Furthermore, the transfer pathway between the electron and hole was also shortened, and the recombination of the electron and hole was inhibited. According to the results, an optimal hydrogen evolution rate of 31.7 mol h-1 g-1 was achieved by U-C3N4, which is 5.1 times higher as compared to that achieved by pristine g-C3N4 (6.26 mol h-1 g-1). For the photocatalytic degradation of rhodamine B, the reaction rate constant of U-C3N4 (11.3 × 10-2 min-1) is about 5.5 times that of g-C3N4 (2.07 × 10-2 min-1). Furthermore, the uracil-doped catalyst was also able to demonstrate good stability after five successive runs.We describe a new functional group metathesis between aryl nitriles and aryl thioethers. The catalytic system nickel/dcype is essential to achieve this fully reversible transformation in good to excellent yields. Furthermore, the cyanide- and thiol-free reaction shows high functional group tolerance and great efficiency for the late-stage derivatization of commercial molecules. Finally, synthetic applications demonstrate its versatility and utility in multistep synthesis.Hydrogels as a wound dressing, integrated with ultrastretchability, rapid self-healing, and excellent antimicrobial activity, are in high demand, particularly for joint skin wound healing. Herein, a multifunctional and ductile composite hydrogel was developed using poly(vinyl alcohol) (PVA)-borax gel as a matrix that was synergized or dual-reinforced with dopamine-grafted oxidized carboxymethyl cellulose (OCMC-DA) and cellulose nanofibers (CNF). Moreover, neomycin (NEO), an aminoglycoside antibiotic with multifunctional groups, was incorporated into the hydrogel network as both an antibacterial agent and a cross-linker. The dynamic reversible borate ester linkages and hydrogen bonds between OCMC-DA, PVA, and CNF, along with dynamic cross-linking imine linkages between NEO and OCMC-DA, endowed the hydrogel with excellent self-healing ability and stretchability (3300%). check details The as-reinforced networks enhanced the mechanical properties of hydrogels significantly. More remarkably, the composite hydrogel with improved biodegradability and biocompatibility is pH-responsive and effective against a broad spectrum of bacteria, which is attributed to the controllable release of NEO for steady availability of the antibiotic on the wound location. Overall, the antimicrobial hydrogel with rapid self-healing and reliable mechanical properties holds significant promise as dressing material for wound healing.Aim Facial aesthetics is at present a concept intricately linked to the degree of self-esteem. Unwanted submental fat (SMF) leads to an unattractive submental profile. Sodium deoxicolate (ATX) -101 is the only injectable drug approved to decrease submental fat of moderate to severe intensity. Methods We carried out a bibliographic review in PubMed using the key words deoxycholic acid, ATX-101, and submental fat. Only complete articles published between 2009 and 2019, and focused on submental fat were reviewed, excluding those articles relating to that spoke of deoxycholate in the treatment of fat in other locations or in which deoxycholate was associated with other drugs. Results In several phase III clinical trials, injection of 2 mg/cm2 deoxycholic acid in SMF has reduced moderate-severe fullness compared to the placebo group. These results were maintained in most cases during a long follow-up period. Injections of deoxycholic acid are generally well tolerated, with limited adverse effects in the treatment area, with a mild and complete resolution without sequelae. However, not all patients with SMF are suitable for deoxycholic acid therapy, and therefore a proper selection is very important to achieve the desired aesthetic results. Conclusion Deoxycholic acid injections are effective and are a generally well-tolerated, minimally invasive option for the treatment of moderate to severe intensity SMF in selected adults.Aim Scrotal bruises are quite fre
