In adults with non-promyelocytic acute myeloid leukemia (AML), high-dose cytarabine consolidation therapy has been shown to influence survival in selected patients, although the appropriate doses and schemes have not been defined. We evaluated survival after calculating the actual dose of cytarabine that patients received for consolidation therapy and divided them into 3 groups according to dose. We conducted a single-center, retrospective study involving 311 non-promyelocytic AML patients with a median age of 36 years (16-79 years) who received curative treatment between 1978 and 2007.

Study Design Retrospective chart review. Purpose This study compared the clinical and radiographic outcomes of patients treated with expandable and static interbody spacers following minimally invasive lateral lumbar interbody fusion (MIS-LLIF) with 12-month follow-up. Overview of Literature A common surgical option for the treatment of degenerative disk disease (DDD) is MIS-LLIF using static or expandable spacers to restore disk height (DH), neuroforaminal height (NH), and segmental lordosis. Static spacers may require excessive trialing and aggressive impaction, potentially leading to endpla

【Background and Objective】 Magnetizing the water prior to irrigation is a new technology developed over the past decades in China. The objective of this paper is to investigate how different irrigation water sources alter the effects of the magnetization on photosynthesis, physiological and biochemical characteristics, as well as the yield of lettuce. 【Method】 The experiment was conducted in a solar greenhouse with the Italian lettuce taken as the model plant. It consisted of non-magnetization (M0) and magnetization (M1); added to these are three irrigation water sources: fresh water (T1), rec

Endometriosis is a common, chronic, inflammatory disorder in women, characterized by the presence of endometrial tissue outside the uterus cavity. The disease affects ~10% of women during their reproductive age. There is some debates on the pathogenesis of endometriosis and its mechanism among the scientists; therefore, different hypotheses have been suggested. According to Sampson theory, a possible mechanism for seeding ectopic endometriotic lesions is a dysregulation of endometrial mesenchymal stem cells (eMSCs). In the present study, we evaluated the expression of candidate genes in eMSCs

Introduction: Proximal hypospadias repair has many postoperative complications such as urethrocutaneous fistulae, wound dehiscence, and urethral stricture. The beneficial effect of estrogen to promote wound healing has been known. We designed a study to determine whether preoperative stimulation of tissue with estrogen can reduce the postoperative complications associated with wound healing in patients undergoing hypospadias repair. Methods: Patients with proximal hypospadias requiring two-stage repairs (chordee correction followed by urethral tubularization) were randomized to estrogen and co

Betaine has been proposed as a low-cost source of methyl groups in poultry feed, replacing methionine and choline. The present study aimed to investigate the effect of betaine on growth performance, methionine metabolism, and methyl transfer in broilers aged 1 to 21 days fed a low-methionine diet. A total of 960 one-day-old male broilers were randomly divided into four groups: positive control (0.62% methionine in the diet), negative control (0.37% methionine in the diet), and two treatment groups (0.37% methionine in the diet plus either 1500 or 3000 mg betaine/kg diet).

The pathogen transmitting Aedes albopictus mosquito is spreading rapidly in Europe, putting millions of humans and animals at risk. This species is well-established in Albania since its first detection in 1979. The sterile insect technique (SIT) is increasingly gaining momentum worldwide as a component of area-wide-integrated pest management. However, estimating how the sterile males will perform in the field and the size of target populations is crucial for better decision-making, designing and elaborating appropriate SIT pilot trials, and subsequent large-scale release strategies.
