Australian Merino

The lifetime reproductive performances (5 annual cycles) of 2105 Merino ewes from a multiple bloodline flock (15 separate bloodlines) were used to determine the association between reproductive performance in early life (either at 2 or 3 years of age, or the combined information from both years) and later performance. Early life fertility was indicative of both the fertility and the rearing ability of ewes in later life. The relationship of the combined weaning performance at the first and second annual reproductive cycles with reproductive performance in later life suggested gains were possible in the current flock from culling with emphasis on low fertility and rearing ability. Ewes that were dry at 2 and 3 years of age subsequently reared only half as many lambs as ewes that had reared lambs at 2 and 3 years of age.

Hydrocephalus in early life can often be so successfully treated as to allow children to live and grow with normal intelligence. Whereas untreated hydrocephalus allows only unpredictable intelligence when arrested, a far better prognosis holds for treated hydrocephalus. In an analysis of 147 patients with hydrocephalus treated by valveregulated ventriculovenous shunt, IQ can be related to ultimate frontal cerebral mantle. We have sought to correlate late IQ with the nature of the presenting abnormality, the age at which treatment was instituted, and the adequacy of control of the hydrocephalus as reflected in growth of cerebral mantle. This analysis indicates that in certain specific situations, prognosis for good IQ is predictable. At the same time, the study suggests guidelines for adequacy of shunting and the urgency for early shunting to allow for maximum benefits.

Depressive Patients

The genetic evidence concerning affective illness of later life is still conflicting and the relationship of such conditions to the manic-depressive psychosis unclear. Kallman (1955) believed that, genetically, involutional melancholia bore a closer relationship to schizophrenia than to the manic-depressive psychosis. An increased risk for schizophrenia amongst the relatives of such patients was not observed by Kay (1959) and Stenstedt (1952). Both these writers do however describe a lower loading for manic-depressive psychosis than would be found amongst the relations of manic-depressive patients, though a much higher incidence than in the general population. Both Stenstedt and Kay assumed that they were dealing with a heterogeneous group of patients containing both psychotic and neurotic depressions.

SynopsisKaryograms prepared from ovarian and blastoderm cells of the parthenogenetic Australian Brown Vegetable Weevil demonstrate a consistent triploid condition with 30 chromosomes which can be grouped into 10 sets of homologues. Meiosis is replaced by a single mitotic-like division in which 30 univalent chromosomes, each composed of two chromatids, divide equationally between an ootid nucleus and a single polar nucleus. Prior to the differentiation of the oocytes a peculiar bouquet stage occurs in the cells of the end chamber of each ovariole, but the significance of this phase is not known. Arrested development in eggs from individuals of low fertility is investigated and the relationship of body size and chromosome number is discussed.

Infants who fail to grow much occur in the third month or fourth month of early life. Early breastfeeding of the ASI causes mothers not to give breast milk and cause infectious diseases that result in stunting in infants. The purpose of this research is to find out the relationship of early breastfeeding with nutritional status (PB/U) age 4-7 months in Ratu Samban Sub-district of Bengkulu City.  This research uses analytic observational with a cross-sectional design. The results showed the nutritional status of PB / U short category 18.3% and MP ASI early 66.7% while the statistical test showed probability (p) of 0.273 (p> 0.05).  There is no correlation between early breastfeeding of MP and nutritional status of PB / U age 4-7 months in Ratu Samban Sub-district of Bengkulu City. Need to do re-research a using Cohort method and with other variables.Bayi yang gagal tumbuh banyak terjadi pada bulan ketiga atau bulan ke empat awal kehidupan. Pemberian MP ASI dini mengakibatkan ibu tidak berusaha memberikan ASI dan menyebabkan terjadinya penyakit infeksi yang mengakibatkan stunting pada balita. Tujuan dari penelitian ini adalah untuk mengetahui hubungan pemberian MP-ASI dini dengan status gizi (PB/U) pada bayi usia 4-7 bulan di Kecamatan Ratu Samban Kota Bengkulu. Jenis penelitian ini menggunakan observasional analitik dengan desain cross sectional. Hasil penelitian menunjukan status gizi PB/U kategori pendek 18,3% dan MP ASI dini 66,7% sedangkan uji statistik menunjukkan nilai probabilitas (p) sebesar 0,273 (p > 0,05).  Tidak ada hubungan antara pemberian MP ASI dini dengan status gizi PB/U usia 4-7 bulan di Kecamatan Ratu Samban Kota Bengkulu . Hal ini berkaitan dengan pemberian makanan pendamping ASI sementara sebagai makanan prelaktal sebelum ASI ibu keluar dan diberikan dalam jumlah sedikit. Lebih baik dilakukan penelitian lanjutan dengan menggunakan metode Kohort dan dengan variabel lain.

The beneficial effect of creative activities on individuals’ subjective wellbeing has become a popular and academic given in recent years. Yet the creative processes occurring in a complex, non-drug intervention and their relationship with perceived beneficial effects on wellbeing are difficult to define. Health professionals, arts practitioners and commentators alike identify the need for the development of a multi-disciplinary vocabulary that reflects the interests and values inherent in this rapidly developing discipline. Newcastle University’s “Ageing Creatively” project was an 18-month pilot study to explore the relationship of creative arts interventions to wellbeing in later life (Adams, Thomas & Thomson, 2014). This paper presents the results of metaphor analysis in a series of exit interviews with 31 participants. One-to-one interviews were administered by telephone or in person by specialist, creative arts researchers and each interview was semi-structured using the CASP-12 questionnaire, which aims to measure quality of life in the third age (Sim et al., 2011). The Metaphor Identification Procedure was applied (double-blind) by hand to the transcribed corpus of c.93,000 words, inputted into MS Excel and then discursively coded with vehicles by the researchers. Two dominant vehicle groupings emerged that suggest subjective wellbeing amongst the participant group is conceptualized using the container image schema and the source-path-goal image schema. We therefore propose two systematic, novel metaphors — wellbeing is a container and wellbeing is a journey — as meaningful alternatives to Lakoff and Johnson’s conceptual metaphor wellbeing is wealth, especially in the search to better understand the relationship between creative activities and subjective wellbeing. Our findings suggest that systematic metaphor analysis may be usefully incorporated into the range of social science methodologies available for the measurement of subjective wellbeing.

The relationship of objectively measured sedentary time (ST), frequency of breaks in ST, and lower extremity function (LEF) was investigated in a diverse sample aged ≥ 70 years (n = 217). Physical activity (PA) was assessed by accelerometry deriving moderate-vigorous PA (MVPA) minutes per registered hour (MVPA min · hr−1), registered ST (ST min · hr−1), and breaks in ST min · hr−1 (breaks · hr−1). LEF was assessed by the Short Physical Performance Battery. Univariate associations with overall LEF were MVPA (r = .523), ST (r = −.499), and breaks (r = .389). Adjusted linear regression including MVPA min · hr−1, ST min · hr−1, and breaks · hr−1 explained 41.5% of LEF variance. Each additional break · hr−1 was associated with 0.58 point increase in LEF. Breaks and MVPA had strongest independent associations with LEF. Promoting regular breaks might be useful in maintaining or increasing LEF and later life independence. This novel finding is important for the design of effective lifestyle interventions targeting older adults.

Abstract Background Early-life stress (ES) is an emerging risk factor for later-life development of Alzheimer’s disease (AD). We have previously shown that ES modulates amyloid-beta pathology and the microglial response to it in the APPswe/PS1dE9 mouse model. Because astrocytes are key players in the pathogenesis of AD, we studied here if and how ES affects astrocytes in wildtype (WT) and APP/PS1 mice, and how these relate to the previously reported amyloid pathology and microglial profile. Methods We induced ES by limiting nesting and bedding material from postnatal days (P) 2-9. We studied in WT mice (at P9, P30 and 6 months) and in APP/PS1 mice (at 4 and 10 months) i) GFAP coverage, cell density and complexity in hippocampus (HPC) and entorhinal cortex (EC); ii) hippocampal gene expression of astrocyte markers; and iii) the relationship between astrocyte, microglia and amyloid markers. Results In WT mice, ES increased GFAP coverage in HPC subregions at P9, and decreased it at 10 months. APP/PS1 mice at 10 months exhibited both individual cell as well as clustered GFAP signals. APP/PS1 mice when compared to WT exhibited reduced total GFAP coverage in HPC, which is increased in the EC, while coverage of the clustered GFAP signal in the HPC was increased and accompanied by increased expression of several astrocytic genes. While measured astrocytic parameters in APP/PS1 mice appear not be further modulated by ES, analyzing these in the context of ES-induced alterations to amyloid pathology and microglial shows alterations at both 4 and 10 months of age. Conclusions Our data suggest that ES leads to alterations to the astrocytic response to amyloid-β pathology.
