Magnetic biochar derived from agricultural biomass has been recognized as a cost-effective biochar sorbent for phosphate removal. This study evaluated the use of novel Fe/Mg-biochar nanocomposites (WBC1x), prepared by impregnating ground walnut shell in a solution with a different molar ratio of Fe2+ to Mg2+, then pyrolyzing slowly, at a…[Read more]

Instead, the alterations switch the oligomeric state from tetramer to trimer. To improve the robustness of designed homotetramers, additional sequences based on CC-Tet were produced and characterized in solution and by X-ray crystallography. Of these updated sequences, one is robust to truncation and to changes in surface electrostatics; we call…[Read more]

Sleep spindles benefit declarative memory consolidation and are considered to be a biological marker for general cognitive abilities. However, the impact of sexual hormones and hormonal oral contraceptives (OCs) on these relationships are less clear. Thus, we here investigated the influence of endogenous progesterone levels of naturally cycling…[Read more]

Protein analysis by desorption electrospray ionization mass spectrometry (DESI-MS) is limited and often accompanied by a mass-dependent loss in sensitivity as protein molecular weight increases. Previously, incomplete dissolution was identified as a potential contributing factor to this limitation for larger proteins. Here, we developed a unique…[Read more]

and complex correlation among body composition parameters, grip strength, and gait speed in patients with operable gastric cancer. A comprehensive analysis of these parameters has significant predictive value for postoperative complications and survival.

Jianqu, a classical formula of traditional Chinese medicine, is used clinically to treat…[Read more]
