There was support for a three-way interaction with effortful control, but not working memory. As hypothesized, implicit cannabis attitudes were positively associated with cannabis use for adolescents with low levels of negative expectancies and low levels of effortful control.
 
  Findings suggest expecting negative outcomes of cannabis use is germane to dual process interactions between controlled and automatic processes. How to best operationalize self-regulation is an important consideration for future work.

Herein, we (i) quantified and visualised seasonal body image and its mechanisms, and (ii) identified individual predictors of seasonal body image. Sexual minority men (N = 823) residing in the Northern Hemisphere (n = 659) and Southern Hemisphere (n = 164) provided cross-sectional data about their experiences of body image phenomena in Spring, Summer, Autumn, and Winter. Most reported seasonal body image (∼70 %). As hypothesised, in Summer we observed peaks for body dissatisfaction alongside peaks in four proposed seasonal body image mechanisms pressure from media advertisements, pressure from peers on social media, the feeling that one's body is on public display, and appearance comparisons. In Winter, these phenomena were weakest.  https://www.selleckchem.com/products/VX-809.html  Effect sizes ranged from small to large (rs = .07-.50) with an average effect size of medium (.38). Seasonal body image was stronger for individuals with greater muscularity dissatisfaction and body fat dissatisfaction, and for higher body-weight and younger individuals. Future research will visualise seasonal body image using a multi-country Twitter database containing several billion tweets spanning multiple calendar years.In this research, a core-shell type pH-responsive poly-l-glutamic acid embedded mesoporous bioactive glass nanospheres (MBAG/PLGA) was designed via aminosilane functionalization of MBAG using 3-aminopropyltriethoxysilane (APTES). The formation of MBAG/PLGA was well dispersed in an aqueous medium and demonstrated high drug loading efficacy and enhanced drug delivery rate. Daunomycin (DAN) was considered as a model chemotherapeutic drug for loading and release study. The cumulative in vitro release of DAN from DAN loaded MBAG/PLGA (MBAG/PLGA@DAN) was observed to be pH-dependent and, the DAN release rate was much higher at pH ∼ 5.5 compared to pH at 7.4. The modified Kirby-Bauer microbial assay results showed that the MBAG is a potential antimicrobial agent and susceptibility for Gram-negative bacteria is observed to be much higher than Gram-positive ones. Advanced characterization studies such as SEM coupled with EDX, HRTEM, FTIR, XPS, TGA, XRD, and BET analysis were performed to support the findings of this research. Overall, these results demonstrated that MBAG/PLGA is a promising candidate for a pH-responsive localized drug delivery system in bioconjugate science.Metallic corrosion is a recurrent and costly problem to almost every industry; therefore, prevention strategies might be well-defined on a case-by-case basis. Commonly, cathodic protection (CP) is the world's most widely-adopted technique to guarantee the integrity of buried or submerged structures from corrosion. However, as current potential values are dependent on metal-structure and environmental features, the target shall be well-identified; otherwise, the intended effect will not be reached. In seawater, a protective current potential of -800 mVAg/AgCl is recommended by technical standards, while a more negative potential (-900 mVAg/AgCl) is the suggested criterion for the control of corrosion induced by sulfate-reducing bacteria (SRB), even though without proper scientific support. Thus, this study focused on evaluating the efficiency of different cathodic protection potentials (-800, -900 and, -1000 mVAg/AgCl) on inhibiting SRB-mediated corrosion of AISI 1020 steel. Both unprotected and impressed current cathodically protected steel specimens were exposed to indigenous microorganisms in seawater for 7 days. The Most Probable Number (MPN) enumeration of sessile aerobic heterotrophic bacteria, acid-producing bacteria and, sulfate-reducing bacteria was performed at the beginning and at the end of the assays. Also, the reducing activity of hydrogenase-positive SRB strains was measured. Although the microbial colonization was greater on unprotected steel surfaces than on the cathodically protected ones, biofilm quantification of CP specimens did not show important differences regardless of the potential. However, hydrogenase-positive SRB counts increased with the reduction of CP potential value, promoting an increase in the number and depth of pits on specimens protected at -1000 mVAg/AgCl when compared with those protected at -800 mVAg/AgCl and unprotected ones.Currently, implant-related bone infection characterized by aggravated infection-induced inflammatory responses and osteolysis, remains a severe challenge in orthopedic surgery, especially in patients with osteoporosis. Attempts to control such responses using biomaterials with combined immunomodulatory and anti-bacterial properties may provide novel strategies. Herein, DJK-5, a class of host defense peptides (HDPs) with established antimicrobial and immunomodulatory functions, was introduced into porous Ti alloy. Our results indicated that the DJK-5 immobilized surfaces showed intrinsically multifunctional properties, including antibacterial ability, anti-inflammation, biocompatibility and osteolysis-inhibiting properties. The results demonstrated that the antibacterial efficiency of DJK-5 functionalized surfaces was over 90 % for both Gram-positive and Gram-negative bacteria. Specifically, DJK-5 functionalized samples also possessed the excellent anti-bacterial activity against a mixture of bacterial strains, including S.
