GROUND REACTION FORCES DURING THE GOLF SWING USING DIFFERENT GOLF CLUBS IN FEMALE GOLFERS

The purpose of this study was to investigate effects of different golf clubs on the ground reaction forces during the golf swing for females. Ten right-handed female varsity golfers voluntarily participated in this study. Using three different clubs, they hit the ball by their own swing in four conditions (full driver shot, controlled driver shot, 6-iron shot, and approach-wedge shot). Their motion was three-dimensionally captured which was performed with one foot on each force plate. There were no significant differences in the peak resultant forces between the golf clubs, but the peak resultant horizontal force differed between the golf clubs. The female golfers’ resultant reaction force patterns were classified into three patterns, indicating that the golfers generated the reaction forces in their own ways, which would reflect the characteristics of their golf swing

Use of Balloon Enteroscopy in Preoperative Diagnosis of Neurofibromatosis-Associated Gastrointestinal Stromal Tumours of the Small Bowel: A Case Report

Neurofibromatosis type I (NF1) is one of the most common inheritable disorders and is associated with an increased risk of gastrointestinal stromal tumours (GISTs). However, the predominant location of these lesions in the small bowel makes them difficult to diagnose. We report the successful use of balloon enteroscopy in conjunction with conventional methods for clinical diagnosis of jejunal GISTs in a 70-year-old man with NF1 who presented with melaena. The importance of screening NF1 patients for GISTs and the complementary role of balloon enteroscopy with capsule endoscopy in such diagnoses is discussed

Ground reaction forces during the full driver shot of a Japanese male professional golfer : a case study

J-GLOBAL ID : 201801009314123820J-GLOBAL ID : 201801006075322255J-GLOBAL ID : 200901004400734279J-GLOBAL ID : 200901081100961987J-GLOBAL ID : 202101004237845144We examined the characteristics of ground reaction forces (GRFs) during the full driver shot of an individual Japanese male professional golfer. In addition to the Japanese male professional golfer, a male collegiate amateur golfer participated in this study. By comparing the GRFs during the backswing and downswing with two golfers, we found that the professional golfer exhibited a transfer of loading from the rear leg to the front leg during the downswing, resulting production of higher peak vertical GRF in the front leg (1.51 N/BW). This finding may provide valuable insights into the magnitude and timing of force for golfers seeking to increase the distance of driver shots in golf practice.1520860078898546048application/pdfdepartmental bulletin pape

Cloning of a cDNA encoding a putative metal-transporting P-type ATPase from Arabidopsis thaliana1The nucleotide sequence data reported in this paper will appear in the DDBJ/EMBL/GenBank databases under the accession number D89981.1

AbstractMetal-transporting P-type ATPases were recently proposed to constitute a newly emerged sub-family of cation-transporting P-type ATPases, and are known to occur widely in prokaryotes and eukaryotes. However, no instance has been reported for higher plants. A cDNA clone encoding a metal-transporting P-type ATPase was thus searched for, if present, and was identified in Arabidopsis thaliana. The amino acid sequence, predicted from the determined nucleotide sequence for the cloned cDNA, shows all the critical features common to known metal-transporting P-type ATPases. This plant P-type ATPase has a typical metal-binding motif at its N-terminal portion. The newly isolated Arabidopsis gene, named PAA1, provides us with the first instance of putative metal-transporting P-type ATPases in higher plants. Some results of genomic analyses for this gene are also presented

Time-dependent effects of castration on the bladder function and histological changes in the bladder and blood vessels

We examined the effect of androgens on bladder blood flow (BBF), bladder function and histological changes in castrated male rats. Male Wistar rats were classified into unoperated group (control group), groups castrated at the age of 8 weeks (group 8wPC) and groups castrated at the age of 4 weeks (group 4wPC). Each rat was used at the age of 20 weeks. BBF was measured using fluorescent microspheres. Bladder cystometry was performed without anesthesia or restraint; the bladder was first irrigated with saline and then with 0.25% acetic acid (AA) solution. Maximum voiding pressure and voiding interval were measured. The bladder and iliac artery were histologically examined for differences in smooth muscle and quantity of collagen fiber to analyze the effect of castration on the smooth muscle content. No differences were noted in BBF following castration. The voiding intervals for all groups were shortened (P < 0.001) following AA irrigation. No significant difference was noted in the maximum voiding pressure. Histological changes were observed in bladder and iliac artery. Smooth muscle/collagen ratio at the bladder was lower in groups 8wPC and 4wPC compared to the control group (P< 0.01), while that at the iliac artery was decreased in group 4wPC compared to the control group (P< 0.001). In conclusion, our findings indicate that castration does not alter BBF, but leads to histological changes in the bladder as well as its associated blood vessels

Subaru/FOCAS IFU revealed the metallicity gradient of a local extremely metal-poor galaxy

We present the first measurement of the metallicity gradient in extremely metal-poor galaxies (EMPGs). With Subaru/Faint Object Camera And Spectrograph (FOCAS) Integral Field Unit (IFU), we have observed a nearby, low-mass EMPG, HSC J1631+4426, whose oxygen abundance and stellar mass are known to be 12+log(O/H) $=6.9$ and $\log_{10}(M_*/{\rm M}_\odot)=5.8$, respectively. The measured metallicity gradient is $-0.36 \pm 0.04$ dex kpc$^{-1}$ corresponding to $-0.049 \pm 0.006$ dex R$_\mathrm{e}^{-1}$ for the continuum effective radius of $R_\mathrm{e} = 0.14$ kpc. Our observation has successfully demonstrated that three-dimensional spectroscopy with 8m-class telescopes is powerful enough to reveal the metallicity distribution in local EMPGs, providing precious information of the baryon cycle in local analogs of primordial galaxies in the early Universe.Comment: PASJ accepted, 7 pages, 4 figure
