Numerous and extensive 'Stone Walled Sites' have been identified in southern African Iron Age landscapes. Appearing from around 1200 CE, and showing considerable variability in size and form, these settlements are named after...
Attachment representations and socio-emotional difficulties in alternative care
Attachment has been assessed in children living in alternative care (AC) settings, such as Residential Homes (RC) and Foster Care (FC). However, no study has been conducted to compare attachment styles in residential, foster and...

Seizure onset zone classification based on imbalanced iEEG with data augmentation.
Objective. Identifying the seizure onset zone (SOZ) in patients with focal epilepsy is the critical information required for surgery. However, collecting this information is challenging, time-consuming, and subjective. Some...
Relationship between fiducial points on the peripheral and central blood pressure waveforms
Ye Li, Antoine Guilcher, Peter H Charlton, Samuel Vennin, Jordi Alastruey, Phil Chowienczyk
Mar 01, 2021
Central systolic blood pressure (cSBP, the peak of the central waveform) is usually regarded as the determinant of peripheral systolic blood pressure with amplification of peripheral systolic blood pressure (pSBP) measured with...

Vascular smooth muscle cell phenotypic switching and plaque stability
Vascular smooth muscle cells (VSMCs) play important and varied roles in the development and progression of atherosclerosis. VSMCs form the medial layer of arteries where they maintain vessel tone via their contractile function....
Acquiring Wearable Photoplethysmography Data in Daily Life
The photoplethysmogram (PPG) signal is widely measured by smart watches and fitness bands for heart rate monitoring. New applications of the PPG are also emerging, such as to detect irregular heart rhythms, track infectious...
Placental secretome characterization identifies candidates for pregnancy complications
Tina Napso, Xiaohui Zhao, Marta Ibañez Lligoña, Ionel Sandovici, Richard G. Kay, Amy L. George, Fiona M. Gribble, Frank Reimann, Claire L. Meek, Russell S. Hamilton, Amanda N. Sferruzzi-Perri

Abstract: Alterations in maternal physiological adaptation during pregnancy lead to complications, including abnormal birthweight and gestational diabetes. Maternal adaptations are driven by placental hormones, although the full...
Assessing mental stress from the photoplethysmogram
OBJECTIVE: Mental stress is detrimental to cardiovascular health, being a risk factor for coronary heart disease and a trigger for cardiac events. However, it is not currently routinely assessed. The aim of this study was to...
Mortality cost of sex-specific parasitism in wild bird populations
Jose O. Valdebenito, András Liker, Naerhulan Halimubieke, Jordi Figuerola, Tamas Szekely
Dec 02, 2020
Sex-specific mortality is frequent in animals although the causes of different male versus female mortalities remain poorly understood. Parasitism is ubiquitous in nature with widespread detrimental effects to hosts, making...
Integrating cell morphology with gene expression and chemical structure to aid mitochondrial toxicity detection.
Srijit Seal, Jordi Carreras-Puigvert, Maria-Anna Trapotsi, Hongbin Yang, Ola Spjuth, Andreas Bender
Sep 23, 2022
Mitochondrial toxicity is an important safety endpoint in drug discovery. Models based solely on chemical structure for predicting mitochondrial toxicity are currently limited in accuracy and applicability domain to the chemical...
Regulated fluctuations in Nanog expression mediate cell fate decisions in embryonic stem cells
Tibor Kalmar, Chea Lim, Penelope Hayward, Silvia Muñoz-Descalzo, Jennifer Nichols, Jordi Garcia-Ojalvo, Alfonso Martinez Arias
Jul 01, 2009
There is evidence that pluripotency of mouse embryonic stem (ES) cells is associated with the activity of a network of transcription factors with Sox2, Oct4, and Nanog at the core. Using fluorescent reporters for the expression...
Influence of mental stress on the pulse wave features of photoplethysmograms.
Mental stress is a major burden for our society. Invasive and non-invasive methods have been proposed to monitor and quantify it using various sensors on and off body. In this Letter, the authors investigated the use of the arm...
Seasonal variation in sex-specific immunity in wild birds
Jose O. Valdebenito, Naerhulan Halimubieke, A Z Lendvai, Jordi Figuerola, Götz Eichhorn, Tamas Szekely
Jan 14, 2021
Whilst the immune system often varies seasonally and exhibits differences between males and females, the general patterns in seasonality and sex differences across taxa have remained controversial. Birds are excellent model...
Modeling arterial pulse waves in healthy aging
Peter H Charlton, Jorge Mariscal Harana, Samuel Vennin, Ye Li, Phil Chowienczyk, Jordi Alastruey
Sep 11, 2020
The arterial pulse wave (PW) is a rich source of information on cardiovascular (CV) health. It is widely measured by both consumer and clinical devices. However, the physical determinants of the PW are not yet fully understood...
