Pharmacotherapeutic options are limited for hepatocellular carcinoma (HCC). Recently, we identified the anti-tumor ligand MHC class I polypeptide-related sequence A (MICA) gene as a susceptibility gene for hepatitis C virus-induced HCC in a genome-wide association study (GWAS). To prove the concept of HCC immunotherapy based on the results of a GWAS, in the present study, we searched for drugs that could restore MICA expression. A screen of the FDA-approved drug library identified the anti-cancer agent vorinostat as the strongest hit, suggesting histone deacetylase inhibitors (HDACis) as potent candidates...

Human particulate dentin (HPD) shows potential as an alternative bone grafting material. However, the mechanism of bone healing at the molecular level after grafting with HPD is unclear. This study assessed the histological and global gene expression of bone tissues grafted with HPD. The HPD was prepared to 250-500 µm in size. X-ray diffraction (XRD) and energy dispersive x-ray spectroscopy (EDX) were performed to confirm the crystal structure, organic compound residues, and surface morphology, respectively...

A pulse height analyzing x-ray tomography system has been developed to detect x-rays from electron Bernstein wave heated electrons in the Madison symmetric torus reversed field pinch (RFP). Cadmium zinc telluride detectors are arranged in a parallel beam array with two orthogonal multi-chord detectors that may be used for tomography. In addition a repositionable 16 channel fan beam camera with a 55° field of view is used to augment data collected with the Hard X-ray array. The chord integrated signals identify target emission from RF heated electrons striking a limiter located 12° toroidally away from the RF injection port...

The cytogenetic analysis of plasma cell myeloma (PCM) allows stratification of patients so that prognosis may be determined and appropriate therapeutic options can be discussed. Owing to the patchy nature of the disease in the bone marrow (BM), the low proliferative activity of plasma cells and the cryptic nature of some PCM-associated cytogenetic changes, karyotypic analysis in this disease should be augmented with targeted interphase fluorescence in situ hybridization (FISH). Immunofluorescent revelation of cytoplasmic immunoglobulin light chains, together with interphase FISH (cIg-FISH), allows the identification of plasma cells within a sample so that they may be scored preferentially...

Food allergy is a harmful immune reaction driven by uncontrolled type 2 immune responses. Considerable evidence demonstrates the key roles of mast cells, IgE, and TH2 cytokines in mediating food allergy. However, this evidence provides limited insight into why only some, rather than all, food allergic individuals are prone to develop life-threatening anaphylaxis. Clinical observations suggest that patients sensitized to food through the skin early in life may later develop severe food allergies. Aberrant epidermal thymic stromal lymphopoietin and interleukin (IL) 33 production and genetic predisposition can initiate an allergic immune response mediated by dendritic cells and CD4(+)TH2 cells in inflamed skin...

The enzyme under lower-intensity ultrasonic irradiation leads to favourable conformational changes, thereby enhancing its activity. The augmentation of activity of ultrasound-treated enzyme is strongly dependent on ultrasound intensity, duty cycle and exposure time, which was investigated for commercial lipases. Thermomyces lanuginosus (TL) lipase showed a 1.3-fold enhanced activity after irradiating at 22 kHz and 11.38 W cm(-2) with 50 % duty cycle for 25-min ultrasonic treatment and 1.5-fold enhanced activity was observed for lipozyme (candida antarctica lipase B (CALB)) lipase, at 22 kHz and 15...

Tendon transfer options to reconstruct a massive irreparable posterior-superior rotator cuff tear include latissimus dorsi, teres major, or lower trapezius transfer. We previously described the lower trapezius transfer using a 2-incision approach, which includes a medial incision to harvest the lower trapezius and lateral transacromial incision to expose the rotator cuff and then perform the transfer through a deep tunnel connecting these 2 sites. In this report, we describe an arthroscopic-assisted technique of lower trapezius transfer augmented with an Achilles tendon allograft to reconstruct an irreparable posterior-superior rotator cuff tear...

Negative pressure wound therapy (NPWT) is widely used to treat many types of complex wounds, and the advent of the instillation and dwell time (NPWTi-d) technique has enhanced this system with the addition of automated treatment with topical solutions. In the field of vascular surgery, NPWT is utilized to help close wounds over underlying grafts; however keeping these wounds free of infection and avoiding large reoperation when infection occurs remains a challenge. In this case report we present a patient who required acute intervention for limb ischemia, with a large wound created in the groin for anastomosis of a prosthetic graft bypass...

Petras Stirbys Md PhD
The underlying pathophysiology of supraventricular and ventricular arrhythmias remains a matter of intense investigation. Though evolving, the contemporary explanations do not encompass all aspects of arrhythmogenicity. An improved understanding of arrhythmia substrate is needed to augment therapeutic capabilities. Our observation and literature sources demonstrate relatively high incidence of transitory arrhythmias which are non-intentionally generated by the endocardial lead/catheter manipulation. These findings are interesting and potentially may crystallize the reflex-dependent proarrhythmic cardiac activity...

Collateral circulation is a key variable determining prognosis and response to recanalization therapy during acute ischemic stroke. Remote ischemic perconditioning (RIPerC) involves inducing peripheral ischemia (typically in the limbs) during stroke and may reduce perfusion deficits and brain damage due to cerebral ischemia. In this study, we directly investigated pial collateral flow augmentation due to RIPerC during distal middle cerebral artery occlusion (MCAo) in rats. Blood flow through pial collaterals between the anterior cerebral artery (ACA) and the MCA was assessed in male Sprague Dawley rats using in vivo laser speckle contrast imaging (LSCI) and two photon laser scanning microscopy (TPLSM) during distal MCAo...

Distinct populations of D1- and D2-dopamine receptor expressing medium spiny neurons (D1-/D2-MSNs) comprise the nucleus accumbens, and activity in D1-MSNs promotes, while activity in D2-MSNs inhibits motivated behaviors. We used chemogenetics to extend D1-/D2-MSN cell specific regulation to cue-reinstated cocaine seeking in a mouse model of self-administration and relapse, and found that either increasing activity in D1-MSNs or decreasing activity in D2-MSNs augmented cue-induced reinstatement. Both D1- and D2-MSNs provide substantial GABAergic innervation to the ventral pallidum, and chemogenetic inhibition of ventral pallidal neurons blocked the augmented reinstatement elicited by chemogenetic regulation of either D1- or D2-MSNs...

Altered synaptic bioactive lipid signaling has been recently shown to augment neuronal excitation in the hippocampus of adult animals by activation of presynaptic LPA2-receptors leading to increased presynaptic glutamate release. Here, we show that this results in higher postsynaptic Ca(2+) levels and in premature onset of spontaneous neuronal activity in the developing entorhinal cortex. Interestingly, increased synchronized neuronal activity led to reduced axon growth velocity of entorhinal neurons which project via the perforant path to the hippocampus...

Depression is a devastating disorder which has a high impact on the wellbeing of overall society. As such, need for innovative therapeutic agents are always there. Most of the researchers focused on N-methyl-d-aspartate receptor to explore the antidepressant like activity of new therapeutic agents. Dextromethorphan is a cough suppressant agent with potential antidepressant activity reported in mouse force swimming test. Considering N-methyl-d-aspartate as a forefront in exploring antidepressant agents, here we focused to unpin the antidepressant mechanism of dextromethorphan targeting N-methyl-d-aspartate receptor induced nitric oxide-cyclic guanosine monophosphate signaling...

Biogas or biomethane is traditionally produced via anaerobic digestion, or recently by thermochemical or a combination of thermochemical and biological processes via syngas (CO and H2) fermentation. However, many of the feedstocks have recalcitrant structure and are difficult to digest (e.g., lignocelluloses or keratins), or they have toxic compounds (such as fruit flavors or high ammonia content), or not digestible at all (e.g., plastics). To overcome these challenges, innovative strategies for enhanced and economically favorable biogas production were proposed in this review...

The purpose of this article is to describe reconstruction of the maxillary alveolar ridge by use of a microvascular free flap combined with an immediate tissue-engineered bone graft. This novel surgical technique involved the use of a radial forearm free flap and immediate allogeneic avascular bone graft augmented with bone morphogenetic protein and bone marrow aspirate concentrate. A poly-d,l-lactic acid mesh was used a containment unit for the bone graft. The patient was successfully treated with a viable radial forearm free flap for soft tissue and regeneration of bone with adequate height and width, which allowed the placement of 3 dental implants with excellent arch coordination...

REVIEW
Mya E Levy, Sean P Elliott
The gold standard for bulbar urethroplasty has been excision and primary anastomosis. Application of this approach is generally limited to strictures that are 2 cm or less in the bulbar urethra due to penile shortening. Strictures greater than 2 cm are successfully treated with augmentation urethroplasty wherein the narrowed segment is not excised but widened with the use of a skin flap or a tissue graft. Buccal mucosa is the most prevalent tissue for bulbar urethral stricture repair for strictures greater than 2 cm...

REVIEW
Brendan Michael Browne, Alex J Vanni
The current management for complex urethral strictures commonly uses open reconstruction with buccal mucosa urethroplasty. However, there are multiple situations whereby buccal mucosa is inadequate (eg, pan-urethral stricture or prior buccal harvest) or inappropriate for utilization (eg, heavy tobacco use or oral radiation). Multiple options exist for use as alternatives or adjuncts to buccal mucosa in complex urethral strictures. This article reviews the current state of alternate techniques for urethral stricture treatment besides buccal mucosa, including injectable antifibrotic agents, augmentation urethroplasty with skin flaps, lingual mucosa, colonic mucosa, and new developments in tissue engineering for urethral graft material...
