentary new patient consultation or second opinion consultation at Shady Grove Fertility offices in Bala Cynwyd, Chesterbrook, Reading, or Harrisburg. During the seminar, Dr. Sasson will review the range of fertility treatments available from low-tech options like intrauterine insemination (IUI) to more advanced treatments like in vitro fertilization (IVF) and donor egg. Shady Grove Fertility takes an individualized, stepped approach to treatment, presenting many patients with successful results before trying IVF. At this informational seminar, the staff and I will introduce prospective patients to our practice. We believe in a personalized approach with every patient, and this seminar is a great way to begin our relationship, says Dr. Sasson. Prospective patients often have many questions about the cost and affordability of infertility treatment. This seminar is … Continue reading →

Where do a zebra's stripes, a leopard's spots and our fingers come from? The key was found years ago by the man who cracked the Enigma code. In 1952 a mathematician published a set of equations that tried to explain the patterns we see in nature, from the dappled stripes adorning the back of a zebra to the whorled leaves on a plant stem, or even the complex tucking and folding that turns a ball of cells into an organism. His name was Alan Turing. More famous for cracking the wartime Enigma code and his contributions to mathematics, computer science and artificial intelligence, it may come as a surprise that Turing harboured such an interest. In fact, it was an extension of his fascination with the workings of the mind and the underlying nature of life. The secret glory of Turing's wartime success had faded by the 1950s, and he was holed up in the grimly industrial confines of the University of Manchester. In theory he was there to develop programs for one of the world's first electronic computers a motley collection of valves, wires and tubes but he found himself increasingly side-lined by greasy-fingered engineers who were more focused … Continue reading →

When embryonic cells get the signal to specialize the call can come quickly. Or it can arrive slowly. Now, new research from Rockefeller University suggests the speed at which a cell in an embryo receives that signal has an unexpected influence on that cell's fate. Until now, only concentration of the chemical signals was thought to matter in determining if the cell would become, for example, muscle, skin, brain or bone. "It turns out that if ramped up slowly enough an otherwise potent signal elicits no response from the receiving cells. Meanwhile, a pulsing, on-off signal appears to have a stronger effect than a constant one," says researcher Ali Brivanlou, Robert and Harriet Heilbrunn Professor and head of the Laboratory of Molecular Vertebrate Embryology. This research is the latest collaboration between Brivanlou and Eric Siggia, Viola Ward Brinning and Elbert Calhoun Brinning Professor at Rockefeller's Center for Studies in Physics and Biology. "Until now, it has not been feasible to test how speed or other temporal dynamics affect a cell's response to a signal. However, by adapting technology that allows for very precise control over these aspects, we found unequivocal evidence that signal level alone does not determine a cell's … Continue reading →

Ben Birchall/PA Wire Christian ethicists have joined scientists in expressing concern about the latest Government steps towards creating what have been dubbed "three-parent babies". The Church of England is among those calling for more research. The Government last week published its response to a 12-week Human Fertilisation and Embryology Authority (HFEA) consultation on draft regulations to permit the use of new techniques to prevent transmission of seriousmitochondrial disease from mother to child. Some oppose the proposed IVF technique, "mitochondrial replacement therapy", because they believe it is a form of genetic modification and creates children with, in effect, three parents. The Government response emphasises that no nuclear DNA, which provides physical and other traits that children inherit from their parents, would be contributed from the donated female egg or embryo. The Government has consistently rejected claims that the techniquesconstitute genetic modification. Critics are protesting in particular against the Government's working definition in the document of genetic modification to mean the modification only of nuclear DNA in the chromosome meaning that mitochondrial donation techniques are not being counted as actual genetic modification. It is estimated that one in 6,500 children are born each year with serious mitochondrial DNA disorder which can have … Continue reading →
