Characterization of Human FSH Isoforms Reveals a Nonglycosylatedβ -Subunit in Addition to the Conventional Glycosylatedβ -Subunit

Abstract: Human FSH consists of a mixture of isoforms that can be separated on the basis of differences in negative charge conferred by variations in the numbers of sialic acid residues that terminate oligosaccharide branches. Western analysis of human FSH isoforms separated by chromatofocusing revealed the presence of two human FSHβ isoforms that differed in size. A low mol wt human FSHβ isoform was associated with all FSH isoform fractions. A high mol wt human FSHβ isoform was associated with the more acidic fractions and increased in relative abundance as the pI decreased. Characterization of representative human FSHβ isoforms by mass spectrometry and automated Edman degradation revealed a low mol wt isoform that was not glycosylated. A high mol wt isoform was N-glycosylated at Asn residues 7 and 24. These results indicate that pituitary human FSH consists of two classes of molecules: those that possess a nonglycosylated β-subunit and those that possess a glycosylated β-subunit. Glycoprotein hormones are known t...

The effects of elastic band resistance training combined with blood flow restriction on strength, total bone‐free lean body mass and muscle thickness in postmenopausal women

Abstract: Summary Introduction Elastic band (EB) training is a common form of resistance training used by the elderly, individuals with joint problems or those recovering from injury. EB training performed at low intensities by these populations may have little effect on muscle hypertrophy. However, when combined with blood flow restriction (BFR), low-intensity EB resistance training may result in muscle hypertrophy. Methods Postmenopausal women (61 ± 5 years) were assigned to a moderate-to-high-intensity EB group (MH, n = 8) or a low-intensity EB group combined with BFR (LI-BFR, n = 6). Each group performed seated chest press, seated row and seated shoulder press with EB three times a week for eight weeks. EB colours progressed in each group by having participants maintain a rating of 7–9 on the OMNI Resistance for active muscle (OMNI-RES AM) scale (0–10) throughout training. In the LI-BFR group, BFR pressure progressed during the first 4 weeks of training (80–120 mmHg), after which EB colours were progressed. Results 1-repetition maximum increased for chest press (P = 0·01), shoulder press (P = 0·02) and seated row (P = 0·01), but no differences were found between groups. Only pectoralis major muscle thickness in the upper body increased (P = 0·04). A trend was found for an increase in total bone-free lean body mass (P = 0·055). Conclusions The main findings of this study were that moderate-to-high-intensity EB training and low-intensity EB training with BFR resulted in similar increases in strength, total bone-free lean body mass and muscle thickness.

Cultural Dimensions of Career Decision-Making Difficulties

Abstract: This study investigated cultural dimensions of career decision-making difficulties using the Career Decision-Making Difficulties Questionnaire. Career decision-making difficulties were compared among White, African, Hispanic, and Asian American high school and university students at U.S. schools. Results indicated Asian American students perceived significantly more difficulties in career decision making than other groups, whereas White American students perceived the fewest difficulties. Asian American students reported more difficulties than White and Hispanic American students before the process and more difficulties than White and African American students during the process. Findings are discussed based on perspectives of cultural differences. Career decision-making difficulty is emerging as an important construct in framing and understanding factors contributing to the career development of adolescents and young adults. Career decision-making difficulty has been linked to several critical career behaviors such as career indecision (Man, 2001; Osipow & Gati, 1998) and career decision-making self-efficacy (Gati, Osipow, Krausz, & Saka, 2000). Just as it is important to understand what constitutes "ideal" career decision-making behaviors and attitudes, it is also important to understand the characteristics of "problematic" decision-making attitudes and behaviors that may lead to difficulties in career development. Gati, Krausz, and Osipow (1996) classified career decision-making difficulties into three major clusters: (a) lack of readiness, which occurs before the decision-making process; (b) lack of information, which occurs during the decision-making process; and (c) inconsistent information, which also occurs during the decision-making process. These clusters are, in turn, subdivided. The first cluster, lack of readiness, includes three categories of difficulties: (a) lack of motivation to engage in the career decision-making process; (b) general indecisiveness concerning all types of decisions; and (c) dysfunctional beliefs, including irrational expectations. The second cluster, lack of information, includes four categories of difficulties: (a) lack of knowledge about the steps involved in the process, (b) lack of information about self, (c) lack of information about various career alternatives, and (d) lack of information about ways of obtaining additional information. The third cluster of difficulties, inconsistent information, involves (a) unreliable information, (b) internal conflicts, and (c) external conflicts. A total of 10 categories thus constitute the taxonomy of career decision-making difficulties. Researchers examining the constructs and validity of this taxonomy have found empirical support in a variety of populations, such as clients versus nonclients (Gati et al., 2000), people taking Internet-based versus paper-and-pencil career assessments (Gati & Saka, 2001), cross-national comparisons (Gati et al., 1996; Mau, 2001), and high school (Gati & Saka, 2001; Leung & Hou, 2002) and university students (Osipow & Gati, 1998). Although the validity of the career decision-making difficulty taxonomy has received wide support, its cultural implications and relevancy remain relatively unexamined. It is well documented that cultural-contextual factors have a strong influence on individuals' career behaviors and outcomes. Blustein and Ellis (2000) argued that one of the challenges for career assessment in the 21st century is the need to affirm cultural diversity. Increasing globalization and cultural diversity in the workforce necessitate that career assessment be relevant for all cultural groups (Fouad & Zao, 2000). Reviews of career assessment tools suggest that very little has been done to examine applicability of career assessment to cultural minorities (Leong & Hartung, 2000; Leong & Leung, 1994). Lcong and Hartung (2000) have indicated that studies focusing on cross-cultural career assessment have tended to focus on the cultural validity of existing instruments, which have been based predominantly on Western models of test construction. …

Approximation by spherical waves inL p -spaces

Abstract: The paper is devoted to the following problem. Consider the set of all radial functions with centers at the points of a closed surface inRn. Are such functions complete in the spaceLq(Rn)? It is shown that the answer is positive if and only ifq is not less than 2n/(n + 1). A similar question is also answered for Riemannian symmetric spaces of rank 1. Relations of this problem with the wave and heat equations are also discussed.
