Contingency quality of a custom made computer vision algorithm for calculating lower back backbone movement through RGB-D digicam detail information.
In vitro assays showed that the crosslinking has conferred the biomaterial with superior mechanical property and anti-calcification property, ability to promote smooth muscle cell adhesion and upregulate functional genes expression. Using a rabbit model with bladder defects, we demonstrated that the PC-SIS scaffold can rapidly promote in situ tissue regrowth and regeneration, in particular smooth muscle remodeling and improvement of urinary functions. The PC-SIS scaffold has therefore provided a promising material for the reconstruction of a functional bladder.[This corrects the article DOI 10.1016/j.bioactmat.2018.08.003.][This corrects the article DOI 10.1016/j.bioactmat.2019.10.004.][This corrects the article DOI 10.1016/j.bioactmat.2018.01.005.][This corrects the article DOI 10.1016/j.bioactmat.2017.08.002.][This corrects the article DOI 10.1016/j.bioactmat.2019.10.003.][This corrects the article DOI 10.1016/j.bioactmat.2018.11.001.][This corrects the article DOI 10.1016/j.bioactmat.2020.01.011.][This corrects the article DOI 10.1016/j.bioactmat.2018.05.003.][This corrects the article DOI 10.1016/j.bioactmat.2018.10.001.].Vascular diseases are the most prevalent cause of ischemic necrosis of tissue and organ, which even result in dysfunction and death. Vascular regeneration or artificial vascular graft, as the conventional treatment modality, has received keen attentions. However, small-diameter (diameter less then 4 mm) vascular grafts have a high risk of thrombosis and intimal hyperplasia (IH), which makes long-term lumen patency challengeable. Endothelial cells (ECs) form the inner endothelium layer, and are crucial for anti-coagulation and thrombogenesis. Thus, promoting in situ endothelialization in vascular graft remodeling takes top priority, which requires recruitment of endothelia progenitor cells (EPCs), migration, adhesion, proliferation and activation of EPCs and ECs. Chemotaxis aimed at ligands on EPC surface can be utilized for EPC homing, while nanofibrous structure, biocompatible surface and cell-capturing molecules on graft surface can be applied for cell adhesion. Moreover, cell orientation can be regulated by topography of scaffold, and cell bioactivity can be modulated by growth factors and therapeutic genes. Additionally, surface modification can also reduce thrombogenesis, and some drug release can inhibit IH. Considering the influence of macrophages on ECs and smooth muscle cells (SMCs), scaffolds loaded with drugs that can promote M2 polarization are alternative strategies. In conclusion, the advanced strategies for enhanced long-term lumen patency of vascular grafts are summarized in this review. Strategies for recruitment of EPCs, adhesion, proliferation and activation of EPCs and ECs, anti-thrombogenesis, anti-IH, and immunomodulation are discussed. Ideal vascular grafts with appropriate surface modification, loading and fabrication strategies are required in further studies.[This corrects the article DOI 10.1016/j.bioactmat.2018.05.004.][This corrects the article DOI 10.1016/j.bioactmat.2018.12.004.][This corrects the article DOI 10.1016/j.bioactmat.2020.04.006.][This corrects the article DOI 10.1016/j.bioactmat.2018.03.003.][This corrects the article DOI 10.1016/j.bioactmat.2019.12.003.][This corrects the article DOI 10.1016/j.bioactmat.2018.12.003.][This corrects the article DOI 10.1016/j.bioactmat.2018.05.005.][This corrects the article DOI 10.1016/j.bioactmat.2018.09.001.][This corrects the article DOI 10.1016/j.bioactmat.2018.07.001.][This corrects the article DOI 10.1016/j.bioactmat.2018.12.002.][This corrects the article DOI 10.1016/j.bioactmat.2018.05.001.][This corrects the article DOI 10.1016/j.bioactmat.2018.11.002.][This corrects the article DOI 10.1016/j.bioactmat.2018.06.002.][This corrects the article DOI 10.1016/j.bioactmat.2018.08.001.][This corrects the article DOI 10.1016/j.bioactmat.2019.01.002.].Current contraceptive methods come with a number of drawbacks, including low efficacy, in the case of commercial contraceptive gels, and a reduction in the quality of sexual intercourse, in the case of condoms. Adding pharmacologically-active agents to contraceptive gels holds the potential to improve sexual experience, and hardbor safety and hygiene. In this study, we fabricated a Carbomer-based contraceptive gel consisting of three agents tenofovir, gossypol acetate, and nitroglycerin (TGN), with pH adjusted to 4.5 (to be compatible with the vagina). In vitro, the gossypol component of the contraceptive gel proved to be a significantly effective spermicide. When the concentration of gossypol acetate was 10 mg/ml, the spermicidal ability reached 100% after 30s. In addition, tenofovir in the gel significantly inhibited lentiviral transfection efficiency in cell-containing media. In 6 pairs of rats, the gel successfully prevented all females from conceiving after successful mating. Moreover, increased sexual frequency and enhanced erection, which were promoted by the nitroglycerin in the components, were observed in male rats that had the gel applied to their penises. This novel TGN contraceptive gel yielded a higher contraceptive success rate than that of the commercial contraceptive gel (Contragel®). In addition, it has the added benefits to prevent sexually transmitted diseases and improve male libido and erection function during sexual intercourse. Combining three FDA-approved and marketed agents together, our trifunctional TGN gel has a great potential for further translation and commercialization.
Non-inferiority (NI) analysis is not usually considered in the early phases of clinical development. In some negative phase II trials, a post-hoc NI analysis justified additional phase III trials that were successful. However, the risk of false positive achievements was not controlled in these early phase analyses. We propose to preplan NI analyses in superiority-based Simon's two-stage designs to control type I and II error rates.

Simulations have been proposed to assess the control of type I and II errors rates with this method. A total of 12,768 two-stage Simon's design trials were constructed based on different assumptions of rejection response probability, desired response probability, type I and II errors, and NI margins. P-value and type II error were calculated with stochastic ordering using Uniformly Minimum Variance Unbiased Estimator. Type I and II errors were simulated using the Monte Carlo method. The agreement between calculated and simulated values was analyzed with Bland-Altman plots.

We observed the same level of agreement between calculated and simulated type I and II errors from both two-stage Simon's superiority designs and designs in which NI analysis was allowed. Different examples has been proposed to explain the utility of this method.

Inclusion of NI analysis in superiority-based single-arm clinical trials may be useful for weighing additional factors such as safety, pharmacokinetics, pharmacodynamic, and biomarker data while assessing early efficacy. Implementation of this strategy can be achieved through simple adaptations to existing designs for one-arm phase II clinical trials.

We reapplied an organ size-based in vivo monitoring system, exploring the autocatabolism-related alterations evoked by Aβ42, in a glucose-supplemented starvation model. The experientially easy-to-follow size reduction of the bilateral reproductive organ (germovitellaria) in fasted rotifers was rescued by Aβ42, serving as a nutrient source- and peptide sequence-specific attenuator of the organ shrinkage phase and enhancer of the regenerative one including egg reproduction. c-RET inhibitor Recovery of the germovitellaria was significant in comparison with the greatly shrunken form. In contrast to the well-known neurotoxic Aβ42 (except the bdelloids) with specific regulatory roles, the artificially designed scrambled version (random order of amino acids) was inefficient in autocatabolism attenuation, behaving as negative control. This native Aβ42-related modulation of the 'functionally reversible organ shrinkage' can be a potential experiential and supramolecular marker of autocatabolism in vivo.
Diabetes mellitus (DM) is a public health problem, which requires enhanced self-care in order to avoid complications. However, cognitive impairment can reduce these abilities and may affect health literacy (HL) of patients in terms to understand and apply information. Therefore, this study evaluated the correlation between cognitive condition and HL related to medication adherence, physical activity and nutritional status among people living with DM.

A cross-sectional study was carried out among elderly people (≥ 60 years old) with DM. The cognitive condition was evaluated using the Mini-Mental State Examination (MMSE) and the HL using the following questionnaires Literacy Assessment for Diabetes (LAD-60), Nutritional Literacy among People with Diabetes (NLD), Health Literacy on the Practice of Physical Activities among Diabetics (HLPPA - D), and Health Literacy regarding Drug Adherence among Diabetics (HLDA-D). link2 Sociodemographic and biochemical profile was also evaluated. Spearman correlation was used (p < 0.05).

187 individuals with DM were included. Regarding laboratory analyses, insulin dosage had a mean value of 12.3 microUI/mL (SD ±15.7), mean blood glucose was 148.1 mg/dl (SD ±59.7) and mean HbA1c was 7.54 % (SD ±1.8). In the correlation analysis, higher age and lower income were weakly correlated with lower cognitive level. No correlation was identified for biochemical variables and cognitive condition. A positive and weak correlation between cognition and HL was observed in the studied population.

In older people living with DM the cognitive condition is correlated to specific topics of HL (nutritional status, physical activity and medication adherence).

Mental disorders increase the risk factor for developing physical comorbidity conditions, such as cardiometabolic diseases. There is a high prevalence of multimorbidity and polypharmacy in the elderly population which hampers clinical response. Studies have shown that this positive correlation between the aging process and enhancement of physical comorbidities is especially high among older adults who live in low or middle income countries.

To investigate the association between physical disease comorbidities and polypharmacy in older adults with a clinical diagnosis of Alzheimer's disease (AD), mild cognitive impairment (MCI) or major depressive disorder (MDD), living in a middle income country.

Cross-sectional study of community-dwelling elderly individuals who are cognitively healthy and those with AD, MCI, or MDD. The severity scale of the Charlson Comorbidity Index (CCI) was calculated to classify the severity of comorbidity condition. link3 Logistic regression model (unadjusted and adjusted for age) were used to calculate odds ratios (OR) and 95 % confidence intervals (CI) for cardiometabolic comorbidity (hypertension, diabetes, dyslipidemia and overweight), and polypharmacy.
