Prior abdominal open surgery does not impair outcomes of laparoscopic colorectal surgery: a case–control study in 367 patients
Conclusion This large case–control study suggests that PAOS does not affect postoperative outcomes. For this reason, a systematic laparoscopic approach in patients with PAOS, even with midline incision, should be considered in colorectal surgery.

Management and short‐term outcome of malignant colorectal polyps in the north of England1
Conclusion Endoscopic management of a subgroup of MCPs appears safe. A clear resection margin (> 0 mm) appears sufficient to avoid surgery, except in locally advanced lesions (Kikuchi 3/Haggitt 4) which have a greater risk of residual cancer at surgery and lymph node metastasis.

Incidence of prostate, breast, lung and colorectal cancer following new consultation for musculoskeletal pain: A cohort study among UK primary care patients
The objective was to investigate associations between pain sites and specific cancers, and investigate the hypothesis that musculoskeletal pain is an early marker, rather than cause, of cancer. This was a cohort study in the General Practice Research Database. From a cohort of 46,656 people aged ≥50 years with a recorded musculoskeletal problem in 1996 but not during the previous 2 years, patients with a new consultation for back, neck, shoulder or hip pain in 1996 were selected and compared with 39,253 persons who had had no musculoskeletal consultation between 1994‐1996. Outcome was incidence of prostate, breast, lun...

Presence or absence of a positive pathological margin outperforms any other margin‐associated variable in predicting clinically relevant biochemical recurrence in Gleason 7 prostate cancer
Conclusions In Gleason 7 prostate cancer, positive pathological margin status was the only consistent margin‐derived variable determining biochemical failure. The presence of high‐grade disease at the margin may also have an impact on the development of clinically significant biochemical recurrence.

Systematic review of the incidence and prevalence of genital warts
Conclusions: The literature suggests that AGWs are widespread and the prevalence depends on study methodology as suggested by higher rates reported from routine genital examinations versus those from treatment records. However, there remains a need for more population-based studies from certain regions including Africa, Latin America and Southern Asia to further elucidate the global epidemiology of this disease.

Impact of intracoronary cell therapy on left ventricular function in the setting of acute myocardial infarction: a meta-analysis of randomised controlled clinical trials
Conclusion Intracoronary BMC treatment leads to a moderate improvement of LVEF and reduction of LVESV at 6 months that sustained at 12 months follow-up, without a clear significant effect on LVEDV, or infarct size. Furthermore, we found that intracoronary cell therapy is significantly associated with a reduction in recurrent AMI and readmission for heart failure, unstable angina or chest pain.

Combined use of liquid chromatography triple quadrupole mass spectrometry and liquid chromatography quadrupole time-of-flight mass spectrometry in systematic screening of pesticides and other contaminants in water samples.
Abstract As a suitable way for routine screening of pesticides and control of other organic contaminants in water, the combination of liquid chromatography triple quadrupole tandem mass spectrometry (LC-QqQ-MS/MS) and liquid chromatography-hybrid quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) has been applied to the analysis of 63 surface and waste water samples after conventional solid-phase extraction (SPE). The extracts were screened for 43 pesticides or degradation products by LC-QqQ-MS/MS achieving limits of detection (LOD) ranged from 0.04 to 2ngL(-1). Of the 43 selected pesticides, 33 were detected...

New way to quantify multiple steroidal compounds in wastewater by comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry.
Abstract The applicability of comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometry to the screening of steroidal compounds in wastewater is demonstrated. Advanced software was utilized to identify unknown compounds in complex two-dimensional chromatograms exploiting retention indices and two different mass spectral databases. Response factors calculated as a function of the individual mass spectra of six commercial standards at different concentrations were used to develop a model allowing the quantitation of all steroidal compounds identified in the sample. The model, base...

Application of Multivariate Curve Resolution Alternating Least Squares (MCR-ALS) to remote sensing hyperspectral imaging.
Abstract The application of the MCR-ALS method is demonstrated on two simulated remote sensing spectroscopic images and on one experimental reference remote sensing spectroscopic image obtained by the Airborn Visible/Infrared Imaging Spectrometer (AVIRIS). By application of MCR-ALS, the spectra signatures of the pure constituents present in the image and their concentration distribution at a pixel level are estimated. Results obtained by MCR-ALS are compared to those obtained by other methods frequently used in the remote sensing spectroscopic imaging field like VCA and MVSA. In the case of the analysis of the expe...

Ligand-based discovery of N-(1,3-dioxo-1H,3H-benzo[de]isochromen-5-yl)-carboxamide and sulfonamide derivatives as thymidylate synthase A inhibitors.
Abstract Phenolnaphthalein derivatives show potential for pharmacological activity as inhibitors of thymidylate synthase (TS) but difficulties in their synthesis and derivatization hinder their development. A deconstruction approach aimed at identifying a suitable new scaffold was proposed. A new scaffold was identified and two compound libraries based on this scaffold were designed. The carboxamide library (Library B) showed specific inhibition activity against Escherichia coli TS, whereas the sulfonamide library (Library C) showed a non-specific inhibition profile against hTS.

The impact of child sexual abuse on the course of bipolar disorder: a systematic review
Conclusions: Child sexual abuse is associated (either directly or indirectly) with some clinical phenomena that represent a more severe form of bipolar disorder. Although such a traumatic experience may directly affect the development of posttraumatic stress disorder, the effects of early sexual abuse on later suicidal behavior, substance abuse, and psychotic symptoms may operate through the mediating influences of certain psychopathological or neurobiological variables.

Flawed forecasting – when science fiction gets it wrong | Jenny Rohn
Forget jetpacks – predicting social change can be a fictional challengeDespite my strong public advocacy of Lab Lit fiction, I have always been a huge science fiction fan too.

Being taken to see the first Star Wars movie at the age of nine was akin to a religious experience for me.I devoured the genre in print, too.

Synthesis and evaluation of thiazolidinedione and dioxazaborocane analogues as inhibitors of AI-2 quorum sensing in Vibrio harveyi.
Abstract Two focused libraries based on two types of compounds, that is, thiazolidinediones and dioxazaborocanes were designed. Structural resemblances can be found between thiazolidinediones and well-known furanone type quorum sensing (QS) inhibitors such as N-acylaminofuranones, and/or acyl-homoserine lactone signaling molecules, while dioxazaborocanes structurally resemble previously reported oxazaborolidine derivatives which antagonized autoinducer 2 (AI-2) binding to its receptor. Because of this, we hypothesized that these compounds could affect AI-2 QS in Vibrio harveyi. Although all compounds blocked QS, th...

Discharge within 24 to 72 Hours of Colorectal Surgery Is Associated with Low Readmission Rates when Using Enhanced Recovery Pathways
Conclusions: Combining laparoscopy with an ERP optimizes patient care in colorectal surgery. The combination permits early discharge; 38% were discharged within 2 days and 62% within 3 days of surgery, with low readmission rates. These results support that early DoD is possible without compromising patient safety or increasing readmission rates. This might be a marker for low readmission rate, and suggests that readmission rate alone might not be an adequate marker of quality.

Recent trends in resistance to cell envelope–active antibacterial agents among key bacterial pathogens
Cell envelope–active agents, particularly β‐lactams, play a pivotal role in the treatment of bacterial infections and the extent to which their activity is affected by the emergence of multidrug‐resistant organisms is of concern. We analyzed the Surveillance Network (TSN) database to evaluate resistant trends for key cell envelope–active drugs among ESKAPE pathogens. Analysis demonstrated that the activity of these drugs has been notably influenced by the emergence of multidrug resistance; this was especially evident for the β‐lactam drugs. For example, Acinetobacter baumannii resistance to imipenem increased f...

HTS by NMR of Combinatorial Libraries: A Fragment-Based Approach to Ligand Discovery.
Abstract Fragment-based ligand design (FBLD) approaches have become more widely used in drug discovery projects from both academia and industry, and are even often preferred to traditional high-throughput screening (HTS) of large collection of compounds (>10(5)). A key advantage of FBLD approaches is that these often rely on robust biophysical methods such as NMR spectroscopy for detection of ligand binding, hence are less prone to artifacts that too often plague the results from HTS campaigns. In this article, we introduce a screening strategy that takes advantage of both the robustness of protein NMR spectrosc...

Effector Kinase Coupling Enables High-Throughput Screens for Direct HIV-1 Nef Antagonists with Antiretroviral Activity.
Abstract HIV-1 Nef, a critical AIDS progression factor, represents an important target protein for antiretroviral drug discovery. Because Nef lacks intrinsic enzymatic activity, we developed an assay that couples Nef to the activation of Hck, a Src family member and Nef effector protein. Using this assay, we screened a large, diverse chemical library and identified small molecules that block Nef-dependent Hck activity with low micromolar potency. Of these, a diphenylpyrazolo compound demonstrated submicromolar potency in HIV-1 replication assays against a broad range of primary Nef variants. This compound binds di...

Characterization of a Heavy Metal Translocating P-Type ATPase Gene from an Environmental Heavy Metal Resistance Enterobacter sp. Isolate.
Abstract Heavy metals are common contaminants found in polluted areas. We have identified a heavy metal translocating P-type ATPase gene (hmtp) via fosmid library and in vitro transposon mutagenesis from an Enterobacter sp. isolate. This gene is believed to participate in the bacterium's heavy metal resistance traits. The complete gene was identified, cloned, and expressed in a suitable Escherichia coli host cell. E. coli W3110, RW3110 (zntA::Km), GG48 (ΔzitB::Cm zntA::Km), and GG51 (ΔzitB::Cm) were used to study the possible effects of this gene for heavy metal (cadmium and zinc in particular) resistance.
