Aunque ha surgido cada vez con más fuerza una línea investigativa centrada en comprender la actividad emprendedora como una de múltiples aristas, vinculada a su composición biográfica, social, educacional y cultural, se vislumbra, aun así, cierto vacío empírico al momento de indagar las formas concretas que adquiere la vinculación entre la educación superior y el ámbito emprendedor. Este trabajo se construyó con el deseo de aportar contenido en este sentido, y con el objetivo de analizar las estrategias actualmente implementadas para fomentar la educación para el emprendimiento en la Universidad Nacional de Mar del Plata (Argentina), considerando exclusivamente la perspectiva de estudiantes de pregrado. En este sentido, resulta posible decir que se recogieron técnicas propias de la metodología cualitativa, específicamente en lo que refiere a la estrategia de investigación del estudio de caso único y el uso del método de la Teoría Fundamentada, mediante el cual fue tomado un cuestionario a una muestra teórica de 106 estudiantes de pregrado. Los resultados demuestran que entre las estrategias actuales de mayor envergadura se destacan el desarrollo de perfiles emprendedores en los estudiantes y estrategias de enseñanza- aprendizaje, específicamente dirigidas al desarrollo de emprendimientos. Se concluye que la Universidad Nacional de Mar del Plata fomenta el desarrollo de ciertas estrategias emprendedoras, aunque debiera incursionar en un plan estratégico, sistematizado y riguroso, a la altura de las necesidades educativas, laborales y sociales de su comunidad.
Alpha-NETA, as a CMKLR1 Small Molecule Antagonist, Protects against
Renal Ischemia Reperfusion Injury in Mice
Authors: Peng Xue , Wang Wenjuan , Wang Wenhao , Qi Jingrui
Published: August 2022

Background:

Ischemia-reperfusion (IR) injury is one of the major causes of acute kidney
injury (AKI). Chemerin chemokine-like receptor 1 (CMKLR1) has been reported to be involved in the
progression of IR injury. Here, we investigated the protective role of CMKLR1 antagonist, α-NETA, in
IR mouse model, and dissected the underlying regulatory mechanism.

Methods:

IR injury mouse model was established to evaluate the protective effects of α-NETA on IR
injury. Kidney injury-associated parameters and functions were examined to evaluate the renal function
of Sham, IR, and IR+ α-NETA mice. Renal morphological changes and apoptosis were determined by
PAS and TUNEL staining in IR and α-NETA treated mice. ELISA, RT-qPCR, and western blot were
performed to examine the inflammatory responses and expression of CMKLR1.

Results:

α-NETA administration attenuated IR-induced renal tubular injury and epithelial cell apoptosis
in IR injury mice. Kidney injury-related cystatin C, kidney injury molecule-1, neutrophil gelatinaseassociated
lipocalin, and renal morphology were significantly improved. Mechanistically, α-NETA
suppressed the inflammatory responses by inhibiting the expression of CMKLR1, and then protected
the IR-induced renal damage and restored renal function.

Conclusion:

CMKLR1 plays an important role in renal ischemia-reperfusion injury, targeting
CMKLR1 by using the small molecule inhibitor α-NETA is a potential treatment strategy for AKI.
Effect of Myrcene on Th17/Treg Balance and Endocrine Function in
Autoimmune Premature Ovarian Insufficiency Mice through the MAPK
Signaling Pathway
Authors: Hu Fengying , Zhou Xianwei , Jiang Yanjiao , Huang Xinhe , Sheng Shaoqin , Li Dongsheng
Published: August 2022

Background:

Premature ovarian insufficiency (POI) is a defect of ovarian functions in
women younger than 40 years old. Although a large number of studies have focused on investigating
autoimmune POI, its detailed pathogenesis is still largely unknown. Several studies have indicated that
Myrcene exerted a part in the biological processes of various diseases. Nonetheless, whether Myrcene
could influence the development of autoimmune POI remains to be elucidated.

Methods:

POI model was established by injecting zona pellucida glycoprotein 3 (pZP3). Hematoxylin
and eosin (H&E) staining was applied to evaluate the pathological features of ovarian tissues. Enzymelinked
immunosorbent assay (ELISA) was used for assessing the concentrations of estradiol (E2),
follicle-stimulating hormone (FSH), luteinizing hormone (LH), anti-Müllerian hormone (AMH) and
interleukin (IL)-17. Flow cytometry analysis was conducted for assessing the balance of Th17/Treg
cells.

Results:

The results showed that decreased levels of body weight, ovarian weight and ovarian index
were reversed by Myrcene in POI model mice. The estrous cycles in mice were extended in pZP3 mice
and Myrcene administration restored it to normal. The reduced number of primordial, primary, and
secondary follicles as well as the increased number of atretic follicles in POI mice were offset by
Myrcene administration. Moreover, Myrcene could modulate the Th17/Treg balance in autoimmune
POI. Besides, Myrcene suppressed the MAPK signaling pathway in pZP3 mice.

Conclusion:

Myrcene regulated the Th17/Treg balance and endocrine function in autoimmune POI
mice through the MAPK signaling pathway, which might provide a reference for improving the
treatment of autoimmune POI.
LncRNA DSCAM-AS1: A Pivotal Therapeutic Target in Cancer
Authors: Hu Chengyu
Published: August 2022

Background:

LncRNAs are an emerging category of non-coding RNAs. LncRNAs are
usually greater than 200 nucleotides in length and do not possess protein editing capabilities.
DSCAM-AS1 is a highly valued member of the lncRNAs family. Numerous studies have revealed
the involvement of the oncogene DSCAM-AS1 in multiple biological processes, including metastasis,
aggressiveness and cell proliferation. This review discusses the molecular mechanisms and
clinical significance of DSCAM-AS1 in various tumor types.

Methods:

This paper analyzes and summarizes current research by searching PubMed using
“DSCAM-AS1” and “tumor” as keywords.

Results:

DSCAM-AS1 is a valuable tumor-associated lncRNA with significant oncogenic effects.
It is abnormally expressed in a variety of cancers, such as non-small cell lung cancer, cervical
cancer, osteosarcoma, colorectal cancer, breast cancer, gastric cancer and endometrial cancer. The
overexpression of DSCAM-AS1 promotes cancer progression by modulating cancer cell proliferation,
invasion, distant metastasis, and resistance.

Conclusion:

DSCAM-AS1 is upregulated and acts as an oncogene in multiple tumors. As more
systematic studies are performed, DSCAM-AS1 may prove to be a promising therapeutic target or
tumor biomarker.

Authors: Rasheed Ashraf S. , Fadhil Ayad K. , M. Hassan Mohammed Jasim
Published: August 2022

Background:

Angiotensin II receptor blockers (ARBs) are helpful medications for
treating hypertension and heart failure and have been proposed as a possible alternative to standard
angiotensin-converting enzyme inhibitors.

Objective:

The present article describes and validates sensitive hydrophilic interaction liquid
chromatography methods to simultaneously analyse four angiotensin II receptor blockers: valsartan,
telmisartan, losartan, and irbesartan.

Method:

Numerous chromatographic parameters were studied and optimized in detail. As a mobile
phase, the best separation was obtained on two handmade columns (ZIC-S1 and ZIC-S4) using
acetonitrile/sodium acetate buffer (40 mM, pH 4.75). The detection of target pharmaceuticals
was obtained at 220 nm.

Results:

The linear ranges of target drugs (valsartan, telmisartan, losartan, and irbesartan) were
0.02-4, 0.06-7, 0.005-6 and 0.08-5 μg/mL on the ZIC-S1 and ZIC-S4 columns, respectively. The
suggested methods demonstrated high precision (RSD ≤ 1.15), linearity (r2 ≥ 0.9964), and accuracy
(between 98.88 and 101%) with detection and quantitation limits of (0.0021-0.0550 and
0.0063-0.1666 μg/mL, respectively) for all target pharmaceuticals.

Conclusion:

The suggested methods have been validated and applied to pharmaceutical formulations,
indicating that it is suitable for therapeutic drug monitoring of these medications.

Collateral Artery
Authors: Esmaeilzadeh Hossein , Rezaei Nima , Aminorroaya Arya , Rayzan Elham , Shahkarami Sepideh , Seyedpour Simin , Zoghi Samaneh , Aryan Zahra , Somekh Ido , Rohlfs Meino , Klein Christoph
Published: August 2022

Background:

Immunodeficiency, centromeric instability, and facial anomalies (ICF) syndrome
is a rare autosomal recessive disorder. ICF1 is caused by bi-allelic mutations in the gene encoding
deoxyribonucleic acid methyltransferase-3B (DNMT3B). Herein, we report a novel homozygous
DNMT3B mutation in a patient with ICF1.

Case Presentation:

An eight-month-old Iranian Caucasian infant of consanguineous 1st-degree cousins
presented to our clinic for evaluation of neutropenia. Physical examination was unremarkable
except for low-set ears and a systolic cardiac murmur. He had a history of recurrent respiratory infections
and oral thrush. Moreover, a collateral artery between the bronchial and pulmonary arteries
was observed on the angiogram, mimicking a patent ductus arteriosus on the echocardiogram. Growth
percentiles were normal; however, he had a neurodevelopmental delay. Family history was significant
for a sibling who deceased at nine months of age after recurrent respiratory infections. Laboratory
evaluation revealed a normal white blood cell count with neutropenia and normal bone marrow
studies. He had hypogammaglobinemia with normal flow cytometric studies and was treated with
prophylactic trimethoprim-sulfamethoxazole and itraconazole. After that, he was re-admitted three
times due to recurrent episodes of pneumonia and an episode of pseudomonas aeruginosa meningitis.
Currently, he is five years old and doing well on monthly intravenous immunoglobulin. Due to recurrent
infections, hypogammaglobulinemia, and neutropenia, as well as a family history of consanguinity
and a sibling who deceased during infancy, a primary immune deficiency was suspected.
Genetic studies utilizing whole-exome sequencing demonstrated a homozygous missense mutation
in DNMT3B (LRG_56t1:c.2008C>T; p.Arg670Trp) in the patient studied. The mutation has not been
previously reported.

Conclusion:

We describe a novel homozygous DNMT3B mutation in an Iranian boy with ICF1. It is
associated with recurrent infections, hypogammaglobinemia, neutropenia, mild facial anomalies, and
a bronchopulmonary collateral artery.

Authors: Nezhad Anahita Marhounian , Farshad Omid , Morowvat Mohammad Hossein
Published: August 2022

Background:

Nanotechnology and nanobiotechnology have emerged as novel
technologies for the production and application of nanoscale materials in different pharmaceutical,
medical, and biological fields. Besides, there are a bunch of recently published
patents in this field. Although Carbon Nanotubes (CNTs) have various advantages and can
be applied for a wide variety of purposes, their toxicity on humans is a matter of concern.

Objective:

This study aimed to evaluate six different types of CNTs, including pristine,
carboxylated, and hydroxylated single-walled CNTs (SWCNTs) and multi-walled CNTs
(MWCNTs) on three human cell lines.

Methods:

MTT assay was employed to assess the cytotoxicity of six types of CNTs, including
pristine, carboxylated, and hydroxylated forms of SWCNTs and MWCNTs on
three different human cell lines.

Results:

The findings of the MTT assay showed that the six different types of CNTs (100-
600 μg/mL) exhibited different levels of cytotoxicity on the three human cell lines. The
observed trend presented dose-dependent cytotoxicity on the three studied cell lines, including
pulmonary, skin, and gastrointestinal cell lines. SWCNT-COOH and MWCNTs
accounted for the lowest cell viability in the three human cell lines.

Conclusion:

In conclusion, researchers and industrial workers are recommended to be cautious
while working with different types of CNT because all their toxicity dimensions have
not been determined yet.
Varying Effects of Iron Oxide Nanoparticles (IONPs) on the Bacterial
Cells

Published: August 2022

Nanoparticles have a wide range of responsive reactions in bacterial cells depending on their
characteristics. They interact with organisms at a cellular level and are capable of producing unexpected
reactions depending on their own and cell’s morphological features. Some functions provide betterment
of cells and some cause disruptions in the cell functioning or exhibit toxicity for them. Nanoparticles,
depending on their toxicity, can also cause alterations in cellular physiology. Different nanoparticles affect different biological species in different ways. As a result, a comprehensive investigation is necessary
for all types of nanoparticles to demonstrate their beneficial and harmful effects on various species in
terms of growth, inhibition, toxicity, and death. In this review, we have only focused on the iron nanoparticle and their effects on bacterial cells as they are the most commonly used nanoparticle in biology and
microbiology because of their unique physicochemical properties (size, shape, stability, etc.). These properties of NPs allow them to react with the bacterial cell surfaces and create a response (which can either
support the growth of the bacteria or cause an anti-bacterial or anti-microbial effect on them). These
properties are also changeable if we alter the morphological features of the NPs. Studies have shown improvement in microbiological reaction rates by using magnetic nanoparticles. However, nanoparticle toxicity is the major area of concern, as it can decrease therapeutic efficiency and cause adverse effects. Considering the wide range of responses and their reasons, this review summarizes the effects an iron oxide
nanoparticle can have on the bacterial cell in general, the factors that influence those effects, and the relation of NP's characteristics to their significant differences in effects on bacteria.
Microwave Assisted Synthesis of a Novel Schiff Base Scaffolds of Pyrazole
Nuclei: Green Synthetic Method
Authors: Kumar Dileep , Karati Dipanjan , Mahadik K.R.
Published: August 2022

Aim:

The research aims to develop a sustainable microwave-assisted scheme for Synthesizing
5-(benzylidene amino)-1-phenyl-1H-pyrazole-4-carbonitrile congeners.

Background:

5-(benzylideneamino)-1-phenyl-1H-pyrazole-4-carbonitrile scaffolds are novel molecules
having various pharmacological activities such as neurodegenerative, anti-microbial, anticancer.
Schiff base congeners are considered as efficient pharmacophores for research. These activities
are due to the presence of azomethine (CH=N) group in the Schiff base compounds.

Objectives:

To synthesise different novel Schiff base compounds of pyrazole nuclei by green
chemistry with a decent yield.

Methods:

The 5-(benzylideneamino)-1-phenyl-1H-pyrazole-4-carbonitrile scaffolds were prepared
by two-step reactions. Both steps were microwave-assisted. The first step was to synthesize 5-
amino-1-phenyl-1H-pyrazole-4-carbonitrile as an intermediate compound. This compound was
synthesized by using phenyl hydrazine and 2-(ethoxymethylene)malononitrile. The temperature,
pressure, and time required for this reaction were 102°C, 300W, and 45 minutes respectively.
In the second step, the final Schiff base congeners were attained by reacting this compound with
several aromatic aldehydes. The yield, reaction condition, and time consumption were all acceptable
for the green synthetic methods rather than the conventional schemes.

Results:

The microwave-assisted method was more efficient. The reactions were less timeconsuming,
and the overall yield of the all-synthesized compounds was 75-82%. Different spectroscopic
methods characterized the synthesized congeners. The IR peak is considered the main functional
group (azomethine) at 1611 cm-1 wavelength.

Conclusions:

This microwave-assisted synthetic scheme thus appears more environmentally due
to a significant reduction in organic solvents, resulting in fewer hazardous residues. Using this
scheme, we prepared different Schiff base congeners with satisfactory chemical yields.

Large volume variation during charge/discharge of silicon (Si) nanostructures applied
as the anode electrodes for high energy lithium-ion batteries (LIBs) has been considered the most
critical problem, inhibiting their commercial applications. Searching for alternative high performance anodes for LIBs has been emphasized. Silicon carbide (SiC) nanomaterials, a wide
bandgap semiconductor with excellent mechanical properties, have been investigated as anode
electrode materials even as active materials, protective layers, or inactive buffer stuff. In this mini review, we briefly summarize the synthesis of SiC nanostructures, the application of SiC/C anode
materials, and SiC/Si composite anodes in LIBs.

Published: August 2022

The relationship between the environment and economy and people's consumption is still contradictory in efforts to save the environment. Excessive consumption and production patterns lead to polluted rivers. This qualitative research aims to describe the management of the Batang Arau watershed from a GEG perspective. Primary data was collected with in-depth interviews regarding the condition. Secondary data was obtained study of documentation related to laws and regulations. Informants are determined by the purposive sampling method (Sugiyono, 2017). Informants are parties related to the watershed. Data obtained were analyzed with Manual Data Analysis Procedure (MDAP) technique 1. Results showed the management of the Batang Arau watershed had not been implemented following principles of Good Environmental Governance; findings in the field found that; Public awareness is low, the law of environmental protection has not been optimal, and access to industrial waste information has not been opened, the government response is quite good, and environmental consensus has not been reached, there is a sectoral ego, a long bureaucratic path, environmental responsibility is lacking. Constraints, unified management vision among stakeholders, insufficient budget and fleet, low supervision, IPAL facilities have not integrated, Illegal logging, and inter-sectoral coordination are still problematic. Efforts made by the government: Conducting socialization to the community, cleaning and dredging watershed, and normalizing and rehabilitating critical land. Management must be carried out thoroughly, so there is no gap between upstream and downstream. We argue to create a balanced ecosystem. The government needs to improve management as a whole with a Good Environmental Governance approach in every management action to create sustainable management.

Na temelju provedenog terenskog istraživanja pojavnosti nasilja nad Romkinjama u romskim obiteljima, kao i njihovih uvjerenja i stavova o nasilju nad Romkinjama u romskim obiteljima koje je bilo provedeno na uzroku od 350 Romkinja koje žive na području 12 izoliranih romskih naselja na području Međimurske županije, upotrebom logističke regresijske analize izrađena su tri prediktivna modela profila Romkinje kao žrtve obiteljskog nasilja u romskoj obitelji. Aplikativni cilj istraživanja bio je usmjeren prema pomoći nadležnim zdravstvenim i socijalnim službama, kako bi na vrijeme mogle usmjeriti fokus svojeg rada prema onim Romkinjama kao korisnicama koje su pod većim rizikom od izloženosti nasilju. U prvom modelu, koji je uključivao samo sociodemografske karakteristike ispitanica, od prediktora izloženosti Romkinja obiteljskom nasilju unutar Romske obitelji prema Waldovu testu značajnosti koeficijenata kao statistički značajni izdvojeni su starija životna dob (OR 1,848, p - 0,007), veća materijalna deprivacija (OR 2,345, p - 0,021) i ranija dob rađanja prvog djeteta prije 16. godine života (OR 7,962, p - 0,004). Proširenjem modela sa stavovima i predrasudama o nasilju nad ženom uz već izdvojene značajni prediktore kao što su mlađa životna dob (OR 1,760, p - 0,015), ranija dob rađanja prvog djeteta (OR 8,210, p - 0,003) i ranija dob zasnivanja obitelji (OR 0,305, p - 0,048, kao najsnažniji prediktor izdvojena su uvjerenja i stavovi o nasilju (OR 1,957, p - 0,002), pri čemu Romkinje s većim stupnjem prihvaćanja predrasuda o nasilju imaju i veću šansu da budu žrtve nasilja. Konačno, uvođenjem kao nezavisne varijable i izloženost nasilju u djetinjstvu i to po pojedinim oblicima zlostavljanja (tjelesnom, psihičkom, seksualnom i ekonomskom), dobiven je prediktivni model koji se pokazao statistički značajnim (p < .01), a koji je od sva tri modela najbolje predviđao vrijednosti zavisne varijable, pri čemu su od prediktora bili značajni ranija dob rađanja prvog djeteta (OR 7,955, p - 0,041), ranija dob zasnivanja obitelji (OR 0,106, p - 0,017), veća brojnosti djece na skrbi (OR 3,087, p - 0,049) i izloženost tjelesnom (OR 14,560, p-0,001), ekonomskom (OR 4,728, p - 0,049) i psihičkom (OR 8,088, p - 0,000) nasilju u djetinjstvu. Izloženost nasilju u djetinjstvu toliko je snažan prediktor da njegovim uvođenjem u model stavovi o nasilju, odnosno veća sklonost prihvaćanja predrasuda o nasilju nad ženom te veća materijalna deprivacija gube prediktorsku snagu, čime je direktno potvrđena pretpostavka da su Romkinje koje su bile žrtve nasilja u djetinjstvu pod višestruko većim rizikom od bivanja žrtvom nasilja u odrasloj dobi.

Lattice thermal conductivity of solid solutions based on cobalt monosilicide and monogermanide was studied. Electrical and thermal conductivities of CoSi and solid solutions of CoGe(x)Si(1-x) (x=0.03 and 0.07) were experimentally measured in the temperature range of 80-350K. Phonon spectra and thermal conductivity in CoGe(x)Si(1-x) solid solutions were calculated using ab initio lattice dynamics. The results of calculations are in good agreement with the results of measurements obtained in the present work and with the literature data. It was shown that already at a content of 10–15 at.% of Ge, the lattice thermal conductivity decreases by about a factor of 2 compared with pure cobalt monosilicide, and at a germanium content of about 70 at.%, the decrease can reach 3.5 times.

Density functional theory with a gradient PBE functional and dispersion correction D3(BJ) in the basis of localized orbitals of the CRYSTAL17 package was used to study the effect of pressure on the structural, electronic, and elastic properties of K2Ca(CO3)2, K2Mg(CO3)2, Na2Ca2(CO3)3, Na2Mg(CO3)2. The parameters of the third-order Birch-Murnaghan equation of state are determined, and it is shown that the equilibrium volume and compressibility modulus depend linearly on the average cation radius. Under pressure, the widths of the upper valence bands increase maximally in K2Ca(CO3)2 and minimally in Na2Ca2(CO3)3, while the centers of gravity of the cationic states shift by ~0.2 eV. Elastic constants and polycrystalline moduli are calculated, which increase with decreasing average cation radius. The shear modulus for K2Ca(CO3)2 and K2Mg(CO3)2 decreases with increasing pressure, and this leads to anomalous behavior of the longitudinal and transverse acoustic wave velocities.

Experimental studies of the lattice parameters, thermal expansion, and elastic characteristics in the range of the structural phase transition in the YBaCo4-yZnyO7+x series of cobaltites with diamagnetic dilution of the cobalt subsystem have been carried out. It has been found that for stoichiometric samples annealed in vacuum, the parameter Delta a/a shows no features during the structural transition, while the parameters Delta b/b and Delta c/c experience similar jumps of different signs. This leads to a jump in anisotropic (rhombic) ε0~-4·10^-3 and isotropic (volume change) Delta V/V~ -1·10^-3 deformations. Upon substitution with Zn ions, the orthorhombic distortion of the structure changes slightly, and the jump in the volume anomaly (linear thermal expansion) changes sign. Structure distortion in stoichiometric samples is accompanied by characteristic anomalies in the Young's modulus Delta E(T)/E0 and internal friction in the TS range, while for nonstoichiometric quenched samples, the anomalies completely disappear. The diamagnetic substitution with Zn ions leads to a sharp decrease and then complete disappearance of the jump in the curve Delta E(T)/E0. This may be due to a change in the ratio of isotropic and anisotropic deformation during the structural transition upon a small substitution in the cobalt subsystem.

In Gd microwires obtained by ultrafast cooling of the melt, a change in the magnetic entropy of 12 J/kg K was determined at a Curie temperature of 293 K in a magnetic field of 5 T. This value coincides with the change in the magnetic part of the entropy in bulk single-crystal samples in the same field. It has been found that in a strong magnetic field of 9 T, the temperature dependence of the entropy exhibits two maxima at temperatures of 292 and 312 K. The appearance of an additional entropy maximum in microstructured samples is caused by high mechanical microstresses retained in the sample after ultrafast cooling.

For high-strength titanium VT1-0, the ultrafine-grained structure of which was obtained by mechanical-thermal treatment using the methods of helical and longitudinal rolling followed by annealing to relieve stress of the first kind. The effect of long - term loading in the creep mode at elevated temperature on the size and shape of grains has been studied. A similar study was previously carried out for recrystallized coarse-grained titanium transferred from the ultrafine-grained state by isothermal annealing. Based on the data obtained in the work and the previous results of the authors, the factors affecting the mechanical stability (durability) of ultrafine-grained metals obtained under severe plastic deformation were analyzed.

During annealing in the presence of oxygen, this metal is oxidized with the reduction of the second metal, which leads to the formation of nanoparticles embedded in the oxide of the first metal. This the process has been experimentally and theoretically studied by the example of the formation of cobalt nanoparticles on the surface of amorphous Co-Zr-O films as a result of the decomposition of a supersaturated solid solution and mechanical stresses arising during the oxidation of zirconium. We have proposed a mechanism for the formation of catalyst nanoparticles and phenomenological model of this process developed on the basis of the phase-field theory.

Within the framework of the Hubbard model, the energy spectra of the Cs and C3v isomers of C58 fullerene and dimers based on them are calculated. The obtained curves of the density of electronic states of these systems are compared with the experimental curves of the films, which were obtained by deposition of the Cs and C3v isomers of C58 fullerene on the (1,1,1) gold surface. A comparative analysis of the curves of the density of electronic states shows that in those sites through which a bond is formed between fullerenes, carbon is not in the sp2, but in the sp3 hybridized state.
Integrating Psychosocial Aspects in Digital Solutions
Authors: Spindler Helle
Published: August 2022

Background

The design and development of digital health platforms do not routinely incorporate psychosocial aspects and theory that may increase engagement and motivation for using the digital solution. However, emerging evidence suggests that when integrating both theory and psychosocial aspects in the design process, the resulting digital health platforms may be superior in engaging and motivating patients to use them.

Objective

The objective of our study was to give an overview of how and why integrating psychosocial aspects in digital solutions may be essential to engaging and motivating patients to use digital solutions.

Methods

We conducted a brief narrative review of studies integrating psychosocial aspects and theory in the design and development of digital solutions for telerehabilitation.

Results

In the studies identified, self-determination theory, incorporating the patient’s perspective, and using behavioral or psychological interventions on digital platforms are among some of the theoretical and psychosocial aspects that have already been used to design and develop digital solutions for telerehabilitation.

Conclusions

Based on the literature, it is argued that integrating psychosocial aspects and theory in the design and development of digital solutions for telerehabilitation may result in platforms of increased value to both health providers and patients.
Evaluation of Regression Models for Prediction of Next Glucose Measurement in Hospitalized Patients (Preprint)
Authors: Zale Andrew D. , Abusamaan Mohammed S. , McGready John , Mathioudakis Nestoras
Published: August 2022

BACKGROUND

Continuous glucose monitors (CGM) have shown great promise in improving outpatient blood glucose (BG) control; however, CGMs are not routinely used in the hospital.

OBJECTIVE

The purpose of our study was to evaluate times series analytical approaches for prediction of inpatient BG using only point-of-care and serum glucose observations.

METHODS

Electronic health record data from 184,361 admissions from five Johns Hopkins Health System hospitals were collected from patients who were discharged between January 1, 2015 and May 31, 2019. After excluding BG measurements obtained in quick succession or from critically ill patients, there were 2,436,226 BG observations included. The outcome of interest was the next BG measurement (mg/dL). Multiple time series predictors were created and then analyzed using different machine learning techniques.

RESULTS

When analyzing time series predictors independently, increasing variability in a patient’s BG decreased predictive accuracy. Likewise, inclusion of older BG measurements decreased predictive accuracy. When non-glycemic clinical predictors were added to machine learning algorithms, there was generally minimal improvement in predictive accuracy.

CONCLUSIONS

The most recent BG measurement holds more predictive value than the moving average or trend of a patient’s previous BG measurements. These relationships become less strong as glucose variability increases. Further studies should determine the potential of using time series analyses for prediction of inpatient hypoglycemia and hyperglycemia.

Published: August 2022

BACKGROUND

Electronic devices such as computers, smartphones and tablets has become an indispensable part of our daily lives. The frequency and duration of device use in adolescents have increased drastically over the years and the study of its negative musculoskeletal, visual and psychosocial health impacts is necessary.

OBJECTIVE

This cross-sectional study aimed to evaluate the associations between electronic device use and the prevalence and severity of musculoskeletal symptoms, visual symptoms, psychosocial health, and quality of life in adolescents studying at primary and secondary schools.

METHODS

Data were collected through confidential online and paper-and-pencil questionnaires. Primary 4-5 and Secondary 1-4 students were recruited from 3 schools in Hong Kong. Demographics, frequency and duration of electronic device use, frequencies of musculoskeletal symptoms, visual symptoms, psychosocial health, and quality of life outcomes were measured.

RESULTS

1,058 adolescents aged 9-17 years participated. Sixty-one percent and 78% of all students spent more than 2 hours per day using electronic devices during school days and weekend/holidays, respectively. Extended electronic device use was associated with increased prevalence and severity of musculoskeletal symptoms (ρ’s=.28-.33, P’s<.001), visual symptoms (ρ’s=.33-.35, P’s<.001), and poorer device use-related psychosocial health (ρ’s=.38-.47, P’s<.001). Secondary school students reported greater device use and severity of symptoms than primary school students.

CONCLUSIONS

Excessive electronic device use was associated with increased prevalence and severity of physical and psychosocial symptoms, and such use is more prevalent in older adolescents. The findings have important health implications for adolescents, suggesting that early intervention is needed to reduce the risk of developing device use-related disorders.

"Muy parecido al infierno": las circunstancias alrededor del movimiento estudiantil guatemalteco en 1968
Authors: Veliz Rodrigo , Loesener Johann
Published: August 2022

Este artículo examina las principales actividades del movimiento estudiantil guatemalteco en 1968. Expone las razones por las que en ese año no existieron grandes movilizaciones en sintonía con lo que sucedía en otras ciudades latinoamericanas y del mundo, debido al contexto de violencia por el que pasaba el país, derivado en parte de la fuerte presencia estudiantil en la política nacional desde inicios de la década y por la agitada vida gremial y las distintas facciones que la componían, su presencia en redes regionales y de organizaciones armadas, y sus acciones antimperialistas que promovían reformas universitarias ese año. El artículo se enmarca en los recientes debates sobre los matices que muestran los movimientos estudiantiles en la Guerra Fría latinoamericana y tiene como bases documentales los archivos de la Asociación de Estudiantes Universitarios y del Consejo Superior Universitario, complementados con entrevistas, folletería y archivos diplomáticos de México y Estados Unidos.
La formación literaria de Pedro Henríquez Ureña en Cuba, 1904-1906
Authors: Mendoza Bolaños Daniel
Published: August 2022

En este artículo se analiza la primera estancia del dominicano Pedro Henríquez Ureña (1884-1946) en Cuba después de su salida de República Dominicana y de su paso por Nueva York. El estudio se enfoca en las actividades formativas que sustentaron su vocación literaria. Las principales fuentes son documentos personales y las publicaciones que realizó en la isla, que incluyen poesías y ensayos, este último género en el que expresaría su percepción sobre la literatura, historia y política, no solo de Cuba, sino de la América Hispánica, objeto de sus futuros trabajos en diversos países del continente. Se muestra también el proceso de la publicación de su primer libro, Ensayos críticos, así como de la recepción que tuvo entre escritores latinoamericanos.
Narrativa Cubana hoy. Protocolos de la crítica literaria en torno a la Generación Cero
Authors: Viera Katia
Published: August 2022

El presente texto se propone ofrecer una primera aproximación a algunas líneas temáticas y a algunos enfoques teóricos que aparecen con mediana recurrencia en los textos críticos producidos alrededor de las narrativas cubanas de la Generación Año Cero en Cuba. Guían el análisis algunas perspectivas metodológicas sustentadas en el estudio de los protocolos de la crítica literaria y sus tres capas simultáneas (teoría; objeto y construcción; y dimensión expositiva y textual) que permitieron reconocer el sistemático diálogo entramado (y entablado) por parte de la crítica literaria, entre literatura y realidad política, económica y cultural en Cuba a partir de los primeros años 2000 hasta la actualidad.

Authors: Murguía-Romero Miguel , Ortiz Enrique , Serrano-Estrada Bernardo , Villaseñor José Luis
Published: August 2022

Databases of biological collections contain fundamental information for the study of biodiversity, hence the importance of their quality, which includes the data on collectors. For this purpose, a list of the main vascular plant collectors in Mexico was constructed to improve the quality of this information. A total of 3.7 million records of vascular plant specimens collected in Mexico were analyzed from the National System of Biodiversity Information (Sistema Nacional de Información sobre Biodiversidad; SNIB) of the Mexican National Commission for the Knowledge and Use of Biodiversity (Comisión Nacional para el Conocimiento y Uso de la Biodiversidad de México; Conabio) and the database of the National Herbarium of Mexico (Herbario Nacional de México; MEXU) of the Institute of Biology at the National Autonomous University of Mexico (UNAM). A “main collector” was considered anyone with 500 or more unique collection numbers in the database. A total of 610 main collectors were identified, who together contributed 83% of the records of vascular plants collected in Mexico, and a standardized list of their names is presented. The list of names of main collectors of vascular plants in Mexico is a useful tool for the cleaning and extraction of information from biodiversity databases.
