Previously reported maize, A. thaliana and O. sativa phosphate transporter proteins were used as queries against the maize genome database. After removal of overlapping sequences, the remaining genes were verified in the Pfam database (http://pfam.xfam.org/). The protein sequences were aligned by the ClustalX (Version 1.81) with default parameters. Then, the phylogenetic tree was constructed with the neighbor-joining method within MEGA 6, and the bootstrap was 1000 replicates in the mode of pairwise gap deletion [37 (link)]. The exon and intron structures of each ZmPHT1 gene were analyzed by GSDS (Gene Structure Display Server; http://gsds.cbi.pku.edu.cn/) through alignment of their CDS with corresponding genomic DNA sequences. Conserved motifs among the ZmPHT1 genes were examined via MEME software (Multiple Expectation Maximization for Motif Elicitation) [38 (link)], and the parameters were set as follows: the number of repetitions was choose any; the maximum number of motifs was 10; and the optimum motif width was set between 6 and 50 residues. Moreover, motif annotation was performed by the Pfam and SMART (http://smart.embl-heidelberg.de/) tools. Chromosome location was performed using the Map Inspect software [39 (link)]. The duplication pattern for each ZmPHT1 gene was analyzed by MCScanX software [40 (link)], and the synthesis map was drawn by Circos software (http://circos.ca/) [41 (link)]. Gene clusters that met the following specific clustering criteria were selected, i.e., genes arising from tandem duplication events on the same chromosome region, two or more homologous genes within a 200-kb region [42 (link)] and fragments derived from replication events [43 (link)]. The calculation of Ka, Ks was by DnaSPv5.0 [44 (link)]. The nonsynonymous substitution per synonymous site (Ka/Ks) ratio analysis was performed by sliding window analysis with the parameters as follows: window size, 150 bp; step size, 9 bp [42 (link)]. The gene expression data from Maize B73 transcriptomes were used to draw a heat map [28 (link)], including information from germinating seeds, primary roots, stems, SAMs (shoot apical meristem), leaves, endosperm, embryos and whole seeds. Promoters were analyzed by RSAT (http://floresta.eead.csic.es/rsat/) [45 (link)].

Based on our review of the SCD literature, considerations of relevance to the field, and feasibility, we investigate the following ten issues through descriptive and content analysis of SCD-I Working Group measures: (1) number of self-report measures used by participating working group studies; (2) origin of instruments and mode of administration; (3) format and range of response options; (4) timeframe referenced by the items; (5) prevalence of items related to specific cognitive domains; (6) prevalence of items tapping cognitive ability/disability-impairment (and referents of frequency, severity, and impact) versus change or decline (and referents of temporal and atemporal); (7) item specificity and complexity; (8) overlap in measures used by working groups; (9) most commonly occurring items; and (10) considerations driving measure selection and the grouping of questionnaires within a given study. Coding of cognitive self-report items occurred prior to data analysis for research issues 1, 5, 6, 7, 9, and 10. For all coding procedures, working group member LAR carried out the initial coding. Two additional expert raters (working group members CMS and SAMS) subsequently identified items that they considered to be miscoded. Items in dispute were then reviewed and discussed until consensus was reached, occasionally after discussing disputed items with working group member PKC.

For tBLMs completed with RSE, lipid mixtures of the desired bilayer composition were dissolved in organic solvents at a concentration of 2.5 mg/mL. Zwitterionic lipid mixtures were dissolved in ethanol, mixtures containing anionic lipids were dissolved in a mixture of 95 % methanol, 4 % chloroform, and 1 % water by volume. SAM/mixed SAM-coated wafers were exposed to the lipid solution for 5 min and thereafter the organic lipid solution rapidly replaced by buffer (RSE method). Buffers for tBLMs prepared with RSE contained 10 mM Na2HPO4 and 100 mM NaCl adjusted to pH 7.4 using diluted HCl solution.
For tBLMs completed with vesicle fusion, vesicles were prepared from 2.5 mg lipid-dried films of the desired lipid composition. Lipids were suspended in 1 mL of buffer and sonicated until the solution became clear. The vesicles were extruded at least 13 times using a manual extruder (Avanti Polar Lipids, Inc., Alabaster, AL) equipped with two 100 nm filters. For vesicle fusion, the vesicles were diluted to a final concentration of 1mg/ml and kept at room temperature. Silicon wafers coated with the mixed tether/βME SAMs were exposed to the vesicle solution for 1h and then rinsed with buffer. Buffers for the preparation and measurement of tBLMs completed by vesicle fusion were 50 mM K2HPO4 adjusted to pH 7.45 using HCl solution.

C57BL/6 mice were re-derived to germ-free status52 (link). Gnotobiotic C57BL/6 mice colonized with ASF or sDMDMm2 containing 12 defined bacterial strains (called the Oligo-Mouse-Microbiota, see ‘Bacterial strains') were generated and maintained at the clean mouse facility of the University of Bern. SPF mice (on a C57BL/6 background) were purchased from Harlan Laboratories. Monocolonization was performed by intragastric administration of 1010 colony-forming units (CFU; if not otherwise specified) of E. coli or B. thetaiotaomicron into 8- to 16-week-old mixed-sex germ-free mice. Bicolonization was established in 8- to 16-week-old mixed-sex germ-free mice by orally gavaging with 1010 CFU of E. coli and 1010 CFU of B. thetaiotaomicron. Mice were either used germ-free or stably colonized over 5 days with the organism(s) shown, except for trajectory experiments for bacterial replication where time points between 8 and 24 h were used. Control experiments confirmed that the dose of 1010 CFU was saturating and established a steady state at the outset, whereas doses ≤108 CFU required an initial phase of replication before the biomass reached steady state at 18 h. Germ-free mice were routinely monitored by culture-dependent (Luria-Bertani Broth (LB) agar and Wilkin's Anaerobic media (Oxoid) supplemented with 5% defibrinated sheep's blood) and culture-independent (Gram stain and cell-impermeant nucleic acid stain Sytox green) methods to confirm sterility. All mouse experiments were performed in accordance with the Swiss Federal and Cantonal regulations and were approved by the Ethics Committee for Animal Experimentation of the SAMS and SCNAT.

AMPK complexes were expressed in E. coli BL21 (DE3) cells, purified by affinity chromatography using nickel-Sepharose and phosphorylated by incubation with CaMKKβ as described previously9 (link). AMPK activity was determined using 0.2 mM SAMS peptide9 (link), 0.2 mM ATP and 5 mM MgCl2. Dephosphorylation of AMPK by recombinant PP2Cα was monitored either by measuring AMPK activity using the SAMS peptide assay or by Western blotting of phospho-T172. Western blot signals for phospho-T172 and total AMPK α subunit (determined using sheep anti-α1 or anti-α2 antibodies) were quantified using the Li-Cor Odyssey infrared imaging system. Uncorrected fluorescence spectra of the nucleotides (3′-(7-diethylaminocoumarin-3-carbonylamino)-3′-deoxy-ADP (C-ADP), and 3′-(7-diethylaminocoumarin-3 carbonylamino)-3′-deoxy-ATP (C-ATP) (both generous gifts from Dr. Martin Webb, MRC NIMR, London)) and NADH and their complexes were recorded at 20°C using a Jasco FP-6300 fluorimeter. Binding of nucleotides was monitored by titrating nucleotide (4-10 μM) with AMPK. Dissociation constants for AMP, ADP, and ATP were determined using competition assays. The engineered crystallization construct was expressed as a His-tag fusion protein in E. coli. Purified protein was phosphorylated using CAMKKβ before mixing with AMP and staurosporine. Crystals were grown by the hanging drop method using isopropanol and MPD as precipitant. Diffraction data were collected on the Diamond Light Source, Oxford and processed using Denzo and Scalepack28 . The structure was solved by molecular replacement using Amore29 and standard refinement was carried out with Refmac530 (link) with manual model building with COOT. Figures were created with Pymol (http://pymol.sourceforge.net/).

Microsurgical fellows were prospectively evaluated using the validated Structured Assessment of Microsurgical Skills (SAMS) tool by 24 attending plastic surgeons at the commencement and completion of the fellowship.9 Fellows underwent a condition-standardized clinical evaluation during free flap reconstruction and laboratory-based evaluation during rat femoral artery anastomoses. SAMS is composed of 12 components that are divided into four major categories of microsurgical skills: dexterity, spatial awareness, operative flow, and judgment. Higher scores indicate better performance. Scores are presented as initial (beginning of fellowship) or final (end of fellowship) scores, and clinical or laboratory. A comprehensive description of SAMS and its components can be found in the Supplemental Digital Content 1. (See appendix, Supplemental Digital Content 1, which displays the supplementary materials. http://links.lww.com/PRSGO/C429.)

We calculated pairwise FST using Weir and Cockerham’s estimator [32 (link)] over 1,000 bootstraps through the hierfstat package for R [33 ]. Due to the relative nature of FST estimates, we conducted a second analysis to compare our pairwise FST estimate to the pairwise values between other free-breeding dog populations. For this second analysis, we used open-source SNP data acquired and published by Pilot et al. ([34 (link), 35 ]; hereafter, Pilot et al. dataset) and used hierfstat to also calculate pairwise FST amongst free-breeding dog populations across Europe and Asia. Pilot et al. [34 (link)] genotyped 324 individuals with the CanineHD Whole-Genome Genotyping BeadChip (Illumina), so, to maintain consistency in our comparisons, we filtered each SNP dataset to retain only those SNPs included on both the Illumina and Affymetrix arrays and which were present in at least 50% of individuals in both datasets. This filtering resulted in 147,592 SNPs (147 K set). We recalculated pairwise FST for Chernobyl City and Nuclear Power Plant populations and then calculated pairwise FST for the free-breeding dog populations included in the Pilot et al. dataset, which included dogs sampled in Poland, Slovenia, Iraq, Saudi Arabia, Armenia, Central Russia, Eastern Russia, Kazakhstan, Tajikistan, China, Mongolia, and Thailand.
We used the hierfstat package to measure observed and expected heterozygosity for each locus, which we compared across populations with a paired t-test with the alpha corrected for multiple comparisons (corrected α = α / 301,023). We used the R package SNPRelate [36 (link)] to calculate individual inbreeding coefficients with Visscher’s estimator as described by Yang et al. [37 (link)] and compared measures between populations through Welch’s two sample t-test. As an additional measure of inbreeding, we analyzed runs of homozygosity (ROH) per individual with PLINK (–homozyg). For this, we utilized the 427 K Set for all 116 unique individuals, subset for each population, because minor allele frequency filtering can overlook homozygous stretches which limits ROH detection [38 (link)]. This also allowed for more comprehensive coverage for the scans. We selected parameters based on Sams and Boyko [39 (link)] and Morrill et al. [40 (link)] to best accommodate SNP coverage for our data set: ROH longer than 500 kb (–homozyg-kb 500), contained at least 50 SNPs (–homozyg-snp 50), and contained no heterozygous calls (–homozyg-window-het 0). Inverse density (Kb/SNP) and gap size thresholds were set high (–homozyg-density 5000, –homozyg-gap 1000) to ignore [39 (link)]. We then calculated each individual’s FROH, using the proportion of genome covered by ROH as a measure of inbreeding [38 (link)]. The FROH scores, averaged across populations, were compared using Welch’s Two Sample t-test.

For cleaning the bare Au(111) substrate prior to SAM deposition, the gold substrates were annealed in a furnace at 733 K for 4 h and immediately quenched in N2-bubbled ethanol (EtOH) solvent. MEHA SAMs were prepared by immersion of the Au(111) substrate in a 0.01 mM EtOH solution of MEHA for a desired period (1 min, 10 min, and 1 h) at RT. A schematic view of the formation of MEHA SAMs through hydrogen bonding networks can be seen in Figure 1. The resulting MEHA SAMs on Au(111) were removed from solution, immediately rinsed with pure EtOH solvent, and dried with an N2 stream. To compare the thermal stability of MEHA and DT on Au(111), pre-covered DT SAMs were also prepared after 1 h deposition in a 0.01 mM EtOH solution of DT. To compare the thermal stability of pre-covered MEHA and DT SAMs, both SAMs were annealed at 373 K for 1 h.

More about "Sams"

Sams, also known as freshwater perch or crappie, are a diverse group of small, tasty fish found throughout rivers and lakes in North America.
These members of the Percidae family are prized by anglers for their aggressive feeding behavior and strong fighting ability.
Sams typically range from 6-12 inches in length and prefer cool, clear waters, making them a valuable indicator species for monitoring the health of aquatic ecosystems.
In addition to their role as a popular gamefish, sams play a crucial part in freshwater food webs, serving as a food source for larger predatory fish as well as birds and other wildlife.
Their distinct coloration and flavorful flesh have also made them an economically significant component of many regional fisheries across the United States.
Beyond their ecological and economic importance, sams share similarities with other small freshwater fish like the [γ-32P]ATP-utilizing perch, which also exhibit aggressive feeding habits and function as indicator species.
Techniques like the TRIzol reagent and RNeasy Mini Kit can be leveraged to study the genetic and molecular characteristics of sams, while the LSM 780 confocal microscope and AFM Multimode MMAFM-2 atomic force microscope could provide insights into their anatomy and physiology.
The SAMS peptide, a synthetic analog of the ADP-Glo Kinase Assay substrate, may also hold relevance for understanding sams' metabolic processes and signaling pathways.
Ultimately, the versatile and valuable sams continue to captivate anglers, researchers, and conservationists alike, with their unique place in freshwater ecosystems and potential for further scientific exploration.
Whether you're casting a line or conducting laboratory analyses, these small but mighty fish remain an imporrtant focus of study and appreciation.
