Perforated small intestine in a patient with T-cell lymphoma; a rare cause of peritonitis

The nontraumatic perforations of the small intestine are pathological entities with particular aspects in respect to diagnosis and treatment. These peculiarities derive from the nonspecific clinical expression of the peritonitis syndrome, and from the multitude of causes that might be the primary sources of the perforation: foreign bodies, inflammatory diseases, tumors, infectious diseases, etc. Accordingly, in most cases intestinal perforation is discovered only by laparotomy and the definitive diagnosis is available only after histopathologic examination. Small bowel malignancies are rare; among them, lymphomas rank third in frequency, being mostly B-cell non Hodgkin lymphomas. Only 10% of non-Hodgkin lymphomas are with T-cell. We report the case of a 57 years’ old woman with intestinal T-cell lymphoma, whose first clinical symptomatology was related to a complication represented by perforation of the small intestine. Laparotomy performed in emergency identified an ulcerative lesion with perforation in the jejunum, which required segmental enterectomy with anastomosis. The nonspecific clinical manifestations of intestinal lymphomas make from diagnosis a difficult procedure. Due to the fact that surgery does not have a definite place in the treatment of the small intestinal lymphomas (for cases complicated with perforation), and beyond the morbidity associated with the surgery performed in emergency conditions, prognosis of these patients is finally given by the possibility to control the systemic disease through adjuvant therapy

Binary Mixture Composed of Nematic Liquid Crystal and Carbon Nanotubes: A Theoretical Description

Based on the phenomenological model first presented by van der Schoot et al., which predicts the alignment of carbon nanotube (CNT) dispersions in thermotropic nematic liquid crystals, we present the extensive results concerning the phase diagram and the orientational properties of the mixture in this chapter

Biodegradation study of some food packaging biopolymers based on PVA

Abstract Polymers are a common choice as protective materials since they combine flexibility, variable sizes and shapes, relatively light weight, stability, resistance to breaking, barrier properties and perceived high-quality image with cost-effectiveness. Currently, mainly non-biodegradable petroleum-based synthetic polymers are used as packaging materials for foods, because of their availability, low cost and functionality. However, biopolymers can be made from renewable resources without the environmental issues of petroleum-based polymers and with the additional advantage of being available from renewable sources or as by-products or waste-products from the food and agriculture industries. The aim of this study was to test some food packaging biopolymers based on PVA. In this respect, some biopolymers for food packaging applications were subjected to biodegradation tests by covering the tested samples with soil. The samples were incubated in known temperature and humidity conditions. The experiment lasted 45 days, after that the samples were washed, weighed and the biodegradation degree was calculated. The obtained results shows that PVA is a promising material for food packaging usage, as it is made from renewable resources and it is environmentally friendly.Â

Appendicular mass – a rare form of tuberculosis

Tuberculosis is in the top 10 causes of death worldwide, being one of the most deadly infectious diseases. It is estimated that one of three people from the entire earth population has a latent infection with M tuberculosis. This aerobic bacterium possesses the ability to persist in host tissues for years and to begin replication once immunity declines. The lungs are most frequent site of infection as the Mycobacterium tuberculosis is carried by aerosol droplets and is commonly transmitted by respiratory route. The second way of transmission is by contaminated food. Intestinal contamination coexists with pulmonary tuberculosis and only 10% represent primitive enteric diseases. The ileocecal region is involved most frequently. Even in this context isolated appendicular involvement remains rare. We report the case of appendicular tuberculosis in a 17-year-old woman with no evidence of other location of disease elsewhere in the body

How to run molecular dynamics simulations on electrospray droplets and gas phase proteins: Basic guidelines and selected applications.

The ability to transfer intact proteins and protein complexes into the gas phase by electrospray ionization (ESI) has opened up numerous mass spectrometry (MS)-based avenues for exploring biomolecular structure and function. However, many details regarding the ESI process and the properties of gaseous analyte ions are difficult to decipher when relying solely on experimental data. Molecular dynamics (MD) simulations can provide additional insights into the behavior of ESI droplets and protein ions. This review is geared primarily towards experimentalists who wish to adopt MD simulations as a complementary research tool. We touch on basic points such as force fields, the choice of a proper water model, GPU-acceleration, possible artifacts, as well as shortcomings of current MD models. Following this technical overview, we highlight selected applications. Simulations on aqueous droplets confirm that native ESI culminates in protein ion release via the charged residue model. MD-generated charge states and collision cross sections match experimental data. Gaseous protein ions produced by native ESI retain much of their solution structure. Moving beyond classical fixed-charge algorithms, we discuss a simple strategy that captures the mobile nature of H+ within gaseous biomolecules. These mobile proton simulations confirm the high propensity of gaseous proteins to form salt bridges, as well as the occurrence of charge migration during collision-induced unfolding and dissociation. It is hoped that this review will promote the use of MD simulations in ESI-related research. We also hope to encourage the development of improved algorithms for charged droplets and gaseous biomolecular ions
