The impact of age, sex, comorbidities, and use of antithrombotics on the clinical course severity among patients surgically treated for urinary bladder tamponade.

Objectives: To examine the relationship between clinical patient characteristics and the severity of the disease course in patients hospitalized due to urinary bladder tamponade. The severity was assessed based on hemoglobin (Hgb) levels upon admission, the requirement for red blood cell transfusion (RBCT), and length of hospital stay.

Materials And Methods: A retrospective analysis was conducted at a single center, involving 75 patients who were hospitalized due to urinary bladder tamponade.

The impact of antithrombotic therapy on the time of detection of bladder cancer.

Introduction: The aim of this article was to investigate the impact of chronic antithrombotic therapy (AT) use on the time of detection of bladder cancer, assuming that patients taking AT experience episodes of macroscopic hematuria earlier, and therefore have a more favorable histopathological grade and stage, as well as a smaller number and size of tumors compared to patients not taking AT.

Material And Methods: A retrospective, cross-sectional study was conducted, including 247 patients who underwent bladder cancer surgery for the first time at our institution during the three-year period (2019-2021) and who experienced macroscopic hematuria.

Results: A lower frequency of high-grade bladder cancer (40.

Influence of the grade and invasiveness of bladder cancer on disease course severity in patients with bladder tamponade resulting from a bleeding bladder cancer.

Introduction And Objectives: Urinary bladder tamponade is a common urological emergency, but it has so far been insufficiently researched. The aim of our study was to show the association between the characteristics of bladder cancer (grade and invasiveness) and disease course severity based on blood hemoglobin (Hgb) count at admission, the need for red blood cell transfusion (RBCT), and the length of hospitalization in patients suffering from bladder tamponade.

Materials And Methods: A retrospective, cross-sectional study was conducted, namely, including 25 adult patients surgically treated for bladder tamponade resulting from a bleeding bladder cancer.

Melittin induced cytogenetic damage, oxidative stress and changes in gene expression in human peripheral blood lymphocytes.

Melittin (MEL) is the main constituent and principal toxin of bee venom. It is a small basic peptide, consisting of a known amino acid sequence, with powerful haemolytic activity. Since MEL is a nonspecific cytolytic peptide that attacks lipid membranes thus leading to toxicity, the presumption is that it could have significant therapeutic benefits.

In female rats, ethylene glycol treatment elevates protein expression of hepatic and renal oxalate transporter sat-1 (Slc26a1) without inducing hyperoxaluria.

Aim: To investigate whether the sex-dependent expression of hepatic and renal oxalate transporter sat-1 (Slc26a1) changes in a rat model of ethylene glycol (EG)-induced hyperoxaluria.

Methods: Rats were given tap water (12 males and 12 females; controls) or EG (12 males and 12 females; 0.75% v/v in tap water) for one month.

Ileal Interposition in Rats with Experimental Type 2 Like Diabetes Improves Glycemic Control Independently of Glucose Absorption.

Bariatric operations in obese patients with type 2 diabetes often improve diabetes before weight loss is observed. In patients mainly Roux-en-Y-gastric bypass with partial stomach resection is performed. Duodenojejunal bypass (DJB) and ileal interposition (IIP) are employed in animal experiments.

Sex-dependent expression of water channel AQP1 along the rat nephron.

In the mammalian kidney, nonglycosylated and glycosylated forms of aquaporin protein 1 (AQP1) coexist in the luminal and basolateral plasma membranes of proximal tubule and descending thin limb. Factors that influence AQP1 expression in (patho)physiological conditions are poorly known. Thus far, only angiotensin II and hypertonicity were found to upregulate AQP1 expression in rat proximal tubule in vivo and in vitro (Bouley R, Palomino Z, Tang SS, Nunes P, Kobori H, Lu HA, Shum WW, Sabolic I, Brown D, Ingelfinger JR, Jung FF.

Localizations of Na(+)-D-glucose cotransporters SGLT1 and SGLT2 in human kidney and of SGLT1 in human small intestine, liver, lung, and heart.

Novel affinity-purified antibodies against human SGLT1 (hSGLT1) and SGLT2 (hSGLT2) were used to localize hSGLT2 in human kidney and hSGLT1 in human kidney, small intestine, liver, lung, and heart. The renal locations of both transporters largely resembled those in rats and mice; hSGLT2 and SGLT1 were localized to the brush border membrane (BBM) of proximal tubule S1/S2 and S3 segments, respectively. Different to rodents, the renal expression of hSGLT1 was absent in thick ascending limb of Henle (TALH) and macula densa, and the expression of both hSGLTs was sex-independent.

Histological groups of human postpubertal testicular germ cell tumours harbour different genetic alterations.

Background: Testicular germ cell tumours are the most common malignancies in young males. Molecular biology studies of these tumours are often contradictory. Two histological groups, seminoma and non-seminoma, differ both morphologically and in malignant behaviour.

Expression of Na+-D-glucose cotransporter SGLT2 in rodents is kidney-specific and exhibits sex and species differences.

With a novel antibody against the rat Na(+)-D-glucose cotransporter SGLT2 (rSGLT2-Ab), which does not cross-react with rSGLT1 or rSGLT3, the ∼75-kDa rSGLT2 protein was localized to the brush-border membrane (BBM) of the renal proximal tubule S1 and S2 segments (S1 > S2) with female-dominant expression in adult rats, whereas rSglt2 mRNA expression was similar in both sexes. Castration of adult males increased the abundance of rSGLT2 protein; this increase was further enhanced by estradiol and prevented by testosterone treatment. In the renal BBM vesicles, the rSGLT1-independent uptake of [(14)C]-α-methyl-D-glucopyranoside was similar in females and males, suggesting functional contribution of another Na(+)-D-glucose cotransporter to glucose reabsorption.

Loss of heterozygosity of CDKN2A (p16INK4a) and RB1 tumor suppressor genes in testicular germ cell tumors.

Background: Testicular germ cell tumors (TGCTs) are the most frequent malignances in young adult men. The two main histological forms, seminomas and nonseminomas, differ biologically and clinically. pRB protein and its immediate upstream regulator p16INK4a are involved in the RB pathway which is deregulated in most TGCTs.

Effect of 905 MHz microwave radiation on colony growth of the yeast Saccharomyces cerevisiae strains FF18733, FF1481 and D7.

Background: The aim of this study was to evaluate the effect of weak radiofrequency microwave (RF/MW) radiation emitted by mobile phones on colony growth of the yeast Saccharomyces cerevisiae.

Materials And Methods: S. cerevisiae strains FF18733 (wild-type), FF1481 (rad1 mutant) and D7 (commonly used to detect reciprocal and nonreciprocal mitotic recombinations) were exposed to a 905 MHz electromagnetic field that closely matched the Global System for Mobile Communication (GSM) pulse modulation signals for mobile phones at a specific absorption rate (SAR) of 0.

Loss of heterozygosity of selected tumor suppressor genes in human testicular germ cell tumors.

Human testicular germ cell tumors (TGCTs) are histologically heterogenous neoplasms with a variable malignant potential. Two main groups of germ cell tumors occur in men: seminomas and nonseminomas. In the present study, a set of four tumor suppressor genes was investigated in testicular cancers.
