Nature, 1948 ACCORDING to the definition of Barclay et al.1, the ‘renal threshold' can be expressed as a rate of tubular reabsorption per 100 c.c. glomerular filtrate. Thus where T is ‘threshold', Rx is the amount of the ‘threshold substance' reabsorbed by the tubules (mgm./min.), and C is clearance of inulin, or mannitol.

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network
FEBS Letters, EarlyView.Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

An Embedded Application for Degraded Text Recognition
EURASIP Journal on Advances in Signal Processing, 2005 This paper describes a mobile device which tries to give the blind or visually impaired access to text information. Three key technologies are required for this system: text detection, optical character recognition, and speech synthesis. Blind users and

THORS: An Efficient Approach for Making Classifiers Cost-Sensitive
IEEE Access, 2019 In this paper, we propose an effective THresholding method based on the Order Statistic, called THORS, to convert an arbitrary scoring-type classifier, which can induce a continuous cumulative distribution function of the score, into a cost-sensitive one.

Frontiers in Earth Science, 2020 This article focuses on new virtual advances to solve technical problems usually encountered by paleontologists when using X-ray computed tomography (XCT), such as (i) the limited scanning envelope (i.e., field of view of CT systems/machines) to acquire ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry
FEBS Letters, EarlyView.EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Journal of Medical Signals and Sensors, 2016 In this paper, an efficient algorithm is proposed for detection of vertical root fractures (VRFs) in periapical (PA), and cone-beam computed tomography (CBCT) radiographs of nonendodontically treated premolar teeth.

An improvement in the moment-preserving thresholding method [PDF]
, 2010 [[abstract]]Thresholding is frequently used for image segmentation. One of the most popular approach to thresholding is the moment-preserving thresholding method proposed by Tsai in 1985.

Color image segmentation using multilevel thresholding-cooperative bacterial foraging algorithm
, 2015 Multilevel thresholding is of great importance in the fields of image segmentation techniques. This paper proposes multilevel thresholding for color image segmentation using cooperative bacterial foraging algorithm (CBFA), which combined bacterial chemo ...

Translophagy—A potential link between autophagy impairment and translational errors
FEBS Letters, EarlyView.Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.
