Because abortion is legal only to save a womans life most procedures are clandestine and many are carried out in unsafe circumstances. Unsafe abortion can endanger womens reproductive health and lead to serious often life-threatening complications. Furthermore unsafe abortions impose a heavy burden on women their families and society by virtue of the serious health consequences that often ensue: These health problems can keep women from work and school and treatment can be costly and consume scarce medical resources at both public and private health institutions. Because abortion is highly stigmatized and largely prohibited information on abortion is difficult to obtain. However new research findings shed light on the causes level and consequences of abortion in the Philippines. (excerpt)

These neurocognitive impairments such as memory, attention, and executive functions appear to be associated with dysfunction in brain regions. This study was conducted to investigate the metabolic changes in the brain subcortical regions, i.e., posterior parietal cortex and dorsolateral prefrontal cortex (DLPFC), in patients with hyperthyroidism before and after antithyroid treatment using proton magnetic resonance spectroscopy (1H MRS).Materials and Methods: We collected neuropsychological and 1H MRS data from posterior parietal cortex and DLPFC, in both control (N = 30) and hyperthyroid (N = 30) patients. In addition, follow-up data were available for 19 patients treated with carbimazole for 30 weeks. The relative ratios of the neurometabolites were calculated using the Linear Combination Model ...

In the molecular structure of the studied complex, Cd(II) ion is six-coordinated, which is completed by two water molecules and two 2-PTZ ligands which provide two nitrogens from the two tetrazolyl groups and two nitrogen atoms from pyridyl rings. The mononuclear units are assembled by intermolecular hydrogen bonding to generate two-dimensional sheets. Photoluminescence spectrum of the polymer complex exhibits strong blue emission at λ max = 439 nm in the solid state at room temperature.

Regulatory ncRNAs, ranging from small to long ncRNAs (lncRNAs), exert their control over a vast array of biological processes. Based on the mode of biogenesis and their function, ncRNAs evolved into different forms that include microRNAs (miRNAs), small interfering RNAs (siRNAs), miRNA variants (isomiRs), lncRNAs, circular RNAs (circRNAs), and derived ncRNAs. This article explains the different classes of ncRNAs and their role in plant development and stress responses. Furthermore, the applications of regulatory ncRNAs in crop improvement, targeting agriculturally important traits, have been discussed.

Mammillary bodies are key brain sites that regulate memory; however, their integrity in SVHD is unclear. We evaluated mammillary body (MB) volumes and their associations with cognitive/memory scores in SVHD and controls. METHODS: Brain MRI data were collected from 63 adolescents (25 SVHD; 38 controls) using a 3.0-Tesla MRI scanner. Cognition and memory were assessed using Montreal Cognitive Assessment (MoCA) and Wide Range Assessment of Memory and Learning 2. MB volumes were calculated and compared between groups (ANCOVA, covariates: age, sex, and total brain volume [TBV]). Partial correlations and linear regression were performed to examine associations between volumes and cognitive scores (covariates: age, sex, and TBV). RESULTS: SVHD group showed significantly lower MoCA and WRAML2 scores over controls. MB volumes were significantly reduced in SVHD over controls. After controlling for age, sex, and TBV, MB volumes correlated with MoCA and delayed memory recall scores in SVHD and controls. CONCLUSION: Adolescents with SVHD show reduced MB volumes associated with cognitive/memory deficits. Potential mechanisms of volume losses may include developmental and/or hypoxic/ischemic-induced processes. Providers should screen for cognitive deficits and explore possible interventions to improve memory.

The hippocampus is a brain structure that is significantly involved in memory and mood function and shows impairment in schizophrenia. In the present study, we examined the regional hippocampal changes in schizophrenia patients using voxel-based morphometry (VBM), Freesurfer, and proton magnetic resonance spectroscopy (1H MRS) procedures. 1H MRS and high-resolution T1-weighted magnetic resonance imaging were collected in both healthy control subjects (N = 28) and schizophrenia patients (N = 28) using 3-Tesla whole body MRI system. Regional hippocampal volume was analyzed using VBM and Freesufer procedures. The relative ratios of the neurometabolites were calculated using linear combination model (LCModel). Compared to controls, schizophrenia patients showed significantly decreased gray matter volume in the hippocampus. Schizophrenia patients also ...

However, the gray matter integrity in autonomic, mood, and cognitive control sites is unclear. We examined regional brain gray matter changes, using high-resolution T1-weighted images (3.0-T magnetic resonance scanner) with voxel based morphometry procedures, as well as mood and cognitive functions in SVHD (n=18; age, 15.7±1.1years; male, 10) and controls (n=31; age, 16.0±1.1years; male, 17). High-resolution T1-weighted images were realigned, gray matter tissue type partitioned, normalized to a common space, smoothed, and compared between groups (analysis of covariance; covariates, age and gender). The mood and cognitive scores were compared between groups using independent samples t-tests. SVHD subjects showed significantly altered mood and cognitive functions over controls. Significantly reduced gray matter emerge...

The selected subjects were divided into four groups viz., group I, II, III and IV having thirty subjects each. The subjects of group I were not given any treatment. The nutrition education was given for three months after fifteen days interval to the subjects of group II, III and IV through individual and group contact and gain in nutrition knowledge was assessed after the study. The mean daily intake of green leafy vegetables, other vegetables and fruits increased significantly (P=0.01) in the subjects of group II, III and IV and a non-significant increase (P=0.01) was seen in the subjects of group I. The mean energy, carbohydrates, protein and fat intake decreased significantly (P=0.01) in the subjects of group II, III and IV and a non-significant decrease (P=0.01) was seen in the subjects of group I. Therefore, it can be reported from the results that supplementation of bael (Aegle marmelos L.) leaf, pulp and seed powder along with nutrition counseling significantly improved the food and nutrient inake of the diabetic patients.

However, prior to its industrial use, a lot of crop improvement efforts are required in Jatropha. Availability of a large number of EST sequences of Jatropha in public domain allow identification of candidate genes for several agronomic characters including oil content in seeds. Here, we have analysed 42,477 ESTs of Jatropha spanning 22.9 Mbp for microsatellites and fatty acid metabolism related sequences. Unigene sequences were built using CAP 3 programme resulted in 12,358 contigs and 5,730 singlets. Nearly, 8 % unigenes showed presence of microsatellites, slightly overrepresented compared to their occurrence in ESTs. Most of the microsatellites were either di-or tri-nucleotide repeats, while other categories of tetra-, penta-and hexa-nucleotide repeats together constituted~4 % of total microsatellites. Assessment of functional relevance of unigenes was carried out using Blast2GO using its default settings. The overall sequence similarity level against sequences in 'nr' database was >80 %. A total of 931 sequences that participated in any of the pathways related to fatty acid or lipid metabolism were found at GO level 6. Among these, GO terms "Fatty acid metabolic process" and "Fatty acid biosynthetic process" were most overrepresented. Overall, our work has due relevance in identifying molecular markers for the candidate genes for oil content in Jatropha seeds, and will prove to be an important reference for further studies for identification of trait specific markers in Jatropha.

Pharmacognostical study counting both macroscopic and powder microscopy of raw drug exposed the quality and genuineness of all the constituents of VAK. Organoleptic features of coarse powder made out of the crude drugs were within the standard range. Specific gravity of the decoction was 1.0185 and pH was 5.5.Total solid content present in the Kwatha was 4.525% w/v, total ash 0.949% w/v, and acid insoluble ash was 0.052% w/v. Iron assay showed the presence of Fe 2 O 3 as 0.065% w/v. Qualitative scrutiny demonstrated the presence of flavonoids and tannis. Thin Layer Chromatography (TLC) and High Performance Thin Layer Chromatography (HPTLC) were carried out after organizing appropriate solvent system in which maximum three spots were distinguished in TLC and nine spots in HPTLC and most of the R f values were identical when done with different sample extractive methods. This shows the presence of certain definite constituents in the decoction and is helpful for the easy separation of these constituents.
