The origin of land plants from algae is a long-standing question in evolutionary biology. It is becoming increasingly clear that many characters that were once assumed to be "embryophyte-specific" can in fact be found in their closest algal relatives, the streptophyte algae. One such case is the phenylpropanoid pathway. While biochemical data indicate that streptophyte algae harbor lignin-like components, the phenylpropanoid core pathway, which serves as the backbone of lignin biosynthesis, has been proposed to have arisen at the base of the land plants...

Background and aim: Takotsubo cardiomyopathy (TC) is an important differential diagnosis of coronary artery disease (CAD), mimicking acute coronary syndrome in clinical symptoms, biomarker profiles and ST-elevation in ECG. Absence of occlusive coronary disease is an essential criterion distinguishing both diseases. The aim of the study was to explore the influence of co-existing incidental CAD on poorer clinical outcomes and all-cause mortality in TC. Design, methods and results: Our mono-centric study cohort constituted 114 consecutive patients diagnosed with TC between 2003 and 2015...

In a previous study, we reported on a quantitative transcriptomic method which confirmed the temporal transcription of developmental fast skeletal muscle myosin heavy chain (fsMyHC) embryonic isoforms in the embryonic Pectoralis major (PM) of the Single Comb White Leghorn (SCWL). The objective of the current study was to further investigate the transcriptional events underlying embryonic PM growth in the SCWL and a genotype exhibiting partial muscular dystrophy, the Low Score Normal (LSN). We hypothesized that within the SCWL and LSN embryos, there would be differences in the temporal transcription of the fsMyHC isoforms and other myogenic regulatory genes...

RATIONALE: Graphene has been found to be a versatile precursor for the generation of mono-endohedral metallofullerenes (EMFs) of alkali and alkali earth metal atoms. Thus, it is important to investigate whether graphene is also a good precursor for the generation of EMFs including multi-metal atoms or some transition metal atoms. METHODS: Experiments were performed on a 7.0 T Fourier transform ion cyclotron resonance (FT ICR) mass spectrometer. Laser ablation mass spectra were obtained by laser irradiation on mixtures of graphene and LaCl3 , YCl3 or HAuCl4 on a stainless steel plate...

OBJECTIVE: Breast cancer (BC) is one of the most common cancers in females. Abnormal proliferation and metastasis are key reasons that cause mortality in BC patients. More and more evidence showed that lncRNA played an important role in the BC development, but the mechanism was not well established. PATIENTS AND METHODS: The expression of lncRNA NEAT1 was detected in 40 BC patients by qRT-PCR technology. MTT and Wound Healing assays were applied to detect the effect of lncRNA NEAT1 in proliferation and metastasis in BC...

Temporomandibular joint (TMJ) ankylosis is a refractory disease that is difficult to predictably treat. This study evaluated the prognosis of using standard alloplastic TMJ prostheses for the treatment of TMJ ankylosis in Chinese patients with severe mandibular deficiency. Patients treated from 2013 to 2015 were reviewed. The computer-aided design and manufacture (CAD/CAM) technique was used to guide bony mass removal and locate the TMJ prosthesis (Biomet, USA). Eleven patients were included in this study. All prostheses were successfully installed and stabilized intraoperatively...

Premenopausal women are known to have less heart disease than their menopausal counterparts and men. However, there is a rising prevalence of coronary artery disease (CAD) in premenopausal females, which necessitates determination of risk factors that negate the effects of hormonal protection. There are few studies describing the prevalence of traditional and emerging risk factors in premenopausal women with CAD. Thus, our objective was to explore the prevalence of traditional and emerging risk factors and features of coronary lesions in premenopausal women with CAD in an Indian population...

Autonomic dysfunction, a relative sedentary lifestyle, a reduced muscle mass and increased adiposity leads to metabolic abnormalities that accelerate the development of coronary artery disease (CAD) in individuals living with spinal cord injury (SCI). An untoward cardiac incident is related to the degree of CAD, suggesting that the occurrence of a significant cardiac event is significantly higher for individuals with SCI Thus, understanding the fundamental hemodynamic mechanisms mediating the response to myocardial ischemia has the potential to positively impact individuals and families living with SCI Accordingly, we systematically investigated if thoracic level 5 spinal cord transection (T5X; paraplegia) alters the arterial blood pressure response to coronary artery occlusion and if the different arterial blood pressure responses to coronary artery occlusion between intact and paraplegic mice are mediated by changes in cardiac output and or systemic peripheral resistance and whether differences in cardiac output are caused by changes in heart rate and or stroke volume...
