A comprehensive practical review of acupoint embedding as a semi-permanent acupuncture: A mini review.

Since ancient times, acupuncture has been utilized in the treatment of lots of diseases, as a part of Traditional Chinese Medicine. Acupoint embedding (AEM) therapy, known as catgut embedding, is a development of acupuncture that consists of inserting catgut or surgical threads into specific acupoints to produce continuous acupoint stimulation based on the theory of Traditional Chinese Medicine. The remaining thread in the acupoint works as a semi-permanent acupuncture needle that results in decreasing the total time of the treatment which is required for continuous manual acupuncture sessions and increasing the treatment efficacy and patients' satisfaction. In each session of AEM about twenty 1 to 2 cm-long threads-natural origin, synthetic polymer, or bioactive threads-will be inserted at the target acupoints and this process will be repeated every 3 to 4 weeks. Indications of AEM are somehow similar to manual acupuncture including obesity, pain, musculoskeletal inflammations, infertility, etc, and it cannot be performed on pregnant women and pediatrics. AEM demonstrates its therapeutic effects via modulating immune system function, alleviating body inflammatory conditions, affecting the neurohormonal system, and other mechanisms. Subcutaneous indurations, redness, bleeding, hematoma, and bruising are some adverse events reported following the AEM. In conclusion, the scientific literature suggests that AEM is a relatively safe and convenient therapy if performed by a professional skilled practitioner.

Comparative efficacy of acupuncture, venesection, and physical therapy on chronic low back pain outcomes: a randomized clinical trial.

Objective: Chronic low back pain (CLBP) imposes considerable financial and social burden with poor response to medical and surgical treatments. Alternatively, acupuncture and venesection(Fasd) are traditionally used to alleviate nociceptive and musculoskeletal pains. This study aimed to evaluate the effectiveness and the safety of acupuncture and venesection on CLBP and patient functionality. Methods: The current study was a single-blinded, randomized clinical trial with balanced allocation, conducted in the Department of Physical Medicine & Rehabilitation Medicine, in 2022. One hundred five CLBP patients who had no back pain-attributable structural or major diseases were randomly allocated into three parallel arms and received either physical therapy (PTG), acupuncture (APG), or venesection (VSG). Pain severity and functional aspects were evaluated using the visual analogue scale (VAS) and Oswestry disability index (ODI) during the study. VAS and ODI scores were defined as the primary outcomes. Results: Ninety-five patients were reviewed in the final analysis (PTG=33, APG=30, VSG=31). Demographic data showed equal group distribution. Statistical analysis showed all procedures had reduced VAS score immediately after the first session, after the last session, and after follow-up; however, APG and VSG values were significantly lower (P<0.05). Pain reduction results in follow-up period were more sustainable in APG and VSG as compared to PTG (P<0.01). ODI results revealed global improvement after the last session of the treatment in all groups, while APG had more significant results (P<0.05). During the follow-up period, ODI still tended to decrease in VSG, non-significantly increased in APG, and significantly increased in PTG. Only two patients reported fainting after receiving venesection. Conclusion: Considering the pain and functional scores, both acupuncture and venesection can reproduce reliable results. Acupuncture and venesection both have sustained effects on pain and daily function of the patients even after treatment termination, while physical therapy had more relapse in pain and functional limitations.

Metal Electrocatalysts for Hydrogen Production in Water Splitting.

The rising demand for fossil fuels and the resulting pollution have raised environmental concerns about energy production. Undoubtedly, hydrogen is the best candidate for producing clean and sustainable energy now and in the future. Water splitting is a promising and efficient process for hydrogen production, where catalysts play a key role in the hydrogen evolution reaction (HER). HER electrocatalysis can be well performed by Pt with a low overpotential close to zero and a Tafel slope of about 30 mV dec-1. However, the main challenge in expanding the hydrogen production process is using efficient and inexpensive catalysts. Due to electrocatalytic activity and electrochemical stability, transition metal compounds are the best options for HER electrocatalysts. This study will focus on analyzing the current situation and recent advances in the design and development of nanostructured electrocatalysts for noble and non-noble metals in HER electrocatalysis. In general, strategies including doping, crystallization control, structural engineering, carbon nanomaterials, and increasing active sites by changing morphology are helpful to improve HER performance. Finally, the challenges and future perspectives in designing functional and stable electrocatalysts for HER in efficient hydrogen production from water-splitting electrolysis will be described.

Enhanced CO2 capture potential of UiO-66-NH2 synthesized by sonochemical method: experimental findings and performance evaluation.

The excessive release of greenhouse gases, especially carbon dioxide (CO2) pollution, has resulted in significant environmental problems all over the world. CO2 capture technologies offer a very effective means of combating global warming, climate change, and promoting sustainable economic growth. In this work, UiO-66-NH2 was synthesized by the novel sonochemical method in only one hour. This material was characterized through PXRD, FT-IR, FE-SEM, EDX, BET, and TGA methods. The CO2 capture potential of the presented material was investigated through the analysis of gas isotherms under varying pressure conditions, encompassing both low and high-pressure regions. Remarkably, this adsorbent manifested a notable augmentation in CO2 adsorption capacity (3.2 mmol/g), achieving an approximate enhancement of 0.9 mmol/g, when compared to conventional solvothermal techniques (2.3 mmol/g) at 25 °C and 1 bar. To accurately represent the experimental findings, three isotherm, and kinetic models were used to fit the experimental data in which the Langmuir model and the Elovich model exhibited the best fit with R2 values of 0.999 and 0.981, respectively. Isosteric heat evaluation showed values higher than 80 kJ/mol which indicates chemisorption between the adsorbent surface and the adsorbate. Furthermore, the selectivity of the adsorbent was examined using the Ideal Adsorbed Solution Theory (IAST), which showed a high value of 202 towards CO2 adsorption under simulated flue gas conditions. To evaluate the durability and performance of the material over consecutive adsorption-desorption processes, cyclic tests were conducted. Interestingly, these tests demonstrated only 0.6 mmol/g capacity decrease for sonochemical UiO-66-NH2 throughout 8 consecutive cycles.

Similarities and differences between kaiy in Persian medicine and moxibustion in Chinese medicine.

Kaiy (medieval cautery) is an ancient method of heat therapy in traditional Persian medicine (TPM). Some of its important applications have been neglected during the medical revolution. Meanwhile, different treatment modalities that incorporate heat, including moxibustion, have progressed in traditional Chinese medicine. In this study, we reviewed the main TPM textbooks that were written specifically in the field of kaiy. We considered the traditional teachings in the context of contemporary information, gathered from the scientific literature about moxibustion and modern cauterization. Some surgical therapeutic indications of kaiy (e.g., debridement and coagulative procedures) have been advanced by the innovation of electro-cauterization. However, those therapeutic applications that were based on the TPM humoral theory for relieving body coldness or myofascial pains-which are similar to moxibustion usages-have not received the same attention. Apart from the broad similarities of kaiy and moxibustion as thermal therapies with similar indications, there is a striking correspondence between kaiy point mapping and acupoints. Therefore, further research on different kaiy aspects is recommended. Please cite this article as: Jaladat AM, Alizadeh Vaghasloo M, Atarzadeh F, Ayati MH, Kazemi AH, Akin E, Hashempur MH.

Effectiveness of acupuncture for fatigue in patients with relapsing-remitting multiple sclerosis: a randomized controlled trial.

BACKGROUND: Fatigue is experienced by more than 65% of individuals with multiple sclerosis (MS). Some studies have supported the effectiveness of acupuncture in improving the symptoms of MS. OBJECTIVE: The present research was intended to investigate the effectiveness of acupuncture plus amantadine compared with amantadine alone on fatigue in patients with relapsing-remitting MS (RRMS) in the remission stage of the disease. METHODS: In this randomized controlled trial, 60 participants with RRMS suffering from fatigue were recruited and randomized equally to acupuncture (n = 30) and control (n = 30) groups. The acupuncture group received treatment 2 to 3 times per week for 10 sessions over 4 weeks. Both the acupuncture and control groups received amantadine 100 mg daily and routine treatment with immuno-modulators. The primary outcome was the fatigue severity scale (FSS) score, which was evaluated at baseline, and after 2 and 4 weeks. The secondary outcome was the Multiple Sclerosis Quality of Life 54 (MSQOL-54) questionnaire score, measured at baseline and the end of the 4-week treatment period. RESULTS: The severity of fatigue was reduced in both groups. However, after 4 weeks of treatment, the reduction of fatigue in the acupuncture group was more significant than in the control group (P < 0.01, mean difference (MD) = -1.14, 95% confidence interval (CI): -1.83 to -0.45). Quality of life, including mental and physical status, was significantly improved in the acupuncture group compared with the control group (P < 0.05, MD = 9.09, 95% CI: 0.46 to 17.73). No adverse events occurred in any of the participants. CONCLUSIONS: Acupuncture combined with amantadine and routine care compared with amantadine and routine care alone appears to be an effective short-term treatment for reducing fatigue and enhancing quality of life, including physical function and mental status, in patients with RRMS.

Acupuncture or cupping plus standard care versus standard care in moderate to severe COVID-19 patients: An assessor-blinded, randomized, controlled trial.

Background: Non-pharmacological strategies that have been proposed by complementary medical systems, can be effective in management of COVID-19. Methods: This study was designed as a three-arm, assessor-blinded, randomized controlled trial. A total of 139 hospitalized COVID-19 patients were randomly assigned into three groups: (1) acupuncture (ACUG), (2) cupping (CUPG), and (3) control (CTRG). All participants received conventional treatment. The primary study endpoint included changes in respiratory signs including oxygen saturation (SpO2) and respiratory rate (RR). The secondary endpoints were COVID-19-related hospitalization duration and serious adverse events such as intensive care unit (ICU) admission, intubation or death, all up to day 30. Also, improvements in cough, dyspnea, chest tightness, oxygen demand, anorexia, headache, weakness, sore throat, and myalgia were evaluated. Results: Forty-two patients in ACUG, 44 patients in CUPG, and 42 patients in CTRG completed the trial. After 3 days, SpO2 and RR improved significantly in CUPG and ACUG compared with CTRG (effect size: 8.49 (6.4 to 10.57) and 8.51 (6.67 to 10.34), respectively: p<0.001). Compared with CTRG, patients in CUPG and ACUG recovered faster (mean difference: 6.58 (4.8 to 8.35) and 9.16 (7.16 to 11.15), respectively) and except for two patients in ACUG who were admitted to ICU, none of patients in ACUG or CUPG needed ICU or intubation (p<0.001 in comparison to CTRG). Amelioration of clinical COVID-19 related symptoms reached a high level of statistical significance in CUPG and ACUG in comparison with CTRG (p<0.01). Conclusion: Cupping and acupuncture are promising safe and effective therapies in management of COVID-19. Trial registration: This study was registered at Iranian Registry of Clinical Trials: IRCT20201127049504N1 (https://en.irct.ir/trial/52621).

Warm Cupping of the Posterior Thorax in Combination with Standard Conventional Therapy for ARDS in COVID-19 Patients in ICU: a Case Series.

Acute respiratory distress syndrome (ARDS) is commonly found in critically ill patients with coronavirus disease 2019 (COVID-19). As a non-pharmacological treatment of complementary and alternative medicine (CAM), cupping has been clinically used for respiratory symptoms. We sequentially identified a series of patients with COVID-19 with ARDS who were admitted to the intensive care unit (ICU). Warm cupping of the posterior thorax was performed for seven days. We collected longitudinal severity scores on cough, breathlessness, chest tightness, type of oxygen therapy, and oxygen saturation (SpO2). We hereby report the changes in the severity scores in a series of eight patients who received 21 sessions of cupping in addition to conventional treatments. All patients reported improvement in symptom scores that was matched by an increase in SpO2 by as much as 3.16%. All patients were discharged and did not require the use of a mechanical ventilator. The results suggest that combining cupping with conventional treatment may provide a good prognosis for patients with COVID-19 with ARDS.

Comparison of therapeutic effects of statins and aloe vera mouthwash on chemotherapy induced oral mucositis.

BACKGROUND: Chemotherapy induced oral mucositis is a common problem among patients with cancer. Different therapeutic agents have been evaluated to prevent or treat the disease. Here we aimed to compare therapeutic effects of atorvastatin and aloe vera mouthwash on chemotherapy induced oral mucositis. METHODS: 120 patients with large intestine and gastric cancer who were treated with 5-fluorouracil (FOLFOX4) for the first time were entered and randomized into 3 groups. Group 1 received tablets of atorvastatin 10 mg daily until 2 weeks after chemotherapy sessions plus placebo mouthwash. Group 2 received aloe vera mouthwash plus placebo tablets and group 3 received placebo mouthwash and placebo tablets until 2 weeks after chemotherapy sessions. Severity of mucositis was assessed using world health organization (WHO) indexes. Based on this method, mucositis is divided into 4 grades. This study was approved by Iranian Registry of Clinical Trials (IRCT) with the code of: IRCT20201203049585N1 (https://fa.irct.ir/trial/54037). RESULTS: Analysis of the incidence of mucositis among patients showed that in placebo group, 50% of patients experienced grade 2 to 4 mucositis. In group 1, 9 patients (22.5%) had grade 2 mucositis and 6 patients (15%) had grade 3 mucositis and 4 patients (10%) had grade 4 mucositis. In group 2, only 1 patient (2.5%) was diagnosed with grade 2 mucositis. These data showed no significant differences between group 1 and group 3 (P=0.674), but the therapeutic results of group 2 were significantly better than those of group 3 (P=0.042) and group 1 (P=0.036). CONCLUSION: We showed that treatments with aloe vera mouthwash could be an effective choice in prevention of mucositis for patients undergoing chemotherapy. There are also much to discover about effects of aloe vera mouthwash on this disease.

The Effect of Quercetin Nanosuspension on Prostate Cancer Cell Line LNCaP via Hedgehog Signaling Pathway.

BACKGROUND: Prostate cancer (PCa) is the second leading cause of cancer death in American population. In this manner, novel therapeutic approaches for identification of therapeutic targets for PCa has significant clinical implications. Quercetin is a potent cancer therapeutic agent and dietary antioxidant present in fruit and vegetables. METHODS: To investigate the underlying mechanism by which the PCa was regulated, nanoparticles of quercetin were administrated to cells. For in vitro experiments, human PCa cell line LNCaP were involved. Cell viability assay and quantitative RT-PCR (qRT-PCR) for hedgehog signaling pathway genes were used to determine the key signaling pathway regulated for PCa progression. RESULTS: The cell viability gradually decreased with increased concentration of quercetin nanoparticles. At 48 h, 40 mM concentration of quercetin treatment showed near 50% of viable cells. Quercetin nanoparticles upregulates Su(Fu) mRNA expressions and downregulates gli mRNA expressions in the LNCaP cells. CONCLUSION: The results showed that the hedgehog signaling targeted inhibition may have important implications of PCa therapeutics. Additionally, the outcomes provided new mechanistic basis for further examination of quercetin nanoparticles to discover potential treatment strategies and new targets for PCa inhibition.

Ultrafast tunable integrated Faraday isolator based on optical pumping in a graphene-InSb-graphene structure.

We have designed a new class of single-stage Faraday isolators that employs two sheets of graphene. Using nonreciprocal optical materials such as InSb boosts plasmonic coupling between the graphene layers, which leads to a 45 deg polarization rotation as well as increased transmission through the structure. More than 91% transmission is achieved in the THz band (1 THz-7 THz). This design opens up the way in ultrafast integrated magneto-optical nanophotonic devices to realize single-stage isolators with enhanced transmittance in the THz band.

Tailoring subtractive cell biopanning to identify diffuse gastric adenocarcinoma-associated antigens via human scFv antibodies.

Among various solid tumours, gastric cancer (GC) is one of the leading causes of cancer-related deaths worldwide. Expansion into the peritoneal cavity, which results from dissemination of diffuse cancer cells, is the main cause of mortality in gastric adenocarcinoma patients. Therefore, investigation of putative biomarkers involved in metastasis is prerequisite for GC management. In an effort to discover potential tumour markers associated with peritoneal metastasis of GC, a semi-synthetic human scFv library (Tomlinson I) was used to isolate novel antibody fragments recognizing MKN-45, a poorly differentiated diffuse gastric adenocarcinoma cell line. Four rounds of subtractive selection each consisting of extensive pre-absorption of phage library with NIH-3T3 murine embryonic fibroblasts and AGS (a well-differentiated intestinal gastric adenocarcinoma) cell line were carried out prior to positive selection on MKN-45 target cells. ELISA-based screening of 192 phage-displayed scFv clones indicated 21 high-affinity binders with specific staining of MKN-45 compared with AGS cells. Diversity analysis of the selected phage-scFvs resulted in five distinct sequences with multiple frequency. Further analysis by ELISA and flow cytometry verified three clones that specifically recognized MKN-45 cells. Liquid chromatography-mass spectrometry analysis of the scFv-immunoprecipitated proteins has led to identification of c-Met, HSP90 α and HSP90 ß as candidate biomarkers associated with diffuse GC. Immunohistochemistry revealed the capability of purified scFvs to differentiate diffuse and intestinal gastric adenocarcinoma. Taken together, the isolated MKN-45-specific scFv fragments and their cognate antigens would be beneficial in screening and management as well as targeting and therapy of the diffuse gastric adenocarcinoma.

Effect of four weeks of ocular-motor exercises on dynamic visual acuity and stability limit of female basketball players.

INTRODUCTION: Visual skills are an integral part of most daily activities and an effective indicator of the functional ability of athletes, particularly in the fields of dynamic sports like basketball. Despite the important role of vision and effect of ocular exercises on functional skills in athletes, a few studies have been conducted in this regard. Thus, this study aimed to investigate the effect of ocular-motor exercises on dynamic visual acuity and stability limit of female basketball players. METHODS: In this semi-experimental study 30 club elite female basketball players aged between 18 and 24 years, with at least three years of specialized basketball experience, were randomly assigned to two intervention and control groups. The athletes in the intervention group participated in the designed four-week program (six sessions per week) of the oculo_motor exercises. The control group did just their own daily routine exercises. The limit of stability was measured by the Biodex balance system SD and dynamic visual acuity was measured by the PowerPoint, which is for detecting dynamic visual acuity. Also, the SPSS software version 19 was used to analyze the data by using descriptive statistics methods: independent t and Paired t tests, at a significance level of P ≤ 0.05. RESULTS: The results showed that doing four weeks of the oculo_motor exercises led to a significant increase in the overall stability index (OSI) from 28/66 ±â€¯7/23 to 51/60 ±â€¯6/38 (p = 0.001), as well as in dynamic visual acuity from 29/73 ±â€¯4/19 to 56/20 ±â€¯8/81(p < 0.001); in the intervention group, these changes were also statistically significant in comparison with the control group and before doing the exercise protocol (p < 0.05). CONCLUSION: According to the obtained results, the oculo_motor exercises can be used to enhance the limit of stability and dynamic visual acuity in basketball players and other dynamic sports.

The necessity for integrating traditional, complementary, and alternative medicine into medical education curricula in Iran.

BACKGROUND: The use of traditional and complementary medicine (T&CM) is increasing in both developed and developing countries. The school of Persian medicine (PM) in Iran is a comprehensive medical school that is rich in history and has its own special principles, elements, philosophy, and diagnostic and treatment options. Many complementary therapy modalities are also popular and in demand among patients and physicians. The aim of this paper is to provide logic for the policymakers in Iranian medical education to make changes in medical education curricula, particularly on integrating T&CM. METHODS: We reviewed the global experience in teaching T&CM to medical students, and highlighting the strengths of PM, described why it is necessary to integrate T&CM into general medicine curricula in Iran. RESULTS: PM is a traditional system of medicine that dates back about 7000 years. Although there are few studies about the safety and effectiveness of PM, research into it has recently been accelerated. There is a suitable opportunity for integrating T&CM with conventional medicine. Physicians should be familiar with T&CM to avoid any contraindications, interactions, and unwanted effects. CONCLUSION: Traditional medicine is part of Iran's heritage and, thus, needs special attention. Familiarization of physicians with T&CM can help them choose the best treatment options for their patients. To integrate T&CM into the medical education curricula of Iran, a two-credit course has been proposed for implementation across the country.

Optimization of biomolecule separation by combining microscale filtration and design-of-experiment methods.

There is considerable interest in developing microscale (i.e., high-throughput) methods that enable multiple filtration experiments to be run in parallel with smaller sample amounts and thus reduce the overall required time and associated cost to run the filtration tests. Previous studies to date have focused on simply evaluating the filtration capacity, not the separation performance. In this work, the stirred-well filtration (SWF) method was used in combination with design-of-experiment (DOE) methods to optimize the separation performance for three binary mixtures of bio-molecules: protein-protein, protein-polysaccharide, and protein-DNA. Using the parallel based format of the SWF method, eight constant-flux ultrafiltration experiments were conducted at once to study the effects of stirring conditions, permeate flux, and/or solution conditions (pH, ionic strength). Four separate filtration tests were conducted for each combination of process variables; in total, over 100 separate tests were conducted. The sieving coefficient and selectivity results are presented to match the DOE design format and enable a greater understanding of the effects of the different process variables that were studied. The method described herein can be used to rapidly determine the optimal combination of process factors that give the best separation performance for a range of membrane-based separations applications and thus obviate the need to run a large number of traditional lab-scale tests.

OBJECTIVES: Clonidine is a relative alpha2 agonist that's used as a premedicative drug in anesthesia in recent years. The aim was to asses the effect of oral clonidine as premedicative drug on 24 hours urine output, urine specific gravity, serum and urine electrolyte level and renin plasma activity METHOD: A randomized double blind controlled clinical trial was performed in Asali hospital Khoramabad-Iran during 2004. Sixty patients in ASA class 1 and 2, were randomly selected and divided into two groups. One group received clonidine tablet and control group received placebo tablet, orally, ninety minutes before induction of general anesthesia for cystocel-rectocel perineorraphy surgery. In this study we took blood and urine samples for laboratory measurements before as well as 6 hours after taking the tablets. Differences between two groups were analyzed by students T-test. RESULTS: Significant increase in 24 hours urine output (P = 0.001) was seen in clonidine group, compared to control group. Clonidine group had higher urine electrolyte levels (P < 0.05) however, no differences were seen in blood electrolyte level (P > 0.05). Urine specific gravity was lower in clonidine group (P < 0.05). Significant decrease in plasma renin activity was seen in clonidine group (P = 0.001). CONCLUSION: This study suggested that clonidine is a safe premedication drug in anesthesia and does not change the serum electrolytes level.
