Abstract
PURPOSE CSMed® wound dressing, a dressing with various herb extracts, was tested for its therapeutic effect in radiation dermatitis of breast and head-and-neck cancer patients. METHODS This study included 20 breast cancer patients and 10 head-and-neck cancer patients. Half of the irradiated area was covered with CSMed® and the other half was under routine treatment. The severity of radiation dermatitis was evaluated with radiation therapy oncology group (RTOG) grade throughout the treatment and the follow-up period. The RTOG grade between the dressed and undressed area were compared to illustrate the therapeutic effect of CSMed® dressing. RESULTS The results showed that CSMed® dressed area had significant lower RTOG score at 3-7 weeks and final record during the treatment, and 1-3 weeks during follow-up than undressed area. CONCLUSIONS This indicated that CSMed® can delay the onset, reduce the severity, and enhance healing of radiation dermatitis. CSMed® can be used for prophylaxis and management of radiation dermatitis.

Abstract
Plastics have found widespread use in the fields of cosmetic, engineering, and medical sciences due to their wide-ranging mechanical and physical properties, as well as suitability in biomedical applications. However, in the light of the environmental cost of further upscaling current methods of synthesizing many plastics, work has recently focused on the manufacture of these polymers using biological methods (often bacterial fermentation), which brings with them the advantages of both low temperature synthesis and a reduced reliance on potentially toxic and non-eco-friendly compounds. This can be seen as a boon in the biomaterials industry, where there is a need for highly bespoke, biocompatible, processable polymers with unique biological properties, for the regeneration and replacement of a large number of tissue types, following disease. However, barriers still remain to the mass-production of some of these polymers, necessitating new research. This review attempts a critical analysis of the contemporary literature concerning the use of a number of bacteria-derived polymers in the context of biomedical applications, including the biosynthetic pathways and organisms involved, as well as the challenges surrounding their mass production. This review will also consider the unique properties of these bacteria-derived polymers, contributing to bioactivity, including antibacterial properties, oxygen permittivity, and properties pertaining to cell adhesion, proliferation, and differentiation. Finally, the review will select notable examples in literature to indicate future directions, should the aforementioned barriers be addressed, as well as improvements to current bacterial fermentation methods that could help to address these barriers.

Abstract
Film wound dressings represent one of the options in wound therapy. Various polymers can be used for their production. Currently, research focuses on materials of natural origin, more friendly to the human body, which are in many cases able to participate actively in the wound healing process. These include polyamino acids of bacterial origin, substances that are biodegradable, non-toxic, and have a great potential for an application not only in the medical field. From the point of view of film wound dressing formulation, poly-γ-glutamic acid (PGA), as a film-forming agent, and poly-ε-lysine (PL), characterized by antimicrobial activity, are of interest from this group. Therefore, the aim of our experiment was to prepare films consisting of PGA or a combination of PGA and PL with the addition of different plasticizers. The films were prepared by solvent evaporation method and then evaluated for their organoleptic (appearance, colour, transparency, ease of handling), physicochemical (thickness, density, opacity, surface pH), and mechanical properties (tensile strength and tear resistance). As a result, films showing mutual compatibility between the two polymers were obtained, with satisfactory properties for wound application.

Boesenbergia rotunda extract accelerates human keratinocyte proliferation through activating ERK1/2 and PI3K/Akt kinases. Biomed Pharmacother 2021; 133:111002.

Abstract
Boesenbergia rotunda (BR) has long been used as tradition medicine. For its pharmacological effects on wound healing, previous studies in an animal model provided convincing results that the ethanolic extract from the rhizome of this plant can stimulate wound healing. However, the mechanism about how this plant promotes wound healing at the molecular level has not been elucidated. As a step towards the development of wound healing agents, our current study utilized a human keratinocyte cell line (HaCaT) as an in vitro model to define the potential molecular mechanisms of BR extract in enhancing wound-healing. Our HPLC results showed that BR extract contained kaempferol as one of its potential compounds. The extract strongly promoted wound healing of HaCaT cell monolayer. This effect was eventually defined to be regulated through the ability of BR extract to induce cell proliferation. At the signaling level, we discovered that BR extract rapidly activated ERK1/2 and Akt phosphorylation upon the addition of the extract. Additionally, our experiments where specific inhibitors of MEK (U0126) and PI3K (LY294002) were utilized verified that BR enhanced cell proliferation and wound healing through stimulating the MAPK and PI3K/Akt signal transduction pathways. Moreover, direct inhibition of keratinocyte DNA synthesis by mitomycin C (MMC) could completely block the proliferative effects of BR extract. Nevertheless, data from Transwell migration assay revealed that BR extract did not promote keratinocyte migration. Altogether, we provided more evidence that BR possesses its wound healing-promoting action through the activation of proliferation and survival pathways, and our study suggests that BR is an interesting candidate to be developed as a wound healing-promoting agent.

Abstract
PURPOSE Functional weight-bearing mobilization may improve repair of Achilles tendon rupture (ATR), but the underlying mechanisms and outcome were unknown. We hypothesized that functional weight-bearing mobilization by means of increased metabolism could improve both early and long-term healing. METHODS In this prospective randomized controlled trial, patients with acute ATR were randomized to either direct post-operative functional weight-bearing mobilization (n = 27) in an orthosis or to non-weight-bearing (n = 29) plaster cast immobilization. During the first two post-operative weeks, 15°-30° of plantar flexion was allowed and encouraged in the functional weight-bearing mobilization group. At 2 weeks, patients in the non-weight-bearing cast immobilization group received a stiff orthosis, while the functional weight-bearing mobilization group continued with increased range of motion. At 6 weeks, all patients discontinued immobilization. At 2 weeks, healing metabolites and markers of procollagen type I (PINP) and III (PIIINP) were examined using microdialysis. At 6 and 12 months, functional outcome using heel-rise test was assessed. RESULTS Healing tendons of both groups exhibited increased levels of metabolites glutamate, lactate, pyruvate, and of PIIINP (all p < 0.05). Patients in functional weight-bearing mobilization group demonstrated significantly higher concentrations of glutamate compared to the non-weight-bearing cast immobilization group (p = 0.045).The upregulated glutamate levels were significantly correlated with the concentrations of PINP (r = 0.5, p = 0.002) as well as with improved functional outcome at 6 months (r = 0.4; p = 0.014). Heel-rise tests at 6 and 12 months did not display any differences between the two groups. CONCLUSIONS Functional weight-bearing mobilization enhanced the early healing response of ATR. In addition, early ankle range of motion was improved without the risk of Achilles tendon elongation and without altering long-term functional outcome. The relationship between functional weight-bearing mobilization-induced upregulation of glutamate and enhanced healing suggests novel opportunities to optimize post-operative rehabilitation.

Abstract
Tylosema esculentum (morama) is a highly valued traditional food and source of medicine for the San and other indigenous populations that inhabit the arid to semi-arid parts of Southern Africa. Morama beans are a rich source of phenolic acids, flavonoids, certain fatty acids, non-essential amino acids, certain phytosterols, tannins and minerals. The plant's tuber contains griffonilide, behenic acid and starch. Concoctions of extracts from morama bean, tuber and other local plants are frequently used to treat diarrhoea and digestive disorders by the San and other indigenous populations. Information on composition and bioactivity of phytochemical components of T. esculentum suggests that the polyphenol-rich extracts of the bean testae and cotyledons have great potential as sources of chemicals that inhibit infectious microorganisms (viral, bacterial and fungal, including drug-resistant strains), offer protection against certain non-communicable diseases and promote wound healing and gut health. The potential antinutritional properties of a few morama components are also highlighted. More research is necessary to reveal the full prophylactic and therapeutic potential of the plant against diseases of the current century. Research on domestication and conservation of the plant offers new hope for sustainable utilisation of the plant.
