Nut production in Bertholletia excelsa across a logged forest mosaic: implications for multiple forest use [PDF]

open access: yes, 2015
Although many examples of multiple-use forest management may be found in tropical smallholder systems, few studies provide empirical support for the integration of selective timber harvesting with non-timber forest product (NTFP) extraction.

Outcomes and Surgical Management of Malignant Rhabdoid Tumor of the Kidney: A Report From the Pediatric Surgical Oncology Research Collaborative

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Malignant rhabdoid tumor of the kidney (MRTK) is a rare, aggressive tumor seen in young children. The optimal timing of resection for locally advanced tumors is not well‐defined. The purpose of this study is to evaluate modern oncologic outcomes and the impact of surgical timing. Methods A multicenter retrospective review was performed

Research on synthetic rope and its future in timber harvesting [PDF]

open access: yes, 2006
Steel wire rope is used for many logging applications. It has served the industry well in terms of strength, durability, and longevity. However, steel wire rope is difficult to use because it is stiff, heavy, and unyielding.

Inhibiting stearoyl‐CoA desaturase suppresses bone metastatic prostate cancer by modulating cellular stress, mTOR signaling, and DNA damage response

open access: yesFEBS Letters, EarlyView.
Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

The matrix equation \(\log (XY)=\log (X)+\log (Y)\)

open access: yesLinear Algebra and its Applications, 2010
Let \(X,Y\) be \(n\times n\) complex matrices such that \(X,Y,XY\) have no eigenvalues on \(\mathbb R^-\) and \(\log (XY)=\log (X)+\log (Y)\). The authors prove that if \(n=2\), or if \(n\geqslant 3\) and \(X,Y\) are simultaneously triangularizable, then \(X,Y\) commute. In both cases the problem is reduced to a result in complex analysis.

Roadless space and logging in intact forest landscapes of the Congo Basin [PDF]

open access: yes, 2016
Background: Forest degradation in tropical regions is often associated with roads built for selective logging. Forest areas that are not accessible by roads are considered valuable because they provide habitat that is not immediately impacted by major ...

Aggressive prostate cancer is associated with pericyte dysfunction

open access: yesMolecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).
