BLOC: Buildable and Linkable Organ on a Chip

open access: yesAdvanced Materials Technologies, EarlyView.
We developed a “Buildable and Linkable Organ on a Chip” (BLOC) that can construct diverse microphysiological systems (MPSs). The BLOC is standardized to the same size and has one of the functions of “Culture,” “Control,” or “Analysis.” Users can freely configure various MPSs, including developing perfusion, cytotoxicity analysis, and biochemical ...

Two‐Photon Polymerized Microvascular Environments for Multicellular Modeling of the Blood–Brain Tumor Barrier

open access: yesAdvanced Materials Technologies, EarlyView.
Modeling the blood–brain tumor barrier is challenging due to complex interactions between brain microvasculature and glioma cells. We present two‐photon polymerized 3D micro‐porous capillary‐like structures that support endothelial alignment, cytoskeletal organization, and pericyte‐endothelial‐glioma tri‐cultures.

Andisols from Tondano Area, North Sulawesi: Properties and Classification

open access: yesJournal of Tropical Soils, 2008
Three pedons of Andisol (TN-1, TN-2 and TN-3) developed from young volcanic materials of the Lokon, Soputan, and Lengkoan volcanoes respectively in the Tondano area, North Sulawesi, were studied in the field, and 18 soil samples were analysed in the ...

Simultaneous Measurement of Thermal Expansion and Thermo‐Optic Effect in Solids Using Terahertz Spectroscopy

open access: yesAdvanced Optical Materials, EarlyView.
Thermal expansion and the thermo‐optic effect in solids are closely coupled, reflecting concurrent changes in mass density and polarizability. Using echo‐resolved THz spectroscopy, we simultaneously determine sub‐micrometer thermal expansion and complex refractive index changes of MgO and Al2O3 from 10–325 K. The analysis yields both the coefficient of

Andisols Derived From Acid Pyroclastic Liparite Tuff : Their Properties and Their Management Strategy for Agricultural Development [PDF]

open access: yes, 2011
The characterizations of Andisols from acid pyroclastic liparite tuff have been studied. Six soil profiles were made in the field, and 29 soil samples were taken for chemical, mineralogical and physical analyses in laboratory.

Conformable Microelectrode Arrays Integrated with a Scoop‐Shaped Slide‐Well for Dynamic Electrophysiological Profiling of Patient‐Derived Cardiac Organoids

open access: yesAdvanced Science, EarlyView.
A flexible, ultrathin multi‐channel microelectrode array (MEA) conformally integrated onto a curved slide‐well enables stable electrical interfacing with 3D cardiac organoids. The geometry‐guided self‐alignment allows simultaneous recording of extracellular field potentials and contractile motion from irregular, beating tissues.

Phosphorus desorbability in soils with andic properties from the Azores, Portugal Desorção de fósforo em solos com propriedades ândicas do Arquipélago dos Açores (Portugal)

open access: yesRevista de Ciências Agrárias, 2009
Desorbability of phosphorus (P des) at P sorption maxima in eighteen horizons (surface and subsurface) of soils with andic properties from the Azores, Portugal, was determined by eight successive extractions using distilled water (H2O), calcium chloride (

Putrescine production by Lactococcus lactis subsp. cremoris CECT 8666 is reduced by NaCl via a decrease in bacterial growth and the repression of the genes involved in putrescine production [PDF]

open access: yes, 2016
The reduction of NaCl in food is a public health priority; high NaCl intakes have been associated with serious health problems. However, it is reported that reducing the NaCl content of cheeses may lead to an increase in the content of biogenic amines ...
