Surviving the Storm: Challenges of Bladder Cancer Care During the COVID-19 Pandemic.

Purpose: To evaluate the impact of the COVID-19 pandemic on the care of patients with bladder cancer in a tertiary oncology center.

Materials And Method: We performed a retrospective analysis of patients admitted to a tertiary cancer center for the treatment of bladder cancer between 2019 and 2022. Surgical volumes, patient demographics, clinical characteristics, and postoperative outcomes were compared across these years.

High-Throughput IgG Epitope Mapping of Tetanus Neurotoxin: Implications for Immunotherapy and Vaccine Design.

Tetanus is an acute, fatal disease caused by exotoxins released from during infections. A protective humoral immune response can be induced by vaccinations with pediatric and booster combinatorial vaccines that contain inactivated tetanus neurotoxin (TeNT) as a major antigen. Although some epitopes in TeNT have been described using various approaches, a comprehensive list of its antigenic determinants that are involved with immunity has not been elucidated.

B-Cell Epitope Mapping of the Toxins A, B, and P and an ELISA Assay.

Oral immunization with the choleric toxin (CT) elicits a high level of protection against its enterotoxin activities and can control cholera in endemic settings. However, the complete B-cell epitope map of the CT that is responsible for protection remains to be clarified. A library of one-hundred, twenty-two 15-mer peptides covering the entire sequence of the three chains of the CT protein (CTP) was prepared by SPOT synthesis.

Epitope Mapping of the Diphtheria Toxin and Development of an ELISA-Specific Diagnostic Assay.

The diphtheria toxoid antigen is a major component in pediatric and booster combination vaccines and is known to raise a protective humoral immune response upon vaccination. Although antibodies are considered critical for diphtheria protection, little is known about the antigenic determinants that maintain humoral immunity. One-hundred and twelve 15 mer peptides covering the entire sequence of diphtheria toxin (DTx) protein were prepared by SPOT synthesis.

The obturator oblique and iliac oblique/outlet views predict most accurately the adequate position of an anterior column acetabular screw.

Objective: Percutaneous fixation of the acetabulum is a treatment option for select acetabular fractures. Intra-operative fluoroscopy is required, and despite various described imaging strategies, it is debatable as to which combination of fluoroscopic views provides the most accurate and reliable assessment of screw position.

Materials And Methods: Using five synthetic pelvic models, an experimental setup was created in which the anterior acetabular columns were instrumented with screws in five distinct trajectories.

Clinical outcomes of arthroscopic rotator cuff repair: correlation between the University of California, Los Angeles (UCLA) and American Shoulder and Elbow Surgeons (ASES) scores.

Background: There are more than 40 outcome scores for evaluating shoulder pain and function. Some studies have correlated the results obtained using different scales, but none has compared the results obtained by the University of California, Los Angeles (UCLA) and American Shoulder and Elbow Surgeons (ASES) scores.

Methods: We performed a retrospective study to evaluate patients who underwent arthroscopic rotator cuff repair with 2 years' follow-up.

Genome characterization of a bovine papillomavirus type 5 from cattle in the Amazon region, Brazil.

Papillomaviruses are small and complex viruses with circular DNA genome that belongs to the Papillomavirus family, which comprises at least 39 genera. The bovine papillomavirus (BPV) causes an infectious disease that is characterized by chronic and proliferative benign tumors that affect cattle worldwide. In the present work, the full genome sequence of BPV type 5, an Epsilonpapillomavirus, is reported.

Novel Bovine Papillomavirus Type Discovered by Rolling-Circle Amplification Coupled with Next-Generation Sequencing.

Currently, fifteen bovine papillomavirus (BPV) types have been identified and classified into four genera: Deltapapillomavirus, Epsilonpapillomavirus, Dyoxipapillomavirus, and Xipapillomavirus. Here, the complete genome sequence of a new BPV type (BPV 04AC14) recovered from a papillomatous lesion is reported. The genome is 7,282 bp in length and exhibits the classic genetic organization and motifs of the members of Papillomaviridae.

Genetic characterization of Amazonian bovine papillomavirus reveals the existence of four new putative types.

Papillomaviruses are small and complex viruses that belong to the Papillomaviridae family, which comprises 39 genera. The bovine papillomavirus (BPV) causes an infectious disease that is characterized by chronic and proliferative benign tumors that affect cattle worldwide. Different genotypes of BPVs can cause distinct skin and mucosal lesions and the immunity they raise has low cross-protection.

Identification of linear B epitopes of pertactin of Bordetella pertussis induced by immunization with whole and acellular vaccine.

Pertussis is a serious infectious disease of the respiratory tract caused by the gram-negative bacteria Bordetella pertussis. There has been a reemergence of this disease within the population of several countries that have well established vaccination programs. Analyzes of clinical isolates suggest an antigenic divergence between the vaccine-based strains to the circulating strains.
