Prevalence of Gastrointestinal Symptoms and Clinical Outcomes in Hospitalized Coronavirus Disease 2019 Patients: A Single-Center Study from Turkey.

Background: In patients with coronavirus disease 2019, the gastrointestinal symptoms have been reported increasingly in addition to the respiratory system symptoms. The studies show that the prevalence of gastrointestinal system symptoms and how the gastrointestinal system contributes to the severity and prognosis of the disease is still not clear. This study aims to find the prevalence of gastrointestinal symptoms and the correlation between the gastrointestinal symptoms and the clinical results in hospitalized patients diagnosed with coronavirus disease 2019.

Effect of Blood Cell Subtypes Lysis on Routine Biochemical Tests.

Background: The aim of this study is to establish the contribution of blood cells subtypes on hemolysis.

Methods: Separated blood cell subtype suspensions prepared with blood from 10 volunteers were serially diluted to obtain different concentrations of cell suspensions. The cells were fully lysed and cell hemolysates were added (1:20) to aliquots of serum pool.

Do mothers with high sodium levels in their breast milk have high depression and anxiety scores?

Objective This study aimed to assess the possible association of high breast milk sodium levels with postpartum depression and anxiety. Methods A total of 150 mothers and their healthy, exclusively breastfed newborns aged 8 to 15 days were recruited. Mothers were asked to complete scales for evaluation of postnatal depression and anxiety following an interview for consent and sociodemographic data collection.

The effects of resistance training on cardiovascular disease risk factors in postmenopausal women: a randomized-controlled trial.

Our aim was to determine the effects of resistance training on cardiovascular risk factors in postmenopausal women. Forty-five women were included in the study. Resistance exercises were done with an intensity of 60% of 1-Repetition Maximum, for 12 weeks.

Pregnenolone protects the PC-12 cell line against amyloid beta peptide toxicity but its sulfate ester does not.

Pregnenolone (P), the main precursor of the steroids, and its sulfate ester, pregnenolone sulfate (PS), are the major neurosteroids produced in the neural tissue. Many neuroendocrinological studies stressed the neuroprotective role of neurosteroids although it has been suggested that the inhibition of P and PS synthesis can delay neuronal cell death. The potential roles of P and PS in vital neuronal functions and in amyloid beta peptide (Abeta) toxicity are not clearly identified.

The protective effects of carnosine and melatonin in ischemia-reperfusion injury in the rat liver.

The reperfusion following liver ischemia results in hepatocyte damage and apoptosis. The aim of this study was to investigate the effects of two antioxidant agents, carnosine and melatonin, in rat liver ischemia-reperfusion injury. Five study groups were formed; I.

The effects of irbesartan and spironolactone in prevention of peritoneal fibrosis in rats.

Background: Bacterial peritonitis episodes may disturb the functional and histological integrity of the peritoneum in peritoneal dialysis patients. The renin-angiotensin-aldosterone system may have fibrotic effects on the peritoneum.

Objective: To study the effects of an angiotensin II receptor antagonist (irbesartan) and an aldosterone antagonist (spironolactone) in the prevention of peritoneal fibrosis in a rat model of bacterial peritonitis.

The inappropriate use of HbA1c testing to monitor glycemia: is there evidence in laboratory data?

Rationale, Aims And Objectives: Diabetes is a chronic illness and have relatively high prevalence. Glycemic control is fundamental to the management of diabetes. Hemoglobin A1c (HbA1c) is a commonly used laboratory test to monitor glycemia and to manage diabetes.

Nitric oxide levels in disruptive behavioral disorder.

There are various evidences of the role of nitric oxide (NO) in several neuropsychiatric disorders. However, there is no clinical study which investigated the role of NO in disruptive behavioral disorders (DBD). The aim of this study is to investigate the relation between NO levels and DBD.

Effects of N-acetylcysteine on radiocontrast nephropathy in rats.

Objective: N-acetylcysteine (NAC) has yielded some promising results recently in the prevention of radiocontrast nephropathy (RCN). In this study, the structural and functional effects of NAC on RCN were analyzed.

Material And Methods: Twenty-eight Wistar rats were randomized into four groups, as follows: Group 1, controls; Group 2, contrast; Group 3, contrast+NAC; and Group 4, NAC.

Alanine aminotransferase deficiency in a hepatitis B surface antigen positive patient presenting with acute hepatitis.

This report presents a hepatitis B surface antigen positive case presenting with acute hepatitis and with findings of low serum alanine aminotransferase in contrast to very high levels of aspartate aminotransferase. A 64 year-old female patient was admitted to our hospital with fatigue and jaundice. Hepatitis B surface antigen was positive.

Diagnostic usefulness of carbohydrate antigen-125 in cancerous and noncancerous peritoneal effusions.

Carbohydrate antigen-125 (CA-125) is a tumor marker that has been used for differential diagnosis of peritoneal malignancies. The aim of the present study was to evaluate the diagnostic usefulness of simultaneous quantification of CA-125 in peritoneal fluid and serum for abdominal cancer cases and noncancer diseases. Noncancer disease group included cirrhotic patients (n=28) and spontaneous bacterial peritonitis (SBP) patients (n=11).

[The beneficial effect of L-carnitine in rat renal ischemia-reperfusion injury].

Background: We examined the effect of L-carnitine on experimental renal ischemia-reperfusion (I-R) injury.

Methods: Seventy-two Wistar albino rats were divided into five groups, four of which underwent right nephrectomy and left renal I-R for 60 min (groups 2 and 4) and 90 min (groups 3 and 5). The sham operated group (n=8) was left as controls.
