RESUMO
Background: Accelerated skeletal muscle wasting is a shared trait among many pathologies and aging. Acupuncture has been used as a therapeutic intervention to control pain; however, little is known about its effects on skeletal muscle atrophy and function. The study's purpose was to compare the effects of acupuncture, electro-acupuncture, and electrical stimulation on cast-induced skeletal muscle atrophy. Methods: Forty female Sprague Dawley rats were randomly divided into groups: Control, casted (CAST), CAST+Acupuncture (CAST-A), 4) CAST+Electro-acupuncture (CAST-EA), and CAST+Electrical stimulation (CAST-ES) (n = 8). Plaster casting material was wrapped around the left hind limb. Acupuncture and electro-acupuncture (10 Hz, 6.4 mA) treatments were applied by needling acupoints (stomach-36 and gallbladder-34). Electrical stimulation (10 Hz, 6.4 mA) was conducted by needling the lateral and medial gastrocnemius muscles. Treatments were conducted for 15 min, three times/week for 14 days. Muscle atrophy F-box (MAFbx), muscle RING finger 1 (MuRF1), and contractile properties were assessed. Results: Fourteen days of cast-immobilization decreased muscle fiber CSA by 56% in the CAST group (p = 0.00); whereas, all treatment groups demonstrated greater muscle fiber CSA than the CAST group (p = 0.00). Cast-immobilization increased MAFbx and MuRF1 protein expression in the CAST group (p<0.01) while the CAST-A, CAST-EA, and CAST-ES groups demonstrated lower levels of MAFbx and MuRF1 protein expression (p<0.02) compared to the CAST group. Following fourteen days of cast-immobilization, peak twitch tension did not differ between the CAST-A and CON groups (p = 0.12). Conclusion: Skeletal muscle atrophy, induced by 14 days of cast-immobilization, was significantly attenuated by acupuncture, electro-acupuncture, or electrical stimulation.
RESUMO
BACKGROUND: The main pathophysiologic conditions of erectile dysfunction (ED) after radical prostatectomy are considered to be corporal fibrosis and apoptosis induced by cavernosal nerve (CN) injury. OBJECTIVES: In a rat model of CN crush injury (CNCI), we investigated whether combination treatment with JNK inhibitor (JNKi), SP600125, and HDAC inhibitor (HDACi), suberoylanilide-hydroxamic-7 acid (SAHA), for 2 weeks after CNCI would restore erectile function by suppressing fibrosis and apoptosis through normalization of JNK and HDAC pathways. MATERIALS AND METHODS: Seventy 12-week-old rats were randomly divided into five groups: Sham surgery, CNCI alone, CNCI treated with daily intraperitoneal injection of 10 mg/kg JNKi, CNCI treated with daily oral administration of 25.0 mg/kg HDACi, and CNCI daily treated with a combination. Two weeks after CNCI, we investigated the erectile response to electrostimulation and conducted histological staining, caspase-3 activity assay, and western blot analysis. RESULTS: CNCI alone resulted in significantly reduced intracavernosal pressure/mean arterial pressure (MAP) and area under the curve/MAP, decreased smooth muscle (SM)/collagen ratio and SM content, higher caspase-3 activity, and increased protein levels of total HDAC3, transforming growth factor (TGF)-ß, fibronectin, and c-Jun phosphorylation, compared with the Sham surgery. The CNCI groups exposed to JNKi, HDACi or both showed improvements in erectile-responses and SM/collagen ratio, compared to the CNCI alone. The combined treatment showed additional improvement in erectile responses at 1.0V stimulation and in SM/collagen ratio compared to the single agent treatment. SM content, caspase-3 activity, and c-Jun phosphorylation improved in the two CNCI groups exposed to JNKi. The two CNCI groups exposed to HDACi showed normalization of protein levels of HDAC3, fibronectin, and TGF-ß. DISCUSSION AND CONCLUSIONS: The combined administration of JNKi and HDACi during the acute phase after CNCI in rats can preserve ED by suppressing cavernosal fibrosis and apoptosis by normalizing the HDAC/TGF-ß and JNK pathways.

BACKGROUND: Because of structural alterations in the corpus cavernosum after radical prostatectomy (RP), post-RP erectile dysfunction remains a very difficult condition to treat. We aimed to determine if the combined administration of a Jun-amino terminal kinase (JNK) inhibitor and hepatocyte growth factor (HGF) in the immediate post-injury period would restore erectile function by antiapoptotic and pro-regenerative effects through the rectification of molecular pathways related to the structural integrity of the penis in a rat model of bilateral cavernosal nerve crush injury (CNCI). METHODS: A total of 70 rats were divided into five groups: Sham surgery (S), CNCI (I), and once-daily intraperitoneal administration of 10.0 mg/kg JNK inhibitor + twice-weekly intracavernosal administration of low-dose (2.1 µg), medium-dose (4.2 µg), or high-dose (8.4 µg) HGF (I + J + LH or I + J + MH or I + J + HH, respectively) in the immediate post-injury period. Erectile responses to electrostimulation (1.0, 3.0, and 5.0 V), histological staining, caspase-3 activity, and Western blotting were evaluated 9 days after surgery. RESULTS: Group I showed lower intracavernosal pressure (ICP)/mean arterial pressure (MAP) after stimulation at each voltage, lower area under the curve (AUC)/MAP after stimulation at each voltage, less smooth muscle (SM) content, a lower SM/collagen ratio, higher caspase-3 activity, increased cJun phosphorylation, decreased protein expression of PECAM-1, decreased cMet phosphorylation, and decreased endothelial nitric oxide synthase (eNOS) phosphorylation compared to Group S. The SM content, SM/collagen ratio, protein expression of ICP/MAP, or AUC/MAP after stimulation at each voltage in Group I + J + LH were partially restored, despite the normalization of cJun phosphorylation and caspase-3 activity. The ICP/MAP, AUC/MAP, caspase-3 activity, SM content, protein expression of PECAM-1, cJun phosphorylation, cMet phosphorylation, and eNOS phosphorylation in both Groups I + J + MH and I + J + HH were restored to the levels observed in Group S, while the SM/collagen ratio was significantly improved but not completely normalized. CONCLUSIONS: Our data indicated that the combined administration of a JNK inhibitor and medium or high-dose HGF to nerve-injured rats in the immediate post-injury period after CNCI may restore erectile function to a level comparable to the normal level by suppressing cavernosal apoptosis and preserving the integrity of SM or endothelium via rectification of the cJun and cMet/eNOS pathways.

We determined if combined administration of JNK-inhibitors and HGF (hepatocyte-growth-factor) would restore erectile-function through both antiapoptotic and regenerative effects in a rat model of cavernous-nerve-crush-injury (CNCI), and compared the results with administration of JNK-inhibitor alone or HGF alone. We randomized 70 rats into 5 groups: sham-surgery-group (S), CNCI (I) group, a group treated with once-daily intraperitoneal-administration of 10.0-mg/kg of JNK-inhibitors (J), a twice-weekly intracavernosal-administration of 4.2-µg HGF group (H), and a combined-treatment with 10.0-mg/kg JNK-inhibitors and 4.2-µg HGF group (J+H). We investigated erectile-responses to electrostimulation, histological-staining, caspase-3-activity-assay, and immunoblotting at two-weeks postoperatively. The three treatment groups showed improvements in erectile-responses (ICP/MAP and AUC/MAP ratios) compared to Group-I. The erectile-responses in Group-J+H were greater than those in Group-J or Group-H. The erectile-responses in Group-J+H were generally normalized. Caspase-3-activity and cJun-phosphorylation in Group-J and Group-J+H improved compared to Group-I, whereas caspase-3-activity in Group-H partially improved. Protein-expression of PECAM-1, eNOS-phosphorylation, and smooth-muscle content in Group-J+H were normalized, although those in Group-J or Group-H were partially restored. Combination therapy with JNK-inhibitors and HGF can generally normalize erectile-function through anti-apoptosis and preservation of endothelium or SM in rat CNCI model. The combined treatment appears to be superior to the respective agent alone in terms of therapeutic effects.

Cancer is caused by uncontrolled cell division and is a leading cause of mortality worldwide. Oenothera odorata (O. odorata) extract is used in herbal medicine to inhibit inflammation, but its potential anti-tumor properties have not been fully evaluated. Here, we demonstrated that O. odorata extract inhibits the proliferation of lung adenocarcinoma and melanoma cell lines In Vitro, and also inhibits the growth of melanoma cells In Vivo. After partitioning the extract with n-hexane, chloroform, ethyl acetate, and n-butanol, it was found that the butanol-soluble (OOB) and water-soluble (OOW) fractions of O. odorata extract are effective at inhibiting tumor cell growth In Vivo although OOW is more effective than OOB. Interestingly, these fractions did not inhibit the growth of non-cancerous cells. The anti-proliferative effects of the OOW fraction were found to be mediated by inhibition of glycolysis and cellular respiration. UPLC of both fractions showed two major common peaks, which were predicted to be hydrolyzable tannin-related compounds. Taken together, these data suggest that O. odorata extract has anti-tumor properties, and the molecular mechanism involves metabolic alterations and inhibition of cell proliferation. O. odorata extract therefore holds promise as a novel natural product for the treatment of cancer.

OBJECTIVE: To investigate the immediate effect of horseshoe taping for patellar superior and inferior gliding (HTPSG and HTPIG, respectively) using kinesiology tape on the peak moment of fatigued quadriceps. METHODS: Twenty-eight adults were divided into the HTPSG (experimental) and HTPIG (control) groups. The peak moment of the dominant quadriceps of the participants was measured using Biodex System 4 prior to the experiment and after inducing quadriceps fatigue. The peak moment of the quadriceps was measured after separate application of HTPSG and HTPIG using kinesiology tape. RESULTS: After kinesiology tape application, the peak moment of the quadriceps muscle was significantly increased in both groups (p<.05); however, the peak moment of the fatigued quadriceps muscle was significantly higher in the HTPSG group than in the HTPIG group (p<.05). CONCLUSIONS: The application of HTPSG using kinesiology tape would more be helpful for immediate recovery after exercise-induced quadriceps fatigue.

Rounded shoulder posture (RSP) causes an imbalance of the adjacent joints due to the malalignment of the shoulder joint, and thus affects the strength of the muscles surrounding the shoulder. This study aimed to investigate the effect of rounded shoulder taping (RST) on shoulder posture and muscle strength in junior baseball players. Nineteen junior baseball players participated in the study, which used a crossover design at an interval of 1 week. The participants were randomized to receive rounded shoulder taping (RST) and sham kinesiology taping (SKT) using kinesiology tape. RSP was measured using two 12-inch combination squares, and shoulder peak torques were measured by isokinetic equipment. The results showed that RST led to significant changes in RSP (p < 0.05), but no significant changes were observed with SKT (p < 0.05). RST led to significant changes in the peak torques of external rotation and internal rotation of the shoulder (p < 0.05), but no significant changes were observed with SKT (p < 0.05). These results suggest that RST could help to correct RSP and improve peak torque of external and internal rotation of the shoulders of junior baseball players with RSP.
RESUMO
The objective of this study was to investigate whether ankle balance taping (ABT) applied after muscle fatigue-inducing exercise can cause immediate improvements in dynamic and static balance. A total of 31 adults (16 males and 15 females) met the inclusion criteria. The experiment was designed using a single-blinded, randomized controlled trial. Changes in static and dynamic balance were measured before and after inducing muscle fatigue in the ankles and after ABT or ankle placebo taping (APT). After ankle muscle fatigue-inducing exercise, both the ABT and APT groups showed significant increases in surface area ellipses in the static state with eyes open (p < 0.05), and significant increases in surface area ellipses in the static and dynamic states with eyes closed (both p < 0.05). After taping of the fatigued ankle, surface area ellipses decreased significantly when eyes were open and closed in the static and dynamic states, but only in the ABT group (p < 0.05). Static balance was significantly different between groups (eyes open, 36.2 ± 86; eyes closed, 22.9 ± 46.7). Dynamic balance was significantly different between groups (eyes open, 68.6 ± 152.1; eyes closed, 235.8 ± 317.6). ABT may help prevent ankle injuries in individuals who experience muscle fatigue around the ankles after sports and daily activities.
RESUMO
Sophora flavescens is used as a traditional herbal medicine to modulate inflammatory responses. However, little is known about the impact of (-)-maackiain, a compound derived from S. flavescens, on the activation of inflammasome/caspase-1, a key factor in interleukin-1ß (IL-1ß) processing. Here, we report that (-)-maackiain potently amplified caspase-1 cleavage in macrophages in response to nigericin (Nig). In macrophages primed with either lipopolysaccharide or monophosphoryl lipid A, Nig-mediated caspase-1 cleavage was also markedly promoted by (-)-maackiain. Notably, (-)-maackiain induced the production of vimentin, an essential mediator for the activation of the NOD-, LRR-, and pyrin domain-containing protein 3 inflammasome, thereby contributing to promotion of the formation of the inflammasome complex to activate caspase-1. Taken together, our data suggest that (-)-maackiain exerts an immunostimulatory effect by promoting IL-1ß production via activation of the inflammasome/caspase-1 pathway. Thus, the potent inflammasome-activating effect of (-)-maackiain may be clinically useful as an acute immune-stimulating agent.

The number of kinesiology tape's users is increasing year by year. However, the insufficiency of fundamental knowledge about the appropriate usage of kinesiology tapes can generate undesired side-effects caused by incorrect application of kinesiology tapes and/or denouncement of kinesiology tapes as an ineffective practice. Therefore, it is necessary to arrange a set of general guidelines of kinesiology taping that must be followed. If not, the treatment may have to be ceased due to the side-effects such as skin's troubles. Another problem, which impeaches effectivity of treatment by kinesiology tapes, is focusing solely on the present area of pain or discomfort. However, such solution is only short-termed and the likelihood of reappearance of the pain is remarkably high. Therefore, it is essential to find and eliminate the origin of the problem. If these fundamentals conditions of tape's application are satisfied, the treatment by kinesiology tapes may bring us far more better results.
RESUMO
BACKGROUND: Patellofemoral pain syndrome (PFPS) is one of the most common knee disorders affecting women. OBJECTIVE: The purpose of this study was to investigate the effects of balance taping on PFPS. METHODS: Balance taping using kinesiology tape was applied for 2.5 months (average of 16 h/day) to both knees in a 26-year-old female nurse with bilateral PFPS. RESULTS: The congruence angle decreased in the right and left knees from 30∘ to 5∘ and from 20∘ to 5∘, respectively. The Patient Specific Functional Scale score increased from 17/50 to 50/50, indicating improved functional state of the knees, while the Numeric Pain Rating Scale scores for from sitting to standing, from standing to sitting, and kneeling improved from 6/10 and 0/10, indicating no pain in the knee joints. Application of repeated balance taping for 2.5 months reduced PFPS. CONCLUSION: Considering the outcome of the study, we recommend balance taping as a complementary treatment method for PFPS.

BACKGROUND: Osteoarthritis (OA) is a degenerative disease that not only causes knee pain in older adults, but also has an adverse effect on walking. Therefore, intervention for older patients with OA is important. To investigate the immediate effects of kinesiology taping (KT) on the pain and gait function of the older adults with knee OA. METHODS: This study enrolled 10 older adults individuals living in the community who were diagnosed with knee OA. All participants were assessed for knee pain, walking ability, and balance before and after application of knee KT. Knee pain was assessed in resting and walking conditions using the visual analog scale. Walking and balance were assessed using a 10-m walking test and a timed up and go test. RESULTS: In the present study, KT significantly improved gait and balance with reduction in knee pain during walking than non-KT (Pâ<â.05). CONCLUSIONS: This study demonstrated that knee KT has a positive effect on pain reduction and walking and balance ability of the older adults with OA. Therefore, this study suggests that KT can be used as an intervention to relieve knee pain and aid walking and balance ability in the older adult.

Background and objectives: Shoulder impingement syndrome (SIS) is the most common disorder among people with shoulder pain. The purpose of this case report was to investigate the effect of the combined application of balance taping using kinesiology tape and cross taping on a part-time worker with SIS. Case Report: Combined balance taping and cross taping was applied for 3 weeks (average, 16 hours per day) on a part-time worker with severe pain and a limited range of motion (ROM) in the shoulder who had visual analogue scale (VAS) pain scores of 7 and 8 out of 10 for shoulder flexion and abduction, respectively, and pain and disability scores of the Shoulder Pain Disability Index (SPADI) of 37 out of 50 and 29 out of 80, respectively. After the combined application of balance taping and cross taping, the VAS pain scores for shoulder flexion and abduction decreased from 7 to 0 and from 8 to 0, respectively, and the ROM increased to a normal range. The SPADI pain score decreased from 37 to 2, and the disability score decreased from 29 to 1. Shoulder activity level also increased, and the patient was able to return to his part-time job. Conclusions: We suggest combined application of balance taping and cross taping as an effective treatment for part-time workers with SIS.

Range-wide population studies of wide spread species are often associated with complex diversity patterns resulting from genetically divergent evolutionary significant units (ESUs). The compound evolutionary history creating such a pattern of diversity can be inferred through molecular analyses. Asparagus cochinchinensis, a medicinally important perennial herb, is in decline due to overharvesting in Korea. Eight A. cochinchinensis populations in Korea and three populations from neighboring countries (China, Japan and Taiwan) were examined using nine nuclear microsatellite loci and three chloroplast microsatellite loci to characterize molecular diversity patterns. The average within-population diversity was limited likely due to long-term bottlenecks observed in all eight populations. High pairwise FST values indicated that the populations have largely diverged, but the divergences were not correlated with geographic distances. Clustering analyses revealed a highly complex spatial structure pattern associated with two ESUs. Approximate Bayesian Computation (ABC) suggests that the two ESUs split about 21,000 BP were independently introduced to Korea approximately 1,800 years ago, and admixed in secondary contact zones. The two ESUs found in our study may have different habitat preferences and growth conditions, implying that the two genetically divergent groups should be considered not only for conservation and management but also for breeding programs in agricultural areas.

We aimed to determine whether combination of LIM-kinase 2 inhibitor (LIMK2i) and phosphodiesterase type-5 inhibitor (PDE5i) could restore erectile function through suppressing cavernous fibrosis and improving cavernous apoptosis in a rat model of cavernous nerve crush injury (CNCI). Seventy 12-week-old Sprague-Dawley rats were equally distributed into five groups as follows: (1) sham surgery (Group S), (2) CNCI (Group I), (3) CNCI treated with daily intraperitoneal administration of 10.0 mg kg-1 LIMK2i (Group I + L), (4) daily oral administration of 20.0 mg kg-1 udenafil, PDE5i (Group I + U), and (5) combined administration of 10.0 mg kg-1 LIMK2i and 20.0 mg kg-1 udenafil (Group I + L + U). Rats in Groups I + L, I + U, and I + L + U were treated with respective regimens for 2 weeks after CNCI. At 2 weeks after surgery, erectile response was assessed using electrostimulation. Penile tissues were processed for histological studies and western blot. Group I showed lower intracavernous pressure (ICP)/mean arterial pressure (MAP), lower area under the curve (AUC)/MAP, decreased immunohistochemical staining for alpha-smooth muscle (SM) actin, higher apoptotic index, lower SM/collagen ratio, increased phospho-LIMK2-positive fibroblasts, decreased protein kinase B/endothelial nitric oxide synthase (Akt/eNOS) phosphorylation, increased LIMK2/cofilin phosphorylation, and increased protein expression of fibronectin, compared to Group S. In all three treatment groups, erectile responses, protein expression of fibronectin, and SM/collagen ratio were improved. Group I + L + U showed greater improvement in erectile response than Group I + L. SM content and apoptotic index in Groups I + U and I + L + U were improved compared to those in Group I. However, Group I + L did not show a significant improvement in SM content or apoptotic index. The number of phospho-LIMK2-positive fibroblasts was normalized in Groups I + L and I + L + U, but not in Group I + U. Akt/eNOS phosphorylation was improved in Groups I + U and I + L + U, but not in Group I + L. LIMK2/cofilin phosphorylation was improved in Groups I + L and I + L + U, but not in Group I + U. Our data indicate that combined treatment of LIMK2i and PDE5i immediate after CN injury could improve erectile function by improving cavernous apoptosis or eNOS phosphorylation and suppressing cavernous fibrosis. Rectification of Akt/eNOS and LIMK2/cofilin pathways appears to be involved in their improvement.

This study aimed to determine the effects of application direction of the kinesiology tape on the strength of fatigued quadriceps muscles, and included 15 athletes (mean: age, 19.53 ± 2.42 years; height, 176.93 ± 6.9 cm; weight, 72.87 ± 13.02 kg). The kinesiology tape was randomly applied to the quadriceps from origin to insertion (n = 7) or from insertion to origin (n = 8) after inducing quadriceps muscle fatigue. After 1 week, the kinesiology tape was applied in the opposite direction (insertion to origin [n = 7] or origin to insertion [n = 8]) after inducing quadriceps muscle fatigue. The peak torque of the fatigued quadriceps muscles was measured before and after tape application. Increased peak torque values were observed irrespective of the direction of taping. No significant differences were noted in the peak torque of the fatigued quadriceps muscles with respect to application direction. Kinesiology tape application may improve the strength of fatigued quadriceps muscles regardless of application direction.

Few studies have been performed regarding the reduction of pain in the upper trapezius (UT) muscle by applying interventions to the sternocleidomastoid (SCM) muscle, which is innervated by the same nerves.The purpose of this study was to investigate the effects of soft tissue release intervention on the SCM and suboccipital muscles with regard to muscle hardness and pressure pain threshold (PPT) of the SCM and UT muscles in smartphone users with latent myofascial trigger points (MTrPs) in the UT muscle.Seventeen smartphone users (5 men and 12 women) with latent MTrPs in the UT muscle participated in the study. This study used a single blinding, cross-over design, wherein sternocleidomastoid soft tissue release (SSTR) and suboccipital release (SR) were applied on the subjects in random order one week apart. Muscle hardness and the PPT of the SCM and UT muscles were assessed before and after the intervention.After SSTR was applied, the SCM and UT muscles showed a significant decrease in muscle hardness and a significant increase in PPT. After SR was applied, the UT muscle showed a significant decrease in muscle hardness and a significant increase in PPT. When comparing the amount of change between the SSTR and SR interventions, significant differences were found for SCM muscle hardness and PPT of the UT muscle in the SSTR intervention, compared with the SR intervention.Therefore, we suggest that, to reduce pain in the UT muscle, it may be useful to apply intervention directly to the UT muscle, as well as to the SCM muscle, which is innervated by the same nerve.

ETHNOPHARMACOLOGICAL RELEVANCE: This research describes the ethnomedicinal plants as used by three Chin indigenous groups inhabiting areas at Natma Taung National Park (NTNP) in bio-culturally diverse Myanmar. The aim of this study was (1) to identify wild medicinal species and evaluate their local importance in local peoples' healthcare as well as in protected area conservation; and (2) to compare traditional medicinal plant knowledge among the informants. MATERIALS AND METHODS: A total of 206 Müün, Ng'gah and Daai informants from 20 villages were interviewed using semi-structured questionnaires. Species use-reports were computed to determine plant local importance and the informant consensus factor. Descriptive and the inferential statistics Mann-Whitney U and Kruskal-Wallis tests were employed to evaluate and compare the informants' traditional medicinal knowledge. RESULTS: A total of 75 wild ethnomedicinal taxa in 40 plant families across 16 ICPC-based disease categories were recorded. Species which recorded the highest number of use-reports appeared to play an important role not only in informants' primary healthcare and in park conservation, but also in local livelihood. CONCLUSION: This study presents the diversity of ethnomedicinal plants and their local importance in Chin indigenous peoples' healthcare. This paper also recognizes the value of these plants and the local traditional knowledge for the conservation and management of NTNP.

BACKGROUND: Controversy exists regarding whether the kinesiology tape application direction affects muscle strength. METHODS: Eighteen healthy volunteers (12 men, 6 women) participated. Kinesiology tape was randomly applied to the quadriceps muscles either from origin to insertion or from insertion to origin. A Biodex isokinetic dynamometer was used to measure the peak torque of the quadriceps pre-and post-taping. RESULTS: There was a significant difference in muscle strength after taping, regardless of the kinesiology tape application direction. There were no significant differences in the peak torque of the quadriceps between the 2 kinesiology tape application directions. CONCLUSIONS: The application of kinesiology tape application to the rectus femoris, vastus medialis, and vastus lateralis of the quadriceps increased the muscle torque, regardless of the tape application direction. Therefore, to enhance quadriceps strength, we recommend the application of kinesiology tape to 3 of the muscles of the quadriceps (specifically, the rectus femoris, vastus medialis and vastus lateralis), irrespective of the tape application direction.
