The β roll molecules with sequence (GAGAGAGQ)10 stack via hydrogen bonding to form fibrils which have been themselves been used to make viral capsids of DNA strands, supramolecular nanotapes and pH-responsive gels. Accelerated molecular dynamics (aMD) simulations are used to investigate the unfolding of a stack of two β roll molecules, (GAGAGAGQ)10, to shed light on the folding mechanism by which silk-inspired polypeptides form fibrils and to identify the dominant forces that keep the silk-inspired polypeptide in a β roll configuration...

Multifunctional and multi-responsive hydrogels have presented a promising platform to design and fabricate smart devices for application in a wide variety of fields. However, their preparations often involve multistep preparation of multi-responsive polymer precursors, tedious reactions to introduce functional groups or sophisticated molecular designs. In this work, a multifunctional boronic acid-based crosslinker bis(phenylboronic acid carbamoyl) cystamine (BPBAC) was readily prepared from inexpensive commercially available 3-carboxylphenylboronic acid (CPBA) and cystamine dihydrochloride, which has the ability to crosslink the cis-diols and catechol-containing hydrophilic polymers to form hydrogels...

The apothecary occupied a liminal position in early modern society between profit and healing. Finding ways to distance their public image from trade was a common problem for apothecaries across Europe. This article uses the case of a Bolognese apothecary, Filippo Pastarino, to address the question of how early modern apothecaries chose to represent themselves to political authorities and to the wider public. 'Mercy', alongside 'craft', was a pillar of apothecaries' social identity. By contrast, no matter how central financial transactions ('money') were to their activity, apothecaries did not want to be perceived as merchants...

PURPOSE: The dynamic intraligamentary stabilization (DIS) technique is based on a different treatment approach than ACL reconstruction in that it intends to promote self-healing of the ligament. It is only recommended for acute injuries (<21days). The purpose of the present study was to compare DIS and ACLR with respect to the extent of work incapacity, revision rates, secondary arthroscopies, and treatment costs during recovery. METHODS: The study was a post-hoc analysis of prospectively collected data in the Swiss National Accident Insurance Fund (SUVA) database...

Beyond the physiology of reproduction, estrogen controls the homeostasis of several tissues. Although macrophages play a key role in tissue remodeling, the interplay with estrogen is still ill defined. Using a transcriptomic approach we first obtained a comprehensive list of genes that are differentially expressed in peritoneal macrophages in response to physiological levels of 17β-estradiol (E2) injected in intact female mice. Our data also showed the dynamic nature of the macrophage response to E2 and pointed to specific biological programs induced by the hormone, with cell proliferation, immune response and wound healing being the most prominent functional categories...

Epigenetic mechanisms such as DNA methylation are increasingly recognized to be critical for vaccination efficacy and outcome of different infectious diseases, but corresponding information is scarcely available for host defense against malaria. In the experimental blood-stage malaria Plasmodium chabaudi, we investigate the possible effects of a blood-stage vaccine on DNA methylation of gene promoters in the liver, known as effector against blood-stage malaria, using DNA methylation microarrays. Naturally susceptible Balb/c mice acquire, by protective vaccination, the potency to survive P...

Background Irritable bowel syndrome (IBS) has a complex pathology, high prevalence and large impact on patients' quality of life. As conventional therapy may yield unsatisfactory results, a more holistic approach may be desirable. The current study assessed the effect of micro-physiotherapy on the severity of IBS symptoms. Methods In a double-blind study, 61 recurrent IBS patients were randomised to two sessions of micro-physiotherapy or sham micro-physiotherapy. Inclusion criteria were the presence of ≥1 IBS symptom from abdominal pain, constipation, diarrhoea or bloating...

Communication between physicians and patients is a key pillar of psychosocial support for enhancing the healing process of patients and for increasing their well-being and quality of life. Physicians and other health professionals might benefit from interventions that increase their self-care, awareness, compassion, and other-focused concern, and reduce the chances of distress and burnout. There is substantial evidence for the contribution of different management strategies to achieve these aims. The goal of this article is to review the potential effect of mindfulness and compassion-based strategies for the improvement of physician-patient interactions...

Self-healing capability helps biological systems to maintain their survivability and extend their lifespan. Similarly, self-healing is also beneficial to next-generation secondary batteries because high-capacity electrode materials, especially the cathodes such as oxygen or sulfur, suffer from shortened cyclic lives resulting from irreversible and unstable phase transfer. Herein, by mimicking a biological self-healing process, fibrinolysis, we introduced an extrinsic healing agent, polysulfide, to enable the stable operation of sulfur microparticle (SMiP) cathodes...

The regeneration of articular cartilage, which scarcely shows innate self-healing ability, is a great challenge in clinical treatment. Stem cell-derived exosomes (SC-Exos), an important type of extracellular nanovesicle, exhibit great potential for cartilage regeneration to replace stem cell-based therapy. Cartilage regeneration often takes a relatively long time and there is currently no effective administration method to durably retain exosomes at cartilage defect sites to effectively exert their reparative effect...

Growth factors and cytokines control cell growth, proliferation and differentiation via a network of inter- and intracellular signalling pathways, and are involved in skin self-renewing and wound healing. In recent years, topical and injectable growth factors and cytokines have emerged as an intriguing therapeutic modality that can be harnessed for aesthetic purposes. However, very little data are available on their long-term safety and tolerability. In this report, we describe two cases of patients, who developed intramuscular lipoma of the chin following topical injection with a mixture of basic fibroblast growth factor as the main ingredients for chin augmentation...

BACKGROUND: The safety of augmentation mastopexy has been questioned. Staging has been recommended for women deemed to be at higher risk, such as women with greater degrees of ptosis. Most existing studies evaluate women treated with multiple methods, including the traditional Wise pattern. This retrospective study specifically evaluates vertical augmentation mastopexy. A simple algorithm is introduced. METHODS: From 2002 to 2016, 252 women underwent consecutive vertical augmentation mastopexies performed by the author, with no staged surgery...

Factitious ulcers are characterized by self-inflicted lesions with multifactorial origin. These lesions are frequently found in head, neck, and hands. This report shows a 6-year-old boy diagnosed with factitious oral ulcers that occurred after the self-biting of buccal vestibule and nail-scratching of gingival tissue. Clinically, a significant swelling was observed, hard on palpation, located at the right lower third of the face, next to the posterior area of the mandible. In the intraoral examination, ulcers at different healing stages were noted on the swelling area...

BACKGROUND AND AIMS: A good therapeutic alliance plays a major role in the healing process. Professionals working in addiction treatment report high levels of psychological distress related to work and this may challenge the establishment of a trustful therapeutic alliance, and lead to a loss of care quality provided to service users. The purpose of this study was to investigate the experience of specialized professionals, its effects on trust and the therapeutic alliance, and the means to restore them...

BACKGROUND: Dysvascular partial foot amputation (PFA) is a common sequel to advanced peripheral vascular disease. Helping inform difficult discussions between patients and practitioners about the level of PFA, or the decision to have a transtibial amputation (TTA) as an alternative, requires an understanding of the current research evidence on a wide range of topics including wound healing, reamputation, quality of life, mobility, functional ability, participation, pain and psychosocial outcomes, and mortality...

Fabrication of composite scaffolds using stereolithography (SLA) for bone tissue engineering has shown great promises. However, in order to trigger effective bone formation and implant integration, exogenous growth factors are commonly combined to scaffold materials. In this study, we fabricated biodegradable composite scaffolds using SLA and endowed them with osteopromotive properties in the absence of biologics. First we prepared photo-crosslinkable poly(trimethylene carbonate) (PTMC) resins containing 20 and 40 wt...

Cutaneous leishmaniasis (CL), a common condition in many parts of the world, is being increasingly encountered in non-endemic countries secondary to immigration. The clinical manifestations and course can vary substantially, with appropriate management ranging from observation for self-healing lesions to urgent treatment to prevent damaging anatomical and cosmetic sequelae. While there are now several effective medications, optimal therapy is not well defined, and decision-making can be challenged by the location of lesions and various drug issues, including availability, mode of delivery and adverse effects...
