Structure-function analysis of HsiF, a gp25-like component of the type VI secretion system, in Pseudomonas aeruginosa.Bacterial pathogens use a range of protein secretion systems to colonize their host. One recent addition to this arsenal is the type VI secretion system (T6SS), which is found in many Gram-negative bacteria. The T6SS involves 12-15 components, including a ClpV-like AAA(+) ATPase. Moreover, the VgrG and Hcp components have been proposed to form a puncturing device, based on structural similarity to the tail spike components gp5/gp27 and the tail tube component gp19 of the T4 bacteriophage, respec ...201121873404
Gastrectomy as a secondary surgery for stage IV gastric cancer patients who underwent S-1-based chemotherapy: a multi-institute retrospective study.BACKGROUND: Current advances in chemotherapy provide opportunities for stage IV gastric cancer patients with distant metastasis to undergo potentially curable resection.

Geofold: Topology-based protein unfolding pathways capture the effects of engineered disulfides on kinetic stability.Protein unfolding is modeled as an ensemble of pathways, where each step in each pathway is the addition of one topologically possible conformational degree of freedom. Starting with a known protein structure, GeoFold hierarchically partitions (cuts) the native structure into substructures using revolute joints and translations. The energy of each cut and its activation barrier are calculated using buried solvent accessible surface area, side chain entropy, hydrogen bonding, buried cavities, and ...201122189917

Are thyroid hormone concentrations at birth associated with subsequent autism diagnosis?Thyroid hormones substantially influence central nervous system development during gestation. We hypothesized that perturbations of early thyroid profiles may contribute to the development of autism spectrum disorders (ASD). Thyroid pathways could provide a mechanism by which environmental factors that affect the thyroid system may impact autism occurrence or phenotypic expression. We investigated whether thyroxine (T4) levels at birth are associated with subsequent ASD, using two existing Calif ...201121882364
[Thyreopathy in primary care].Thyroid gland disorders, as the core of all endocrinopathies, affect 5-7% of the population of the Czech Republic, with women being affected 6-8 times more often than men. Clinically, thyreopathies are divided into hormonal production disorders and morphology disorders. Thyroid hormones fT3, fT4 and TSH serum levels determine the diagnosis of a thyroid gland disorder. Primary hypothyreosis is characterized by reduced fT4 and increased TSH. Low T3 syndrome is a protective reaction of the organism ...201121957775

[Rectal cancer: The radiation basis of radiotherapy, target volume].Since the implementation of preoperative chemoradiotherapy and mesorectal excision, the 5-year rates of locoregional failures in T3-T4 N0-N1 M0 rectal cancer fell from 25-30% thirty years ago to 5-8% nowadays. A critical analysis of the locoregional failures sites and mechanisms, as well as the identification of nodal extension, helps the radiation oncologist to optimize the radiotherapy target definition. The upper limit of the clinical target volume is usually set at the top of the third sacra ...201121890393
modulation of the processive abasic site lyase activity of a pyrimidine dimer glycosylase.the repair of cis-syn cyclobutane pyrimidine dimers (cpds) can be initiated via the base excision repair (ber) pathway, utilizing pyrimidine dimer-specific dna glycosylase/lyase enzymes (pdgs). however, prior to incision at lesion sites, these enzymes bind to non-damaged dnas through charge-charge interactions. following initial binding to dna containing multiple lesions, the enzyme incises at most of these sites prior to dissociation. if a subset of these lesions are in close proximity, cluster ...201121889915
two pathways for rnase e action in escherichia coli in vivo and bypass of its essentiality in mutants defective for rho-dependent transcription termination.the endonuclease rnase e of escherichia coli is essential for viability, but deletion of its c-terminal half (cth) is not lethal. rnase e preferentially acts on 5'-monophosphorylated rna whose generation from primary transcripts is catalysed by rpph, but δrpph strains are viable. here we show that the rnase e-δcth δrpph combination is lethal, and that the lethality is suppressed by rho or nusg mutations impairing rho-dependent transcription termination. lethality was correlated with defects in b ...201122026368

positive correlation between type 1 and 2 iodothyronine deiodinases activities in human goiters.type 1 (d1) and 2 (d2) iodothyronine deiodinases are selenocysteine-containing enzymes that catalyze the deiodination of t4 to t3 in the thyroid and in peripheral tissues. despite their importance to the plasma t3 pool in human beings, there are few studies about their behavior in human thyroids. in order to better understand iodothyronine deiodinase regulation in the thyroid gland, we studied thyroid tissue samples from follicular adenoma (ad, n = 5), toxic diffuse goiter (tdg, n = 6), nontoxic ...201122207295

Solution structure of a minor and transiently formed state of a T4 lysozyme mutant.Proteins are inherently plastic molecules, whose function often critically depends on excursions between different molecular conformations (conformers). However, a rigorous understanding of the relation between a protein's structure, dynamics and function remains elusive. This is because many of the conformers on its energy landscape are only transiently formed and marginally populated (less than a few per cent of the total number of molecules), so that they cannot be individually characterized ...201121857680
