Effect of Number of Home Exercises on Compliance and Performance in Adults Over 65 Years of Age

Field: Health Professions (Health Sciences)

Abstract Background and Purpose. There is limited research on the effects of the number of exercises a person is told to perform on compliance and performance, as defined by cueing requirements, correct alignment, and quality of movement. Some studies of medication suggest that compliance decreases as the number of medications increases. The purpose of this study was to determine whether older adults comply and perform better (ie, requiring less cueing, exhibiting correct alignment, and exhibiting controlled, coordinated, and continuous movements) when they are asked to do 2, 5, or 8 exercises. Subjects. Subjects were 11 women and 4 men, aged 67 to 82 years (X̄=72.8), who were living independently in their communities. Methods. Subjects were randomly prescribed 2, 5, or 8 general strengthening home exercises. They were instructed on their exercises at an initial session and asked to record the number of repetitions performed each day in a self-report exercise log. At a return session 7 to 10 days later, subjects were scored on their performance of the prescribed exercises using a newly designed assessment tool. Results. The group that was prescribed 2 exercises performed better, as defined by their performance tool score, than the group that was prescribed 8 exercises. The group that was prescribed 5 exercises was not different from the groups that performed 2 or 8 exercises. No differences were found among groups regarding the self-report measurement of compliance. There was a moderate correlation between performance scores and the self-report percentage rates. Conclusion and Discussion. Subjects who were prescribed 2 exercises performed better than subjects who were prescribed 8 exercises. The question of an optimal number of exercises to prescribe to elderly people warrants further study.

Correlation and path coefficient analysis for growth, yield and quality traits in pumpkin (Cucurbita moschata Duch. ex. Poir)

Field: Agricultural and Biological Sciences (Life Sciences)

The present investigation was carried out with aims to assess the correlation and path coefficient analysis. The observations were recorded on parents and F1’s for twenty quantitative traits including six quality traits viz., node number to first male flower appearance, node number to first female flower appearance, days to first male flower anthesis, days to first female flower anthesis, days to first fruit harvest, vine length (m), inter nodal length (cm), number of primary branches per plant, fruit weight (kg), number of fruits per plant, equatorial circumference of fruit (cm), polar circumference of fruit (cm), flesh thickness (cm), fruit yield per plant (kg), and six quality/biochemical traits namely ascorbic acid, reducing sugars (%) non-reducing sugars (%), total sugars (%), dry matter content and total soluble solids. The most important trait fruit yield per plant had exhibited significant and positive phenotypic correlation with number of fruits per plant, average fruit weight, total soluble solids, vine length, flesh thickness, ascorbic acid content, total sugars, number of primary branches per plant, equatorial circumference of fruit and negative significant association with days to first male flower anthesis, days to first female flower anthesis, days to first fruit harvest, inter nodal length and node number to first male flower appearance at phenotypic level. Analysis of path coefficient revealed that the highest positive direct effect on fruit yield per plant was exerted by number of fruit per plant followed by vine length at phenotypic level. Whereas, highest positive indirect effect exhibited on fruit yield per plant. The analysis of variance for combining ability revealed that there were significant differences for all the traits.
Contributions of O Island 48 to Adherence of Enterohemorrhagic Escherichia coli O157:H7 to Epithelial Cells In Vitro and in Ligated Pig Ileal Loops

Field: Immunology and Microbiology (Life Sciences)

ABSTRACT O island 48 (OI-48) of Escherichia coli consists of three functional gene clusters that encode urease, tellurite resistance (Te r ), and putative adhesins Iha and AIDA-1. The functions of these clusters in enterohemorrhagic E. coli (EHEC) O157:H7 infection are unknown. Deletion mutants for these three regions were constructed and evaluated for their ability to adhere to epithelial cells in vitro and in ligated pig ileal loops. Deletion of the Te r gene cluster reduced the ability of the organism to adhere to and form large clusters on IPEC-J2 and HEp-2 cells. Complementation of the mutation by introducing the wild-type ter genes restored adherence and large-cluster formation. Tests in ligated pig ileal loops showed a decrease in colonization by the Te r -negative mutant, but the difference was not significant compared to colonization by the wild type (26.4% ± 21.2% versus 40.1% ± 19.1%; P = 0.168). The OI-48 aidA gene deletion had no effect on adherence in vitro or in vivo. Deletion of the iha and ureC genes had no effect on adherence in vitro but significantly reduced the colonization of EHEC O157:H7 in the ligated pig intestine. These data suggest that Te r , Iha, and urease may contribute to EHEC O157:H7 pathogenesis by promoting adherence of the pathogen to the host intestinal epithelium.
Dietary intake of vitamin K and risk of incident and fatal myocardial infarction in the EPIC-Heidelberg cohort study

Field: Medicine (Health Sciences)

Background: The vitamin K-dependent Matrix-Gla-protein (MGP) has been shown to inhibit vascular calcification. Few prospective studies have been conducted relating habitual dietary vitamin K intake to the risk of coronary events. We investigated the association between phylloquinone (vitamin K1) and menaquinones (vitamin K2) intake and the risk incident and fatal myocardial infarction (MI) in the Heidelberg cohort of the European Prospective Investigation into Cancer and Nutrition (EPIC). Methods: The study was conducted in 23,464 EPIC-Heidelberg participants aged 35–64 years and free of prevalent coronary heart disease at enrolment 1994–1998. Dietary vitamin K intake was estimated from food frequency questionnaires completed at baseline using HPLC-based food composition data. Hazard ratios (HR) and 95% confidence intervals (CI) adjusted for lifestyle (smoking, body mass index, waist circumference, hypercholesterolemia, high blood pressure, aspirin use, physical activity, and education) and dietary (energy, fat, alcohol, calcium, and folate intake) factors associated with coronary heart disease were estimated using Cox proportional hazards models. Results: Between recruitment and March 2009, 420 incident events of MI occurred, of which 98 were fatal. Dietary intake of phylloquinone was not associated with incident MI (HR comparing highest versus lowest quartile was 0.87, 95% CI 0.64–1.18, p-trend=0.44), but inversely associated with fatal MI (HR 0.49, 95% CI 0.25–0.94, p-trend=0.03). The inverse association with fatal MI persisted after additional adjustment for vegetable intake. Dietary intake of menaquinones was not associated with incident (HR 1.21, 95% CI 0.81–1.80, p-trend=0.31) or fatal (HR 1.09, 95% CI 0.46–2.62, p-trend=0.97) MI. Conclusion: This study does not confirm an inverse association between menaquinones intake and coronary heart disease as shown in two Dutch cohorts. The here observed inverse association for phylloquinone intake should be interpreted with caution since it was significant only for fatal MI (and thus based on small numbers).
Acoustic and electrical effects in the atmosphere surface layer due to some ionospheric sources

Field: Physics and Astronomy (Physical Sciences)

We present experimental results of the study of acoustic gravity waves and electric field generation during auroras. Vertical component of electric field in the atmosphere surface layer and atmosphere pressure were recorded during the field study. Analysis of the obtained data shows that synchronous variations of the pressure and electric field strength appear with the development of auroras. It is seen that the amplitude of electric field perturbations is approximately proportional to the amplitude of variation in the pressure.

Results of the field studies conducted in two counties of Shaanxi Province during 1988 to 1989 revealed differences in parasitization of imported cabbage worm, Pieris rapae by different species or strains of Trichogramma. Among two species, Trichogramma evanescens and T. chilonis arid different strains of the former, three strains of T. evanescens (LG-46, DH-9, and DG-11) produced egg parasitization of over 63%, which was significantly higher than that by other strains of the species and by T. chilonis.
Low-Complexity and Low-Power MIMO Symbol Detector for Mobile Devices with Two TX/RX Antennas

Field: Computer Science (Physical Sciences)

In this paper, a low-complexity and lowpower soft output multiple input multiple output (MIMO) symbol detector is proposed for mobile devices with two transmit and two receive antennas. The proposed symbol detector can support both the spatial multiplexing mode and spatial diversity mode in single hardware and shows the optimal maximum likelihood (ML) performance. By applying a multistage pipeline structure and using a complex multiplier based on the polar-coordinate, the complexity of the proposed architecture is dramatically decreased. Also, by applying a clockgating scheme to the internal modules for MIMO modes, the power consumption is also reduced. The proposed symbol detector was designed using a hardware description language (HDL) and implemented using a 65nm CMOS standard cell library. With the proposed architecture, the proposed MIMO detector takes up an area of approximately 0.31mm2 with 183K equivalent gates and achieves a 150Mbps throughput. Also, the power estimation results show that the proposed MIMO detector can reduce the power consumption by a maximum of 85% for the various test cases.
Closed string tachyon: inflation and cosmological collapse

Field: Physics and Astronomy (Physical Sciences)

By compactifying a critical bosonic string theory on an internal non-flat\nspace with a constant volume, we study the role played by the closed string\ntachyon in the cosmology of the effective four-dimensional space-time. The\neffective tachyon potential consists on a negative constant related to the\ninternal curvature space and a polynomial with only quadratic and quartic terms\nof the tachyon field. Based on it, we present a solution for the tachyon field\nand the scale factor, which describes an accelerated universe which expands to\na maximum value before collapsing. At early times, the closed string tachyon\npotential behaves as a cosmological constant driving the Universe to an\nexpansion. The value of the cosmological constant is determined by the\ncurvature of the internal space which also fixes the value of the vacuum\nenergy. As time evolves, inflation is present in our models, and it finishes\nlong before the collapsing. At late times, we show that the collapse of the\nUniverse starts as soon as the tachyon field condensates. We also comment on\nthe consistency of our solution at early times at which quantum aspects become\nimportant under the perspective of quantum cosmology. Finally we briefly\nmention the relation among the curvature of the internal space and the value of\nthe energy vacuum in a non-constant internal volume scenario.\n
CARPAL INSTABILITY WITH SCAPHO-LUNATE DISSOCIATION: RECONSTRUCTION CORRECTION OF THE VOLAR SCAPHOTRAPEZOID LIGAMENT WITH THE PALMARIS LONGUS TENDON

Field: Medicine (Health Sciences)

Purpose: Carpal instability with scapho-lunate dissociation is still considered to result from the rupture of the so-called scapho-lunate (SL) ligament. Actually, this is not a ligament but a loose capsule allowing flexion of the scaphoid and lunate of very different magnitudes (92° versus 20°. Reconstruction of the SL “ligament” have often provided very disappointing results. Material: Sections of the SL “ligament” on cadaveric specimens never produce SL dissociation. This dissociation can only occur if the scaphoid remains well-positioned in the articular facette of the radius. Rotory subluxation is possible only if the scapho-trapezotrapezoidal is cut, which allows posterior displacement of the scaphoid. This ligament is not described in anatomy textbooks because it is hidden by the sheath of the palmaris longus. Posterior luxation of the proximal pole of the scaphoid is required for dissociation from the semi-lunate. Operative method: A reconstruction method for the volar scaphotrapezoid ligament using a band of the flexor carpi radialis tendon was developed on cadaveric specimens before application in 38 patients. The 7-cm band of the palmaris longus tendon, with an intact metatarsal attachment was passed through a tunnel drilled in the distal pole of the scaphoid. The band was then pulled dorsally (correctly positioning the scaphoid) and sutured to the dorsoulnar border of the radius. Results: Carpal height was restored as was scaphoid-lunate mobility (flexion in radial deviation, extension in cubital deviation). The reduction was maintained at mid- and long-term with prevention of carpal collapse and arthritis. Among the 38 operated patients, 35 achieved full pain relief, three complained of moderate pain under stress. All patients were satisfied. Discussion: Anatomic research and clinical results confirmed that the scaphotrapezoidal ligmament is the key element for dissociation and its repair. Conclusion: This operation is currently the only procedure capable of providing easy and definitive repair of carpal instability with scapho-lunate dissociation.
Plasma lipid fractions during long‐term monotherapy with the ISA‐ containing beta‐adrenoceptor blocker bopindolol in hypertensive patients.

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

The influence of bopindolol monotherapy on blood pressure and plasma lipid fractions was investigated in 24 hypertensive patients. Bopindolol lowered blood pressure and heart rate significantly. When compared with placebo no changes were found in the plasma concentrations of total cholesterol, LDL cholesterol and HDL cholesterol. Plasma triglycerides were significantly increased after 4 and 8 weeks but not after 12 weeks of bopindolol. It is concluded that bopindolol is an effective and well tolerated beta‐adrenoceptor blocker in hypertensive patients. The fact that it does not lower HDL cholesterol could be a potential advantage.
Secretor Status of ABO Antigens in Saliva of a Defined Group of Iranian Patients with Pemphigus Vulgaris: A Case-Control Study

Field: Medicine (Health Sciences)

Introduction . Pemphigus is a chronic inflammatory and autoimmune disease which can cause blisters and mucocutaneous erosions. ABO secretor refers to those who secrete ABO blood group antigens based on their blood type in body fluids such as saliva, sweat, tears, semen, and serum. Previous studies showed that nonsecretor people are more prone to certain autoimmune diseases. Aim . The aim of this study was to determine the ABO secretor status in the saliva of patients with pemphigus vulgaris. Materials and Methods . This case-control study was conducted on 35 patients with pemphigus vulgaris and 35 healthy controls. The two groups were matched for age and gender. Pemphigus vulgaris diagnosis was confirmed by histopathology and direct immunofluorescence microscopy. ABO blood grouping was done, and 5 ml of unstimulated saliva was collected to determine secretor status. Secretors were recognized from nonsecretors by the Wiener agglutination inhibition test. Results were extracted by using statistical chi-square and Fisher’s exact tests. Results . 16 male and 19 female patients aged 49.43 ± .12.37 years were compared with 16 male and 19 female controls aged 46.43 ± 11.88 years. The most frequent blood group among case and control groups was O (54.3% and 60%, respectively). There was no significant difference in blood groups (P=0.73). 90% of the samples were ABO secretors. The patient group included 31 (88.6%) and the control group included 32 (91.4%) ABO secretors; there was no significant difference between the two groups (P=1.000). Conclusion . In this study, we observed that the people with nonsecretor status in comparison with the people with secretor status are not more susceptible to develop pemphigus vulgaris.
Protein Arp and protein H from group A streptococci. Ig binding and dimerization are regulated by temperature

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Abstract Cell surface proteins that bind to the Fc part of Ig are expressed by many strains of group A streptococci, an important human pathogen. Two such bacterial strains, AP4 and AP1, were shown to bind IgA and IgG, respectively, in a temperature-dependent manner. The binding of radiolabeled Ig to the bacterial cells was lower at 37 degrees C than at 22 and 4 degrees C. Similarly, protein Arp, the IgA-binding protein isolated from strain AP4, and protein H, the IgG-binding protein isolated from strain AP1, displayed a strong Ig-binding at 22 degrees C and lower temperatures, and virtually no binding at all at 37 degrees C. The effect was reversible: lowering of the temperature restored the binding and vice versa. A gradual shift between binding and nonbinding took place between 27 and 37 degrees C. Gel chromatography and velocity sedimentation centrifugation showed that protein Arp and protein H appeared as noncovalently associated dimers at 10 and 22 degrees C, and as monomers at 37 degrees C. These results strongly suggest that the dimerization of protein Arp and protein H, rather than the low temperature itself, yielded the strong Ig-binding of the proteins at 10 and 22 degrees C. Indeed, after covalent cross-linking of the dimers at 10 degrees C by incubation with low concentrations of glutaraldehyde, full Ig-binding was achieved even at 37 degrees C. A carboxyl-terminal proteolytic fragment of protein Arp, which completely lacked the IgA-binding capacity at any temperature, showed the same temperature-dependent dimerization as intact protein Arp, suggesting that the Ig-binding part of the protein is not required for dimerization. The implications of these results for the function of Ig-binding group A streptococcal proteins, and their role in the host-parasite relationship are discussed.
Physiological Limits of MRI

Field: Medicine (Health Sciences)

Introduction Prior to the discovery of high field type 2 superconductivity in the mid-20th century [1] there was no practical means of generating steady magnetic fields on the order of one tesla over a volume as large as an entire human body. Consequently, there has been no opportunity for evolutionary adaptation to magnetic fields of this strength and there was little information regarding the safety of human exposure to intense magnetic fields in the early 1980s when clinical MRI was introduced on a large scale [2]. Most of the available information at that time resulted from limited, informal studies of exposure to magnets utilized in high-energy physics laboratories [3]. Nonetheless, since approximately 1982, on the order of 200,000,000 clinical MR scans have been performed and, except for issues associated with the presence of magnetic foreign bodies (put in place by trauma or by surgical intervention) or the inadvertent scanning of patients with implanted pacemakers or similar devices, there is little or no evidence for any significant pathology associated with the action of the static magnetic field [4]. The very high degree of patient safety in strong magnetic fields is attributed to the extremely low value of the magnetic susceptibility and the lack of ferromagnetic components in these tissues [5].
