A method of analysis of basic narcotic drugs in urine is described. It consists in isolation by solid phase extraction, derivation and identification by gas chromatography with mass-selective detector. The approaches applied in the above method can be used for analysis of narcotic drugs undetectable by preliminary investigations as well as for urine examination for pharmacological or other biologically active substances.

Guillain-Barré Syndrome (GBS) is an acute inflammatory polyradiculoneuropathy that affects the peripheral nervous system, predominantly impairing motor function. Pain, both somatic and neuropathic, is reported in 89% of cases and is refractory to first-line analgesics in most of these. We present the case of a 75-year-old woman with an acute presentation of areflexic flaccid tetraparesis compatible with GBS.

Involvement in minor drug offences at an early age can be a signal of the onset of a potential drug issue. This is why Sweden has considered the criminalization of personal use as a strategy to deter the progression of drug use. This study investigated how the judiciary and social services succeed in identifying and providing support to adolescents convicted of drug offences.

Children are highly sensitive to toxins which can damage their organs and lead to death. Investigating the main causes of intoxication could reduce mortality and morbidity in children. In this cross-sectional study, the documents of all poisoned patients (214 cases) admitted to the emergency department of Taleghani children`s Hospital between April 2020 and 2023 were investigated.

Introduction: The paraventricular thalamic nucleus (PVT) is recognized for its critical role in pain regulation, yet the precise molecular mechanisms involved remain poorly understood. Here, we demonstrated an essential role of the microglial adenosine A receptor (AR) in the PVT in regulating pain sensation and non-opioid analgesia.

Method And Results: Specifically, AR was predominantly expressed in ionized calcium binding adapter molecule 1 (Iba1)-positive microglia cells within the PVT, with expression levels remaining unchanged in mice experiencing persistent inflammatory pain induced by complete Freund's adjuvant (CFA).

Norepinephrine (NE) released from locus coeruleus (LC) noradrenergic (NAergic) neurons plays a pivotal role in the regulation of olfactory behaviors. However, the precise circuits and receptor mechanisms underlying this function are not well understood. Here, in DBH-Cre mice model, we show that LC NAergic neurons project directly to both anterior piriform cortex (aPC) and the olfactory bulb (OB).
