Cytosolic phospholipase A2 in infiltrating monocyte derived macrophages does not impair recovery after spinal cord injury in female mice.

Spinal cord injury (SCI) leads to permanent motor and sensory loss that is exacerbated by intraspinal inflammation and persists months to years after injury. After SCI, monocyte-derived macrophages (MDMs) infiltrate the lesion to aid in myelin-rich debris clearance. During debris clearance, MDMs adopt a proinflammatory phenotype that exacerbates neurodegeneration and hinders recovery.

Nonresolving Neuroinflammation Regulates Axon Regeneration in Chronic Spinal Cord Injury.

Chronic spinal cord injury (SCI) lesions retain increased densities of microglia and macrophages. In acute SCI, macrophages induce growth cone collapse and facilitate axon retraction away from lesion boundaries. Little is known about the role of sustained inflammation in chronic SCI or whether chronic inflammation affects regeneration.

Non-resolving neuroinflammation regulates axon regeneration in chronic spinal cord injury.

Chronic spinal cord injury (SCI) lesions retain increased densities of microglia and macrophages. In acute SCI, macrophages induce growth cone collapse, facilitate axon retraction away from lesion boundaries, as well as play a key role in orchestrating the growth-inhibitory glial scar. Little is known about the role of sustained inflammation in chronic SCI, or whether chronic inflammation affects repair and regeneration.

Work loss and activity impairment due to extended nausea and vomiting in patients with breast cancer receiving CINV prophylaxis.

Purpose: Chemotherapy-induced nausea and vomiting (CINV)'s impact on work loss remains poorly described. We evaluated associations between the duration of CINV episodes, CINV-related work loss (CINV-WL), and CINV-related activity impairment (CINV-AI) in patients with breast cancer receiving highly emetogenic chemotherapy.

Methods: We analyzed data from a prospective CINV prophylaxis trial of netupitant/palonestron and dexamethasone for patients receiving an anthracycline and cyclophosphamide (AC) for breast cancer (NCT0340371).

PTEN knockout using retrogradely transported AAVs transiently restores locomotor abilities in both acute and chronic spinal cord injury.

Restoring function in chronic stages of spinal cord injury (SCI) has often been met with failure or reduced efficacy when regenerative strategies are delayed past the acute or sub-acute stages of injury. Restoring function in the chronically injured spinal cord remains a critical challenge. We found that a single injection of retrogradely transported adeno-associated viruses (AAVrg) to knockout the phosphatase and tensin homolog protein (PTEN) in chronic SCI can effectively target both damaged and spared axons and transiently restore locomotor functions in near-complete injury models.

Real-World Treatment Outcomes, Healthcare Resource Use, and Costs Associated with Antiemetics Among Cancer Patients on Cisplatin-Based Chemotherapy.

Introduction: Chemotherapy-induced nausea and vomiting (CINV) is a recognized adverse outcome among patients with cancer. This retrospective study aimed to quantify the treatment outcomes, resource utilization, and costs associated with antiemetic use to prevent CINV in a broad US population who received cisplatin-based chemotherapy.

Methods: Data from the STATinMED RWD Insights Database was collected from January 1, 2015 to December 31, 2020.

Process development of a SARS-CoV-2 nanoparticle vaccine.

One of the outcomes from the global COVID-19 pandemic caused by SARS-CoV-2 has been an acceleration of development timelines to provide treatments in a timely manner. For example, it has recently been demonstrated that the development of monoclonal antibody therapeutics from vector construction to IND submission can be achieved in five to six months rather than the traditional ten-to-twelve-month timeline using CHO cells [1], [2]. This timeline is predicated on leveraging existing, robust platforms for upstream and downstream processes, analytical methods, and formulation.

The high intensity diffractometer for residual stress analysis (HIDRA), a third generation residual stress mapping neutron diffractometer at the high flux isotope reactor.

This paper describes the hardware and software upgrades, operation, and performance of the high intensity diffractometer for residual stress analysis (HIDRA) instrument, a residual stress mapping neutron diffractometer located at the High Flux Isotope Reactor at Oak Ridge National Laboratory in Oak Ridge Tennessee, USA. Following a major upgrade in 2018, the new instrument has a single He multiwire 2D 30 × 30 cm position sensitive detector, yielding a field of view of 17° 2θ. The increase in the field of view (from 4° 2θ) from the previous model instrument has contributed to the tremendous improvement in the out of plane solid angle such that the 3D count rate could be obtained easily.

Bobbitt's Salt-Mediated Oxidation of Alkynyl-ols and -diols to the Corresponding Aldehydes and Their Application in Tandem Reactions.

Propargyl alcohol derivatives were readily oxidized using Bobbitt's salt to yield the corresponding propynal products. 2-Butyn-1,4-diol may be selectively oxidized to provide either 4-hydroxy-2-butynal or acetylene dicarboxaldehyde, and the resulting stable dichloromethane solutions containing the chemically sensitive acetylene aldehydes were used directly in subsequent Wittig, Grignard, or Diels-Alder reactions. This method provides safe and efficient access to propynals and allows the preparation of polyfunctional acetylene compounds from readily accessible starting material without the use of protecting groups.

The applicability of species sensitivity distributions to the development of generic doses for phytosanitary irradiation.

Ionizing radiation is used as a phytosanitary treatment to prevent the introduction of pests through trade. Generic doses are a valuable means to increase the number of pest-commodity combinations that can be treated using phytosanitary irradiation. Generic doses allow for the treatment of the entire taxa for which the dose has been approved, allowing for the treatment of untested species.

Antiemetic use and chemotherapy induced nausea and vomiting related hospitalization costs after highly or moderately emetogenic chemotherapy.

Despite numerous available antiemetics, chemotherapy induced nausea and vomiting (CINV) still affects many patients, and CINV related hospitalizations and costs often result. PrecisionQ analyzed its database to evaluate CINV related hospitalizations and costs following antiemetics use including netupitant/fosnetupitant with palonosetron (NEPA), aprepitant/fosaprepitant with ondansetron (APON) or aprepitant/fosaprepitant with palonosetron (APPA) in patients receiving highly emetogenic chemotherapy or moderately emetogenic chemotherapy. Database analysis identified 15,583 patient records (807 NEPA, 2023 APON, 12,753 APPA) and mean CINV related hospitalization costs were lower across all patients receiving NEPA (US$301) compared with patients receiving APON ($1006, p < 0.

Plasma biomarkers TAP, CPA1, and CPA2 for the detection of pancreatic injury in rat: the development of a novel multiplex IA-LC-MS/MS assay and biomarker performance evaluation.

Drug-induced pancreatic injury (DIPI) is an issue seen in drug development both in nonclinical and clinical contexts. DIPI is typically monitored by measurement of lipase and/or amylase, however, both enzymes lack sensitivity and specificity. Although candidate protein biomarkers specific to pancreas exist, antibody-based assay development is difficult due to their small size or the rapid cleavage by proteolytic enzymes released during pancreatic injury.

Endovascular management of extensive iliocaval thrombosis secondary to synchronous uterine myoma compression and May-Thurner syndrome.

This report presents a 42-year-old African American woman with bilateral lower extremity pain, swelling, and paresthesias. Imaging demonstrated a large fibroid uterus with a mass effect in proximity to an iliocaval venous thrombosis. Mechanical thrombectomy was performed with recurrent infrarenal vena cava and bilateral iliac thrombosis, prompting hysterectomy.

Advanced Age and Neurotrauma Diminish Glutathione and Impair Antioxidant Defense after Spinal Cord Injury.

Advanced age at the time of spinal cord injury (SCI) exacerbates damage from reactive oxygen species (ROS). Mechanisms underlying this age-dependent response are not well understood and may arise from decreased antioxidant defense. We investigated how spinal cord levels of the antioxidant glutathione (GSH), and its regulation, change with age and SCI.

Immunoglobulin G Is Increased in the Injured Spinal Cord in a Sex- and Age-Dependent Manner.

There are limited studies examining age and sex as biological variables in the pathophysiology of spinal cord injury (SCI). The use of older animals and sex-balanced groups in SCI models is increasingly prioritized to better match clinical demographics. Including older animals in SCI studies is technically challenging, and outcomes are unpredictable with respect to biological and treatment responses.

Universal Accessible Biomarkers of Drug-Induced Tissue Injury and Systemic Inflammation in Rat: Performance Assessment of TIMP-1, A2M, AGP, NGAL, and Albumin.

The ability to monitor for general drug-induced tissue injury (DITI) or systemic inflammation in any tissue using blood-based accessible biomarkers would provide a valuable tool in early exploratory animal studies to understand potential drug liabilities. Here we describe the evaluation of 4 biomarkers of tissue remodeling and inflammation (α2-macroglobulin [A2M], α1-acid glycoprotein [AGP], neutrophil gelatinase-associated lipocalin [NGAL], and tissue inhibitor of metalloproteinases [TIMP-1]) as well as the traditional serum parameter albumin as potential blood-based biomarkers of DITI and systemic inflammatory response (SIR). Biomarker performance was assessed in 51 short-term rat in vivo studies with various end-organ toxicities or SIR and receiver operating characteristic curves were generated to compare relative performances.

Geographical Distribution and Genetic Diversity of the Banana Fusarium Wilt Fungus in Laos and Vietnam.

Fusarium wilt, caused by the fungus f. sp. (Foc), poses a major threat to global banana production.

Materials And Methods: This prospective, randomized, double-blinded clinical trial included 60 men who were randomly assigned to LIESWT (n=30, active group) or placebo (n=30) over 6 weeks. Patient demographics, change in International Index of Erectile Function (IIEF)-5, Erection Hardness Score (EHS) and Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) scores, and an overall satisfaction score (on a 5-point scale), were recorded.

Abdominal and perineal hernia rates following vertical rectus abdominis myocutaneous (VRAM) flap reconstruction - a supraregional experience.

Background: Vertical rectus abdominis myocutaneous (VRAM) flap has proven to be a robust reconstruction method following radical pelvic surgery. Radical pelvic surgery is associated with high morbidity due to pelvic complications and non-healing perineal wounds, as a result of non-collapsible pelvic dead space and pre-operative adjuvant radiotherapy insult. VRAM flap reconstruction addresses both issues by obliterating the dead space and introducing healthy non-radiated tissue.

Association of Race and Risk of Future Scleroderma Renal Crisis at Systemic Sclerosis Diagnosis.

Objective: Scleroderma renal crisis (SRC) is a rare and severe manifestation of systemic sclerosis (SSc). Although it is well documented that Black patients with SSc have worse morbidity and mortality than non-Black patients, racial predilection for SRC is underreported. We examine the association of race and future development of SRC in an SSc cohort.

Live Viral Vaccine Neurovirulence Screening: Current and Future Models.

Live viral vaccines are one of the most successful methods for controlling viral infections but require strong evidence to indicate that they are properly attenuated. Screening for residual neurovirulence is an important aspect for live viral vaccines against potentially neurovirulent diseases. Approximately half of all emerging viral diseases have neurological effects, so testing of future vaccines will need to be rapid and accurate.
