Abstract Charge Coupled Devices (CCD) are being used for reactor neutrino experiments and have already demonstrated their potential in constraining new physics models. The prospect of a Skipper-CCD experiment looking for standard and beyond standard model (BSM) physics in a nuclear reactor has been evaluated for different benchmark scenarios. Here, we report the first installation of a 2-g Skipper-CCD inside the containment building of a 2 GW th nuclear power plant and analyze its performance throughout its first 18 months of operation. The sensor was successfully deployed at Atucha II, in Argentina, 12 meters away from the center of the reactor core. We discuss the challenges involved in the commissioning of the detector and present data acquired during reactor ON and reactor OFF periods, with the sensor functioning with a sub-electron readout noise of 0.17 e−. Based on an exposure of 56.8 g day reactor ON and two reactor OFF data sets with a total exposure of 118.1 g day we characterize the system and evaluate the sensitivity to CEvNS. We achieved a background rate of 33 kdru and a low threshold of 45 eV ee . The ongoing efforts to improve sensitivities to CEvNS and BSM interaction are also discussed.

Abstract The cultivation of grapevines has spanned millennia, leading to thousands of varieties through exchanges, mutations, and crosses between genotypes, as well probably as gene flow from wild populations. These varieties are typically categorized by regional origin and primary use, either for wine production or fruit consumption. France, within the Western European group, hosts many of the world’s renowned wine grape varieties. However, the historical development of cultivated grapevines in France and in the world remains poorly understood. This study applies morphometry on 19,377 charred and waterlogged archaeological grape pips to investigate the evolutionary history of grapevine in France over the last 10,000 years. The study compares seed outlines and lengths, corrected for taphonomic distortions, with a reference collection of 80 wild and 466 modern domestic grapevine accessions. Findings reveal a shift from wild grapevine exploitation to the expansion of domestic varieties around 600–500 BCE, coinciding with Mediterranean cultural influences and the introduction of eastern grape types. The identification of the East-Table group, a group of varieties of eastern origin for fruit consumption, indicates that grapes were also grown for food, especially in Mediterranean regions and near urban areas, alongside wine production. Early French viticulture featured a notable presence of Western European wine-type grapevines. The abundance of pips with wild-like morphology suggests early cultivation involved plants at an initial domestication stage and gene flow between introduced and wild grapevines. As viticulture spread northward, wild and Eastern morphotypes declined, leading to the dominance of Western European wine types in inner France during the Middle Ages.

Abstract COSINUS is a dark matter (DM) direct search experiment that uses sodium iodide (NaI) crystals as cryogenic calorimeters. Thanks to the low nuclear recoil energy threshold and event-by-event discrimination capability, COSINUS will address the long-standing DM claim made by the DAMA/LIBRA collaboration. The experiment is currently under construction at the Laboratori Nazionali del Gran Sasso, Italy, and employs a large cylindrical water tank as a passive shield to meet the required background rate. However, muon-induced neutrons can mimic a DM signal therefore requiring an active veto system, which is achieved by instrumenting the water tank with an array of photomultiplier tubes (PMTs). This study optimizes the number, arrangement, and trigger conditions of the PMTs as well as the size of an optically invisible region. The objective was to maximize the muon veto efficiency while minimizing the accidental trigger rate due to the ambient and instrumental background. The final configuration predicts a veto efficiency of 99.63 ± 0.16% and 44.4 ± 5.6% in the tagging of muon events and showers of secondary particles, respectively. The active veto will reduce the cosmogenic neutron background rate to 0.11 ± 0.02 cts $$\cdot $$ · kg $$^{-1}\cdot $$ - 1 · year $$^{-1},$$ - 1 , corresponding to less than one background event in the region of interest for the whole COSINUS-1 $$\pi $$ π exposure of 1000 kg $$\cdot $$ · days.

Psychiatry ,RC435-571 - Abstract
Introduction The Positive and Negative Syndrome Scale (PANSS) has been used as a universal instrument for clinical assessment of psychopathology in schizophrenia. Different studies have analyzed the factorial structure of this scale and have suggested a five-factor model: positive, negative, excited, depressive, and cognitive/disorganized factors. Two of the most used models are the Marder´s solution and the Wallwork´s one. Objectives The aim of this work was to study the correlations of the two cognitive factors (Marder and Wallwork) with a cognitive assessment performed with a standard cognitive battery, in a sample of patients with first psychotic episode of schizophrenia. Methods Seventy four patients with first psychotic episode of schizophrenia (26.9, SD:7.8 years old; 70.3% male) were included. The cognitive assessment was performed with the MATRICS Consensus Cognitive Battery (MCCB). The MCCB present seven cognitive domains: Speed of processing, Working memory, Attention/Vigilance, Verbal Learning, Visual Learning, Reasoning and Problem Solving, and Social cognition). Pearson correlations were performed between MCCB scores and Marder´s PANSS cognitive factor (P2, N5, G5, G10, G11, G13, G15) and Wallwork´s one (P2, N5, G11). Results Correlation between MCCB scores and cognitive factors of Marder and Wallwork can be seen in the table. Marder´s cognitive factor Wallwork´s cognitive factor Speed of processing r = -0.461; p

Multi-objective optimization-based model calibration can be an intermediate solution between the computationally expensive probabilistic approaches and the single-objective optimization strategies that do not allow uncertainty quantification of the obtained solutions. This work addresses the multi-objective model calibration of two historic stone arch bridges using high-fidelity computational FE models. To implement the methodology, a five-step approach is proposed: experimental characterization through non-destructive testing techniques, non-parametric as-built geometric modeling, macro-finite element modeling, sensitivity analysis, and multi-objective optimization. The preferred solution among the Pareto front solutions is selected based on two different classical criteria, and the set of optimal solutions is further statistically analyzed to assess the validity of the identification process. The results show an average frequency error of 0.97 % and 0.70 % and an average MAC of 0.97 and 0.96 for each case study, respectively, thus highlighting the adequacy of the proposed methodology.

Hand metastasis represents between 0.007 and 0.2 % of all metastatic lesions [1, 2]. Renal cell carcinoma accounts for only 10–12 % [3, 4] of these infrequent lesions. Finger metastases are commonly misdiagnosed due to their low frequency and because they can resemble an infectious condition [5]. We report a case of renal clear cell carcinoma with distal phalangeal metastasis and review the related literature. This case highlights the need to consider acrometastasis in the differential diagnosis of digital lesions in patients with renal clear cell carcinoma. Case Report A 53-year-old right-handed man was seen by his family physician for pain and swelling in right fifth finger after a minor trauma; he had a history of disseminated renal clear cell carcinoma (RCC) with radiation-resistant metastases in lung and fourth lumbar and was under combined treatment with sunitinib and everolimus. The initial diagnosis was an infection, which was unsuccessfully treated with NSAIDs, cloxacillin and topic antiseptics, observing a continued increase in the swelling and the development of ulcers and necrotic areas (Fig. 1). Fig. 1 Clinical appearance of distal phalangeal metastasis of renal clear cell carcinoma. Swollen fifth finger with necrotic and fibrinous areas resembling an infectious process Plain radiographs of the right hand revealed a permeative osteolytic lesion in the distal phalanx of the right hand fifth finger with an ill-defined radiolucent mass. The cortex was thinned out and destroyed in places, but the adjacent joint surface was uninvolved and the remaining bones were unremarkable (Fig. 2). Serum levels of rheumatoid factor, uric acid, calcium, phosphate, and alkaline phosphatase were within normal limits, and puncture-aspiration samples were cultured without bacterial growth. Fig. 2 Plain radiographs confirm the presence of an expansile, lytic lesion at the distal phalanx of the right fifth finger with diffuse cortical break. The radiologic appearance is consistent with metastasis or infection Six weeks after the initial local symptoms, the patient was referred to our hand surgery unit for assessment. Metastatic involvement was strongly suspected and, because the finger was not viable, it was amputated through the proximal phalanx without previous biopsy. Specimen samples were sent for microbiologic and pathologic studies. The bacterial cultures were negative. Histopathological study revealed metastasis of renal clear cell carcinoma that caused distal phalanx destruction and partial skin ulceration. The features of the acrometastasis were similar to those of the primary tumor diagnosed 5 years earlier. The lesion was composed of multiple nodules of cells with clear cytoplasm, moderate nuclear atypia, poor vascular proliferation, and scant mitosis (2/10 high power fields). Surgical margins were negative (Fig. 3). Fig. 3 Cross-section of proximal phalanx with metastasis of renal clear cell carcinoma causing proximal phalanx destruction and partial skin ulceration (a). Panoramic image of histological section of the lesion stained with hematoxylin and eosin (H and E) ( ... There was a good recovery from the amputation, with an improvement in the hand pain. However, new lesions were observed on the third right hand finger tip, facial skin, and lips within a few weeks post-surgery, and the patient died after 3 months due to respiratory failure related to metastatic lung disease.

Hemp (Cannabis sativa L.), a difficult to transform plant, has been effectively infected with either Ri or Ti plasmid-bearing agrobacteria and several transformed tissues (tumors and hairy roots) were established and its transgenic nature confirmed. Hypocotyl of intact seedlings was the most responsive material and the response depended on both bacterial strain and plant variety. Transformed tissues were cultured and stabilized in vitro and showed the characteristic traits of fast and phytohormone-independent growth as well as high incidence of lateral branching and abundance of root hairs in the case of roots. The presence of some nitrogen compounds, metabolites of pharmaceutical implication, has been assayed in these transformed roots. Atropine, choline and muscarine were detected at quantitative levels in transformed roots and untransformed plant material of C. sativa. Further, the three compounds are present in hairy roots at concentrations quantitatively higher than in untransformed control tissues. Finally, hemp transformed roots exhibited a high callusing response, with calli that grew vigorously and developed compact and green nodular areas on the surface, a priori indicative of organogenesis capacity, but that were unable of shoot regeneration.

We review mammalian maternal behavior, its hormonal regulation, and the neurobiology involved in the onset and offset of specific behavioral patterns. We introduce topics that have flourished recently, e.g., the impact of maternal behavior on the maternal brain. We discuss neuroanatomical changes occurring in the ‘experienced’ mother's brain that translate into more efficient behavior and may underlie enhanced cognition and reduced fear and anxiety. We draw attention to little-explored topics, e.g., timing and the use of maternal behavior as an animal model for exploring specific aspects of neuropsychiatric disorders such as the exaggerated expression of stereotyped motor patterns.

Experimental conditions were optimized for hemp, a difficult to transform plant, to be effectively infected with either Ri or Ti plasmid-bearing agrobacteria and to establish stably transformed tissues. Hypocotyl of intact seedlings was the most responsive material and the response depended on both bacterial strain and plant variety. Transformed tissues, hairy roots and tumors, were cultured and stabilized in vitro and showed the characteristic traits of fast and phytohormone-independent growth as well as high incidence of lateral branching and abundance of root hairs in the case of roots. They all contained T-DNA of the corresponding Ri or Ti plasmid as revealed by PCR analysis with specific primers and further hairy roots induced by AR10GUS strain showed normal pattern of β-glucuronidase positive staining. To our knowledge, this represents the first reported protocol for the establishment of Cannabis sativa hairy root cultures.

Geodiversity is recognized as one of the most important drivers of ecosystem characteristics and biodiversity globally. However, in the northern Neotropics, the contribution of highly diverse landscapes, environmental conditions, and geological history in structuring large-scale patterns of aquatic environments and aquatic species associations remains poorly understood. We evaluated the relationships among geodiversity, limnological conditions, and freshwater ostracodes from southern Mexico to Nicaragua. A cluster analysis (CA), based on geological, geochemical, mineralogical, and water-column physical and chemical characteristics of 76 aquatic ecosystems (karst, volcanic, tectonic) revealed two main limnological regions: (1) karst plateaus of the Yucatán Peninsula and northern Guatemala, and (2) volcanic terrains of the Guatemalan highlands, mid-elevation sites in El Salvador and Honduras, and the Nicaraguan lowlands. In addition, seven subregions were recognized, demonstrating a high heterogeneity of aquatic environments. Principal component analysis (PCA) identified water chemistry (ionic composition) and mineralogy as most influential for aquatic ecosystem classification. Multi-parametric analyses, based on biological data, revealed that ostracode species associations represent disjunct faunas. Five species associations, distributed according to limnological regions, were recognized. Structural equation modeling (SEM) revealed that geodiversity explains limnological patterns of the study area. Limnology further explained species composition, but not species richness. The influence of conductivity and elevation were individually evaluated in SEM and were statistically significant for ostracode species composition, though not for species richness. We conclude that geodiversity has a central influence on the limnological conditions of aquatic systems, which in turn influence ostracode species composition in lakes of the northern Neotropical region.

Nowadays, several historical masonry arch bridges present a deficient state of conservation due to degradation processes induced by natural or human actions. Usually, these constructions have significant economic, cultural, and heritage value. Therefore, they shall be thoroughly assessed to verify their structural integrity and safety condition. For this purpose, reliability-based structural assessments are typically performed. However, the associated outcomes (i.e., reliability index and probability of failure) highly rely on the accuracy of the structural parameters uncertainty quantification. This work presents a study regarding the influence of the scattering of the arches' thickness dimensions in the load-carrying capacity assessment of the Cernadela Bridge, a historical stone bridge located in Galicia, Spain. The study first involved a comprehensive experimental campaign to characterize the outer and inner bridge geometry through geomatic techniques, i.e., terrestrial laser scanning and ground penetrating radar. Subsequently, a limit analysis model was developed, considering only the arches' outer (visible) data. From this initial structural assessment, a reliability index of 2.38 was obtained. The influence of the uncertain structural parameters, both geometric features and material properties, in the collapse load was investigated through a global variance-based sensitivity analysis (i.e., Sobol' indices) complemented by a surrogate modeling strategy based on the Kriging approach. Finally, the measured inner geometry of the arches was introduced in the computational model through Bayesian inference procedures. Thus, two new structural assessments were performed: first, by considering the updated distributions of all arches thicknesses, and second, by considering only the updated distributions of the non-influential ones. Reliability indexes of 1.51 and 2.33 were derived, thus highlighting the importance of a proper uncertainty quantification process and the relevance of the sensitivity analysis outcomes to identify the critical parameters on the bridge mechanical response.

La osteoporosis (OP) es una enfermedad muy prevalente, cuya consecuencia final, las fracturas, supone un importante deterioro en la calidad de vida de las personas que las sufren. Conocemos ampliamente que afecta mayoritariamente a la mujer, aunque no por eso debemos olvidar que la osteoporosis tambien afecta a los hombres. En el varon se retrasa la aparicion de fractura de cadera unos 10 anos con respecto a la mujer, pero su mortalidad es mayor. A los 60 anos el 25% de los hombres sufrira una fractura osteoporotica y a los 90 el 16,6% sufrira una fractura de cadera. La mayoria de los casos de OP diagnosticados en el varon son de causa secundaria (40-60%), los mas frecuentes son debidos a hipogonadismo y a excesiva ingesta de alcohol de forma cronica, pero tambien a la ingesta de glucocorticoides, la baja ingesta de calcio o la escasa actividad fisica. En este articulo resumimos las causas mas frecuentes de OP en el varon, la forma de evaluar a estos pacientes, las pruebas diagnosticas necesarias para su estudio y los diferentes tratamientos que podemos utilizar realizando para todo ello un enfoque desde Atencion Primaria.

The aim of this study was to find the structural changes in the rat testis after a diazinon administration. The testis structure changes after the diazinon administration of 20 mg/kg b.w. (i.p.) and daily dose of 40 mg/l in drinking water (p.o.) were evaluated in light microscopy. 36 hours after the diazion i.p. administration, the vacuolization of the seminiferous epithelium, evacuation of germ cells into the tubule lumen, epithelium necrosis and interstitium extension were observed. After 90 days of daily oral administration, the changes in the testis were not as visible as in the acute intoxication. The germ cells released from the basal lamina and then were visible in the tubule lumen. Diazinon causes the damage of the germinal epithelium in the testes leading to the spermatogenesis failure. The infertility can then appear.

IntroductionUrachal cancer (UrC) is a rare, non-urothelial malignancy. Its natural history and management are poorly understood. Although localized to the bladder dome, the most common histological subtype of UrC is adenocarcinoma. UrC develops from an embryonic remnant, and is frequently diagnosed in advanced stage with poor prognosis. The treatment is not standardized, and based only on case reports and small series. This large retrospective multicentric study was conducted by the French Genito-Urinary Tumor Group to gain a better understanding of UrC.Material and Methodsdata has been collected retrospectively on 97 patients treated at 22 French Cancer Centers between 1996 and 2020.ResultsThe median follow-up was 59 months (range 44-96). The median age at diagnosis was 53 years (range 20-86), 45% were females and 23% had tobacco exposure. For patients with localized disease (Mayo I-II, n=46) and with lymph-node invasion (Mayo III, n=13) median progression-free-survival (mPFS) was 31 months (95% CI: 20-67) and 7 months (95% CI: 6-not reached (NR)), and median overall survival (mOS) was 73 months (95% CI: 57-NR) and 22 months (95% CI: 21-NR) respectively. For 45 patients with Mayo I-III had secondary metastatic progression, and 20 patients were metastatic at diagnosis. Metastatic localization was peritoneal for 54% of patients. Most patients with localized tumor were treated with partial cystectomy, with mPFS of 20 months (95% CI: 14-49), and only 12 patients received adjuvant therapy. Metastatic patients (Mayo IV) had a mOS of 23 months (95% CI: 19-33) and 69% received a platin-fluorouracil combination treatment.ConclusionUrC is a rare tumor of the bladder where patients are younger with a higher number of females, and a lower tobacco exposure than in standard urothelial carcinoma. For localized tumor, partial cystectomy is recommended. The mOS and mPFS were low, notably for patients with lymph node invasion. For metastatic patients the prognosis is poor and standard therapy is not well-defined. Further clinical and biological knowledge are needed.

A probability distribution function F is said to be symmetric when 1 - F(x) - F(-x) = 0 for all x E R. Given a sequence of alternatives contiguous to a certain symmetric Fo, the authors are concerned with testing for the null hypothesis of symmetry. The proposed tests are consistent against any nonsymmetric alternative, and their power with respect to the given sequence can easily be optimized. The tests are constructed by means of transformed empirical processes with an adequate selection of the underlying isometry, and the optimum power is obtained by suitably choosing the score functions. The test statistics are very easy to compute and their asymptotic distributions are simple.

We previously found that the ethylene inhibitor Ag+ could overcome the inhibitory effect of nitrate on nodulation of soybean (Glycine max) cv. Bragg. The same treatment increased nodulation quantitatively under non-inhibitory conditions, strongly suggesting involvement of ethylene in the control of nodulation in this species. Supernodulation mutants that lack internal autoregulation of nodulation, however, had biosynthesis capacity similar to the wild type. In the present work, the effects of ethylene on nodulation of ‘Bragg’ and two separate, but allelic, supernodulating mutants (nts382 and nts1007) were compared. The nodulation process appeared much more sensitive than plant growth and development to ethylene, which reduced the number of nodules per plant, but nearly twofold more in the wild type than in the supernodulation mutants. The cause–effect relationship is established by the counteracting effect of Ag+ and the fact that the stronger the inhibition by ethylene, the higher the recovery of nodulation ability with the ethylene antagonist. This higher tolerance of or lower sensitivity to ethylene in nts382 persists even under low inoculum dose, where nodule number and mass could be decreased to wild-type levels. Differences between the mutant and the wild type in the triple response test do not appear to support differences in ethylene perception on a whole-plant basis. The results suggest that sensitivity of nodulation to ethylene might have been affected in supernodulation mutants.

The evolution of growth, nodulation, nitrogen fixation, and activities of root-nodule enzymes related to sucrose breakdown (sucrose synthase, alkaline invertase), pentose phosphate pathway (glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase), malate dehydrogenase, phosphoenolpyruvate carboxylase, and NADP-dependent isocitrate dehydrogenase, were followed over the complete life-cycle of faba bean in a growth chamber. The aim was to study the ontogenic changes of these parameters to obtain information on the carbon metabolism in nodules ofVicia faba, an amide-exporting legume. The maximum values of the relative growth rate and the specific acetylene-reducing activity were registered during the vegetative period. At pod-filling, the specific and total acetylene-reducing activity per plant declined in parallel with the enzyme activities of carbon metabolism. Contrary to reports for other legume species, inV. fabaroot nodule activity of sucrose synthase exceeded alkaline invertase values by 2-fold or more during the vegetative period. The activity of the two enzymes was similar at flowering and pod formation. The enzymes of carbon metabolism registered two maxima, one before and one after a trough (day 32), which marked the change from the vegetative to the reproductive period.

Summary Root ethylene biosynthesis has been studied in soybean (Glycine max [L.] Merr.) cv. Bragg plants and its supernodulating (nts382 and nts1007) and non-nodulating (nod49 and nod139) mutants. Regardless of NO3 treatment, inoculation with Bradyrhizobium japonicum significantly increased root ethylene evolution rate, reaching a plateau between 24 and 48 h after inoculation, with the rates being significantly higher in 8 mmol L−1 fed roots (high) than in those given 1 mmol L-1 (low) during the time of experiment. This Inoculation Stimulated Ethylene Release (ISER) response appears to be related to the infection process and nodule development, as treatment with Ag+ (an inhibitor of ethylene action) at the moment of inoculation markedly increased nodule number of Bragg plants under both high and low NO3 concentrations. Compared with the parental Bragg, the near-isogenic nodulating mutants used in this study showed normal ethylene biosynthesis ability (ethylene evolution and ACC oxidase activity), although significant quantitative differences were detected among them. Whether these differences are causally related to the nodulation phenotype is not known. Our previous observations on the involvement of endogenous ethylene in the control of nodule number in alfalfa are therefore also applicable to soybean, a determinate nodule type legume. The results further suggest that effects other than an alteration of ethylene biosynthesis might have also been caused by the nts mutations.

This study was conducted to obtain information on the properties of the nitrate (NO3 ‐) uptake system in Vicia faba. The results showed that in plants grown in the absence of NO3 ‐, they cannot absorb it upon initial exposure to this anion. When this plant makes contact with environmental NO3 ‐, NO3 ‐uptake by the roots is progressively induced. However, in NO3 ‐‐grown plants, the uptake system is yet induced so they had the ability to take up NO3 ‐ at high rates from the beginning. The Michaelis’ constant (K,M) and maximum uptake rate (Vmax) were estimated from measurements of NO3 ‐ depletion in the uptake medium. The apparent KM value for net NO3 ‐ uptake in induced V. faba plants was 60 μM and the corresponding Vmax 0.44 umol NO3 ‐ (g FW)‐1 h‐1. This last value was low compared with that of other species, while KM is in the range for other higher plants. From the results of our experiments at low and high NO3 ‐ concentrations, we discuss the possibility of the existence of two NO3 ‐ uptake sys...

The short term effect of NO 3 − (12 mM) on nitrate reductase (NR, EC 1.6.6.1) activity has been studied in the roots, nodules and leaves of different genotypes of Vicia faba L. at the end of vegetative growth. Root and leat NR activity responded positively to NO 3 − , while nodule activity, where detected, proved to he strongly inhibited. The withdrawal of this NO 3 − from the solution consistently reduced activity in the roots and leaves but, surprisingly, promoted a significant increase in nodule activity, which matched or surpassed that of control plants. On the other hand, nodules developed in the presence of 8 mM NO 3 − expressed an on average 141% higher level of NR activity than did controls. This effect was observed even in nodules with negligible control activity. In any case, a naturally occurring mutant (VF17) lacking root and nodule NR activity is described. The results indicate that in V. faba, the effects of NO 3 − and plant genotype on NR activity depended on plant organ and time of NO 3 − application, but the distribution of NO 3 − reduction through the plant was mainly dependent on plant genotype, and to a lesser extent on NO 3 − supply and plant age

To study liver lesions in morbidly obese patients who underwent liver biopsy at the time of bariatric surgery to define histological lesions, especially inflammatory infiltrate, diagnostic categories and the possible influence of gender in this respect.110 biopsies (36 males-M- and 76 females -F-) were evaluated and categorised, according to the NAS (NAFLD -non alcoholic fatty liver disease- Activity Score) system and other criteria, as non-NAFLD (15.5%, F predominance), non-alcoholic steatohepatitis (NASH) (16.5%, M predominance), non-alcoholic hepatosteatosis (NAHS) (21%, F predominance) and, the most numerous group, NASH-borderline (NASH-BORD) (47%), with three subgroups, characterised by centrozonal lesions, portal area preferential involvement or affecting both areas. The predominant form of hepatocytesteatosis was mixed with a multivesicular component that was present in most cases with fibroinflammatory portal involvement. Nuclear glycogenosomes were found in greater number of biopsies in patients in the third and sixth decades. Portal inflammation was present in a large number of cases (M predominance); the application of immunohistochemical techniques (myeloperoxidase and CD68 antibodies) to evaluate lobular inflammation revealed "surgical hepatitis" in one third of the cases, and the presence of microgranulomas (CD68+) (M predominance), which were more abundant with increasing lesion severity.Portal inflammation and multivesicular hepatocytesteatosis are highly prevalent in morbidly obese patients. This study identifies a new subtype of NASH-BORD characterized by centrizonal and porto-periportal area involvement and the existence of liver biopsies without steatosis. CD68+ microgranulomas constitute an unequivocal marker of lobular inflammation in surgical biopsies and of lesion severity, which is gender-related.

Twenty-nine genotypes of Vicia faba were grown in the presence or absence of NO3− to study variability in root and nodule nitrate reductase (NR, EC 1.6.6.1) and nodule cytosolic glutamine synthetase (GS, EC 6.3.1.2) activities. These V. faba lines apparently lack constitutive root NR activity (NRA), whereas inducible activity was detected in all of them except line VF17. Although a marked genotypic variability was found for this activity (F-value = 400), the major factor affecting its expression was nitrate (95% of the total effect observed). Most of the lines, however, showed appreciable rates of constitutive NRA in their nodules, that further declined with 4 mM NO3−. High genotypic variability was also found for the level of GS activity from the plant fraction of V. faba nodules. This activity, little affected by 2 mM NO3−, was generally declined by 4 m m for a week at the end of the experiment. No correlation was found between the activities measured here and measurements of symbiotic performance. Nodule NR, however, correlated inversely with both GS and nodule protein content.

The authors report an unusual case of flexor tenosynovitis, severe carpal tunnel syndrome, and triggering at the carpal tunnel as the first manifestation of gout. A 69-year-old man presented with digital flexion contracture and severe carpal tunnel syndrome of his right hand and was treated surgically. A flexor tenosynovectomy and a median nerve neurolysis were performed through an extended carpal tunnel approach. The sublimis and the profundus tendons were involved. Partial ruptures and multiple whitish lesions suggestive of tophacceous infiltration of the flexor tendons were seen. Macroscopically, the removed synovial tissue was involved by multiple whitish nodules that were milimetric in size and was suggestive of monosodium urate crystals deposits. By light microscopy examination, numerous nonnecrotizing granulomas of different sizes were observed that were compounded by large aggregations of acellular nonpolarized material, surrounded by epithelioid histiocytes, mononuclear cells, and foreign body multinucleated giant cells. Postoperatively, the patient recovered with resolution of the median nerve symptoms and a near-to-full range of motion of the affected digits. To the authors’ knowledge, this patient is the first case report with flexor tendons tophacceous infiltration as the first clinical sign of gout. Gouty flexor tenosynovitis can occur in the absence of a long history of gout. A high index of suspicion is paramount to the initiation of proper management. Operative treatment of gouty flexor tenosynovitis is mandatory to debulk tophaceous deposits, improve tendon gliding, and decompress nerves. Routine uric acid determination could be helpful in the preoperative evaluation of patients with flexor tenosynovitis.

Rabbit does nurse their pups once a day with circadian periodicity and pups ingest up to 35% of their body weight in milk in 5 min. In the doe, there is a massive release of prolactin. We hypothesised that periodic suckling synchronises dopaminergic populations that control prolactin secretion. We explored this by immunohistochemical colocalisation of PER1 protein, the product of the clock gene Per1 on tyrosine hydroxylase (TH) cells in three dopaminergic populations: tuberoinfundibular dopaminergic (TIDA), periventricular hypophyseal dopaminergic (PHDA) and incertohypothalamic dopaminergic (IHDA) cells. PER1/TH colocalisation was explored every 4 h through a complete 24-h cycle at postpartum day 7 in does that nursed their pups either at 10.00 h (ZT03) or at 02.00 h (ZT19; ZT0 = 07.00 h, time of lights on). Nonpregnant, nonlactating females were used as controls. In control females, there was a rhythm of PER1 that peaks at ZT15. By contrast, in nursed does, the PER1 peak shifted in parallel to scheduled nursing in TIDA and PHDA cells but not in IHDA cells, which are not related to the control of prolactin. Next, we determined that the absence of suckling for 48 h significantly decreases the number of PER1/TH colocalised cells in PHDA but not TIDA cells. Locomotor behaviour in control subjects was maximal at around the time of lights on but, in nursed females, shifted at around the time of scheduled nursing. Finally, in the suprachiasmatic nucleus, there is a maximal expression of PER1 at ZT11 in the three groups. However, this maximal expression was significantly lower in the nursed groups in relation to the control group and in the groups deprived of nursing for 48 h. We conclude that suckling synchronises dopaminergic cells related to the control of prolactin and appears to be a nonphotic stimulus for the suprachiasmatic nucleus.

Hygroscopic expansion of resin materials is a common phenomena due to water adsorption into the resin matrix. This expansion is dependent upon the chemical structure of the material. Water sorption of resin dental material may contribute to stress release immediately after polymerization shrinkage has occurred. The aim of this study was to evaluate the influence of water storage on nanohybrid composite by assessment of marginal enamel sealing of restorations.30 human teeth extracted for periodontal or orthodontic reasons were used in these study. Cavities were prepared and restored using a nanohybrid composite (Ceramix Mono, Dentsply DeTrey) and a total-etch adhesive system (PrimeBond NT, Dentsply DeTrey). The teeth were then randomly divided in three groups which were stored for various times in deionized water (one hour, 24 hours and 7 days). After the storage period, the teeth were immersed in methylen blue 1% for 24 h. Then specimens were axially cut and the dye penetration within the occlusal enamel interface was evaluated using optic microscope.Kruskal-Wallis test showed significant differences of dye penetration between the long-term hydrated groups and the group hydrated for only one hour (p0.05). The mean value of dye penetration decreased from 0.04 mm to 0.1 mm after water storage for both 24 hours and 7 days. However, good sealing in enamel margins of restorations was observed even without hydration.Our results confirm that nanohybrid composites used with total etch adhesives systems have good ability to seal the enamel margins and water sorption can improve this sealing.

Nitrate reductase activity (NRA; EC 1.6.6.1) was measured in leaves, stems and roots of Pisum sativum cv. Lincoln supplied with different nitrate concentrations and inoculated with selected Rhizobium leguminosarum strains. As a control, noninoculated plants were grown in the same nutrient medium. NRA was determined by an in vivo‐nitrate assay. Although differences in tissue NRA were mainly related to nitrate concentration in the growing medium, nodulation much affected the NRA in the different plant organs, especially in root. An increased proportion of total plant NRA occurred in the leaves and stems as nitrate concentration was increased. Nitrate accumulation in leaves, stems and roots was correlated with the concentration of this ion in the nutrient solution. Nodulation also affects the nitrate accumulation in the different plant organs.

Previously, we reported (a) a positive correlation between the nitrate concentrations in growth medium and ethylene evolved from uninoculated and inoculated alfalfa (Medicago sativa) roots and (b) a negative correlation between ethylene evolution and nodulation. Here, we report that the inhibitory effect of NO(3) (-) on nodulation of alfalfa can be eliminated by the ethylene inhibitor aminoethoxyvinylglycine (AVG). This effect was probably related to the strong inhibition (90%) of ethylene biosynthesis caused by AVG in these inoculated and NO(3) (-)-treated roots. These results support our hypothesis that the inhibitory effect of NO(3) (-) is mediated through the phytohormone ethylene. A possible role of endogenous ethylene in the autoregulation of nodulation also is discussed. AVG at 10 micromolar significantly (P < 0.05) increased total nitrogenase activity (acetylene reduction) in 2.5 and 5 millimolar NO(3) (-)-fed plants probably as a result of the very high stimulation of nodulation.

This growth chamber study was designed to determine rates of nitrogen fixation, growth, productivity and concentrations of nitrogen and phosphorus during vegetative growth, flowering and the beginning of the fruiting and ripening period in Pisum sativum plants supplied with different concentrations of nitrate and nodulated by various strains of Rhizobium leguminosarum. Noninoculated control plants were grown under the same nutritional conditions. Nodulated and unnodulated plants responded differently to treatment. The effects of inoculation with Rhizobium and the nitrate treatments on the parameters of growth and nitrogen content varied with plant age. Although the presence of nitrate in the culture medium inhibited nodulation and acetylene reducing activity (ARA), the different Rhizobium strains used in the inoculations led to variations in tolerance to combined nitrogen.

Activities of nitrate reduction enzymes, nitrate reductase activity (NRA) and nitrite reductase activity (NiRA) from roots and nodules of 5 mutant genotypes and one commercial cultivar (Alameda) of faba bean (Vicia faba L. var. minor) grown in the presence of N2 alone or with additional NO−3 in the medium have been studied. A naturally occurring mutant (VFM109) with impaired ability to reduce nitrate in its nodules is described. All the other cultivars of V. faba showed nodule NRA, although the range was very wide, from almost negligible (VFM72) up to 2 μmol h−1 (g FW)−1. This activity was entirely of plant origin. Root NRA also ranged widely accross cultivars. However, the level of activity expressed as well as the response of NRA to nitrate followed a pattern opposite to that observed in nodules. Roots and nodules of all cultivars showed very high rates of NiRA, respectively 50 and 150-fold higher than NRA, thus precluding accumulation of nitrite in these tissues. Root enzymes were significantly stimulated by nitrate while negative (NRA) or little effect (NiRA) was found for nodules. Nitrate and nitrite reduction are carried out by inducible enzymes in roots of V. faba and by constitutive enzymes in nodules, indicating that there may be different forms of these enzymes in each tissue. Differences in the plant genotype were a major cause of the variability in nitrate and nitrite reduction by nodulated root systems of V. faba.

We describe a capillary zone electrophoresis method coupled to electrospray ionization (ion trap) mass spectrometry (CZE-ESI-MS) for the identification and determination of choline and atropine compounds in hairy root extracts from Cannabis sativa L. Fused-silica capillary and an alkaline solution of 20 mM ammonium acetate at pH 8.5 are used being the most suitable for the analysis of choline and atropine in less than 10 min. Under the optimized conditions, including CE and ESI-MS parameters, the method resolved both compounds with very high sensitivity. The system exhibited good linear response in the range of 25-500 mg/L and 500-1000 microg/L for choline and atropine, respectively. The detection limit of choline was 18 mg/L and 320 microg/L for atropine. Finally, the developed method was applied to the analysis of these compounds in transgenic root cultures of Cannabis sativa L.

Semisolid olive-mill residues, pine chips, and mixtures of both residues contain phytotoxic components capable of inhibiting germination and vegetative growth in plants. Solid-state cultures of Phanerochate flavido-alba on pine chips or mixtures of both residues reduce these phytotoxic effects in fermented substrates. The phenol and lipid contents in cultures detoxified by this fungus also decreases.

Geology ,QE1-996.5 - Abstract
The primary scientific objective of MexiDrill, the Basin of Mexico Drilling Program, is development of a continuous, high-resolution ∼400 kyr lacustrine record of tropical North American environmental change. The field location, in the densely populated, water-stressed Mexico City region gives this record particular societal relevance. A detailed paleoclimate reconstruction from central Mexico will enhance our understanding of long-term natural climate variability in the North American tropics and its relationship with changes at higher latitudes. The site lies at the northern margin of the Intertropical Convergence Zone (ITCZ), where modern precipitation amounts are influenced by sea surface temperatures in the Pacific and Atlantic basins. During the Last Glacial Maximum (LGM), more winter precipitation at the site is hypothesized to have been a consequence of a southward displacement of the mid-latitude westerlies. It thus represents a key spatial node for understanding large-scale hydrological variability of tropical and subtropical North America and is at an altitude (2240 m a.s.l.), typical of much of western North America. In addition, its sediments contain a rich record of pre-Holocene volcanic history; knowledge of the magnitude and frequency relationships of the area's explosive volcanic eruptions will improve capacity for risk assessment of future activity. Explosive eruption deposits will also be used to provide the backbone of a robust chronology necessary for full exploitation of the paleoclimate record. Here we report initial results from, and outreach activities of, the 2016 coring campaign.

The levels of different cytokinins, indole-3-acetic acid (IAA) and abscisic acid (ABA) in roots of Glycine max [L.] Merr. cv. Bragg and its supernodulating mutant nts382 were compared for the first time. Forty-eight hours after inoculation with Bradyrhizobium, quantitative and qualitative differences were found in the root's endogenous hormone status between cultivar Bragg and the mutant nts382. The six quantified cytokinins, ranking similarly in each genotype, were present at higher concentrations (30-196% on average for isopentenyl adenosine and dihydrozeatin riboside, respectively) in mutant roots. By contrast, the ABA content was 2-fold higher in Bragg, while the basal levels of IAA [0.53 micromol (g DW)(-1), on average] were similar in both genotypes. In 1 mM NO3(-)-fed Bragg roots 48 h post-inoculation, IAA, ABA and the cytokinins isopentenyl adenine, and isopentenyl adenosine quantitatively increased with respect to uninoculated controls. However, only the two cytokinins increased in the mutant. High NO3- (8 mM) markedly reduced root auxin concentration, and neither genotypic differences nor the inoculation-induced increase in auxin concentration in Bragg was observed under these conditions. Cytokinins and ABA, on the other hand, were little affected by 8 mM NO3-. Root IAA/cytokinin and ABA/cytokinin ratios were always higher in Bragg relative to the mutant, and responded to inoculation (mainly in Bragg) and nitrate (both genotypes). The overall results are consistent with the auxin-burst-control hypothesis for the explanation of autoregulation and supernodulation in soybean. However, they are still inconclusive with respect to the inhibitory effect of NO3-.

Según la Organización de las Naciones Unidas para la Agricultura y la Alimentación, los cítricos dominan la producción mundial de todas las frutas. Por su posición geográfica, Ecuador tiene condiciones favorables de crecimiento para la producción de cítricos y la mayor parte del país tiene condiciones favorables para las plantas y sus relaciones con las condiciones ambientales. El objetivo de la presente investigación fue determinar la fenología reproductiva de la sutil de limón ( Citrus aurantifolia Swingle) bajo diferentes niveles de humedad del suelo.Un Asistente de Configuración de Base de Datos) usando un diseño de Bloque Completo Aleatorio aplicado y cuatro tratamientos y seis repeticiones se distribuyeron de la siguiente manera: tratamiento 1 [coeficiente de cultivo (Kc) 0.3], tratamiento 2 (Kc 0.5), tratamiento 3 (Kc 0,7) y tratamiento 4 (Kc 0,9). Se evaluó la calidad del fruto, peso de piel y pulpa, cantidad de semilla, contenido de jugo, grado Brix y diámetro polar y ecuatorial, y se ajustó la fenología a la codificación de la escala BBCH. No se encontraron diferencias estadísticamente significativas durante el estudio que resultaron de las lluvias que homogeneizaron todo el sustrato y mantuvieron la humedad del suelo.Establecimos que desde la fase fenológica de los primordios hasta la cosecha del fruto, hubo un intervalo de 138-140 d en el que el peso promedio del fruto (42. 62 g) fluctuó según el peso de la piel (7,65 g) , peso de la pulpa (34,73 g), número de semillas (5,05), cantidad de jugo (14,36 mL), grados Brix (5,5), diámetros polares y ecuatoriales (44,32 y 42, 12 mm, respectivamente) y la acidez titulable (6,54%). Concluimos que las Kcs propuestas en la presente investigación deben evaluarse durante la estación seca porque, en esta investigación, el riego fue inducido por Kc solo durante 2 meses después de las lluvias.

Resumen: Introducción: La información existente sobre el impacto de la gripe en la población infantil española es escasa. El presente trabajo pretende aumentar este conocimiento estudiando aspectos clave como la incidencia de hospitalización, clínica, comorbilidades y el estado vacunal en los niños hospitalizados. Métodos: Estudio retrospectivo, observacional, por revisión de historias clínicas, en menores de 15 años hospitalizados por gripe adquirida en la comunidad, confirmada microbiológicamente, durante 2 temporadas gripales (2014-2015 y 2015-2016). El estudio se realizó en 10 hospitales de 6 ciudades, que atienden aproximadamente al 12% de la población infantil española. Resultados: Fueron hospitalizados 907 niños con diagnóstico principal de gripe (447 50%) de los casos. Una gran parte de las formas graves de gripe en población infantil podrían ser evitada si se cumplieran las indicaciones actuales de vacunación. Abstract: Introduction: There are only a limited number of studies on the impact of influenza in the Spanish child population. The present work intends to increase this knowledge by studying some key aspects, such as the incidence of hospital admissions, clinic variables, comorbidities, and the vaccination status in the hospitalised children. Methods: A retrospective, observational study was conducted by reviewing the medical records of children under 15 years and hospitalised due to community acquired influenza confirmed microbiologically, during 2 ́flu seasons (2014-2015 and 2015-2016). The study was carried out in 10 hospitals of 6 cities, which represent approximately 12% of the Spanish child population. Results: A total of 907 children were admitted to hospital with main diagnosis of influenza infection (447 10 years. Admission to the PICU was required in 10% (92) of the cases, mainly due to acute respiratory failure. Conclusion: Influenza continues to be an important cause of hospitalisation in the Spanish child population. Children 50%) of the cases. Many of the severe forms of childhood influenza that occur today could be avoided if current vaccination guidelines were met.

Objetivo: Describir la asociación entre el control del asma y la adherencia al tratamiento en los pacientes del Hospital Nacional Dos de Mayo en los años 2019-2020. Materiales y métodos: Se realizó un estudio cuantitativo, descriptivo y retrospectivo, de tipo clínico, durante el periodo 2019-2020, en pacientes asmáticos del Hospital Nacional Dos de Mayo (HNDM) para evaluar la relación entre control del asma y adherencia al tratamiento en los pacientes atendidos en el Consultorio de Asma del Servicio de Neumología. La información fue recolectada de las historias clínicas y los datos registrados fueron los siguientes: test de adherencia a los inhaladores (TAI), test de control de asma (ACT), edad, sexo, tratamiento instaurado, tiempo de enfermedad y la valoración nutricional, a través de la revisión de historias clínicas. El análisis estadístico se realizó con el software IBM SPSS Statistics versión 22, y para determinar la asociación se realizó la prueba estadística X2. Resultados: Se evaluaron 187 pacientes mediante historias clínicas, 84 hombres (44,92 %) y 103 mujeres (55,08 %). El promedio de edad fue de 59,42 ± 15,08 años (solo los mayores de edad fueron considerados en el estudio). Mediante el análisis de los datos de las historias clínicas, se determinó que había 86 pacientes controlados (45,99 %) y que 48 pacientes eran adherentes (25,67 %). El corticoide inhalado (CSI) fue el tratamiento más usado (50,80 %). El tipo inconsciente fue la modalidad más frecuente de paciente incumplidor (64,17 %). El promedio de tiempo de enfermedad, en años, estuvo en 21,78 ± 16,75. Conclusiones: El 75% de los pacientes asmáticos con adherencia al tratamiento controlan la enfermedad.

In present work it is pretended to estimate elastic parameters of beams through the combined use of precision geomatic techniques (laser scanning) and structural behaviour simulation tools. The study has two aims, on the one hand, to develop an algorithm able to interpret automatically point clouds acquired by laser scanning systems of beams subjected to different load situations on experimental tests; and on the other hand, to minimize differences between deformation values given by simulation tools and those measured by laser scanning. In this way we will proceed to identify elastic parameters and boundary conditions of structural element so that surface stresses can be estimated more easily.

El fútbol es un fenómeno social, cultural, mediático y económico. Existen numerosas investigaciones sobre su influencia en quiénes lo practican. No obstante, el objetivo de esta investigación fue explorar su influencia sobre valores sociales relacionados con el fair play, la igualdad de género y la relación medios-fines, en alumnado de primaria, por ser aspectos que pueden reflejarse en algunas problemáticas sociales. La población objeto de estudio fue alumnado de sexto curso. Es un estudio descriptivo correlacional transversal. Las fuentes de obtención de información utilizadas fueron, un cuestionario y un grupo de discusión. Los resultados indicaron que el sexo y la práctica de fútbol federado influyen en el fair play, afán por la victoria e igualdad de género, siendo los chicos y el alumnado practicante de fútbol más proclive a conductas anti fair play, más resultadistas y con una visión más negativa hacia la figura de la mujer en el fútbol.

We present results of analysis of biological (diatoms and ostracodes) and non-biological (Ti, Ca / Ti, total inorganic carbon, magnetic susceptibility) variables from an 8.8 m long, high-resolution (~ 20 yr sample−1) laminated sediment sequence from Lake Santa María del Oro (SMO), western Mexico. This lake lies at a sensitive location between the dry climates of northern Mexico, under the influence of the North Pacific subtropical high-pressure cell and the moister climates of central Mexico, under the influence of the seasonal migration of the intertropical convergence zone and the North American monsoon (NAM). The sequence covers the last 2000 years and provides evidence of two periods of human impact in the catchment, shown by increases in the diatom Achnanthidium minutissimum. The first from AD 100 to 400 (Early Classic) is related to the shaft and chamber tombs cultural tradition in western Mexico, and the second is related to Post-Classic occupation from AD 1100 to 1300. Both periods correspond to relatively wet conditions. Three dry intervals are identified from increased carbonate and the presence of ostracodes and aerophilous Eolimna minima. The first, from AD 500 to 1000 (most intense during the late Classic, from AD 600 to 800), correlates with the end of the shaft and chamber tradition in western Mexico after ca. AD 600. This late Classic dry period is the most important climatic signal in the Mesoamerican region during the last 2000 years, and has been recorded at several sites from Yucatan to the Pacific coast. In the Yucatan area, this dry interval has been related with the demise of the Maya culture at the end of the Classic (AD 850 to 950). The last two dry events (AD 1400 to 1550 and 1690 to 1770) correspond with the onset of, and the late, Little Ice Age, and follow largely the Spörer and Maunder minima in solar radiation. The first of these intervals (AD 1400 to 1550) shows the most intense signal over western Mexico; however this pattern is different at other sites. Dry/wet intervals in the SMO record are related with lower/higher intensity of the NAM over this region, respectively.
