In this study, the effect of reversible inactivation of locus ceruleus (LC) on naloxone- induced withdrawal syndrome in paragigantocellular (PGi) neurons in morphine- dependent rats was investigated. For inactivation of LC, 1 µl of lidocaine (2%) was used and for induction of withdrawal syndrome, naloxone hydrochloride (2 mg/kg) was injected systemically. The results showed that in dependent gr...

introduction: pain as a complex process in the cns has been extensively studied by many researchers. it has been found that pain is controlled by certain pathways in the cns, one of most important of which is the descending noradrenergic system. the pathway begins with locus coeruleus (lc) nucleus and ends in the spinal cord. in this study, formalin test was used as a chemical and tonic pain te...

background: bifenthrin and acorus calamus linn extract were evaluated against dengue vectors in the laboratory. methods: both bifenthrin and acorus calamus linn crude hexane extract were bioassayed against the adults and larval stages of dengue vectors aedes aegypti l. and aedes albopictus(skuse) in the laboratory. results: the a. calamus crude hexane extract exhibited a larvicidal activity aga...

An overview is provided of recent developments in the use of latent class (LC) and other types of %nite mixture models for classi%cation purposes. Several extensions of existing models are presented. Two basic types of LC models for classi%cation are de%ned: supervised and unsupervised structures. Their most important special cases are presented and illustrated with an empirical example. c © 20...

Along with the creation of new maps, current efforts for improving global land cover (GLC) maps focus on integrating maps by accounting for their relative merits, e.g., agreement amongst maps or map accuracy. Such integration efforts may benefit from the use of multiple GLC reference datasets. Using available reference datasets, this study assesses spatial accuracy of recent GLC maps and compar...

In this month’s “Column Watch,” Ron Majors discusses advances in multidimensional chromatography and comprehensive multidimensional chromatography. These techniques are well suited for the separation of complex samples. Although GC GC is fairly well developed, LC LC is in its infancy. But with fast LC columns, based on monoliths, superficially porous particles, and short sub-2m particle columns...

abstract background: “polycystic ovary syndrome (pcos) is a complex endocrine and metabolic disorder associated with ovulatory dysfunction”. “autonomic and central nervous systems play important roles in the regulation of ovarian physiology”. the noradrenergic nucleus locus coeruleus (lc) plays a central role in the regulation of the sympathetic nervous system and synaptically connected to the ...

Pancreatic Cancer (PC) is the seventh leading cause of cancer-related death worldwide and one deadliest malignant neoplasms. It difficult to diagnose at an early stage. Lung (LC) second most common cancer a tumor which spreads into nearby tissues through metastasis. One major risk factors between PC LC smoking. Since both are they may be associated with another. The main purpose this research w...
