owledge the high levels of the addictive substance nicotine. Of great concern is the lack of knowledge that college students have regarding nicotine based on their perceptions and the increasing use of these devices in those individuals with underlying respiratory conditions.
Disordered eating behaviors are prevalent among college-age individuals. Issues of control (e.g., perceptions of control; desire for control) are often salient for these individuals. Concerns regarding control can be exacerbated during transitions. The current study examined the extent to which disordered eating behaviors in college were predicted by locus of control, desire for control, and their interaction. We also explored whether these associations might be impacted by student life transitions (e.g., into/out of college).
A sample of 156 college students (72% women) was surveyed.
Both locus of and desire for control were predictive of disordered eating, but hypothesized moderations among locus of control, desire for control, and life transitions were primarily not supported.
Issues surrounding perceptions of control are important for disordered eating treatments or prevention programs, while more research is needed on the role life transitions may play in exacerbating risk.

We developed and optimised bio-analytical tools for detection of metabolites, aflatoxins and evaluated the effectiveness of the methods in co-infected maize tissues. Isolate KSM012 (atoxigenic) demonstrated no peaks and no blue fluorescence on HPLC and TLC plates respectively confirming non-toxicity. Selleckchem O6-Benzylguanine AFB1 and AFB2 were produced by Isolate KSM015 in addition to AFG1 and AFG2, which is an indication of possible SBG morphotype. The limits of quantification and detection ranged from 0.02 to 35.81 µg/mL and 0.01-6.8 µg/mL, respectively. The best mass spectrum with lowest noise was obtained at 100% ACN and sterile water spiked with 0.1% formic acid at a flow rate of 0.3 mL/min. The positive ion mode with electrospray ionisation application exhibited better fragmentation for mycotoxins. In total 17 metabolites were detected by targeted and formula mass. KDVI maize line exhibited high fungal colonisation in comparison to GAF4 at equal co-infection ratio 5050. AFB1 and AFG2 were remarkably higher in GAF4 in comparison to sensitive KDV1 (p ˂ 0.05). The detection limits, linearity and sensitivity showed the method developed was suitable for the determination of mycotoxin in comparisons to the guidelines of European Commission 657/EC 2002.
The unique demands placed on Division I student athletes (SAs) puts them at risk of experiencing poor sleep and increased psychological distress. Researchers have found that mindfulness improves well-being, directly and indirectly via sleep behaviors; however, it is not known if these relationships hold up within a sample of SAs. Thus, this study examined the indirect effect of mindfulness on psychological distress through sleep hygiene in SAs.
A sample of 269 Division I SAs were surveyed on their psychological distress, sleep hygiene, and mindfulness in 2018-2019.
Mindfulness directly and indirectly influenced psychological distress via sleep hygiene (
= -0.03,
 = 0.01, 95% CI [-0.05, -0.01]) such that increased mindfulness was associated with improved sleep hygiene and reduced distress.
The results show the impact of mindfulness on sleep hygiene and psychological distress. Training SAs in mindfulness might improve sleep behaviors and in turn well-being.

The purpose of this study was to establish the response rate of first-time college students to a vaccination records request, and to obtain student vaccination rates for selected vaccines.
Student health records for the fall 2018 cohort of first-time college students were reviewed.
Vaccination and response rates were compared based on sex, race/ethnicity, and home state.
There was a 66% response rate to the vaccination records request with no difference in response rate based on student demographics. Students exceeded most of the Healthy Campus 2020 vaccination targets. The human papillomavirus (HPV) and meningitis ACWY vaccines had the greatest room for improvement. Female students were significantly more likely to have a completed HPV vaccine series.
Records response rates may be improved by students accessing and reporting state vaccination information during a required orientation. Following (CDC) guidelines for vaccination success may improve vaccination rates for HPV and menACWY.
The purpomenACWY.Pepper cultivation in Israel has recently been constrained by two sympatric poleroviruses, Pepper vein yellows virus-2 (PeVYV-2) and Pepper whitefly-borne vein yellows virus (PeWBVYV) which are transmitted specifically by aphids and whiteflies, respectively. The interaction between PeVYV-2 and PeWBVYV inside the host plant and the insect vectors were investigated in this study. Our results show that PeVYV-2 and PeWBVYV compete against each other inside the host plant and also inside aphids. PeWBVYV was the weaker competitor inside the host plant with diminished transmission rates when inoculated simultaneously or successively after PeVYV-2 and could only be transmitted efficiently when inoculated first and then challenged by PeVYV-2. Successive inoculations of plants with viruliferous whiteflies with PeWBVYV, followed by viruliferous aphids with PeVYV-2 led to co-infection rate of 60%, however with severely reduced titers of PeWBVYV in the co-infected plants compared to singly infected ones. In contrast, PeVYV-2 was the weaker competitor inside the insect vector with reduced quantities of the acquired virus and reduced transmission rate by aphids when given prior acquisition on PeWBVYV. However, we also show that transmission efficiency of PeVYV-2 and PeWBVYV from co-infected plants by whiteflies and aphids remain comparable to that from singly-infected plants. This is probably due to the reduced titers of PeWBVYV inside co-infected plants causing lesser impact on transmission of PeVYV-2 by aphids and the stronger competitiveness of PeWBVYV inside whitefly. Competitive interactions between PeVYV-2 and PeWBVYV inside the host plant and insect vector can thus be beneficial for their co-existence.Pecan scab, caused by Venturia effusa, is the most economically damaging disease of pecan in the southeastern United States, and annual epidemics are most effectively managed through multiple fungicide applications. The fungicide applications can be the single greatest operating cost for commercial growers and the return on that investment is impacted by fungicide resistance. V. effusa produces multiple generations of conidia per season, exhibits substantial genetic diversity, overwinters as stromata in the tree, and is under immense selection from the applied fungicides, all of which lead to a high risk for developing fungicide resistance. Since the mid-1970s, resistance or reduced sensitivity has been observed in isolates of V. effusa to the methyl benzimidazole carbamates, demethylation inhibitors, quinone outside inhibitors, organotin compounds, and the guanidines. Over the last 10 years, several studies have been conducted that have improved both scab management and fungicide resistance management in V. effusa. The aim of this review is to summarize recent developments in our understanding of fungicide resistance in V. effusa in the context of scab management in southeastern pecan orchards. The history, modes of action, general use of the labeled fungicides, and mechanisms and stability of fungicide resistance in V. effusa are discussed; conclusions and future research priorities are also presented.Plant-parasitic nematodes are a costly burden of crop production. Ubiquitous in nature, phytoparasitic nematodes are associated with nearly every important agricultural crop and represent a significant constraint on global food security. Population genetics is a key discipline in plant nematology to understand aspects of the life strategies of these parasites, in particular their modes of reproduction, geographic origins, evolutionary histories, and dispersion abilities. Advances in high-throughput sequencing technologies have enabled a recent but active effort in genomic analyses of plant-parasitic nematodes. Such genomic approaches applied to multiple populations are providing new insights into the molecular and evolutionary processes that underpin the establishment of these nematodes and into a better understanding of the genetic and mechanistic basis of their pathogenicity and adaptation to their host plants. In this review, we attempt to update information about genome resources and genotyping techniques useful for nematologists who are thinking about initiating population genomics or genome sequencing projects. This review is intended also to foster the development of population genomics in plant-parasitic nematodes through highlighting recent publications that illustrate the potential for this approach to identify novel molecular markers or genes of interest and improve our knowledge of the genome variability, pathogenicity, and evolutionary potential of plant-parasitic nematodes.
