International trade and structural change [PDF]

open access: yesJournal of International Economics, 1997
Abstract In light of the substantial movement towards trade liberalization during the postwar period, this paper attempts to determine if, and when, countries experienced statistically significant changes in the paths of their export-GDP and import-GDP ratios.

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

open access: yesMolecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

A model structure on internal categories in simplicial sets [PDF]

open access: yes, 2015
We put a model structure on the category of categories internal to simplicial sets whose weak equivalences are reflected by the nerve functor to bisimplicial sets with Rezk's model structure. This model structure is shown to be Quillen equivalent to Rezk'

Unionization Structures in International Oligopoly [PDF]

open access: yesLABOUR, 2012
Abstract. We examine how competition in international markets affects a union's choice of wage regime, which can be either uniform or discriminatory. Firms are heterogeneous with regard to international competition. When unions choose their wage regimes sequentially, a discriminatory outcome becomes more likely when international competition increases.

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

open access: yesMolecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Fabrication and characterization of multi-scale coated boron powders with improved combustion performance: A brief review

open access: yesDefence Technology
Boron has high mass and volume calorific values, but it is difficult to ignite and has low combustion efficiency. This literature review summarizes the strategies that are used to solve the above-mentioned problems, which include coatings of boron by ...
