1. Frequency Reconfigurable Near-Zero Refractive Index Material for Antenna Gain Enhancement Applications
Abstract In this paper, a planar near-zero refractive index material (NZRIM) consisting of an outer loop with four symmetrical quarter-rings is proposed. The quarter-rings are connected to the outer loop by two symmetrical microstrip lines on the opposite side. The backside of the substrate has mutually central split microstrip lines. By loading adjustable c

2. Effects of Exercise Training on Left Ventricular Diastolic Function Markers in Patients with Obstructive Sleep Apnea: A Randomized Study
Abstract Background Exercise training (ET) is an adjunctive treatment for obstructive sleep apnea (OSA) and its consequences. However, the effects of exercise on heart remodeling are unknown in the population with OSA. Objective We investigated the effect of ET on markers of diastolic function, sleep parameters, and functional capacity in patients with O

4. Assessment of serum endocan levels in patients with beta-thalassemia minor
SUMMARY OBJECTIVE: Beta-thalassemia minor is a blood disease caused by a hereditary decrease in beta-globin synthesis, frequently leading to hypochromic microcytic anemia. Formerly called endothelial cell-specific molecule 1, endocan is a proteoglycan released by vascular endothelial cells in many organs. Our aim was to investigate the relationship between

5. Meta-Analysis of Pulmonary Artery Denervation for Treatment of Pulmonary Hypertension
ABSTRACT Introduction: Pulmonary artery denervation (PADN) can reduce the sympathetic nervous system (SNS) activity, reduce pulmonary artery pressure (PAP), and improve the quality of life in patients with pulmonary hypertension (PH). We conducted a systematic meta-analysis of the effectiveness of PADN in the treatment of PH patients. Methods: This is a co

6. Interactions between green manure and rock phosphate on corn production in family farms
ABSTRACT The aim of this study was to analyze whether the use of green manures in association with rock phosphate rates can guarantee corn yields to family farmers. An experiment was conducted with six types of green manures: Mucuna cinereum, Crotalaria juncea, Crotalaria ochroleuca, Cajanus cajan, Pennisetum glaucum and a weedy fallow control treatment; and

7. Does focal heterogeneity affect survival in postoperative ipsilateral multifocal and multicentric breast cancers?
SUMMARY OBJECTIVE: In multicentric/multifocal breast tumors, there may be immunological and histological differences between foci that may affect survival and treatment choice. We aimed to evaluate the effect of focal heterogeneity seen in multicentric/multifocal breast tumors on survival. METHODS: We retrospectively collected and analyzed the clinicopatho

8. Vaginal Distention Rodent Model for Fecal Incontinence: A Pilot Study on the Effect on Defecation Behavior
Abstract Objectives Vaginal balloon inflation simulates the compressive forces on the pelvic floor during the second phase of natural delivery. The foremost use of this animal model of vaginal distention (VD) is to study the mechanisms underlying urinary incontinence. As damage to the pelvic floor during natural birth is a common cause of fecal incontinence

12. Effects of consumption of a low glycaemic index formula on glycaemic control in patients with type 2 diabetes managed by medical nutrition therapy
Abstract To evaluate the effect of medical nutritional therapy (MNT) combined with low glycaemic index (LGI) formula at breakfast for 4 weeks on the glycaemic control of patients with type 2 diabetes mellitus (T2DM). Ninety-six participants were recruited and randomly equally divided into two groups. The intervention group was offered with 40g LGI formula at
