Adrenoceptors in GtoPdb v.2021.3

2021

The nomenclature of the Adrenoceptors has been agreed by the NC-IUPHAR Subcommittee on Adrenoceptors [60, 186]. Adrenoceptors, α1 The three α1-adrenoceptor subtypes α1A, α1B and α1D are activated by the endogenous agonists (-)-adrenaline and (-)-noradrenaline. -(-)phenylephrine, methoxamine and cirazoline are agonists and prazosin and doxazosin antagonists considered selective for α1- relative to α2-adrenoceptors. [3H]prazosin and [125I]HEAT (BE2254) are relatively selective radioligands. S(+)-niguldipine also has high affinity for L-type Ca2+ channels. Fluorescent derivatives of prazosin (Bodipy FLprazosin- QAPB) are used to examine cellular localisation of α1-adrenoceptors. α1-Adrenocepto…

Exercise as an Adjuvant Intervention in Opiate Dependence

2013

We read with interest the article by Weinstock et al. in whichthe authors propose exercise as an adjuvant intervention inopiate agonist treatment based on current research findings(1).The use of an opiate agonist, such as buprenorphine, butmainly, methadone, for the treatment of opiate dependenceis currently an effective therapy for this type of addiction.The main benefits of this treatment occur through a relieffrom craving narcotic drugs, a temporally suppression ofwithdrawal symptoms, and by blocking the euphoric effectsof opiates (2). Unfortunately, patients needing treatment foropiatedependenceoftenfaceavarietyofco-occurringissues,suchashepatitisBandCvirusesorhumanimmunodeficiencyvirus (H…

Efficacy of epidural anesthesia for retroperitoneoscopic renal biopsy

2000

Laparoscopic procedures are performed using general anesthesia due to the perceived limitations of regional anesthesia in the upper abdomen and retroperitoneum. We present our initial experience with epidural anesthesia for retroperitoneal laparoscopic renal biopsy.

Resolving Binding Events on the Multifunctional Human Serum Albumin

2020

Abstract Physiological processes rely on initial recognition events between cellular components and other molecules or modalities. Biomolecules can have multiple sites or mode of interaction with other molecular entities, so that a resolution of the individual binding events in terms of spatial localization as well as association and dissociation kinetics is required for a meaningful description. Here we describe a trichromatic fluorescent binding‐ and displacement assay for simultaneous monitoring of three individual binding sites in the important transporter and binding protein human serum albumin. Independent investigations of binding events by X‐ray crystallography and time‐resolved dyn…

202C.S.E. analgesia in active labor: effects of the intrathecal administration of l-Bupivacaine or Ropivacaine on onset and side effects

Interpleurale Katheteranalgesie

1994

Interpleural analgesia is a method of postoperative analgesia that was developed by Kvalheim and Reiestad in 1984. The main indication is postoperative pain after unilateral thoracic and upper abdominal surgery. Many authors report good analgesic effects and better postoperative lung function following cholecystectomy. There is some controversy on the effectiveness of this method after thoracic surgery. Further indications are post-traumatic pain after multiple rib fractures and chronic pain in the upper abdomen (carcinoma of the pancreas, chronic pancreatitis). The local anaesthetic of choice is bupivacaine (in concentrations of 0.25-0.75%, injection volumes of 10-40 ml, with or without ep…

Effects of Different Glucose Concentrations on Spinal Anaesthesia with Bupivacaine and Tetracaine

1989

The effects of 5% and 8% glucose in 0.5% tetracaine or bupivacaine on the anaesthetic spread were investigated in 80 urological patients requiring spinal anaesthesia for trans-urethral resection of the prostate. The local anaesthetic solutions were randomly administered, the patients being divided into four groups of 20, and the anaesthetic profile was then evaluated in a double-blind fashion by an independent observer. Maximum cephalad spread of analgesia was significantly greater with tetracaine in 8% glucose compared to the other three groups (tetracaine/5% glucose, bupivacaine/5 or 8% glucose) (P less than 0.05). Glucose concentration significantly influenced spreading characteristics o…

ESRA19-0543 Analgesic effects of dexamethasone when given perineurally or intravenously in the upper arm bone fracture and shoulder joint surgery

2019

Background and aims Shoulder surgery is associated with severe pain. Pain delays rehabilitation and lowers quality of life. Finding adjuvants to the LA to improve analgesia and facilitate mobilization has been the focus of researchers recently. The aim of this work was to investigate which administration methods—dexamethasone perineural or intravenously—prevents pain more effectively. Methods Prospective, randomized study conducted at Hospital of Traumatology and Orthopaedics after ethics committee approval. Study involved 75 patients with upper limb fracture or shoulder joint surgery in RA and GA. Group I: Bupivacaine 0.25% 70 mg + Dexamethasone 8 mg perineurally Group II: Bupivacaine 0.25…

Dual inhibition of cyclooxygenase-1 and 5-lipoxygenase by aerial part of Bupleurum fruticescens methanol extract

2003

The effect of the methanol extract from aerial parts of Bupleurum fruticescens on the release of eicosanoids and hydrolytic enzymes was determined on in vitro cell systems. The extract had a significant effect on 5-lipoxygenase (5-LOX) activity, inhibiting both LTB4 and 5(S)-HETE production with IC50 values of 112 microg/ml and 95 microg/ml, respectively. At concentrations of 200 microg/ml, the extract also inhibited cyclooxygenase-1 (90%) and elastase activities (54%). The 12-LOX activity in intact platelets was not affected; a fact, which suggests that phospholipase A2 (PLA2) activity, is not modified by the extract.
