Blood pressure medications impact brain function — ScienceDaily


Printed in Science, College of Minnesota Medical College researchers discovered that blood strain medicines have an unanticipated impact on the mind.

The analysis staff found that medicine used to deal with blood strain unexpectedly enhance the impact of opioids that the mind naturally produces. This could fine-tune the perform of a selected mind circuit and counteract the addictive properties of opiates like fentanyl, that are used to deal with ache.

“Our findings recommend a brand new technique to spice up opioid signaling within the mind in a approach that’s protecting and helpful, with a really low threat of dependence or habit,” mentioned Patrick Rothwell, PhD, an assistant professor of neuroscience on the U of M Medical College and Medical Discovery Workforce on Habit.

The research centered on angiotensin-converting enzyme (ACE), which has lengthy been identified to manage blood strain. Nonetheless, little is thought in regards to the perform of ACE within the mind.

Primarily based on the research findings, Rothwell recommends additional analysis on ACE inhibitors, a secure class of medication used to manage blood strain. ACE inhibitors have the potential to be redesigned to deal with mind circumstances.

This analysis was funded by Minnesota’s Discovery, Analysis, and Innovation Economic system (MnDRIVE) initiative, and the Nationwide Institute on Drug Abuse. The mission was led by Brian Trieu, an MD/PhD candidate working within the Rothwell lab.

In collaboration with Dr. Swati Extra from the Middle for Drug Design within the School of Pharmacy, Rothwell and College researchers are creating new ACE inhibitors with a view to optimize their impact on mind perform. This ongoing effort is supported by a School Analysis Improvement Grant from the Workplace of Tutorial Medical Affairs.

Many young people with obesity have high blood pressure


Almost half of seven,493 adolescents and kids with weight problems who took half in a pediatric weight administration initiative had hypertension, a examine revealed in The Journal of Medical Hypertension discovered. Researchers mentioned pediatric weight administration applications ought to have uniform BP assessments.

New optical tweezers put on the pressure to change color — ScienceDaily


One large stumbling block within the area of photonics is that of coloration management. Till now, to regulate coloration, i.e. the wavelength of sunshine emission, researchers must alter the chemical construction of the emitter or the focus of the solvent — all of which require direct contact, vastly limiting their utility.

“Such situations make it not possible to alter coloration rapidly, use it as a lightweight supply in microscopic areas like a cell, or in closed methods the place trade just isn’t an possibility,” says Yasuyuki Tsuboi and professor of the Division of Chemistry, Osaka Metropolis College. With “optical tweezers,” a know-how he developed in earlier analysis, Prof. Tsuboi led a staff of researchers to point out it doable to regulate the luminescence coloration remotely, utilizing solely the impact of sunshine stress.

Their findings have been just lately printed on-line within the German worldwide journal Angewandte Chemie Intl.

For years, Professor Tsuboi and his colleagues have been conducting analysis on a know-how that may seize and manipulate nano- and micrometer-sized supplies with a laser. In exploring this “optical tweezers” know-how, they discovered that when a silicon crystal with a particular needle-shaped nanostructure, known as black silicon, was submerged in a pattern answer, the optical area enhancement impact of the nanostructure trapped a perylene-modified polymer, inflicting an area focus of the answer to extend and kind an combination of polymers.

“When the focus of the perylene will increase, it kinds a dimeric excited advanced known as an excimer,” explains lead creator Ryota Takao. These excimers emit fluorescence that adjustments coloration relying on the diploma of focus.

That is what the analysis staff investigated in prior trapping experiments that didn’t make use of a trapping laser. Right here they discovered that because the laser beam depth elevated, gentle stress did as nicely, which prompted the focus of the polymer combination on the black silicon to turn out to be denser — and vice versa.

“We noticed the colour of the fluorescence emitted by the polymer combination change in response to this,” explains Prof, Tsuboi, “with low intensities producing blue, after which altering to inexperienced, yellow, inexperienced yellow, to orange because the depth will increase.” Because the laser depth is what’s being managed, the colour change is totally reversible and capable of be accomplished remotely.

Whereas the analysis remains to be in its infancy, it depends on excited complexes and excitation power switch, which suggests potential purposes in ultraviolet and near-infrared areas, along with the seen realm. The analysis staff is at present selling additional analysis within the course of encapsulating the perylene-modified polymer answer for use as a lightweight supply in micromachine elements and intracellular bioimaging.

In ‘attacking the pressure’ of predictions, BYU women cruise to 1st regular-season title since 2016


The BYU Cougars rejoice after successful a West Coast Convention sport in opposition to the Gonzaga Bulldogs on the Marriott Heart in Provo on Saturday, Feb. 19, 2022. (Mengshin Lin, Deseret Information)

Estimated learn time: 4-5 minutes

PROVO — After a thunderous, emotional win over Gonzaga within the remaining house sport of the common season, BYU girls’s basketball had yet one more formality left: win the West Coast Convention outright championship.

The formality got here to a head shortly in Stockton, California.

Shaylee Gonzales poured in 18 factors, eight rebounds, three assists and 4 steals, and Paisley Harding added 14 factors and 4 rebounds as No. 19 BYU rolled to a 82-52 win at Pacific on the Spanos Heart to clinch the Cougars’ first West Coast Convention regular-season title in seven years.

Lauren Gustin added 11 factors and 13 rebounds — her league-high 14th double-double of the season — for BYU (25-2, 15-1 WCC), and Tegan Graham had 12 factors and 5 assists for the Cougars.

It is the primary outright regular-season convention title for BYU (25-2, 15-1 WCC) because the 2015-16 season, and the second general since becoming a member of the West Coast Convention in 2011. BYU additionally received convention regular-season titles below head coach Jeff Judkins in 2005-06, 2006-07, and 2010-11 as members of the Mountain West.

Maybe the toughest half for the Cougars, who ranked No. 8 within the NET with a mean margin of victory of 20.9 factors, was how they received that league title: from the entrance. Judkins knew his workforce had the prospect to do one thing particular.

“I realized a very long time in the past that you do not cover from strain; you assault it,” Judkins mentioned. “When the season began, we had our targets and after we bought picked first, I allow them to know they’ve a bullseye on their again.

“You have to methods to go: both relish it and reap the benefits of it and win a championship, or fold. I do know my workforce, they usually’re rivals; they took that problem actually arduous.”

The Cougars had been predicted to win the WCC title a 12 months after a bevy of seniors like Harding, Graham, Sara Hamson and Maria Albiero returned from an additional 12 months of eligibility offered by the NCAA because of the COVID-19 pandemic. However BYU did not simply exit and win — the workforce rolled to the championship, sweeping runner-up Gonzaga and taking over all challengers (aside from one highway sport at Portland) to pummel groups by double digits, evening in and evening out.

Saturday was no exception. The one draw back to the afternoon was having to clinch the title and lift the trophy in Pacific’s fitness center, and never at house in entrance of a rising era of Cougar followers within the Marriott Heart.

BYU opened the sport on a 16-2 run, led by 5 factors from Harding and 4 factors apiece from Gonzales and Gustin, to spoil the Tigers’ senior day early.

Harding capped a 13-3 run, bridging the primary two quarters with a driving layup that pushed the Cougars’ result in 29-9 lower than two minutes into the second quarter. Gonzales had 12 factors and 7 rebounds within the first half, Harding added 9 factors, two assists and two steals, and Tegan Graham provided 9 factors and 5 assists as BYU took an amazing 50-20 lead into the break.

Even Arielle Mackey-Williams, the freshman reserve from New Zealand had, 7 factors on 3-of-3 capturing within the first half — simply 2 factors off her profession excessive because the Tigers shot simply 25% from the sphere within the first half.

Gonzales took any doubt away from the sport early, not simply offensively, however with a game-high 4 steals and three assists with only one turnover.

“The factor about Shaylee is she’s so targeted on desirous to be one of the best participant,” Judkins mentioned of his star sophomore. “It is the toughest place on the workforce, however I believe her and Paisley this 12 months labored so effectively collectively.

“Shaylee does a number of issues; she scores a number of factors, however she does a number of different issues defensively, will get a number of steals, deflections, rebounds, and she or he’s a wonderful passer.”

It was a rout early and a rout usually — one which shut down the West Coast Convention’s web site, which was streaming the sport, just some minutes after tipoff.

The preseason favourite Cougars had waited all 12 months to clinch their first convention title in seven years, they usually weren’t ready any longer, leaping out to a 71-32 lead after 4 quarters earlier than Judkins put within the reserves to seal the win.

Have been the Cougars excellent? Not hardly, and the loss to Portland will present that. However they’re going to even be the favorites to win the convention match in Las Vegas — and Judkins plans to assault that week in Sin Metropolis like his workforce did the common season.

“Did we slip up? Yeah, one time. However I believe after we misplaced that sport (at Portland) after which received at Gonzaga, I believe it set the tone for our workforce and what they may accomplish,” Judkins mentioned. “I’ve by no means been a coach to shrink back from strain, and my workforce isn’t that method, both.

“We’re favored to win the match, too, and we will exit and battle there, too.”

BYU will open the WCC Match semifinals Monday, March 7, tipping off at 1 p.m. MST on the Orleans Area in Las Vegas.
