Authors: El-ASSAL MONA IBRAHIM , SAMUEL DALIA
Published: January 2022

Objective: In an attempt to optimize the anti-Alzheimer effect, rivastigmine-loaded chitosan nanoparticles were developed in order to target of brain through skin permeation.
Methods: Rivastigmine-loaded chitosan-tripolyphosphate nanoparticles were prepared by modified ionic gelation method using tween 80 surfactants in different batches with variable chitosan/cross-linker ratios, desirability factors were applied to choose the optimal Nanocarrier and (F15) was selected. Different rivastigmine concentrations were loaded and the highest encapsulation efficiency formulae chosen for further study and evaluated by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and differential scanning calorimetric (DSC). Further, drug loading, Ex-vivo skin permeation of Nano-gel, and kinetic studies were carried out in addition to stability along three months under different temperature.
Results: Particle size and polydispersity index showed average 291.6±7.70 to 490.6±7.42 d. nm. and 0.333±0.04 to 0.570±0.023 respectively. The nanoparticles were spherical in shape. Drug concentrations 4% w/w showed the highest drug entrapment efficiency (89.80%) and drug loading (40.81). Ex vivo studies shows that gel formulae of rivastigmine loaded chitosan nanoparticles was not irritant to rat skin had better skin permeation than chitosan nanoparticles aqueous dispersion also capable of releasing the drug in a sustained manner, and follow kinetic diffusion model. Optimum formula F15 was physical and chemical stable.
Conclusion: The experimental results showed the suitability of chitosan nanoparticles coated with a surfactant as a potential carrier for permeation through skin and brain, providing sustained delivery of rivastigmine.

Published: January 2022

Objective: The present research work of Amphotericin B Proniosomal gel focuses on improving patient compliance by reducing the side effects of conventional intravenous injections and minimizing the problem of physical stability and to localize drug at site of action.
Methods: Proniosomal gels are prepared by coacervation phase separation technique using different concentration of non-ionic surfactants (Span and Tween) for uniform vesicle formation, lecithin as permeation enhancer/membrane stabilizer and cholesterol as a vesicle cement providing prolonged release. Prepared gels were evaluated for their viscosity, pH, spreadability, entrapment efficiency, drug content uniformity, extrudability, in vitro drug release, permeability and stability studies.
Results: Among the nine formulations, F2 (containing 10 mg drug, 250 mg Span 60, 50 mg Soya lecithin) was found to be promising. Fourier Transform infra-red (FT-IR) spectra studies represented no interaction and physicochemical characteristics were found within the limits. The percentages of drug content and entrapment efficiency were determined to be 95.16%±0.40 and 94.20%±0.20, respectively. In vitro drug release was about 95.72%±0.30.
Conclusion: Proniosomal gel could constitute a promising approach for topical delivery of Amphotericin B by encapsulating it in non-ionic surfactant to provide patient compliance with cutaneous fungal infection, which was found to be safe, tolerable and efficacious.

In addition, the increase in Covid-19 cases also moderated the relationship between the rupiah exchange rate and the stock price.
Pengaruh Corporate Social Responsibility (CSR) Dan Good Corporate Governance (GCG) Terhadap Tax Avoidance
Authors: Setyawan Setu
Published: January 2022

This study aims to test the influence of corporate social responsibility (CSR) and good corporate governance (GCG) on tax avoidance. The population in this study was a CGPI-winning company registered with IICG in 2018. The samples selected for use in the study were 15 companies that met the sample criteria. The study was analyzed using partial last square analysis (PLS). The results showed that CSR has a negative influence on tax avoidance. The higher the csr disclosure rate made by the company, the lower the value of CETR which means the level of tax avoidance is high. Meanwhile, good corporate governance has a significant positive influence on tax avoidance. This shows that good corporate governance then corporate tax avoidance will decrease, and the company will be able to run its business in accordance with applicable business regulations including fiscal regulations. This research is potentially relevant to academia, and management. This research provides empirical insight into two major concepts: agency and stakeholder theory issues in tax avoidance schemes.

Relationship between forest biodiversity attributes and potential carbon stocks in dry tropical reserve forests of Assam, northeast India
Authors: Malunguja Gisandu K. , Thakur Bijay , Devi Ashalata
Published: January 2022

Potential forest carbon stocks are significantly correlated to forest biodiversity attributes such as diversity, density, and richness. However, there is little such information on dry tropical reserve forests of Assam, a state in northeast India. We studied this relationship in two reserve forests. Pearson correlation, cluster analysis, and regression analysis were used to explore these relationships. The estimation of plant carbon stocks was made using both destructive methods for herbaceous and non-destructive allometric methods for trees. The most dominant plant species in the Bhomoraguri reserve forest were Cynodon dactylon, Datura stramonium, Clitoria ternatea, and Tectona grandis for grasses, forbs, climbers, and trees, respectively. Cymbopogon nardus, Colocasia esculenta, Mikania micrantha, and Shorea robusta, were dominant species in the Balipara reserve forest for grasses, forbs, climbers, and trees, respectively. The presence of Lantana camara, Smilax ovalifolia and Piper betle in the studied forests suggests disturbed ecosystems. Other observed species such as Aristida spp., Cenchrus spp., Ipomoea cheirophylla, and Sida spp. are indicators of disturbed ecosystems as well. The biomass stock differed significantly among plant growth forms. Carbon stocks were 302.93 and 283.97 t ha–1 in the Bhomoraguri reserve forest and Balipara reserve forest, which were equivalent with 555.87 and 521.30 t ha–1 of CO2 sequestration, respectively. Tree species contributed the greatest amount (54.80%), followed by forbs (21.36%), climbers (19.35%), and least for grasses (4.49%). Correlation analysis indicated a strong positive relationship between the density of trees and climber species with carbon stock potentials, suggesting that increase of their density favoured carbon sequestration in forest ecosystems. Diversity of grasses was negatively correlated with potential carbon stock in the examined forests. The unique contribution of each group to carbon stock was 91.8, 58.01, 51.3, and 11.11% for climbers, trees, grasses, and forbs, respectively. Thus, it is important to examine biodiversity attributes in estimation of forest carbon stocks.
Soil chemical properties and mineral nutrition of Latvian accessions of Trifolium fragiferum, a crop wild relative plant species

Published: January 2022

The aim of the present study was to compare soil chemical composition and aspects of mineral nutrition of several accessions from different geographically isolated sites in Latvia of Trifolium fragiferum L., a crop wild relative plant species. Eight geographically isolated micropopulations of T. fragiferum in Latvia were identified, and material was sampled for analysis of plant-available mineral nutrient concentrations in soil and mineral nutrient concentrations in leaf tissues. Micropopulations of T. fragiferum were associated with rivers, lakes and the sea, thus also outside typical coastal or inland-located salt-affected grassland habitats. Soil concentration of plant-available mineral nutrients showed significant variation between different sites, ranging from 59% for N to 193% for Ca. Variation in mineral element concentration in plant leaf tissues was relatively lower. Multivariate analysis showed that sites with similar localization on river shores or in coastal areas had similar characteristics, as these were grouped together according to both soil mineral nutrient availability as well as leaf tissue mineral element concentrations. T. fragiferum can be characterized as a species able to maintain mineral homeostasis in leaf tissues irrespective of large variability in soil plant-available mineral nutrient concentrations and different levels of soil pH. Together with general resilience to environmental constraints, this allows to predict a relatively good conservation status of T. fragiferum in Latvia in spite of rather limited number and size of the geographically isolated micropopulations.

Durable results of preserved valve and root after acute type A aortic dissection surgery in bicuspid aortic valve
Authors: Hsu Tsu-Jui , Chen Cheng-Wei , Hsu Ron-Bin
Published: January 2022

Background and aims of the study. Data on emergency surgery for
acute type A aortic dissection in patients with bicuspid aortic valve
were limited. Long-term results on the fate of the preserved bicuspid
valve and aortic root were even rare. We sought to assess the clinical
outcome of emergency acute type A aortic dissection surgery in patients
with bicuspid aortic valve. Methods. From 2004 to 2021, 121
patients underwent emergency surgery for acute type A aortic dissection
using a conservative aortic resection. Hospital and late outcomes were
assessed in patients with bicuspid aortic valve. Results. Eight
patients (6.6%) had bicuspid aortic valve with 6 males (75%) and
median age of 49.5 years (range, 34 to 71). Four (50%) had significant
aortic valve dysfunction. Operation included ascending aortic grafting
with aortic valve preservation in 4, ascending aortic grafting with
aortic valve replacement in 3 and ascending aortic grafting with Bentall
root replacement in 1. Hospital mortality rate was 12.5% (1/8). With a
median follow-up of 14.4 years, there was one late death and no proximal
reoperation of 6 preserved roots and 3 preserved valves. Median diameter
of preserved aortic roots changed from 42 (range, 33-43) to 38.5 mm
(range, 35-46) with the average time of 11 years after surgery.
Conclusions. Acute type A aortic dissection in bicuspid aortic
valve was not associated with worse outcome. Aortic valve replacement
was often required. Simultaneous root replacement was not always
necessary. Preservation of normally functioning bicuspid valve and
non-dilated root showed durable long-term results.

Authors: Rehmanji Mohammed , Nesamma Asha , Khan Nida , Fatma Tasneem , Jutur Pannaga
Published: January 2022

Phaeodactylum tricornutum is a marine diatom, and well-studied model of
unicellular microalga. This diatom contains a wide range of high-value
renewables (HVRs) with high commercial relevance owing to their
importance in human nutrition and health. In this study, we screened P.
tricornutum for biomass, eicosapentaenoic acid (EPA) and fucoxanthin
production under photoautotrophic and mixotrophic condition with various
substrate combinations. Results highlights that culture supplemented
with glycerol and urea lead to enhanced biomass, biochemical and HVR
production. Further continuous feeding of urea in glycerol supplemented
medium results in an increase in biomass yield (0.77 g L-1) by
~ 2-fold. Additionally, continuous feeding of urea
channelizes the carbon flux towards biosynthesis of fatty acids
increasing FAME content by ~2-fold as compared to the
control conditions. Overall EPA and fucoxanthin production was 27 mg L-1
and 11 mg L-1 (~2 & 4 fold) in urea fed cultures
respectively. Present study demonstrates efficient valorization of
cost-effective substrates such as glycerol and urea for the production
of high-value renewables in P. tricornutum.

Гиперболоид инженера Вальса: Набоков и советская фантастика 1910-х – 1920-х гг. [Engineer Waltz’s Hyperboloid: Vladimir Nabokov and the Soviet Fantastic Literature of the 1910—1920s]
Authors: Polishchuk Vera
Published: January 2022

The article is aimed to trace some significant parallels between Nabokov’s Russian prose and drama, and a number of Soviet fantastical novels. A close reading reveals a whole network of allusions to Alexander Grin’s The Glittering World (Blistaiushchii mir, 1924) in Invitation to a Beheading (Priglashenie na kazn’, 1935—36), including the usage of the Romantic hero model, canonic female figures and gnostical imagery, originating from The Invisible Man by H. G. Wells. As for The Waltz Invention (Izobretenie Val’sa, 1938), the tragicomedy gives us compelling evidence that Nabokov deliberately wrote a parody on The Garin Death Ray (Giperboloid inzhenera Garina, 1926—27), a famous Soviet sci-fi novel by Alexey Tolstoy. In general, it can be said that Nabokov is scrupulously using implicit allusions and sophisticated wordplay on every level of his texts, widening the genre boundaries of science fiction, dystopia and adventure novel to invent a new literary strategy and new genres of his own. KEYWORDS: 20th-Century Russian Literature, Vladimir Nabokov (1899—1977), Priglashenie na kazn’ (1935—36), Izobretenie Val’sa (1938), Alexander Grin (1880—1932), Alexey Tolstoy (1883—1945), Allusion, History of Literature.
Из материалов для комментария к «Капитанской дочке»: 9–11 [Notes and Queries on _The Captain’s Daughter_ (9–11)]
Authors: Ospovat Alexander
Published: January 2022

There are three sections in this article, all concerning The Captains Daughter (Kapitanskaia dochka, 1836) by Alexander Pushkin. The first section reconstructs the hidden yet crucial train of thought launched by the elder Grinev’s reading of The Court Almanach for 1772, which comes to drive the novel’s plot in a surprising direction. The second section investigates the protagonist’s failed military career. The third section discusses Pushkin’s linguistic lapse (na son griadushchii instead of na son griadushchim), a distortion of a liturgical phrase well known to Orthodox Christians. Keywords: 19th-Century Russian Literature, Alexander Pushkin (1799—1837), Kapitanskaia dochka (1836), Russo-Turkish Wars (1736—1739, 1768—1774), Military Careers, The Orthodox Prayer Book, In memoriam: Larisa Georgievna Stepanova (1941—2009).
Surgeons’ non-transparent facemasks challenge the physician–patient relationship in the orthopedic outpatient clinic of a tertiary university hospital during the COVID-19 pandemic: a prospective cohort study of 285 patients
Authors: Schneider Kristian Nikolaus , Theil Christoph , Gosheger Georg , Lampe Lukas Peter , Rödl Robert , Mellmann Alexander , Kampmeier Stefanie , Rickert Carolin
Published: January 2022

Background and purpose — Facemasks play a role in preventing the respiratory spread of SARS-CoV-2, but their impact on the physician–patient relationship in the orthopedic outpatient clinic is unclear. We investigated whether the type of surgeons’ facemask impacts patients’ perception of the physician–patient relationship, influences their understanding of what the surgeon said, or affects their perceived empathy.
Patients and methods — All patients with an appointment in the orthopedic outpatient clinic of a tertiary university hospital during the 2-week study period were included. During consultations, all surgeons wore a non-transparent (first study week) or transparent facemask (second study week). Results of 285 of 407 eligible patients were available for analysis. The doctor–patient relationship was evaluated using the standardized Patient Reactions Assessment (PRA) and a 10-point Likert-scale questionnaire ranging from 0 (strongly disagree) to 10 (strongly agree).
Results — A non-transparent facemask led to more restrictions in the physician–patient communication and a worse understanding of what the surgeon said. Patients’ understanding improved with a transparent facemask with greatest improvements reported by patients aged 65 years and older (non-transparent: 6 [IQR 5–10] vs. transparent: 10 [IQR 9–10], p < 0.001) and by patients with a self-reported hearing impairment (non-transparent: 7 [IQR 3–7] vs. transparent: 9 [IQR 9–10], p < 0.001). The median PRA score was higher when surgeons wore a transparent facemask (p= 0.003).
Interpretation — Surgeons’ non-transparent facemasks pose a new communication barrier that can negatively affect the physician–patient relationship. While emotional factors like affectivity and empathy seem to be less affected overall, the physician–patient communication and patients’ understanding of what the surgeon said seem to be negatively affected.
Does the Bleaching Gel Application Site Interfere With the Whitening Result? A Randomized Clinical Trial

Published: January 2022

This study aimed to evaluate the effect of the bleaching gel application site on chromatic changes and postoperative sensitivity in teeth. Thirty patients were selected and allocated to three groups (n=10 per group), according to the location of the gel: GI, cervical application; GII, incisal application; and GIII, total facial. The amount and time of application of the 35% hydrogen peroxide (H2O2) gel were standardized. Color changes were analyzed by ΔE and Wid (bleaching index), using the values obtained in the readings conducted on a digital spectrophotometer in the cervical (CRs) and incisal regions (IRs) of the teeth. Spontaneous sensitivity was assessed using the questionnaire, and the stimulated sensitivity caused by the thermosensory analysis (TSA). The analysis occurred in five stages: baseline, after the first, second, and third whitening sessions (S), and 14 days after the end of the whitening, using the linear regression statistical model with mixed effects and post-test by orthogonal contrasts (p<0.05). Although the IR was momentarily favored, at the end of the treatment, the restriction of the application site provided results similar to those obtained when the gel was applied over the entire facial surface. Regarding sensitivity, only the GI showed spontaneous sensitivity. In the TSA, GIII had less influence on the threshold of the thermal sensation. It was concluded that the chromatic alteration does not depend on the gel application site. Spontaneous sensitivity is greater when the gel is concentrated in the cervical region (CR), and the teeth remain sensitized by thermal stimuli even after 14 days.

Authors: Zhang CY , Agingu C , Yang H , Cheng H , Yu H
Published: January 2022

Objectives

This study aimed to investigate the effects of hydrothermal treatment on four types of monolithic, translucent, yttria-stabilized, tetragonal zirconia polycrystals (Y-TZPs).

Methods and Materials

Two commercially available Y-TZP brands—SuperfectZir High Translucency (Aidite Technology Co, China) and Katana HT (Kuraray Noritake Dental, Japan) were assessed. For each brand of Y-TZP, materials of four coloring types, including noncolored (NC), colored by staining (CS), precolored (PC), and multilayered (ML) specimens were investigated after hydrothermal aging in an autoclave at 134°C/0.2 MPa for 0 (control group), 5, 10, and 20 hours. The tetragonal-to-monoclinic phase transformation, surface roughness, flexural strength, and structural reliability (Weibull analysis) were measured and statistically analyzed (α=0.05). The subsurface microstructure was analyzed with scanning electron microscopy.

Results

The group ML exhibited the lowest flexural strength and Weibull characteristic strength among the four coloring types (p<0.05). Slight increases in the monoclinic phase volume, flexural strength, and Weibull characteristic strength were observed after hydrothermal aging (pall<0.05). Regardless of coloring type, no significant effects of aging on the Weibull modulus or surface roughness were found for the tested materials. Compared with the Katana HT cross-sections, the SuperfectZir High Translucency cross-sections exhibited a similar but thicker transformation zone.

Conclusions

The coloring procedure and material type were found to affect the mechanical properties and aging resistance of translucent monolithic Y-TZP ceramics. Regardless of the aging time, the surface roughness of the tested Y-TZP ceramics remained unchanged.
