Receptors of the large HER family play an important role in breast cancer, which is undergoing a gradual development in connection with biological development, both in the field of diagnostics and therapy. Dimerization of HER-2 with other HER members, such as HER-3, is the biggest driver of tumor cell growth and survival. Numerous studies show that HER-3 gene overexpression correlates with poor prognosis. ⋯ Our results showed amplification of HER-3 (CERB3) in 2 out of a sample of 20 patients with TNBC, and 13 of 20 HER-2‑positive patients. PD-L1 expression was demonstrated in 3 out of 13 HER-3‑positive patients and 2 out of 2 HER-3‑positive TNBC patients. There was a strong correlation between positive HER-3 and PD-L1 TNBC expression (p = Keywords: breast cancer, HER family, overexpression, HER-3, HER-2, PD-L1, TNBC.

Patent foramen ovale (PFO) is a risk factor of decompression sickness (DCS). However, data on risk stratification of divers with a PFO are sparse. This study sought to evaluate the risk of neurological DCS (DCSneuro), based on the presence and grade of a right-to-left shunt (RLS). ⋯ Divers with a RLS had a higher risk of DCSneuro and the risk increased with RLS grade. We suggest that TCD is an appropriate method for RLS screening and risk stratification in divers (Tab. 4, Fig. 2, Ref. 29).

Kidney carcinoma is currently the tenth most diagnosed tumour in women and the sixth in men. It makes up about 4 % of all malignant tumours. In urology, it is the third most common malignant disease. ⋯ Due to the expansion of diagnostic methods and the introduction of new techniques in surgical treatment, the paradigm in the surgical treatment of this disease has changed in recent years. In the case of a detailed study of the intracellular structures in the carcinogenic processes, the more profound knowledge about them can lead to the elimination of the need for surgical resection in future (Tab. 7, Fig. 4, Ref. 51).

Evaluation of the impact of surgical treatment on malignant transformation (MT) of adult supratentorial infiltrative grade II gliomas (G2G) in a series of chemotherapy and radiotherapy-naïve patients. ⋯ In our series, less extensive resections were associated with a shorter time to MT. Our data support an adoption of techniques enabling extensive G2G resections, such as intraoperative imaging and awake resections, into everyday routine (Tab. 1, Fig. 2, Ref. 40).

with the Dravet's syndrome phenotype are associated with the detection of a sequence variant in the SCN1A gene (alpha 1 subunit of the voltage-gated sodium channel) (2). However, sequence variants in the SCN1A gene are associated with a very broad clinical spectrum, from asymptomatic carriers to the severe myoclonic epilepsy phenotype with severe disease (3). ⋯ The aim of the analysis was to verify the extent, to which the storage of a pathogenic sequence variant in the SCN1A gene corresponds to the clinical picture of the patient (Tab. 2, Fig. 2, Ref. 10).
