Automatic cell segmentation has various application potentials in cytometry and histometry. In this paper, an automatic cluster (touching) cell segmentation approach using the dominant contour feature points has been presented. Dominant feature points are the locations of indentation on the contour of the cluster. First, dominant feature points on the contour of the cluster are...

BTK modulates p73 activity to induce apoptosis independently of p53

Bruton’s tyrosine kinase (BTK) is a key component of B cell receptor signalling. Because of this, BTK plays an important role in cell proliferation and survival in various B cell malignancies. However, in certain contexts, BTK can also have tumour suppressor functions. We have previously shown that BTK activates the p53 transcriptional activity by binding to and phosphorylating...

The effect of thermal insulation pads on heat flux, physical effort and perceived exertion during endurance exercise in cool environments

To determine the effects of thermal insulation pads on clothing surface temperature, physical effort and perceived exertion during endurance exercise in cool environments two different pants (PCOOL, PINSUL) were designed: PCOOL (Insulation: 0.055 clo) was made of a thin base material while PINSUL (Insulation: 0.131 clo) featured additional insulation pads covering ~ 30% of its...

BACKGROUND: Drug resistance indexes (DRIs) quantify the cumulative impact of antimicrobial resistance on the likelihood that a given pathogen will be susceptible to antimicrobial therapy.

A comparative study on the validity and reliability of anterior, medial, and posterior approaches for internal fixation in the repair of fractures of the coronoid process of the ulna

The coracoid process plays an important role in maintaining the stability of the elbow joint. A fracture of the coronoid process is often treated via surgical approaches, including open reduction and internal fixation, which aim to regain a stable, flexible, and loadable joint. In this study, we compared the anterior, medial, and posterior approaches of internal fixation in the...

Spasmodic Torticollis—A Multicentre Study on Behavioural Aspects IV: Psychopathology

The GSI (General Symptom Index) of the Symptom Checklist 90 R (SCL 90 R) (as a global indicator of the severity of psychiatric symptoms) of 27% of the spasmodic torticollis (ST) sample fell outside the 95% range of the normal control group (two standard deviations). Patients with a higher GSI were younger, more functionally disabled and subject to higher psychosocial stress due...

Extracorporeal membrane oxygenation in aluminum phosphide poisoning in Nepal: a case report

Aluminum phosphide is a very common suicide agent in developing countries like Nepal. Due to the unavailability of a specific antidote, mortality is very high because the phosphine molecule that is formed leads to inhibition of the cytochrome oxidase enzyme system in mitochondria. Extracorporeal membrane oxygenation provides life-saving support to the cardiovascular and...

Hard photons in hadroproduction of top quarks with realistic final states

Abstract We present a complete description of top quark pair production in association with a hard photon in the dilepton channel. Our calculation is accurate to NLO in QCD. It is based on matrix elements for \( {e}^{+}{\nu}_e{\mu}^{-}{\overline{\nu}}_{\mu }b\overline{b}\upgamma \) production and includes all resonant and non-resonant diagrams, interferences, and off-shell...

Anatomy of the Episodic Buffer: A Voxel-Based Morphometry Study in Patients with Dementia

In 2000 Baddeley proposed the existence of a new component of working memory, the episodic buffer, which should contribute to the on-line maintenance of integrated memory traces. The author assumed that this component should be critical for immediate recall of a short story that exceeds the capacity of the phonological store. Accordingly, patients with Alzheimer’s dementia (AD...

Feasibility study on fixed flight-path angle descent for wide-body passenger aircraft

This study proposes the use of fixed flight-path angle (FPA) descent as a potential alternative for eco-friendly air traffic operations. Additionally, given that the proposed descent procedure follows a fixed, assigned flight-path angle, with the aircraft continuously descending toward the runway threshold with near-idle thrust, the trajectory should be more predictable for air...

Preventing Ischial Pressure Ulcers: III. Clinical Pilot Study of Chronic Neuromuscular Electrical Stimulation

Objective: BIONs™ (BIOnic Neurons) are injectable, wireless microstimulators that make chronic BION Active Seating (BAS) possible for pressure ulcer prevention (PUP). Neuromuscular electrical stimulation (NMES) produces skeletal motion and activates trophic factors, counteracting three major etiological mechanisms leading to pressure ulcers (PUs): immobility, soft-tissue atrophy...

Effects of positive end-expiratory pressure strategy in supine and prone position on lung and chest wall mechanics in acute respiratory distress syndrome

BackgroundIn acute respiratory distress syndrome (ARDS) patients, it has recently been proposed to set positive end-expiratory pressure (PEEP) by targeting end-expiratory transpulmonary pressure. This approach, which relies on the measurement of absolute esophageal pressure (Pes), has been used in supine position (SP) and has not been investigated in prone position (PP). Our...

The Feminist Library: “History is Herstory, Too”

The Feminist Library is not a typical public library; it is an organization with roots in the historical revolution. Its history, services, and classification system are unique; its collection is irreplaceable. The purpose of this study is to document the history, resources, and organization of the Feminist Library in London, England.

A Method for Determining Familial Cancer Risks in Clinical Practice

There is interest in estimating familial cancer risks in clinical practice for counselling and determining patients’ screening requirements. Empiric methods can be used to estimate an individual’s risk, however, every family history is unique making such methods relatively nonspecific. In contrast if an underlying genetic model can be assumed the risk of disease can be calculated...

Single-Item and Associative Working Memory in Stroke Patients

In this study, we examined working memory performance of stroke patients. A previous study assessing amnesia patients found deficits on an associative working memory task, although standard neuropsychological working memory tests did not detect any deficits. We now examine whether this may be the case for stoke patients as well. The current task contained three conditions: one...

Joint interference alignment and power allocation for NOMA-based multi-user MIMO systems

Interference alignment (IA) and non-orthogonal multiple access (NOMA) are key technologies for achieving the capacity scaling required by next generation networks to overcome the unprecedented growth of data network traffic. Each of these technologies was proved to present excellent performance for MIMO systems. In this article, we propose a joint IA and power allocation (PA...

Genotoxic and epigenotoxic effects in mice exposed to concentrated ambient fine particulate matter (PM 2.5 ) from São Paulo city, Brazil

The Metropolitan Area of São Paulo has a unique composition of atmospheric pollutants, and positive correlations between exposure and the risk of diseases and mortality have been observed. Here we assessed the effects of ambient fine particulate matter (PM2.5) on genotoxic and global DNA methylation and hydroxymethylation changes, as well as the activities of antioxidant enzymes...

The provision of urban green space and its accessibility: Spatial data effects in Brussels

Urban green space (UGS) has many environmental and social benefits. UGS provision and access are increasingly considered in urban policies and must rely on data and indicators that can capture variations in the distribution of UGS within cities. There is no consensus about how UGS, and their provision and access, must be defined from different land use data types. Here we...

Progressive Micrographia Shown in Horizontal, but not Vertical, Writing in Parkinson’s Disease

All published studies on micrographia, a diminution of letter size, examine handwriting in the horizontal direction. Writing horizontally typically requires increased wrist extension as handwriting progresses from left to right. Chinese characters, however, can be written not only horizontally from left to right, but also vertically from top to bottom. We examined the effect of...

Pertussis Immunization for Adolescents: What Are We Waiting for?

Immunization against pertussis (whooping cough) has been part of the routine childhood immunization program for over 50 years. Until 1997, a whole cell pertussis vaccine was used, most often combined with diphtheria and tetanus toxoids; in some jurisdictions it was combined with inactivated poliovirus vaccine and later with Haemophilus influenzae type b (Hib)-conjugate vaccine...

Combined explanations of B-physics anomalies: the sterile neutrino solution

Abstract In this paper we provide a combined explanation of charged- and neutral-current B-physics anomalies assuming the presence of a light sterile neutrino NR which contributes to the B → D(*)τν processes. We focus in particular on two simplified models, where the mediator of the flavour anomalies is either a vector leptoquark U 1 μ ∼ (3, 1, 2/3) or a scalar leptoquark S1...

Seasonal changes in dry matter yield from Karst pastures as influenced by morphoclimatic features

Pastures are strongly affected by local environmental variables in terms of their species richness, plant composition and herbage production. A multi-site monitoring study was conducted over three years to investigate the influence of morphoclimatic factors on the seasonal variations in dry matter (DM) yield from Karst pastures. Seven sites located on the Italian and Slovenian...
