This work reveals a wider set of genes that contribute to fosfomycin susceptibility, including core sugar metabolism genes and two systems involved in phosphate uptake and metabolism previously unrecognized as having a role in fosfomycin susceptibility.

  We validated an aging mindset measure that captures beliefs about the process of aging. Specifically, we introduce a brief 4-item and an extended 10-item measure assessing (non)essentialist beliefs about aging.
 
  We report findings from one longitudinal and one cross-cultural study, including young, middle-aged, and older adults between 18 and 88 years. The studies established (retest) reliability and measurement invariance as well as convergent and discriminant validity of the measures.
 
  First, in a longitudinal study (N = 124, 50- 84 years) including 4 measurement occasions, we showed that the 4-item scale assessing (non)essentialist beliefs about aging has good retest-reliability and convergent as well as discriminant validity (e.g., awareness of age-related change, AARC). Second, in a large cross-cultural sample (N = 1,080, 18-82 years) of participants in the US and Germany, we established an extended 10-item measure of (non)essentialist beliefs about aging, providing support for a two-factor structure as well as measurement invariance across samples within and across countries (US and Germany), age groups (young, middle-aged, and older adults), as well as across men and women.
 
  Our results highlight the importance of distinguishing between fixed versus malleable aging beliefs in research on aging and lifespan development.

  The mental and physical health profile of autistic people has been studied in adolescence and adulthood, with elevated rates of most conditions being reported. However, this has been little studied taking a dimensional approach to autistic traits, and in older age.
 
  A total of 20,220 adults aged 50-81 years from the PROTECT study reported whether they experienced persistent socio-communicative traits characteristic of autism. Approximately 1%, 276 individuals, were identified as endorsing elevated autistic traits in childhood and currently, henceforth the 'Autism Spectrum Trait' (AST) group. An age and gender matched comparison group was formed of 10,495 individuals who did not endorse any autistic behavioral traits, henceforth the 'Control Older Adults' (COA) group. Differences between AST and COA groups were explored in self-reported psychiatric diagnoses, self-reported symptoms of current depression and anxiety, and self-reported physical health diagnoses. Associations were also examined between autistidults with elevated autistic traits may be at greater risk of poorer mental, but not physical, health in later life. Future studies should incorporate polygenic scores to elucidate the possible genetic links between propensity to autism/high autistic traits and to psychiatric conditions, and to explore whether those with elevated autistic traits experience particular barriers to mental health care.
  Controversy exists regarding if and how body mass index (BMI) impacts antimüllerian hormone (AMH) in women with and without polycystic ovary syndrome (PCOS). Understanding the BMI-AMH relationship has critical implications for clinical interpretation of laboratory values and could illuminate underlying ovarian physiology.
 
  To test the hypotheses that (1) BMI is associated with reduced AMH in PCOS and ovulatory controls (OVAs) and (2) the reduction in AMH is not accounted for by dilutional effects.
 
  Multicenter cohort.
 
  Women aged 25 to 40 years from 2 clinical populations 640 with PCOS, 921 women as OVAs.
 
  Ovarian reserve indices AMH, antral follicle count (AFC), and AMH to AFC ratio (AMH/AFC) as a marker of per-follicle AMH production.
 
  In both cohorts, increasing BMI and waist circumference were associated with reductions in AMH and AMH/AFC, after adjusting for age, race, smoking, and site in multivariate regression models. Increasing BMI was associated with reduced AFC in PCOS but not OVAs. Body surface area (BSA), which unlike BMI is strongly proportional to plasma volume, was added to investigate a potential dilutive effect of body size on AMH concentrations. After controlling for BSA, BMI retained independent associations with AMH in both cohorts; BSA no longer associated with AMH.
 
  In an adjusted analysis, BMI, but not BSA, was associated with reduced AMH; these data do not support a role for hemodilution in mediating the relationship between increased body size and reduced AMH.  https://www.selleckchem.com/products/bmh-21.html  Decreased AMH production by the follicle unit may be responsible for reduced AMH with increasing BMI.

In this work, four chalcones with modifications in their ligands were synthesized from the natural product 2-hydroxy-3,4,6-trimethoxyacetophenone, characterized by nuclear magnetic resonance (NMR) and infrared spectroscopy, and tested in bacterial models to investigate the direct and modifiers effects of the antibiotic activity of these four novel chalcones. The tests followed the broth microdilution methodology to obtain the Minimum Inhibitory Concentration (MIC). The MIC/8 of the products were used in the resistance reversion test. The chalcone 2 showed the best result in terms of direct activity, with MIC 645 μg/mL for Staphylococcus aureus and 812 μg/mL for Escherichia coli. While, for the bacterial resistance reversal test, the chalcones presented several synergistic interactions, being that chalcone 4 had the best interaction with the tested antibiotics. It was found that the type of ligand, as well as its position in the ring, interferes in the modulation of the antibiotic activity.
