Until recently, studies of the fate of primary production in coastal upwelling systems have focused mainly on export through sinking of particulate organic matter (POM). In week-long deck incubations conducted during the upwelling season off Oregon, a large accumulation of carbonrich (C:N ≥ 16) dissolved organic matter (DOM) occurred following nitrate depletion by diatom blooms. The response of...

The voltage-gated sodium channel Na(v)1.7 plays a crucial role in pain, and drugs that inhibit hNa(v)1.7 may have tremendous therapeutic potential. ProTx-II and huwentoxin-IV (HWTX-IV), cystine knot peptides from tarantula venoms, preferentially block hNa(v)1.7. Understanding the interactions of these toxins with sodium channels could aid the development of novel pain therapeutics. Whereas both...

Abstract We simulate the failure recovery process and study phase transition from high network activity (HNA) state to low (LNA) of coupled consisting a regular (RN) an Erdos-Rényi (ERN). Two mechanisms are considered, internal external recovery, in process. find that evolution is crucially dependent on coupling strength c between two subnetworks possibility r since RN sensitive recovery. A wea...

We report the findings in five muscle and three sural nerve biopsies, and in one postmortem plexus specimen, from six patients with hereditary neuralgic amyotrophy (HNA). We found that the sensory nerves are definitely involved in HNA despite the mainly motor symptoms, and that lesions in nerves and muscles are more widespread throughout the peripheral nervous system than clinically presumed, b...

We present a method for low loss coupling of multiple fibers to optical waveguides. Simultaneous alignment of multiple fibers is done by placing the fibers in a V-groove array. Coupling efficiency can be enhanced by placing a high numerical aperture (HNA) fiber (MFD 4 μm) between the standard telecom fiber and a horizontal tapered waveguide. The splicing loss between the standard telecom fiber ...

Heterotrophic bacteria are significant components of prokaryotic communities in marine ecosystems (AzAm & HodSoN, 1977). methods developed in last few decades for studying microorganisms, including optical, radioactive marking methods and molecular techniques, have shown that many of the methods previously used actually ignored A one-year survey of HNA and LNA heterotrophic bacteria abundance a...

Increasing efferent renal sympathetic nerve activity (ERSNA) increases afferent renal nerve activity (ARNA), which in turn decreases ERSNA via activation of the renorenal reflexes in the overall goal of maintaining low ERSNA. We now examined whether the ERSNA-induced increases in ARNA are modulated by dietary sodium and the role of endothelin (ET). The ARNA response to reflex increases in ERSNA...

OBJECTIVES This study aimed to develop a health needs assessment (HNA) tool for persons with brain disorders and to assess the unmet needs of persons with brain disorders using the developed tool. METHODS The authors used consensus methods to develop a HNA tool. Using a randomized stratified systematic sampling method adjusted for sex, age, and districts, 57 registered persons (27 severe and ...

Transfusion-related acute lung injury (TRALI) is a severe complication related with blood transfusion. TRALI has usually been associated with antibodies against leukocytes. The flow cytometric granulocyte immunofluorescence test (Flow-GIFT) has been introduced for routine use when investigating patients and healthy blood donors. Here we describe a novel tool in the automation of the Flow-GIFT t...

Hereditary neuropathy with liability to pressure palsies (HNPP; also called tomaculous neuropathy) is an autosomal-dominant disorder that produces a painless episodic, recurrent, focal demyelinating neuropathy. HNPP generally develops during adolescence, and may cause attacks of numbness, muscular weakness, and atrophy. Peroneal palsies, carpal tunnel syndrome, and other entrapment neuropathies...
