When Nichelle Obar learned she was pregnant with her second child last year, she never expected that her pregnancy, or her baby, would make history.
But when the 40-year-old food-and-beverage coordinator from Hawaii and her fiancé Christopher Constantino went to their 18-week ultrasound, they learned something was wrong. The heart was larger than it should have been, and there was evidence that fluid was starting to build up around the organ as well. Both were signs that the fetus was working extra hard to pump blood to its fast-growing body and that its heart was starting to fail.
Obar’s doctor knew what could be causing it. Obar and Constantino are both carriers of a genetic blood disorder called alpha thalassemia, which can lead to dangerously low levels of red blood cells. Red blood cells carry hemoglobin, which binds to oxygen and transports it from the lungs to feed other cells–so fewer red blood cells means low levels of oxygen in cells throughout the body. Neither parent is affected by the condition, but depending on how their genes combined, their children could be.

When Obar was pregnant with their first child, Gabriel, the couple was told that if he had the disease, his prognosis would be grim. “The information we got was that most babies don’t survive, and if they do survive to birth, they might not live for too long,” Obar says. Gabriel was lucky. The DNA he inherited from his mom and dad did not endow his cells with enough o…

This study investigated the effects of Parkia biglobosa aqueous seed extract on some biochemical, haematological and histopathological indices in streptozotocin-induced diabetic rats.Materials and MethodsWistar rats of either sex (180–300 g) were fasted overnight and diabetes mellitus induced using streptozotocin 40 mg/kg IP. Diabetes mellitus (fasting blood glucose ≥ 200 mg/dl) was confirmed 48 hours later. The rats were randomly grouped into six groups (n = 5): Group 1 (diabetic untreated control), group 2 (Parkia biglobosa 200 mg/kg), group 3 (Parkia biglobosa 400 mg/kg). group 4 (…

Conclusion: Our results indicate that Angpt-2 may play an important role in ovarian tissue transplantation after cryopreservation although further studies are needed to understand its exact function.

Conclusion: In PCOS patients undergoing IVF, early administration of a GnRH antagonist may possibly lead to benefits due to a reduced incidence of moderate-to-severe OHSS in high-risk subjects with a better clinical pregnancy rate per embryo transfer. Further studies with more subjects are required.

Conclusion: The present study demonstrated that partial ZP thinning or drilling resulted in similar outcomes in implantation and pregnancy rates using thawed embryos, irrespective of women’s age or ZP thickness.

This study was a retrospective analysis involving 191 IVF cycles in which all embryos had over 10% fragmentation (grade 3 or 4) on day 2 of the IVF-embryo transfer cycle from March 2015 to December 2017. IVF cycles were divided into the fragment removal group (n=87) and the no fragment removal group (n=104) as a control cohort. Before fragment removal, embryos with fragmentation on day 2 were incubated in Ca2+- and Mg2+-free biopsy medium under paraffin oil for 30 minutes. Microsurgical fragment removal was performed with later-assisted hatching and a handmade suction micropipette that had an outer diameter of 30 µm….

Conclusion: The data obtained from the present study suggest that higher levels of both serum fetuin-A and oxidative stress markers might be related with PCOS.

Abstract
In an age when a small quantity of sperm can lead to pregnancy through in vitro fertilization or intracytoplasmic sperm injection, selecting healthy sperm is important. Sperm DNA fragmentation (SDF) is known to be higher in infertile men. Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labeling (TUNEL) and the alkaline comet test are SDF tests that directly measure DNA damage and have shown closer correlations with assisted reproduction results than indirect tools such as the sperm chromatin structure assay or the sperm chromatic dispersion test. It is diff…

Abstract
AIM: To explore possible inter-relationships of various biomarkers of inflammation and lifestyle and other cardiovascular risk factors (age, gender, smoking history, hypertension, Type 2 diabetes, dyslipidemia, alteration of circadian rhythms, body mass index, calf circumference, thigh circumference, abdominal circumference) in the Mugello study oldest old.
METHODS: In 399 noninstitutionalized nonagenarians (291 women), whole blood cells, mean platelet volume, C-reactive protein, uric acid, gamma-glutamyl trans…

Based on recent studies, a surprising association between Takotsubo syndrome (TS) and cancer drawn substantial attention [1, 2]. Sattler K and co-workers [2] reported that cancer patients were prone to TS, as well as TS population were easy to suffer malignancies tumour. What acutely links behind the two diseases remain poorly known. These findings bring about whether TS share a common signaling pathway with the development of cancer.
