To determine the prevalence of osteopenia (OPe) and osteoporosis (OP) in an urban adult population in Malaysia, and to compare the change in the prevalence when using a Caucasian compared to an Asian reference range.

A cross-sectional random sample of the population aged between 45 and 90 years from the state of Selangor, Malaysia, was invited to attend a bone health check-up. Participants with diseases known to affect bone metabolism or who were on treatment for OP were excluded. Bone mineral density was measured using dual energy X-ray absorptiometry. Based on the World Health Organization definitions, the prevalence of OPe and OP was calculated using the Asian and Caucasian T-scores.

A total of 342 subjects (222 females, 120 males), with a mean age of 59.68 (standard deviation 8.89) years, who fulfilled the study criteria were assessed. Based on the Asian reference range, there were 140 (40.9%) subjects with OPe and 48 (14.0%) with OP. On applying the Caucasian reference range, there were 152 (44.4%) subjects with OPe and 79 (23.1%) with OP, with significant increases in males, females, and Chinese ethnic groups. Overall, 75 (21.9%) of subjects had a change in their diagnostic status. T-scores were consistently lower when the Caucasian reference range was used.

In a healthy urban Malaysian population, the prevalence of OP is 14.0% and OPe is 40.9%. Application of a Caucasian reference range significantly increased the number of subjects with OP and may potentially lead to over-treatment.

Virtually all basic cellular research, clinical research and epidemiologic research rely on statistical concepts and methodology for inference. This paper discusses common issues and suggested solutions concerning the application of statistical thinking in bone research, particularly in clinical and epidemiological investigations. The issues are sample size estimation, biases and confounders, analysis of longitudinal data, categorization of continuous data, selection of significant variables, over-fitting, P-values, false positive finding, confidence interval, and Bayesian inference. It is hoped that by adopting the suggested measures the scientific quality of bone research can improve.The hippocampus has been firmly established as playing a crucial role in flexible navigation. Recent evidence suggests that dorsal striatum may also play an important role in such goal-directed behaviour in both rodents and humans. Across recent studies, activity in the caudate nucleus has been linked to forward planning and adaptation to changes in the environment. In particular, several human neuroimaging studies have found the caudate nucleus tracks information traditionally associated with that by the hippocampus. In this brief review, we examine this evidence and argue the dorsal striatum encodes the transition structure of the environment during flexible, goal-directed behaviour. learn more We highlight that future research should explore the following (1) Investigate neural responses during spatial navigation via a biophysically plausible framework explained by reinforcement learning models and (2) Observe the interaction between cortical areas and both the dorsal striatum and hippocampus during flexible navigation.Catalpa bungei is an important resource of timber, belonging to the genus catalpa (Bignoniaceae). In this study, we sequenced complete chloroplast (cp) genome of C. bungei, using a NovaSeq 6000 sequencing platform. The genome of the C. bungei was 152,153 bp in length, including a large single-copy region (84,910 bp), a small single-copy region (12,664 bp), and two inverted repeats regions (30,285 bp). It encodes 126 genes, including 81 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analyses were performed based on 15 cp genomes using the maximum likelihood (ML) method, supported that C. bungei was probably more closely related to C. speciosa. This study, the cp genome of C. bungei was assembled, which will provide more theoretical basis for determine the phylogenetic relationships of the Catalpa and related species.The complete mitochondrial genome of Lysmata amboinensis was obtained and described in this study. This complete mitochondrial genome is 16,735 bp in length and consists of 13 protein-coding genes (PCGs), 2 ribosomal RNA genes (rRNA), and 22 transfer RNA genes (tRNA). A total of 23 genes were encoded by the heavy strand. The overall base composition of the heavy-strand was 31.68% A, 14.31% G, 21.65% C, and 32.36% T, with a high A + T content of 64.05%. The phylogenetic analysis suggested that hippolytidae shrimp may be considered as the polyphyletic taxon. These results are useful for understanding the phylogenetic relationships and evolution of Hippolytidae shrimp.Stellaria dichotoma var. lanceolata Bunge. is a traditional Chinese medicinal plant of Caryophyllaceae, which contains many chemicals, such as β-carboline alkaloids, sterols, cyclic peptides, phenolic acids, and flavonoids and so on, which was used as folk medicines for antifebrile to treat fever and to inhibit the cell growth, cyclooxygenase, and also can anti-inflammatory, anti-allergic, vasodilator, and other effects. Illumina paired-end reads data were used to assemble the complete chloroplast (cp) genome. 16,898,032 raw paired-end reads and the length distribution in 150,602 bp, including a large single-copy (LSC) region of 81,844 bp, a small single-copy (SSC) region of 17,022 bp and a pair of inverted repeats (IRs) of 25,868 bp. Besides, nine protein-coding genes (PCGs) genes and six tRNA genes possess a single intron, while clpP and ycf3 have a couple of introns. Based on the concatenated coding sequences of cp PCGs, the phylogenetic analysis showed that S. dichotoma and Pseudostellaria palibiniana (MK309611) are closely related to each other within the family Caryophyllaceae.
