Divergent Evolutionary Rates of Primate Brain Regions as Revealed by Genomics and Transcriptomics.

Although the primate brain contains numerous functionally distinct structures that have experienced diverse genetic changes during the course of evolution and development, these changes remain to be explored in detail. Here we utilize two classic metrics from evolutionary biology, the evolutionary rate index (ERI) and the transcriptome age index (TAI), to investigate the evolutionary alterations that have occurred in each area and developmental stage of the primate brain. We observed a higher evolutionary rate for those genes expressed in the non-cortical areas during primate evolution, particularly in human, with the highest rate of evolution being exhibited at brain developmental stages between late infancy and early childhood.

Radiomics and dosiomics for predicting radiation-induced hypothyroidism and guiding intensity-modulated radiotherapy.

To guide individualized intensity-modulated radiotherapy (IMRT), we developed and prospectively validated a multiview radiomics risk model for predicting radiation-induced hypothyroidism in patients with nasopharyngeal carcinoma. And simulated radiotherapy plans with same dose-volume-histogram (DVH) but different dose distributions were redesigned to explore the clinical application of the multiview radiomics risk model. The radiomics and dosiomics were built based on selected radiomics and dosiomics features from planning computed tomography and dose distribution, respectively.

Tanshinol alleviates ischemia-induced myocardial fibrosis via targeting ERK2 and disturbing the intermolecular autophosphorylation of ERK2.

Myocardial fibrosis is the fundamental remodeling process in myocardial ischemia (MI) and also the major contributor of heart failure and death. Tanshinol (Danshensu in Chinese, DSS), a major ingredient of salvia mitiorrhiza Bunge (Lamiaceae) root, exerted significant cardio protection effects. In this study, we aimed to identify the action target and then uncover the mechanism of DSS alleviating myocardial fibrosis.

Particle transfer mediates dermal exposure of consumers to plasticizers in eraser and pen accessories.

Dermal exposure to chemicals released from daily consumer products is a rising concern, particularly for children who are susceptible to unintentional hand-to-mouth transfer and related chemical exposure risk. However, chemical transfer induced by tiny particles of intact products has yet to be adequately addressed. The objective of the present study was to determine the potentiality of particles release from intact erasers and pen grips upon dermal contact by measuring the migration rates of the embedded plasticizers (phthalates and its alternatives).

Integrative Omics Reveals Rapidly Evolving Regulatory Sequences Driving Primate Brain Evolution.

Although the continual expansion of the brain during primate evolution accounts for our enhanced cognitive capabilities, the drivers of brain evolution have scarcely been explored in these ancestral nodes. Here, we performed large-scale comparative genomic, transcriptomic, and epigenomic analyses to investigate the evolutionary alterations acquired by brain genes and provide comprehensive listings of innovatory genetic elements along the evolutionary path from ancestral primates to human. The regulatory sequences associated with brain-expressed genes experienced rapid change, particularly in the ancestor of the Simiiformes.

Concurrent chemotherapy using taxane plus cisplatin cisplatin alone in high-risk nasopharyngeal carcinoma patients with suboptimal response to induction chemotherapy.

Background: Detectable Epstein-Barr virus (EBV) DNA levels and unsatisfactory tumor response to induction chemotherapy (IC) could be used to guide the risk-adapted treatment strategy of locoregionally advanced nasopharyngeal carcinoma (LANPC) before concurrent chemoradiotherapy. We aim to compare the efficacy and safety of concurrent chemotherapy using taxane plus cisplatin [double-agent concurrent chemotherapy (DACC) group] with those of cisplatin alone [single-agent concurrent chemotherapy (SACC) group] in high-risk LANPC.

Methods: Overall, 197 LANPC patients with detectable EBV DNA or stable disease (SD) after IC were retrospectively included.

The cognitive dysfunction of claustrum on Alzheimer's disease: A mini-review.

Alzheimer's disease (AD) is one of the most common neurodegenerative diseases characterized by cognitive deficits and dementia. AD entails predominant pathological characteristics including amyloid beta (Aβ) plaque formation, neurofibrillary entanglements, and brain atrophy, which gradually result in cognitive dysfunctions. Studies showed that these pathological changes are found in a myriad of brain structures, including the claustrum (CLA), a nucleus that penetrates deeply into the brain and is extensively interconnected to various brain structures.

[Regulatory Effect of Vitamin D on Renin Expression at Maternal-Fetal Interface].

Objective: To investigate the regulatory effect and mechanism of vitamin D on the local renin-angiotensin system at maternal-fetal interface in the pathological process of preeclampsia (PE).

Methods: The mRNA and protein expression of renin in decidua of normal pregnancy and PE placentas was determined by RT-PCR and Western blot. Normal decidual tissues were treated with active and inactive vitamin D for 48 h and the expressions of renin and vitamin D deactivating enzyme CYP24A1 were determined by RT-PCR and Western blot.

Reconstruction of complex chest wall defects: A case report.

Background: Chronic radiative chest wall ulcers are common in patients undergoing radiation therapy. If not treated early, then symptoms such as erosion, bleeding and infection will appear on the skin. In severe cases, ulcers invade the ribs and pleura, presenting a mortality risk.

Spatiotemporal evolution characteristics of the late frost damage risk to shrubby tea trees in tea region, southwest China from 1971 to 2020.

Understanding the spatiotemporal evolution characteristics of the risk of late frost damage has scientific guiding significance for optimizing the regional agricultural production layout and varie-ty tuning. Based on the daily meteorological data of 65 weather stations in the southwest China tea region from 1971 to 2020, we analyzed variation characteristics of the last frost date (LFD), tea bud open date (BOD), and their relationships, constructed frost damage probability index and frost damage severity index of spring shoots of shrubby tea trees, and analyzed the spatiotemporal evolution chara-cteristics of the late frost damage risk of shrub tea trees in the southwest tea region. The results showed that both the BOD and LFD had a significant ahead of trend from 1971 to 2020 and the early rate of the LFD was relatively faster than that of the BOD in the southwest tea region.

A Novel Personal Passive Sampler for Collecting Gaseous Phthalates.

Dermal absorption of gaseous chemicals is an important contributor to increased health risk and has yet to be adequately addressed due to the lack of available sampling techniques. In the present study, a novel personal passive sampler consisting of a housing (embracing a polydimethylsiloxane (PDMS) disk as the sorbent phase, a membrane filter, and a stainless-steel mesh) and a watchband (traditional wristband) was constructed and used to characterize gaseous phthalates (PAEs) near the air-skin interface. In a real-life setting, the utility of the passive sampler was validated by comparing the composition profiles of PAEs in the PDMS disks and in active samples and watchbands.

Acupuncture: A therapeutic approach against acne.

Acne is a common but chronic skin disease that influence large population especially juvenile. Acne can continue, begin, or grow into severe form in adult age, affecting face, back, and chest. It may be a serious issue if not cared or treated timely.

Neuroglobin expression and function in the temporal cortex of bilirubin encephalopathy rats.

Bilirubin encephalopathy (BE) is a neurological syndrome in newborns, mainly caused by neuronal injury due to excessive oxidative stress produced by unconjugated bilirubin (UCB). Neuroglobin (NGB) can protect the brain by removing oxidative stress species, but its expression and significance in BE are not clear. To address this question, the neonatal BE model was established by injecting UCB into the cerebellomedullary cistern of 7-day-old SD rats.

An immune-related seven-lncRNA signature for head and neck squamous cell carcinoma.

In this study, we developed a long noncoding RNA (lncRNA)-based prognostic signature for stratification of patients with head a nd neck squamous cell carcinoma (HNSCC). In total, 493 HNSCC samples obtained from the Cancer Genome Atlas database were divided into training and testing cohorts (3:2 ratio). We identified 3913 immune-related lncRNAs in the HNSCC training cohort by Pearson correlation analysis; only seven were independently associated with overall survival and were used to develop an immune-related lncRNA prognostic signature (IRLPS) grouping of HNSCC patients into high- and low-IRLPS subgroups.
