Planting trees is popular, widely accepted and supported, resulting with many initiatives and commitments around the globe. At the same time, planting trees is questioned more and more and receive a lot of criticism. In this paper we consider the arguments of both sides and discuss them using a scientific evidence. Determination of restoration opportunities and restoration needs requires more intention to existing ecosystems and their use. Commitments and expectations need to be realistic to maintain constant support based on real results. Planting trees is not the best solution for carbon storage, but it is one of the best solutions available at this moment. Even if reduce anthropogenic CO2 emission to zero, we will need to plant trees. Planting trees can have both negative and positive effect on water availability and socio-economy, depending on restoration practice applied. Planting trees is definitely good, if it is done at appropriate site and with appropriate tree species and if it is based on proper planning and realistic expectations.

Abstract More tree species can increase the carbon storage capacity of forests (here referred to as the more species hypothesis) through increased tree productivity and tree abundance resulting from complementarity, but they can also be the consequence of increased tree abundance through increased available energy (more individuals hypothesis). To test these two contrasting hypotheses, we analyse the most plausible pathways in the richness-abundance relationship and its stability along global climatic gradients. We show that positive effect of species richness on tree abundance only prevails in eight of the twenty-three forest regions considered in this study. In the other forest regions, any benefit from having more species is just as likely (9 regions) or even less likely (6 regions) than the effects of having more individuals. We demonstrate that diversity effects prevail in the most productive environments, and abundance effects become dominant towards the most limiting conditions. These findings can contribute to refining cost-effective mitigation strategies based on fostering carbon storage through increased tree diversity. Specifically, in less productive environments, mitigation measures should promote abundance of locally adapted and stress tolerant tree species instead of increasing species richness.

Статья посвящена изучению сопутствующей патологии, у женщин репродуктивного возраста, обращающихся в стационар с жалобами на нарушения менструального цикла (НМЦ). Актуальность данной тематики не вызывает сомнения, так как с каждым годом в России и во всем мире регистрируется все большее количество случаев НМЦ. По мнению ряда авторов, данные нарушения могут составлять до 50% всех патологий женской половой сферы. Большой интерес представляет и изучение ряда сопутствующих заболеваний, которые могут отягощать течение НМЦ или наоборот, приводить к их развитию. Целью работы стал анализ разнообразной сопутствующей патологии при НМЦ, с выявлением основных причин нарушений менструального цикла у женщин фертильного возраста. Объектами исследования стали 300 пациенток, с диагнозом НМЦ, которые были разделены на 3 группы, в зависимости от уровня лечебного учреждения, где они проходили обследование - по 100 пациенток: проходивших обследование в больнице скорой медицинской помощи, обследующиеся в женской консультации и проходящие лечение сопутствующей онкопатологии в областном онкологическом диспансере. В дальнейшем проводилась дополнительное деление в каждой группе на 2 подгруппы, в зависимости от того был ли НМЦ впервые выявленным или повторно выявленным. В самой работе проводился подробный анализ сопутствующей патологии у женщин в зависимости от группы и их возраста. Определялись не только «пораженные» системы органов, но и проводился углубленный анализ по нозологиям. Работа интересна еще и тем, что в ней у всех пациенток на протяжении исследования определялся уровень стресса и наличие возможных депрессивных состояний. Определение наиболее вероятных причин НМЦ стало завершающим этапом исследования. Полученные данные могут приблизить практикующих акушеров-гинекологов к более полному пониманию различных нарушений менструального цикла, что в целом, положительно скажется на качестве и эффективности оказываемой медицинской помощи The article is devoted to the study of concomitant pathology in women of reproductive age who go to the hospital with complaints of menstrual irregularities (NMC). The relevance of this topic is beyond doubt, since every year in Russia and around the world an increasing number of cases of NMC are registered. According to a number of authors, these violations can account for up to 50% of all pathologies of the female genital area. Of great interest is the study of a number of concomitant diseases that can aggravate the course of NMC or, conversely, lead to their development. The aim of the work was to analyze a variety of concomitant pathologies in NMC, with the identification of the main causes of menstrual irregularities in women of fertile age. The objects of the study were 300 patients diagnosed with NMC, who were divided into 3 groups, depending on the level of the medical institution where they were examined - 100 patients each: who were examined in an emergency hospital, examined in an antenatal clinic and undergoing treatment for concomitant oncopathology in the regional oncological dispensary. Subsequently, an additional division was carried out in each group into 2 subgroups, depending on whether the NMC was newly detected or re-identified. In the work itself, a detailed analysis of comorbidities in women was carried out, depending on the group and their age. Not only the "affected" organ systems were identified, but an in-depth analysis of nosologies was also carried out. The work is also interesting in that during the study the level of stress and the presence of possible depressive states were determined in all patients. Determination of the most probable causes of NMC was the final stage of the study. The data obtained can bring practicing obstetricians and gynecologists closer to a more complete understanding of various menstrual irregularities, which, in general, will have a positive effect on the quality and effectiveness of medical care

Background: Ilexsaponin A1, one of the most representative triterpene saponin components in the roots of I. pubescens, showed its effects in anticoagulation and antithrombosis, attenuating ischemia-reperfusion-induced myocardial, angiogenesis and inhibiting phosphodiesterase. Objective: Reveal the key intestinal bacterial strains responsible for ilexsaponin A1 metabolism, and clarify their metabolic behavior. Methods: An accurate and sensitive LC-MS/MS method for the determination of “ilexsaponin A1 in General Anaerobic Medium (GAM) broth” was established and systematically validated. Then it was applied to screen and study the metabolic potential of the intestinal bacterial strains in an anaerobic incubation system. Results: Quantitation of ilexsaponin A1 could be performed within an analytical run time of 14.5 min, in the linear range of 2 - 2000 ng/ml. Enterobacter sakazakii, Bifidobacterium breve, Bifidobacterium adolescentis, Bifidobacterium catenulatum, and Bifidobacterium angulatum were identified to have a potential effect to metabolize ilexsaponin A1 to different extents; and further bacterial metabolic studies were performed to clarify their metabolic capacity and behavior. Conclusion: This paper contributes to a better understanding of the intestinal bacterial metabolism of ilexsaponin A1 and provides scientific evidence for its clinical application. Additionally, the importance of intestinal bacterial strains in the disposition of natural products was also highlighted.

The anaerobic treatment of municipal wastewater enables new applications for the reuse of wastewater. The effluent could be used for irrigation as the included nutrients are not affected by the treatment. Much more interesting now are renewable energies and the retrenchment of CO2 emission. With the anaerobic treatment of municipal wastewater, not only can the CO2 emission be reduced but “clean” energy supply can be gained by biogas. Most important for the sustainability of this process is the gathering of methane from the liquid effluent of the reactor, because the negative climate-relevant effect from the degassing methane is much higher than the positive effect from saving CO2 emission. In this study, UASB reactors were used with a flocculent sludge blanket for the biodegradation of the carbon fraction in the wastewater with different temperatures and concentrations. It could be shown that the positive effect is much higher for municipal wastewater with high concentrations in hot climates.

<p>Purpose: To research the influence of different densities of Platycladus orientalis plantation on the allocation characteristics of carbon storage in the ecosystem, the density regulation experiment on the Pinus massoniana plantation with different densities was carried out to discuss the change of the carbon storage of the ecosystem. Method: The density regulation experiment was carried out using random block design along contour line. Through the estimation of tree layer biomass of single Pinus massoniana, the determination of the carbon storage in the tree layer of Pinus massoniana, the estimation of the understory shrub, the grass layer, and the wood layer, the determination of carbon storage in vegetation and litter layer under forest, the determination of organic carbon content and carbon storage in the sample, and the carbon storage of the plantation ecosystem of different stand density sample plots, the effects of stand density on biomass and carbon storage of Pinus massoniana plantation were analyzed. Results: The results of average carbon storage per unit area of Pinus massoniana plantation was different stand densities are 94.11 t/tm2 (1679 plants t/hm2), 79.06 t/tm2 (2250 plants / hm2), 73.32 t/tm2 (2800 plants / hm2). With the increase of stand density, the proportion of carbon storage in Pinus massoniana plantation decreased. This is because the larger the stand density, the more trees with small and medium diameter are grown in the Pinus massoniana plantation. The average diameter at breast height of the stand is very small, and the biomass of single tree decreases. The density is most beneficial to the improvement of the carbon storage of the tree layer. Conclusions: Density regulation promotes the accumulation of carbon storage of the Pinus massoniana plantation and increases the carbon storage of understory vegetation, litter, and soil layer.</p>

Abstract The most promising way to prevent the explosive spread of COVID-19 infection is to achieve herd immunity through vaccination. It is therefore important to motivate those who are less willing to be vaccinated. To address this issue, we conducted an online survey of 6232 Japanese people to investigate age- and gender- dependent differences in attitudes towards COVID-19 vaccination and the underlying psychological processes. We asked participants to read one of nine different messages about COVID-19 vaccination and rate their willingness to be vaccinated. We also collected their 17 social personality trait scores and demographic information. We found that males 10-20 years old showed the minimum willingness to be vaccinated. We also found that prosocial traits are the driving force for young people, but the motivation in older people also depends on risk aversion and self-interest. Furthermore, an analysis of 9 different messages demonstrated that for young people (particularly males), the message emphasizing the majority’s intention to vaccinate and scientific evidence for the safety of the vaccination had the strongest positive effect on the willingness to be vaccinated, suggesting that the herding effect arising from the “majority + scientific evidence” message nudges young people to show their prosocial nature in action.
