Purpose. The objective was to compare the salivary protein profiles of saliva specimens from individuals diagnosed with invasive ductal carcinoma of the breast (IDC) with and without lymph node involvement. Methods. Three pooled saliva specimens from women were analyzed. One pooled specimen was from healthy women; another was from women diagnosed with Stage IIa IDC and a specimen from women dia...

The Aedes aegypti mosquito is the principal vector of arboviruses such as dengue, chikungunya, yellow fever, and Zika virus. These arboviruses are transmitted during adult female mosquito bloodfeeding. While these viruses must transverse the midgut to replicate, the blood meal must also reach the midgut to be digested, absorbed, or excreted, as aggregation of blood meal metabolites can be toxic...

The ability to feed on vertebrate blood has evolved many times in various arthropod clades. Each time this trait evolves, novel solutions to the problem posed by vertebrate hemostasis are generated. Consequently, saliva of blood-feeding arthropods has proven to be a rich source of antihemostatic molecules. Vasodilators include nitrophorins (nitric oxide storage and transport heme proteins), a v...

background: antimicrobial peptides play a role as effectors substances in the immunity of vertebrate and inverte­brate hosts. in the current study, antimicrobial peptide was isolated from the haemolymph of the american cock­roach, periplaneta americana . methods: micrococcus luteus as gram-positive bacteria and escherichia coli as gram-negative bacteria were candi­date for injection. induction ...

Saliva of hematophagous leeches (Hirudo sp.) contains bioactive proteins which allow the leech proper feeding and storage of ingested blood, but may also exert effects in the host. Leech therapy is used to treat many different ailments in humans, although only a small fraction of salivary proteins are characterized yet. Moreover, we do not know whether complete transfer of salivary proteins sto...

Salivary gland proteins of Anopheles mosquitoes offer attractive targets to understand interactions with sporozoites, blood feeding behavior, homeostasis, and immunological evaluation of malaria vectors and parasite interactions. To date limited studies have been carried out to elucidate salivary proteins of An. stephensi salivary glands. The aim of the present study was to provide detailed ana...

Salivary biomarkers have been increasingly popular in stress research as saliva is easily produced and collection is non-invasive and not limited by geographical distance or lack of infrastructure. Several salivary biomarkers have been utilized in stress research, for instance, salivary cortisol, salivary amylase and salivary immunoglobulin A. Despite being sensitive to changes in fatigue, they...

Proteins and peptides of housefly larvae (HFL) have potential applications in food therapy. The fate HFL proteins following human gastrointestinal (GI) digestion is unknown. This study adopted a computational approach to discover released from upon GI digestion. In silico eight major 783 peptides. comprised 243 exhibiting 13 types bioactivities. Ninety-two single-function anti-dipeptidyl peptid...
