Contractile properties of fibroblasts derived from primary frozen shoulder and effects of TGF beta 1 stimulation
INTRODUCTION: Primary Frozen Shoulder (PFS) is a debilitating disease of unknown aetiology. There is fibrosis and contracture of the coracohumeral ligament, tissues of the rotator interval and the glenohumeral ligaments, leading to restrictive shoulder movements requiring surgical intervention [1]. Frozen shoulder has been postulated to be dupuytrenâs disease of the shoulder with an association inferred since 1936. The purpose of the study was to test the hypothesis that cellular mechanisms of fibroblasts derived from primary frozen shoulder exhibited similar activity in terms of contraction and response to cytokine (transforming growth factor beta1) to fibroblasts derived from dupuytrenâs disease. Understanding of cellular responses is critical to developing non surgical treatment strategies
Citation Styles
 The practice of evidence based medicine and widespread clinical research have rendered literature search,a vital tool .It is practically impossible to write any article without inputs from previous literature,whether from a book,journal or a website. The backbone of any publication is the bibliography or references. This is a compilation of all the sources of data used for the research paper. A reference mentions all the details of the source,namely title,authors,journal name,year,volume and issue number and page numbers. In order to avoid plagiarism,all references should be quoted in proper context after giving due credit to the respective authors. If a manuscript needs to be revised with inclusion of additional references,the authors will have to also modify the list of references appropriately to accommodate the same.
Sub-au imaging of water vapour clouds around four Asymptotic Giant Branch stars
We present MERLIN maps of the 22-GHz H2O masers around four low-mass
late-type stars (IK Tau U Ori, RT Vir and U Her), made with an angular
resolution of ~ 15 milliarcsec and a velocity resolution of 0.1 km s-1. The H2O
masers are found in thick expanding shells with inner radii ~ 6 to 16 au and
outer radii four times larger. The expansion velocity increases radially
through the H2O maser regions, with logarithmic velocity gradients of 0.5--0.9.
IK Tau and RT Vir have well-filled H2O maser shells with a spatial offset
between the near and far sides of the shell, which suggests that the masers are
distributed in oblate spheroids inclined to the line of sight. U Ori and U Her
have elongated poorly-filled shells with indications that the masers at the
inner edge have been compressed by shocks; these stars also show OH maser
flares. MERLIN resolves individual maser clouds, which have diameters of 2 -- 4
au and filling factors of only ~ 0.01 with respect to the whole H2O maser
shells. The CSE velocity structure gives additional evidence the maser clouds
are density bounded. Masing clouds can be identified over a similar timescale
to their sound crossing time (~2 yr) but not longer. The sizes and observed
lifetimes of these clouds are an order of magnitude smaller than those around
red supergiants, similar to the ratio of low-mass:high-mass stellar masses and
sizes. This suggests that cloud size is determined by stellar properties, not
local physical phenomena in the wind.Comment: 21 pages, including 14 figures and 8 tables. Accepted for publication

âI don't think I can catch itâ: women, confidence and responsibility in football coach education
Whilst womenâs participation in sport continues to increase, their presence remains ideologically challenging given the significance of sport for the construction of gendered identities. As a hegmonically masculine institution, leadership roles across sport remain male-dominated and the entry of women into positions of authority (such as coaching) routinely contested. But in powerful male-typed sports, like football, womenâs participation remains particularly challenging. Consequently, constructions of gender inequity in coaching were explored at a regional division of the English Football Association through unstructured interviews and coaching course observation. Using critical discourse
analysis we identified the consistent re/production of women as unconfident in their own skills and abilities, and the framing of women themselves as responsible for the gendered inequities in football coaching. Women were thereby
strategically positioned as deservedly on the periphery of the football category,whilst the organization was positioned as progressive and liberal
Dual-stream spatiotemporal networks with feature sharing for monitoring animals in the home cage
This paper presents a spatiotemporal deep learning approach for mouse
behavioural classification in the home-cage. Using a series of dual-stream
architectures with assorted modifications to increase performance, we introduce
a novel feature sharing approach that jointly processes the streams at regular
intervals throughout the network. To investigate the efficacy of this approach,
models were evaluated by dissociating the streams and training/testing in the
same rigorous manner as the main classifiers. Using an annotated, publicly
available dataset of a singly-housed mice, we achieve prediction accuracy of
86.47% using an ensemble of a Inception-based network and an attention-based
network, both of which utilize this feature sharing. We also demonstrate
through ablation studies that for all models, the feature-sharing architectures
consistently perform better than conventional ones having separate streams. The
best performing models were further evaluated on other activity datasets, both
mouse and human. Future work will investigate the effectiveness of feature
sharing to behavioural classification in the unsupervised anomaly detection
domain
A Search for Propylene Oxide and Glycine in Sagittarius B2 (LMH) and Orion
We have used the Mopra Telescope to search for glycine and the simple chiral
molecule propylene oxide in the Sgr B2 (LMH) and Orion KL, in the 3-mm band. We
have not detected either species, but have been able to put sensitive upper
limits on the abundances of both molecules. The 3-sigma upper limits derived
for glycine conformer I are 3.7 x 10^{14} cm^{-2} in both Orion-KL and Sgr B2
(LMH), comparable to the reported detections of conformer I by Kuan et al.
However, as our values are 3-sigma upper limits rather than detections we
conclude that this weighs against confirming the detection of Kuan et al. We
find upper limits for the glycine II column density of 7.7 x 10^{12} cm^{-2} in
both Orion-KL and Sgr B2 (LMH), in agreement with the results of Combes et al.
The results presented here show that glycine conformer II is not present in the
extended gas at the levels detected by Kuan et al. for conformer I. Our ATCA
results (Jones et al.) have ruled out the detection of glycine (both conformers
I and II) in the compact hot core of the LMH at the levels reported, so we
conclude that it is unlikely that Kuan et al. have detected glycine in either
Sgr B2 or Orion-KL. We find upper limits for propylene oxide abundance of 3.0 x
10^{14} cm^{-2} in Orion-KL and 6.7 x 10^{14} cm^{-2} in Sgr B2 (LMH). We have
detected fourteen features in Sgr B2 and four features in Orion-KL which have
not previously been reported in the ISM, but have not be able to plausibly
assign these transitions to any carrier.Comment: 12 pages, 3 figures. Accepted by MNRAS 12th January 200
