BACKGROUND: Previous studies have reported the factors contributing to chronic ankle instability, which could lead to more effective treatments. However, factors such as the reflex response and ankle muscle strength have not been taken into account in previous investigations. METHODS: Fifty recreational athletes with chronic ankle instability and 55 healthy controls were recruited. Peroneal reaction time in response to sudden inversion, isokinetic evertor muscle strength and dynamic balance with the Star Excursion Balance Test and the Biodex Stability System were measured...

INTRODUCTION: We report a rare case of complete spontaneous necrosis of a hepatocellular carcinoma (HCC) accompanied by portal vein tumor thrombosis (PVTT), as confirmed by resection. CASE PRESENTATION: A 64-year-old man was referred to our hospital for suspected HCC. Contrast-enhanced computed tomography (CECT) findings before admission revealed a 53-mm tumor in the posterior segment of the liver and were suspicious for PVTT in the right posterior PV. Both alpha-fetoprotein (AFP) and proteins induced by vitamin K absence or antagonist-II (PIVKA-II) were elevated at 17,562 ng/mL and 153 mAU/mL, respectively...

INTRODUCTION: CXCR4 specific [18 F]-labeled positron emission tomography (PET) imaging agents are needed which would enable general distribution of the radiotracer for clinical investigation. We sought to synthesize, radiolabel and evaluate [18 F]RPS-544, a novel non-peptide CXCR4 antagonist as a CXCR4 specific probe. We compared [18 F]RPS-544 with the previously published [18 F]-3 ([18 F]RPS-510 in this paper) in a bi-lateral tumor model of differential CXCR4 expression for its ability to selectively target CXCR4 expression...

BACKGROUND AND AIMS: Higher cardiorespiratory fitness is associated with lower pulse wave velocity and arterial stiffness in normal weight individuals, and this has not been examined in obese individuals. It is unclear whether an altered body composition acts as a modifier of the association between cardiorespiratory fitness and arterial stiffness. We examined the association between peak oxygen uptake and brachial-ankle pulse wave velocity and analysed whether body composition attenuates this association in obese middle-aged individuals...

The existence of sex differences in digit-length ratio (especially between the second and fourth digits, 2D:4D) is well established for humans from fetal life onwards, and has been linked with later performance. In rodents, the ratio is affected prenatally by exposure to androgens and estrogens, with some research suggesting an influence from sex of the neighbouring intrauterine fetus. However, the ubiquity and ontogenetic development of sexual dimorphism in digit ratios is not well established among wild amniotes...

There are clear differences in the normal radiographic appearance of the abdominal organs between a left lateral vs. a right lateral view. While a few veterinary academic institutions have transitioned to a three-view abdominal radiographic study protocol, obtaining only two views of the canine abdomen remains the current standard in veterinary medicine. In this combined retrospective and prospective, case-controlled study, 48 canine patients presenting with signs of acute abdomen were recruited. Four board-certified veterinary radiologists and four general practice veterinarians with greater than 3 years of experience in small animal practice were asked to determine if 10 predetermined findings were present within the set of images and if surgery was recommended based on those findings...

In a recent BioEssays paper [W. F. Martin, BioEssays 2017, 39, 1700115], William Martin sharply criticizes evolutionary interpretations that involve lateral gene transfer (LGT) into eukaryotic genomes. Most published examples of LGTs in eukaryotes, he suggests, are in fact contaminants, ancestral genes that have been lost from other extant lineages, or the result of artefactual phylogenetic inferences. Martin argues that, except for transfers that occurred from endosymbiotic organelles, eukaryote LGT is insignificant...

INTRODUCTION: Infection-triggered disease onset, chronic immune activation and autonomic dysregulation in Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) point to an autoimmune disease directed against neurotransmitter receptors. We had observed elevated autoantibodies against ß2 adrenergic receptors, and muscarinic 3 and 4 acetylcholine receptors in a subset of patients. Immunoadsorption (IA) was shown to be effective in removing autoantibodies and improve outcome in various autoimmune diseases...

Distraction osteogenesis is an effective method for generating large amounts of bone in situ for treating pathologies such as large bone defects or skeletal malformations, for instance leg-length discrepancies. While an optimized distraction procedure might have the potential to reduce the rate of complications significantly, our knowledge of the underlying mechanobiological processes is still insufficient for systematic optimization of treatment parameters such as distraction rate or fixation stiffness. We present a novel numerical model of lateral distraction osteogenesis, based on a mechanically well-controlled in vivo experiment...

Body size governs predator-prey interactions, which in turn structure populations, communities, and food webs. Understanding predator-prey size relationships is valuable from a theoretical perspective, in basic research, and for management applications. However, predator-prey size data are limited and costly to acquire. We quantified predator-prey total length and mass relationships for several freshwater piscivorous taxa: crappie (Pomoxis spp.), largemouth bass (Micropterus salmoides), muskellunge (Esox masquinongy), northern pike (Esox lucius), rock bass (Ambloplites rupestris), smallmouth bass (Micropterus dolomieu), and walleye (Sander vitreus)...

The last confirmed wild poliovirus (WPV) case in Democratic Republic of the Congo (DRC) had paralysis onset in December 2011 (1). DRC has had cases of vaccine-derived polioviruses (VDPVs) documented since 2004 (Table 1) (1-6). After an outbreak of 30 circulating VDPV type 2 (cVDPV2) cases during 2011-2012, only five VDPV2 cases were reported during 2013-2016 (Table 1) (1-6). VDPVs can emerge from oral poliovirus vaccine (OPV types 1, 2, or 3; Sabin) polioviruses that have genetically mutated resulting in reversion to neurovirulence...

Humans rely on topographical memory to encode information about spatial aspects of environments. However, even though people adopt different strategies when learning new maps, little is known about the impact of those strategies on topographical memory, and their neural correlates. To examine that issue, we presented participants with 40 unfamiliar maps, each of which displayed one major route and three landmarks. Half were instructed to memorize the maps by focusing on the route, whereas the other half memorized the maps by focusing on the landmarks...

The aim of this study was to analyze eyebrow shapes in portraits of Chinese empresses of Ming and Qing dynasties.The frontal portraits of 20 Ming empresses and 24 of Qing in which the eye and eyebrows were identifiable were measured and analyzed. The arch shape did not differ significantly (P > 0.05) between Ming and Qing. The head-up type (66.6%) was significantly more common (P < 0.001), than tail-up (13.6%), horizontal (13.6%), and arched (6.8%). The brow arches of Ming and Qing empresses were classified as 5 arch types: L (Lamas), A (Anastasia), H (Hwang), M (Empress Ma), and D (Empress Du)...

BACKGROUND: Although several data suggest that serum uric acid (SUA) predicts future development of metabolic abnormalities, the evidence is not conclusive in Mediterranean populations. METHODS: A total of 3200 individuals were randomly selected from the residents of Monza (North Italy) to be representative of its general population for sex and age (25-74 years). The participation rate was 64%. At baseline and 10 years later, we measured waist circumference, office blood pressure, fasting blood glucose, serum triglycerides, serum HDL cholesterol and SUA...

Mesonephric adenocarcinoma (MNA) is believed to arise from benign mesonephric remnants or hyperplasia located in the lateral walls of the uterine cervix. They are uncommon in other sites of the gynecologic tract, and exceptionally rare in the uterine corpus. So far, only 30 cases of uterine MNA have been reported in the literature, as a result, the etiology, clinical behavior, choice of treatment, and histogenesis of uterine MNA are still unclear. In this study, we report 2 cases of MNA of uterine corpus. One case involved the inner half of myometrium with endometrial involvement; the second case involved the outer half of myometrium without endometrial involvement...

Injection site reactions (ISRs; redness, swelling and pain) commonly occur within 1-2 days after vaccination. After administration of toxoid vaccines including diphtheria toxoid, a later onset of ISRs has also been observed. As the serotype capsular polysaccharides in the 13-valent pneumococcal conjugate vaccine (PCV13) are conjugated to cross-reactive material 197 (CRM197 ), a nontoxic variant of diphtheria toxin, the onset of ISRs over 14 days was explored in 8 adult studies with 19 cohorts. Subjects received PCV13 with aluminum phosphate (AlPO4 , n = 5667) or without AlPO4 (n = 304); 109 subjects received 23-valent pneumococcal polysaccharide vaccine (PPSV23)...
