Chronic low back pain (CLBP) is a multifactorial condition with a variety of symptoms; one being gait variability. The lumbar spine and its musculature are important in controlling gait and in CLBP the lumbar extensors are often deconditioned. Because of this specific exercise for the lumbar extensors is often recommended. It was therefore of interest to examine relationships between lumbar kin...

OBJECTIVES Exposure to organophosphorus (OP) pesticides, irreversible inhibitors of acetylcholinesterase (AChE), may result in long-lasting alterations in the functional state of the central nervous system. In earlier studies, we found that a single exposure of the rat to chlorphenvinphos (CVP), an OP pesticide, made the animal hyposensitive to amphetamine (AMPH) three weeks posttreatment. A re...

In the work environment, chemical stressors coexists frequently with physical or psychological stressors. The purpose of the present experiment was to find out whether the effects of a repeated exposure to chlorphenvinphos (CVP), an organophosphorus pesticide, could be modified by a concurrent exposure to restraint, a psychological stressor. The experiment was performed on male Wistar rats. CVP...

The hypothesis was tested that human cardiac filling pressures increase and the left atrium is distended during 20-s periods of microgravity (microG) created by parabolic flights, compared with values of the 1-G supine position. Left atrial diameter (n = 8, echocardiography) increased significantly during microG from 26.8 +/- 1.2 to 30.4 +/- 0.7 mm (P < 0.05). Simultaneously, central venous pre...

OBJECTIVES Effects of acute exposure to organophosphorous pesticides (OPs), chlorphenvinphos (CVP) or chlorphyriphos (CPF) on amphetamine (AMPH)- or scopolamine (SCOP)-induced open-field locomotion were compared in rats. MATERIALS AND METHODS CVP and CPF were administered intraperitoneally, both at doses resulting in about 50% inhibition of erythrocyte acetylcholinesterase (rbcAChE). The pest...

Recent isolation of the non-K1 Escherichia coli neonatal meningitis strain S286, belonging to phylogroup C, which is closely related to major group B1, and producing an extended-spectrum beta-lactamase, encouraged us to seek the genetic determinants responsible for its virulence. We show that S286 belongs to the sequence O type ST23O78 and harbors 4 large plasmids. The largest one, pS286colV (~...

BACKGROUND Hodgkin's disease (HD) after the age of 65 years is uncommon and there are no published data on chemotherapy regimens devised for elderly HD patients. PATIENTS AND METHODS From 1990 to 1993, 25 elderly HD patients were treated with the CVP/CEB regimen: chlorambucil 6 mg/sqm p.o. days 1 through 7, vinblastine 6 mg/sqm i.v. on day 1, procarbazine 100 mg/sqm p.o. days 1 through 7, pre...

Verbal protocols are widely used in user studies for evaluating websites. This study investigated the effectiveness and efficiency of concurrent and retrospective verbal protocols (CVP and RVP) for both blind and sighted participants, as well as participant workload and attitudes towards these methods. Eight blind and eight sighted participants undertook both protocols in a website evaluation. ...

The estimation of central venous pressure (CVP) by inspection of the neck veins is regarded as a quintessential example of effective bedside cardiovascular examination because it is virtually cost-free and requires minimal time and no equipment. In the upright position, venous drainage from the head occurs primarily through the vertebral veins, allowing the jugular vein to act as a manometer, “...
