Reversible Nanocomposite by Programming Amorphous Polymer Conformation Under Nanoconfinement.

Nanoconfinements are utilized to program how polymers entangle and disentangle as chain clusters to engineer pseudo bonds with tunable strength, multivalency, and directionality. When amorphous polymers are grafted to nanoparticles that are one magnitude larger in size than individual polymers, programming grafted chain conformations can "synthesize" high-performance nanocomposites with moduli of ≈25GPa and a circular lifecycle without forming and/or breaking chemical bonds. These nanocomposites dissipate external stresses by disentangling and stretching grafted polymers up to ≈98% of their contour length, analogous to that of folded proteins; use both polymers and nanoparticles for load bearing; and exhibit a non-linear dependence on composition throughout the microscopic, nanoscopic, and single-particle levels.

Outcome following pylorus resecting pancreaticoduodenectomy versus classical Whipple's pancreaticoduodenectomy: a randomised controlled trial.

Objective: To compare pylorus resecting pancreaticoduodenectomy (PRPD) with classical pancreaticoduodenectomy (classical PD) in terms of short term outcomes.

Background: There is some evidence that Pylorus resecting PD (PRPD) is associated with lesser incidence of DGE when compared to pylorus preserving PD (PPPD). However, no study has previously compared PRPD with classical PD.

Patterns of neuronal synchrony in higher-order networks.

Synchrony in neuronal networks is crucial for cognitive functions, motor coordination, and various neurological disorders. While traditional research has focused on pairwise interactions between neurons, recent studies highlight the importance of higher-order interactions involving multiple neurons. Both types of interactions lead to complex synchronous spatiotemporal patterns, including the fascinating phenomenon of chimera states, where synchronized and desynchronized neuronal activity coexist.

Synthesis of acenaphthylene-fused heteroarenes and polyoxygenated benzo[]fluoranthenes via a Pd-catalyzed Suzuki-Miyaura/C-H arylation cascade.

Acenaphthylene-fused heteroarenes with a variety of five- and six-membered heterocycles such as thiophene, furan, benzofuran, pyrazole, pyridine and pyrimidine were synthesized via an efficient Pd-catalyzed reaction cascade in good to high yields (45-90%). This cascade involves an initial Suzuki-Miyaura cross-coupling reaction between 1,8-dihalonaphthalenes and heteroarylboronic acids or esters, followed by an intramolecular C-H arylation under the same conditions to yield the final heterocyclic fluoranthene analogues. The method was further employed to access polyoxygenated benzo[]fluoranthenes, which are all structurally relevant to benzo[]fluoranthene-based fungal natural products.

Primary cutaneous melioidosis - A rare case needing intensive care unit admission.

Background: Melioidosis cases are increasing in Southeast Asia, posing a significant challenge owing to the rising number of diabetic and immune compromised patients. Pneumonia is the most common presentation of melioidosis, while cutaneous melioidosis is rare.

Objectives: We report a case of primary cutaneous melioidosis (PCM) that eventually required intensive care unit (ICU) management.
