INTRODUCTION: While marijuana has been legal for medical purposes in California since 1996, little is known about the health histories of young adult medical marijuana patients who are a significant proportion of medical marijuana patients. We examined whether young adult medical marijuana patients reported health conditions and motivations for use that were consistent with medical use of marijuana in California. METHODS: Young adults (N = 366) aged 18 to 26 years were sampled in Los Angeles in 2014-2015 and segmented into medical marijuana 'patients' (n = 210), marijuana users with a current recommendation, and non-patient users or 'non-patients' (n = 156), marijuana users who never had a medical marijuana recommendation...

AIM: Perinatal deaths occurring outside the neonatal intensive care unit (NICU) are rarely recorded in outcome studies, despite having a direct impact on perinatal statistics. Our aim was to investigate the timing and modes of perinatal deaths that occurred outside the NICU and changes over time. METHOD: We reviewed all perinatal deaths from 22 weeks of gestation onwards, without NICU admissions, during two periods in a Canadian tertiary mother and baby hospital and categorised deaths according to nine specific categories...

The genus Laminaria has a wide distribution range compared with other kelp genera because it is found in both the North and the South Atlantic, on both sides of the North Pacific, as well as in the Mediterranean. Hypotheses behind this biogeographical pattern have been discussed by several authors but have not yet been fully evaluated with time-calibrated phylogenies. Based on the analysis of four molecular markers (ITS2, rbcL, atp8 and trnWI), our goal was to reassess the Laminaria species diversity in South Africa, assess its relationship to the other species distributed in the South Atlantic and reconstruct the historical biogeography of the genus...

Previous publications list ten species in the Laurencia complex from South Africa with all ascribed to the genus Laurencia sensu stricto. However, the diversity of the complex in South Africa has not yet been reassessed following the numerous recent taxonomic changes. The present study investigated the phylogenetic relationships and taxonomy of this group in South Africa using recent collections. Methods included a molecular phylogenetic analysis of plastid rbcL gene sequences (a total of 146; including eleven outgroup taxa) using Bayesian Inference, and the examination of morphological and anatomical characters, including the number of corps en cerise when present...

Type 2 diabetes mellitus is becoming increasingly prevalent worldwide and has become one of the greatest threats to global health. Bariatric surgery was initially designed to achieve weight loss and subsequently was noted to induce improvements or remission of type 2 diabetes. Currently, these bariatric operations such as Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are the most effective procedures for the treatment of obesity and type 2 diabetes mellitus worldwide. However, the specific mechanism mediating the beneficial effects of metabolic surgery has remained largely unknown...

This study examines spatially variable stand structure and fire-climate relationships at a low elevation forest-grassland ecotone in west central British Columbia, Canada. Fire history reconstructions were based on samples from 92 fire-scarred trees and stand demography from 27 plots collected over an area of about 7 km(2) . We documented historical chronologies of widespread fires and localized grassland fires between AD 1600 and 1900. Relationships between fire events, reconstructed values of the Palmer Drought Severity Index and annual precipitation were examined using superposed epoch and bivariate event analyses...

Sustainable development aims at addressing economic, social, and environmental concerns, but the current lack of responsive environmental governance hinders progress. Short-term economic development has led to limited actions, unsustainable resource management, and degraded ecosystems. The UN Sustainable Development Goals (SDGs) may continue to fall short of achieving significant progress without a better understanding of how ecosystems contribute to achieving sustainability for all people. Ecosystem governance is an approach that integrates the social and ecological components for improved sustainability and includes principles such as adaptive ecosystem co-management, subsidiarity, and telecoupling framework, as well as principles of democracy and accountability...

Prostate cancer is the most common solid tumor malignancy in men worldwide. Treatment with surgery and radiation can be curative in organ-confined disease. Unfortunately, about one third of men develop biochemically recurrent disease based only on rising prostate-specific antigen (PSA) in the absence of visible disease on conventional imaging. For these patients with biochemical recurrent prostate cancer, there is no uniform guideline for subsequent management. Based on available data, it seems prudent that biochemical recurrent prostate cancer should initially be evaluated for salvage radiation or prostatectomy, with curative intent...

P Maxwell Slepian, Christopher R France
The Pain Resilience Scale was recently developed to assess dimensions of resilience critical to pain-related adaptation and was found to predict experimental pain sensitivity in a pain-free population. Pain resilience has also been theoretically linked to behavioral persistence despite pain. To date, however, this hypothesis has not been experimentally tested. To address this gap in the literature, in the current study 105 healthy young adults underwent a baseline administration of the Paced Auditory Serial Addition Test (PASAT), a stressful mental arithmetic task, delivered with somatosensory distraction (i...

Peroxiredoxin 2 (Prx2) is a redox enzyme that is abundantly expressed in red blood cells (RBCs) and has been the focus of clinical attention for monitoring the oxidative status. We previously developed a method to quantify the reduced and hyperoxidized forms of Prx2 in human RBCs using reverse-phase high-performance liquid chromatography (HPLC). In the present study, we investigated the hyperoxidative status of Prx2 at the molecular level in a post-translational modification analysis using a liquid chromatography-tandem mass spectrometry (LC-MS/MS) system...

REVIEW

PURPOSE OF REVIEW: This review focuses on the differential effects of contemporary antiretrovirals on systemic inflammation as heightened immune activation is linked to important co-morbidities and mortality with HIV infection. RECENT FINDINGS: Antiretroviral therapy (ART) reduces dramatically systemic inflammation and immune activation, but not to levels synchronous with HIV-uninfected populations. In one ART initiation trial, integrase inhibitors appear to reduce inflammation to a greater degree than non-nucleoside reverse transcriptase inhibitors (NNRTIs); however, it is not clear that there are beneficial effects on inflammation resulting from treatment with integrase inhibitors compared to PIs, between PIs and NNRTIs, between specific nucleoside reverse transcriptase inhibitors, or with maraviroc in ART-naïve patients...

Flow cytometry is a powerful tool for phenotypic and functional analyses of single immune cells. The increasing capability of flow cytometry technology has driven a more detailed understanding of immune cell subsets and functions in complex cellular systems such as the developing human decidua/placenta. We propose a standardized procedure for the isolation and analysis of human decidual natural killer (dNK) cells and this method can be extended to investigation of other uterine lymphocytes. Here this platform is used to examine the expression of sphingosine-1-phosphate (S1P) receptor and functional growth factors by dNK cells...

Astrocytes in the mammalian central nervous system are interconnected by gap junctions made from connexins of the subtypes Cx30 and Cx43. These proteins may exist as hemichannels in the plasma membrane in the absence of a 'docked' counterpart on the neighboring cell. A variety of stimuli are reported to open the hemichannels and thereby create a permeation pathway through the plasma membrane. Cx30 and Cx43 have, in their hemichannel configuration, been proposed to act as ion channels and membrane pathways for different molecules, such as fluorescent dyes, ATP, prostaglandins, and glutamate...

Recently, the loss and dystrophy of hippocampal microglia induced by chronic unpredictable stress (CUS) has been reported to mediate the development of major depression in mice whose microglial cells were labeled with enhanced green fluorescent protein-conjuncted-CX3C receptor type 1. However, whether this happens in endogenous microglia with no genetic intervention remains unclear. Here, we addressed this issue in mice treated with different types of chronic stresses, including the CUS, chronic restraint stress (CRS) and chronic social defeat stress (CSDS)...

This review outlines nitrogen (N) responses in crop production and potential management decisions to ameliorate abiotic stresses for better crop production. N is a primary constituent of the nucleotides and proteins that are essential for life. Production and application of N fertilizers consume huge amounts of energy, and excess is detrimental to the environment. Therefore, increasing plant N use efficiency (NUE) is important for the development of sustainable agriculture. NUE has a key role in crop yield and can be enhanced by controlling loss of fertilizers by application of humic acid and natural polymers (hydrogels), having high water-holding capacity which can improve plant performance under field conditions...

BACKGROUND: Trastuzumab following anthracycline causes cardiotoxicity in up to 28% of patients. Although the cardiotoxicity is often irreversible once cardiac dysfunction is detected, the early predictor has not been established yet. METHODS: We prospectively observed breast cancer patients treated with anthracycline or trastuzumab at Tonan Hospital. All patients underwent echocardiography and blood sampling at baseline, and every three months during chemotherapy...

To date, all studies of aflatoxin B1 (AFB1) transformation in soil or in purified mineral systems have identified aflatoxins B2 (AFB2) and G2 (AFG2) as the primary transformation products. However, identification in these studies was made using thin layer chromatography which has relatively low resolution, and these studies did not identify a viable mechanism by which such transformations would occur. Further, the use of methanol as the solvent delivery vehicle in these studies may have contributed to formation of artifactual transformation products...

Hua Li, Yangbing Zhao
Chimeric antigen receptor (CAR) T cell therapy is a promising cancer treatment that has recently been undergoing rapid development. However, there are still some major challenges, including precise tumor targeting to avoid off-target or "on-target/off-tumor" toxicity, adequate T cell infiltration and migration to solid tumors and T cell proliferation and persistence across the physical and biochemical barriers of solid tumors. In this review, we focus on the primary challenges and strategies to design safe and effective CAR T cells, including using novel cutting-edge technologies for CAR and vector designs to increase both the safety and efficacy, further T cell modification to overcome the tumor-associated immune suppression, and using gene editing technologies to generate universal CAR T cells...
