INTRODUCTION: Data on human atrial repolarization are scarce since the QRS complex normally obscures its ECG trace. In the present study, consecutive patients with third-degree AV block were studied to better describe the human Ta wave. METHODS AND RESULTS: Forty patients (mean age 75 years, 17 men) were included. All anti-arrhythmic drugs were discontinued before ECG recording. Standard 12-lead E
BACKGROUND: /st> Septic shock includes blood vessel dilatation and activation of innate immunity, which in turn causes release of antimicrobial peptides such as LL-37. It has been shown that LL-37 can attract leucocytes via the lipoxin A(4) receptor (ALX, FPRL1). ALX is also present in vascular endothelial cells. To explore possible ways of pharmacological intervention in septic shock, we investig
OBJECTIVES: The purpose of the study was to assess the effect of exposure to presistent organochlorine compounds through the consumption of fatty fish from the Baltic Sea on human fertility. METHODS: Information on time to pregnancy, miscarriages, and subfertility was collected retrospectively by self-administered questionnaires in two cohorts of fishermen's sisters from the Swedish east coast, by
BACKGROUND: It is not always feasible to use standard electrode placement for limb leads when recording the 12-lead electrocardiogram (ECG). Other electrode placements have been accepted during monitoring. Nonstandard electrode positions, however, fail to produce waveforms identical to those recorded from the distal limb positions that are standard for diagnostic interpretation. The purpose of the
PURPOSE An overwhelming majority of data on familial risk in cancer is based on incident cancer, whereas familiality in cancer mortality is largely unknown. If fatal form of cancer was a highly familial subtype, then familial risk for mortality may exceed that of incidence, which would be particularly relevant for clinical decision making and counseling. PATIENTS AND METHODS The individuals in the
Abstract in UndeterminedThere are numerous of challenges confronting social work with older people. In Sweden, this is scarcely discussed, which is interesting in light of the radical organisational change in 1992, when all eldercare became a municipal responsibility governed by the Social Service Act. At this point in time, a decisive change was also introduced in England. The legislative changes
Recurrent spontaneous abortion (RSA), three or more pregnancy losses prior to 20 weeks, occurs in about 1% of all pregnancies, 50% of RSA cases remain unexplained and unresolved. Recently, immune pathways have been implicated in the pathophysiology of RSA. Immune tolerance of the fetal-placental unit and placental angiogenesis are mandatory for a successful pregnancy outcome. Unscheduled dysregula
Density functional theory was employed to investigate the adsorption site and hyperfine interactions of nitric oxide adsorbed in Na-LTA (previous name NaA) zeolite. Three different cluster models of increasing complexity were used to represent the zeolite network: (1) a six-membered ring terminated by hydrogen atoms with one sodium ion above the ring, (2) as model 1 with the addition of three sodi

Fluence-response relationships for the enhancement of ultraweak luminescence by UV radiation were determined in leaves of Brassica napus L. (cv. Ceres) when either the adaxial or abaxial leaf surface was exposed to monochromatic radiation (270–340 nm). Action spectra for both leaf surfaces were constructed from the fluence-response curves at the fluence required to obtain a doubling of the ultrawe

Objective: The objective was to determine the glycaemic index (GI) and insulinaemic index (II) of some common products intended for infants; that is, three commercial porridges and one gruel. Also, the influence of added fruit components to porridge on postprandial metabolic responses was studied by comparing corresponding data with a matched model product without fruit. Design: The volunteers wer
Sixty-six patients operated on for isolated cleft palate were evaluated as adults, and their speech was assessed clinically. Forty-four had undergone a von Langenbeck repair at the age of 7 months and 22 a Wardill repair at the age of 18 months. Speech was judged subjectively by the patients themselves, and perceptual assessment was made by three speech pathologists. The remaining speech problems,
Objective: Lately, desmopressin (dDAVP) administered orally has been demonstrated to be an effective alternative in the management of nocturia in adults. Although the safety profile of dDAVP is well known, much of the experience originates from studies in enuretic children and younger adults, and it may not be readily extrapolated to elderly patients. In order to identify factors associated with a
