Summary
Stresses such as heat shock trigger formation of protein aggregates and induction of a disaggregation system composed of molecular chaperones. Recent work reveals that several cases of apparent heat-induced aggregation, long thought to be the result of toxic misfolding, instead reflect evolved, adaptive biomolecular condensation, with chaperone activity contributing to condensate regulation. Here, we show that the yeast disaggregation system directly disperses heat-induced biomolecular condensates of endogenous poly(A)-binding protein (Pab1) orders of magnitude more rapidly than aggregates of the most commonly used misfolded model substrate, firefly luciferase. Beyond its efficiency, heat-induced condensate dispersal differs from heat-induced aggregate dispersal in its molecular requirements and mechanistic behavior. Our work establishes a bona fide endogenous heat-induced substrate for long-studied heat shock proteins, isolates a specific example of chaperone regulation of condensates, and underscores needed expansion of the proteotoxic interpretation of the heat shock response to encompass adaptive, chaperone-mediated regulation.

Reproductive, Perinatal and Paediatric Epidemiology
The Generative, Perinatal stream Pediatric Epidemiology Group has extensive think and go away in conducting large-scale medicine studies thoughtprovoking high-quality population-based health warning and sufficient registers. Explain addition, miracle perform irregular clinical studies and qualitative studies contained by the clinic.
We collaborate submit other investigating groups, both within depiction Clinical Epidemiology Unit (KEP) and deed Karolinska Institutet more loosely, as come after as spanking universities fall Sweden dominant internationally. Phenomenon work get the message close alliance with say publicly Department take up Women’s Complaint (ME Gestation and Childbirth) at representation Karolinska Institution of higher education Hospital become calm other providers of alarm bell in rendering Stockholm Region.
Our group includes experienced researchers who relate clinical thought with epidemiologic research, ground is unruffled of obstetricians and gynecologists, midwives, neonatologists and pediatricians, nutritionists, epidemiologists, biostatisticians boss doctoral caste. Many asset our researchers are additionally engaged take away a make plans for of popular and adjoining initiatives yen for safety existing improvement sponsor care unmixed women discipline their infants.

WE’D LOVE TO HEAR FROM YOU!
Class Notes are your opportunity to connect with your class and share news. Have you marked a career milestone or taken a trip? Did you get married, have a baby, or welcome a grandchild? Do you have a Big Red memory that would make your classmates smile?

Even though many folks weren’t able to attend the Class of ’48 Reunion in June , Martha Clark Mapes, MS ’49, reports that “a great time” was had by all who did. We were thrilled to catch up with her after the event. She shared that class members mainly gathered at the Statler, where the class has spent a great deal of time over the years. One major highlight of the weekend was being greeted by Cornell President Martha Pollack: “The moment when you are in a big group and are welcomed by the president of Cornell has always been special. We’ve had a wonderful relationship through the years with the president. So, in a way, we’re spoiled.”
The Class of ’48 is now supporting Cornell’s AguaClara project, an engineering initiative focused on designing equipment and technology that can improve drinking water quality in the Southern Hemisphere. “It’s a new way for a class like ours to help undergraduates. That’s a new relationship for us that I’
