D A Gardner-Dale, I M Bradley, J S Guest
Microalgal treatment systems could advance nutrient recovery from wastewater by achieving effluent nitrogen (N) and phosphorus (P) levels below the current limit of technology, but their successful implementation requires an understanding of how design decisions influence nutrient uptake over daily (i.e., diel) cycles. This work demonstrates the ability to influence microalgal N:P recovery ratio via solids residence time (SRT) while maintaining complete nutrient removal across day/night cycles through carbon storage and mobilization...

The double-membrane-bound autophagosome is formed by the closure of a structure called the phagophore, origin of which is still unclear. The endoplasmic reticulum (ER) is clearly implicated in autophagosome biogenesis due to the presence of the omegasome subdomain positive for DFCP1, a phosphatidyl-inositol-3-phosphate (PI3P) binding protein. Contribution of other membrane sources, like the plasma membrane (PM), is still difficult to integrate in a global picture. Here we show that ER-plasma membrane contact sites are mobilized for autophagosome biogenesis, by direct implication of the tethering extended synaptotagmins (E-Syts) proteins...

Gout is one of the most painful types of arthritis that arises when the body mounts an acute inflammatory reaction against a crystallized form of uric acid known as monosodium urate crystals (MSUs). Although MSUs are known to activate neutrophils, the most abundant leukocyte in the synovial fluid of patients with gout, few studies have investigated the effect on neutrophils of the simultaneous stimulation with MSU and proinflammatory mediators in the inflamed joint. Herein, we focused on a protein that is highly expressed in the synovium in gout, S100A9...

OBJECTIVES: The optimum treatment with intramedullary nails (IMN) or sliding hip screws (SHS) for type 31-A2 trochanteric fractures remains controversial. Therefore, we performed a meta-analysis of randomized controlled trials (RCTs) to compare IMN with SHS in AO/OTA 31-A2 trochanteric fractures. MATERIAL AND METHODS: Databases including PubMed, Cochrane, and Embase were searched to identify RCTs published before December 2016, which compared IMN with SHS for intraoperative and postoperative outcomes in AO/OTA 31-A2 trochanteric fractures...

AIMS: Voltage-gated potassium channels 1.3 (Kv1.3) can be targeted to reduce diet-induced obesity and insulin resistance in mice. Since species-specific differences in Kv1.3 expression and pharmacology have been observed, we tested the effect of Vm24, a high-affinity specific blocker of Kv1.3 channels from Vaejovis mexicanus smithi, on body weight (BW), glucose tolerance and insulin resistance in diet-induced obese rats. MATERIALS AND METHODS: Young adult male Wistar rats were switched to a high-fat/high-fructose (HFF) diet...

Adipose triglyceride lipase (ATGL) is a rate-limiting enzyme that mobilizes fatty acids from cellular triglyceride stores. Metabolic syndrome, which refers to a group of abnormalities that occur together and increase the risk of coronary artery disease, stroke, type-2 diabetes, and cachexia, can be treated using ATGL-specific inhibitors. Atglistatin (1) is the first small-molecule inhibitor of ATGL. In this study, we designed and synthesized 29 Atglistatin derivatives and evaluated their inhibition of forskolin-stimulated lipolysis in 3T3-L1 adipocytes as an indicator of their potential to inhibit ATGL in adipose tissues...

We treated a 64-year-old man for rectal cancer with direct invasion to the seminal vesicles and no distant metastases by complete resection with laparoscopy and transanal minimally invasive surgery (TAMIS). We inserted the TAMIS device into the anal canal to above the anorectal ring and dissected to prostate level. High ligation of the inferior mesenteric artery and vein was performed by standard medial laparoscopy. The sigmoid and descending colon were mobilized, and in the postrectal space, we dissected to the space made by TAMIS...

Retrorectal tumors (RT) are uncommon and usually managed by open surgical excision. Laparoscopic excision for RT has been reported in only a small number of papers. We aimed to assess the laparoscopic approach for RT and to discuss the factors that made this procedure difficult. We performed laparoscopic excision using a five-trocar technique for neurogenic RT in three patients. Tumors were successfully excised laparoscopically in two patients. However, the third patient required open conversion because the tumor was strongly adhered to the sacrum and could not be mobilized by dissection, resulting in poor visualization of the dissected site...

Children with progressive neuromuscular weakness undergo a stereotypical progression of respiratory involvement, beginning with impaired airway clearance and progressing to nocturnal and then diurnal ventilatory failure. This review examines issues related to airway clearance and mucus mobilization, sleep problems, and use of assisted ventilation in children with neuromuscular diseases. Interventions for each of these problems have been created or adapted for the pediatric population. The use of airway clearance therapies and assisted ventilation have improved survival of children with neuromuscular weakness...

Inadequate pain management after total knee arthroplasty (TKA) impedes recovery, increases the risk of postoperative complications, and results in patient dissatisfaction. Although the preemptive use of multimodal measures is currently considered the principle of pain management after TKA, no gold standard pain management protocol has been established. Peripheral nerve blocks have been used as part of a contemporary multimodal approach to pain control after TKA. Femoral nerve block (FNB) has excellent postoperative analgesia and is now a commonly used analgesic modality for TKA pain control...

Early amniotic vertebrates evolved large-yolked eggs that permitted production of well-developed, terrestrial hatchlings. This reproductive pattern required new mechanisms for cellularizing the yolk and mobilizing it for embryonic use. In birds, cells that line the yolk sac cavity phagocytose and digest the yolk material, a pattern that is commonly assumed to be universal among oviparous amniotes. However, recent evidence challenges the assumption that all squamate reptiles conform to the avian developmental pattern...

Achieving an adequate blood supply in Sub-Saharan Africa (SSA) through donor mobilization and retention is crucial. Factors that motivate or deter blood donors vary according to beliefs and social norms. Understanding the factors that influence blood donation behaviour in SSA is vital to developing effective strategies to address blood donor motivation and retention. This review of 35 studies from 16 SSA countries collates available evidence concerning the perceptions, motivators and deterrents that influence blood donors in SSA...

Relapse is the main cause of treatment failure after allogeneic haematopoietic stem cell transplantation (allo-HSCT) for acute leukaemia (AL). Post-transplantation minimal residual disease (MRD) monitoring enables risk stratification and identifies AL patients at higher risk of relapse. MRD assessment primarily involves the determination of leukaemia-associated immunophenotypic patterns using multiparameter flow cytometry, and the polymerase chain reaction (PCR)-based evaluation of expression levels of leukaemia-related genes (specific reciprocal gene rearrangements and other mutation types)...

The repair of lower leg defects, not amenable to primary closure, may be challenging, since the skin at this level is scarcely elastic and difficult to mobilize. Local skin flaps are generally utilized only to restore moderately sized losses, whereas grafting becomes a realistic choice in presence of larger wounds. We present the case of a 70-year-old man with a wide defect on his right leg following the surgical excision of a squamous cell carcinoma. The wound was successfully closed with a combination of three hatchet flaps...

Objective: Autologous stem cell transplantation is an important strategy for patients with relapsed or refractory lymphoma. Although various regimens for peripheral blood stem cell collection have been used, the optimal regimen has not yet been established. We aimed to evaluate the mobilization efficacy and safety of the regimen consisted of etoposide and cytarabine (EC regimen). Methods: We retrospectively analyzed the clinical data of 46 lymphoma patients who received peripheral blood stem cell mobilization with the EC regimen [etoposide (100 mg/m2/day, days 1-4) and cytarabine (100 mg/m2/day, days 1-4)] at Toyohashi municipal hospital from 2004 to 2013...

OBJECTIVES: Femoral cutdown is standard in most centres if groin cannulation is used for cardiopulmonary bypass in minimally invasive cardiac surgery (MICS). Arterial closure devices (ACDs) allow placement of larger cannulas percutaneously, but its benefit in MICS is unclear. We assessed our results with percutaneous groin cannulation using ACDs in comparison with conventional surgical access in patients undergoing MICS. METHODS: We reviewed 445 consecutive patients having undergone MICS between October 2010 and March 2015...

Cyclooxygenase-2 catalyses the biosynthesis of prostaglandins from arachidonic acid but also the biosynthesis of prostaglandin glycerol esters (PG-Gs) from 2-arachidonoylglycerol. Previous studies identified PG-Gs as signalling molecules involved in inflammation. Thus, the glyceryl ester of prostaglandin E2, PGE2-G, mobilizes Ca(2+) and activates protein kinase C and ERK, suggesting the involvement of a G protein-coupled receptor (GPCR). To identify the endogenous receptor for PGE2-G, we performed a subtractive screening approach where mRNA from PGE2-G response-positive and -negative cell lines was subjected to transcriptome-wide RNA sequencing analysis...

Nicotinic acid adenine dinucleotide phosphate (NAADP) and cyclic ADP-ribose (cADPR) are Ca(2+)-mobilizing messengers important for modulating cardiac excitation-contraction coupling and pathophysiology. CD38, which belongs to the ADP-ribosyl cyclase (ARC) family, catalyzes synthesis of both NAADP and cADPR in vitro However, it remains unclear whether this is the main enzyme for their production under physiological conditions. Here, we show that membrane fractions from WT but not CD38(-/-) mouse hearts supported NAADP and cADPR synthesis...
