0%) of patients had BDI ≥ 10 and 18.0% had major depressive disorder. Platelet serotonin response was found to be augmented in depressed patients with low LVEF compared to depressed patients with normal LVEF (p less then 0.020). However, the presence of LV dysfunction was found to be similar in both depressed (32.3%) and non-depressed (36.2%) patients (p = 0.714). This suggests alternative factors contribute to poor cardiovascular outcomes in depressed patients that are independent of LV function in post ACS patients.
There is evidence that the exposure to a major natural disaster such as the 2010 earthquake in Haiti may have devastating short- and long-term effects on children's mental health and overall development. This review summarizes what has been reported in the past 3years (2017-2020) regarding emotional, psychological, and behavioral effects of exposure to this particular earthquake on children 10years and older.
Twenty-six articles were screened, of which twenty-one were selected for final analysis. The main themes addressed in the literature over the 3years concerned prevalence of post-traumatic stress disorder (PTSD), depression, determinants of resilience factors, prevalence of sexual violence as well as prenatal exposure, and subsequent autism behaviors/symptoms. The majority of the findings analyzed in this review on mental health in young Haitian survivors of the 2010 earthquake came from cross-sectional studies conducted in West region of Haiti, spefically Port-au-Prince. There was a paucity of longitn's development and mental health, which are much needed on this disaster-prone island.
Sugarcane transgenic overexpressing EaGly III from Erianthus arundinaceus showed enhanced water deficit stress tolerance. Methylglyoxal (MG), an α-ketoaldehyde formed from either glycolysis or TCA cycle, is capable of causing total cellular damage via the generation of reactive oxygen species (ROS), advanced glycation end products (AGEs) and nucleic acid degradation. Glyoxalase pathway is a ubiquitous pathway known for detoxification of MG, involving key enzymes glyoxalase I (Gly I) and glyoxalase II (Gly II). Recently, a novel and an additional enzyme in glyoxalase pathway, viz., glyoxalase III (Gly III), has been discovered which possesses DJ-1/PfpI domain recognized for detoxifying MG in a single step process without requirement of any coenzyme. In the present study, a Gly III gene isolated from Erianthus arundinaceus, a wild relative of sugarcane, overexpressed in commercially cultivated sugarcane hybrid Co 86032 was assessed for drought tolerance. Morphometric observations revealed that transgenic sugaw in transgenic plants as compared to wild type (WT). Transgenics resulted in higher relative water content, chlorophyll content, gas exchange parameters, photosynthetic efficiency, proline content and soluble sugars upon water deficit stress. In addition, higher and stable level of superoxide dismutase and peroxidase activities were observed along with minimal lipid peroxidation during drought stress signifying the tolerance mechanism exhibited by transgenic events. There was no significant structural change observed in the root anatomy of transgenic plants. Altogether, EaGly III gene could be considered as a potential candidate for conferring water deficit stress tolerance for sugarcane and other agricultural crops.
A comparative proteomic study between WT and SAR-compromised rsi1/fld mutant reveals a set of proteins having possible roles in the SAR development. A partly infected plant shows enhanced resistance during subsequent infection through the development of systemic acquired resistance (SAR). Mobile signals generated at the site of primary infection travel across the plant for the activation of SAR. These mobile signals are likely to cause changes in the expression of a set of proteins in the distal tissue, which contributes to the SAR development. However, SAR-specific proteome is not revealed for any plant. The reduced systemic immunity 1 (rsi1)/(allelic to flowering locus D; fld) mutant of Arabidopsis is compromised for SAR but shows normal local resistance. Here we report the SAR-specific proteome of Arabidopsis by comparing differentially abundant proteins (DAPs) between WT and fld mutant. Plants were either mock-treated or SAR-induced by primary pathogen inoculation. For proteomic analysis, samples were c pathogen treatment in WT and fld mutant. The DAPs were categorized into different functional groups along with their subcellular localization. The majority of DAPs are involved in metabolic processes and stress response. Among the subcellular compartments, plastids contained the highest number of DAPs, suggesting the importance of plastidic proteins in SAR activation. The findings of this study would provide resources to engineer efficient SAR activation traits in Arabidopsis and other plants.
To test for differences in DISE findings in children sedated with propofol versus dexmedetomidine. We hypothesized that the frequency of ≥ 50% obstruction would be higher for the propofol than dexmedetomidine group at the dynamic levels of the airway (velum, lateral walls, tongue base, and supraglottis) but not at the more static adenoid level.
A single-center retrospective review was performed on children age 1-18 years with a diagnosis of sleep disordered breathing or obstructive sleep apnea (OSA) who underwent DISE from July 2014 to Feb 2019 scored by the Chan-Parikh scale sedated with either propofol or dexmedetomidine (with or without ketamine). Logistic regression was used to test for a difference in the odds of ≥ 50% obstruction (Chan-Parikh score ≥ 2) at each airway level with the use of dexmedetomidine vs. propofol, adjusted for age, sex, previous tonsillectomy, surgeon, positional OSA, and ketamine co-administration.
Of 117 subjects, 57% were sedated with propofol and 43% with dexmedetomidine. Subjects were 60% male, 66% Caucasian, 31% obese, 38% syndromic, and on average 6.5 years old. Thirty-three percent had severe OSA and 41% had previous tonsillectomy. There was no statistically significant difference in the odds of ≥ 50% obstruction between the two anesthetic groups at any level of the airway with or without adjustment for potential confounders.
We did not find a significant difference in the degree of upper airway obstruction on DISE in children sedated with propofol versus dexmedetomidine. Prospective, randomized studies would be an important next step to confirm these findings.

To assess the effect of Nigella sativa (N.S) oil supplements on CVD risk factors in a crossover design for the first time.
Obese and overweight healthy women were randomized to receive N.S oil (2000mg/day) and placebo. This intervention period lasted for 8weeks and separated by a 4-week washout period. An iso-caloric diet was given to every individual throughout the study. Blood pressure, lipid profile, atherogenic indices and liver enzymes were measured. Pkcross procedure was performed for statistical analyses using Stata software. Cohen's d was estimated as effect size for all outcomes to measure the magnitude of the effects.
Thirty-nine participants completed the study. Capsules of N.S increased serum high-density lipoprotein cholesterol (Cohen's d = 0.47, P = 0.009), reduced low-density lipoprotein cholesterol (Cohen's d = -0.33, P = 0.031), reduced TC/HDL-C ratio (as an atherogenic index, Cohen's d = -0.9, P < 0.001), reduced serum glutamic-oxaloacetic transaminase (Cohen's d = 0-0.5, P = 0.038) and reduced systolic blood pressure (Cohen's d = -0.4, P < 0.001). There was no effect on diastolic blood pressure measures (P = 0.96).
The overall improvements in cardiovascular disease (CVD) risk factors showed beneficial effects of N.S supplements among adults with obesity to prevent possible cardiovascular diseases. More studies with different designs and in other populations are suggested to clarify the exact effects of N.S as a complementary therapy for modulating CVD risk factors in individuals with overweight and obesity.

Recent advances in experimental models, methodology, and our understanding of disease processes at the molecular and cellular levels reveal opioid-HIV interactions with increasing clarity. However, despite the substantial new insight, the unique impact of opioids on the severity, progression, and prognosis of neuroHIV and HIV-associated neurocognitive disorders (HAND) are not fully understood. In this review, we explore, in detail, what is currently known about mechanisms underlying opioid interactions with HIV, with emphasis on individual HIV-1-expressed gene products at the molecular, cellular and systems levels. Furthermore, we review preclinical and clinical studies with a focus on key considerations when addressing questions of whether opioid-HIV interactive pathogenesis results in unique structural or functional deficits not seen with either disease alone. selleck chemicals llc These considerations include, understanding the combined consequences of HIV-1 genetic variants, host variants, and μ-opioid receptor (MOR) and HIV chemokine co-receptor interactions on the comorbidity. Lastly, we present topics that need to be considered in the future to better understand the unique contributions of opioids to the pathophysiology of neuroHIV. Graphical Abstract Blood-brain barrier and the neurovascular unit. With HIV and opiate co-exposure (represented below the dotted line), there is breakdown of tight junction proteins and increased leakage of paracellular compounds into the brain. Despite this, opiate exposure selectively increases the expression of some efflux transporters, thereby restricting brain penetration of specific drugs.
To report on our institutional cohort of patients and review the literature of medulloblastoma patients who developed skull/subdural-based lesions following treatment.
Following institutional review board (IRB) approval, we retrospectively reviewed the medical records of four children with a history of treated medulloblastoma who developed non-specific skull-based/subdural lesions incidentally found on surveillance imaging.
Biopsies of the lesions proved the pathology to be low grade and included inflammatory myofibroblastic tumor, cortical fibrous defect consistent with fibroma, fibrous tissue, and fibrous dysplasia. The finding of calvarial or subdural fibrous lesions in children following therapy for medulloblastoma was noted in four out of 201 (136 with available follow-up data) medulloblastoma patients seen or discussed in our institution over the past 10years.
These lesions can grow over time and pose a differential diagnostic challenge with metastatic disease when identified. The skull and subdural space should be scrutinized for secondary lesions on surveillance imaging of patients with medulloblastoma who have received craniospinal irradiation as knowledge of this benign occurrence will assist with management.
