This study tested for association between Toxoplasma gondii and pregnancy and abortion to investigate sub-optimal reproduction in farmed red deer (Cervus elaphus). Sera from a sub-sample (n = 2304) of pregnant and non-pregnant hinds in early gestation at first pregnancy scan (scan 1) and approximately at the end of second trimester at second pregnancy scan (scan 2) were tested for T. gondii antibodies using a validated ELISA.

The inhibitor NU 2058 [6-(cyclohexylmethoxy)-9-purin-2-amine] leads to G1-phase cell cycle arrest in the marine diatom, by binding to two cyclin-dependent kinases, CDKA1 and CDKA2. NU 2058 has no effect on photosynthetic attributes, such as F/F, chlorophyll /cell, levels of D2 PSII subunits, or RbcL; however, cell cycle arrest leads to unbalanced growth whereby photosynthetic products that can no longer be used for cell division are redirected toward carbohydrates and triacylglycerols (TAGs). Arrested cells up-regulate most genes involved in fatty acid synthesis, including acetyl-CoA carboxylase, and three out of five putative type II diglyceride acyltransferases (DGATs), the enzymes that catalyze TAG production.

Between 2009 and 2012, two kereru (Hemiphaga novaeseelandiae), one North Island brown kiwi (Apteryx mantelli), and one North Island kaka (Nestor meridionalis) were submitted for necropsy examination. On gross postmortem, the kiwi had marked hepatosplenomegaly while the kaka and two kereru had swollen, slightly firm, deep-red lungs.

A treatment in which tungstate was supplemented to cells grown with ammonium was also included. In nutrient replete conditions, cells grew exponentially and possessed virtually identical 1/ϕμ of 40-44 mol photons · mol C(-1) .

Methods: An enrichment method was used to isolate Arcobacter spp from diarrhoeal human faeces submitted to a community laboratory in Hawke's Bay. The identity of isolates was confirmed by PCR and their diversity was determined by pulsed field gel electrophoresis (PFGE).

Soil warming has the potential to alter both soil and plant processes that affect carbon storage in forest ecosystems. We have quantified these effects in a large, long-term (7-y) soil-warming study in a deciduous forest in New England. Soil warming has resulted in carbon losses from the soil and stimulated carbon gains in the woody tissue of trees.

In order to optimize 24-h H(2) production this study used Response Surface Methodology and Q2, an optimization algorithm, to investigate the effects of five inhibitors of the photosynthetic and respiratory electron transport chains of Synechocystis sp. PCC 6803.

Objective: To explore the effects of GengNianLe (GNL, also called perimenopausal depression relieving formula), a defined formula of Chinese medicinal herbs in relieving perimenopausal depression in Chinese women.
Methods: Between September 2004 and April 2008, 47 Chinese women were randomized into a GNL group (n = 21) and a control group which received tibolone (n = 26) using a randomization chart. Depression was rated with the 24-item Hamilton Depression Scale (HAMD).
The nitrogen (N) concentration and pH of culture media were optimized for increased fermentative hydrogen (H(2)) production from the cyanobacterium, Synechocystis sp. PCC 6803. The optimization was conducted using two procedures, response surface methodology (RSM), which is commonly used, and a memory-based machine learning algorithm, Q2, which has not been used previously in biotechnology applications.

Twenty male Sprague-Dawley (SD) rats were divided randomly into two groups. Group A was treated with a combination of oral administration of Scutellaria baicalensis Georgi extracts and acupuncture.

We present the case of a young woman who suffered from right cervical lymphadenopathy with associated malaise for 8 weeks. The sonography showed multiple, enlarged lymph nodes in the cervical, submaxillary, and subclavicular chains on the right side. The biopsy of a right cervical lymph node disclosed necrosis, histiocytic accumulation, infiltration with lymphocytes and immunoblasts, and cellular debris, demonstrating histiocytic necrotizing lymphadenitis (HNL).

After treatment, the plasma concentration of baicalin was determined using high performance liquid chromatography (HPLC), the serum levels of tumor necrosis factor-alpha (TNF-alpha) and Interleukin 6 (IL-6) were detected with enzyme-linked immunosorbent assay (ELISA).

This paper describes a screening assay, compatible with high-throughput bioprospecting or molecular biology methods, for assessing biological hydrogen (H2) production. While the assay is adaptable to various physical configurations, we describe its use in a 96-well, microtiter plate format with a lower plate containing H2-producing cyanobacteria strains and controls and an upper, membrane-bottom plate containing a color indicator and a catalyst. H2 produced by cells in the lower plate diffuses through the membrane into the upper plate, causing a color change that can be quantified with a microplate reader.

Objectives: To conduct a systematic review of the evidence for the effectiveness of five visual electrodiagnostic tests to inform the Medical Services Advisory Committee (MSAC) of the Department of Health and Ageing (Australia) in its decision in allocating public funding for new technologies.
Methods: We searched the biomedical literature to identify English-language articles published from 1966 to September 2000. We assessed validity of methodology of included studies against the following criteria: investigators (i) compared test with an appropriate reference test; (ii) tested an appropriate spectrum of patients; (iii) masked assessment of study and reference tests; (iv) measured the study test independently of clinical information; and (v) measured the reference test before any interventions.
Background: We have previously shown that parents of premature children provided relatively high valuation of their children's health state in adolescence. However, stability of parental preferences for future pediatric health states is unknown during the antenatal and neonatal periods and infancy.
Objective: To determine whether preference-based, health-related quality-of-life scores obtained serially from 2 cohorts (women with high-risk pregnancies [antenatal cohort] and mothers of very low-birth-weight newborns [VLBW cohort]) are stable during the first year after birth.
BACKGROUND: Uncertainty remains about the potential harmful effects of antihypertensive therapy on the developing fetus, especially for beta-blockers (betab). METHODS: We prospectively enrolled all singleton women with a blood pressure >/= 140/90 mm Hg during pregnancy. The main analysis included 1948 women with all forms of hypertension and compared the use of betab drugs, non-betab drugs or a combination of both, to no treatment.
