Cercospora leaf spot (CLS), caused by the fungus Cercospora beticola, is an important determinant of table beet foliar health. Primary inoculum sources include infested crop residues and alternative hosts, but seed-to-seedling transmission has also been reported. We evaluated the localization of C. beticola in table beet seeds and contribution of infested seeds to CLS outbreaks in field studies. In seed dissection experiments, C. beticola was more frequently isolated from the pericarp (95.6%)...

CONCLUSIONS: FDS treatment for recurrent/residual aneurysms after SAC represents a viable treatment option for these challenging cases with acceptable safety and reasonable occlusion rates, although lower than de novo FDS occlusion rates.

CONCLUSIONS: Onyx, a liquid embolic agent, reduces EBL which may explain the shorter surgery duration, higher GTR rates, and lower retreatment rates. Procedural risks and patient selection require further investigation.

CONCLUSIONS: This international survey of spine surgeons demonstrated that currently, there is limited use of IOUS in the surgical management of acute SCI. Understanding the needs of spine surgeons and tailoring educational opportunities may increase the role of IOUS. Given the importance of surgical decompression in enhancing outcomes after acute SCI coupled with the ability of IOUS to assess decompression, greater adoption of IOUS could further enhance the efficacy of decompressive surgery.

Monitoring the quality of water resources is essential to determine environmental impacts and seek sustainable management solutions. In this work, we demonstrated the toxicity of effluents and surface water of an important river in Central Brazil, the Meia Ponte River, using not just physicochemical parameters but also ecotoxicological bioindicators, such as Aliivibrio fischeri, Allium cepa, Lactuca sativa, and Salmonella typhimurium. To complement this data, we analyzed soil toxicity and...

CONCLUSIONS: Results from the first eleven distributions indicate that the EQA scheme has facilitated improved performance of laboratories over time, highlighting the value of implementing such programmes. EQA schemes are critical to safeguarding the reliability of data and diagnoses, especially in situations where NAAT methodologies and protocols are used. In future, funders should make participation in an EQA scheme a requirement for laboratories, and countries can take initiatives to embed...

CONCLUSIONS: Vascular operations, on average, generate 108.47 kg of CO2e from waste and fluoroscopy, the equivalent of driving an average gasoline-powered vehicle for 278 miles. This study found a correlation between increased fluoroscopy time and CO2e. It also found that the rate of emissions differs between different operations, suggesting a role in optimizing fluoroscopy and intraoperative techniques to lower emissions. Efforts to track current energy output from imaging devices, investing in...

In the retina, Ca^(2+) influx through Ca(v)1.4 Ca^(2+) channels triggers neurotransmitter release from rod and cone photoreceptors. Changes in extracellular pH modify channel opening, enabling a feedback regulation of photoreceptor output that contributes to the encoding of color and contrast. However, the mechanisms underlying pH-dependent modulation of Ca(v)1.4 are poorly understood. Here, we investigated the role of the C-terminal domain (CTD) of Ca(v)1.4 in pH-dependent modulation of Ba^(2+)...

OBJECTIVE: To educate health care professionals and nurses on buprenorphine initiations in pregnancy, establish a mutual care agreement to promote therapeutic partnership, and standardize buprenorphine initiation using the Epic electronic health record (EHR) order set.

Reflection exercises have been used within anatomy education to evaluate empathy, humanism, and professionalism. A typical reflection exercise consists of directed prompts to guide the student's reflection as it relates to the experience and/or research question. The aim of this study was to utilize reflections through an open-ended format to enable students to explore their experience participating in donor dissection as they form their professional identity. The "Seven Questions" exercise was...

BRAF-mutated colorectal cancer correlates with poor prognosis and limited response to standard treatments. Combining immune checkpoint inhibitors with BRAF/MEK inhibitors shows promise against BRAF-mutant melanoma in both preclinical and clinical trials. Therefore, we hypothesized that the treatment would be effective against BRAF-mutant colorectal cancer. In this study, we assessed the efficacy of combining immune checkpoint inhibitors with BRAF and/or MEK inhibitors in BRAF-mutant colorectal...

Dravet syndrome (DS) is a severe developmental epileptic encephalopathy marked by treatment-resistant seizures, developmental delay, intellectual disability, motor deficits, and a 10 to 20% rate of premature death. Most patients with DS harbor loss-of-function mutations in one copy of SCN1A, which encodes the voltage-gated sodium channel (Na(V))1.1 alpha subunit and has been associated with inhibitory neuron dysfunction. Here, we generated a split-intein form of SCN1A and used a dual-vector...

CONCLUSIONS: TEEM esophagectomy is a safe approach with acceptable postoperative morbidity and mortality and shorter operative times compared with historical norms.

United States Special Operations Forces (SOF) experience neurobehavioral symptoms that can adversely affect training and combat operations. Understanding the neurobiological basis for these symptoms may guide prevention and treatment. In 29 male active-duty SOF with mean (SD) 17(4) years of service, we tested whether self-reported symptoms of apathy, disinhibition, and executive dysfunction measured by the Frontal Systems Behavior Scale, were related to functional magnetic resonance imaging and...

CONCLUSIONS: Intracranially infused EGFR806-CAR T cells were tolerable at tested doses, with a best response of stable disease. EGFR is a potentially useful target for cellular therapy against pediatric brain tumors, particularly high-grade gliomas.

Breathing regulation depends on a highly intricate and precise network within the brainstem, requiring the identification of all neuronal elements in the brainstem respiratory circuits and a comprehensive understanding of their organization into distinct functional compartments. These compartments play a pivotal role by providing essential input to three main targets: cranial motoneurons that regulate airway control, spinal motoneurons that activate the inspiratory and expiratory muscles, and...

Superior vena cava (SVC) syndrome is a clinical condition characterized by impaired venous return from the upper body due to intrinsic or extrinsic obstruction of the SVC. Endovascular stenting has become an effective intervention for symptomatic relief. However, the procedure carries a rare risk of life-threatening complications, including SVC perforation and cardiac tamponade. This study describes a 60-year-old male with SVC syndrome secondary to squamous cell carcinoma of the lung who...

CONCLUSIONS: Overall, patients spend an average of 16 s per item and 2 min per PRO instrument in clinical trial studies. PROs are a crucial component of clinical trial outcomes data and can be efficiently completed electronically by participants in clinical trials in a short amount of time.

Adult hydrocephalus comprises 4 pragmatic categories: (1) transition; (2) unrecognized congenital; (3) acquired; and (4) suspected idiopathic normal pressure hydrocephalus. Each of these groups has unique clinical presentations and care needs that require the involvement of adult neurosurgeons for diagnosis and treatment. Patients in all 4 of these categories benefit from longitudinal care for monitoring of their symptoms or assessing response to treatment.

In 1965, Hakim and Adams described 3 patients with normal pressure hydrocephalus who responded to treatment with a ventriculoatrial shunt. Afterward the adoption of shunt treatment without clear diagnostic criteria and surgical techniques resulted in poor outcomes with significant complications. The clinical practice guidelines for the diagnosis and treatment of idiopathic normal pressure hydrocephalus were first published by the Japanese Neurosurgical Society in 2004 and the international...
