<p>El objetivo de este trabajo fue estimar el incremento en la producción en un cultivo comercial de fresa (<em>Fragaria chiloensis</em>); a tal fin se evaluó: la producción antes y después de la introducción de abejas, clasificación del fruto, producción total y por planta, y relación costo/beneficio. Se trabajó con 360 plantas divididas en tres tratamientos: (T0) o grupo testigo (libre entrada de insectos), (T1) o grupo de exclusión parcial (insectos con acceso limitado) y (T2) o grupo de exclusión total (sin visita de insectos) cada uno con 120 plantas. Se utilizaron cuatro colmenas de <em>Apis mellifera </em>ubicadas a una distancia de 10 m del cultivo; se usó alimentación complementaria a fin de promover la predilección de las abejas hacia las flores de fresa. La polinización dirigida con abejas <em>Apis mellifera </em>produjo incrementos en la producción que pasaron de 74,5 ± 20,2 kg durante el período sin abejas a 151,3 ± 25,5 kg una vez adaptadas las colonias; ello se origina en el aumento del número de frutas por planta (61,1%) que representa además un incremento económico. La curva de producción del cultivo mejoró su comportamiento pasadas tres semanas luego de la introducción de las colmenas, lo cual se reflejó en aumento de la producción, la calidad y el tamaño de los frutos (frutos clase extra y aumento de la producción de fresas de primera).</p><p> </p><p><strong>A commercial strawberry crop (Fragaria chiloensis) being directly pollinated by bees (Apis mellifera)</strong></p><p>This work was aimed at estimating increased in production in a commercial strawberry crop, Fragaria chiloensis, production before and after introducing bees, classifying fruit, total and per plant production and cost/benefit ratio were evaluated. The research was carried out with 360 plants divided in three treatments: (T0) control group (free insect entry), (T1) partial exclusion group (limited access for insects) and (T2) total exclusion group (no visits by insects), each consisting of 120 plants. Four hives containing Apis mellifera were used, located 10 m from the crop. Complementary feeding was employed to promote predilection of bees for strawberry flowers. Directed pollination with Apis mellifera led to increased production, rising from 74.5 ± 20.2 kg during the period with no bees to 151.3 ± 25.5 kg once the colonies had adapted themselves to the crop. This, in turn, led to an increase in the number of fruit per plant (61.1%) which also represented increased economic benefit. The production curve improved three weeks after introducing the hives, this being reflected in increased production, quality and fruit size (fruit classed as extra and increased production of first class strawberries).</p>

Abstract The efficacy of five insecticides containing a.i. bifenthrin, dimethoate, spinosad, spinetoram and chlorfenapyr was evaluated following RCBD against Thrips tabaci in farmer’s field for two consecutive years. The data were recorded before and after 24 h, 48 h, 72 h and 7 days of spraying. The results showed that all the insecticides reduced thrips populations compared to controls. However, the maximum reduction in thrips population and highest onion bulb yield (34.07 t/ha) was obtained with dimethoate 40EC followed by bifenthrin 10EC (33.14 t/ha). The minimum onion bulb yield (25.71 t/ha) was obtained in the control, where no insecticide was applied against thrips. If onion thrips are not controlled, the damage they cause can reduce bulb yields by 9-25%. The highest incremental return over the control (Rs.83, 600/ha), net income (Rs.82, 913/ha) and maximum cost benefit ratio were also obtained in the treatment with dimethoate 40EC.

The Impact

Objective Premature infants have the highest risk of being hospitalized with respiratory syncytial virus (RSV) infections. Palivizumab is the only licensed agent for RSVhospitalization (RSVH) prophylaxis in infants born at < 35 weeks of gestational age (wGA). In 2016, the Italian Drug Agency (Agenzia Italiana del Farmaco [AIFA]) has restricted the eligibility for reimbursement to infants at high risk of RSVH, ruling out palivizumab administration for infants born at > 29 wGA. The aim of the present study was to compare the incidence of RSVH in two consecutive epidemic seasons (2015–2016 vs. 2016–2017), that is, before and after the new AIFA recommendations on palivizumab eligibility. Study Design This was a noninterventional retrospective cohort study conducted at three neonatal intensive care units (NICUs) in northern Italy. Infants born at 29 and 35 wGA between March 15, 2015 and March 14, 2017 were enrolled for this study. Electronic medical charts were reviewed and parents were interviewed by telephone. Data were collected on neonatal course during NICU stay, palivizumab administration, and hospitalizations related to respiratory infections during the 1st year of life, comparing the infants born in season 1 with season 2. Results Of 632 eligible infants, data were available for 536 (262 in season 1 and 274 in season 2). Overall, RSVH occurred 1.9 and 5.1% in infants in seasons 1 and 2, respectively (odds ratio [OR] = 2.77; 95% confidence interval [CI]: 0.98–7.8, p = 0.045). When the analysis was limited to patients not exposed to palivizumab, RSVHs were recorded for 1.8 and 5.9% infants in seasons 1 and 2, respectively (OR = 3.42; 95% CI: 0.96–12.20, p = 0.045). It is noteworthy that the incidence of hospital admissions for respiratory viruses other than RSV did not differ between the two seasons. Conclusion Restricting eligibility for palivizumab reimbursement led to a significant increase in RSVH but had no impact on hospitalizations for other respiratory viruses. Future decisions on palivizumab prescription and coverage rules should be driven by a careful assessment of the cost-benefit ratio.

An experiment was conducted at Regional Agricultural Research Station, Parwanipur, Bara for 38 days to test the effect of Khesari leaves inclusion in broiler feed and its effect on growth performance. Altogether 135 day-olds Cobb-500 broiler birds were procured from Shivam Hatchery, Birgung and divided into 3 treatments with 3 replications (15 birds in each replication) by using completely randomized design. Concentrate feed was purchased from Posak Feed industry, Birgung. Control group (T1) was fed without inclusion of Khesari leaves and whereas T2 and T3 groups were fed 5% and 10 % Khesari leaves added feed respectively. Diet replaced with 5 % and 10 % Khesari leaves were offered from 14th day of trial to T2 and T3 broilers group respectively. Experimental birds were provided adlib amount of grower feed (B1) for 21 days and that after finisher feed (B3) for 21 days and had easily access to drinking water. Feed intake was recorded daily and body weight gain was measured in 7 days interval. Experiment revealed that highest weight gain was observed in T3 (2.55 kg) followed by T1 (2.48) where inclusion of 10 % Khesari leaves and normal feed respectively, which was also significant among diet groups. Similarly, highest cumulative feed intake was also observed for T3 (4.23 kg) followed by T1 (3.90 kg) which was also significant among diet groups. Experiment suggested that further study should be carried out to precise the appropriate level of organic acids inclusion and higher cost benefit ratio.

Dentoalveolar surgery is probably the major risk factor for MRONJ and for other complications following a tooth extraction, especially in patients affected by systemic diseases. The aim of this retrospective study is to evaluate whether a PRF plug inserted in the post extraction socket can prevent the onset of MRONJ. The patients were divided into two groups according to the surgical protocol that included the insertion or not of the PRF following the extraction and all the anamnestic, and clinical data were analyzed. In the control group, 5 patients developed MRONJ (19.23%) while in the study group, any case of MRONJ was reported. In the control group, patients who developed MRONJ had a CTX with less than 100 pg/mL (5 high-risk patients, Spearman’s rank r = .547 , p < .001 ). The use of platelet concentrates in patients with high risk of MRONJ is a user-friendly technique with an excellent cost-benefit ratio in oral surgery.

The experiment was conducted to study the performance of Kenguri ram lambs in two different production systems in an organized farm in Koppal district of Karnataka. Sixty weaned Kenguri ram lambs of uniform body weight and morphological characteristics were selected and randomly allocated to two rearing systems (R1 and R2) of thirty each. The lambs of R1 were considered as control group, they were on grazing for 8 hours daily from 9.00 am to 5.00 pm and fed paddy straw during night hours. The lambs of R2 were reared in intensive system and fed commercial concentrated feed (IS. 5569. 1970) (17% DCP and 70% TDN) from three to nine months. The animals were provided concentrate feed based on their age. The green grass like Congo signal, hybrid Napier and paddy straw were also provided ad libitum along with clean, potable drinking water in the stall. The comparative economics of both the groups was worked out by comparing the expenditure incurred and returns obtained from the selling of lambs. The average live weight obtained in R2 was significantly higher (p less than 0.01) than R1. The respective output price, net profit and cost- benefit ratio was higher in R2 compared to R1. Thus the Kenguri lambs can be reared in intensive system with better income in semi-arid conditions of Karnataka.

Purpose Semi-occluded vocal tract (SOVT) exercises with tubes or straws have been widely used for a variety of voice disorders. Yet, the effects of longer periods of SOVT exercises (lasting for weeks) on the aging voice are not well understood. This study investigated the effects of a 6-week straw phonation in water (SPW) exercise program. Method Thirty-seven elderly subjects with self-perceived voice problems were assigned into two groups: (a) SPW exercises with six weekly sessions and home practice (experimental group) and (b) vocal hygiene education (control group). Before and after intervention (2 weeks after the completion of the exercise program), acoustic analysis, auditory–perceptual evaluation, and self-assessment of vocal impairment were conducted. Results Analysis of covariance revealed significant differences between the two groups in smoothed cepstral peak prominence measures, harmonics-to-noise ratio, the auditory–perceptual parameter of breathiness, and Voice Handicap Index-10 scores postintervention. No significant differences between the two groups were found for other measures. Conclusions Our results supported the positive effects of SOVT exercises for the aging voice, with a 6-week SPW exercise program being a clinical option. Future studies should involve long-term follow-up and additional outcome measures to better understand the efficacy of SOVT exercises, particularly SPW exercises, for the aging voice.

Abstract. This study measured the effect of emotional states on lexical decision task performance and investigated which underlying components (physiological, attentional orienting, executive, lexical, and/or strategic) are affected. We did this by assessing participants’ performance on a lexical decision task, which they completed before and after an emotional state induction task. The sequence effect, usually produced when participants repeat a task, was significantly smaller in participants who had received one of the three emotion inductions (happiness, sadness, embarrassment) than in control group participants (neutral induction). Using the diffusion model ( Ratcliff, 1978 ) to resolve the data into meaningful parameters that correspond to specific psychological components, we found that emotion induction only modulated the parameter reflecting the physiological and/or attentional orienting components, whereas the executive, lexical, and strategic components were not altered. These results suggest that emotional states have an impact on the low-level mechanisms underlying mental chronometric tasks.

SummaryNuclear cardiological procedures have paved the way for non-invasive diagnostics of various partial functions of the heart. Many of these functions cannot be visualised for diagnosis by any other method (e. g. innervation). These techniques supplement morphological diagnosis with regard to treatment planning and monitoring. Furthermore, they possess considerable prognostic relevance, an increasingly important issue in clinical medicine today, not least in view of the cost-benefit ratio.Our current understanding shows that effective, targeted nuclear cardiology diagnosis – in particular for high-risk patients – can contribute toward cost savings while improving the quality of diagnostic and therapeutic measures.In the future, nuclear cardiology will have to withstand mounting competition from other imaging techniques (magnetic resonance imaging, electron beam tomography, multislice computed tomography). The continuing development of these methods increasingly enables measurement of functional aspects of the heart. Nuclear radiology methods will probably develop in the direction of molecular imaging.

SummaryChanges in platelets in 48 patients with uterine myoma before and after hysterectomy with and without ovariectomy were examined. Bilateral ovariectomy in 25 cases (ovariec-tomized group) and unilateral or non-ovariectomy in 23 cases (control group) were performed at the hysterectomy. Platelet count and an appearance rate of secondary aggregation decreased at one day after and increased at one week after the operation, similarly in both the ovariectomized and the control group. The appearance rate of secondary aggregation was reflected in an intensity of aggregation at 5 min after the addition of reagent to PRP. At one month after the operation, the appearance rate of secondary aggregation induced by 3 μM ADP showed a statistically significant decrease in comparison with the preoperation value (P <0.05) and the enhancement of 5-min aggregation was still observed in the control group, while ceased in the ovariectomized group. The difference between the two groups was significant (P < 0.05). There was almost no change in the speed and intensity of primary and secondary aggregation during the observation period. No significant differences in collagen-induced aggregation were noted between the two groups. The results suggest that ovarian hormones, mainly estrogen, facilitate platelet activation which is mediated by the so-called secondary aggregation.
