Barbara G. Pickard - Queen of Plant Electrophysiology

ABSTRACT Barbara Gillespie Pickard (1936–2019) studied plant electrophysiology and mechanosensory biology for more than 50 y. Her first papers on the roles of auxin in plant tropisms were coauthored with Kenneth V. Thimann. Later, she studied plant electrophysiology. She made it clear that plant action potentials are not a peculiar feature of so-called sensitive plants, but that all plants exhibit these fast electric signals. Barbara Gillespie Pickard proposed a neuronal model for the spreading of electric signals induced by mechanical stimuli across plant tissues. In later years, she studied the stretch-activated plasma membrane channels of plants and formulated the plasma-membrane control center model. Barbara Pickard summarized all her findings in a new model of phyllotaxis involving waves of auxin fluxes and mechano-sensory signaling.
Exploring Condom Use Behaviors Among African American Adolescent Boys in the Deep South

Risky sexual behaviors among adolescents can increase adverse outcomes including unplanned pregnancy or contraction or transmission of disease. Adolescents who engage in risky sexual activities are at increased risk for adverse health and social outcomes compared to those who do not engage. Despite declines in adolescent pregnancy and birth rates, the diagnosis of sexually transmitted infections (STIs) is steadily increasing among adolescents. Moreover, African American adolescent boys in the United States, specifically in the southeastern region are disproportionally at greater risk for STIs, and STI diagnosis within this population has increased over time, compared to their white counterparts. This study sought to identify factors associated with condom use among adolescent boys in the Deep South. Using data from the Mobile Youth Survey, a longitudinal adolescent community-based survey, this study assessed the relationship between personal, behavioral, and environmental factors and condom use among African American adolescent boys (14–19 years). Younger participants (14–15 and 16–17) were more likely to use a condom during the last sexual intercourse compared to older participants (18–19 years). High positive attachment to boy/girlfriend was associated with increased condom use. The number of sexual partners, age at their first sexual encounter, recent sexual behavior, and having an STI were also associated with increased condom use among participants. The study provides further insights into factors associated with condom use among African American adolescent boys and results can inform the development of sexual health interventions.
Poly ethylene glycol (PEG) osmopriming affects phenology, plant height and biomass yield of rainfed wheat.

Phenology, plant height and yield are important parameters of rainfed wheat affected by osmopriming. A two years experiment was conducted under rainfed condition to study the effect of osmopriming on phenology, plant height and biomass yield of rainfed wheat during 2004-05 and 2005-06 at Nuclear Institute for Food and Agriculture, Tarnab, Peshawar. Four PEG concentration HP, 10%, 20%, 30% poly ethylene glycol (PEG) and three seed priming duration (24 , 48, 72 h), along with dry seed included as a control. Two varieties (Bakhtawar-92 and Tatara) were used in this study. The experimental design was randomized complete block with split plot arrangement with three replications. Varieties were allotted to main plots whereas concentration and duration were allotted sub plots. The results showed that seed priming concentration, duration and their interaction significantly affected days to emergences, maturity and biomass yield. However, no significant effect of treatments was observed on days to heading, plant height, though their mean values were higher than control. Maximum days to heading (104.7 d) and plant height (94.4) were observed with 20% PEG 8000 and HP. Maximum days to physiological maturity (144.4) were recorded for control treatment; whereas, 10% PEG took maximum days to maturity (144.1). However, their differences were non significant. In all the experiments 24 h to 48 h duration was found to be the optimum. It is concluded that seed treated with 20% PEG for 24 h enhanced days to emergence, maturity and biomass yield of wheat compared with control and other PEG concentration over both years.
Childhood vascular phenotypes have differing associations with prenatal and postnatal growth

Supplemental Digital Content is available in the text Objective: In children aged 8--9 years, we examined the associations of linear and abdominal circumference growth during critical stages of prenatal and postnatal development with six vascular measurements commonly used as early markers of atherosclerosis and later cardiovascular disease (CVD) risk. Methods: In 724 children from the UK Southampton Women's Survey mother--offspring cohort, offspring length/height and abdominal circumference measurements were collected at 10 ages between 11 weeks’ gestation and age 8--9 years. Using residual growth modelling and linear regression, we examined the independent associations between growth and detailed vascular measures made at 8--9 years. Results: Postnatal linear and abdominal circumference growth were associated with higher childhood SBP and carotid--femoral pulse wave velocity, whereas prenatal growth was not. For example, 1SD faster abdominal circumference gain between ages 3 and 6 years was associated with 2.27 [95% confidence interval (CI): 1.56--2.98] mmHg higher SBP. In contrast, faster abdominal circumference gain before 19 weeks’ gestation was associated with greater carotid intima--media thickness [0.009 mm (0.004--0.015) per 1SD larger 19-week abdominal circumference), whereas later growth was not. We found no strong associations between prenatal or postnatal growth and DBP or measures of endothelial function. Conclusion: Higher postnatal linear growth and adiposity gain are related to higher SBP and carotid--femoral pulse wave velocity in childhood. In contrast, faster growth in early gestation is associated with greater childhood carotid intima--media thickness, perhaps resulting from subtle changes in vascular structure that reflect physiological adaptations rather than subclinical atherosclerosis.
Metachromatic leukodystrophy: A single‐center longitudinal study of 45 patients

In this study, we characterize the natural course of metachromatic leukodystrophy (MLD), explore intra/inter group differences, and identify biomarkers to monitor disease progression. This is a longitudinal observational study. Genotype and characteristics at disease onset were recorded. Time‐to‐event analyses were performed to assess time to major disease‐related milestones in different subgroups. Longitudinal trajectories of nerve conduction velocities (NCV), brain MRI score, and brainstem auditory evoked responses (BAERs) were described. We recruited 22 late‐infantile, 14 early‐juvenile, 5 late‐juvenile, and 4 adult MLD patients. Thirty‐four were prospectively evaluated (median FU time 43 months). In late‐infantile patients, the attainment of independent walking was associated with a later age at dysphagia. In early‐juvenile, the presence of isolated cognitive impairment at onset was not a favorable prognostic factor. Late‐infantile and early‐juvenile subjects showed similar rapid loss of ambulation and onset of seizures, but late‐infantile displayed earlier loss of trunk control, dysphagia, and death. We found significant differences in all major disease‐related milestones (except death) between early‐juvenile and late‐juvenile patients. Late‐juvenile and adult patients both presented with a predominant cognitive impairment, mild/no peripheral neuropathy, lower brain MRI score at plateau compared to LI/EJ, and later cerebellar involvement. NCV and BAER were consistently severely abnormal in late‐infantile but not in older subjects, in whom both NCV and BAER were variably affected, with no deterioration over time in some cases. This study clarifies intra/inter group differences between MLD subtypes and provides additional indications regarding reliable clinical and instrumental tools to monitor disease progression and to serve as areference to evaluate the efficacy of future therapeutic interventions inthe different MLD variants.
Trial of Psilocybin versus Escitalopram for Depression.

BACKGROUND Psilocybin may have antidepressant properties, but direct comparisons between psilocybin and established treatments for depression are lacking. METHODS In a phase 2, double-blind, randomized, controlled trial involving patients with long-standing, moderate-to-severe major depressive disorder, we compared psilocybin with escitalopram, a selective serotonin-reuptake inhibitor, over a 6-week period. Patients were assigned in a 1:1 ratio to receive two separate doses of 25 mg of psilocybin 3 weeks apart plus 6 weeks of daily placebo (psilocybin group) or two separate doses of 1 mg of psilocybin 3 weeks apart plus 6 weeks of daily oral escitalopram (escitalopram group); all the patients received psychological support. The primary outcome was the change from baseline in the score on the 16-item Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR-16; scores range from 0 to 27, with higher scores indicating greater depression) at week 6. There were 16 secondary outcomes, including QIDS-SR-16 response (defined as a reduction in score of >50%) and QIDS-SR-16 remission (defined as a score of ≤5) at week 6. RESULTS A total of 59 patients were enrolled; 30 were assigned to the psilocybin group and 29 to the escitalopram group. The mean scores on the QIDS-SR-16 at baseline were 14.5 in the psilocybin group and 16.4 in the escitalopram group. The mean (±SE) changes in the scores from baseline to week 6 were -8.0±1.0 points in the psilocybin group and -6.0±1.0 in the escitalopram group, for a between-group difference of 2.0 points (95% confidence interval [CI], -5.0 to 0.9) (P = 0.17). A QIDS-SR-16 response occurred in 70% of the patients in the psilocybin group and in 48% of those in the escitalopram group, for a between-group difference of 22 percentage points (95% CI, -3 to 48); QIDS-SR-16 remission occurred in 57% and 28%, respectively, for a between-group difference of 28 percentage points (95% CI, 2 to 54). Other secondary outcomes generally favored psilocybin over escitalopram, but the analyses were not corrected for multiple comparisons. The incidence of adverse events was similar in the trial groups. CONCLUSIONS On the basis of the change in depression scores on the QIDS-SR-16 at week 6, this trial did not show a significant difference in antidepressant effects between psilocybin and escitalopram in a selected group of patients. Secondary outcomes generally favored psilocybin over escitalopram, but the analyses of these outcomes lacked correction for multiple comparisons. Larger and longer trials are required to compare psilocybin with established antidepressants.

Impact of DSMES app interventions on medication adherence in type 2 diabetes mellitus: systematic review and meta-analysis

Objectives To conduct systematic review and meta-analysis of interventional studies to investigate the impact of diabetes self-management education and support (DSMES) apps on adherence in patients with type 2 diabetes mellitus (T2D). Methods PubMed, Embase, CENTRAL, Web of Science, Scopus and ProQuest were searched, in addition to references of identified articles and similar reviews. Experimental studies, reported in English, assessing DSMES app intervention’s impact on adherence and clinical outcomes of patients with T2D compared with usual care were included. Study bias was assessed using Cochrane Risk of Bias V.2. 0 tool. Analysis plan involved narrative synthesis, moderator and meta-analysis. Results Six randomised controlled trials were included, involving 696 participants (average age 57.6 years, SD 10.59). Mobile apps were mostly used for imputing clinical data, dietary intake or physical activity, and transmitting information to the provider. At 3 months, DSMES apps proved effective in improving medication adherence (standardized mean difference (SMD)=0.393, 95% CI 0.17 to 0.61), glycated haemoglobin (HbA1c) (mean difference (MD)=−0.314, 95% CI −0.477 to –0.151) and Body Mass Index (BMI) (MD=−0.28, 95% CI −0.545 to –0.015). All pooled estimates had low heterogeneity (I2 0%). Four studies had moderate risk of bias while one each was judged to be low and high risks, respectively. Conclusion DSMES apps had significant small to moderate effects on medication adherence, HbA1c and BMI of patients with T2D compared with usual care. Apps were described as reliable, easy to use and convenient, though participants were required to be phone literate. Evidence comes from feasibility trials with generally moderate risk of bias. Larger trials with longer follow-up periods using theory-based interventions are required to improve current evidence.
Gene tagging via CRISPR-mediated homology-directed repair in cassava

Abstract Research on a few model plant–pathogen systems has benefitted from years of tool and resource development. This is not the case for the vast majority of economically and nutritionally important plants, creating a crop improvement bottleneck. Cassava bacterial blight (CBB), caused by Xanthomonas axonopodis pv. manihotis (Xam), is an important disease in all regions where cassava (Manihot esculenta Crantz) is grown. Here, we describe the development of cassava that can be used to visualize one of the initial steps of CBB infection in vivo. Using CRISPR-mediated homology-directed repair (HDR), we generated plants containing scarless insertion of GFP at the 3’ end of CBB susceptibility (S) gene MeSWEET10a. Activation of MeSWEET10a-GFP by the transcription activator-like (TAL) effector TAL20 was subsequently visualized at transcriptional and translational levels. To our knowledge, this is the first such demonstration of HDR via gene editing in cassava.
Biweekly DoceAqualip in mCRPC patients beyond 20 cycles: A case series

Introduction Docetaxel 75 mg/m2 every 3 weeks for up to 10 cycles is an accepted standard regimen in metastatic castration-resistant prostate cancer (mCRPC). We report our experience with >20 cycles of biweekly nanosomal docetaxel lipid suspension (NDLS) treatment in patients with mCRPC. Case reports Cases with long-term treatment of NDLS treatment in mCRPC patients were identified from the medical records of Jawaharlal Nehru Cancer Hospital & Research Centre Bhopal, India. A total of three cases with >20 cycles of NDLS are presented here. Management and outcomes Overall, the 3 patients received biweekly NDLS at a dose of 45 mg/m2 for 22, 36, and 40 cycles, respectively, except for one patient where NDLS was initiated at 50 mg/m2 and later reduced to 45 mg/m2. All the 3 patients reported prostate-specific antigen (PSA) response (>50% decline in PSA levels from baseline). The time to treatment failure (TTF) was 14.8, 18.2, and 20.6 months in these 3 patients, respectively. PSA nadir occurred after 14, 6 and 13 cycles, respectively. The OS was 21.6, 22.2 and 25.8 months, respectively. Anemia, lymphopenia, and neutropenia were the most common adverse events. NDLS treatment was overall well-tolerated without any new safety concerns. Conclusions Biweekly NDLS for >20 cycles was effective and well-tolerated in patients with mCRPC. NDLS can potentially be used for long-term management, which may be a requirement for most patients with mCRPC.
Filter Bank-Driven Multivariate Synchronization Index for Training-Free SSVEP BCI

In recent years, multivariate synchronization index (MSI) algorithm, as a novel frequency detection method, has attracted increasing attentions in the study of brain-computer interfaces (BCIs) based on steady state visual evoked potential (SSVEP). However, MSI algorithm is hard to fully exploit SSVEP-related harmonic components in the electroencephalogram (EEG), which limits the application of MSI algorithm in BCI systems. In this paper, we propose a novel filter bank-driven MSI algorithm (FBMSI) to overcome the limitation and further improve the accuracy of SSVEP recognition. We evaluate the efficacy of the FBMSI method by developing a 6-command SSVEP-NAO robot system with extensive experimental analyses. An offline experimental study is first performed with EEG collected from nine subjects to investigate the effects of varying parameters on the model performance. Offline results show that the proposed method has achieved a stable improvement effect. We further conduct an online experiment with six subjects to assess the efficacy of the developed FBMSI algorithm in a real-time BCI application. The online experimental results show that the FBMSI algorithm yields a promising average accuracy of 83.56% using a data length of even only one second, which was 12.26% higher than the standard MSI algorithm. These extensive experimental results confirmed the effectiveness of the FBMSI algorithm in SSVEP recognition and demonstrated its potential application in the development of improved BCI systems.
Application of deep learning and molecular modeling to identify small drug-like compounds as potential HIV-1 entry inhibitors

Abstract A generative adversarial autoencoder for the rational design of potential HIV-1 entry inhibitors able to block CD4-binding site of the viral envelope protein gp120 was developed. To do this, the following studies were carried out: (i) an autoencoder architecture was constructed; (ii) a virtual compound library of potential anti-HIV-1 agents for training the neural network was formed by the concept of click chemistry allowing one to generate a large number of drug candidates by their assembly from small modular units; (iii) molecular docking of all compounds from this library with gp120 was made and calculations of the values of binding free energy were performed; (iv) molecular fingerprints of chemical compounds from the training dataset were generated; (v) training of the developed autoencoder was implemented followed by the validation of this neural network using more than 21 million molecules from the ZINC15 database. As a result, three small drug-like compounds that exhibited the high-affinity binding to gp120 were identified. According to the data from molecular docking, machine learning, quantum chemical calculations, and molecular dynamics simulations, these compounds show the low values of binding free energy in the complexes with gp120 similar to those calculated using the same computational protocols for the HIV-1 entry inhibitors NBD-11021 and NBD-14010, highly potent and broad anti-HIV-1 agents presenting a new generation of the viral CD4 antagonists. The identified CD4-mimetic candidates are suggested to present good scaffolds for the design of novel antiviral drugs inhibiting the early stages of HIV-1 infection.

Epidemiology and Molecular Basis of Multidrug Resistance in Rhodococcus equi

The development and spread of antimicrobial resistance are major concerns for human and animal health. The effects of the overuse of antimicrobials in domestic animals on the dissemination of resistant microbes to humans and the environment are of concern worldwide. Rhodococcus equi is an ideal model to illustrate the spread of antimicrobial resistance at the animal-human-environment interface because it is a natural soil saprophyte that is an intracellular zoonotic pathogen that produces severe bronchopneumonia in many animal species and humans. SUMMARY The development and spread of antimicrobial resistance are major concerns for human and animal health. The effects of the overuse of antimicrobials in domestic animals on the dissemination of resistant microbes to humans and the environment are of concern worldwide. Rhodococcus equi is an ideal model to illustrate the spread of antimicrobial resistance at the animal-human-environment interface because it is a natural soil saprophyte that is an intracellular zoonotic pathogen that produces severe bronchopneumonia in many animal species and humans. Globally, R. equi is most often recognized as causing severe pneumonia in foals that results in animal suffering and increased production costs for the many horse-breeding farms where the disease occurs. Because highly effective preventive measures for R. equi are lacking, thoracic ultrasonographic screening and antimicrobial chemotherapy of subclinically affected foals have been used for controlling this disease during the last 20 years. The resultant increase in antimicrobial use attributable to this “screen-and-treat” approach at farms where the disease is endemic has likely driven the emergence of multidrug-resistant (MDR) R. equi in foals and their environment. This review summarizes the factors that contributed to the development and spread of MDR R. equi, the molecular epidemiology of the emergence of MDR R. equi, the repercussions of MDR R. equi for veterinary and human medicine, and measures that might mitigate antimicrobial resistance at horse-breeding farms, such as alternative treatments to traditional antibiotics. Knowledge of the emergence and spread of MDR R. equi is of broad importance for understanding how antimicrobial use in domestic animals can impact the health of animals, their environment, and human beings.
Japanese Translation and Validation of the Environmental Assessment Tool–Higher Care

Objective: The purpose of this study was to translate the Environmental Assessment Tool–Higher Care (EAT-HC) into Japanese and validate its use in small-scale group living facilities in Japan. Background: Environment of a facility is shown to improve its residents’ quality of life (QOL). Japan’s “welfare-based nursing homes for the elderly” are gradually shifting to a small-scale group living concept called group care units (GCUs). However, there is no appropriate environmental tool available for evaluating GCUs. The application of valid environmental assessment tools brings about a better understanding of the nature of good environments and the relationship between environments and outcomes for residents living with dementia. Methods: The study had a mixed method design conducted in several steps, covering translation and adaptation. The translation phase involved (1) forward translation and (2) backward translation. The adaptation phase involved (3) content validity and homogeneity reliability and (4) concurrent validity and interrater reliability. Results: 71 Items (92%) met the acceptable level of content validity (item-content validity index [CVI] > .79) and had good scale-CVI of . 88. Concurrent validity was confirmed between . 65 and . 78 (p < .001). For reliability test, the internal consistency of six subscales was between . 88 and . 98. Overall interobserver agreement was 90.3%. Intraclass correlation coefficients were . 80–. 98 (p < .001), and homogeneity reliability coefficient for all items was >. 76 (p < .01). Conclusions: Validation of the EAT-HC-Japanese Version (EAT-HC-JV) was confirmed as an appropriate tool for environmental assessment to enhance the QOL in Japan’s GCUs. For future study, we plan to modify the EAT-HC-JV to adapt to Japanese cultural aspects in order to increase its usability in Japan.
