Efficient connection of multiple electrodes to the body for impedance measurement and voltage monitoring applications is of critical importance to measurement quality and practicality. Electrical impedance tomography (EIT) experiments have generally required a cumbersome procedure to attach the multiple electrodes needed in EIT. Once placed, these electrodes must then maintain ...

Micro particle image velocimetry (µPIV) is a common method to assess flow behavior in blood microvessels in vitro as well as in vivo. The use of red blood cells (RBCs) as tracer particles, as generally considered in vivo, creates a large depth of correlation (DOC), even as large as the ...

AIM: Cardiac contraction and relaxation are mediated by rapidly changing calcium concentration around the myofibrils. In comparison with endotherms, ectothermic hearts are more strongly dependent on extracellular calcium for contraction suggesting this trait might represent the primitive vertebrate mode of cardiac activation. This study tests the hypothesis that intracellular calcium ...

More than a century has passed since the first tracheoplasty was successfully performed by Eiselsberg in 1896. In that time, tracheobronchoplasty has developed with the extension of operative indications. This review focuses on who contributed to the development of this operation in Japan, and in what ways, with comparisons to ...

Obesity and related metabolic abnormalities, including a state of chronic inflammation, increase the risk of hepatocellular carcinoma (HCC). Adipose tissue constitutively expresses the proinflammatory cytokine tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6), which are important tumor promoters in inflammation-related carcinogenesis. Dysregulation of TNF-α and IL-6 is associated with the development ...

One of the major failure modes of bioprosthetic heart valves is non-calcific structural deterioration due to fatigue of the tissue leaflets. Experimental methods to characterize tissue fatigue properties are complex and time-consuming. A constitutive fatigue model that could be calibrated by isolated material tests would be ideal for investigating the ...

Mercury (Hg) adversely affects the health and behavior of exposed wildlife; however, behavioral effects remain largely unknown. Changes in avian singing behavior may affect a male's fitness because song reveals male quality and thus influences female mate choice and male territory-holding ability. Nelson's sparrows (Ammodramus nelsoni) live exclusively on salt ...

Polygalacturonases (EC 3.2.1.15) hydrolyze the α-1,4-glycosidic linkages in polygalacturonic acid chains. The interest on specific inhibitors of pectinase and the versatility of magnetic support for enzyme immobilization endorsed the preparation of an immobilized enzyme reactor (IMER). This work presents the synthesis of CoFe(2)O(4) amino-derivatives, which was employed as the support ...

The mechanisms by which algae disperse across space on coral reefs are poorly known. We investigated the ability of four common Caribbean herbivorous fish species to disperse viable algal fragments through consumption of macroalgae and subsequent defecation. Fragments of all major algal taxa (Phaeophyta, Rhodophyta, and Chlorophyta) were found in ...

Several anti-HIV aptamers adopt DNA quadruplex structures. Among these, "Hotoda's aptamer" (base sequence TGGGAG) was one of the first to be discovered. Although it has been the topic of some recent research, no detailed structural investigations have been reported. Here we report structural investigations on this aptamer and analogues with ...

Racialised language is a salient and contested aspect of contemporary sexual cultures, particularly in the online domain. This paper explores the ways in which gay men in Australia employ race-related language when using online sex/dating websites. Using inductive content analysis, descriptive categories were developed to identify recurrent patterns in the ...

Based on an effective two-orbital tight-binding model, we examine the possible superconducting states in iron-vacancy-ordered A(y)Fe(2-x)Se(2). In the presence of ordered vacancies and blocked antiferromagnetic order, it is shown that the emergent SC pairing is the nodeless next-nearest-neighbor (NNN)-pairing due to the dominant antiferromagnetic (AFM) interaction between the inter-block NNN ...

First described in the late 1960s, N-alkylsulfonylimines are heterocumulenes that participate in reactions with a range of 1,3-dipoles to afford interesting 3-, 4-, 5-, and 6-membered heterocycles. The distribution of adducts obtained suggests that multistage, stepwise mechanistic pathways rather than a concerted process are in operation.

Tumor necrosis factor (TNF)-α and interleukin (IL)-10 are cytokines involved in the balance between cell-mediated and humoral immunity. We investigated whether serum TNF-α and IL-10 levels have any impact on clinical outcome of patients with chronic lymphocytic leukemia (CLL). TNF-α and IL-10 levels were determined in the serum of 160 ...

BPKS from Botrytis cinerea is a novel type III polyketide synthase that accepts C(4)-C(18) aliphatic acyl-CoAs and benzoyl-CoA as the starters to form pyrones, resorcylic acids and resorcinols through sequential condensation with malonyl-CoA. The catalytic efficiency (k(cat)/K(m)) of BPKS was 2.8 × 10(5) s(-1) M(-1) for palmitoyl-CoA, the highest ever ...

ARABIDILLO proteins regulate multicellular root development in Arabidopsis thaliana. Conserved ARABIDILLO homologues are present throughout land plants, even in early-evolving plants that do not possess complex root architecture, suggesting that ARABIDILLO genes have additional functions. Here, we have cloned and characterised ARABIDILLO gene homologues from two early-evolving land plants, the ...

To recognize that a picture is a representation of a real-life object is a cognitively demanding task. It requires an organism to mentally represent the concrete object (the picture) and abstract its relation to the item that it represents. This form of representational insight has been shown in a small ...

Marine methane bubbles are absorbed, steadily stored and continuously transported based on the employment of superhydrophobic sponges. antiwetting sponges are water-repellent in the atmosphere and absorb gas bubbles under water. Their capacity to store methane bubbles increases with enhanced submerged depth. Significantly, trapped methane bubbles can be continuously transported driven ...

SCOPE: Until now, the question of how the ingested doses of chlorogenic acids (CGA) from coffee influence their absorption and metabolism remains unresolved. To assess absorption in the small intestine, we performed a dose-response study with a randomized, double-blinded, crossover design with ileostomist subjects. METHODS AND RESULTS: After a polyphenol-free ...

In healthy humans, the incretin glucagon-like peptide 1 (GLP-1) is secreted after eating and lowers glucose concentrations by augmenting insulin secretion and suppressing glucagon release. Additional effects of GLP-1 include retardation of gastric emptying, suppression of appetite and, potentially, inhibition of β-cell apoptosis. Native GLP-1 is degraded within ∼2-3 min ...

Reasons for performing study: Noncontrast magnetic resonance angiography (MRA) is widely used in human and small animal medicine. However, this technique has not yet been described in the horse, and compared to other angiographic techniques MRA could be more cost efficient and potentially safer. Objectives: The aim of this study ...

It has been considered since the first discovery of a high-T(c) cuprate that an antiferromagnetic (AF) state and a superconducting (SC) state are separated in it. However, it is very intriguing that the coexistence of the AF and SC states has recently been observed in HgBa(2)Ca(4)Cu(5)O(12+) (Hg-1245). Moreover, it is ...
