is a Gram-negative bacterium that is the causative agent of the respiratory disease known as pertussis. Since the switch to the acellular vaccines of DTaP and Tap, pertussis cases in the US have risen and cyclically fallen. We have observed that mRNA pertussis vaccines are immunogenic and protective in mice.

Currently, inconsistent methodologies are employed by researchers across the globe, making it difficult to compare findings. The objective of this work was to utilize the CD-1 mouse model with two routes of challenge, intranasal and aerosol administration of B.

A secondary analysis was conducted using a nonprobability sample, the 2017 , based on 10,027 youth who reported their marijuana use behaviors and state of residence. Random intercept multilevel models were estimated to account for between- and within-state variability.

Limited data exists among BLMSM on the impact of substance use at different stages of the PrEP Care Cascade. We examined the ways substance (alcohol, cannabis, other drug) use is related to PrEP experiences across the PrEP Care Cascade (PrEP aware/no use; PrEP use/discontinuation; PrEP use/adherent).

All current WHO approved COVID-19 vaccines are administered through the muscular route. We have developed a prototype two-dose vaccine (BReC-CoV-2) by combining the Receptor Binding Domain (RBD) antigen, via conjugation to Diphtheria toxoid (EcoCRM).

The purpose of this study was to extend previous research focused on adult- and LGBTQ-specific structural factors (e.g.
View Article and Find Full Text PDFAlthough scholarship continues to document higher rates of alcohol use for sexual and gender minority (SGM) youth compared with heterosexual and cisgender youth, research identifying factors that mitigate SGM youths' risk is nascent. Youth spend substantial time in schools; therefore, teachers could play significant roles in attenuating these health concerns. We used data from a nationwide survey of 11,189 SGM youth (M = 15.

This report describes the population pharmacokinetics of clofarabine and its metabolite 6-ketoclofarabine in adult and pediatric patients with hematologic malignancies or solid tumors. Clofarabine pharmacokinetics were best described by a 2-compartment model with linear elimination and first-order absorption after oral administration.

Methods: This phase II, open label, single arm study was conducted to evaluate the safety and efficacy of 75-100 mg/m2 cisplatin combined with 300-400 mcg talabostat bid for 6, 21-day cycles.
RLIP76 is a multifunctional membrane protein that transports glutathione conjugates of electrophilic compounds and other xenobiotics including chemotherapy agents out of cells. The protein is overexpressed in lung carcinomas, ovarian carcinomas, and melanomas. The protein also binds Ral and participates in mitotic spindle function, clathrin-dependent endocytosis, and triggers GTPase-activating protein activity.

This phase 1 study was designed to characterize the toxicity, pharmacokinetics and preliminary antitumor activity associated with OncoGel administered directly into solid tumors. OncoGel was injected into 18 superficially accessible advanced solid cancerous lesions among 16 adult patients for whom no curative therapy was available.

This dose-escalation study was conducted to evaluate the safety of PT-100 in patients receiving myelosuppressive chemotherapy and to assess its effects on neutrophil recovery.PT-100 was administered orally for 7 days as a 200 microg, 400 microg, 800 microg, or 1,200 microg total daily dose (divided twice daily) to 6, 6, 17, and 5 patients, respectively.

Patients And Methods: We performed a randomized, dose-variable, phase II trial involving stages II, IIIA, IIIB, and IV non-small-cell lung cancer patients. Each patient received one of three doses (1.
L523S is an immunogenic lung cancer antigen that has demonstrated preclinical safety when the gene is injected intramuscularly as an expressive plasmid (pVAX/L523S) and when delivered following incorporation into an E1B-deleted adenovirus (Ad/L523S). We performed a phase I clinical trial in 13 stage IB, IIA, and IIB non-small-cell lung cancer patients. pVAX/L523S (8 mg on days 0 and 14 in all cohorts) and Ad/L523S (1, 20, 400 x 10(9) vp on days 28 and 56, cohorts 1, 2, and 3, respectively) were administered to 3 patients in each of three cohorts.

Patients And Methods: Twenty-two adult patients with advanced solid tumors were treated in this dose escalation study. Patients were treated every 21 days with CT-2103 at 175, 210, 225, or 250 mg/m2 (doses expressed as units of conjugated-paclitaxel) via 10-20 minute intravenous (IV) infusion, followed one hour later with carboplatin administered at AUC 5 or 6 via 30 minute IV infusion.

Many of these studies demonstrated dose-limiting systemic side effects from high concentrations of TNF-alpha. The recent focus has been on developing a local delivery system for TNF-alpha to minimize the systemic response.

The mda-7 gene (approved gene symbol IL24) is a novel tumor suppressor gene with tumor-apoptotic and immune-activating properties. We completed a Phase I dose-escalation clinical trial, in which a nonreplicating adenoviral construct expressing the mda-7 transgene (INGN 241; Ad-mda7) was administered intratumorally to 22 patients with advanced cancer. Excised tumors were evaluated for vector-specific DNA and RNA, transgenic MDA-7 expression, and biological effects.
