The First Description Of Germ Tube Fusion Body In Germinating Basidiospores Of Exobasidium Vexans

Germ tube fusion body (GFB) is known to allow for anastomosis between contacting germ tubes in germinating urediniospores of rust fungi in the genus PUCCINIA (Wang and McCallum, 2009)

QUANTITATIVE EVALATION OF DEXTERITY BY MODELING OF JOINT TORQUE

The aim of this study is to quantitatively evaluate the stretch reflex on athletic motions. In this study, we regard stretch reflex as an index of dexterity because dexterous motions effectively utilize the stretch reflex by relaxing the stiffness of articulations. Subjects were one skilled and one unskilled. They performed power clean that is a typical strength training motion. We measured trajectories of joints by using the motion capture system, numerically filtered, differentiated, and calculated the articulation torques. In order to evaluate the strength of stretch reflex, we employ a time series curve fitting method in the proposed torque model that includes a term caused by stretch reflex. The results indicate that the skilleds’ strength of stretch reflex shows large value, compared to the unskilled’s one. This suggests that the proposed torque model and the analytic method allow us to quantitatively measure dexterity

Focus Issue on Male Infertility

Male infertility problems can occur when sperms are limited in number or function. In this paper, we describe the clinical evaluation of male infertility. A detailed history, physical examination, and basic semen analysis are required. In addition, ultrasound, karyotyping, and hormonal studies are needed to determine specific causes of infertility. In addition, the World Health Organization (WHO, 2009) has developed a manual to provide guidance in performing a comprehensive semen analysis. Among the possible reasons for male infertility, nonobstructive azoospermia is the least treatable, because few or no mature sperm may be produced. In many cases, men with nonobstructive azoospermia typically have small-volume testes and elevated FSH. Although treatment may not completely restore the quality of semen from men with subnormal fertility, in some cases a successful pregnancy can still be achieved through assisted reproductive technology

First report of pteridocolous discomycetes, Lachnum lanariceps and L. oncospermatum, on decayed tree fern in Bukit Bendera (Penang Hill), Pulau Pinang, Malaysia

Bukit Bendera is 833 m above sea level and situated in the Northern part of Penang Island, Malaysia. Generally an average temperature is between 20 to 27°C, which is about 5°C cooler than at the sea level. The hill dipterocarp forest dominates Bukit Bendera and tree fern scatteredly grows at higher altitude. Two Lachnum spp. were observed as pteridocolous cup fungi on decayed rachides of several tree fern species, Cyathea contaminans, C. latebrosa, and C. hymenodes. Lachnum oncospermatum is characterized by a wrinkled apothecium and branched stipe. The hairs contain brown colored resinous materials and are finely granulated. Lachnum lanariceps is characterized by a central and cylindrical stipe and hairs containing pale yellow pigment with red or garnet resinous matter. These two Lachnum species are new to Malaysia

A CONSIDERATION OF QUANTITATIVE EVALUATION OF DEXTERITY IN SPORTS EXERCISE

The aim of this study was to quantitatively evaluate dexterity on athletic motions. Subjects were three skilled and three non-skilled weight lifters. They performed power clean that is a strength-training motion. We measured trajectories of joints by using motion capture system, and calculated joint torque according to dynamical equations using only kinematic data. In order to evaluate the strength of stretch reflex and that of proprioceptive feedbacks, we employed curve fitting with the recursive least squares method in our proposed torque model that includes a term caused by stretch reflex and feedback terms with respect to the COP and COM position. The results show that the calculated coefficients reflect some dexterous behavior of skilled motions

Two new species of Exobasidium causing Exobasidium diseases on Vaccinium spp. in Japan

Abstract Two new Exobasidium species on Vaccinium spp. in Japan are described and discussed. Exobasidium kishianum, which causes Exobasidium leaf blight on I/. hirtum var. pubescens and V. smallii, is characterized by its ellipsoid to ovoid basidiospores with (0-)1-3 septa. Its systemic infection is also observed. Exobasidium inconspicuum, cansing Exobasidium leaf blister on V. hirtum vat. pubescens, is characterized by its obovoid or ellipsoid to oval basidiospores with 0-4 septa. Mode of germination of the basidiospores is by germ tube in both species
