Single-layer HNbO with strong and nearby Lewis and Brønsted acid sites boosts amide bond hydrolysis for urease mimicking.

Urea pollution is a growing environmental concern, and its removal catalytic hydrolysis is challenging due to the resonance-stabilized amide bonds. In nature, this reaction is catalyzed by ureases in many soil bacteria. However, the remedy of this problem with natural enzymes is not feasible as they are easily denatured and require high costs for both preparation and storage.

Nature gives us strength: exposure to nature counteracts ego-depletion.

Previous research rarely investigated the role of physical environment in counteracting ego-depletion. In the present research, we hypothesized that exposure to natural environment counteracts ego-depletion. Three experiments were conducted to test this hypothesis.

The impact of rumination on internal attention switching.

The present study explored the nature of attention control problems associated with ruminative traits. Experiment 1 aimed to establish the validity of a modified mental counting task that assesses individuals' ability to switch attention between internal mental representations. Reaction time and brain activity (event related potential; ERP) measures were examined, and results showed that the task was sensitive to internal attention switching effects.

Task- and self-related pathways to deep learning: the mediating role of achievement goals, classroom attentiveness, and group participation.

Background: The expectancy-value and achievement goal theories are arguably the two most dominant theories of achievement motivation in the contemporary literature. However, very few studies have examined how the constructs derived from both theories are related to deep learning. Moreover, although there is evidence demonstrating the links between achievement goals and deep learning, little research has examined the mediating processes involved.

Azygous vein aneurysm: CT scan follow-up.

We present a case of azygous vein aneurysm diagnosed by dynamic contrast-enhanced CT scan. The patient refused surgical resection, although it was offered as one of the treatment options due to theoretical risks of rupture and pulmonary embolism. The patient has been managed conservatively for 4 years with no untoward outcomes.

Gastrointestinal stromal tumor of rectum: a report of 2 cases.

The specific c-kit protein (CD117)-positive gastrointestinal stromal tumor (GIST) of the rectum has been sporadically reported in pathology literature, but its radiologic features have never been thoroughly described. We present 2 cases of histologically and immunohistochemically confirmed rectal GISTs. Their clinical and multimodality imaging features are illustrated, and the relevant literature is reviewed and discussed.
