Published: July 2021

A rigorous mathematical model was developed for a complex
liquid-liquid-solid system in a batch reactor. The approach is general
but particularly well applicable for the indirect epoxidation of
vegetable oils according to the concept of N. Prileschajew. The model
considers intra- and interfacial mass transfer effects coupled to the
reaction kinetics. The liquid phases were described with chemical
approach (aqueous phase) and a reaction-diffusion approach (oil phase).
The oil droplets were treated as rigid spheres, in which the overall
reaction rate is influenced by chemical reactions and molecular
diffusion phenomena. The model was tested with a generic example, where
two reactions proceeded simultaneously in the aqueous and oil phases.
The example (i.e. fatty acid epoxidation à la Prileschajew) illustrated
the power of the real multiphase model in epoxidation processes. The
proposed modelling concept can be used for optimization purposes for
many applications, which comprise a complex water-oil-solid catalyst
system.

Background Vaccines that incorporate multiple SARS-CoV-2
antigens can further broaden the breadth of virus-specific cellular and
humoral immunity. This study describes the development and
immunogenicity of SARS-CoV-2 VLP vaccine that incorporates the 4
structural proteins of SARS-CoV-2. Methods VLPs were generated
in transiently transfected HEK293 cells, purified by multimodal
chromatography and characterized by tunable resistive pulse sensing,
AFM, SEM, and TEM. Immunoblotting studies verified the protein
identities of VLPs. Cellular and humoral immune responses of immunized
animals demonstrated the immune potency of the formulated VLP vaccine.
Results Transiently transfected HEK293 cells reproducibly
generated vesicular VLPs that were similar in size to and expressing all
four structural proteins of SARS-CoV-2. Alum adsorbed, K3-CpG ODN
adjuvanted VLPs elicited high titer anti-S, anti-RBD, anti-N IgG,
triggered multifunctional Th1 biased T cell responses, reduced virus
load and prevented lung pathology upon live virus challenge in
vaccinated animals. Conclusion These data suggest that VLPs
expressing all four structural protein antigens of SARS-CoV-2 are
immunogenic and can protect animals from developing COVID-19 infection
following vaccination.
Brucellosis Reemergence after a Decade of Quiescence in Palestine, 2015-2017: a Seroprevalence and Molecular Characterization Study
Authors: Ashhab Yaqoub , Aljanazreh Bessan , Alzatari Khaled , Tamimi Asmaa , Alsaafeen Mohammad , Hassouneh Waheed
Published: July 2021

Brucellosis is an endemic disease in many developing countries and
ranked by the World Health Organization among the top seven “neglected
zoonoses”. Although a Palestinian brucellosis control program was
launched in 1998, the disease reemerged after 2012. Interestingly, a
similar reemerging pattern was reported in the neighboring Israeli
regions. The aim of this work was to characterize the reemerging strains
and delineate their genetic relatedness. During 2015-2017, blood samples
from 1324 suspected patients were analyzed using two serological tests.
Seropositive samples were cultured, and their DNAs were analyzed by
different genetic markers to determine the involved Brucella
species and rule out any possible involvement of the Rev.1 vaccine
strain. The rpoB gene was sequenced from 9 isolates to screen for
rifampicin resistance mutations. Multi Locus VNTR Analysis (MLVA-16) was
used for genotyping the isolates. The molecular analysis showed that all
isolates were B. melitensis strains unrelated to the Rev.1
vaccine. The rpoB gene sequences showed four single nucleotide
variations (SNVs) not associated with rifampicin resistance. MLVA-16
analysis clustered the isolates into 22 unique genotypes that belong to
the East Mediterranean lineage. Altogether, our findings show that the
reemergence of brucellosis was due to B. melitensis strains of
local origin, the Palestinian and Israeli control programs’ weaknesses
could be a major factor behind the reemergence of the disease. However,
other socioeconomic and environmental factors must be investigated.
Moreover, strengthening brucellosis control programs and enhancing
cooperation between all stakeholders is essential to ensure long-term
program outcomes to fight brucellosis.

We investigated responses of tomato to two functional guilds of
nematodes - plant parasite (Meloidogyne javanica) and entomopathogens
(Heterorhabditis bacteriophora, Steinernema feltiae belowground, and S.
carpocapsae) - as well as a leaf mining insect (Tuta absoluta)
aboveground. Our results indicate that entomopathogenic nematodes
(EPNs): 1) induced plant defense responses, 2) reduced root knot
nematode (RKN) infestation belowground and 3) reduced herbivore (T.
absoluta) host preference and performance aboveground. Concurrently, we
investigated the plant signaling mechanisms underlying these
interactions using biochemical and transcriptome analyses. We found that
both entomopathogen and parasite triggered immune responses in plant
roots with shared gene expression. Tomato plants responded similarly to
presence of RKN or EPN in the root zone, by rapidly activating
polyphenol oxidase (PPO) and guaiacol peroxidase (GP) activity in roots,
but simultaneously suppressed this activity in aboveground tissues. We
quantified changes in gene expression in tomato that may play essential
roles in defense response to RKN, which were also coincidentally
triggered by EPN. Overall, EPN inoculation directly mediated enhanced
plant defense and reduced subsequent RKN infection. Likewise, we show
that EPNs modulate plant defense against RKN invasion. Inoculation of
tomato roots with EPNs belowground reduced both host preference and
performance of the aboveground herbivore, T. absoluta. Inoculations of
roots with EPN also triggered an immune response in tomato which could
explain an observed decrease in egg laying and developmental performance
exhibited by herbivores on EPN-inoculated plants. Our results support
the hypothesis that subterranean EPNs activate a battery of plant
defenses associated with systemic acquired resistance (SAR) and/or
induced systemic resistance (ISR) with antagonistic effects on
temporally co-occurring subterranean plant pathogenic nematodes a
Large paracetamol overdose -- higher dose NAC is required
Authors: Bateman D
Published: July 2021

Paracetamol poisoning continues to be a worldwide problem and despite
the availability of an affective antidote, N-acetylcysteine (NAC), the
optimal way to use this antidote, particularly following very large
doses of paracetamol, has not been established. Recent case series have
shown an increased toxicity from paracetamol, even in those receiving
prompt NAC therapy, at high doses of paracetamol, particularly in
patients above the 300 mg/L nomogram treatment line. Clinical trial
evidence supporting shorter NAC dosing now allows the possibility for
intensifying treatment without the risk of very high rates of ADRs. New
biomarkers also show the possibility of early identification of patients
at risk of liver injury who might also benefit from increased intensity
treatment. This article discusses these data and proposes a logical
therapy for increasing NAC dosing which now requires clinical trial
testing.
Wherefore “plug-and-chug”?: computer algebra versus A-level mathematics
Authors: Bibby Neil
Published: July 2021

The development in recent years of software systems (“computer algebra” systems, or “symbolic manipulators”) which, in effect, automate large areas of mathematics presents an immediate and huge challenge to mathematics education, especially at A-level. For many students current practice in A-level mathematics seems largely to consist of the assimilation, rehearsal and implementation in stereotyped contexts of a more-or-less well-defined set of standard algorithms in short, “plug-and-chug” mathematics, as Philip Davis has described it. With the aid of computer algebra systems demonstrations of “A-level papers in ten minutes” have recently been possible, and this clearly illustrates the essentially “plug-and-chug” nature of the assessment tasks.

OBJECTIVE

To examine longitudinal
and dose-dependent associations of dietary glycemic index (GI), glycemic load
(GL), and fiber with body weight and glycemic status during 3-year weight-loss
maintenance (WLM) in high-risk adults.

RESEARCH DESIGN AND METHODS

This secondary analysis used pooled data
from the PREVIEW randomized controlled trial, which was designed to test the
effects of four diet and physical activity interventions. 1,279 participants
with overweight or obesity (aged 25–70 years; BMI≥25 kg·m-2) and
pre-diabetes at baseline were included. Multi-adjusted
linear mixed models with repeated measurements were
used to assess longitudinal and dose-dependent associations, by merging the
participants into one group and dividing them into GI, GL, and fiber tertiles,
respectively.

RESULTS

In the available-case and complete-case
analyses, each 10-unit increment in GI was associated with a greater
regain of weight (0.46 kg·year-1; 95% CI 0.23, 0.68; P<0.001)
and increase in HbA1c. Each 20-unit increment in GL was associated
with a greater regain of weight (0.49 kg·year-1; 0.24, 0.75; P<0.001)
and increase in HbA1c. The associations of GI and GL with HbA1c
were independent of weight change. Compared with those in the lowest tertiles,
participants in the highest GI and GL tertiles had significantly higher weight
regain and increases in HbA1c. Fiber was inversely associated with
increases in waist circumference, but the associations with weight regain and
glycemic status did not remain robust in different analyses.

CONCLUSIONS

Dietary
GI and GL were positively associated with weight regain and deteriorating
glycemic status. Stronger evidence on the role of fiber is needed.

Published: July 2021

Objective: The metabolic phenotype of youth-onset type 2
diabetes (T2D) differs from that of adult-onset T2D, but little is known about
genetic contributions. We aimed to evaluate the association between a T2D
genetic risk score (GRS) and traits related to glucose-insulin homeostasis among
healthy youth. Research Design and Methods: We used data from 356 youth (mean age 16.7 years, 50%
female) in the EPOCH cohort to calculate a standardized weighted GRS based on
271 single nucleotide
polymorphisms (SNPs) associated with T2D in adults. We used linear regression to assess
associations of the GRS with log-transformed fasting glucose, 2-hour glucose, homeostasis
model of insulin resistance
(HOMA-IR), oral disposition index, and insulinogenic index adjusted for age,
sex, body mass index (BMI) z-score, in utero exposure to maternal
diabetes, and genetic principal components. We also evaluated effect
modification by BMI z-score, in utero exposure to maternal diabetes and
ethnicity. Results: Higher weighted GRS was associated with lower oral disposition index (b=-0.11; 95% CI: -0.19, -0.02) and insulinogenic index (b=-0.08; 95% CI: -0.17, -0.001), but not with fasting
glucose (b=0.01; 95% CI: -0.01, 0.02), 2-hour glucose
(b=0.03; 95% CI: -0.0004, 0.06), or HOMA-IR
(b=0.02; 95% CI: -0.04, 0.07). BMI
z-score and in utero exposure to maternal diabetes increased the effect
of the GRS on glucose levels. Conclusions: Our results suggest that T2D genetic risk factors
established in adults are relevant to glucose-insulin homeostasis in youth and that maintaining a
healthy weight may be particularly important for youth with high genetic risk
for T2D.

Introduction. Currently, the purification of wastewater and technological solutions by membrane methods is considered a promising way to neutralize liquid waste. Therefore, the task of developing an engineering method for calculating baromembrane devices is a challenge. Studies on methods involving calculation of design and process variables, membrane equipment design, research of technological features of membrane devices, selection of design schemes, as well as methods of strength and rigidity analysis, are investigated.

Materials and Methods. Basic elements of the body of the combined membrane apparatus are considered, a design scheme is proposed, and a method for calculating the strength and rigidity of the main load-bearing element, the cover, is described.

Results. The methods determine the required dimensions of shells and plates for the development of a combined membrane apparatus, and evaluate the strength properties of the devices of this class. The construction elements of the apparatus (primarily, the load-bearing covers) must meet not only the requirements of efficiency and quality of separation and cleaning of solutions, but also the conditions for safe operation. Therefore, the design of the device covers should be based on the optimal design dimensions (thicknesses of round plates, toroidal shells, and support rings). To test the method, the stress-strain state of the membrane apparatus structure was calculated for strength and rigidity. As an example, we consider one cover presented in the form of an open toroidal shell. The evaluation of the application of this technique, taking into account the fact that the shell is mated with a round plate in the inner diameter, and with a ring in the outer diameter, has provided the determination of the required parameters.

Discussion and Conclusions. The obtained method of analytical description of the mechanical impact on the elements of the combined apparatus and the example of calculating the toroidal shell and plate, enables to evaluate the stressstrain state of the structure for strength and rigidity. The results of the calculation of covers made of various materials at different pressures are presented. Loading the combined apparatus with transmembrane pressure made it possible to determine the required dimensions of the shells and plates for its design and development.

One of the factors that can influence an individual to start a new business is the perception of danger and uncertainty. The COVID-19 pandemic and the COVID-19 protocols have left so many people with diverse perceptions of danger and uncertainties. In addition, the pandemic brought about an unprecedented increase in the use of social media sites. Therefore, this study investigates if Nigerian undergraduate students’ COVID-19 perception and social media site use influences them to engage in pre-start-up and start-up activities. The adopted study design is qualitative method that is based on Focus Group Interview (FGI). The study data were collected from final year students in 10 public Universities in South Eastern Nigeria. It was found from the thematic content analysis that despite the challenges posed by the COVID-19 pandemic and the COVID-19 rules, the undergraduate students were involved in pre-start-up and start-up activities owing to their positive perceptions of the COVID-19 rules and the use of social media sites. However, their start-up activities are constrained by lack of business capital. The researchers recommend the establishment of entrepreneurship development fund for undergraduate students. Qualitative and/or quantitative methods should be adopted to replicate this study in similar or different higher institutions in other parts of the world.
