We evaluate the ability of an electronic nose to discriminate prostate cancer from benign prostatic hyperplasia using urine headspace, potentially offering a clinically applicable noninvasive and rapid diagnostic method.The ChemPro® 100-eNose was used sample headspace. Its performance tested with 50 patients confirmed 24 samples 15 (15 provided preoperatively 9 3 months postoperatively) scheduled undergo robotic assisted laparoscopic radical prostatectomy or transurethral resection prostate,...
Soft tissue infections, including postoperative wound result in a significant burden for modern society. Rapid diagnosis of infections is based on bacterial stains, cultures, and polymerase chain reaction assays, the results are available earliest after several hours, but more often not until days after. Therefore, antibiotic treatment administered empirically without specific diagnosis.We employed our electronic nose (eNose) system this proof-of-concept study, aiming to differentiate most...
Urinary tract infection (UTI) is a common disease with significant morbidity and economic burden, accounting for part of the workload in clinical microbiology laboratories. Current chemisty point-of-care diagnostics rely on imperfect dipstick analysis which only provides indirect insensitive evidence urinary bacterial pathogens. An electronic nose (eNose) handheld device mimicking mammalian olfaction that potentially offers affordable rapid samples without preparation at athmospheric...
Elevated concentrations of polyamines have been found in urine patients with malignant tumors, including ovarian cancer. Previous research has suffered from poorly standardized detection methods. Our liquid chromatography-tandem mass spectrometry (LC-MS/MS) method is capable simultaneous analysis most known polyamines. Liquid not previously used the differential diagnostics tumors postmenopausal women.In this prospective study, women (n = 71) presenting an adnexal and, as controls, genital...
Dog owners' understanding of the daily behaviour their dogs may be enhanced by movement measurements that can detect repeatable dog behaviour, such as levels activity and rest well changes. The aim this study was to evaluate performance supervised machine learning methods utilising accelerometer gyroscope data provided wearable sensors in classification seven typical activities a semi-controlled test situation. Forty-five middle large sized participated study. Two sensor devices were...
Background: The declining mortality rate of patients with colorectal cancer (CRC) can be explained, at least partially, early diagnosis. Simple diagnostic methods are needed to achieve a maximal patient participation in screening. Materials and Methods: Liquid chromatography electrospray tandem mass spectrometry (LC-MS/MS) was used determine urinary polyamine (PA) profiles. In prospective setting, 116 were included the study: 57 CRC, 13 inflammatory bowel disease (IBD), 12 adenoma, 34...
This study proposes a method for detecting the heartbeat intervals of person lying on bed from ballistocardiographic signals recorded unobtrusively with four dynamic force sensors located under posts. The does not recognize individual heartbeats, but where correlation between two consecutive signal segments maximizes. evaluated performance nine subjects in 1-h long recordings and achieved 91% beat-to-beat interval (BBI) recognition coverage; 98.6% detected BBIs differed less than 50 ms...
Movement sensor data from seven static and dynamic dog behaviors (sitting, standing, lying down, trotting, walking, playing, (treat) searching i.e. sniffing) was collected 45 middle to large sized dogs with six degree-of-freedom movement sensors attached the collar harness. With 17 collection procedure repeated. The duration of each approximately three minutes. order tasks varied between two repetitions (for dogs). were annotated post-hoc based on video recordings made camcorders during...
Due to new emission regulations, coverage of monitoring requirements extends boiler classes. In Europe, Industrial Emission Directive brings 15-50 MW boilers under the directive in special cases, so inexpensive NOx tools are appreciated. This paper presents models estimate two similar natural gas fired municipal hot water boilers. The utilize online process measurements also available relatively simple set-ups. context, performance linear regression model and nonlinear neural network...
The methods needed to interrogate passive resonance sensors are studied. A portable impedance measurement unit and the extract a coupling coefficient compensated frequency presented. interrogation demonstrated with ECG pressure measurements. results show that quality of signal measured flexible textile coil is sufficient heart rate. In case sensor, errors caused by changes in inductive were satisfactorily removed introduced method.
Dog owners are highly motivated in understanding behavior and physiology of their pets monitoring wellbeing. Monitoring with a commercially available activity trackers reveals levels daily rest but recognizing the dog would provide additional information, especially when is not under supervision. In this study, performance 3D accelerometer movement sensor placed on collar was evaluated classifying seven activities during semi-controlled test situation 24 dogs. Various features were extracted...
Aim: To determine whether an electronic nose can differentiate cultured nonmalignant and malignant prostatic cells from each other the smell print is secreted to surrounding medium. Materials & methods: Prostatic (EP-156T controls) (LNCaP) cell lines, as well conditioned unconditioned media, were collected. The prints of samples analyzed by a ChemPro® 100 device. data normalized dimension reduction was conducted. classified misclassification rates calculated. Results: differentiated lines...
Differential Mobility Spectrometry (DMS), also called as FAIMS is a variation of atmospheric pressure ion mobility measurement techniques and capable providing information about the electric field - dependence ions. In this method, combined used. This consists asymmetric oscillating high intensity low static component. Analytical in DMS 2-dimensional ionic current on amplitude value intensity. The signal for whole ranges both variables time consuming generates lot data. It disadvantage which...
In Finland, per-capita alcohol consumption increased in the early 2000s and decreased after 2007. Our aim was to determine how these changes originated from drinking practices.Repeated cross-sectional general-population surveys.Finland 2000, 2008 2016.Finnish residents aged 15-69 years (n = 6703, response rate 59-78%).Event-level data on occasions 21 097). Types of (drinking practices) were identified with latent class analysis using occasion characteristics. The aggregated volume...
Objective: To understand the contexts and characteristics of drinking occasions, we typologized occasions examined how different aspects vary in them what part population-level intoxication each covers. Method: A Finnish general population survey 2016 (n = 2,285) with event-level data on 6,697) was used. Occasion types were identified by latent class analysis. The location, purpose, company, timing, duration, amounts beverages drunk, estimated blood alcohol concentration (eBAC). Results:...
Polyamines play an important role in cellular proliferation, and the change polyamine metabolism is reported various cancers. We searched for urinary signature distinguishing between pancreatic cancer, premalignant lesions of pancreas (PLP), acute chronic pancreatitis, controls.Patients controls were prospectively recruited three Finnish hospitals October 2013 June 2016. The patients provided a urine sample at time diagnosis. panel 14 polyamines was obtained single run with mass...
