Associations between extreme temperature exposure and hypertensive disorders in pregnancy: a systematic review and meta-analysis

Yanxia Mao, Qian Gao, Ying Zhang, Yan Yue, Tiechao Ruan, Yi Yang, Tao Xiong

Summary: This article systematically assesses the association between extreme temperature exposure and hypertensive disorders in pregnancy (HDP). The study found that heat exposure in the first half of pregnancy increases the risk of developing preeclampsia or eclampsia, while cold exposure decreases the risk. This indicates the importance of temperature regulation in HDP management.

Expression of NEDD4L and ENaC in Urinary Extracellular Vesicles in Pre-eclampsia

P. Y. M. Leung, M. Katerelos, S. Choy, N. Cook, M. Lee, K. Paizis, A. Abboud, J. A. Manning, P. F. Mount, D. A. Power

Summary: This study assessed the expression changes of renal epithelial sodium channel (ENaC) and ubiquitin ligase NEDD4L in urinary extracellular vesicles (UEV) of pre-eclamptic women compared to normal pregnant controls. UEV were separated and NEDD4L, α-ENaC, and γ-ENaC were identified. There was no difference in NEDD4L and α-ENaC expression, but pre-eclamptic subjects showed increased expression of γ-ENaC.

Endothelial-dependent relaxation of α-pinene and two metabolites, myrtenol and verbenol, in isolated murine blood vessels

L. Jin, Z. Xie, P. Lorkiewicz, S. Srivastava, A. Bhatnagar, D. J. Conklin

Summary: The metabolism and vascular effects of alpha-pinene, a biogenic volatile organic compound emitted by plants, were studied. The metabolites of alpha-pinene, myrtenol and verbenol, were found to have beneficial cardiovascular effects by relaxing blood vessels. Additionally, alpha-pinene activated the TRPA1 channel, which also had cardiovascular implications.

Public perceptions of air pollution and its impacts on fertility desire: a nationwide study in China

Xing Bang He, Kui Zhou, Jamal Hussain, Rizwan Akhtar

Summary: In recent years, there has been an increasing focus on air pollution and its effects on human health. However, the impact of air pollution on people's desire to have children is still uncertain. This study utilizes a theoretical model and data analysis to explore the connection between the perception of air pollution and fertility desire. The findings suggest that individuals who consider air pollution a significant issue are less likely to have more than one child. The study concludes that raising awareness of environmental issues and implementing effective policies are crucial in addressing this problem.

Post-acute exercise cardiovagal modulation in older male adults with and without type 2 diabetes

Joao Luis Maroco, Ines Arrais, Tiago Silvestre, Marco Pinto, Sergio Laranjo, Joao Magalhaes, Helena Santa-Clara, Bo Fernhall, Xavier Melo

Summary: This study examined the effects of acute high-intensity interval exercise and moderate continuous exercise on heart rate variability and baroreflex sensitivity in older adults with and without type 2 diabetes mellitus (T2DM). The results showed that high-intensity interval exercise reduced cardiac vagal modulation in adults without T2DM, but not in older adults with T2DM. This suggests the presence of cardiac autonomic impairments in older adults with T2DM.

Summary: This study suggests that PVAT undergoes biological remodeling in response to elevated blood pressure, while adventitia undergoes remodeling mainly in the early stage of hypertension.

The Prospective Natural History Study of Patients with Intractable Venous Malformation and Klippel-Trenaunay Syndrome to Guide Designing a Proof-of-Concept Clinical Trial for Novel Therapeutic Intervention

Akihiro Fujino, Kanako Kuniyeda, Taiki Nozaki, Michio Ozeki, Tetsuji Ohyama, Iori Sato, Kiyoko Kamibeppu, Akira Tanaka, Naoto Uemura, Kazuhiro Kanmuri, Kenji Nakamura, Fumiaki Kobayashi, Souichi Suenobu, Tadashi Nomura, Ayato Hayashi, Munetomo Nagao, Aiko Kato, Noriko Aramaki-Hattori, Kotaro Imagawa, Kosuke Ishikawa, Junko Ochi, Saya Horiuchi, Hiroshi Nagabukuro

Summary: This study followed the clinical course of 34 patients with venous malformation and Klippel-Trenaunay Syndrome for 6 months, evaluating the change in lesion volume and other factors. The results showed that there was no statistically significant difference in lesion volume over the 6 months and no significant changes in other evaluated factors.

Effects of exercise, metformin, and combination treatments on type 2 diabetic mellitus-induced muscle atrophy in db/db mice: Crosstalk between autophagy and the proteasome

Mengqi Xiang, Xinmeng Yuan, Nianyun Zhang, Liumei Zhang, Yuting Liu, Jingjing Liu, Yaran Gao, Ye Xu, Wen Sun, Qiang Tang, Yuan Zhang, Jiao Lu

Summary: This study investigated the functional role of exercise, metformin, and combination treatment on type 2 diabetic mellitus-induced muscle atrophy. Exercise and metformin interventions can increase insulin sensitivity, but exercise alone is more effective in inhibiting the ubiquitin-proteasome system and alleviating skeletal muscle atrophy. However, the combination treatment exhibits no synergistic effect on muscle atrophy.

Relationship between mid-sleep time and depression, health-related quality of life, and sleep deprivation in the 2018 Korea Community Health Survey

Mee-Ri Lee, Sung Min Jung, Seung Hee Choi, Hyeonji Hwang, Youngs Chang, Young Hwangbo

Summary: This study found that individuals with later mid-sleep time (MST) had a higher risk of depression, poor quality of life, poor sleep quality, and excessive daytime sleepiness. On the other hand, earlier MST was associated with good sleep quality. This association was significant in both men and women.

Fate of melatonin orally administered in preterm newborns: Antioxidant performance and basis for neuroprotection

Francesca Garofoli, Valentina Franco, Salvatore Aversa, Micol Angelini, Raffaella F. Cabini, Sara Cociglio, Stefania Longo, Michela Palmisani, Camilla Pisoni, Francesco M. Risso, Stefano Ghirardello, Simona Orcesi

Summary: This study aimed to evaluate the endogenous production and metabolism of melatonin (ME) in preterm infants, as well as its ability to counteract reactive oxygen species (ROS). The study found that preterm infants are unable to produce detectable levels of endogenous ME, but administration of ME orally resulted in significant levels of ME and its metabolite 6-OH-ME. Furthermore, there was a trend of decreased malondialdehyde (MDA) levels in the ME group after treatment.

The preferential utilization of hepatic glycogen as energy substrates in largemouth bass (Micropterus salmoides) under short-term starvation

Nihe Zhang, Xiaoyuan Wang, Zhihao Han, Ye Gong, Xuxiong Huang, Naisong Chen, Songlin Li

Summary: This study aimed to elucidate the mechanism of energy metabolism in largemouth bass. Short-term starvation led to an up-regulation of crude protein in the liver, while reducing the liver index, visceral index, and hepatic glycogen content. Gene expression analysis showed down-regulation of insulin-like growth factor 1 and TOR pathway genes, and up-regulation of lipolysis-related genes, while inhibiting lipogenesis and gluconeogenesis. Short-term starvation effectively depleted hepatic glycogen accumulation and mobilized it for energy.
