The soybean cyst nematode (SCN), Heterodera glycines, is the most damaging pathogen of soybeans in the United States. To assess the severity of nematode infestations in the field, SCN egg population densities are determined. Cysts (dead females) of the nematode must be extracted from soil samples and then ground to extract the eggs within. Sucrose centrifugation commonly is used to separate debris from suspensions of extracted nematode eggs. We present a method using OptiPrep as a density gradie...

Precision swine production can benefit from autonomous, noninvasive, and affordable devices that conduct frequent checks on the well-being status of pigs. Here, we present a remote monitoring tool for the objective measurement of some behavioral indicators that may help in assessing the health and welfare status—namely, posture, gait, vocalization, and external temperature. The multiparameter electronic sensor board is characterized by laboratory measurements and by animal tests. Relevant behavi...

The animal model response against genetically modifed product may provide food safety information. This study was performed to observe behavior, histopathology and physiological responses of Wistar rat fed on the diet containing growth hormone (GH) transgenic common carp (Cyprinus carpio) meal (Ccm). Thirty rats of three-month-old (BW: 115.67–139.50g) were divided into fve treatments (six rats per treatment). The treatments were rats fed on the commercial diet without Ccm (control), a re-pellete...

Given a large number of birds in the flock, we mathematically investigate the mechanism the birds move in a collective behavior. We assume that each bird is able to know its position and velocity of other birds within a radius of communication. Thus, to be able to fly in the flock, a bird has to adjust its position and velocity according to his neighbors. For this purpose, first of all, we analyze how the connectedness of the bird interaction network affects the cohesion of the stable bird flock...

Worker bees actively forage to supply colony necessity i.e., pollens, nectar, and resin. Flight activities of the worker bees are influenced by food availability and environmental conditions. This study aimed to measure flight activities of Lepidotrigona terminata in terms of leaving and returning to the nest (including carrying of pollen and pollen type) and their relation to environmental conditions. The observation of flight activities of L. terminata were conducted from August to December 20...

Volatile metabolites are produced by plants for self-defense and as communication mediators with the environment. Terpenes are volatiles emitted as odorant cues for herbivores and microorganisms. This study was aimed to investigate volatile metabolites produced by banana flowers that attract insect vectors of BBD. The volatile metabolites from banana flowers were extracted by headspace-solid phase microextraction (HS-SPME) and identified by gas chromatography–mass spectrometry (GC-MS). It was ap...

The methonolic extract of the leaves of Pisonia alba (PA) were subjected to phytochemical analysis by standard qualitative analysis and the invitro antioxidant activity was evaluated by determination of total antioxidant capacity, 1.1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity, Antioxidant activity, Nitric oxide potential. The analyses revealed that the methanol extract of Co was able to efficiently scavenge the free radicals in a dose dependant manner. The results were compare...

The aim of this study was to characterize chemically a sample of brown propolis and determine the time of action needed for eliminating microorganisms causing bovine mastitis. It was prepared hydroalcoholic extract of brown propolis (25 mg/mL) and this was evaluated for content of total phenolic compounds, total flavonoids, qualitative and quantitative analysis of phenolic compounds by liquid chromatography coupled to mass spectrometry and antibacterial activity against Escherichia coli, Staphyl...

Neuroinflammation is known as a key player in a variety of neurodegenerative and/or neurological diseases. Brain Toll-like receptors (TLRs) are leading elements in the initiation and progression of neuroinflammation and the development of different neuronal diseases. Furthermore, TLR activation is one of the most important elements in the induction of insulin resistance in different organs such as the central nervous system. Involvement of insulin signaling dysregulation and insulin resistance a...

Eighteen lesser mouse-eared bats, Myotis blythii (Tomes 1857) (Vespertilionidae) from Zanjan Province, Iran, were examined for parasites and found to harbor one species of Cestoda, Hymenolepis rhinopomae; one species of Nematoda, Molinostrongylus alatus; one species of Diptera, Penicillidia dufourdi; and one species of mite, Spinturnix andegavinus. Myotis blythii represents a new host record for Hymenolepis rhinopomae, and Iran is a new locality record for Molinostrongylus alatus.
