New Horizons: Revival of Lipoprotein (a) as a Risk Factor for Cardiovascular Disease.
THE JOURNAL OF CLINICAL ENDOCRINOLOGY AND METABOLISM - 23 Nov 2022
The status of lipoprotein (a) [Lp(a)] as a cardiovascular risk factor has been resurrected by advances in genetics. Mendelian randomization studies show a causal link of Lp(a) with coronary artery disease (CAD), peripheral artery disease (PAD), and calcific aortic valve stenosis (CAVS). The genetics of Lp(a) is complex and extends beyond the kringle-IV type 2, as it is also dependent on ancestr...

γH2AX in mouse embryonic stem cells: Distribution during differentiation and following γ-irradiation.
CELLS & DEVELOPMENT - 11 Nov 2023
Phosphorylated histone H2AX (γH2AX) represents a sensitive molecular marker of DNA double-strand breaks (DSBs) and is implicated in stem cell biology. We established a model of mouse embryonic stem cell (mESC) differentiation and examined the dynamics of γH2AX foci during the process. Our results revealed high numbers of γH2AX foci in undifferentiated mESCs, decreasing as the cells differentiat...
Establishing international optimal cut-offs of waist-to-height ratio for predicting cardiometabolic risk in children and adolescents aged 6-18 years.
BMC MEDICINE - 15 Nov 2023
Waist-to-height ratio (WHtR) has been proposed as a simple and effective screening tool for assessing central obesity and cardiometabolic risk in both adult and pediatric populations. However, evidence suggests that the use of a uniform WHtR cut-off of 0.50 may not be universally optimal for pediatric populations globally. We aimed to determine the optimal cut-offs of WHtR in children and adole...

Poor sleep and shift work associate with increased blood pressure and inflammation in UK Biobank participants.
NATURE COMMUNICATIONS - 04 Nov 2023
Disrupted circadian rhythms have been linked to an increased risk of hypertension and cardiovascular disease. However, many studies show inconsistent findings and are not sufficiently powered for targeted subgroup analyses. Using the UK Biobank cohort, we evaluate the association between circadian rhythm-disrupting behaviours, blood pressure (SBP, DBP) and inflammatory markers in >350,000 adult...
Top-down control of vestibular inputs by the dorsolateral prefrontal cortex.
EXPERIMENTAL BRAIN RESEARCH - 01 Dec 2023
The vestibular apparatus provides spatial information on the position of the head in space and with respect to gravity. Low-frequency sinusoidal galvanic vestibular stimulation (sGVS), a means of selectively changing the firing of vestibular afferents, induces a frequency-dependent perception of sway and, in some individuals, induces nausea. Given that vestibular afferents project to the insula...
Multiple Myeloma-Derived Circulating Extracellular Vesicles Affect Normal Human Stromal Cell Behaviour and Promote Tumor Progression: A Multi-Omic Approach
BLOOD - 15 Nov 2022
Extracellular vesicles (EVs) are secreted in the extracellular space, can travel through the blood stream and are transferred to target (stromal) cells. This makes EVs an important means of cell-to-cell communication both at local and distant sites (metastasis). EVs can reprogram signalling pathways in stromal cells promoting the formation of a supportive tumour microenvironment (TME) and pre-m...
