Baltijos jūros priekrantėje, prie Juodkrantės, atlikti lygiavertės dozės galios (LDG) matavimai prie žemės paviršiaus ir 1 m aukštyje nuo žemės paviršiaus. Matavimai atlikti 2008 m. liepos 2 ir 10 d. 63 taškuose 2,0´0,2 km teritorijoje esant šiaurės ir pietų vėjo kryptims. Vidutinių dydžių ekstremalios reikšmės buvo 51 nSv/h ir 90 nSv/h. Tai parodo, kad LDG laukų struktūra yra nehomogeninė. LDG laukų struktūrai nustatyti ir įvertinti buvo taikytas optimalios interpoliacijos metodas trims atvejams – kai tyrimų teritorijoje atlikta 63, 33 ir 18 matavimų. Gautos identiškos LDG laukų struktūros. Rasta, kad naudojant tik 18 matavimo rezultatų modelyje gaunamas patenkinamas eksperimentinių ir teorinių rezultatų sutapimas, t. y. jų skirtumas neviršija 15 % iš 80 % duomenų palyginimo.

Abstract Fall-calving Hereford-SimAngus heifers (single-sired; BW: 451 ± 28 [SD] kg; BCS: 5.4 ± 0.7) bred to a single sire were individually-fed 100% (control; CON; n = 12) or 70% (nutrient restricted; NR; n = 13) of NASEM net energy and metabolizable protein requirements for maintenance, pregnancy, and growth from d 160 of gestation to calving. Post-calving, all females were limit-fed chopped tall-fescue hay supplemented to meet lactational nutrient requirements in Calan gates to constrain calves’ diets to milk only until d 147. Four-hour milk yields were measured 5 times; calf size was determined every 21 d. Data were analyzed with treatment, calving date, and calf sex (when P < 0.25) as fixed effects; day and day x treatment were included for milk yield. From calving to d 147, CON cows had greater (P ≤ 0.003) BW, BCS, and backfat, but NR cows gained more (P ≤ 0.004) BW, BCS, and backfat. Milk weight and volume was 15% less (main effect; P < 0.04) for NR cows. Calf size did not differ at birth (P ≥ 0.27). From d 42 to 147, calves born to NR dams had lower (P ≤ 0.02) BW. Heart, abdominal, and flank girths were less (P ≤ 0.07) for NR calves through d 147. Calf ribeye area tended to be less (P ≤ 0.11) in NR calves at d 42, 84, and 126. Nutrient restricted calves had less shoulder to rump length (d 63 to 147; P ≤ 0.08), shoulder height (d 63 to 126; P ≤ 0.02), cannon length (d 42 to 105 and 147; P ≤ 0.09), and cannon circumference (d 63 and 105 to 147; P ≤ 0.06). These data indicate that even when dams are fed to meet lactational requirements, milk yield and calf growth are reduced by late gestational nutrient restriction.

A study was conducted to compare validity, clinical, content, and supplementary scale scores of Hispanic adolescents to normative data on the MMPI-A. Volunteers, 30 boys, 17 girls, were Hispanic adolescents, aged 14 to 18 years from school and after-school settings. Analysis indicated elevated T score means on F1 (66), F2 (68), F (68), L (61), Hs (61), D (63), Sc (62), A-hea (63), A-biz (63), A-lse (61), A-las (60), A-sch (61), and IMM (61) scales for boys. Scores for low aspirations, low self-esteem, immaturity, and school problems were all interrelated. For girls, scores on no scales were elevated, but on several scales mean T scores, Hs, Hy, Ma, Si, A-anx, A-obs, A-hea, A-ang, A-las, MAC-R, and ACK, were below average This suggests the MMPI-A may underpathologize for girls. Consistent with previous findings, the boys scored higher on the Immaturity Scale than the girls. It was speculated that the boys' dislike for school and low aspirations were related to the lower education and employment of their fathers compared to those for the normative sample. The A-las, A-sch, and IMM scales may prove to be useful in identifying adolescent boys “at-risk” for dropping out of school, if replication with much larger samples confirms present findings.

"There is an urgent need to support families of children with developmental disorders, especially when it is necessary for such families to help each other. However, practice and research related to support systems for families have begun only recently in Japan. Considering these issues, the authors developed a program to support mutual exchanges among parents of children with developmental disorders. This study aimed to verify the program’s effectiveness and to examine the relationship between participants’ program experience and its effectiveness. Participants included 21 male and female parents of children with developmental disorders. The parents were in their 30s to 50s (4 in their 30s, 14 in their 40s, and 3 in their 50s) (1 male, 20 females). Effectiveness indicators included the Profile of Mood States 2nd Edition-Adult Short (POMS2-A Short) (before and after implementation), Session Impact Scale (SIS), and Mutual Exchange Support Experience Rating Scale. t-tests were conducted on the pre- and post-program results of the POMS2-A short. Results showed that scores on Anger-Hostility (t=4.77, df=20, p<.01, d=1.04), Confusion-Bewilderment (t=4.31, df=20, p<.01, d=.94), Depression-Dejection (t=2.88, df=20, p<.01, d=.63), Fatigue-Inertia (t=3.63, df=20, p<.01, d=.79), and Tension-Anxiety (t=3.61, df=20, p<.01, d=.79) in the POMS2-A Short decreased significantly after the implementation of the program. These results evidence the effectiveness of the program in improving several mood states, especially anger-hostility, tension-anxiety, depression-depression, and fatigue."

Abstract Weaned pigs (n = 308; 5.7 kg BW) were used in a 42-d study evaluating the effects of increasing injectable Fe dose at processing (d 3 after farrowing) on subsequent nursery pig performance and hematological criteria. Pigs were weaned on d 21 and allotted to pens based on previous Fe treatment with BW balanced across pens within a treatment with 5 or 6 pigs/pen and 10 pens/treatment. Treatments applied at processing were a negative control receiving no Fe injection or increasing injectable Fe (Gleptoforte, Ceva Animal Health, Lenexa, KS) to provide 50, 100, 150, 200-mg, or 200-mg plus 100-mg on d 11 post-farrowing. All pigs were fed the same diets after weaning containing 110 mg/kg of Fe from FeSO4 provided from the trace mineral premix. Growth data were analyzed as a CRD with pen as the experimental unit. Hematological criteria were analyzed as a repeated measure with pig as the experimental unit. Overall, increasing injectable Fe improved (linear; P < 0.05) ADG and ADFI (Table 1). Increasing injectable Fe up to 150 mg improved (quadratic; P = 0.011) G:F with a worsening G:F thereafter. There was no evidence of difference in growth performance (P > 0.10) between the 200-mg and the 200 + 100 mg injectable Fe treatments. Significant treatment×day interactions (P < 0.001) were observed for Hgb and Hct because pigs receiving an Fe injection less than 150-mg had increasing values through nursery while all other pigs had values remaining constant until d 63 after birth with no evidence of difference (P > 0.10) amongst all treatments at d 63 after birth. These results suggest that providing a 200-mg Fe injection at processing provides the greatest growth performance in the nursery and Fe in the diet is sufficient to meet the pigs’ Fe requirement to restore blood Fe status at the end of the nursery.

Abstract Juvenile myelomonocytic leukemia (JMML) is a rare disease in childhood which can only be cured by stem cell transplantation. The major complication is relapse in up to half of the patients. The existance and efficacy of graft-versus-leukemia (GvL) in JMML is controversial and often associated with severe graft-versus-host disease (GvHD). A 1,5 year old boy developed JMML and was transplanted from a 1 antigen mismatched UD (unmanipulated bone marrow, 8.5 Mio CD34/kg) after a CR consisting of Bu 16*1.25 mg/kg), Cy (2*60 mg/kg), Mel (1*140 mg/m2) and ATG (3*20 mg/kg). GvH prophylaxis consisted of CsA and very short MTX. The situation was further complicated by the intermittent presence of CMV, HHV-6 and EBV in the peripheral blood which was treated intermittently by intravenous ganciclovir. Engraftment occurred on day + 16. GvHD III° of the skin only developed and was treated with corticosteroids, CsA and MMF. Chimerism was complete on day +28. Beginning on day +45 an increasing autologous chimerism was detected. Therefore, immunosuppression was halted. Despite discontinuation of all immunosuppressants the autologous chimerism increased to 60–80% (d +63) and the peripheral leukocytes increased to approx 30,000/μl together with eosinophilia (d +60). Clinical signs of relapse (hepatomegaly and pulmonary obstruction) were also present. Thereafter, within a week, leukopenia and thrombocytopenia developed and the autologous chimerism decreased to 1–5%. Coinciding with the apparent GvL effect severe GvHD reappeared. Skin GvHD II–III° developed, than gut GvDH III° with massive life threatening fluid and potassium loss (day +73). In an attempt to treat both JMML and GvHD the antimetabolite purinethol 50 mg/m2 daily was given orally. Since day + 98 always an complete chimerism was observed. Gut GvHD gradually improved without further immunosuppression. The boy is now at home without evidence of disease or active GvHD more than 1 year after relapse. We speculate that in this case purinethol controlled not only the severe gut GvHD after BMT but also JMML. This antimetabolite may therefore be considered as an immunosuppressant for GvHD when malignat relapse is also present or imminent.

We evaluated earthworm abundance and biomass in plantations of different poplar species and clones as well as the effect of some soil chemical and physical properties on them. Even-aged poplar species and clones, planted at Safrabasteh Poplar Research Station about 18 years ago in the north of Iran, included: Populus deltoides Bartr. cv. 69/55 (P. d. 69/55), Populus deltoides Bartr. cv. 63/51 (P. d. 63/51), Populus euramericana Guinier. cv. 45/51 (P. e. 45/51), Populus euramericana Guinier. triplo (P. e. triplo), and Populus caspica Born M. (P. caspica), as endemic and endangered poplar species, were selected in this study. Earthworm abundance and biomass, soil texture, bulk and particle density (BD, PD), pH, organic carbon (OC), total nitrogen (N), available phosphorus (P) and exchangeable potassium (K) were evaluated. The results showed that the earthworm abundance and biomass, OC, P and N in P. d. 63/51 were higher than in the other poplar species and clones. The correlation coefficients showed a positive correlation of OC, N and a negative correlation of pH, clay, BD and P with earthworm biomass. Based on the results, compared to the other species and clones P. d. 63/51 creates favourable conditions to produce more organic matter and higher abundance and biomass of earthworms, hence it could be beneficial for maintaining the soil quality status for successive plantings.

Fragestellung: Die vorliegende Studie berichtet über eine Meta-Analyse zur Wirksamkeit psychologischer und psycho-pharmakologischer Behandlungsmethoden des pathologischen Spiels. Methode: Dazu wurde eine systematische Literaturanalyse bis einschließlich Juli 2006 der Datenbanken PsycInfo, PsyndexPlus, Pascal, Biomed, Medline und Scopus durchgeführt. Von den daraus resultierenden 144 Studien erfüllten 56 mit einem N = 3.551 die Einschlusskriterien. Inkludiert wurden sowohl Studien mit einem Prä-Post-Katamnese-Design wie auch solche mit einer Vergleichs- oder Kontrollgruppe. Effektstärken wurden nach Cohen’s d berechnet. Bei Studien mit mehr als einem Outcome-Kriterium wurden diese gemittelt. Ergebnisse: Psychopharmakologische Behandlungen (d = .83; p ≤ .01; CI(95 %) = .72 – .95) erwiesen sich zum Therapieende als effektiver als psychologische (d = .63; p ≤ .01; CI(95 %) = .54 – .72). Deren Effekte waren zum Follow-up (M = 17 Monate) jedoch hoch (d = 1.26; p ≤ .01; CI(95 %) = 1.15 – 1.37): Wegen fehlender Studien konnten keine entsprechenden Effekte für pharmakologische Behandlungen berechnet werden. Im Hinblick auf die spezifischen Behandlungen erwiesen sich Psycho-Stimulantien und Stimmungsstabilisierer als am effektivsten; bei den psychologischen Methoden waren es multimodale Programme, die aus einer Kombination von Selbsthilfe, Kompetenztrainings und Familieninterventionen bestanden. Allerdings wurden diese primär über Prä-Postvergleiche evaluiert. In diesem Design erwiesen sich jedoch in einer Reanalyse verhaltenstherapeutische Interventionen den multimodalen Programmen überlegen. In den Moderatoranalysen zeigte sich das Studiendesign als einzige bedeutsame Variable. Diskussion: Die Ergebnisse müssen als vorläufig gewertet werden, denn das Feld weist noch viele Mängel auf. So fehlen vor allem kontrollierte randomisierte Studien mit langfristigen Katamnesen. Auch wurden Kombinationstherapien noch nicht untersucht.

Abstract Hi-A™ corn is a unique type of lines and hybrids that were developed by the Texas A&M AgriLife Corn Breeding Program and have high anthocyanin and antioxidants. A completely randomized design trial was used to evaluated effects of Hi-A and low-A (regular) corn cobs and bermudagrass hay (BGH) in feedlot diets fed to female Rambouillet lambs (n = 10/treatment), with initial body weight (BW) of 30.7+1.2 kg, on dry matter intake (DMI), BW, average daily gain (ADG), and growth:feed ratio (G:F). After 14 days of adaptation, lambs were individually fed a total mixed ration with 80% concentrate and 20% of one of the roughages (Hi-A, low-A, or BGH) for 63 days. Hay was chopped, while cobs were ground using a hammermill with a 9.52-mm screen. Data were analyzed using repeated-measures ANOVA. The BW was not affected by the diet but increased (P &lt; 0.001) during the trial. Diet did not influence the ADG. However, the ADG was lower (P &lt; 0.001) in the d-42 (0.12 kg/d) than the rest of the trial (0.22 kg/d), after a period of constant high temperatures. The interaction diet vs. day affected (P &lt; 0.05) DMI. In general, lambs increased (P &lt; 0.05) DMI (g/d) and decreased (P &lt; 0.05) relative DMI (%BW) in the final part of the trial, when the animals were getting closer to the harvesting date. Lambs had lower (P &lt; 0.05) DMI of BGH diets than Hi-A diets from d-42 to d-63 and Low-A diets from d-49 to d-56. The G:F ratio was not affected by the diet but decreased (P &lt; 0.05) from the middle to the end of the trial. Corn cobs are valuable as alternative roughage for feedlot lambs, with intake and growth performance comparable to BGH.

AbstractAn understanding of healthcare super-utilizers’ online behaviors could better identify experiences to inform interventions. In this retrospective case-control study, we analyzed patients’ social media posts to better understand their day-to-day behaviors and emotions expressed online. Patients included those receiving care in an urban academic emergency department who consented to share access to their historical Facebook posts and electronic health records. Super-utilizers were defined as patients with more than six visits to the Emergency Department (ED) in a year. We compared posts by super-utilizers with a matched group using propensity scoring based on age, gender and Charlson comorbidity index. Super-utilizers were more likely to post about confusion and negativity (D = .65, 95% CI-[.38, .95]), self-reflection (D = .63 [.35, .91]), avoidance (D = .62 [.34, .90]), swearing (D = .52 [.24, .79]), sleep (D = .60 [.32, .88]), seeking help and attention (D = .61 [.33, .89]), psychosomatic symptoms, (D = .49 [.22, .77]), self-agency (D = .56 [.29, .85]), anger (D = .51, [.24, .79]), stress (D = .46, [.19, .73]), and lonely expressions (D = .44, [.17, .71]). Insights from this study can potentially supplement offline community care services with online social support interventions considering the high engagement of super-utilizers on social media.

Objetivo: Estudiar las diferencias en características antropométricas y de rendimiento físico en jugadores de diferente nivel competitivo. Métodos: 86 jugadores de fútbol sub-11 de diferente nivel competitivo fueron sometidos a pruebas de velocidad (15 y 30 metros), salto con contramovimiento (CMJ), estimación del volumen de oxígeno máximo (VO2máx), velocidad máxima de golpeo, índice de fatiga en test de saltos continuos y medidas antropométricas de peso, altura e índice de masa corporal (IMC). Resultados: Los jugadores de un mayor nivel competitivo obtuvieron mejores resultados en velocidad en 15 (p = .000; d = 1.06) y 30 metros (p = .000; d = 1.12), salto CMJ (p = .017; d = .52), VO2máx (p = .004; d = .63) y velocidad de golpeo de balón (p = .041; d = .44), pero no en el índice de fatiga del test de saltos continuos (p = .663; d = .08). A su vez, tampoco se encontraron diferencias significativas en el peso (p = .938; d = .01), la altura (p = .115; d = .34) y el índice de masa corporal (p = .471; d = .28). Conclusiones: Este estudio muestra las diferencias de rendimiento físico y en medidas antropométricas analizadas en jugadores de fútbol sub-11 de diferente nivel competitivo, las cuales no han sido previamente estudiadas dentro de la literatura científica en este grupo de edad. Los jugadores de mayor nivel competitivo obtienen mejores resultados en los tests de rendimiento físico, excepto en el índice de fatiga de altura de salto. Sin embargo, las características antropométricas no permiten discernir entre ambos grupos.Abstract. Purpose: To study the differences in anthropometric and fitness performance characteristics in football players of different competitive levels. Methods: 86 under-11 football players of different competitive levels were subjected to sprint test (15 and 30 meters), countermovement Jump (CMJ), estimation of maximal oxygen intake (VO2máx), maximal kicking velocity, fatigue index in continuous jump test and anthropometrical measures of body mass, height and body mass index (BMI). Results: Players of a higher competitive level obtained better results in 15 (p = .000; d = 1.06) and 30 meters (p = .000; d = 1.12), CMJ (p = .017; d = .52), VO2max (p = .004; d = .63) and maximal kicking velocity (p = .041; d = .44), but not in fatigue index in continuous jump test (p = .663; d = .08). Likewise, no significant differences were found in body mass (p = .938; d = .01), height (p = .115; d = .34) and body mass index (p = .471; d = .28). Conclusions: This study shows the differences in fitness performance and anthropometric measures in under-11 football players of different competitive levels, which have not been previously reported in this age group. Players of higher competitive level obtained better results in fitness performance test, except in the fatigue index of jump height. However, anthropometric characteristics do not allow to distinguish between both groups.
