Pauci-immune focal necrotizing GN (piFNGN) is usually associated with ANCAs that are thought to be pathogenic. However, 10%-15% of patients are ANCA negative and the cause of their injury is unknown. We previously reported a high frequency of autoantibodies to human lysosome-associated membrane protein-2 (hLAMP-2) in ANCA-associated piFNGN, and have now investigated whether the same is true in ANCA-negative patients.

Macrophages respond to their microenvironment and develop polarized functions critical for orchestrating appropriate inflammatory responses. Classical (M1) activation eliminates pathogens while alternative (M2) activation promotes regulation and repair. M1 macrophage activation is strongly associated with suppressor of cytokine signalling 3 (SOCS3) expression in vitro, but the functional consequences of this are unclear and the role of SOCS3 in M1-macrophage polarization in vivo remains controversial.

The kidneys are frequently targeted by pathogenic immune responses against renal autoantigens or by local manifestations of systemic autoimmunity. Recent studies in rodent models and humans have uncovered several underlying mechanisms that can be used to explain the previously enigmatic immunopathology of many kidney diseases. These mechanisms include kidney-specific damage-associated molecular patterns that cause sterile inflammation, the crosstalk between renal dendritic cells and T cells, the development of kidney-targeting autoantibodies and molecular mimicry with microbial pathogens.

Article Synopsis
  • The study investigates factors affecting childhood hearing loss using historical data from the Newcastle Thousand Families Study, focusing on a cohort born in 1947.
  • Findings revealed that ear infections in early life are linked to poorer hearing thresholds, especially at lower frequencies, with specific impacts noted for females compared to males.
  • Contrary to expectations, early growth and socio-economic status showed no significant relationship with hearing levels, emphasizing the importance of addressing childhood infections in public health strategies.

A differential response to sound frequency is a fundamental property of auditory neurons. Frequency analysis in the cochlea gives rise to V-shaped tuning functions in auditory nerve fibres, but by the level of the inferior colliculus (IC), the midbrain nucleus of the auditory pathway, neuronal receptive fields display diverse shapes that reflect the interplay of excitation and inhibition. The origin and nature of these frequency receptive field types is still open to question.

This study explored sex differences in 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) activity and gene expression in isolated adipocytes and adipose tissue (AT), obtained via subcutaneous biopsies from non-diabetic subjects [58 M, 64 F; age 48.3 ± 15.3 years, body mass index (BMI) 27.

We describe a patient with Noonan syndrome (NS) presenting with ulerythema ophrygenes (UO)--an association initially suggested in a single case series of five patients by Pierini and Pierini in 1979. Recognition of the association of UO with NS by pediatric dermatologists is important because of the high incidence of cardiovascular anomalies in NS. Therefore, in infants and children presenting with UO, clinicians should maintain a high index of suspicion for NS and refer for further workup.

Background: The evidence base which supported the National Institute for Health and Clinical Excellence (NICE) published Clinical Guideline 3 was limited and 50% was graded as amber. However, the use of tests as part of pre-operative work-up remains a low-cost but high-volume activity within the NHS, with substantial resource implications. The objective of this study was to identify, evaluate and synthesise the published evidence on the clinical effectiveness and cost-effectiveness of the routine use of three tests, full blood counts (FBCs), urea and electrolytes tests (U&Es) and pulmonary function tests, in the pre-operative work-up of otherwise healthy patients undergoing minor or intermediate surgery in the NHS.

The auditory pathways coursing through the brainstem are organized bilaterally in mirror image about the midline and at several levels the two sides are interconnected. One of the most prominent points of interconnection is the commissure of the inferior colliculus (CoIC). Anatomical studies have revealed that these fibers make reciprocal connections which follow the tonotopic organization of the inferior colliculus (IC), and that the commissure contains both excitatory and, albeit fewer, inhibitory fibers.

Purpose Of Review: This review critically analyses the data implicating antibodies to lysosome associated membrane protein-2 (hLAMP-2) in ANCA-associated vasculitis (AAV). It addresses recent controversies over prevalence of anti-hLAMP-2 antibodies as well as their potential for diagnosis and monitoring disease activity.

Recent Findings: Anti-hLAMP-2 antibodies were first described in the 1990s and have become the focus of intense clinical interest in the past 4 years.

The oceans are under pressure from human activities. Following 250 years of industrial activity, effects are being seen at the cellular through to regional and global scales. The change in atmospheric CO(2) from 280 ppm in pre-industrial times to 392 ppm in 2011 has contributed to the warming of the upper 700 m of the ocean by approximately 0.

Introduction: Certain types of smokeless tobacco (ST) are popular among some people of South Asian origin in England; however, little is known about the contextual factors surrounding use in this population. This systematic review explores the factors associated with ST use among people of South Asian origin in England.

Methods: An iterative search strategy in targeted databases and grey literature sources was conducted in the summer of 2011.

Inhibition of 11β-HSD1 is viewed as a potential target for the treatment of obesity and other elements of the metabolic syndrome. We report here the optimization of a carboxylic acid class of inhibitors from AZD4017 (1) to the development candidate AZD8329 (27). A structural change from pyridine to pyrazole together with structural optimization led to an improved technical profile in terms of both solubility and pharmacokinetics.

Article Synopsis
  • 11β-HSD1 is a promising target for treating type II diabetes and metabolic syndrome.
  • Researchers optimized a series of 2-thioalkyl-pyridine inhibitors to improve their pharmacokinetic properties, leading to better bioavailability in rats and dogs.
  • A potential issue with reactive metabolites in one compound type was resolved by changing the sulfur group to a carbon group.

This article considers the legal status of so-called contracts for anonymity between fertility clinics and donors of gametes that were made in the period before legislation authorising disclosure. It notes that while clinics frequently cite the existence of these "contracts" to argue against retrospective legislation authorising disclosure of the donor's identity, they may be nothing more than one-sided statements of informed consent. However, the article notes that even if an agreement between a donor and a clinic is not contractual, it does not follow that a person conceived through assisted reproductive technology has any right of access to the identity of the donor.

The role of the tumour microenvironment and complex cellular interactions has attracted interest in responses to primary chemotherapy. Of particular interest are tumour-infiltrating T cells and tumour-infiltrating macrophages (TIMs). We evaluated TIMs and their key activation markers in patients with breast cancer undergoing primary chemotherapy related to response and survival.
