We report a microfluidic approach for one-step fabrication of polyelectrolyte microcapsules in aqueous conditions. Using two immiscible aqueous polymer solutions, we generate transient water-in-water-in-water double emulsion droplets and use them as templates to fabricate polyelectrolyte microcapsules. The capsule shell is formed by the complexation of oppositely charged polyelectrolytes at the...

Restricted water diffusion has been used to distinguish pyogenic abscess from other rim-enhancing brain masses; however diffusion-weighted imaging of cerebral infection before capsule formation has rarely been described. We report a case of fungal cerebritis in which water diffusion was more restricted than that of normal contralateral brain and the measured diffusion coefficient was in the ran...

In this work, tunicate cellulose nanocrystals (tCNCs) were extracted from the by bleaching and acid hydrolysis. They used as filler in preparation of sodium alginate-based enteric capsules. The addition tCNCs with a high aspect ratio (65) rendered capsule excellent physical properties. Compared control sample, when 10% (wt), water contact angle was enhanced 46.0%, opacity increased 356.8%, maxi...

(H(2)O)(32)-shell structure constructed by two unique water molecules in high symmetry crystal leads to good water-solubility of the obtained compound 1.

would alter the angle of the pulled papilla. With minor adjustments, cannulation can be achieved. In conclusion, when a hooded major papilla is encountered at ERCP, traction of the papilla by the use of forceps may be useful. Application of clips during ERCP: a new anchoring method for redundant Kerckring's fold covering the duodenal papilla. Capsule endoscopy has quickly become a cornerstone f...

A fuel-free autonomous self-propelled motor is illustrated. The motor is powered by the chemistry of calcium carbide and utilising water as a co-reactant, through a polymer encapsulation strategy. Expulsion of acetylene bubbles powers the capsule motor. This is an important step, going beyond the toxic hydrogen peroxide fuel used normally, to find alternative propellants for self-propelled mach...

purpose: to evaluate the effect of limited dissection of tenon sheath on the outcome of horizontal strabismus surgery. methods: patients with horizontal strabismus, aged between six and 50 years, were enrolled in this non-randomized study. patients with pattern and vertical strabismus or a history of strabismus surgery were excluded. the strabismus surgeries consisted of bimedial recession (bmr...

The interaction of a tetracationic calixarene (TAC4) with dianionic guest (BS) in water was studied with NMR, nano-ITC and ESI-MS experiments; the convergent evidence provided by these different techniques shows that the addition of a suitable guest molecule triggers the formation of a homodimeric capsule in aqueous neutral solution.

The organic co-solvent induced denaturation of a series of capsular complexes formed between trioxolane guests and a water-soluble deep-cavity cavitand was examined. The results obtained demonstrate a wide range of denaturation properties, and suggest the important factors governing capsule stability.
