CHEMICAL COMPOSITION, CRYSTALLINITY, AND THERMAL DEGRADATION OF BLEACHED AND UNBLEACHED KENAF BAST (Hibiscus cannabinus) PULP AND NANOFIBERS

open access: yesBioResources, 2009
Kenaf (Hibiscus cannabinus) nanofibers were isolated from unbleached and bleached pulp by a combination of chemical and mechanical treatments. The chemical methods were based on NaOH-AQ (anthraquinone) and three-stage bleaching (DEpD) processes, whereas ...

Early stages of tooth development in the harbor porpoise Phocoena phocoena

open access: yesThe Anatomical Record, EarlyView.
Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

A Multifaceted Interplay Among Hemophagocytosis, Interleukin‐18, and Type I Interferon Distinguishes Still Disease From Other Autoinflammatory Diseases

open access: yesArthritis &Rheumatology, EarlyView.
Objective The unknown pathophysiology and the lack of specific features for systemic juvenile idiopathic arthritis and adult‐onset Still disease (collectively known as Still disease; SD) delay diagnosis and appropriate treatment. The goal of this study was to identify features and mechanisms that distinguish SD from other systemic autoinflammatory ...

Vitamins as potent cancer treatments through regulating the activity and expression of MMP‐2 and MMP‐9

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Vitamins could regulate both MMP‐2 and MMP‐9 expression and activity through transcriptional and MAPK signaling pathway modulation. This study highlights the potential of vitamins as low‐toxicity therapeutic or adjunct agents for targeting MMP‐mediated cancer progression. Abstract Matrix metalloproteinases (MMP‐2 and MMP‐9) are key regulators of cancer
