Photoaffinity cross-linking of F1ATPase from spinach chloroplasts by 3'-arylazido-beta-alanyl-8-azido ATP.
1994
UV irradiation of the ATPase (CF1) from spinach chloroplasts in the presence of 3'-arylazido-beta-alanyl-8-azido ATP (8,3'-DiN3ATP) results in a nucleotide-dependent inactivation of the enzyme and in a nucleotide-dependent formation of alpha-beta cross-links. The results demonstrate an interfacial localization of the nucleotide binding sites on CF1.
Firmas zīmju atpazīšana un marķēšana attēlos un to tālāks pielietojums
2016
Maģistra darbs apraksta objektu atpazīšanas iespējas izmantojot video un attēlus. Darba ietvaros pirmajā nodaļā tika apskatītas pielietotās tehnoloģijas un populāri uzdevumi, kurus ar šīm tehnoloģijām iespējams risināt, kā arī attīstībā novērojamās tendences. Darba otrajā nodaļā apskatīti populāri jau esoši risinājumi ar kuru palīdzību no attēliem vai video jau tiek izgūta informācija, šie uzdevumi tie jau sen tiek pielietoti praksē. Aprakstīts to lietojuma princips un nepieciešamība. Darba trešajā nodaļā apskatīti dažādi interesanti sarežģītāki uzdevumi, kuros ir iespējams pielietot iepriekš apskatīto objektu atpazīšanas tehnoloģiju. Starp šiem uzdevumiem ir gan tādi, kuri jau tiek lietoti…
Preču zīmju meklēšana attēlos
2017
Šajā darbā tiek pētīta preču zīmju meklēšana attēlos. Trīs metodes, HOG, SIFT un SURF, tiek apskatītas tuvāk, notestētas un salīdzinātas savā starpā. Tā kā HOG metode uzrādīja vislabākos rezultātus, tai tika veikti nopietnāki testi, ar stipri lielāku attēlu kopu. Tika izpētīta iespēja padot HOG metodei dažādas attēla transformācijas, tādējādi ļaujot tai atpazīt arī pagrieztas un citādi transformētas preču zīmes. Iegūtie testēšanas rezultāti uz FlickrLogos-32 attēlu kopas, ļāva salīdzināt metodi ar citām modernajām metodēm. Kopumā HOG metode uzrādīja nedaudz sliktākus rezultātus par citām metodēm. No otras puses, metodes rezultāti joprojām ir konkurētspējīgi, ņemot vērā pielietošanas ērtumu …
Predictors of Participation and Autonomy in People With Multiple Sclerosis.
2019
Abstract Importance: Because multiple sclerosis (MS) affects many life areas, it is important to know how participation and autonomy are associated with the perceived impact of MS on everyday life. Objective: To investigate how perceived quality of life, disease impact, gender, and disease severity predict participation and autonomy in people with MS. Design: Cross-sectional study in which structural equation modeling was used to evaluate relationships between measured variables. Settings: Outpatient clinics in three areas and one inpatient rehabilitation center in Finland. Participants: Convenience sample of 194 people with MS. Outcomes and Measures: Participants completed the Impact on Pa…
Strategies for the recovery of patients with post stroke sequelae in the context of the COVID-19 pandemic
2020
Introduction. The performance areas of post-stroke mention negatively correlated determinants in doing daily activities. The intrinsic motor recovery depends on the primary motor deficit. The functional recovery of patients with post-stroke sequelae is not only based on the remission of the functional deficit, but it also depends on the ability to develop adapted motor strategies.The objective of the study was to point out, for the patients with post-stroke sequelae, the sensitive, motor and cognitive changes in the context of the COVID-19 pandemic. Material and method. The study included a number of 18 patients diagnosed with post-stroke sequelae and was conducted for a period of 5 months …
Energy-Linked Reactions Catalyzed by the Purified ATPase Complex (F0F1) from Rhodospirillum rubrum Chromatophores
1980
1. The isolation of the F0F1-ATPase complex from Rhodospirillum rubrum chromatophores by the use of taurodeoxycholate is described. 2. The enzyme preparation contains about 12 polypeptides; five are subunits of the F1 moiety. 3. The ATPase activity of the purified enzyme is dependent on the addition of phospholipids. 4. Km-vales for Mg2+-ATP and Ca2+-ATP are similar to the values obtained for the membrane-bound enzyme. 5. The F0F1-ATPase complex is more than 70% inhibited by oligomycin and N,N′-dicyclohexyl-carbodiimide. 6. The F0F1-ATPase complex was integrated into liposomes. The reconstituted proteoliposomes catalyzed energy transduction as shown by ATP-dependent quenching of acridine dy…
Capecitabine and irinotecan with and without bevacizumab for advanced colorectal cancer patients
2009
AIM: To investigate the efficacy and safety of cape-citabine plus irinotecan ± bevacizumab in advanced or metastatic colorectal cancer patients. METHODS: Forty six patients with previously untreated, locally-advanced or metastatic colorectal cancer (mCRC) were recruited between 2001-2006 in a prospective open-label phase II trial, in German community-based outpatient clinics. Patients received a standard capecitabine plus irinotecan (CAPIRI) or CAPIRI plus bevacizumab (CAPIRI-BEV) regimen every 3 wk. Dose reductions were mandatory from the first cycle in cases of > grade 2 toxicity. The treatment choice of bevacizumab was at the discretion of the physician. The primary endpoints were respon…
Efficacy and safety of irinotecan-based chemotherapy for advanced colorectal cancer outside clinical trials: an observational study.
2010
Background: This prospective observational study in typical community-based outpatient clinics evaluated the efficacy and toxicity of weekly and biweekly irinotecan-based chemotherapies and their compatibility depending on age. Methods: 601 patients with advanced or metastatic colorectal cancer receiving first-, second-, or third-line irinotecanbased therapy were regularly analyzed for response and toxicity until the end of therapy. Results: The median age was 65 (28–87) years, approximately one-third of the patients were ≥70 years old. Of all patients, 405 were treated weekly and 68 biweekly. Median overall survival (OS) for first-line therapy was 26.5 months for the <70-year-old patients …
Prevalence of elongation and calcification patterns of elongated styloid process in south india
2012
Objective: Very few studies have been reported in the literature classifying the elongation and calcification patterns of styloid process. The present study was done to investigate the prevalence of elongation and calcification patterns of styloid process in patients attending a dental institution in south India. Study design: 600 digital panoramic radiographs of patients with dental problems were obtained from the outpatient department of the Dental institution. The apparent length of the styloid process was measured by a single experienced oral radiologist, with the help of the measuring tools on the accompanying software. The type of elongation and calcification patterns of each elongate…
A comparison of the effects of ?-ketotriazole, MCPA and carbaryl on the plasma membrane Mg2+-ATPase activity and lipid composition of rice shoots (Or…
1993
The effect of γ-ketotriazole, MCPA and carbaryl on the lipid composition and ATPase activity associated with plasma membrane fractions from rice (Oryza sativa cv Bahia) shoots was investigated. With γ-ketotriazole and MCPA treatments the relative amount of δ5-avenasterol (%) was reduced in the plasma membrane, whereas with γ-ketotriazole a reduction was also found in the sitosterol content, expressed as a percentage of the total free sterol composition. The fatty acyl chain length of phosphatidylcholine fractions from MCPA-treated plants was also reduced. The plasma membrane Mg2+-ATPase activity was only stimulated in MCPA-treated plants. No changes were observed in lipid composition or ATP…
