description: ABSTRACT People form impressions of one another in a split second from faces: some look warm or competent, others untrustworthy or aggressive. However, people also infer others’ momentary mental states based on context. For instance, people would infer that somebody feels encouraged when receiving constructive feedback, or impatient when driving behind a slow driver. How do trait judgments of faces influence these context-based mental state inferences? We will ask participants to infer the mental states of unfamiliar people, identified by their neutral faces, under specific contexts. To increase generalizability, we representatively sample all stimuli from inclusive sets using computational methods. We test four hypotheses: that trait impressions of faces (1) are correlated with subsequent mental state inferences in a range of contexts, (2) alter the dimensional space that underlies mental state inferences, (3) are associated with specific mental state dimensions in this space, and (4) causally influence mental state inferences.

description: A series of new imidazolium salts (1–4) as N-heterocyclic carbene (NHC) precursors have been synthesized by successive N-alkylation method. Reactions of these salts with Ag2O by varying the metal to salt ratio forms a series of new Ag(I)–NHC complexes (5–8). All compounds were characterized by physico-chemical and spectroscopic techniques. The molecular structures of 1 and 5 were characterized by single-crystal X-ray diffraction analysis. A comparative investigation of the bacterial growth inhibition potential of the salts and respective complexes indicates that 5–8 displayed good antibacterial activities on Staphylococcus aureus (ATCC 12600) and Escherichia coli (ATCC 11303) compared with the salts. Furthermore, it was observed that with increase in chain length at N-positions, the antibacterial activities also increased. Nuclease activity of the reported salts and Ag(I)–NHC complexes with nucleic acids (DNA and RNA) were also studied using agarose gel electrophoresis; the results show that the compounds do not have any apparent interaction with nucleic acids in the absence of hydrogen peroxide (H2O2). However, 5 and 8 were efficient in promoting the cleavage of nucleic acids in the presence of H2O2.

description: Due to the limited thermal stability of current commercially available liquid crystals (LCs), the incorporation into polymer composites through standard processing techniques, such as melt coextrusion, has been hindered. Motivated by this dilemma, a series of smectic B liquid crystalline structures based on the 4,4ʹ-alkyl substituted biphenyl moiety were synthesised through conventional methodologies and probed for their thermal stability and LC properties. Degradation temperatures were found to increase with increasing aliphatic chain length – up to 295 °C for C16 substituted structures, which is well above the processing temperatures of commercial polymers. Additionally, all compounds were found to be liquid crystalline in nature with crystal-to-smectic B transition temperatures ranging from 49.8 °C to 91.4 °C. Thermal stability, phase separation, and compatibility of LC/polystyrene composites were also examined. Less than 10% of 15A15 LC by weight in polystyrene exhibited good polymer miscibility, while phase separation occurred at loads higher than 15% by weight. We foresee the use of these LCs in applications that require elevated processing conditions to produce materials with enhanced mechanical or gas barrier properties.

pup-care behavior

description: In many species, females show little to no interaction with pups as virgins but display an array of care behaviors towards pups when they become moms. Recent work from my mentor in the Luo lab, Alina Xiao, shows that serotonin (5-HT) is an important neuromodulator mediating such behavioral transition. While conditionally knocking out Tph2—a gene encoding for an enzyme required for 5-HT synthesis—in serotonin neurons that project to the medial preoptic area (mPOA) significantly suppresses pup interaction in moms, the same manipulation in serotonin neurons that project to the bed nucleus of the stria terminalis significantly increases pup interaction in virgins. However, because mPOA- and BNST-projecting serotonin neurons collateralize to other brain regions, it is unknown whether 5-HT activity is required at all axon collaterals or locally in mPOA or BNST to modulate pup interaction across reproductive stages. This current study thus investigates the local, short-term effects of disrupting 5-HT activity in mPOA or posterior BNST (BNSTpr) on pup interaction via serotonin receptor 2C antagonist (2C–) infusion. Consistent with the previous loss-of-function experiment, 2C– infusion in mPOA suppressed pup-interaction in moms but promoted pup-interaction in BNSTpr in virgins. However, unlike in the conditional knockout of Tph2, 2C– infusion in mPOA also significantly decreased pup interaction in virgins and disrupted pup retrieval in moms, demonstrating that an acute, local disruption of 5HT activity in mPOA disrupts pup interaction more severely than long-term, whole-cell deletion of serotonin synthesis. Together, findings from this current study support that 5HT activity in mPOA and BNSTpr is functionally heterogeneous and further highlight that 5HT is required locally in mPOA and BNSTpr to promote and suppress pup care behavior, respectively.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: We present gas and stellar kinematics of a high-resolution zoom-in cosmological chemodynamical simulation, which fortuitously captures the formation and evolution of a star-forming barred spiral galaxy, from redshift z similar to 3 to z similar to 2 at the peak of the cosmic star formation rate. The galaxy disc grows by accreting gas and substructures from the environment. The spiral pattern becomes fully organized when the gas settles from a thick (with vertical dispersion sigma(v) > 50kms(-1)) to a thin (sigma(v) similar to 25kms(-1)) disc component in less than 1Gyr. Our simulated disc galaxy also has a central X-shaped bar, the seed of which formed by the assembly of dense gas-rich clumps by z similar to 3. The star formation activity in the galaxy mainly happens in the bulge and in several clumps along the spiral arms at all redshifts, with the clumps increasing in number and size as the simulation approaches z= 2. We find that stellar populations with decreasing age are concentrated towards lower galactic latitudes, being more supported by rotation, and having also lower velocity dispersion; furthermore, the stellar populations on the thin disc are the youngest and have the highest average metallicities. The pattern of the spiral arms rotates like a solid body with a constant angular velocity as a function of radius, which is much lower than the angular velocity of the stars and gas on the thin disc; moreover, the angular velocity of the spiral arms steadily increases as a function of time, always keeping its radial profile constant. The origin of our spiral arms is also discussed.
Teacher educator perceptions of mathematical knowledge for teaching – A phenomenographic study

description: Teacher education is a complex policy and practice landscape and teacher educator roles are changing. This thesis investigates variation in how teacher educators in England account for their practices within initial teacher education, in the context of secondary mathematics. It sets out a view of their experiences of teacher education in relation to different ways of accounting for relations between knowledge about teaching and learning mathematics and knowledge of mathematics. Outcomes are based on interviews with sixteen participants, including both school-based and university-based teacher educators. Teacher educator accounts comprised four, hierarchically inclusive descriptions of learning in teacher education: (1) understanding teaching and learning in mathematics (2) linking teaching and learning with the subject discipline of mathematics (3) integrating teaching and learning with the subject discipline of mathematics (4) reconceptualisation of teaching and learning with mathematics. Accounts of teacher education are structured as expanding opportunities for student teachers to engage critically with the process of reconceptualising mathematical knowledge into ‘school maths’ knowledge. The most developed accounts position teacher education as drawing on opportunities for student teachers to experience interplay between mathematics and school mathematics through advanced and multiple mathematics perspectives. This interplay is a site of learning in teacher education. Participants hold a range of teacher educator roles, including school-based and university-based roles. Teacher educators in school-led roles were less able to draw on this interplay in practice and so this thesis is a further and timely contribution to the research about university-based teacher educators. This thesis contributes a curriculum forms perspective that focuses on teacher educator positions on the role of the curriculum in developing new teachers.

description: Background: Fibroblastic reaction can be observed in benign and malignant melanocytic lesions and cause serious diagnostic problems. The mechanism of fibrogenesis and the diagnostic utility of fibrogenesis markers have not been investigated in this context. Design: We analyzed symmetry, maturation, growth patterns (nested-trabecular, nodular-solid, diffuse), nuclear grade (including chromatin, nucleolus, pleomorphism and anisokaryosis), stromal reaction, and confluent necrosis in desmoplastic (sclerosing) melanocytic nevi (DMN, 18) and desmoplastic malignant melanoma (DMM, 24), classified according to the WHO criteria. Cases with history of previous excision, trauma or histological scarring were excluded. Representative samples were evaluated by quantitative RT-PCR and standard in situ techniques for morphogenesis and fibrogenesis pathways (fibrinogen, CD34, CTNNB1, FOXC2, JAG1, RAC1, SMAD2, SNAI1, SOX10, TGFB1, TGFB2, TGFB3, TWIST1, WNT11, WNT5A, PDGFA, SPARC, PDGFRA, HSPG2). Appropriate controls were run. Fisher’s exact tests and analysis of variance (significant if P<0.05) were used for comparison; significant variables were then selected for discriminant analysis with cross-validation for diagnostic groups (DMN vs. DMM). Results: Fibrinogen expression was found in both DMN and DMM but with different pattern: perivascular stroma in DMN and in tumour cells and blood vessels with a heterogeneous pattern in MM. CD34 was revealed positive in dermal dendritic cells of the sclerosed interstitium of DMN, and in the peritumoural stroma of DMM. PDGFRA was expressed in DMN, but not in DMM and HSPG2 (perlecan protein) revealed significantly higher expression in DMM. The remaining markers revealed no statistically significant differences in the expression by DMN and DMM. Conclusions: The sclerosis seen in DMN is directly correlated with fibrinogen leaking from blood vessels and it is not a destructive process (preserved intratumour CD34 positive cells), whereas the fibrogenesis in MM is secondary to tissue destruction (loss of intratumour CD34 positive cells and increased turnover of HSPG2) and is enhanced by PDGFRA-independent tumour cell expression of fibrinogen.

Improving deconvolution accuracy with cell size rescaling for heterogeneous tissues

description: Contributed paper presentation, delivered for Session 41, Next Generation Sequencing, at the Eastern North American Region Spring Meeting 2024, in Baltimore, MD, USA.

Abstract:

Estimating relative fractions of cell composition from bulk transcriptomics data is useful for differential expression analyses and for cell composition comparisons across conditions. While many deconvolution algorithms are published each year, not enough attention is given to cell size scale factor normalizations and resources are lacking to enable these normalizations in deconvolution across tissues and conditions. Normalizations on cell size help accurately quantify cell type proportions rather than total RNA content. To address this, we use the lute R/Bioconductor package for cell size scale factor normalization. Using a multi-omics dataset including single-nucleus RNA-seq, multi-condition bulk RNA-seq, and fluorescent label imaging in human dorsolateral prefrontal cortex, cell type proportion accuracy improved in systematic simulations and integrative analyses using size normalization. lute can be used to perform normalization in other regions of human prefrontal cortex to better determine relative roles of cell type-specific expression and their subsequent dysregulation in debilitating brain disorders. We propose to speak at ENAR 2024 about this work.

description: The antiradical activity of the freshwater bryozoan Hyalinella punctata water extracts (two samples, seasonal collection) was evaluated by using electron paramagnetic resonance spectroscopy against hydroxyl (√OH), superoxide anion (√O2− ), methoxy (√CH2OH), carbon-dioxide anion (√CO2− ), nitric-oxide (√NO) and 2,2-diphenyl-1-picrylhydrazyl (√DPPH) radicals. The extracts reduced the production of all tested radicals but to a varying degree. The better activity was observed against √CO2−  and √CH2OH radicals (54 ± 5% and 44 ± 4%, and 58 ± 6% and 22 ± 2%, respectively) than towards √DPPH, √NO, √OH and √O2−  radicals (59 ± 6% and 1.0 ± 0.1%, 46 ± 5% and 14 ± 1%, 7.0 ± 0.5% and 34 ± 3%, and 33 ± 3% and 0%, respectively). FTIR spectra of the both extracts indicate the presence of cyclic peptides and polypeptides which might be responsible for the observed activity. According to the experimental data obtained, H. punctata water extract may be considered as a novel promising resource of natural products with anti √CO2−  radical activity.

description: The activities of ornithine transcarbamoylase (OTC) and arginase enzymes in Chenin blanc berries from potted vines irrigated with four different levels of nitrogen (0, 2, 4 and 8 mM NO3-) were determined periodically through the period of fruit ripening. OTC activity was maximal at veraison, declined rapidly thereafter with a second smaller peak of activity at fruit maturity. Arginase also generally showed maximal activity at veraison and then decreased gradually until fruit maturity, except for 8 mM N03- fruit, which showed increasing arginase activities during the last 5 weeks of fruit ripening. Activities of both OTC and arginase generally increased with increasing level of nitrogen fertilization. Berry weight increased up to 4 mM NO3 - ; however, nitrogen had no consistent influence on the level of total soluble solids in fruits. Der Einfluß der Stickstoffdüngung auf die Aktivität der Ornithintranscarbamylase und der Arginase in den Beeren der Rebsorte Chenin blanc während verschiedener Stadien ihrer Entwicklung Topfreben von Chenin blanc wurden mit vier Stickstoffkonzentrationen (0, 2, 4 und 8 mM NO3 -) gedüngt; im Verlauf der Beerenentwicklung wurde in regelmäßigen Abständen die Aktivität der Ornithintranscarbamylase (OTC) und der Arginase in den Beeren bestimmt. Die OTC-Aktivität war am höchsten während des Weichwerdens der Beeren, nahm danach rasch ab und zeigte ein zweites kleineres Maximum zur Zeit der Beerenreife. Auch die Arginase wies im allgemeinen ihre höchste Aktivität während des Weichwerdens auf und nahm dann gegen die Beerenreife allmählich ab; eine Ausnahme bildete die Variante mit 8 mM N03-, die einen Anstieg der Arginaseaktivität in den letzten 5 Wochen der Beerenreife zeigte. Mit ansteigenden Stickstoffgaben nahm die Aktivität sowohl von OTC als auch von Arginase im allgemeinen zu. Das Beerengewicht stieg bis zu 4 mM NO3 - an; auf die Höhe des Mostgewichtes hatte die Stickstoffversorgung jedoch keinen erkennbaren Einfluß.

description: Eleven compounds, including four flavonoids [(2R,3R)-2,3-dihydro-3,5-dihydroxy-7,4′-dimethoxyflavone (1), 5-hydroxy-7,8,4′-trimethoxy-flavone (2), amentoflavone (10) and apigenin (11)], two penylpropanoids [sinapaldehyde (3) and 3-methoxy-4-hydroxy-cinnamic aldehyde (4)], three phenolic acids [4-hydroxyl-3,5-dimethoxy-benzaldehyde (5), 4-hydroxyacetophen-one (6) and p-hydroxybenzaldehyde (7)], one furan derivative [5-hydroxymethyl furfural (8)] and one steroid saponin [β-sitosterol-3-O-β-d-glucoside (9)], were isolated and identified from Aletris spicata. Among them, compounds 1–7, 9 and 10 were reported from the genus Aletris for the first time. Furthermore, seven of them (1–6, 10) were obtained from the family Liliaceae for the first time. Chemotaxonomy of the isolated compounds is discussed briefly.

description: We have confirmed the findings of LANGCAKB and PRYCE and extended them to include species which have significant resistance to disease. Using these species we have observed differential production of resveratrol both within and among clones in relation to the incidence of disease. The techniques we have used fit the requirements of a screening technique. Unlike the analytic technique most recently used by LANGCAKE and McCARTHY (6) resveratrol and the viniferins are separated in our procedures. Minimal amounts of tissue are required, and TLC combined with either UV or fluorescence spectrophotometry give rapid quantitative results. The use of UV to induce the production of these "stress metabolites" would free the breeder from the necessity of maintaining fungus cultures for inoculation tests. Further study must be done to elaborate the role of these compounds in disease resistance and the efficacy of their role in predicting resistance. Resveratrol und die Viniferine - ihre Verwendbarkeit bei der Bonitierung der Pilzresistenz im Rahmen von Rebenzüchtungsprogrammen Die Ergebnisse von LANGCAKE und PRICE bezüglich der Phytoalexinbildung bei Reben wurden bestätigt; entsprechende Befunde ließen sich auch bei einer Ausdehnung der Untersuchungen auf Rebenarten, die eine hohe Pilzresistenz besitzen, aufzeigen. Bei diesen Species wurde sowohl innerhalb der Klone wie auch zwischen den Klonen eine abgestufte Resveratrolbildung beobachtet, die in Beziehung zum Auftreten von Pilzkrankheiten stand. Die angewandte Technik erfüllt die Anforderungen, die an eine Bonitierungsmethode zu stellen sind. Resveratrol und die Viniferine konnten nunmehr gesondert bestimmt werden. Hierzu sind nur geringe Mengen von Rebenmaterial erforderlich, und mittels Dünnschichtchromatographie in Verbindung mit UV- oder Fluoreszenzspektrophotometrie lassen sich rasch quantitative Ergebnisse erzielen. Die Verwendung von UV-Licht zur Induktion der „Streßmetabolite" würde den Züchter der Notwendigkeit entheben, Pilzkulturen für Inokulationstests zu halten. Zum besseren Verständnis der Rolle, die diese Verbindungen bei der Pilzresistenz spielen, sind ebenso wie bezüglich ihrer Verwendung zur Resistenzvorhersage weitere Untersuchungen erforderlich.

description: Minimum inhibitory concentration (MIC) and IC50 values and total phenolics of dog rose fruits were 72.5–80 μL mL− 1, 130 μg mL− 1 and 5.7 mg GA g− 1, respectively. The Fashand watercress population and dog rose extracts exhibited mycelia growth inhibition values of 45.08% and 37.12%, respectively. The results of in vivo study indicated that the treatment of inoculated fruits with both methanol extracts especially the watercress plant extract considerably controls the citrus fruits decay (Penicillium digitatum) up to 73%. In conclusion, methanol extracts of dog rose fruits and especially watercress plant had the potential to be used against citrus green mould and even for the improvement of postharvest quality of orange fruits.

description: An 1jährigen Rebstecklingen (Vitis rupestris 187 G.) in Hydroponikkultur, die sowohl ober- wie unterirdisch von der Reblaus befallen oder nur an Blättern bzw. Wurzeln vergallt oder gänzlich reblausfrei waren, wurde mit Hilfe von 14C02 der Einfluß der Reblausvergallung auf die Bildung und Verteilung von Assimilaten untersucht. Blattvergallung hatte stets eine Retention radioaktiv markierter Verbindungen im Blattbereich und einen verminderten Export von Assimilaten nach dem Wurzelbereich zur Folge. Wurzelvergallung war ebenfalls mit einer Anreicherung von 14Cin den Nodositäten verbunden, die jedoch nicht das Ausmaß der für die Blattgallen geschätzten Werte erreichte und zu einer Verarmung der normalen Wurzelpartien an radioaktiven Substanzen führte. Die von einer Rebe durchschnittlich inkorporierte Gesamtmenge an 14C unterschied sich zwischen den einzelnen Versuchsvarianten nicht oder nicht einschneidend. Die gesteigerte Akkumulation von Assimilaten in den - photosynthetisch nur schwach aktiven - Blattgallen läßt auf eine Intensivierung der Photosyntheseleistung in den normalen Bezirken der verganten Blätter schließen. Die Bedeutung der ReblausvergaHung für das Verteilungsmuster der Assimilate wird unter dem Aspekt von Source-Sink-Beziehungen diskutiert. The effects of phylloxera leaf and root galls on the pattern of assimilate distribution in grapevine (Dactylosphaera vitifolii Shimer on Vitis rupestris 187 G.) Young grapevine cuttings growing in hydroponic culture and galled by phylloxera on both leaves and roots, on leaves only, on roots only, or not infested at all were exposed to 14C02 for 1 h and the distribution of radioactivity incorporated into the various plant parts 24 h after the beginning of photosynthesis was studied. Galling of leaves always resulted in a retention of labelled substances in the leaves and a reduced export of assimilates to the roots. 14C was also accumulated in the root galls, its level, however, being lower than that estimated for the leaf galls. Root galling was accompanied by a decrease of labelled compounds in the unchanged parts of the roots. The mean total amount of 14C incorporated by a grapevine plant was similar in the four experimental groups. lt is concluded that the rise of radioactivity in the leaf galls which, according to former experiments, show only weak photosynthesis is due to an increase of photosynthesis in the normal leaf parts. The effects of phylloxera galls on the pattern of assimilate distribution were discussed in terms of source-to-sink relationships.

description: An electrochemical method was developed for the determination of mercury using polycrystalline gold electrode modified by self-assembled monolayers (SAMs) of 2-mercaptobenzothiazole (MBTH). Morphological and electrochemical characterisation of the self-assembled structure of MBTH was performed using atomic force microscopy (AFM) and electrochemical impedance spectroscopy (EIS) measurements. The monolayer of MBTH has shown high affinity for Hg2+. The limit of detection for the determination of Hg2+ using the MBTH SAMs modified gold electrode was obtained as 0.421 μg L−1. The pre-concentration of Hg2+ at open circuit potential is beneficial for the onsite monitoring of mercury concentration in water samples.

description: Optimization of the M9 medium for production of Penicillin G Acylase (PGA) from recombinant E. coli DH5α carrying a plasmid encoding pac from Bacillus badius was carried out based on response surface methodology (RSM). For the first time M9 medium was used for enhancing the production of PGA from recombinant B. badius pac expressed in E. coli DH5α. RSM is a useful method for studying the effect of several variables influencing the responses by varying them simultaneously and carrying out a limited number of experiments. The initial screening method of Plackett-Burman design gave rise to identification of fructose, yeast extract, and magnesium sulfate as significant medium components. A 23 full-factorial central composite design (CCD) was applied to further optimize concentration of each significant variable. The optimal concentration for production of PGA consisted of 10 g/l fructose, 6 g/l yeast extract, 1.85 ml/l MgSO4 · 7H2O (100 mM), 9 g/l disodium hydrogen phosphate, 4 g/l potassium dihydrogen phosphate, 0.75 g/l sodium chloride, 2 ml/l thiamine HCl (100 mM), and 2 ml/l calcium chloride (10 mM). The model prediction of PGA activity (14.11 U/ml) at optimum conditions was verified experimentally (13.94 U/ml). Through statistically designed optimization, the production of PGA was found to go up from 2.2 U/ml to an average of 13.94 ± 0.03 U/ml. Thus the modified M9 media has shown a 7.74-fold increase in PGA activity.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.
