Objectives
We aimed to evaluate the outcomes of Petals: a charitable organisation in Cambridgeshire. Petals provides counselling for women and couples who have suffered perinatal bereavement, or trauma during pregnancy or birth. This paper attempts to evaluate the effect of counseling interventions at this difficult time.
MethodsOutcomes were recorded in 42 patients using the CORE (Clinical Outcomes in
Routine Evaluation) system. CORE was developed to assess the effectiveness of psychological therapies. CORE-OM (CORE Outcome Measure) involves a
questionnaire that assesses subjective well-being, symptoms/problems, function, and risk to self and others. The CORE-OM questionnaire was completed before and after the counselling sessions.
ResultsThe CORE-OM scores were summated into a global representation of severity.
Severity decreased in all patients. Symptoms of psychological pathology were also decreased in all cases.
ConclusionA review of the available literature indicates that little is known about the efficacy of therapy for perinatal bereavement and trauma. These original data suggest convincing efficacy and benefits, but the numbers involved are small. Further trials with greater sample sizes are required.

Summary
Endophytes are microorganisms that colonise the internal compartments of host plants without harming the host. In many cases, endophytic bacteria have been shown to provide several beneficial effects to their host plant, including growth-promoting activity, modulation of plant metabolism and phytohormone signalling that leads to adaptation to environmental abiotic or biotic stresses. Endophytic bacterial community structure is influenced by plant genotype, soil type, abiotic and biotic factors, such as environmental conditions and microbe–microbe/plant–microbe interactions. In addition, agricultural management practices, such as soil tillage, crop rotation, and fertiliser and pesticide applications have a major effect on the function and structure of the soil, rhizosphere and endophytic bacterial communities. Oilseed rape (Brassica napus L.) is an important break crop in cereal crop rotation and can significantly reduce the rate of ‘take-all’ fungal disease (Gaeumannomyces graminis var. tritici) and, as a result, improves the yield of subsequent cereal crops. Additionally, oilseed rape is the world’s third largest source of vegetable oil used for human nutrition and as a source of oil for biodiesel production. Therefore, the promotion of agricultural practices that maintain the natural diversity of B. napus endophytic bacteria is receiving attention as an important element for a sustainable agricultural system that ensures crop productivity and quality while reducing inputs. This chapter reviews the existing literature on the role of endophytic bacteria in oilseed rape crop production, agricultural factors influencing oilseed rape bacterial diversity and discusses how meta-omics is enhancing our understanding of the endophytic bacteria and their function.

Cadmium sulfide mineralization occurs in grey-black shales of the late Mesoproterozoic Stoer Group, Torridonian Supergroup, northwest Scotland. Cadmium is strongly redox-controlled, and normally concentrated in anoxic marine sediments or epigenetic mineralization involving organic matter. However the Stoer Group was deposited in a terrestrial environment, including lacustrine deposits of shale. At the limited levels of atmospheric oxygenation in the Mesoproterozoic (∼10% of present), the near-surface environment could have fluctuated between oxic and anoxic, allowing fractionation of Cd from Zn, and the formation of Cd sulfide rather than Cd-bearing sphalerite. This occurrence emphasizes the importance of the Stoer Group as a record of the Mesoproterozoic terrestrial environment.

We propose a 3D-printable soft, stretchable, and transparent hydrogel-elastomer device that is able to detect simulated ‘nerve’ signals. The signal is passed to a conductive hydrogel electrode through a non-contact method of capacitive coupling through polydimethylsiloxane (PDMS). We demonstrate that the device is able to detect sinusoidal waveforms passed through a simulated ‘nerve’ made from conductive hydrogel over a range of frequencies (1 kHz – 1 MHz). Analysis of signal detection showed a correlation to the electrode contact area and a Vin/Vout of larger than 10%. This provides the framework for the future development of a soft, 3D-printable, capacitive coupling device that can be used as a cuff electrode for detecting peripheral nerve signals.

The literature suggests that grain number largely determines and as such limits yield in barley. Many of the reported studies were conducted in relatively low-yielding environments and it is unclear if grain number is also a limiting factor in high-yield potential climates. Nor is it known with certainty what physiological or morphological traits must be targeted in order to increase grain number. A detailed programme of assessments was carried out on replicated field plots of a two-row spring barley variety (Hordeum vulgare L. cvar Quench) at three sites (Carlow, Wexford and Cork) in Ireland from 2011 to 2013. Plots were managed for high yield potential as per current best farm practice. Destructive sampling and in-field assessments were carried out at approximately weekly intervals from emergence onwards to gather growth, development and yield component data. Across nine site/seasons, grand means of 8·52 t/ha for yield, 18 419 for grain number/m2 and 46·41 mg for mean grain weight were achieved. Grain number/m2 accounted for most of the variation in yield and ear number/m2 accounted for most of the variation in grain number/m2. Early-season maximum shoot number/m2 had little influence on harvest ear number/m2. The period over which final ear number was determined was more flexible than the literature suggests, where the phases of tiller production and senescence varied considerably. Significant post-anthesis re-tillering occurred following the initial phase of shoot mortality at two out of nine site/seasons, but this appeared to contribute little to yield. Yield was positively associated with the proportion of shoots surviving from an early season maximum to a mid-season minimum (R2 = 0·62). Shoot size and weight at the beginning of stem extension had the largest influence on shoot survival, indicating that crop condition and hence growth and development pre-stem extension may be more important for shoot survival than growth and development during the stem extension period. Achieving high shoot numbers of adequate size and weight at the beginning of stem extension may be an appropriate target for establishing a high-yield potential crop.

The optimization of management practices for oats is hindered by a lack of knowledge of the critical phenological phases at which management should be focussed. The objective of the present review was to identify the yield-limiting phases in the growth of the oat crop in order to optimize management and to maximize yield. The methodology employed was to identify characteristics associated with either the pre-anthesis grain number determination phase or with the post-anthesis grain filling phase. Characteristics associated with the pre-anthesis phase were identified as a positive linear relationship between yield and grain number, in addition to insensitivity of grain weight to changes in assimilate supply. Characteristics associated with the post-anthesis grain filling phase were identified as an absence of a relationship between yield and sink size (grain number) and changes in grain weight in response to changes in assimilate supply. Data was taken from published literature. Yields of both winter- and spring-sown hulled oats increased linearly with grain number showing a strong influence of grain number on yield. Grain weight of both winter- and spring-hulled oats, however, decreased with increasing grain number suggesting that competition for assimilates may exist at high grain number. Further evidence of the influence of assimilate supply on grain yield was obtained from several studies which showed that yield increased with leaf area duration as well as from studies where grain weight was found to decrease after reductions in assimilate supply per grain, whereas grain weight increased when assimilate supply to grain was increased. Oat crops also feature a grain abortion mechanism when assimilate supply is constrained. Yield of naked oats increased with grain number before reaching a plateau, a trend which suggests source limitation at high grain numbers. The available evidence suggests that yield is primarily determined by grain number determination but that grain yield is also potentially limited by assimilate availability in the post-anthesis period. It is recommended that crop management strategies for oats should aim both to increase grain number in the pre-anthesis period but also prolong the grain filling period after anthesis. Such a post-anthesis strategy should both reduce the possibility of yield being limited by assimilate availability and compensate for the production of smaller grains at higher grain numbers.

With the increased availability of radioisotopes and their application to the study of insect behaviour and dispersal, the possibility of using a radio-active tag on grasshoppers was investigated. Preliminary studies on the distribution of radio-active phosphorus (P32) in Melanoplus mexicanus mexicanus (Sauss.) and Camnula pellucida (Scudd.) were carried out by Murray (1949) and Fuller (1950). The P32, in the form of phosphate ion, was placed on food plants in drop form, or the leaves were dipped in an aqueous solution containing the phosphate ion. When this was fed to the grasshoppers over 50 per cent of the activity was excreted, but the amount retained was distributed throughout the body. The highest activities were recorded for the thorax and the metathoracic legs. The radio-activity apparently had no ill effects on the grasshoppers. However, more specific data were required to determine how well the applied activity is taken up and how long it is retained.

Bugher and Taylor (1949) and Hassett and Jenkins (1949) reared highly radio-active adults of Aedes aegypti (L.) from larvae kept in a solution of radioactive phosphorus. Jenkins and Hassett (1949) obtained radio-active adults of Aedes pullatus (Coq.) and Aedes excrucians (Wlk.) with an average radio-activity of 4,300 counts per minute by rearing larvae in ponds to which radio-active phosphorus was added. Jenkins and Hassett (1951), with sub-Arctic mosquitoes, chiefly Aedes communis (Deg.), produced adults with radio-activity from 100 to 3,770 counts per minute from larvae reared in vats of P32 solution; adults released and recaptured in the field had an average radio-activity of 915 counts per minute. Thurman and Husband (1951) tagged larvae with P32 and released 400,000 adult mosquitoes in California. Of this number, 249 adults were recaptured at distances up to 1⅞ mi. downwind and 1½ mi. upwind from the release point. Yates et al. (1951) and Hassett and Jenkins (1951) produced radio-active adults of Aedes sticticus (Meig.) and Aedes aegypti (L.) by allowing them to feed on P32 solutions; the radio-activity was readily detectable with a Geiger counter for as long 13 days.

Brief assessments of general cognitive ability are frequently needed by neuropsychologists, and many methods of estimating intelligence quotient (IQ) have been published. While these measures typically present overall correlations with the Wechsler Adult Intelligence Scale (WAIS) Full Scale IQ, it is tacitly acknowledged that these estimates are most accurate within 1 standard deviation of the mean and that accuracy diminishes moving toward the tails of the IQ distribution. However, little work has been done to systematically characterize proxy measures at the tails of the IQ distribution. Additionally, while these measures are all correlated with the WAIS, multiple proxy measures are rarely presented in one manuscript. The current article has two goals: (1) Examine various IQ proxies against Wechsler Adult Intelligence Scale (Third Version) scores, showing the overall accuracy of each measure against the gold standard IQ measure. This comparison will assist in selecting the best proxy measure for particular clinical constraints. (2) The sample is then divided into three groups (below, average, and above-average ability), and each group is analyzed separately to characterize proxy performance at the tails of the IQ distribution. Repeated measures multivariate analysis of variance compares the different proxy measures across ability levels. All IQ estimates are represented in tables so that they can be examined side by side.

The effects of the anti-gibberellin triazole metconazole on yield, lodging resistance, seeds/m2 (sink size) and rooting in the presence of negligible amounts of disease were investigated using five multi-site experiments carried out in the UK between 1999 and 2007. The green area index (GAI) of the crop at the time of application had the greatest influence on the yield response across 173 comparisons between metconazole-treated and untreated crops. Crops with a GAI in March (growth stage (GS) 3·3–3·5 ‘green bud’) of 0·8–2·8, which represented moderate to large sized UK commercial crops, had an average response of +0·21 t/ha to metconazole applied at the full recommended rate of 1·2 litres/ha. Crops with a GAI of less than 0·8, which represented small commercial crops, had an average response of −0·14 t/ha. Applications between green bud and early flowering gave the greatest yield increase. Positive yield responses were associated with a reduction in lodging, or more seeds/m2, or a combination of both. The proportional area lodged was reduced by 0·1 for each 50 mm reduction in crop height (R2=0·60; P<0·001). Across six field trials, metconazole applied in spring increased root length density between soil depths of 0·40 and 1·00 m from an average of 0·478 to 0·601 cm/cm3 (P<0·05). It was estimated that this could increase yield by 0·2–0·3 t/ha in a dry season. The results show that the growth regulatory properties of metconazole can be used to improve several key aspects of growth that are believed to restrict current farm yields.

Falls have a significant impact upon independent living ability in older people, with fall-related fractures one of the leading predictors of having to move into assisted living facilities. The loss of independence associated with a severe fall is often accompanied by a decline in physical, social, emotional and economic well-being. Rehabilitation programmes to restore functional ability following a fall have a greater chance of success if they adopt a multi-disciplinary approach and, if appropriate, are conducted in the patient's own home. Additional multi-component interventions that improve confidence and reduce the risk of subsequent falls may confer benefits by assisting individuals independently to perform activities of daily living.

Hepcidin plays a major role in iron homeostasis, but understanding its role has been hampered by the absence of analytical methods for quantification in blood. A commercial ELISA has been developed for serum prohepcidin, a hepcidin precursor, and there is interest in its potential use in the clinical and research arena. We investigated the association between serum prohepcidin concentration and iron absorption in healthy men, and its relationship with iron status in men carrying HFE mutations, hereditary haemochromatosis patients, and pregnant women. Iron absorption was determined in thirty healthy men (fifteen wild-type, fifteen C282Y heterozygote) using the stable isotope red cell incorporation technique. Iron status was measured in 138 healthy men (ninety-one wild-type, forty-seven C282Y heterozygote), six hereditary haemochromatosis patients, and thirteen pregnant women. Mean serum prohepcidin concentrations were 214 (sd 118) ng/ml [208 (sd 122) ng/ml in wild-type and 225 (sd 109) ng/ml in C282Y heterozygotes] in healthy men, 177 (sd 36) ng/ml in haemochromatosis patients, and 159 (sd 59) ng/ml in pregnant women. There was no relationship between serum prohepcidin concentration and serum ferritin in any subject groups, nor was it associated with efficiency of iron absorption. Serum prohepcidin is not a useful biomarker for clinical or research purposes.

Oilseed rape yields on farms have not increased in several countries, including the UK, since the mid 1980s. This may be because the yield potential for the environment in these countries has been reached, or due to a lack of genetic improvement, or due to changes in the environment of the growing crop caused by crop management practices. The present paper investigates which of these factors may be causing the yield of farm crops in the UK to remain at 3 t/ha. The yield potential for the UK that would be possible by combining the best characteristics that have been observed with the best crop management is estimated to be significantly greater than average farm yields at 6·5 t/ha (90 g/kg moisture content). In order to achieve 6·5 t/ha, a crop would have a flower cover of less than 0·4 to facilitate the production of 130000 seeds/m2. Seed filling must last 46 days and have a solar radiation use efficiency of 0·75 g of seed/MJ. A tenth of the yield must come from stem reserves and the seed weight must be 5·0 mg. All of these characteristics have been achieved; therefore the challenge lies in combining these traits within the same crop. The ultimate yield potential for water retentive soils in the UK is estimated at 9·2 t/ha. This would require new characteristics to be bred into the crop and represents a long-term target. In the UK, new oilseed rape varieties are introduced each year and the yield of these varieties under optimum growing conditions is estimated to have increased by 62 kg/ha/year between 1978 and 2005. Lack of genetic improvement is therefore unlikely to explain the halt in farm yields. There have been trends for farm crops to be grown in shorter rotations, established using minimal cultivations rather than ploughing and to receive less nitrogen fertilizer. Sulphur applications have increased, but probably have not kept pace with the reduction in deposition from the atmosphere. Fungicide applications to farm crops are less than applied to the variety testing system and are unlikely to offer complete disease control. It is concluded that a combination of these crop management factors has caused the halt in yield improvement on UK farms.

The results of recent trials for winter wheat (Triticum aestivum L.) have influenced farming practice in the UK by encouraging the use of lower seed rates. Spink et al. (2000) have demonstrated that, particularly if sown early, wheat can compensate for reduced plant populations by increased tiller production.
Results from seed-rate trials are usually analysed separately for each environment or each combination of environment and variety, and not combined into a single model. They therefore address the question of what the best seed rate would have been for each combination, rather than answer the more relevant question of what rate to choose for a future site. The current paper presents a Bayesian method for combining data from seed-rate trials and choosing optimum seed rates: this method can incorporate information on seed and treatment costs, crop value and covariates. More importantly, for use as an advisory tool, it allows incorporation of expert knowledge of the crop and of the target site.
The method is illustrated using two series of trials: the first, carried out at two sites in 1997–99, investigated the effects of sowing date and variety in addition to seed rate. The second was conducted at seven sites in 2001–03 and included latitude and certain management factors. Recommended seed rates based on these series vary substantially with sowing date and latitude.
Two non-linear dose-response functions are fitted to the data, the widely used exponential-plus-linear function and the inverse-quadratic function (Nelder 1966). The inverse-quadratic function is found to provide a better fit to the data than the exponential-plus-linear and the latter function gives estimated optimum rates which are as much as 40% lower. The economic consequences of using one function rather than the other are not great in these circumstances.
The method is found to be robust to changes in the prior distribution and to other changes in the model used for dependence of yield on sowing date, latitude, variety and management factors.

Plant characters that determine stem and root lodging were measured on 15 winter wheat cultivars at three UK sites between 2000 and 2002. A model of lodging was used to estimate stem failure wind speeds (resistance to stem lodging) and anchorage failure wind speeds (resistance to root lodging). The degree and type of natural lodging was also recorded in the plots and this correlated well with the stem and anchorage failure wind speeds. Only a weak correlation (R2=0·33) was observed between the stem and anchorage failure wind speeds for the 15 cultivars. This can be explained by the absence of genetic correlation between the plant characters that determine the stem and anchorage strength. There was a significant interaction between type of lodging (stem or root) and cultivar for failure wind speed (P<0·001). This showed that the difference between the resistances for root and stem lodging was not the same for all cultivars. Separate classifications for the stem and root lodging resistance of cultivars are developed that would allow the most appropriate crop management to reduce the risk of both types of lodging. Significant differences were found between cultivars for all lodging-related plant characters (P<0·05). These resulted in the cultivar range of the anchorage failure moment to be 110% of the overall mean. Stem failure moment, shoot and plant base bending moments had ranges of 37–49% of their overall means. Breeders should select for wide, deep root plates and wide stems with a high stem wall failure yield stress for the greatest improvement in lodging resistance.

The giant mole-rat Cryptomys mechowi exhibits an extreme reproductive division of labour. Reproduction in the colony is restricted to a single breeding pair. Non-reproductive individuals do not breed unless removed from the colony and paired with unfamiliar conspecifics. Circulating basal concentrations of luteinizing hormone (LH) as well as LH levels measured in response to a single exogenous gonadotropin hormone (GnRH) challenge are not significantly different between the reproductive and non-reproductive groups of either sex. Neither non-reproductive males nor females are physiologically suppressed at the level of the pituitary, as they do not exhibit a reduced pituitary secretion of LH or decreased sensitivity to hypothalamic GnRH. Rather, reproductive skew seems to result from an inhibition to mate with familiar conspecifics. Familiar individuals housed in the absence of the breeding pair did not breed, whereas pairing unfamiliar individuals of the opposite sex resulted in sexual activity and recruitment. The results from the giant mole-rat suggest that reproductive skew may result from a predominantly behavioural repression in non-reproductive females arising from an incest avoidance mechanism.

The effects of breeding season and reproductive status on female reproduction were investigated in the common mole-rat, Cryptomys hottentotus hottentotus, a co-operatively breeding rodent that exhibits seasonal breeding and a reproductive division of labour. Body mass, reproductive tract morphometrics, ovarian histology and plasma testosterone concentrations were studied in 80 females from 42 wild-caught colonies. Although the birth of offspring is restricted to the summer, qualitative analysis of ovarian histology revealed that females retained reproductive function during the winter non-breeding period. Seasonal differences were found in ovarian morphometrics and testosterone concentrations and are probably associated with the occurrence of pregnancy in reproductive females during the breeding period. The continuance of reproductive function during the non-breeding period in female common mole-rats parallels the situation in males, and is believed to be important in dispersal in C. h. hottentotus. The non-breeding period coincides with the period of maximal dispersal opportunities in the winter rainfall areas inhabited by the common mole-rat. Reproductive activation in dispersing animals may aid intersexual recognition, assist pair-bond formation and thereby facilitate independent reproduction. Reproductive and non-reproductive females exhibited a similar degree of reproductive function, and as for season, the only clear-cut status-related differences were associated with the occurrence of pregnancy in reproductive females. This absence of a physiologically well-defined suppression of reproduction in female common mole-rats is similar to the situation in males. Incest taboos between philopatric siblings may negate the need for a rigorous suppression of reproduction in subordinate colony members of this obligate outbreeder.

The experience and perception of effective sources of help of 101 schizophrenic patients were studied. A combination of professional help, social support, and self-coping efforts was listed as helpful. The more experiences patients had with the various sources of help, the better were their outcomes. Premorbid adjustment, exposure to the magnitude and nature of helpful sources, as well as the patients' own ability and motivation to make use of available helpful sources were thought to be important mediating variables for a better outcome. Apart from psychotropic medications, over half of the patients were not using any one of the sources of help mentioned. It remains an important research question whether or not schizophrenic patients may benefit from direct coaching in self-help skills in conjunction with making optimal use of professional and environmental supports.
