Harmless and efficient nickel enrichment from nickel-containing waste slag using vitrification technology.

With the growing demand for nickel in the stainless steel and battery industries, conventional methods of extracting nickel from ores face challenges such as high production costs and environmental concerns. This study proposes a new process for the recovery of nickel metal and the production of nickel-iron alloys from nickel-bearing scrap. The reduction rates of nickel and iron oxides were investigated by optimizing the roasting temperature, time, and C/O ratio, and the process was optimized using response surface methodology (RSM).

Select microbial metabolites in the small intestinal lumen regulates vagal activity via receptor-mediated signaling.

The vagus nerve is proposed to enable communication between the gut microbiome and the brain, but activity-based evidence is lacking. We find that mice reared germ-free exhibit decreased vagal tone relative to colonized controls, which is reversed via microbiota restoration. Perfusing antibiotics into the small intestines of conventional mice, but not germ-free mice, acutely decreases vagal activity which is restored upon re-perfusion with intestinal filtrates from conventional, but not germ-free, mice.

Three new species of (Amphisphaeriales, Apiosporaceae) in China.

China is located in eastern Asia and has a large quantity and rich variety of bamboo resources. Bamboo resources also contain various fungal species such as The genus is commonly used as plant pathogens, endophytes, and saprophytes, which are widely present in various host ranges around the world. The discovery of metabolites has been proven to play an important role in the pharmaceutical industry.

Long non-coding RNA NRIR inhibits osteogenesis in peri-implantitis by promoting NLRP3 inflammasome-mediated macrophage pyroptosis.

Background: Peri-implantitis is an inflammatory bone disease that seriously affects the health of dental implants. Pyroptosis plays an important role in peri-implantitis and inhibition of pyroptosis may point out a new direction for treating the disease. The long non-coding RNA Negative Regulator of Interferon Response (lncRNA NRIR) is closely related to peri-implantitis and may be involved in the process of pyroptosis.

Fu Tu Sheng Jin Rehabilitation Formula Mitigate Airway Inflammation, Mucus Secretion and Immune Dysfunction Induced by SARS-CoV-2 Spike Protein.

Objective: To evaluate the effects of Fu Tu Sheng Jin Rehabilitation Formula (FTSJRF) on airway inflammation, mucus secretion, and immunoreaction in a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein-induced mouse model.

Methods: Forty-two mice were randomly divided into seven groups: normal, D1, D3, D10, D10H, D10M and D10L, according to the days of modeling and different dosages of FTSJRF. D1, D3, D10, D10H, D10M and D10L group mice were intratracheally administered with 15 µg SARS-CoV-2 spike protein; mice in the D10H, D10M, and D10L groups were intragastrically administered FTSJRF (46, 23 and 11.
