The novel severe acute respiratory syndrome coronavirus (SARS-COV-2) affects different people in different ways. Most infected people will develop mild to moderate respiratory flu-like illness and recover without the need for hospitalization. However, one of the not uncommonly observed extrapulmonary associations with SARS-COV-2 is developing severe large-vessel acute ischemic stroke. Moreover, COVID-19 virus-linked Cerebrovascular Accidents (CVA) were more severe and resulted in a higher risk for severe disability and mortality following acute insult. Although the pathophysiology is not fully understood, the neuro-targeting nature of SARS-COV-2 due to vascular injury and the hyperimmune response were plausible proposed mechanisms. Further research is warranted to have a deep insight into the possible mechanisms. Herein, we review the current literature and describe five patients we have encountered during the SARS-COV-2 viral pandemic.
Tracing Molecular Properties Throughout Evolution: A Chemoinformatic Approach.
Authors: Otero Marcelo , Sarno Silvina , Acebedo Sofía , Ramirez Javier Alberto
Published: January 2021

Evolution of metabolism is a longstanding yet unresolved question, and several hypotheses were proposed to address this complex process from a Darwinian point of view. Modern statistical bioinformatic approaches targeted to the comparative analysis of genomes are being used to detect signatures of natural selection at the gene and population level, as an attempt to understand the origin of primordial metabolism and its expansion. These studies, however, are still mainly centered on genes and the proteins they encode, somehow neglecting the small organic chemicals that support life processes. In this work, we selected steroids as an ancient family of metabolites widely distributed in all eukaryotes and applied unsupervised machine learning techniques to reveal the traits that natural selection has imprinted on molecular properties throughout the evolutionary process. Our results clearly show that sterols, the primal steroids that first appeared, have more conserved properties and that, from then on, more complex compounds with increasingly diverse properties have emerged, suggesting that chemical diversification parallels the expansion of biological complexity. In a wider context, these findings highlight the worth of chemoinformatic approaches to a better understanding the evolution of metabolism.
DrugPred_RNA – Structure-Based Druggability Predictions for RNA Binding Sites
Authors: Rekand Illimar Hugo , Brenk Ruth
Published: January 2021

RNA is an emerging target for drug discovery. However, like for proteins, not all RNA binding sites are equally suited to be addressed with conventional drug-like ligands. To this end, we have developed the structure-based druggability predicator DrugPred_RNA to identify druggable RNA binding sites. Due to the paucity of annotated RNA binding sites, the predictor was trained on protein pockets, albeit using only descriptors that can be calculated for both, RNA and protein binding sites. DrugPred_RNA performed well in discriminating druggable from less druggable binding sites for the protein set and delivered sensible predictions for selected RNA binding sites. In addition, the majority of drug-like ligands contained in a data set of RNA pockets were found in pockets predicted to be druggable, further adding confidence to the performance of DrugPred_RNA. The method is robust against conformational changes in the binding site and can contribute to direct drug discovery efforts for RNA targets.
BAR-based Multi-dimensional Nonequilibrium Pulling for Indirect Construction of QM/MM Free Energy Landscapes: Varying the QM Region
Authors: Sun Zhaoxi , Liu Zhirong
Published: January 2021

The indirect construction of the free energy landscape at Quantum mechanics (QM)/ molecular mechanics (MM) levels provides a feasible alternative to the direct QM/MM free energy simulations. The main idea under the indirect method is constructing a thermodynamic cycle, exploring the configurational space at a computationally efficient but less accurate low-level Hamiltonian, and performing an alchemical correction to obtain the thermodynamics at an accurate but computationally demanding high-level Hamiltonian. In our previous works, we developed a multi-dimensional nonequilibrium free energy simulation framework to obtain QM/MM free energy landscapes indirectly. Specifically, we considered obtaining semi-empirical QM (SQM) results by combining the MM results and the MM-to-SQM correction and obtaining the QM results by combining the SQM results and the SQM-to-QM correction. In this work, we explore the possibility of changing the region for electronic structure calculations in the multi-scale QM/MM treatment, which could also be considered as a change of the level of theory. More generally, the multi-dimensional nonequilibrium Hamiltonian-variation/perturbation framework could be used to obtain transformations between different Hamiltonians of interest, such as changing the QM theory, the size of the QM region, and the basis set simultaneously.
The {FeO2}8 Intermediate of the TxtE Nitration Pathway Resists Reduction, Facilitating Its Reaction with Nitric Oxide
Authors: Ding Yousong , Caranto Jonathan , Loria Rosemary , Chen Manyun , Martin Christopher , Martinez Maria
Published: January 2021

TxtE is a cytochome P450 (CYP) homolog that mediates a nitric oxide (NO)-dependent direct nitration of l-tryptophan (l-Trp) to form 4-nitrotryptophan (4-NO2-l-Trp). This nitrated product is a precursor for thaxtomin A, a virulence factor produced by plant-pathogenic bacteria that causes the disease potato scab. A recent study provided the first characterization of intermediates along the TxtE nitration pathway.1 The authors’ accumulated evidence supported a mechanism in which O2 binds to FeII TxtE to form an {FeO2}8 intermediate, which subsequently reacted with NO to ultimately form FeIII TxtE and 4-NO2-l-Trp. Typical CYP mechanisms reduce and protonate the {FeO2}8 intermediate to form a ferric-hydroperoxo species (FeIII–OOH) en route to formation of the active oxidant compound I. The previously reported lack of hydroxylated tryptophan resulting from TxtE turnover suggests that the TxtE cycle must stall at the {FeO2}8 intermediate to avoid hydroxylation. Here we present LC-MS experiments showing suggesting that TxtE can hydroxylate l-Trp by the peroxide shunt but not via reduction of the {FeO2}8 intermediate. Comparison of stopped-flow time courses in the presence and absence of excess reducing equivalents and common CYP electron transfer partners shown no spectral or kinetic evidence for reduction of the {FeO2}8 intermediate. Furthermore, the electron coupling efficiency of TB14—a self-sufficient TxtE variant with C-terminal reductase domain—to form 4-NO2-l-Trp exhibits a 3% electron coupling efficiency when it is loaded with one reducing equivalent. This efficiency increases by 2-fold when TB14 is loaded with two or four reducing equivalents. This observation provides further evidence for our key conclusion that the TxtE {FeO2}8 intermediate resists reduction. The resistance of the {FeO2}8 intermediate to reduction is a key feature of TxtE, enabling reaction with NO and efficient nitration turnover.
Role of Triplet States in the Photodynamics of Aniline
Authors: Lykhin Aleksandr , Truhlar Donald G. , Gagliardi Laura
Published: January 2021

The dynamics of excited heteroaromatic molecules is a key to understanding the photoprotective properties of many biologically relevant chromophores that dissipate their excitation energy nonreactively and thereby prevent the detrimental effects of ultraviolet radiation. Despite their structural variability, most heteroaromatic compounds share a common feature of a repulsive 1πσ* potential energy surface. This surface can lead to photoproducts, and it can also facilitate the population transfer back to the ground electronic state by means of a 1πσ*/S0 conical intersection. Here, we explore a hidden relaxation route involving the triplet electronic state of aniline, which has recently been discovered by means of time-selected photofragment translational spectroscopy [J. Chem. Phys. 2019, 151, 141101]. By using the recently available analytical gradients for multiconfiguration pair-density functional theory, it is now possible to locate the minimum energy crossing points between states of different spin and therefore compute the intersystem crossing rates with a multireference method, rather than with the less reliable single-reference methods. Using such calculations, we demonstrate that the population loss of aniline in the T1(3ππ*) state is dominated by C6H5NH2→C6H5NH⸱ + H⸱ dissociation, and we explain the long nonradiative lifetimes of the T1(3ππ*) state at the excitation wavelengths of 294‑264 nm.
Surfactant-Free Colloidal Strategies for Highly Dispersed and Active Supported IrO2 Catalysts: Synthesis and Performance Evaluation for the Oxygen Evolution Reaction
Authors: Bizzotto Francesco , Quinson Jonathan , Schröder Johanna , Zana Alessandro , Arenz Matthias
Published: January 2021

Supported Ir oxide catalysts obtained from surfactant-free colloidal Ir nanoparticles (NPs) synthesized in alkaline methanol (MeOH), ethanol (EtOH), and ethylene glycol (EG) are investigated and compared. The comparison of independent techniques such as transition electron microscopy (TEM), small angle X-ray scattering (SAXS), and electrochemistry allows shedding light on the parameters that affect the dispersion of the active phase as well as the catalytic activity. The colloidal dispersions obtained are suitable to develop supported catalysts with little NP agglomeration on a carbon support leading to highly active catalysts with more than 400 A g-1Ir reached at 1.5 VRHE for the OER. While the more common surfactant-free alkaline EG synthesis requires flocculation and re-dispersion leading to Ir loss, the main difference between methanol and ethanol as solvent is related to the dispersibility of the support material. The choice of the suitable monoalcohol determines the maximum achieved Ir loading on the support without detrimental particle agglomeration. This simple consideration on catalyst design can readily lead to significantly improved catalysts.
A Bi-Enzymatic Cascade Pathway Towards FAHFAs
Authors: Zhang Yan , Eser Bekir Engin , Guo Zheng
Published: January 2021

Recently discovered endogenous mammalian lipids fatty acid esters of hydroxy fatty acids (FAHFAs), proved to have anti-inflammatory and anti-diabetic effects. Due to their extremely low abundancies in vivo, forging a feasible scenario for FAHFA synthesis is critical for their use in uncovering biological mechanism or clinical trials. Here, we showcase a fully enzymatic approach, a novel in vitro bi-enzymatic cascade system, enabling an effective conversion of nature-abundant fatty acid into FAHFAs. Two hydratases from L. acidophilus were used for converting unsaturated fatty acids to various stereospecific hydroxy fatty acids, followed by esterification with another fatty acid catalyzed by C. antarctica lipase A (CALA). Various FAHFAs were synthesized in a preparative scale using this bi-enzymatic approach in a one-pot two-step operation mode. In all, we demonstrated that hydratase-CALA system promises a sustainable solution to the synthesis of structure-diverse stereospecific FAHFAs.

Published: January 2021

Diverse extracellular matrix patterns are observed in both normal and pathological tissue. However, most current tools for quantitative analysis focus on a single aspect of matrix patterning. Thus, an automated pipeline that simultaneously quantifies a broad range of metrics and enables a comprehensive description of varied matrix patterns is needed. To this end, we have developed an ImageJ plugin called TWOMBLI, which stands for The Workflow Of Matrix BioLogy Informatics. This pipeline includes metrics of matrix alignment, length, branching, end points, gaps, fractal dimension, curvature, and the distribution of fibre thickness. TWOMBLI is designed to be quick, versatile and easy-to-use particularly for non-computational scientists. TWOMBLI can be downloaded from https://github.com/wershofe/TWOMBLI together with detailed documentation and tutorial video. Although developed with the extracellular matrix in mind, TWOMBLI is versatile and can be applied to vascular and cytoskeletal networks. Here we present an overview of the pipeline together with examples from a wide range of contexts where matrix patterns are generated.

Published: January 2021

Entendemos que o cinema, enquanto ferramenta educativa, contribui para interpelar a história e a memória dos povos africanos e afrodescendentes na formação do povo brasileiro instituída na lei 10.639/2003 como temática obrigatória no Ensino Regular. Deste modo, objetivamos, a partir de uma análise fílmica, reflexionar a construção da personagem Chica da Silva no filme “Xica da Silva” (1976), de Carlos Diegues, considerando a representação do corpo negro. Nosso ponto de partida é a crítica dirigida ao filme (publicada no jornal semanário “Opinião” em 1976, declarado de cunho alternativo e de esquerda) pela historiadora Maria Beatriz Nascimento e a resposta do supracitado diretor, em entrevista concedida a Pola Vartuck, Estado de S. Paulo em 1978. Conclui-se que o filme aponta para uma contenda que indica um contexto de conflitos entre a perspectiva da esquerda na construção do movimento negro organizado e a produção do cinema novo nacional e suas alternativas, apontando fatores que traduzem a expressão do corpo negro feminino no referido filme.

Published: January 2021

Artikel ini tentang pentingnya motivasi belajar yang berfungsi sebagai usaha dalam pencapaian prestasi. Dalam belajar-mengajar, motivasi merupakan faktor yang sangat penting, karena dengan adanya motivasi dapat menumbuhkan minat belajar peserta didik. Bagi peserta didik yang memiliki motivasi yang kuat akan mempunyai energi untuk melaksanakan kegiatan belajar. Kurangnya motivasi belajar pada pelajaran Akidah Akhlak di MI Malihatul Hikam Lamongan kelas VI mengakibatkan hasil belajarnya yang kurang dari KKM, yaitu mendapat nilai minimal 70,00. Sedangkan dilihat dari hasil belajar siswa kelas I di MI Malihatul Hikam Lamongan bahwa nilai rata-rata siswa 60,00. Jadi hasil belajar siswa kurang berhasil karena antara KKM dan rata-rata lebih rendah rata-ratanya karena masih menggunakan strategi yang konvensional. Oleh sebab itu, diperlukan metode pembelajaran yang membuat siswa belajar dengan semangat dan lebih bermakna, yakni metode pembelajaran Teams Games Tournament (TGT). Tujuan penelitian ini adalah untuk mengetahui efektivitas penerapan metode Teams Games Tournament untuk meningkatkan motivasi belajar siswa. Penulis menerapkan penelitian tindakan kelas (classroom action research) dengan model dari Kemmis dan Mc Taggart, yang perangkatnya terdiri atas empat komponen, yaitu planning (perencanaan), acting (tindakan), observing (pengamatan), dan reflecting (refleksi). Penelitian ini menunjukkan bahwa penerapan metode Teams Games Tournament bisa meningkatkan motivasi belajar siswa.
Hans Jonas e o profético na filosofia: sobre os 40 anos de Das Prinzip Verantwortung
Authors: Lopes Wendell Evangelista Soares
Published: January 2021

O presente ensaio apresenta uma análise crítica do problema do profético na filosofia a partir de uma consideração da reflexão moral de Hans Jonas em Das Prinzip Verantwortung (1979). Jonas demonstra ter seguido, bem de perto, deliberadamente ou casualmente uma sabedoria prática específica de Kant, a saber: a necessidade de fazer da filosofia um instrumento profético. O ensaio realiza, portanto, uma espécie de avaliação retrospectiva da fortuna do livro tendo em vista os seus resultados esperados, o que possibilitará de maneira secundária também uma nova aproximação da ética da responsabilidade com a filosofia da história e a reflexão moral de Kant, bem como permitirá uma avaliar também do quanto o profético vale para o filosofia.

Authors: Abdur Rashid  , Ilyas Sharif  , Shakeel Khan  , Fazal Malik
Published: January 2021

Effective time management leads to greater academic performance and reduces stress, strain and anxiety among students, however, students facing difficulties to keep a balance between their academic life and personal-social life. This study aims to examine the self-perceptions of undergraduate students’ time management behaviour by using Time Management Behaviour Scale (TMBS) developed by Macan, Shahani, Dipboye and Phillips (1990). The scale consisted of 34 rating items ranges from very often true to seldom true. The population of the study consisted of all undergraduate students studying in the academic session 2018-19 at public sector general category universities in Malakand division. By using stratified sampling technique a sample of 1050 undergraduate students were selected from the sampled universities. Students were also asked to provide their CGPA in their previous semester. Both descriptive and inferential statistics were used to analyze the data. It was found that prospective teachers have moderate to high level of time management skills. Significant relationship was found between undergraduate students’ time management behaviour and academic performance. It was recommended that university administration should orient students to enhance their time management behaviour by arranging seminars, workshops and conferences to enhance their time management skills.
Socio-Economic and Political Impacts of Vocational Trainings on Tribal Community of Pakistan
Authors: Sami Ullah  , Zilakat Khan Malik
Published: January 2021

This study was conducted to evaluate the role of vocational training imparted by the Federally Administered Tribal Area’s Development Authority (FATA-DA) in the socio-economic and political development of the tribal community in Pakistan. The survey was initiated in the year 2018 in FATA where 400 males in the age group (16-35 years) were selected for data collection through a disproportionate simple random sampling procedure. Cross Tabulation Analysis was conducted using SPSS. The result indicates that vocational training imparted by FATA-DA contributed very less to the socio-economic and political development of FATA’s youth. Among 13 indicators, the impact on only 02 indicators was found significant for the treatment group. This study concluded that vocational training does have a contribution to the socio-economic development of youth but in the case of FATA-DA sponsored training, the result was not desirable. This might be due to certain quality issues that must be taken into consideration during initiating a vocational training program for the socio-economic and political development of youth.

Negationsforschung im Paradigmenwechsel um die Jahrtausendwende
Authors: Paslawska Alla
Published: January 2021

Als 1989 die Germanistik an der Universität Gdansk gegründet wurde, stand das sowjetische Imperium direkt vor seinem Niedergang. Der Zerfall der Sowjetunion zeichnete sich unter anderem durch eine rasche Entwicklung nationaler Wissenschaften im postsowjetischen Raum, die sich in das gesamteuropäische Bildungssystem integrieren wollten. Dieser Prozess wurde auch durch einen Paradigmenwechsel in nationalen Linguistiken im Ganzen und in deren Germanistiken im Einzelnen begleitet. Das Ziel des Beitrags ist, am Beispiel einer universalen linguistischen Kategorie der Negation zu zeigen, welche wichtigen Schritte die Germanistik in den letzten 30 Jahren zurückgelegt hat. Die Untersuchung konzentriert sich auf die Inlandsgermanistik und zwei Auslandsgermanistiken – die polnische und die ukrainische.
The vasculature of the stomach and intestinal tract during compression stenosis of the celiac axis
Authors:   Azerbaijan Medical University. Department of Human Anatomy and Medical Terminology. Baku. Azerbaijan
Published: January 2021

At the current moment, there is no single approach regarding diagnostics and after-treatment of compression stenosis of the celiac axis. This work aims to study the state of the vasculature of the stomach and intestinal tract during compression stenosis of the celiac axis. Compression stenosis of the celiac axis is a disease caused by extravasal pressure of the celiac axis of the abdominal aorta applied by the arcuate ligament of the diaphragm, diaphragmatic peduncle, or neurophibromatic tissue of celiac plexus. It presents in chronic abdominal pain, dyspeptic events, and neurovegetative disorders. This work aims to study the state of the vasculature of the stomach and intestinal tract during compression stenosis of the celiac axis. Materials and methods. Intraorgan vasculature has been studied – 18 specimens of stomachs and intestinal tracts, gathered during autopsies of dead bodies with compression stenosis of the celiac axis. Autopsie material has been studied sensu L. Reiner. Research has been conducted with angiology, roentgenologic and histologic methods. To achieve the set goal a universal method has been developed, based on classical impregnation methods: intravascular – Ranvier-Goyer, and immersional – Belschowsky-Gros. Results. The conducted research has allowed locating significant changes of histostructure of microcirculation vessels’ vascular wall: wall shredding, edema of basal membrane, swelling of perivascular connective tissue. Overall the stomach and intestinal tract looked paralytically dilated. The most prominent morphologic changes of microvasculature have been revealed in the pyloric part of the stomach and first intestinal segment of dodecadactylon. In addition to diffuse atrophic changes of the stomach lining and intestinal lining, observed during stenosis of the celiac axis, these changes take the form of helcoid process in separate parts of it. As a result, the conducted research has allowed exposing prominent changes of histostructure of vascular walls of stomach and intestines during compression stenosis of the celiac axis.
Cotas raciais nas Universidades Públicas Federais: identidade, auto referência e reconhecimento
Authors: Montenegro de Lima Clóvis Ricardo , Andrade Maribel da Rosa , Lopes Wilke Valeria Cristina
Published: January 2021

Neste artigo investiga-se e se discute as cotas raciais nos processos de seleção e ingresso nas Universidades públicas federais. Esta política tem menos de 10 anos de implementação no Brasil e, apesar de bons resultados obtidos, segue sendo tema de controvérsias. Quer-se discutir esta política a partir do conceito de reconhecimento em Habermas e Honneth. O reconhecimento parte de uma noção distinta da idealização identitária, sendo ele uma construção intersubjetiva. A discussão que denominamos culturalista das cotas raciais parte da noção de identidade como substância e distinção. Quer-se fazer uma crítica dessa perspectiva teórica e prática. Em seguida será apresentado uma questão inusitada na política de cotas raciais nas universidades: a autoreferência da identidade racial nos processos abriu as portas para fraudes, e muitas delas foram identificadas e punidas. Este fato demanda a discussão de quem são os indivíduos que cabem nas cotas raciais. A autoreferência torna-se insuficiente para definir raça e, o reconhecimento pelo outro é ele mesmo uma validação numa dinâmica intersubjetiva.
Chronic Suppurative Otitis Media Contributory Factors and their Prevention
Authors: Akhtar Naeem , Haneef Muhammad , Naeem Asma
Published: January 2021

Background: Chronic suppurative otitis media has declined in the developed countries because of better health resources and better socioeconomic status of the people, but it still remains a major health problem in developing countries like Pakistan. Chronic suppurative otitis media (CSOM) is relatively common among illiterate people having poor socioeconomic status residing in the rural areas. Objective: To identify the contributory factors responsible for chronic suppurative otitis media and to devise strategies to prevent them. Study Design: Cross sectional observational study. Settings: This study was conducted in the department of ENT and Head & Neck surgery allied hospital (FMU) Faisalabad Pakistan. Duration: Two years from September 2016 to August 2018. Methodology: A total of 150 patients with CSOM, both tubotympanic and atticoantral types, were included. The patients of either gender with CSOM, both tubotympanic and atticoantral types, ranging from 03 to 64 years and giving consent for any surgical intervention if required were included in the study. Patients below 03years and above 64 years, having acute suppurative otitis media with complication, and patients not willing for any surgical intervention were excluded from the study. Results: Out of 150 patients of the study 60% patients were males and 40% were females with male : female ratio of 1.5 : 1. The age range was found to be 3-64 years with mean age of 28.9 years. Socioeconomic status showed that 62.8% patients with CSOM belonged to poor class (tubotympanic-46.8% & atticoantral -16%), 23.9% patients had middle class (tubotympanic-16.6% & atticoantral-7.3%) and 13.3% patients belonged to upper class (tubotympanic - 11.3% & atticoantral – 2%). 84 patients (56%) were under matric (tubotympanic-42% & atticoantral – 14%). 57.2% patients were rural residents and 42.8% patients were urban residents in case of tubotypmpanic type of CSOM while 55.2% patients were rural and 44.8% patients were urban in case of atticoantral type of CSOM. SPSS software version 10 was used to analyse the data. Chi square test was applied for analysis. Tubotympanic type of CSOM cases were treated conservatively along with surgical treatment where indicated. All cases of atticoantral type of CSOM were treated by surgery. Conclusion: CSOM is still an important public health problem in developing countries like Pakistan due to poverty, illiteracy, malnutrition, lack of health education and people living in substandard & rural areas. It is the need of the hour that health education programs should be organized to raise the awareness about the disease among the people.

This survey research aims to analyze the factors that influence, as well as test differences in the subjective well-being of the families of women health workers during the Covid-19 pandemic, according to the two types of working time (Stable and shift). This study involved 110 families (47 stable and 63 shift working hours) from Jabodetabek area, which was selected by non-probability random sampling. Data were collected in April 2020. The results showed that women health workers with stable working hours had significantly higher subjective well-being, financial management, and marriage satisfaction, but otherwise had lower husband-wife interactions and work and family problems than women with shift working hours. The results of the main regression model showed that family well-being was influenced positively by coping strategies, marital satisfaction, and husband's education. Meanwhile, the derivative regression model that analyzes the variable components showed that family well-being was influenced positively by a component of marriage satisfaction, a component of family interaction, implementation of family time management, and husband's education; but negatively influenced by family income and husband's age. In general, the family of women health workers during the Covid-19 pandemic was expected to develop various efforts to increase marriage satisfaction and the family's subjective well-being.

The sunfish or mola fish (Mola spp.) is one of marine tourismÃ¢â¬â¢ icon in Nusa Penida waters where they appear seasonally. This study was aimed to observe the habitat characteristics of mola fish at the depths of diving tourism where they are visible. The research was conducted from July to December 2019 using survey and descriptive methods to obtain information of mola fish animal linked to habitat conditions. On its appearance data on depths, temperatures, currents, and the presence of symbiotic fishes were observed directly assisted by dive center operators. By comparing the morphological characteristics shown photographically, it is assumed that mola fish in study area is composed by two species, M. alexandrini and M. mola. The highest individual record was in September and decreasing along the incoming months. Mola fish prefers calm deeper water with lower temperatures coincides with the presence of cleaning reef fishes.ÃÂ

Coral reefs are unique ecosystems and only occur in the tropics area. One of the coral reef distribution in Indonesia is Lombok Island. The coral reefs in Lombok Island under degradation conditions caused by natural and human activities. The purpose of this study was to provide an overview of the benthic profile and substrate of coral reefs in the Labuhan Pandan waters, Eastern Lombok. Observations were conducted in March 2019 at 5 stations using the Underwater Photo Transect (UPT) method. The results showed that in general benthic coral reefs were dominated by Acropora Branching (35.40%) then followed by Soft Coral (20.89%), DCA (14.08%), Coral Foliose (11.07%), Rubble (7.36%) and Halimeda (2.77%). The highest percentage of Acropora Branching were found at KND_01 station (63.33%) followed by PTG_01 (49.13%), PTG_02 (31.18%), BDR_01 (21.73%), and PTG_03 (11.00%). The highest DCA percentage was found at BDR_01 station (29.27%) while Soft Coral was found dominant at PTG_02 (47.67%). Halimeda was only found in PTG_02 (1.87%) and PTG_03 (12.00%). Differences in the composition of benthic and substrate may be caused by differences in water conditions at each station.

A field survey was carried out to increase knowledge on salts produced from plants in the west of Ivory Coast. This work intends to serve as a basis for a real promotion of "plant salts" as a food additive in domestic and industrial production. It would also like to provide an alternative to severe low-sodium diets. It is produced in the west of Ivory Coast, salty products made from plants and used as a substitute of sodium chloride. These "edible plant salts" are differentiated from each other by the type of plant (and even organ) used and the manufacturing process. Two manufacturing processes, resulting in physically different salts, were identified. The first, used by the non-native Malinke, gives the lumpy "potash" commonly sold at the markets. The second, practiced by the native Dan, Guere an Wobe peoples, gives a better developed fine "plant salts". The main “edible plant salts” found in this area are produced from palm or coconut branches. The salts from reeds and many forest trees such as kapok trees are also very appreciated, only they are rare. "Plant salts" are in greater demand for health reasons, hence their qualification as "salts of the sick people". They are consumed as a cooking ingredient or in pharmacopoeia and the elderly are their first consumers. Due to weak demand, productions are very irregular and in low quantities. These products are unknown to populations and industrialists although they could be useful in food and health sectors.
