Outpatient parenteral antimicrobial therapy (OPAT) programs are becoming an increasingly popular trend in clinical practice as they offer several benefits to both patients and health-care setups. While OPAT is an established clinical practice in the Western world, the concept itself is alien to patients in India as they prefer the security of hospitals to receive antibiotics over OPAT. We evaluated the clinical response and cost comparison of ertapenem under OPAT versus inpatient settings in patients with extended-spectrum beta-lactamase (ESBL)-positive acute pyelonephritis (APN) given the increasing importance of optimizing both hospital beds and overall cost of patient care in India...

Background: Unenhanced computed tomography (UCT) may be useful for evaluating acute pyelonephritis; however, no study has compared UCT with enhanced computed tomography (ECT) as a diagnostic tool. We evaluated a clinical usefulness of UCT versus ECT in acute pyelonephritis (APN). Methods: We reviewed the clinical and radiological data from 183 APN-suspected patients who underwent UCT and ECT simultaneously at emergency room (ER) over a two-year period. Demographic, clinical parameters and computed tomography (CT) parameters of 149 patients were compared...

Nonalcoholic fatty liver disease (NAFLD) is a common liver disease which has been previously shown to be associated with type 2 diabetes mellitus (T2DM). Recent research has indicated that type 1 diabetes mellitus (T1DM) is also involved in the development of nonalcoholic fatty liver disease, whereas the underlying mechanisms are largely unknown. Forkhead box O1 (FoxO1) and adiponectin (APN) have been proposed to play an important role in the processes in NAFLD in T1DM. We herein investigated the effects of FoxO1 and APN on the development of NAFLD and the underlying mechanism in streptozotocin-induced T1DM...

It is known that oral sodium phosphate, used as bowel preparation for colonoscopy, can cause acute phosphate nephropathy, a potentially severe and irreversible form of acute kidney injury. Due to these safety concerns, guidelines have advised against the routine use of this agent for a decade. We present a case report and biopsy series that demonstrate that oral sodium phosphate is still being used and that cases of APN are still occurring, in Australia.

BAKGRUNN: I 70 % av tilfellene med familiær amyotrofisk lateral sklerose (ALS) og 10 % av de med sporadisk form kan genetisk utredning gi en diagnose stilt på molekylært nivå. Molekylært stilt diagnose kan åpne for deltagelse i kliniske studier, men endrer ellers ikke behandlingen. Betydningen for slektningers sykdomsrisiko kan være usikker, og den psykologiske belastningen stor. Utredningen reiser vanskelige etiske spørsmål. Vi har undersøkt om klinisk praksis samsvarer med internasjonale anbefalinger, som fraråder genetisk utredning ved typisk sporadisk variant...

Neovascularization in retina and choroid involves interplay of many cytokines and growth factors. Vascular endothelial growth factor (VEGF) being a pro-angiogenic molecule has been found to be high in aqueous and vitreous humour of patients with proliferative diabetic retinopathy (PDR). VEGF is also found in the fibroblast and retinal pigment epithelial cells (RPE) of choroidal neovascular (CNV) membranes isolated from patients. Though anti-VEGF agents cause regression of clinically visible new vessels, there is evidence that they increase the occurrence of retinal tractional detachment and other adverse effects in PDR and CNV treatments...

Hydrogen bond (HB) mediated base pair motifs are versatile scaffolds of diverse supramolecular constructs. Here, we report that two novel four and six-membered supermacrocyclic assemblies with intriguing geometries can be self-assembled from two new adenine derivatives, APN (1) and APC (2). The conversion of a conventional HB acceptor, N8 of 1, to a non-conventional HB donor, C8-H of 2, has a pronounced impact on the whole intricate overall HB network and self-assembly patterns, epitomizing the subtleties in design and exploitation of such base pair motifs as promising tectons for building supramolecular architectures...

Adiponectin (APN) has been shown to play a key role in regulating bone mineral density (BMD). Nevertheless, the effects of APN on receptor activator of NF-κB ligand (RANKL)-induced osteoclast formation and mechanism of regulation are not entirely clear. The study, therefore, aimed to evaluate the effect of APN on osteoclastogenesis. Our results showed that APN inhibits osteoclastogenesis and resorption function in vitro by suppressing nuclear factor-κB (NF-κB) and p38 signaling pathways, which is essential for osteoclast formation...

Bacillus thuringiensis Cry1Ab and Cry1Fa toxins are environmentally safe insecticides that control important insect pests. Spodoptera frugiperda is an important maize pest that shows low susceptibility to Cry1A toxins, in contrast to Cry1Fa, which is highly active against this pest and is used in transgenic maize for S. frugiperda control. The β16 region from domain III of Cry1Ab has been shown to be involved in interactions with receptors such as alkaline phosphatase (ALP) or aminopeptidase (APN) in different lepidopteran insects...

Previous studies highlighted that aminopeptidase N (APN)/CD13 acts as a scavenger in the survival of hepatocellular carcinoma (HCC) stem cells by reducing reactive oxygen species (ROS) levels. Hence, it has been proposed that APN/CD13 inhibition can increase cellular ROS levels and sensitize cells to chemotherapeutic agents. Although ubenimex, also known as bestatin, competitively inhibits proteases such as APN/CD13 on the cellular membrane and it is clinically used for patients with acute myeloid leukemia and lymphedema, research has demonstrated that higher concentrations of the agent induce the death of APN/CD13+ HCC stem cells...

Laboratory cats were infected with a serotype I cat-passaged field strain of FIP virus (FIPV) and peritoneal cells harvested 2-3 weeks later at onset of lymphopenia, fever and serositis. Comparison peritoneal cells were collected from four healthy laboratory cats by peritoneal lavage and macrophages predominated in both populations. Differential mRNA expression analysis identified 5621 genes as deregulated in peritoneal cells from FIPV infected versus normal cats; 956 genes showed > 2.0 Log2 Fold Change (Log2 FC) and 1589 genes showed < -2...

This review focuses on recent advances in the molecular imaging of aminopeptidase N (APN, also known as CD13), a zinc metalloenzyme that cleaves N -terminal neutral amino acids. It is overexpressed in multiple cancer types and also on the surface of vasculature undergoing angiogenesis, making it a promising target for molecular imaging and targeted therapy. Molecular imaging probes for APN are divided into two large subgroups: reactive and nonreactive. The structures of the reactive probes (substrates) contain a reporter group that is cleaved and released by the APN enzyme...

The association between lower circulating adiponectin (APN) levels and the development of pancreatic cancer has been reported. However, the effect of APN on the growth and survival of pancreatic cancer cells remains elusive. Here, we investigate the effects of the anti-diabetic APN receptor (AdipoR) agonist AdipoRon and APN on human pancreatic cancer cells. We found that AdipoRon, but not APN, induces MIAPaCa-2 cell death, mainly through necroptosis. Mechanistically, although both AdipoRon and APN activate AMPK and p38 MAPK in an AdipoR-dependent manner that elicits survival signals, only AdipoRon induces rapid mitochondrial dysfunction through mitochondrial Ca2+ overload, followed by superoxide production via RIPK1 and ERK1/2 activation...

Newly graduated advanced practice nurses (APNs) often accept positions equipped only with brief, limited training and are expected to primarily learn on the job. APN fellowship programs, such as the oncology fellowship program at Sylvester Comprehensive Cancer Center (SCCC) in Florida, may be a solution to this problem; they provide in-depth training to APNs, offer support through open communication with preceptors, grant APNs opportunities to develop skills and confidence, and allow APNs the time to earn the trust of others at the institution and take on additional responsibilities...

The potent transcription inhibitor Actinomycin D is used with several cancers. Here, we report the discovery that this naturally occurring antibiotic inhibits two human neutral aminopeptidases, the cell-surface alanine aminopeptidase and intracellular methionine aminopeptidase type 2. These metallo-containing exopeptidases participate in tumor cell expansion and motility and are targets for anticancer therapies. We show that the peptide portions of Actinomycin D and Actinomycin X2 are not required for effective inhibition, but the loss of these regions changes the mechanism of interaction...
