Top-down attention prioritizes the processing of goal-relevant information throughout visual cortex based on where that information is found in space and what it looks like. Whereas attentional goals often have both spatial and featural components, most research on the neural basis of attention has examined these components separately. Here we investigated how these attentional components are integrated by examining the attentional modulation of functional connectivity between visual areas with different selectivity...

Abdominal aortic aneurysms (AAAs) are a chronic vascular disease characterized by pathological luminal dilation. Aortic rupture is the fatal consequence of AAAs. Ginkgo biloba extracts (GBEs), a natural herb extract widely used as food supplements, drugs, and cosmetics, has been reported to suppress development of calcium chloride-induced AAAs in mice. Calcium chloride-induced AAAs do not rupture, while angiotensin II (AngII)-induced AAAs in mice have high rate of aortic rupture, implicating potentially different mechanisms from calcium chloride-induced AAAs...

OBJECTIVES: Our objectives were to determine whether quantitative fetal fibronectin (fFN) and cervical length (CL) screening can be used alone or in combination as prognostic tests to identify symptomatic women at highest or lowest risk for spontaneous preterm birth (sPTB). METHODS: A prospective, blinded cohort study of women presenting with a singleton gestation to our triage unit between 22-33w6d with preterm labor symptoms was performed. Women with ruptured membranes, moderate/severe bleeding, and dilation > 2 cm were excluded...

PURPOSE: Transversus abdominis plane (TAP) blockade with long-acting anesthetic can be used during open ventral hernia repair (VHR) with posterior component separation (PCS). TAP block can be performed under ultrasound guidance (US-TAP) or under direct visualization (DV-TAP). We hypothesized that US-TAP and DV-TAP provide equivalent postoperative analgesia following open VHR. METHODS: A retrospective review of patients undergoing open VHR with PCS who received TAP blocks with 266 mg of liposomal bupivacaine was performed...

BACKGROUND: Continuing professional development (CPD) for the surgeon has been challenging because of a lack of standardized approaches of hands-on courses, resulting in poor post-course outcomes. To remedy this situation, SAGES has introduced the ADOPT program, implementing a standardized, long-term mentoring program as part of its hernia hands-on course. Previous work evaluating the pilot program showed increased adoption of learned procedures as well as increased confidence of the mentored surgeons...

PURPOSE: Posterior component separation (PCS) via the transversus abdominis release (TAR) procedure continues to gain popularity. However, neither the physiologic basis nor the extent of myofascial medialization after TAR is established. We aimed to assess both anterior and posterior rectus fascia (AF and PF) medialization following each step of the TAR procedure. METHODS: Ten fresh cadavers underwent PCS via TAR. Steps included midline laparotomy (MLL), retrorectus dissection (RRD), incision of the posterior rectus sheath (IPL), transversus abdominis muscle division (TAD), and retromuscular dissection (RMD)...

Management of congenital abdominal wall malformations is still a challenge in paediatric surgery due to visceroabdominal disproportion, large defects of abdominal wall and immature abdominal cavity. Most of the patients treated with primary closure need artificial substitutes like patches or biomaterials for non-permanent abdominal wall closure. Patches represent the source of constant infections and complications like separation of prosthesis from fascia. Removal of these patches and ventral hernia repair is essential afterwards...

Over the past several years, significant efforts have been made to improve the spatial resolution of diffusion-weighted imaging (DWI), aiming at better detecting subtle lesions and more reliably resolving white-matter fiber tracts. A major concern with high-resolution DWI is the limited signal-to-noise ratio (SNR), which may significantly offset the advantages of high spatial resolution. Although the SNR of DWI data can be improved by denoising in post-processing, existing denoising procedures may potentially reduce the anatomic resolvability of high-resolution imaging data...

Claire Kruger, Yuting Zhou
On October 26, 2015, IARC published a summary of their findings regarding the association of cancer with consumption of red meat or processed meat (IARC 2015a; The Lancet Oncology 2015). The Working Group concluded that there is limited evidence in human beings for carcinogenicity from the consumption of red meat and inadequate evidence in experimental animals for the carcinogenicity of consumption of red meat. Nevertheless, the working group concluded that there is strong mechanistic evidence by which ingestion of red meat can be linked to human colorectal cancer and assigned red meat to Group 2A "probably carcinogenic to humans"...

Here we present a 32-y-old rhesus macaque (Macaca mulatta) with a large recurrent ventral incisional hernia. The initial surgery included midline celiotomy for treatment of endometriosis, in which the animal developed a hernia that was repaired with interposition of mesh. Hernia recurrence at 1 y resulted in a defect measuring 7 × 13 cm, with loss of abdominal domain. Skin breakdown was noted with areas of exposed mesh through the skin with associated acute on chronic infection. Clinically, the animal was lethargic, not eating, and failing to thrive...

Guoqiang Chen, Alisha Gerrior, Raja Ghosh
In recent papers we have discussed the optimization of design and operating conditions for cuboid packed-bed device for chromatographic separations. The efficiency metrics used in these studies included the number of theoretical plates per unit bed height as well as attributes of flow-through and eluted peaks. These studies were carried out using equivalent columns as benchmarks. The cuboid packed-bed devices consistently outperformed the columns in terms of the above metrics. The current study examines how well, or indeed if at all these superior efficiency metrics translate to superiority in multi-component protein separation...

Complex ventral hernias remain a challenge for general surgeons despite advances in minimally invasive surgical techniques. This study compares outcomes following Rives-Stoppa (RS) repair, components separation technique with mesh (CST-M) or without mesh (CST), and endoscopic components separation technique (ECST). A retrospective review of patients undergoing open ventral hernia repair between 2006 and 2011 was performed. Analysis included patient demographics, surgical site occurrences, hernia recurrence, hospital readmission, and mortality...

This paper presents a method for extracting multiple phases from a single moire fringe pattern in digital holographic interferometry. The method relies on component separation using singular value decomposition and an extended Kalman filter for demodulating the moire fringes. The Kalman filter is applied by modeling the interference field locally as a multi-component polynomial phase signal and extracting the associated multiple polynomial coefficients using the state space approach. In addition to phase, the corresponding multiple phase derivatives can be simultaneously extracted using the proposed method...

PURPOSE: This study aims to compare the outcomes of posterior component separation and transversus abdominis release (PCSTAR) with the open anterior component separation (OACS) technique. OACS, first described by Ramirez et al. (Plast Reconstr Surg 86(3):519-526, 1990), has become an established technique for local myofascial advancement in abdominal hernia surgery. PCSTAR, described by Novitsky et al. (Am J Surg 204(5):709-716, 2012), is being used more frequently and is rapidly becoming the technique of choice in complex ventral hernia repair...

The cellular structure of food tissue is complex, and it is difficult to understand the morphological changes during drying. Three different cellular environments, namely intracellular space, intercellular space, and cell wall in food tissue contain a different proportion of water. It is crucial to understand the moisture migration mechanisms from different cellular environments during drying for improving energy efficiency and for ensuring better quality dried foods. Due to the lack of sufficient understanding of transport mechanisms of different types of water, existing mathematical models for food drying have been developed without considering these components separately...
