The stereotype content model (SCM) proposes potentially universal principles of societal stereotypes and their relation to social structure. Here, the SCM reveals theoretically grounded, cross‐cultural, cross‐groups similarities one difference across 10 non‐US nations. Seven European (individualist) three East Asian (collectivist) nations ( N =1,028) support hypothesized cross‐cultural similarities: (a) perceived warmth competence reliably differentiate group stereotypes; (b) many out‐groups...
Abstract Reliable electroencephalography (EEG) signatures of transitions between consciousness and unconsciousness under anaesthesia have not yet been identified. Herein we examined network changes using graph theoretical analysis high-density EEG during patient-titrated propofol-induced sedation. Responsiveness was used as a surrogate for consciousness. We divided the data into five states: baseline, transition unresponsiveness, responsiveness, recovery. Power spectral showed that delta...
The authors argue that complementary hostile and benevolent components of sexism exist across cultures.Male dominance creates (HS), but men's dependence on women fosters (BS)--subjectively positive attitudes put a pedestal reinforce their subordination.Research with 15,000 men in 19 nations showed (a) HS BS are coherent constructs correlate positively nations, (b) predicts the ascription negative traits to women, (c) relative men, more likely reject than BS, especially when overall levels...
Curcumin has diverse therapeutic effects, such as anti-inflammatory, anti-oxidant, anti-cancer, and antimicrobial activities. The vanilloid moiety of curcumin is considered important for activation the transient receptor potential 1 (TRPV1), which plays an role in nociception. However, very little known about effects on In present study, we investigated whether anti-nociceptive are mediated via TRPV1 by using nociceptive behavioral studies vitro whole-cell patch-clamp recordings trigeminal...
We developed three-dimensional electrospun silk fibroin (ESF) scaffolds with controllable pore size. The purpose of this study was to evaluate ESF pores (P-ESF) for bone regeneration via in vitro and vivo studies, a comparison commercially available porous polylactic acid (PLA) scaffold. P-ESF supported significantly higher proliferation alkaline phosphatase activity osteoblasts than PLA (p < 0.05). Moreover, expression levels activated adhesion-related proteins, including focal adhesion...
Some plant flavonoids in the form of whole extracts have been used topically for skin inflammatory disorders. Since matrix metalloproteinase-1 (MMP-1, collagenase-1) plays an important role unbalanced turn-over or rapid breakdown collagen molecules human inflamed/UV-irradiated skin, effects natural on MMP-1 activity and expression were studied to establish therapeutic potential. Against recombinant MMP-1, flavonols such as quercetin kaempferol strong inhibitors with IC50 values 39.6 43.7 μM,...
In the search for a new thermogelling biomaterial, we are reporting poly(ethylene glycol)−poly(trimethylene carbonate) (PEG−PTMC) diblock copolymers. The PEG−PTMC (550−2750) copolymer aqueous solutions (>25 wt %) underwent sol-to-gel-to-syneresis (macroscopic phase separation between polymer and water) transition as temperature increased. sol-to-gel could be controlled in range of 20−75 °C by varying concentration water, molecular weight, composition polymer. 13C NMR spectra, transmission...
Recent advances in automated cell counters enable us to count cells more easily with consistency. However, the wide use of traditional vital dye trypan blue (TB) raises environmental and health concerns due its potential teratogenic effects. To avoid this chemical hazard, it is importance introduce an alternative non-hazardous that compatible counters. Erythrosin B (EB) a impermeable biological membranes used as food additive. Similarly TB, EB stains only nonviable disintegrated membranes....
We study the synchronization phenomena in a system of globally coupled oscillators with time delay coupling. The self-consistency equations for order parameter are derived, which depend explicitly on amount delay. Analysis these reveals that general exhibits discontinuous transitions addition to usual continuous transition, between incoherent state and multitude coherent states different frequencies. In particular, phase diagram is obtained plane coupling strength time, ubiquity...
A paucity of reports exist on the use botulinum toxin type injections as an alternative noninvasive treatment for masseteric hypertrophy.To evaluate effects hypertrophy using computed tomography.Percutaneous intramuscular 30 U per side was carried out in 11 subjects with hypertrophy. The changes muscle volume before and 12 weeks after injection were evaluated tomography. lower facial contours photographs excellent, good, fair, no changes.Nine showed a mean reduction approximately 22% volume....
Local anesthetics have been generally accepted as being safe. However, recent clinical trials and basic studies provided strong evidence for the neurotoxicity of local anesthetics, especially through apoptosis. We hypothesized that cause neural complications Schwann cell Among tested on line, RT4-D6P2T, bupivacaine significantly induced death, measured by methyl tetrazolium (MTT) assay, in a dose- (LD 50 = 476 μM) time-dependent manner. The bupivacaine-induced generation reactive oxygen...
Mutations in Cu,Zn superoxide dismutase (SOD1) are associated with familial amyotrophic lateral sclerosis (ALS). Mutant SOD1 causes a complex array of pathological events, through toxic gain function mechanisms, leading to selective motor neuron degeneration. Mitochondrial dysfunction is among the well established effects mutant SOD1, but its mechanisms just starting be elucidated. A portion localized mitochondria, where it accumulates mostly on outer membrane and inside intermembrane space...
Amyotrophic lateral sclerosis is a devastating neurodegenerative disorder that more prevalent in males than females. A similar gender difference has been reported some strains of transgenic mouse models familial amyotrophic harbouring the G93A mutation CuZn superoxide dismutase. Mitochondrial damage caused by pathological alterations Ca(2+) accumulation frequently involved diseases, including dismutase-related sclerosis, but its association with not firmly established. In this study, we...
