Abstract
Evaluate the effect of the fresh air purification system on the improvement of indoor PM2.5 levels in a primary school classroom in Jinan City, Shandong Province. Our purpose is to explore the optimal operating time of the fresh air system and the main factors that affect the fresh air purification system to improve indoor air quality. From December 9, 2019 to December 10, 2019, two classrooms of the same area on the third floor of a primary school building in Jinan City, Shandong Province were selected as monitoring points. During the operation of the fresh air purification system, the PM2.5 concentration in the classroom is reduced by an average of 48.1%-61.5% compared to the outdoor PM2.5 concentration. After running for about 2 hours, the indoor PM2.5 concentration decreased to a relatively stable concentration level. The operating time of the fresh air purification system, student activities between classes, indoor temperature, indoor relative humidity, and outdoor PM2.5 concentration are important factors that affect the indoor particulate removal rate. In the case of a certain amount of fresh air and indoor area, closing doors and windows and appropriately extending the operation time of the fresh air purification system can improve the air quality in the classroom to a certain extent and protect the health of students.

Background/significance. Cardiac rehabilitation (CR) significantly reduces death, reoccurring cardiac events, hospital admissions while improving quality of life. However, it is still poorly attended with participation rates worldwide between 20-50%, worsened for rural and remote patients by the tyranny of distance, work responsibilities and transportation. Web-based CR can provide an alternative, patient centred, flexible delivery option. Co-design with consumers and clinicians is recommended to tailor web-based CR to their needs and preferences as a means of increasing attendance.
Purpose. The objective of this study is to describe how patient-generated data through workshops on desired content and features informs technology and implementation specifications for the patient portal of a CR website.
Methods. UX Design theoretical framework, using a co-design workshop, with thematic analysis, a survey, and the System Usability Scale was used to report outcomes.
Results. Based on the feedback from participants in rural and remote SA, desired content and features were updated for improving user experience. We recruited 27 participants across 4 regional Local health Networks in SA. The median age of participants was 71.0 (IQR 58-78), 14 (51.9%) were female and 27 (100%) had completed a cardiac rehabilitation program. More than half used a smart phone (16; 59.3%) and Facebook (21; 77.8%). Overall usability remains low based on a mean SUS score of 63.4 (SD 21.1), however there was a tendency to usability improving over time.
Conclusion. The co-design process has contributed to the development of the CR website, improving desired content and features. Improved usability scores can be achieved through further incorporating consumer feedback into the development of the CR website.

Abstract
PURPOSE The safety of mirabegron 50mg monotherapy was comprehensively assessed versus placebo for overactive bladder. METHODS A systematic literature search was conducted up to June, 2020 using PUBMED, EMBASE and Cochrane Library. Randomized controlled trials evaluating safety of mirabegron in overactive bladder were collected, and safety was assessed according to 15 adverse events. Adverse events were widely selected to be assessed if they could be calculated. Heterogeneity among studies was assessed by using the χ2 test based on the Q and I2 tests. Pooled effect sizes were calculated using fixed model if I2<50%, otherwise a random-effects model was chosen. The outcomes were nasopharyngitis, dry mouth, hypertension, constipation, headache, dyspepsia, urinary tract infection, dizziness, blurred vision, nausea, cardiovascular events, influenza, electrocardiogram QT prolonged, upper respiratory tract infection and high blood pressure. RESULTS In all, 10 peer-reviewed trials comprising 6135 patients were identified. Compared with placebo, mirabegron 50mg had an unfavorable safety profile resulting in nasopharyngitis (OR, 1.54[95% credible interval, 1.05-2.25]; P=0.03. No statistical difference was found between mirabegron 50mg and placebo groups in other 14 outcomes. CONCLUSION Mirabegron 50mg is further confirmed to be nearly as safe as placebo, expect for nasopharyngitis. Nasopharyngitis is associated with mirabegron 50mg monotherapy for patients with overactive bladder.

Abstract
Objective: To understand the epidemiological and genotypic characteristics of imported cases of measles virus of D8 genotype in Hebei province. Methods: Epidemiological investigation of measles cases in surveillance was carried out. The throat swabs of the measles cases in acute phase were collected for real time RT-PCR identification, measles virus culture and genotype identification. Results: A total of 36 imported measles cases of genotype D8 were detected. The cases were mainly distributed in 8 counties of Handan city. Number of confirmed measles cases in Cheng'an county was the highest, accounting for 58.33% (21/36) of all the reported cases. All patients had fever and rash, and 55.55% (20/36) of the cases were under 2 years old and 86.11% (31/36) of the cases had no immunization history. The children with pneumonia accounted for 44.12% (15/34) of the total children with D8 genotype measles virus infection. The nucleotide and amino acid homologies between the imported measles virus genotype D8 and the WHO reference strain of D8 genotype (D8-Manchester.UNK/30.94) were 98.4%-98.6% and 97.3%, respectively. Compared with the strains of H1 genotype in China, the nucleotide and amino acid homologies were 92.8%-93.1% and 93.3%, respectively. Conclusions: The imported cases of measles virus of D8 genotype might have caused local transmission in Hebei province. Molecular epidemiological surveillance for measles virus needs to be further strengthened. It is necessary to detect and control the epidemic early and improve the coverage rate and timely rate of measles vaccination. It is also important to prevent cross infection in hospitals.

Abstract
OBJECTIVE Experimental autoimmune myocarditis (EAM) is characterized by pronounced macrophage infiltration, cardiac necrosis, and cardiac fibrosis. Our previous studies have demonstrated that suppressed androgen receptor (AR) enables anti-inflammation to promote tissue repair by decreasing M1 macrophages and increasing M2 macrophages in an EAM model. Given that autophagy mediates inflammatory response in macrophages, we investigated whether AR inhibition executes its protective role in inflammation through the autophagy pathway in EAM. MATERIALS AND METHODS To determine whether AR inhibition can perform its anti-inflammatory effects by upregulating autophagy, we pre-treated mice with 3-methyl adenine (3-MA), a pharmacological inhibitor of autophagy. Immunofluorescence assay and Western blot were used to detect autophagy levels and autophagy activity in five different groups. Immunofluorescence marked F4/80 and LC3 to illustrate the autophagy level in macrophages. TUNEL assays were used to detect the apoptosis level in heart tissue of five different groups. RESULTS We demonstrated that AR inhibition resolves injury with sustained inhibition of inflammatory cytokines associated with enhanced autophagy, especially in macrophages. Increased LC3II/I expression corroborated complete autolysosome formation detected by electron microscopy and correlated with degradation of SQSTM1/p62 in the AR inhibition group by Western blot. These effects could be reversed within 3-MA, a pharmacological inhibitor of autophagy. Specifically, pharmacological inhibition of autophagy increased apoptosis and inflammation, which could be attenuated by AR inhibition. CONCLUSIONS AR inhibition alleviates the inflammatory response and tissue apoptosis by enhancing autophagy, especially in macrophages.

Abstract
Objective: To evaluate the efficacy of high-risk HPV (HR-HPV) genotyping with vaginal self-sampling in primary screening and combining cytology or viral load for HR-HPV positive as secondary screening strategies. Methods: The data referring to HR-HPV genotyping of self-collected sample with mass array matrix-assisted laser desorption-ionization time-of-flight mass spectrometry (MALDI-TOF-MS), HR-HPV viral load of physician-collected sample with hybrid capture Ⅱ (HC-Ⅱ), liquid-based cytology and histology of 8 556 women were from Shenzhen cervical cancer screening trial Ⅱ (SHENCCAST-Ⅱ) conducted between April 2009 and April 2010. The data were reanalyzed to determine the sensitivity and specificity to cervical intraepithelial neoplasia (CIN) of grade 2 or worse (CIN Ⅱ+), CIN of grade 3 or worse (CIN Ⅲ+) when HR-HPV genotyping combining with colposcopy as primary screening strategy based on varied HR-HPV subtype (strategy 1, including 5 sub-strategies: 1a: HPV 16/18 positive; 1b: HPV 16/18/58 positive; 1c: HPV 16/18/58/31/33 positive; 1d: HPV 16/18/58/31/33/52 positive; 1e: any HR-HPV positive). The data were also compared to determine the efficacy of cytology (strategy 2, including 5 sub-strategies: 2a, 2b, 2c, 2d, 2e) or HR-HPV viral load (strategy 3, including 4 sub-strategies: 3a, 3b, 3c, 3d) of physician-collected sample as a triage with HR-HPV genotyping for self-sampling HR-HPV positives. Results: (1) The HR-HPV positive rate was 13.77% (1 178/8 556) in the self-collected samples of 8 556 pregnant women. Of them,the prevalences of HPV 16/18, HPV 16/18/58, HPV 16/18/58/31/33 and HPV 16/18/58/31/33/52 were 3.16% (270/8 556), 5.14% (440/8 556), 6.66% (570/8 556) and 9.81% (839/8 556), respectively. The HR-HPV viral load ≥10 relative light units/control (RLU/CO) was 8.87%(759/ 8 556), while cytological results ≥atypical squamous cell of undetermined signification (ASCUS) were 12.05% (1 031/8 556). (2) The strategy 1e had the highest sensitivities for CIN Ⅱ+, CIN Ⅲ+ which were 92.70% and 94.33%,respectively,among 14 sub-strategies,while the lowest specificity and positive predictive value (PPV). Meanwhile,the required colposcopy referral rates were much higher than other 13 sub-strategies (13.77%). The other 4 sub-strategies of strategy 1 (1a, 1b, 1c, 1d), strategy 1a had the highest specificities for CIN Ⅱ+ and CIN Ⅲ+ (97.92%, 97.69%, respectively), while 1d had the highest sensitivities for CIN Ⅱ+ and CIN Ⅲ+ (88.41%, 92.20%, respectively). (3) Both strategies of referring self-sampling HPV 16/18 positives for immediate colposcopy followed by triage physician-collected sample cytology (≥ASCUS) or viral load (≥10 RLU/CO) for non-HPV 16/18 positives had significantly higher sensitivity and specificity for CIN Ⅱ, CIN Ⅲ+, as well as lower referral rates (strategy 2a and 3a). Additionally, based on these two secondary screening strategies, cumulatively using the other four HR-HPV (HPV 58, 31, 33 and 52) positives as triage for immediate colposcopy showed an enhanced sensitivity. Conclusions: Primary HR-HPV cervical cancer screening strategy based on self-sampling with triage of cytology (≥ASCUS) or viral load (≥10 RUL/CO) provides a good balance among sensitivity, specificity for CIN Ⅱ+ and CIN Ⅲ+ and the number of tests required, referral rates. The efficacy of HR-HPV genotyping combining cytology or viral load secondary screening strategies will have a spiral escalation when HPV 58, 31, 33, 52 are included.

Abstract
Objective: To systematically analyze the impact of PM2.5 exposure on children's behavior. Methods: Use air pollution, fine particulate matter, children, students, child behavior, neurobehavior, attention, autism, autism spectrum disorder, attention deficit hyperactivity disorder, hyperactivity, and bad behavior as Chinese keywords. Use air pollution, fine particulate matter, particulate matter, PM2.5, children, student, behavior, autism, attention, intention, neurobehavior, attention deficit hyperactivity disorder, ADHD, ASD as English keywords. Journal papers and grey literature were searched from CNKI, Wanfang Data Knowledge Service Platform, PubMed and Web of Science database from their inception to Nov 2019, which are related to PM2.5 and children behavior problems. The search period is as of November 2019, and the languages are limited to Chinese and English. The inclusion criteria included the exposure factor of the study as PM2.5; the results of the study included behavioral disorders and related diseases; the languages of the included literature were Chinese and English; original research papers; case-control, cohort or cross-sectional studies. Exclusion criteria include animal experiments; repeated reports; review articles; research exposure factors do not include PM2.5; children self-harm and illegal behaviors. Finally, 25 articles were included. Results: Among the 25 included articles, 12 studies discussed the relationship between PM2.5 exposure and childhood behavioral disorders, 13 discussed the relationship between PM2.5 exposure and abnormal behaviors in children, and 5 studies based on the Chinese population. According to the research design, it is divided into birth cohort studies (15), cross-sectional studies (5), and case-control studies (5). China mainly uses cross-sectional studies and case-control studies. The results of the study suggest that PM2.5 exposure will increase the risk of children's behavioral problems, with both short-term and long-term effects. Short-term exposure to PM2.5 can easily cause mild abnormal behaviors in children, and long-term exposure may increase the risk of children's behavioral disorders. The fetal period and the infant period may be the key exposure window for the occurrence of children's behavior problems. Conclusion: There may be a certain correlation between PM2.5 exposure and children's behavioral problems. In future studies, longitudinal cohort studies should be carried out to enhance the causal relationship between fine particulate matter pollution and children's behavioral problems.

Abstract
OBJECTIVE To explore the correlation of the growth differentiation factor-15 (GDF-15) with the severity of chronic heart failure (CHF) in patients with coronary atherosclerosis. PATIENTS AND METHODS 300 coronary atherosclerosis patients with CHF treated in our hospital from January 2019 to December 2019 and 300 healthy people (control group) were collected and retrospectively analyzed. The basic clinical information of the patients, such as age, gender, smoking/drinking history, waist-hip ratio, BMI and blood lipid were collected, and GDF-15, cystatin C and c-reactive protein (CRP) were determined. The severity of heart failure was classified. RESULTS No significant differences in clinical information were found such as age, gender, smoking/drinking history, waist-to-hip ratio, BMI and blood lipid. However, there were significant differences in GDF-15, cystatin C and CRP among patients with different severities of heart failure. The GDF-15 level was 582.6 ± 104.4 pg/ml in patients with grade IV heart failure and 408.4 ± 94.8 pg/ml in patients with grade I heart failure. There was a significance after GDF-15, cystatin C and CRP were adjusted (p = 0.03) and also after the clinical information and GDF-15 were adjusted (p < 0.001). CONCLUSIONS GDF-15 level is correlated with the CHF severity in patients with coronary atherosclerosis, indicating that it is a potential index to evaluate the CHF severity, providing clues to the biological mechanism and treatment of heart failure.

Abstract
Objective: Evaluation of the clinical value of the BioPerfectus multiplex real time (BMRT)-HPV for cervical cancer screening. Methods: Physician-collected specimens of 1 495 women who were positive of Cobas 4800 HPV (Cobas-HPV), HPV genotyping based on SEQ uencing (SEQ-HPV), and (or) cytology ≥low grade squamous intraepithelial lesion (LSIL) in the primary screening of Chinese Multiple-center Screening Trial (CHIMUST), and 2 990 women selected from those who were negative of primary screening in the same project through nested control randomization with age-matching were tested for BMRT-HPV, which reported type-specific viral loads/10 000 cells in each specimen. With comparing to Cobas-HPV results and taking cervical histopathological diagnosis as the endpoint, the concordance of high-risk (HR)-HPV subtypes among the three assays was explored ,and the sensitivity and specificity of BMRT-HPV for cervical cancer screening were evaluated. Results: (1) The overall agreenment of HR-HPV subtypes between BMRT-HPV and Cobas-HPV, or SEQ-HPV test sample was 94.8%, 94.4%, with Kappa values 0.827, 0.814. (2) The sensitivity and specificity for cervical intraepithelial neoplasia (CIN) Ⅱ+ of BMRT-HPV, Cobas-HPV and SEQ-HPV were 92.62%, 94.26%, 93.44% and 84.67%, 83.25%, 82.76%, respectively. There were no significant difference in sensitivity among the three HPV assays (all P>0.05), but the specificity of BMRT-HPV for CIN Ⅱ+ was higher than those of Cobas-HPV and SEQ-HPV (P<0.01). The sensitivity for CIN Ⅲ+ of three HPV assays were all 100.00%, and the specificity for CIN Ⅲ+ of BMRT-HPV was higher than those of Cobas-HPV and SEQ-HPV (83.40% vs 81.95%, 83.40% vs 81.50%; P<0.01). The number of pathological examinations of colposcopy for cervical biopsy detected in 1 case of CIN Ⅱ+ or CIN Ⅲ+ in BMRT-HPV was less than those in Cobas-HPV and SEQ-HPV (P<0.01). When using HPV 16/18 + cytology ≥atypical squamous cell of undetermined signification (ASCUS) to triage HPV positive women among three assays, there was no different in the sensitivities of detecting CIN Ⅱ+ and CIN Ⅲ+ (P>0.05). The specificity BMRT-HPV was slightly higher than those in Cobas-HPV or SEQ-HPV (all P<0.05), and the colposcopy referral rate was lower than those in Cobas-HPV and SEQ-HPV (all P<0.05). Conclusions: BMRT-HPV is as sensitive as Cobas-HPV or SEQ-HPV for primary cervical cancer screening, and has higher specificity. Therefore it could be used as a primary screening method for cervical cancer, which is worthy of clinical application.

Abstract
Abstract
Background
The prevalence of left ventricular hypertrophy (LVH) is strongly related with established cardiovascular disease (CVD) risk factors and, hence, there has been some uncertainty about its independent relevance for ischaemic heart disease (IHD) after taking account of such risk factors.
Purpose
To examine the associations of LVH with prevalent and incident cases of IHD after adjustment for established risk factors for CVD in a population-based study of Chinese adults.
Methods
The prospective China Kadoorie Biobank cohort study was conducted in the general population of 5 urban and 5 rural areas in China, with a baseline survey in 2004–2008. A random sample of 24,786 participants had a 12-lead electrocardiogram (ECG) recorded at the second resurvey in 2013–2014. Electronic records of ECG tracings were used to estimate LVH using 5 different criteria (Sokolov, Cornell, Romhilt-Estes, Gubner and Mortara). IHD cases were recorded by linkage to electronic records of hospitalisation, death and disease registries. Cox regression was used to estimate the associations of LVH with prevalent (n=1325) and incident (n=900) cases of IHD after adjustment for age, sex, region, prior vascular disease, smoking, alcohol, SBP, diabetes, lipids and body mass index (BMI).
Results
The overall prevalence of LVH in the population varied depending on the criteria used for detection (Mortara [10%], Sokolov [14%], Cornell [6%], Romhilt-Estes [4%] and Gubner [1%]). The prevalence of LVH (using Sokolov) increased with age and was higher in men than women (20% vs 10%) and linearly with levels of SBP, but also by ∼10-fold between the 10 regions in China. Irrespective of which criteria were used for detection (Table), LVH was strongly associated with both prevalent and incident cases of IHD after adjustment for age, sex, region and established CVD risk factors. Any one measure of LVH was associated with an adjusted OR (95% CI) of 1.30 (1.10, 1.53) for prevalent IHD and 1.40 (1.20, 1.64) for incident IHD, respectively.
Conclusions
Overall, 1 in 10 Chinese adults had LVH, and LVH was associated with 30% higher risk of prevalent IHD and 40% higher risk of IHD independent of established CVD risk factors.

Abstract
This article was published ahead of print on the official website of Chinese Journal of Ophthalmology on March 14, 2020. Novel coronavirus pneumonia broke out and spread to the whole nation since December 2019. The fight against the virus is now at a critical stage. Previous epidemiological investigations and animal experiments suggested aerosol could perform as a virus transmitter. Based on the clinical observation, the possibility of aerosol transmission of 2019 novel coronavirus has aroused much attention. This article focuses on the feature of aerosol transmission and the pathogens involved in. We analyze the possibility of aerosol transmission of the novel coronavirus. Relevant strategies for preventing novel coronavirus pneumonia are established for the medical personnel and general public during their work or daily life. (Chin J Ophthalmol, 2020, 56:653-656).

Abstract
Objective: To investigate the use of p16(INK4a) immuno-stained cytology as the primary screening for cervical cancer prevention. Methods: From March to August 2018, 902 women from Shenzhen and surrounding area were recruited for cervical cancer screening with ThinPrep Cytologic Test (TCT), cobas4800 HPV test, and p16(INK4a) co-test. Colpo/biopsies were performed using the point of interest biopsy protocol of directed and random cervical biopsies plus endocervical curettage for all women, any of whose tests was positive. Two senior cytopathologists interpreted TCT and p16(INK4a) test. The performance of p16(INK4a) for early detection of CIN2+ and inter-observer reproducibility of the interpretation of p16(INK4a) were evaluated. Results: The positive rates of HPV test, p16(INK4a) co-test and TCT diagnosed as LSIL/AGC or higher grade were 8.1% (73/902), 6.8% (61/902) and 4.7% (42/902), respectively. Colposcopy referring rate was 79.6% (109/137), among which 10 cases were diagnosed as CIN2+ (5 cases of CIN2 and 5 cases of CIN3). The sensitivity and specificity for CIN2+ of p16(INK4a) test, TCT (LSIL/AGC or higher grade) and HPV test were 90.0%, 80.0%, 100.0% and 90.9%, 91.9%, 82.5%, respectively. Compared to TCT and HPV test, there was no significant difference in sensitivity and specificity between p16(INK4a) and TCT/HPV test (P>0.05). The Kappa value of the 2 cytopathologists in interpreting p16(INK4a) and TCT was 0.944 and 0.425, respectively (P<0.05). Conclusions: p16(INK4a) for cervical cancer screening is equally sensitive to HPV test and specific to TCT while subjective difference of cytopathologists' interpretation of p16(INK4a) is small. Therefore, p16(INK4a) can be used as a new cervical cancer screen method for its better diagnostic performance.

Abstract
Apocynum venetum L. is a traditional Chinese medicinal herb with great potential to treat angiocardiopathy. Its major medicinal constituents are flavonoids. However, the natural habitats of A. venetum are typically affected by salt stress, which can modify both biomass and accumulation of medicinal compounds. In this study, the effects of salt stress on growth and development of A. venetum, accumulation of flavonoids and expression patterns of genes involved in flavonoid biosynthesis were evaluated. In general, the growth and development of seedlings (seedling height, root length, leaf length, leaf width and seed germination) were inhibited by salt stress. Unlike typical halophytes, there was no optimal NaCl concentration range that promoted growth and development, but seedlings had an elevated DW/FW ratio under salt stress (induced by irrigation with 50, 100, 200 or 400 mm NaCl). Furthermore, quercetin and kaempferol were significantly accumulated in A. venetum seedlings under salt stress, resulting in a balanced content and reduced FW. Moreover, the expression of AvCHS, AvCHI and AvF3GT was inhibited by salt stress; however, AvF3'H, AvF3H and AvFLS, which are involved in the flavonol synthesis pathway, were up-regulated under salt stress, consistent with a decrease in total flavonoids and an increase of flavonols (quercetin and kaempferol). In summary, cultivation of A. venetum in saline soils appeared to be feasible and improved the medicinal quality of A. venetum (quercetin and kaempferol accumulation under salt stress), thus this species can effectively utilize saline soil resources.

Abstract
Silicon accumulation type modulators offer prospects of high power efficiency, large bandwidth and high voltage phase linearity making them promising candidates for a number of advanced electro-optic applications. A significant challenge in the realisation of such a modulator is the fabrication of the passive waveguide structure which requires a thin dielectric layer to be positioned within the waveguide, i.e. slotted waveguides. Simultaneously, the fabricated slotted waveguide should be integrated with conventional rib waveguides with negligible optical transition losses. Here, successful integration of polysilicon and silicon slot waveguides enabling a low propagation loss 0.4-1.2 dB/mm together with an ultra-small optical mode conversion loss 0.04 dB between rib and slot waveguides is demonstrated. These fabricated slot waveguide with dielectric thermal SiO2 layer thicknesses around 6 nm, 8 nm and 10 nm have been characterized under transmission electron microscopy allowing for strong carrier accumulation effects for MOS-capacitor electro-optic modulators.

Abstract
1. The Tibetan chicken, which is an indigenous breed living on the Tibetan Plateau, exhibits hypoxic adaptations to its high-altitude environment. However, the molecular mechanism behind this hypoxic adaptation is still unclear. This study aimed to investigate differentially expressed miRNAs involved in hypoxic adaptation through high-throughput RNA sequencing. 2. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to verify the differentially expressed miRNAs and their target genes in chicken embryonic heart tissues and fibroblasts. Luciferase reporter assays were performed to confirm the relationship between miRNAs and target genes. 3. The study identified 37 differentially expressed miRNAs in Tibetan chicken embryonic heart tissues, including 20 up- and 17 down-regulated miRNAs, compared to those found in lowland chickens. Differentially expressed miRNAs were mainly involved in biological processes, such as cell cycle arrest, toll-like receptor signalling pathways, and I-kappa B kinase/NF-kappa B signalling. The data showed that gga-miR-34 c-5p was significantly upregulated in Tibetan chicken tissues and hypoxic fibroblasts, while EHHADH, a target gene of gga-miR-34 c-5p, was downregulated. Moreover, gga-miR-34 c-5p dramatically decreased the luciferase activity of the wild EHHADH, whereas no effect on the mutational EHHADH was found. 4. This study identified miRNA expression profiles in the Tibetan chicken and suggested that miR-34 c-5p acts as a novel miRNA associated with hypoxic adaptation. This facilitates the understanding of molecular mechanisms that underlie long-term exposure to hypoxia.
