AIMS: Emergency medicine is a 'high risk' specialty. Some diseases develop suddenly and progress rapidly, and sudden unexpected deaths in the emergency department (ED) may cause medical disputes. We aimed to assess discrepancies between antemortem clinical diagnoses and postmortem autopsy findings concerning emergency medicine dispute cases and to figure out the most common major missed diagnoses. METHODS: Clinical files and autopsy reports were retrospectively analysed and interpreted...

The origin of tetrodotoxin (TTX) in amphibians has long been disputed. In this study, TTX and its putative biosynthetic intermediates or shunt compounds (4,9-anhydro-10-hemiketal-5-deoxyTTX and Cep-242) were dietary administered to the captive-reared, non-toxic Japanese fire-bellied newt, Cynops pyrrhogaster. After 4 weeks, the ingested compounds were detected mainly in the newt body using liquid chromatography-mass spectrometry (LC-MS), while these compounds were not converted into other TTX analogues in newts...

The sll1981 protein from cyanobacterium Synechocystis sp. PCC6803 had been reported to exhibit acetolactate synthase (ALS) and L-myo-inositol-1-phosphate synthase (MIPS) activities previously. Based on amino acids sequences alignment, sll1981 protein was postulated to function as α-ketoglutarate decarboxylase (α-KGD), which played important role in completing cyanobacterial tricarboxylic acid (TCA) cycle. However the detailed enzymatic kinetics of sll1981 as ALS, MIPS and α-KGD were not determined yet. In this study, the recombinant sll1981 protein was purified from supernatant of E...

REVIEW
Friedemann Pulvermüller
Neurocognitive and neurolinguistics theories make explicit statements relating specialized cognitive and linguistic processes to specific brain loci. These linking hypotheses are in need of neurobiological explanation. Recent mathematical models of human language mechanisms constrained by fundamental neuroscience principles and established knowledge about comparative neuroanatomy offer explanations for where, when and how language is processed in the human brain. In these models, network structure and connectivity along with action- and perception-induced correlation of neuronal activity co-determine neurocognitive mechanisms...

N Rehan, K Qayyum
BACKGROUND: Although the incidents of customary marriages are frequently reported in Pakistani press, yet no large scale community-based study has ever been conducted to gauge the magnitude of such marriages. The present study is the first-ever community based study on this topic. METHODS: 4,385 ever-married women, aged 18-83 years, from six rural districts, were interviewed to enquire about the types of their marriages. The data was collected through interviews conducted by trained female interviewers and analysed through SPSS-20...

This article uses Marc Lewis' work as a springboard to discuss the socio-political context of the brain disease model of addiction (BDMA). The claim that promotion of the BDMA is the only way the general public can be persuaded to withhold blame and punishment from addicts is critically examined. After a discussion of public understandings of the disease concept of addiction, it is pointed out that it is possible to develop a scientific account of addiction which is neither a disease nor a moral model but which the public could understand...

BACKGROUND: The prognostic significance of tumor location for patients with upper urinary tract urothelial carcinoma (UUT-UC) has been disputed. Several papers have reported that ureteral cancer is associated with worse prognosis. OBJECTIVE: To investigate the prognostic significance of the presence of ureteral tumors in UUT-UC patients who underwent radical nephroureterectomy (RNU). DESIGN, SETTING, AND PARTICIPANTS: In this multicenter retrospective study, 1068 eligible patients (median follow-up: 40 mo [interquartile range: 17-77 mo]) were divided into three groups based on tumor location: renal pelvic, ureteral, and both-regional (having both renal pelvic and ureteral tumors)...

BACKGROUND: Presently, the matter of pregnancy outcomes of patients with pregnancy related AKI (PR-AKI) were disputed. Thus, we conducted a meta-analysis to evaluate the impact of PR-AKI on pregnancy outcomes. METHOD: We systematically searched MEDLINE, Embase, VIP, CNKI and Wanfang Databases for cohort or case-control studies in women with PR-AKI and those without AKI as a control group to assess the influence of PR-AKI on pregnancy outcomes and kidney outcome...

Distracted driving has long been acknowledged as one of the leading causes of death or injury in roadway crashes. The focus of past research has been mainly on the impact of different causes of distraction on driving behavior. However, only a few studies attempted to address how some driving behavior attributes could be linked to the cause of distraction. In essence, this study takes advantage of the rich SHRP 2 Naturalistic Driving Study (NDS) database to develop a model for detecting the likelihood of a driver's involvement in secondary tasks from distinctive attributes of driving behavior...

More often than not, the source of DNA traces found at a crime scene is not disputed, but the activity or timing of events that resulted in their transfer is. As a consequence, practitioners are increasingly asked to assign a value to DNA evidence given propositions about activities provided by prosecution and defense counsel. Given that the dispute concerns the nature of the activity that took place or the identity of the actor that carried out the activity, several factors will determine how to formulate the propositions...

Walnuts (Juglans of the Juglandaceae) are well-known economically important resource plants for the edible nuts, high-quality wood, and medicinal use, with a distribution from tropical to temperate zones and from Asia to Europe and Americas. There are about 21 species in Juglans. Classification of Juglans at section level is problematic, because the phylogenetic position of Juglans cinerea is disputable. Lacking morphological and DNA markers severely inhibited the development of related researches. In this study, the complete chloroplast genomes and two nuclear DNA regions (the internal transcribed spacer and ubiquitin ligase gene) of 10 representative taxa of Juglans were used for comparative genomic analyses in order to deepen the understanding on the application value of genetic information for inferring the phylogenetic relationship of the genus...

BACKGROUND: Fibromyalgia is a syndrome characterized by widespread pain and a variety of somatic symptoms. The international prevalence of fibromyalgia is 2-5%, but its current prevalence in Finland is unclear. Various adversities are linked to the onset of fibromyalgia. However, there is need for more data regarding the association between childhood physical abuse and fibromyalgia. Further, the association of childhood emotional stressors and fibromyalgia is disputed. The aim of the current study is to produce more information about that relationship using data from the Health and Social Support (HeSSup) Study...

To investigate the grammatical constraints of code-switching (CS hereafter) under the disputes of the constraint-based account versus the constraint-free account, the effects of functional category on CS have long been investigated in the existing studies. Thus, the present study, by asking 47 participants to take part in an eye-movement experiment, examined the potential effects of functional category on Chinese-English CS. We found that differential switch costs at varying code-switched conditions as well as robust switch effects that last from the early to the late stage...

The importance of extracellular traps (ETs) in innate immunity is well established, but the molecular mechanisms responsible for their formation remain unclear and in scientific dispute. ETs have been defined as extracellular DNA scaffolds associated with the granule proteins of eosinophils or neutrophils. They are capable of killing bacteria extracellularly. Based mainly on results with phosphoinositide 3-kinase (PI3K) inhibitors such as 3-methyladenine (3-MA) and wortmannin which are commonly used to inhibit autophagy, several groups have reported that autophagy is required for neutrophil extracellular trap (NET) formation...

Jacquie Baker, Kurt Kimpinski
Neurogenic orthostatic hypotension (NOH) can be present in a number of disorders, including synucleinopathies, autoimmune disorders, and various genetic disorders. All are characterized by defective norepinephrine release from sympathetic terminals upon standing, resulting in impaired vasoconstriction. NOH is defined as a drop in systolic blood pressure ≥20 mmHg or diastolic blood pressure ≥10 mmHg, or both, within 3 minutes of standing or head up-tilt at a minimum of 60°. However, approximately 50% of patients have associated supine hypertension, which greatly complicates treatment...

Hyperhidrosis affects 4.8% of the U.S. population and has been underestimated by physicians for long time despite considerable interference with quality of life. Many patients suffer from primary (idiopathic) hyperhidrosis which results from over-activity of sympathetic nerves and is restricted to specific body areas, mostly the axillae, palms, soles, or head. Secondary hyperhidrosis is caused by an underlying disease or the intake of medications and often involves large parts of the body. Numerous effective therapies with topical or systemic drugs and surgical options are available...

Valentin Amrhein, Fränzi Korner-Nievergelt, Tobias Roth
The widespread use of 'statistical significance' as a license for making a claim of a scientific finding leads to considerable distortion of the scientific process (according to the American Statistical Association). We review why degrading p-values into 'significant' and 'nonsignificant' contributes to making studies irreproducible, or to making them seem irreproducible. A major problem is that we tend to take small p-values at face value, but mistrust results with larger p-values. In either case, p-values tell little about reliability of research, because they are hardly replicable even if an alternative hypothesis is true...
