Impacted teeth are teeth which remain embedded in the jaws past their normal eruption time or which have been blocked from their normal eruption path because of crowding of adjacent teeth or lack of enough jaw size to accommodate their eruption. Impacted teeth can cause a number of problems if left in place. Dermatoglyphics is the study of skin patterns and finger ridges that present on the fingers, toes and the soles. Fingerprint patterns of both hands were analyzed among ten patients with impacted teeth seen clinically and radiographically and equal number of healthy subjects. This study showed that tented arch pattern in index fingers of both the hands has been observed in impacted subjects thus serving as an indicator of genetic susceptibility in the incidence of dental impaction.

Background Major depressive disorder (MDD) treatment is characterized by low remission rate and often involves weeks to months of treatment. Identification of pretreatment biomarkers of response may play a critical role in novel drug development, in enhanced prognostic predictions, and perhaps in providing more personalized medicine. Using a network restricted strength predictive modeling (NRS-PM) approach, the goal of the current study was to identify pretreatment functional connectome fingerprints (CFPs) that (1) predict symptom improvement regardless of treatment modality and (2) predict treatment specific improvement. Methods Functional magnetic resonance imaging and behavioral data from unmedicated patients with MDD (n = 200) were investigated. Participants were randomized to daily treatment of sertraline or placebo for 8 weeks. NRS-PM with 1000 iterations of 10 cross-validation were implemented to identify brain connectivity signatures that predict percent improvement in depression severity at week-8. Results The study identified a pretreatment CFP that significantly predicts symptom improvement independent of treatment modality but failed to identify a treatment specific CFP. Regardless of treatment modality, improved antidepressant response was predicted by high pretreatment connectivity between modules in the default mode network and the rest of the brain, but low external connectivity in the executive network. Moreover, high pretreatment internal nodal connectivity in the bilateral caudate predicted better response. Conclusions The identified CFP may contribute to drug development and ultimately to enhanced prognostic predictions. However, the results do not assist with providing personalized medicine, as pretreatment functional connectivity failed to predict treatment specific response.

AbstractThe special formulation MA212 (Rosaxan) is composed of rosehip (Rosa canina L.) puree/juice concentrate, nettle (Urtica dioica L.) leaf extract, and devilʼs claw (Harpagophytum procumbens DC. ex Meisn. or Harpagophytum zeyheri Decne.) root extract and also supplies vitamin D. It is a food for special medical purposes ([EU] No 609/2013) for the dietary management of pain in patients with gonarthritis.This 12-week randomized, placebo-controlled double-blind parallel-design study aimed to investigate the efficacy and safety of MA212 versus placebo in patients with gonarthritis.A 3D-HPLC-fingerprint (3-dimensional high pressure liquid chromatography fingerprint) of MA212 demonstrated the presence of its herbal ingredients. Ninety-two randomized patients consumed 40 mL of MA212 (n = 46) or placebo (n = 44) daily. The Western Ontario and McMaster Universities Arthritis Index (WOMAC), quality-of-life scores at 0, 6, and 12 weeks, and analgesic consumption were documented. Statistically, the initial WOMAC subscores/scores did not differ between groups. During the study, their means significantly improved in both groups. The mean pre-post change of the WOMAC pain score (primary endpoint) was 29.87 in the MA212 group and 10.23 in the placebo group. The group difference demonstrated a significant superiority in favor of MA212 (pU < 0.001; pt < 0.001). Group comparisons of all WOMAC subscores/scores at 6 and 12 weeks reached same significances. Compared to placebo, both physical and mental quality of life significantly improved with MA212. There was a trend towards reduced analgesics consumption with MA212, compared to placebo. In the final efficacy evaluation, physicians (pChi < 0.001) and patients (pChi < 0.001) rated MA212 superior to placebo. MA212 was well tolerated.This study demonstrates excellent efficacy for MA212 in gonarthritis patients.

Annotation:

Plasma fatty acids (FAs) and oxidant status contribute to the etiology of sarcopenia in the elderly concurring to age-related muscle loss and elderly frailty through several mechanisms including changes in FA composition within the sarcolemma, promotion of chronic low-grade inflammation, and insulin resistance. The aim of this study was to determine the FA profile and pro-antioxidant status in sarcopenic frail elderly patients enrolled in a nutritional and physical activity program and to evaluate their correlation with clinical markers. Moreover, the possible changes, produced after a short-term clinical protocol, were evaluated. Plasma and erythrocyte FA composition and pro-antioxidant status were analyzed in sarcopenic elderly subjects recruited for the randomized clinical study and treated with a placebo or dietary supplement, a personalized diet, and standardized physical activity. Subjects were tested before and after 30 days of treatment. Pearson correlations between biochemical parameters and patients’ characteristics at recruitment indicate interesting features of sarcopenic status such as negative correlation among the plasma FA profile, age, and physical characteristics. Physical activity and dietetic program alone for 30 days induced a decrease of saturated FA concentration with a significant increase of dihomo-gamma-linolenic acid. Supplementation plus physical activity induced a significant decrease of linoleic acid, omega-6 polyunsaturated FAs, and an increase of stearic and oleic acid concentration. Moreover, glutathione reductase activity, which is an indicator of antioxidant status, significantly increased in erythrocytes. Changes over time between groups indicate significant differences for saturated FAs, which suggest that the amino acid supplementation restores FA levels that are consumed during physical activity. A relationship between FA and clinical/metabolic status revealed unique correlations and a specific metabolic and lipidomic fingerprint in sarcopenic elderly. The results indicate the positive beneficial role of supplementation and physical activity on plasma FA status and the antioxidant system as a co-adjuvant approach in sarcopenic, frail, elderly patients.

For the past 140 years, numerous studies have been conducted to examine minimum durations of samples needed for the recognition of acoustic parameters such as pitch, timbre or vocal phonemes. Recent studies in this field are often based on short clips (plinks) of popular songs, using target variables such as titles and interpreters. These studies provide strong evidence that a wide range of intra- and extramusical information can be identified above chance level for stimuli lasting much shorter than a second. Nevertheless, a review of precedent studies revealed a heterogeneity in stimulus generation processes that could have influenced overall recognition rates. As a piece of music unfolds in time, its timbral structure is subject to a variety of changes. We assume that the position of stimulus extraction, therefore, could influence the outcomes of a subsequent recognition task, for instance. In this study, we offer a systematic and objective stimulus extraction procedure that might help to control for (a) a possible confounding of stimulus duration and timbre (caused by the extraction of stimulus sets of various length from different song positions), (b) possible confoundings of song section and timbre (caused by the comparison of stimulus sets from divergent song sections), and (c) the suspected influence of subjective criteria on extract selection (caused by the non-randomized selection of extract positions). As an alternative approach, the suggested Matryoshka principle produces randomized sets of nested stimuli controlled for song position and objective selection. Each set represents an individual section and consists of five short excerpts, cut from each other in decreasing duration. Correlation analyses confirmed that these sets prove to be stable in terms of their mel-frequency cepstrum coefficients, the so-called “psycho-acoustic fingerprint” of a sound. Based on the software Random Plink Generator, the suggested procedure can help to contribute to an objective selection of stimuli in future plink research.

In the present study, we hypothesized that postcon (postconditioning) confers cardioprotection in vivo by reducing the production of ONOO− (peroxynitrite) and nitro-oxidative stress subsequent to the inhibition of the iNOS (inducible NO synthase). Patients with AMI (acute myocardial infarct) were randomly assigned to undergo percutaneous coronary intervention without (control) or with ischaemic postcon by three episodes of 30-s inflation and 30-s deflation of the angioplasty balloon. Animal models of MI/R (myocardial ischaemia/reperfusion) injury were induced in rats by occluding the left coronary artery for 40 min followed by 4-h reperfusion. Rats were randomized to receive vehicle, postcon (three cycles of 10-s reperfusion and 10-s coronary re-occlusion preceding full reperfusion), the selective iNOS inhibitor 1400W or postcon plus 3-morpholinosydnonimine (an ONOO− donor). Postcon in patients reduced iNOS activity in white blood cells, decreased plasma nitrotyrosine, a fingerprint of ONOO− and an index of nitro-oxidative stress, and improved cardiac function (P<0.01 compared with control). In rats, postcon reduced post-ischaemic myocardial iNOS activity and nitrotyrosine formation, reduced myocardial infarct size (all P<0.05 compared with control) and improved cardiac function. Administration of 1400W resembled, whereas 3-morpholinosydnonimine abolished, the effects of postcon. In conclusion, reduction in ONOO−-induced nitro-oxidative stress subsequent to the inhibition of iNOS represents a major mechanism whereby postcon confers cardioprotection in vivo.

Annotation:

Uncomplicated healthy pregnancy is the outcome of successful fertilization, implantation of embryos, trophoblast development and adequate placentation. Any deviation in these cascades of events may lead to complicated pregnancies such as preeclampsia (PE). The current incidence of PE is 2–8% in all pregnancies worldwide, leading to high maternal as well as perinatal mortality and morbidity rates. A number of randomized controlled clinical trials observed the association between low dose aspirin (LDA) treatment in early gestational age and significant reduction of early onset of PE in high-risk pregnant women. However, a substantial knowledge gap exists in identifying the particular mechanism of action of aspirin on placental function. It is already established that the placental-derived exosomes (PdE) are present in the maternal circulation from 6 weeks of gestation, and exosomes contain bioactive molecules such as proteins, lipids and RNA that are a “fingerprint” of their originating cells. Interestingly, levels of exosomes are higher in PE compared to normal pregnancies, and changes in the level of PdE during the first trimester may be used to classify women at risk for developing PE. The aim of this review is to discuss the mechanisms of action of LDA on placental and maternal physiological systems including the role of PdE in these phenomena. This review article will contribute to the in-depth understanding of LDA-induced PE prevention.

Users of internet browsers are constantly monitored, without their consent. By using the JavaScript APIs, it is possible to obtain various information about the browser, which together form a browser fingerprint, which can then be misused. Therefore, the goal of this work is to use a robust fingerprint protection solution of Brave browser and port it to the JavaScript Restrictor extension. In this work, the problematics of obtaining an fingerprint and countermeasures in the Brave browser are analyzed and then compared with the current protection in the JSR extension. The method of porting of Brave's countermeasures is presented and subsequently the procedure of implementation of these defense elements into the browser extension is described. The resulting implementation has been tested and evaluated, with the new protection appearing to be effective.
