Management of Multi Organ Dysfunction in Neonatal Encephalopathy.

Mary O'Dea, Deirdre Sweetman, Sonia Lomeli Bonifacio, Mohamed El-Dib, Topun Austin, Eleanor J Molloy,

Neonatal Encephalopathy (NE) describes neonates with disturbed neurological function in the first post-natal days of life. NE is an overall term that does not specify the etiology of the encephalopathy although it often involves hypoxia-ischaemia. In NE, although neurological dysfunction is part of the injury and is most predictive of ... Read more >>

Effects of insulin like growth factors on early embryonic chick limb myogenesis.

Rabeea Hazim Mohammed, Helen Anderton, John Michael Brameld, Dylan Sweetman,

Limb muscles derive from pax3 expressing precursor cells that migrate from the hypaxial somite into the developing limb bud. Once there they begin to differentiate and express muscle determination genes such as MyoD. This process is regulated by a combination of inductive or inhibitory signals including Fgf18, retinoic acid, HGF, ... Read more >>

LIM kinase function and renal growth: Potential role for LIM kinases in fetal programming of kidney development.

Alexander J Sparrow, Dylan Sweetman, Simon J M Welham,

Maternal dietary restriction during pregnancy impairs nephron development and results in offspring with fewer nephrons. Cell turnover in the early developing kidney is altered by exposure to maternal dietary restriction and may be regulated by the LIM-kinase family of enzymes. We set out to establish whether disturbance of LIM-kinase activity ... Read more >>

Neonatal acute kidney injury - Severity and recovery prediction and the role of serum and urinary biomarkers.

Deirdre U Sweetman,

Neonatal acute kidney injury is common, in part due to incomplete renal maturation and also due to frequent exposure to risk factors for acute kidney injury such as perinatal asphyxia, extracorporeal-membrane-oxygenation, cardiac surgery, sepsis, prematurity and nephrotoxicity. However the current method by which acute kidney injury is diagnosed is sub-optimal ... Read more >>

Perinatal Asphyxia and Erythropoietin and VEGF: Serial Serum and Cerebrospinal Fluid Responses.

Deirdre U Sweetman, Chike Onwuneme, William R Watson, John F A Murphy, Eleanor J Molloy,

Infants with neonatal encephalopathy (NE) of hypoxic-ischaemic origin are at risk of oxidative and ischaemia-reperfusion injury, which may induce abnormal inflammatory responses involving excessive cytokine production and release in serum and cerebrospinal fluid (CSF). Systemic inflammation is found in infants with NE, and we therefore were interested in cytokines associated ... Read more >>

Deirdre U Sweetman, Chike Onwuneme, William R Watson, Amanda O'Neill, John F A Murphy, Eleanor J Molloy,

Perinatal asphyxia is associated with multi-organ injury including acute kidney injury (AKI). New urinary biomarkers may detect more subtle renal injury.Urinary biomarkers (albumin, beta-2 microglobulin, cystatin-C, epidermal growth factor, neutrophil gelatinase-associated lipocalin, osteopontin, uromodulin) were serially measured from days 1 to 7 in term infants with perinatal asphyxia and controls ...

K D Sinclair, K M D Rutherford, J M Wallace, J M Brameld, R Stöger, R Alberio, D Sweetman, D S Gardner, V E A Perry, C L Adam, C J Ashworth, J E Robinson, C M Dwyer,

The concept that postnatal health and development can be influenced by events that occur in utero originated from epidemiological studies in humans supported by numerous mechanistic (including epigenetic) studies in a variety of model species. Referred to as the 'developmental origins of health and disease' or 'DOHaD' hypothesis, the primary ... Read more >>

Actin depolymerization is associated with meiotic acceleration in cycloheximide-treated ovine oocytes.

Sergio D German, Joon-Hee Lee, Keith H Campbell, Dylan Sweetman, Ramiro Alberio,

Oocytes treated with the protein synthesis inhibitor cycloheximide (CHX) arrest at the germinal vesicle (GV) stage and undergo accelerated GV breakdown (GVBD) after CHX is removed. However, little is known about the underlying mechanism of accelerated meiotic maturation. Here, we investigated this mechanism and found that oocytes released from CHX ... Read more >>

Ovine induced pluripotent stem cells are resistant to reprogramming after nuclear transfer.

Sergio D German, Keith H S Campbell, Elisabeth Thornton, Gerry McLachlan, Dylan Sweetman, Ramiro Alberio,

Induced pluripotent stem cells (iPSCs) share similar characteristics of indefinite in vitro growth with embryonic stem cells (ESCs) and may therefore serve as a useful tool for the targeted genetic modification of farm animals via nuclear transfer (NT). Derivation of stable ESC lines from farm animals has not been possible, ... Read more >>

The effects of age upon the expression of three miRNAs in muscle stem cells isolated from two different porcine skeletal muscles.

Zoe Redshaw, Dylan Sweetman, Paul T Loughna,

Aging is associated with a gradual loss of skeletal muscle mass and an impaired ability of this tissue to compensate for trauma. Studies in rodents and humans have also shown that resident stem cells within muscle have a reduced ability to proliferate and differentiate. In this study muscle stem cells ... Read more >>

Interactions between FGF18 and retinoic acid regulate differentiation of chick embryo limb myoblasts.

Gi Fay Mok, Ryan Cardenas, Helen Anderton, Keith H S Campbell, Dylan Sweetman,

During limb development Pax3 positive myoblasts delaminate from the hypaxial dermomyotome of limb level somites and migrate into the limb bud where they form the dorsal and ventral muscle masses. Only then do they begin to differentiate and express markers of myogenic commitment and determination such as Myf5 and MyoD. ... Read more >>
