Phenotypic uniformity of carrot androgenic lines of R1 generations was assessed in respect to several morphological traits in vegetative and generative stages. Seeds of R1 populations were obtained by self pollination of R0 androgenic plants derived by the use of anther culture technique from three donor cultivars: ‘HCM’, ‘CxC9900 F1’ and ‘Narbonne F1’. R1 plants of donor cultivar ‘HCM’ were ob...

F1-ATPase (F1) is the smallest rotary motor protein that couples ATP hydrolysis/synthesis to rotary motion in a highly reversible manner. F1 is unique compared with other motor proteins because of its high efficiency and reversibility in converting chemical energy into mechanical work. To determine the energy conversion mechanism of F1-ATPase, we developed a novel single-molecule manipulation t...

An extracellular fluid phase (C(f1)), aspirated by micropuncture techniques from the hypertrophic cell zone of calcifying epiphyseal certilage, has been characterized in a calcifying system in vitro in respect to the behavior of sedimenting and supernatant fractions after high speed ultracentrifugation. To perform these tests on the starting samples of 20 nl of C(f1), macroscopic analytical met...

Neonates respond poorly to conventional vaccines. This has been attributed, in part, to the immaturity of neonatal dendritic cells that lack full capacity for Ag presentation and T cell stimulation. We engineered an attenuated Salmonella Typhi strain to express and export the F1 Ag of Y. pestis (S. Typhi(F1)) and investigated its immunogenicity early in life using a heterologous prime-boost reg...

A proportion of patients with mitral stenosis have increased left atrial thrombin generation, with elevated left atrial but normal peripheral venous levels of prothrombin fragment 1+2 (F1+2). Whether this pattern of left atrial and venous F1+2 levels is related to limited spillover of F1+2 from the left atrium into the systemic circulation, or to washout of increased left atrial F1+2 production...

The prefrontal cortex (PFC) is known to be critical for inhibitory control of behavior, but the underlying mechanisms are unclear. Here, we propose that inhibitory control can be instantiated by an integral signal derived from working memory, another key function of the PFC. Specifically, we assume that an integrator converts excitatory input into a graded mnemonic activity that provides an inh...

We study the existence and shape preserving properties of a generalized Bernstein operator Bn fixing a strictly positive function f0, and a second function f1 such that f1/f0 is strictly increasing, within the framework of extended Chebyshev spaces Un. The first main result gives an inductive criterion for existence: suppose there exists a Bernstein operator Bn : C[a, b] → Un with strictly incr...

BACKGROUND/AIM The efficacy of flexible spectral imaging color enhancement (FICE) ch. 1 (F1) for the detection of ulcerative lesions and angioectasias in the small intestine with capsule endoscopy (CE) has been reported. In the present study, we evaluated whether F1 could detect incremental findings in patients with no findings in a standard review mode. PATIENTS AND METHODS In total, 52 pati...

GAP-43 is a fast-axonally transported protein whose expression correlates with periods of axon growth both during development and during regeneration. Similarities in molecular weight (43-47 kDa), pI (4.3-4.5), and aberrant behavior in acrylamide gels suggested that GAP-43 might be related or identical to protein F1, a protein kinase C substrate that has been shown to undergo a change in phosph...

Caryotypic analysis of the cells dividing in mouse parent-hybrid MLC showed an F1 hybrid cell proliferation, which varied depending upon the source of lymphoid cells used: strong in spleen MLC (sometimes equal to that of the parental cells), less marked in lymph node cell MLC, and most often absent in MLC between cortisone-resistant (CR) thymocytes. MLC between parental spleen cells and F1 CR t...
