Is it possible to encapsulate in a pill the benefits of an analytical treatment? Quickly suspending the symptoms? Since the nineteenth century psychiatry has offered to the so called mentally ill "medieval forms" of treatment, as is the case of institutional admissions, the straightjacket, lobotomies, shock treatments, etc. What has changed since the mid-twentieth century advent of chlorpromazine, the first psychoactive drug, and the "psychopharmacological revolution"? Today with the Psychiatric Reform mental institutions admissions are being gradually abandoned, yet we see the rise of psychoactive drugs as protagonists in mental health treatment. This theoretical essay is an extension of a master's thesis in progress on the long-term use of psychotropic drugs. It falls within the field of mental health, specifically in the debate on the medicalization of society in contemporary processes of subjectivation of the psychiatric clinics and the treatment modalities currently offered to individuals in their suffering-existence. Thus, we seek to problematize this degrading psychiatric clinics, which produces what we call the pill-subject.

Quantificação de parâmetros da dinâmica da bandeja do basquetebol por variáveis temporais do salto e antropométricas

The objective of this research study was quantify the power, force of vertical impulse, jumping height and the relation of the power output during the execution of the layup in basketball, by variables associated to anthropometric data. The study was carried with seven basketball players, university students, male, from the Universidade Estadual Paulista Julio Mesquita Filho (Unesp) basketball team, from Bauru City. The players were an age of 20,7 ± 2,4 years old, body weight of 77,1 ± 9,4 kg, body fat of 14,7 ± 3,6%, lean mass of 65,5 ± 6,2 kg and height of 180,0 ± 5,0 cm. Each player did the ability of the layup three times, with a previous time to adapt. The kinetic and kinematic values was obtained from the data of a system that consists of photocells and a contact carpet from a system called JumpSystemâ (CEFISE), using after that equations of UVRM and impulse. The photocells was dispose to capture the previous run-up, as well the speedy in the time of two steps of the layup, and it was also synchronized with the contact carpet in the last step, to preserve the exactly time of the propulsion of jump. In this way, the values and the kinetic variables found was vV (2,94 ± 0,3 m's-1), vH (11,3 ± 3,4 m's-1), vI (11,8 ± 3,2 m's-1), time of contact (0,214 ± 0,2 s), angle of jump (15,9 ± 6,26 graus) and H (44,3 ± 8,9 cm). The variables and the kinematic values found was FimpV (974,9 ± 119,03 N, PP (3112,9 ± 633,9 W) and PM (1556,4 ± 316,9 W). To better understand the ability of layup in basketball, as the kinetic variables, kinematic variables and anthropometrics that determine the performance, the study did correlations between dV (H) with vV, vH, vI, angle, FimpV, PP e PM; FimpV, PP e PM com with the kinetic variables of vV, vH, vI, angle, and anthropometric variables of PC and height, and correlations of PP e PM with %G and MM. So, significant results was found between the correlations of dV with FimpV (R2 = 0,81)...

Diurnal effects on spearmint oil yields and composition

'Native'spearmint (Mentha spicata L.) is one of the two spearmint species grown commercially in the United States and other countries for essential oil production. The two major constituents of spearmint oil are carvone and limonene. It is not known if the essential oil yield (content) and composition of spearmint oil are affected by diurnal variation, and when it would be the best time for harvesting flowering spearmints within a 24h period. Therefore, the objective of this study was to evaluate the effect of diurnal variation on yield and composition of spearmint 'Native'essential oil for the environmental conditions of Northern Wyoming, at elevation 1170 m above the sea level. The experiment was conducted on a 3-year old well established spearmint plantation. The harvest times were every 2 h within a 24-h period: 7:00 AM, 9:00 AM, 11:00AM, 1:00 PM, 3:00 PM, 5:00 PM, 7:00 PM, 9:00 PM, 11:00 PM, 1:00 AM, 3:00 AM, and 5:00 AM. Essential oil yield varied from 0.96 to 1.47 g of oil per 100 g of dry herbage; the maximum oil yield was obtained at 9:00 AM and the minimum at 7:00 PM. The concentration of carvone in the oil varied from 44.1% (at 1:00 PM) to 66.4% (at 9:00 PM) of the total oil. However, the yield of carvone (a function of oil yield and carvone concentration in the oil) was the highest at 3:00 AM and the lowest at 1:00 PM. The concentration of limonene (10.7-15.8% of the oil) was the highest at 7:00 PM and the lowest at 1:00 PM, whereas the yield of limonene was the highest at 9:00 PM. For best essential oil yields, flowering spearmint should be harvested at around 9:00 AM. However, to obtain oil with high carvone concentration, spearmint should be harvested at 9:00 PM. Harvests at 1:00 PM would result in spearmint oil with low concentrations of both carvone and limonene, and hence, should be avoided. (C) 2014 Elsevier B.V. All rights reserved.

Effects of protein supplementation frequency on physiological responses associated with reproduction in beef cows

The objective of this experiment was to determine if frequency of protein supplementation impacts physiological responses associated with reproduction in beef cows. Fourteen nonpregnant, nonlactating beef cows were ranked by age and BW and allocated to 3 groups. Groups were assigned to a 3 x 3 Latin square design, containing 3 periods of 21 d and the following treatments: 1) soybean meal supplementation daily (D), 2) soybean meal supplementation 3 times/week (3WK), and 3) soybean meal supplementation once/week (1WK). Within each period, cows were assigned to an estrus synchronization protocol: 100 mu g of GnRH + controlled internal drug release device (CIDR) containing 1.38 g of progesterone (P-4) on d 1, 25 mg of PGF(2 alpha) on d 8, and CIDR removal + 100 mu g of GnRH on d 11. Grass-seed straw was offered for ad libitum consumption. Soybean meal was individually supplemented at a daily rate of 1 kg/cow (as-fed basis). Moreover, 3WK was supplemented on d 0, 2, 4, 7, 9, 11, 14, 16, and 18 whereas 1WK was supplemented on d 4, 11, and 18. Blood samples were collected from 0 (before) to 72 h after supplementation on d 11 and 18 and analyzed for plasma urea-N (PUN). Samples collected from 0 to 12 h were also analyzed for plasma glucose, insulin, and P-4 (d 18 only). Uterine flushing fluid was collected concurrently with blood sampling at 28 h for pH evaluation. Liver biopsies were performed concurrently with blood sampling at 0, 4, and 28 h and analyzed for mRNA expression of carbamoyl phosphate synthetase I (CPS-I; h 28) and CYP2C19 and CYP3A4 (h 0 and 4 on d 18). Plasma urea-N concentrations were greater (P < 0.01) for 1WK vs. 3WK from 20 to 72 h and greater (P < 0.01) for 1WK vs. D from 16 to 48 h and at 72 h after supplementation (treatment x hour interaction, P < 0.01). Moreover, PUN concentrations peaked at 28 h after supplementation for 3WK and 1WK (P < 0.01) and were greater (P < 0.01) at this time for 1WK vs. 3WK and D and for 3WK vs. D. Expression of CPS-I was greater (P < 0.01) for 1WK vs. D and 3WK. Uterine flushing pH tended (P <= 0.10) to be greater for 1WK vs. 3WK and D. No treatment effects were detected (P >= 0.15) on expression of CYP2C19 and CYP3A4, plasma glucose, and P-4 concentrations, whereas plasma insulin concentrations were greater (P <= 0.03) in D and 3WK vs. 1WK. Hence, decreasing frequency of protein supplementation did not reduce uterine flushing pH or plasma P-4 concentrations, which are known to impact reproduction in beef cows.

Healing of implants installed in over- or under-prepared sites: an experimental study in dogs

ObjectiveTo study bone healing at implants installed with different insertion torques.Material and methodsIn six Labrador dogs, all mandibular premolars and first molars were extracted. After 4months of healing, flaps were elevated, and two implant sites were prepared at each side of the mandible. In the right side of the mandible, the distal sites were prepared conventionally, while the mesial sites were over-prepared by 0.2mm. As a consequence, a final insertion torque of similar to 30Ncm at the distal and a minimal insertion torque close to 0Ncm at the mesial sites were obtained. In the left sides of the mandible, however, the recipient sites were underprepared by 0.3mm resulting in an insertion torque of 70Ncm at both implants. Cover screws were applied, and flaps sutured to fully submerge the experimental sites. After 4months, the animals were sacrificed and ground sections obtained for histological evaluation.ResultsThe mineralized bone-to-implant contact was in the range of 55.2-62.1%, displaying the highest value at implants with similar to 30Ncm insertion torque and the lowest value at the implant sites with close to 0Ncm insertion torque. No statistically significant differences were revealed. Bone density was in the range of 43.4-54.9%, yielding the highest value at implants with 70Ncm insertion torque and the lowest at the implant sites with close to 0Ncm insertion torque. The difference between the sites of similar to 30Ncm and the corresponding 70Ncm insertion torque reached statistical significance.ConclusionsSimilar amounts of osseointegration were obtained irrespective of the insertion torque applied. Moreover, implants installed in sites with close to 0Ncm insertion torque may properly osseointegrate as well.

Crecimiento, acumulación de macronutrientes y producción de melón cantaloupo y amarillo

Fueron conducidos dos experimentos individuales en el municipio de Mossoró, Rio Grande do Norte, Brazil. Se empleó dos cultivares de melón, ‘Olimpic express’ (del tipo Cantaloupo) e ‘Iracema’ (del tipo Amarillo), para evaluar el crecimiento y la acumulación de macronutrientes, bajo el diseño de bloques al azar con siete tratamientos (épocas de muestreo) y tres repeticiones. Los muestreos de plantas fueron realizados a los 14, 21, 28, 35, 42, 49 y 56 días después del trasplante (DDT). El crecimiento fue lento hasta 28 DDT en ambos cultivares evaluados, intensificándose en el periodo siguiente, alcanzando a los 56 DDT, 246.4g planta-1 , en ‘Olimpic express’,y 266.9 g planta-1, en ‘Iracema’, siendo la materia seca (MS) de los frutos correspondientes a 60% y 64% de la MS total, respectivamente. Mayores acumulaciones de N, P y K fueron obtenidos en los frutos, mientras de Ca, Mg y S en las hojas. Al final del ciclo, en ‘Olimpic express’, cuya productividad fue de 32 t ha-1, fueron acumulados 173.4, 110.1, 101.1, 26.9, 15.6 y 13.5 kg ha-1 de K, Ca, N, Mg, S y P, respectivamente, y en ‘Iracema’, cuya productividad fue de 38 t ha-1, fueron acumulados 136.0, 93.9, 84.1, 22.6, 15.4 y 9.5 kg ha-1 de K, N, Ca, Mg, S y P, respectivamente. En relación al total acumulado, las exportaciones de N, P, K, Ca, Mg y S en los frutos fueron de 61, 73, 66, 9, 35 y 39% (‘Olimpic express’)y 58, 70, 55, 6, 33 y 41% (‘Iracema’). Con una menor producción de frutos y una mayor acumulación de nutrientes, ‘Olimpic express’ ha demostrado ser menos eficiente en el uso de nutrientes que ‘Iracema’.
