Diet composition of batoids on the continental shelf off Nayarit and Sinaloa, Mexico
Ciencias Marinas, 2012 Since elasmobranchs are frequently apex predators in marine ecosystems, information on their diet is essential for understanding trophic relationships in these systems.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity
Molecular Oncology, EarlyView.Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Heat transparent high intensity high efficiency solar cell [PDF]
, 1982 An improved solar cell design is described. A surface of each solar cell has a plurality of grooves. Each groove has a vertical face and a slanted face that is covered by a reflecting metal.

Molecular Oncology, EarlyView.Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

Sources of sub-GZK cosmic rays [PDF]
, 2002 We analyze the existing evidence that BL Lacertae objects (BL Lacs) are sources of the highest-energy cosmic rays. We argue that three independent signatures observed in the real data -- (1) improvement of correlations with corrections of trajectories ...

Cosmic-Ray Induced Diffuse Emissions from the Milky Way and Local Group Galaxies
, 2011 Cosmic rays fill up the entire volume of galaxies, providing an important source of heating and ionisation of the interstellar medium, and may play a significant role in the regulation of star formation and galactic evolution.

The PI3Kδ inhibitor roginolisib (IOA‐244) preserves T‐cell function and activity
Molecular Oncology, EarlyView.Identification of novel PI3K inhibitors with limited immune‐related adverse effects is highly sought after. We found that roginolisib and idelalisib inhibit chronic lymphocytic leukemia (CLL) cells and Treg suppressive functions to similar extents, but roginolisib affects cytotoxic T‐cell function and promotion of pro‐inflammatory T helper subsets to a

Ontogenetic development of storied ray pattern in cambium of Hippophaë rhamnoides L.
Acta Societatis Botanicorum Poloniae, 2011 Storied pattern, in the arrangement of both fusiform initials and the rays in cambium of Hippophae rhamnoides, develops in ontogeny relatively quickly and becomes clearly visible in terminal parenchyma of third and fourth annual ring.

Testing Fundamental Physics with High-Energy Cosmic Rays [PDF]
, 2000 Cosmic rays may provide opportunities for probing fundamental physics. For example, ultra-high-energy cosmic rays might originate from the decays of metastable heavy particles, and astrophysical gamma rays can be used to test models of quantum gravity ...
