Authors: Shirazi Shahrokh , Hoghooghi-Rad Nasser , Madani Rasoul
Published: June 2021

Cystic echinococcosis (CE) is one of the most prevalent zoonotic diseases in some countries in the world. Cystic echinococcosis is considered a neglected disease. This disease increases economic damage via medical costs and loss of human and livestock productivity. The aim of the current study gains a better understanding of the prevalence of CE in sheep. Totally 250 sheep sera were collected. 25 serum samples from newborn lambs were used as negative, and 25 others were obtained from slaughterhouses as positive to infection with CE and 200 unknown sera. Antigen B Isolated from hydatid cysts fluid was used for designing ELISA methods. The first Method used anti-Sheep conjugate (SIGMA, at 1:3000 dilution). According to the results, the seroprevalence of CE in East Azerbaijan of Iran was 5.5% and sensitivity and specificity for the diagnosis of hydatidosis in sheep by AgB-ELISA methods was 92%. Using Antigen B in ELISA design for hydatidosis diagnosis has attracted researchers in recent years. During this study, an Iranian native B antigen was used to design the specific detection of hydatidosis in sheep using a specific ELISA technique. The results have shown that using Antigen B in ELISA design is so valuable.

There is still a long way to go before artificial mini robots are really used for search and rescue missions in disaster-hit areas due to hindrance in power consumption, computation load of the locomotion, and obstacle-avoidance system. Insect–computer hybrid system, which is the fusion of living insect platform and microcontroller, emerges as an alternative solution. This study demonstrates the first-ever insect–computer hybrid system conceived for search and rescue missions, which is capable of autonomous navigation and human presence detection in an unstructured environment. Customized navigation control algorithm utilizing the insect’s intrinsic navigation capability achieved exploration and negotiation of complex terrains. On-board high-accuracy human presence detection using infrared camera was achieved with a custom machine learning model. Low power consumption suggests system suitability for hour-long operations and its potential for realization in real-life missions.

Published: June 2021

Global warming and rising air pollution which has been caused by using too much fossil fuel has led to look for a new clean source, sustainable and eco-friendly of energy like H2, which can be produced by cyanobacteria and microalgae. In this study, Anabaena sp. was used in a continuous operation to achieve biohydrogen production. To this end, an airlift photobioreactor (20 L) was considered. The effects of the gas holdup, liquid circulation velocity, and the amount of dissolved oxygen on hydrogen production were investigated. Gas holdup, liquid circulation velocity, and KLa (mass transfer coefficient) showed an upward trend by increasing the velocity of the inlet gas. Maximum biomass concentration of and maximal H2 production were observed 1.2 g L-1 d-1 and 371 mL h-1 PBR-1, respectively under light intensity of 3500 lux/m2 applying a light-dark cycle in 7 days, at Ad/Ar of 1.25 and 0.185 and 0.542 cm/s. pH, temperature (30+2 °C), light intensity, and inlet gas flow to the bioreactor (containing 98% air and 2% carbon dioxide) were remained steady. Using the airlift photobioreactor with a good mass transfer and light availability to cyanobacteria growth can be a cost-effective and environmentally technology for biological H2 production.

Published: June 2021

BackgroundAlthough increasing cerebral perfusion pressure (CPP) is commonly accepted to improve brain tissue oxygen pressure (PbtO2), it remains unclear whether recommended CPP targets (i.e. > 60 mmHg) would result in adequate brain oxygenation in brain injured patients. The aim of this study was to identify the target of CPP associated with normal brain oxygenation. MethodsProspectively collected data including patients suffering from acute brain injury and monitored with PbtO2, in whom daily CPP challenge using vasopressors was performed. Initial CPP targets were >60 mmHg; norepinephrine infusion was modified to have an increase in CPP of at least 10 mmHg at two different steps above the baseline values. Whenever possible, the same CPP challenge was performed for the following days, for a maximum of 5 days. CPP “responders” were patients with a relative increase in PbtO2 from baseline values >20%.ResultsA total of 53 patients were included. On the first day of assessment, CPP was progressively increased from 73 [70-76] to 83 [80-86] and 92 [90-96] mmHg, which resulted into a significant PbtO2 increase (from 20 [17-23] mmHg to 22 [20-24] mmHg and 24 [22-26] mmHg, respectively; p<0.001). Median CPP value corresponding to PbtO2 values > 20 mmHg was 79 [74-87] mmHg, with 2 (4%) patients who never achieved such target. Similar results of CPP targets were observed the following days. A total of 25 (47%) were PbtO2 responders during the CPP challenge on day 1, in particular if low PbtO2 was observed at baseline. ConclusionsPbtO2 monitoring can be an effective way to individualize CPP values to avoid tissue hypoxia. Low PbtO2 values at baseline can identify the responders to the CPP challenge.

Published: June 2021

As the photovoltaic performance of mesoscopic perovskite solar cells (PSCs) is strongly dependent on the interface between perovskite and electron transport layer. Herein, an attempt to load facile processed ZnO quantum dots (ZQDs) or TiO2 quantum dots (TQDs) into the mp-TiO2 layer via a simple spin-coating method was first performed. Both of them had huge impact on the morphology of perovskite films, leading to larger perovskite grains. However, the power conversion efficiency (PCE) of these two kinds of QDs modified cells exhibited a different tendency. The champion PCE of ZQDs modified PSCs was remarkably improved from 14.54% to 17.2%, while that of TQDs modified ones decreased to 11.78%. We demonstrated that the enhanced PCE and short-circuit current (Jsc) were attributed to the enlarged grain size and enhanced light absorption of perovskite film, faster electron extraction and transport as well as less recombination for ZQDs modified PSCs, which mainly resulted from the increased active specific surface area. On the contrary, deterioration of TQDs modified PSCs was exactly ascribed to the aggregation of TQDs which sharply decreased the specific surface area of the electron transport layer. The current work provided an efficient and facile way to improve the photovoltaic performance of mesoscopic PSCs.

Published: June 2021

Background: Exogenous exposure to cadmium is associated with cardiovascular diseases, including atherosclerosis, but experimental evidence elucidating the molecular events involved is still unclear, hence this study. We investigated whether sub-chronic cadmium exposure alone could cause a disruption in lipid and glucose metabolisms and whether the combined effect of these dysregulations could progressively lead to atherosclerosis in ApoE (-/-) mice.Methods: Experiments were performed in male ApoE (-/-) mice (8 weeks 25 ± 3g; n=60), which were randomly placed into four (4) groups according to body weight and administered cadmium (CdCl2) 0, 50, 100 and 200 mg/L, respectively in drinking water consecutively for 4 months. After treatment, changes in body weight were evaluated and mice plasma was analyzed for LDL, HDL, TCHO, TG, insulin and glucose levels. The collected samples were sent for histological examination in the 4th month and two-way ANOVA was used for statistical analysis.Results Levels of plasma LDL increased in all treatment groups but was statistically significant in the 4th month across all treatment groups when compared both with the blank control group and the first month mice. Plasma HDL levels were lowered in all treatment groups in the 2nd and 4th months when compared with the 1st month mice. Statistically significant decreases in plasma HDL levels were also observed in the 2nd month in the group receiving CdCl2 (100mg/L and 200mg/L) when compared with the blank control. TCHO andTG levels increased but was statistically significant in the former in the 1st, 2nd and 4th month at CdCl2 (100mg/L and 200mg/L) and in the latter at the same dose only in the 4th month. Moreover, fasting plasma glucose and insulin were elevated and lowered, respectively. Histological examination of aortal root also showed a dose-dependent increase in plaque formation, being most visible in the treatment group receiving CdCl2 (200mg/L).Conclusion: In line with our hypothesis, sub-chronic oral exposure of ApoE (-/-) mice to cadmium dysregulated their glucose and lipid profiles and the combined effect of this may be a contributory molecular event in the development of atherosclerosis.

Published: June 2021

In September 2020, samples of galled roots with rhizosphere soil were collected from declining Gentiana macrophylla in Yulong County, China. The pathogenic nematodes were identified by observing morphological characteristics of females, second-stage juveniles and perineal pattern, sequence alignments, and specific amplification of sequence characterized amplified region (SCAR). The results showed that the perineal pattern of this nematode was round or oval, the dorsal arch was moderately high or low, one side or both of the lateral field extended to form a wing shape, the tail region had punctations, and the morphological characteristics and morphometric values of second-stage juveniles and females were similar to those of Meloidogyne hapla. The ITS region fragment of this nematode were highly similar to those of M. hapla in NCBI database, with a similarity of over 99.35%. Using the SCAR specific primers, a specific band with an expected size of approximately 440 bp was amplified from this nematode. Morphological and molecular identification supports the nematode species found on Gentiana macrophylla as M. hapla. This is the first report of this regulated root-knot nematode on Gentiana macrophylla in China.

Patients with comorbidities including Hypertension (HTN), Diabetes Mellitus (DM), Chronic Obstructive Pulmonary Disease (COPD), Asthma, Obesity, Cardiovascular Disease (CVD), Chronic Kidney Disease (CKD), and those who are immunocompromised are prone to more severe complications of COVID-19 and a higher rate of hospitalizations. In the United States, around 94% of COVID-19 deaths had an average of 2.6 additional conditions or causes per death. In a summary report published by the Chinese Centre for Disease Control and Prevention of 72,314 cases, case-fatality rate was elevated among those with preexisting comorbid conditions—10.5% for cardiovascular disease, 7.3% for diabetes, 6.3% for chronic respiratory disease, 6.0% for HTN, and 5.6% for cancer. The COVID-19 pandemic continues to threaten people and healthcare systems globally and therefore the global economy. Currently, there is no cure or vaccine for COVID-19 and there is an urgent need to develop target therapies as we continue to learn more about this novel virus. Without therapeutic interventions, much of how we contain the viral spread is prevention through mitigation strategies (social distancing, face masks, supportive care). Early suspicion of COVID-19 symptoms with radiological and laboratory assessments may play a major role in preventing severity of the COVID-19. With this literature review we aim to provide review of pathophysiology of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) and its clinical effects on multiple organ systems.

Published: June 2021

Climate change affects the water cycle in different regions. The response of annual runoff and seasonal distribution to climate change in the upper reaches of the Minjiang River during 2021–2050 was studied by coupling the Statistical Downscaling Model (SDSM) and the Soil and Water Assessment Tool (SWAT). This model was driven by the second-generation Canadian Earth System Model (CanESM2) under RCP2.6, RCP4.5, and RCP8.5 scenarios. The results show that the runoff in the upper reaches of the Minjiang River has a unique response to climate change. The maximum and minimum temperatures will increase with the increase in emissions, especially in December–January. The daily precipitation shows an upward trend, especially in July–August in the RCP4.5 scenario. The annual runoff shows an upward trend with the increase in emissions. Compared with the current increase of 13–26%, the most prominent period is November–April. Because the study area covers high mountains and gorge landforms, the altitude difference is great, and the influence of evapotranspiration and snow melting processes is more prominent, causing the monthly runoff to decrease in June–July with an increase in precipitation. From April to May, precipitation decreased while runoff increased.
Identifying most promising agronomic adaptation strategies to close rainfed rice yield gap in future: a model-based assessment
Authors: Debnath Subhankar , Mishra Ashok , Mailapalli D. R. , Raghuwanshi N. S.
Published: June 2021

There is an increasing consensus that climate change may have a high negative impact on crop yield, and that it will affect farmers in developing and least developed counties the most. ‘Closing the yield gap’ could be one of the promising options to address the issue of yield improvement. Better understanding of adaptation strategies and implications of the adaptations in crop yield are required to close the yield gap. In this study, the effectiveness of agronomic adaptation options on the rainfed rice yield gap was evaluated for the baseline period (1981–2005) and two future periods (2016–2040 and 2026–2050) for India by using bias-corrected RegCM4 output and the Decision Support System for Agrotechnology Transfer (DSSAT) model. Results suggested that a combined adjustment of transplanting time (advancing by fortnight), crop spacing ((10 × 10) cm) and N-fertilizer application (140 kg/ha) was the best strategy as compared to the single adaptation option to close the yield gap under the climate change scenario. The strategy improved rice yield by 37.5–168.0% and reduced the average attainable yield gap among the cultivars from 0.74 to 0.16 t/ha under future climate projection. This study provides agronomic indications to rice growers and lays the basis for an economic analysis to support policy-makers in charge of promoting the sustainability of the rainfed rice-growing systems.

Authors: Fan Guangli , Sarabandi Amjad , Yaghoobzadeh Mostafa
Published: June 2021

In this study, the trend of climate changes during a future period from 2020 to 2039 has been evaluated using the data of the Fifth Climate Change Report under two emission scenarios RCP 4.5 and RCP 8.5 for Neishabour plain, Iran. The 11 models of CESM, EC EARTH, HADGEM, MPI, NORESM, CANESM, CSIROM, GFDLCM2, GISS E2, IPSL and MIROC ESM have been used to evaluate changes in minimum and maximum temperatures, precipitation, and evapotranspiration. The results showed that the GFDLCM2, MPI and IPSL models were more accurate in terms of precipitation and the GISS E2 and GFDLCM2 models were the suitable option for predicting the maximum and minimum temperatures and evapotranspiration. Considering the evaluated parameters, minimum temperature, maximum temperature and evapotranspiration had approximately constant trends and were accompanied by a slight increase and decrease for the next two decades, but for the precipitation, large fluctuations were predicted for the next period. Moreover, in the study years for the four parameters in all simulated models, the RCP 8.5 scenario estimated a higher amount than the RCP 4.5 scenario.

Published: June 2021

The evaluation of groundwater quality and geochemistry have an important role in the management of water resources in arid and semi-arid regions. In the present study, the spatio-temporal assessment of groundwater quality and hydrogeochemical processes, as well as, statistical analyses in the Azarshahr and Ajabshir plains located in the Urmia Lake basin were investigated. The results revealed that within six years (from 2014 to 2019), the value of total hardness was higher than the permissible level and the quality of groundwater for drinking was very hard and fresh in both plains. In 2019, 84 and 67% of the samples fell within the range of good to poor groundwater quality in the Azarshahr and Ajabshir plains, respectively. The temporal assessment with the help of water quality index values for both plains revealed a good groundwater quality for the Azarshahr plain and a good to poor groundwater quality for the Ajabshir plain. However, deterioration of water quality was observed in both plains from 2014 to 2019. The level of water quality for irrigation was better in the Azarshahr plain than in the Ajabshir plain, due to the presence of fewer salty sites. In addition, Ca–Mg–HCO3 and rock dominance were identified as hydrochemical facies and the controlling factor in the groundwater of both plains, respectively. Multivariate statistical analyses indicated both natural and anthropogenic sources (such as weathering, fertilizers, and wastewater) for hydrochemical parameters. It was suggested to develop a comprehensive regulation to control the entry of pollutants into the groundwater of the study area.

Evaluation of a Parsimonious COVID-19 Outbreak Prediction Model: Heuristic Modeling Approach Using Publicly Available Data Sets
Authors: Gupta Agrayan K , Grannis Shaun J , Kasthurirathne Suranga N
Published: June 2021

Background

The COVID-19 pandemic has changed public health policies and human and community behaviors through lockdowns and mandates. Governments are rapidly evolving policies to increase hospital capacity and supply personal protective equipment and other equipment to mitigate disease spread in affected regions. Current models that predict COVID-19 case counts and spread are complex by nature and offer limited explainability and generalizability. This has highlighted the need for accurate and robust outbreak prediction models that balance model parsimony and performance.

Objective

We sought to leverage readily accessible data sets extracted from multiple states to train and evaluate a parsimonious predictive model capable of identifying county-level risk of COVID-19 outbreaks on a day-to-day basis.

Methods

Our modeling approach leveraged the following data inputs: COVID-19 case counts per county per day and county populations. We developed an outbreak gold standard across California, Indiana, and Iowa. The model utilized a per capita running 7-day sum of the case counts per county per day and the mean cumulative case count to develop baseline values. The model was trained with data recorded between March 1 and August 31, 2020, and tested on data recorded between September 1 and October 31, 2020.

Results

The model reported sensitivities of 81%, 92%, and 90% for California, Indiana, and Iowa, respectively. The precision in each state was above 85% while specificity and accuracy scores were generally >95%.

Conclusions

Our parsimonious model provides a generalizable and simple alternative approach to outbreak prediction. This methodology can be applied to diverse regions to help state officials and hospitals with resource allocation and to guide risk management, community education, and mitigation strategies.
The Potential of Digital Symptom-based Screening to Reduce the Transmission of SARS-CoV-2: a Modelling Study (Preprint)
Authors: Multmeier Jan , Montazeri Maryam , Vona Nicola , Bergey François , Mehl Alicia , Gilsdorf Andreas
Published: June 2021

BACKGROUND

Early efforts to control the COVID-19 pandemic have been focused on Non-Pharmaceutical Interventions (NPIs) in the absence of effective treatments or sufficient vaccine supply. While retrospective analyses and modeling studies confirmed that severe restrictions of social contacts, i.e., lockdowns, are most effective in reducing transmission of SARS-CoV-2, they incur large economic costs and mental health risks. Earlier detection of cases has also been proposed as an effective method of control, but studies have so far only considered enhanced laboratory testing. Digital applications have been developed which aim to identify possible cases of COVID-19 based on reported symptoms and risk factors.

OBJECTIVE

The aim of this study is to explore the effects of digital screening applications for COVID-19 on the transmission of SARS-CoV-2.

METHODS

Using an established epidemiological Susceptible-Exposed-Infectious-Recovered (SEIR) model for infectious disease transmission, we simulate the transmission of SARS-CoV-2 in Germany, the UK, and the USA for 366 days after the virus was introduced in the population. We study 4 scenarios: 1) no interventions (base case), 2) symptom-based self-isolation after consulting healthcare providers, 3) self-isolation using digital screening applications, and 4) severe social contact limitations (lockdown). We included sensitivity analyses for different ratios of infectiousness of pre-symptomatic cases compared to symptomatic cases, and different rates of adoption of digital screening tools.

RESULTS

Without any intervention, 74% of the German population would be infected with SARS-CoV-2 within the simulation period (UK: 76%, USA: 77%). Self-isolation of symptomatic cases would already slow the spread of the virus significantly and lead to only 18% of the German population being infected (UK: 17%, USA: 17%). Using a digital application could further reduce the infected population to 10% (UK: 9%, USA: 9%), compared to 3% under lockdown conditions. While the effectiveness of digital screening applications varies with the adoption rate, even a low adoption rate could significantly reduce transmission. In the case that pre-symptomatic cases are less infectious than symptomatic cases, the overall proportion of infected individuals in the population decreases, and the effectiveness of different interventions converges.

CONCLUSIONS

Digital symptom-based screening tools can substantially impact the transmission of SARS-CoV-2 and might be a viable element in strategies to control COVID-19 through NPIs.

Increasing root penetration into a different environment is more important than improving rooting depth
Authors: Gong Xue , Taylor Julian , McDonald Glenn
Published: June 2021

Deep rooting is often thought as a promising phenotype for resource
extraction, but on soils with constraints, desired rooting depth was
rarely observed. We hypothesised that if the genetic effect on root
growth and rooting depth were separated from other effects, the
determinants of root growth and rooting depth could be quantified. The
conventional core-breaking method was used to measure root growth of
wheat at two sites in two successive years under rain fed conditions.
The Bayesian hierarchical nonlinear mixed models (HNLMMs) were employed
to estimate root distribution, heritability and rooting depth. We found
that root penetration from the non-sodic top to the sodic subsoil was
most critical in determining rooting depth. Our study indicates that
focusing on root-soil interaction at the transition layer where soil
constraints start to emerge would lead to a more effective solution to
develop resilient roots. Our work not only serves as a guide for
selecting genotypes in pot trials, but also provides a theoretical
support to breed advance crops with better soil adaptation.

Combining mercapto-functionalized palygorskite with zinc affect cadmium phytoavailability and soil microbial activity in rhizosphere soil
Authors: Li Yulong , Gao Chao , Rong Sashuang , Gu Jialin , Zhao Huiwei , Su Shiming , liu wei
Published: June 2021

Cadmium (Cd) pollution in soil pose a grave threat to human health.
Combining various approaches to reduce Cd accumulation in crops is an
active area of research to remediate farmlands with medium-high levels
of Cd contamination. The Mercapto-functionalized palygorskite (PGS-SH)
and zinc (Zn) application alone or in combination was investigated to
explore reduction of Cd uptake in B. chinensis L and transformation of
Cd in soil. The sole application of Zn or PGS-SH increased the biomass
of B. chinensis L. and decreased the concentration of Cd in plants, but
more improvements were observed from the combined application of Zn and
PGS-SH. Low concentration of exogenous Zn (50 mg/kg) significantly
increased the soil respiration rate (SRR) and the soil dehydrogenase
activity (sDHA), while promoted B. chinensis L. growth while inhibiting
Cd uptake. However, excessive exogenous Zn (≥ 200 mg/kg) significantly
inhibited B. chinensis L. growth and soil microbial activity. The
combined application of PGS-SH and Zn had the highest sDHA (145.59%)
and lowest transport factor (TF) (27.59%) compared with the CK. The

We describe a case of frozen elephant trunk deployment unintentionally
malpositioned into the false lumen. An 83-year-old man underwent total
arch repair with a frozen elephant trunk for type A acute aortic
dissection complicated by mesenteric malperfusion. However,
intraoperative transesophageal echocardiography showed expansion of the
false lumen in the descending aorta, suggesting a malpositioned frozen
elephant trunk into the false lumen. Endovascular fenestration of the
dissecting flap and subsequent endograft deployment from the inside of
the malpositioned frozen elephant trunk graft to the true lumen of the
descending aorta was successfully performed under intravascular
ultrasound guidance.

The actinomycete Lentzea aerocolonigenes produces the antitumor
antibiotic rebeccamycin. In previous studies the rebeccamycin production
was significantly increased by the addition of glass beads during
cultivation in different diameters between 0.5 – 2 mm and the induced
mechanical stress by the glass beads was proposed to be responsible for
the increased production. Thus, this study was conducted to be a
systematic investigation of different parameters for macroparticle
addition, such as bead diameter, concentration and density (glass and
ceramic) as well as shaking frequency, for a better understanding of the
particle induced stress on L. aerocolonigenes. The induced stress for
optimal rebeccamycin production can be estimated by a combination of
stress energy and stress frequency. In addition, the
macroparticle-enhanced cultivation of L. aerocolonigenes was combined
with soy lecithin addition to further increase the rebeccamycin
concentration. With 100 g L glass beads in a
diameter of 969 µm and 5 g L soy lecithin a
concentration of 388 mg L 1 rebeccamycin was reached after 10 days of
cultivation, which corresponds to the highest rebeccamycin
concentrations achieved in shake flask cultivations of L.
aerocolonigenes stated in literature so far.

Exact nonlinear partial differential equation solutions are critical for
describing new complex characteristics in a variety of fields of applied
science. The aim of this research is to use the F-expansion method to
find the generalized solitary wave solution of the regularized long wave
(RLW) equation of fractional order. Fractional partial differential
equations can also be transformed into ordinary differential equations
using fractional complex transformation and the properties of the
modified Riemann–Liouville fractional-order operator. Because of the
chain rule and the derivative of composite functions, nonlinear
fractional differential equations (NLFDEs) can be converted to ordinary
differential equations. We have investigated various set of explicit
solutions with some free parameters using this approach. The solitary
wave solutions are derived from the moving wave solutions when the
parameters are set to special values. Our findings show that this
approach is a very active and straightforward way of formulating exact
solutions to nonlinear evolution equations that arise in mathematical
physics and engineering. It is anticipated that this research will
provide insight and knowledge into the implementation of novel methods
for solving wave equations.
El impacto de las reformas a la ley del trabajo sobre la calidad de vida de los trabajadores

Introducción: En la década de los años setenta se consideró al neoliberalismo como la respuesta para paliar los problemas económicos mundiales, el cual pugnaba por la disolución progresiva de las fronteras económicas y políticas. Se pensaba que el libre flujo de dinero desde los países ricos en la región de Europa y Norteamérica hacia las vastas regiones pobres de África, América Latina y Oceanía era suficiente como estrategia para eliminar la pobreza y acabar con las crisis económicas recurrentes. A la par se desarrolla la globalización como un proceso de integración de todas las comunidades alrededor del mundo en los ámbitos económico, político, tecnológico, social y cultural, logrado por el desarrollo sin precedentes de los sistemas de comunicación. Este avance tecnológico favoreció el intercambio de productos y servicios, así como la conexión o movimiento de personas, y facilitó las inversiones y transacciones financieras entre mercados distantes o emergentes, acciones que antiguamente resultaban muy difíciles, altamente costosas o inviables.

La combinación de ambos fenómenos ha modificado la forma en que interactúan los países, las empresas y los individuos, de modo que, en esta última parte, ha impactado directamente en el mercado laboral, que a su vez ha modificado el ámbito jurídico y político de muchas regiones del planeta. Para lograr la competitividad solicitada internacionalmente uno de los factores clave fue la aplicación de modificaciones legislativas en materia laboral. En otras palabras, fue el concepto de flexibilización del empleo la base de modificación de la antigua ley para dejar que las fuerzas del mercado definieran su calidad.

Objetivo: En este estudio se realiza un comparativo entre la Ley Federal del Trabajo vigente en México respecto a la normativa antecesora, para lo cual se tomaron en cuenta el concepto calidad de vida, así como los indicadores propuestos por diferentes entidades internacionales.

Método: Se analizaron los indicadores mencionados bajo un sistema binario de calificación para realizar el acumulado (indicador acumulativo), elemento de comparación. La innovación de esta tarea fue la calificación de cada artículo de la ley en función de los conceptos calidad de vida y bienestar tipificados por las entidades internacionales. Esta propuesta de evaluación de las condiciones laborales de los trabajadores en México se considera más objetiva al abordar el bienestar material, los elementos de seguridad social y de realización personal.

Resultados y conclusiones: Se identifica una pérdida de elementos relacionados con la seguridad alimentaria, acceso a salud y educación, así como un retroceso en materia de seguridad laboral según los indicadores internacionales, lo que genera una precariedad laboral. Esto, en términos de desarrollo, constituye un retroceso en cuanto a las características del concepto bienestar.
