Circulate Health Publishes Results of Multiomics Study Demonstrating Impact of Therapeutic Plasma Exchange on Biological Age in Aging Cell
First-of-its kind trial shows that therapeutic plasma exchange combined with intravenous immunoglobulin reduced biological age on average by 2.6 years, as measured by multi-omics biomarkers
NOVATO, Calif., May 28, 2025 /PRNewswire/ -- Circulate Health, the company dedicated to harnessing the potential of therapeutic plasma exchange (TPE) to advance human healthspan and lifespan, today announces the publication of a single blind, human clinical trial in Aging Cell. This groundbreaking study, led by researchers from Circulate and the Buck Institute for Research on Aging provides promising early data on the impact of TPE on biological age, supporting its potential for new disease and longevity applications.
'Unfortunately, most so-called 'longevity interventions' lack proven effectiveness in humans. By conducting clinical trials, we aim to change that—this study marks the first step in demonstrating that plasma exchange can significantly improve key mechanisms of biological aging,' commented Dr. David Furman, senior author of the Aging Cell paper.
Therapeutic plasma exchange is a procedure that separates, removes, and replaces patient plasma to treat certain diseases. Multi-omics Analysis Reveals Biomarkers that Contribute to Biological Age Rejuvenation in Response to Therapeutic Plasma Exchange, investigated how TPE impacts biomarkers associated with biological age, including changes across the epigenome, proteome, metabolome, glycome, and immune system, alongside physical measures like balance and strength. Research participants were assigned one of four different treatment groups: 1) biweekly TPE, 2) biweekly TPE with intravenous immunoglobulin (IVIG) 3) monthly TPE or 4) a control group.
The study found:
'This is the first interventional multi-omics study to examine the effectiveness of therapeutic plasma exchange modalities,' said Brad Younggren, MD, CEO and Co-founder of Circulate. 'Our findings show that plasma exchange and intravenous immunoglobulin are a powerful tool for biological age rejuvenation and provide compelling evidence that targeted plasma interventions can impact age-related molecular changes.'
'In this study, we examined thousands of molecular signatures to pinpoint key drivers of rejuvenation. Our characterization builds a better understanding of which baseline biomarkers are predictive of treatment response and lays a foundation upon which we can build personalized intervention plans for patients in the future,' said Eric Verdin, MD, President and CEO of the Buck Institute and Co-founder of Circulate. 'We are excited to expand our research to larger populations, increase access to these treatments for eligible patients, and continue to identify areas of unmet need where these therapies can make a meaningful difference.'

Success or strike out? A's a boon to some local business, others left waiting for major league momentum
Some West Sacramento businesses are booming, others not so much since A's arrival Some West Sacramento businesses are booming, others not so much since A's arrival Some West Sacramento businesses are booming, others not so much since A's arrival WEST SACRAMENTO – Before the Athletics' three-year relocation to Sutter Health Park, West Sacramento small businesses were pitching big ideas to cash in on the Major League momentum from the first day the move was announced. Now, two months into the season, some call it a success. Some call it a strikeout, still waiting on the business boom they were hoping for. How helpful the team has been for the business depends on who you ask. Drake's: The Barn, basically next-door neighbors with the A's, is hitting it out of the park. "This is very much our A's pre-game pop," said Bia Hoskins, general manager of Drake's, as she gestured to a packed house on Friday night, an hour before first pitch. Things have been busy at Drake's, where big league ball has brought big league business. "We've definitely seen an uptick in that walk-in traffic leading up to A's games. On a home week, we definitely plan ahead," said Hoskins. "We've benefited for sure from the team being here, people wanting a quick bite and drink before they head to the game. It's been really impactful for us and we've really enjoyed it." But other small businesses just blocks from the ballpark are still waiting for their major league moment. "We see a little uptick in business. But nothing, nothing like we anticipated," said Jeff "Fro" Davis, owner of Treehouse Cafe. Treehouse Cafe changed their hours and offerings to welcome an A's crowd. It hasn't materialized like Davis had hoped. "We had a full outside bar, live bands. But it didn't come to fruition like we thought. Right now, on weeknights, I have one cook and a bartender. And that's all we need," Davis said. Davis said he had to scale back the extra staffing he hired, but is still basing his hours around each A's home game. Live music now is limited to the weekend games. "People are barely walking down the street in front of us here. We are not seeing the impact like we thought we would," Davis said. "It depends on the brand. When the Yankees were in town, we were packed. I'm looking forward to the Giants coming to town Fourth of July weekend." About 15 minutes from the stadium in Southport, West Sac Sports Bar and Grill invested in renovations, trying to become a home base for A's fans away from the stadium. Unfortunately, former owner Shawn Mason says it didn't pay off. Mason tells CBS13 he sold his bar to a new owner last week after 11 years in business. He said it's because that expected business boom never came and an A's losing record hasn't helped. What's been a success for some has been a strikeout for others. "But, it is what it is, and we are just lucky to be a part of the scene," Davis said. So far this season, A's attendance has been good, not great. The average for ticketed fans is just over 10,000. But the A's have only put up four sellout crowds, the home opener versus the Chicago Cubs and the entire three-game series versus the New York Yankees. The lowest attended game of the season to date was on Tuesday, June 3, versus the Minnesota Twins, with 8,487 tickets sold.

Analysts unveil bold forecast for Alphabet stock despite ChatGPT threat
Analysts unveil bold forecast for Alphabet stock despite ChatGPT threat originally appeared on TheStreet. You typed in a question and clicked a few links, and Google could get paid if you landed on an ad. For years, that simple cycle helped turn Google into a trillion-dollar titan. But now, that model is under threat. 💵💰💰💵 AI-powered chatbots like OpenAI's ChatGPT are rapidly changing how people find answers. Instead of browsing through links, users are getting direct summaries on AI. These 'zero-click' searches quietly erode the economics that built the modern internet. The number of users is growing fast. OpenAI CEO Sam Altman said in April that ChatGPT already has 'something like 10% of the world" in terms of users, pegging the number closer to 800 million, Forbes reported. Even Google seems to know it. It's giving AI answers, called AI Overviews, right at the top of the page. "What's changing is not that fewer people are searching the that more and more the answers to Google are being answered right on Google's page. That AI box at the top of Google is now absorbing that content that would have gone to the original content creators," Cloudflare CEO Matthew Prince said in a CNBC interview. Alphabet () , Google's parent company, isn't showing any cracks just yet. In April, the company posted first-quarter revenue of $90.23 billion, topping Wall Street expectations. Earnings per share came in at $2.81, far above the forecasted $ the backbone of Google's business, brought in $66.89 billion, accounting for nearly three-quarters of total revenue. Its 'Search and other' segment rose almost 10% year over year, hitting $50.7 billion. Meanwhile, Google's own AI tools are starting to show traction. AI Overviews now has 1.5 billion users per month, up from 1 billion in October, the company said. So far, the numbers suggest that AI isn't cannibalizing Google's business yet. Bank of America remains bullish on Alphabet stock. The firm reiterated a buy rating and a price target of $200, which implies a potential 15% upside from current levels, according to a recent research report. The firm said in May, Google's global average daily web visits held steady at 2.7 billion, unchanged from the previous month and down 2% from a year earlier. ChatGPT, meanwhile, saw a 3% month-over-month increase to 182 million, marking a 105% jump the U.S., Google traffic slipped 2% year-over-year to 524 million daily visits, while ChatGPT surged 112% over the same period to 26 million. Although Google has highlighted the growing reach of its AI Overviews, analysts are uncertain whether it's translating into more traffic. 'So far, we are not seeing a lift in Google traffic from AI Overviews expansion, though we think the search experience is much improved,' the analysts wrote. The competition is real. Google's global search share also edged down in May, falling 8 basis points month-over-month and 123 basis points year-over-year to 89.6%, according to Statcounter. Still, Bank of America analysts remain optimistic on Alphabet stock. "While ChatGPT's traffic continues to grow rapidly, we think Google remains well-positioned given its scale, multi-product reach, data assets, and robust monetization infrastructure," the analysts said. "AI can expand overall search monetization by better understanding the intent behind complex and long-tail queries that were previously hard to monetize," they added. Morningstar's Malik Ahmed Khan echoed that sentiment, saying Alphabet's diverse revenue streams and global exposure should cushion any hits, even as regulatory and AI risks mount, according to a May research report. Alphabet stock closed at $174.92 on June 6.
