Temperature influence on embryonic development of Anopheles albitarsis and Anopheles aquasalis

open access: yesMemorias do Instituto Oswaldo Cruz, 2002
Temperature influence on the embryonic development of Anopheles aquasalis and An. albitarsis was investigated. At 26ºC, 75% and 60% of respectively An. aquasalis and An.

Effects of Hybrid Poplar (Salicaceae) Clone and Phenology on Gypsy Moth (Lepidoptera: Lymantriidae) Performance in Wisconsin [PDF]

open access: yes, 2017
Gypsy moth (Lymantria dispar) developmental interactions with two hybrid Populus species clones were studied in laboratory trials. Significant differences in larval performance were found between clones and within the same clone at different phenological

Encapsulation and Melanization Are Not Correlated to Successful Immune Defense Against Parasitoid Wasps in Drosophila melanogaster

open access: yesCells
Parasitoid elimination in Drosophila melanogaster involves special hemocytes, called lamellocytes, which encapsulate the eggs or larvae of the parasitoid wasps. The capsules are melanized, and metabolites of the melanization reaction may play a potential

The Alzheimer’s Disease γ-Secretase Generates Higher 42:40 Ratios for β-Amyloid Than for p3 Peptides

open access: yesCell Reports, 2017
Alzheimer’s disease is characterized by intracerebral deposition of β-amyloid (Aβ). While Aβ40 is the most abundant form, neurotoxicity is mainly mediated by Aβ42.

Building a Beetle: How Larval Environment Leads to Adult Performance in a Horned Beetle. [PDF]

open access: yesPLoS ONE, 2015
The link between the expression of the signals used by male animals in contests with the traits which determine success in those contests is poorly understood.

Developmental Effects of Nicotine Exposure in Drosophila Melanogaster [PDF]

open access: yes, 2017
Approximately 12%-20% of pregnant women smoke at some point during pregnancy, and 10% of pregnant women are reported to have smoked during the last 3 months of pregnancy.

Temporal and Cell‐Specific Regulation of Synaptic Homeostasis by the Chromatin Remodeler Chd1

open access: yesAdvanced Science, EarlyView.
Chd1, the Drosophila homologue of mammalian CHD2 ‐ a gene linked to autism, epilepsy, and intellectual disability, is required for synaptic homeostatic plasticity. Chd1 in glia is necessary for the rapid induction of synaptic homeostasis, whereas Chd1 in motoneurons, muscle, and glia is critical for long‐term maintenance.

The 5' untranslated region of the I factor, a long interspersed nuclear element-like retrotransposon of Drosophila melanogaster, contains an internal promoter and sequences that regulate expression [PDF]

open access: yes, 1993
The I-R system of hybrid dysgenesis in Drosophila melanogaster is controlled by a long interspersed nuclear element-like retroposon, the I factor.

MicroRNA‐375‐3p Targets Fatty Acid Synthase and Relish to Regulate Energy Allocation During Pupal Metamorphosis and Starvation

open access: yesAdvanced Science, EarlyView.
During pupal metamorphosis and starvation, elevated 20‐hydroxyecdysone (20E) and suppressed insulin trigger Forkhead box O (FOXO) nuclear translocation, enhancing miR‐375‐3p expression. This downregulates fatty acid synthase (FASN) and Relish, promoting lipid breakdown for energy while prioritizing antioxidant responses over immune functions to support

Cloning of the Neurodegeneration Gene \u3cem\u3eDrop-Dead\u3c/em\u3e and Characterization of Additional Phenotypes of its Mutation [PDF]

open access: yes, 2008
Mutations in the Drosophila gene drop-dead (drd) result in early adult lethality and neurodegeneration, but the molecular identity of the drd gene and its mechanism of action are not known.
