To explore the use of Caenorhabditis elegans and related nematodes for studying behavioral evolution, we conducted a comparative study of pharyngeal behaviors and neuronal regulation in free-living soil nematodes. The pharynx is divided into three parts: corpus, isthmus and terminal bulb, and pharyngeal behaviors consist of stereotyped patterns of two motions: pumping and peristalsis. Based on ...

abstract nitrogen is a key nutrient in plant growth and it is necessary for amino acid synthesis. sulfur has very important role in the biosynthesis of the alliums flavor and pungency precursors and potassium improve crop yield and quality. in order to study the effect of ammonium nitrate and potassium sulfate on concentration some of the mineral elements in onion (allium cepa l. azar shahr cv....

Lateral inhibition in the olfactory bulb is mediated by circuits that involve reciprocal dendrodendritic connections between mitral and granule cells. Because of the properties of these connections and also because odor stimuli are not represented in an obviously topographic fashion, questions have been raised about whether the function of local inhibition in the olfactory bulb can be compared ...

Over the period 1980-2009, there were 58 documented hyperthermia deaths of American-style football players in the United States. This study examines the geography, timing, and meteorological conditions present during the onset of hyperthermia, using the most complete dataset available. Deaths are concentrated in the eastern quadrant of the United States and are most common during August. Over h...

BACKGROUND Adults with obesity or type 2 diabetes mellitus (T2DM) are at higher risk for stroke and myocardial infarction. Increased carotid intima-media thickness (cIMT) and stiffness are associated with these adverse outcomes. We compared carotid arteries in youth who were lean, were obese, or had T2DM. METHODS AND RESULTS Carotid ultrasound for cIMT measurement was performed, the Young ela...

in this case report, a 36 year old female at 40 weeks' gestation is presented in whom large bilateral vestibular bulb masses were found on pelvic examination. the size of the masses was such as to cause concern that they may pose an impediment to normal parturition. our pathological findings, management and results are presented.

Intrahepatic cholangiocarcinoma (ICC) is one of the most aggressive types human cancers. Although paclitaxel (PTX) was proven to exert potent anti-tumor effects against ICC, delivery PTX still challenging due its hydrophobic property. Nanoparticle (NP)-based carriers have been be effective drug vehicles. Among their physicochemical properties, shape NPs plays a crucial role in performance cellu...
