The Integrated Chemists of the Philippines (ICP), the accredited professional organization of registered chemists and registered chemical technicians in the country, has the honor of announcing that the Outstanding Chemist of 2019, bestowed by the Professional Regulation Commission, is awarded to Ms Roselyn Usero.

Ms Usero holds a BS-Chemistry degree from the Colegio San Agustin and a master’s degree in environmental engineering from the University of St. La Salle, both in Bacolod City, Negros Occidental. She specializes in analytical chemistry, environmental engineering, industrial microbiology, aquaculture, and shrimp culture. She initially worked as a chemical analyst for numerous Bacolod-based companies and has also rendered service to her alma mater Colegio San Agustin as a part-time chemistry faculty. At present, Ms Usero is the laboratory head and manager of the Negros Prawn Producers Cooperative Analytical and Diagnostic Laboratory (NPPCADL) and teaches courses in the MS-Fisheries program at the Northern Negros State College of Science and Technology in Sagay City, Negros Occidental. In addition, she is a sought-after technical speaker in some notable gatherings in the country such as the Philippine Shrimp Congress and the Caraga Shrimp Forum and has also participated in various local and international conferences.

Ms Usero’s expertise in analytical chemistry and shrimp culture has tremendously helped the community in the Visayas region. She has written manuals on the successful shrimp culture techniques in Negros Island (2000) and the integration of the freshwater fish tilapia to the prawn culture system (2001). From 2004 to 2014, she received accolades in her numerous studies to mitigate the lethal white spot syndrome virus affecting the shrimp population in Negros island. In 2009, she was part of a team that assessed the water quality at Mambukal Mountain Resort, a popular tourist destination in the city of Murcia, southeast of Bacolod. In 2012, she helped conduct a study on the use of indigenous microorganisms as an alternative material in analyzing the biological oxygen demand in bodies of water. In 2017, Ms Usero developed a fry quality assessment criteria for the country’s shrimp culture.

Ms Usero also made significant contributions to the corporate growth and social footprint of NPPCADL. As its manager, NPPCADL became the first and only private laboratory in the Western Visayas region duly recognized by the Department of Natural Resources’s Environmental Management Bureau; received a Laboratory of Excellence certificate from the Environment Resource Associates in Colorado, USA for achieving 100% acceptable data for environmental parameters for water and wastewater; became a licensed soils laboratory by the Bureau of Soils and Water Management; and became the first laboratory in Negros island to be given an ISO/IEC 17025 accreditation. To cater to the needs of the community, Ms Usero utilized NPPCADL to provide high-quality analytical services to individuals or groups conducting research projects and to serve as an on-the-job training site for senior high school students from Bacolod and nearby localities.

Since 2013, Ms Usero has been the president of the ICP Bacolod Chapter. Through her utmost dedication, ICP Bacolod has prospered, manifested by a steady increase in the said chapter’s membership and the active attendance of its members during seminars and workshops that the chapter regularly organizes. She and her fellow officers have been actively promoting the chemistry profession in secondary schools, enticing the students to pursue a career in chemistry. In 2017, in partnership with the Technological University of the Philippines Visayas Campus, ICP Bacolod spearheaded a review session for examinees of the inaugural chemical technician licensure examination with the aim of professionalizing the employees of chemical laboratories in Negros island in response to the Chemistry Profession Act of 2015. Aside from being the lead organizer of this review session, Ms Usero also taught the analytical chemistry portion to the examinees. This review session was proven to be instrumental as it produced four of the Top 10 passers (two second-placers, one seventh-placer, one eighth-placer), and garnered an impressive 95% passing rate among those who have participated. The review session was conducted yet again in 2018, which resulted to even more licensed chemical technicians in the area.

This year’s Outstanding Chemist continues to use chemistry as a tool to build and enrich the lives of the community and the society at large. From your ICP family, congratulations Ms Roselyn Usero!

Could Reused Cooking Oil Trigger Breast Cancer Spread?

This article was written by Monica Beyer and was first published on the website Medical News Today on 31 March 2019.

A recent study in mice showed that reheated cooking oil might trigger cell changes that can promote late-stage breast cancer growth.

Researchers from the University of Illinois at Urbana-Champaign tested “thermally abused frying oil,” which is cooking oil that has undergone reheating to high temperatures multiple times, in laboratory mice and found that it increased metastatic breast cancer growth.

The team reported these findings in the journal Cancer Prevention Research.

The scientists fed all of the lab mice a low-fat diet for a week. Then, they gave some of the mice unheated fresh soybean oil for 16 weeks while the rest ingested thermally abused oil instead.

They chose to use soybean oil because the restaurant industry commonly uses it for deep frying.

To simulate breast cancer, they injected 4T1 breast cancer cells into a tibia of each mouse. These breast cancer cells are very aggressive and have a high rate of metastasis to multiple distant sites. As a result, they often appear in the lymph nodes, liver, and lungs.

The effects of reused oil

At 20 days after the injection of the tumor cells, there was a notable difference in the rate of metastatic growth between the two groups of mice. In the mice who had eaten thermally abused oil, the metastatic growth of the tibia tumors was four times greater than that of the tumors in the mice who consumed the fresh oil.

There were also more lung metastases in the former group. Lead researcher William G. Helferich, a professor of food science and human nutrition, noted that there were twice as many lung tumors, which were also more aggressive and invasive than those in the fresh-oil group.

“I just assumed these nodules in the lungs were little clones — but they weren’t,” says Helferich. “They’d undergone transformation to become more aggressive. The metastases in the fresh-oil group were there, but they weren’t as invasive or aggressive, and the proliferation wasn’t as extensive.”

Breast cancer statistics

Breast cancer occurs when cells in the breast grow out of control and form a tumor. If the cells are capable of invading the surrounding tissue or spreading to other areas of the body, doctors deem the disease to be malignant. Breast cancer is not exclusive to women — although it is rare, it can affect men as well.

Breast cancer rates in the United States have increased by 0.4 percent a year over recent years.

Why reheated oil may be bad

The repeated reheating of cooking oil changes its composition and releases acrolein, which is a toxic and potentially carcinogenic chemical.

Restaurants and other food outlets often reuse soybean oil multiple times before replacing it with fresh oil in the frying vats.
These factors are what led the researchers to investigate whether thermally abused oil could have any effect on breast cancer growth. Although the results are preliminary, they add to a knowledge base that will grow deeper as research in this area continues.

“Many cancer biologists are trying to understand what’s happening at metastatic sites to prime them for tumor growth,” notes co-lead author and graduate student Ashley W. Oyirifi. “We’re trying to add to this conversation and help people understand that it might not be just some inherent biological mechanism but a lifestyle factor. If diet provides an opportunity to reduce breast cancer survivors’ risk, it offers them agency over their own health”, she adds.

ICP Opens Chem Week 2019 with Seminar-Workshop on Chemical Waste Management

In celebration of this year’s National Chemistry Week, the Integrated Chemists of the Philippines (ICP) has organized a seminar-workshop on Practical and Cost-Effective Solutions to Laboratory Chemical Wastes held on 18 February 2019 at the Century Park Hotel in Manila. The event was well-attended by around 350 participants coming in from all parts of the country and representing diverse chemical sectors such as those working in the industry setting, educational institutions, government agencies, among others.

Five well-versed speakers kept the participants abreast on the latest developments and updates regarding the said topic. Mr Roger Evangelista (Environmental Management Bureau) discussed extensively the newly-updated regulations on how to effectively manage the hazardous wastes of chemical laboratories. He also informed the participants regarding the important role of the Department of Environment and Natural Resources in monitoring generators, transporters, and treaters of hazardous waste for the benefit of stakeholders and the community at large.

Mr Johanne Guilaran (Jefcor Laboratories) discussed extensively on the classification of hazardous wastes. He also mentioned ways on how laboratories can minimize the chemical wastes they generate. Ms Priscilla Alice Samonte (Nuevochem Specialties) gave practical information on how laboratory personnel would handle and store their chemical wastes. She stressed on the importance of segregation, using proper labels, and periodic inspection of stored wastes.

The Honorable Ma. Teresa Cayton (Board of Chemistry, Professional Regulation Commission) tackled on the proper disposal and treatment of chemical wastes. She also reported on the latest figures regarding laboratories who are faithfully complying with the Chemistry Profession Act of 2015, and showed some examples on how laboratories practice either good or bad waste management.

Lastly, Dr Glenn Alea (De La Salle University) emphasized on the safety practices that all laboratory personnel must follow while inside their respective chemical laboratory, such as the dynamic role of both employer and employees on laboratory safety, and how a company’s chemical safety manual must be regularly reviewed and updated.

Certainly, the participants gained a plethora of knowledge and practical wisdom on how to further improve their laboratory waste management. The ICP would like to express its most sincere gratitude to them for attending this event and making it successful.
