Colorectal cancer is one of the most common malignant tumors in China. In 2012 one million thirty six thousand cases of colorectal cancer were diagnosed all over the world, two hundred fifty three thousand cases were diagnosed in China (accounted for 18.6%). China has the largest number of new cases of colorectal cancer in the world. Colorectal cancer has becoming a serious threat of Chinese residents' health. In 2010, the National Ministry of Health organized colorectal cancer expertise of the Chinese Medical Association to write the "Chinese Protocol of Diagnosis and Treatment of Colorectal Cancer" (2010edition), and publish it publicly...

STUDY QUESTION: In ICSI patients with high risk of ovarian hyperstimulation syndrome (OHSS), are antagonist cycles triggered by gonadotropin releasing hormone (GNRH) agonist with a specialized luteal support regimen associated with comparable ongoing pregnancy rate (OPR) and less OHSS than those triggered by hCG? SUMMARY ANSWER: In antagonist ICSI cycles, GnRH agonist triggering with a specialized luteal support regimen is associated with comparable OPR to those triggered by hCG but may be less likely to be associated with OHSS...

Polythiacalix[4]amides as a novel category of polyamides, with high sorption capability towards some environmentally hazardous metal cations, especially Hg2+, have been synthesized via direct polycondensation protocol using a thiacalix[4] arene dicarboxylic acid and commercial diamines. The polyamides were obtained in high yields and possess inherent viscosities in the range of 0.55-0.75 dl/g. The photophysical characteristic was studied by looking for the maximum absorption wavelength of each polymer using UV absorption spectroscopy...

The presence of residues within the root canal after post-space preparation can influence the bond strength between resin cement and root dentin when using fiberglass posts (FGPs). Currently, there is no consensus in the literature regarding what is the best solution for the removal of debris after post-space preparation. This systematic review involved "in vitro" studies to investigate if cleaning methods of the root canal after post-space preparation can increase the retention of FGPs evaluated by the push-out test...

T2*-weighted multi-echo gradient-echo magnetic resonance imaging and its reciprocal R2* are used in brain imaging due to their sensitivity to iron content. In patients with multiple sclerosis who display pathological alterations in iron and myelin contents, the use of R2* may offer a unique way to untangle mechanisms of disease. Coronal slices from 8 brains of deceased multiple sclerosis patients were imaged using a whole-body 7.0 Tesla MRI scanner. The scanning protocol included three-dimensional (3D) T2*-w multi-echo gradient-echo and 2D T2-w turbo spin echo (TSE) sequences...

BACKGROUND AND OBJECTIVES: Chronic kidney disease (CKD) is a global health burden and is independently associated with increased cardiovascular disease risk. Assessment of cardiovascular risk in the general population using prognostic models based on routinely collected risk factors is embedded in clinical practice. In CKD, prognostic models may misrepresent risk due to the interplay of traditional atherosclerotic and non-traditional risk factors. This systematic review's aim was to identify routinely collected risk factors for inclusion in a CKD-specific cardiovascular prognostic model...

The implementation of wireless sensor networks (WSNs) for monitoring the complex, dynamic, and harsh environment of underground coal mines (UCMs) is sought around the world to enhance safety. However, previously developed smart systems are limited to monitoring or, in a few cases, can report events. Therefore, this study introduces a reliable, efficient, and cost-effective internet of things (IoT) system for air quality monitoring with newly added features of assessment and pollutant prediction. This system is comprised of sensor modules, communication protocols, and a base station, running Azure Machine Learning (AML) Studio over it...

The Danish automated Vendlet V5s repositioning system is intended to reduce pressure ulcer risk in patients and work-related musculoskeletal disorders (MSDs) in caregivers. In two Belgian nursing homes, 13 residents with mobility levels C, D and E experienced the repositioning system, operated by 35 caregivers, for 4 weeks. Data about skin condition, nursing time needed for repositioning and MSD symptoms were collected. The use of the repositioning system was not associated with the development of nor a reduction in skin problems; the study included residents who were vulnerable to or already had pressure ulcers...

Attenuated Ca2+ -activated Cl- secretion has previously been observed in the model of dextran-sulfate-sodium (DSS)-induced colitis. Prior studies have implicated dysfunctional muscarinic signaling from basolateral membranes as the potential perpetrator leading to decreased Ca2+ -activated Cl- secretion. However, in our chronic model of DSS-colitis, Chrm3 transcript (1.028 {plus minus} 0.12 vs. 1.029 {plus minus} 0.27, p > 0.05) and CHRM3 protein expression (1.021 {plus minus} .24 vs. .928 {plus minus} .09, p > 0...

The green fabrication of nanoparticles (NPs) by using plants as reducing and capping agents involves energy efficient, less toxic, safer and simpler pathways. These pathways have been related to the rational use of numerous substances in fabrication of NPs and synthetic strategies, which have been mainly discussed in this article. The subject matter of this review is to discuss how a chemist can follow the green chemistry principles in terms of selection of substances and protocols used for NPs fabrication...

This paper reports that tertiary α-azidyl phenyl ketones can be transformed into enamides by treatment with FeBr2 at elevated temperature in DMF. The reaction proceeds via 1,2-benzoyl migration from α-carbon to the nitrogen atom, accompanied by expulsion of a nitrogen molecule. This protocol is suitable for the synthesis of N-(cyclopent-1-en-1-yl)benzamides, N-(cyclohex-1-en-1-yl)benzamides, and N-benzoyl-α-methyl enamines and provides a convenient approach toward isoquinolones.

PURPOSE OF REVIEW: Clinical MRI is of paramount importance for multiple sclerosis diagnosis but lacks the specificity to investigate the pathogenic mechanisms underlying disease onset and progression. The application of advanced magnetic resonance (MR) sequences allows the characterization of diverse and complex pathological mechanisms, granting insights into multiple sclerosis natural history and response to treatment. RECENT FINDINGS: This review provides an update on the most recent international guidelines for optimal standard imaging of multiple sclerosis and discusses advantages and limitations of advanced imaging approaches for investigating inflammation, demyelination and neurodegeneration...

SIGNIFICANCE: Glaucomatous nasal visual field abnormalities correspond to damage in the temporal raphe-where individual nerve bundles can be visualized. The ability to quantify structural abnormality in the raphe, with a clinically applicable protocol, sets the stage for investigating the raphe as a potential site for assessing early glaucoma. PURPOSE: To develop a clinically applicable imaging and analysis technique for identifying retinal nerve fiber bundle abnormalities in the temporal raphe...

BACKGROUND: Diabetes self-care activities, like, healthy diet, regular exercise, self-monitoring of blood glucose, and rational use of medicines are considered to play a vital role in establishing euglycemia. Health literacy among type 2 diabetes mellitus (T2DM) patients in Pakistan is very low, which is the most likely cause for poor clinical outcomes. This study is designed to investigate the impact of pharmacist-led educational intervention on glycemic control, self-care activities and disease knowledge among T2DM patients in Pakistan...
