The purpose of this study was to determine if there were any reliable predictors for achieving jogging requirements after anterior cruciate ligament (ACL) reconstruction. We analyzed associations among variables collected from 128 subjects at 12 weeks postoperatively, including jogging parameters (i.e. pain, apprehension, speed, and distance), the isokinetic muscle strength of the leg extensors, the knee stability, and patient's profiles (i.e. age, sex, activity level, body mass index (BMI), meniscectomy, and cartilage injury).Jogging parameters were significantly correlated with the isokinetic muscle strength of leg extensors, but not with the knee stability. With the jogging ability of achieving a distance of 2000m at a velicity of 9km/h being an objective variable, a logistic regression analysis revealed that the isokinetic muscle strength of leg extensors and BMI were considered relevant. Using a receiver operating characteristic (ROC) curve analysis and a contingency table, the cut-off values of the isokinetic muscle strength of leg extensors to the uninvolved side and body weight were 85% and 1.9Nm/kg, respectively, whose sensitivity and specificity were 0.90 and 0.82, respectively. Therefore, we concluded that the isokinetic muscle strength of leg extensors is a reliable predictor for projecting the timing to start jogging after ACL reconstruction.

Recently, a long-term health concern has been identified in young Japanese women. These women have a high percentage of body fat despite a normal shape index indicator such as BMI. This condition is called marked obesity, and shows relative low lean body mass. Using an analogous determination, we investigated low percentage of muscle quantity (LM) in the extremities of young Japanese women (n=156) . The cross-sectional areas of muscle, subcutaneous fat, and bone were measured in the upper arm and thigh using ultrasonography. Extremity shape index (CSAt/L) was defined as the total extremity cross-sectional area (CSAt) divided by the length of the limb (L), Percent muscle in each extremity (% MA) was calculated from the ratio of muscle CSA to whole limb CSA. LM was defined as the percentage of muscle in the upper arm or thigh less than 1 SD below average and the limb shape index less than 1 SD above average. Nine of 91 subjects displayed LM for the upper arm. A similar proportion of subjects showed LM for the thigh (15/156) . The muscle mass and strength in the upper arm or thigh were compared between the subjects with LM and non-LM subjects with a similar shape index of extremity. There was a tendency towards lower muscle mass and muscle strength in the subjects with LM. From the same comparison, the subjects with LM showed a greater load on extremity muscles to sustain the body weight (i.e., body weight per unit of upper arm or thigh muscle CSA) . To mitigate the deleterious health consequences of low percent muscle quantity it is recommended that young Japanese women who display such a condition should participate in a resistance-training program.

AIMTo confirm the stability of exogenous genes in the generation of transgenic chickens using ejaculated chicken sperm, the deoxyribonuclease (DNase) activity was evaluated in the seminal plasma of ejaculated semen and the stability of DNA was examined by adding lipofection reagents.
METHODSA PCR fragment (249 bp) of pEGFPN-1 vector was used as the DNA substrate and was incubated with the seminal plasma at 40 degree C for 30 min. Then, the whole reaction solution was subjected to agarose gel electrophoresis and the DNA size was evaluated under UV light.
RESULTSThe DNA substrate was completely diminished after incubation with seminal plasma. However, the substrate was intact after incubation with heat-treated seminal plasma or incubation with seminal plasma in the presence of 0.5 mmol/L approximately 5 mmol/L EDTA. The substrate was stabilized in the seminal plasma by the addition of commercially available lipofection reagents.
CONCLUSIONThe DNase activity is present in the seminal plasma of ejaculated chicken semen. However, DNA is stable in the liposomal-DNA complex.

We have previously reported that the thoracolumbar posterior nerve root shows a tortuous epidural course, based on studies of human fetuses near term. For comparison with the cervical nerve, examinations were conducted using frontal, sagittal and horizontal sections of cervical vertebrae from 22 fetuses at 30–38 weeks of gestation. The cervical nerve root showed a short, straight and lateral course near the zygapophysial joint. Multiple rather than single bundles of the cervical posterior root seemed to account for the majority of sensory nerve fibers innervating the upper extremity. Fasciculation of rootlets was evident near the thoracolumbar spinal cord, whereas it was seen in the dural pocket at the nerve exit from the dural sac although both sites were subdural. As in the thoracolumbar region, the nerve sheath was continuous with the dura mater and independently surrounded each of the anterior and posterior roots. Radicular arteries were few in the cervical region. In 2 of the 22 fetuses (31 weeks and 33 weeks), there was a segmental, unilateral abnormality of nerve rootlet fasciculation where the dorsal root ganglion was located lateral or peripheral to the intervertebral region. Long nerve roots running inferiorly are a necessary adaptation to the delayed and marked growth of the thoracolumbar vertebral column.In children, the cervical nerve roots are likely to be affected by movement or dislocation of the vertebrae. The segmental abnormality of the cervical nerve root may be linked to rare variations in the brachial plexus.

BACKGROUND/AIMS: To compare the diagnostic yield of 20-gauge forward-bevel core biopsy needle (CBN) and 22-gauge needle for endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) of solid pancreatic masses. METHODS: The use of 20-gauge CBN was prospectively evaluated for 50 patients who underwent EUS-FNA from June 2016 to December 2016. Data were compared with those obtained by a retrospective study of 50 consecutive patients who underwent EUS-FNA using standard 22-gauge needles between December 2016 and April 2017. At least two punctures were performed for each patient; the sample from the first pass was used for cytology with or without histology and that from the second pass was used for histology. Sample quantity was evaluated using the sample obtained from the second pass. RESULTS: There was no significant difference in the diagnostic accuracy rate between the first and second passes (20-gauge CBN: 96% [48/50]; standard 22-gauge needle: 88% [44/50]). Samples >10× power fields in length were obtained from 90% (43/48) and 60% (30/50) of patients using the 20-gauge CBN and standard 22-gauge needle, respectively (p=0.01). Technical failure occurred for two patients with the 20-gauge CBN. CONCLUSIONS: Diagnostic accuracy of the 20-gauge CBN was comparable to that of the 22-gauge needle. However, two passes with the 20-gauge CBN yielded a correct diagnosis for 100% of patients when technically feasible. Moreover, the 20-gauge CBN yielded core tissue for 90% patients, which was a performance superior to that of the 22-gauge needle.

We investigated the actual condition of patients treated by acupuncture and moxibution in Ibaragi Prefecture.
Subjects were 1823 patients (846 men, 977 women) under the treatment of 14 acupuncture clinics in September to November, 1985.
We prepared the evaluated list that consisted of 11 levels of activities of daily life and 8 degrees of pain.
In every treatment, we wrote down the patient's clinical progress in relation with the list.
The following results were obtained
1. There were many patients in thier forties and fifties.
2. There were many patients who received only one treatment.
3. The chief complaints were low back pains (509 patients), shoulder discomfort (273) knee joint pain (132), etc.
4. Most of the patients could still go on with thier daily lives in spite of the pains.
5. The effects of treatment were rated as follows; better 69.5%, no change 23.9%, worse 5.9%.

Premenstrual syndrome (PMS) that occur during late luteal phase is a problem for many female athletes. Many studies reported that subjective condition is affected by PMS in female athletes. Moreover, female athletes with PMS have higher stress and/or anxiety levels during luteal phase compared with non-PMS athletes. However, the relationship between PMS and physical performance in female athletes are not clarified yet. The purpose of this study was to investigate the relationship between premenstrual syndrome (PMS) and jump performance in female track and field athletes. Sixteen participants who has natural basal body temperature pattern with the menstrual cycle (observed low-temperature and high-temperature phase), were participated in this study. PMS was assessed by ACOG’s premenstrual syndrome questionnaire. As physical performance, counter movement jump (CMJ) and rebound jump (RJ) were evaluated in low-temperature phase and high-temperature phase. The result of this study, no significant differences were observed in body composition and physical performance between low-temperature phase and high-temperature phase. However, compared with participants who had non-symptom, participants who had a breast tenderness of PMS showed larger decreases in jump height of CMJ (p = 0.038) and RJ index (p = 0.015) in high-temperature phase. Therefore, PMS may have a negative effect on physical performance during high-temperature phase in female athletes.

BACKGROUND:
Age-related low-grade inflammation causing endothelial disruption influences sarcopenia, hypertension, and atherosclerosis. We reported previously that maintenance of muscle strength in elderly hypertensive men with high platelet levels is positively associated with subclinical atherosclerosis but not in those with low platelet levels. Since reduced tongue pressure is related to sarcopenia, tongue pressure may be associated with subclinical carotid atherosclerosis in hypertensive elderly subjects, and platelet levels may function as an indicator of the association between tongue pressure and subclinical carotid atherosclerosis.
METHODS:
We conducted a cross-sectional study of 342 hypertensive elderly Japanese men aged 60-89 who participated in an annual health check-up in 2015 and 2016. Subclinical carotid atherosclerosis was defined as a common carotid intima-media thickness (CIMT) of 1.1 mm or more.
RESULTS:
In the overall study population, 171 subjects demonstrated low platelets (< 21.4 × 10/μL). Tongue pressure was significantly inversely associated with subclinical carotid atherosclerosis in these subjects, but not in subjects with high platelets. The known cardiovascular risk factor adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of subclinical carotid atherosclerosis for a 1 standard deviation (SD) increment in tongue pressure (10.4 kPa) were 0.54 (0.35, 0.85) and 1.31 (0.87, 1.96), respectively.
CONCLUSION
Tongue pressure is inversely associated with subclinical carotid atherosclerosis in hypertensive elderly men with low platelet levels, but not in those with high levels. This finding may thus constitute an efficient tool for clarifying the background mechanism of age-related diseases such as sarcopenia, hypertension, and atherosclerosis.
