[Research Progress in the Association Between Sarcopenic Obesity and Cancer].

As the global prevalence of obesity and the elderly population continues to increase,the incidence of sarcopenic obesity is also on the rise and becoming a global public health concern.Sarcopenic obesity not only increases the incidence of cancer,but is also associated with poor clinical outcomes in various cancers,such as surgical complications,increased risk of death,and possibly even an impact on chemotherapy as well.Therefore,sarcopenic obesity is emerging as an important indicator of prognosis in cancer patients.

[Mechanism of Impaired Cognitive Function in Patients with Chronic Kidney Disease].

Each stage of chronic kidney disease has a high risk of cognitive dysfunction.The decline of cognitive function will affect the daily life and treatment compliance of the patients with chronic kidney disease and increase the patients' risk of death and public health burden,which has aroused widespread concern.However,the specific mechanism of cognitive impairment in the patients with chronic kidney disease remains unclear.

Ultra-bright alkylated graphene quantum dots.

Highly efficient and stable photoluminescence (PL) are urgently desired for graphene quantum dots (GQDs) to facilitate their prospective applications as optical materials. Here, we report the facile and straightforward synthesis of alkylated graphene quantum dots (AGQDs) via the solvothermal reaction of propagatively alkylated graphene sheets (PAGenes). In contrast to most GQDs reported so far, the synthesized AGQDs process pH-independent and ultra-bright PL with a relative quantum yield of up to 65%.

Facile and straightforward synthesis of superparamagnetic reduced graphene oxide-Fe3O4 hybrid composite by a solvothermal reaction.

A superparamagnetic reduced graphene oxide-Fe(3)O(4) hybrid composite (rGO-Fe(3)O(4)) was prepared via a facile and straightforward method through the solvothermal reaction of iron (III) acetylacetonate (Fe(acac)(3)) and graphene oxide (GO) in ethylenediamine (EDA) and water. By this method, chemical reduction of GO as well as the formation of Fe(3)O(4) nanoparticles (NPs) can be achieved in one step. The Fe(3)O(4) NPs are firmly deposited on the surfaces of rGO, avoiding their reassembly to graphite.
