In vitro antibacterial and antifungal activity of a skin ointment and its active pharmaceutical ingredients larch turpentine, turpentine oil, and eucalyptus oil.

Introduction: Turpentine derivatives and Eucalyptus oil are herbal substances traditionally used to treat various skin infections. Limited non-clinical data suggest they exert an immunological activity, but only scant information exists on their antibiotic effects. This in vitro study has been carried out to investigate the antibacterial and antifungal activity of a marketed skin ointment, its active pharmaceutical ingredients larch turpentine, eucalyptus oil, and turpentine oil, and their mixture, against bacteria and yeasts commonly present on the skin and causing skin infections.

MIBiG 4.0: advancing biosynthetic gene cluster curation through global collaboration.

Specialized or secondary metabolites are small molecules of biological origin, often showing potent biological activities with applications in agriculture, engineering and medicine. Usually, the biosynthesis of these natural products is governed by sets of co-regulated and physically clustered genes known as biosynthetic gene clusters (BGCs). To share information about BGCs in a standardized and machine-readable way, the Minimum Information about a Biosynthetic Gene cluster (MIBiG) data standard and repository was initiated in 2015.

Isolation of Single Donors in ZnO.

The shallow donor in zinc oxide (ZnO) is a promising semiconductor spin qubit with optical access. Single indium donors are isolated in a commercial ZnO substrate using plasma focused ion beam (PFIB) milling. Quantum emitters are identified optically by spatial and frequency filtering.

In Vitro Anti-inflammatory Effects of Larch Turpentine, Turpentine Oil, Eucalyptus Oil, and Their Mixture as Contained in a Marketed Ointment.

An ointment containing larch turpentine, turpentine oil, and eucalyptus oil has been used for almost a century for the symptomatic treatment of mild, localized, purulent inflammations of the skin. Its clinical efficacy in the treatment of skin infections has been shown in clinical trials, but the mode of action of the active ingredients on inflammation is not known. We studied the anti-inflammatory properties of the active ingredients of the ointment and their mixture in a human monocyte cell model, in which the cells were stimulated with lipopolysaccharide and incubated with the test substances.

Bi-directionalized promoter systems allow methanol-free production of hard-to-express peroxygenases with Komagataella Phaffii.

Background: Heme-incorporating peroxygenases are responsible for electron transport in a multitude of organisms. Yet their application in biocatalysis is hindered due to their challenging recombinant production. Previous studies suggest Komagataella phaffi to be a suitable production host for heme-containing enzymes.

Effect of allyl-isothiocyanate on survival and antimicrobial peptide expression following oral bacterial infections in .

Since infections with antibiotic-resistant bacteria cause increasing problems worldwide, the identification of alternative therapies is of great importance. Plant-derived bioactives, including allyl-isothiocyanate (AITC), have received attention for their antimicrobial properties. The present study therefore investigates the impact of AITC on survival and antimicrobial peptide (AMP) levels in challenged with the fly pathogenic bacteria subsp.

Cyanovirin-N Binding to -Acetyl-d-glucosamine Requires Carbohydrate-Binding Sites on Two Different Protomers.

Cyanovirin-N (CV-N) binds high-mannose oligosaccharides on enveloped viruses with two carbohydrate-binding sites, one bearing high affinity and one low affinity to Manα(1-2)Man moieties. A tandem repeat of two CV-N molecules (CVN2) was tested for antiviral activity against human immunodeficiency virus type I (HIV-1) by using a domain-swapped dimer. CV-N was shown to bind -acetylmannosamine (ManNAc) and -acetyl-d-glucosamine (GlcNAc) when the carbohydrate-binding sites in CV-N were free to interact with these monosaccharides independently.

Turpentine Ointment for the Treatment of Folliculitis: An Open, Prospective, Randomized, Placebo- and Comparator-Controlled Multicenter Trial.

Introduction: Folliculitis is a painful infection and inflammation of the hair follicles, mostly caused by bacterial, fungal, or, more rarely, viral infections. Turpentine derivatives have been used traditionally to treat various skin infections and could thus also be effective in treating folliculitis. We carried out an open, prospective, randomized, placebo- and comparator-controlled multicenter trial to evaluate the efficacy and safety of an ointment containing pine turpentine oil, larch turpentine, and eucalyptus oil in the treatment of acute folliculitis.

FunOrder 2.0 - a method for the fully automated curation of co-evolved genes in fungal biosynthetic gene clusters.

Coevolution is an important biological process that shapes interacting proteins - may it be physically interacting proteins or consecutive enzymes in a metabolic pathway, such as the biosynthetic pathways for secondary metabolites. Previously, we developed FunOrder, a semi-automated method for the detection of co-evolved genes, and demonstrated that FunOrder can be used to identify essential genes in biosynthetic gene clusters from different ascomycetes. A major drawback of this original method was the need for a manual assessment, which may create a user bias and prevents a high-throughput application.

Shallow donors in ZnO are promising candidates for photon-mediated quantum technologies. Utilizing the indium donor, we show that favorable donor-bound exciton optical and electron spin properties are retained in isolated ZnO nanowires. The inhomogeneous optical line width of single nanowires (60 GHz) is within a factor of 2 of bulk single-crystalline ZnO.

Impact of Food-Derived Bioactive Compounds on Intestinal Immunity.

The gastrointestinal system is responsible for the digestion and the absorption of nutrients. At the same time, it is essentially involved in the maintenance of immune homeostasis. The strongest antigen contact in an organism takes place in the digestive system showing the importance of a host to develop mechanisms allowing to discriminate between harmful and harmless antigens.

On the permittivity of titanium dioxide.

Conductive rutile TiO has received considerable attention recently due to multiple applications. However, the permittivity in conductive, reduced or doped TiO appears to cause controversy with reported values in the range 100-10,000. In this work, we propose a method for measurements of the permittivity in conductive, n-type TiO that involves: (i) hydrogen ion-implantation to form a donor concentration peak at a known depth, and (ii) capacitance-voltage measurements for donor profiling.

Digestive enzyme expression in the large intestine of children with short bowel syndrome in a late stage of adaptation.

Background And Aims: Intestinal adaptation in short bowel syndrome (SBS) includes morphologic processes and functional mechanisms. This study investigated whether digestive enzyme expression in the duodenum and colon is upregulated in SBS patients.

Method: Sucrase-isomaltase (SI), lactase-phlorizin hydrolase (LPH), and neutral Aminopeptidase N (ApN) were analyzed in duodenal and colonic biopsies from nine SBS patients in a late stage of adaptation as well as healthy and disease controls by immunoelectron microscopy (IEM), Western blots, and enzyme activities.

Effects of Live and Heat-Inactivated Strains and Their Supernatants on Immune Regulation in HT-29 Cells.

Probiotics are considered to have a beneficial impact on humans, but in some cases, administration of live microorganisms might be risky. In the present study, immunomodulatory effects of different strains and their super-natants were examined under different inflammatory conditions with living and heat-inactivated strains. HT-29 cells were incubated with strains (S2-G1, S2-G3, S2-G4 and S2-G8) and their supernatants with or without stimulation with tumor necrosis factor alpha (TNF-α) or interleukin (IL)-1β.

Epithelial transport of immunogenic and toxic gliadin peptides in vitro.

Scope: Celiac disease is an autoimmune disorder caused by failure of oral tolerance against gluten in genetically predisposed individuals. The epithelial translocation of gluten-derived gliadin peptides is an important pathogenetic step; the underlying mechanisms, however, are poorly understood. Thus, we investigated the degradation and epithelial translocation of two different gliadin peptides, the toxic P31-43 and the immunogenic P56-68.

Gamma-linolenic acid levels correlate with clinical efficacy of evening primrose oil in patients with atopic dermatitis.

Introduction: Atopic dermatitis (AD) has been related to a deficiency of delta-6-desaturase, an enzyme responsible for the conversion of linoleic acid to gamma-linolenic acid (GLA). Evening primrose oil (EPO) contains high amounts of GLA. Therefore, this study investigated whether EPO supplementation results in an increase in plasma GLA and its metabolite dihomo-gamma-linolenic acid (DGLA) correlating with clinical improvement of AD, assessed by the SCORing Atopic Dermatitis (SCORAD) index.
