• ### English K-6 Modules

Teaching language as an activity is important especially where learners lack the expected writing proficiency. In Andhra Pradesh, it has been observed that many ESL learners at class IX level, especially those from regional medium schools do not have the required writing proficiency. This could be because of several factors such as inadequate writing practice in the classroom, poor vocabulary, examination oriented writing, teacher- dictated writing, lack of exposure to English, lack of a homogenous English speaking community, limited reading habits and so on.

• ### Threadneedle Investment Funds IV ICVC – Retail Class

One of the most fundamental Dodd-Frank changes affecting private funds is the elimination of the “private advisers” exemption from registration with the SEC as an investment adviser (also known as the “15-client” exemp- tion). In its place, Dodd-Frank created several new, but less comprehensive, exemptions, with the result that most U.S.

• ### Báo cáo khoa học: Ligand binding and antigenic properties of a human neonatal Fc receptor with mutation of two unpaired cysteine residues

The neonatal Fc receptor (FcRn) is a major histocompatibility complex class I-related molecule that regulates the half-life of IgG and albumin. In addition, FcRn directs the transport of IgG across both mucosal epithe-lium and placenta and also enhances phagocytosis in neutrophils. This new knowledge gives incentives for the design of IgG and albumin-based diag-nostics and therapeutics.

• ### Báo cáo khóa học: The zinc-binding site of a class I aminoacyl-tRNA synthetase is a SWIM domain that modulates amino acid binding via the tRNA acceptor arm

In its tRNA acceptor end binding domain, the glutamyl-tRNA synthetase (GluRS) of Escherichia colicontains one atom ofzinc that holds the extremities ofa segment (Cys98-x-Cys100-x24-Cys125-x-His127) homologous to the Escherichia coliglutaminyl-tRNA synthetase (GlnRS) loop where a leucine residue stabilizes the peeled-back conformation of tRNA Gln acceptor end. We report here that the GluRS zinc-binding region belongs to the novel SWIM domain family characterized by the signature C-x-C-xn-C-x-H (n¼6–25),...

• ### Báo cáo khoa học: Phaiodotoxin, a novel structural class of insect-toxin isolated from the venom of the Mexican scorpion Anuroctonus phaiodactylus

Apeptide called phaiodotoxin was isolated from the venom of the scorpionAnuroctonus phaiodactylus.It is lethal to crickets, but non toxic tomice at the doses assayed. It has 72 amino acid residues, with a molecular mass of 7971 atomic mass units. Its covalent structure was determined by Edman degradation and mass spectrometry; it contains four disul-fide-bridges, of which one of the pairs is formed between cysteine-7 and cysteine-8 (positions Cys63–Cys71). The other three pairs are formed between Cys13–Cys38, Cys23– Cys50 and Cys27–Cys52. ...

• ### Báo cáo khoa học: The antibiotic activity of cationic linear amphipathic peptides: lessons from the action of leucine/lysine copolymers on bacteria of the class Mollicutes

Peptides composed of leucyl and lysyl residues (LK pep-tides) with different compositions and sequences were compared for their antibacterial activities usingcell wall-less bacteria of the classMollicutes(acholeplasmas, mycoplas-mas and spiroplasmas) as targets. The antibacterial activity of the amphipathica-helical peptides varied with their size, 15 residues beingthe optimal length, independent of the membrane hydrophobic core thickness and the amount of cholesterol.

• ### MOLECULAR MECHANISMS OF CANCER

Cancer may constitute the most extensively studied disease entity of our time. Nevertheless, our comprehension of the cellular and molecular pathology of malignant transformation is incomplete. In view of the diverse clinical presentations of various malignancies, doubts may be raised as to whether it is appropriate to refer to cancer as one group of disease states. The notion of malignant tumors as a pathologic and pathophysiologic class of conditions begs the question for defining criteria that characterize all malignant growths, regardless of their tissue of origin....

• ### Đề tài " A C1-generic dichotomy for diffeomorphisms: Weak forms of hyperbolicity or infinitely many sinks or sources "

A C 1-generic dichotomy for diﬀeomorphisms: Weak forms of hyperbolicity or inﬁnitely many sinks or sources By C. Bonatti, L. J. D´ ıaz, and E. R. Pujals* A Ricardo Ma˜e (1948–1995), por todo su trabajo n´ Abstract We show that, for every compact n-dimensional manifold, n ≥ 1, there is a residual subset of Diﬀ1 (M ) of diﬀeomorphisms for which the homoclinic class of any periodic saddle of f veriﬁes one of the following two possibilities: Either it is contained in the closure of an inﬁnite set of sinks or sources (Newhouse phenomenon), or it presents some weak form of...

(After Ref. 74.) 2 structures, including pressurized cabins and pressure vessels, relatively large amounts of damage may be contained by providing tear straps or stiffeners. There is usually a high probability of damage detection for a class 2 structure because of fuel or pressure leakage, that is, "leak-before-break" design is characteristic of class 2 structures.

• ### FAILURE CONSIDERATIONS P3

Structural arrangements. 2 structures, including pressurized cabins and pressure vessels, relatively large amounts of damage may be contained by providing tear straps or stiffeners. There is usually a high probability of damage detection for a class 2 structure because of fuel or pressure leakage, that is, "leak-before-break" design is characteristic of class 2 structures. Class 3 structures are usually designed to provide a specified percentage of the original strength, that is, a specified residual strength, during and subsequent to the failure of one element....

• ### CYTOKERATINS – TOOLS IN ONCOLOGY

The second section “HLA and non-MHC genes, Immune Response, and Gene Expression Studies” is dedicated to the molecular and immunological processes of AS. HLA- B*27 is a unique HLA Class I molecule: anchoring peptides in the binding grove of B pocket must have an arginine at the P2, and the free thiol Cys67 residue made B*27 easy to form homodimers in the extracellular domain. Twin studies suggest that the HLA-B*27 accounts for more than 50% of AS susceptibility. Until July 2011, 82 subtypes were described based on nucleotide differences.

• ### Báo cáo khoa học: How to remain nonfolded and pliable: the linkers in modular a-amylases as a case study

The primary structure of linkers in a new class of modulara-amylases con-stitutes a paradigm of the structural basis that allows a polypeptide to remain nonfolded, extended and pliable. Unfolding is mediated through a depletion of hydrophobic residues and an enrichment of hydrophilic resi-dues, amongst which Ser and Thr are over-represented.

• ### Báo cáo khoa học: Anaerobic sulfatase-maturating enzyme – A mechanistic link with glycyl radical-activating enzymes?

Sulfatases form a major group of enzymes present in prokaryotes and eukaryotes. This class of hydrolases is unique in requiring essential post-translational modification of a critical active-site cysteinyl or seryl residue to Ca-formylglycine (FGly).

• ### Báo cáo khoa học: Directed evolution of a histone acetyltransferase – enhancing thermostability, whilst maintaining catalytic activity and substrate speciﬁcity

Histone acetylation plays an integral role in the epigenetic regulation of gene expression. Transcriptional activity reflects the recruitment of oppo-sing classes of enzymes to promoter elements; histone acetyltransferases (EC 2.3.1.48) that deposit acetyl marks at a subset of histone residues and histone deacetylases that remove them.

• ### Báo cáo khoa học: A vertebrate slow skeletal muscle actin isoform

Salmonids utilize a unique, class II isoactin in slow skeletal muscle. This actin contains 12 replacements when compared with those from salmonid fast skeletal muscle, salmonid cardiac muscle and rabbit skeletal muscle. Substitutions are confined to subdomains 1 and 3, and most occur after residue 100. Depending on the pairing, the ‘fast’, ‘cardiac’ and rabbit actins share four, or fewer, substitutions.
