Fe-N-C with atomically dispersed Fe single atoms is the most promising candidate to replace platinum for the oxygen reduction reaction (ORR) in fuel cells. However, the conventional synthesis procedures require quantities solvents and metal precursors, sluggish adsorption process, and tedious washing, resulting in limited metal doping and uneconomical for large-scale production. For the first time, FeO is adopted as the Fe precursor to derive abundant single Fe atoms dispersed on carbon surfaces. Read More

Objective: Differential diagnosis of idiopathic pulmonary fibrosis (IPF) is important among fibrotic interstitial lung diseases (ILD). This study aimed to evaluate the rate of IPF in patients with fibrotic ILD and to determine the clinical-laboratory features of patients with and without IPF that would provide the differential diagnosis of IPF.

Material And Methods: The study included the patients with the usual interstitial pneumonia (UIP) pattern or possible UIP pattern on thorax high-resolution computed tomography, and/or UIP pattern, probable UIP or possible UIP pattern at lung biopsy according to the 2011 ATS/ERS/JRS/ALAT guidelines.

During postharvest life, broccoli suffers from floret yellowing confining its economic and nutritional value. The objective of the present study was to explore the mechanisms employed by phytosulfokine α (PSKα) at 150 nM for delaying floret yellowing in broccoli during storage at 4°C for 28 days. Our results showed that the higher endogenous accumulation of hydrogen sulfide (HS) resulting from the higher gene expression and activities of l-cysteine desulfhydrase () and d-cysteine desulfhydrase () in broccoli floret treated with 150 nM PSKα may serve as an endogenous signaling molecule for delaying senescence.

Background: Sexual minorities, such as men who have sex with men (MSM), are dis-proportionately impacted by HIV/AIDS compared to heterosexual men . The increased prevalence of HIV/AIDs among this group of individuals is associated with increased participation in HIV-related risk behavior, such as multiple sexual partnerships and in-jection drug use. However, very little is known about the prevalence of HIV and the risk behaviors related to HIV infection among MSM in Iran. Read More
