Germination and development of M1 seedlings of two Selliera radicans Cav. accessions subjected to gamma radiation

Selliera radicans is a creeping plant native to Chile, New Zealand and Australia. It is increasingly used in the ornamental industry, and there is interest in breeding it to create commercial varieties. The aim of this study was to determine the effects of different doses of gamma radiation applied to the seeds on the germination and development of seedlings (M1) and the LD50 of two accessions of Selliera radicans for use in the induction of mutations. Seeds of the Vichuquén and La Serena accessions were exposed to 0, 100, 200, 300, 400, 500, 600 and 700 Gy from a 60Co source. Weekly germination percentages along with seedling numbers and lengths were recorded. Vichuquén seeds were more sensitive to this physical agent. The LD50 was 243.9 Gy for Vichuquén and 445.6 Gy for La Serena. Seedling lengths reached almost 4 mm for Vichuquén and 11.3 mm for La Serena at 12 weeks after sowing. Doses lower than 200 Gy are recommended since higher doses do not allow the development of seedlings to the extended cotyledon stage. Highlights: This is the first radiosensitivity study for the Goodeniaceae family and therefore for the Selliera genus. This study shows the specific effect of gamma radiation at the level of germination and seedling formation according to accession of origin. This study could be used for the genetic improvement of Selliera radicans via the induction of mutations.

Efficacy and Effectiveness of Physical Agent Modalities in Complex Regional Pain Syndrome Type I: A Scoping Review

Complex regional pain syndrome type I (CRPS-I) is a rare condition with huge variability in triggering factors and clinical scenarios. The complexity of the pathophysiology of this condition fosters the proposal of several therapeutic options with different mechanisms of action in both research and clinical practice. An interdisciplinary and multimodal approach, including pharmacological and non-pharmacological interventions, particularly physical therapy, is recommended by international guidelines, but the benefits and harms of available interventions are poorly known. In this scoping review, the clinical rationale for use of physical agent modalities for patients with CRPS-I will be presented. We found 10 studies addressing the role of electromagnetic field therapy, electrotherapy, and laser therapy. Our findings suggest that physical therapy modalities, in particular transcutaneous electrical nerve stimulation (TENS) and pulsed electromagnetic field therapy (PEMF), may contribute to reduce pain and improve function in patients with CRPS-1.

STUDI KASUS: PROGRAM FISIOTERAPI PADA CARPAL TUNNEL SYNDROME CASE STUDY: PHYSIOTHERAPY PROGRAMS IN CARPAL TUNNEL SYNDROME

Carpal tunnel syndrome (CTS) adalah kelainan nyeri pada ekstremitas atas yang disebabkan oleh kompresi saraf medianus di terowongan karpal, dengan prevalensi berkisar antara 6,3% hingga 11,7%. Ketika terjadi penekanan nervus akan menyebabkan nyeri, gejala neurologis dan penurunan kemampuan fungsional dan dapat menganggu aktivitas pekerjaan. Pengobatan carpal tunnel syndrome (CTS) dapat dilakukan dengan medikasi dan program fisioterapi. Program fisioterapi bermanfaat untuk menurunkan nyeri, penguatan otot ekstremitas atas dan wrist dan meningkatkan aktivitas fungsional dan mengurangi resiko disabiltias. Tujuan studi ini adalah mengetahui efektivitas program fisioterapi dengan menggunakan ultrasound, nervus dan tendon gliding terhadap peningkatan aktivitas fungsional pada penederita Carpal Tunnel Syndrome (CTS) Kata kunci:Carpal Tunnel Syndrome (CTS), Aktivitas Fungsional, Terapi Latihan, Electro Physical Agent.

Determination of Levels of Exposure to Physical Agent: Equivalent Noise in the Coffee Production Industry

This The present article provides the results of a study on the noise as an industrial agent in a coffee company, during the roasting process, packaging and distribution of the final product. The study is oriented to identify the dangers and risks that are presented in the processes to determine the level to which the workers are exposed with the purpose of establishing preventive protection measures that allow to control the risks. Although the results of this study cannot be generalized, due to its qualitative nature, the proposed study can guide similar studies in other related processes in the coffee industry..

Effects of Physical-Agent Pain Relief Modalities for Fibromyalgia Patients: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Purpose. We conducted a systematic review and meta-analysis to investigate the effects of the following physical-agent modalities for pain relief in fibromyalgia (FM) patients. Methods. We identified randomized controlled studies of adults with FM in the MEDLINE, CINAHL, and PEDro databases. The primary outcome measure was pain relief measured by a visual analogue scale (VAS), and the secondary outcome measures of interest were subjective improvements in the number of tender points, Fibromyalgia Impact Questionnaire (FIQ), and quality of life (QOL) scores. Results. Eleven studies were included in our review. The studies’ physical-agent modalities were low-level laser therapy (LLLT), thermal therapy, electromagnetic field therapy, and transcutaneous electrical nerve stimulation (TENS). LLLT did not reduce VAS scores, but it significantly reduced both the number of tender points and FIQ score. Thermal therapy was associated with significantly reduced VAS scores, tender points, and FIQ scores. Electromagnetic field therapy was associated with significantly reduced VAS score and FIQ score. TENS significantly reduced VAS scores. Conclusion. Our analyses revealed that thermal therapy and LLLT had a partial effect on pain relief in FM patients, and this beneficial effect may have a positive influence on FM patients’ health status.
