Initiation and emerging complexity of the collagen network during prenatal skeletal development [PDF]

open access: yesEuropean Cells & Materials, 2020
The establishment of a complex collagen network is critical for the architecture and mechanical properties of cartilage and bone. However, when and how the key collagens in cartilage and bone develop has not been characterised in detail.

Baryon wave function in large-Nc QCD: Universality, nonlinear evolution equation and asymptotic limit

open access: yes, 2005
The 1/Nc expansion is formulated for the baryon wave function in terms of a specially constructed generating functional. The leading order of this 1/Nc expansion is universal for all low-lying baryons [including the O(1/Nc) and O(Nc^0) excited resonances]

Non-commutative deformation of Chern-Simons theory [PDF]

open access: yes, 2020
The problem of the consistent definition of gauge theories living on the non-commutative (NC) spaces with a non-constant NC parameter $\Theta(x)$ is discussed.

Inpatient Food Insecurity and Pediatric Hematology Oncology Hospitalization Outcomes

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Children with cancer and blood disorders are at risk for food insecurity (FI). We aimed to describe the association of inpatient food insecurity (IFI) and hospitalization outcomes among patients admitted to the pediatric hematology oncology service. Of 325 caregivers screened for IFI, 60 (18.6%) screened positive.

Enhanced non-quark-antiquark and non-glueball Nc behavior of light scalar mesons [PDF]

open access: yes, 2011
We show that the latest and very precise dispersive data analyses require a large and very unnat- ural fine-tuning of the 1/Nc expansion at Nc = 3 if the f_0(600) and K(800) light scalar mesons are to be considered predominantly quark-antiquark states ...

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Natural products as starting points for future anti-malarial therapies: going back to our roots?

open access: yesMalaria Journal, 2011
Background The discovery and development of new anti-malarials are at a crossroads. Fixed dose artemisinin combination therapy is now being used to treat a hundred million children each year, with a cost as low as 30 cents per child, with cure rates of ...

Deterministic Cramer-Rao bound for strictly non-circular sources and analytical analysis of the achievable gains

open access: yes, 2015
Recently, several high-resolution parameter estimation algorithms have been developed to exploit the structure of strictly second-order (SO) non-circular (NC) signals.

The PI3Kδ inhibitor roginolisib (IOA‐244) preserves T‐cell function and activity

open access: yesMolecular Oncology, EarlyView.
Identification of novel PI3K inhibitors with limited immune‐related adverse effects is highly sought after. We found that roginolisib and idelalisib inhibit chronic lymphocytic leukemia (CLL) cells and Treg suppressive functions to similar extents, but roginolisib affects cytotoxic T‐cell function and promotion of pro‐inflammatory T helper subsets to a

Temporal trends in breast cancer presentation in the third world

open access: yesJournal of Experimental & Clinical Cancer Research, 2008
Background Third world breast cancer is characterized by late presentation, occurrence at relatively young ages and dismal mortality. This poor outcome has encouraged patients to patronize quacks and alternative healers.
