Block copolymer self-assembly derived mesoporous magnetic materials with three-dimensionally (3D) co-continuous gyroid nanostructure.

Magnetic nanomaterials are gaining interest for their many applications in technological areas from information science and computing to next-generation quantum energy materials. While magnetic materials have historically been nanostructured through techniques such as lithography and molecular beam epitaxy, there has recently been growing interest in using soft matter self-assembly. In this work, a triblock terpolymer, poly(isoprene--styrene--ethylene oxide) (ISO), is used as a structure directing agent for aluminosilicate sol nanoparticles and magnetic material precursors to generate organic-inorganic bulk hybrid films with co-continuous morphology.

Association of Preoperative High-Intensity Interval Training With Cardiorespiratory Fitness and Postoperative Outcomes Among Adults Undergoing Major Surgery: A Systematic Review and Meta-Analysis.

Importance: Preoperative high-intensity interval training (HIIT) is associated with improved cardiorespiratory fitness (CRF) and may improve surgical outcomes.

Objective: To summarize data from studies comparing the association of preoperative HIIT vs standard hospital care with preoperative CRF and postoperative outcomes.

Data Sources: Data sources included Medline, Embase, Cochrane Central Register of Controlled Trials Library, and Scopus databases with no language constraints, including abstracts and articles published before May 2023.

The Promise of Soft-Matter-Enabled Quantum Materials.

The field of quantum materials has experienced rapid growth over the past decade, driven by exciting new discoveries with immense transformative potential. Traditional synthetic methods to quantum materials have, however, limited the exploration of architectural control beyond the atomic scale. By contrast, soft matter self-assembly can be used to tailor material structure over a large range of length scales, with a vast array of possible form factors, promising emerging quantum material properties at the mesoscale.

A star-shaped POSS-containing polymer for cleaner leather processing.

A water-based silsesquioxane (POSS)-containing polymer, POSS-PAA, was synthesized by using octavinyl-POSS (V-POSS) and acrylic acid (AA) via interfacial polymerization. The TEM of POSS-PAA showed that the polymer formed a core-shell structure in aqueous solution and was well-dispersed. The star-shaped POSS-PAA and linear PAA were both tanned with 3.

Moisture-Responsive Wrinkling Surfaces with Tunable Dynamics.

The wrinkle dynamics (such as reversibility and stability) of human skin are affected by the external stimuli, as well as the skin's structure and mechanical properties. Inspired by these tunable responses, three types of moisture-responsive wrinkle dynamics are achieved, for the first time, through a single film-substrate system. These dynamics include: (1) completely reversible wrinkles formation; (2) irreversible wrinkles formation I: the initially formed wrinkles can be permanently erased and never reappear; and (3) irreversible wrinkles formation II: once the wrinkles form, they can no longer be erased.

Massive aneurysm in a persistent sciatic artery.

Persistent sciatic artery (PSA) is an exceptionally rare embryological vascular anomaly with a reported incidence, based on angiographic series, of between 0.01 and 0.05%.

Femoral artery angiosarcoma presenting with distal embolization: report of a case.

Angiosarcoma of the femoral artery is an extremely rare malignant vascular tumor. The initial diagnosis is difficult to establish and distal metastasis can sometimes be the only presenting symptom. In this paper, we report the case of a 54-year-old man who presented with multiple painful necrotic lesions over the right foot secondary to an intimal angiosarcoma of the right common femoral artery.

Successful repair of a giant abdominal aortoiliac aneurysm in a Jehovah's Witness.

We report the case of a 76-year-old man of the Jehovah's Witness faith who had a giant abdominal aortoiliac aneurysm that was successfully operated on using an aortoiliac Y-graft bypass technique, without the use of stored allogenic blood. Cell saver technique and recombinant human erythropoietin (epoetin beta) were used during the perioperative period. The patient had good postoperative care with a multidisciplinary approach.

False aneurysm of the superior lateral geniculate artery following Total Knee Replacement.

Arterial complications following Total Knee Replacement are uncommon. We present a case of false aneurysm of the superior lateral geniculate artery presenting in the immediate postoperative period with continued bleeding from the surgical wound. This is the first case of false aneurysm of this vessel described following Total Knee Replacement.
