BACKGROUND: Endovascular treatment of intracranial aneurysms is associated with higher rates of recurrence and retreatment, though contemporary rates and risk factors for basilar tip aneurysms (BTAs) are less well-described. OBJECTIVE: To characterize progression, retreatement, and retreated progression of BTAs treated with microsurgical or endovascular interventions. METHODS: We retrospectively reviewed records for 141 consecutive BTA patients...

Abnormal inflammatory bias in the maternal-fetal interface leads to reproductive failure in mammals. Placental exosomes are involved in maternal-fetal communication during pregnancy. However, whether the placenta or fetus is involved in regulating the balance of uterine local inflammation through exosomes remains unclear, and the mechanism must be further explored. Here we demonstrated that placenta-specific exosomes are abundant in the peripheral blood of dairy cows during early pregnancy and selectively load miRNAs, such as bta-miR-499...

MicroRNAs are implicated in many cellular processes such as cell differentiation and development, tumorigenesis, and immune regulation. In this study, miR192 was detected using quantitative real-time polymerase chain reaction (qRT-PCR) when MDBK cells were exposed to Escherichia coli. Cells with malfunction of bta-miR-192 were established using transcription activator-like effector nuclease (TALEN) technology. Finally, bta-miR-192 mutant cells were screened for differentially expressed genes using RNA-sequencing (RNA-seq)...

Background: Bone metastases (BMs) are common in patients with breast cancer and can lead to skeletal-related events (SREs), which are associated with increased pain and reduced quality of life (QoL). Bone-targeted agents (BTAs), like zoledronic acid and denosumab, reduce the incidence of SREs and delay progression of bone pain. Materials and methods: We evaluated the management of BMs and pain in six European countries (Belgium, France, Germany, Italy, Spain, and UK) using the Adelphi Breast Cancer Disease Specific Programme, which included a physician survey and patient-reported outcomes (PROs) to assess the impact of BMs on pain and QoL...

Pronounced resistance of lung cancer cells to radiotherapy and chemotherapy is a major barrier to successful treatment. Herein, both tumor hypoxia and the upregulation of the cellular antioxidant defense systems observed during malignant progression can contribute to radioresistance. We recently found that exposure to chronic cycling severe hypoxia/reoxygenation stress results in glutamine-dependent upregulation of cellular glutathione (GSH) levels and associated radiation resistance opening novel routes for tumor cell-specific radiosensitization...

BACKGROUND: The British Thyroid Association (BTA) updated guidelines for the management of differentiated thyroid cancer (DTC) in 2014. A key update was that patients with unifocal disease >10-≤40 mm in diameter, aged <45 years and with no other risk factors could be considered for lobectomy alone. The aim of this study was to retrospectively evaluate the potential impact of these changes on the management of DTC in South East Scotland, and to analyse the characteristics of lobes now potentially considered for observation rather than resection...

Bovine mastitis is an inflammation response of the mammary gland tissues caused mainly by pathogenic bacteria in cows. Previous studies showed that bta-miR-15a and bta-miR-16a modulate immunity and inflammation responses. In this study, we investigated the expression pattern and tissue localization of bta-miR-15a and bta-miR-16a. The expression levels of bta-miR-15a and bta-miR-16a were significantly upregulated in mammary tissues and blood neutrophils of mastitis-infected cows, compared with those of healthy cows (P < 0...

A two-dimensional (2D) surface covalent organic framework (COF), prepared via a surface confined synthesis using 4,4'-azodianiline (DA) and benzene-1,3,5-tricarbaldehyde (BTA) as the precursors, was used as a host network to effectively immobilize arylenevinylene macrocycles (AVMs), and thus can separate AVMs from their linear polymer analogs, which are the common side-products in cyclooligomerization process. Scanning tunneling microscopic (STM) investigations revealed efficient removal of linear polymers by a simple surface binding followed by solvent washing process...

When samples with low amounts of DNA are amplified using short tandem repeats (STRs), stochastic effects such as allele and locus dropout or drop-in, allele imbalance, and increased stutter often occur making data interpretation more difficult. The most common approach to improving STR results from low template samples is to increase the number of PCR cycles. Although more alleles may be recovered, stochastic effects may be exaggerated resulting in more complicated STR profiles. This work reports the effect of additional PCR cycles (29 vs...

The increasing incidence of bladder cancer (BC) and its high rate of recurrence over a 5-year period necessitate the need for diagnosis and surveillance amelioration. Cystoscopy and urinary cytology are the current tools, and molecular techniques such as BTA stat, NMP22, survivin mRNA, and urovysion FISH have attracted attention, however, they suf-fer from insufficient sensitivity or specificity. We developed a novel microfluidic approach for harvesting intact urinary-exfoliated tumor cells (UETCs), either individually or in clus-ters, in a clean and segregated environment, which is crucial to minimize cross-contamination and misreads...

microRNAs (miRNAs) are a class of small non-coding RNAs that play key roles in post transcriptional gene regulation that influence various fundamental cellular processes, including the cellular responses during environmental stresses. However, perusal of literatures revealed few reports on the differential expression of miRNA during thermal stress in Indian native (Bos indicus) cattle breeds. The present investigation aimed to identify differentially expressed miRNAs during thermal stress in Sahiwal (Bos indicus) dairy cattle breed of India, adapted with tropical climate over a long period of time...

This study aimed to explore the roles of microRNAs (miRNAs) in calf rumen development during early life. Rumen tissues were collected from 16 calves (8 at pre-weaning and 8 at post-weaning) for miRNA-sequencing, differential expression (DE), miRNA weighted gene co-expression network (WGCNA) and miRNA-mRNA co-expression analyses. 295 miRNAs were identified. Bta-miR-143, miR-26a, miR-145 and miR-27b were the most abundantly expressed. 122 miRNAs were significantly DE between the pre- and post-weaning periods and the most up- and down-regulated miRNAs were bta-miR-29b and bta-miR-493, respectively...

Devolopment of organic solar cells with high open-circuit voltage ( V OC ) and power conversion efficiency (PCE) simutaniously plays a significant role, but there is no guideline how to choose the suitable photovoltaic material combinations. In our previous work, we developed "the Same-Acceptor-Strategy" (SAS), by utilizing the same electron-accepting segment to construct both polymeric donor and small molecular acceptor. In this study, we further expend SAS to use both the same electron-accepting and electron-donating units to design the material combination...

A major challenge in supramolecular polymerization is controlling the stability of the polymers formed, that is, controlling the rate of monomer exchange in the equilibrium between monomer and polymer. The exchange dynamics of supramolecular polymers based on benzene-1,3,5-tricarboxamide (BTA) can be regulated by copolymerizing molecules with dendronized (dBTA) and linear (nBTA) ethylene glycol-based water-soluble side chains. Whereas nBTAs form long nanofibers in water, dBTAs do not polymerize, forming instead small spherical aggregates...

Botulinum toxin A (BTA) injections into lacrimal gland are being used for refractory epiphora due to intractable lacrimal disorders with success rates reported from 18% to 86%. Most common side effects are transient ptosis and diplopia. We report a case of a 59-year-old female injected with 2.5 units of BTA injection in each lacrimal gland for functional epiphora. The patient had a history of herpes simplex viral keratitis that was quiescent for more than 2 years. After 3 weeks, she developed reactivation of viral keratitis bilaterally, which was successfully managed with antivirals and topical steroids...

A lumbar sympathetic ganglion block (LSB) is a therapeutic method for complex regional pain syndrome (CRPS) affecting the lower limbs. Recently, LSB with botulinum toxin type A and B was introduced as a novel method to achieve longer duration of analgesia. In this study, we compared the botulinum toxin type A (BTA) with botulinum toxin type B (BTB) in performing LSB on patients with CRPS. LSB was performed with either BTA or BTB on patients with CRPS in their lower extremities. The length of time taken for patients to return to the pre-LSB pain score and the adverse effect of LSB with BTA/BTB were investigated...

Beef cow stayability is a complex, economically important trait often used as an indicator of a cow's potential lifetime productivity. Stayability is defined as capability of a cow to maintain a perfect record up to 6 yr of age. This age is commonly cited as a financial break-even point, where initial costs of cow development and maintenance are recovered by her cumulative net income from yearly calf receipts. Later-maturing Bos indicus-Bos taurus crossbred cows may experience reproductive difficulty early in life but have a high potential for a long reproductive life span...
