The mammalian liver has a remarkable capacity for repair following injury. Removal of up to two-third of liver mass results in a series of events that include extracellular matrix remodeling, coordinated hepatic cell cycle re-entry, restoration of liver mass and tissue remodeling to return the damaged liver to its normal state. Although there has been considerable advancement of our knowledge concerning the regenerative capacity of the mammalian liver, many outstanding questions remaining, such as: how does the regenerating liver stop proliferating when appropriate mass is restored and how do these mechanisms relate to normal regulation of organ size during development? Hippo pathway has been proposed to be central in mediating both events: organ size control during development and following regeneration...

Sodium taurocholate cotransporting polypeptide (NTCP) is encoded by the gene SLC10A1 and expressed in the basolateral membrane of the hepatocyte, functioning to uptake bile acids from plasma. Although SLC10A1 has been cloned and NTCP function studied intensively for years, clinical description of NTCP deficiency remains rather limited. This study reported the genotypic and phenotypic features of two neonatal patients with NTCP deficiency. They both presented with neonatal indirect hyperbilirubinemia and remarkable hypercholanemia, and harbored the SLC10A1 variants c...

OBJECTIVE: Although non-steroidal anti-inflammatory drugs (NSAIDs) are the current standard therapy for the treatment of patent ductus arteriosus (PDA), many neonates have contraindications to receiving or may fail NSAID therapy. To avoid surgical ligation, these patients may benefit from an alternative therapy. The objective of this research is to report the efficacy and safety of acetaminophen for the treatment of PDA in a cohort of premature neonates. METHODS: Demographics and clinical course were retrospectively evaluated for all neonates admitted during the study period who received acetaminophen for the treatment of PDA...

BACKGROUND: Clinical and experimental data indicate that neonates are sensitive to the CO2 pneumoperitoneum. An impaired splanchnic perfusion during laparoscopy in adults has been reported. We recently confirmed that intravenous colloids improve macrocirculatory function in neonates. We aimed to determine the impact of CO2 pneumoperitoneum on the perfusion of splanchnic organs in the young including effects of colloid application. METHODS: Male piglets (n = 25) were divided into four groups: (1) neonatal controls, (2) neonates with crystalloid restitution, (3) neonates with colloidal restitution, and (4) adolescents with crystalloid restitution...

A critical challenge in producing an antibody-based assay with the highest reproducibility and sensitivity is the strategy to immobilise antibodies to solid phase. To date, numerous methods of antibody immobilisation were reported but each was subjected to its advantages and limitations. The current study proposes a new potential antibody binding protein, the human neonatal Fc receptor. This protein has shown its high affinity to the Fc of antibody either in vivo or in vitro. Human neonatal Fc receptor is a heterodimer constructed by p51 α-heavy chain and β2-microglobulin light chain; however, the binding sites towards the antibody are located in the p51 α-heavy chain...

BACKGROUND: The United States currently has an opioid use disorder epidemic and research evaluating ways to minimize the use of opioids post-surgery are needed. One of these options is intravenous (IV) acetaminophen. If the use of preoperative IV acetaminophen was found to be effective for cesarean delivery, this would be beneficial for both the mother and breastfeeding neonate. OBJECTIVE: The primary study objective was to see if maternal opioid use was significantly less in the postoperative period for the study group that received 1 gram of IV acetaminophen preoperatively compared with a control group that received placebo...

The creation of in vitro functional hepatic tissue simulating micro-environmental niche of native liver is a keen area of research due to its demand in bioartificial liver (BAL) and cell-based tissue engineering. Here, we investigated the potential of novel blend (BA) silk scaffold fabricated by blending mulberry (Bombyx mori, BM) silk fibroin with cell adhesion motif (RGD) rich non-mulberry (Antheraea assamensis, AA) silk fibroin in generating a functional liver construct. Three-dimensional (3D) porous silk scaffolds (BM, AA and BA) were physico-chemically characterized and functionally evaluated using human hepatocarcinoma cells (HepG2) and primary neonatal rat hepatocytes...

Liver tissue engineering has emerged as a promising approach in organ transplantation, but has been hampered by the lack of a reliable and readily available cell source. Induced pluripotent cells (hiPSC) have been highlighted a desirable source, due to their differentiation potential, ability to self-renew and the possibility of making patient specific cells. We developed a decellularization protocol that efficiently removes cellular material, while retaining extracellular matrix components. Subsequently, hiPSC were differentiated on the decellularized human liver matrix (hDLM) scaffolds using an established hepatic differentiation protocol...

Transient congenital hypothyroidism (CH) refers to a temporary deficiency of thyroid hormone identified after birth, with low thyroxine (T4) and elevated thyrotropin (TSH), which later recovers to improved thyroxine production, typically in first few months of infancy. Approximately 17% to 40% of children diagnosed with CH by newborn screening (NBS) programs were later determined to have transient hypothyroidism. Causes of transient CH are prematurity, iodine deficiency, maternal thyrotropin receptor blocking antibodies, maternal intake of anti-thyroid drugs, maternal or neonatal iodine exposure, loss of function mutations and hepatic hemangiomas...

Exposure to supraphysiological concentrations of oxygen (hyperoxia) leads to bronchopulmonary dysplasia (BPD), one of the most common pulmonary morbidities in preterm neonates, which is more prevalent in males than females. Beta-naphthoflavone (BNF) is protective against hyperoxic lung injury in adult and neonatal wild type (WT) mice and in and mice lacking Cyp1a1gene. In this investigation, we tested the hypothesis that BNF treatment will attenuate neonatal hyperoxic lung injury in WT and Cyp1a2-/- mice, and elucidated the effect of sex-specific differences...

Hepatitis is the most common liver diseases in the Pakistan caused by blood-borne infection of HCV. Viral transmission is frequent through blood contact. Vertical transmission is transfer of disease from mother to infant. The women who are infected with hepatitis C virus RNA are at high risk of infecting their babies. Actual transmission occurs during labor and at time of delivery when blood of both mother and neonate is in contact with each other. Vertical transmission rate is lowered when mother is HCV RN A negative...
