We evaluated carryover effects of hydroperiod length (50-62 days) on amphibian survival, developmental rates, and locomotor performance using a model organism, the wood frog (Rana sylvatica), through aquatic and terrestrial mesocosm experiments with individual tests of locomotor performance. We found that shorter hydroperiods (50 days) had low larval survival (0.44 ± 0.03) compared to the 62-day hydroperiod (0.91 ± 0.09) and increased developmental rates, resulting in smaller sizes at metamorphosis. We did not find evidence of carryover effects on terrestrial survival three months post-metamorphosis with all hydroperiod treatments showing high terrestrial survival (0.88 ± 0.07). However, post-metamorphic frogs from the longer hydroperiod treatments grew faster and larger compared to individuals from shortest hydroperiods and performed significantly better during endurance trials at 18 °C. Disentangling complex carryover effects across multiple life stages in species with high phenotypic plasticity can shed light on the physiological capacity of species to respond to changing environments and inform mechanistic predictions of persistence in the face of anthropogenic stressors.Transcription factors are inextricably linked with histone deacetylases leading to compact chromatin. The Forkhead transcription factor Fkh1 is mainly a negative transcriptional regulator which affects cell cycle control, silencing of mating-type cassettes and induction of pseudohyphal growth in the yeast Saccharomyces cerevisiae. Markedly, Fkh1 impinges chromatin architecture by recruiting large regulatory complexes. Implication of Fkh1 with transcriptional corepressor complexes remains largely unexplored. In this work we show that Fkh1 directly recruits corepressors Sin3 and Tup1 (but not Cyc8), providing evidence for its influence on epigenetic regulation. We also identified the specific domain of Fkh1 mediating Sin3 recruitment and substantiated that amino acids 51-125 of Fkh1 bind PAH2 of Sin3. Importantly, this part of Fkh1 overlaps with its Forkhead-associated domain (FHA). To analyse this domain in more detail, selected amino acids were replaced by alanine, revealing that hydrophobic amino acids L74 and I78 are important for Fkh1-Sin3 binding. In addition, we could prove Fkh1 recruitment to promoters of cell cycle genes CLB2 and SWI5. Notably, Sin3 is also recruited to these promoters but only in the presence of functional Fkh1. Our results disclose that recruitment of Sin3 to Fkh1 requires precisely positioned Fkh1/Sin3 binding sites which provide an extended view on the genetic control of cell cycle genes CLB2 and SWI5 and the mechanism of transcriptional repression by modulation of chromatin architecture at the G2/M transition.<br />Tibial shaft fractures are common occurrence in children and surgical treatment is sometimes required, particularly in unstable or open fractures, and in polytrauma. The aim of this study was to investigate the available evidence on the efficacy and safety of flexible intramedullary nailing (FIN) for both open and closed tibia fractures in children, exploring the main surgical outcomes and rate of complications.<br />Pubmed/Medline, Scopus and Cochrane Central databases were searched following the PRISMA guideline. Studies reporting on the outcomes of FIN for paediatric tibia shaft fractures were included. Weighted means were evaluated for surgical outcomes. Meta-analysis of proportion and odd ratios were used to analyse total complication rates and differences between open and closed fractures.<br />Twenty-eight studies (835 patients) were included; the mean age was 11.0 ± 3.0years. The mean follow-up was 22.5 ± 13.5months; the mean time to full weight-bearing was 7.5 ± 3.7weeks. The total complication rate was28.1% (minor = 20.7%, major = 6.3%); this was greater in open fractures (13.6% vs 5.1%, p = 0.007). The rate of union was 97.5%, with a mean time to union of 11.9 ± 7.2weeks. Malunion was found in 8.5% cases, delayed union in 3.8%, non-union in 1.4%, symptomatic hardware in 5.1%, leg-length discrepancy in 5.0%, superficial infections in 2.3%, deep infections in 1.0%, compartment syndromes in 1.4%, and refracture in 0.2%. Almost all patients returned to unrestricted physical activity.<br />FIN offers excellent outcomes for the treatment of paediatric tibia shaft fractures. Patients presenting with an open fracture have a higher but acceptable complication rate. Comparative studies are needed to clarify if other treatments have superior outcomes.<br />FIN offers excellent outcomes for the treatment of paediatric tibia shaft fractures.

Treatment of a hip fracture nonunion allows for the choice between hip preservation or arthroplasty. The goal of this study was to examine outcomes of hip-preservation nonunion surgery METHODS Patients who underwent hip preservation for a fracture nonunion of the femoral neck, intertrochanteric and subtrochanteric region to 1cm below the lesser trochanter over a 10-year period were identified in our nonunion registry. Patients were followed for a minimum of 1year. [https://www.selleckchem.com/products/spautin-1.html Spautin1] Functional outcomes were recorded at follow-up visits. For comparison regarding surgical and hospital outcomes, a group of 23 patients who underwent conversion total hip arthroplasties (cTHA) at the same academic medical center was reviewed. Quality measures such as length of stay, reoperation, and complications were collected. All statistics analysis utilized IBM SPSS 25 (Armonk, NY) RESULTS Thirty patients who underwent 30 hip-preserving nonunion surgeries were analyzed and compared with 23 cTHA patients.
