Purpose To investigate whether ultrasound follow-up for the detection of postpartum retained products of conception (RPOC) in women considered at risk for this condition may allow for early diagnosis. Methods Parturients at risk for RPOC underwent an ultrasound exam on the second postpartum day. Based on the ultrasound findings, women were either: (1) discharged to routine postpartum care in cases of normal scans, (2) invited for follow-up in cases of abnormal scans. We retrospectively analyzed the rates of women requiring uterine evacuation due to persistent abnormal scans...

Purpose The implementation of a reformed curriculum for undergraduate medical education with a problem-oriented focus and more bedside teaching in small groups increases the academic teaching workload. The aim of this study was to investigate whether this increase in teaching duties is associated with an increase in report turnaround times of radiologists or increased unplanned absence during term times compared with term breaks (lecture-free periods) and over the whole period under investigation. Materials and Methods The database of all radiological examinations performed at a large German university hospital was retrospectively analyzed for a two-year period from the winter term 2011/12 to the summer term 2013...

Meralgia paraesthetica (MP) is a condition originally described by Bernhardt in 1878 and was eventually named by Roth in 1895. It is caused by compression of the lateral femoral cutaneous nerve (LFCN) resulting in varying types of discomfort. Severity of the symptoms can range from mildly uncomfortable to painfully disabling. In this article we discuss 2 patients with a LFCN injury occurring as a result of laparoscopic ventral rectopexy (LVR). The first patient is a 46-year-old female who reported pain and dysesthesia in the left groin and the anterolateral thigh, 2 days post LCR...

BACKGROUND: Failed back surgery syndrome (FBSS) has a high incidence following spinal surgery, is notoriously refractory to treatment, and results in high health care utilization. Spinal cord stimulation (SCS) is a well-accepted modality for pain relief in this population; however, until recently magnetic resonance imaging (MRI) was prohibited due to risk of heat conduction through the device. OBJECTIVES: We examined trends in imaging use over the past decade in patients with FBSS to determine its impact on health care utilization and implications for patients receiving SCS...

BACKGROUND: Cervical disc disease is a common and occasionally disabling condition, occurring as a natural consequence of aging in the vast majority of the adult population. Percutaneous epidural neuroplasty (PEN) has been used to deliver highly concentrated drugs for chronic neck pain and to prevent scarring in cases refractory to conventional epidural blocks. However, the clinical course after PEN in cervical disc disease is not well-documented. OBJECTIVE: The purpose of this study was to evaluate the efficacy of cervical PEN for single-level cervical disc disease...

BACKGROUND: Radiofrequency (RF) ablation for denervation has been utilized for decades in chronic pain management. This relies on the proper targeting of the affected nerve which may be obtained by creating an ablation lesion with a shape and volume that optimizes targeting. Various systems designed to improve lesion size are available. These include cooling the active tip (cooled-RF) and protruding the RF electrode outside the active tip (PERF). OBJECTIVES: This study compares lesion volumes of 3 commercially available RF systems: cooled-RF, "V" shaped active cannula and protruding electrode (18 g and 20 g), and monopolar RF (MRF; 16 g, 18 g, and 20 g)...

BACKGROUND: Individuals with chronic whiplash associated disorders (WAD) present persistent pain in the absence of structural pathology. In these people, altered central pain processing and central sensitization are observed. The role of personal factors, such as gender and age, on pain processing mechanisms in chronic WAD, however, is still unclear. OBJECTIVES: This study investigated possible gender- and age-related differences in self-reported and experimental pain measurements in people with chronic WAD...

BACKGROUND: Complex regional pain syndrome type I (CRPS-I), also called algodystrophy, is a complex syndrome characterized by limb pain, edema, allodynia, hyperalgesia and functional impairment of bone with a similar clinical picture of osteoporosis, including an increased release of various pro-inflammatory neuropeptides and cytokines. Several treatments have been proposed for CRPS-I, but due to the poor outcome of conventional drugs and the invasiveness of some techniques, expectations are now directed towards new resources that could be more effective and less invasive...

The groundbreaking discovery that lower levels of insulin/IGF-1 signaling (IIS) can induce lifespan extension was reported 24 years ago in the nematode Caenorhabditis elegans. In this organism, mutations in the insulin/IGF-1 receptor gene daf-2 or other genes in this pathway can double lifespan. Subsequent work has revealed that reduced IIS (rIIS) extends lifespan across diverse species, possibly including humans. In C. elegans, IIS also regulates development into the diapause state known as dauer, a quiescent larval form that enables C...

BACKGROUND/AIMS: Osteoarthritis (OA) is a degenerative joint disease characterized by articular cartilage degradation. The degradation of the extracellular matrix (ECM) of chondrocyte is closely associated with the destruction of joints in OA patients. lncRNAs are non-coding segments of RNA that possess important regulatory functions at the cellular level and in a variety of pathophysiological processes. The present study was conducted to investigate whether lncRNA-CIR regulated the expression of MMP13 as a sponge of miR-27 in OA...

Sepsis-induced myeloid-derived suppressor cells (MDSCs) contribute to immunosuppression associated with sepsis. We reported that the CCAAT enhancer-binding protein C/EBPβ activates microRNA (miR)-21 and miR-181b expressions, which induce transcription factor NFI-A to support the generation and expansion of MDSCs in the bone marrow and spleens of septic mice. Here, using a conditional knockout mouse model lacking C/EBPβ in the myeloid lineage, we find that without C/EBPβ, myeloid progenitor cells could not express miR-21 or miR-181b, and ectopic expression of C/EBPβ in the C/EBPβ-deficient myeloid progenitors activated the expression of the two miRNAs...

Although veterinary anthelmintics represent an important source of environmental pollution, the fate of anthelmintics and their effects in plants has not yet been studied sufficiently. The aim of our work was to identify metabolic pathways of the two benzimidazole anthelmintics fenbendazole (FBZ) and flubendazole (FLU) in the ribwort plantain (Plantago lanceolata L.). Plants cultivated as in vitro regenerants were used for this purpose. The effects of anthelmintics and their biotransformation products on plant oxidative stress parameters were also studied...

Sepsis is a life-threatening medical condition, affecting approximately 26 million people worldwide every year. The disease is a continuum, marked by dysregulated inflammation and hemodynamic instability leading to shock, multi-system organ dysfunction, and death. Over the past decades, there has been a focus on the early identification and treatment of sepsis primarily with bundled and goal directed therapy. Despite these advances, morbidity and mortality has remained high, prompting investigation into novel therapies...

Type 1 diabetes (T1D) is the most common chronic metabolic disorder in children. Epigenetic and environmental factors capable of altering the penetrance of major susceptibility genes or capable of increasing the penetrance of low-risk genes are currently thought to play a role in triggering autoimmunity and T1D development. This paper discusses the current knowledge of the role of viruses in T1D. Most studies that have evaluated the potential association between viral infections and T1D have indicated that it is highly likely that some of these infectious agents play a role in T1D development...

The reductive detoxification of Cr(VI) by sulfite is known as the prevailing strategy and can be successfully implemented for the treatment of Cr(VI)-contaminated waters. However, this method inevitably faces the challenges of excessive consumption of sulfite due to the generations of highly oxidative OH and SO4(-) during the process of sulfite reducing Cr(VI). In this study, we find that a small quantity of thiocyanate (SCN) can catalytically enhance the process efficiency of Cr(VI) reduction by sulfite and effectively prevent the excessive consumption of sulfite...

Indigenous microorganisms in sediments could degrade polybrominated diphenyl ethers (PBDEs), but how the microbial communities respond to PBDEs was seldom reported. The effect of BDE-153, a common congener in aquatic environments, on the microbial communities in four types of aquatic sediments was evaluated during the 150days' incubation under an anaerobic condition. The intrinsic potential to remove BDE-153 varied significantly among four sediment types, and the removal rates of mangrove, mudflat, marine and freshwater sediments were 0...

A biofiltration system was developed to treat benzene, toluene, ethylbenzene, and xylene (BTEX) and Hg° vapour from a petrochemical waste stream during overhaul maintenance. The biofilter compost bed was inoculated with a microbial consortium provided by a petrochemical wastewater treatment plant. The effect of the a BTEX concentration (192.6-973.8 g/m(3)h) and empty bed residence time (EBRT) of 20-100 s were studied under the conditions of steady state, transient, shock BTEX-loading, and off-restart. The findings revealed that during a biofilter start-up, an increase in the influent BTEX concentration to around 334...

Surface modification of single-walled carbon nanotubes (SWNTs) with DNA molecules has attracted much attention in recent years to increase SWNT solubility and make various SWNT-based nanobiodevices. Therefore, there is a critical need to quantify the interaction between DNA molecules and SWNT surfaces, particularly the intermediate structures during DNA adsorption. In this study, we demonstrate the ability to detect the adsorption of DNA oligomers on SWNT surfaces by fluorescence spectroscopy. Fluorescein-labelled, 30mer, thymine oligonucleotides (F-T30) were employed as a fluorescent probe to study the interaction of DNA with SWNTs...
