Maximizing cohesion and separation for detecting protein functional modules in protein-protein interaction networks.

PLoS One 2020 13;15(10):e0240628. Epub 2020 Oct 13.

Department of Information Management, Chang Gung University, Taoyuan, Taiwan.

Protein Function Module (PFM) identification in Protein-Protein Interaction Networks (PPINs) is one of the most important and challenging tasks in computational biology. The quick and accurate detection of PFMs in PPINs can contribute greatly to the understanding of the functions, properties, and biological mechanisms in research on various diseases and the development of new medicines. Despite the performance of existing detection approaches being improved to some extent, there are still opportunities for further enhancements in the efficiency, accuracy, and robustness of such detection methods.

Technical Note: On the accuracy of parametric two-parameter photon cross-section models in dual-energy CT applications.

Med Phys 2017 Jun 25;44(6):2438-2446. Epub 2017 Apr 25.

Medical Physics Graduate Program, Department of Radiation Oncology, Virginia Commonwealth University, Richmond, VA, 23298, USA.

Purpose: To evaluate and compare the theoretically achievable accuracy of two families of two-parameter photon cross-section models: basis vector model (BVM) and modified parametric fit model (mPFM).

Method: The modified PFM assumes that photoelectric absorption and scattering cross-sections can be accurately represented by power functions in effective atomic number and/or energy plus the Klein-Nishina cross-section, along with empirical corrections that enforce exact prediction of elemental cross-sections. Two mPFM variants were investigated: the widely used Torikoshi model (tPFM) and a more complex "VCU" variant (vPFM). Read More

Electronic address:

Androgen deprivation in males has detrimental effects on various tissues and bodily functions, some of which can be restored by estradiol (E2) administration. We investigated how the duration of androgen deprivation affects the autoregulation of estrogen receptors (ERs) levels in core brain areas associated with sexual behavior and cognition, as well as in pelvic floor muscles (PFM). We also measured c-Fos levels in brain areas associated with sexual behavior shortly after the rats mated. Read More

Dissociations between spatial-attentional processes within parietal cortex: insights from hybrid spatial cueing and change detection paradigms.

Front Hum Neurosci 2013 16;7:366. Epub 2013 Jul 16.

Laboratory for Cognitive Neurology, Department of Neurosciences, Katholieke Universiteit Leuven Leuven, Belgium ; Neurology Department, University Hospitals Leuven Leuven, Belgium.

Spatial cueing has been used by many different groups under multiple forms to study spatial attention processes. We will present evidence obtained in brain-damaged patients and healthy volunteers using a variant of this paradigm, the hybrid spatial cueing paradigm, which, besides single-target trials with valid and invalid cues, also contains trials where a target is accompanied by a contralateral competing stimulus (competition trials). This allows one to study invalidity-related processes and selection between competing stimuli within the same paradigm. Read More

Multiple components are integrated to determine leaf complexity in Lotus japonicus.

J Integr Plant Biol 2013 May;55(5):419-33

National Key Laboratory of Plant Molecular Genetics, Institute of Plant Physiology and Ecology, Shanghai Institutes for Biological Sciences, Graduate School of the Chinese Academy of Sciences, the Chinese Academy of Sciences, Shanghai 20032, China.

Transcription factors and phytohormones have been reported to play crucial roles to regulate leaf complexity among plant species. Using the compound-leafed species Lotus japonicus, a model legume plant with five visible leaflets, we characterized four independent mutants with reduced leaf complexity, proliferating floral meristem (pfm), proliferating floral organ-2 (pfo-2), fused leaflets1 (ful1) and umbrella leaflets (uml), which were further identified as loss-of-function mutants of Arabidopsis orthologs LEAFY (LFY), UNUSUAL FLORAL ORGANS (UFO), CUP-SHAPED COTYLEDON 2 (CUC2) and PIN-FORMED 1 (PIN1), respectively. Comparing the leaf development of wild-type and mutants by a scanning electron microscopy approach, leaflet initiation and/or dissection were found to be affected in these mutants. Read More

Effect of a probiotic fermented milk on the thymus in Balb/c mice under non-severe protein-energy malnutrition.

Br J Nutr 2013 Aug 3;110(3):500-8. Epub 2013 Jan 3.

Centro de Referencia para Lactobacilos (CERELA-CONICET), Chacabuco 145, San Miguel de Tucumán (T4000ILC) Tucumán, Argentina.

Protein–energy malnutrition (PEM) causes a significant impairment of the immune system, the thymus being one of the most affected organs. It has been demonstrated that the administration of probiotic fermented milk (PFM) recovered the intestinal barrier, histological alterations and mucosal and systemic immune functions in a non-severe malnutrition model using BALB/c mice. The aim of the present study was to evaluate, in the same model of malnutrition, the effect of a PFM added to a re-nutrition diet on the recovery of the thymus, analysing histological and functional alterations caused by malnutrition.

Biofeedback and the electromyographic activity of pelvic floor muscles in pregnant women.

Rev Bras Fisioter 2011 Sep-Oct;15(5):386-92. Epub 2011 Oct 14.

Faculty of Medicine of Ribeirão Preto (FMRP), Universidade de São Paulo (USP), Ribeirão Preto, SP, Brazil.

Background: Maintaining continence is among the functions of the pelvic floor muscles (PFM) and their dysfunction can cause urinary incontinence (UI), which is a common occurrence during pregnancy and the puerperal period. Pelvic floor muscle training (PFMT), therefore, is important during pregnancy, although most women perform the muscle contractions unsatisfactorily.
