The Ideal

Nanotechnology is a promising tool that has opened the doors of improvement to the quality of human’s lives through its potential in numerous technological aspects. Green chemistry of nanoscale materials (1–100 nm) is as an effective and sustainable strategy to manufacture homogeneous nanoparticles (NPs) with unique properties, thus making the synthesis of green NPs, especially metal nanoparticles (MNPs), the scientist’s core theme. Researchers have tested different organisms to manufacture MNPs and the results of experiments confirmed that plants tend to be the ideal candidate amongst all entities and are suitable to synthesize a wide variety of MNPs. Natural and cultivated Eucalyptus forests are among woody plants used for landscape beautification and as forest products. The present review has been written to reflect the efficacious role of Eucalyptus in the synthesis of MNPs. To better understand this, the route of extracting MNPs from plants, in general, and Eucalyptus, in particular, are discussed. Furthermore, the crucial factors influencing the process of MNP synthesis from Eucalyptus as well as their characterization and recent applications are highlighted. Information gathered in this review is useful to build a basis for new prospective research ideas on how to exploit this woody species in the production of MNPs. Nevertheless, there is a necessity to feed the scientific field with further investigations on wider applications of Eucalyptus-derived MNPs.

Foraging Preferences

We studied beavers’ dietary preferences and the role of several factors (such as plant species, size and anthropopression level) that affect the beavers’ foraging in northern Poland. Woody plants along the river were measured and classified according to species in six 100 m-long transects that were characterized by a diversified human disturbance level. Ivlev’s electivity index was used to present the beavers’ preferences for various plant species and sizes, and the generalized linear model was used to assess the significance of studied factors in beavers’ browsing choices. Most popular in the beavers’ diets were willows (Salix), maples (Acer) and alder (Alnus), but only willows and maples were preferred. We noted a decrease in the beavers’ foraging preference in parallel to an increase in the shoot diameter; plants with a diameter below 10 cm were preferred. All factors included in the generalized linear model (GLM) were significant in shaping the beavers’ foraging choices. A negative correlation between the shoot diameter and the human disturbance level was found, but the species composition of the browsed woody plants was the same in each transect. Beavers’ foraging preferences, as observed in our study, were similar to those described in the literature and confirmed the role of woody species and their diameters in shaping the beavers’ diet. We also suggested the potential role of anthropopression in the shaping of the beavers’ foraging behaviors.

Between 2000 and 2050, the number of new cancer patients diagnosed annually is expected to double, with an accompanying increase in treatment costs of more than $80 billion over just the next decade. Efficacious strategies for cancer prevention will therefore be vital for improving patients' quality of life and reducing healthcare costs. Judah Folkman first proposed antiangiogenesis as a strategy for preventing dormant microtumors from progressing to invasive cancer. Although antiangiogenic drugs are now available for many advanced malignancies (colorectal, lung, breast, kidney, liver, brain, thyroid, neuroendocrine, multiple myeloma, myelodysplastic syndrome), cost and toxicity considerations preclude their broad use for cancer prevention. Potent antiangiogenic molecules have now been identified in dietary sources, suggesting that a rationally designed antiangiogenic diet could provide a safe, widely available, and novel strategy for preventing cancer. This paper presents the scientific, epidemiologic, and clinical evidence supporting the role of an antiangiogenic diet for cancer prevention.

The mechanistic understanding of sweet taste chemoreception has been advanced by the microscopic and macroscopic studies of sweetener­water interactions. This approach has led to the concept of water mobility as a key to interpreting sweetness. The apparent specific volume of a solution is a determinant of its taste quality, as sweetness is known to be confined to the range 0.51­0.71 cm3 g-1. Thus, the "ideal" quality of the sugars is presumed to be due to their occupancy of the center of this range (i.e., 0.618 cm3 g-1). Most sweeteners elicit off-tastes and flavors and exhibit different apparent specific volumes. This leads to the conclusion that taste quality is broadly determined by the packing characteristics of sweet molecules among water molecules and the compactness of their hydration shells, expressed as their apparent specific isentropic compressibilities. The role of water can, therefore, be applied in modern attempts to optimize sweet taste quality, and different food salts can be explored as useful taste modifiers. Salts interact more strongly with water structure than do any other taste solutes, and it emerges that the ionic charge density is an important criterion. Such studies show how sweetener formulations are likely to improve within the next decade.

Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a common disorder. From a clinical and immunopathological point of view, different phenotypes and endotypes have been identified. As asthma is frequent comorbidity, biological agents for treating CRSwNP associated with asthma may be an attractive strategy. Biological agents have several mechanisms, such as antagonizing IgE, interleukin (IL) 4, IL-5, and IL-13. However, a workup is mandatory, mainly concerning pheno-endotyping. In this regard, clinical cytological grading (CCG) has been proposed as a useful tool to manage patients with CRSwNP as it allows us to define clinical and immunopathological phenotypes able to identify the ideal candidate for biologics. In particular, the mixed cellular pattern, such as eosinophils and mast cells, could be sensitive to anti-IL-4 agents. There is still a need for well-established indications, criteria of responsiveness, duration, and safety. Moreover, personalized medicine could be opportunely integrated and/or alternated with intranasal corticosteroids to prevent relevant adverse events.

ABSTRACT Under tropical and sub-tropical conditions, perennial woody plants most often encounter drought stress due to erratic rainfall, which has become compounded as result of recent climatic changes. Control of the efficiency and safety of water transport from roots to shoots is fundamental for plant survival under water stressed conditions. Lignin plays an important role in the life of terrestrial plants. Depending upon the stress, lignin plays protective, sustaining and disruptive roles in addition to its involvement in plant growth, development and defense responses. This review aims to present and summarize reported evidence on the possible role of lignin of plant tissue (in special woody species) in response to water limiting condition which is expected to increase because of environment changes.

PROBLEMS WITH THE APPOINTMENT OF THE PAPAL NUNCIO TO POLAND, NOVEMBER 1935 – APRIL 1937SummaryThe article describes the appointment of Filippo Cortesi to the office of papal nuncio to the Republic of Poland, and reviews the role of the Polish diplomats accredited to the Holy See in this process. The appointment of a nuncio following the departure of Francesco Marmaggi was extremely complicated. The list of candidates was the resultant of a number of factors. The individuals whose names were on it had used influence with the pope, the Vatican’s secretary of state, or former nuncios to Warsaw. Both the Polish government and the bishops of Poland had a say in the final outcome. In addition there was also the volatile political situation in Europe at the time, especially in Spain and Yugoslavia, which exerted an effect on the process. In June 1936 Carlo Chiarlo received the nomination for the office. However, the unanimously negative position of the Conference of the Bishops of Poland, especially Cardinals Kakowski and Hlond, stopped the appointment at the last moment. The Polish Government did not want Ermenegildo Pellegrinetti to be appointed and tried to prevent it, considering Angelo Giuseppe Roncalli the ideal candidate. Eventually Pius XI appointed Filippo Cortesi, formerly nuncio to Argentina.

Probing Questions

Cognitive online pretests have, in recent years, become recognized as a promising tool for evaluating questions prior to their use in actual surveys. While existing research has shown that cognitive online pretests produce similar results to face-to-face cognitive interviews with regard to the problems detected and the item revisions suggested, little is known about the ideal design of a cognitive online pretest. This study examines whether the number of open-ended probing questions asked during a cognitive online pretest has an effect on the quality and depth of respondents’ answers as well as on respondents’ satisfaction with the survey. We conducted an experiment in which we varied the number of open-ended probing questions that respondents received during a cognitive online pretest. The questionnaire consisted of 26 survey questions, and respondents received either 13 probing questions ( n = 120, short version) or 21 probing questions ( n = 120, long version). The findings suggest that asking a greater number of open-ended probes in a cognitive online pretest does not undermine the quality of respondents’ answers represented by the response quality indicators: (1) amount of probe nonresponse, (2) number of uninterpretable answers, (3) number of dropouts, (4) number of words, (5) response times, and (6) number and type of themes covered by the probes. Furthermore, the respondents’ satisfaction with the survey is not affected by the number of probes being asked.

Onychomycosis (Tinea unguium) is said to be the most common cosmetological nail fungal infection. Dermatophyte is a type of fungus that causes this condition. Discoloration and thickening of the nail are found to be the common symptoms of all nail diseases. In this scenario, Onychomycosis is considered as one of the cosmetic problems that leads to cellulitis in adults and diabetic patients. Anatomical structure of the nail and disease manifestations made nail disorders as a difficult endeavor. Onychomycosis is chronic and difficult to eradicate. Many oral antifungal agents are available for the treatment of nail infections. The oral and parenteral administration of antifungal agents can elevate the serum hepatic enzyme levels and causes typical hepatocellular injury within a few weeks of therapy. The goal of this review is to study the role of transungal delivery systems (nail patches) as a promising tool for onychomycosis to encounter the clinical conditions of the patient. Longer therapies and technical treatment methods may frustrate the patients. This novel antifungal therapy helps to avoid the surgical removal of nail for onychomycosis patients. Eradication of issues with Onychomycosis can be achieved by an excellent delivery system with deeper drug release and drug retention in the nail cuticle. Patients who are suffered from onychomycosis are facing embarrassment and disfigurement in the society. So, this newer treatment solution can improve the quality of life of patients.1-3
