ROLE OF STEM CELL FACTOR IN THE REACTIVATION OF HUMAN FETAL HEMOGLOBIN

open access: yesMediterranean Journal of Hematology and Infectious Diseases, 2009
In humans the switch from fetal to adult  hemoglobin (HbF→ HbA) takes place in the perinatal and postnatal period, determining the progressive replacement of HbF with HbA synthesis ( i.e., the relative HbF content in red blood cells decreases from 80-90%

Beltrami fields with a nonconstant proportionality factor are rare [PDF]

open access: yes, 2014
We consider the existence of Beltrami fields with a nonconstant proportionality factor $f$ in an open subset $U$ of $\mathbf{R}^3$. By reformulating this problem as a constrained evolution equation on a surface, we find an explicit differential equation ...

$$F$$ F -Factors in Hypergraphs Via Absorption

open access: yesGraphs and Combinatorics, 2014
Given integers $ n \ge k >l \ge 1 $ and a $k$-graph $F$ with $|V(F)|$ divisible by $n$, define $t_l^k(n,F)$ to be the smallest integer $d$ such that every $k$-graph $H$ of order $n$ with minimum $l$-degree $δ_l(H) \ge d $ contains an $F$-factor. A classical theorem of Hajnal and Szemerédi implies that $t^2_1(n,K_t) = (1-1/t)n$ for integers $t$. For $

πe3 Form Factor f- Near the Mass Shell

open access: yesAdvances in High Energy Physics, 2015
The generalized Ward-Takahashi identity (gWTI) in the pion sector for broken isotopic symmetry is derived and used for the model-independent calculation of the longitudinal form factor f- of the πe3 vector vertex.

Shot Noise in Ballistic Graphene [PDF]

open access: yes, 2008
We have investigated shot noise in graphene field effect devices in the temperature range of 4.2--30 K at low frequency ($f$ = 600--850 MHz). We find that for our graphene samples with large width over length ratio $W/L$, the Fano factor $\mathfrak{F ...

LIDAR‐based F‐factor for wind shear alerting: different smoothing algorithms and application to departing flights

open access: yes, 2014
Rapid fluctuations of wind shear hazard factor (or F‐factor) calculated from the headwind profile measured by Doppler Light Detection and Ranging (LIDAR) may make it difficult for use in wind shear alerting at an airport such as Hong Kong International ...

Serum antibodies from Parkinson's disease patients react with neuronal membrane proteins from a mouse dopaminergic cell line and affect its dopamine expression

open access: yesJournal of Neuroinflammation, 2006
Evidence exists suggesting that the immune system may contribute to the severity of idiopathic Parkinson's disease (IPD). The data presented here demonstrates that antibodies in the sera of patients with IPD have increased binding affinity to ...
