Cytotoxic effects on the midgut, hypopharyngeal, glands and brain of Apis mellifera honey bee workers exposed to chronic concentrations of lambda-cyhalothrin.

Chemosphere, 2020
The honeybee, Apis mellifera is economically important for its products (honey, wax, and propolis) and for its role in pollination. This insect is threated due to high population losses in both agriculture and beekeeping.

Intestinal Malrotation With Chronic Midgut Volvulus, Chylous Ascites, and Severe Malnutrition in an Adolescent: A Case Report. [PDF]

Clin Case Rep
ABSTRACT In adolescents, chronic midgut volvulus can present insidiously over years with postprandial pain and progressive malnutrition, occasionally with chylous ascites from sustained mesenteric lymphatic obstruction. Prompt surgical correction can produce marked nutritional recovery, supporting secondary rather than primary lymphatic obstruction as ...

Structural and Functional Characterization of Hermetia illucens Larval Midgut

Frontiers in Physiology, 2019
The larvae of Hermetia illucens are among the most promising agents for the bioconversion of low-quality biomass, such as organic waste, into sustainable and nutritionally valuable proteins for the production of animal feed. Despite the great interest in

Heterogeneity of midgut cells and their differential responses to blood meal ingestion by the mosquito, Aedes aegypti

bioRxiv, 2020
Mosquitoes are the most notorious hematophagous insects and due to their blood feeding behavior and genetic compatibility, numerous mosquito species are highly efficient vectors for certain human pathogenic parasites and viruses.

The Intestinal Microbiota of Hermetia illucens Larvae Is Affected by Diet and Shows a Diverse Composition in the Different Midgut Regions

Applied and Environmental Microbiology, 2018
The demand for food of animal origin is expected to increase by 2050. Since traditional protein sources for monogastric diets are failing to meet the increasing demand for additional feed production, there is an urgent need to find alternative protein ...

Spiromesifen induces histopathological and cytotoxic changes in the midgut of the honeybee Apis mellifera (Hymenoptera: Apidae).

Chemosphere, 2020
The honeybee Apis mellifera is an important pollinator that, similarly to other bees, undergoes colony losses due to several problems, including the use of pesticides in the agriculture.
