Comparison Between Two Volumes of 70% Alcohol in Single Injection Ultrasound-Guided Celiac Plexus Neurolysis: A Randomized Controlled Trial.

Background: Pain due to inoperable upper abdominal malignancies is a challenging condition that needs a multimodal analgesic regimen to be managed properly. Celiac plexus alcohol neurolysis was proved to be effective in relieving such type of pain; however, there is no consistent data about the optimal volume to be used to maintain the balance between the neurolytic effect and the destructive effect of alcohol.

Objectives: We aim to compare the analgesic effect of 2 different volumes of alcohol to improve the outcome of interventional management.

Preoperative duloxetine on postoperative pain after laparoscopic gynecological surgeries: A systematic review and meta-analysis of randomized controlled trials.

Objective: To evaluate the efficacy and safety of preoperative duloxetine on postoperative pain management after gynecologic laparoscopic surgeries.

Methods: A systematic search was done in Cochrane Library, PubMed, ISI web of science, and Scopus from inception to September 2021. We selected randomized clinical trials (RCTs) that compared preoperative duloxetine (intervention group) versus placebo (control group) among women undergoing gynecologic laparoscopic surgeries.

Saponin-adjuvanted vaccine protects chickens against velogenic Newcastle disease virus.

Despite extensive vaccination campaigns, Newcastle disease virus (NDV) remains endemic in many countries worldwide, and factors that contribute to this failure include mismatched vaccines, partial immunization, and poor husbandry practices. In order to overcome the problem of genetic divergence between circulating field strains and vaccine strains, we saponin-adjuvanted an Egyptian field strain and assessed its safety and immunogenicity in chickens. Immunization of chickens with the vaccine followed by challenge with a velogenic reference strain revealed the potential of the saponin-adjuvanted vaccine to induce a strong immune response that resulted in complete protection of chickens.

Oral administration of hyperimmune IgY: an immunoecological approach to curbing acute infectious bursal disease virus infection.

Infectious bursal disease (IBD) is one of the most important viral diseases of poultry. Hygienic management and proper vaccination are currently the only economic approach for control of this disease. Attempts have been made to control the disease after the onset of an outbreak using parenteral administration of hyperimmune IgY preparations.

Extensive antigenic changes in an atypical isolate of very virulent infectious bursal disease virus and experimental clinical control of this virus with an antigenically classical live vaccine.

The 99323 Egyptian isolate of infectious bursal disease (IBD) virus (IBDV) was identified during an international survey of acute IBD cases. Its unique antigenicity was characterized by a markedly reduced binding of neutralizing monoclonal antibodies 3, 4, 5, 6, 8 and 9 in an antigen-capture enzyme-linked immunosorbent assay. Nucleotide sequencing of the genome region encoding the VP2 major immunogenic domain in 99323 revealed amino acid changes occurring at positions critical for antigenicity, but phylogenetic analysis demonstrated that 99323 was related to typical, very virulent IBDV (e.
