The wood-rot basidiomycete has been chemically investigated. Comparative analyses of the natural fruiting body, artificially cultivated fruiting bodies, and mycelial cultures resulted in the isolation, in total, of 13 new highly modified lanostanes, ganocolossusins A-H (-) and ganodermalactones T-X (-), together with 23 known compounds (-). There were significant overlaps of the same compounds among the three different states of the fungal materials. Ganocolossusin D () displayed the most potent antimalarial activity against K1 (multi-drug-resistant strain) with an IC value of 2.4 μM, while it was noncytotoxic to Vero cells at 50 μg/mL.

Modified Green-Ampt model for infiltration analysis in loess area and its parameter determination and verification.

Water infiltration into soil is important in geotechnical engineering. The classical Green-Ampt (GA) infiltration model is widely used in soil infiltration due to its physical significance, but it ignores the actual unsaturated layer in the infiltration process and has some deficiencies. Thus, the present study established a modified GA infiltration model (MLGA model) using Darcy's infiltration law and continuity equation to fully consider the variation characteristics of the soil water profile in the infiltration process.

Background: Anatomic total shoulder arthroplasty are highly successful procedures for treatment of glenohumeral arthritis to reduce pain, improve range of motion, and overall quality of life. However, the long-term survivorship of the implant systems is less widely documented in the existing literature. The purpose of this study was to establish the long-term patient outcomes and identify factors influencing the postoperative implant survivorship of total anatomic shoulder arthroplasty devices/procedures utilizing the short-stemmed prosthesis and hybrid glenoid components of the Comprehensive Shoulder System (Zimmer Biomet, Warsaw, IN, USA) at an average of ten years.

Graphene oxide (GO) is an amphiphilic and versatile graphene-based nanomaterial that is extremely promising for targeted drug delivery, which aims to administer drugs in a spatially and temporally controlled manner. A typical GO nanocarrier features a polyethylene glycol coating and conjugation to an active targeting ligand. However, it is challenging to accurately model GO dots, because of their intrinsically complex and not unique structure.

Copper-containing industrial wastewater, characterized by strong acidity, high ionic strength, and various competing metals, presents significant challenges for Cu(II) recovery. To address these issues, an electric field-enhanced ultrafiltration process was developed, assisted with a functional polyelectrolyte with high selectivity for Cu(II). The polyelectrolyte, termed PPEI, was synthesized by grafting picolyl groups onto polyethyleneimine (PEI), enhancing its affinity for Cu(II).

As an essential B vitamin, folate participates in one‑carbon metabolism. The 5-methyltetrahydrofolate (5-MTHF) avoids the drawbacks associated with folic acid and native folylpolyglutamate folate in food, thereby emerging as a superior alternative to folate supplement. To enhance the stability and digestibility of 5-MTHF, nanoliposome (NL) was modified using a layer-by-layer self-assembly method with chitosan (CH) and pectin (P).
