Determinants of Financial vs. Non Financial Stock Returns: Evidence from Istanbul Stock Exchange [PDF]

open access: yes, 2009
We estimate a four-factor model for a sample of financial and nonfinancial firms traded on the Istanbul Stock Exchange (ISE). The factors relate to market return, interest, inflation and exchange rates.

A Novel Microfluidic System for 3D Epidermis and Full‐Thickness Skin Growth for Nanoparticle Safety Assessment

open access: yesAdvanced Healthcare Materials, EarlyView.
This work presents a novel, dynamically perfused, configurable microfluidic system for epidermis‐only (E and full‐thickness skin (FT SoC) growth, emulating human skin structure and barrier function. Upon TiO2 nanoparticle exposure, the system reveals compromised barrier integrity, reduced metabolic activity, increased permeability, and chemokine‐driven

Metallofullerenol Sc3N@C80(OH)18: A New Generation Radioprotector Protecting Human Erythrocytes Against Multiple Biochemical Damage Modes Upon Gamma Irradiation, Identifying It as a Scavenger of Short‐ and Long‐Lived Radicals

open access: yesAdvanced Healthcare Materials, EarlyView.
Metallofullerenol Sc3N@C80(OH)18 demonstrates strong radioprotective properties as a scavenger of both short‐ and long‐lived radicals. The study reveals protection of human erythrocytes from γ‐radiation–induced biochemical damage via post‐irradiation removal of primary and secondary reactive oxidants, supported by pulse radiolysis kinetics.

The Dynamic Relationship between Stock Prices and Exchange Rates: evidence for Brazil [PDF]

open access: yes
This paper studies the dynamic relationship between stock prices and exchange rates in the Brazilian economy. We use recently developed unit root and cointegration tests, which allow endogenous breaks, to test for a long run relationship between these ...

Spherical Skin Model: Stratified Co‐Culture of Fibroblasts and Keratinocytes on Spherical Beads Toward Compound Screening

open access: yesAdvanced Healthcare Materials, EarlyView.
Models of the human skin must combine the relevant biological contents and suitable biomaterials with the correct spatial organization. Performing compound screening on such in vitro models also requires fast and reproducible production methods of the models.

Shanghai Stock Prices as Determined by the Present Value Model [PDF]

open access: yes
Derived from the present-value model of stock prices, our model implies that the log stock price is a linear function of expected log dividends and the expected rate of growth of dividends where expectations are formed adaptively. The model explains very
