Findings from Exploratory Factor Analysis (EFA) support three dimensions of self-efficacy and six dimensions of metacognitive awareness of students toward mathematics reasoning that has been conceptualized. The overall internal consistency reliability of Cronbach Alpha coefficients was above 0.9. Based on the analysis performed, it can be concluded that developed instrument has sufficient evidence of validity and reliability to measure self-efficacy and metacognitive awareness of university students toward mathematics reasoning
Comparison of muscle activity in the empty-can and full-can testing positions using F-18-FDG PET/CT
BACKGROUND:
There has been much controversy over specific tests for diagnosis of supraspinatus tendon tear. The aim of this study was to evaluate the metabolic activity of the deltoid and rotator cuff muscles while maintaining the full-can and empty-can testing positions using 2-deoxy-2-[18 F]fluoro-D-glucose (18 F-FDG) positron emission tomography (PET)/computed tomography (CT).
METHODS:
Ten healthy volunteers without shoulder pain or diabetes mellitus participated in this study. Following FDG injection, both arms were maintained in either the empty-can or full-can position for 10 min. PET/CT was performed 40 min after injection. Maximum standardized uptake values (SUVs) were measured in the deltoid and rotator cuff muscles on axial PET images.
RESULTS:
The middle deltoid exhibited the most significant increase in muscle activity at both testing positions. Additionally, a significant increase in muscle activity was observed in the middle deltoid compared with the supraspinatus (P < 0.05) in the empty-can testing position. SUVs of the middle deltoid, supraspinatus, and subscapularis showed a significant increase in the empty-can testing position compared with the full-can testing position (P < 0.05).
CONCLUSIONS:
Significantly increased activity of the supraspinatus in conjunction with the middle deltoid and subscapularis after empty-can testing may result in decreased specificity of the empty-can test in detecting isolated supraspinatus activity. The full-can test, however, may be used to test the function of the supraspinatus with the least amount of surrounding middle deltoid and subscapularis activity
Factors influencing the attitude of undergraduate students towards mathematical reasoning: An approach using AMOS-structural equation modelling
Studies on mathematics achievement status show that mathematical reasoning in Malaysian education is critical, especially among university students. Students' attitude toward mathematics is affected by affective, behavioural and cognitive factors. The present research investigated the connections between these variables and their impact on individuals' attitudes towards mathematics reasoning. A statistical analysis method, namely, AMOS-Structural Equation Modelling, was used in this approach. The survey method involving 378 university education students around the Klang Valley was selected using a proportional stratified random sampling technique. The respondents must complete the mathematics reasoning assessment and answer the questionnaire consisting of three components: affective, behavioural and cognitive towards mathematics reasoning. AMOS-Structural Equation Modelling (AMOS-SEM) was applied using data obtained from questionnaires. Results demonstrated that the measurement models showed acceptable validity and reliability by removing some indications from the scales. The findings illustrate the relationship between students' attitudes and mathematical reasoning. Moreover, attitude is significantly related to students' mathematical reasoning performance in university education. The next study's recommendation involves an interview session to explore more findings that might impact their learning in mathematical reasoning
Coagulant Effect and Tolerability of Yeast-Produced Recombinant Batroxobin in Healthy Adult Subjects
BACKGROUND AND OBJECTIVE: Batroxobin, a snake venom thrombin-like enzyme, converts fibrinogen into fibrin by cleaving fibrinopeptide A. It is used for hemostasis; however, the supply of native batroxobin is limited. Therefore, we developed a recombinant batroxobin (r-batroxobin) from Pichia pastoris and evaluated its pharmacodynamics and safety in humans.
METHODS: A randomized, double-blind, placebo-controlled, single ascending-dose study was performed. Eight healthy subjects were enrolled in each r-batroxobin dose group (2.5, 5.0, or 10.0 BU/2.0 mL administered intravenously), and randomized to receive r-batroxobin (n = 6) or matching placebo (n = 2). Safety was evaluated during the study, and pharmacodynamics was assessed using prothrombin time (PT), activated partial thromboplastin time (aPTT), thrombin time (TT), and fibrinogen level.
RESULTS: All subjects in each cohort completed the study. No significant changes in PT or aPTT occurred after intravenous r-batroxobin administration. Compared with the placebo group, the fibrinogen level in all r-batroxobin dose groups decreased significantly to 8.68-33.57% from the baseline within 12 h (p ≤ 0.05). The TT in the 5.0 and 10.0 BU/2.0 mL groups significantly increased to 7.53-18.48% from baseline within 12 h compared with that of the placebo group (p ≤ 0.05), whereas that of the 2.5 BU/2.0 mL group exhibited non-significant changes compared with the placebo group. No serious adverse events occurred.
CONCLUSIONS: A single intravenous injection of r-batroxobin within a dose range of 2.5-10.0 BU/2.0 mL was well tolerated and resulted in a significant decrease in fibrinogen and prolongation of TT.

Teaching and Learning Theories Applied in Mathematics Classroom among Primary School Teachers
Mediating Role of Metacognitive Awareness Between Self-Efficacy and Mathematics Reasoning Among Education Undergraduate Students During Pandemic
This research aimed to examine the contribution of metacognitive awareness as a moderator in the relationship between self-efficacy and mathematical reasoning among education undergraduates during the Covid-19 Pandemic. The analysis included 184 undergraduate students in one public university around Klang Valley, Malaysia. The researcher distributes mathematics reasoning assessment, metacognitive awareness, and self-efficacy questionnaires to collect research data. Statistical Package for the Social Sciences version 25 analyzes the mediating influence of metacognitive awareness in the correlation between self-efficacy and mathematics reasoning. The findings revealed that undergraduate mathematics and science education students had better mathematical reasoning abilities than undergraduates of nonmathematics and science education. However, the result indicated that mathematics and science education undergraduate students have high metacognitive awareness and utilize more strategies in mathematics reasoning assessment. This research suggested that further analysis can measure other populations, such as secondary school students’ metacognitive awareness and self-efficacy in mathematics reasoning

A Putative Apoplastic Effector of Clavibacter capsici, ChpGCc as Hypersensitive Response and Virulence (Hrv) Protein in Plants
Clavibacter bacteria use secreted apoplastic effectors, such as putative serine proteases, for virulence in host plants and for hypersensitive response (HR) induction in nonhost plants. Previously, we have shown that Clavibacter capsici ChpGCc is important for the necrosis development in pepper (Capsicum annuum) leaves. Here, we determine the function of ChpGCc, along with three paralogous proteins, for HR induction in the apoplastic space of a nonhost plant, Nicotiana tabacum. The full-length and signal peptide–deleted (ΔSP) mature forms of all proteins fused with the tobacco PR1b signal sequence were generated. The full-length and ΔSP forms of ChpGCc and only the ΔSP forms of ChpECc and Pat-1Cc, but none of the ChpCCc, triggered HR. Based on the predicted protein structures, ChpGCc carries amino acids for a catalytic triad and a disulfide bridge in positions like Pat-1Cm. Substituting these amino acids of ChpGCc with alanine abolished or reduced HR-inducing activity. To determine whether these residues are important for necrosis development in pepper, alanine-substituted chpGCc genes were transformed into the C. capsici PF008ΔpCM1 strain, which lacks the intact chpGCc gene. The strain with any variants failed to restore the necrosis-causing ability. These results suggest that ChpGCc has a dual function as a virulence factor in host plants and an HR elicitor in nonhost plants. Based on our findings and previous results, we propose Clavibacter apoplastic effectors, such as ChpGCc, Pat-1Cm, Chp-7Cs, and ChpGCm, as hypersensitive response and virulence (Hrv) proteins that display phenotypic similarities to the hypersensitive response and pathogenicity (Hrp) proteins found in gram-negative bacteria.
