Standard Techniques

The standard techniques for diagnosis of human filariasis are the microscopic examination of blood smears or skin biopsies, which are relatively invasive and poorly sensitive at low levels of infection. Recently, filarial DNA has been detected in fecal samples from non-human primates in Central Africa. The aim of this study was to demonstrate proof-of-concept of a non-invasive molecular diagnosis technique for human filariasis by targeting fragments of 12S rDNA, Cox1, ITS1 and LL20-15kDa ladder antigen-gene by conventional PCR in DNA extracted from stool samples of 52 people infected with Mansonella perstans and/or Loa loa. Of these, 10 patients were infected with soil-transmitted helminths (Trichuris trichiura and/or Ascaris lumbricoides), and none were positive for Necator americanus. Interestingly, no filarial gene fragments were detected in the stools of any of the 52 patients. Future studies should evaluate whether a co-infection with soil-transmitted helminths causing gastrointestinal bleeding and likely allowing (micro)filaria exit into the digestive tract, may facilitate the molecular detection of filarial DNA fragments in stool samples.

Shielding skirts are widely used as a non-invasive preventive measure against salmon lice Lepeophtheirus salmonis infestations on Atlantic salmon Salmo salar in sea-cages. Low levels of dissolved oxygen (DO) are reported from some sites, but not others. This disparity is usually explained by local variations in current flow and hydrography. The aim of the present study was to investigate these local variations through vertical mapping of DO and hydrography at 2 hydrographically different sites equipped with shielding skirts. The 2 sites chosen, Fornes and Soløya, are in northern Norway and are equipped with a permeable and a non-permeable skirt, respectively. Over a period of 3 d, current speed and direction were recorded outside the cage, while DO and hydrography were measured both inside and outside the cage, above and below the skirt. At Fornes, the DO inside the cage varied throughout the study period, while DO outside remained stable. The variation in DO inside the cage co-occurred with variations in strength and depth of a present pycnocline that broke down during the study period. At Soløya, DO levels were high throughout the study, and there was no gradient in salinity, temperature or density, indicating good vertical mixing. These data illustrate how the interaction between skirts and local conditions can influence the temporal and spatial variations of DO inside shielded cages and highlight the importance of studying local current conditions and hydrography when applying shielding skirts.

The aims of this paper was to determine the effect of self-myofascial release (SMFR) on postural stability and to analyze if it can influence migraine condition. Twenty-five subjects (age 49.7± 12.5) affected by migraine were enrolled. Assessments included a stabilometric analysis in order to evaluate balance and plantar support, with eyes open (OE) and closed (CE); cervical ROM measurement; evaluation of upper limb strength through handgrip. All the analysis were carried out before and after the administration of a single SMFR protocol, using medium density small balls laid in the three most painful trigger points in migraine patients: trapezius, sternocleidomastoids and suboccipital muscles. Performing a T test for paired samples, there was a significant increase in two ranges of the stabilometric analysis: ellipse surface, both with open and closed eyes (p value EO = 0.05; p value EC = 0.04) and length of the sway path, but just with closed eyes (p value = 0.05). SMFR might have a positive impact on postural stability in subjects with migraine. Further investigation should be conducted to confirm the hypothesis.

In recent years, meat authenticity awareness has increased and, in the fight to combat meat fraud, various analytical methods have been proposed and subsequently evaluated. Although these methods have shown the potential to detect low levels of adulteration with high reliability, they are destructive, time-consuming, labour-intensive, and expensive. Therefore, rendering them inappropriate for rapid analysis and early detection, particularly under the fast-paced production and processing environment of the meat industry. However, modern analytical methods could improve this process as the food industry moves towards methods that are non-destructive, non-invasive, simple, and on-line. This review investigates the feasibility of different non-destructive techniques used for processed meat authentication which could provide the meat industry with reliable and accurate real-time monitoring, in the near future.

What potent blood hath modest May,What fiery force the earth renews,The wealth of forms, the flush of hues ….—Ralph Waldo EmersonSomeday soon, virtually any pregnant woman will be able to learn — with 98-99% accuracy — whether her fetus has contracted a serious genetic disorder by undergoing nothing more than an inexpensive, non-invasive blood test. For years, scientists have sought a method of prenatal testing that could boast both high levels of accuracy and low levels of risk. The most promising solution lies in an exciting recent discovery: tiny quantities of fetal cells and DNA cross over into the mother's bloodstream during pregnancy. If the fetal genetic material can be successfully isolated from the maternal blood, it can be used to diagnose a number of genetic disorders, such as Down Syndrome, cystic fibrosis, Tay-Sachs disease, and sickle cell anemia. Indeed, researchers have spent the last decade developing ways to accomplish this.

Erratic Behavior

Mercury (Hg) is a non-essential metal, sometimes extremely toxic, and its presence in the food-web may threaten the wildlife. In seabirds, even low levels of Hg can reduce egg production and the chances of embryos and chicks survival; high levels of this element lead to erratic behavior, loss of appetite and weight, and cellular damages in organs as kidneys can be detected. According to some authors, among 50 to 93% of the total Hg accumulated by the birds through diet can be excreted throughout the feathers during the molting process. In this way, feathers can be used as an excellent non-invasive biomonitor. The objective of this paper was to compared mercury (Hg) levels in feathers of adults and chicks of Catharacta maccormicki(Cma) and C. lonnbergi (Clo) sampled in the Antarctic Peninsula, to identify biomonitors of Hg to the region using non-invasive samples methods. We found Hg significantly higher levels in adults of Cma comparing with Clo adults (U'=841.00, p<0.01) and also with chicks of both species (q>3.398, p<0.01).  We did not find significant differences comparing Clo adults and chicks of both species (U'=16.00, p<0.05), and comparing Cma breeding in different areas (q>3.398, p<0.05) or Clo (U'= 62.00, p < 0.05). The Hg levels variation may be justified mainly by differences in migration patterns. The adults of the species that migrate to more polluted areas (Cma) presented the highest levels of Hg and can be considered a promising indicator of global contamination. In another way, Clo and chicks of both species are good indicators of local Hg contamination, suffering the direct influence of contamination in the Antarctic environment.
