Danza, lingua e potere: (s)cortesia ne La dodicesima notte di Shakespeare
Authors: Ciambella Fabio 
Published: January 2021

Dance in Elizabethan and Jacobean England was a practice closely linked to the notion of power, understood both from a political point of view – especially in relation to courtly dances – and from a gender perspective – as regards popular dances in particular. The purpose of this article is to conduct a linguistic analysis of Shakespeare’s Twelfth Night 1.3, where two secondary characters, Sir Andrew Aguecheek and Sir Toby Belch, compete for the woman they both love – countess Olivia – by displaying absurd terpsichorean skills. With the support of conversation analysis and cognitive linguistics, this article underlines how the concept of power (intended both as man-man and man-woman relationship) is expressed at the linguistic level with a series of lexical and morphosyntactic strategies in the discourse about Renaissance dances.
Assessing the HIV Knowledge, Awareness, and Utilization of YFS among Undergraduates in Rivers State, Nigeria
Authors: Ofurum Ifeoma Chinyere , Job Nneka Gabriel- 
Published: January 2021

Background: The establishment of a Youth Friendly Centre (YFC) is to ensure that the reproductive and sexual health needs of young people are adequately met. However, data have shown that a number of them are not even aware of such Centres in their vicinities or the services they offer, how much more utilize them. Therefore, this study aimed at assessing the level of HIV knowledge, awareness, and utilization of Youth Friendly Services (YFS) among undergraduates in Rivers State University, Rivers State, Nigeria.
Methods: A total of 520 students were given structured self-administered questionnaire which had been validated and pretested. Four hundred and forty-six questionnaires were returned properly filled. Information regarding knowledge of Human immunodeficiency virus/Acquired immunodeficiency syndrome (HIV/AIDS), awareness, and utilization of Youth Friendly Services were obtained from the students.
Results: Two hundred and nineteen (49.1%) of the students indicated HIV had no cure, while 73(16.4%) reported that there was a cure and 154 (34.5%) specified they were uncertain. The female respondents had a better knowledge compared to their male counterparts. The respondents exhibited a high knowledge of HIV preventive measures with the majority 357 (80%) indicating that abstinence was the best means. All the students agreed that everyone was at risk of HIV if they engaged in risky behaviors. In spite of this good knowledge on HIV, only 112 (25.1%) of the students were aware of a YFCs on campus.
Conclusion: The high knowledge level of HIV exhibited by the students did not translate to the awareness and utilization of the YFS. There is still so much to be done by health workers and the university committee if the students are to be encouraged to use the services offered at the Centre.

Published: January 2021

Background: The most prominent source of anovulatory infertility in the world is polycystic ovary syndrome. Getting pregnant these days has a larger risk of early maternal death than in the general population. It induces symptoms in about five and ten percent of women of reproductive age (12-45 years old). Women that are insulin tolerant are more prone to have Elevated Insulin levels, Polycystic OVARIES and Hyperandrogens. They are at risk for suboptimal reproductive activity attributable to compromising ovarian function and hormonal equilibrium. The aim of this research was to determine the prevalence of late pregnancy failure in women with Polycystic Ovary Syndrome (PCOS) taking metformin as compared to women who don't take it.
Materials and Methods: This case control-controlled study included 100 females and divided in to two groups. Each group composed of 50 patients and the patients were distributed in each group by simple Randomization method.
Results: There was no significant difference between control and study group regarding todescriptive data. Association between rate of pregnancy loss and metformin treatment early pregnancy loss was significantly frequent in control group than in study group with metformin treatment. Gestational age (weeks)at which pregnancy loss occurred is significantly higher in study group than in control group. The rate of early pregnancy loss among studied groups is significantly lower than in control group.
Conclusion: Metformin therapy in pregnant women with polycystic ovary syndrome was associated with a significant reduction in the rate of early pregnancy loss. It was well tolerated by patients with a minimum of side effects. However, extended studies are required to evaluate its effect on further pregnancy complications and fetal outcomes.

Introduction: Fungi are organisms that present themselves in multicellular macroscopic and unicellular microscopic forms. They are eukaryotic, heterotrophic, reproduce asexually/sexually, cosmopolitan, achlorophyllates and are present in various climatic conditions and found in a variety of species and forms in nature.
Aims: Present the emerging evolution of fungi, their underreporting, scale and parameters that show their potential as a heterotrophic organism, decomposer and pathogen.
Methodology: In this review, we conducted a search emphasizing themes about fungi using the available databases and based on the scientific literature, we discussed a series of recent issues involving this wide realm and the constant controversies and expectations that guide the existence of fungi on the planet.
Results: The results presented show an analysis of the action of these eukaryotic organisms and their interaction with other living beings, the constant changes in taxonomy, their pathogenic potential in plants and animals, issues related to the intrinsic resistance of some species to drugs and also the potential biotechnological for which these organisms demonstrate high plasticity.
Conclusion: The expansion of fungal diseases to the fauna and flora of the planet; leads us to believe that, unless measures are taken to reinforce biosafety issues, it will be increasingly necessary to take care of the health conditions of the planet to avoid a global collapse caused by microscopic beings.

Published: January 2021

AbstractFollicular dendritic cell sarcoma (FDCS) is a rare malignant neoplasm, which primarily arises in lymph nodes with occasional cases occurring in extranodal locations. The diagnosis is often challenging particularly on cytology fine needle aspiration due to overlapping morphologic and immunohistochemical features. We present a case of FDCS diagnosed in an otherwise asymptomatic 33‐year old male. The aim of our case report is to highlight the key cytomorphologic features and discuss various differential diagnoses of this unusual entity.
Extreme sensitivity of dye solar cells to UV‐induced degradation

Published: January 2021

AbstractPresent practice to avoid harmful effects of UV light on dye solar cells (DSC) is to use a UV filter. However, we show here that a standard 400 nm UV cutoff filter offers inadequate protection from UV‐induced degradation. DSCs that were exposed to only visible light by LED lamps maintained 100% of their initial efficiency after 3000 hours of exposure, whereas the efficiency of DSCs subjected to full light spectrum (Xenon arc lamp) with an efficient UV filter dropped down to 10% of their initial performance already after 1500 hours. Optical analysis of the UV filter confirmed that the amount of light transmitted below 400 nm was negligible. These observations indicate that (a) DSCs can be very sensitive to even minor amount of UV and (b) eliminating the effects of UV light on DSC stability cannot easily be avoided by a UV filter on top of the cell. A detailed analysis of the degradation mechanisms revealed that the culprit to loss of performance was accelerated loss of charge carriers in the electrolyte of the DSCs—a typical symptom of UV exposure. These results suggest that commonly used stability tests under LED illumination are insufficient in predicting the lifetime of DSCs in outdoor conditions. Instead, for such purpose, we recommend solar cell stability to be tested with a full light spectrum and with a suitable UV filter.

Background and Aims
Liver graft quality is evaluated by visual inspection prior to transplantation, a process highly dependent on the surgeon’s experience. We present an objective, noninvasive, quantitative way of assessing liver quality in real time using Raman spectroscopy, a laser‐based tool for analyzing biomolecular composition.

Approach and Results
A porcine model of donation after circulatory death (DCD) with normothermic regional perfusion (NRP) allowed assessment of liver quality premortem, during warm ischemia (WI) and post‐NRP. Ten percent of circulating blood volume was removed in half of experiments to simulate blood recovery for DCD heart removal. Left median lobe biopsies were obtained before circulatory arrest, after 45 minutes of WI, and after 2 hours of NRP and analyzed using spontaneous Raman spectroscopy, stimulated Raman spectroscopy (SRS), and staining. Measurements were also taken in situ from the porcine liver using a handheld Raman spectrometer at these time points from left median and right lateral lobes. Raman microspectroscopy detected congestion during WI by measurement of the intrinsic Raman signal of hemoglobin in red blood cells (RBCs), eliminating the need for exogenous labels. Critically, this microvascular damage was not observed during WI when 10% of circulating blood was removed before cardiac arrest. Two hours of NRP effectively cleared RBCs from congested livers. Intact RBCs were visualized rapidly at high resolution using SRS. Optical properties of ischemic livers were significantly different from preischemic and post‐NRP livers as measured using a handheld Raman spectrometer.

Conclusions
Raman spectroscopy is an effective tool for detecting microvascular damage which could assist the decision to use marginal livers for transplantation. Reducing the volume of circulating blood before circulatory arrest in DCD may help reduce microvascular damage.

Published: January 2021

AbstractIntroductionUnequal access to required health care services could deteriorate inequality in health outcomes and increase mortality and morbidity, especially among disadvantaged groups. One of the most debated factors in shaping health care inequalities is gender. This study aimed to measure and explains gendered socioeconomic‐related inequality in outpatient health care utilization in Iran.MethodsThis is a cross‐sectional research conducted at a national level in Iran. The required data was obtained from an Iranian health care utilization household survey conducted in 2015. Erreygers Concentration Index (ECI) was used to measure the socioeconomic inequality in outpatient health care utilization. A regression‐based decomposition analysis was also used to explain socioeconomic‐related inequalities.ResultsThere was a significant pro‐rich inequality in outpatient health care utilization between males (ECI = 0.115, SE = 0.014) and females (ECI = 0.083 SE = 0.011) indicating that utilization of these services was concentrated on the better‐offs. The decomposition analysis revealed that economic status (males = 50.58%, females = 37.42%) was the main contributor to the observed inequality. Location of residence, health insurance and education were other main driver of these inequalities.ConclusionsDifferent factors have different contribution to socioeconomic‐related inequality in utilization of outpatient health care services and these could be diversified considering gender. Hence, it seems that policy makers could be able to address these inequalities effectively through gender‐oriented policies.
A cross‐linguistic study of multisensory perceptual narrowing in German and Swedish infants during the first year of life
Authors: Dorn Katharina , Cauvet Elodie , Weinert Sabine 
Published: January 2021

AbstractFour‐and‐a‐half‐month‐olds look longer at silent mouth movements corresponding to a language they previously listened to. The perceptual narrowing hypothesis suggests this general ability to decline as a consequence of experience with the infant's native language. We tracked eye‐gaze of German and Swedish infants longitudinally in an intersensory matching procedure at 4.5 and 6 months of age. Infants watched and listened sequentially to side‐by‐side presentations of visual and corresponding auditory fluent speech in their respective native or the non‐native language. Looking times indicated that 4.5‐month‐old infants preferred the respective language they previously listened to, either native or non‐native. However, at 6 months of age they only audio‐visually matched their native language and kept looking at chance level after listening to the non‐native language – suggesting that the intersensory perception of languages narrows down before 6 months of age even in same‐rhythm‐class languages. Intriguingly, the 6‐month‐old German and Swedish samples showed different patterns of preference after listening to their native language. Whereas the German infants looked significantly longer to the German visual speech, the Swedish infants looked significantly shorter to the Swedish visual speech. Different explanations and practical implications for early hearing aids are discussed within the frame of perceptual narrowing.Highlights
First study to examine perceptual narrowing in same‐rhythm‐class languages.
In an intersensory matching procedure audio‐visual matching of languages narrows down before 6 months of age in same‐rhythm‐class languages.
The empirical findings might have crucial practical implications for early hearing aids.
Scope and correlates of high school youths' exposure to dating and sexual violence prevention initiatives
Authors: Edwards Katie M. , Banyard Victoria L. , Rizzo Andrew , Greenberg Patricia 
Published: January 2021

AbstractThe researchers examined the extent to which high school youth were exposed to dating and sexual violence (DSV) prevention types (e.g., social marketing campaign) across various locations (e.g., in‐school) and how exposure to DSV prevention related to perceptions of social norms and collective efficacy. Participants included 877 high school youth who completed in‐school surveys across three towns in New England. Most youth (92%) were exposed to DSV prevention. In general, active exposure and active participation, more so than passive exposure, were related to greater perceptions of collective efficacy and perceptions of social norms more intolerant of DSV. Results also suggested that online exposure to DSV prevention was the most consistent correlate of greater perceptions of collective efficacy and perceptions of social norms more intolerant of DSV. These findings provide clues about the types and locations that might be most effective at preventing DSV among youth.

Published: January 2021

AbstractRecently, different nanocrystals have been reported to be the alternative, optimistic, and novel antimicrobial agent against the many antibiotic‐resistant bacteria. Here, ligand‐free CdS and Ag‐doped CdS (Ag/CdS) nanocrystals have been synthesized by chemical methods for the study of the antimicrobial activity on Escherichia coli and Staphylococcus aureus by Kirby–Bauer diffusion method to see the effect against Gram‐positive and Gram‐negative bacteria. These prepared nanocrystals have been characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), and X‐ray diffraction (XRD). TEM and SEM images confirm the spherical morphology of both the sample and the respective XRD patterns indicate polycrystalline nature having a cubic zinc blende structure. Antibacterial activities have been tested with CdS and Ag/CdS, considering concentrations ranging from 10 to 200 μg/ml. After 24 h of incubation, the zone of inhibition (ZOI) is measured for each concentration, which shows that both the nanocrystals are ineffective against E. coli but much effective against S. aureus at this low concentration range. Furthermore, Ag/CdS nanocrystals have been found to show much more ZOI than CdS. Differences in the antibacterial activity can be due to the presence of different cell wall in E. coli and S. aureus.

Published: January 2021

AbstractImplementing two‐way strategies to enhance the lipid production in Rhodotorula mucilaginosa with the help of metabolic engineering was focused on the overexpression of acetyl coenzyme A carboxylase (ACC1 carboxylase) gene and repression of 3‐hydroxy 3‐methylglutaryl reductase (HMG‐CoA reductase). Using an inducer (sodium citrate) and inhibitor (rosuvastatin), the amounts of biomass, lipid, and carotenoid were estimated. In the presence of inhibitor (200 mM), 62% higher lipid concentration was observed, while 44% enhancement was recorded when inducer (3 mM) was used. A combination of both inhibitor and inducer resulted in a 57% increase in lipid concentration by the oleaginous yeast. These results were again confirmed by real‐time polymerase chain reaction by targeting the expression of the genes coding for ACC1 carboxylase and 13‐fold increase was recorded in the presence of inducer as compared with control. This combined strategy (inducer and inhibitor use) has been reported for the first time as far as the best of our knowledge. The metabolic engineering strategies reported here will be a powerful approach for the enhanced commercial production of lipids.
