OBJECTIVE(S): The aim of our study is to analyse the inflammatory markers and lipid accumulation product (LAP) index in nonobese adolescents and younger aged women with polycystic ovary syndrome (PCOS) compared with age and body mass index (BMI)-matched healthy controls and to determine whether the investigated parameters are potential markers for the etiopathogenesis of PCOS. We also aim to determine whether these inflammatory markers are predictive for developing some clinical implications, such as cardiovascular disease (CVD) and insulin resistance (IR), associated with PCOS...

Neokestose has superior prebiotic effects compared with the commercial fructooligosaccharides (FOS). In addition, the branched structure of neokestose, a type of neo‑FOS, confers improved chemical stability compared with conventional FOS; therefore, the investigation of the branched structure by the present study may be of high biomedical value. The present study aimed to determine whether neokestose may suppress growth of the A2058 melanoma cell line. The cells were initially treated with neokestose; subsequently, in vitro cytotoxicity was assessed using MTT, and cell cycle progression and apoptosis were detected using flow cytometry...

Tendon injuries impose significant clinical burdens on healthcare systems worldwide. At present, no therapeutic methods can cure tendon injuries in an ideal manner. With the development and improvement of decellularization technology, tendon extracellular matrix (ECM) can develop into novel scaffolds with potential for repairing injured tendons. Proper agents and decellularization protocols were developed to obtain tendon ECMs, and the method used to recellularize the tendon ECM was explored to create bio-functional neo-tendons for transplants...

Mutationally activated Ras is one of the most common oncogenic drivers found across all malignancies, and its selective inhibition has long been a goal in both pharma and academia. One of the oldest and most validated methods to inhibit overactive Ras signaling is by interfering with its post-translational processing and subsequent cellular localization. Previous attempts to target Ras processing led to the development of farnesyltransferase inhibitors, which can inhibit H-Ras localization but not K-Ras due to its ability to bypass farnesyltransterase inhibition though alternative prenylation by geranylgeranyltransferase...

REVIEW
Danielle Collins, Heidi Chua
Historically, the 5-year survival rates for patients with stage 4 (metastatic) colorectal cancer were extremely poor (5%); however, with advances in systemic chemotherapy combined with an ability to push the boundaries of surgical resection, survival rates in the range of 25-40% can be achieved. This multimodal approach of combining neo-adjuvant strategies with surgical resection has raised a number of questions regarding the optimal management and timing of surgery. For the purpose of this review, we will focus on the treatment of stage 4 colorectal cancer with synchronous liver metastases...

Terrestrial opossums use their semi-prehensile tail for grasping nesting materials as opposed to arboreal maneuvering. We relate the development of this adaptive behavior with ontogenetic changes in myosin heavy chain (MHC) isoform expression from 21 days to adulthood. Monodelphis domestica is expected to demonstrate a progressive ability to flex the distal tail up to age 7 months, when it should exhibit routine nest construction. We hypothesize that juvenile stages (3-7 months) will be characterized by retention of the neonatal isoform (MHC-Neo), along with predominant expression of fast MHC-2X and 2B, which will transition into greater MHC-1β and 2A isoform content as development progresses...

Preoperative systemic inflammatory response is associated with a poor long-term prognosis following resection surgery for malignant tumors. Several markers of systemic inflammation have been reported to be associated with the outcome; however, they have not currently been fully investigated. Therefore, the association between preoperative peripheral blood neutrophil count and oncological outcome following hepatic resection for colorectal liver metastasis (CRLM) was retrospectively investigated. The present study comprised 89 patients who had undergone hepatic resection for CRLM between January 2000 and March 2010...

Interactions between early developing Schistosoma mansoni larval stages and the hemolymph of its snail intermediate host represent the first molecular encounter with the snail's immune system. To gain a more comprehensive understanding of this early parasite-host interaction, biotinylated sporocyst tegumental membrane (Mem) proteins and larval transformation proteins (LTP) were affixed to streptavidin-agarose beads and used as affinity matrices to enrich for larval-reactive plasma proteins from susceptible (NMRI) and resistant (BS-90) strains of the snail Biomphalaria glabrata...

INTRODUCTION: The stomach is the most common site for GISTs. Wide local resection to achieve negative margins is the standard of care. Giants GISTs requiring extensive resection are usually managed with neo-adjuvant therapy followed by partial or total gastrectomy. PRESENTATION OF CASE: We present a case report of a giant GIST on the lesser curvature of the stomach. Neo-adjuvant therapy was administered. Intra-operative endoscopy was used to reduce the extent of gastric resection...

PURPOSE OF REVIEW: Retroperitoneal sarcomas are rare tumors and with complex treatment. In this manuscript we give an overview of current standards in treatment of this disease and discuss new developments. RECENT FINDINGS: Surgery with complete resection of the primary tumor is still the only curative modality. The role of preoperative radiotherapy is not clear and is currently being investigated in a clinical trial. Neo-adjuvant chemotherapy is not the standard of care but can be considered occasionally when complete resection is uncertain...

Copper is an essential element for proper organismal development and is involved in a range of processes including oxidative phosphorylation, neuropeptide maturation, and connective tissue maturation. The copper transporter (Ctr) family of integral membrane proteins is ubiquitously found in eukaryotes and mediates the high-affinity transport of Cu+ across both the plasma membrane and endomembranes. While mammalian Ctr1 functions as a Cu+ transporter for Cu acquisition and is essential for embryonic development, a homologous protein, Ctr2, has been proposed to function as a low-affinity Cu transporter, a lysosomal Cu exporter, or a regulator of Ctr1 activity, but its functional and evolutionary relationship to Ctr1 is unclear...

REVIEW
Carmelo M Vicario, Robert D Rafal, Davide Martino, Alessio Avenanti
Disgust is a multifaceted experience that might affect several aspects of life. Here, we reviewed research on neurological and psychiatric disorders that are characterized by abnormal disgust processing to test the hypothesis of a shared neurocognitive architecture in the representation of three disgust domains: i) personal experience of 'core disgust'; ii) social disgust, i.e., motor and vocal expressions of disgust; iii) moral disgust, i.e., sensitivity to ethical violations. Our analysis provides some support to the shared neurocognitive hypothesis and suggests that the insula might be the "hub" structure linking the three domains of disgust sensitivity, while other brain regions may subserve specific facets of the multidimensional experience...
