Unequal and Divided The Middle Classes in Contemporary Brazil
Authors: Costa Sérgio
Published: April 2023

The middle class, or rather middle classes, to do justice to their heterogeneity, have been and continue to be at the centre of the long political and economic crisis that has been ravaging Brazil since 2014. Available interpretations that try to explain the positions taken by different political authors are biased by structural, ideological, or cultural determinism. To escape these determinisms, I draw on Stuart Hall’s political sociology in order to understand the link between the class situation of the middle classes and their constitution as political subjects of various shades as contingent intersectional articulations. The emphasis on contingency obviously does not imply a belief that political developments are fortuitous and detached from social structures. Nor does it ignore the existence of groups with deeply held ideological or cultural convictions who consistently adopt, over long periods of time, political attitudes compatible with these beliefs. However, taken as a whole, the middle classes have shown a very heterogeneous and changing political trajectory over time. They adhere to discourses - both right-wing or more egalitarian ones - and make political choices based on the power of these narratives to capture, in given circumstances, their anxieties, expectations, claims and aspirations.
El proceso de polarización en América Latina Entre la secularización y el conflicto distributivo
Authors: Kessler Gabriel , Vommaro Gabriel , Assusa Gonzalo
Published: April 2023

América Latina vive actualmente un proceso de polarización en muchos países que constituye sin lugar a dudas un reto para incrementar los rasgos más cohesivos de la convivialidad. ¿Cómo actúan los factores económico-distributivos y culturalesmorales en los escenarios actuales de polarización? En este paper mostramos, primero, que el proceso general de secularización está extendido en la mayor parte de los países estudiados, aunque persisten segmentos conservadores resilientes y muy activos. Segundo, que los issues culturales-morales adquieren saliencia en conflictos polarizados en virtud de la relación entre la aceleración de los cambios en las posiciones en temas culturales (secularización acelerada) y la acción de variables asociadas con la politización de estos issues: ideología y religión. Tercero, que los issues económico-distributivos siguen estructurando preferencias políticas y se mantienen como escenario de polarización en América Latina, aunque las posiciones en este campo son menos consistentes y correlacionan más con la clase que con la ideología. Nuestro paper estudia los casos de Argentina, Brasil, Colombia y México, que reúnen el 80 % de la población del continente. Se apoya en un análisis de las series históricas (desde los años 1980 hasta la actualidad) de la encuesta World Values Survey e incorpora datos provenientes de un estudio comparado basado en grupos focales.

The present paper is essentially a case study in the history of philosophy. Its main task is to describe the life and work of theorist whose lifetime work was rather largely omitted in Czech-Slovakian learned community: Anglo-American mathematician, physicist and philosopher Alfred North Whitehead. His life-story is sometimes abbreviated as a „story of three cities“: Cambridge (England), London and Cambridge (Massachusetts). The paper is focusing on some important moments in philosopher’s life (his education and maturation, his religious development) and tries to emphasize them as a key issues to understand his lifetime project. At the very end some remarks concerning the reception of Whiteheads thoughts in Czech-Slovakian milieu are added.
Základ všeho vědosloví J. G. Fichta: Založení vědy jako sebezaložení člověka
Authors: Zika Richard
Published: April 2023

The effort of Fichte’s Foundations of the Entire Science of Knowledge is to ground the whole of the science in so called principles. This aim is a specific expression of the project of self-assurance of human being characterizing the important movement of modern metaphysics. The movement towards self-assurance even culminates here: it gets a form of showing human being as an entity founding (or producing) itself and in totality with itself the whole of (experienced) actuality. The foundation of science is therefore in this Fichte’s work completely subordinated to the project of explicit self-constitution of human being based in practical-theoretical mastering of consciousness of its own ontological-ontical priority.
Claude Lévi-Strauss: překonat okouzlení
Authors: Paleček Martin
Published: April 2023

When we consider which kind of theory we should apply to a given problem, one of the most important criteria is the effect of its application. In other words: we evaluate theories in terms of their abilities to solve problems. In this essay I would like to indicate which kinds of problems are crucial for social sciences and illustrate these problems by means of the structuralist criticism of functionalism. I argue that the Levi-Strauss’ proclamations about his method have never been fulfilled and that the structural anthropology is not satisfactory.

Abundance and sighting patterns of bottlenose dolphins (Tursiops truncatus) at four northwest Atlantic coastal sites

Published: April 2023

Researchers and managers studying Atlantic coastal bottlenose dolphins along the east coast of the United States have been working on the hypothesis that there are two units within the population. One unit migrates seasonally along the northwest Atlantic coast (moving north during summer and south during autumn and winter), while the other remains in local inshore waters year-round. As part of independent, on-going studies begun in the late 1980s and mid-1990s, the occurrence of dolphins was compared among four separate sites (Virginia, North Carolina, South Carolina and Florida) in 1997. The goals of the study were to test the current working hypothesis of one migrating stock of dolphins using data on abundance, distribution and sighting patterns and to calculate a minimum estimate of the population size of northwest Atlantic coastal bottlenose dolphins at the four sites. Dolphins were consistently present in Virginia from April to October and year-round in North Carolina, South Carolina and Florida. In total, 7,830 dolphins were counted and 2,839 identifications were made. Monthly dolphin counts and water temperatures were positively correlated at the Virginia, South Carolina and Florida sites. After adjusting for effort, monthly dolphin counts were significantly different among the four sites but new identification rates were not. The monthly resighting rates were significantly higher in Florida than at the other sites. Based on mark-recapture analysis, it was estimated that 2,392 coastal bottlenose dolphins were present at the four sites in 1997. This estimate is similar to published abundance estimates for dolphins along the entire US Atlantic coast (2,482). These results support the hypothesis of multiple population units with distinct movement patterns and suggest that published abundance estimates for coastal bottlenose dolphins are greatly underestimated.
Early descriptions of whales
Authors: Robineau Daniel , Buffrenil Vivian de
Published: April 2023

Many of the early descriptions of whales and their behaviour and ecology were published in languages other than English. These were often sections in books or articles that were more broad in scope, for example general works on zoology or geography. If translations into English exist at all, they are often not precise with respect to the cetacean component. The Journal invites submissions of such descriptions. Submissions should include: full bibliographic information; a brief introduction to the author and the work in which the description is included; the full text in the original language; and a careful translation.
Current knowledge of the cetacean fauna of the Greek Seas
Authors: Frantzis A. , Alexiadou P. , Paximadis G. , Politi E. , Gannier A. , Corsini-Foka M.
Published: April 2023

From 1991-2002 data on the presence and distribution of cetaceans in the Greek Seas have been systematically collated in a database (821 sightings and 715 strandings). Data originated from dedicated surveys, stranding reports, opportunistic sightings and published or unpublished photographic and video documents. Twelve cetacean species have been recorded. Seven of them are permanently present and commonly observed in one or more of the Greek Seas: striped dolphin, common bottlenose dolphin, short-beaked common dolphin, Cuvier’s beaked whale, sperm whale, Risso’s dolphin and fin whale. In addition, the harbour porpoise is present locally in the Thracian and northern Aegean Seas. The humpback whale, false killer whale and common minke whale are occasional Mediterranean species that were sighted or stranded infrequently; the Sowerby’s beaked whale is an accidental species that was found floating dead only once. Five other species (white whale, Blainville’s beaked whale, long-finned pilot whale, killer whale, blue whale) have been erroneously included in the Greek cetacean fauna in the past due to wrong assumptions, false identifications or lack of supporting evidence. The occasional occurrence of pilot and killer whales in the Greek Seas should still be regarded as unconfirmed. The distributional range, stranding numbers and sighting frequencies of sperm whales, Cuvier’s beaked whales and short-beaked common dolphins in the Greek Seas indicate that their local ‘sub-populations’ are among the most important in the entire Mediterranean Sea. Harbour porpoises in the Thracian and northern Aegean Seas are important from a conservation perspective since this species does not inhabit any other part of the Mediterranean Sea.
Inshore-offshore movements of two fin whales (Balaenoptera physalus) tracked by satellite off West Greenland
Authors: Heide-Jørgensen M. P. , Witting L. , Jensen M. V.
Published: April 2023

Two fin whales (Balaenoptera physalus) were tagged with satellite linked radio transmitters in a costal area near Aasiaat in West Greenland and tracked for 76 and 32 days in 2000 and 2001 respectively. In 2000, one whale was tagged on 30 September; it stayed in the tagging area until at least 13 October. On 16 and 17 October it was found further south off the coast of West Greenland. On 20 October it had moved approximately 250km southeast to another inshore area. It moved another 100km south along the coast and up to 50km off the coast until 2 November, then appeared back in the area it was located on 20 October until contact was lost on 20 December. In 2001, one whale was tagged on 24 August, it stayed in the coastal area until mid September, where it travelled south along the coast to an area approximately 100km off the coast. From here it continued south to the same inshore area occupied by the whale in 2000. It remained in this area until the last position was received on 25 September. The tracking data suggest a connection between inshore and offshore ( > 22km) fin whales and indicates the potential range of fin whales in West Greenland.
A review of bowhead whale (Balaena mysticetus) stock identity
Authors: Rugh David , Demaster Douglas , Rooney Alejandro , Breiwick Jeff , Shelden Kim , Moore Sue
Published: April 2023

For management purposes, the Scientific Committee of the International Whaling Commission has considered bowhead whales as having five stocks (geographically distinct segments of the population): Spitsbergen, Davis Strait, Hudson Bay, Okhotsk Sea and Bering-Chukchi-Beaufort Seas (B-C-B). These divisions are defined primarily by known distribution and seasonal movements. Historically, bowhead whales had a circumarctic distribution, with several periods of range expansion and contraction depending upon access through Arctic straits. Heavy exploitation by pre-20th century commercial whalers reduced bowhead whale abundance, further segregating stocks. A portion of the B-C-B stock escaped whalers by migrating into the pack ice each spring and summering in the Beaufort Sea. Few bowhead whales are now found in the summer in the Chukchi or Bering Seas. The distribution of this species should be considered labile, affected by sea ice and availability of prey, a factor that improves the likelihood of genetic mixing between stocks. Genetic variability has remained relatively high in spite of the severe depletion of the population, and there is no evidence of any recent genetic bottleneck. Besides geographic distribution and genetics, stock identity may be studied via morphological differences, reidentification of individuals between different stock areas, acoustic signatures, pollutant burdens, parasites and predators, feeding ecology and conception dates. Harpoon heads, research tags and lens racemisation indicate that bowhead whales are long-lived, can travel over large areas and may mix among stocks. Because conception occurs during or near the time of the spring migration, there are opportunities for genetic mixing among whales that might use different summering areas.

Published: April 2023

The Eastern North Pacific gray whale (Eschrichtius robustus) is one population of large cetacean that has recovered from depletion resulting from commercial harvest in the mid- to late-1800s. It is believed that this population may be approaching, or possibly exceeding its carrying capacity as suggested by recent increases in mortality of all age and sex classes. Research on the breeding biology and phenology of gray whales that spend the winter in the coastal waters and lagoons of Baja California, Mexico has been conducted for many years. These studies contribute valuable information on the reproductive biology of this species, and the importance of their coastal lagoon habitats to their reproductive success. This paper reviews and summarises historical exploitation, conservation measures, the findings of research conducted on gray whales in their winter breeding range, potential natural and anthropogenic threats to this population, and makes recommendations for future research and monitoring. This review concentrates on the findings of research conducted since the mid-1970s.

Alzheimer’s disease (AD) is a brain disorder which is irreversible as well as progressive. AD slowly destroys memory and thinking skills. The most common cause of Dementia is AD. Dementia that consists of (loss of Cognitive functioning – thinking, remembering and reasoning – and behavioural ability) is caused due to death of neurons due to AD, it has serious interference with Daily life. The chronicity of the disease is increasing rapidly in the world. The advancements in medical have initiated many research studies to automatically detect the disease by capturing the brain signals. The main aim of this paper is to help the doctors detect the Alzheimer’s disease at earliest and more number of patients can be prevented before irreversible changes occur in brain. In this paper we present some common features that will improve the detection of AD accurately from EEG signals in early stage of the disease. Apart from this, different signal decomposition methods including filtering into brain frequency bands, discrete wavelet transform (DWT) and empirical mode decomposition (EMD), and various classification algorithms including support vector machine (SVM), K-nearest neighbours (KNN) and regularized linear discriminant analysis (RLDA) are evaluated.

In the present work, the catalytic activity and stability of the Fresh-water Clamshells-derived CaO catalyst were investigated by the transesterification reaction of lard oil. The physicochemical properties of lard oil as a raw material for biodiesel production compared with palm oil were also studied. The obtained CaO_FWC was characterized by various analytical techniques to evaluate the physicochemical properties consisting of TGA, SEM, XRD, XRF, BET surface area, FT-IR, Hammett indicator method, and CO2-TPD. The results found that the fresh CaO_FWC showed the specific surface area, percentage of Ca element, total basic site, and basic strength of 8.293 m2g−1, 98.6 wt.%, 8.450 mmol g−1, and 15 < H_< 18.4, respectively which similar to CaO commercial grade. In addition, the fresh CaO_FWC catalyst also presented high catalytic activity that gave %FAME of lard oil more than 96.5 %. However, the CaO_FWC catalyst could only reuse 3 times with the catalytic activity slightly decreased, and %FAME remained higher than 95 %. While the stability of the CaO_FWC catalyst was tested by storage for a long time to 180 days, this experimental data suggested that the CaO_FWC catalyst could preserve for only 30 days, with the catalytic efficiency remaining similar to the fresh CaO_FWC. Furthermore, the preservation and reusability of the catalyst were also studied in terms of the kinetic rate of reaction for use as a database to optimize the reaction conditions. Finally, the fuel properties of biodiesel products derived from lard oil and palm oil as raw materials and catalyzed by CaO_FWC catalyst met the specified standards both of EN-14214 and ASTM-D6751. Therefore, all the results of this work were excellent databases for utilizing and adding value to the Fresh-water Clamshells and lard oil as biomass sources for further development and development as renewable and alternative energy in Thailand.
HIGHLIGHTS

The CaO catalyst obtained after calcination of the Fresh-water Clamshells has displayed excellent catalytic activity for the transesterification of lard oil with biodiesel conversion and FAME yield obtained under optimal conditions up to 96.86 %
The Fresh-water Clamshells could stand promising resource for low-cost catalysts to lead the way for low-cost biodiesel
The kinetic data can be used to optimize the biodiesel production process

GRAPHICAL ABSTRACT
Study on: Multicast Routing Protocols: MOSPF and DVMRP
Authors: I. Ali Rasan , A. Shaban Awaz
Published: April 2023

Today’s networks are designed to reliably transmit traffic such as data from point to point i.e. unicasting, or from point to multipoint i.e. broadcasting. Multimedia places further demands on the network. First of all, multimedia traffic, such as audio or video, cannot tolerate delays in delivery like those tolerable by plain data transfer applications. Multimedia requires that data packets arrive on time and in the proper order at the client side. Real-time protocols and quality of service guarantees addresses this issue. Furthermore, multimedia requires transmitting large amount of traffic over the network and thus uses far more of the network’s bandwidth than in case of those basic network operations. Multicasting offers far more efficient way of transmitting such traffic over the Internet than unicasting or broadcasting ever would. The subject of this paper addresses the issue of efficient routing of such multicast traffic.

Authors:   The Korean Career·Entrepreneurship & Business Association, Kim Jongah , Choi Minchang , Nam Jungmin
Published: April 2023

In this study, empirical analysis was conducted to determine how the ESG management of the enterprise is effectively helping the enterprise and how it affects financial performance. In particular, the research was conducted through meta-analyzing with the papers already studied to determine how the areas of environmental activities, social contributions, and governance of companies affect financial performance. The subjects of the study were papers with ESG indicators and financial performance indicators among the papers published from 2011 to June 2022. The indicators of financial performance were based on ROA, and in the absence of ROA, they were analyzed using Tobin-Q, the market value relative to book value. The results of the study first identified the average effect of ESG activities on the financial performance of companies. For ESG activities as a whole, the average effect was .1302, environmental activities .1621, social activities .1551, and governance structural activities .2093. We confirmed that all have small effects size. Secondly, it was confirmed that ESG activities of companies had a positive (+) impact on the financial performance of companies, and this was statistically noted. This allows companies to confirm that ESG activities have a significant impact on their financial performance. Third, the results of the above study have been tested for publishing errors to confirm that the findings represent all studies, and we have verified that there are no errors in adjusting and publishing errors using forest lot, Egger regression analysis, and trim-and-fill techniques. This confirms that ESG activities are not a burden due to increased costs, but are useful for corporate performance, indicating that companies should be more active in ESG activities.
A Study on the Improvement of Industrial Technology Protection Capacity Considering the Generation of Technology Management of SMEs in KOREA : Focusing on the Case of Technology Leakage
Authors:   The Korean Career·Entrepreneurship & Business Association, Kim Jongho , Jung Yuhan
Published: April 2023

This study began with a research problem that the types of technology leakage may vary depending on the characteristics of generation of technology managemnet, such as management conditions and technology innovation activities of SMEs. Considering these points, it is necessary to prepare a plan to revitalize industrial technology protection in consideration of the characteristics of each generation of technology management. To this end, this study examined the characteristics of each generation of technology management, presented an analysis framework suitable for this, and then examined the cases of technology leakage from SMEs. As a result of the analysis, it was confirmed that first and second-generation technology management companies may need industrial technology protection activities, which are most important to recognize and separate major assets and establish a minimum management security system. Second, in the case of third and forth generation technology management companies, it was confirmed that additional industrial technology protection activities related to the use of strategic intellectual property rights may be necessary along with strengthening management of key personnel. These analysis results confirm the need to further consider technology innovation capabilities beyond the SME industrial technology protection policy, which has been developed around management conditions by SMEs such as size and industry.

Materials and Methods: The present case-control study was conducted from May 2016 to October 2017 on 64 patients aged ≥30 years of either sex who were diagnosed with AMI (group I) and 60 controls (group II). Patients who attended outpatient department of hospital for minor illnesses, routine health checkups, and persons accompanying patients were selected randomly as controls. The controls had no signs of AMI or coronary heart disease (CHD) on clinical examination and had normal electrocardiogram (ECG). Quantitative measurement of serum ferritin was done in all subjects. The Chi-square or Fisher’s exact test and unpaired t-test were used to compare the categorical and quantitative variables, respectively. The independent association of serum ferritin with AMI was tested using multivariate logistic regression analysis. Results: The mean serum ferritin level was significantly higher in group I (203.5 µg/L) as compared to group II (111.8 µg/L). In group I, 82.9% patients had serum ferritin ≥150 µg/L as compared to group II (15.0%) with p-value = 0.001. Multivariate analysis showed history of smoking, body mass index (BMI) >25 kg/m2 , serum ferritin levels >200 µg/L, and high-density lipoprotein (HDL) cholesterol level <35mg/dL were independent and significant determinants of AMI. Conclusions: There was an association between elevated serum ferritin levels with AMI.

Background: Pregnancy-related acute kidney injury (PRAKI) is a common problem in the developing world. Materials and methods: In this retrospective observational study at a tertiary care hospital in South India we evaluated records for the maternal, fetal, and renal outcomes in women with PRAKI. Results: Over a 10-year period, 395 patients of PRAKI were seen constituting 8.1% of all acute kidney injury (AKI). The mean age of patients was 27 ± 3 years. A total of 176 (44.5%) had pre-eclampsia, 132 (33.4%) had puerperal sepsis, 76 (19.2%) had antepartum hemorrhage or postpartum hemorrhage (APH 30/PPH 46), nine (2.2%) had hemolytic uremic syndrome (HUS). Obstruction was seen in two patients. Eleven had underlying glomerulonephritis out of three had lupus nephritis. Forty-five of 395 (11.39%) had hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome, that is, 25.5% of those with pre-eclampsia. Sixteen (4.0%) had placental abruption. A total of 288 (72.9%) presented postpartum. Renal biopsy done in 103 (26%) showed patchy cortical necrosis (PCN) in 25 (22.3%), diffuse cortical necrosis (DCN) in 23 (20.3%), acute tubular necrosis (ATN) in 20 (19.4%), acute interstitial nephritis (AIN) in 10 (9.7%), while nine (8.7%) had thrombotic microangiopathy (TMA). Glomerular disease was seen in 11. Cortical necrosis (CN) was seen in 48 patients of which 10 (20.83%) had abruption placenta, 25 (52%) had puerperal sepsis, 11 (22.9%) had postpartum hemorrhage (PPH), and two (4.1%) had TMA. A total of 290 (73.4%) required dialysis. About 76% improved while 8.3% progressed to end-stage renal disease (ESRD). Maternal mortality (MM) was 5%. There were 42 intrauterine deaths and 30 deaths in the neonatal period. Discussion: Pregnancy-related acute kidney injury in developing countries is more common as compared to the West. Only 49% patients had booked pregnancy, that is, received regular antenatal care. Apart from pre-eclampsia which is also the major cause in the West and was the etiology in 44% of patients with PRAKI in our study, sepsis (33%) and maternal hemorrhage (19%) were also significant. Immediate recovery from PRAKI was 75% however about 8% develop end-stage kidney disease (ESKD) while in the west ESKD occurred in only about 2%. Conclusion: Pregnancy-related acute kidney injury is an important cause of maternal and fetal morbidity and mortality. Pre-eclampsia emerged as the most common cause of PRAKI and CN was the most common histological lesion. Proper antenatal care and management may improve pregnancy outcomes.

Heart failure (HF) is a huge global public health task due to morbidity, mortality, disturbed quality of life, and major economic burden. It is an area of active research and newer treatment strategies are evolving. Recently angiotensin receptor-neprilysin inhibitor (ARNI), a class of drugs (the first agent in this class, Sacubitril–Valsartan), reduces cardiovascular mortality and morbidity in chronic HF patients with reduced left ventricular ejection fraction (LVEF). Positive therapeutic effects have led to a decrease in cardiovascular mortality and HF hospitalizations (HFH), with a favorable safety profile, and have been documented in several clinical studies with an unquestionable survival benefit with ARNI, Sacubitril–Valsartan. This consensus statement of the Indian group of experts in cardiology, nephrology, and diabetes provides a comprehensive review of the power and promise of ARNI in HF management and an evidence-based appraisal of the use of ARNI as an essential treatment strategy for HF patients in clinical practice. Consensus in this review favors an early utility of Sacubitril–Valsartan in patients with HF with reduced EF (HFrEF), regardless of the previous therapy being given. A lower rate of hospitalizations for HF with Sacubitril–Valsartan in HF patients with preserved EF who are phenotypically heterogeneous suggests possible benefits of ARNI in patients having 40–50% of LVEF, frequent subtle systolic dysfunction, and higher hospitalization risk

Introduction and Aim: Cardiovascular disease are a leading cause of death in the world. Atherosclerosis plays the most important role in its pathophysiology. It is a slowly progressing chronic inflammatory process resulting in increased levels of inflammatory markers in serum. hs-CRP is a novel biomarker of coronary heart disease risk prediction. Type 2 diabetes mellitus individuals are at an increased risk of developing cardiovascular diseases. In this study, we aim to find the association of HbA1c with hs-CRP in the South Indian population.
 
Materials and Methods: This was a retrospective study. The study participants were categorised into 3 groups based on their serum hs-CRP levels: Group 1 with hs-CRP < 1.0 mg/L; group 2 with hs-CRP 1.0 – 3.0 mg/L and group 3 with hs-CRP > 3.0 mg/L. The sample size was estimated to be 40 for each group. Age, fasting blood glucose, postprandial blood glucose, HbA1c, hs-CRP, total count, and ESR were collected. Statistical analyses were performed with SPSS version 16.0.
 
Results: Age showed no significant difference among the groups. FBS, PPBS, HbA1c, TLC, and ESR showed a significant difference among the 3 groups. TLC, FBS, PPBS, and HbA1c had a significant positive correlation with hs-CRP.
 
Conclusion: hs-CRP has a statistically significant positive correlation with HbA1c, fasting blood sugar, and postprandial blood sugar Additionally, we also observed that total leukocyte count had a significant positive correlation with hs-CRP and HbA1c. Hence, our results show that impaired glycemic control is associated with an increased risk of developing cardiovascular diseases.

Introduction and Aim: Parkinson's disease (PD) is a neurodegenerative disorder that destroys dopaminergic neurons in the nigrostriatal area of the midbrain this results in a movement difficulty characterised by tremors, bradykinesia, and postural instability The present in vitro study is designed to assess the beneficial (cytoprotectant and anti-inflammatory) and cyto-toxicological effects of ethanolic Withania somnifera (Ashwagandha) root extract (EWSR) in presence of Rotenone (ROT) and other known neuroprotectants (Doxycycline and Ellagic acid).
 
Materials and Methods: The nine groups used in the in vitro studies were normal control, positive control (Rotenone or Rot), W. somnifera root extract (EWSR), Doxycycline (Doxy), Ellagic acid (EA), ROT with EWSR, ROT with doxy, ROT with EA, ROT with EWSR-doxy, and ROT with EWSR-doxy-EA. The EWSR, doxy and EA treatment was started on the 24th hour following the rotenone administration and continued for the next 36 hours. After the 36th hour of protective therapy, quantification of pro-inflammatory cytokines (ELISA), cell viability or analyses of neuronal cell loss, cell cycle analysis and molecular analysis (RTPCR) was performed as a part of assessment.
 
Results: Observations from the present in vitro studies clearly demonstrate the cytoprotective and anti-inflammatory properties of EWSR, and these beneficial or protective effects got enhanced when treated in combination with Doxy and EA indicating synergistic effect in the cells that were priorly treated with ROT, and later treated with EWSR, Doxy, and EA individually and in combination.
 
Conclusion: The findings imply that EWSR reduces the in vitro effects of ROT by acting as an anti-inflammatory and cytoprotective agent.
