The treatment of obese patients is a topic investigated by an increasing number of researchers. This study aimed to elucidate the possible inhibitory effect of tangeritin on the development and function of fat cells. 3T3-L1 fat cells were grown to confluence and subjected to different concentrations of tangeritin. The most effective tangeritin inhibition concentration was determined by the MTT assay. The treated cells were subjected to real-time reverse transcriptase PCR and western blot analysis, to detect changes in the CCAAT/enhancer binding protein (C/EBP)α, C/EBPβ, and peroxisome proliferator activated receptor (PPAR)γ expression levels. The MTT assay revealed that the fat cell growth was inhibited at a 20 ng/mL concentration of tangeritin. The results of real-time PCR revealed a significant decrease in the expression of C/EBPα, C/EBPβ, and PPARγ mRNA, following the treatment with tangeritin. Western blot analysis also presented similar results at a protein level. Therefore, we concluded that tangeritin inhibits adipogenesis via the down-regulation of C/EBPα, C/EBPβ, and PPARγ mRNA and protein expression in 3T3-L1 cells.

Rhinitis is a common comorbidity in patients with asthma. However, the frequency of underreported rhinitis in asthma is not known. In this study, we aimed to assess the characteristics of patients with self-reported asthma and no self-reported rhinitis, as well as the extent of the underreporting of rhinitis.

Genomic data on from the African continent are currently lacking, resulting in the region being under-represented in global analyses of infection (CDI) epidemiology. For the first time in Nigeria, we utilized whole-genome sequencing and phylogenetic tools to compare isolates from diarrhoeic human patients (=142), livestock (=38), poultry manure (=5) and dogs (=9) in the same geographic area (Makurdi, north-central Nigeria) and relate them to the global population. In addition, selected isolates were tested for antimicrobial susceptibility (=33) and characterized by PCR ribotyping (=53).

Do unions facilitate or hamper the effectiveness of high-performance work systems (HPWS)? Despite the long-standing interest among labor and human resource scholars on this matter, relevant studies are limited and dated. This research investigates whether and how the interplay between HPWS and unions affects both organizational performance and employee well-being outcomes. The authors argue while unions may attenuate the HPWS effects on organizational performance due to decreased performance climate, the overall impacts of unions are likely beneficial, as they facilitate cooperative climate that contributes to organizational performance and enhances employee well-being, which positively affects longer term organizational outcomes.

The composition conversion in block copolymer induced by external stimuli such as light and pH is an effective strategy to trigger the disassembly of vesicles experimentally. Based on this strategy, the disassembly behavior of the ABA triblock copolymer vesicle induced by the composition conversion from B block to C block was studied using Monte Carlo simulation. In this study, a part of the B block in the ABA triblock copolymer was converted to the new block C with weaker hydrophobicity, forming the ABCA tetrablock copolymer.
