In the western Amazon basin, recent intensification of river level cycles has increased flooding during the wet seasons and decreased precipitation during the dry season. Greater than normal floods occurred in 2009 and in all years from 2011-2015 during high water seasons, and a drought occurred during the 2010 low water season. During these years, we surveyed populations of terrestrial, arboreal and aquatic wildlife in a seasonally flooded Amazonian forest to study the consequences of intensification of climatic fluctuations to wildlife populations and in turn resource use by traditional people...

BACKGROUND AND OBJECTIVE: Ménière's disease (MD) is a disorder of the inner ear typically showing recurrent acute episodes of vertigo, hearing loss, and tinnitus. Epidemiologic studies on MD are scarce. We assessed the incidence rates (IRs) of MD and describe the characteristics of MD cases, comparing them to control patients without recorded evidence of MD. STUDY DESIGN: We conducted a retrospective population-based follow-up study and a nested case-control analysis using data from the UK-based Clinical Practice Research Datalink...

Unexplained iron-deficiency anemia is an important marker for colorectal cancer (CRC). Our objectives were as follows: (a) to assess whether the association between anemia and CRC can be detected on the 'Clinical Practice Research Datalink', (b) to evaluate the timing between laboratory changes and CRC detection, and (c) to analyze its association with survival. We conducted a case-control study on patients with an incident CRC diagnosis during 2008-2012 and a 1 : 1-matched control group. We compared anemia markers serum ferritin (SF), hemoglobin (Hb), mean corpuscular volume (MCV), and red blood cell count between cases and controls using conditional logistic regression...

KEY POINTS: Changes in gene expression that occur within hours of exposure to hypoxia in in vivo skeletal muscles remain unexplored. Two hours of hypoxia caused significant down-regulation of extracellular matrix genes followed by a shift at 6 h to altered expression of genes associated with the nuclear lumen while respiratory and blood gases were stabilized. Enrichment analysis of mRNAs classified by stability rates suggests an attenuation of post-transcriptional regulation within hours of hypoxic exposure, where PI3K-Akt signalling was suggested to have a nodal role by pathway analysis...

GPER is a membrane-associated estrogen receptor of the family of G-protein coupled receptors. For breast cancer, the contribution of GPER to promoting the proliferation and migration of both carcinoma cells and cancer-associated fibroblasts (CAFs) in response to estrogen and other agonists has extensively been investigated. Intriguingly, GPER was previously found to be localized to the nucleus in one isolate of breast CAFs. Moreover, this nuclear GPER was shown to bind regulatory sequences of cancer-relevant target genes and to induce their expression...

The process of gentamicin-induced hair cell damage includes the activation of oxidative stress processes. Sestrins, as stress-responsive proteins, protect cells against oxidative stress. Sestrins, particularly Sestrin-2, suppress excessive reactive oxygen species (ROS) accumulation and inhibit mammalian target of rapamycin complex 1 (mTORC1). Thus, we addressed the role of Sestrin-2 in the regulation of sensory hair cell survival after gentamicin exposure. Here, we show that Sestrins were expressed in the inner ear tissues, and Sestrin-2 immunolocalized in sensory hair cells and spiral ganglion (SG)...

BACKGROUND: Early identification of people at risk for a contralateral hip fracture would be desirable to favorably influence patients' prognosis. A recent systematic review failed to depict stringent patterns of risk parameters to be used for decision-making in clinical practice. OBJECTIVE: To perform a consensus study using the Delphi method to reach an expert consensus on predictive parameters for the occurrence of a fall and a contralateral hip fracture 1 and 3 years after hip fracture...

Encodable lanthanide binding tags (LBTs) have become an attractive tool in modern structural biology as they can be expressed as fusion proteins of targets of choice. Previously, we have demonstrated the feasibility of inserting encodable LBTs into loop positions of interleukin-1β (Barthelmes et al. in J Am Chem Soc 133:808-819, 2011). Here, we investigate the differences in fast dynamics of selected loop-LBT interleukin-1β constructs by measuring (15)N nuclear spin relaxation experiments. We show that the loop-LBT does not significantly alter the dynamic motions of the host protein in the sub-τc-timescale and that the loop-LBT adopts a rigid conformation with significantly reduced dynamics compared to the terminally attached encodable LBT leading to increased paramagnetic alignment strength...

Traumatic amputation of the thumb at the proximal phalanx or the metacarpophalangeal joint can be treated by distraction lengthening depending on the location of the amputation, the patient's age, occupation and functional demands. We report the results of proximal phalanx lengthening in 5 patients using a semicircular ring-type external fixator device. This prototype was developed at our clinic in collaboration with a specialised small company (Rotomed AG, Allmenstrasse 4, CH-4512 Bellach, www.rotomed.ch) based on the principles of Ilizarov's external fixator...

Mutations in the Parkin gene (PARK2) have been linked to a recessive form of Parkinson's disease (PD) characterized by the loss of dopaminergic neurons in the substantia nigra. Deficiencies of mitochondrial respiratory chain complex I activity have been observed in the substantia nigra of PD patients, and loss of Parkin results in the reduction of complex I activity shown in various cell and animal models. Using co-immunoprecipitation and proximity ligation assays on endogenous proteins, we demonstrate that Parkin interacts with mitochondrial Stomatin-like protein 2 (SLP-2), which also binds the mitochondrial lipid cardiolipin and functions in the assembly of respiratory chain proteins...

Drosophila melanogaster is a good model species for the study of heart function. However, most previous work on D. melanogaster heart function has focused on the effects of large-effect genetic variants. We compare heart function among 18 D. melanogaster populations that have been selected for altered development time, aging, or stress resistance. We find that populations with faster development and faster aging have increased heart dysfunction, measured as percentage heart failure after electrical pacing. Experimental evolution of different triglyceride levels, by contrast, has little effect on heart function...

Premenstrual disorders (PMD) can affect women throughout their entire reproductive years. In 2016, an interdisciplinary expert meeting of general gynecologists, gynecological endocrinologists, psychiatrists and psychologists from Switzerland was held to provide an interdisciplinary algorithm on PMD management taking reproductive stages into account. The Swiss PMD algorithm differentiates between primary and secondary PMD care providers incorporating different levels of diagnostic and treatment. Treatment options include cognitive behavioral therapy, alternative therapy, antidepressants, ovulation suppression and diuretics...

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but life-threatening mucocutaneous diseases. SJS/TEN mostly manifest as a reaction to new drug use, but little is known about their incidence and epidemiology. We conducted a large observational study on the epidemiology of SJS/TEN using data from the UK-based Clinical Practice Research Datalink. Among 551 validated SJS/TEN patients, we calculated an incidence rate of 5.76 SJS/TEN cases per million person-years between 1995 and 2013, which was consistent throughout the study period and was highest in patients aged 1-10 years and 80 years or older...

Patient-derived xenograft (PDX) models for cancer research have recently attracted considerable attention in both the academy and industry (Hidalgo et al., 2014; Wilding and Bodmer, 2014). PDX models have been developed from different tumor types including lung cancer to improve the drug development process. These models are used for pre-clinical drug evaluation and can be used for the predictive results of clinical outcomes because they conserve original tumor characteristics such as heterogeneity, complexity and molecular diversity (Kopetz et al...
