Do Alternative Therapies Have a Role in Autism?
Interventions considered to be branches of Complementary & Alternative Medicine (CAM) for autism are on the rise. Many new treatments have emerged & traditional beliefs of Ayurveda, Yoga, Behavioral therapy, Speech therapy and Homoeopathy have gained popularity and advocacy among parents. It is imperative that data supporting new treatments should be scrutinized for scientific study design, clinical safety, and scientific validity, before embarking on them as modes of therapy. Practitioners take care in explaining the rationale behind the various approaches that they practice, it is important to indicate possible limitations too during the initial clinical examination and interactive session. Clinicians must remember that parents may have different beliefs regarding the effectiveness of treatment since their information is derived more from the ‘hear-say’ route when they compare benefits/effects of CAM therapies on other children and often underestimate differential tolerance for treatment risks. It is thus significant that practitioners do not assume a "don't ask, don't tell" posture. The scientific validation and support for many interventions is incomplete and very different from the recommendations of the American Academy of Pediatrics Policy Statement. In this article, we discuss the various modes of CAM and their utilities and limitations in relation to autism
Assessment of Metabolic Parameters For Autism Spectrum Disorders
Autism is a brain development disorder that first appears during infancy or childhood, and generally follows a steady course without remission. Impairments result from maturation-related changes in various systems of the brain. Autism is one of the five pervasive developmental disorders (PDD), which are characterized by widespread abnormalities of social interactions and communication, and severely restricted interests and highly repetitive behavior. The reported incidence of autism spectrum disorders (ASDs) has increased markedly over the past decade. The Centre for Disease Control and Prevention has recently estimated the prevalence of ASDs in the United States at approximately 5.6 per 1000 (1 of 155 to 1 of 160) children. Several metabolic defects, such as phenylketonuria, are associated with autistic symptoms. In deciding upon the appropriate evaluation scheme a clinician must consider a host of different factors. The guidelines in this article have been developed to assist the clinician in the consideration of these factors
Polymorphism identification and improved genome annotation of Brassica rapa through Deep RNA sequencing.
The mapping and functional analysis of quantitative traits in Brassica rapa can be greatly improved with the availability of physically positioned, gene-based genetic markers and accurate genome annotation. In this study, deep transcriptome RNA sequencing (RNA-Seq) of Brassica rapa was undertaken with two objectives: SNP detection and improved transcriptome annotation. We performed SNP detection on two varieties that are parents of a mapping population to aid in development of a marker system for this population and subsequent development of high-resolution genetic map. An improved Brassica rapa transcriptome was constructed to detect novel transcripts and to improve the current genome annotation. This is useful for accurate mRNA abundance and detection of expression QTL (eQTLs) in mapping populations. Deep RNA-Seq of two Brassica rapa genotypes-R500 (var. trilocularis, Yellow Sarson) and IMB211 (a rapid cycling variety)-using eight different tissues (root, internode, leaf, petiole, apical meristem, floral meristem, silique, and seedling) grown across three different environments (growth chamber, greenhouse and field) and under two different treatments (simulated sun and simulated shade) generated 2.3 billion high-quality Illumina reads. A total of 330,995 SNPs were identified in transcribed regions between the two genotypes with an average frequency of one SNP in every 200 bases. The deep RNA-Seq reassembled Brassica rapa transcriptome identified 44,239 protein-coding genes. Compared with current gene models of B. rapa, we detected 3537 novel transcripts, 23,754 gene models had structural modifications, and 3655 annotated proteins changed. Gaps in the current genome assembly of B. rapa are highlighted by our identification of 780 unmapped transcripts. All the SNPs, annotations, and predicted transcripts can be viewed at http://phytonetworks.ucdavis.edu/
Eigenvalue hypothesis for multi-strand braids
Computing polynomial form of the colored HOMFLY-PT for non-arborescent knots
obtained from three or more strand braids is still an open problem. One of the
efficient methods suggested for the three-strand braids relies on the
eigenvalue hypothesis which uses the Yang-Baxter equation to express the answer
through the eigenvalues of the -matrix. In this paper, we generalize
the hypothesis to higher number of strands in the braid where commuting
relations of non-neighbouring matrices are also incorporated. By
solving these equations, we determine the explicit form for
-matrices and the inclusive Racah matrices in terms of braiding
eigenvalues (for matrices of size up to 6 by 6). For comparison, we briefly
discuss the highest weight method for four-strand braids carrying fundamental
and symmetric rank two representation. Specifically, we present all
the inclusive Racah matrices for representation and compare with the
matrices obtained from eigenvalue hypothesis.Comment: 23 page
In vivo and In vitro Interactions between Pseudomonas aeruginosa and Staphylococcus spp.
The significance of polymicrobial infections is increasingly being recognized especially in a biofilm context wherein multiple bacterial species—including both potential pathogens and members of the commensal flora—communicate, cooperate, and compete with each other. Two important bacterial pathogens that have developed a complex network of evasion, counter-inhibition, and subjugation in their battle for space and nutrients are Pseudomonas aeruginosa and Staphylococcus aureus. Their strain- and environment-specific interactions, for instance in the cystic fibrosis lung or in wound infections, show severe competition that is generally linked to worse patient outcomes. For instance, the extracellular factors secreted by P. aeruginosa have been shown to subjugate S. aureus to persist as small colony variants (SCVs). On the other hand, data also exist where S. aureus inhibits biofilm formation by P. aeruginosa but also protects the pathogen by inhibiting its phagocytosis. Interestingly, such interspecies interactions differ between the planktonic and biofilm phenotype, with the extracellular matrix components of the latter likely being a key, and largely underexplored, influence. This review attempts to understand the complex relationship between P. aeruginosa and Staphylococcus spp., focusing on S. aureus, that not only is interesting from the bacterial evolution point of view, but also has important consequences for our understanding of the disease pathogenesis for better patient management
Controlled-Joint Remote Implementation of Operators and its Possible Generalization
The existing notion of the shared entangled state-assisted remote preparation
of unitary operator (equivalently the existing notion of quantum remote
control) using local operation and classical communication is generalized to a
scenario where under the control of a supervisor two users can jointly
implement arbitrary unitaries (one unknown unitary operation by each or
equivalently a single unitary decomposed into two unitaries of the same
dimension and given to two users) on an unknown quantum state available with a
geographically separated user. It is explicitly shown that the task can be
performed using a four-qubit hyperentangled state, which is entangled
simultaneously in both spatial and polarization degrees of freedom of photons.
The proposed protocol which can be viewed as primitive for distributed photonic
quantum computing is further generalized to the case that drops the
restrictions on the number of controllers and the number of parties performing
unitaries and allows both the numbers to be arbitrary. It is also shown that
all the existing variants of quantum remote control schemes can be obtained as
special cases of the present scheme.Comment: 12 pages, 4 figure
