Authors: Yu HX, Han CS, Xue JR, Han ZF, Xin H Abstract INTRODUCTION: Esophageal hiatal hernia involves abnormal abdominal entry into thoracic cavity. It is classified based on orientation between esophageal junction and diaphragm. Sliding hiatal hernia (Type-I) comprises the most frequent category, emanating from right crus of diaphragm. Type-II esophageal hernia engages both left and right muscular crura. Type-III and IV additionally include the left crus. Age and increased body mass index are key risk factors, and congenital skeletal aberrations trigger pathogenesis through intestinal malrotations. Familiar manif...

A patient sent me this emailI had a query. I have conceived through IVF and ET was on Jan 6 th and my LMP was on Dec 20th.I got my ultrasound done on 16th Feb and in scan it showed the pregnancy is 5 weeks 6 days.If I calculate the growth of the baby from the date of the transfer, this seems fine, but if I calculate from the date of the LMP , it seems to be lagging behind.I am completely confused - can you please help ?This is a common problem, because IVF patients use their common sense and assume that doctors would calculate pregnancy dates based on the age of the embryo. Since they know the date of the embryo transfer, ...

We report an unusual case of large Brunner's gland hyperplasia in 72-years old man, admitted to hospital for epigastric pain, recurrent vomiting and significantly weight loss. Upper endoscopy showed an obstructive submucosis tumour of the bulb. Abdominal computed tomography scan revealed a circumferential thickening and stenosing mass of the first part of the duodenum leading to severe obstruction. Though pre-operative biopsies were negative, imaging studies and endoscopy were strongly suggestive of malignancy and the patient underwent duodenocephalopancreatectomy. Brunner's gland hyperplasia may have unusual presentation,...

We report an ALK-rearranged adenocarcinoma of the lung presenting as a pituitary metastasis, clinically simulating a pituitary adenoma. The patient, a 50 year-old, former-smoking woman was admitted with a Parinaud's syndrome characterized by progressive oculomotor impairment of visual verticality, bitemporal hemianopsia and nystagmus. Imaging studies showed a sellar tumor and the biopsy revealed a TTF-1 and napsin positive lung adenocarcinoma strongly expressing synaptophysin and CD56, also harboring ALK rearrangement. A subsequent CT scan disclosed the primary lung mass of the left upper lobe. The patient progressed after...

AbstractAn index case of Legionnaires ’s disease with mediastinal adenopathy prompted us to review our recent experience with Legionnaires’ disease to determine the incidence of mediastinal adenopathy of this finding in Legionnaires’ disease. We reviewed the radiographic findings of 90 hospitalized adults with Legionnaires’ dise ase from 2015 to 2017. Excluded were 11 patients with mediastinal adenopathy due to non-Legionnaires’ disease causes, e.g., lymphoma. Thirty-seven of the remaining patients had both chest films and chest computed tomography (CT) scans. Of the 37 Legionnaires’ dis...

Publication date: Available online 17 February 2018 Source:Microbial Pathogenesis Author(s): Xin Li, Jiajia He, Weizhe Fu, Pingping Cao, Siyi Zhang, Tao Jiang Mycobacterium tuberculosis Rv3717 has been identified as a zinc-dependent amidase which can hydrolyze peptidoglycan (PG). To demonstrate the relationship of Rv3717 and cell division, in this study, Rv3717 gene was first amplified and expressed and the resulting protein was purified by using a His-tagged approach. M. smegmatis mc2155, a fast-growing and nonpathogenic mycobacterium was used to evaluate the effect of Rv3717 on cell division. Scan electron microscope (S...

Conclusion We induced trimolters by anti-juvenile hormones and the resulting cocoons were more closely packed and had smaller silk fiber diameters. We found that the conformation of trimolters silk fibroin had a higher content of β-sheet structures and better mechanical properties. General significance Our study revealed the structures and mechanical properties of trimolter silk, and provided a valuable reference to improve silk quality by influencing molting in silkworms.

Ganiyu, Oki Muraza, Khalid Alhooshani Ceria thin film in capillary microreactor was developed as a catalyst support for palladium nanoparticles (Pd NPs) by sol–gel approach. The thickness of Pd/CeO2 film deposited in capillary of 250μm internal diameter is 200nm as measured by scanning electron microscope (SEM), and the particle size of Pd NPs as determined by the transmission electron microscope (TEM) images is 4.2nm. The Pd/CeO2 immobilized capillary was tested for hydrogenation of ph...

In this study, a high spatial resolution multispectral sensor, the High-Precision Telescope (HPT), was developed for the RISING-2 microsatellite. The HPT has four image sensors: three in the visible region of the spectrum used for the composition of true color images, and a fourth in the near-infrared region, which employs liquid crystal tunable filter (LCTF) technology for wavelength scanning. Band-to-band image registration methods have also been developed for the HPT and implemented in the image processing procedure. The processed images were compared with other satellite images, and proven to be useful in various remot...

The structure and morphology of the DA-ALG CPs were characterized by infrared spectroscopy, Zeta PALS and scanning electron microscope. The prepared DA-ALG CPs were then used as particulate emulsifier...
