his severe disease state.Pyrolysis liquids are the main products in biomass pyrolysis, and the strong acidity limits its utilization. selleck Likewise, activators are required in the process of preparing biomass-based activated carbon, and current activators are usually chemical agents and not sustainable. Both issues are addressed with the new concept of using acidic pyrolysis liquids as the activator of biomass-based activated carbon. In the present research, corncob-based activated carbon was prepared with phosphoric acid and pyrolysis liquids (bio-oil and wood vinegar) as activators. The effects of activation temperature and the types of activators on the structure and surface chemical properties of activated carbon were investigated. Results show that the adsorption performance and specific surface area of activated carbon prepared with bio-oil are not as good as that prepared with phosphoric acid and wood vinegar, but its yield is relatively high. Some alkali and earth alkaline metals remain on the activated carbon prepared by bio-oil and wood vinegar. At 450 °C, the surface area and pore volume of activated carbon prepared with bio-oil and wood vinegar were much smaller than the ones prepared with phosphoric acid. Increasing the activation temperature may improve the performance of activated carbon. The specific surface area of activated carbon prepared with wood vinegar as the activator can reach 384.35 m2/g at an activation temperature of 850 °C, which is slightly inferior to that prepared with phosphoric acid as the activator. However, the adsorption amount of methylene blue exceeds the activated carbon prepared with phosphoric acid. This shows that wood vinegar can be used as an activator to prepare biomass-based activated carbon to achieve sustainability of the entire preparation process of biomass-based activated carbon.

White sturgeon iridovirus (WSIV) disease is caused by a virus of the eponymous family and is mostly triggered by stressful environmental conditions,

. high rearing density, excessive handling, or temporary loss of water. The aim of this study was to develop the most effective diagnostic method for quick and efficient confirmation or exclusion of the presence of WSIV.

A total of 42 samples (spleen, gills, intestine, skin, kidney, and brain) were collected from eight sturgeon (

and

) aged ≤5+ farmed or caught between 2010 and 2014 in open waters (Dąbie Lake and Szczecin Lagoon). They were tested for WSIV presence using conventional PCR, qPCR, and

hybridisation (ISH).

In gross examination, all fish appeared to be healthy. Neither species showed clinical signs typical of WSIV infection. In the majority of cases, fragments of iridoviral DNA were found using molecular methods in the kidneys, and also in the liver, gills, and skin. The detection rate using ISH was 47.37% and most commonly the brain and kidney tissues were positive. The most efficient of the methods used was real-time PCR, with 100% effectiveness in detection of WSIV DNA.

The study demonstrates the capabilities for WSIV diagnosis available to sturgeon farmers and water administrators, indicating useful methods of adequate sensitivity as well as organs to sample in order to achieve the highest probability of viral detection.

Both clinical suspicion and diagnosis of pheochromocytoma (PCC) can be challenging in patients where the presentation can be confused with the pharmacophysiological effects of illicit drugs known to activate the sympathetic nervous system. We report on such a patient and outline considerations that can impact diagnostic decision making.

Clinical examination, measurement of plasma metanephrines, followed by magnetic resonance imaging, iodine 123-metaiodobenzylguanidine single-photon emission computed tomography, and histopathology of the resected tumor.

A 35-year-old male patient was referred to our center because of a right-sided adrenal mass, incidentally found during an abdominal ultrasound performed due to nausea, vomiting, and lumbar pain. Although he had no history of hypertension, he had complained for over 6 years of severe episodic headache, panic attacks, and profuse sweating. He also had a longer history of methamphetamine abuse. Plasma concentrations of metanephrine (10.7 pmol/L) and normetanephrine (3.83 pmol/L) were 25-fold and 5.6-fold above respective upper limits of reference intervals (0.42 and 0.69 pmol/L). This indicated a PCC, which was confirmed after adrenalectomy. Failure to recognize the patient's signs and symptoms as attributable to a PCC was unsurprising given that methamphetamine abuse can result in many of the same signs and symptoms as a catecholamine-producing tumor.

The abuse of drugs such as methamphetamine can obscure an underlying PCC due to the similarity of several symptoms associated with both conditions. Recognition of a PCC in patients using illicit drugs such as methamphetamine remains challenging.

The benefits of physical activity (PA) for people with cystic fibrosis (pwCF) are widely accepted, yet how PA is promoted and utilised by pwCF is unclear.

An online questionnaire to explore attitudes, practices and promotion of PA in cystic fibrosis was completed by healthcare providers (HCP), pwCF and parents/caregivers.

351 respondents (105 HCP, 120 pwCF, and 126 parents/caregivers) from 12 countries completed the survey. Importance of PA was rated highly by the majority of respondents. Physical (

health), psychological (

enjoyment) and social (

social interaction) factors were motives for PA for 82%, 49% and 37% of pwCF, respectively, irrespective of country. Common barriers to PA included time (49% and 36%) and tiredness (61% and 7%) for pwCF and parents/carers, respectively. pwCF also reported psychosocial barriers (

stigma, demoralisation), while parents/caregivers reported structural barriers (

cost). Clinical teams varied substantially in terms of the emphasis placed on PA, facilities available, staff and training, and advice given to pwCF.
