This review outlines the research that was carried out regarding the isolation of bioactive compounds from marine-derived bacteria and fungi by China-based research groups from 2009–2018, with 897 publications being surveyed. Endophytic organisms featured heavily, with endophytes from mangroves, marine invertebrates, and marine algae making up more than 60% of the microbial strains investigated. There was also a strong focus on fungi as a source of active compounds, with 80% of publications focusing on this area. The rapid increase in the number of publications in the field is perhaps most notable, which have increased more than sevenfold over the past decade, and suggests that China-based researchers will play a major role in marine microbial natural products drug discovery in years to come.

Degrading Microorganism

Background: Over the past years, the continuous use of herbicides has raised increasing concern mainly due to their massive pollution of the environment. To address this problem, the herbicide-degrading microorganism might be very promising. Method: In the present study, a total of twenty (20) soil samples were collected, bacteria and fungi were isolated from the soil and identified using standard microbiological and molecular studies. Results: The results revealed that a total of 2 bacterial (Enterobacter asburiae and Pseudomonas aeruginosa) and 2 fungi (Aspergillus flavus and Fusarium redolens) strains were isolated from the soil samples collected from herbicide contaminated soil in Keffi, Nasarawa State, Nigeria. The E. asburiae and P. aeruginosa had 75.0%, and 100% occurrence while the fungi isolates including the A. flavus and F. redolens had 75.0%, and 100% occurrence respectively. The 16S rDNA and ITS1F analysis confirmed the identity of the bacteria and fungi genus. Phylogenetic analysis suggested the bacteria strains were closely related to Pseudomonas aeruginosa strain CIFRI DTSB1 and Enterobacter sp revealed a close relatedness with Enterobacter asburiae RD-DAROS-04 strain, whereas, the fungi strain revealed a closely relatedness of Fusarium redolens strainTIST190421511. Conclusion: In conclusion, the microbial strains including Pseudomonas aeruginosa strain CIFRI DTSB1, Entrobacter asburiae RD-DAROS-04, and Fusarium redolens strainTIST190421511 were the major microbial habitant of pesticide-contaminated farmland in Keffi, and thus represent the herbicide degrading microorganism in this region. Further studies on the herbicide degrading properties of these microbial strains are underway.

Summary: In the past suicidal behavior among Black South Africans has been largely underresearched. Earlier studies among the other main ethnic groups in the country showed suicidal behavior in those groups to be a serious problem. This article briefly reviews some of the more recent research on suicidal behavior in Black South Africans. The results indicate an apparent increase in suicidal behavior in this group. Several explanations are offered for the change in suicidal behavior in the reported clinical populations. This includes past difficulties for all South Africans to access health care facilities in the Apartheid (legal racial separation) era, and present difficulties of post-Apartheid transformation the South African society is undergoing, as the people struggle to come to terms with the deleterious effects of the former South African racial policies, related socio-cultural, socio-economic, and other pressures.

A Current

Ever since the 1968 student movements and the events surrounding the Tlatelolco massacre, Mexico City rock bands have openly engaged with the intersection of music and memory. Their songs offer audiences a medium through which to come to terms with the events of the past as a means of praising a broken world, to borrow the poet Adam Zagajewski’s phrase. Contemporary songs such as Saúl Hernández’s “Fuerte” are a twenty-first-century voicing of the ceaseless revolutionary spirit that John Gibler has called “Mexico unconquered,” a current of rebellion and social hunger for justice that runs in the veins of Mexican history. They are the latest additions to what we might think about as “the Mexico unconquered songbook”: musical critiques of impunity and state violence that are rooted in the weaponry of memory, refusing to focus solely on the present and instead making connections with the political past. What Octavio Paz described as a “swash of blood” that swept across “the international subculture of the young” during the events in Tlatelolco Plaza on October 2, 1968, now becomes a refrain of musical memory and political consciousness that extends across eras and generations. That famous phrase of Paz’s is a reminder that these most recent Mexican musical interventions, these most recent formations of a Mexican subculture of the young, maintain a historically tested relationship to blood, death, loss, and violence.

The Way

This book is concerned with the way in which forces of change, from the fields of finance and non-financial corporates, cause participants in the corporate reorganization process to adapt the ways in which they mobilize corporate reorganization law. It argues that scholars, practitioners, judges, and the legislature must all take care to connect their conceptual frameworks to the specific adaptations which emerge from this process of change. It further argues that this need to connect theoretical and policy concepts with practical adaptations has posed particular challenges when US corporate reorganization law has been under examination in the decade since the financial crisis. At the same time, the book suggests that English scholars, practitioners, judges, and the legislature have been more successful, over the course of the past ten years, in choosing concepts to frame their analysis which are sensitive to the ways in which corporate reorganization law is currently used. Nonetheless, it suggests that new problems may be on the horizon for English corporate reorganization lawyers in adapting their conceptual framework in the decades to come.

Complex Sphingolipids

Sphingolipids are complex lipids widespread in nature as structural components of biomembranes. Commonly, the sphingolipids of marine organisms differ from those of terrestrial animals and plants. The gangliosides are the most complex sphingolipids characteristic of vertebrates that have been found in only the Echinodermata (echinoderms) phylum of invertebrates. Sphingolipids of the representatives of the Asteroidea and Holothuroidea classes are the most studied among all echinoderms. In this review, we have summarized the data on sphingolipids of these two classes of marine invertebrates over the past two decades. Recently established structures, properties, and peculiarities of biogenesis of ceramides, cerebrosides, and gangliosides from starfishes and holothurians are discussed. The purpose of this review is to provide the most complete information on the chemical structures, structural features, and biological activities of sphingolipids of the Asteroidea and Holothuroidea classes.

Here I build upon Robert Orsi’s work by arguing that we can see presence—and the longing for it—at work beyond the obvious spaces of religious practice. Presence, I propose, is alive and well in mediated apocalypticism, in the intense imagination of the future that preoccupies those who consume its narratives in film, games, and role plays. Presence is a way of bringing worlds beyond into tangible form, of touching them and letting them touch you. It is, in this sense, that Michael Hoelzl and Graham Ward observe the “re-emergence” of religion with a “new visibility” that is much more than “simple re-emergence of something that has been in decline in the past but is now manifesting itself once more.” I propose that the “new awareness of religion” they posit includes the mediated worlds that enchant and empower us via deeply immersive fandoms. Whereas religious institutions today may be suspicious of presence, it lives on in the thick of media fandoms and their material manifestations, especially those forms that make ultimate promises about the world to come.

Over the past thirty years, a number of researchers have investigated on 3D organ reconstruction from medical images and there are a few 3D reconstruction software available on the market. However, not many researcheshave focused on3D reconstruction of breast cancer’s tumours. Due to the method complexity, most 3D breast cancer’s tumours reconstruction were done based on MRI slices dataeven though mammogram is the current clinical practice for breast cancer screening. Therefore, this research will investigate the process of creating a method that will be able to reconstruct 3D breast cancer’s tumours from mammograms effectively.  Several steps were proposed for this research which includes data acquisition, volume reconstruction, andvolume rendering. The expected output from this research is the 3D breast cancer’s tumours model that is generated from correctly registered mammograms. The main purpose of this research is to come up with a 3D reconstruction method that can produce good breast cancer model from mammograms while using minimal computational cost.

Time, according to medieval theologians and philosophers, was experienced in radically different ways by God and by his creation. Indeed, the obligation to dwell in time, and therefore to have no sure knowledge of what was to come, was seen as one of the primary qualities which marked the post-lapsarian state. When Adam and Eve were cast out of the garden of delights, they entered a world afflicted with the changing of the seasons, in which they were obliged to work and consume themselves with the needs of the present day and the still unknown dangers of the next. Medieval concerns about the use and abuse of time were not merely confined to anxiety about the present, or awareness of seized or missed opportunities in the past. The future was equally worrying, in particular the extent to which this part of time was set aside for God alone, or whether it was permissible to seek to know the future, either through revelation and prophecy, or through science. In the fourteenth and fifteenth centuries, the scientific claims of astrology to provide a means to explain the outcome of past and future events, circumventing God’s distant authority, became more and more insistent. This paper begins by examining one skirmish in this larger battle over the control of the future.

Marine invertebrates have been reported to be an excellent resource of many novel bioactive compounds. Studies reported that Indonesia has remarkable yet underexplored marine natural products, with a high chemical diversity and a broad spectrum of biological activities. This review discusses recent updates on the exploration of marine natural products from Indonesian marine invertebrates (i.e., sponges, tunicates, and soft corals) throughout 2007–2020. This paper summarizes the structural diversity and biological function of the bioactive compounds isolated from Indonesian marine invertebrates as antimicrobial, antifungal, anticancer, and antiviral, while also presenting the opportunity for further investigation of novel compounds derived from Indonesian marine invertebrates.
