Protein heterogeneity may result from many factors often closely related to the regulation of biological mechanisms. This review addresses one source of protein heterogeneity, the translation of genetic variability and transcriptional modulation to the protein level. We provide an overview how customized protein sequence databases generated using genomic and transcriptomic sequence information in conjunction with approaches to increase protein sequence coverage can aid in gaining a deeper insight into variability at the protein level. Modern approaches of DNA/RNA sequencing open the possibility to obtain detailed sequence information from individual genomes and transcriptomes at single nucleotide resolution. Further studies tried to correlate genetic variability with important biological consequences such as the risk for developing a disease or defining a personalized approach towards therapy (also called "personalized or precision medicine"). Linking genomic and transcriptomic information to complex biolog captured at the protein level. We outline a few strategies to ameliorate this situation.
The manuscript focuses on a recent trend in proteomics, namely the integration of genomic and proteomic data. Genetic and transcriptomic variability accounts for a considerable part of protein variability and is at the basis of many protein species, many of which not yet described at the protein level but many also identified as proteins or peptides with unknown function. The review highlights the challenges of current proteomics methodology, notably incomplete sequence coverage, which make it difficult to appreciate the full complexity of any proteome and leads to the fact that much variability at the DNA/RNA level is not captured at the protein level. EGFR inhibitor We outline a few strategies to ameliorate this situation.Early diagnosis and treatment of cartilage degeneration is of high clinical interest. Loss of surface integrity is considered one of the earliest and most reliable signs of degeneration, but cannot currently be evaluated objectively. Optical Coherence Tomography (OCT) is an arthroscopically available light-based non-destructive real-time imaging technology that allows imaging at micrometre resolutions to millimetre depths. As OCT-based surface evaluation standards remain to be defined, the present study investigated the diagnostic potential of 3D surface profile parameters in the comprehensive evaluation of cartilage degeneration. To this end, 45 cartilage samples of different degenerative grades were obtained from total knee replacements (2 males, 10 females; mean age 63.8 years), cut to standard size and imaged using a spectral-domain OCT device (Thorlabs, Germany). 3D OCT datasets of 8  ×  8, 4  ×  4 and 1  ×  1 mm (width  ×  length) were obtained and pre-processed (image adjustments, morphological filteriarly-degenerative cartilage, while scan area sizes considerably affected parameter values. In conclusion, cartilage surface integrity may be adequately assessed by 3D surface profile parameters, which should be used in combination for the comprehensive and thorough evaluation and overall improved diagnostic performance. OCT- and image-based surface assessment could become a valuable adjunct tool to standard arthroscopy.In this study, we have used three D-A type carbazole substituted BODIPY (carbazole connected to the meso position of BODIPY) small molecules as donors along with PC71BM as an electron acceptor for the fabrication of solution processed bulk heterojunction organic solar cells. The devices based on the as cast active layer showed power conversion efficiency in the range of 2.20-2.70%, with high open circuit voltage (Voc) in the range of 0.94-1.08 V. The high Voc is related to the deeper highest occupied molecular orbital energy level of these small molecules. The power conversion efficiency (PCE) of devices based on thermally annealed and solvent vapor annealed (TSVA) PC71BM and PC71BM processed active layers improved up to 5.05% and 4.80%, respectively, attributed to the improved light harvesting ability of active layers, better phase separation for exciton dissociation and balanced charge transport, induced by the TA and TSVA treatment.The interest for the sphenopalatine ganglion (SPG) in neurovascular headaches dates back to 1908 when Sluder presented his work on the role of the SPG in 'nasal headaches', which are now part of the trigeminal autonomic cephalalgias and cluster headache (ICHD-III-beta). Since then various interventions with blocking or lesional properties have targeted the SPG (transnasal injection of lidocaine and other agents, alcohol or steroid injections, radiofrequency lesions, or even ganglionectomy); success rates vary, but benefit is usually transient. Here we briefly review some anatomophysiological characteristics of the SPG and hypotheses about its pathophysiological role in neurovascular headaches before describing recent therapeutic results obtained with electrical stimulation of the SPG. Based on results of a prospective randomized controlled study, SPG stimulation appears to be an effective treatment option for patients with chronic cluster headaches; efficacy data indicate that acute electrical stimulation of the SPG provides significant attack pain relief and in many cases pain freedom compared to sham stimulation. Moreover, in some patients SPG stimulation has been associated with a significant and clinically meaningful reduction in cluster headache attack frequency; this preventive effect of SPG stimulation warrants further investigation. For migraine attacks, the outcome of a proof-of-concept study using a temporary electrode implanted in the pterygopalatine fossa was less encouraging; however, an ongoing multicenter trial is evaluating the efficacy of long-term SPG stimulation against sham stimulation for acute and preventive treatment in patients with frequent migraine.
This study aims to evaluate diagnosis and treatment of tethered spinal cord (TSC) in anorectal malformation (ARM) patients.

A retrospective case study was performed on patients with an ARM born between 2004 and 2011 and treated at the Erasmus MC-Sophia Children's Hospital.

During the study period, 110 neonates with ARM were treated. Spinal ultrasonography was performed in 94 (85%) patients. Ultrasonography findings were abnormal in 17 patients (18%) 16 had evidence for TSC and 1 for caudal regression. These findings were confirmed by magnetic resonance imaging (MRI) in eight patients. Six of the other 76 patients developed neurologic symptoms and MRI revealed evidence for TSC in 2 of those 6 patients. Thus, sensitivity of spinal ultrasonography was 80%, specificity was 89%, the positive predictive value was 47%, and the negative predictive value was 97%. The prevalence of TSC, as confirmed by MRI, was 9%. Three patients underwent untethering surgery one patient developed neurologic symptoms and two pati, respectively. Not in all patients an MRI was performed, but the vast majority remained clinically asymptomatic concerning TSC. Ultrasound screening seems an effective screening method, however, when ultrasonography is negative and the patient becomes symptomatic later in life, an MRI should be performed to exclude TSC. In our series, only 1 of 110 ARM patients had symptomatic tethered cord syndrome, and symptoms resolved postoperatively.
Intestinal malrotation classically presents in the neonatal period with bilious vomiting. However, population studies suggest that up to two-thirds of these patients are diagnosed later in childhood or in adulthood. Increased morbidity in the adult population has been reported. Local experience suggested that surgery was technically more difficult in older children and led to the hypothesis that it would be associated with increased morbidity.

A retrospective case note analysis was performed on all children presenting with intestinal malrotation to a tertiary referral center between January 2002 and November 2014. Case notes and operation records were reviewed and those who underwent laparotomy for confirmed malrotation were included. Children were grouped as infants (< 1 year) and older (> 1 year). The primary outcome was total emergency reoperation rate. Secondary outcomes were requirement for a bypass at reoperation and mortality.

A total of 131 children with malrotation were identified (104 in the simple Ladd procedure is deemed inadequate.
Malrotation surgery in older children is associated with a significantly higher emergency reoperation rate. The primary duodenal bypass procedure should always be considered with longstanding chronic intermittent obstruction associated with malrotation if the simple Ladd procedure is deemed inadequate.
Classically, surgical approach for palpable undescended testis (pUDT) consists is an inguinal orchidopexy. In fact, a double incision allows an adequate mobilization of the spermatic cord and an easy dissection of a patent processus vaginalis and also to perform a subdartos pouch. For reduce potential mobility of the inguinal approach, in 1989 Bianchi and Squire proposed a transcrotal orchidopexy, using a high scrotal incision. We report our experiences and retrospectively evaluate the feasibility and postoperative success of the transcrotal approach for treatment of pUDT.

From January 2012 to June 2014, 217 patients, affected by pUDT were treated at our Institution, for a total of 231 orchidopexies (203 monolateral pUDT, 14 bilateral pUDT). Patients, in whom, under anesthesia, the testis could be moved to the neck of the scrotum, have been treated with a transcrotal approach using a high scrotal incision. All patients have been clinically followed up at 1 week and at 1, 2, 3, and 6 months, at 1 year, and90% of pUDT. No major complication, such as recurrence or testicular atrophy, has been complained. Just 3 out of the 205 cases (1.5%) reported minor complications and 1 of which required a successful day-case procedure. Our data confirm that transcrotal orchidopexy can be considered effective, safe, and with a success rate being equivalent or better to classical inguinal approach.
The burden of chronic diseases in China is substantial now. Data on patterns of chronic diseases and multimorbidity among older adults, especially among those living in rural areas, are sparse.

We aim to investigate the prevalence and patterns of chronic disease pairs and multimorbidity in elderly people living in rural China.

This population-based study included 1480 adults aged 60 years and over (mean age 68.5 years, 59.4% women) living in a rural community. Data were derived from the Confucius Hometown Aging Project in Shandong, China (June 2010-July 2011). Chronic diseases were diagnosed through face-to-face interviews, clinical examinations, and laboratory tests. Patterns of chronic disease pairs and multimorbidity were explored using logistic regression and exploratory factor analyses.

The prevalence of individual chronic diseases ranged from 3.0% for tumor to 76.4% for hypertension, and each disease was often accompanied with three or more other chronic diseases. The observed prevalence of pairs of chronic conditions exceeded the expected prevalence for several conditions, such as cardiovascular diseases and metabolic disorders, as well as pulmonary diseases and degenerative disorders.
