Authors: Viana Ana , Pappis Cristiane , Garcia Viviane , Hoffmann Dylan , Burg Arthur , Dressler Valderi
Published: November 2023

This study deals with a method for Hg determination in multivitamin supplements. Mercury was extracted with L-cysteine prior to its determination using flow injection-cold vapor generationinductively coupled plasma-mass spectrometry. A miniaturized flow injection system was employed for Hg vapor generation and its introduction in the plasma whereas 1% (v v-1) HCl and 0.005% (m v-1) NaBH4 were used for that purpose. Mercury extraction was carried out using 6 mL of 1% m v-1 L-cysteine and 50 mg of sample. Accuracy was proved by comparing the Hg concentration found using L-cysteine with the Hg concentration found in the sample decomposed using microwave-assisted digestion, and analysis of certified soil. The limits of detection and quantification of the proposed method were 2 and 6 ng g-1 of Hg, respectively. The relative standard deviation was < 10% (n = 5). Five samples of multivitamin supplements were analyzed and, in any sample, the tolerable amount of Hg (4.0 µg kg-1 body weight) recommended by the World Health Organization was exceeded. The proposed method for Hg determination meets the current legislation and is feasible for Hg monitoring in multivitamin supplements.

Based on Bioinformatics to Explore the Mechanism of “Tangzhiqing” Decoction Alleviating Type 2 Diabetes-associated Cognitive Dysfunction in Mice by Regulating Hippocampal Neuron Apoptosis and Autophagy
Authors: Shi Yinli , Sheng Pei , Zhao Yun , Wang Xu , Xu Xiru , Sun Sifan
Published: November 2023

Background:

Diabetic cognitive dysfunction (DCD) is emerging as a chronic complication
of diabetes that is gaining increasing international recognition. The traditional Chinese
medicine (TCM) formulation, Tangzhiqing decoction (TZQ), has shown the capacity to modulate
the memory function of mice with DCD by ameliorating insulin resistance. Nevertheless, the
precise mechanism underlying the effects of TZQ remains elusive.

Methods:

The chemical constituents of TZQ were screened using TCMSP databases, and DCDassociated
disease targets were retrieved from various databases. Subsequently, core targets were
identified through network topology analysis. The core targets underwent analysis using Gene
Ontology (GO) functional annotations and enrichment in the Kyoto Encyclopedia of Genes and
Genomes (KEGG) pathways. Models were established through high-fat and high-glucose diet
feeding along with intraperitoneal injection of streptozotocin (STZ). TZQ and metformin were
administered at varying doses over 8 weeks. The Morris water maze was employed to evaluate
the cognitive capabilities of each rat group, while indicators of oxidative stress and insulin were
assessed in mice. Neuronal apoptosis in distinct groups of mice's hippocampi was detected using
TdT-mediated dUTP Nick-End Labeling (TUNEL), and western blot (WB) analysis was conducted
to assess the expression of apoptosis- and autophagy-related proteins, including Bax,
Bcl2, Caspase3, Caspase8, Beclin1, ATG7, LC3, p62, and Lamp2, within the hippocampus.

Results::

TZQ exhibited the capacity to modulate neuronal autophagy, ameliorate endoplasmic
reticulum stress, apoptosis, inflammation, and oxidative stress, as well as to regulate synaptic
plasticity and conduction. TZQ mitigated cognitive dysfunction in mice, while also regulating
hippocampal inflammation and apoptosis. Additionally, it influenced the protein expression of
autophagy-related factors such as Bax, Bcl2, Caspase3, Caspase8, Beclin1, ATG7, and LC3. Notably,
this modulation significantly reduced neuronal apoptosis in the hippocampus and curbed
excessive autophagy.

Conclusion:

TZQ demonstrated a substantial reduction in neuronal apoptosis within the hippocampus
and effectively suppressed excessive autophagy.

Authors: Jiang Xianqiong , Gao Li , Li Zhilong , Shen Yan , Lin Zhi-Hua
Published: November 2023

Cyclic peptides are polypeptide chains formed by cyclic sequences of amide bonds between
protein-derived or non-protein-derived amino acids. Compared to linear peptides, cyclic
peptides offer several unique advantages, such as increased stability, stronger affinity, improved
selectivity, and reduced toxicity. Cyclic peptide has been proved to have a promising application
prospect in the medical field. In addition, this paper mainly describes that cyclic peptides play an
important role in anti-cancer, anti-inflammatory, anti-virus, treatment of multiple sclerosis and
membranous nephropathy through immunomodulation. In order to know more useful information
about cyclic peptides in clinical research and drug application, this paper also summarizes cyclic
peptides currently in the clinical trial stage and cyclic peptide drugs approved for marketing in the
recent five years. Cyclic peptides have many advantages and great potential in treating various diseases,
but there are still many challenges to be solved in the development process of cyclic peptides.

Published: November 2023

Cancer presents a significant medical challenge that requires effective management.
Current cancer treatment options, such as chemotherapy, targeted therapy, radiotherapy,
and immunotherapy, have limitations in terms of their efficacy and the potential harm they
can cause to normal tissues. In response, researchers have been focusing on developing
adjuvants that can enhance tumor responses while minimizing damage to healthy tissues.
Among the promising options, nanoceria (NC), a type of nanoparticle composed of cerium
oxide, has garnered attention for its potential to improve various cancer treatment regimens.
Nanoceria has demonstrated its ability to exhibit toxicity towards cancer cells, inhibit invasion,
and sensitize cancer cells to both radiation therapy and chemotherapy. The remarkable aspect
is that nanoceria show minimal toxicity to normal tissues while protecting against various
forms of reactive oxygen species generation. Its capability to enhance the sensitivity of
cancer cells to chemotherapy and radiotherapy has also been observed. This paper thoroughly
reviews the current literature on nanoceria's applications within different cancer treatment modalities,
with a specific focus on radiotherapy. The emphasis is on nanoceria's unique role in
enhancing tumor radiosensitization and safeguarding normal tissues from radiation damage.

Niveles de competencia y uso de tarjetas de crédito en México. Un enfoque de mercados de dos lados
Authors: Canales-Medina Rafael , Sempere Jaume
Published: November 2023

El objetivo de este artículo es analizar la relación entre el volumen de los pagos con tarjeta de crédito con indicadores de competencia de los dos lados del mercado (emisor y adquirente), además del número de terminales y de tarjetas per cápita. Este es el primer estudio que incorpora indicadores de competencia como posibles determinantes del uso de las tarjetas en la economía mexicana. La metodología usada se basa en un análisis econométrico de series de tiempo. Nuestros resultados indican que el determinante más importante del uso de tarjetas es el número de terminales per cápita, mientras que los niveles de competencia no tienen efectos significativos sobre este uso. La recomendación más importante es que para promover el uso de medios electrónicos, más que otros programas, habría que estimular la instalación de terminales por parte de los bancos. Una forma de hacerlo, por ejemplo, es reduciendo las tasas de intercambio entre bancos. Los datos públicos que analizamos son de tipo macroeconómico y no permiten analizar efectos locales o regionales o de comportamiento individual.
Electronic Interactive Games for Glycemic Control in Individuals With Diabetes: Systematic Review and Meta-Analysis (Preprint)
Authors: Yao WenQi , Han YiBing , Yang Li , Chen Ying , Yan ShengZhe , Cheng YanZhen
Published: November 2023

BACKGROUND

Several electronic interventions have been used to improve glycemic control in patients with diabetes. Electronic interactive games specific to physical activity are available, but it is unclear if these are effective at improving glycemic control in patients with diabetes.

OBJECTIVE

This study aimed to determine the effects of electronic game–based interventions on glycemic control in patients with diabetes.

METHODS

Relevant studies that were published before April 1, 2023, were searched from 5 databases: PubMed, Embase, Web of Science, Scopus, and Cochrane Library. Eligibility criteria included prospective studies examining the relationship between electronic games with physical activities or diet education and glycemic control as the outcome. The risk of bias was assessed using the Cochrane risk-of-bias tool. All analyses were conducted using RevMan5.4.1. Depending on the heterogeneity across studies, the pooled effects were calculated using fixed-effects or random-effects models.

RESULTS

Participants from 9 studies were included and assessed. Glycated hemoglobin (HbA1c) and fasting blood glucose improved in the intervention group, although the analysis revealed no significant reduction in HbA1c (−0.09%, 95% CI −0.29% to 0.10%) or fasting blood glucose (−0.94 mg/dL, 95% CI −9.34 to 7.46 mg/dL). However, the physical activity of individuals in the intervention group was significantly higher than that of those in the control group (standardized mean difference=0.84, 95% CI 0.30 to 1.38; P=.002). Other outcomes, such as weight and blood lipids, exhibited no significant improvement (all P>.05).

CONCLUSIONS

Electronic games had a good impact on participants’ physical activity and offered an advantage in glycemic control without reaching statistical significance. Electronic games are convenient for reminders and education. Low-intensity exercise games may not be considered a better adjuvant intervention to improve diabetes self-management care.

Published: November 2023

La música siempre ha formado parte del ser humano, pues se ha encontrado en todas las culturas. Dependiendo del tipo de música, esta puede tener diversos efectos sobre nosotros, pero uno de los más importantes es que puede ser utilizada como terapia para algunas enfermedades psiquiátricas. A esto se le conoce como musicoterapia, la cual utiliza la música con el objetivo de mejorar la calidad de vida de los pacientes y en los últimos años ha recibido una mayor atención. Así como muchos de nosotros sentimos alegría al escuchar nuestra canción favorita, las investigaciones han demostrado que la música mejora los síntomas, principalmente emocionales, en pacientes con depresión, ansiedad y esquizofrenia, entre otros. Asimismo, también puede mejorar las habilidades sociales en pacientes con trastorno del espectro autista y a las personas con demencia les ayuda a recordar acontecimientos vividos previamente. Aunque aún falta mucho por descubrir con respecto a los beneficios obtenidos con la música y, dado que las enfermedades mentales son complejas, el uso de medicamentos en conjunto con la musicoterapia puede ofrecer mayores resultados y más duraderos. Es importante mencionar que la musicoterapia es una gran herramienta que, además de sus múltiples beneficios, no genera efectos secundarios.

Experimental Study on Partial Replacement of Cement by GGBS and Fly Ash in Conventional Concrete
Authors: Rao K. Gopala
Published: November 2023

Abstract: Cement concrete is widely used in industrial plants, civil infrastructures, wastewater treatment plants and pipelines. It is a highly prone to acid attacks from the surrounding environment. Since acidic environments will accelerate the deterioration of concrete, various types of polymer coating materials are being used to protect the concrete surfaces. Hence an attempt has been made in this investigation on partial replacement of cement with GGBS along with incorporation of fly ash of 20% of the volume of concrete. Various strength parameters of the concrete specimens are tested. The combination used is GGBS with 10%, 20%, 30%, 40% by the weight of cement for M25 grade concrete at an age of 7 days, 28 days and 56 days. Cubes are cast, curried and tested to assess the influence of partial replacement of cement with fly ash and GGBS and then found the optimum content as 20% of GGBS and fly ash 20% from the experimental results. Then final combination is 20% of cement with GGBS along with incorporation of fly ash of 20% percentages of the volume of concrete. The compressive strength values are increased by 10% than those of conventional concrete mixture at a mixture prepared with 20% GGBS and 20% Fly ash. Further increase in GGBS percentage with constant fly ash percentage proved its incompatibility nature where it is shown low strength when compared with controlled concrete mix. X-ray Diffraction (XRD) technique has also been used to get insights into the quality and composition of the concrete, aiding in the assessment of its suitability for specific construction applications.

Introduction Patients with food allergies necessite having personalized
information on their risk of reaction in “real-life” situations. This
multicentric study aimed to investigate the link during accidental
reactions between the nature and amount of food allergens consumed in
“real life situation” and the severity of the symptoms. Methods
Patients were prospectively recruited from the 1 of
December 2020 to the 31 of December 2021 at the
emergency departments in the Geneva University Hospitals and local
pediatric urgent care, trough the allergology outpatient consultation,
at school and daycare facilities and trough their primary care
physicians. Medical history of patients presenting reactions suggestive
with immediate food allergy and suspected food samples were collected.
Allergy diagnostic tests were retrospectively and prospectively
collected. The samples were analyzed for their allergen content. Results
We recruited 147 subjects with an accidental immediate-type allergic
reaction to a food. We were able to collect 115 reaction-eliciting food
samples allowing to quantify the allergen amount occasioning the
reaction, as well as correlating this amount to the severity of the
reaction. Children represented a large part of the reactors, and most
reactions were to common food allergens such as tree nuts, cow’s milk as
well as peanuts and hen’s egg. Reactions were mostly to pre-packaged
foods and seven were to products with Precautionary allergy labeling, or
without labelling to the corresponding allergen. Reactions were of
various degrees of severity, and independent to the amount of allergen
ingested. Discussion The severity of reactions did not show a direct
correlation with allergen quantity, emphasizing individual sensitivity.
Some reactions occurred with allergen amounts significantly below the
legal limit for mandatory labelling of 1 g/kg in Switzerland. The study
also highlighted considerable variability in allergen concentrations in
foods labeled with possible “contaminations” or “traces.” These
findings raise questions about the accuracy of allergen labeling and
regulations.
Neural Network Adaptive Hierarchical Sliding Mode Control for the Trajectory Tracking of a Tendon-Driven Manipulator
Authors: Zhang Yudong , He Leiying , Chen Jianneng , Yan Bo , Wu Chuanyu
Published: November 2023

Tracking control of tendon-driven manipulators has become a prevalent
research area. However, the existence of flexible elastic tendons
generates substantial residual vibrations, resulting in difficulties for
trajectory tracking control of the manipulator. This paper proposes the
radial basis function neural network adaptive hierarchical sliding mode
control (RBFNNA-HSMC) method, which combines the dynamic model of the
elastic tendon-driven manipulator (ETDM) with radial basis neural
network adaptive control and hierarchical sliding mode control
technology. The aim is to achieve trajectory tracking control of ETDM
even under conditions of model inaccuracy and disturbance. The Lyapunov
stability theory demonstrates the stability of the proposed RBFNNA-HSM
controller. In order to assess the effectiveness and adaptability of the
proposed control method, simulations and experiments were performed on a
two-DOF ETDM. The RBFNNA-HSM method shows superior tracking accuracy
compared to traditional model-based HSM control. The experiment shows
that the maximum tracking error for ETDM double-joint trajectory
tracking is below 2.593×10 rad and 1.624×10
rad, respectively.

Objectives: Mental-health issues accounted for 418 million
disability-adjusted life years in 2019, costing the world economy
approximately US$5 trillion. Untreated hearing loss is a well-known
modifiable risk factor for mental-health issues, with severe-to-profound
hearing loss having the largest impact. Therefore, treatment of
severe-to-profound hearing loss, namely with cochlear implantation,
could help to alleviate psychological distress. However, previous
studies have failed to include comprehensive measures of mental health
or adequate controls. The current study thus aimed to conduct a
controlled, longitudinal investigation of how cochlear implantation
affects depression, anxiety, and stress levels. Participants:
Participants were 87 adults assigned to conditions based on hearing
status: normal hearing ( n = 44), received cochlear implant (
n = 26), or untreated hearing loss ( n = 17). Main
Outcome Measures: The short-form Depression Anxiety Stress Scale was
given at four timepoints (baseline, three months, six months, 12
months). Data were analysed with linear mixed-effects modelling.
Results: Results showed that cochlear implants helped to
stabilise anxiety and stress symptoms, while depression symptoms were
observed to worsen over time despite treatment. Conclusion: Our
findings suggest that treatment of severe-to-profound hearing loss with
cochlear implantation can help to alleviate associated anxiety and
stress symptoms; associated depressive symptoms did not benefit. Due to
the current study’s non-randomised treatment allocation, future
randomised controlled trials are required for confirmation. The present
findings help inform clinical and societal interventions for
mental-health issues associated with hearing loss.
Exploring Variable Synergy in Multi-Task Deep Learning for Hydrological Modeling

Published: November 2023

Despite advances in hydrological Deep Learning (DL) models using Single
Task Learning (STL), the intricate relationships among multiple
hydrological components and model inputs might not be comprehensively
encapsulated. This study employed a Long Short-Term Memory (LSTM) neural
network and the CAMELS dataset to develop a Multi-Task Learning (MTL)
model, predicting streamflow and evapotranspiration across multiple
basins. An optimal multi-task loss weight ratio was determined manually
during the validation phase for all 591 selected basins with streamflow
data-gaps under 5%. During test period, MTL showed median
Nash-Sutcliffe Efficiency predictions for streamflow and
evapotranspiration at 0.69 and 0.92, consistent with two STL models. The
MTL’s strength appeared when predicting the non-target variable, surface
soil moisture, using probes derived from LSTM cell
states—representative of the internal DL model workings. This
prediction showed a median correlation coefficient of 0.90, surpassing
the 0.88 and 0.89 achieved by the streamflow and evapotranspiration STL
models, respectively. This outcome suggests that MTL models could reveal
additional rules aligned with hydrological processes through the
inherent correlations among multiple hydrological variables, thereby
enhancing their reliability. We termed this as “variable synergy,”
where MTL can simultaneously predict varied targets with comparable STL
performance, augmented by its robust internal representation. Harnessing
this, MTL promises enhanced predictions for high-cost observational
variables and a comprehensive hydrological model.
Characteristics of Station-Derived Convective Cold Pools Over Equatorial Africa

Due to their potential role in organizing tropical mesoscale convective
systems, a better understanding of cold pool (CP) dynamics in such
regions is critical, particularly over land where the diurnal cycle
further concentrates convective activity. Numerical models help
disentangle the processes involved but often lack observational
benchmark studies. To close this gap, we analyze nearly 43 years of
five-minute resolution near-surface timeseries records from twelve
automatic weather stations across equatorial Africa. We identify 4289
CPs based on criteria for temperature and wind. The identified CP gust
fronts, which exhibit respective median temperature and specific
humidity decreases of 5.2 K and 2.8 g/kg, closely correlate with
satellite-observed brightness temperature discontinuities. Despite weak
diurnal variation in precipitation, observed CP occurrence shows a
pronounced diurnal cycle with an afternoon peak — a finding we
attribute to low-level moisture conditions. Our findings can serve as
observational benchmark to improve simulations of CP organization.
Rapid semi-quantitative identification of greigite in lacustrine sediments using SIRM/χ and χARM: Insights from the Cuo E core, Tibetan Plateau, China

Published: November 2023

The Cuo E (CE) core contains the entire Quaternary stratigraphy of the
Cuo E Lake (31°24′ - 31°.32′ N, 91°28′ - 91°33′E, Tibetan Plateau,
China). Here, we study the magnetic properties of 1748 samples from the
CE core, combined with scanning electron microscopy and X-ray energy
dispersive spectrometer analysis on selected samples. The main magnetic
minerals appear to be magnetite and greigite. To further quantify the
presence of greigite in CE core, 84 samples were rock magnetically
analyzed in more detail including: susceptibility (χ) vs. temperature,
coercivity component analysis of acquisition curves of the isothermal
remanent magnetization (IRM), and Principal component analysis (PCA) of
the first-order reversal curve (FORC) diagrams.The greigite content and saturation IRM over susceptibility (SIRM/χ)
appear to be exponentially related. SIRM/χ can be used as greigite
concentration indicator. We also propose a rapid way to identify
greigite in the CE core: When the SIRM/χ value increases and
anhysteretic remanent susceptibility (χARM) increases only slowly, the
sample contains greigite. Samples with SIRM/χ < 15kAm-1 also
obey this relation. This method has a lower limit of detection than the
traditionally used SIRM/χ parameter for greigite detection. It is also
faster than FORC analysis and thus particularly suitable for analysis of
large sample collections. Twenty greigite-bearing layers were identified
in the CE core using this method. The location of the Jaramillo subchron
in the CE core is controversial in the currently available
magnetostratigraphy, possibly related to the presence of greigite in
this core interval.
Reciprocating plate column - fundamental research and application in Serbia from 1970 to 2020
Authors: Veljkovic Vlada , Bankovic-Ilic Ivana , Skala Dejan
Published: November 2023

In the group of multiphase contactors and reactors, an important place belongs to reciprocat-ing plate columns (RPCs), which consist of a set of perforated plates fixed on a carrier (the so-called reciprocating or vibrating agitator) moving periodically up and down through a column. This construction maximizes the positive effects of mechanical agitation and minimizes or eliminates the adverse effects characteristic of column-type contactors and reactors. In RPCs, the highest dispersed-phase holdup is achieved at a lower dispersed-phase velocity due to the influence of mechanical agitation on the bubble or drop comminution. Therefore, this device can be the most acceptable contactor or reactor for performing complex actions in multiphase systems. The paper reviews the fundamental research and application of RPCs in Serbia in the last fifty years, from 1970 to 2020. Hydrodynamic and mass-transfer characteristics are analyzed, such as the pressure variation at the column bottom, power consumption, dispersed-phase holdup, axial dispersion, liquid mass transfer coefficient, specific interfacial area, and volumetric mass transfer coefficient. The use of RPCs as reactors in bioprocesses and biodiesel production processes is also discussed.

Published: November 2023

Introduction. The Nursing Activities Score is used to quantify, assess, and
identify the workload of nurses in intensive care units, and is widely
considered a very effective, simple, standardized measurement scale,
sufficiently detailed to be implemented in everyday hospital practice. The
aim of the study is to evaluate the workload of nurses using the results of
the Nursing Activities Score and compare the nurse-to-patient ratio with
regulations in our country. Material and Methods. The study included 131
patients who underwent cardiac surgery in the period from November 1 to
November 30, 2021. Surgical data and corresponding Nursing Activities Score
values were obtained from hospital information system. In the intensive care
unit, nursing activities were monitored and scored daily. Results. Using the
Nursing Activities Score, 344 measurements were recorded in the study
sample. The mean Nursing Activity Score was 88.27 ? 3.63, and the highest
was 102.97 ? 1.89 on the first postoperative day. The nurse-to-patient ratio
was 1.03:1 on the first postoperative day, and about 0.8:1 on the second and
third postoperative days. There was a statistically significant difference
in the mean Nursing Activities Score between postoperative days (p < 0.0005)
between the first and second day (102.96 vs. 79.46) and the first and third
day (103.46 vs. 83.58). Conclusion. On the first postoperative day, the
optimal number of nurses according to the Nursing Activities Score is higher
compared to the State Regulations, while for the rest of the days in the
intensive care unit the nurse-to-patient ratio corresponds to the
regulations.
Prosthetic heart valve thrombosis - a headache for the heart team: A case report
Authors: Majdevac Slavica , Preveden Andrej , Dracina Nina , Bakic Nikola , Preveden Mihaela , Susak Stamenko
Published: November 2023

Introduction. Prosthetic valve thrombosis is usually a subacute or chronic
condition, although it may also present with a fresh thrombus. It occurs in
two forms: obstructive and non-obstructive thrombosis. Case Report. We
present a case of a female patient who underwent mitral valve replacement
with mechanical prosthesis due to severe mitral stenosis. The postoperative
course was uneventful and the patient was discharged on vitamin K antagonist
therapy with international normalized ratio target 3.0. Five months later,
the patient was admitted with severe shortness of breath and signs of acute
heart failure. International normalized ratio at that moment was 2.3.
Transthoracic echocardiography indicated severely raised gradient across the
prosthetic valve and mechanical valve malfunction was suspected.
Cinefluoroscopy showed that one of the prosthetic valve leaflets was
completely immobile. Transesophageal echocardiography definitely confirmed
thrombosis of the prosthetic valve with large multiple thrombi that
completely fixed one leaflet in closed position, and partially limited the
motion amplitude of the other leaflet. There were thrombi floating between
the left ventricle and left atrium. Thrombectomy of the prosthetic valve was
performed, which was sufficient for the complete restoration of the
mechanical valve function. The vitamin K antagonist dosage was carefully
up-titrated in order to reach and maintain the target international
normalized ratio of 3.0. Conclusion. Prosthetic valve thrombosis is a
serious and life-threatening condition that requires urgent management.
Coordination and cooperation of the whole heart team is necessary for
optimal choice of treatment, which primarily includes surgery or
fibrinolysis.
