Feasibility of Water Therapy for Slowing Autosomal Dominant Polycystic Kidney Disease Progression.

Key Points: Water therapy in autosomal dominant polycystic kidney disease (ADPKD) reduces urine osmolality and serum copeptin level, a marker of vasopressin activity. Water therapy reduces the ADPKD kidney growth rate indicating it is slowing disease progression. Patients with ADPKD are less likely to report pain on water therapy.

Comparative sequence analysis of pPATH pathogenicity plasmids in gall-forming bacteria.

Acquisition of the pathogenicity plasmid pPATH that encodes a type III secretion system (T3SS) and effectors (T3Es) has likely led to the transition of a non-pathogenic bacterium into the tumorigenic pathogen . pv. () forms galls on gypsophila () and triggers immunity on sugar beet (), while pv.

A 10-year comparison of short versus long-term court-ordered psychiatric hospitalization: a follow-up study.

Background: The Israel Mental Health Act of 1991 stipulates a process for court-ordered involuntary psychiatric hospitalization. As in many Western countries, this process is initiated when an individual is deemed "not criminally responsible by reason of mental disorder (NCR-MD)" or "incompetent to stand trial (IST)." A patient thus hospitalized may be discharged by the district psychiatric committee (DPC).

Macrophage-Secreted CSF1 Transmits a Calorie Restriction-Induced Self-Renewal Signal to Mammary Epithelial Stem Cells.

Calorie restriction enhances stem cell self-renewal in various tissues, including the mammary gland. We hypothesized that similar to their intestinal counterparts, mammary epithelial stem cells are insulated from sensing changes in energy supply, depending instead on niche signaling. The latter was investigated by subjecting cultures of mammary epithelial stem cells for 8 days to in vivo paracrine calorie-restriction signals collected from a 4-day-conditioned medium of individual mammary cell populations.

A common intronic single nucleotide variant modifies PKD1 expression level.

Autosomal dominant polycystic kidney disease (ADPKD), caused by mutations in PKD1 and PKD2 (PKD1/2), has unexplained phenotypic variability likely affected by environmental and other genetic factors. Approximately 10% of individuals with ADPKD phenotype have no causal mutation detected, possibly due to unrecognized risk variants of PKD1/2. This study was designed to identify risk variants of PKD genes through population genetic analyses.

Intramammary rapamycin administration to calves induces epithelial stem cell self-renewal and latent cell proliferation and milk protein expression.

Mammary epithelial stem cells differentiate to create the basal and luminal layers of the gland. Inducing the number of differentiating bovine mammary stem cells may provide compensating populations for the milk-producing cells that die during lactation. Inhibition of mTOR activity by rapamycin signals self-renewal of intestinal stem cells, with similar consequences in the mouse mammary gland and in bovine mammary implants maintained in mice.

An antibacterial T6SS in Pantoea agglomerans pv. betae delivers a lysozyme-like effector to antagonize competitors.

The type VI secretion system (T6SS) is deployed by numerous Gram-negative bacteria to deliver toxic effectors into neighbouring cells. The genome of Pantoea agglomerans pv. betae (Pab) phytopathogenic bacteria contains a gene cluster (T6SS1) predicted to encode a complete T6SS.

Deployed Deep Learning Kidney Segmentation for Polycystic Kidney Disease MRI.

This study develops, validates, and deploys deep learning for automated total kidney volume (TKV) measurement (a marker of disease severity) on T2-weighted MRI studies of autosomal dominant polycystic kidney disease (ADPKD). The model was based on the U-Net architecture with an EfficientNet encoder, developed using 213 abdominal MRI studies in 129 patients with ADPKD. Patients were randomly divided into 70% training, 15% validation, and 15% test sets for model development.

Newly characterized bovine mammary stromal region with epithelial properties supports representative epithelial outgrowth development from transplanted stem cells.

Limited outgrowth development of bovine mammary epithelial stem cells transplanted into de-epithelialized mouse fat pads restricts advanced studies on this productive organ's development and renewal. We challenged the mouse-bovine incompatibility by implanting parenchymal adjacent or distant bovine stromal layers (close and far stroma, respectively) into the mouse fat pad to serve as an endogenous niche for transplanted stem cells. The close stroma better supported stem cell take rate and outgrowth development.

Semi-Automated 3D Volumetric Renal Measurements in Polycystic Kidney Disease Using b0-Images-A Feasibility Study.

Autosomal dominant polycystic kidney disease (ADPKD) eventually leads to end stage renal disease (ESRD) with an increase in size and number of cysts over time. Progression to ESRD has previously been shown to correlate with total kidney volume (TKV). An accurate and relatively simple method to perform measurement of TKV has been difficult to develop.

Effect of Plant Systemic Resistance Elicited by Biological and Chemical Inducers on the Colonization of the Lettuce and Basil Leaf Apoplast by .

Mitigation strategies to prevent microbial contamination of crops are lacking. We tested the hypothesis that induction of plant systemic resistance by biological (induced systemic resistance [ISR]) and chemical (systemic acquired resistance [SAR]) elicitors reduces endophytic colonization of leaves by Salmonella enterica serovars Senftenberg and Typhimurium. .

Comparable reliability and acceptability of telepsychiatry and face-to-face psychiatric assessments in the emergency room setting.

Objective: This study aims to compare the reliability and acceptability of psychiatric interviews using telepsychiatry and face-to-face modalities in the emergency room setting.

Methods: In this prospective observational feasibility study, psychiatric patients ( = 38) who presented in emergency rooms between April and June 2020, went through face-to-face and videoconference telepsychiatry interviews in a non-randomised varying order. Interviewers and a senior psychiatry resident who observed both interviews determined diagnosis, recommended disposition and indication for involuntary admission.

Prevalence of Inferior Vena Cava Compression in ADPKD.

Introduction: Kidney and liver cysts in autosomal dominant polycystic kidney disease (ADPKD) can compress the inferior vena cava (IVC), but IVC compression prevalence and its risk factors are unknown.

Methods: Patients who have ADPKD (n = 216) with abdominal magnetic resonance imaging (MRI) studies and age-/sex-matched controls (n = 216) were evaluated for IVC compression as well as azygous vein diameter (a marker of collateral blood flow) and IVC aspect ratio (left-to-right dimension divided by anterior-to-posterior dimension with a value of 1 corresponding to a circular (high pressure) IVC caudal to compression.

Results: Severe IVC compression (≥70%) was observed in 33 (15%) ADPKD subjects and mild compression (≥50% to <70%) was observed in 33 (15%) subjects; whereas controls had no IVC compression ( < 0.

Hemorrhagic Cysts and Other MR Biomarkers for Predicting Renal Dysfunction Progression in Autosomal Dominant Polycystic Kidney Disease.

Background: Screening for rapidly progressing autosomal dominant polycystic kidney disease (ADPKD) is necessary for assigning and monitoring therapies. Height-adjusted total kidney volume (ht-TKV) is an accepted biomarker for clinical prognostication, but represents only a small fraction of information on abdominal MRI.

Purpose: To investigate the utility of other MR features of ADPKD to predict progression.

H2AX Promoter Demethylation at Specific Sites Plays a Role in STAT5-Induced Tumorigenesis.

Deregulated STAT5 activity in the mammary gland of transgenic mice results in parity-dependent latent tumorigenesis. The trigger for cell transformation was previously associated with hyperactivation of the H2AX proximal promoter in a small basal cell population during pregnancy. The current study focuses on the latent activation of tumor development.

Commentary: seclusion and mechanical restraint of psychiatric patients in Israel - an update.

Recently, Miodownik et al. reported in this journal the results of a study on seclusion and mechanical restraint of psychiatric patients in Israel (Isr J Health Policy Res 8:9, 2019). The study was a retrospective examination over a year of one inpatient ward in a psychiatric hospital.

Spleen phenotype in autosomal dominant polycystic kidney disease.

Aim: To evaluate splenic phenotype in autosomal dominant polycystic kidney disease (ADPKD) including presence of cysts and splenomegaly to determine if these are ADPKD related or represent unrelated incidental findings.

Materials And Methods: The axial/coronal T2-weighted images of ADPKD patients (n=215) and age/gender-matched controls (n=215) were evaluated for the presence of T2-bright splenic lesions by three blinded observers. Spleen volume (SV) was evaluated in the context of clinical and imaging features as well as results of gene testing for PKD1 and PKD2 mutations.

[THE EFFICACY OF THE DECISIONS OF TREATING PHYSICIANS VS. DISTRICT PSYCHIATRIC COMMITTEES IN REGARD TO THE DISCHARGE OF COMMITTED PSYCHIATRIC PATIENTS: A REGIONAL STUDY].

Background: The Israel Mental Health Act of 1991 stipulates a process for involuntary psychiatric hospitalization (IPH). A patient thus hospitalized can be discharged by either the treating psychiatrist (TP) or the district psychiatric committee (DPC). The decision rendered by the DPC is often at odds with the recommendation of the TP.

Calorie restriction and rapamycin administration induce stem cell self-renewal and consequent development and production in the mammary gland.

Expansion of the mammary epithelial stem cell pool holds promise for consequent mammary gland development and production. Complementary analyses of bovine mammary implants maintained in de-epithelialized mouse mammary fat pad and endogenous mouse mammary gland were performed to elucidate the effect of calorie restriction (CR) on stem cell self-renewal. CR elevated propagation rate and non-adherent mammosphere generation in cultured bovine mammary cells.

Psychopathology of Israeli Soldiers Presenting to a General Hospital Emergency Department: Lessons for the Attending Physician and Psychiatrist.

Background: There is scant research on the psychopathology of Israeli soldiers who present to a general hospital emergency department (ED).

Objectives: To assess the psychopathology among a cohort of Israeli soldiers who presented to a general hospital ED for mental health assessment.

Methods: The demographic and clinical characteristics of 124 consecutive soldiers who presented to the ED for psychiatric assessment between January 2008 and September 2012 were reviewed.

High Expression of CD200 and CD200R1 Distinguishes Stem and Progenitor Cell Populations within Mammary Repopulating Units.

Aiming to unravel the top of the mammary epithelial cell hierarchy, a subset of the CD49fCD24 mammary repopulating units (MRUs) was identified by flow cytometry, expressing high levels of CD200 and its receptor CD200R1. These MRU repopulated a larger area of de-epithelized mammary fat pads than the rest of the MRUs, termed MRU. MRU maintained a much lower number of divergently defined, highly expressed genes and pathways that support better cell growth, development, differentiation, and progenitor activity than their MRU counterparts.

A comparison of decisions to discharge committed psychiatric patients between treating physicians and district psychiatric committees: an outcome study.

Background: The Israel Mental Health Act of 1991 stipulates a process for involuntary psychiatric hospitalization (IPH). A patient thus hospitalized may be discharged by either the treating psychiatrist (TP) or the district psychiatric committee (DPC). The decision rendered by the DPC is often at odds with the recommendation of the TP.
