New rubrolides from the marine-derived fungus Aspergillus terreus OUCMDZ-1925.

Two new rubrolides, rubrolides R (1) and S (2), were isolated from the fermentation broth of the marine-derived fungus Aspergillus terreus OUCMDZ-1925. Their structures were elucidated on the basis of spectroscopic analysis and X-ray single crystal diffraction. Compound 1 showed comparable or superior antioxidation against 2,2'-azino-di(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) radicals to those of trolox and ascorbic acid with an IC₅₀ value of 1.33 mM. Compound 2 showed comparable or superior anti-influenza A (H1N1) virus activity to that of ribavirin with an IC₅₀ value of 87.1 μM. Both c

There is strong evidence obtai … tion in fish in the U.K., where estrogenic effects have been demonstrated in freshwater systems, in estuaries, and in coastal areas. In mammals, the best evidence comes from the-field studies on Baltic gray and ringed seals, and from the Dutch semifield studies on harbor seals, where both reproduction and immune functions have been impaired by PCBs in the f …

De novo sequencing and analysis of the Ulva linza transcriptome to discover putative mechanisms associated with its successful colonization of coastal ecosystems.

BACKGROUND: The green algal genus Ulva Linnaeus (Ulvaceae, Ulvales, Chlorophyta) is well known for its wide distribution in marine, freshwater, and brackish environments throughout the world. The Ulva species are also highly tolerant of variations in salinity, temperature, and irradiance and are the main cause of green tides, which can have deleterious ecological effects. However, limited genomic information is currently available in this non-model and ecologically important species. Ulva linza is a species that inhabits bedrock in the mid to low intertidal zone, and it is a major contributor

[Effects of different vegetation restoration patterns on soil bacterial community in coastal wetlands following Spartina alterniflora removal].

Vegetation restoration following Spartina alterniflora removal is critical for restoring ecological functions in coastal wetlands. However, how different restoration patterns influence soil bacterial communities remains insufficiently understood. In this study, we investigated restored wetlands in the Minjiang River Estuary, southeastern China, including salt marshes dominated by Phragmites australis and Cyperus malaccensis, and Kandelia obovata mangroves of two stand ages (6- and 16-year-old), with unrestored wetlands as control. We used high-throughput sequencing to characterize soil bacteri

Plesiomonas shigelloides Bacteremia: A Scoping Review of Epidemiology, Clinical Characteristics, Outcomes, and Implications of Antimicrobial Stewardship.

Plesiomonas shigelloides, an aquatic Gram-negative bacillus often associated with self-limiting gastroenteritis, has been reported worldwide. However, to date, no reviews have specifically investigated P. shigelloides bacteremia, which is rare and potentially fatal. This scoping review aimed to examine the existing literature to identify the epidemiology, clinical characteristics, antimicrobial susceptibility, and outcomes of P. shigelloides bacteremia. A PRISMA-ScR-guided search of PubMed, Scopus, Web of Science, and Embase identified 22 published cases, all reported as single-patient case re

[Determination of perfluorinated compounds in environmental water samples by magnetic solid-phase extraction-liquid chromatography-mass spectrometry and associated risk assessment].

Perfluorinated compounds （PFCs） are widely used， persistent， and their presence in water is of significant concern. PFCs， particularly short-chain variants， are highly soluble and mobile in water， which enables their transport over long distances via river systems， potentially leading to extensive contamination. These compounds are resistant to degradation， which is challenging for conventional water-treatment methods that often remove PFCs ineffectively， leading to their prolonged presence in water bodies. This paper establishes a magnetic solid-phase extraction method for 11 PFCs in enriched

Структурный анализ процесса сбора света с помощью антенн, содержащих родопсины в морской архееи Асгарда.

Акватические бактериальные редопсиновые протонные насосы собирают световую энергию для фотогетертрофного роста и, как известно, содержат гидроксилированные каротеи, расширяющие волны используемого света, но они не характеризуются морской археей. Здесь, комбинируя морскую хромофорную экстракт с очищенными архейскими родопсинами, выявленными в морских метагеномах, мы показываем передачу легкой энергии из различных гидроксилоидных каротеоидных в геймдаллархаэ (HeimdallRs) из некультурных морских планктонных членов «Candidatus Cariarachaeceae» (Candidatus Asgardarchaeota).

[Immunization coverage of children aged 0 to 5 years in Libreville (Gabon)].

UNLABELLED: The strategies recently implemented in Gabon have been effective in improving immunization coverage. These include, in particular, the integration of the Expanded Programme on Immunization (EPI) in primary health care centers, the integration of immunization outside of EPI, immunization by peripheral health centers according to pre-set advanced strategies, and awareness and catch-up campaigns. This descriptive, cross-sectional survey was conducted from 1 October 2007 through 30 January 2008, throughout public- and private-sector health care centers in the town of Libreville. In the

Структура и состав микробных сообществ в водной толще Южного залива Мексики и обнаружение предполагаемых микроорганизмов, деградирующих углеводороды.

В ходе этого исследования была проведена оценка сообщества бактериопланктонов и его связи с экологическими переменными, включая общую концентрацию нефтяных углеводородов (ТПГ), в районе шельфа Юкатан в Южном заливе Мексики. Анализ разнообразия бета на основе последовательности 16S rRNA показал различия в структуре общины бактериопланктона между участками отбора проб. ПЕРМАНОВА указала, что эти изменения могут быть связаны главным образом с глубокими изменениями (см.5 в адрес 180 m), концентрация растворенного кислорода (2.06 в адрес 5.93 мг L-1), и концентрация хлорофилла (0.184 в адрес 7.65 м
