Carbohydrate–protein ingestion during recovery from prolonged exercise in man

Evidence supports that the ingestion of carbohydrate solutions in the post-exercise period can facilitate the restoration of exercise capacity both through providing the fluid necessary for rehydration and through stimulating carbohydrate storage. The accrual of this evidence has now established many components of the optimal carbohydrate feeding strategy during recovery and further progress has been sought through investigating the potential influence of other macronutrients. Specifically, combined ingestion of protein and carbohydrate may promote a more rapid re-synthesis of endogenous glycogen stores than when either nutrient is ingested in isolation. This possibility has led to speculation that ingestion of a mixed carbohydrate-protein solution (CHO–PRO) might restore the capacity for physical exercise more completely during a short-term recovery than when a matched quantity of carbohydrate alone is ingested. However, evidence in support of this hypothesis is not yet available and the present series of studies will therefore attempt to directly examine the effects of CHO–PRO ingestion on recovery of exercise capacity.

Taxonomic voucher specimens for study of bee communities in intensively managed Douglas-fir forests in the Oregon Coast Range

Understanding how pollinators respond to anthropogenic land use is key to conservation of biodiversity and ecosystem services, but few studies have addressed this topic in coniferous forests, particularly those managed intensively for wood production. This study reports on voucher material generated as part of Zitomer et al. (2023), that assessed changes in wild bee communities with time since harvest in 60 intensively managed Douglas-fir (Pseudotsuga menziesii) stands in the Oregon Coast Range across a gradient in stand age spanning a typical harvest rotation (0-37 years post-harvest). We additionally assessed relationships of bee diversity and community composition to relevant habitat features, including availability of floral resources and nest sites, understory vegetation characteristics, and composition of the surrounding landscape. Specimens were collected using a combination of passive sampling methods-blue vane traps and white, blue, and yellow bowl traps- and hand-netting and were identified to the lowest possible taxonomic level by A.R. Moldenke and L.R. Best. Four hundred and ten taxonomic voucher specimens were deposited into the Oregon State Arthropod Collection (Accession# OSAC_AC_2023_01_09-001-01) to serve as a reference for future research

Comparative efficacy of long-acting β2-agonists as monotherapy for chronic obstructive pulmonary disease: a network meta-analysis

Long-acting β2-agonists (LABAs) have demonstrated efficacy in patients with COPD in clinical trials. The purpose of this study was to assess the comparative efficacy of all available dosages of all LABA monotherapies using a network meta-analysis
