Ista Failed To Start

[Elvisa Schimke]

Itried to update ista yesterday uninstalling ista and programming data then downloading ista then the programming data file. Now I get an error message saying ista failed to start. Any help is appreciated. Thanks

Reach out to ISTA? Do you know how that works? Several hours later they give you a useless answer then your case is resolved. You ask again, wait, wait, then after a few hours you get another useless answer and your case is resolved. I have not once out of dozens of attempts gotten an answer for anything.

It is probably on their end. I have wasted a lot of time trying to get on, wondering what is wrong. The next morning it works. You do have to start it from the browser. Sign in, at the AOL dropdown, the green button.

Meet Ista Flit. Daughter. Face-changer. Thief...

Amongst the cobbled streets and misty alleyways of Shelwich, magic rises and falls with the Tide. When the Tide is out, the magic ebbs to a low murmur. When the Tide is in, the magic is high - and Tide-blessings are at their strongest.

For most people, the Tide-blessing they are born with is nothing more than a simple party trick: eyes that change colour, or the ability to recite a poem backwards. Some, though, are blessed with more powerful gifts. Telepathy. Flight. Or, in the case of Ista Flit, being able to transform to look like someone else. Anyone else...

Ista has come to Shelwich in search of her missing father, and she'll do anything to find him - even work for Shelwich's most notorious thief. Then she meets Nat and Ruby, both struggling with their own search: Nat for his little brother, Ravi, and Ruby for her sister Saf. As more strange disappearances send shockwaves through the town, they must form a tentative friendship and draw on all the Tidemagic they can to unravel a mystery that leads to an old, abandoned theatre, and to the ancient caves beneath Shelwich. But what they find there will be far more than they have bargained for...

Mary Lennox starts her life as an unhappy victim of circumstance. After the loss of her parents, she moves to rural Yorkshire to live with a distant uncle where she resents the wildness of the countryside. At first, she struggles to find a place in this new existence. Although unsure about her surroundings and its occupants, through the gentle guidance of the maid she gradually becomes interested in the story of Mrs Craven, who apparently used to spend her time in a garden at the house, the key to which has vanished.

The kingdom of Cornucopia was once the happiest in the world. It had plenty of gold, a king with the finest moustache you could possibly imagine, and butchers, bakers, and cheesemongers whose exquisite foods made a person dance with delight when they ate them. Everything was perfect - except for the misty Marshlands to the north, which, according to legend, were home to the monstrous Ickabog. Anyone sensible knew that the Ickabog was just a myth to scare children into behaving. But the funny thing about myths is that sometimes they take on a life of their own.

Total shoulder arthroplasty (TSA) is an effective treatment to restore shoulder function and alleviate pain in the case of glenohumeral arthritis [1]. Stress shielding, which occurs when bone stress is reduced due to the replacement of bone with a stiffer metallic implant, causes bone resorption of up to 9% of the humeral cortical thickness following TSA [2]. Shorter length stems and smaller overall geometries may reduce stress shielding [3], however the effect of humeral head backside contact with the resection plane has not yet been fully investigated on bone stress. Therefore, the purpose of this study was to quantify the effect of humeral head contact conditions on bone stresses following TSA.

3D models of eight male left cadaveric humeri (686 years) were generated from CT data using MIMICS. These were then virtually prepared for reconstruction by an orthopaedic surgeon to accept a short-stem humeral implant (Exactech Equinoxe Preserve) that was optimally sized and placed centrally in the humeral canal. The humeral head was positioned in the inferior-medial position such that contact was achieved on the medial cortex, and no contact existed on the lateral cortex. Three different humeral head backside contact conditions were investigated (Figure 1); full backside contact (FULL), contact with only the inferior-medial half of the resection (INF), and contact with only the superior-lateral half of the resection (SUP). Cortical bone was assigned an elastic modulus of 20 GPa and a Poisson's ratio of 0.3. Trabecular bone was assigned varying stiffness based on CT attenuation [4]. A joint reaction force was then applied representing 45 and 75 of abduction [5]. Changes in bone stress, as well as the expected bone response based on change in strain energy density [6] was then compared between the intact and reconstructed states.

Stemless prostheses are recognized to be an effective solution for anatomic total shoulder arthroplasty (TSA) while providing bone preservation and shortest operating time. Reverse shoulder arthroplasty (RSA) with stemless has not showed the same effectiveness, as clinical and biomechanical performances strongly depend on the design. The main concern is related to stability and bone response due to the changed biomechanical conditions; few studies have analyzed these effects in anatomic designs through Finite Element Analysis (FEA), however there is currently no study analyzing the reverse configuration. Additionally, most of the studies do not consider the effect of changing the neck-shaft angle (NSA) resection of the humerus nor the proper assignment of spatial bone properties to the bone models used in the simulations. The aim of this FEA study is to analyze bone response and primary stability of the SMR Stemless prosthesis in reverse with two different NSA cuts and two different reverse angled liners, in bone models with properties assigned using a quantitative computed tomography (QCT) methodology.

Sixteen fresh-frozen cadaveric humeri were modelled using the QCT-based finite element methodology. The humeri were CT-scanned with a hydroxyapatite phantom to allow spatial bone properties assignment [Fig. 1]. Two implanted SMR stemless reverse configurations were considered for each humerus: a 150-NSA cut with a 0 liner and a 135-NSA cut with a 7 sloped liner [Fig. 2]. A 105 abduction loading condition was simulated on both the implanted reverse models and the intact (anatomic) humerus; load components were derived from previous dynamic biomechanical simulations on RSA implants for the implanted stemless models and from the OrthoLoad database for the intact humeri. The postoperative bone volume expected to resorb or remodel [Fig. 3a] in the implanted humeri were compared with their intact models in sixteen metaphyseal regions of interest (four 5-mm thick layers parallel to the resection and four anatomical quadrants) by means of a three-way repeated measures ANOVA followed by post hoc tests with Bonferroni correction. In order to evaluate primary stability, micromotions at the bone-Trabecular Titanium interface [Fig. 3b] were compared between the two configurations using a Wilcoxon matched-pairs signed-rank test. The significance level α was set to 0.05.

The increasing incidence of periprosthetic femoral fractures (PFF) after total hip arthroplasty presents growing concerns due to challenges in treatment and increased mortality. PFF are often observed when the prosthesis is implanted in varus, especially with blade-type stems. To help elucidate its impact on the PFF risk, the specific research question is: What is the effect of misalignment of a blade-type stem (resulting in down-sized prosthesis) on 1)the distribution and magnitude of cortical stresses and 2)implant-bone micromotion.

The patella experiences large forces and variable kinematic patterns throughout flexion which could influence function and patient satisfaction after a total knee arthroplasty (TKA). Therefore, the objective of this study is to analyze in vivo patellar mechanism forces and kinematics throughout flexion to determine influencing factors that may lead to patient dissatisfaction.

Fifty subjects were evaluated in this study, 40 having a Journey II bi-cruciate stabilized (BCS) TKA and 10 having normal, healthy knees. Similar demographics were controlled for each group. Each subject performed a deep knee bend. Kinematics were evaluated using a validated 3D-to-2D fluoroscopic technique while forces were determined using a validated inverse mathematical knee model. A two-tailed t-test was used to evaluate statistical significance.

An understanding of anatomic variability can help guide the surgeon on intervention strategies. Well-functioning thumb metacarpophalangeal joints (MCPJ) are essential for carrying out typical daily activities. However, current options for arthroplasty are limited. This is further hindered by the lack of a precise understanding of the geometric variation present in the population. In this paper, we offer new insight into the major modes of geometric variation in the thumb MCP using Statistical Shape Modelling.
