[Complications after administration of mRNA vaccine against COVID-19 - case report and short review].

The pandemic of the disease COVID-19 (COronaVIrus Disease 2019) caused by the SARS-CoV-2 coronavirus (severe acute respiratory syndrome coronavirus 2) resulted in millions of deaths and many patients have chronic consequences after overcoming the acute condition. Several vaccines have been developed in an effort to stop the spread of the virus, but they have potentially serious adverse effects. We present a case report of a patient with acute (myocarditis, exacerbation of bronchial asthma) and long-term (postural orthostatic tachycardia syndrome - POTS) complications after vaccination with the second dose of mRNA vaccine BNT162b2 (Comirnaty®).

The influence of obesity on early outcomes in primary hip arthroplasty.

Obesity is considered an independent risk factor for adverse outcome after arthroplasty surgery. Data on 191 consecutive total hip arthroplasties were prospectively collected. Body mass index (BMI) was calculated for each patient and grouped into nonobese (BMI <30 kg/m(2)), obese (BMI 30-34.

[Changes in membrane enzymes in warm liver ischemia].

Background: The aim of the study is to perform a morphological analysis of certain membrane enzymes and parenchymal alterations during warm ischemia in the pig liver.

Methodology: Standard hepatectomies were performed in a set of 24 pigs. Intraoperative intravenous (portal vein) hydroxyl radical scavenger Stobadine and Pentoxifylline was administered.

Warm liver ischemia in experiment and lysosomal markers.

Background: The aim of the study is to perform a morphological analysis of certain lysosomal enzymes and parenchymal alterations during warm ischemia in the pig liver.

Methods: Standard hepatectomies were performed in a set of 24 pigs. Intra-operative intravenous (portal vein) Pentoxiphylline and hydroxyl radical scavenger Stobadine was administered.

Conformation study of the membrane models by the Maxwell displacement current technique and oxidative stress.

The role of biological membranes as a target in biological radiation damage is still unclear. Recently much attention has been paid to the dynamic behaviour of the cell membrane. Maxwell displacement current technique (MDC) provides new possibility of conformation study of the membrane models.
