Protophormia terraenovae (Robineau-Desvoidy) (Diptera: Calliphoridae) and Phormia regina (Meigen) (Diptera: Calliphoridae) are morphologically similar blow fly species commonly used for estimating postmortem intervals. Field collection and storage of adults can result in color changes, in particular on calypters and palps; often collected specimens show damage such as wing fray or fungal growth. We measured the frons width: total head width ratio using photographs (ImageJ version 1.49) to differentiate these two species...

BACKGROUND: Policy-makers promote a seek, test, treat and retain (STTR) strategy to expand HIV testing, support linkage and engagement in care, and enhance the continuous use of antiretroviral therapy for those HIV-infected. This HIV prevention strategy is particularly appropriate in correctional settings where HIV screening and treatment are routinely available yet many HIV-infected individuals have difficulty sustaining sufficient linkage and engagement in care, disease management, and viral suppression after prison release...

Petaled MoS2 electrodes grown hydrothermally from Mo foils are found to have an 800 nm, intermediate, MoSxOy layer. Similar petaled MoS2 films without this intermediate layer are grown on Au. X-ray photoelectron and Raman spectroscopies and transmission electron microscopy indicate the resulting petaled multilayer MoS2 films are frayed and exhibit single-layer, 1T-MoS2 behavior at the edges. We compare the electrocatalytic hydrogen evolution reaction activity via linear sweep voltammetry with Tafel analysis as well as the impedance properties of the electrodes...

We report the case of a 62-year-old woman who underwent laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and lymph node dissection for endometrial endometrioid carcinoma FIGO grade 1. Cytologic examination of the pelvic washing specimen showed an acellular matrix with frayed edges and cracking artifact. Upon investigation, it became apparent that this could represent hemostatic matrix Floseal(R) that had been used intraoperatively at the lymphadenectomy site. Laboratory replication of the cytologic findings with a Floseal(R) sample confirmed it...

The transitioning of the ectodomain of gp41 from a pre-hairpin to a six-helix bundle conformation is a crucial aspect of virus-cell fusion. To gain insight into the intermediary steps of the fusion process we have studied the pH and dodecyl phosphocholine (DPC) micelle dependent trimer association of gp41 by systematic deletion analysis of an optimized construct termed 17-172 (residues 528 to 683 of Env) that spans the fusion peptide proximal region (FPPR) to the membrane proximal external region (MPER) of gp41, by sedimentation velocity and double electron-electron resonance (DEER) EPR spectroscopy...

INTRODUCTION: Arborizing stromal meshwork fragments (ASMFs) have been proposed as a useful clue to differentiate mucin associated with mucinous adenocarcinoma from contaminating mucus during endobronchial ultrasound-guided transbronchial needle aspiration. Our aim was to retrospectively review cytology cases with mucinous material to determine the utility of ASMFs in diagnosing mucinous tumors. MATERIAL AND METHODS: Diff-Quik stained smears from archival cytology cases (N = 40) were reviewed, including adenocarcinomas with mucinous features, cystic mucinous neoplasms, and control cases with mucin contamination...

BACKGROUND: Karyotypic integrity is essential for the successful germline transmission of alleles mutated in embryonic stem (ES) cells. Classical methods for the identification of aneuploidy involve cytological analyses that are both time consuming and require rare expertise to identify mouse chromosomes. RESULTS: As part of the International Mouse Phenotyping Consortium, we gathered data from over 1,500 ES cell clones and found that the germline transmission (GLT) efficiency of clones is compromised when over 50 % of cells harbour chromosome number abnormalities...

Two bottlenecks impeding the genetic analysis of complex traits in rodents are access to mapping populations able to deliver gene-level mapping resolution and the need for population-specific genotyping arrays and haplotype reference panels. Here we combine low-coverage (0.15×) sequencing with a new method to impute the ancestral haplotype space in 1,887 commercially available outbred mice. We mapped 156 unique quantitative trait loci for 92 phenotypes at a 5% false discovery rate. Gene-level mapping resolution was achieved at about one-fifth of the loci, implicating Unc13c and Pgc1a at loci for the quality of sleep, Adarb2 for home cage activity, Rtkn2 for intensity of reaction to startle, Bmp2 for wound healing, Il15 and Id2 for several T cell measures and Prkca for bone mineral content...

In a large Level IV case series of 2,213 hip arthroscopies with the diagnosis of femoroacetabular impingement, the intraoperative status of the ligamentum teres (LT) was recorded as normal in 11%, frayed and/or partially torn in 88%, and completely torn in 1.5% of hips. Although specific physical examination maneuvers for detecting LT tears were not available early in the study period, thus limiting a detailed assessment of such tests, the authors identified that female gender, a lower lateral center edge angle, a higher Tonnis angle, and capsular laxity were all associated with complete LT tears...

BACKGROUND: Vitamin D dependent rickets type 1A (VDDR-1A) (OMIM#264700) is a rare, autosomal-recessively inherited disorder due to inactivating mutations in CYP27B1. It is characterized by early onset of rickets with hypocalcemia. We aimed to describe clinical, laboratory findings in VDDR-1A and report a novel homozygote truncating mutation NM_000785.3 c.403C>T (p.Q135*) in CYP27B1 which as far as we know is the first described mutation in Uzbek population. CASE: The patient was admitted with tetany at the age of 12 months...

Cyanobacterial blooms caused by water eutrophication have become a worldwide problem. Microcystins (MCs), especially microcystin-LR (MC-LR), released during cyanobacterial blooms exert great toxicity on fish and even lead to massive death. The present study mainly investigated the pathological damage and immune response of spleen, gut and gill in zebrafish exposed to MC-LR. Fish were exposed to 0, 1, 5 and 20 μg/L of MC-LR for 30 d. In zebrafish exposed to 5 and 20 μg/L MC-LR, edematous mitochondria, deformation of the nucleus and compaction of chromatin were observed in lymphocyte of spleen; frayed gut villi, exfoliation of epithelial cells and widespread cell lyses were observed in intestines; hyperemia in gill lamellae, epithelial tissue edema and uplift and lamellar fusion were observed in gill...

The objective of the study was to determine whether a less-invasive surgical technique used in cryptorchid horses, dogs and cats can be used successfully to remove retained testicles in pigs on farm. In total, 284 monolateral cryptorchid pigs underwent surgery on-farm condition, during which an incision was made over the inguinal ring and the undescended testicle was located for removal via identification of the vaginal process and the embryonic gubernaculum. A traction of these structures allowed the testis to pass through the deep and the superficial rings up to its exteriorisation outside the abdominal wall through the inguinal canal...

Since its discovery in 2003, murine norovirus (MNV) is still endemic in many rodent animal facilities. Our aim was to determine the risk of transmission of MNV (91% homology to MNV3) to embryo recipients and pups via assisted reproductive technologies, especially those which compromise the integrity of the zona pellucida. In vitro fertilization (IVF), assisted in vitro fertilization (AIVF) with reduced glutathione, intracytoplasmic sperm injection, and ovary transplantation were performed. Murine norovirus was detected by qualitative and quantitative reverse transcription polymerase chain reaction...

In nature, the folding of oligomers and polymers is used to generate complex three-dimensional structures, yielding macromolecules with diverse functions in catalysis, recognition, transport, and charge- and energy-transfer. Over the past 20-30 years, chemists have sought to replicate this strategy by developing new foldamers: oligomers that fold into well-defined secondary structures in solution. A wide array of abiotic foldamers have been developed, ranging from non-natural peptides to aromatics. The ortho-phenylenes represent a recent addition to the family of aromatic foldamers...
