The combination of nanoparticles (NPs) and surfactant may offer a novel technique of generating stronger foams for gas mobility control. This study evaluates the potential of silica NPs to enhance the foam stability of three nonionic surfactants. Results showed that the concentration of surfactant and NPs is a crucial parameter for foam stability and that there is certain concentrations for strong foam generation. A balance in concentration between the nonionic surfactants and the NPs can enhance the foam stability as a result of forming flocs in solutions...

The application of massively parallel sequencing (MPS) is growing in the forensic DNA field, as forensic DNA laboratories are continuously seeking methods to gain information from a limited or degraded forensic sample. However, the laborious nature of current MPS methodologies required for successful library preparation and sequencing leave opportunities for improvement to make MPS a practical option for processing forensic casework. In this study, the Promega PowerSeq™ Auto/Y System Prototype, a MPS laboratory workflow that incorporates multiplex amplification, was selected for optimization with the objectives to introduce automation for relieving manual processing, and to reduce the number of steps recommended by the standard protocol...

Crassiflorone is a natural product with anti-mycobacterial and anti-gonorrhoeal properties, isolated from the stem bark of the African ebony tree Diospyros crassiflora. We noticed that its pentacyclic core possesses structural resemblance to the quinone-coumarin hybrid 3, which we reported to exhibit a dual-targeted inhibitory profile towards Trypanosoma brucei glyceraldehyde-3-phosphate dehydrogenase (TbGAPDH) and Trypanosoma cruzi trypanothione reductase (TcTR). Following this basic idea, we synthesized a small library of crassiflorone derivatives 15-23 and investigated their potential as anti-trypanosomatid agents...

Background/Aim: Antiviral treatment for patients in HBeAg-positive chronic hepatitis B virus (HBV) infection is still controversial. We assessed whether antiviral treatment reduces liver disease progression in those patients. Methods: This study included consecutive patients that tested positive for HBeAg with an HBV DNA >20,000 IU/mL, ALT <40 IU/L and without evidence of cirrhosis in eight large-volume hospitals in Korea. The primary endpoint was the development of hepatocellular carcinoma (HCC) and the secondary endpoint was the development of cirrhosis...

Many female parasitoid wasps optimize host selection to balance the benefits of high-quality hosts and the costs of predator- or hyperparasitoid-induced mortality risks to maximize their fitness. Cannibalism exists in many insect species and affects survival of parasitoid larvae developing in or on parasitized hosts. However, little is known about how parasitoid wasps resolve the fitness consequence of host cannibalism-induced mortality risk during host selection. We examined the effect of oothecal age on cannibalism in the American cockroach Periplaneta americana (L...

Dietary plant cell wall carbohydrates are important in modulating the composition and metabolism of the complex gut microbiota, which can impact on health. Pectin is a major component of plant cell walls. Based on studies in model systems and available bacterial isolates and genomes, the capacity to utilize pectins for growth is widespread among colonic Bacteroidetes but relatively uncommon among Firmicutes. One Firmicutes species promoted by pectin is Eubacterium eligens. E. eligens DSM3376 utilizes apple pectin and encodes a broad repertoire of pectinolytic enzymes, including a highly abundant pectate lyase of around 200 kDa that is expressed constitutively...

Publicly (mainly Medicaid) funded long-term care (LTC) services have evolved from a nursing home dominated system of service to a much more balanced system including home- and community-based services (HCBS) programs over the last 30 years. The HCBS programs have been largely administered by the state and local level nonprofit aging networks (ANs) consisting of Area Agencies on Aging and thousands of service providers. Over the last decade, however, for-profit HMOs administered primarily by large insurance companies have begun to displace AN organizations...

<p>Gender plays a significant role in determining facial anatomy and behavior, both of which are key factors in the aging process. Understanding the pattern of male facial aging is critical when planning aesthetic treatments on men. Men develop more severe rhytides in a unique pattern, show increased periocular aging changes, and are more prone to hair loss. What also needs to be considered when planning a treatment is what makes men beautiful or "man-some". Male beauty strikes a balance between masculine and feminine facial features...

: The case presented describes a very rare cause of 'needle-like' chest pain in a 52-year-old Egyptian man. A sharp 38-mm long needle was detected in the lateral wall of the right ventricle by means of cardiac computed tomography scan. After heart team discussion, the patient underwent minimally invasive cardiac surgery intervention. The needle was successfully removed though left minithoracotomy, and the patient was discharged home on the 5th day. The diagnosis of intracardiac foreign bodies may be challenging...

Epidemiology is the study of how disease is distributed in populations and the factors that influence or determine this distribution. Clinical epidemiology denotes the application of epidemiologic methods to questions relevant to patient care and provides a highly useful set of principles and methods for the design and conduct of quantitative clinical research. Validly analyzing, correctly reporting, and successfully interpreting the findings of a clinical research study often require an understanding of the epidemiologic terms and measures that describe the patterns of association between the exposure of interest (treatment or intervention) and a health outcome (disease)...

BACKGROUND: Virtual Reality (VR) balance training may have advantages over regular exercise training in older adults. However, results so far are conflicting potentially due to the lack of challenge imposed by the movements in those games. Therefore, the aim of this study was to assess to which extent two similar skiing games challenge balance, as reflected in center of mass (COM) movements relative to their Functional Limits of Stability (FLOS). METHODS: Thirty young and elderly participants performed two skiing games, one on the Wii Balance board (Wiiski), which uses a force plate, and one with the Kinect sensor (Kinski), which performs motion tracking...

Aminoferrocene-based prodrugs are activated in cancer cells by reactive oxygen species (ROS). They were shown to exhibit high cytotoxicity towards a variety of cancer cell lines and primary cancer cells, but remain not toxic towards non-malignant cells. However, these prodrugs have rather high lipophilicity leading to relatively low water solubility. In particular, an n-octanol/water partition coefficient for the best aminoferrocene-based prodrug (2) was found to be 4.51±0.03. Though the approaches for decreasing lipophilicity are straightforward and include the addition of polar residues to the drug structure, these modifications also lead to dramatic decrease of cell permeability and, correspondingly, lower the activity of the drug...

In this report, the solubilization behaviour of a hydrophobic drug Clozapine (CLZ) in micellar suspensions of pluronics having different hydrophilic lipophilic balance (HLB) ratios viz. P84, F127 and F108 in the absence and presence of bile salt sodium deoxycholate (SDC) has been studied. UV-Vis spectroscopy has been exploited to determine the solubilization capacity of the investigated micellar systems in terms of drug loading efficiency, average number of drug molecules solubilized per micelle (ns), partition coefficient (P) and standard free energy of solubilization (∆G(°))...

Pharmaceuticals are beginning to receive attention as a source of pollution in aquatic environments. Yet the impact of physician prescription patterns on water resources is not often discussed in clinical decision making. Here, we comment on a case in which empiric antibiotic treatment might benefit a patient while simultaneously being detrimental to the aquatic environment. We first highlight the potential harm caused by this prescription from its production to its disposal. We then suggest that Van Rensselaer Potter's original conceptualization of bioethics can be used to balance clinicians' obligations to protect individual, public, and environmental health...

Cationic antimicrobial peptides (AMPs) and polymers are active against many multi-drug resistant (MDR) bacteria but only a limited number of these compounds are in clinical use due to their unselective toxicity. The typical strategy for achieving selective antibacterial efficacy with low mammalian cell toxicity is through balancing the ratio of cationicity to hydrophobicity. Herein, we report a cationic nanoparticle self-assembled from chitosan-graft-oligolysine (CSM5-K5) chains with ultra-low molecular weight (1450 Daltons) that selectively kills bacteria...
