To address these knowledge gaps, we examined relationships between granular measures of agricultural activity and lake total phosphorus (TP) and total nitrogen (TN) concentrations in 928 lakes and their watersheds in the Northeastern and Midwest U.S. using a Bayesian hierarchical modelling approach. We found that both lake TN and TP concentrations were related to these measures of agriculture, especially near-stream agriculture. The relationships between measures of agriculture and lake TN concentrations were more regionally variable than those for TP. Conversely, TP concentrations were more strongly related to lake-specific measures like depth and watershed hydrology relative to TN. Our finding that lake TN and TP concentrations have different relationships with granular measures of agricultural activity has implications for the design of effective and efficient policy approaches to maintain and improve water quality.Background & aims The aim of this study was to evaluate the feasibility, efficacy, and safety of removal and replacement of the same LAMS to facilitate DEN. Methods EUS-guided LAMS placement for WON was performed. During subsequent endoscopy for DEN, the LAMS was initially removed, DEN was performed, and the same LAMS was deployed across the transmural tract at the end of session. Results 140 LAMS were placed for PFC drainage (43 pseudocysts and 97 WON) from 10/1/2016 to 11/15/2019. Of these, 40 patients (mean age 43.88±15.35 years; 70% males; mean WON size 10.9±4.9 cm by 8.7±3.8 cm) underwent removal and replacement of the same LAMS for multiple DEN sessions. The. LAMS was successfully replaced across the transmural tract during all 81 DEN sessions. Complete resolution was achieved after a median of 2 (range 1-7; mean 2.4±1.5) DEN sessions with stent retrieval after a mean of 64.14±31.55 days after initial placement. There was no evidence of stent damage, tissue ingrowth or major bleeding. Conclusions Removal and replacement of LAMS during multiple necrosectomies is feasible, safe, and facilitates DEN.RT-qPCR requires an adequate choice of stably expressed reference genes for accurate normalization of mRNA expression. However, testing a panel of reference genes is often time-consuming and expensive. In this work, we aimed to develop a set of multiplex real-time PCR assays for RT-qPCR analysis of commonly used housekeeping genes in laboratory rats. Using Hydrolysis probe (TaqMan®) technology, we have designed and optimized three triplex qPCR assays (Actb + Gapdh + B2m; Rpl13a + Sdha + Ppia; Hprt1+Pgk1+Ywhaz) demonstrating optimal PCR amplification efficiencies (from 94.7 to 100.5%) and repeatability. Novel assays allow expression analysis of 9 reference genes in 3 reactions making possible a more time-efficient choice of reference genes in RT-qPCR experiments in Wistar rats in comparison with widespread singleplex assays.An understanding of the molecular mechanisms that underlie plant salt tolerance is important for both economic and scientific interests. Genome-wide Association Study (GWAS) is a promising approach to pinpoint genes that confer plant salt tolerance. With the advancement of supporting technology and methodology, GWAS has enabled the discovery of genes that play central roles in regulating plant salt tolerance in the past decade. Here I highlight recent successful GWAS work in unveiling the molecular factors underlying plant salt tolerance, and discuss the concerns and opportunities in conducting such experiments. It is anticipated that GWAS will be increasingly successful in the identification of key genes that are useful for crop improvement.Sporadic colorectal cancer (sCRC) is the third leading cause of cancer death in the Western world. Approximately, a quarter of sCRC patients present metastatic dissemination at the moment of diagnosis, the liver being the most frequently affected organ. Additionally, this group of CRC patients is characterized by a worse prognosis. In the last decades, significant technological developments for genome analysis have fostered the identification and characterization of genetic alterations involved in the pathogenesis of sCRC. However, genetic alterations involved in the metastatic process through which tumor cells are able to colonize other tissues with a different microenvironment, still remain to be fully identified. Here, we review current knowledge about the most relevant genomic alterations involved in the liver metastatic process of sCRC, including detailed information about the genetic profile of primary colorectal tumors vs. their paired liver metastases.Treating persistent neuropathic pain remains a major clinical challenge. Pifithrin-α Current conventional treatment approaches carry a substantial risk of toxicity and provide only transient pain relief. In this work, we show that the activity and expression of the inflammatory mediator secretory phospholipase-A2 (sPLA2) enzyme increases in the spinal cord after painful nerve root compression. We then develop phospholipid micelle-based nanoparticles that release their payload in response to sPLA2 activity. Using a rodent model of neuropathic pain, phospholipid micelles loaded with the sPLA2 inhibitor, thioetheramide-PC (TEA-PC), are administered either locally or intravenously at the time of painful injury or 1-2 days afterward. Local micelle administration immediately after compression prevents pain for up to 7 days. Delayed intravenous administration of the micelles attenuates existing pain. These findings suggest that sPLA2 inhibitor-loaded micelles can be a promising anti-inflammatory nanotherapeutic for neuropathic pain treatment.Background Acromegaly is an uncommon syndrome caused by growth hormone-producing pituitary adenoma or pituitary gland hypertrophy. Acromegaly is known to be characterized by progressive somatic disfigurement and a wide range of systematic manifestations. This case study describes a rare case of severe obstructive sleep apnea (OSA) caused by acromegaly. Clinical presentation A female patient presented to the consultant clinic with the chief complaint of progressively worsening sleep and was diagnosed with severe OSA. Because of a peculiar facial appearance of the patient, acromegaly was suspected and confirmed by the findings of hormonal analysis and magnetic resonance imaging (MRI). After transsphenoidal resection of the pituitary adenoma, her OSA was almost cured, with residual AHI of 5.5. Conclusion This case highlights the importance of a comprehensive clinical examination of OSA patients. In every sleep-related breathing disorder case, sleep clinicians should be aware of alternate problems that could cause upper airway obstruction.
