Strains of Toxoplasma gondii in Brazil are highly genetically diverse compared to strains from North America and Europe. Dogs are epidemiologically important because they act as sentinels for T. gondii infections in humans and are good indicators of environmental contamination. The aim of this study was to isolate and genetically characterize T. gondii strains from tissues of naturally infected Brazilian dogs. For this study, 21 blood samples were collected from dogs at the Zoonosis Control Centers of Ilhéus and Itabuna cities, Bahia, Brazil...

BACKGROUND/AIMS: Diabetic nephropathy (DN) is a microangiopathic disease characterized by excessive urinary albumin excretion, which occurs in 30% of patients with diabetes mellitus. It is the second leading cause of end-stage renal diseases in China. Nuclear factor-kappa B (NF-κB) is reported to be closely correlated with the inflammation underlying diabetes-associated renal damage. Crocin, a plant-derived compound, has antioxidant properties that may inhibit NF-κB. METHODS: In the present study, we used a conditionally immortalized mouse podocyte cell line to explore whether crocin could effectively block albuminuria...

Genetic maps are based on the recombination frequency of molecular markers which often show different positions in comparison to the corresponding physical maps. To decipher the position and order of DNA sequences genetically mapped to terminal and interstitial regions of barley (Hordeum vulgare) chromosome 3H, fluorescence in situ hybridization (FISH) on mitotic metaphase chromosomes was performed with 16 genomic single-copy probes derived from fingerprinted BAC contigs. Long genetic distances at subterminal regions translated into short physical distances, confirming that recombination events occur more often at distal regions of chromosome 3H...

Preeclampsia (PE) is involved in a group of obstetrical conditions closely related by the presence of placental dysfunction (PD), which also includes intrauterine growth restriction and placental abruption. The timely and accurate recognition and management of PE are often challenging because diagnostic criteria are still based on nonspecific signs and symptoms and because common severity criteria correlate poorly with adverse maternal and fetal outcomes. The discovery of the role of angiogenesis-related factors - soluble fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) - in the underlying pathophysiology of PD has marked an important step for improving its early diagnosis and prognosis assessment before gestational week 34...

We conducted a prospective multicenter phase II trial of patients with borderline resectable pancreatic carcinoma to investigate the efficacy of neoadjuvant nab-paclitaxel plus gemcitabine therapy on overall survival (OS). The clinical trial primarily evaluated OS time from the first day of protocol therapy as a primary endpoint. The secondary endpoints were recurrence-free survival from the first day of protocol therapy, safety of the protocol therapy (adverse effect), morbidity based on the Clavien Dindo classification of more than III, response rate, preoperative/postoperative tumor marker (CA 19-9, CEA), rate of normalization, reduction rate of the maximum standardized uptake value on positron emission tomography-computed tomography (limited to institutions where positron emission tomography-computed tomography was available), chemotherapeutic effect grade based on Evans' classification, resection rate, R0 resection rate, surgical data (operative time, blood loss, transfusion, postoperative hospital day), overall morbidity rates (reoperation, rate of readmission, mortality), patient rate in postoperative adjuvant therapy (entry rate, completion rate), dose intensity, quality of life regarding fatigue and malaise assessed by the questionnaire of FACIT-F (Japanese version), and peripheral sensory neuropathy assessed by the questionnaire of the FACT/GOG-NTX subscale (version 4; Japanese version)...

More Americans are consuming diets higher in saturated fats and refined sugars than ever before, and based on increasing obesity rates, this is a growing trend among older adults as well. While high saturated fat diet (HFD) consumption has been shown to sensitize the inflammatory response to a subsequent immune challenge in young adult rats, the inflammatory effect of HFD in the already-vulnerable aging brain has not yet been assessed. Here, we explored whether short-term (3 days) consumption of HFD would serve as a neuroinflammatory trigger in aging animals, leading to cognitive deficits...

OBJECTIVE: IL-8 (interleukin 8) protein promotes inflammatory responses, even in airways. The presence of IL-8 gene variants causes altered inflammatory responses and possibly varied responses to inhaled bronchodilators (BD). Thus, this study analyzed the IL-8 variants (rs4073, rs2227306, and rs2227307) and their association with the response to BD in cystic fibrosis (CF) patients. METHODS: Analysis of IL-8 gene variants was performed by RFLP-PCR. The association between spirometry markers and the response to BD was evaluated by Mann-Whitney and Kruskal-Wallis tests...

We compared waist-to-height ratio (WHtR) with traditional anthropometric indices in healthy women aged 21 to 45 years from urban slums of Mumbai city, India. Lipid profile and inflammatory markers were measured in a subsample of 200 women, and their relationship with WHtR was examined. Mean WHtR was 0.50 ± 0.1, but a little more than half (51.9%) of the women had WHtR ≥0.50. WHtR could correctly identify centrally obese adult women, even when they were categorized as healthy or normal according to body mass index, waist circumference, waist to hip ratio, and percentage body fat...

Mucin-type O-glycosylation is initiated by the UDP-GalNAc polypeptide:N-acetylgalactosaminyltransferase (GalNAc-T) family of enzymes. Their activity results in the GalNAc α1-O-Thr/Ser structure, termed the Tn antigen, which is further decorated with additional sugars. In neoplastic cells, the Tn antigen is often overexpressed. Because O-glycosylation is controlled by the activity of GalNAc-Ts, their regulation is of great interest. Previous reports suggest that growth factors, EGF or PDGF, induce Golgi complex-to-endoplasmic reticulum (ER) relocation of both GalNAc-Ts and Tn antigen in HeLa cells, offering a mechanism for Tn antigen overexpression termed "GALA"...

Grain weight, which is controlled by quantitative trait loci (QTLs), is one of the most important determinants of rice yield. Although many QTLs for grain weight have been identified, little is known about how different alleles in different QTLs coordinate to determine grain weight. In the present study, six grain-weight-QTLs were detected in seven mapping populations (two F2, one F3, and four recombinant inbred lines) developed by crossing 'Lemont', a United States japonica variety, with 'Yangdao 4', a Chinese indica variety...

Despite the importance of recognizing neuroendocrine differentiation when diagnosing tumors of the thoracic cavity, the sensitivity of traditional neuroendocrine markers is suboptimal, particularly for high-grade neuroendocrine carcinomas such as small cell lung carcinoma and large cell neuroendocrine carcinoma. To increase sensitivity, neuroendocrine markers are routinely ordered as panels of multiple immunostains where any single positive marker is regarded as sufficient evidence of neuroendocrine differentiation...

Differential diagnosis based on morphology and immunohistochemistry between a clinically nonfunctioning pituitary neuroendocrine tumor (NET)/pituitary adenoma and a primary or secondary NET of nonpituitary origin in the sellar region may be difficult. Serotonin, a frequently expressed marker in the NETs, has not been systematically evaluated in pituitary NETs. Although mutations in ATRX or DAXX have been reported in a significant proportion of pancreatic NETs, the mutational status of ATRX and DAXX and their possible pathogenetic role in pituitary NETs are unknown...
