#1
Hitoshi Tsujimoto, Joyce M Sakamoto, Jason L Rasgon
The bed bug Cimex lectularius is a blood-feeding re-emerging annoyance pest insect that has the ability to transmit Trypanosoma cruzi under experimental laboratory conditions. Aquaporins (AQPs) are water channel proteins that are essential in biological organisms. C. lectularius are constantly exposed to water-related stress, suggesting that AQPs may offer novel control avenues. We identified and cloned four AQPs from C. lectularius, assessed tissue and lifestage-specific expression, and characterized biochemical functions in vitro and in vivo...

PURPOSE: To date, four synovial plicae are classically described in the knee. We report a previously undescribed new inferior patellar plica, named "bib-like plica" (BLP, referring to its morphology) related to specific symptoms of atypical recurrent anterior knee pain in the presence of a locked or pseudo-locked knee. We describe this anatomical structure, and assess its clinical relevance in daily practice in terms of clinical pattern and long-term follow-up outcome after arthroscopic excision...

Ismael Galván, Carlos Alonso-Alvarez
The evolution of honest animal communication is mostly understood through the handicap principle, which is intrinsically dependent on the concept of individual quality: low-quality individuals are prevented from producing high-quality signals because if they did so, they would pay greater production costs than high-quality individuals. We tested an alternative explanation for the black bib size of male house sparrows Passer domesticus, an honest signal of quality whose expression is negatively related to levels of the pigment pheomelanin in its contituent feathers...

Herein three novel cobalt metal-organic frameworks (Co-MOFs) with similar ingredients, [Co(bib)(o-bdc)]∞ (1), [Co2(bib)2(m-bdc)2]∞ (2), and {[Co(bib)(p-bdc)(H2O)](H2O)0.5}∞ (3), have been synthesized from the reaction of cobalt nitrate with 1,4-bis(imidazol-1-yl)benzene (bib) and structure-related aromatic acids (1,2-benzenedicarboxylic acid = o-bdc, 1,3-benzenedicarboxylic acid = m-bdc, and 1,4-benzenedicarboxylic acid = p-bdc) by the solvothermal method. It is aimed to perform systematic research on the relationship among the conformation of benzoate acid, lattice dimension of Co-MOF, and pore diameter of MOF-derived carbon composite...

Theory predicts trade-offs between pre- and postcopulatory sexually selected traits. This relationship may be mediated by the degree to which males are able to monopolise access to females, as this will place an upper limit on the strength of postcopulatory selection. Furthermore, traits that aid in mate monopolization may be costly to maintain and may limit investment in postcopulatory traits, such as sperm performance. Australian painted dragons are polymorphic for the presence or absence of a yellow gular patch ('bibs'), which may aid them to monopolise access to females...

Background: The use of foodbanks has risen sharply in the UK; however, the epidemiology of UK food insecurity is undeveloped. This study contributes to the field by analysing socio-demographic risk factors for food insecurity in a female, ethnically diverse population. Methods: Data from the Born in Bradford (BiB) cohort were matched with data on food insecurity from the nested BiB1000 study (N = 1280). Logistic regression was used to model food insecurity in relation to ethnicity and socio-demographic factors...

Rapidly assaying the diversity of a bacterial species present in a sample obtained from a hospital patient or an environmental source has become possible after recent technological advances in DNA sequencing. For several applications it is important to accurately identify the presence and estimate relative abundances of the target organisms from short sequence reads obtained from a sample. This task is particularly challenging when the set of interest includes very closely related organisms, such as different strains of pathogenic bacteria, which can vary considerably in terms of virulence, resistance and spread...

Previous studies in our lab have described kinematic difference between grasp-to-eat and grasp-to-place movements, whereby participants produce smaller maximum grip apertures (MGAs) when grasping to bring the item to the mouth than when grasping to bring the item to a container near the mouth. This task difference is limited to right-handed movements, regardless of handedness; it has, therefore, been interpreted as evidence of left-hemisphere lateralization of the grasp-to-eat and other hand-to-mouth grasping movements...

BACKGROUND: Since 2008, use of food banks has risen sharply in the UK; however, evidence on the epidemiology of UK food insecurity is sparse. The aim of this study was to describe the trajectory of common mental disorder across the pre-pregnancy, pregnancy and postnatal period for food secure compared with food insecure women. METHODS: Data from the Born in Bradford (BiB) cohort, the nested BiB1000 study and primary care records were linked based on National Health Service (NHS) numbers...

The hydrothermal reactions of 1,2,4,5-cyclohexanetetracarboxylic acid (H4L) with CoCl2·2H2O and rigid or semi-rigid bis(imidazole) ligands were able to generate two Co(ii) coordination polymers (CPs), {[Co5(L)2(1,4-bimb)(μ3-OH)2(H2O)8]·2H2O}n (1), {[Co(L)0.5(1,4-bib)]·H2O}n (2) (1,4-bimb = 1,4-bis(imidazol-1-ylmethyl)benzene, 1,4-bib = 1,4-bis(1H-imidazol-1-yl)benzene). CPs 1 and 2 were structurally characterized by elemental analysis, IR spectroscopy, X-ray powder diffraction and single crystal X-ray diffraction...

BACKGROUND: Evidence suggests that the process of taking part in health research can improve participants' health, independent of any intended intervention. However, no research has yet explored whether these effects differ across socioeconomic groups. If the effect of mere participation in health research also has a social gradient this could increase health inequalities and bias research results. This study used the Born in Bradford family cohort (BIB) to explore whether simply taking part in BIB had improved participants' health and, if so, whether this effect was mediated by socioeconomic status...

Transcript prediction can be modeled as a graph problem where exons are modeled as nodes and reads spanning two or more exons are modeled as exon chains. Pacific Biosciences third-generation sequencing technology produces significantly longer reads than earlier second-generation sequencing technologies, which gives valuable information about longer exon chains in a graph. However, with the high error rates of third-generation sequencing, aligning long reads correctly around the splice sites is a challenging task...

We report a compact, fiber-laser-based, high-repetition-rate picosecond source for the ultraviolet (UV), providing multi-tens of milliwatt of average power across 329-348 nm. The source is based on internal sum-frequency-generation (SFG) in a singly resonant optical parametric oscillator (OPO), synchronously pumped at 532 nm by the second harmonic of a picosecond Yb-fiber laser at 80 MHz repetition rate. Using a 30-mm-long single-grating MgO:sPPLT crystal for the OPO and a 5-mm-long BiB<sub>3</sub>O<sub>6</sub> crystal for intracavity SFG, we generate up to 115 mW of average UV power at 339...

A recent full species-level phylogeny of tits, titmice and chickadees (Paridae) has placed the Chinese endemic black-bibbed tit (Poecile hypermelaenus) as the sister to the Palearctic willow tit (P. montanus). Because this sister-group relationship is in striking disagreement with the traditional affiliation of P. hypermelaenus close to the marsh tit (P. palustris) we tested this phylogenetic hypothesis in a multi-locus analysis with an extended taxon sampling including sixteen subspecies of willow tits and marsh tits...

Here we examine the potential of serial Broad Ion Beam (BIB) Ar(+) ion polishing as an advanced serial section tomography (SST) technique for destructive 3D material characterisation for collecting data from volumes with lateral dimensions significantly greater than 100µm and potentially over millimetre sized areas. Further, the associated low level of damage introduced makes BIB milling very well suited to 3D EBSD acquisition with very high indexing rates. Block face serial sectioning data registration schemes usually assume that the data comprises a series of parallel, planar slices...

The design of nonlinear optical (NLO) materials with large NLO responses has been a challenge for materials scientists and chemists. Recently, organic polymers have received attention regarding their NLO properties and fast nonlinear response, and clusters involving delocalized dπ-pπ systems and conjugated dπ-pπ systems are expected to be a new class of NLO materials. Metal-organic coordination polymers combine the advantages of the organic and inorganic species. Thus far, tuning the third-order NLO properties of these materials has been a significant challenge...

We report on an efficient high-power, widely tunable femtosecond optical parametric oscillator in BiB<sub>3</sub>O<sub>6</sub>, synchronously pumped by a frequency-doubled mode-locked Yb:KGW laser at 515 nm. Using collinear type I (o→e+e) phase matching, a resonant wavelength range of 688-1057 nm at a 151-MHz repetition rate is demonstrated, with a tunable idler range of 1150-1900 nm. The output power at 705 nm is 1.09 W for 3.6 W pump power exceeding 30% conversion efficiency. Near-transform-limited pulses down to 71 fs are achieved by deploying extracavity dispersion compensation in a pair of SF6 prisms...

Aquaporins (AQPs) are a family of membrane-bound proteins, originally described as water-channels, that broadly exist in prokaryotic and eukaryotic cells. However, some AQPs can transport small molecules (e.g. urea, glycerol) along with or preferentially to water. Previous work in the mosquitoes Aedes aegypti and Anopheles gambiae have characterized the molecular expression of one or more AQP genes and shown that they are involved in water homeostasis after blood feeding, tolerance to dehydration and heat stresses, and development of Plasmodium falciparum in the mosquito...

BACKGROUND AND AIM: The use of BioEnterics intragastric balloon (BIB) is progressively increasing, owing to the fact that morbid obesity becomes a global epidemic together with risks of bariatric surgery. Yet, the possible local BIB effect on gastric mucosa is not clearly elucidated. The aim of the current study was to assess the histological changes occurring in the gastric mucosa post-BIB insertion. METHODS: Gastric mucosa biopsy was obtained from 87 cases of morbid obesity both pre-BIB and 6 months post-BIB insertion to compare the local changes by histological and immunohistochemical analysis...
