Pulsed Ultrasound Does Not Affect Recovery From Delayed Onset Muscle Soreness

Aim: To investigate the effects of pulsed Ultrasound (US) in recovery from Delayed Onset Muscle Soreness (DOMS). Methods: Twelve healthy male athletes (mean age 23.83±1.697 year) performed an eccentric exercise protocol of non-dominant elbow flexors to induce muscle soreness on 2 occasions separated by 3 weeks. Subjects in experimental group received pulsed US (1 MHz, intensity 0.8 W/cm2, mark space ratio 1:10), whereas control group received sham US after 24 h, 48 h and 72 h. Perception of muscle soreness, active ROM and muscle strength were the parameters measured at 0 h, 24 h, 48 h and 72 h with the help of VAS, manual goniometer and JONEX muscles master instrument respectively. Results: Post hoc t test analysis revealed significant differences (p <0.05) between 0 h and 72 h in the parameter of ROM (t = 6.18) and muscle power (t = 2.54) as well as between 24 h and 48 h in the parameter of muscle soreness (t = 3.13) in control group. Similar differences were also observed in the experimental group. No significant inter-group differences at α level of 0.05 was observed in any parameter at any level. Conclusion: The pattern of recovery from DOMS was not influenced by the application of pulsed Ultrasound at the parameters discussed here

Immunohistochemical expression of p16INK4a in premalignant lesions and malignant tumours of cervix

Background: Cervical carcinoma is the third most common cancer in women worldwide and firth most common cause of cancer related deaths. Human Papilloma virus, the most common cause of cervical cancer, causes functional inactivation of pRb, resulting in overexpression of p16INK4a. The overexpression of p16INK4a correlates well with the degree of cervical dysplasia and neoplasia. The present study is done to determine the IHC expression of p16INK4a so that it may be used as a biomarker for HPV and may play a role in the prevention, diagnosis and prognosis of cervical neoplasm. Methods: The present study was conducted on 60 formalin-fixed, paraffin-embedded specimens of cervical neoplasms, which comprised 47 cases of squamous cell carcinoma followed by 8 cases of adenocarcinoma, 3 cases of HSIL and 2 cases of LSIL. These were then subjected to IHC by p16INK4a. Cytoplasmic and nuclear positivity for p16INK4a was noted. Results: Overall 95% cases were positive for p16INK4a expression, 100% cases of adenocarcinoma, 98% cases of squamous cell carcinoma, 100% cases of HSIL and 0% cases of LSIL were positive for p16 expression. Conclusions: The present study showed statistical correlation of immunoreactivity of p16INK4a with histological type was clinically significant (p value &lt;0.0001). In our study, p16INK4a immunohistochemical expression increased with increasing degree of dysplasia and with presence of cervical carcinoma

Non-steady Force Measurement in an Orpheous Gas Turbine Engine Using Hydraulic Analogy

Determination of non-steady forces in a real turbine stage is difficult due to local flow conditions e.g. high pressure, high temperature and inaccessibility to the region etc. Experimentation in a real turbine is also prohibitive due to the costs involved. Recently, an alternative method of arriving at these non-steady forces through use of hydraulic analogy has been tried on flat plates. The paper describes the simulation of an orpheous gas turbine engine stage on the rotating water table. It discusses the modelling aspects and presents a comparison of the experimental and theoretical results obtained

Common Representation of Information Flows for Dynamic Coalitions

We propose a formal foundation for reasoning about access control policies within a Dynamic Coalition, defining an abstraction over existing access control models and providing mechanisms for translation of those models into information-flow domain. The abstracted information-flow domain model, called a Common Representation, can then be used for defining a way to control the evolution of Dynamic Coalitions with respect to information flow

Room temperature magnetic imaging of magnetic storage media and garnet epilayers in the presence of external magnetic fields using a sub-micron GaAs SHPM

Cataloged from PDF version of article.A multipurpose room temperature scanning Hall probe microscope (RT-SHPM) system incorporating an ultra-high sensitive sub-micron GaAs Hall probe (active area of similar to0.8 x 0.8 mum(2) room temperature Hall coefficient of 0.3 Ohm /G) exhibiting extremely high magnetic field sensitivity (0.04G/root Hz) was used for the direct, non-invasive and quantitative imaging of magnetic field fluctuations in very close proximity to the surfaces of thin film magnetic storage media, Bi substituted iron garnet epilayers and demagnetized Sr-ferrite permanent magnets placed in external magnetic fields. A scanning tunnelling microscope tip integrated adjacent to the Hall probe was used for precise vertical positioning of the probe. RT-SHPM images of 1.4 MB written floppy disks clearly showed well-defined magnetic transitions to coalesce into small island-like structures under external perpendicular fields greater than 1300 Oe. The RT-SHPM is demonstrated to be a versatile means of quantitatively monitoring micron-sized magnetic domain structures in the presence of external magnetic fields at: room temperature.

Room temperature scanning Hall probe microscopy of localized magnetic field fluctuations on the surfaces of magnetic recording media, permanent magnets and crystalline garnet films in external bias fields

Cataloged from PDF version of article.A sub-micron room temperature scanning Hall probe microscope (RT-SHPM) was used for real-time imaging of surface magnetic domains of floppy disks, Sr ferrite magnets and Bi-substituted iron garnets placed in large external bias fields. Domain wall nucleation was observed in the garnets where bubble lattices expanded, collapsed and transformed into stripe domains in cyclic bias fields. Evolution of RT-SHPM images was compared with conventional vibrating sample magnetometer measurements. (C) 2002 Elsevier Science B.V. All rights reserved

Characterizing Distances of Networks on the Tensor Manifold

At the core of understanding dynamical systems is the ability to maintain and control the systems behavior that includes notions of robustness, heterogeneity, or regime-shift detection. Recently, to explore such functional properties, a convenient representation has been to model such dynamical systems as a weighted graph consisting of a finite, but very large number of interacting agents. This said, there exists very limited relevant statistical theory that is able cope with real-life data, i.e., how does perform analysis and/or statistics over a family of networks as opposed to a specific network or network-to-network variation. Here, we are interested in the analysis of network families whereby each network represents a point on an underlying statistical manifold. To do so, we explore the Riemannian structure of the tensor manifold developed by Pennec previously applied to Diffusion Tensor Imaging (DTI) towards the problem of network analysis. In particular, while this note focuses on Pennec definition of geodesics amongst a family of networks, we show how it lays the foundation for future work for developing measures of network robustness for regime-shift detection. We conclude with experiments highlighting the proposed distance on synthetic networks and an application towards biological (stem-cell) systems.Comment: This paper is accepted at 8th International Conference on Complex Networks 201
