AI Article Synopsis
- Thromboelastography (TEG) provides a comprehensive evaluation of blood coagulation, measuring aspects like clot initiation, kinetics, and strength.
- A study assessed TEG's applicability in 8 healthy Hispaniolan Amazon parrots, revealing a wide range of clotting times and suggesting hypocoagulability compared to dogs and cats.
- Further research is needed on TEG's effectiveness across different avian species before it can be widely recommended in clinical settings.
Article Abstract
Thromboelastography (TEG) provides a global assessment of coagulation, including the rate of clot initiation, clot kinetics, achievement of maximum clot strength, and fibrinolysis. Thromboelastography (TEG) is used with increasing frequency in the field of veterinary medicine, although its usefulness in avian species has not been adequately explored. The purpose of this preliminary study was to assess the applicability of TEG in psittacine birds. Kaolin-activated TEG was used to analyze citrated whole blood collected routinely from 8 healthy adult Hispaniolan Amazon parrots ( Amazona ventralis ). The minimum and maximum TEG values obtained included time to clot initiation (2.6-15 minutes), clot formation time (4.3-20.8 minutes), α angle (12.7°-47.9°), maximum amplitude of clot strength (26.3-46.2 mm), and percentage of lysis 30 minutes after achievement of maximum amplitude (0%-5.3%). The TEG values demonstrated comparative hypocoagulability relative to published values in canine and feline species. Differences may be explained by either the in vitro temperature at which TEG is standardly performed or the method of activation used in this study. Although TEG may have significant advantages over traditional coagulation tests, including lack of need for species-specific reagents, further evaluation is required in a variety of avian species and while exploring various TEG methodologies before this technology can be recommended for use in clinical cases.

Legumes are an interesting matrix for food production. The aim of this study was to develop functional plant-based snacks using fermented red bean (RBB) seeds enriched with the following additives: marjoram-RBM (2%); carrot-RBC (30%); and red beetroot-RBRB (15%). In the process of constructing the snacks, the focus was on the maximum use of the raw material, including aquafaba, to improve nutritional properties, sensory acceptability, and biological activity.

Rich in bioactive compounds, carbohydrates, fibers, minerals, and trace elements, apple pomace (AP) is a significant agro-industrial by-product, which pollutes and brings high management costs. The current study investigates the possibility of using an aqueous AP extract (APE) as the main ingredient in a jelly candy recipe, replacing artificial colors and flavors and improving its nutritional value. APE and formulated jelly candies were analyzed in terms of their phytochemical profile, antioxidant capacity, and color parameters.

Semiconducting single-walled carbon nanotubes (SWCNTs) are significantly attractive for thermoelectric generators (TEGs), which convert thermal energy into electricity via the Seebeck effect. This is because the characteristics of semiconducting SWCNTs are perfectly suited for TEGs as self-contained power sources for sensors on the Internet of Things (IoT). However, the thermoelectric performances of the SWCNTs should be further improved by using the power sources.

Background: Intracranial hemorrhage (ICH) is a complication of oral anticoagulation and is associated with significant morbidity and mortality. Clinical need exists for biomarkers to measure anticoagulation in patients with factor Xa inhibitor-associated ICH to assess the hemostatic effect of reversal agents. This study explored the utility of thromboelastography (TEG) to assess anticoagulation in emergency department (ED) patients who received activated prothrombin complex concentrate (aPCC) reversal for factor Xa-inhibitor-associated ICH.

Background: Early identification of developmental delay in children can help in making early intervention for its management. Routine developmental screening is not being practised in India due to lack of trained field workers, lack of awareness among parents and lack of feasible assessment screening tool. There is lack of studies that focuses on home environment provided to the children as it is associated with developmental delay.
