The cystic fibrosis transmembrane conductance regulator (CFTR) attenuates sphingosine- 1-phosphate (S1P) signaling in resistance arteries and has emerged as a prominent regulator of myogenic vasoconstriction. This investigation demonstrates that S1P inhibits CFTR activity via adenosine monophosphate-activated kinase (AMPK), establishing a potential feedback link. In Baby Hamster Kidney (BHK) cells

Potentially significant shifts in the geographical patterns of vegetation are an expected result of climate change. However, the importance of local processes (e.g., dispersal, competition, or disturbance) has been often ignored in climate change modeling. We develop an individual-based simulation approach to assess how these mechanisms affect migration rate. We simulate the northward progression

The paper analyzes judicial dialogue (or judicial cross-reference) as a new form of international law-making and articulates itself around a new lexicon of international law grounded on concepts of authority, normativity and interaction, rather than sources, obligations and hierarchy in law. The aim is to offer a theoretical insight in the phenomenon of judicial cross-reference as a new avenue of

In a previous study, in order to investigate the effect of charge stratification on combustion behavior such as combustion efficiency and combustion phasing which also largely affects the emissions, an experiment was conducted in a heavy-duty compression ignition (CI) metal engine. The engine behavior and emission characteristics were studied in the transition from HCCI mode to PPC mode by varying

In modern day industry, robots are indispensable for achieving high production rates and competitiveness. In small and medium scale enterprises, where the production may shift rapidly, it is vital to be able to reprogram robots quickly. Kinesthetic teaching, also known as lead-through programming (LTP), provides a fast approach for teaching a trajectory. In this approach, a trajectory is demonstra

Flying insects frequently navigate through environments of different complexity. In this study, buff-tailed bumblebees (Bombus terrestris L.) were trained to fly along tunnels of different widths, from 60 to 240 cm. In tunnel widths of 60 and 120 cm, bumblebees control their lateral position by balancing the magnitude of translational optic flow experienced in the lateral visual field of each eye.

Recent years have seen growing interest in the streaming instability as a candidate mechanism to produce planetesimals. However, these investigations have been limited to small-scale simulations. We now present the results of a global protoplanetary disk evolution model that incorporates planetesimal formation by the streaming instability, along with viscous accretion, photoevaporation by EUV, FUV

OBJECTIVES: Bleeding complications associated with acute type A aortic dissection (aTAAD) are a well-known clinical problem. Here, we evaluated predictors of massive bleeding related to aTAAD and associated surgery and assessed the impact of massive bleeding on complications and survival. METHODS: This retrospective study of 256 patients used Blood Conservation Using Antifibrinolytics in a Randomi

Objective: To compare mortality and costs of health and social care between participants with access to care based on Comprehensive Geriatric Assessment (CGA) in an out-patient care setting with a control group receiving usual care only. The comparison was done 36 months after inclusion. Methods: Randomized controlled trial. Inclusion criteria: community-dwelling, aged ≥75 years, ≥3 hospitalisatio

The jet energy scale (JES) uncertainty is estimated using different methods at different pT ranges. In-situ techniques exploiting the pT balance between a jet and a reference object (e.g. Z or gamma) are used at lower pT, but at very high pT (> 2.5 TeV) there is not enough statistics for such in-situ techniques. A low JES uncertainty at high-pT is important in several searches for new phenomena, e

The need for more functionality and higher performance has increased the number of transistors to billions in current processors. A high number of transistors on the same chip area increases the power density, which in turn heats up the devices and lowers the life time of batteries. The increasing demand for devices relying on battery and harvested energies in the Internet of Things (IoT) era has

De flesta anser nog att kemi och speciellt teoretisk kemi är ett mycket komplext ämne, medan lera nog anses som ett begripligt koncept. Det man kanske inte tänker på är att många leror utgörs till stor del av elektrostatiskt laddade nanopartiklar där dess beteende kan förstås genom just ämnena kemi och teoretisk kemi. De laddade nanopartiklarna, även kallade lerplattor, är formade som tunna pannkaMany clay minerals consist of charged nanoplatelets that swell in an aqueous solution. The swelling and the microstructure depend on the type of clay mineral but are also dependent on, for example, the ionic composition and the temperature of the solution. The synthetic clay mineral Laponite and the natural clay mineral montmorillonite have been studied experimentally and theoretically. The swelli

The drug FK506 (tacrolimus, fujimycin) exerts its immunosuppressive effects by regulating the nuclear factor of the activated T-cell (NFAT) family of transcription factors. However, FK506 also exhibits neuroprotective effects, but its direct target proteins that mediate these effects have not been determined. To identify the target proteins responsible for FK506's neuroprotective effects, the drug
