It is shown that for any full column rank matrix X 0 with more rows than columns there is a neighborhood [Formula: see text] of X 0 and a continuous function f on [Formula: see text] such that f(X) is an orthogonal complement of X for all X in [Formula: see text]. This is used to derive a distribution free goodness of…

AIM OF THE STUDY: To evaluate the results of surgical therapy of esophageal perforation in relation to the time of onset. METHODS: A retrospective study of patients records with a discharge diagnose of esophageal perforation RESULTS: During 12 years, 9 patients with esophageal perforation were treated at our surgical…

BACKGROUND: Early and excessive alcohol use is a significant threat to healthy development. Evidence supports the effectiveness of electronic alcohol interventions for young drinkers. However, effects are typically small and studies targeting under 18-year-olds are scarce. This trial is the first to evaluate the effect…

Many authors have reported on the use of the Unified Medical Language System (UMLS) to match concepts in free text. Unmatched search strings may be due to misspellings, concepts not in the UMLS, or searches for words not expected to be in the UMLS (e.g., names of people or places). We mapped search strings from a full-…

The Clinician's Workstation (CWS) has provided the full-functionality of an on-line electronic patient record for outpatient pediatric clinics over the past 3 years. The implementation of the CWS built upon a substantial effort in integration of data from various sources. This paper addresses the subsequent design issu…

Telemedicine (other than costly long distance telephone and facsimile messages) in the Federated States of Micronesia (FSM) started approximately 4 years ago with the establishment of Internet access in the State of Yap. A local access, for medical use only, via already established trunk lines maintained by Continental…

Hierarchical classification of biotechnology R&D projects is critical for strategic planning and national R&D resource allocation, yet remains challenging due to fine-grained hierarchical taxonomies, severe class imbalance, and the cost of large language model (LLM) inference at scale. We propose EnergyRoute, an uncert…

The concept of emergency medical transport originated from the need to move wounded soldiers from the battlefield to aid stations and other medical facilities (Ref. 11). Full Text (Free, PDF) www.bmj.sk.

UNLABELLED: The aim of the study was to compare the best corrected visual acuity (BCVA) before and at the 1st day after the cataract surgery for mature or the hard nuclear cataract. The phacoprobe NeoSoniX equipment Legacy (Alcon Laboratories) was used for the cataract surgery. Trypan blue for vital staining of the ant…

Disorders of haemostasis and haemocoagulation are often seen in patients with cancer as a part of paraneoplastic syndrome. Thrombotic and/or haemorrhagic complications are the second most common cause of mortality in patients with cancer. The evaluation of the haemostatic parameters of 67 patients with gastric cancer h…

UNLABELLED: The aim of this study is presentation of 3 cases reconstructive surgery of the skull base after craniocerebral injury. INJURIES AND METHODS: Extensive injuries of the skull base result in communication with paranasal cavities. DIAGNOSTICS: The most serious part of the operation is the isolation of the liq…

To investigate the role of potent MAO-B inhibitor deprenyl in fertilized females, we have evaluated the effect of chronic treatment with deprenyl at a low dosage on preimplantation embryo development in Wistar rats. We have found that the number of isolated embryos per rat did not differ between experimental and contro…

In a previous paper (Nie et al. in JHEP 1311:087, arXiv:1309.2204 [hep-th], 2013), we presented a holographic s [Formula: see text] p superconductor model with a scalar triplet charged under an SU(2) gauge field in the bulk. We also study the competition and coexistence of the s-wave and p-wave orders in the…

OBJECTIVE: We describe a working software technology that enables educators to incorporate their expertise and teaching style into highly interactive and Socratic educational material for distribution on the world wide web. MATERIALS/METHODS: A graphically oriented interactive authoring system was developed to enable…

BACKGROUND: Angiogenetic factors play an important role in the formation of new blood vessels involved in the growth and metastatic spread of solid tumors, but there is limited information regarding the clinical significance of serum bFGF levels in gastric cancer patients. PATIENTS AND METHODS: Serum bFGF concentratio…

The image depicts the covalent triazine frameworks reported in the manuscript for the sorption of COand also in metal-free catalysis. Read the full text…

BACKGROUND: The paper examines Co(II)-amino acid-imidazole systems (where amino acid = L-α-amino acid: alanine, asparagine, histidine) which, when in aqueous solutions, activate and reversibly take up dioxygen, while maintaining the structural scheme of the heme group (imidazole as axial ligand and Oupt…

OBJECTIVE: The aim of the presented study was to analyse the types and quantity of inquiries received at Drug Information Centre in Bratislava during the period from May 1997 to May 2006. The study analyses also the profile of the users of the latter centre with focus on the perception of drug risk, adverse drug reacti…

Objective. The aim of this study was to determine whether pregnancy increases the recurrence risk of cutaneous malignant melanoma (CMM) in women with a history of stage I CMM. Methods. The electronic medical databases of Medline and Embase were explored. All 1084 obtained articles were screened on title and abstract us…

India is becoming one of the hubs of clinical research. Commensurate with these advances, the government funding for biomedical research in thrust areas is also increasing. The Indian Council of Medical Research (ICMR), Department of Biotechnology (DBT), Department of Science and Technology (DST) are some of the govern…
