26S proteasome abundance is tightly regulated at multiple levels, including the elimination of excess or inactive particles by autophagy. In yeast, this proteaphagy occurs upon nitrogen starvation but not carbon starvation, which instead stimulates the rapid sequestration of proteasomes into cytoplasmic puncta termed proteasome storage granules (PSGs). Here, we show that PSGs help protect proteasomes from autophagic degradation. Both the core protease and regulatory particle sub-complexes are sequestered separately into PSGs via pathways dependent on the accessory proteins Blm10 and Spg5, respectively. Modulating PSG formation, either by perturbing cellular energy status or pH, or by genetically eliminating factors required for granule assembly, not only influences the rate of proteasome degradation, but also impacts cell viability upon recovery from carbon starvation. PSG formation and concomitant protection against proteaphagy also occurs in Arabidopsis, suggesting that PSGs represent an evolutionarily conserved cache of proteasomes that can be rapidly re-mobilized based on energy availability.

Lacrosse and ice hockey are quickly growing in popularity, while football remains the most popular sport among high school student-athletes. Injuries remain a concern, given the physical nature of these contact sports.
To describe the rates and patterns of injuries sustained as a result of intentional player contact in United States high school boys’ football, ice hockey, and lacrosse.
Descriptive epidemiology study.
We conducted a secondary analysis of High School RIO (Reporting Information Online) data, including exposure and injury data collected from a large sample of high schools in the United States from 2005-2006 through 2015-2016. Data were analyzed to calculate rates, assess patterns, and evaluate potential risk factors for player-to-player contact injuries.
A total of 34,532 injuries in boys’ football, ice hockey, and lacrosse occurred during 9,078,902 athlete-exposures (AEs), for a rate of 3.80 injuries per 1000 AEs in the 3 contact sports of interest. The risk of injuries was found to be greater in competition compared with practice for all 3 sports, with the largest difference in ice hockey (rate ratio, 8.28) and the smallest difference in lacrosse (rate ratio, 3.72). In all 3 contact sports, the most commonly injured body site in competition and practice caused by both tackling/checking and being tackled/checked was the head/face. However, a significantly greater proportion of concussions sustained in football were the result of tackling compared with being tackled (28.2% vs 24.1%, respectively). In addition, a significantly greater proportion of concussions were sustained in competition compared with practice for all 3 sports.
This study is the first to collectively compare injury rates and injury patterns sustained from intentional player-to-player contact in boys’ high school football, ice hockey, and lacrosse. Notably, there was a relatively high risk of injuries and concussions during football practices.

In the title compound, C21H25NO2, the piperidine ring adopts a twisted boat conformation characterized by puckering parameters θ = 89.5 (1) and ϕ = 257.5 (2)°. The phenyl groups are located in equatorial and axial positions on the central piperidine ring, while the methyl group is in an equatorial position. The dihedral angle between the phenyl rings is 49.8 (1)°. An intramolecular C—H⋯O interaction occurs. The crystal structure features weak intermolecular C—H⋯O interactions and a stabilizing intermolecular C—H⋯π contact involving the axial phenyl ring.
