A prototype system for the removal of Cs from liquid radioactive waste using reverse osmosis membrane.

Cesium removal from aqueous solutions of radioactive waste streams is a challenge in the field of radioactive waste management; this is due to the small atomic radii of Cs metal ions and their high migration ability. So, the development of a withstand system for the removal of Cs is crucial. In the current study, the removal of radioactive cesium from aqueous solutions using an RO-TLC membrane was studied.

Three-Dimensional Evaluation of Skeletal Stability following Surgery-First Orthognathic Approach: Validation of a Simple and Effective Method.

 The three-dimensional (3D) evaluation of skeletal stability after orthognathic surgery is a time-consuming and complex procedure. The complexity increases further when evaluating the surgery-first orthognathic approach (SFOA). Herein, we propose and validate a simple time-saving method of 3D analysis using a single software, demonstrating high accuracy and repeatability.

Are We Correctly Measuring Mandibular Stability After Surgery-First Approach? A Comparative Study Based on Novel 3-Dimensional Measurements.

Using traditional measures to assess mandibular stability after the surgery-first approach (SFA) may produce inaccurate results because unlike the conventional orthodontic-first approach (OFA), the main dental movements occur after surgery in SFA, which produce unavoidable mandibular movements, especially in cases with postsurgical premature dental contact. As these movements are part of the surgical-orthodontic plan, they should not be considered an actual relapse. In this study, to avoid postsurgical dental movement effects, the authors used the relationship between proximal and distal mandibular segments to evaluate stability after SFA.

Leukemia Inhibitory Factor a Marker of Implantation Success in Unexplained Infertility: a Randomized Controlled Trial.

Background: Uterine receptivity and implantation are complex processes requiring coordinated expression of molecules by zygote and uterus. Leukemia inhibitory factor (LIF) is one of the most important cytokines in the reproductive tract. Without expression of LIF in the uterus, implantation of a blastocyst cannot begin.

Outcome comparison between thoracodorsal artery perforator flap and muscle-sparing latissimus dorsi flap in axillary reconstruction after hidradenitis suppurativa excision.

Background: Thoracodorsal artery perforator (TDAP) flap and muscle-sparing latissimus dorsi (MSLD) flap have been frequently used for axillary coverage after hidradenitis suppurativa (HS) excision. However, none showed superiority to others. This study compared both flaps to define the ideal option, highlighting flap outcomes and functional and aesthetic results.

Heat recovery steam generator (HRSG) three-element drum level control utilizing Fractional order PID and fuzzy controllers.

Shrink and swell is a phenomenon that causes transient variability in water level once boiler load variation occurs. The leading cause of the swell effect is the steam demand changes and the actual arrangement of steam generating tubes in the boiler. Steam bubbles beneath HRSG drum water make the level control very difficult, particularly with significant disturbances in the input heat to HRSG.

Nano-sized Prussian blue immobilized costless agro-industrial waste for the removal of cesium-137 ions.

For human health and safety, it is of great importance to develop innovative materials with a vast capacity for powerful removal of radioactive ions from aqueous solutions. Prussian blue functionalized sugarcane bagasse (PB-SCB) was successfully prepared for the efficient elimination of radioactive cesium (Cs) using a nontoxic, environmentally friendly, and costless method. The prepared renewable material was characterized using different techniques to emphasize morphology, functional groups, crystal structure, and the adsorption process.

Effects of microbial feed additives on feed utilization and growth performance in growing Barki lambs fed diet based on peanut hay.

The effects of supplementing diet of growing lambs with microbial feed additive mixture (direct-fed microbial; DFM) based on , lactic acid bacteria and exogenous enzymes on feed intake, nutrient digestibility, nitrogen (N) utilization, ruminal fermentation, blood chemistry and growth performance were studied. The study was a completely randomized design with 12 growing Barki lambs divided into two groups of six lambs per treatment. Lambs were offered a control diet of peanut hay and concentrates (1:1 dry matter (DM) basis) or the control diet supplemented with DFM at 0.

The authors wish to acknowledge that whilst this study and that published in Hammad et al [1] explore different areas - blood cell ratios and serum endocan, respectively - the reader may identify some similarities between the papers owing to the same patient cohort being analysed in both studies.

Effect of chlormadinone acetate versus drospirenone-containing oral contraceptives on the endocrinal features of women with polycystic ovary syndrome: Systematic review and meta-analysis of randomized clinical trials.

Background: Polycystic ovary syndrome (PCOS) is a serious endocrinal disorder in women of reproductive age. Hormonal treatment with oral contraceptives, containing estrogen (ethinyl-estradiol, EE) with progestogen (drospirenone, DRSP) or (chlormadinone acetate, CMA), has improved symptoms and biomarkers of PCOS.

Prepubertal IGF-1 and Possible Relation with Physical Features of Growth and Type 1 Diabetes Mellitus.

Background: T1DM is considered as the most common chronic metabolic autoimmune disorder in childhood and adolescence as well as in the early adulthood. It appears frequently during 12- 13 years of age with distinctive features like immune-mediated chronic damage of pancreatic β-cells, leading eventually to partial, or mostly, absolute insulin deficiency. Insulin-like growth factor 1 (IGF-1) is a polypeptide consisting of 70 amino acids with insulin-like chemical structure.

New polymorphism in the 5' flanking region of gene and its association with wool traits in Egyptian Barki sheep.

Insulin-like growth factor-1 gene () is considered as a major candidate gene for the economic traits of animal production. Polymorphism of 5' flanking region of gene in Barki sheep (n = 91) and its association with wool traits were studied using the polymerase chain reaction coupled with single-strand conformation polymorphism technique (PCR-SSCP), PCR-restriction fragment length polymorphism (PCR-RFLP), sequence analysis and different measurements of wool traits (clean fleece weight and fiber diameter). PCR-SSCP analysis revealed three different banding patterns corresponding with three genotypes frequencies GG (0.

Neutrophil/lymphocyte ratio and platelet/lymphocyte ratio in Behçet's disease: which and when to use?

Behçet's disease (BD) is an uncommon autoimmune/autoinflammatory disease. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were investigated in many diseases as a marker of inflammation.
