Autoantibodies against phosphatidylserine and DNA during canine Dirofilaria immitis infection.

Heartworm infection caused by Dirofilaria immitis induces a devastating disease that greatly affects the global canine population. The mechanism leading to heartworm pathology has been attributed to be mostly by mechanical damage of the worm to the dog´s vascular system and immune-mediated, but the latter processes are not completely understood. Autoantibodies targeting host molecules such as lipids and nucleic acids have been described with pathological roles during malaria and COVID-19 and mediating anemia and thrombocytopenia.

Deficit Irrigation with Silicon Application as Strategy to Increase Yield, Photosynthesis and Water Productivity in Lettuce Crops.

In regions where water is a limited resource, lettuce production can be challenging. To address this, water management strategies like deficit irrigation are used to improve water-use efficiency in agriculture. Associating this strategy with silicon (Si) application could help maintain adequate levels of agricultural production even with limited water availability.

An Inexpensive System to Investigate the Daily Rhythms of Insects.

Insects' daily rhythms occur in response to their surrounding environment. Recognizing the daily rhythms of pathogen vectors can be helpful in developing effective, safe, and sustainable management strategies to control vector insects and reduce the spread of pathogens. However, studying the daily rhythm of insects often requires costly or labor-intensive trapping, and few tools are available to quantify daily rhythms in the field.

Emerging Lagochilascaris minor infections in domestic cats from Costa Rica: A zoonotic threat for the region.

Two cases of lagochilascariasis minor in domestic cats from Costa Rica within a period of two months are recorded for the first time in Central America. Clinical findings included purulent discharge and a tumor in the left ear in one of the cats, whereas the other cat had an ulcerated cervical lesion. Both patients underwent surgical procedures during which nematode worms were collected and analyzed.

Sequential Measurements for Quantum-Enhanced Magnetometry in Spin Chain Probes.

Quantum sensors outperform their classical counterparts in their estimation precision, given the same amount of resources. So far, quantum-enhanced sensitivity has been achieved by exploiting the superposition principle. This enhancement has been obtained for particular forms of entangled states, adaptive measurement basis change, critical many-body systems, and steady state of periodically driven systems.
