Joerg Feldmann, Andrea Raab, Eva M Krupp
This article is aimed at researchers interested in organic molecules which contain a heteroatom but who have never considered using inductively coupled plasma mass spectrometry (ICPMS) or who have used ICPMS for years and developed numerous methods for analysis of target elemental species. We try to illustrate (1) that ICPMS has been very useful for speciation analysis of metal(loid) target species and that there is now a trend to replace the costly detector with cheaper detection systems for routine target analysis, and (2) that ICPMS has been used and will be used even more in the future for non-targeted analysis of elements which are not normally associated with ICPMS analysis, such as non-metals such as sulfur, phosphorus, chlorine and fluorine...

INTRODUCTION: Dyspnea due to bilateral vocal cord palsy after total thyroidectomy (BVCPATT) is a life-threatening complication; nevertheless, we try to avoid tracheotomy. METHODS: Using normalized glottal area (NGA), we retrospectively studied 14 patients with BVCPATT. Nine patients without dyspnea were treated conservatively, while five with dyspnea received immediate bilevel positive air-way pressure (BiPAP) treatment. Both right and left recurrent nerves were grossly intact during surgery...

BACKGROUND: The clustering pattern and motifs give immense information about any biological data. An application of machine learning algorithms for clustering and candidate motif detection in miRNAs derived from exosomes is depicted in this paper. Recent progress in the field of exosome research and more particularly regarding exosomal miRNAs has led much bioinformatic-based research to come into existence. The information on clustering pattern and candidate motifs in miRNAs of exosomal origin would help in analyzing existing, as well as newly discovered miRNAs within exosomes...

We should start as we mean to go on and try to avoid the confusion most of us experience when bombarded with acronyms with overstated significations. You will be familiar with the situation, you are in a seminar or a meeting and someone who has been using a set of acronyms for years, includes them in sentence after sentence that has you lost because you don't know what some or most of them stand for. Even worse when scientists start making verbs out of them, CRISPR seems to have fallen into this category; how many of us have heard someone asking if a mutation can be CRISPRed! Does it matter though? We are all familiar with informal language in scientific talks and discussions which is replaced by more formal dialect when research is published or presented to the general public...

Cephalomedullary fixations are commonly used in the treatment of intertrochanteric fractures. In clinical practice, one of the difficulties is when we exit the guide wire in a wrong position of femoral neck and insert near the hole again, the guide wire often flow into the previous track. This study develops a surgical technique to direct the guide wire to slip away the previous track and slip into a right position. When guide wire is exited to the cortex of femoral, we let the wire in and out at the cortical layer for several times to enlarge the entry hole...

Those of us who take care of women with blood disorders have few data on which to base our management of thrombocytopenia in pregnancy, particularly immune thrombocytopenia purpura (ITP). We extrapolate from the management of ITP in nonpregnant individuals and try to raise platelet counts in an attempt to meet the bleeding challenges of childbirth. Thirty years ago we believed that ITP conferred fetal risks similar to those conferred by alloimmune thrombocytopenia. This article is protected by copyright. All rights reserved...

Although neoadjuvant treatment such as radiotherapy, even chemoradiotherapy has already widely used in middle-low rectal cancer, surgery remains the mainstay of therapy for patients with rectal cancer. Because neoadjuvant chemoradiotherapy combined with surgery was adopted for the locally advanced rectal cancer as a standard treatment based on guidelines, postoperative complications of rectal cancer surgery caused surgeons attention and concern gradually. Some severe complications should seriously affect patient's quality of life, even patient's survival...

CONTEXT: Yttria partially stabilized tetragonal zirconia polycrystalline restorations have gained widespread use because of its enhanced strength and esthetics. During the try-in process, zirconia is likely to be contaminated with saliva. This contamination leads to a clear weakening of the bond between restorative material and cement. For this reason, zirconia surface should be cleaned before cementation. Hence, the purpose of this study is to compare the shear bond strength of zirconia restorations cleansed with various surface cleansing protocols bonded with two different resin cements...

Acute spinal cord injury (ASCI) is common and no consensuses have been reached regarding timing of surgical decompression. This article highlights the main issues regarding surgical management of ASCI patients. The importance of timing of surgery along with physiological stability of the cord, and indications for surgery has been discussed to facilitate better understanding of the condition. The importance of the type of injury to the spinal column, besides the cord injury, is also discussed. A brief review of relevant literature has been done to try and answer the question whether early or late surgical treatment for ASCI is better than conservative management, reflecting the ethos of treatment for these problems in Robert Jones And Agnes Hunt Orthopaedic Hospital in Oswestry...

Recently, there has been an upsurge in the use of naturally available fuels for solution combustion synthesis (SCS) of nanoparticles. Although many reports suggest that these biofuels pose less harm to the environment, their strategic advantages and reliability for making NPs has not been discussed. In the present work, we try to address this issue using plant extracts as biofuels for the SCS of zinc oxide nanoparticles as a model system. In the present work, combustion synthesis of ZnO NPs using lactose and aqueous leaf extracts of Abutilon indicum, Melia azedarach, Indigofera tinctoria as biofuels has been carried out...

Obstructive sleep apnea is an exciting area for orthodontists to be involved. The level of awareness of sleep apnea and related health issues is growing rapidly. The demand of integrating sleep into the orthodontic practice shortly will be driven by the need of the societies as some of our patients will be shortly coming into our offices aware of sleep apnea. However, with our busy clinical orthodontic practice, the need of condense short review become more demanding. Therefore, this review will try to summarize the clinical and orthodontic observation in the diagnoses of adult obstructive sleep apnea with clinical application in orthodontic practice...

Obesity increases the risk of heart failure (HF), which continues to be a significant proportion of all cardiovascular diseases and affects increasingly younger populations. The cross-talk between adipose and the heart involves insulin resistance, adipokine signaling and inflammation, with the capacity of adipose tissue to mediate hemodynamic signals, promoting progressive cardiomyopathy. Areas covered: From a therapeutic perspective, there is not yet a single obesity-related pathway that when addressed, can ameliorate cardiomyopathy in obese patients and this is a matter of ongoing research...
