AimsLeaf chlorophyll (Chl) is a fundamental component and good proxy for plant photosynthesis. However, we know little about the large-scale patterns of leaf Chl and the relative roles of current environment changes vs. plant evolution in driving leaf Chl variations.LocationsThe east to west grassland transect of the Tibetan Plateau.MethodsWe performed a grassland transect over 1,600 km across the Tibetan Plateau, measuring leaf Chl among 677 site-species.ResultsLeaf Chl showed a significantly spatial pattern across the grasslands in the Tibetan Plateau, decreasing with latitude but increasing with longitude. Along with environmental gradient, leaf Chl decreased with photosynthetically active radiation (PAR), but increased with water availability and soil nitrogen availability. Furthermore, leaf Chl also showed significant differences among functional groups (C4 &gt; C3 species; legumes &lt; non-legume species), but no difference between annual and perennial species. However, we surprisingly found that plant evolution played a dominant role in shaping leaf Chl variations when comparing the sum and individual effects of all the environmental factors above. Moreover, we revealed that leaf Chl non-linearly decreased with plant evolutionary divergence time. This well-matches the non-linearly increasing trend in PAR or decreasing trend in temperature during the geological time-scale uplift of the Tibetan Plateau.Main ConclusionThis study highlights the dominant role of plant evolution in determining leaf Chl variations across the Tibetan Plateau. Given the fundamental role of Chl for photosynthesis, these results provide new insights into reconsidering photosynthesis capacity in alpine plants and the carbon cycle in an evolutionary view.

PurposeThis paper aims to explore the safety and feasibility of a single-hole laparoscopic myomectomy through an abdominal scar approach.MethodThe clinical data of seven patients who underwent the single-hole laparoscopic myomectomy via the abdominal scar approach from January to November 2021 in the Department of Gynecology, the Affiliated Changzhou No. 2 People's Hospital of Nanjing Medical University, were studied retrospectively. The duration of operation, the intraoperative blood loss, the decrease of postoperative hemoglobin, and the postoperative visual analogue score (0 points: no pain, 10 points: maximum pain) were recorded.ResultsAll seven patients received the operation successfully, without changing to the conventional laparoscopic operation or open appendectomy. The average blood loss was 101.42 ± 7.89 ml, the average length of hospital stay was 5 ± 0.53 days, the average operation duration was 130 ± 26.86 min, and the 24-h pain score was 1.57 ± 0.53. The seven patients had no intraoperative or postoperative complications and no damage to the ureter or bladder. All patients could urinate spontaneously without urinary retention or urinary tract infection after catheter removal. No analgesic drugs were used after the operation.ConclusionThe single-hole laparoscopic myomectomy via the abdominal scar approach is a more aesthetic and feasible option for eligible patients, but more cases and studies are needed for further confirmation.

Objetivo: analizar la importancia de la percepción de despedida y/o de la despedida real en una muestra de dolientes, para la realización de un duelo saludable
Método: participaron 183 asistentes a las Jornadas de Duelo de un centro sociosanitario de la Comunidad de Madrid, todos con experiencia de duelo, media de 50 años (DT=16), 81% (149) mujeres. Se entregó un cuestionario incluyendo variables sociodemográficas, alrededor del duelo, circunstancias del fallecimiento, percepción de despedida y forma/s y desarrollo de la despedida. Se realizó una regresión lineal múltiple por pasos hacia atrás con el efecto de la despedida como variable dependiente.
Resultados: el modelo ajustado permitió una estimación correcta sobre el efecto de la despedida del 55% de los casos (R2 corregida=0.548), siendo la variable con más peso en el pronóstico la percepción de despedida (Beta=-0.403), seguida de la percepción de elaboración del duelo (Beta=0.327), el hecho de que haya habido una despedida explícita y el nivel de conciencia de fallecimiento por parte del fallecido (Beta=0.175).
Conclusiones: la percepción de realización de una despedida en cualquiera de sus formatos es una variable de gran peso para la adecuada realización del proceso de duelo. Aunque el efecto es más positivo en las despedidas explícitas, verbalizadas, previas al fallecimiento y por iniciativa del doliente, también las despedidas implícitas, no verbalizadas, por iniciativa del fallecido y/o póstumas tienen efecto en la evolución del proceso de duelo

1. Background: Peri-implantitis affects a high percentage of patients treated with dental implants. Among the risk factors that can cause this pathology, limited evidence exists regarding the absence of keratinized mucosa. The main objective of this study was to compare the amount of keratinized mucosa around healthy implants versus implants in patients with peri-implantitis, in order to analyze its influence on esthetics and the development of this pathology, and to study the possible influence of keratinized mucosa on various clinical parameters. 2. Methods: A retrospective case-control study was carried out in which 203 implants were evaluated, 103 of which presented a healthy peri-implant state, versus 100 which had peri-implantitis. The following elements were recorded: keratinized mucosa, recession, plaque index, bleeding, suppuration, probing depth, and bone level. 3. Results: Keratinized mucosa was present in 51% of the peri-implantitis group versus 97.1% of the healthy implants. In implants without keratinized mucosa, both recession and plaque index, bleeding on probing (96.2%), suppuration (57.7%), mean probing depth and bone level were higher. Implants without keratinized mucosa presented worse esthetics. 4. Conclusions: Absence of Keratinized mucosa around dental implants seems to be associated with the appearance of peri-implantitis modifying certain clinical parameters: there is a greater probability of recession, bleeding, suppuration, deficient hygiene, greater probing depth and greater bone loss in implants without keratinized mucosa.

Published: July 2022

The performance of a fuel cell stack is affected by the operating temperature of the stack. The thermal management subsystem of a multi-stack fuel cell system (MFCS) is particularly significant for the operating temperature control of each stack in the MFCS. To study the influence of different topologies of a MFCS thermal management subsystem, this paper proposes and establishes two different topologies. Firstly, the integrated topology is proposed. Secondly, seven component models, namely the mixer, thermostat, radiator, tank, pump, bypass value, and proton exchange membrane fuel cell stack temperature models, are described in detail. Finally, the performance of the two topologies of the MFCS thermal management subsystem under two working conditions, steady (200 A) and variable (China heavy-duty commercial test cycle, C-WTVC), is compared. Furthermore, there are two evaluating indicators, including the stability duration and deviation of the operating temperatures of the single stack in the MFCS. Results show that when the MFCS operates under steady working conditions, the integrated topology is superior in operating temperature control accuracy (ΔT<0.5 K), while the distributed topology is superior in the adjustment process (t ≤ 100 s). Moreover, when the MFCS operates under variable working conditions, the distributed topology is superior in operating temperature control accuracy.

Several activities in the agriculture sector lead to the accumulation of Nickel (Ni) in soil. Therefore, effective and economical ways to reduce soil bioavailability of Ni must be identified. Five isolates of Rhizobium leguminosarum biovar Viceae (ICARDA 441, ICARDA 36, ICARDA 39, TAL–1148, and ARC–207) and three bacterial strains (Bacillus subtilis, B. circulance, and B. coagulans) were evaluated for tolerance and biosorption of different levels of Ni (0, 20, 40, 60, and 80 mg L−1). Pot experiments were conducted during the 2019/2020 and 2020/2021 seasons using four inoculation treatments (inoculation with the most tolerant Rhizobium (TAL–1148), inoculation with the most tolerant Rhizobium (TAL–1148) + B. subtilis, inoculation with the most tolerant Rhizobium (TAL–1148) + B. circulance, and inoculation with the most tolerant Rhizobium (TAL–1148) + B. coagulans) under different levels of Ni (0, 200, 400, and 600 mg kg−1), and their effects on growth, physiological characteristics, antioxidant enzymes, and Ni accumulation in faba bean plants (Vicia faba C.V. Nobaria 1) were determined. The results showed that Rhizobium (TAL–1148) and B. subtilis were the most tolerant of Ni. In pot trials, inoculation with the most tolerant Rhizobium TAL–1148 + B. subtilis treatment was shown to be more effective in terms of growth parameters (dry weight of plant, plant height, number of nodules, and N2 content), and this was reflected in physiological characteristics and antioxidant enzymes under 600 mg kg−1 Ni compared to the other treatments in the 2019/2020 season. In the second season, 2020/2021, a similar pattern was observed. Additionally, lower concentrations of Ni were found in faba bean plants (roots and shoots). Therefore, a combination of the most tolerant Rhizobium (TAL–1148) + B. subtilis treatment might be used to reduce Ni toxicity.

Atualmente, o estilo de vida antropomorfizado dos animais contribui para o intenso desenvolvimento da obesidade. A hiperlipidemia se apresenta como um dos efeitos deletérios do excesso de peso sobre a saúde dos cães, porém sendo pouco investigada. O termo hiperlipidemia refere-se ao aumento da concentração de lipídeos (colesterol, triglicérides ou ambos) séricos. Este estudo teve como objetivo realizar uma análise retrospectiva e estatística em animais que foram considerados obesos mediante inspeção de condição de escore corporal,visando correlacionar a obesidade com a presença de hiperlipidemias. Foram revisadas e analisadas 70 amostras sanguíneas de pacientes atendidos no Hospital Veterinário São Judas de outubro de 2018 a outubro de 2020 que já haviam realizado análises bioquímicas no Hospital; foram retiradas as informações destinadas a exames bioquímicos de triglicérides, colesterol e peso juntamente com a avaliação de condição de escore corporal (ECC) que foi feita em consulta clínica. Constatou-se que 24 (34,2%) amostras apresentaram resultados acima dos valores de referência para colesterol e triglicérides. Dentre esses 24 cães, 21 (87,5%) apresentaram ECC igual 7 ou maior, representando sobrepeso e/ou obesidade. Nenhum dos cães havia comparecido para atendimento pelo mesmo motivo e não houve queixa dos tutores tratando-se de sobrepeso, portanto, as alterações encontradas em exames bioquímicos foram um achado clínico laboratorial. Dos 21 cães componentes do grupo que apresentaram distúrbios metabólicos, 12 cães (57,2%) apresentaram ambos os valores de triglicérides e colesterol aumentados, apresentando então uma hiperlipidemia; 5 (23,8%) cães apresentaram hipercolesterolemia e 4 (19%) apresentaram hipertrigliricedemia. Essas alterações quando comparadas com um grupo controle de 19 animais sem alterações dignas de nota, revelaram valores de significância estatística, sugerindo alta frequência de hiperlipidemia em cães obesos, classificada como moderadamente elevados com importância clínica, havendo prevalência nas fêmeas.

Для гидравлического расчета сетей водоотведения поверхностного стока в нашей стране более 60 лет используется концепция мгновенного отведения стока, образовавшегося в результате выпадения дождей. Для этого применялся и продолжает применяться метод «предельных интенсивностей», реализуемый с помощью методик, заложенных в ТУиН 141-56, СНиП II-Г.6-62, СНиП II-32-74, СНиП 2.04.03-85, СП 32.13330.2012, СП 32.13330.2018. Если продолжать руководствоваться этой концепцией, то для адаптации эксплуатируемых систем к фактическим современным условиям в большинстве случаев необходима перекладка всех сетей с увеличением диаметров труб, что реализовать практически невозможно не только с экономической, но и с технической и социальной точек зрения. В сложившейся ситуации назрела необходимость внедрения альтернативных направлений адаптации сетей водоотведения поверхностного стока, которые по сравнению с перекладкой всех сетей являются более экономически целесообразными. Среди них заслуживают внимания направления, предусматривающие снижение коэффициентов стока, задержание и удержание воды в системах водоотведения. Оценена эффективность этих направлений с применением численного моделирования и аналитических расчетов.
For the hydraulic calculation of storm sewer networks removing surface runoff in our country, the concept of immediate removal of runoff formed as a result of rainfall has been used for more than 60 years. With this aim, the method of «limiting intensities» has been used up nowadays, implemented with the help of the methods laid down in Norms and Technical Conditions for Design 141-56, SNiP II-G.6-62, SNiP II-32-74, SNiP 2.04.03-85, SP 32.13330. 2012, CP 32.13330.2018. If we continue to be guided by this concept, then in order to adapt the operated systems to the current conditions, in most cases relaying all the networks with larger pipe diameters would be required, which is practically impossible not only from the economic, but also from the technical and social point of view. In the current situation, introducing alternative solutions for adapting storm sewer networks is needed, which, in comparison with relaying all the networks, are more economically justifiable. Among them, noteworthy are the solutions that provide for the detention and retention of water in sewers, and for reducing runoff coefficients. The effectiveness of these solutions is estimated using numerical modeling and analytical calculations.
