A Rare Case of Rhabdoid Pancreatic Carcinoma: Prolonged Disease-Free Survival Following Upfront Resection and Adjuvant Chemotherapy.

The rhabdoid subtype of undifferentiated pancreatic carcinoma is rarely reported. The clinical course of this disease is therefore poorly understood, although it is apparently an aggressive malignancy. We herein discuss the case of a 69-year-old man presenting with a rapidly enlarging mass of the pancreatic body and tail who was diagnosed with locally advanced SMARCB1-deficient undifferentiated pancreatic carcinoma with rhabdoid features, treated with radical resection and adjuvant chemotherapy, and has achieved 18-month disease-free survival ongoing at the time of article publication.

Refining stereotactic body radiation therapy as a bridge to transplantation for hepatocellular carcinoma: An institutional experience.

Background: Stereotactic body radiotherapy (SBRT) has been established as a safe and effective treatment for hepatocellular carcinoma (HCC). Currently, there are no consensus guidelines to advise optimal patient selection and radiotherapy planning parameters to minimise the risk of surgical and medical complications after liver transplant (LT) in patients who have had prior SBRT for HCC, whilst optimising treatment benefit.

Methods: We performed a retrospective analysis of all adult patients who received liver SBRT as a bridge to LT at a tertiary institution between 2017 and 2019.

Near-Fatal Hepatic Complication After Cardiac Catheter Ablation.

Radiofrequency cardiac ablation is increasingly performed for the management of dysrhythmias. Bleeding is a well-known complication of this procedure. We present a rare case of a near-fatal iatrogenic hepatic hemorrhage after cardiac catheter ablation.

Age Effects Aggressive Behavior: RNA-Seq Analysis in Cattle with Implications for Studying Neoteny Under Domestication.

The reactive type of aggression is regulated mostly by the brain's prefrontal cortex; however, the molecular changes underlying aggressiveness in adults have not been fully characterized. We used an RNA-seq approach to investigate differential gene expression in the prefrontal cortex of bovines from the aggressive Lidia breed at different ages: young three-year old and adult four-year-old bulls. A total of 50 up and 193 down-regulated genes in the adult group were identified.

Long term outcomes of hepatic resection following orthotopic liver transplant.

Background: Liver resection is sometimes used as a graft saving procedure following orthotopic liver transplantation.

Methods: In this single centre retrospective cohort study, 12 adult patients underwent resection over a 20 year period, including recipients of split livers and second grafts.

Results: Indications for resection were vascular (portal vein obstruction and hepatic artery thrombus), biliary (ischaemic cholangiopathy, chronic biliary obstruction, biliary-vascular fistula and biloma) and recurrence of disease (primary sclerosing cholangitis [PSC] and hepatocellular carcinoma [HCC]).

Gene expression profiles underlying aggressive behavior in the prefrontal cortex of cattle.

Background: Aggressive behavior is an ancient and conserved trait, habitual for most animals in order to eat, protect themselves, compete for mating and defend their territories. Genetic factors have been shown to play an important role in the development of aggression both in animals and humans, displaying moderate to high heritability estimates. Although such types of behaviors have been studied in different animal models, the molecular architecture of aggressiveness remains poorly understood.

Capturing the Effects of Domestication on Vocal Learning Complexity.

Domesticated and vocal learning species can serve as informative model organisms for the reduction of reactive aggression and emergence of speech in our lineage. Amidst mounting evidence that domestication modifies vocal repertoires across different species, we focus on the domesticated Bengalese finch, which has a more complex song than the wild-type white-rumped munia. Our explanation for this effect revolves around the glutamate neurotransmitter system.

Dosage analysis of the 7q11.23 Williams region identifies as a major human gene patterning the modern human face and underlying self-domestication.

We undertook a functional dissection of chromatin remodeler BAZ1B in neural crest (NC) stem cells (NCSCs) from a uniquely informative cohort of typical and atypical patients harboring 7q11.23 copy number variants. Our results reveal a key contribution of BAZ1B to NCSC in vitro induction and migration, coupled with a crucial involvement in NC-specific transcriptional circuits and distal regulation.

Glutamate receptors in domestication and modern human evolution.

There has been a recent resurgence of interest in the hypothesis that anatomically modern humans and domesticated species have followed convergent evolutionary paths. Here, we review results from domestication and modern-human evolutionary studies in order to evaluate evidence for shared changes to neurotransmission across these species. We compare genomic and, where available, brain-expression differences across 488 neurotransmitter receptor genes in 14 domesticated species and modern humans relative to their wild and archaic counterparts.

Names and their meanings: A dual-process account of proper-name encoding and retrieval.

The ability to pick out a unique entity with a proper name is an important component of human language. It has been a primary focus of research in the philosophy of language since the nineteenth century. Brain-based evidence has shed new light on this capacity, and an extensive literature indicates the involvement of distinct fronto-temporal and temporo-occipito-parietal association cortices in proper-name retrieval.

Increasing Community Resilience Through Improved Lifeline Infrastructure Performance.

The concept of community resilience is complex and multidimensional, relying on engineering and other disciplines to help communities break the cycle of destruction and recovery and reduce the impacts of earthquakes and other hazards. This article presents proposed prioritized actions to improve lifeline infrastructure resilience based on an assessment of lifeline infrastructure performance commissioned and funded by the National Institute of Standards and Technology (NIST).

Nab3's localization to a nuclear granule in response to nutrient deprivation is determined by its essential prion-like domain.

Ribonucleoprotein (RNP) granules are higher order assemblies of RNA, RNA-binding proteins, and other proteins, that regulate the transcriptome and protect RNAs from environmental challenge. There is a diverse range of RNP granules, many cytoplasmic, which provide various levels of regulation of RNA metabolism. Here we present evidence that the yeast transcription termination factor, Nab3, is targeted to intranuclear granules in response to glucose starvation by Nab3's proline/glutamine-rich, prion-like domain (PrLD) which can assemble into amyloid in vitro.

Self-domestication in Homo sapiens: Insights from comparative genomics.

This study identifies and analyzes statistically significant overlaps between selective sweep screens in anatomically modern humans and several domesticated species. The results obtained suggest that (paleo-)genomic data can be exploited to complement the fossil record and support the idea of self-domestication in Homo sapiens, a process that likely intensified as our species populated its niche. Our analysis lends support to attempts to capture the "domestication syndrome" in terms of alterations to certain signaling pathways and cell lineages, such as the neural crest.

The hnRNP-like Nab3 termination factor can employ heterologous prion-like domains in place of its own essential low complexity domain.

Many RNA-binding proteins possess domains with a biased amino acid content. A common property of these low complexity domains (LCDs) is that they assemble into an ordered amyloid form, juxtaposing RNA recognition motifs in a subcellular compartment in which RNA metabolism is focused. Yeast Nab3 is one such protein that contains RNA-binding domains and a low complexity, glutamine/proline-rich, prion-like domain that can self-assemble.

Determinants of Amyloid Formation for the Yeast Termination Factor Nab3.

Low complexity protein sequences are often intrinsically unstructured and many have the potential to polymerize into amyloid aggregates including filaments and hydrogels. RNA-binding proteins are unusually enriched in such sequences raising the question as to what function these domains serve in RNA metabolism. One such yeast protein, Nab3, is an 802 amino acid termination factor that contains an RNA recognition motif and a glutamine/proline rich domain adjacent to a region with structural similarity to a human hnRNP.

Amyloid-like assembly of the low complexity domain of yeast Nab3.

Termination of transcription of short non-coding RNAs is carried out in yeast by the Nab3-Nrd1-Sen1 complex. Nab3 and Nrd1 are hnRNP-like proteins that dimerize and bind RNA with sequence specificity. We show here that an essential region of Nab3 that is predicted to be prion-like based upon its sequence bias, formed amyloid-like filaments.

A network of interdependent molecular interactions describes a higher order Nrd1-Nab3 complex involved in yeast transcription termination.

Nab3 and Nrd1 are yeast heterogeneous nuclear ribonucleoprotein (hnRNP)-like proteins that heterodimerize and bind RNA. Genetic and biochemical evidence reveals that they are integral to the termination of transcription of short non-coding RNAs by RNA polymerase II. Here we define a Nab3 mutation (nab3Δ134) that removes an essential part of the protein's C terminus but nevertheless can rescue, in trans, the phenotype resulting from a mutation in the RNA recognition motif of Nab3.

Spontaneous intrahepatic haemorrhage: two cases of segmental arterial mediolysis.

Background: Segmental arterial mediolysis (SAM) is an under-recognized degenerative vascular disorder with variable clinical presentations. It affects medium to large calibre arteries, typically those arising from the coeliac axis, and its diagnosis is complicated by overlap with other clinical entities like fibromuscular dysplasia. Diagnosis requires histopathological examination of the affected tissue, although radiographic appearances can be suggestive of SAM.

Determinants of the core functions of local public health agencies: examining what matters in local public health practice.

Context: This study examines a model of performance measurement in public health on the basis of logic model constructs focusing upon explanatory variables (inputs) within the realm of control of the local public health agency (LPHA), and their subsequent effect on LPHA functions (outputs).

Methods: Study protocol was reviewed and approved by an institutional review board, and informed consent was obtained from all participants. The investigation included measuring the human, informational, organizational and fiscal resources of the LPHAs (inputs) to determine the effect upon LPHA performance of the assessment, policy development, and assurance functions of public health (outputs), commonly referred to as the 3 core functions of public health.

Surgical implications of a left-sided gallbladder.

Background: A left-sided gallbladder in a normally positioned liver is considered to be a very uncommon anomaly. Laparoscopic cholecystectomy can be performed safely, but bile duct injury is not unusual. It is associated with anomalous intrahepatic portal and biliary systems which impacts any form of partial hepatectomy.

Yeast Nab3 protein contains a self-assembly domain found in human heterogeneous nuclear ribonucleoprotein-C (hnRNP-C) that is necessary for transcription termination.

Nab3 is an RNA-binding protein whose function is important for terminating transcription by RNA polymerase II. It co-assembles with Nrd1, and the resulting heterodimer of these heterogeneous nuclear ribonucleoprotein-C (hnRNP)-like proteins interacts with the nascent transcript and RNA polymerase II. Previous genetic analysis showed that a short carboxyl-terminal region of Nab3 is functionally important for termination and is located far from the Nab3 RNA recognition domain in the primary sequence.

Surgical management in patients with pancreatic cancer: a Queensland perspective.

Background: Little has been published regarding presenting symptoms, investigations and outcomes for patients with pancreatic cancer in Australia. Data from a series of patients undergoing attempted resection in Queensland, Australia, are presented with the aim of assisting development of consistent strategies in disease management.

Methods: We reviewed the medical records of 121 patients who underwent attempted surgical resection and who took part in a case-control study between 2007 and 2009.
