Introduction: Formalin injection induces nociceptive bahaviour in phase I and II, with a quiescent phase between them. While active inhibitory mechanisms are proposed to be responsible for initiation of interphase, the exact mechanisms which lead to termination of nociceptive response in phase II are not clear yet. Phase II is a consequence of peripheral and central sensitization processes, whi...

BACKGROUND Nitric oxide (NO) involves in polycystic ovary syndrome (PCOS), a cause of infertility in women during the reproductive age. The PCOS is now categorized as an inflammatory phenomenon. The aim of this study was to evaluate the role of NO, a proinflammatory agent, in this syndrome at histological and biochemical levels. MATERIALS AND METHODS In this experimental study, animals were f...

Effective resuscitation of the newborn requires knowledge of the cause of depression. Four major causes are trauma, asphyxia, medication, and malformation. More than one of these may contribute to depression in a single infant. The first principles of resuscitation are to avoid cooling the infant and to establish an airway. Infants with an Apgar score of 3 to 4 at one minute usually need bag-an...

Changes of the stinging response threshold of Apis mellifera scutellata were measured on foragers fixed on a holder and stimulated with an electric shock as a noxious stimulus. The threshold of responsiveness to the noxious stimulus increased when bees were previously stimulated with isopentyl acetate, which is a main component of the alarm pheromone of the sting chamber. This effect is antagon...


 Canada continues to experience an opioid crisis that has had a devastating impact on public health, highlighting the importance of management strategies for use disorder (OUD). Several agonist therapies (OATs) OUD are available in Canada, including recent approvals new brand name drugs and generic versions widely used OATs.
 Coverage criteria OATs comparable across drug plans Canada...

The Drug Addiction Treatment Act of 2000 (DATA 2000) was established to create a new paradigm for medication-assisted treatment of opiate addiction in the United States. Before enactment of DATA 2000, the use of opioid medications to treat opioid addiction was permissible only in federally approved treatment programs, ie, methadone clinics. The only medications permitted were Schedule II drugs ...

Buprenorphine/naloxone (Suboxone) comprises the partial mu-opioid receptor agonist buprenorphine in combination with the opioid antagonist naloxone in a 4 : 1 ratio. When buprenorphine/naloxone is taken sublingually as prescribed, the naloxone exerts no clinically significant effect, leaving the opioid agonist effects of buprenorphine to predominate. However, when buprenorphine/naloxone is pare...

BACKGROUND AND OBJECTIVES The United States is experiencing an epidemic of opioid-related deaths. Naloxone, the drug of choice for reversing acute opioid overdose, is not routinely prescribed for outpatient use. The aims of this project were to improve naloxone awareness, increase naloxone prescribing, and prevent opioid overdoses. METHODS A naloxone counseling intervention was implemented in...

Abstract Introduction Naloxone use has increased in recent years response to the nation’s opioid crisis. Once only available health care professionals, it is now obtainable by prescription for persons at risk substance overdose and their families. Increasing its availability seen some as an “over-the-counter solution” problem. However, while naloxone been viewed relatively safe, with a low side...

a rapid, specific and accurate proton quantitative nuclear magnetic resonance spectroscopic (1h qnmr) and also a reversed phase derivatization hplc method have been developed to quantify a toxic, uv-visible inactive and non-volatile impurity n,n-dimethylamine hydrochloride (dma∙hcl) in metformin hydrochloride (mf∙hcl), an active pharmaceutical ingradient. the method is based on proton quantitat...
