The nature of the anomalous metal state has been a major puzzle in condensed matter physics for more than three decades. Here, we report systematic investigation and modulation of the anomalous metal states in high-temperature interface superconductor FeSe films on SrTiO_{3} substrate. Remarkably, under zero magnetic field, the anomalous metal state persists up to 20 K in pristine FeSe films, an exceptionally high temperature standing out from previous observations.

To date, dozens of pilot-scale microbial fuel cell (MFC) devices have been successfully developed worldwide for treating various types of wastewater. The availability and configurations of separators are determining factors for the economic feasibility, efficiency, sustainability, and operability of these devices. Thus, the concomitant advances between the separators and pilot-scale MFC configurations deserve further clarification.

Article Synopsis
  • Sensor-based gait analysis was used to study how anxiety affects walking in patients with Parkinson's disease (PD), revealing that anxiety can interfere with gait significantly.
  • A total of 144 PD patients were compared, with those having anxiety showing shorter strides and slower walking speed, particularly when not multitasking.
  • The research emphasized that anxiety notably worsens certain gait parameters, suggesting that addressing anxiety could improve treatment results for PD patients.

  • * An observational study of 15,792 individuals found that low serum potassium and magnesium levels were associated with a higher risk of AF, while increased phosphate levels were also linked to greater incidence, but calcium levels showed no correlation.
  • * Despite these associations, the study concluded that serum electrolytes are not causal factors for AF development, suggesting they could be used as prognostic indicators rather than direct causes.

Early repolarization syndrome (ERS) is defined as occurring in patients with early repolarization pattern who have survived idiopathic ventricular fibrillation with clinical evaluation unrevealing for other explanations. The pathophysiologic basis of the ERS is currently uncertain. The objective of the present study was to examine the electrophysiological mechanism of ERS utilizing induced pluripotent stem cells (iPSCs) and CRISPR/Cas9 genome editing.

  • NUP96 is found to be crucial for how plants respond to salt stress, influencing gene expression related to salt tolerance.
  • The study revealed that a mutant of Arabidopsis lacking NUP96 shows sensitivity to salt, impacting growth and ion balance, while overexpressing NUP96 counteracts these effects.
  • RNA sequencing indicates that many genes related to salt response are improperly regulated in the absence of NUP96, suggesting its role in the transportation of important regulators between the nucleus and cytosol.

The requirements for drilling bentonites are tightening due to ever-increasing demands for petroleum resources, coupled with cost and reaction technology constraints. In addition to raising the risk of drilling, bentonite's poor performance also raises the possibility of safety incidents and significant financial losses. Organically modified bentonites effectively reduce the consumption of drilling fluids, conserve resources, and lessen environmental effects.

Electroactive biofilms (EBs) engage in complex electron transfer and storage processes involving intracellular and extracellular mediators with temporary electron storage capabilities. Consequently, electroactive biofilms exhibit pseudocapacitive behaviors during substrate degradation processes. However, comprehensive systematic research in this area has been lacking.

Cholangiocarcinoma (CCA) is resistant to systemic chemotherapies that kill malignant cells mainly through DNA damage responses (DDRs). Recent studies suggest that the involvement of 2-oxoglutarate (2-OG) dependent dioxygenases in DDRs may be associated with chemoresistance in malignancy, but how 2-OG impacts DDRs in CCA chemotherapy remains elusive. We examined serum 2-OG levels in CCA patients before receiving chemotherapy.

The infinite-layer nickelates, isostructural to the high-T cuprate superconductors, have emerged as a promising platform to host unconventional superconductivity and stimulated growing interest in the condensed matter community. Despite considerable attention, the superconducting pairing symmetry of the nickelate superconductors, the fundamental characteristic of a superconducting state, is still under debate. Moreover, the strong electronic correlation in the nickelates may give rise to a rich phase diagram, where the underlying interplay between the superconductivity and other emerging quantum states with broken symmetry is awaiting exploration.

  • * The study identified two stages of fouling behavior: an initial sharp decrease in performance followed by a stable phase, with bound-extracellular polymeric substances (bEPS) leading to the greatest flux decline.
  • * Chemical analyses indicated that the composition of algal foulants—particularly the ratio of carbohydrates to proteins—significantly affects fouling, with soluble-extracellular polymeric substances (sEPS) playing a larger role in fouling for S.

Aquaporins are water channel proteins that play an essential role in plant growth and development. Despite extensive functional characterization of aquaporins in model plants such as Arabidopsis, their contributions to abiotic stress tolerance in non-model plants are still poorly understood. As a close relative of Arabidopsis thaliana, Eutrema salsugineum is an excellent model for studying salt tolerance.

Emergence delirium (ED) is a severe postoperative complication that increases the risk for injury, self-extubation, and hemorrhage. Inhalational maintenance of anesthesia is a risk factor for ED in pediatric patients, but its impact in adults is undefined. This meta-analysis compares the incidence of ED between inhalational and propofol-based intravenous maintenance of anesthesia.

Background And Aims: Cholangiocarcinoma (CCA) is a highly lethal disease without effective therapeutic approaches. The whole-genome sequencing data indicate that about 20% of patients with CCA have isocitrate dehydrogenase 1 (IDH1) mutations, which have been suggested to target 2-oxoglutarate (OG)-dependent dioxygenases in promoting CCA carcinogenesis. However, the clinical study indicates that patients with CCA and mutant IDH1 have better prognosis than those with wild-type IDH1, further complicating the roles of 2-OG-dependent enzymes.
