REVIEW
Rishi Dhawan, David I Marks
Allogeneic haematopoietic cell transplantation continues to be an important curative therapy for acute lymphoblastic leukaemia (ALL). Traditionally accepted indications for allografting adult ALL patients need reevaluation in light of outcomes with paediatric-like intensive regimens. Minimal residual disease status and oncogenetics can be used for restratification of standard risk patients. A greater body of data on haematopoietic cell transplantation (HCT) outcomes from haploidentical and cord blood donor sources has been generated in recent years...

Pathophysiological processes following subarachnoid hemorrhage (SAH) present survivors of the initial bleeding with a high risk of morbidity and mortality during the course of the disease. As angiographic vasospasm is strongly associated with delayed cerebral ischemia (DCI) and clinical outcome, clinical trials in the last few decades focused on prevention of these angiographic spasms. Despite all efforts, no new pharmacological agents have shown to improve patient outcome. As such, it has become clear that our understanding of the pathophysiology of SAH is incomplete and we need to reevaluate our concepts on the complex pathophysiological process following SAH...

The aim of the study was to evaluate the exposure-response (E-R) relationships of blood pressure (BP) and heart rate (HR) changes in healthy adults taking methylphenidate (MPH). Intensive time profiles of BP and HR from healthy adults in placebo and MPH treatment arms of seven clinical trials from the FDA internal database were utilized for this analysis. The analysis model contains a circadian component for placebo effect and an E-R component to describe drug effect. Internal validation was performed using goodness-of-fit plots and visual predictive check...

The American Society of Anesthesiologist recommends peripheral physiological monitoring during general anesthesia, which offers no information regarding the effects of anesthetics on the brain. Since no "gold standard" method exists for this evaluation, such a technique is needed to ensure patient comfort, procedure quality and safety. In this study we investigated functional near infrared spectroscopy (fNIRS) as possible monitor of anesthetic effects on the prefrontal cortex. Anesthetic drugs, such as sevoflurane, suppress the cerebral metabolism and alter the cerebral blood flow...

BACKGROUND/AIM: Accumulation of advanced glycation end products (AGEs) is a major cause of diabetes mellitus (DM) skin complications. Methylglyoxal (MGO), a reactive dicarbonyl compound, is a crucial intermediate of AGEs generation. N-acetyl-L-cysteine (NAC), an active ingredient of some medicines, can induce endogenous GSH and hydrogen sulfide generation, and set off a condensation reaction with MGO. However, there is rare evidence to show NAC can alleviate DM-induced skin injury through inhibition of AGEs generation or toxicity...

The metastasis of cancer is strongly associated with the spread of circulating tumor cells (CTCs). Based on the microfluidic devices, which offer rapid recovery of CTCs, a number of studies have demonstrated the potential of CTCs as a diagnostic tool. However, not only the insufficient specificity and sensitivity derived from the rarity and heterogeneity of CTCs, but also the high-cost fabrication processes limit the use of CTC-based medical devices in commercial. Here, we present a low-cost fabric sheet layers for CTC isolation, which are composed of polyester monofilament yarns...

Huaifa Zhang, Jake E Barralet
In addition to immunological and wound healing cell and platelet delivery, ion stasis and nutrient supply, blood delivers oxygen to cells and tissues and removes metabolic wastes. For decades researchers have been trying to develop approaches that mimic these two immediately vital functions of blood. Oxygen is crucial for the long-term survival of tissues and cells in vertebrates. Hypoxia (oxygen deficiency) and even at times anoxia (absence of oxygen) can occur during organ preservation, organ and cell transplantation, wound healing, in tumors and engineering of tissues...

There is evidence to suggest athletes have adopted recombinant human erythropoietin (rHuEPO) dosing regimens that diminish the likelihood they will be caught by direct detection techniques. However, the temporal response in physiology, performance and athlete biological passport (ABP) parameters to such regimens is not clearly understood. Participants were assigned to a high dose only group (HIGH, n = 8, six rHuEPO doses of 250 IU/kg over two weeks), a combined high micro-dose group (COMB, n = 8, high dose plus nine rHuEPO micro-doses over a further three weeks), or one of two placebo control groups who received saline in the same pattern as the HIGH (HIGH-PLACEBO, n = 4) or COMB (COMB-PLACEBO, n = 4) groups...

INTRODUCTION: We investigated differences in metabolic stress (lactate) and muscle activation (electromyography) when high load exercise is compared to a condition where blood flow restriction (BFR) is applied during the exercise or during the rest interval. METHODS: Twelve participants performed high load resistance exercise with BFR during the intervals (BFR-I), during the set (BFR-S) and without BFR (HL). Each condition consisted of 3 sets of 8 repetitions with knee-extension at 70% of one-repetition-maximum...

AIM: Among the several organs affected by perinatal hypoxia, the heart plays a central role, with cell death caused mainly by apoptosis. One of the biomarkers most often linked to hypoxia-derived apoptosis of cardiomyocytes in animals is Gadd45β. From the published literature, Gadd45β is proposed as a biomarker of hypoxia-induced lesion in cardiomyocytes, both in vitro, as well as in animal models. Our study suggests that this protein can be used as an early biomarker of cell damage in neonate's cardiomyocytes (humans specimens), a process that can ultimately lead to apoptosis...

This study aims to determine whether successful laparoscopic fundoplication for gastroesophageal reflux disease (GERD) can improve the control of hypertension. We conducted an observational study of GERD patients with hypertension. The esophageal and gastroesophageal symptoms of these patients were successfully treated with laparoscopic fundoplication, as measured by the reduced GERD symptoms and proton pump inhibitor consumption. A hypertension control scale was used to classify the use of antihypertensive medications and the quality of blood pressure control before and after anti-reflux surgery...

Biofilm forming capacity of yeasts colonizing the intravenous devices is considered a key factor involved in the pathogenesis of Candida catheter-related bloodstream infections (CCRBSI). The biofilm production of strains of Candida spp. isolated both from the CVC and from the blood of patients with CCRBSI was compared to that of strains isolated from patients not having CCRBSI. Results, expressed in terms of Biofilm Index (BI), revealed that biofilm-producing strains were isolated in the CCRBSI group with a frequency significantly higher than in the non-CCRBSI group (χ(2) = 4...

BACKGROUND: CER-001 comprises recombinant human apolipoprotein A-I complexed with phospholipids that mimics natural, nascent, pre-β high-density lipoprotein (HDL). We present animal model data showing dose-dependent increases in cholesterol efflux with CER-001 and its subsequent elimination by reverse lipid transport, together with inhibition of atherosclerotic plaque progression. We report the first phase I study results with CER-001 in humans, starting at 0.25 mg/kg, which is 1/80th of the safe dose (20 mg/kg) established in 4-week multiple-dose animal studies dosed every second day...

REVIEW
Meis Moukayed, William B Grant
Global cancer incidence and mortality rates are high and increasing. Thus, it is imperative to find novel solutions to preventing cancer incidence and treating it at an affordable yet efficacious manner. The solar UVB-vitamin D-cancer hypothesis was first proposed in 1980 based on a geographical ecological study. Since then, numerous ecological and observational studies as well as studies of mechanisms have provided support for the hypothesis. However, observational studies have not provided consistent support, in part due to using a single blood draw from any season to use for serum 25-hydroxyvitamin D [25(OH)D] concentration in prospective studies with long follow-up times...

Adequate fluid therapy is highly important for the perioperative outcome of our patients. Both, hypovolemia and hypervolemia can lead to an increase in perioperative complications and can impair the outcome. Therefore, perioperative infusion therapy should be target-oriented. The main target is to maintain the patient's preoperative normovolemia by using a sophisticated, rational infusion strategy.Perioperative fluid losses should be discriminated from volume losses (surgical blood loss or interstitial volume losses containing protein)...
