愈合期不同光照强度对黄瓜嫁接苗的影响

研究愈合期不同光照强度对黄瓜嫁接苗定植前质量的影响,旨在为黄瓜嫁接愈合光照的精确化调控提供参考依据。试验将嫁接愈合分为1~3 d、4~6 d、7~10 d 3个时段,分别给予6种不同光照强度梯度处理。结果表明,愈合期在45-90-135μmol·m^-2·s^-1的光照强度梯度下嫁接苗地上部与地下部形态生长显著提升,形态综合指标最佳,较传统愈合条件(0-30-45μmol·m^-2·s^-1)下可溶性糖与可溶性蛋白含量分别提升了65.87%、15.85%,叶绿素荧光参数也表现最优。综合分析表明,45-90-135μmol·m^-2·s^-1的光照强度梯度最有利于黄瓜嫁接苗生长,最有利于嫁接苗可溶性糖和可溶性蛋白的积累,且叶片的光合电子传递效率、光合效率和自我保护调节机制较好,可作为黄瓜嫁接愈合期的光照强度条件,这为提升黄瓜嫁接苗的商品质量提供了一些理论依据。

The impact of seasonal colour change in planting on patients with psychotic disorders using biosensors

The beneficial effect of nature on patients with mental disorders is of particular importance. There has been an increase in mental illnesses in recent years, but research on the design of healing gardens for mental and behavioural disorders remains limited. This paper is part of a wider study that aims to investigate the effect of selected design elements of healing gardens on patients with mental disorders. This study examines the effect of seasonal colour change in plantings in the design of healing gardens on patients suffering from psychotic disorders by using a questionnaire survey and by recording and analysing human behaviour. Images depicting seasonal colour change in different plantings were viewed on a computer monitor by patients. Patients’ behaviour was studied using biosensors for eye-tracking, facial expression analysis and galvanic skin response. The results showed that differences in gender and age between participants did not affect their preferences. However, it appeared to be more difficult to positively affect the emotions of male participants compared to female participants. Seasonal colour change in a tree canopy created positive and intense emotions in the patients. Based on the results, the use of deciduous trees is proposed in the design of healing gardens for patients with psychotic disorders to create seasonal colour change. Further research is necessary to obtain more detailed design recommendations for landscape architects.     

Platelet-Rich Plasma as an Adjunctive Therapy for the Management of a Severe Chronic Distal Limb Wound in a Foal

Distal limb wounds are frequent in horses after traumatic events. The use of platelet-rich plasma (PRP) represents a simple method of treating wounds in equines. A case of a chronic severely contaminated distal limb wound in an 8-month-old foal is presented. The patient was managed with the combination of standard wound therapy (debridement and bandages), surgery, and PRP obtained by a manual tube protocol. No complications were observed with the PRP treatment, and the foal was fully recovered 2 months later. The results from this case report indicate that PRP and its by-products (platelet-poor plasma) could be used as an adjunctive treatment in severe distal limb wounds in horses. A clinical controlled study should be performed to test this hypothesis.     

Outdoor environments in healthcare settings: A quality evaluation tool for use in designing healthcare gardens

This article presents the first outline of a quality evaluation tool (QET) to be used in the process of designing outdoor environments in healthcare settings, e.g. healthcare gardens. Theory triangulation is used to integrate theories and evidence from selected research on people's health/well-being and the outdoor environment. The results first present the theoretical principles underlying the tool and justifying its practical construction. Then, 19 environmental qualities constituting the backbone of the practical tool are presented, including six qualities based on the need to be comfortable in the outdoor environment and 13 qualities based on the need for access to nature and surrounding life. Furthermore, this work presents suggestions of how the tool might include concepts dealing with how users can become involved in the design process, as well as general design guidelines corresponding to the various needs and wishes users may have. The paper ends with a discussion that, among other things, relates the QET to evidence-based design, salutogenesis and pathogenesis.     

The antimicrobial activity of honey against common equine wound bacterial isolates

Delayed healing associated with distal limb wounds is a particular problem in equine clinical practice. Recent studies in human beings and other species have demonstrated the beneficial wound healing properties of honey, and medical grade honey dressings are available commercially in equine practice. Equine clinicians are reported to source other non-medical grade honeys for the same purpose. This study aimed to assess the antimicrobial activity of a number of honey types against common equine wound bacterial pathogens. Twenty-nine honey products were sourced, including gamma-irradiated and non-irradiated commercial medical grade honeys, supermarket honeys, and honeys from local beekeepers. To exclude contaminated honeys from the project, all honeys were cultured aerobically for evidence of bacterial contamination. Aerobic bacteria or fungi were recovered from 18 products. The antimicrobial activity of the remaining 11 products was assessed against 10 wound bacteria, recovered from the wounds of horses, including methicillin resistant Staphylococcus aureus and Pseudomonas aeruginosa. Eight products were effective against all 10 bacterial isolates at concentrations varying from <2% to 16% (v/v). Overall, the Scottish Heather Honey was the best performing product, and inhibited the growth of all 10 bacterial isolates at concentrations ranging from <2% to 6% (v/v).Although Manuka has been the most studied honey to date, other sources may have valuable antimicrobial properties. Since some honeys were found to be contaminated with aerobic bacteria or fungi, non-sterile honeys may not be suitable for wound treatment. Further assessment of gamma-irradiated honeys from the best performing honeys would be useful.     

Application of Platelet-Rich Gel to Enhance Wound Healing in the Horse: A Case Report

A large torn wound of the dorsal elbow region was observed in a 17-year-old Arabian mare. Surgical reconstruction was performed with the horse in standing sedation, but suture dehiscence occurred 2 days later. Autologous platelet-rich gel (PRG) was then applied to the wound every 3 weeks for a total of 3 administrations to accelerate good-quality healing. The wound had healed rapidly and completely within 5 months of the first PRG treatment, without chronic effects or formation of exuberant tissue granulation and with minimum scarring. This case report suggests that topical treatment with autologous PRG, as additional therapy, might be considered beneficial in the management of large-wound healing in horses, and it can be regarded as safe and inexpensive treatment that can be used in field.
