We further show that loss of LcytB and Steap3 in macrophages infected with UTI89 led to increased proliferation of intracellular UTI89 suggesting that the endolysosomal system is retaining Fe3+ that can be used for proliferation of intravesicular pathogens. Together, our findings reveal an important role for both LcytB and Steap3 in macrophage iron recycling and suggest that limiting iron recycling by decreasing expression of endolysosomal reductases is an innate immune response to protect against pathogen proliferation and sepsis.

Given the ongoing battle with opioid abuse and overuse in the United States, new strategies are consistently being implemented to reduce opioid utilization and overprescribing.

The purpose of this study was to determine if a more regulated explicit pain management instruction plan could reduce the number of opioids taken.

Blinded randomized prospective study comparing a total of 110 (Group A = 55, Group B = 55) women who underwent elective outpatient bilateral breast reduction surgery by 2 different plastic surgeons. Patients were randomly divided into either Group A (control) that received general pain management instructions or Group B (experimental) that received explicit pain management instructions from the surgeons and nurses. Participants were asked to record the number of times they treated their pain with each separate modality. They were also asked to record their average daily pain scale for the days that they were treating their pain.

Patients in Group B took on average 1.5 oxycodone (5 mg) and patients in Group A took on average 5.7 oxycodone (5 mg) (P < 0.01). Thirty-four patients in Group B took no oxycodone. Patients in Group B also had statistically significant lower subjective pain scores.

Based on these results, it appears that standardizing how patients are instructed to treat their pain postoperatively may reduce the number of narcotics needed, thus reducing the number of narcotics prescribed without compromising pain control.

Phosphatidic acid (PA) and lysophosphatidic acid acyltransferases (LPAATs) might be critical for the secretory pathway. Four extra-plastidial LPAATs (LPAAT2, 3, 4, and 5) were identified in Arabidopsis thaliana. Troglitazone concentration These AtLPAATs display a specific enzymatic activity converting lysophosphatidic acid to PA and are located in the endomembrane system. We investigate a putative role for AtLPAATs 3, 4, and 5 in the secretory pathway of root cells through genetical (knockout mutants), biochemical (activity inhibitor, lipid analyses), and imaging (live and immuno-confocal microscopy) approaches. Treating a lpaat4;lpaat5 double mutant with the LPAAT inhibitor CI976 produced a significant decrease in primary root growth. The trafficking of the auxin transporter PIN2 was disturbed in this lpaat4;lpaat5 double mutant treated with CI976, whereas trafficking of H+-ATPases was unaffected. The lpaat4;lpaat5 double mutant is sensitive to salt stress, and the trafficking of the aquaporin PIP2;7 to the plasma membrane in the lpaat4;lpaat5 double mutant treated with CI976 was reduced. We measured the amounts of neo-synthesized PA in roots, and found a decrease in PA only in the lpaat4;lpaat5 double mutant treated with CI976, suggesting that the protein trafficking impairment was due to a critical PA concentration threshold.

Recent US studies report rising rates of mortality and in-hospital complications following catheter ablation of atrial fibrillation (AF), but whether this is a global phenomenon is uncertain. The aim of this study was to examine trends in 30-day mortality and complications following AF ablation in Australia and New Zealand (ANZ) from 2008 to 2017.

We identified 37243 AF (mean age 62.4 ± 11.5years, 29.6% females, 94.5% elective procedures) ablations using national hospitalization data. The primary outcome was occurrence of any complication, including all-cause mortality, within 30days of discharge. Trends were evaluated using logistic regression adjusting for changes in patient characteristics. The annual number of ablations increased from 1359 (2008) to 5115 (2017). Patients' age and rates of heart failure (9.8-10.6%), diabetes (6.8-12.4%), and chronic kidney disease (2.2-4.1%) also increased over time. From 2008 to 2017, the overall rate of complications declined from 7.51% to 5.04% [adjusted odds ratio (aOR) 0.96 (95% confidence interval, CI, 0.94-0.97)/year]. Rates of pericardial effusion [1.69-0.70%, aOR 0.93 (0.89-0.97)], bleeding [4.49-2.74%, aOR 0.94 (0.92-0.96)], and vascular injury [0.52-0.16%, aOR 0.91 (0.85-0.98)] declined, but rates of acute kidney injury [0.15-0.68%, aOR 1.16 (1.08-1.25)] and infection [0.15-0.57%, aOR 1.07 (1.01-1.14)] increased over time. The overall 30-day mortality rate was low (0.11%) and unchanged [0.00-0.16%, aOR 0.99 (0.88-1.11)].

Despite a five-fold increase in AF ablations and the rising risk profile of patients, complications following AF ablation declined by 30% from 2008 to 2017 in ANZ. Procedure-related death was uncommon and occurred in less than 1 in 850 patients.

AgNPs can be introduced into human bodies via inhalation, either intentionally (intranasal administration of AgNPs) or unintentionally (environmental pollution, accidental release, or occupational exposure). Recent studies have shown that intranasal exposure of experimental animals to AgNPs can lead to the accumulation of Ag in brain tissues. However, there is little information available concerning what forms of Ag (particulate and ionic) exist in brain tissues. This study aimed to investigate whether particulate Ag exists in rat brains following intranasal exposure of AgNPs at 1 mg/kg/day using multiple analytical techniques. The results demonstrated that Ag-containing particles were presented in AgNPs-exposed rat brains, accounting for 20.2-68.1% of the total Ag. The mass concentrations of Ag-containing particles in brain tissues increased with exposure time but only decreased by 37.5% after elimination for 4 weeks upon exposure cessation. The size of Ag-containing particles identified in rat brains was larger than the original AgNPs. The Ag-containing particles identified in the rat brain were composed of multiple elements, including Ag, sulfur, and selenium with atomic percentages of 45.8%, 37.5%, and 16.7%, respectively. The finding highlighted the occurrence and accumulation of transformed AgNPs containing S and Se in rat brains after intranasal exposure to AgNPs, implying potential risks for brain health.The plant genus Bidens (Asteraceae or Compositae; Coreopsidae) is a species-rich and circumglobally distributed taxon. The 19 hexaploid species endemic to the Hawaiian Islands are considered an iconic example of adaptive radiation, of which many are imperiled and of high conservation concern. Until now, no genomic resources were available for this genus, which may serve as a model system for understanding the evolutionary genomics of explosive plant diversification. Here, we present a high-quality reference genome for the Hawai'i Island endemic species B. hawaiensis A. Gray reconstructed from long-read, high-fidelity sequences generated on a Pacific Biosciences Sequel II System. The haplotype-aware, draft genome assembly consisted of ~6.67 Giga bases (Gb), close to the holoploid genome size estimate of 7.56 Gb (± 0.44 SD) determined by flow cytometry. After removal of alternate haplotigs and contaminant filtering, the consensus haploid reference genome was comprised of 15,904 contigs containing ~3.48 Gb, with a contig N50 value of 422,594. The high interspersed repeat content of the genome, approximately 74%, along with hexaploid status, contributed to assembly fragmentation. Both the haplotype-aware and consensus haploid assemblies recovered >96% of Benchmarking Universal Single-copy Orthologs. Yet, the removal of alternate haplotigs did not substantially reduce the proportion of duplicated benchmarking genes (~79% versus ~68%). This reference genome will support future work on the speciation process during adaptive radiation, including resolving evolutionary relationships, determining the genomic basis of trait evolution, and supporting ongoing conservation efforts.Molecules isolated and identified from plant origin are used to manufacture most chemotherapeutic drugs for cancer treatment. We assumed that these plant extracts contain prolific bioactive compounds with potent antiproliferative activities and could be effective against different human cancer cells. Ethanolic extracts were prepared from Chelidonium majus, Myrica cerifera, Fumaria indica, Nigella sativa, and Silybum marianum, and the antiproliferative assay was performed in HepG2 and HeLa human cancer cell lines. All plants extract exhibited antiproliferative potential against studied cancer cell lines in the dose and time-dependent manner. Chelidonium majus and Silybum marianum have shown promising results against HepG2 and HeLa cells, respectively, followed by Myrica cerifera, Fumaria indica, and Nigella sativa. Results indicated that utilization of whole plant extract as anticancer compounds could be of great value in generating novel chemotherapeutic drugs.

Newborn oil massage is a widespread practice. Vigorous massage with potentially harmful products and forced removal of vernix may disrupt skin barrier integrity. Hospitalized, very-preterm infants treated with sunflower seed oil (SSO) have demonstrated improved growth but community-based data on growth and health outcomes are lacking.

We aimed to test whether SSO therapy enhances neonatal growth and reduces morbidity at the population level.

We conducted an open-label, controlled trial in rural Uttar Pradesh, India, randomly allocating 276 village clusters equally to comparison (usual care) and intervention comprised of promotion of improved massage practices exclusively with SSO, using intention-to-treat and per-protocol mixed-effects regression analysis.

We enrolled 13,478 and 13,109 newborn infants in demographically similar intervention and comparison arms, respectively. Adherence to exclusive SSO increased from 22.6% of intervention infants enrolled in the first study quartile to 37.2% in the lasunity settings, and to confirm these results in other settings.This trial was registered at www.isrctn.com as ISRCTN38965585 and http//ctri.nic.in as CTRI/2014/12/005282.

SSO therapy improved neonatal growth, and reduced morbidities when applied exclusively, across the facility-community continuum of care at the population level. Further research is needed to improve demand for recommended therapy inside hospital as well as in community settings, and to confirm these results in other settings.This trial was registered at www.isrctn.com as ISRCTN38965585 and http//ctri.nic.in as CTRI/2014/12/005282.

Vitamin D insufficiency is associated with risks of cardiovascular diseases (CVD) and cancer in observational studies, but evidence for benefits with vitamin D supplementation is limited.

To investigate the effects of vitamin D3 supplementation on CVD and cancer incidences.

The study was a 5-year, randomized, placebo-controlled trial among 2495 male participants≥60 years and post-menopausal female participants≥65 years from a general Finnish population who were free of prior CVD or cancer. The study had 3 arms placebo, 1600 IU/day, or 3200 IU/day vitamin D3. Follow-up was by annual study questionnaires and national registry data. A representative subcohort of 551 participants had more detailed in-person investigations. The primary endpoints were incident major CVD and invasive cancer. Secondary endpoints included the individual components of the primary CVD endpoint (myocardial infarction, stroke, and CVD mortality), site-specific cancers, and cancer death.

During the follow-up, there were 41 (4.9%), 42 (5.
