The Emerging Importance of Mitochondria in White Adipocytes: Neither Last nor Least

The growing recognition of mitochondria’s crucial role in the regulation of white adipose tissue remodeling and energy balance underscores its significance. The marked metabolic diversity of mitochondria provides the molecular and cellular foundation for enabling adipose tissue plasticity in response to various metabolic cues. Effective control of mitochondrial function at the cellular level, not only in thermogenic brown and beige adipocytes but also in energy-storing white adipocytes, exerts a profound influence on adipose homeostasis. Furthermore, mitochondria play a pivotal role in intercellular communication within adipose tissue via production of metabolites with signaling properties. A more comprehensive understanding of mitochondrial regulation within white adipocytes will empower the development of targeted and efficacious strategies to enhance adipose function, leading to advancements in overall metabolic health.

Objective:To learn about the status of iodine deficiency disorders in children and pregnant women in coastal areas of Guangxi Zhuang Autonomous Region (Guangxi for short).Methods:From January 2017 to December 2020, 12 counties (cities, districts) in Beihai City, Qinzhou City and Fangchenggang City in coastal areas of Guangxi were selected as the survey sites to carry out iodine deficiency disorders monitoring. Each county (city, district) was divided into five areas according to administrative regions: East, West, South, North and Middle. One township (town) was selected from each area, and 40 non-boarding children aged 8 to 10 (age balanced, half male and half female) and 20 pregnant women were selected from each township (town) as the survey subjects. Edible salt samples and urine samples were collected from children and pregnant women to detect salt iodine and urinary iodine levels; thyroid volume of children was determined and the rate of goiter was calculated.Results:From 2017 to 2020, a total of 8 905 children were monitored, and the median salt iodine of children was 23.4 mg/kg, and the medians salt iodine in each year were 23.7, 22.8, 23.5, 23.6 mg/kg, respectively; the median urinary iodine of children was 164.7 μg/L, and the medians urinary iodine in each year were 161.2, 169.7, 156.0, 171.1 μg/L, respectively; 30 of them had goiter, the rate of goiter of children was 0.34% (30/8 905). A total of 6 626 pregnant women were monitored, and the median salt iodine of pregnant women was 23.5 mg/kg, and the medians salt iodine in each year were 23.7, 22.5, 24.3, 23.8 mg/kg, respectively; the median urinary iodine of pregnant women was 139.6 μg/L, and the medians urinary iodine in each year were 129.6, 131.6, 134.4, 175.0 μg/L, respectively.Conclusions:The iodine nutrition of children in coastal areas of Guangxi is at an appropriate level (100 - 199 μg/L), and the rate of goiter has reached the national iodine deficiency disorders elimination standard (< 5%). But pregnant women are at risk of iodine deficiency (urinary iodine < 150 μg/L).

Aesthetic evaluation of nasolabial angle alteration on the soft tissue profile of skeleton class I / 华西口腔医学杂志

<p><b>OBJECTIVE</b>To study the influence of nasolabial angle alteration on facial profile attractiveness and investigate the perception differences in profile attractiveness among laypeople.</p><p><b>METHODS</b>A young Chinese female with normal hard and soft tissue cephalometric values was chosen as a research object. Profile photograph was taken in a natural head position. Photoshop software was chosen to rotate the nose tip and upper lip, thus changing the degree and direction of nasolabial angle. A total of 33 different profile pictures were achieved. Thirty-three professional orthodontists and 64 non-professionals were chosen to score these 33 pictures.</p><p><b>RESULTS</b>When the upper lip position was fixed, the profile was considerably attractive because the angle of nasal tip was not changed or altered. When the nasal tip rotation angle was fixed, profiles with a retroclined upper lip were considered significantly attractive by the layperson and professional groups. Regardless of the direction of the nasal tip rotation, the respondents considered the profile with a retroclined upper lip highly attractive.</p><p><b>CONCLUSION</b>The soft tissue profile with a retroclined upper lip looks considerably attractive in Chinese female populations. Therefore, during an orthodontic treatment, appropriate retraction of the incisor is recommended to improve soft tissue profile attractiveness.</p>

Identification of miR-23a as a novel microRNA normalizer for relative quantification in human uterine cervical tissues

Quantitative real-time RT-PCR (RT-qPCR) is being widely used in microRNA expression research. However, few reports detailed a robust identification and validation strategy for suitable reference genes for normalisation in microRNA RT-qPCR studies. The aim of this study was to identify the most stable reference gene(s) for quantification of microRNA expression analysis in uterine cervical tissues. A microarray was performed on 6 pairs of uterine cervical tissues to identify the candidate reference genes. The stability of candidate reference genes was assessed by RT-qPCR in 23 pairs of uterine cervical tissues. The identified most stable reference genes were further validated in other cohort of 108 clinical uterine cervical samples: (HR-HPV- normal, n = 21; HR-HPV+ normal, n = 19; cervical intraepithelial neoplasia [CIN], n = 47; cancer, n = 21), and the effects of normalizers on the relative quantity of target miR-424 were assessed. In the array experiment, miR-26a, miR-23a, miR-200c, let-7a, and miR-1979 were identified as candidate reference genes for subsequent validation. MiR-23a was identified as the most reliable reference gene followed by miR-191. The use of miR-23a and miR-191 to normalize expression data enabled detection of a significant deregulation of miR-424 between normal, CIN and cancer tissue. Our results suggested that miR-23a and miR-191 are the optimal reference microRNAs that can be used for normalization in profiling studies of cervical tissues; miR-23a is a novel microRNA normalizer.
