Clinical characteristics and repositioning efficacy analysis of posterior canal-benign paroxysmal positional vertigo-canalolithiasis and vertigo-cupulolithiasis patients.

Background: Currently, there is a ‌paucity of research‌ comparing the clinical characteristics and repositioning efficacy between ‌posterior canal-benign paroxysmal positional vertigo-canalolithiasis (PC-BPPV-ca)‌ and ‌posterior canal-benign paroxysmal positional vertigo-cupulolithiasis (PC-BPPV-cu)‌.

Aims/objectives: To observe the clinical characteristics and compare the efficacy of repositioning maneuvers between PC-BPPV-ca and PC-BPPV-cu patients.

Material And Methods: Clinical information of patients was collected.

Assessing genomic diversity and signatures of selection in Qingyuan Wapiti.

Red deer is a species of family Cervidae that is widely distributed in the world and is often raised to provide antlers, as a trophy or traditional medicine materials, and meat. Currently, the whole genomic data for red deer are very limited. Qingyuan Wapiti (QYW), China's first breed of red deer by artificial breeding, is well known for its high yield of antlers and large body size.

Characterising the change rule of freshness and inorganic anions in reconstituted tobacco pulp with oscillation time.

In order to study the change rule of freshness and acid ions in reconstituted tobacco slurry, the content changes of 17 organic acids and 5 inorganic anions in reconstituted tobacco slurry with different residence times under confined condition were determined by on-line solid-phase extraction ion chromatography in this study. The results showed that the changes of acetic acid, nitrate ion and isovaleric acid in different reconstituted tobacco slurries with oscillation time were regular and consistent, and the trends of the changes of acetic acid, nitrate ion and isovaleric acid in different reconstituted tobacco slurries with oscillation time were correlated with each other in a highly significant way. Taking the evaluation of olfactory aroma and sensory quality qualities of reconstituted tobacco pulps with different residence times as a benchmark, it was found that the variation patterns of nitrate ions and isovaleric acid in reconstituted tobacco pulps with oscillation time were consistent with the variation patterns of olfactory and sensory qualities in the process of closed oscillation; compared with the fresh pulp, the olfactory aroma and sensory qualities of tobacco pulps had unpleasant odours appearing when the content of nitrate ions was reduced by about 48%.

Correlation between obesity and Alzheimers disease and the mechanisms.

Alzheimer's disease (AD) is a progressive central neurodegenerative disorder with an insidious onset. With global aging, the incidence and mortality of AD have been steadily increasing, yet effective treatments remain elusive. Obesity, characterized by excessive or abnormal fat accumulation, is a complex metabolic disorder and a confirmed risk factor for numerous diseases.

Childhood obesity and central precocious puberty.

Central precocious puberty (CPP) is an endocrine disorder in children caused by the early activation of the hypothalamic-pituitary-gonadal axis (HPGA), leading to elevated gonadotropin-releasing hormone (GnRH), which triggers the development of gonads and the secretion of sex hormones. This eventually results in the development of internal and external genitalia and secondary sexual characteristics. CPP significantly affects the physical and mental health of children and may increase the risk of various adult diseases.
