Human telomere biology: A contributory and interactive factor in aging, disease risks, and protection

open access: yesScience, 2015
Telomeres are the protective end-complexes at the termini of eukaryotic chromosomes. Telomere attrition can lead to potentially maladaptive cellular changes, block cell division, and interfere with tissue replenishment.

Nano-palladium is a cellular catalyst for in vivo chemistry

open access: yesNature Communications, 2017
Palladium (Pd) is a well-known catalyst in organic chemistry but its use in nanomedicine is limited. Here, the authors design a Pd nanoparticle that triggers the activation of an antitumour prodrugin vivo, which shows efficacy and improves toxicity ...

Identification of functional and diverse circulating cancer‐associated fibroblasts in metastatic castration‐naïve prostate cancer patients

open access: yesMolecular Oncology, EarlyView.
Cancer‐associated fibroblasts (CAFs) promote cancer growth, invasion (metastasis), and drug resistance. Here, we identified functional and diverse circulating CAFs (cCAFs) in patients with metastatic prostate cancer (mPCa). cCAFs were found in higher numbers and were functional and diverse in mPCa patients versus healthy individuals, suggesting their ...

Botulinum Neurotoxins: Biology, Pharmacology, and Toxicology

open access: yesPharmacological Reviews, 2017
The study of botulinum neurotoxins (BoNT) is rapidly progressing in many aspects. Novel BoNTs are being discovered owing to next generation sequencing, but their biologic and pharmacological properties remain largely unknown.

Circulating tumor cells: advancing personalized therapy in small cell lung cancer patients

open access: yesMolecular Oncology, EarlyView.
Small cell lung cancer (SCLC) is an aggressive form of lung cancer that spreads rapidly to secondary sites such as the brain and liver. Cancer cells circulating in the blood, “circulating tumor cells” (CTCs), have demonstrated prognostic value in SCLC, and evaluating biomarkers on CTCs could guide treatment decisions such as for PARP inhibitors ...

Julian Huxley, general biology and the London Zoo, 1935–42

open access: yesNotes and Records of the Royal Society, 2010
While Secretary of the Zoological Society of London (1935–42), Julian Huxley used that institution to undertake several types of reform related to his promotion of ‘general biology’.

Single-cell barcode analysis provides a rapid readout of cellular signaling pathways in clinical specimens

open access: yesNature Communications, 2018
Diagnostic tests need optimization to avoid invasive and costly repeated biopsies. Here the authors present an antibody-DNA barcoding approach where harvested single cells can be re-stained through custom oligonucleotide-fluorophore conjugates, enabling ...

Developing a Web-Based Learning (E-Learning) in General Biology Subjects with Joomla Program

open access: yesBiosfer, 2018
Web-based learning has been widely used as learning resources. Developing these learning resources is believed to provide beneficial for students. Therefore, this research was aimed to develop a web-based learning source for General Biology Course.

Foundations of biology [PDF]

open access: yesarXiv, 2014
It is often stated that there are no laws in biology, where everything is contingent and could have been otherwise, being solely the result of historical accidents. Furthermore, the customary introduction of fundamental biological entities such as individual organisms, cells, genes, catalysts and motors remains largely descriptive; constructive ...

Controlled vocabularies and semantics in systems biology [PDF]

open access: yes, 2011
The use of computational modeling to describe and analyze biological systems is at the heart of systems biology. Model structures, simulation descriptions and numerical results can be encoded in structured formats, but there is an increasing need to ...
