After correction for postmenstrual age at MRI, the pre- and postoperative maturation score was lower in patients compared to controls (preoperative P = 0.01, postoperative P = 0.03) and increased between pre- and postoperative assessment (P ≤ 0.001). Brain maturation scores did not correlate with neurodevelopmental outcome at 1 year, when corrected for socioeconomic status and postmenstrual age at MRI. This study confirms delayed brain maturation in children with congenital heart disease, and despite neonatal cardiac bypass surgery followed by postoperative intensive care medicine brain maturation is ongoing. We encourage further investigation in outcome prediction in this population, potentially by combining more advanced MRI measures with clinical methods.Medullary thyroid carcinoma (MTC) is a rare neuroendocrine neoplasm of the parafollicular thyroid C cells. Although somatostatin receptors are expressed by MTCs, treatment with octreotide has shown poor efficacy, whereas recently pasireotide has demonstrated antiproliferative effects in persistent postoperative MTCs. Aim of this study was to test the effects of octreotide and pasireotide on MTC cells proliferation, cell cycle proteins expression, MAPK activation, apoptosis, calcitonin secretion, migration and invasion in TT cell line as well as in primary MTC cultured cells. Our results showed that both octreotide and pasireotide reduced TT cell proliferation (-35.2 ± 12.1%, p less then 0.001, and -25.3 ± 24.8%, p less then 0.05, at 10-8 M, respectively), with concomitant inhibition of ERK phosphorylation and cyclin D1 expression. This cytostatic effect was accompanied by a proapoptotic action, with an increase of caspase3/7 activity of 1.5-fold. Moreover, both octreotide and pasireotide inhibited cell migration (-50.9 ± 11.3%, p less then 0.01, and -40.5 ± 17%, p less then 0.05, respectively) and invasion (-61.3 ± 35.1%, p less then 0.05, and -49.7 ± 18%, p less then 0.01, respectively). No effect was observed on calcitonin secretion. We then tried to extend these observations to primary cultures (n = 5). Octreotide and/or pasireotide were effective in reducing cells proliferation in 3 out of 5 tumors, and to induce cell apoptosis in 1 out of 3 MTCs. Both octreotide and pasireotide were able to reduce cell migration in all MTC tested. SST2, SST3 and SST5 were expressed in all MTC, with a tendency to increased expression of SST2 in RET mutated vs wild type MTCs. In agreement, inhibition of mutated RET in TT cells reduced SST2 expression. In conclusion, we demonstrated that octreotide and pasireotide inhibited cell proliferation and invasiveness in a subset of MTC, supporting their potential use in the control of tumor growth.We recently described X-linked acrogigantism (X-LAG), a condition of early childhood-onset pituitary gigantism associated with microduplications of the GPR101 receptor. The expression of GPR101 in hyperplastic pituitary regions and tumors in X-LAG patients, and GPR101's normally transient pituitary expression during fetal development, suggest a role in the regulation of growth. Nevertheless, little is still known about GPR101's physiological functions, especially during development. By using zebrafish models, we investigated the role of gpr101 during embryonic development and somatic growth. Transient ectopic gpr101 expression perturbed the embryonic body plan but did not affect growth. Loss of gpr101 led to a significant reduction in body size that was even more pronounced in the absence of maternal transcripts, as well as subfertility. These changes were accompanied by gastrulation and hypothalamic defects. In conclusion, both gpr101 loss- and gain-of-function affect, in different ways, fertility, embryonic patterning, growth and brain development.This review summarises the recent evidence on preoperative therapeutic strategies in pancreatic cancer and discusses the rationale for an imminent need for a personalised therapeutic approach in non-metastatic disease. The molecular diversity of pancreatic cancer and its influence on prognosis and treatment response, combined with the failure of 'all-comer' treatments to significantly impact on patient outcomes, requires a paradigm shift towards a genomic-driven approach. This is particularly important in the preoperative, potentially curable setting, where a personalised treatment allocation has the substantial potential to reduce pancreatic cancer mortality.The receptor-binding domain (RBD) of the SARS-CoV-2 spike protein is a commonly used antigen for serology assays critical to determining the extent of SARS-CoV-2 exposure in the population.  https://www.selleckchem.com/products/r-hts-3.html  Different versions of the RBD protein have been developed and utilized in assays, with higher sensitivity attributed to particular forms of the protein. To improve the yield of these high-sensitivity forms of RBD and support the increased demand for this antigen in serology assays, we investigated several protein expression variables including DNA elements such as promoters and signal peptides, cell culture expression parameters, and purification processes. Through this investigation, we developed a simplified and robust purification strategy that consistently resulted in high levels of the high-sensitivity form of RBD and demonstrated that a carboxyterminal tag is responsible for the increased sensitivity in the ELISA. These improved reagents and processes produce high-quality proteins which are functional in serology assays and can be used to investigate seropositivity to SARS-CoV-2 infection.While the discovery of antibiotics has made a huge contribution to medicine, bacteria that are resistant to many antibiotics pose new challenges to medicine. Antimicrobial peptides (AMPs), a new kind of antibiotics, have attracted people's attention because they are not prone to drug resistance. In this study, glutathione transferase (GST) was used as a fusion partner to recombinantly expressed rat lung surfactant protein B precursor (proSP-B) in E. coli pLySs. Cck-8 evaluated the cytotoxicity of the fusion protein and calculated its 50% inhibitory concentration (IC50). The purified peptides showed broad-spectrum antibacterial activity using filter paper method and MIC, and propidium iodide (PI) was used to explore the antibacterial mechanism against Staphylococcus aureus. In addition, the pEGFP-N2-proSP-B vector was constructed to explore the localization of proSP-B in CCL-149 cells. We found that proSP-B has obvious antibacterial activity against Gram-positive bacteria, Gram-negative bacteria and fungi, and has broad-spectrum antibacterial activity.
