Pelvic arteriovenous malformation mimicking benign prostatic hyperplasia: A case report.

Pelvic arteriovenous malformation is a rare vascular abnormality, espescially in male patients, and is difficult to treat because of its nature supplied by multiple arterial feeders. We report a 70-year-old male patient admitted due to symptoms of benign prostatic hyperplasia. Ultrasound was performed initially, and no other abnormalities were found other than an enlarged prostate.

Risk factors for the development of premature ventricular complex-induced cardiomyopathy: a systematic review and meta-analysis.

Background: Premature ventricular complexes (PVCs) are a potentially reversible cause of heart failure. However, the characteristics of patients most likely to develop impaired left ventricular function are unclear. Hence, the objective of this study is to systematically assess risk factors for the development of PVC-induced cardiomyopathy.

All-inside arthroscopic anterior cruciate ligament reconstruction with internal brace Ligament Augmentation using semitendinosus tendon autograft: A case series.

Introduction And Importance: Anterior Cruciate Ligament (ACL) reconstruction surgery has been proven to be closely related to the graft healing process, which can last up to 12 months after surgery. In recent years, through various biomechanical and clinical studies, Internal Brace Ligament Augmentation (IBLA) has been shown to protect the graft during these early postoperative stages and improve the outcome of ACL reconstruction. We present this case series of all-inside arthroscopic anterior cruciate ligament reconstruction with IBLA using semitendinosus tendon autografts, with the goal of evaluating postoperative clinical and patient-reported outcomes.

Fine root production in a chronosequence of mature reforested mangroves.

Mangroves are among the world's most carbon-dense ecosystems, but have suffered extensive deforestation, prompting reforestation projects. The effects of mangrove reforestation on belowground carbon dynamics are poorly understood. In particular, we do not know how fine root production develops following mangrove reforestation, despite fine root production being a major carbon sink and an important control of mangrove soil accretion.

Timeliness of contact tracing among flight passengers during the COVID-19 epidemic in Vietnam.

Background: International air travel plays an important role in the global spread of SARS-CoV-2, and tracing of close contacts is an integral part of the public health response to COVID-19. We aimed to assess the timeliness of contact tracing among airline passengers arriving in Vietnam on flights containing COVID-19 cases and investigated factors associated with timeliness of contact tracing.

Methods: We included data from 2228 passengers on 22 incoming flights between 2 and 19 March 2020.

Sensitivity of mangrove soil organic matter decay to warming and sea level change.

Mangroves are among the world's most carbon-dense ecosystems, but they are threatened by rapid climate change and rising sea levels. The accumulation and decomposition of soil organic matter (SOM) are closely tied to mangroves' carbon sink functions and resistance to rising sea levels. However, few studies have investigated the response of mangrove SOM dynamics to likely future environmental conditions.

In Situ Stimulated Raman Scattering (SRS) Microscopy Study of the Dissolution of Sustained-Release Implant Formulation.

Localized drug delivery systems (DDSs) provide therapeutic levels of drug agent while mitigating side effects of systemic delivery. These systems offer controlled release over extended periods of time making them attractive therapies. Monitoring drug dissolution is vital for developing safe and effective means of drug delivery.

Anodal tDCS of the lower limb M1 does not acutely affect clinical blood pressure and heart rate in healthy and post stroke individuals.

Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique increasingly investigated an adjunct modality to enhance the effects of motor therapy. Although the safety of tDCS in relation to cognition, sensation and perception has been well reviewed, there still exists limited information regarding its effects on blood pressure and heart rate. As tDCS is being largely used in conjunction with stroke rehabilitation, it is important that we understand the effects of tDCS on autonomic function in the stroke population.

Structure of fucoidan from brown seaweed Turbinaria ornata as studied by electrospray ionization mass spectrometry (ESIMS) and small angle X-ray scattering (SAXS) techniques.

The purpose of this study is to elucidate both the chemical and conformational structure of an unfractionated fucoidan extracted from brown seaweed Turbinaria ornata collected at Nha-trang bay, Vietnam. Electrospray ionization mass spectrometry (ESI-MS) was used for determining the chemical structure and small angle X-ray scattering (SAXS) provided conformational of the structure at the molecular level. The results showed that the fucoidan has a sulfate content of 25.

Polarity independent effects of cerebellar tDCS on short term ankle visuomotor learning.

Background: Transcranial direct current stimulation (tDCS), an emerging technique of noninvasive brain stimulation, has shown to produce beneficial neural effects in consequence with improvements in motor behavior. There are not many studies examining the use of tDCS for lower limb motor control and learning. Most studies using tDCS for facilitating lower limb motor coordination have applied tDCS to the lower limb motor cortex (M1).

Evidence for a trianion intermediate in the metalation of 4-hydroxy-6,7-dimethoxy-8-methyl-2-naphthoic acid. Methodology and application to racemic 5,5'-didesisopropyl-5,5'-dialkylapogossypol derivatives.

The metalation of 4-hydroxy-6,7-dimethoxy-8-methyl-2-naphthoic acid (8) affording trianion 6 is presented and applied to the regioselective efficient construction of a series of 5,5'-didesisopropyl-5,5'-dialkylapogossypol derivatives 3 that are potent pan-active inhibitors of antiapoptotic Bcl-2 family proteins.
