Exposure to phthalates during pregnancy can affect a newborn’s brain development, study finds
после анального секса

Phthalates — the synthetic chemicals used in everyday products for food packaging, personal care, toys and more — have been linked to abnormal neurological development in infants.

Now, scientists may have discovered a biological pathway for how this phenomenon could occur. Researchers found that in utero exposure to phthalates is linked with altered metabolism of neurotransmitters and amino acids involved in brain maturation, according to a study published Wednesday in the journal Nature Communications.

The report is the first to use untargeted metabolomics — the study of all small molecules or metabolites in a biological system — to connect a mother’s phthalate exposure to a newborn’s metabolites, and those metabolites to neurological development, said senior study author Dr. Donghai Liang via email.
“This represents an important step forward in understanding how prenatal chemical exposures shape infant development at the molecular level,” added Liang, an associate professor of environmental health at Emory University’s Rollins School of Public Health in Atlanta.

First introduced in the 1920s, phthalates are used to make plastics softer and more flexible, primarily in polyvinyl chloride (PVC) products such as vinyl flooring, medical devices, children’s toys, food packaging or shower curtains. The chemicals also help lubricate substances and carry fragrances in various personal care products including deodorant; nail polish; perfumes; hair gels, sprays or shampoos; soaps; and body lotions.

Phthalates are also endocrine disruptors that have been linked to preterm birth, infant genital abnormalities, childhood obesity, asthma, cancer, cardiovascular issues, and low sperm count and testosterone in men.

“We conducted this study because phthalates are everywhere in our daily lives,” Liang said, hence their nickname “everywhere chemicals.”

Harming infant health
The findings are based on mother-newborn pairs enrolled in the Atlanta African American Maternal-Child Cohort between 2016 and 2018. In urine samples collected from 216 mothers between eight weeks and 14 weeks of gestation at visit one and 145 participants between 24 and 30 weeks’ gestation at visit two, the authors measured eight phthalate metabolites. Participants were around age 24 on average, and their levels of some phthalate metabolites were higher than the average determined by the National Health and Nutrition Examination Survey.

Within a day or two of birth, the authors collected the babies’ blood via a heel stick.

The team found prenatal phthalate levels were associated with lower levels of tyrosine, an amino acid and precursor to the thyroid hormone thyroxine. Thyroxine was also abnormally low in those with in utero phthalate exposure, and low thyroxine has been previously associated with greater vulnerability to illness and neurodevelopmental issues in newborns, the authors said. Tyrosine is also a precursor to the neurotransmitters dopamine, norepinephrine and epinephrine, all of which partly contribute to the body’s fight-or-flight response. Low levels of these neurotransmitters can lead to various problems, including anxiety, depression and trouble focusing.

Prenatal phthalate exposure was also linked with lower levels of the essential amino acid tryptophan, which converts into 5-hydroxytryptophan (or 5-HTP), which then turns into serotonin. Both 5-HTP and serotonin were also low. Serotonin has several critical roles in the body, including mood regulation, sleep, learning, memory, digestion and the body’s response to stress. Previous research has linked low serotonin with mood disorders such as depression and anxiety, sleep problems, and digestive issues.

Xavier completes thrilling comeback, Mount St. Mary’s advances as men’s First Four comes to a close
changenow
Wednesday saw the men’s First Four come to a close which means only one thing: the 64-team bracket is officially set following No. 11 Xavier’s thrilling come from behind win over No. 11 Texas and No. 16 Mount St. Mary’s victory over No. 16 American in Dayton, Ohio.

The Musketeers trailed by as many as 13 points, but their offense came alive in the second half behind guard Marcus Foster and forward Zach Freemantle to down the Longhorns 86-80.

The senior Foster scored a team-high 22 points while Freemantle, on his way to 15 points, threw down a dunk with a second left to seal the comeback win and ignite the fans at UD Arena, which is just over 50 miles away from campus in Cincinnati, Ohio.

With just under four minutes remaining, Xavier went on an 8-2 run to take a 78-74 lead, their first since the early going of the first half.

Musketeers head coach Sean Miller crowned Wednesday’s game as “one of the best” he’s been a part of.

“I thought we were dead in the water two different times,” Miller told the truTV broadcast after the game. “But that’s the one thing about our team — the resiliency of our group has always won out for us. Just when you thought we weren’t gonna make the tournament, we kept winning. Even in this game, just when you’re like, ‘It’s not gonna work out,’ we have a funny way of staying with it.”

The Longhorns did not go down without a fight as guard Tre Johnson scored a game-high 23 points in the loss.

Xavier will face No. 6 Illinois in the first round on Friday at the Fiserv Forum in Milwaukee.

A librarian ran off with a yacht captain in the summer of 1968. It was the start of an incredible love story
metamask
The first time Beverly Carriveau saw Bob Parsons, she felt like a “thunderbolt” passed between them.

“This man stepped out of a taxi, and we both just stared at each other,” Beverly tells CNN Travel today. “You have to remember, this is the ‘60s. Girls didn’t stare at men. But it was a thunderbolt.”

It was June 1968. Beverly was a 23-year-old Canadian university librarian on vacation in Mazatlan, Mexico, with a good friend in tow.

Beverly had arrived in Mazatlan that morning. She’d been blown away by the Pacific Ocean views, the colorful 19th-century buildings, the palm trees.

Now, Beverly was browsing the hotel gift store, admiring a pair of earrings, when she looked up and spotted the man getting out of the taxi. The gift shop was facing the parking lot, and there he was.

“I was riveted,” says Beverly. “He was tall, handsome…”

Eventually, Beverly tore away her gaze, bought the earrings and dashed out of the store.

“We locked eyes so long, I was embarrassed,” she says.

No words had passed between them. They hadn’t even smiled at each other. But Beverly felt like she’d revealed something of herself. She felt like something had happened, but she couldn’t describe it.
Beverly rushed to meet her friend, still feeling flustered. Over dinner in the hotel restaurant, Beverly confided in her friend about the “thunderbolt” moment.

“I told my girlfriend, ‘Something just happened to me. I stared at this man, and I couldn’t help myself.’”

Then, the server approached Beverly’s table.

“He said, ‘I have some wine for you, from a man over there.’”

The waiter was holding a bottle of white wine, indicating at the bar, which was packed with people.

As a rule, Beverly avoided accepting drinks from men in bars. She never felt especially comfortable with the power dynamic — plus, she had a long-term partner back in Canada.

“I had a serious boyfriend at home and thought my life was on course,” she says.
