In China, the health impact of cold weather has received little attention, which limits our understanding of the health impacts of climate change. We collected daily mortality and meteorological data in 66 communities across China from 2006 to 2011. Within each community, we estimated the effect of cold spell exposure on mortality using a Distributed Lag Nonlinear Model (DLNM). We also examined the modification effect of cold spell characteristics (intensity, duration, and timing) and individual-specific factors (causes of death, age, gender and education)...

Macrophages play a critical role in obesity-associated chronic inflammation and disorders. However, the molecular mechanisms underlying the response of macrophages to elevated fatty acids (FAs) and their contribution to metabolic inflammation in obesity remain to be fully elucidated. In this article, we report a new mechanism by which dietary FAs, in particular, saturated FAs (sFAs), are able to directly trigger macrophage cell death. We demonstrated that excess sFAs, but not unsaturated FAs, induced the production of cytotoxic ceramides (Cers) in macrophage cell lines...

Acid Ceramidase Deficiency (Farber disease, FD) is an ultra-rare Lysosomal Storage Disorder that is poorly understood and often misdiagnosed as Juvenile Idiopathic Arthritis (JIA). Hallmarks of FD are accumulation of ceramides, widespread macrophage infiltration, splenomegaly, and lymphocytosis. The cytokines involved in this abnormal hematopoietic state are unknown. There are dozens of ceramide species and derivatives, but the specific ones that accumulate in FD have not been investigated. We used a multiplex assay to analyze cytokines and mass spectrometry to analyze ceramides in plasma from patients and mice with FD, controls, Farber patients treated by hematopoietic stem cell transplantation (HSCT), JIA patients, and patients with Gaucher disease...

Lipids such as ceramides (Cer) and phosphatidylcholines (PC) have been found altered in the plasma of Alzheimer's disease (AD) patients in a number of discovery studies. For this reason, the levels of 6 ceramides and 3 PCs, with different fatty acid length and saturation levels, were measured in the plasma from 412 participants (AD n = 205, Control n = 207) using mass spectrometry coupled with ultra-performance liquid chromatography. After this, associations with AD status, brain atrophy, and age-related effects were studied...

Recent completion of a thirty two channel main-ion (deuterium) charge exchange recombination spectroscopy (CER) diagnostic on the DIII-D tokamak [J. L. Luxon, Nucl. Fusion 42, 614 (2002)] enables detailed comparisons between impurity and main-ion temperature, density, and toroidal rotation. In a H-mode DIII-D discharge, these new measurement capabilities are used to provide the deuterium density profile, demonstrate the importance of profile alignment between Thomson scattering and CER diagnostics, and aid in determining the electron temperature at the separatrix...

Medullary carcinoma of the thyroid (MTC) commonly spreads through the lymphatics to distant sites such as lung, liver and bone. Spread to the breast is rare. We report a case of metastatic MTC which progressed to develop nodal metastases to cer-vical and mediastinal regions, visceral metastases to the liver, lung and ultimately to bilateral breasts. Clinically it is important to distinguish metastatic breast lesions from primary breast cancer as each is managed differently. Both cytological and radio-logical investigations were done followed by excision biopsy...

Yield of protein per translated mRNA may vary by four orders of magnitude. Many studies analyzed the influence of mRNA features on the translation yield. However, a detailed understanding of how mRNA sequence determines its propensity to be translated is still missing. Here, we constructed a set of reporter plasmid libraries encoding CER fluorescent protein preceded by randomized 5' untranslated regions (5'-UTR) and Red fluorescent protein (RFP) used as an internal control. Each library was transformed into Escherchia coli cells, separated by efficiency of CER mRNA translation by a cell sorter and subjected to next generation sequencing...

Patients with multiple sclerosis (MS) have an increased systemic vascular resistance (SVR) response during the metaboreflex. It has been hypothesized that this is the consequence of a sedentary lifestyle secondary to MS. The purpose of this study was to discover whether a 6-month training program could reverse this hemodynamic dysregulation. Patients were randomly assigned to one of the following two groups: the intervention group (MSIT, n = 11), who followed an adapted training program; and the control group (MSCTL, n = 10), who continued with their sedentary lifestyle...

Skeletal muscle is the main tissue responsible for insulin-stimulated glucose uptake. Consumption of a high-fat diet rich in saturated fats (HFD) and obesity are associated with accumulation of intramuscular lipids that leads to several disorders, e.g. insulin resistance (IRes) and type 2 diabetes (T2D). The mechanism underlying the induction of IRes is still unknown. It was speculated that accumulation of intramuscular triacylglycerols (TAG) is linked to induction of IRes. Now, research focuses on bioactive lipids: long-chain acyl-CoA (LCACoA), diacylglycerols (DAG) and ceramides (Cer)...

Although colorectal cancer (CRC) is largely preventable through identification of pre-cancerous polyps through various screening modalities, morbidity and mortality rates remain a challenge, especially in African-American, Latino, low-income and uninsured/underinsured patients. Barriers to screening include cost, access to health care facilities, lack of recommendation to screen, and psychosocial factors such as embarrassment, fear of the test, anxiety about testing preparation and fear of a cancer diagnosis...

Systemic loss of neutral sphingomyelinase (SMPD3) in mice leads to a novel form of systemic, juvenile hypoplasia (dwarfism). SMPD3 deficiency in mainly two growth regulating cell types contributes to the phenotype, in chondrocytes of skeletal growth zones to skeletal malformation and chondrodysplasia, and in hypothalamic neurosecretory neurons to systemic hypothalamus-pituitary-somatotropic hypoplasia. The unbiased smpd3-/- mouse mutant and derived smpd3-/- primary chondrocytes were instrumental in defining the enigmatic role underlying the systemic and cell autonomous role of SMPD3 in the Golgi compartment...

Ten commercial available multi-enzymatic systems have been explored for the efficient recovery of patatin and protease inhibitors from potato pulp. Their enzyme activity profile was characterized, where corresponding enzyme activity profile led to similar protein recovery yield. Of those assessed, Depol 670L (DEP) and Ceremix 2XL (CER) were efficient for the recovery of protein extract enriched with patatin (up to 60.0%) and protease inhibitors (up to 72.0%), respectively. The efficiency of DEP was significantly dependent on the interactive effect of enzymatic units and incubation time (p-value <0...

AIMS: Weight loss improves glycaemic control in type 2 diabetes mellitus (T2DM). However, as achieving and maintaining weight loss is difficult, alternative strategies are needed. Our primary aim was to investigate the effects of intermittent energy restriction (IER) compared to continuous energy restriction (CER) on glycated haemoglobin A1c (HbA1c). Secondary aims were to assess effects on weight loss, body composition, medication changes and subjective measures of appetite. Using a 2-day IER method, we expected equal improvements to HbA1c and weight in both groups...

The ampicillin resistance plasmid pCERC7, carrying transposon Tn2 with an IS4 insertion, was detected in the draft genome of a commensal Escherichia coli isolate. The genome data also revealed that this isolate belongs to ST131, clade B. pCERC7 is 9712bp comprised of a 3319bp backbone, Tn2::IS4 (6388bp) and 5bp of target site duplication, and was present at a copy number of 40. pCERC7 is related to several plasmids composed of only the backbone, or the backbone with the Tn2 insertion in the same position. These plasmids have been found previously in Escherichia coli or Salmonella enterica recovered in several different countries from as early as the 1970s...
