Parasites as biological tags of marine, freshwater and anadromous fishes in North America from the tropics to the Arctic

SUMMARY Parasites have been considered as natural biological tags of marine fish populations in North America for almost 75 years. In the Northwest Atlantic, the most studied species include Atlantic cod (Gadus morhua), Atlantic herring (Clupea harengus) and the redfishes (Sebastes spp.). In the North Pacific, research has centred primarily on salmonids (Oncorhynchus spp.). However, parasites have been applied as tags for numerous other pelagic and demersal species on both the Atlantic and Pacific coasts. Relatively few studies have been undertaken in the Arctic, and these were designed to discriminate anadromous and resident salmonids (Salvelinus spp.). Although rarely applied in fresh waters, parasites have been used to delineate certain fish stocks within the Great Lakes-St Lawrence River basin. Anisakid nematodes and the copepod Sphyrion lumpi frequently prove useful indicators in the Northwest Atlantic, while myxozoan parasites prove very effective on the coast and open seas of the Pacific Ocean. Relative differences in the ability of parasites to discriminate between fish stocks on the Pacific and Atlantic coasts may be due to oceanographic and bathymetric differences between regions. Molecular techniques used to differentiate populations and species of parasites show promise in future applications in the field.
Matrix Metalloproteinase 20 Co-expression With Dentin Sialophosphoprotein in Human and Monkey Kidneys

We recently reported the expression of matrix metalloproteinase 20 (MMP20), hitherto thought to be tooth specific, in the metabolically active ductal epithelial cells of human salivary glands. Furthermore, our report indicated that MMP20 co-expressed and potentially interacts with dentin sialophosphoprotein (DSPP), a member of the small integrin-binding ligand N-linked glycoproteins (SIBLINGs). Our earlier reports have shown the co-expression of three MMPs, MMP2, MMP3, and MMP9, with specific members of the SIBLING family: bone sialoprotein, osteopontin, and dentin matrix protein 1, respectively. This study investigated the expression of MMP20 and verified its co-expression with DSPP in human and monkey kidney sections and human mixed renal cells by IHC, in situ proximity ligation assay, and immunofluorescence. Our results show that MMP20 is expressed in all segments of the human and monkey nephron with marked intensity in the proximal and distal tubules, and was absent in the glomeruli. Furthermore, MMP20 co-expressed with DSPP in the proximal, distal, and collecting tubules, and in mixed renal cells. Consistent with other SIBLING–MMP pairs, the DSPP–MMP20 pair may play a role in the normal turnover of cell surface proteins and/or repair of pericellular matrix proteins of the basement membranes in the metabolically active duct epithelial system of the nephrons.
Prenatal Parental Education From the Perspective of Fathers With Experience as Primary Caregiver Immediately Following Birth: A Phenomenographic Study

The aim of this phenomenographic study was to capture fathers’ conceptions of parental education topics, illuminated by their experiences as primary caregiver of their child immediately following birth. Fifteen fathers were interviewed between 8 days and 6 weeks after the birth of their child. Three categories, five subcategories, and 12 qualitatively different conceptions emerged from the study’s findings. The first category showed that parental education emphasizes the importance of normal birth. The second category illustrated that parental education defuses the issue of complicated births. The third category demonstrated that parental education preserves traditional gender roles. The study’s results may facilitate efforts to integrate fathers into parental education toward the aim of achieving parity between mother and father in their role as parents.
Mechanisms of neonatal increase in glomerular filtration rate.

To investigate the mechanisms responsible for the neonatal increase in glomerular filtration rate (GFR), renal function studies (whole kidney and micropuncture) were carried out in anesthesized fetal sheep (133-140 days gestation; term = 150 days) and lambs (12-18 days). Fetuses were delivered and placed in a water bath (39.5 degrees C), keeping the umbilical cord moist and intact. Lambs were studied on a thermostatically controlled heating pad. Animals were prepared for either blood flow studies or micropuncture measurements. Expected differences in blood composition and cardiovascular and renal function were observed between fetuses and lambs, and values obtained for most variables were similar to those measured in chronically catheterized unanesthetized animals. Fetal GFR was much lower than that of lambs (0.20 vs. 0.62 ml.min(-1). g kidney(-1), P < 0.001). Free-flow, stop-flow, and net filtration pressures (NFP) were lower in the fetuses than the lambs (NFP 20.8 vs. 23.8 mmHg, P < 0.001), as was the calculated ultrafiltration coefficient (0.014 vs. 0.022 ml.min(-1). g(-1). mmHg(-1), P < 0.001). Thus, we conclude that rises in both net filtration pressure and the ultrafiltration coefficient contribute to the large increase in GFR between fetal life and approximately 2 wk after birth.
Spatial Genetic Structure of a Vector-Borne Generalist Pathogen

ABSTRACT Vector-borne generalist pathogens colonize several reservoir species and are usually dependent on polyphagous arthropods for dispersal; however, their spatial genetic structure is generally poorly understood. Using fast-evolving genetic markers (20 simple sequence repeat loci, resulting in a total of 119 alleles), we studied the genetic structure of the vector-borne plant-pathogenic bacterium Xylella fastidiosa in Napa Valley, CA, where it causes Pierce's disease when it is transmitted to grapevines from reservoir plants in adjacent riparian vegetation. Eighty-three different X. fastidiosa multilocus microsatellite genotypes were found in 93 isolates obtained from five vineyards, resulting in an index of clonal fraction closer to 0 and a Simpson's genotypic diversity index (D) closer to a maximum value of 1. Moderate values of Nei's gene diversity (H Nei; average H Nei = 0.41) were observed for most of the X. fastidiosa populations. The low Wright's index of genetic diversity among populations calculated by the FSTAT software (Wright's F ST index) among population pairs (0.0096 to 0.1080) indicated a weak or absent genetic structure among the five populations; a panmictic population was inferred by Bayesian analyses (with the STRUCTURE and BAPS programs). Furthermore, a Mantel test showed no significant genetic isolation by distance when both Nei (r = −0.3459, P = 0.268) and linearized θ (r = −0.3106, P = 0.269) indices were used. These results suggest that the riparian vegetation from which vectors acquire the pathogen prior to inoculation of grapevines supports a diverse population of X. fastidiosa.
Prevalence of obstructive sleep apnea in surgical patients presenting to a tertiary care teaching hospital in India: A preliminary study

Background: Obstructive sleep apnea (OSA) is often not diagnosed in patients presenting for surgical procedures thereby increasing the incidence of adverse perioperative course. Early diagnosis of this disease is important in modifying anesthetic management as well as utilizing specific means which may decrease the complications and improve the patient outcome. Methods: Patients greater than eighteen years of age, ASA I-III scheduled for elective surgical procedures under anesthesia were randomly selected. Their demographic data, diagnosis and nature of surgery were noted in a semi-structured performa. They were then screened for the presence of OSA with the help of a STOP BANG questionnaire. Results: This study included two hundred four patients randomly selected. Slight female predominance was seen in this sample (55.4%). Mean age of the subjects was 42.7 years (SD=15.08). 24.5% subjects were at high risk for OSA (STOP-BANG>3) with a male predominance (72% versus 37% in low risk group; X2=18.62; P<0.001). High risk OSA subjects had higher prevalence of cardiovascular risk factors (57% vs. 11.7% in low risk group; X2=33.35; P<0.001). Similarly, this group had a higher prevalence of asthma and chronic obstructive pulmonary disease (COPD) (14% versus 3.8% in low risk group; X2=6.54; P=0.03). Prevalence of diabetes mellitus (22%) and hypothyroidism (6%) was also higher in this group (5.2% and 1.9% in low risk group respectively; X2=15.42; P<0.001). Conclusion: High degree of suspicion and knowledge of association of OSA and medical diseases may help in detection of such cases and decrease the rate of perioperative complications thus improving patients safety.
An investigation of the effects of subthalamic nucleus stimulation on acoustic measures of voice

Seven patients with Parkinson's disease were implanted with deep brain stimulators to provide chronic electrical stimulation to the subthalamic nucleus bilaterally. Acoustic recordings and neurologic assessments were undertaken before surgery in the medication‐off and medication‐on conditions and after surgery with and without electrical stimulation in the medication‐off and medication‐on conditions. The data showed significant improvements in limb motor performance in response to medication before surgery and when the subthalamic nucleus was stimulated after surgery. Six months after surgery, there were small but statistically significant increases in sound pressure level and fundamental frequency variability in response to stimulation in the medication‐on condition. No other statistically significant speech changes were measured. These findings are consistent with several other studies that have reported disparity between limb and speech improvements after neurosurgical intervention for Parkinson's disease.
MiR-143-5p Deficiency Triggers EMT and Metastasis by Targeting HIF-1α in Gallbladder Cancer

Background/Aims: Early metastasis plays a pivotal role in tumor-caused death in gallbladder cancer (GBC) patients. Increasing evidence suggest that miR-143-5p is an active player involved in cancer metastasis and a potential therapeutic target. However, its role in the development of GBC cells remains unclear. The aim of this study is to reveal the inhibiting effects of miR-143-5p on the proliferation and metastasis in GBC. Methods: Quantitative real-time PCR were used to investigate miR-143-5p and its target HIF-1α mRNA levels. Protein expression was measured by immunohistochemistry and western blot. The function and regulation mechanism of miR-143-5p was confirmed by MTS, colony formation, wound healing, transwell, and luciferase reporter assays. Results: miR-143-5p was first found significantly reduced in GBC tissues compared with corresponding noncancerous gallbladder tissues. In addition, miR-143-5p deficiency correlated well with larger tumor size, advanced TNM stage, and poorer survival rate. In vitro, miR-143-5p addition dramatically suppressed GBC cells proliferation, migration and invasion, whereas miR-143-5p antisense led the opposite effects. Further elucidating the molecular mechanism inside, we found miR-143-5p exerted its inhibitory function through downregulating the expression of HIF-1α, which further reduced Twist1 and impeded epithelial-mesenchymal transition (EMT). Conclusions: Altogether, our studies identified a novel regulator, miR-143-5p, implicated in GBC prognosis through targeting HIF-1α/EMT related signaling pathway, which could serve as a biomarker and therapeutic target for GBC.
Degrees of irreducible modular characters of blocks with cyclic defect groups

The theorem is already known for d~a — 1. We prove the theorem here by considering the tree associated with the block B. Brauer [ l ] describes this tree in discussing blocks with d = l. Dade [2] generalizes Brauer's results to arbitrary d, and his results enable us to associate the same kind of tree with the block B. The tree turns out to have a certain number e (defined below) of edges. The question of whether or not every tree with e edges is associated with some block of a group remains open. We now describe the tree (for details see Dade [2]). Let Co be the centralizer and No the normalizer of D in G. Let &0 be some block of Go such that b®~By and let E be the subgroup of No fixing bo under conjugation. Denote by e the index (E: Co). Then e divides p — 1. The irreducible characters of B can be divided into e+1 classes, of which e classes consist of one nonexceptional character each, and one class consists of the exceptional characters. (If there are no exceptional characters, then e~p--~ 1 = p — 1 , and there are e + 1 nonexceptional characters. In this case we choose one of them and treat it below as the exceptional class.) There are exactly e irreducible modular characters of B, and each one occurs as a constituent of just those irreducible characters in exactly two of the classes. We can represent this information with a graph. Let the vertices of the graph correspond to the classes of irreducible characters of B,
Survival Analysis and Prognostic Factors for Colorectal Cancer Patients in Malaysia.

BACKGROUND Cancer survival analysis is an essential indicator for effective early detection and improvements in cancer treatment. This study was undertaken to document colorectal cancer survival and associated prognostic factors in Malaysians. MATERIALS AND METHODS All data were retrieved from the National Cancer Patient Registry Colorectal Cancer. Only cases with confirmed diagnosis through histology between the year 2008 and 2009 were included. Retrieved data include sociodemographic information, pathological features and treatment received. Survival curves were plotted using the KaplanMeier method. Univariate analysis of all variables was then made using the Logrank test. All significant factors that influenced survival of patients were further analysed in a multivariate analysis using Cox' regression. RESULTS Total of 1,214 patients were included in the study. The overall 3 and 5year survival rates were 59.1% and 48.7%, respectively. Patients with localized tumours had better prognosis compared to those with advanced stage cancer. In univariate analysis, staging at diagnosis (p<0.001), primary tumour size (p<0.001), involvement of lymph nodes (p<0.001) and treatment modalities (p=0.001) were found to be predictors of survival. None of the sociodemographic characteristics were found to exert any influence. In Cox regression analysis, staging at diagnosis (p<0.001), primary tumour size (p<0.001), involvement of lymph nodes (p<0.001) and treatment modalities (p<0.001) were determined as independent prognostic factors of survival after adjusted for age, gender and ethnicity. CONCLUSIONS The overall survival rate for colorectal cancer patients in Malaysia is similar to those in other Asian countries, with staging at diagnosis, primary tumor size, involvement of lymph node and treatment modalities having significant effects. More efforts are needed to improve national survival rates in future.
Assessment of Smartphone Addiction in Indian Adolescents: A Mixed Method Study by Systematic-review and Meta-analysis Approach

There is a considerable debate on addiction and abuse to Smartphone among adolescents and its consequent impact on their health; not only in a global context, but also specifically in the Indian population; considering that Smartphone's, globally occupy more than 50% of mobile phones market and more precise quantification of the associated problems is important to facilitate understanding in this field. As per PRISMA (2009) guidelines, extensive search of various studies in any form from a global scale to the more narrow Indian context using two key search words: “Smartphone's addiction” and “Indian adolescents” was done using websites of EMBASE, MEDLINE, PubMed, Global Health, Psyc-INFO, Biomed-Central, Web of Science, Cochrane Library, world library - World-Cat, Indian libraries such as National Medical Library of India from 1 January, 1995 to March 31, 2014 first for systematic-review. Finally, meta-analysis on only Indian studies was done using Med-Calc online software capable of doing meta-analysis of proportions. A total of 45 articles were considered in systematic-review from whole world; later on 6 studies out of these 45 related to Smartphone's addiction in India were extracted to perform meta-analysis, in which total 1304 participants (range: 165-335) were enrolled. The smartphone addiction magnitude in India ranged from 39% to 44% as per fixed effects calculated (P < 0.0001). Smartphone addiction among Indian teens can not only damage interpersonal skills, but also it can lead to significant negative health risks and harmful psychological effects on Indian adolescents.
Carbon tetrachloride-induced lipid peroxidation and hyperglycemia in rat

Launaea procumbens methanol extract (LPME) was evaluated against carbon tetrachloride (CCl4)-induced pancreatic oxidative damage and hyperglycemia in rats. Various doses of the extract were administered to rats after 48 h of CCl4 treatment (3 ml/kg bodyweight (bw); intraperitoneally, 20% CCl4/olive oil) twice a week for 4 weeks. Coadministration of various concentrations of LPME (100, 150 and 200 mg/kg) ameliorated the toxicity of CCl4 and reversed the serum level of enzymes (amylase and lipase), glucose and hormone (insulin). The extract was able to reduce thiobarbituric acid reactive substance but increased the glutathione contents in pancreatic tissue. Depletion of antioxidant enzyme activities (catalase, peroxidase, superoxide dismutase, glutathione peroxidase, glutathione-S-transferase and glutathione-S-reductase) and DNA damages induced with CCl4 were restored by LPME supplement. It is suggested that LPME effectively protects the liver against the CCl4-induced oxidative damage in rats, possibly through antioxidant and/or free radical scavenging effects of flavonoids and phenolic compounds in the extract.
[MR detection of local prostate cancer recurrence after transrectal high-intensity focused US treatment: preliminary results].

PURPOSE To assess T2W and dynamic: contrast-enhanced (DCE) MR imaging in the detection of local tumor recurrence after transrectal high-intensity focused US (HIFU) treatment. MATERIALS AND METHODS Fifteen patients treated by HIFU for prostate cancer were referred for MR due to biological evidence of tumor recurrence. Axial, sagittal and coronal T2W images and DCE images (12 3-mm thick axial images, temporal resolution: 15 seconds) were obtained first. Transrectal biopsies were then obtained under US guidance. MR findings were compared to biopsy results for 10 prostate sectors. RESULTS Biopsies demonstrated tumor recurrence in 13/15 patients (23/108 sectors). On T2W images, the treated prostate tissue was diffusely hypointense which interfered with interpretation. Three patients (5 sectors) had suspicious areas of T2W signal abnormality and 15 patients (29 sectors) had suspicious areas on DCE scans. An analysis per sector for T2W and DCE imaging showed sensitivity, specificity, positive predictive and negative predictive values respectively of 0.13, 0.98, 0.6 and 0.81 and 0.70, 0.85, 0.55 and 0.91. DCE MR was strongly predictive of positive biopsy results (Odds ratio: 12.8 (95% confidence interval: 4.4-37.3)) whereas T2W imaging was not (Odds ratio: 4.0 (95% confidence interval: 0.5-30)). CONCLUSION MR, especially DCE MR, is promising for the detection and localization of local prostate cancer recurrence after transrectal HIFU treatment.
Religion: a sociocultural predictor of health behaviors in Mexico.

OBJECTIVE Tobacco, alcohol, and physical inactivity are now among the top 10 risk factors for mortality in the Americas region. Subsequently, a more complete understanding of the various cultural factors that influence health behaviors such as these is needed. METHOD This study investigates how religion influences the use of alcohol and cigarettes within a large, nationally representative sample of older adults in Mexico (Mexican Health and Aging Study, N = 10,399). RESULTS Religious salience and participation in religious activities are both significantly associated with smoking status, but not alcohol use. DISCUSSION This is one of the first studies to examine these associations in a developing country. Despite cultural differences, the negative relationship between religion and smoking in Mexico corresponds to associations seen in the United States and other Western countries. This type of information may be useful to health researchers, providers, and policy makers attempting to reduce deaths due to preventable causes.
Circuit Model for Driving Three-Dimensional Resistive MHD Wire Array $Z$ -Pinch Calculations

Compact tungsten wire array Z-pinches imploded on the Z generator at Sandia National Laboratories have proven to be a powerful reproducible X-ray source. Wire arrays have also been used in dynamic hohlraum radiation flow experiments and as an intense K-shell source, while the generator has been used extensively for isentropic compression experiments. A problem shared by all these applications is current loss, preventing the ~20-MA drive current from being reliably coupled to the load. This potentially degrades performance, while uncertainties in how this loss is described limit our predictive capability. We present details of a transmission line equivalent circuit model of the Z generator for use in driving 3-D resistive MHD simulations of wire array loads. We describe how power delivery to these loads is affected by multiple current losses and demonstrate how these may be calculated or reconstructed from available electrical data for inclusion in the circuit model. We then demonstrate how the circuit model and MHD load calculation may be combined to infer an additional current loss that has not been directly diagnosed for wire arrays.
The Impact of Endometrial Thickness on the Day of Human Chorionic Gonadotrophin (hCG) Administration on Ongoing Pregnancy Rate in Patients with Different Ovarian Response

In order to explore the impact of endometrial thickness on hCG administration day on ongoing pregnancy rate (OPR) in IVF-ET cycles, we retrospectively analyzed data from 10,406 patients undergoing their first IVF cycles with standard gonadotropin releasing hormone analogue (GnRH-a) long protocol. Firstly, patients were divided into poor (≤ 5 oocytes), medium (6–14 oocytes), and high (≥ 15 oocytes) ovarian responders based on the number of oocytes retrieved. In each group, patients were sub-divided into three groups according to the endometrial thickness on the day of hCG administration: Group A, thin endometrial thickness (≤ 7 mm); Group B, medium endometrial thickness (8–13 mm); Group C, thick endometrial thickness (≥ 14 mm). (1) For poor responders, OPRs were significantly different in the three endometrial thickness groups (28.57%, 44.25%, and 51.34%; P = 0.008). The association between thin endometrial thickness and OPR was significant after controlling for age, number of embryos transferred by multivariate logistic regression analysis (adjusted OR: 0.408; 95% CI: 0.186–0.898; P = 0.026. Reference = thick endometrial thickness). (2) For medium responders, OPRs were 31.58%, 55.56%, and 63.01% (P = 0.000) in the three groups. Adjusted OR for thin endometrial thickness was 0.284 (95% CI: 0.182–0.444; P = 0.000). (3) For high responders, OPRs were also significantly different in the three groups (28.13%, 52.63%, and 63.18; P = 0.000). Adjusted OR for thin endometrial thickness was 0.233 (95% CI: 0.105–0.514; P = 0.000). For patients undergoing IVF with different ovarian response, a thin endometrium on the day of hCG administration adversely affects ongoing pregnancy rate.
