Which embryos have the best opportunity to develop into a viable pregnancy?
           
A new technology provides a surprising answer or challenge in the field of IVF is selecting the single best embryo which is likely to result in a live birth. Currently, embryologists must remove the embryo from a standard incubator to perform 2 or 3 short evaluations of the developing embryo under the microscope, at fixed time-points over 3-5 days, in order to assess embryo quality prior to transferring an embryo to the patient.
  
The EmbryoScope(R) Time-lapse system generates a movie allowing embryologists to monitor various characteristics of the embryo development over the entire incubation period, while maintaining optimum incubation conditions in a state-of-the-art incubator.

According to breakthrough scientific results, embryos which exhibit irregular division patterns have a much lower pregnancy potential. The results were made available online on August 27 in the journal Fertility & Sterility, and confirms the benefits of implementing the EmbryoScope(R) ime-lapse system from the Danish company Unisense FertiliTech A/S.

A clinical multi-center study from Equipo IVI, Spain, Maigaard clinic and Brædstrup Hospital in Denmark, including a total of 5225 embryos, reports significantly reduced implantation of embryos which have a second division cycle occurring in less than 5 hours (considered direct cleavage), compared  to the implantation probability of "normally" developing embryos. The embryos with a short second division cycle will simply not have enough time for DNA replication, which is a prerequisite for a normal cell division.

Nearly 14% of all examined embryos exhibited this division pattern and according to the study will have a greatly reduced probability of resulting in a viable pregnancy. For both patients and fertility clinics it is important to decrease transfer of embryos with low very low implantation potential. With this new technology, clinics now have objective criteria with which to identify the embryo with a higher chance of implanting allowing more successful single embryo transfer cycles.

Marcos Meseguer, co-author of the paper and senior embryologist at Equipo IVI in Valencia, states "The ability to identify abnormal development events in embryos is certainly a key advantage of using time-lapse systems such as the Embryoscope(R) allowing us to improve our patient treatment".

The improvement potential of implementing time-lapse systems is increasing constantly as scientists discover new information about early human embryo development and more than 180 IVF clinics are using the Embryoscope(R) technology worldwide.

Unisense FertiliTech A/S was founded in 2003 to develop technology to improve human embryo assessment in assisted reproduction. Unisense FertiliTech has developed, and manufactures the EmbryoScope(R)- a unique Time-lapse system facilitating improved IVF treatment, flexible work routines and effective communication through comprehensive documentation of embryo development and evolving improvements in selection. The System is FDA 510(k) cleared and CE marked as a Class II medical device.

Opening of public lands for agri-developments

For many decades, vast tracts of forest lands are damaged across the Philippines. These are either the handiwork of nature like soil erosions, landslides, tremors or they're simply man-made due to humans' greed for immediate cash if only to survive. By all means, those who are within the proximity of the forests are free to do whatever they thought was best for them to survive or earn fast cash.  Notably, the most common practice that upland dwellers do is the cutting of firewood, slash-and-burn farming to plant crops even if these activities run counter to established forestry regulations that forbid them from doing these activities without permission from the authorities. Without a land of their own, they have to do it anyway. While some armed groups would simply engage themselves in illegal logging activities for profits. Forestry reports said that they even encroach on other's logging concessions to cut trees for sale to interested buyers. When I was working with the Mi

China is to blame for the pandemic spread

Image
Had the Chinese government taken the initiative or done enough to immediately contain the novel Coronavirus from spreading waywardly into other areas, this pandemic wouldn't have gone too far to pester other countries like Italy, the United States and the Philippines whose governments had declared a lockdowns thus causing extreme fears among the people, not to mention the derailments of some economies worldwide. But the provincial government, where Wuhan is an integral part of, acted too late to lockdown the place. The local government in Wuhan should have prevented residents from getting out, especially those who were infected by the virus. Sorry to say this, but the Wuhan government officials were lackadaisical in their approach to the health dilemma, thinking that the problem was just an ordinary matter which didn't require much attention. Until the problem got worse resulting to some deaths in the area had they known of Covid-19's serious impacts on the health of innoce
