ImmunoCellCycle-ID - a high-precision immunofluorescence-based method for cell cycle identification.

The cell cycle is a fundamental process essential for cell proliferation, differentiation and development. It consists of four major phases: G1, S, G2 and M. These phases collectively drive the reproductive cycle and are meticulously regulated by various proteins that play crucial roles in both the prevention and progression of cancer.

Phosphatidic acid directly activates mTOR and then regulates SREBP to promote ganoderic acid biosynthesis under heat stress in Ganoderma lingzhi.

Ganoderic acids (GAs), a class of secondary metabolites produced by the traditional medicinal mushroom Ganoderma, are a group of triterpenoids with superior biological activities. Heat stress (HS) is one of the most important environmental abiotic stresses. Understanding how organisms sense temperature and integrate this information into their metabolism is important for determining how organisms adapt to climate change and for applying this knowledge to breeding.

DHX9 SUMOylation is required for the suppression of R-loop-associated genome instability.

RNA helicase DHX9 is essential for genome stability by resolving aberrant R-loops. However, its regulatory mechanisms remain unclear. Here we show that SUMOylation at lysine 120 (K120) is crucial for DHX9 function.

Topiramate suppresses peri-infarct spreading depolarization and improves outcomes in a rat model of photothrombotic stroke.

Ischemic stroke can cause depolarized brain waves, termed peri-infarct depolarization (PID). Here, we evaluated whether topiramate, a neuroprotective drug used to treat epilepsy and alleviate migraine, has the potential to reduce PID. We employed a rat model of photothrombotic ischemia that can reliably and reproducibly induce PID and developed a combined electrocorticography-laser speckle contrast imaging (ECoG-LSCI) platform to monitor neuronal activity and cerebral blood flow (CBF) simultaneously.

Unleashing the Power of 2D MoS: In Situ TEM Study of Its Potential as Diffusion Barriers in Ru Interconnects.

This study presents the utilization of MoS as a diffusion barrier for metal interconnects, in situ transmission electron microscopy (TEM) observations are employed for comprehensive understanding. The diffusion-blocking ability of MoS is discussed by the diffusion and phase transformation between Ru and Si via TEM diffraction and imaging. When the sample is heated to a high temperature such that MoS loses the ability to block the diffusion, Si diffuses through the MoS into the Ru layer, leading to the formation of RuSi.

Image Preprocessing with Enhanced Feature Matching for Map Merging in the Presence of Sensing Error.

Autonomous robots heavily rely on simultaneous localization and mapping (SLAM) techniques and sensor data to create accurate maps of their surroundings. When multiple robots are employed to expedite exploration, the resulting maps often have varying coordinates and scales. To achieve a comprehensive global view, the utilization of map merging techniques becomes necessary.

Metformin improves sheep sperm cryopreservation via vitalizing the AMPK pathway.

Adenosine 5'-monophosphate (AMP)-activated protein kinase (AMPK) is a key regulator of sperm function and physiological metabolism. Metformin, an inexpensive and effective antioxidant, is known to play an important role in the activation of AMPK. Therefore metformin has potential to improve sperm cryopreservation.

Evaluation of environmental impact of red tide around Pearl River Estuary, Guangdong, China.

This paper presents a case study of red tide hazards around the Pearl River Estuary (PRE). Red tide hazards, meteorological data, and seawater monitoring data were collected from 1996 to 2020 at different locations around the PRE to investigate the internal and external factors influencing the occurrence of red tides. The enhancement of the assessment of estuarine trophic status (ASSETS) method enables us to evaluate the effects of meteorological factors and seawater eutrophication status on the red tide risk level.

Visible CCD Camera-Guided Photoacoustic Imaging System for Precise Navigation during Functional Rat Brain Imaging.

In photoacoustic (PA) imaging, tissue absorbs specific wavelengths of light. The absorbed energy results in thermal expansion that generates ultrasound waves that are reconstructed into images. Existing commercial PA imaging systems for preclinical brain imaging are limited by imprecise positioning capabilities and inflexible user interfaces.

Rebalancing TGFβ1/BMP signals in exhausted T cells unlocks responsiveness to immune checkpoint blockade therapy.

T cell dysfunctionality prevents the clearance of chronic infections and cancer. Furthermore, epigenetic programming in dysfunctional CD8 T cells limits their response to immunotherapies, including immune checkpoint blockade (ICB). However, it is unclear which upstream signals drive acquisition of dysfunctional epigenetic programs, and whether therapeutically targeting these signals can remodel terminally dysfunctional T cells to an ICB-responsive state.

Geometrical Parameter Effect on Plasmonic Scattering of Bimetallic Three-Layered Nanoshells.

Enhanced scattering from local surface plasmon resonance by light has attracted much attention due to its special applications in sensor, cell, and biological imaging . Here, we investigate the ratio of scattering to absorption in bimetallic three-layered nanoshells with different geometrical parameters using quasi-static theory. We show that the ratio of scattering to absorption strongly depends on the inner radius, shell thickness, middle dielectric function, and surrounding medium function.
