Peripheral blood proteome biomarkers distinguish immunosuppressive features of cancer progression

open access: yesMolecular Oncology, EarlyView.
Immune status significantly influences cancer progression. This study used plasma proteomics to analyze benign 67NR and malignant 4T1 breast tumor models at early and late tumor stages. Immune‐related proteins–osteopontin (Spp1), lactotransferrin (Ltf), calreticulin (Calr) and peroxiredoxin 2 (Prdx2)–were associated with systemic myeloid‐derived ...

Lifting a Weak Poisson Bracket to the Algebra of Forms

open access: yes, 2016
We detail the construction of a weak Poisson bracket over a submanifold of a smooth manifold M with respect to a local foliation of this submanifold. Such a bracket satisfies a weak type Jacobi identity but may be viewed as a usual Poisson bracket on the

Laser-Aided Ceramic Bracket Debonding: A Comprehensive Review.

open access: yesJournal of lasers in medical sciences, 2016
Different techniques have been introduced for the removal of ceramic brackets. Since the early 1990s, lasers have been used experimentally for debonding ceramic brackets.

Brackets (parentheses) in formulas [PDF]

open access: yesBMJ, 2011
Each year, new health sciences postgraduate students in York are given a simple maths test. Each year the majority of them fail to calculate 20 – 3 × 5 correctly. According to the conventional rules of arithmetic, division and multiplication are done before addition and subtraction, so 20 − 3 × 5 = 20 − 15 = 5. Many students work from left to right and

Tumor clusters with divergent inflammation and human retroelement expression determine the clinical outcome of patients with serous ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Analysis of treatment‐naïve high‐grade serous ovarian carcinoma (HGSOC) and control tissues for ERVs, LINE‐1 (L1), inflammation, and immune checkpoints identified five clusters with diverse patient recurrence‐free survivals. An inflammation score was calculated and correlated with retroelement expression, where one novel cluster (Triple‐I) with high ...

Skein theory for SU(n)-quantum invariants

open access: yes, 2005
For any n>1 we define an isotopy invariant, _n, for a certain set of n-valent ribbon graphs Gamma in R^3, including all framed oriented links. We show that our bracket coincides with the Kauffman bracket for n=2 and with the Kuperberg's bracket for n=3 ...

From Peierls brackets to a generalized Moyal bracket for type-I gauge theories [PDF]

open access: yes, 2006
In the space-of-histories approach to gauge fields and their quantization, the Maxwell, Yang--Mills and gravitational field are well known to share the property of being type-I theories, i.e.
