OBJECTIVE: To determine which parameters are correlated with transplanted kidney status in patients who have undergone kidney transplantation and can be used for early assessment of acute renal rejection. METHODS: The study included 16 patients with stable renal allografts (Group 1) and 37 patients with rejected allografts (Group 2), determined by renal biopsy post transplantation. All patients' kidneys were evaluated using diffusion-weighted MRI (DW-MRI), in which both clincal and MRI-derived biomarkers were integrated...

Alzheimer's disease (AD) is one of the most common neurodegenerative diseases that influences the central nervous system, often leading to dire consequences for quality of life. The disease goes through some stages mainly divided into early, moderate, and severe. Among them, the early stage is the most important as medical intervention has the potential to alter the natural progression of the condition. In practice, the early diagnosis is a challenge since the neurodegenerative changes can precede the onset of clinical symptoms by 10-15 years...

Early diagnosis is playing an important role in preventing progress of the Alzheimer's disease (AD). This paper proposes to improve the prediction of AD with a deep 3D Convolutional Neural Network (3D-CNN), which can show generic features capturing AD biomarkers extracted from brain images, adapt to different domain datasets, and accurately classify subjects with improved fine-tuning method. The 3D-CNN is built upon a convolutional autoencoder, which is pre-trained to capture anatomical shape variations in structural brain MRI scans for source domain...

Optical Coherence Topography (OCT) is an emerging biomedical imaging technology that offers non-invasive real-time, high-resolution imaging of highly scattering tissues. It is widely used in ophthalmology to perform diagnostic imaging on the structure of the anterior eye and the retina. Clinical studies are carried out to assess the application of OCT for some retinal diseases. OCT can provide means for early detection for various types of diseases because morphological changes often occur before the physical symptoms of these diseases...

BACKGROUND AND PURPOSE: An ever-growing wealth of information on current drugs and their pharmacological effects is available from online databases. As our understanding of systems biology increases, we have the opportunity to predict, model and quantify how drug combinations can be introduced that outperform conventional single-drug therapies. Here, we explore the feasibility of such systems pharmacology approaches with an analysis of the mevalonate branch of the cholesterol biosynthesis pathway...

Ghazal Kabbach, Debabrata Mukherjee
Pulmonary hypertension (PH) related to left heart disease (LHD) is the most common form of PH, accounting for more than two third of all PH cases. The hemodynamic abnormalities seen in PH-LHD are complex, and there are currently minimal evidence-based recommendations for the management of PH-LHD. While it is accepted that PH in the context of left heart disease is a marker of worse prognosis, it remains unclear whether its primary treatment is beneficial or harmful. In this article, we discuss the prevalence and significance of PH in patients with heart failure (HF) with reduced ejection fraction (HFrEF) as well as HF with preserved ejection fraction (HFpEF), and those with valvular heart disease and provide insights into the complex pathophysiology of cardiopulmonary interrelationship in individuals with PH due to left heart disease...

INTRODUCTION: The present study aimed to determine the incidence and anatomic variation of the middle mesial (MM) canal in mandibular permanent first molars using cone-beam computed tomographic imaging and to evaluate the association between the presence of MM canals and anatomic landmarks of the pulp chamber floor in the mesial root. METHODS: In this in vivo cross-sectional study, 210 CBCT scans of mandibular fist molars from 210 patients were included. CBCT scans were evaluated in 3 sections, and the following data were collected for further analysis: identification of the MM canal, the distance between the mesiobuccal (MB) and mesiolingual (ML) orifices, the presence of any isthmus between the MB and ML orifices, and the MB and ML root canal system (RCS) configurations...

JAA-F11 is a highly specific mouse monoclonal to the Thomsen-Friedenreich Antigen (TF-Ag) which is an alpha-O-linked disaccharide antigen on the surface of ~80% of human carcinomas, including breast, lung, colon, bladder, ovarian, and prostate cancers, and is cryptic on normal cells. JAA-F11 has potential, when humanized, for cancer immunotherapy for multiple cancer types. Humanization of JAA-F11, was performed utilizing complementarity determining regions grafting on a homology framework. The objective herein is to test the specificity, affinity and biology efficacy of the humanized JAA-F11 (hJAA-F11)...

Freshwater mussel species with doubly uniparental inheritance (DUI) of mtDNA are unique because they are naturally heteroplasmic for two extremely divergent mtDNAs with ~50% amino acid differences for protein-coding genes. The paternally-transmitted mtDNA (or M mtDNA) clearly functions in sperm in these species, but it is still unknown whether it is transcribed when present in male or female soma. In the present study, we used PCR and RT-PCR to detect the presence and expression of the M mtDNA in male and female somatic and gonadal tissues of the freshwater mussel species Venustaconcha ellipsiformis and Utterbackia peninsularis (Unionidae)...

Secreted reporter proteins are reliable modalities for monitoring of different biological processes, which can be measured longitudinally in conditioned medium of cultured cells or body fluids such as blood and urine, ex vivo. In this chapter, we will explore established secreted reporters and their applications and limitations for monitoring of promoter function. We will also describe both cell-based and blood-based assays for detecting three commonly used reporters: secreted alkaline phosphatase (SEAP ), Gaussia luciferase (Gluc), and Vargula luciferase (Vluc)...

Troponin is a specific cardiac infarction isoform (TnIc, TnTc) and its determination is used for the diagnosis of myocardial infarction even with normal Electrocardiography. The increase of cardiac troponins occurs in a variety of clinical situations without an acute coronary syndrome (ACS), cardiologists and emergency physicians are often confronted with positive troponins that are difficult to interpret. Few data exist about the occurrence, the clinical characteristics and the predictive value in case of absence of ACS...

Lipid exchange among citrem nanoparticles and an ethanol micellar solution containing soy phosphatidylcholine was investigated in situ by coupling small angle X-ray scattering with a microfluidic device. The produced soy phosphatidylcholine/citrem nanoparticles have great potential in the development of hemocompatible nanocarriers for drug delivery.

Nicotinamide adenine dinucleotide (NAD(+) ) is a ubiquitous metabolite that serves an essential role in the catabolism of nutrients. Recently there has been a surge of interest in NAD(+) biology, with the recognition that NAD(+) influences many biological processes beyond metabolism, including transcription, signalling and cell survival. There are a multitude of pathways involved in the synthesis and breakdown of NAD(+) , and alterations in NAD(+) homeostasis have emerged as a common feature of a range of disease states...

Transference Focused Psychotherapy for Borderline-Adolescents in a Day Clinic Treatment Program This paper focuses on the concept of transference focused psychotherapy (TFP) modified for juvenile borderline patients. Adolescents with borderline developmental personality disorder (bpd) have an essential deficit in their personality structure that leads to oscillations in their self-esteem and in a "split" perception of the world. They suffer from a variety of symptoms and severe impairments on their own and their families' quality of life...

An inescapable consequence of sex in eukaryotes is the evolution of a biphasic life cycle with alternating diploid and haploid phases. The occurrence of selection during the haploid phase can have far-reaching consequences for fundamental evolutionary processes including the rate of adaptation, the extent of inbreeding depression, and the load of deleterious mutations, as well as for applied research into fertilization technology. Although haploid selection is well established in plants, current dogma assumes that in animals, intact fertile sperm within a single ejaculate are equivalent at siring viable offspring...
