Non-proteinogenic amino acids mitigate oxidative stress and enhance the resistance of common bean plants against .

White mold, caused by the necrotrophic fungus , is a challenging disease to common bean cultivation worldwide. In the current study, two non-proteinogenic amino acids (NPAAs), -aminobutyric acid (GABA) and -alanine, were suggested as innovative environmentally acceptable alternatives for more sustainable management of white mold disease. , GABA and -alanine individually demonstrated potent dose-dependent fungistatic activity and effectively impeded the radial growth and development of mycelium.

Benzimidazole Derivatives Suppress Fusarium Wilt Disease via Interaction with of and Activation of the Antioxidant Defense System of Pepper Plants.

Sweet pepper ( L.), also known as bell pepper, is one of the most widely grown vegetable crops worldwide. It is attacked by numerous phytopathogenic fungi, such as , the causal agent of Fusarium wilt disease.

Phytohormone profiling of the sweet orange (Citrus sinensis (L.) Osbeck) leaves and roots using GC-MS-based method.

Phytohormones mainly affect plant development and trigger varied responses to biotic and abiotic stresses. The sensitivity of methods used to profile phytohormones is a vital factor that affects the results. We used an improved GC-MS-based method in the selective ion-monitoring (SIM) mode to study the phytohormone profiling in citrus tissues.

Synthesis of novel 1-pyrazolylpyridin-2-ones as potential anti-inflammatory and analgesic agents.

A new series of 4-alkyl/aryl-2-oxo-1-pyrazolyl-1,2-dihydropyridine-3-carbonitriles, pyrazolo[3,4-b]pyridine-5-carbonitriles and pyrido[2,3-d]pyrimidine-6-carbonitriles have been synthesized and tested for their anti-inflammatory and analgesic activities. Among the tested compounds, 3e and 8b exhibited comparable anti-inflammatory activity to the standard (indomethacin). Compounds 5, 7a, and 8b displayed potent analgesic activity.

Synthesis and pharmacological evaluation of novel quinoxalines as potential nonulcerogenic anti-inflammatory and analgesic agents.

Some new substituted quinoxaline and furo[2,3-b]quinoxaline derivatives have been synthesized and tested for their anti-inflammatory and analgesic activities and for their ulcerogenic potential. The pharmacological evaluation of selected synthesized compounds revealed that 5a was equipotent and compounds 3, 4b, 4e and 5b possessed strong anti-inflammatory activity in chronic inflammatory models compared with indometacin (CAS 53-86-1) as reference drug. In addition, compound 4a was the safest one and the others showed little ulcerogenic activity.

Classical conditioning during nitrous oxide treatment: influence of varying the interstimulus interval.

Classical conditioning of the rabbit nictitating membrane response (NMR) was accomplished by presenting a 75-ms tone conditioned stimulus (CS) at intervals of 0, 100, 200, 400, and 800 ms before the presentation of a 100-ms shock unconditioned stimulus. Following every four paired trials (tone followed by shock), the occurrence of conditioned responses (CRs) was tested on every fifth trial in which only tone was presented (test trials). Three doses of nitrous oxide in oxygen (0, 33, and 67%) were used during conditioning.

The interaction between nitrous oxide and isoflurane on suppression of learning: a study using classical conditioning in rabbits.

Background: Nitrous oxide (N2O) is commonly combined with a volatile agent for administration of general anesthesia. We studied the effects of N2O and isoflurane on learning of the rabbit nictitating membrane responses (NMRs).

Methods: Classical conditioning of the NMR was accomplished by presenting a 400 ms tone conditioned stimulus before the presentation of a 100 ms shock unconditioned stimulus over 6 daily training sessions.

Ketamine: acquisition and retention of classically conditioned responses during treatment with large doses.

Two experiments were conducted in rabbits to examine the effects of ketamine (0, 100, and 200 mg/kg) on the acquisition and retention of the classically conditioned nictitating membrane response (NMR). Classical conditioning of the NMR was accomplished by pairing tone and light conditioned stimuli (CS) with paraorbital shock as the unconditioned stimulus (UCS). Experiment 1 assessed the effects of the drug on acquisition and retention of conditioned responses (CR) and determined the role of previous exposure to the experimental environment.

Effects of subanesthetic concentrations of isoflurane and their interactions with epinephrine on acquisition and retention of the rabbit nictitating membrane response.

Background: Evidence concerning the concentrations of volatile anesthetics that prevent learning and recall is limited. Epinephrine is believed to enable learning during anesthesia. We investigated the effects of isoflurane and its interaction with epinephrine on learning and subsequent retention of the rabbit's classically conditioned nictitating membrane response.

The interactions of midazolam and flumazenil on human memory and cognition.

Background: Previous research has been unable to show unequivocally whether flumazenil can reverse completely, partially, or not at all the memory effects of benzodiazepines. The effects of midazolam on implicit memory are also unknown. The behavioral effects of flumazenil by itself, and the acute reversal of benzodiazepine effects, are also controversial.
