Recent decades have seen profound changes in species abundance and community composition. In the marine environment, the major anthropogenic drivers of change comprise exploitation, invasion by non-indigenous species, and climate change. However, the magnitude of these stressors has been widely debated and we lack empirical estimates of their relative importance. In this study, we focused on Eastern Mediterranean, a region exposed to an invasion of species of Red Sea origin, extreme climate change, and high fishing pressure...

To obtain selective and potent opioid receptor ligands, we synthesized dehydro derivatives of alvimopan and found compound (28f), a selective but modest affinity MOR antagonist, weaker than alvimopan (1). We replaced the aryl piperidine unit by an aryl piperazine to obtain the 1-(α-carboxycinnamyl)-4-arylpiperazines like (13h), which to our surprise had no MOR or DOR activity but was a KOR agonist with moderate affinity. In contrast, literature examples of aryl piperazines (4) and (5) were reported to be pan opioid receptor antagonists, while (6) was a MOR agonist...

BACKGROUND: Diagnosis of periprosthetic joint infection (PJI) remains a challenge despite a wide variety of available diagnostic tests. The question that arises is which of these tests has a better performance for diagnosing PJI. Diagnostic odds ratio (DOR) has been described as the best indicator for test performance. METHODS: To compare the performance of the standard diagnostic tests, the DOR of serum erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), synovial fluid (SF) white blood cell (WBC) count, SF polymorphonuclear (PMN%), and leukocyte esterase (LE) were calculated...

The involvement of heme oxygenase 1 (HO-1) in the modulation of the antinociceptive effects of opioids in type 1 diabetes has been demonstrated but the role played by the transcription factor Nrf2 in the regulation of painful neuropathy and in the effects and expression of δ-opioid receptors (DOR) in type 2 diabetes, has not been studied. In male BKS.Cg-m+/+Leprdb/J (db/db) mice, the anti-allodynic effects produced by a Nrf2 transcription factor activator, sulforaphane (SFN) administered alone and combined with two DOR agonists, [d-Pen(2),d-Pen(5)]-Enkephalin (DPDPE) and (+)-4-[(αR)-α-((2S,5R)-4-Allyl-2,5-dimethyl-1-piperazinyl)-3-methoxybenzyl]-N,N diethylbenzamide (SNC-80), were evaluated...

BACKGROUND: In the neonatal period, pituitary hormones including prolactin (PRL) and growth hormone (hGH) are secreted in high amounts due to immature feedback mechanisms. As both hormones are secreted in part by the same somatomammotrophic cells, we investigated their relationship in newborns in relation to sex, gestational week, method of delivery and anthropometric data. METHODS: Serum levels of PRL and hGH were measured in blood from 225 newborns. Newborn data were extracted from medical records...

Many studies manifested miRNA-100 was deregulated in various cancers, which indicated that miRNA-100 might be a potential biomarker of cancer diagnosis and prognosis. However, the role of miRNA-100 was still uncertain. We searched for qualified studies using PubMed, EMBASE, Web of Science, Cochrane library and CNKI databases. The diagnostic effect was evaluated by the pooled sensitivity, specificity, and other indexes. Pooled hazard ratios (HRs) with 95% confidence intervals (CIs) for overall survival (OS) were calculated to assess the prognostic value...

Electro-osmotically induced Joule heating in theta tips and its effect on protein denaturation were investigated. Myoglobin, equine cytochrome c, bovine cytochrome c, and carbonic anhydrase II solutions were subjected to electro-osmosis in a theta tip and all of the proteins were denatured during the process. The extent of protein denaturation was found to increase with the applied square wave voltage and electrolyte concentration. The solution temperature at the end of a theta tip was measured directly by Raman spectroscopy and shown to increase with the square wave voltage, thereby demonstrating the effect of Joule heating through an independent method...

Fever may be the only sign of a serious bacterial infection (SBI) in neonates. Ampicillin plus cefotaxime (A+C) and ampicillin plus gentamicin (A+G) are commonly used as empiric therapies for Escherichia coli, Group B Streptococcus (GBS) and Listeria monocytogenes, which are the most likely neonatal SBI pathogens (1). Culture-based screening and prophylaxis has significantly lowered GBS infections and an alarming increase in the antimicrobial resistance rates of Gram-negative bacteria, including cefotaxime and gentamicin resistance, has been reported (1-3)...

The Valve Academic Research Consortium-2 recommends cutoff levels of cardiac troponin of >15 and of creatine kinase MB (CKMB) of >5 of the upper limit of normal (ULN) as markers of periprocedural myocardial infarction. We aimed to evaluate the correlation of these cutoffs with the survival rate in patients who underwent transcatheter aortic valve implantation (TAVI) through the femoral access. Patients who underwent TAVI were classified according to the postprocedural peak marker level of >15 and >5 ULN for troponin and CKMB, respectively...

BACKGROUND: The post mortem examination or autopsy is a trusted method of identifying the cause of death. Patients and their families may oppose an autopsy for a variety of reasons, including fear of mutilation or owing to religious and personal beliefs. Imaging alternatives to autopsy have been explored, which may provide a viable alternative. OBJECTIVE: To explore the possibility of using MRI virtopsy to establish the cause of death as an alternative to the traditional post mortem examination or autopsy...

Widespread pain and anxiety are commonly reported in cancer patients. We hypothesize that cancer is accompanied by attenuation of endogenous opioid-mediated inhibition, which subsequently causes widespread pain and anxiety. To test this hypothesis we used a mouse model of oral squamous cell carcinoma (SCC) in the tongue. We found that mice with tongue SCC exhibited widespread nociceptive behaviors in addition to behaviors associated with local nociception that we reported previously. Tongue SCC mice exhibited a pattern of reduced opioid receptor expression in the spinal cord; intrathecal administration of respective mu (MOR), delta (DOR), and kappa (KOR) opioid receptor agonists reduced widespread nociception in mice, except for the fail flick assay following administration of the MOR agonist...
