ed in the recently described new form of Bmab-associated hyaline occlusive glomerular microangiopathy. This form should be considered in proteinuric cancer patients treated with VEGF-VEGFR2 inhibitors. Discontinuing VEGF-VEGFR2 inhibitors may lead to improvement of glomerular microangiopathy induced by these drugs.Both Moso bamboo (Phyllostachys pubescens) and tree forests have a large biomass; they are considered to play an important role in ecosystem carbon budgets. The scaling relationship between individual whole-shoot (i.e., aboveground parts) respiration and whole-shoot mass provides a clue for comparing the carbon budgets of Moso bamboo and tree forests. However, nobody has empirically demonstrated whether there is a difference between these forest types in the whole-shoot scaling relationship. We developed whole-shoot chambers and measured the shoot respiration of 58 individual mature bamboo shoots from the smallest to the largest in a Moso bamboo forest, and then compared them with that of 254 tree shoots previously measured. For 30 bamboo shoots, we measured the respiration rate of leaves, branches, and culms. We found that the scaling exponent of whole-shoot respiration of bamboo fitted by a simple power function on a log-log scale was 0.843 (95 % CI 0.797-0.885), which was consistent with that of trees, 0.826 (95 % CI 0.799-0.851), but higher than 3/4, the value typifying the Kleiber's rule. The respiration rates of leaves, branches, and culms at the whole-shoot level were proportional to their mass, revealing a constant mean mass-specific respiration of 1.19, 0.224, and 0.0978 µmol CO2 kg- 1 s- 1, respectively. These constant values suggest common traits of organs among physiologically integrated ramets within a genet. Additionally, the larger the shoots, the smaller the allocation of organ mass to the metabolically active leaves, and the larger the allocation to the metabolically inactive culms. Therefore, these shifts in shoot-mass partitioning to leaves and culms caused a negative metabolic scaling of Moso bamboo shoots. The observed convergent metabolic scaling of Moso bamboo and trees may facilitate comparisons of the ecosystem carbon budgets of Moso bamboo and tree forests.

COVID-19 is the first global pandemic in more than 100years, and at its onset, the effects were largely unknown. Immunocompromised patients, including IBD, were presumed to have higher risk.

We hypothesized patients with IBD would have higher-than-baseline anxiety, high perceived vulnerability and significant lifestyle impacts as a result of the pandemic. We sought to assess the impact of these changes on disease and management.

A cross-sectional study of patients with Crohn's disease, ulcerative colitis and IBD-unspecified was conducted. Patients were invited to participate by email in an IRB-approved brief, voluntary survey. Survey questions focused on disease characteristics, healthcare access and self-reported psychological well-being.

Responses from 492 (CD = 337, UC = 141,IC = 14) patients were included in the analysis. The majority of patients with IBD had increased anxiety since the pandemic, which correlated with an increase in GI symptoms. This risk of symptoms was mitigated by communication with their provider. Many patients had lifestyle changes including requesting time off work due to perceived vulnerability and changes in eating habits.

Our findings support an increase in illness-associated anxiety and perceived vulnerability among patients with IBD during the COVID-19 pandemic. Open communication with providers is important to maintain adequate control of disease and reduce symptoms of flares triggered by ongoing stress.

The objective of this study is to determine whether an initial methotrexate (MTX) dosage is associated with an increased risk of liver toxicity in patients with rheumatoid arthritis (RA).

This retrospective study included 730 RA patients who started MTX treatment between 2004 and 2019 at the rheumatology clinic at Seoul National University Hospital. The patients were divided into three groups according to the initial dosage of MTX they received low (MTX ≤ 7.5mg/week), intermediate (MTX 10-12.5mg/week), and high (MTX ≥ 15mg/week) dosage groups. Hepatotoxicity, defined as elevations in aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) levels more than twofold above the upper limit of normal (2 × ULN), was examined during 90days of MTX treatment. Predictors of hepatotoxicity were identified using logistic regression analyses.

Of the 730 patients, 10 (1.4%) patients developed hepatotoxicity. The rate of hepatotoxicity was not different between the three MTX dosage groups. Dulaglutide Glucagon Receptor peptide Univariate lognts with a baseline liver function test (LFT) abnormality or receiving concomitant leflunomide treatment should be monitored closely for LFT abnormalities during the early phase of MTX treatment.In the current work, the chemical reactivity of some trivalent phosphorus derivatives R2PR' towards polyhaloalkanes CCl3POR ' '2 was studied by the quantum method DFT/B3LYP/6-311G(d,p). The introduction of substituents for the trivalent phosphorus derivative and polyhaloalkane allowed us to have more information on these reactions. On the one hand, the calculation of reactivity indices derived from the DFT/B3LYP/6-311G(d,p) method and the gapLUMO - HOMO show that trivalent organophosphorus derivatives behave as nucleophiles, while polyhaloalkanes act as electrophiles. link2 On the other hand, the calculation of the activation barrier and the determination of the free enthalpy variation prove that the kinetic and thermodynamic products of these reactions result from the nucleophilic attack of the phosphorus atom on the chlorine halogen. All these theoretical predictions are in very good agreement with the experimental results.Catechin, a flavonol belonging to the flavonoid group of polyphenols is present in many plant foods. The present study was done to evaluate the effect of catechin on various inflammatory mediators using lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. The effect of catechin on total cyclooxygenase (COX) activity, 5-lipoxygenase (5-LOX), myeloperoxidase, nitrite and inducible nitric oxide synthase (iNOS) level, secretion of tumor necrosis factor-α (TNF-α) and interleukin-10 (IL-10) were assessed in LPS-stimulated RAW 264.7 cells. The expression of COX-2, iNOS, TNF-α, nuclear factor-ĸB (NF-κB) and p38 mitogen-activated protein kinase (MAPK) genes were also investigated. The effect was further analyzed using human PBMCs by assessing the level of TNF-α and IL-10. The study demonstrated that the inflammatory mediators such as COX, 5-LOX, nitrite, iNOS, and TNF-α were significantly inhibited by catechin in a concentration-dependent manner whereas IL-10 production was up-regulated in RAW 264.7 cells. Moreover, catechin down-regulated the mRNA level expression of COX-2, iNOS, TNF-α, NF-κB and p38 MAPK. The current study ratifies the beneficial effect of catechin as a dietary component in plant foods to provide protection against inflammatory diseases.

Pistacia lentiscus L. (PL) is a flowering plant traditionally used in the treatment of gastrointestinal disorders. The extracts of this plant are endowed with strong pharmacological activities. The aim of our current study was to investigate the anti-inflammatory and potential therapeutic effects of PL leaves aqueous extract (PLAE) against Dextran Sulfate Sodium (DSS)-induced acute colitis.

The therapeutic effect of PLAE was evaluated after orally administration of 3% DSS alone or concomitantly with PLAE (50, 100 or 200mg/Kg). Mucosal lesions were assessed by macroscopic and histopathological examination. In this context, hemorrhage, diarrhea, weight loss, and disease activity index (DAI) were determined daily throughout the experiment. In the same way, hematoxylin-eosin and Alcian blue staining of colonic mucosal were used to evaluate, respectively, mucosal damages and mucus production. Furthermore, the levels of nitric oxide (NO), and pro-inflammatory cytokines [tumor necrosis factor-α (TNF-α) and inter suggest that PLAE has beneficial effects and could constitute a promising approach against acute ulcerative colitis by targeting the deregulated immune response.

Our results showed that the systemic and local anti-inflammatory activities of aqueous leaves extract of PL improve the clinical signs of acute colitis. Our data suggest that PLAE has beneficial effects and could constitute a promising approach against acute ulcerative colitis by targeting the deregulated immune response.In the transition period between adolescence and young adulthood, individuals with 22q11.2DS are at an increased risk of developing severe psychiatric disorders. Various studies have focused on detecting risk factors, but until now protective factors are still understudied in 22q11.2DS. The current case-control study focuses on the role of resilience and quality of life (QoL) in young adults with 22q11.2DS and behavioural problems, in comparison with persons with an intellectual disability (ID) without a known genetic disorder. Self-report (and caregiver report) standardized questionnaires were used. Predictive general linear models were constructed to compare the resilience and quality of life across both groups (22q11.2DS vs ID-group) and to analyse the association between personal characteristics in both groups. Young adults with a 22q11.2DS show less resilience compared with both the general population norms and young adults with ID. Only a subscale of resilience (Acceptance of self and life) contributes to the reported level of QoL. link3 Reported health problems are not related to resilience, but have an important effect on QoL. Our results suggest different factors are underlying resilience and the relation with QoL in 22q11.2DS and ID in general. These factors deserve more research and are important to take into account in clinical practice.

Endoleaks after endovascular aortic aneurysm repair (EVAR) occur frequently with type 2 being the most common. Treatment of type 2 endoleaks is indicated if the aneurysmal sac increases in size.

In this case report, we will discuss a patient who presented with aneurysmal sac size increase 11 years after undergoing EVAR for an asymptomatic abdominal aortic aneurysm which extended into the iliac arteries. Multi-phase CT demonstrated an endoleak with features commonly seen in type 2 endoleaks; pooling of contrast near a lumbar artery orifice on the angiographic phase which increases during the delayed phase. Both internal iliac arteries were sacrificed during the initial EVAR. Percutaneous direct sac puncture was therefor performed and angiogram during the procedure revealed no feeding or draining lumbar arteries. During attempts to embolize the perfused part of the aneurysmal sac non-target embolization into the main body of the graft occurred and the presence of type 3b endoleak was confirmed. The non-target embolization did not result in permanent sequelae.
