Infiltrating syringomatous adenoma of nipple
Infiltrating syringomatous adenoma of the nipple is a rare, benign lesion with distinct clinical and histological features. Origin from ducts of dermal sweat glands has been postulated. Important differential diagnosis include nipple adenoma, tubular carcinoma and adenosquamous carcinoma. Appropriate local management includes accurate diagnosis and complete excision to avoid local recurrences. This report describes the condition in a 39-year-old parous lady
An Efficient Eulerian Video Magnification Technique for Micro-biology Applications
The micro-biology videos often contain motions of particles which are not visible to naked eye. Therefore an efficient motion magnification technique is required to magnify these motions. A time efficient eulerian video magnification technique for micro-biological applications is proposed. The proposed technique utilizes the concept of time and spatial uniformity to reduce the computational complexity. Simulation results reveal that the proposed scheme is almost four times efficient and more accurate as compared to state of art video magnification technique
Effects of a high-dose 24-h infusion of tranexamic acid on death and thromboembolic events in patients with acute gastrointestinal bleeding (HALT-IT): an international randomised, double-blind, placebo-controlled trial
Background: Tranexamic acid reduces surgical bleeding and reduces death due to bleeding in patients with trauma.
Meta-analyses of small trials show that tranexamic acid might decrease deaths from gastrointestinal bleeding. We
aimed to assess the effects of tranexamic acid in patients with gastrointestinal bleeding.
Methods: We did an international, multicentre, randomised, placebo-controlled trial in 164 hospitals in 15 countries.
Patients were enrolled if the responsible clinician was uncertain whether to use tranexamic acid, were aged above the
minimum age considered an adult in their country (either aged 16 years and older or aged 18 years and older), and
had significant (defined as at risk of bleeding to death) upper or lower gastrointestinal bleeding. Patients were
randomly assigned by selection of a numbered treatment pack from a box containing eight packs that were identical
apart from the pack number. Patients received either a loading dose of 1 g tranexamic acid, which was added to
100 mL infusion bag of 0·9% sodium chloride and infused by slow intravenous injection over 10 min, followed by a
maintenance dose of 3 g tranexamic acid added to 1 L of any isotonic intravenous solution and infused at 125 mg/h
for 24 h, or placebo (sodium chloride 0·9%). Patients, caregivers, and those assessing outcomes were masked to
allocation. The primary outcome was death due to bleeding within 5 days of randomisation; analysis excluded patients
who received neither dose of the allocated treatment and those for whom outcome data on death were unavailable.
This trial was registered with Current Controlled Trials, ISRCTN11225767, and ClinicalTrials.gov, NCT01658124.
Findings: Between July 4, 2013, and June 21, 2019, we randomly allocated 12 009 patients to receive tranexamic acid
(5994, 49·9%) or matching placebo (6015, 50·1%), of whom 11 952 (99·5%) received the first dose of the allocated
treatment. Death due to bleeding within 5 days of randomisation occurred in 222 (4%) of 5956 patients in the
tranexamic acid group and in 226 (4%) of 5981 patients in the placebo group (risk ratio [RR] 0·99, 95% CI 0·82â1·18).
Arterial thromboembolic events (myocardial infarction or stroke) were similar in the tranexamic acid group and
placebo group (42 [0·7%] of 5952 vs 46 [0·8%] of 5977; 0·92; 0·60 to 1·39). Venous thromboembolic events (deep vein
thrombosis or pulmonary embolism) were higher in tranexamic acid group than in the placebo group (48 [0·8%] of
5952 vs 26 [0·4%] of 5977; RR 1·85; 95% CI 1·15 to 2·98).
Interpretation: We found that tranexamic acid did not reduce death from gastrointestinal bleeding. On the basis of our
results, tranexamic acid should not be used for the treatment of gastrointestinal bleeding outside the context of a
randomised trial
Effect of aluminum doping concentration on optical, magnetic and microstructural properties of MnZnO thin films
FOSS Localization: A Solution for the ICT Dilemma of Developing Countries
Information and communication technology (ICT) has tremendously expanded over the last three decades making the access to right information at the right time feasible ensuring the success of an individual, organization or culture. In order to make the most out of this exciting revolution one must be in a position to afford and completely comprehend what is offered by this technology. Unfortunately most of the software are controlled by proprietary that are economically unaffordable for developing countries and are based on language that is not comprehendible by their masses. Software localization of Free and Open Source Software (FOSS) is an effort that addresses this twofold dilemma. FOSS made software affordable while localization bridges the language barrier that helps people to fully comprehend and utilize the benefits of ICT. In this research we have explored various aspects of the software localization of free and open source operating system (FOSOS) and developed a working prototype. Paper explains concept and all the technical steps of FOSS localization of Ubuntu Linux that is a FOSOS with a foreseeable future work. 1
Characteristics of Al-doped ZnO:Ni films grown on glass by solâgel dip coating technique
Al-doped NiZnO thin films were fabricated by dip coating and annealed at various temperatures (250â550 °C) and their properties were evaluated. With increasing annealing temperature, the Al contents in the thin films were continually increased, because of the rapid increase in the incorporation efficiency of the AlâO layer with respect to the NiZnâO layer. Polycrystalline nature of the thin films was confirmed by the X-ray diffraction technique. All films have a perfect wurtzite structure without any recordable variation in the ZnO lattice produced by replacing Zn with Ni and Al. The absorption edge shifted to a higher wavelength (red shift) with the increase of annealing temperature indicating that the shrinkage of the optical band gap was induced. The optical band gaps of thin films decreased from 3.5 to 2.5 eV. All films showed ferromagnetic behavior. The annealing process provided a reduced resistivity due to the improved crystal structure of films
