We present a 3D time-lapse imaging method for monitoring mitochondrial dynamics in living HeLa cells based on photothermal optical coherence microscopy and using novel surface functionalization of gold nanoparticles. The biocompatible protein-based biopolymer coating contains multiple functional groups which impart better cellular uptake and mitochondria targeting efficiency. The high stability of the gold nanoparticles allows continuous imaging over an extended time up to 3000 seconds without significant cell damage...

Polyphenylene dendrimers (PPDs) represent a unique class of macromolecules based on their monodisperse and shape-persistent nature. These characteristics have enabled the synthesis of a new genre of "patched" surface dendrimers where their exterior can be functionalized with a variety of polar and unpolar substituents to yield lipophilic binding sites in a site-specific way. While such materials have proven capable of complexing biologically relevant molecules, shown high cellular uptake in various cell lines, and low to no toxicity; there is minimal understanding of the driving forces to these characteristics...

Amyotrophic Lateral Sclerosis (ALS) is an incurable motor neurodegenerative disease caused by a diversity of genetic and environmental factors leading to neuromuscular degeneration and pathophysiological implications in non-neural systems. Our previous work showed abnormal transcriptional expression levels of biomarker genes in non-neuronal cell samples from ALS patients. The same genes proved to be differentially expressed in brain, spinal cord and muscle of the SOD1(G93A) ALS mouse model. These observations support the pathophysiological relevance of the ALS biomarkers discovered in human mesenchymal stem cells (hMSC) isolated from bone marrow samples of ALS patients (ALS-hMSC)...

Repressor Activator Protein 1 (Rap1) performs multiple vital cellular functions in the budding yeast Saccharomyces cerevisiae. These include regulation of telomere length, transcriptional repression of both telomere-proximal genes and the silent mating type loci, and transcriptional activation of hundreds of mRNA-encoding genes, including the highly transcribed ribosomal protein- and glycolytic enzyme-encoding genes. Studies of the contributions of Rap1 to telomere length regulation and transcriptional repression have yielded significant mechanistic insights...

BACKGROUND: Acute kidney injury (AKI) after cardiac surgery is associated with increased morbidity and mortality. The long-term association between AKI and end-stage renal disease (ESRD) in an Asian population is unknown. Given the high prevalence of diabetes and a younger age of presentation for cardiac surgery, it is important to track this progression of kidney disease. Therefore, we studied the long-term risk of ESRD and mortality in our Asian patients who developed AKI after cardiac surgery...

BACKGROUND AND AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) is recommended for patients considered high-risk for choledocholithiasis after biochemical testing and abdominal ultrasound. Our aim was to determine whether American Society for Gastrointestinal Endoscopy (ASGE) guidelines accurately select patients where the risk of ERCP is justified. METHODS: Consecutive patients hospitalized with suspected choledocholithiasis at Sir Run Run Shaw Hospital who received biochemical testing, abdominal ultrasound, and definitive testing for choledocholithiasis (magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasound (EUS), ERCP, intraoperative cholangiogram (IOC), common bile duct (CBD) exploration) were identified...

PURPOSE: Diagnosing periprosthetic infection remains a challenge. Multiplex-PCR and biomarkers such as alpha-defensin are potentially useful and fast methods for detecting periprosthetic infection. This study compared these new methods with clinical assessment, conventional microbiological methods and histo-pathological examination. METHODS: Twenty-eight consecutive patients with 30 joints and a mean age of 67.7 years (range 39 to 88) with removal of total hip arthroplasty (THA) or total knee replacement (TKR) were included in this study...

We assessed the impact of intra- and postoperative RBC transfusion on postoperative morbidity and mortality in cranial surgery. A total of 8924 adult patients who underwent cranial surgery were identified in the 2006-2011 American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database. Patients undergoing a biopsy, radiosurgery, or outpatient surgery were excluded. Propensity scores were calculated according to demographic variables, comorbidities, and preoperative laboratory values...

Direct plantar plate repair using a plantar approach has been described previously, but with few reports of the outcomes or clinical results. The purpose of the present study was to determine the outcomes of this technique. We performed a retrospective analysis of patients who had undergone direct plantar plate repair with or without concomitant Weil osteotomy and a prospective patient-reported subjective outcomes analysis. Ultimately, 131 patients (144 toes) were included, and the response rate for the mailed surveys was 53...

PURPOSE: Radiation therapy to deep-seated targets is typically delivered with megavoltage x-ray beams generated by medical linear accelerators or (60) Co sources. Here, we used computer simulations to design and optimize a lower energy kilovoltage x-ray source generating acceptable dose distributions to a deep-seated target. METHODS: The kilovoltage arc therapy (KVAT) x-ray source was designed to treat a 4-cm diameter target located at a 10-cm depth in a 40-cm diameter homogeneous cylindrical phantom...

Danon disease is a genetic deficiency in lysosome-associated membrane protein 2 (LAMP-2), a highly glycosylated constituent of the lysosomal membrane and characterized by a cardiomyopathy, skeletal muscle myopathy, and cognitive impairment. Patients, however, often manifest hepatic abnormalities, but liver function has not been well evaluated and the syndrome is relatively uncommon. Hence, we have taken advantage of a rat that has been deleted of LAMP-2 to study the relative role of LAMP-2 on liver function...

Internet Gaming Disorder [IGD] was introduced as new behavioral addiction in DSM-5 Section 3. Vulnerability to stress is a potential predisposing factor for IGD. Given a lack of preexisting empirical data, the study investigated differences in the psychological and neurobiological response to acute stress in patients with IGD. 24 young men (mean age 18.38 years; range 13-25 years) fulfilling DSM-5 criteria for IGD and 25 matched controls underwent the Trier Social Stress Test [TSST]. Participants provided hair samples for the analysis of basal hypothalamic-pituitary-adrenal [HPA] axis activity and clinical interviews were conducted to assess psychopathology...

A redox-responsive docetaxel (DTX) prodrug consisting of a disulfide linkage between DTX and vitamin E (DTX-SS-VE) was synthesized in our laboratory and was successfully formulated into liposomes. The aim of this study was to optimize the formulation and investigate the cellular uptake of DTX prodrug-loaded liposomes (DPLs). The content of DTX-SS-VE was determined by ultra high performance liquid chromatography (UPLC). The formulation and process were optimized using entrapment efficiency (EE), drug-loading (DL), particle size and polydispersity index (PDI) as the evaluation indices...

REVIEW
J-L Besse
The causes of metatarsalgia are classified as primary, secondary, and iatrogenic. Anatomical and biomechanical considerations separate "static" from "propulsive" forms of metatarsalgia. The physical examination should be combined with an assessment of weight-bearing radiographs and, if needed, of ultrasound or magnetic resonance imaging scans. The first-line treatment is conservative (stretching exercises, footwear modification, insoles, and lesion debridement). Soft-tissue surgical procedures (gastrocnemius muscle recession, tendon transfer, and plantar plate repair) should also be considered...

Downregulation of microRNA-129 (miR-129) has been described in various types of cancer, however, the significance of miR-129 in lung cancer has not been investigated. The present study, for the first time, determined miR-129-5p expression levels in both lung cancer cell lines and primary lung cancer tissues and also studied the effect of miR-129-5p on the proliferation and invasiveness of lung cancer cells. The results showed that miR-129-5p expression was significantly reduced in both lung cancer cell lines and primary lung cancer tissues (P<0...
