A heme-containing transmembrane ferric reductase domain (FRD) is found in bacterial and eukaryotic protein families, including ferric reductases (FRE), and NADPH oxidases (NOX). The aim of this study was to understand the phylogeny of the FRD superfamily. Bacteria contain FRD proteins consisting only of the ferric reductase domain, such as YedZ and short bFRE proteins. Full length FRE and NOX e...

Relatively small numbers of Sarcoma I cells were trans planted intradermally in A/WySn mice to study the course of growth when the size of the transplant is comparable to an early stage of spontaneous cancer. Transplants of 31 to 32,000 cells took one of three courses: no apparent growth; development of tumor followed by regression; on prognes sive growth. Transplants of 8,000 cells were the mo...

To test the hypothesis that o-hydroxy amines are proximate agents in chemical carcinogenesis paraffin pellets containing the hydrochlorides of 2-amino-l-fluorenol, 2-amino-3-fluorenol, 2-amino-5-fluorenol, 2-amino-7-fluorenol, 2-fluorenamine, and 1amino-2-naphthol were implanted into the urinary bladders of Swiss female mice. Paraffin pellets alone were implanted as controls. Histological exami...

A control mechanism that limits nuclear division is pres ent in contact-inhibited nontumorigenic mouse BALB/3T3 cells and mouse embryo fibroblasts. In the absence ofcytoplasmic division, 3T3 and mouse embryo fibroblast cells may undergo nuclear division once or occasionally twice and then stop. Also, there is no increase in the frequency of premature chromosome condensation. In non-contactinhib...

The Cooper pair box qubit of a two-junction-SQUID configuration enables the readout of the qubit states by probing the effective Josephson inductance of the SQUID. This is realized by coupling the qubit to a high-Q tank circuit which induces a small alternating supercurrent in the SQUID loop. The effect of a small (but finite) geometrical inductance of the loop on the eigenstates of the system ...

The frequency difference between signal-under-test and reference signal in phase demodulation will affect the result of the actual phase noise measurement. In order to eliminate the effect, an algorithm for both eliminating the frequency difference and extracting the phase noise of the signal-under-test is presented. Simulation and experiment results show that this algorithm is effective. By us...

The Flp and Cre recombinases are members of the integrase family of tyrosine recombinases. Each protein consists of a 13 kDa NH(2)-terminal domain and a larger COOH-terminal domain that contains the active site of the enzyme. The COOH-terminal domain also contains the major determinants for the binding specificity of the recombinase to its cognate DNA binding site. All family members cleave the...

Background:to analyze the epidemiological behavior of malaria, in relation to armed con-flicts presented on Pacific coast Nariño (PCN).Methodology: there was a multi-group ecological study with secondary information sour-ce, frequency malaria (PCN) population, and relationship region, resulting from country’s internal conflict, 2003 2017, analyzed.Results: Armed conflict affects structure healt...

Low-level laser therapy (LLLT) may have utility in the management of side effects radiation head and neck cancer (HNC) patients. Although evidence suggests that LLLT is safe treatment for HNC patients, more research imperative vigilance remains warranted to de-tect any potential adverse on outcomes survival The purpose this study was evaluate effect transcranial low-level irradiation (LLLI) com...
