Consecutive weekly observations on the neutrophile, the basophile, and the eosinophile counts of the peripheral blood were made on 5 groups of normal rabbits, a total of 45 animals, during a period of 20 months from October, 1927 to July, 1929. Individual groups were examined 8 to 35 weeks. In the case of the 4 groups followed 13 to 35 weeks, the general trend of the neutrophile cells was towards increased mean values; with the group followed 8 weeks, decreasing values were found. An increase in the mean values of the basophile cells was observed in the two groups of rabbits followed in 1927–28; in the groups of 1928–29, the mean values decreased. The mean values of the eosinophile cells showed no definite trends but the findings were characterized by abrupt and marked fluctuations. The periods of greatest irregularity in mean neutrophile and eosinophile values occurred in the fall and the late winter and spring months of both years, but in the case of the basophiles, the irregularities were distributed throughout the first year and occurred chiefly in the winter months of the second year. The major trends and many of the minor fluctuations as well which were observed in the mean cell values of one group of rabbits were also generally seen in another group examined during the same months. The general levels of the neutrophile, the basophile, and the eosinophile mean values in the groups examined during 1927–28 were higher than in the groups of 1928–29.

The Mean

Consecutive weekly observations on the lymphocyte and monocyte counts of the peripheral blood were made on 5 groups of normal rabbits, a total of 45 animals, during a period of 20 months from October, 1927 to July, 1929. Individual groups were examined 8 to 35 weeks. The results are analyzed on the basis of the mean group values of each week. In the case of the 4 groups followed 13 to 35 weeks, there was a general tendency for the lymphocyte mean values to become increased; with the group observed 8 weeks, the level of mean values showed little change. The general trend of the monocyte mean values was also in the direction of higher levels but it was less pronounced than that of the lymphocytes. The period of greatest irregularity in the mean values of the lymphocytes was in the late winter and spring months of both years. With the monocytes, periods of fluctuating values occurred in the fall of 1927, the spring and early summer of 1928, and in the late winter, spring, and early summer of 1929. There was a certain degree of parallelism in the case of two groups examined during the same months with respect to the direction and time of occurrence of a change in the level of lymphocyte and monocyte mean values. The general levels of lymphocyte and monocyte mean values in the groups examined during 1927–28 were higher than in the groups of 1928–29. The results based upon the trends of mean group values obtained from consecutive weekly observations showed no evidence of a consistent numerical relationship between lymphocytes and monocytes.

Consecutive weekly observations on the total white cell count of the peripheral blood were made on 5 groups of normal rabbits, a total of 45 animals, during a period of 20 months from October, 1927 to July, 1929. The duration of individual group examinations varied from 8 to 35 weeks. In the case of 4 groups followed 13 to 35 weeks, the general trend of the total white cell means was toward increasing values; with the group followed 8 weeks, the means were maintained at a constant level. The changes in the levels of the granular cell means were usually accompanied by changes in a similar direction of the non-granular cell means. In the case of 3 of the 4 groups followed for the longest periods, the greatest relative alterations occurred in the non-granular cells. The fluctuations in the mean values of the total white cells and of the granular and the non-granular cells which were observed in one group of rabbits, were also generally observed in another group examined during the same months. The period of greatest irregularity in the mean values of the total white cell means and of the granular and the non-granular cell means as well, occurred during the late winter and spring months of both years. The general level of the total white cell mean values in the groups examined during 1927–28 was higher than that of the groups observed during 1928–29. A similar difference was found in the granular and non-granular mean values but it was somewhat less marked in the case of the granular cells.

The level of folic and folinic acid in whole blood was assayed in 373 healthy infants from birth to one year. Folic acid was high at birth and dropped gradually over the first 8 postnatal weeks. The mean value for the remainder of the first year was significantly below the adult mean. Folinic acid was likewise high at birth and dropped parallel with the folic acid. However, following the initial drop, folinic acid mean values remained well above the adult mean. Folic and folinic acid values were higher in breast-fed than in artificially fed infants and lower in infants whose economic status was poor than in babies belonging to families of higher income.

PurposeTo describe the long-term anatomical and functional results of surgery for retinal detachment (RD) associated with stage 4 retinopathy of prematurity (ROP) and patient and surgery-related factors affecting postoperative success.DesignRetrospective case series at a single tertiary referral paediatric vitreoretinal practice.MethodsOne hundred and twenty-one eyes of 82 infants (40 female/42 male) who underwent lens-sparing vitrectomy (LSV) or lensectomy with vitrectomy surgery for stage 4A and 4B ROP at Gazi University Department of Ophthalmology between 2011 and 2016 were enrolled in this study. Patient characteristics including gestational age, birth weight, gender, stage of ROP at presentation, preoperative treatment (laser, anti-vascular endothelial growth factor (VEGF) or combined), anatomical and functional outcome and complications were recorded. The effect of birth weight, gestational age, presence of plus disease, preoperative treatment status, surgically induced posterior hyaloid detachment, postoperative vitreous haemorrhage and iatrogenic retinal tear formation on anatomical and functional results was evaluated.Results61.2% of the eyes were stage 4A and 38.8% were stage 4B ROP. The mean follow-up was 24.5 months. 18.2% of the eyes had no preoperative treatment. Anatomical success was 86.5% for stage 4A and 68.1% for stage 4B at the first year, 91.7% for stage 4A and 69.4% for stage 4B at the second year, and 95.8% for stage 4A and 57.9% for stage 4B at the third year. Functional success was 85.1% for stage 4A and 65.9% for stage 4B at the first year, 89.6% for stage 4A and 61.1% for stage 4B at the second year, and 87.5% for stage 4A and 57.8% for stage 4B at the third year. The mean visual acuity was 1.12±0.34 logarithm of the minimum angle of resolution (logMAR) for stage 4A and 1.34±0.32 logMAR at the 3-year follow-up duration (p>0.05). There was preoperative plus disease in 59.5% of the eyes. Subsequent retinal surgeries were required in 17.4% of the eyes. Presence of plus disease and absence of preoperative treatment, iatrogenic retinal tear formation and postoperative vitreous haemorrhage were found to have significant negative effects, while surgical induction of posterior hyaloid detachment and sparing the lens intraoperatively affected the anatomical and functional results positively.ConclusionsSurgery for stage 4 ROP-associated RD resulted in encouraging anatomical and functional outcomes and the results are even better in eyes with preoperative (laser/anti-VEGF) treatment, LSV and surgically induced posterior hyaloid detachment.

1. Plants of S.48 timothy were established on a 1 ft square pattern for production of seed. Two series of plots, one irrigated and one not irrigated, were treated with three levels of applied nitrogen: 0 (NO), 87 (Nl) and 261 (N2) lb N per acre (0, 97·5 and 292·5 kg N/ha) per annum, for 3 years. In this, the first of two papers, only vegetative aspects of growth are considered. Since the irrigation treatment started only 2 weeks before most of the data were recorded, effects of irrigation on vegetative growth were generally small.2. The number of tillers per plant was increased by application of nitrogen; the lower increment was more effective than the additional nitrogen in the higher dose.3. The weight of tillers per plant was increased by nitrogen at both levels of application. The mean weight of each tiller was increased by nitrogen after the first year, predominantly in the N 2 treatment. In the second year, irrigation also increased the weight per tiller.4. The weight of roots per plant was significantly affected by application of nitrogen. In the first year, the weight was increased by nitrogen in irrigated plots; in the second year the roots were significantly heavier in the Nl treatment than in N0 and N2 treatments, where weights were similar; the same situation existed in irrigated plots in the third year, but in non-irrigated plots the weights of roots were similar in N1 and N2 treatments and were heavier than in the N0 treatment. Irrigation had positive effects on the weight of roots in the first and second years.

A study was conducted from 1980 to 1982 on the diet and condition of bobcats, Lynx rufus, in the province of Nova Scotia. Skinned carcasses were provided by trappers, hunters, fur buyers, and taxidermists. The autumn–winter diet was determined from analysis of 1099 stomachs. Canine teeth were sectioned and aged to group the bobcats into three age-classes: juvenile, yearling, and adult. Snowshoe hare, Lepus americanus, occurred most frequently as a prey item, followed by white-tailed deer, Odocoileus virgìnianus, and small mammals. The mean weights of hare and deer consumed per feeding were similar. Male bobcats consumed deer more frequently and in larger quantities than did females. Adults consumed deer more frequently and in larger quantities than did juveniles. Bobcats harvested in the first year of the study (1980–1981) consumed deer more frequently than did those harvested in the second year (1981–1982), while hare population levels were found to be lower in the first year than in the second. A condition index was developed by dividing the sum of the weights of mesenteric, kidney, and sternum fat by the weight of the skinned carcass. The groups (males, adults, and specimens harvested in 1980–1981) that more frequently consumed deer were found to be in the best condition.

Feedback Informed Treatment

Abstract: Aim, Methods, Results, DiscussionAim: This paper presents analyses of outcome data for 317 therapists treating 14,161 patients over a three-year period to determine if therapists’ effect sizes increased over time. Each therapist treated at least 5 patients in each of their first two years of using outcome measures. Multiple outcome questionnaires were employed. All measures also included a brief alliance scale administered concurrently. Method: A severity adjusted effect size was calculated for each patient using intake scores and diagnostic group as predictors. The mean severity adjusted effect size for each therapist was calculated for their first and second years of using the outcome tools. This was done using a hierarchical linear model to control for sample size in each year, with a minimum sample of 5 cases in each year. Therapist engagement in receiving feedback was measured by counting the number of times the therapist logged into the online platform to view their results in each of the two years.Results: Therapists who logged in the view their data at least 24 times in the second year (n=123; 37%) averaged .92 effect size compared to .82 effect size for those seen by therapists who reviewed their results less frequently (n=214; 63%). Login frequency during the first year was not predictive of effect size during the second year. Discussion: The data provides evidence that effect sizes can trend upwards with measurement and feedback. Therapists’ engagement in receiving feedback appears to increase the likelihood of effect size gain.

ABSTRACT The use of organic fertilizers can increase the production of forest species for the extraction of wood from monoculture stands or integrated systems. This study aimed to evaluate the effect of applying doses of sheep manure on the biometric traits of Mimosa caesalpiniifolia (‘sabiá’) in a silviculture system in an area previously occupied by native degraded pasture in an Albaquult. The experimental design was randomized blocks with four repetitions, with treatments corresponding to five doses of sheep manure per plant: 0, 2, 4, 8, and 12 kg in the first year, while in the second year the double of the doses (0, 4, 8, 16 and 32 kg per plant) were applied as topdressing under the canopy. The following biometric variables were evaluated: height (H); root collar diameter (RCD); diameter at breast height (DBH); above-ground dry weight (AGDW); accumulation of nutrients (aerial part); and soil fertility. The plants were responsive to the organic fertilization regarding the variables H, DBH, and AGDW. The sheep manure increased the mean values of pH, P, K, Ca, Mg, SB, CEC, BS, S-SO4 2- and Zn, and reduced the potential acidity in the 0-0.20 m soil layer. The organic matter variable increased up to the dose of 13.70 kg per plant. The accumulation rates of macro and micronutrients in the ‘sabiá’ plants were N > Ca > K > Mg > P > S and Fe > Mn > B > Zn > Cu, respectively.

Background: Newly admitted medical students experience a different curriculum, which can be a stressor and may be the reason of stress during student life. Stress may affect physiological, psychological and cognitive functions of the students. Aims and Objective: Aim of the study was to assess the effect of academic stress on physical activity level and cognitive functions in first year medical students. Materials and Methods: This observational study was conducted on 30 healthy newly admitted medical students (18 -25 years). The data was collected thrice, baseline, after two months and after four months. Stress was assessed by using DASS and Cohen perceived stress scale (PSS). GPAQ was used to estimate the physical activity level. And cognitive functions were assessed by using subjective method (MMSE questionnaire) and objective method (P300). Results: No significant difference of mean values of age, height, weight, BMI, physical activity level, DASS score, PSS and P300 latency were observed over the time to which recording was taken. The mean score of PAL represents the high physical activity. But the score of DASS and PSS represent severe and moderate stress level respectively. The significant difference was seen in the mean values of MMSE score and P300 amplitude over the time to which recording taken. Conclusion: The present study results we can conclude that students have stress during their academic period. And this stress might be helpful in potentiating the cognitive functions with the optimum physical activity.

ObjectivesEmpathy education is very important for medical students. There is little research on the influence of early clinical practice on the development of empathy and other aspects of professionalism in medical students. The aim of this study was to compare the self-reported empathy levels of first-year and second-year undergraduate medical students before and after their early clinical contact curriculum.SettingThe study was conducted at the Shanghai University of Medicine & Health Sciences, Shanghai, China.ParticipantsA total of 257 undergraduate medical students participated in the study. The 154 first-year students were studying in 10 community-based teaching hospitals, and the 103 second-year students were studying in 3 university-affiliated hospitals.Primary and secondary outcome measuresPrimary measures: the Jefferson Scale of Empathy—Student version (JSE-S) was compared between students of different sexes and in different academic years before their early clinical contact course. Secondary measures: comparisons were made after they finished the curriculum 3 weeks later.ResultsA total of 219 of 257 students responded (85.21% response rate), and 214 answers could be analysed (135 first-year and 79 second-year students; 120 female and 94 male individuals). No significant differences in the empathy scores before early clinical contact were observed between students of different sexes and in different academic years. After early clinical contact, the mean JSE-S score of the participants was significantly higher than the mean score at the beginning of the curriculum.ConclusionsEmpathy-focused training during early clinical contact can improve the empathetic capacity of undergraduate medical students. Fostering empathetic attitudes among undergraduate medical students is necessary for the early stage of their medical education. Further research is needed on the long-term effects of empathy-focused education in entry-level medical students.
