IMPORTIN-α3/MOS6 (MODIFIER OF SNC1, 6) is one of nine importin-α isoforms in Arabidopsis that recruit nuclear localization signal-containing cargo proteins to the nuclear import machinery. IMP-α3/MOS6 is required genetically for full autoimmunity of the nucleotide-binding leucine-rich repeat immune receptor mutant snc1 (suppressor of npr1-1, constitutive 1) and MOS6 also contributes to basal disease resistance. Here, we investigated the contribution of the other importin-α genes to both types of immune responses, and we analyzed potential interactions of all importin-α isoforms with SNC1. By using reverse-genetic analyses in Arabidopsis and protein-protein interaction assays in Nicotiana benthamiana, we provide evidence that among the nine α-importins in Arabidopsis, IMP-α3/MOS6 is the main nuclear transport receptor of SNC1, and that IMP-α3/MOS6 is required selectively for autoimmunity of snc1 and basal resistance to mildly virulent Pseudomonas syringae in Arabidopsis.Cyclin-dependent kinases (CDKs), the master regulators of cell division, are activated by different cyclins at different cell cycle stages. In addition to being activators of CDKs, cyclins recognize various linear motifs to target CDK activity to specific proteins. We uncovered a cyclin docking motif, NLxxxL, that contributes to phosphorylation-dependent degradation of the CDK inhibitor Far1 at the G1/S stage in the yeast Saccharomyces cerevisiae. This motif is recognized exclusively by S-phase CDK (S-CDK) Clb5/6-Cdc28 and is considerably more potent than the conventional RxL docking motif. The NLxxxL and RxL motifs were found to overlap in some target proteins, suggesting that cyclin docking motifs can evolve to switch from one to another for fine-tuning of cell cycle events. Using time-lapse fluorescence microscopy, we show how different docking connections temporally control phosphorylation-driven target degradation. This also revealed a differential function of the phosphoadaptor protein Cks1, as Cks1 docking potentiated degron phosphorylation of RxL-containing but not of NLxxxL-containing substrates. The NLxxxL motif was found to govern S-cyclin-specificity in multiple yeast CDK targets including Fin1, Lif1, and Slx4, suggesting its wider importance.
Pain management following transoral robotic surgery (TORS) varies widely. We aim to quantify opioid usage following TORS for oropharyngeal squamous cell carcinoma (OPSCC) and identify prescribing predictors.
Retrospective cohort study.
A consecutive series of 138 patients undergoing TORS for OPSCC were reviewed from 2016 to 2019. Opioid usage (standardized to morphine milligram equivalents [MME]) was gathered for 12 months post-surgery via prescribing record cross-check with the Massachusetts Prescription Awareness Tool.
Of 138 OPSCC TORS patients, 92.8% were human papillomavirus (HPV) positive. Adjuvant therapy included radiation (XRT;67.4%) and chemoradiation (cXRT;6.5%). Total MME usage from start of treatment averaged 1395.7 MMEs with 76.4% receiving three prescriptions or less. Categorical analysis showed age <65, male sex, overweight BMI, lower frailty, former smokers, HPV+, higher T stage, and BOT subsite to be associated with increased MMEs. Adjuvant therapy significantly increased MMEs (TORS+XRT1646.2; TORS+cXRT2385.0; TORS alone554.7 [P < .001]) and 12-month opioid prescription totals (TORS+XRT3.2; TORS+cXRT5.5; TORS alone1.6 [P < .001]). Adjuvant therapy increased time to taper (total MME in TORS alone versus TORS+XRT/cXRT 0 to 3 months428.2 versus 845.5, 4 to 6 months46.8 versus 541.8, 7 to 9 months12.4 versus 178.6, 10 to 12 months11.0 versus 4.4,[P < .001]). Positive predictors of opioid prescribing at the 4- to 6-month and 4- to 12-month intervals included adjuvant therapy (odds ratio [OR]5.56 and 4.51) and mFI-5 score ≥3 (OR36.67 and 31.94). Following TORS at 6-, 9-, and 12-month, 15.7%, 6.6%, and 4.1% were still using opioids.
In OPSCC treated with TORS, opioid use tapers faster for surgery alone versus with adjuvant therapy. Opioid prescribing risks include adjuvant therapy and higher frailty index.
4 Laryngoscope, 2020.
4 Laryngoscope, 2020.Thymol, a monoterpene phenol, is used as a natural biocide. To circumvent its chemical instability, we propose use of thymol-loaded biogenic silica nanoparticles (BSiO2 #THY NPs); however, the toxicity of this system for aquatic organisms is unknown. Thus, the present study aimed to evaluate the toxicogenetic effects induced by thymol, BSiO2 NP, and BSiO2 #THY on Artemia salina and zebrafish (Danio rerio) early life stages. We also investigated the impact of BSiO2 aggregation in different exposure media (saline and freshwater). Based on the median lethal concentration at 48 h (LC5048h ), BSiO2 #THY (LC5048h  = 1.06 mg/L) presented similar toxic potential as thymol (LC5048h  = 1.03 mg/L) for A. salina, showing that BSiO2 had no influence on BSiO2 #THY toxicity. Because BSiO2 aggregated and sedimented faster in A. salina aqueous medium than in the other medium, this NP had lower interaction with this microcrustacean. Thus, BSiO2 #THY toxicity for A. salina is probably due to the intrinsic toxicity of thymol. https://www.selleckchem.com/products/jdq443.html For zebrafish early life stages, BSiO2 #THY (LC5096h  = 13.13 mg/L) was more toxic than free thymol (LC5096h  = 25.60 mg/L); however, BSiO2 NP has no toxicity for zebrafish early life stages. The lower aggregation of BSiO2 in the freshwater medium compared to the saline medium may have enhanced thymol's availability for this aquatic organism. Also, BSiO2 #THY significantly induced sublethal effects as thymol, and both were genotoxic for zebrafish. In conclusion, although BSiO2 #THY still needs improvements to ensure its safety for freshwater ecosystems, BSiO2 NP seems to be a safe nanocarrier for agriculture.

To synthesize data on prevalence and risk factors for return to work (RTW) in ICU survivors.
Systematic review and meta-analysis.
PUBMED, CINAHL, EMBASE and PsycINFO databases were searched from 2000-Feb 2020.
Peer-reviewed articles that included adult ICU survivors and employment outcomes. Two investigators independently reviewed articles following the PRISMA protocol. Pooled prevalence for RTW was calculated. Meta-regression analyses were performed to assess the association between disability policies, temporal factors and RTW following ICU.
Twenty-eight studies (N=8,168) met the inclusion criteria. All studies were scored as 'low risk of bias'. Using meta-analysis, the proportion (95% CI) of RTW following ICU was 29% (0.20,0.42), 59% (0.50,0.70), 56% (0.50,0.62), 63% (0.54,0.72), 58% (0.37,0.91), 58% (0.42,0.81), and 44% (0.25,0.76) at 3, 4-6, 7-12, 13-24, 25-36, 37-48, and 49-60months, respectively. Time and disability policy support are factors associated with the proportion of ICU survivors who RTW.
