BACKGROUND: Invasive fungal infections (IFI) represent a common side effect of allogeneic hematopoietic stem cell transplant (allo-SCT), resulting in increased non relapse mortality (NRM) and reduced overall survival (OS) rates. 75-days of Fluconazole 400 mg/day represents the standard primary antifungal prophylaxis (PAP) after allo-SCT, especially for low-risk transplants. However, the ideal dosage of fluconazole has never been tested. METHODS: Here we report the experience of our institution on 113 consecutive patients receiving an allo-SCT from a HLA identical sibling between 1999 and 2015, where PAP consisted of fluconazole 100 mg/day only during the pre-engraftment phase...

Short-wavelength ultraviolet (UV-C) irradiation is a nonthermal processing technique that is a possible alternative to the heat-pasteurization of tea beverages. This study investigated the effect of UV-C irradiation on the polyphenolic and total phenolic contents of a green tea beverage and analyzed cytotoxicity of irradiated green tea using a novel continuous flow-through UV system. UV-C fluence levels ranging from 0 to 240 mJ/cm2 were delivered to green tea, and polyphenols were chemically profiled. Continuous-flow UV-C irradiation of the green tea beverage at a fluence of 68 mJ/cm2  induced a minor reduction in the concentration of the most abundant catechin in green tea, (-)-epigallocatechin gallate (EGCG), from 145 to 131...

The pampas cat is a small felid that occurs in open habitats throughout much of South America. Previous studies have revealed intriguing patterns of morphological differentiation and genetic structure among its populations, as well as molecular evidence for hybridization with the closely related L. tigrinus. Here we report phylogeographic analyses encompassing most of its distribution (focusing particularly on Brazilian specimens, which had been poorly sampled in previous studies), using a novel dataset comprising 2,143 bp of the mitogenome, along with previously reported mtDNA sequences...

In our search for novel histone deacetylases inhibitors, we have designed and synthesized a series of novel hydroxamic acids and N-hydroxybenzamides incorporating quinazoline heterocycles (4a-i, 6a-i). Bioevaluation showed that these quinazoline-based hydroxamic acids and N-hydroxybenzamides were potently cytotoxic against three human cancer cell lines (SW620, colon; PC-3, prostate; NCI-H23, lung). In term of cytotoxicity, several compounds, e.g. 4g, 4c, 4g-i, 6c, and 6h, displayed from 5- up to 10-fold higher potency than SAHA (suberoylanilidehydroxamic acid, vorinostat)...

AIMS: Gastric heterotopia (GH) has been described throughout the gastrointestinal tract. However, the colorectal region is an extremely rare location for it. We describe the clinicopathologic features of GH of the colon, rectum, and anus. METHODS AND RESULTS: We identified 33 cases in 20 males and 13 females (median age 54 years; range, 4 months to 73 years). Sites included the rectum (N=26), anus (N=4), ileocecal junction (N=1), ascending colon (N=1) and descending colon (N=1)...

In this work, a new series of diethyl ((1H-indole-3-yl)((5-phenyl-1,3,4-thiadiazole-2- yl)amino)methyl)phosphonate derivatives 6(a-j) were designed and synthesized in Ultrasound by green protocol using Kabachnik-Fields reaction. The structures of the synthesized compounds were confirmed by spectral analysis such as elemental analyses, IR, 1H NMR, 13C NMR, 31P NMR and mass spectra. The synthesized compounds 6(a-j) were appraised for their in vitro anticancer activity against human cancer cell lines such as SK-MEL-2 (melanoma), IMR-32 (Neuroblastoma), HT-29(Colon) and also on normal murine embryonic fibroblast NIH/3T3 by Sulforhodamine B (SRB) assay, using Adriamycin as a standard drug...

Clostridium difficile is a major nosocomial pathogen responsible for close to half a million infections and 27,000 deaths annually in the U.S. Preceding antibiotic treatment is a major risk factor for C. difficile infection (CDI) leading to recognition that commensal microbes play a key role in resistance to CDI. Current antibiotic treatment of CDI is only partially successful due to a high rate of relapse. As a result, there is interest in understanding the effects of microbes on CDI susceptibility to support treatment of patients with probiotic microbes or entire microbial communities (e...

Reproductive phenology is an important trait subjected to natural selection. Current horses in America belong to the Palearctic original populations after being introduced by European colonizers. Photoperiod variation is the main environmental factor for the adjustment of reproductive timing in horses, but is absent in equatorial areas. Here we hypothesize that seasonality of green-grass availability may influence breeding phenology in equatorial regions. We used data of 929 services to mares from 2006 to 2011 in a thoroughbred equine exploitation in Ecuador that experienced strong grass seasonality...

The population of cancer survivors with prior cancer is rapidly growing. Whether a prior cancer diagnosis interferes with outcome is unknown. We conducted a pan-cancer analysis to determine the impact of prior cancer history for patients newly diagnosed with cancer. We identified 20 types of primary solid tumors between 2004 to 2008 in the Surveillance, Epidemiology, and End Results (SEER) database. Demographic and clinicopathologic variables were compared by chi-squared test and t-test as appropriate. The propensity score-adjusted Kaplan-Meier method and Cox proportional hazards models were used to evaluate the impact of prior cancer on overall survival (OS)...

PURPOSE: Peritoneal carcinomatosis (PC) from colorectal cancer (CRC) has poor survival. Multi-modal treatment including systemic chemotherapy, cytoreductive surgery (CRS), and hyperthermic intraperitoneal chemotherapy (HIPEC) can be used in selected patients with curative intent. The majority published works consider PC of CRC origin as a homogenous disease. Aim of this study is to stress the different biological behaviors and survival of PC according to colonic or rectal origin. METHODS: Data of CRS and HIPEC procedures for PC of CRC origin performed at MD Anderson Cancer Center-Madrid (Spain) have been collected, dividing patients into two groups according to colonic or rectal PC...

Herein, we describe the synthesis of twenty-one novel water-soluble monocationic 2-aryl/heteroaryl-substituted 6-(2-imidazolinyl)benzothiazole mesylates 3a-3u and present the results of their anti-proliferative assays. Efficient syntheses were achieved by three complementary simple two-step synthetic protocols based on the condensation reaction of aryl/heteroaryl carbaldehydes or carboxylic acid. We developed an eco-friendly synthetic protocol using glycerol as green solvent, particularly appropriate for the condensation of thermally and acid-sensitive heterocycles such as furan, benzofuran, pyrrole, and indole...

Inflammatory priming of immune cells in early life may optimize the response to a subsequent inflammatory challenge later in life. To prime the immune cells in the gut in vivo through a short inflammatory insult, we administered a low dose of dextran sulfate sodium (DSS) to 5-weeks-old BALB/c mice in the drinking water. We hypothesized that DSS-primed mice would show decreased inflammation and difference in immunological profiling, when subjected to presensitizing and oxazolone-induced colitis by rectal instillation at 9 weeks compared to non-DSS-primed control mice...

Idiopathic chronic enterocolitis (ICE) is one of the most commonly encountered and difficult to manage diseases of captive rhesus macaques ( Macaca mulatta ). The etiology is not well understood, but perturbations in gut microbial communities have been implicated. Here we evaluated the effects of a 14-day course of vancomycin, neomycin, and fluconazole on animals affected with ICE, comparing treated, untreated, and healthy animals. We performed microbiome analysis on duodenal and colonic mucosal samples and feces in order to probe bacterial and/or fungal taxa potentially associated with ICE...

We report an uncommon case of deep infiltrating endometriosis of the colon presenting as iron deficiency anemia nine years after hysterectomy with bilateral salpingo-oophorectomy. The endometrial implant was found at the hepatic flexure, an exceedingly rare location for endometriosis invasion with no cases distinctly reported in the literature. Additionally, the presentation of gastrointestinal endometriosis as iron deficiency anemia is not well documented in the literature. Instead of surgery, we prescribed a novel medical therapeutic approach using conjugated estrogen-bazedoxifene to antagonize the proliferative effects of estrogen on endometrial tissue...

Colonic duplication cysts are a rare congenital abnormality commonly presenting before two years of age. In adults, it has been rarely reported, most often as an incidental finding. We report a case of 42-year-old female complaining of constipation and lower abdominal pain. Patient's CT scan of the abdomen showed a cystic lesion at hepatic flexure and the diagnosis was confirmed endoscopically using endoscopic ultrasound (EUS). The cyst was treated employing hot snare to expose the cyst cavity. On our literature search, there have been no reported cases of colonic duplication cyst treated endoscopically...

The aging process is considered to be the result of accumulating cellular deterioration in an individual organism over time. It can be affected by the combined influence of genetic, epigenetic, and environmental factors including life-style-associated events. In the non-senescent freshwater polyp Hydra , one of the classical model systems for evolutionary developmental biology and regeneration, transcription factor FoxO modulates both stem cell proliferation and innate immunity. This provides strong support for the role of FoxO as a critical rate-of-aging regulator...

Streptococcus gallolyticus subsp. gallolyticus Sgg (formerly known as S. bovis type I) is the main causative agent of septicemia and infective endocarditis (IE) in elderly and immunocompromised persons. It belongs to the few opportunistic bacteria, which have been strongly associated to colorectal cancer (CRC). A literature survey covering a period of 40 years (1970-2010) revealed that 65% of patients diagnosed with an invasive Sgg infection had a concomitant colorectal neoplasia. Sgg is associated mainly with early adenomas and may thus constitute an early marker for CRC screening...

High mortality and hospitalization rates have seen Listeria monocytogenes as a foodborne pathogen of public health importance for many years and of particular concern for high-risk population groups. Food manufactures face an ongoing challenge in preventing the entry of L. monocytogenes into food production environments (FPEs) due to its ubiquitous nature. In addition to this, the capacity of L. monocytogenes strains to colonize FPEs can lead to repeated identification of L. monocytogenes in FPE surveillance...
