Aim of this pilot study was to assess blood perfusion of bowel in resection lines by means of the infrared thermal imaging in order to choose the best place for anastomosis. The paper brings a first experience with infrared thermal imaging used in colorectal surgery operation from initial observation of the patient with T3 adenomatous carcinoma with no lymph node metastasis. The obtained infrared images show a clear boundary between parts of the intestine with blood perfusion and without it. The proposed position of resection of colon identified by infrared camera is in accordance with routinely designated position...

We carried out phylogenetic analyses of the relationships between Dicrocoelium chinensis populations in Japan and China using molecular markers. One hundred nine lancet flukes collected from Japan and China were identified as D. chinensis based on their testis orientation and the nucleotide sequences of their ribosomal ITS2. These flukes were analyzed phylogenetically using mitochondrial nad1 gene sequences. An analysis of molecular variance found that the percentage of variation between the countries was extremely high, indicating that the D...

Streptococcus pneumoniae (pneumococcus) is responsible for significant morbidity and mortality worldwide. It causes a variety of life-threatening infections such as pneumonia, bacteremia, and meningitis. In bacterial physiology, the metabolic pathway of branched-chain amino acids (BCAAs) plays an important role in virulence. Nonetheless, the function of IlvC, one of the enzymes involved in the biosynthesis of BCAAs, in S. pneumoniae remains unclear. Here, we demonstrated that downregulation of BCAA biosynthesis by ilvC ablation can diminish BCAA concentration and expression of pneumolysin (Ply) and LytA, and subsequently attenuate virulence...

Among 140 patients colonized by KPC-producing Klebsiella pneumoniae (KPC-Kp) between fourth and seventh day of Intensive Care Unit stay, 24 developed bacteraemia immediately after colonization. Colistin-resistance of the colonizing isolate was the factor significantly associated with early KPC-Kp bacteraemia (P < 0.001; OR 6.6, 95% CI 2.4-18.4), a worrisome finding since infections by colistin-resistant isolates is associated with increased mortality due to limited remaining therapeutic options.

INTRODUCTION: Pubic osteomyelitis is a rare type of suppurative osteomyelitis. Early diagnosis of pubic osteomyelitis is difficult, and prolonged inflammation results in progressive bone degradation, severe pelvic pain and a wide-based gait. PRESENTATION OF CASE: We report the case of an 82-year-old woman who was admitted to a previous hospital with severe abdominal pain caused by a perforated colonic diverticulum with fecal peritonitis. She underwent an emergency operation and a postoperative wound infection occurred...

This study examines the deterioration of geomaterials used throughout history that today may be found lying on the ocean floor. Submerged archaeological sites including cargoes from shipwrecks or ancient city ruins have been a topic of interest from a perspective of in situ musealization, as a way of making underwater cultural heritage accessible to the public. In an experimental study conducted at an underwater archaeological site in the Bay of Cádiz (SW Spain), we subjected two types of marble (Carrara and Macael) to three conditions to which submerged archaeological objects are often exposed: full exposure to the water column, natural processes of burial and unearthing, or permanent burial...

In this research poly(l-lysine)-b-poly(l-leucine) (PLys-b-PLeu) polymersomes were developed. It was shown that the size of nanoparticles depended on pH of self-assembly process and varied from 180 to 650nm. The biodegradation of PLys-b-PLeu nanoparticles was evaluated using in vitro polypeptide hydrolysis in two model enzymatic systems, as well as in human blood plasma. The experiments of the visualization of cellular uptake of rhodamine 6g-loaded and fluorescein-labeled nanoparticles were carried out, which approved the possibility of their penetration into the cells...

The use of molecular markers for inflammation in the gastrointestinal tract could empower optical imaging modalities for early diagnosis and eventually personalized timely treatments. A major hurdle to the widespread use of functional fluorescence imaging is the absence of suitable contrast agents, in particular to be administered via the oral route due to the usual proteolytic susceptibility of the biomarkers. By designing a retro-inverso peptide, starting from a previously described sequence specific for N-cadherin, we achieved resistance to gastrointestinal degradation and even slightly improved specificity towards the target, both in ex vivo and in vivo experimental colitis...

In plants, the presence of a seed bank challenges the application of classical metapopulation models to above-ground presence surveys; ignoring seed bank leads to overestimated extinction and colonization rates. In this article, we explore the possibility to detect seed bank using hidden Markov models in the analysis of above-ground patch occupancy surveys of an annual plant with limited dispersal. Patch occupancy data were generated by simulation under two metapopulation sizes (N = 200 and N = 1000 patches) and different metapopulation scenarios, each scenario being a combination of the presence/absence of a one-year seed bank and the presence/absence of limited dispersal in a circular 1-dimension configuration of patches...

PURPOSE OF REVIEW: The discovery of Helicobacter pylori and other organisms colonizing the stomach and the intestines has shed some light on the importance of microbiome in maintaining overall health and developing pathological conditions when alterations in biodiversity are present. The gastric acidity plays a crucial role in filtering out bacteria and preventing development of enteric infections. In this article, we discuss the physiology of gastric acid secretion and bacterial contribution to the composition of gastric and intestinal barriers and review the current literature on the role of proton pump inhibitors (PPIs) in the microbial biodiversity of the gastrointestinal tract...

Colon cancer is thought to develop in a stepwise fashion. In this study, the relationship between aberrant crypt foci (ACF) regional distribution and oxidative stress evolution was studied in a murine model of initial colon carcinogenesis induced by dimethylhydrazine (DMH). Mice were given 2 weekly subcutaneous injections of DMH (20 mg/kg) and killed at the 10th, 12th or 14th week. ACF was scored for number, distribution and crypt multiplicity after methylene-blue coloration and histologically analyzed afterwards...

The potent immunomodulatory effect of the endocrine disruptor bisphenol A during development and consequences during life span are of increasing concern. Particular interests have been raised from animal studies regarding the risk of developing food intolerance and infection. We aimed to identify immune disorders in mice triggered by perinatal exposure to bisphenol A. Gravid mice were orally exposed to bisphenol (50 μg/kg body weight/day) from day 15 of pregnancy until weaning. Gut barrier function, local and systemic immunity were assessed in adult female offspring...

Tuberous sclerosis complex (TSC) is an autosomal dominant neurocutaneous condition that predisposes to numerous proliferative lesions, including perivascular epithelioid cell tumors (PEComas), such as lymphangioleiomyomatosis (LAM) and angiomyolipomas, and rare neuroendocrine neoplasms. We describe herein a TSC2-harboring tuberous sclerosis patient manifesting with a synchronous well-differentiated L-cell rectal neuroendocrine tumor and leiomyomatosis-like LAM of the rectum. The background large bowel wall was thickened by confluent nodular areas comprising vessels and spindle-to-epithelioid cells, which are immunoreactive for myoid (smooth muscle actin, muscle specific actin, and desmin) and melanocytic markers (HMB45, Melan-A, microphthalmia transcription factor, and CD117)...

BACKGROUND: The relationship between dietary and lifestyle risk factors and long-term mortality from colorectal cancer is poorly understood. Several factors, such as obesity, intakes of red meat, and use of aspirin, have been reported to be associated with risk of colorectal cancer mortality, though these findings have not been replicated in all studies to date. METHODS: In the Minnesota Colon Cancer Control Study, 46,551 participants 50-80 years old were randomly assigned to usual care (control) or annual or biennial screening by fecal occult blood testing...
