Vpliv zrnatosti brusnega papirja na emisijo formaldehida iz ivernih plošč

Acta Silvae et Ligni, 2017
Sanding is an important stage of wood-based panel production, where the primary goal is to achieve a desired thickness as well as appropriate smoothness of the surface.

Impact of Ventilation on Indoor Air Quality: Singular Behaviour of Formaldehyde

Chemical Engineering Transactions, 2019
Combined with material emission, ventilation has a direct impact on volatile organic compound (VOC) concentrations in indoor environments. In this work, the impact of ventilation on various VOC emission rates relative to wood particleboard is assessed ...

Measuring Method of Formaldehyde Emission for Plywood

Journal of the Korean Wood Science and Technology, 2010
합판의 경우에는 제조 시 접착제가 각 단판의 전체 면에 도포되는 것이 아니라 접착 면에만 도포되므로 접착층을 따라서 접착제가 분포하게 된다. 따라서 섬유판이나 파티클보드의 경우와는 달리 전체 표면을 통하여 포름알데히드가 방산되지 않고 접착층을 따라서 방산된다고 판단되어진다. 따라서 기존의 KS M 1998-4 : 2005 방법으로 포름알데히드방산량을 측정하는 방법이 적절하지 않을 수도 있다고 판단되었다. 이에 본 연구에서는 동일한 조건에서 제조한 합판을 4가지 측정 조건에 따라 포름알데히드방산량을 측정하여 이들의 상관관계를 검토하였다.

Proteasome inhibitor, ixazomib prevents topoisomerase‐I degradation and reverses irinotecan resistance in colorectal cancer

Molecular Oncology, EarlyView.
Ixazomib inhibits proteasome‐mediated degradation of topoisomerase I induced by irinotecan, thereby restoring drug sensitivity and promoting tumor cell death in colorectal cancer. Irinotecan, a topoisomerase I (topoI) inhibitor, is widely used for colorectal cancer, but resistance remains a major clinical challenge.

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Formaldehyde emission and high-temperature stability of cured urea-formaldehyde resins

Journal of Wood Science, 2000
A test method for measuring formaldehyde from urea-formaldehyde (UF) resins at high temperature was developed and used to assess the influence of the reaction pH on the formaldehyde emission and heat stability of the cured resins. Additionally, solid-state13C CP/MAS nuclear magnetic resonance (NMR) techniques were used to investigate the structure of ...

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Effects of Nanoclay Modification with Aminopropyltriethoxysilane (APTES) on the Performance of Urea–formaldehyde Resin Adhesives

BioResources, 2023
Urea-formaldehyde (UF) resins, as the most common adhesives for wood-based composites, emit formaldehyde, which is forcing producers to find a solution to this problem. Using scavengers is a practical way of reducing formaldehyde emissions, but sometimes
