INTRODUCTION: Transplant surgeons conventionally select against livers displaying high degrees (>30%) of macrosteatosis (MaS), out of concern for primary non-function or severe graft dysfunction. As such, there is relatively limited experience with such livers, and the natural history remains incompletely characterized. We present our experience of transplanted livers with high degrees of MaS and microsteatosis (MiS), with a focus on the histopathologic and clinical outcomes. METHODS: 29 cases were identified with liver biopsies available from both the donor and the corresponding liver transplant recipient...

Heparin is one of the oldest drugs, which nevertheless remains in widespread clinical use as an inhibitor of blood coagulation. The history of its identification a century ago unfolded amid one of the most fascinating scientific controversies turning around the distribution of credit for its discovery. The composition, purification and structure-function relationship of this naturally occurring glycosaminoglycan regarding its classical role as anticoagulant will be dealt with before proceeding to discuss its therapeutic potential in, among other, inflammatory and infectious disease, cancer treatment, cystic fibrosis and Alzheimer's disease...

BACKGROUND: Mutations in the nuclear-encoded mitochondrial DNA polymerase gamma (POLG) can result in a wide spectrum of neurological deficits. A common presentation is progressive ataxia (POLG-A) which includes impaired speech and swallowing. The nature, severity and impact of these deficits in POLG-A is not known. A comprehensive quantitative and qualitative characterization of dysarthria and dysphagia in this recurrent ataxia disorder will assist in diagnostics, provide insights into the underlying pathology, and establish the foundation for future therapy trials...

Background: Leprosy is a complex infectious and neurological disease caused by Mycobacterium leprae. Nerve damage is related to immunological hypersensitivity responses known as leprosy reactions (LRs). Diagnostic tools to predict LRs are not available. We hypothesized that natural octyl disaccharide-leprosy IDRI diagnostic (NDO-LID) would be helpful as an indicator of LRs and neuritis. Methods: To assess the utility of NDO-LID in indicating reactions, ELISA were used to detect specific antibodies in serum samples from 80 Colombian leprosy patients (40 with and 40 without history of LRs)...

Animals are exposed in nature to a variety of stressors. While stress is generally harmful, mild stress can also be beneficial and contribute to reproduction and survival. We studied the effect of five cold shock events vs. a single cold shock and a control group, representing three levels of stress (harsh, mild, and no stress), on behavioral, physiological, and life-history traits of the red flour beetle (Tribolium castaneum, Herbst 1797). Beetles exposed to harsh cold stress were less active than a control group: they moved less and failed more frequently to detect a food patch...

The influence of hepatitis B virus (HBV) genotypes in the natural history of the disease and its response to antiviral treatment have been addressed in many studies. In Brazil, studies on HBV genotype circulation have been restricted to specific population groups and states. Here, we have conducted a nationwide multicentre study with an unprecedented sample size representing all Brazilian regions in an effort to better understand the viral variants of HBV circulating among chronic carriers. Seven HBV genotypes were found circulating in Brazil...

The term 'nurse' (hushi-'caring scholar') did not enter the Chinese language until the early 20th century. Modern nursing-a fundamentally Western notion popularized by Nightingale and introduced to China in 1884-profoundly changed the way care of the sick was practiced. For 65 years, until 1949, nursing developed in China as a transnational project, with Western and Chinese influences shaping the profession of nursing in ways that linger today. Co-authored by Chinese, Canadian, and American nurses, this paper examines the early stages of nursing in one province of China as an exemplar of the transnational nature of nursing development...

Cystic hygroma (CH) is a benign infiltrative malformation of the lymphatic channels. We report a case of a 28-year-old Indian female who presented with rapidly enlarging right sided neck swelling over the posterior triangle since 5 days. Complete resection of CH is sometimes not amenable because of its infiltrative nature and involvement of surrounding vital structures. However, in our patient successful complete surgical resection was undertaken. The MRI findings of our patient were consistent with brachial cleft cyst; this posed a challenge in the diagnosis of CH...

BACKGROUND: A substantial amount of work has examined language abilities in young children with specific language impairment (SLI); however, our understanding of the developmental trajectory of language impairment is limited. Along with studying the behavioral changes that occur across development, it is important to examine the neural indices of language processing for children with different language trajectories. The current study sought to examine behavioral and neural bases of language processing in adolescents showing three different trajectories: those with normal language development (NL), those exhibiting persistent SLI (SLI-Persistent), and those with a history of SLI who appear to have recovered (SLI-Recovered)...

The generation and maintenance of functional variation in the pathogen defense system of plants is central to the constant evolutionary battle between hosts and parasites. If a species is susceptible to a given pathogen, hybridisation and subsequent introgression of a resistance allele from a related species can potentially be an important source of new immunity and is therefore expected to be selected for in a process referred to as adaptive introgression. Here we survey sequence variation in ten resistance (R) genes and compare with 37 reference genes in natural populations of the two closely related and interfertile species Arabidopsis lyrata and A...

Flaviviruses present substantial differences in their host range and transmissibility. We studied the evolution of base composition, dinucleotide biases, codon usage and amino acid frequencies in the genus Flavivirus within a phylogenetic framework by principal components analysis. There is a mutual interplay between the evolutionary history of flaviviruses and their respective vectors and/or hosts. Hosts associated to distinct phylogenetic groups may be driving flaviviruses at different pace and through various sequence landscapes, as can be seen for viruses associated with Aedes or Culex spp...

Advances in understanding diabetes mellitus (DM) through basic and clinical research have helped clarify and reunify a disease state fragmented into numerous etiologies and subtypes. It is now understood that a common pathophysiology drives the diabetic state throughout its natural history and across its varied clinical presentations, a pathophysiology involving metabolic insults, oxidative damage, and vicious cycles that aggravate and intensify organ dysfunction and damage. This new understanding of the disease requires that we revisit existing diagnostics and treatment approaches, which were built upon outmoded assumptions...

In the eighteenth century, the historiography of astronomy was part of a wider discussion concerning the history of the human spirit. The concept of the human spirit was very popular among Enlightenment authors because it gave the history of human knowledge continuity, unity and meaning. Using this concept, scientists and historians of science such as Montucla, Lalande, Bailly and Laplace could present the history of astronomy in terms of a progress towards contemporary science that was slow and could be interrupted at times, but was still constant, regular, and necessary...

Non-alcoholic fatty liver disease (NAFLD) is one of the most common complications of obesity. Several studies have shown that genetic predisposition probably plays an important role in its pathogenesis. In fact, in the last few years a large number of genetic studies have provided compelling evidence that some gene variants, especially those in genes encoding proteins regulating lipid metabolism, are associated with intra-hepatic fat accumulation. Here we provide a comprehensive review of the gene variants that have affected the natural history of the disease...

In this study, we report the outcome for spontaneous recovery of elbow flexion in obstetric brachial plexus injury managed without nerve reconstruction. Excluding those with transient paralysis, our records revealed 152 children with obstetric brachial plexus injury born before our unit routinely offered brachial plexus reconstruction. Five had had nerve repairs. Of the remainder, only one patient had insufficient flexion to reach their mouth. Elbow flexion started to recover clinically at a mean age of 4 months for Narakas Group 1, 6 months for Group 2, 8 months for Group 3 and 12 months for Group 4...

Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease which is associated with inflammatory bowel disease (IBD) in most cases. As there is currently no medical therapy which alters the natural history of PSC, liver transplantation may be required. Areas covered: We searched for articles in PubMed and critically reviewed current literature on the interrelationship between PSC and IBD with a specific focus on considerations for patients in the liver transplant setting. Expert commentary: PSC is an uncommon disease which limits available studies to be either retrospective or contain relatively small numbers of patients...
