Article Synopsis
  • The study explores a new method using quartz powder to break down microalgal cells to improve methane production.
  • A two-phase cultivation process with nitrogen deprivation and salinity changes was applied to two types of algae, enhancing their biochemical potential.
  • Mechanical disruption led to significant increases in methane yield, with Chlorella vulgaris producing 305 mL CH/g volatile solids and Monoraphidium contortum producing 324 mL CH/g VS, marking improvements of 51% and 86%, respectively.

The qualitative experience of sickness and death matters. Modern medicine has made important strides in addressing physical-and to some extent psychological-suffering at the end of life, but biomedical models are not properly equipped to respond to spiritual distress. Medical professionals and spiritual care professionals have an obligation, grounded in the bioethical principle of beneficence, to address all forms of suffering and to advocate for better dying.

Testicular incidentalomas are non-palpable, asymptomatic lesions, most frequently detected on ultrasound examinations. Each incidentaloma should undergo a standardized diagnostic workup to exclude malignancy and recognize other potentially significant non-malignant conditions that may first present with an incidental finding on scrotal ultrasound. This position statement of the World Federation of Ultrasound in Medicine and Biology (WFUMB) summarizes the available evidence on management of testicular incidentalomas and describes efficient management strategies with particular reference to the role of ultrasound techniques.

The aim of the study was to evaluate the effect of herbicidal ionic liquids on the population changes of microorganisms used in a batch anaerobic digester. The influence of the following ionic liquids: benzalkonium (2,4-dichlorophenoxy)acetate (BA)(2,4-D), benzalkonium (4-chloro-2-methylphenoxy)acetate (BA)(MCPA), didecyldimethylammonium (2,4-dichlorophenoxy)acetate (DDA)(2,4-D), didecyldimethylammonium (4-chloro-2-methylphenoxy)acetate (DDA)(MCPA), as well as reference herbicides (4-chloro-2-methylphenoxy)acetic acid (MCPA) and (2,4-dichlorophenoxy)acetic acid (2,4-D) in the form of sodium salts on biogas production efficiency was investigated. The effective concentration (EC50) values were determined for all tested compounds.

Composting of poultry manure which is high in N and dense in structure can cause several problems including significant N losses in the form of NH through volatilization. Biochar due to its recalcitrance and sorption properties can be used in composting as a bulking agent and/or amendment. The addition of a bulking agent to high moisture raw materials can assure optimal moisture content and enough air-filled porosity but not necessarily the C/N ratio.

Polyacrylamide (PAM) used in sludge dewatering exists widely in high-solid anaerobic digestion. Acrylamide is registered in the list of chemicals demonstrating toxic, carcinogenic and mutagenic properties. Therefore, it is reasonable to ask about the mobility of such residual substances in the environment.

Adolescence is a time period when major changes occur in the brain with long-term consequences for behavior. One ramification is altered responses to drugs of abuse, but the specific brain mechanisms and implications for mental health are poorly understood. Here, we used a mouse model in which adolescents display dramatically reduced sensitivity to the acute locomotor stimulating effects of cocaine and methamphetamine.

On the 25th anniversary of the American Association for Women Radiologists (AAWR), the association's accomplishments in promoting the careers of women radiologists were reviewed. Programs that feature opportunities for women to balance their careers and their personal lives have contributed greatly to promoting networking opportunities at national meetings. Highlights of women's accomplishments in national radiology organizations underline how far women have advanced in the specialty.

Aim: The aim of the present study was to assess the safety and efficacy of percutaneous coronary interventions (PCI) using the new Polish stent "Chopin" (Balton, Poland).

Methods: The study consisted of experimental and clinical parts. In the experimental phase, the new stent was implanted into 5 pigs and control coronary angiography as well as intracoronary ultrasonography (ICUS) were performed 30 days later.

In the article by Schatzki published in 1963, data about the lower esophageal ring relate ring diameter to presence of dysphagia. Statistical analysis of these measurements was performed to quantify conclusions of Schatzki and to extract additional information from the data. Ring diameters in 332 patients with and without dysphagia are described in a histogram in the original article of Schatzki.

Unlabelled: The recurrent stenosis of previously successfully dilated coronary arteries still remains a matter of concern despite of the improved short and long term results of percutaneous coronary angioplasty. The role of dyslipidaemia in the origin of restenosis after coronary angioplasty is still controversial. The aim of our study was to evaluate the efficacy of hypolipemic treatment in patients undergoing coronary angioplasty and to find out whether successful lowering of lipid parameters to normal limits is related to improvement exercise capacity and systolic function of left ventricle.

Hemodynamic changes related to pregnancy in women with Congenital Heart Disease (ConHD) or Acquired Valvular Heart Disease (AVHD) require special medical care during pregnancy and especially immediately prior to, and after delivery. Following a five year retrospective study (1978-1982), the authors monitored prospectively over a period of 12 years (1983-1994), 378 pregnancies in 252 women with ConHD and AVHD. Based on the results of the initial clinical examination and monthly follow-up visits, a numerical risk score was assigned for each patient.

In 40 patients with unstable angina pectoris a variety of electrocardiographic parameters were analysed. In all patients routine ECG, signal averaged high resolution ECG. 24 hour ECG recordings and heart rate variability analysis were performed at admission and repeated at 7 day of hospitalization.

In 82 patients with unstable ischemic heart disease (IHD) before and after revascularisation (percutaneous transluminal coronary angioplasty-PTCA-in 11 patients and coronary artery bypass graft-CABG-in 71 patients) silent ischemia incidence was observed. In these patients before and after operation election fraction (EF) and wall motion score index (IK) were compared echocardiographically as well as physical ability according to Bruce protocol in treadmill exercise test. Data (EF and IK and exercise test) before and after operation didn't change significantly.
