The potentials of and its rhizospheric, non-mycorrhizal fungi in biodegrading and bio-remediating hydrocarbon contaminated soil were investigated and Biodegradation study was done in two stages: preliminary study using hydrocarbon treated filter paper and with Mineral Salt Media (MSM) read on Spectrophotometer at two photo synthetically active wavelengths (530 nm and 620 nm) while rhizoremediation study was done in contaminated plot of land. Hydrocarbon utilization ability of the fungi and plant were confirmed using total petroleum hydrocarbon (TPH) analysis and gas chromatography mass spectroscopy (GC-MS). Results show differing rates of hydrocarbon utilization by isolated fungi. biodegradation study showed that and were best in degrading kerosene (78%), diesel (70%), spent engine oil (83%) and crude oil (77%) respectively. Rhizoremediation study using and show that remediation was enhanced to 72.15% as against 32.32% and 14% when only the plant or fungus is used respectively. Hydrocarbon accumulation by also decreased in the presence of the fungus. is shown in this study to enhance the germination, survival, growth and bioremediation efficiency of in polluted environment. The potentials of , a non-mycorrhizal fungi associated with in survival, growth and phytoremediation of petroleum hydrocarbon polluted soil by is highlighted in this study. and its associated fungi is shown to bio-remediate petroleum hydrocarbon through phyto-accumulation and rhizosphere effect.

Drainage from intentional extramacular holes after internal limiting membrane insertion to treat macular hole retinal detachment in highly myopic eyes.
Int Ophthalmol
January 2025
Department of Ophthalmology, Central Theater General Hospital, 627 Wuluo Road, Wuhan, 430070, China.
Purpose: The purpose is to evaluate the effect of drainage from intentional extramacular holes after internal limiting membrane insertion to treat macular hole retinal detachment (MHRD) in highly myopic eyes.
Methods: This study is a retrospective, observational, and comparative case series that included 25 consecutive highly myopic eyes with MHRD. All eyes underwent standard 23-gauge vitrectomy, inverted internal limiting membrane insertion into the macular hole, subretinal fluid drainage from an intentionally created extramacular retinal hole, and tamponade with either silicone oil (SO group, n = 13) or perfluoropropane (CF group, n = 12).
Polydopamine grafting polyether ether ketone to stabilize growth factor for efficient osteonecrosis repair.
Sci Rep
January 2025
Department of Bone Joint, Binzhou Medical University Hospital, No. 661 Huanghe 2nd Road, Binzhou, 256600, China.
This study examines the biocompatibility, osteogenic potential, and effectiveness of polyether ether ketone (PEEK) composites for treating osteonecrosis, seeking to establish a theoretical basis for clinical application. A range of PEEK composite materials, including sulfonated polyether ether ketone (SPEEK), polydopamine-sulfonated polyether ether ketone (SPEEK-PDA), bone-forming peptide-poly-dopamine-sulfonated polyether ether ketone (SPEEK-PDA-BFP), and vascular endothelial growth factor-poly-dopamine-sulfonated polyether ether ketone (SPEEK-PDA-VEGF), were constructed by concentrated sulfuric acid sulfonation, polydopamine modification and grafting of bioactive factors. The experiments involved adult male New Zealand rabbits aged 24-28 weeks and weighing 2.

Sterols and triterpene alcohols exist in free and esterified forms in edible oils. To date, only few studies have determined the content of free or esterified sterols and triterpene alcohols using gas chromatography-flame ionization detection (GC-FID). In this study, analytical conditions were optimized using free and esterified sterol standards.

This work is the first comprehensive survey of the Yangtze River, covering its origin to the estuary mouth. It focuses on the geographical and industrial factors influencing the distribution of polycyclic aromatic hydrocarbons (PAHs) in sediments, along with their contamination levels, sources, and ecological risks. The total concentrations of PAHs ranged from 2.
