Hypothalamic orexins as possible therapeutic agents in threat and spatial memory disorders.

Orexin-A and orexin-B, neuropeptides produced exclusively in the lateral hypothalamus, have been implicated in various functions, including memory. Their levels are elevated in certain pathological states, such as PTSD, and lowered in other states, e.g.

Remodeling of Retinal Arterioles and Carotid Arteries in Heart Failure Development-A Preliminary Study.

Current data indicate that heart failure (HF) is associated with inflammation and microvascular dysfunction and remodeling. These mechanisms could be involved in HF development and progression, especially in HF with preserved ejection fraction (HFpEF). We aimed to compare structural changes in retinal arterioles and carotid arteries between HF patients and patients without heart failure.

The aims of our study are: to determine the state of smoke-free practices in Polish hospitals, and to identify challenges facing hospitals implementing smoke-free practices.

Material And Methods: In 2018, a cross-sectional survey was conducted on a representative sample of 100 hospitals operating in Poland.

EVI1 as a Prognostic and Predictive Biomarker of Clear Cell Renal Cell Carcinoma.

The transcription factor EVI1 plays an oncogenic role in several types of neoplasms by promoting aggressive cancer features. EVI1 contributes to epigenetic regulation and transcriptional control, and its overexpression has been associated with enhanced PI3K-AKT-mTOR signaling in some settings. These observations raise the possibility that EVI1 influences the prognosis and everolimus-based therapy outcome of clear cell renal cell carcinoma (ccRCC).

Prevalence of Chronic Pain, Particularly with Neuropathic Component, and Its Effect on Overall Functioning of Elderly Patients.

BACKGROUND The prevalence of chronic pain among the elderly is high (estimated at 25-85%) and may adversely affect their everyday functioning, although it is often unrecognized. MATERIAL AND METHODS The aim of this study was to assess the prevalence of chronic pain, especially with the neuropathic component, and its effect on overall functioning of elderly patients. We enrolled 145 subjects older than 60 years (nursing home residents, or patients of outpatient geriatric clinic).

Epidemiological Survey and Retrospective Analysis of Infections between 2000 and 2017 in Warmia and Masuria Voivodship in Poland.

: Salmonellosis is a major foodborne bacterial infection throughout the world. Epidemiological surveillance is one of the key factors to reduce the number of infections caused by this pathogen in both humans and animals. The first outcome measure was the prevalence of non-typhoid (NTS) infections between 2000 and 2017 among the population of the predominantly agricultural and touristic Polish region of Warmia and Masuria (WaM).

Daily oligofructose-enriched inulin intake impacts bone turnover markers but not the cytokine profile in pediatric patients with celiac disease on a gluten-free diet: Results of a randomised, placebo-controlled pilot study.

Background: Bone metabolism disturbances are commonly observed in patients with newly diagnosed celiac disease (CD). The only available treatment for CD-the intake of a gluten-free diet (GFD)-has been found to be insufficient in effectively improving bone health in some patients. Therefore, there is an urgent need to modify the GFD so as to allow for the provision of all the necessary nutrients and improved absorption.

LPAR2 and LPAR4 are the Main Receptors Responsible for LPA Actions in Ovarian Endometriotic Cysts.

Endometriosis has been considered as an estrogen (E2)-dependent and progesterone (P4)-resistant disease. On the other hand, lysophosphatidic acid (LPA) has been suggested as a significant modulator of ovarian pathology, acting via both LPA levels and LPA receptor (LPAR) upregulation. Therefore, the objective of the present study was to evaluate LPA concentration as well as LPARs, autotaxin (ATX), and phospholipase A2 (PLA2) expression in ovarian endometriotic cysts and normal endometrium with correlation of the expression of E2 and P4 receptors in endometriotic cysts.

Altered expression of lysophosphatidic acid receptors, in association with the synthesis of estrogens and androgens in type 1 endometrial cancer biology.

To establish association between two main lysophosphatidic acid (LPA) receptors (LPAR2 and LPAR1) with the synthesis of estrogens and androgens in type-1 endometrial carcinoma (EC), we evaluated correlation of LPARs expression with expression of steroid 5 alpha-reductase 2 - aromatase (SRD5A2), or cytochrome P450 family 19 subfamily A member 1-5α-reductase (CYP19A1) in EC. Moreover, we aimed to investigate SRD5A2 and CYP19A1 expression in type 1 endometrial cancer and normal endometrium with its correlation to selected clinicopathological features. The studied cancerous samples showed higher CYP19A1 and SRD5A2 expression comparing to normal endometria.

When do paediatric patients with familial hypercholesterolemia need statin therapy?

Introduction: Familial hypercholesterolemia (FH) is one of the most common autosomal dominant disorders. It is characterized by elevated LDL cholesterol levels occurring already by early childhood. Awareness of health risks in FH patients should incite health professionals to actively seek and treat children with lipid disorders to reduce their risk of myocardial infarction and stroke.

Food Protein-Induced Enterocolitis Syndrome.

Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-, cell-mediated food allergy of unknown prevalence and pathophysiology. Onset is typically during the first year of life; seafood-induced FPIES may start in adulthood. Acute FPIES manifests within 1-4 hours after ingestion with repetitive emesis, pallor, and lethargy progressing to dehydration and hypovolemic shock in 15% of cases.

The significance of the altered expression of lysophosphatidic acid receptors, autotaxin and phospholipase A2 as the potential biomarkers in type 1 endometrial cancer biology.

In order to study lysophosphatidic acid (LPA) signaling associated with type 1 endometrial carcinoma (EC), we evaluated the LPA receptors (LPARs), autotaxin (ATX) and phospholipase A2 (PLA2) expression in EC and normal endometrium with correlation to clinicopathological features. We investigated LPAR1, LPAR2, LPAR3, LPAR4, ATX and PLA2 expression at mRNA and protein levels using quantitative real-time PCR and western blot analyses in 37 ECs and 10 normal endometria. All the examined LPARs (except for LPAR3 protein), ATX and PLA2 were overexpressed in cancerous compared to healthy endometrium.

Rhabdomyosarcoma of the head and neck in children.

Rhabdomyosarcoma (RMS) is the most frequent soft tissue sarcoma in children. It is localized in the head and neck region in 40% of cases. Treatment of RMS is complex, including multi-drug chemotherapy, radiotherapy and surgery.

Lysophosphatidic acid (LPA) signaling in human and ruminant reproductive tract.

Lysophosphatidic acid (LPA) through activating its G protein-coupled receptors (LPAR 1-6) exerts diverse cellular effects that in turn influence several physiological processes including reproductive function of the female. Studies in various species of animals and also in humans have identified important roles for the receptor-mediated LPA signaling in multiple aspects of human and animal reproductive tract function. These aspects range from ovarian and uterine function, estrous cycle regulation, early embryo development, embryo implantation, decidualization to pregnancy maintenance and parturition.

Bisphenol A alters β-hCG and MIF release by human placenta: an in vitro study to understand the role of endometrial cells.

A proper fetomaternal immune-endocrine cross-talk in pregnancy is fundamental for reproductive success. This might be unbalanced by exposure to environmental chemicals, such as bisphenol A (BPA). As fetoplacental contamination with BPA originates from the maternal compartment, this study investigated the role of the endometrium in BPA effects on the placenta.

Adrenal incidentaloma imaging - the first steps in therapeutic management.

The term "adrenal incidentaloma" refers to clinically unapparent adrenal mass detected during imaging examination performed for reasons other than the evaluation of adrenal glands. These tumors must be carefully examined in order to assess the indications for surgical treatment. The main method of finding evidence of potential malignancy in these lesions is computed tomography (CT), before and after i.
