In this work four stable bio-waste composts (C1, C2, C3, C4) were selected on the basis of their increasing water soluble P (H2O-P). The P speciation was assessed via sequential chemical extraction (SCE) on the same products. Moreover, the plant-available P was assessed via apparent recovery fraction approach (ARF) in a pot test on ryegrass over 21 weeks at 15 mg P kg(-)(1) of soil. An inorganic P source (P-chem) was added as a reference at the same P rate in addition to a non-fertilized control (Control)...

BACKGROUND: Hydrogen peroxide (H2O2) has been known to function as a signalling molecule involved in the modulation of various physiological processes in plants. H2O2 has been shown to act as a promoter during adventitious root formation in hypocotyl cuttings. In this study, RNA-Seq was performed to reveal the molecular mechanisms underlying H2O2-induced adventitious rooting. RESULTS: RNA-Seq data revealed that H2O2 treatment greatly increased the numbers of clean reads and expressed genes and abundance of gene expression relative to the water treatment...

BACKGROUND: Inborn errors of cobalamin (Cbl) metabolism form a large group of rare diseases. One of these, Cbl deficiency type C (CblC), is a well-known cause of thrombotic microangiopathy (TMA), especially in infants. However, there has only been a single published case of TMA associated to Cbl deficiency type G (CblG), also known as methionine synthase deficiency (MSD). CASE DIAGNOSIS/TREATMENT: A 21-month-old boy presented with pallor and oral ulcers during episodes of upper respiratory infection (URI)...

We theoretically and experimentally characterize a liquid-filled nodeless anti-resonant fiber (LARF) that could find versatile applications in biochemical sensing. When a hollow-core nodeless anti-resonant fiber (HARF) is filled with a low refractive index liquid such as water or aqueous solutions in the whole hollow area, it preserves its anti-resonant reflection waveguiding mechanism with attributes encompassing the broad transmission bandwidth in UV, visible, and near IR; the neglectable confinement loss; and the acceptable single-mode quality...

Attachment of active, GTP-bound small GTPases to membranes by post-translational lipid modifications is pivotal for their ability to process and propagate information in cells. However, generating and manipulating lipidated GTPases has remained difficult, which has limited our quantitative understanding of their activation by GEFs and their termination by GAPs. Here we replaced the lipid modification by a histidine tag in eleven full-length, human small GTPases belonging to the Arf, Rho and Rab families, which allowed to tether them to nickel-lipid containing membranes and characterize the kinetics of their activation by GEFs...

Virulence of the human fungal pathogen Candida albicans depends on the switch from budding to filamentous growth, which requires sustained membrane traffic and polarized growth. In many organisms, small GTPases of the Arf (ADP-ribosylation factor) family regulate membrane/protein trafficking, yet little is known about their role in fungal filamentous growth. To investigate these GTPases in C. albicans, we generated loss of function mutants in all 3 Arf proteins, Arf1-Arf3, and 2 Arf-like proteins, Arl1 and Arl3...

A 10-year-old girl presented with acute renal failure (ARF) with a serum creatinine of 7.5 mg/dL. Imaging showed bilateral hydroureteronephrosis and a large bladder stone (75×55 mm). The large bladder stone was probably the aetiology of bilateral hydronephroureter and ARF as no other cause could be found. An open cystolithotomy was performed. Ten days after the surgery, serum creatinine decreased to 0.7 mg/dL. In this report, we highlight an unusual cause of renal failure.

BACKGROUND: Although breast cancer is most prevalent among older women, the majority are diagnosed at an early stage. When diagnosed at an early stage, women have the option of breast-conserving surgery (BCS) plus radiation therapy (RT) or mastectomy for the treatment of early-stage breast cancer (ESBC). Omission of RT when receiving BCS increases the risk for recurrence and poor survival. Yet, a small subset of older women may omit RT after BCS. This study examines the current patterns of local treatment for ESBC among older women...

REVIEW
Scott Dougherty, Maziar Khorsandi, Philip Herbst
Rheumatic heart disease (RHD) is a disease of poverty, is almost entirely preventable, and is the most common cardiovascular disease worldwide in those under 25 years. RHD is caused by acute rheumatic fever (ARF) which typically results in cumulative valvular lesions that may present clinically after a number of years of subclinical disease. Therapeutic interventions, therefore, typically focus on preventing subsequent ARF episodes (with penicillin prophylaxis). However, not all patients with ARF develop symptoms and not all symptomatic cases present to a physician or are correctly diagnosed...

Besides association with acute rheumatic fever (ARF) and acute glomerulonephritis (APSGN), in up to 40% of cases, Group A β-haemolytic streptococcal (GABHS) infections are also implicated as a trigger for Henoch-Schonlein purpura (HSP). A 7-year-old girl with GABHS throat infection who developed HSP, APSGN and rheumatic carditis is reported. She presented with palpable purpura and arthritis in both ankles and later developed carditis characterised by mitral/aortic regurgitation and glomerulonephritis characterised by mixed nephritic/nephrotic syndrome...

We report a case of morning glory syndrome (MGS) associated with persistent hyperplastic primary vitreous (PHPV) and Peters' anomaly. A 2-day-old girl, born at term with a birth weight of 3,350 g was diagnosed with Peters' anomaly, cataract, microphthalmia, PHPV, and MGS. A right limbal lensectomy and vitrectomy with stalk cauterization was performed 8 days later. No early postoperative complication occurred, the family was discharged with advice on medication, and follow-up examination was scheduled. The case report reveals the coexistence of PHPV, Peters' anomaly, and MGS, which may suggest a genetic link...

Multiple myeloma (MM) is a hematologic malignancy characterized by clonal proliferation of plasma cells and overproduction of monoclonal immunoglobins. Treatment with melphalan is currently standard of care for younger and fit patients when followed by hematopoietic stem cell transplantation (HSCT), and in transplant ineligible patients when used in combination regimens. It has been previously shown that changes in the p53 pathway are associated with melphalan efficacy, but the regulatory role of the p14ARF-MDM2-p53 axis has yet to be fully explored...

Recent research identifies that certain training load (TL) patterns increase the injury risk to athletes. However, physical fitness must also be considered to establish optimal TL patterns. The aim of this study was to identify TL patterns optimal for injury and aerobic fitness by exploring the TL-injury and TL-fitness relationship concurrently over an Australian rules football (ARF) preseason. Individual TL, aerobic fitness and injury data were collected over a 14-week preseason in sixty sub-elite ARF players (age = 21...

Herein we report our studies, initially on C-F bond activation by cAAC-stabilized nickel(0) complex [Ni(cAACmethyl)2] (2), which then led to observation of C-F bond cleavage of perfluorinatied arenes by the carbene ligand cAACmethyl (1) itself. We were able to investigate further transformations of the obtained activation products (cAACmethyl)F(Arf) 4a-d in fluoride abstraction or fluorine transfer reactions. To get an insight into the chemoselectivity of these reactions, we treated carbine 1 with partially fluorinated arenes, which led to the observation of C-H bond activation...

Wnt signaling, named after the secreted proteins that bind to cell surface receptors to activate the pathway, plays critical roles both in embryonic development and the maintenance of homeostasis in many adult tissues. Two particularly important cellular programs orchestrated by Wnt signaling are proliferation and stem cell self-renewal. Constitutive activation of the Wnt pathway resulting from mutation or improper modulation of pathway components contributes to cancer development in various tissues. Colon cancers frequently bear inactivating mutations of the adenomatous polyposis coli (APC) gene, whose product is an important component of the destruction complex that regulates β-catenin levels...
