动态法提取可溶性大豆多糖的纯化 及其性能分析Purification and product properties of soluble soybean polysaccharide extracted by dynamic method

open access: yesZhongguo youzhi
旨在为可溶性大豆多糖(SSPS)的纯化工艺改进和豆渣资源综合利用提供参考,采用动态法从干豆渣中提取得到SSPS粗品后,通过酶解、活性炭吸附以及醇沉等步骤进行纯化,优化了纯化工艺,并考察了纯化对SSPS的基本成分、理化指标、挥发性成分、结构和性能的影响。结果表明,最适酶解条件为木瓜蛋白酶添加量1.0%、酶解pH 6、酶解温度60 ℃、酶解时间2 h;活性炭吸附最适条件为活性炭添加量1.0%、吸附pH 5、吸附温度65 ℃、吸附时间30 min;纯化处理后SSPS的蛋白质及灰分含量分别从3.60%、5.13%

Notes on Salamandra Salamandra ssp. [PDF]

open access: yesBijdragen tot de Dierkunde, 1968
On 22-VII-1960 I caught some specimens of Salamandra salamandra fastuosa Schreiber between Lago Ercina and Lago Enol, ± 1000 m above Covadonga (Picos de Europa, Cantabrian Mountains, Spain). On 14-VIII-1961 from one of the salamanders two young were born (length 40 and 45 mm).

Robot‐Assisted Measurement of the Critical Micelle Concentration

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
The study introduces (SIMO) smart integrator for manual operations, a robotic platform for precise, repeatable determination of (CMC) critical micelle concentration in surfactants. SIMO reduces standard deviation by 80% compared to manual methods. Surfactant, dye, and diluent selection, robotic protocols, and data handling are detailed.

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Linking community structure and climate vulnerability in desert plant assemblages of southern California

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

Comparative analysis of secretomes from ectomycorrhizal fungi with an emphasis on small-secreted proteins.

open access: yesFrontiers in Microbiology, 2015
Fungi are major players in the carbon cycle in forest ecosystems due to the wide range of interactions they have with plants either through soil degradation processes by litter decayers or biotrophic interactions with pathogenic and ectomycorrhizal ...

MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

open access: yesThe Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

Active BRAF-V600E is the key player in generation of a sessile serrated polyp-specific DNA methylation profile. [PDF]

open access: yesPLoS ONE, 2018
Sessile serrated polyps (SSPs) have emerged as important precursors for a large number of sporadic colorectal cancers. They are difficult to detect during colonoscopy due to their flat shape and the excessive amounts of secreted mucin that cover the ...

Morphological and genetic relationships of Myosotis laxa ssp. baltica and ssp. caespitosa, and typification of M. laxa ssp. baltica

open access: yesActa Societatis Botanicorum Poloniae, 2011
Intraspecific taxonomy of <em>Myosotis laxa</em> has been unclear for a long time. <em>M. laxa</em> ssp. <em>baltica</em> has been treated as a microendemic taxon of the Baltic Sea region, which has evolved in the Aland Islands and has spread northwards; the spread to southeast has been declared doubtful ...

Quantitative muscle architecture in large carnivorous marsupials (Marsupialia: Dasyuridae) and links to substrate use and prey processing

open access: yesThe Anatomical Record, EarlyView.
Abstract The Dasyurid species Sarcophilus harrisii, Dasyurus maculatus, and Dasyurus viverrinus, occupying diverse ecological niches and forming a guild structure in Tasmania, provide a basis for examining the roles of various forelimb muscle groups in prey capture and locomotion.
