Variações dos carboidratos de reserva de sementes de Caesalpinia echinata (pau-brasil) armazenadas sob diferentes temperaturas

open access: yesHoehnea
Dentre os carboidratos de reserva de sementes destacam-se o amido, a sacarose e os oligossacarídeos galactosilados, que além da função de reserva, podem atuar na estabilidade das membranas durante a dessecação e a retomada do crescimento embrionário ...

Satellite Imagery Recording the Process and Pattern of Winter Temperature Field in Yangtze Estuary Interrupted by a Cold Wave

open access: yesAtmosphere, 2023
Sea surface temperature (SST) is a key marine ecological metric. An optimized split-window algorithm was used to invert the Yangtze Estuary’s temperature field during a cold wave process. Additionally, MODIS SST inversion results were used to explore the

Effects of Cold Periods on the Stimulus-Response System of Phycomyces [PDF]

open access: yes, 1970
The sporangiophores of Phycomyces do not exhibit phototropic responses when growth is arrested reversibly by cooling to 1°C. Unilateral UV stimuli (254 nm) applied during cold periods are stored for at least 2 hr and produce tropic responses away from ...

Cold Temperature Adaptation and Growth of Microorganisms

open access: yesJournal of Food Protection, 1997
Most microorganisms must accommodate a variety of changing conditions and stresses in their environment in order to survive and multiply. Because of the impact of temperature on all reactions of the cell, adaptations to fluctuations in temperature are possibly the most common. Widespread in the environment and well-equipped for cold temperature growth,

Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

open access: yesMolecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

Cold water interception cooling technology for surrounding rock of heat-damaged mine

open access: yesMeikuang Anquan, 2023
In order to alleviate the problem of mine thermal damage, this paper proposes to put cold water pipe into the surrounding rock of roadway, and reduce the temperature of surrounding rock by intercepting the high temperature through the cold water pipe ...

The Effect of Ambient Temperature on Cold Start Urban Traffic Emissions for a Real World SI Car [PDF]

open access: yes, 2004
The influence of ambient temperature on exhaust emissions for an instrumented Euro 1 SI car was determined. A real world test cycle was used, based on an urban drive cycle that was similar to the ECE urban drive cycle.

How Cold is Cold Dark Matter?

open access: yes, 2014
If cold dark matter consists of particles, these must be non-interacting and non-relativistic by definition. In most cold dark matter models however, dark matter particles inherit a non-vanishing velocity dispersion from interactions in the early ...

Measuring and manipulating the temperature of cold molecules trapped on a chip [PDF]

open access: yesPhysical Review A, 2015
We demonstrate the measurement and manipulation of the temperature of cold CO molecules in a microchip environment. Through the use of time-resolved spatial imaging, we are able to observe the phase-space distribution of the molecules, and hence deduce the corresponding temperature.

Inhibitor of DNA binding‐1 is a key regulator of cancer cell vasculogenic mimicry

open access: yesMolecular Oncology, EarlyView.
Elevated expression of transcriptional regulator inhibitor of DNA binding 1 (ID1) promoted cancer cell‐mediated vasculogenic mimicry (VM) through regulation of pro‐angiogenic and pro‐cancerous genes (e.g. VE‐cadherin (CDH5), TIE2, MMP9, DKK1). Higher ID1 expression also increased metastases to the lung and the liver.
