Noncirrhotic portal hypertension (NCPH) is a well-known clinical entity, but often underdiagnosed. One of the common causes of NCPH is nodular regenerative hyperplasia (NRH) that presents as nodularity with features of portal hypertension and thus often diagnosed as cirrhosis. BIX 01294 clinical trial Although NRH has no histologic fibrosis, the liver synthetic function remains intact; thus, clinical diagnosis is essential because management may differ from cirrhosis. We were asked to consult in this series of 4 patients who had new-onset ascites after kidney transplantation and were diagnosed with NCPH from NRH. © 2019 The Author(s).

Incidence of squamous cell cancer of the esophagus is low in the United States. Combined tumors with components of both neuroendocrine and squamous cell cancer which are very rarely seen have not been reported in the United States. We present a unique case of a composite tumor of the esophagus with squamous cell carcinoma and neuroendocrine carcinoma. © 2019 The Author(s).

Since patients with hepatitis B virus (HBV) infection were excluded from pivotal trials, the risk of HBV reactivation with this novel drug class remains uncertain. We present the first case of tocilizumab-associated HBV reactivation resulting in fulminant hepatic failure and a need for liver transplant. Our findings underscore the need for prophylactic antiviral therapy in patients being treated with novel immunosuppressive agents. © 2019 The Author(s).

The clinical biomechanical investigation has become of great importance in the setting of refractive surgery to identify patients at higher risk of developing iatrogenic ectasia after laser vision correction. This review discusses the latest developments in the detection of corneal ectatic diseases. These developments should be considered in conjunction with multimodal corneal and refractive imaging, including Placido-disk based corneal topography, Scheimpflug corneal tomography, anterior segment tomography, spectral-domain optical coherence tomography (SD-OCT), very-high-frequency ultrasound (VHF-US), ocular biometry, and ocular wavefront measurements. The ocular response analyzer (ORA) and the Corvis ST are non-contact tonometry systems that provide a clinical corneal biomechanical assessment. More recently, Brillouin optical microscopy has been demonstrated to provide in vivo biomechanical measurements. The integration of tomographic and biomechanical data into artificial intelligence techniques has demonstrated the ability to increase the accuracy to detect ectatic disease and characterize the inherent susceptibility for biomechanical failure and ectasia progression, which is a severe complication after laser vision correction. © The Author(s). 2020.Fenugreek is one of the important edible and medicinal vegetables that have a long history of cultivation and consumption. Characterize the extent of the genetic diversity among landraces will provide a good context for future breeding programs and genetic resource preservation. Genetic diversity and population structure of 88 individuals of eight landraces of Iranian fenugreek evaluated based on SRAP markers. Seventy-two bands generated from 6 primers in which 56 (80.11%) band were polymorph. Hamadan landrace showed the lowest values of percentage of polymorphic loci (67.86), Nei’s gene diversity index (0.24), number of effective alleles (1.40) and Shannon’s Information index (0.36). Nei’s genetic distance matrix revealed the highest genetic distance between Hamadan and Yazd (0.203) and the highest genetic similarity between Mahallat and Varamin (0.036) landraces. The most gene flow was between Mahallat and Varamin landraces (Nm=8.36) and the least was between Shiraz and Hamadan landraces (Nm=0.66). An extent admixture of alleles between the Iranian fenugreek landraces was observed by the population structure. Mantel test indicated that the genetic differentiation and gene flow is not associated with geographic distance in Iranian fenugreek landraces. Our observations indicated SRAP is an efficient technique to reveal genetic diversity and population structure of Iranian fenugreek landrace.Skeletal muscle injuries are one of the most common problems in the worldwide which impose a substantial financial burden to the health care system. Accordingly, it widely accepted that muscle regeneration is a promising approach that can be used to treat muscle injury patients. However, the underlying mechanisms of muscle regeneration have yet to be elucidated. The muscle structure and muscle-related gene expression are highly conserved between human and zebrafish. Therefore, the zebrafish can be considered as an ideal animal model in muscle regeneration studies. In this study, Tol2 transposase was applied to produce Tg(mylpfa cfp-nfsB) zebrafish model that express a fusion protein composed of cyan fluorescent protein (CFP) and nitrorudactase (NTR) under control of mylpfa promoter. The results showed that MTZ (Metronidazole) treatment of Tg(mylpfacfp-nfsB) zebrafish larvae can lead to muscle injury by selective ablation of muscle cells. And also, results confirmed the muscle regeneration ability of the transgenic larvae after withdrawal of Mtz for three days. Overall, The results of this study suggest that the Tg(mylpfacfp-nfsB) zebrafish model can be used in muscle regeneration study in order to elucidate the mechanisms of this process.
