Background Multiple myeloma is a haematological blood cancer of the bone marrow and is classified by the World Health Organisation (WHO) as a plasma cell neoplasm. In multiple myeloma, normal plasma cells transform into malignant myeloma cells and produce large quantities of an abnormal immunoglobulin called monoclonal protein or M protein. This ultimately causes multiple myeloma symptoms such as bone damage or kidney problems. The annual worldwide incidence of multiple myeloma is estimated to be 6 - 7/100,000 and accounts for 1% of all cancer...

Xusheng Qian, He Huang, Xiaoping Chen, Tingwen Huang
This paper investigates the construction of sparse radial basis function neural networks (RBFNNs) for classification problems. An efficient two-phase construction algorithm (which is abbreviated as TPCLR1 for simplicity) is proposed by using L1 regularization. In the first phase, an improved maximum data coverage (IMDC) algorithm is presented for the initialization of RBF centers and widths. Then a specialized Orthant-Wise Limited-memory Quasi-Newton (sOWL-QN) method is employed to perform simultaneous network pruning and parameter optimization in the second phase...

The cranial defects are complex in nature and are due to various causes. Therefore, there is a need for a common term of reference to these defects. This requirement stood as a prime reason for proposing a classification system for cranial defects. The classification is based on 2 decades of experience in cranioplasty. This efficient and simple way of representation would fill the existing lacunae for a systematic communication on cranial defects. Over the ages the evolution of reconstruction and grafting had undergone a massive progress...

BACKGROUND: Duchenne muscular dystrophy (DMD) is the most frequent inherited form of muscular dystrophy during childhood. DMD is a severe and progressive disease. Children initially have no symptoms, but the diagnosis is often delayed until the child is about 5 years old. PURPOSE: Although few studies have addressed parent reactions to DMD, parental reactions to other serious childhood conditions have been documented. This study aims to understand the resolution styles that parents use in the context of their children with DMD...

Mitogen-activated protein kinase (MAPK) cascades are highly conserved signaling modules in eukaryotes, including yeasts, plants and animals. MAPK cascades are responsible for protein phosphorylation during signal transduction events, and typically consist of three protein kinases: MAPK, MAPK kinase, and MAPK kinase kinase. In this current study, we identified a total of 12 FvMAPK, 7 FvMAPKK, 73 FvMAPKKK, and one FvMAPKKKK genes in the recently published Fragaria vesca genome sequence. This work reported the classification, annotation and phylogenetic evaluation of these genes and an assessment of conserved motifs and the expression profiling of members of the gene family were also analyzed here...

BACKGROUND: The concepts of impulsivity and compulsivity are commonly used in psychiatry. Little is known about whether different manifest measures of impulsivity and compulsivity (behavior, personality, and cognition) map onto underlying latent traits; and if so, their inter-relationship. METHODS: A total of 576 adults were recruited using media advertisements. Psychopathological, personality, and cognitive measures of impulsivity and compulsivity were completed...

OBJECTIVE: To examine whether high-frequency (10 Hz) repetitive transcranial magnetic stimulation (rTMS), applied over the primary motor cortex of the affected hemisphere, could be used to manage hemiplegic shoulder pain (HSP). METHODS: Twenty-four chronic stroke patients with chronic HSP, randomly assigned into the rTMS group (10 sessions of high-frequency stimulation) or the sham group (sham stimulation), was performed. The Numeric Rating Scale (NRS) was used to evaluate the intensity of pain at pre-treatment, and at one day, and one, two, and four weeks after treatment...

Astrocytes, a subtype of glial cells, come in variety of forms and functions. However, overarching role of these cell is in the homeostasis of the brain, be that regulation of ions, neurotransmitters, metabolism or neuronal synaptic networks. Loss of homeostasis represents the underlying cause of all brain disorders. Thus, astrocytes are likely involved in most if not all of the brain pathologies. We tabulate astroglial homeostatic functions along with pathological condition that arise from dysfunction of these glial cells...

Motor-imagery tasks are a popular input method for controlling brain-computer interfaces (BCIs), partially due to their similarities to naturally produced motor signals. The use of functional near-infrared spectroscopy (fNIRS) in BCIs is still emerging and has shown potential as a supplement or replacement for electroencephalography. However, studies often use only two or three motor-imagery tasks, limiting the number of available commands. In this work, we present the results of the first four-class motor-imagery-based online fNIRS-BCI for robot control...

Macrophages are an essential component of innate immunity and play a vital role in inflammation and host defense. Based on immunological responses, the macrophages are classified into "activated" macrophage (M1 macrophages) participating in the responses of type I helper T (Th1) cells to pathogens and "alternatively activated" macrophages (M2 macrophages) in response to interleukin (IL)-4 and IL-13. In this review, we discuss the origin, classification and function of macrophages. We also discuss the mechanisms underlying polarization of different macrophage subtypes, including transcriptional, epigenetic and post-transcriptional regulation...

Soluble CD40 ligand (sCD40L) has been implicated in the development of renal injury. The CD40 receptor exists in a soluble form, sCD40R, and has been shown to function as a competitive antagonist against CD40 activation. We analyzed whether plasma levels of sCD40L and sCD40R predict changes in renal function in an all-cause chronic kidney disease (CKD) cohort. Stratification of subjects based on sCD40L and sCD40R individually, as well as in combination, demonstrated that sCD40L was directly associated with declines in estimated glomerular filtration rate (eGFR)...

REVIEW
João Loula, Gaël Varoquaux, Bertrand Thirion
Most current functional Magnetic Resonance Imaging (fMRI) decoding analyses rely on statistical summaries of the data resulting from a deconvolution approach: each stimulation event is associated with a brain response. This standard approach leads to simple learning procedures, yet it is ill-suited for decoding events with short inter-stimulus intervals. In order to overcome this issue, we propose a novel framework that separates the spatial and temporal components of the prediction by decoding the fMRI time-series continuously, i...

Intramuscular fat (IMF) content and fatty acid composition of longissimus dorsi muscle (LM) change with growth, which partially determines the flavor and nutritional value of goat (Capra hircus) meat. However, unlike cattle, little information is available on the transcriptome-wide changes during different postnatal stages in small ruminants, especially goats. In this study, the sequencing reads of goat LM tissues collected from kid, youth, and adult period were mapped to the goat genome. Results showed that out of total 24 689 Unigenes, 20 435 Unigenes were annotated...

Fotios Alexandros Karakostis, Carlos Lorenzo, Konstantinos Moraitis
In previous studies, the anatomy of proximal hand phalanges has been described and techniques of anatomical allocation have been developed. However, these rely on the observation of small phalangeal traits without providing a multivariate analysis of morphological variation. In bioarchaeological contexts, the form of these distinctive traits is often not clear and the use of alternative supplementary methods is vital. This study aims to conduct a multivariate analysis of proximal phalanges and introduce a new methodology of ray allocation for isolated proximal phalanges...

There is increasing research interest in technologies that can detect grasping, to encourage functional use of the hand as part of daily living, and thus promote upper-extremity motor recovery in individuals with stroke. Force myography (FMG) has been shown to be effective for providing biofeedback to improve fine motor function in structured rehabilitation settings, involving isolated repetitions of a single grasp type, elicited at a predictable time, without upper-extremity movements. The use of FMG, with machine learning techniques, to detect and distinguish between grasping and no grasping, continues to be an active area of research, in healthy individuals...

An accurate measure of mental workload level has diverse neuroergonomic applications ranging from brain computer interfacing to improving the efficiency of human operators. In this study, we integrated electroencephalogram (EEG), functional near-infrared spectroscopy (fNIRS), and physiological measures for the classification of three workload levels in an n-back working memory task. A significantly better than chance level classification was achieved by EEG-alone, fNIRS-alone, physiological alone, and EEG+fNIRS based approaches...
