Observation of double resistance anomalies and excessive resistance in mesoscopic superconducting Au$_{0.7}$In$_{0.3}$ rings with phase separation [PDF]

open access: yesarXiv, 2004
We have measured mesoscopic superconducting Au$_{0.7}$In$_{0.3}$ rings prepared by e-beam lithography and sequential deposition of Au and In at room temperature followed by a standard lift-off procedure. In samples showing no Little-Parks resistance oscillations, highly unusual double resistance anomalies, two resistance peaks found near the onset of ...

Advanced glycation end products promote the release of endothelial cell‐derived mitocytosis

open access: yesFEBS Open Bio, EarlyView.
Under diabetic conditions, AGEs induce mitochondrial damage in HUVECs, activating migrasome‐mediated mitocytosis. Migrasomes encapsulate damaged mitochondria and are released into the extracellular space, facilitating intercellular mitochondrial transfer.

ارزیابی شیوع ژن‌های pbp1a، pbp2x و pbp2b در ایجاد مقاومت به پنی‌سیلین در سویه‌های Streptococcus pneumoniae جدا شده از بخش‌های مراقبت ویژه

open access: yesمجله دانشکده پزشکی اصفهان, 2012
Background: A major concern about S. pneumoniae is the emergence of resistance to antibiotics, especially to penicillin. The aim of this study was to assess the role of PBPs gene in penicillin resistance of S.

Matrigel inhibits elongation and drives endoderm differentiation in aggregates of mouse embryonic stem cells

open access: yesFEBS Open Bio, EarlyView.
Stem cell‐based embryo models (SCBEMs) are valuable to study early developmental milestones. Matrigel, a basement membrane matrix, is a critical substrate used in various SCBEM protocols, but its role in driving stem cell lineage commitment is not clearly defined.

RhoA and Rac1 as Mechanotransduction Mediators in Colorectal Cancer

open access: yesAdvanced Biology, EarlyView.
Analysing RhoA and Rac1 protein levels in Colorectal cancer (CRC) samples under mechanical strain highlights their potential as diagnostic markers. Monitoring their activity could offer valuable insights into how cancer spreads, paving the way for new approaches to better understand and diagnose colorectal cancer.

HIV drug resistance: problems and perspectives [PDF]

open access: yesarXiv, 2012
Access to combination antiretroviral treatment (ART) has improved greatly over recent years. At the end of 2011, more than eight million HIV infected people were receiving antiretroviral therapy in low-income and middle-income countries. ART generally works well in keeping the virus suppressed and the patient healthy.

Scalable Manufacturing of Radiation‐Tolerant Potentiometric Electrodes: A Systematic Transition from Laboratory to Semiautomated Fabrication

open access: yesAdvanced Engineering Materials, EarlyView.
Laboratory protocols for producing thin‐film pH electrodes for sterilized single‐use technologies have been successfully developed into a semiautomated workflow, with higher throughput and precision of membrane thickness. Accuracies are within 0.05 pH units versus ground truth, and uncertainty analysis reveals the largest sources of error to be derived
