Determination of mirtazapine (MRP) during psychopharmacotherapy in biological fluids is essential to achieve successful therapy, to avoid toxicity related to drug interactions, genetic variability, and poor compliance. A new, rapid, and sensitive high-performance liquid chromatography method has been developed in human plasma for the determination of MRP and N-desmethylmirtazapine (NDM) that is an active metabolite. The separation was achieved on a reverse-phase C18 250 x 4.6 mm i.d., ODS-3 column using programmed gradient elution at 40 °C. 20 mM potassium phosphate buffer (pH 3.9), acetonitrile, and triethylamine (75.024.90.1, v/v/v) were used as mobile phase A. Mobile phase B consisted of absolute acetonitrile. Clozapine was used as an internal standard. The method showed linearity with good determination coefficients (r2≥0.9981) for each analyte. Intra-day and interday assay precisions (RSD%) were found less than 3.4 and 2.9 for MRP and NDM, respectively. The intra-day and interday accuracy (RE%) of the method were calculated between (-2.8) and 5.5. A new extraction method was used in the study and an excellent recovery (average) values for MRP and NDM (94.4%, 106.6%, respectively) was obtained. The method was specific and sensitive as the limit of detection (LOD) were 0.17 for MRP and 0.15 ng/mL for NDM. This method was applied properly to plasma samples taken from patients receiving MRI (n = 62) treated with 15-30 mg / day.

The described procedure is relatively simple, precise, and applicable for routine therapeutic drug monitoring especially in psychiatry clinics and toxicology reference laboratories.Asthma is a disease characterized by spontaneous contraction of the airways in response to a wide variety of endogenous and exogenous stimuli. Many asthma models are used to mimic the human asthma model in the literature. In order to better understand the role of the cannabinoid (CB) 2 receptor in the ovalbumin (OVA)-induced asthma model, a combination of both selective CB2 agonist (AM1241) and antagonist (AM630) was used to improve inflammatory hypersensitivity and edema in rats. In the present study, it was found that OVA decreased body weight (p less then 0.05), increased lung weights (p less then 0.05), increased diastolic and systolic blood pressure (p less then 0.001), and caused irregularity in pulmonary functions (p less then 0.001). Moreover, CB2 agonist was found not to reduce body weight, cause blood pressure and respiratory irregularities (p less then 0.05). OVA led to increase in IgE, TNF-α, IL-4, MDA level (p less then 0.001), and total WBC count (p less then .05). CB2 treatment caused to reduce the number of total WBC and the level of total protein in BALF, to hinder to increase level of MDA, IgE, TNF-α, and IL-4 (p less then 0.05) in BALF or serum or lung tissue. But CB2-antagonist treatment prevented the protective effect of CB2 agonist. The aim of this study was to study the role of the CB2 receptor in the OVA induced asthma model, to improve inflammatory hypersensitivity, and edema in the rats. The results suggested that CB2 agonist administration to OVA induced asthmatic rats via anti-asthmatic potential through inhibition of parameters such as IgE, IL-4, TNF-α, microvascular escape, and oxidative stress.<br /><br /> Conditioning in the form of football small-sided games (SSG) is being increasingly utilized as a health-promoting and performance-enhancing activity.<br /><br /> The aim of this study was to quantify and compare the physiological responses and activity demands encountered during 3-a-side, 4-a-side, and 5-a-side football SSG in recreational players.<br /><br /> Heart rate, blood lactate (BLa), rating of perceived exertion (RPE) and activity demands were measured across 2×20-min football sessions played on a 40×20-m pitch in 12 recreationally active college students. Data were collected over a period of two weeks using a repeated-measures crossover design.<br /><br /> Mean heart rate was higher (moderate) during 5-a-side than 4-a-side (p=0.02) and 3-a-side SSG (p&lt;0.001). BLa tended to be higher (small) in 3-a-side compared to 4-a-side (p=0.12) and 5-a-side SSG (p=0.46). The total distance covered was lower (large) during 5-a-side than 4-a-side SSG (p=0.02), while the total number of accelerations (p=0.01) and decelerations (p=0.02) wert interceptions. Sustained activity in 4-a-side SSG might be underpinned by format-specific structures permitting optimal team work, while isolated guarding of players in 3-a-side SSG may have exacerbated BLa responses.<br /><br /> This study aimed to examine the effects of eight weeks of dry-land strength combined with swimming training on the development of upper and lower body strength, jumping ability, and swimming performance in competitive sprinter swimmers.<br /><br /> Twenty (14 men and 6 women) university swimmers of national-level (age 20.55±1.76 years, body mass 68.86±7.69kg, height 1.77±0.06m, 100m front crawl 71.08±6.71s, 50m front crawl 31.70±2.45s) were randomly divided into two groups experimental group (EG 11) and control group (CG 9). In addition to the usual in-water training (3-4 sessions per week of ∼80min), the EG performed 8 weeks (one session per week) of strength-training (ST). The ST included bench press, full squat, countermovement jumping, countermovement jumping with free-arm movement, and the medical ball throwing. Stroke length, stroke frequency, stroke index, and swimming velocity were recorded during 50 and 100m front crawl time-trials. Strength and swimming performance were evaluated before and after 8 weeks of training.<br /><br /> The results showed a significant improvement in sprint performance (50m p&lt;0.01, d=0.47; 100m p&lt;0.05, d=0.42), stroke frequency (50m p&lt;0.01, d=0.90) and stroke index (100m p&lt;0.01, d=0.29) in the EG. Despite both groups' increased strength performance, increases in bench press were higher in the EG (p&lt;0.001, d=0.75) than CG (p=0.05, d=0.34).<br /><br /> Complementing in-water training with strength training seems to be relevant to improve upper body strength and to optimize 50m and 100m swimming performance, adapting technical patterns used during all-out swimming.<br /><br />Complementing in-water training with strength training seems to be relevant to improve upper body strength and to optimize 50 m and 100 m swimming performance, adapting technical patterns used during all-out swimming.
