COVID-19 vaccine BNT162b1 elicits human antibody and T1 T cell responses.

An effective vaccine is needed to halt the spread of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic. Recently, we reported safety, tolerability and antibody response data from an ongoing placebo-controlled, observer-blinded phase I/II coronavirus disease 2019 (COVID-19) vaccine trial with BNT162b1, a lipid nanoparticle-formulated nucleoside-modified mRNA that encodes the receptor binding domain (RBD) of the SARS-CoV-2 spike protein. Here we present antibody and T cell responses after vaccination with BNT162b1 from a second, non-randomized open-label phase I/II trial in healthy adults, 18-55 years of age.

p53 and TAp63 promote keratinocyte proliferation and differentiation in breeding tubercles of the zebrafish.

p63 is a multi-isoform member of the p53 family of transcription factors. There is compelling genetic evidence that ΔNp63 isoforms are needed for keratinocyte proliferation and stemness in the developing vertebrate epidermis. However, the role of TAp63 isoforms is not fully understood, and TAp63 knockout mice display normal epidermal development.

Pure bipolar plasma vaporization of the prostate: the Zürich experience.

Introduction And Objectives: Bipolar plasma vaporization (BPV) has been introduced as an alternative to transurethral resection of the prostate (TURP). Promising short-term results, but inferior mid-term results compared to TURP have been reported following first-generation bipolar electrovaporization. Outcome data following second-generation BPV are still scarce.

Kindlin-1 mutant zebrafish as an in vivo model system to study adhesion mechanisms in the epidermis.

From a forward genetic screen for epidermal defects in zebrafish, we identified a loss-of-function mutation in Kindlin-1, an essential regulator of integrin function. The mutation generates a premature stop codon, deleting the integrin-binding site. The mutant zebrafish develops cell-matrix and cell-cell adhesion defects in the basal epidermis leading to progressive fin rupturing, and was therefore designated rupturing-of-fins (rof).

Preperitoneal robotic prostate adenomectomy.

Objectives: To describe the surgical technique and evaluate the feasibility of robotic-assisted preperitoneal prostate adenomectomy for large benign adenomas in a pilot series.

Methods: A total of 13 consecutive patients with a median age 70 years and body mass index of 26 kg/m(2) in whom open adenomectomy was planned were included in this pilot study. The extraperitoneal robotic approach was standardized in all cases.

Complications of robotic assisted radical prostatectomy.

Objectives: Robotic radical prostatectomy claims optimal oncologic results, minimal morbidity and best outcomes of urinary continence and erection function. Potential benefits concerning side effects and complications compared to open radical prostatectomy are analysed.

Methods: Out of 450 robotic radical prostatectomies performed, the last 210 patients aged 64 (41-78), PSA of 7.
