Experimental Identification of Cross-Reacting IgG Hotspots to Predict Existing Immunity Evasion of SARS-CoV-2 Variants by a New Biotechnological Application of Phage Display.

Multiple pathogens are competing against the human immune response, leading to outbreaks that are increasingly difficult to control. For example, the SARS-CoV-2 virus continually evolves, giving rise to new variants. The ability to evade the immune system is a crucial factor contributing to the spread of these variants within the human population.

Correlation between COVID-19 severity and previous exposure of patients to Borrelia spp.

Predictors for the risk of severe COVID-19 are crucial for patient care and control of the disease. Other infectious diseases as potential comorbidities in SARS-CoV-2 infection are still poorly understood. Here we identify association between the course of COVID-19 and Lyme disease (borreliosis), caused by Borrelia burgdorferi transmitted to humans by ticks.

Dynamics of anti-SARS-CoV-2 seroconversion in individual patients and at the population level.

The immune response and specific antibody production in COVID-19 are among the key factors that determine both prognostics for individual patients and the global perspective for controlling the pandemics. So called "dark figure", that is, a part of population that has been infected but not registered by the health care system, make it difficult to estimate herd immunity and to predict pandemic trajectories. Here we present a follow up study of population screening for hidden herd immunity to SARS-CoV-2 in individuals who had never been positively diagnosed against SARS-CoV-2; the first screening was in May 2021, and the follow up in December 2021.

Hidden fraction of Polish population immune to SARS-CoV-2 in May 2021.

Population immunity (herd immunity) to SARS-CoV-2 derives from two sources: vaccinations or cases of infection with the virus. Infections can be diagnosed as COVID-19 and registered, or they can be asymptomatic, oligosymptomatic, or even full-blown but undiagnosed and unregistered when patients recovered at home. Estimation of population immunity to SARS-CoV-2 is difficult and remains a subject of speculations.

Studies of anions sorption on natural zeolites.

This work presents results of FT-IR spectroscopic studies of anions-chromate, phosphate and arsenate - sorbed from aqueous solutions (different concentrations of anions) on zeolites. The sorption has been conducted on natural zeolites from different structural groups, i.e.

Epidermal expression of I-TAC (Cxcl11) instructs adaptive Th2-type immunity.

To decipher early promoters of the local microenvironment for Th2-type immunity, we wanted to identify gene patterns that were induced by Leishmania major in the infected skin of susceptible, Th2-prone BALB/c, but not of resistant, Th1-prone C57BL/6 mice. We found a marked up-regulation of the chemokine I-TAC (Cxcl11) during the first 2 d of infection in the epidermis of susceptible but not of resistant mice. Accordingly, local injection of I-TAC (2×1 μg) in resistant mice on the first day of infection resulted in a Th2-driven, sustained deterioration of disease and dramatically enhanced parasite levels.

Soluble CD163 promotes recognition, phagocytosis and killing of Staphylococcus aureus via binding of specific fibronectin peptides.

CD163 is a multi-ligand scavenger receptor exclusively expressed by monocytes and macrophages, which is released after their activation during sepsis (sCD163). The biological relevance of sCD163, however, is not yet clear. We now demonstrate that sCD163 exhibits direct antimicrobial effects by recognizing a specific subfragment ((6) F1(1) F2(2) F2(7) F1) of fibronectin (FN) bound to staphylococcal surface molecules.

Endothelial cells present an innate resistance to glucocorticoid treatment: implications for therapy of primary vasculitis.

Background: In contrast to other chronic inflammatory diseases glucocorticoids alone do not maintain sufficient remission in primary vasculitis. The reasons for this therapeutic failure remain unclear.

Objectives: To investigate the molecular effects glucocorticoids exert on endothelial cells (EC) and to elucidate the molecular pathways responsible.

Induction of an anti-inflammatory human monocyte subtype is a unique property of glucocorticoids, but can be modified by IL-6 and IL-10.

Glucocorticoids (GC) are the most widely used immunosuppressive agents in clinical medicine. Recently we showed that GC enhance survival of human monocytes and induce a specific anti-inflammatory monocyte subtype which actively induces resolution of inflammation. We now investigated if cytokines IL-4, IL-6 and IL-10, which, like GC, have mostly anti-inflammatory effects on macrophages, would have GC-like effects also on monocytes.

Body posture and trunk muscle activity in women following treatment of breast cancer.

Background: Treatment of breast cancer can lead to abnormally shaped anteroposterior spinal curvatures, which consequently leads to functional disturbances of trunk muscles. The aim of the paper was to investigate the correlation between trunk muscle function and type of body posture in women receiving treatment for breast cancer.

Material And Methods: Fifty women following treatment of breast cancer were included in the study.

Body posture of women after breast cancer treatment.

Introduction: Human body posture changes in the course of ontogenesis. The changes are brought about by both internal factors (illness) and external factors (injury). The negative consequences of a medical condition such as breast cancer, together with the treatment process, undoubtedly contribute to disturbance of body posture.

Cerebral arterial stenoses and stroke: novel features of Aicardi-Goutières syndrome caused by the Arg164X mutation in SAMHD1 are associated with altered cytokine expression.

Aicardi-Goutières syndrome (AGS) is a rare inborn multisystemic disease, resembling intrauterine viral infection and resulting in psychomotor retardation, spasticity and chilblain-likeskin lesions. Diagnostic criteria include intracerebral calcifications and elevated interferon-alpha and pterin levels in cerebrospinal fluid (CSF). We report on four adult siblings with unknown neurodegenerative disease presenting with cerebrovascular stenoses, stroke and glaucoma in childhood, two of whom died at the age of 40 and 29 years.

The occurrence of strain symptoms in the lumbosacral region and pelvis during pregnancy and after childbirth.

Objective: The etiology and pathology of pain in the lumbosacral region and pelvis of pregnant women during and after pregnancy have not been fully determined. This study evaluated if lower back pain during pregnancy and after childbirth is connected with static alterations in the alignment of the pelvis, dysfunction of sacroiliac joints, and irritation of the pelvic ligaments and spine in the lumbosacral region.

Methods: This study was carried out on a group of 30 women in their eighth month of pregnancy and through 3 months after childbirth.

Glucocorticoids promote survival of anti-inflammatory macrophages via stimulation of adenosine receptor A3.

Active resolution of inflammation is a previously unrecognized process essential for tissue homeostasis. Monocytes play a pivotal role in the generation as well as resolution of inflammation. Glucocorticoids (GCs) are widely used anti-inflammatory agents.

Relation between trunk muscle activity and posture type in women following treatment for breast cancer.

The aim of the work was to determine the activity of trunk muscles in the sagittal plane in relation to body posture type in women treated for breast cancer. Fifty women having undergone treatment for breast cancer, with an average age of 61, participated in the study. All patients were studied by application of the photogrammetric method in order to determine posture; on the basis of the compensation ratio (mu), the examined group was divided into three posture sub-groups: kyphotic (K), lordotic (L) and balanced (R).

A comparison of the perceptions and aspirations of third-year physiotherapy students trained in three educational settings in Poland.

Objectives: In Poland, physiotherapy is offered at three types of school: medical universities, universities of physical education, and schools that do not specialise in either the medical sciences or physical education. This study explored the knowledge of students who were completing their physiotherapy studies about working in Poland and other countries of the European Union (EU), and about their vocational plans. Students were asked, through self-assessment, about aspects of the professional skills they had gained.
