Getting back to the grass roots: harnessing specialized metabolites for improved crop stress resilience.

Curr Opin Biotechnol 2021 08 12;70:174-186. Epub 2021 Jun 12.

Section of Cell and Developmental Biology, University of California at San Diego, La Jolla, CA, USA. Electronic address:

Roots remain an understudied site of complex and important biological interactions mediating plant productivity. In grain and bioenergy crops, grass root specialized metabolites (GRSM) are central to key interactions, yet our basic knowledge of the chemical language remains fragmentary. Continued improvements in plant genome assembly and metabolomics are enabling large-scale advances in the discovery of specialized metabolic pathways as a means of regulating root-biotic interactions.

Factors controlling accumulation of organic carbon in a rift-lake, Oligocene Vietnam.

Sci Rep 2020 09 11;10(1):14976. Epub 2020 Sep 11.

Geological Survey of Denmark and Greenland, Øster Voldgade 10, 1350, Copenhagen, Denmark.

Understanding of the processes of petroleum source rock (SR) accumulation in lacustrine rift basins and the behavior of lake systems as long-term carbon sinks is fragmentary. Investigation of an 800 m thick (500 m core and ~ 300 m outcrop), deep-lacustrine, Oligocene section in Vietnam, provides a rare insight into the controls and deposition of organic carbon (OC) and SR formation in continental rift basins. A multidisciplinary dataset, combining elemental data, inorganic and organic geochemistry with sedimentology, shows that the richest alginite-prone, sapropelic SR developed during periods of relative tectonic quiescence characterized by moderate primary productivity in a mainly dysoxic lacustrine basin.

[Intraoperative vascular fluorescence in cerebral glioblastomas and vascular histological features].

Zh Vopr Neirokhir Im N N Burdenko 2019 ;83(6):21-34

Serbsky National Medical Research Center for Psychiatry and Narcology, Moscow, Russia.

5-ALA intraoperative fluorescence is widely used in surgery of brain tumors for intraoperative demarcation of boundaries and more total resection because 5-ALA metabolites are not accumulated in the intact brain and vascular tissues. Given this fact, it was hypothesized that fluorescence of vessels in the immediate vicinity of a brain tumor may indicate their infiltration by tumor cells as a potential pathway for their dissemination and as a factor for continued tumor growth after surgery and adjuvant therapy.

Purpose: Identification of fluorescent vessels located near cerebral gliomas, with a histological description of their structure, relationships with the tumor, and potential invasion of the walls by tumor cells. Read More

Public versus internal conceptions of addiction: An analysis of internal Philip Morris documents.

PLoS Med 2018 05 1;15(5):e1002562. Epub 2018 May 1.

Center for Tobacco Control Research and Education, University of California, San Francisco, San Francisco, California, United States of America.

Background: Tobacco addiction is a complex, multicomponent phenomenon stemming from nicotine's pharmacology and the user's biology, psychology, sociology, and environment. After decades of public denial, the tobacco industry now agrees with public health authorities that nicotine is addictive. In 2000, Philip Morris became the first major tobacco company to admit nicotine's addictiveness. Read More

Securitarian healing: Roma mobility and health care in Rome.

Authors:
Lorenzo Alunni

Med Anthropol 2015 30;34(2):139-49. Epub 2014 Oct 30.

a IRIS - École des Hautes Études en Sciences Sociales , Paris.

Over the last decade, Roma populations in Europe have been the object of strict securitarian policies. The Rome case is particularly interesting due to the continued shift from securitarian to humanitarian discourses and actions led by local institutions. The specific health care system implemented in the legal and illegal Roma camps was one of the tools used. Read More

Cyclic loading of fractured cadaveric femurs after elastomer femoroplasty: an in vitro biomechanical study.

Clin Biomech (Bristol, Avon) 2012 Oct 7;27(8):819-23. Epub 2012 Jun 7.

Leiden University Medical Center, Department of Surgery, Leiden, The Netherlands.

Background: Elastomer femoroplasty is a novel and experimental approach in the prevention of hip fracture surgery. Previously, we published the results of an in vitro cadaveric experiment in which we showed a significant reduction of fracture displacement in treated femurs. The aim of the present study was to establish the failure loads and inter-fragmentary movement of fractured, elastomer femoroplasty treated femurs during cyclic loading. Read More

Lack of metabolic ageing in the long-lived flatworm Schmidtea polychroa.

Exp Gerontol 2011 Sep 23;46(9):755-61. Epub 2011 Apr 23.

Laboratory for Ageing Physiology and Molecular Evolution, Biology Department, Ghent University, K.L. Ledeganckstraat 35, 9000 Ghent, Belgium.

Freshwater planarians have a large totipotent stem cell population allowing high rates of cell renewal and morphological plasticity. It is often suggested that they are able to rejuvenate during fission, regeneration and starvation. These features, together with the rapidly expanding molecular toolset, make planarians such as Schmidtea polychroa and S. Read More

SIMAC: development and implementation of a coral reef monitoring network in Colombia.

Rev Biol Trop 2010 May;58 Suppl 1:67-80

Instituto de Investigaciones Marinas y Costeras, INVEMAR, Punta de Betín, Zona Portuaria, Santa Marta, Colombia.

Significant coral reef decline has been observed in Colombia during the last three decades. However, due to the lack of monitoring activities, most of the information about health and changes was fragmentary or inadequate. To develop an expanded nation-wide reef-monitoring program, in 1998 INVEMAR (Instituto de Investigaciones Marinas y Costeras: "Colombian Institute of Marine and Coastal Research") designed and implemented SIMAC (Sistema Nacional de Monitorco de Arrecifes Coralinos en Colombia: "National Monitoring System of Coral Reefs in Colombia") with the participation of other institutions.

An SOS response induced by high pressure in Escherichia coli.

J Bacteriol 2004 Sep;186(18):6133-41

Laboratory of Food Microbiology, K.U.Leuven, Kasteelpark Arenberg 22, B-3001 Heverlee, Belgium.

Although pressure is an important environmental parameter in microbial niches such as the deep sea and is furthermore used in food preservation to inactivate microorganisms, the fundamental understanding of its effects on bacteria remains fragmentary. Our group recently initiated differential fluorescence induction screening to search for pressure-induced Escherichia coli promoters and has already reported induction of the heat shock regulon. Here the screening was continued, and we report for the first time that pressure induces a bona fide SOS response in E. Read More

[Man and his fellow-creatures under ethical aspects]

ALTEX 1998 ;15(4):163

D-Bayreuth.

Since in 1995, ALTEX offered the literary report a kind of journalistic home and - being a scientific journal - opened up even more in the direction of the Arts, the ethical dialogue could gain in shape as well as in colour. To deepen this co-operation even further every fourth issue of the quarterly has "ethics" as its emphasis. This provides the chance to give access in one issue to topical texts which were mentioned in the report but could not be cited in full length. Read More

United States-Japan workshop on New Rodent Models for the Analysis and Prevention of Carcinogenesis.

Cancer Epidemiol Biomarkers Prev 1999 Nov;8(11):1033-7

Department of Environmental Health Sciences, Johns Hopkins School of Public Health, Baltimore, Maryland 21205-2179, USA.

In assessing the present status of rodent models for the analysis and prevention of carcinogenesis, the discussion emphasized that models exist for very few of the major cancers occurring in the United States and Japan. Almost without exception, those that do exist were invented for etiological and mechanistic studies of chemical and physical carcinogenesis. Applicability to cancer chemoprevention was not a primary objective in their development. Read More

Sperm chemotaxis: egg peptides control cytosolic calcium to regulate flagellar responses.

Dev Biol 1994 Sep;165(1):10-9

Department of Biochemistry, University of Washington, Seattle 98195.

Fragmentary evidence indicates that intracellular [Ca2+] (Cai) mediates sperm chemotaxis. However, neither correlations of swimming responses to chemoattractant-induced alterations of Cai nor explanations of how chemoattractant gradients control Cai exist. Here Cai increases produced by the egg peptide speract-not previously known to cause flagellar responses--were prolonged by treatment with 3-isobutyl-1-methylxanthine (IBMX). Read More

Resistance of bacteria to antibacterial agents: report of Task Force 2.

Authors:
T F O'Brien

Rev Infect Dis 1987 May-Jun;9 Suppl 3:S244-60

The use of a growing number of antibacterial agents over the past half century has elicited a widespread deployment of genes for resistance to these agents in populations of bacteria throughout the world. Task Force 2 of the NIH Study on Antibiotic Use and Antibiotic Resistance Worldwide found that data on prevalence of resistance was fragmentary and underanalyzed but indicative of several trends. Resistance to older antibacterial agents appears to have stabilized overall, but shifts of resistance genes into new strains and species have continued to cause new clinical problems. Read More

Vitamin requirements of intravenously fed man.

J Environ Pathol Toxicol Oncol 1985 Jul;5(6):91-102

The continued refinements in the application of intravenous feeding must include the provision of optimal micronutrients if the clinical utility of this technique is to be fully realized. From the above discussion, it is readily apparent that our understanding of vitamin requirements during IVF is fragmentary at best. This limited knowledge has unfortunately been extrapolated to the daily regimen of nearly all parenterally nourished patients. Read More

Diagnosis and management of eustachian tube malfunction.

Authors:
B Magnuson B Falk

Otolaryngol Clin North Am 1984 Nov;17(4):659-71

The eustachian tube is an essential part of the pressure regulating system of the middle ear. The physiologic function of the tube is to equalize the middle ear pressure with that of the atmosphere, and at the same time make the middle ear independent of the nasopharyngeal environment with its loud sounds, extensive respiratory pressure changes, and potentially harmful bacterial flora. Thus, the protective closing action is essential in the normal physiology of the eustachian tube, and lack of protection is central in tubal malfunction. Read More
