Prognostic value of systolic ankle and toe blood pressure levels in outcome of diabetic foot ulcer

The prognostic value of distal blood pressure measurements has been studied in 314 consecutive diabetic patients with foot ulcers. Systolic toe blood pressure was measured with a strain-gauge technique, and ankle pressure was measured with strain-gauge or Doppler techniques. Wound healing was defined as intact skin for at least 6 mo. One hundred ninety-seven patients healed primarily, 77 had amput

Hepatitis C virus and GB virus C/hepatitis G virus viremia in Swedish blood donors with different alanine aminotransferase levels

BACKGROUND: Hepatitis C virus (HCV) is a known blood-borne hepatotropic virus for which antibody screening of blood donors is universally practiced. The newly identified GB virus C (GBV-C) and its strain variant hepatitis G virus (HGV) are of unknown pathogenic significance, and screening of blood donors for this agent has not yet been implemented. Polymerase chain reaction (PCR) is the most sensi

First stars IV. CS 29497-030: Evidence for operation of the s-process at very low metallicity

We present an abundance analysis of the very metal-poor, carbon-enhancedstar CS 29497-030. Our results indicate that this unusually hot turnoffstar (Teff = 6650 K, log g = 3.5) has a metallicity [Fe/H] =-2.8, and exhibits large overabundances of carbon ([C/Fe] = +2.38),nitrogen ([N/Fe] = +1.88), and oxygen ([O/Fe] = +1.67). This star alsoexhibits a large enhancement in its neutron-captu

Low systolic blood pressure is associated with impaired cognitive function in the oldest old: longitudinal observations in a population-based sample 80 years and older

Background and aims: The primary aim of the present study was to examine whether there is an association between blood pressure and the risk of subsequent cognitive decline in the oldest old. Various factors associated with blood pressure and cognitive function were considered. Methods: The study comprised 599 individuals of a population-based sample, 199 men (mean age at baseline 82.8 years, rang

Role of stray light in the formation of high-resolution resonant photoelectron spectra: an experimental and theoretical study of N-2

We show that the undular stray light, diffusely scattered by the optical system of a synchrotron beamline, can play an important role in the formation of high-resolution resonant photoelectron (RPE) spectra. The influence of the stray light is mediated through the Stokes doubling effect, with the Lorentzian tail of the spectral function being replaced by a more complicated form. This effect is sho

Photodynamic Therapy utilizing Interstitial Light Delivery Combined with Spectroscopic Methods

Popular Abstract in Swedish Redan för 5000 år sedan i det antika Egypten användes ljus för att behandla vissa hudåkommor. Denna bortglömda kunskap återupptäcktes i början av förra seklet men fick inget riktigt genomslag. De senare årtiondenas framsteg inom kemi och fysik har återigen gjort ljusbehandling av sjukdomar högintressant. Speciellt upptäckten av lasern på 1960-talet har gjort att tillämpSince cancer continues to plague humanity there is large need for development of modalities for both diagnosis and therapy. Most of the currently available methods suffer from serious disadvantages. The treatments, e.g. ionising radiation, chemotherapy, surgery, may themselves induce malignancies or the patient may be physically impaired for a longer period of time. The work presented aims at dev

HAMLET kills tumor cells by an apoptosis-like mechanism--cellular, molecular, and therapeutic aspects.

HAMLET (human α-lactalbumin made lethal to tumor cells) is a protein-lipid complex that induces apoptosis-like death in tumor cells, but leaves fully differentiated cells unaffected. This review summarizes the information on the in vivo effects of HAMLET in patients and tumor models, on the tumor cell biology, and on the molecular characteristics of the complex. HAMLET limits the progression of hu

Human alpha-lactalbumin made lethal to tumor cells (HAMLET) kills human glioblastoma cells in brain xenografts by an apoptosis-like mechanism and prolongs survival.

Malignant brain tumors present a major therapeutic challenge because no selective or efficient treatment is available. Here, we demonstrate that intratumoral administration of human α-lactalbumin made lethal to tumor cells (HAMLET) prolongs survival in a human glioblastoma (GBM) xenograft model, by selective induction of tumor cell apoptosis. HAMLET is a protein-lipid complex that is formed from α

Present and new techniques and devices in the treatment of DFU: a critical review of evidence

Management of foot ulcer in individuals with diabetes remains a major therapeutic challenge throughout the world. We performed a critical review of evidence of present and new techniques and devices in the treatment of diabetic foot ulcer. The golden standard for optimal evidence in the Cochrane system is level I randomized controlled trials, and meta-analyses of several randomized controlled tria

Encouraging primary care research: evaluation of a one-year, doctoral clinical epidemiology research course.

Research and PhDs are relatively rare in family medicine and primary care. To promote research, regular one-year research courses for primary care professionals with a focus on clinical epidemiology were started. This study explores the academic outcomes of the first four cohorts of research courses and surveys the participants' perspectives on the research course. An electronic survey was sent to

Risk Identification on the Interface Between Business Case and Requirements

Motivation: The requirements engineering (RE) research community is aware of the importance of performing feasibility studies before starting requirements elicitation. Unfortunately, projects still frequently fail to achieve commercial success, responsibility is often unknown, and requirements engineers may be deemed responsible for mistakes made by others. Problem: There is neither empirical evid

DFL23448, a novel TRPM8-selective ion channel antagonist, modifies bladder function and reduces bladder overactivity in awake rats.

The transient receptor potential (TRP) melastin 8 ion channel (TRPM8) is implicated in bladder sensing but limited information on TRPM8 antagonists in bladder overactivity (BO) is available. This study characterizes a new TRPM8-selective antagonist (DFL23448) and evaluates it in cold-induced behavioral tests and on bladder function and experimental BO in vivo in rats. DFL23448 displayed IC50 value

A web-based prognostic tool for extremity and trunk wall soft tissue sarcomas and its external validation

BACKGROUND: We developed a web-based, prognostic tool for extremity and trunk wall soft tissue sarcoma to predict 10-year sarcoma-specific survival. External validation was performed. METHODS: Patients referred during 1987-2002 to Helsinki University Central Hospital are included. External validation was obtained from the Lund University Hospital register. Cox proportional hazards models were fitt

Effect of rFVIIa dose and time to treatment on patients with haemophilia and inhibitors: analysis of HemoRec registry data from the Czech Republic

Identifying haemophilia patients with inhibitors for clinical trials is difficult due to the limited number of patients available. Registries are therefore being established as an additional means of data collection. The aim of this study was to investigate the effect of different recombinant activated factor VII (rFVIIa; NovoSeven((R))) dose ranges and dosing schedules on the incidence of re-blee

Boundary layer control on convective available potential energy: Implications for cumulus parameterization

[1] Convective available potential energy (CAPE), frequently regarded as an indicator of the potential intensity of deep convection, is strongly controlled by the properties of the planetary boundary layer (BL). Variations in CAPE observed during field experiments in midcontinent North America, the tropical east Atlantic, and the tropical west Pacific, can be accounted for mostly by changes in the

Genomewide linkage analysis of stature in multiple populations reveals several regions with evidence of linkage to adult height

Genomewide linkage analysis has been extremely successful at identification of the genetic variation underlying single-gene disorders. However, linkage analysis has been less successful for common human diseases and other complex traits in which multiple genetic and environmental factors interact to influence disease risk. We hypothesized that a highly heritable complex trait, in which the contrib

Blood-brain barrier permeability following traumatic brain injury.

BACKGROUND: Brain edema and intracranial hypertension is deleterious after traumatic brain injury (TBI), but the underlying pathophysiology is complex and poorly understood. One major subject of controversy is the time course and extent of blood-brain barrier (BBB) dysfunction following trauma, and previous studies in humans have only provided semi-quantitative data. The objective of the present s

Cancer of unknown primary is associated with diabetes.

The incidences of both type 1 diabetes (T1D) and T2D are increasing worldwide. T2D is associated with many cancers. However, no data are available on cancer of unknown primary (CUP), a relatively common, fatal cancer for which tobacco smoking is the only known risk factor. At diagnosis, CUP metastases are found in various organs, which has implications for prognosis. We carried out a nationwide st

Assessment of interactions between 205 breast cancer susceptibility loci and 13 established risk factors in relation to breast cancer risk, in the Breast Cancer Association Consortium

Background: Previous gene-environment interaction studies of breast cancer risk have provided sparse evidence of interactions. Using the largest available dataset to date, we performed a comprehensive assessment of potential effect modification of 205 common susceptibility variants by 13 established breast cancer risk factors, including replication of previously reported interactions. Methods: Ana

Management of Advanced Therapies in Parkinson's Disease Patients in Times of Humanitarian Crisis : The COVID-19 Experience

Background: Although the COVID-19 pandemic is affecting a relatively small proportion of the global population, its effects have already reached everyone. The pandemic has the potential to differentially disadvantage chronically ill patients, including those with Parkinson's disease (PD). The first health care reaction has been to limit access to clinics and neurology wards to preserve fragile pat
