In our efforts toward producing environmentally responsible but highly stable bioelectrodes with high electroactivities, we report here a simple, inexpensive, autoclavable high sensitivity biosensor based on enzyme-polymer nanogels. Met-hemoglobin (Hb) is stabilized by wrapping it in high molecular weight poly(acrylic acid) (PAA, M(W) 450k), and the resulting nanogels abbreviated as Hb-PAA-450k...

hepatoblastoma (hb) is a rare tumor of infancy and childhood manifesting with hepatomegaly and abdominal distention. it is seen with increased frequency in association with congenital hemihypertrophy and renal anomalies. metastases to other organs, including the lungs, lymph nodes and even ovaries is well known. but cerebral metastasis of this tumor, especially in the absence of metastasis to o...

To investigate the effect of altitude exposure on running economy (RE), 22 elite distance runners [maximal O(2) consumption (Vo(2)) 72.8 +/- 4.4 ml x kg(-1) x min(-1); training volume 128 +/- 27 km/wk], who were homogenous for maximal Vo(2) and training, were assigned to one of three groups: live high (simulated altitude of 2,000-3,100 m)-train low (LHTL; natural altitude of 600 m), live modera...

This study described the bioelectrochemistry of hemoglobin (Hb) at multiwall carbon nanotubes (MWCNTs) noncovalently functionalized with biopolymers of sodium alginate (SA). The characteristics of Hb/SA-MWCNTs composite film were studied by using FT-IR spectroscopy, UV-vis spectroscopy and electrochemical methods. Hb immobilized on SA-MWCNTs composite film retained its native secondary structur...

Stulak, John M., Luis A. Juncos, John A. Haas, and J. Carlos Romero. Systemic hemodynamics and renal function in hemorrhaged dogs resuscitated with cross-linked hemoglobin. Am. J. Physiol. Regulatory Integrative Comp. Physiol. 278: R28–R33, 2000.—Cross-linked hemoglobin (XL-Hb) infused into dogs increases mean arterial pressure (MAP) but decreases blood flow to the renal (RBF), mesenteric (MBF)...

Objective of this study was to examine the effect of sodium nitroprusside (SNP), a nitric oxide (NO) donor on steroid synthesis, growth and apoptosis of buffalo granulosa cells (GCs) in vitro. Follicular fluid of antral follicles (3-5 mm diameter) was aspirated and GCs were cultured in 0 (control), 10, 10, 10, 10 M of SNP for 48 h. To evaluate whether this effect was reversible, GCs were cultur...

The paper presents the materials of field research on study regularities development moisture outlines light soils during drip irrigation vegetable crops. correlation is found between depth moistened layer and area moistening pre-irrigation threshold content active soil layer, standards flow rate drippers, which gives an opportunity to decline unproductive water consumption for filtration. It t...

www.turner-white.com M ethemoglobin, a unique form of hemoglobin (Hb) with diminished oxygen affinity, is formed and metabolized roughly at equivalent rates under normal physiologic conditions. However, when methemoglobin generation supersedes compensatory physiologic reductive capacity, methemoglobinemia may result. Potential etiologies of methemoglobinemia include a variety of heritable metab...

Haemoglobin (Hb) abnormalities in chronic obstructive pulmonary disease (COPD) are not well characterised. The present authors investigated the prevalence and association of abnormal Hb with clinical outcomes. Analysis of a prospective cohort of stable COPD outpatients (n = 683) in a USA Veterans Administration pulmonary clinic was undertaken. Patients were classified as anaemic (Hb <13 g.dL(-1...

In the early Drosophila embryo, asymmetric distribution of transcription factors, established as a consequence of translational control of their maternally derived mRNAs, initiates pattern formation . For instance, translation of the uniformly distributed maternal hunchback (hb) mRNA is inhibited at the posterior to form an anterior-to-posterior protein concentration gradient along the longitud...
