How to use a trust as an alternative to a will to transfer assets to the next generation? This article will answer this question by first introducing the reader to inheritance and trust law in Israel. It will explore the endowment and how it should be used in order to regulate the transfer of assets to the next generation—how a trust should be set up and how assets should be transferred to it. The conclusion drawn from this analysis points out the key elements which should be considered when creating a trust to survive death under Israeli law.

Trusts/foundations are a relatively new estate planning tool in Israel. As such, the Trust Law, passed in 1979, is basic legislation governing the principles of trust law. Together with the Tax Ordinance governing the taxation of trusts and court precedents, Israel trust practice is formed. Although, compared to extensive practices in other jurisdictions such as the UK or the USA, the trust practice in Israel is in its initial stages with much room to grow and expand. The factual basis and the necessity for establishing trusts lie in HNW families, social changes in the nuclear family and the need to care for the elderly and disabled. In addition, there is a growing practice of holding real estate via trust structures which remains to be resolved from a tax perspective as such structures are taxed under the Taxation of Real Property Law and not under the Tax Ordinance. This article will focus on several important legal issues involved in drafting and administering Israeli trusts/foundations; recognition of foreign trusts/foundations in Israel, the trustee's confidentiality obligation, and dispute resolution options for trusts.

The Israeli Foundation refers to the legal structure of an Israeli private trust, created in combination with an underlying company to hold the trust assets. This article will focus on this structure, as well as on the creation of the Israeli private trust by way of a deed (hekdesh) or by way of a contract. The article will continue by looking into the Israeli real estate trust, which is commonly created by a contract, and finally the article will explore the inheritance procedure in Israel and the issues arising from the conflict between the Trust Law, the Contracts Law, the Succession Law and the Gift Law.

This article provides an overview of the factors to be considered in order to structure and grow a family business in Israel.

This article will review the provisions of the Israeli Trust Law, 1979, as they refer to the trust settled by Hekdesh deed, a legal structure with certain similarities to foundations in some foreign jurisdictions. The Israeli trust is not a separate legal entity thereby requiring an underlying company in various circumstances. The Hekdesh together with the underlying company are referred to in this article as the ‘Israeli Foundation’.

SUMMARYMultiple ongoing clinical trials use site-specific nucleases to disrupt T cell receptor (TCR) genes in order to allow for allogeneic T cell therapy1–5. In particular, the first U.S. clinical trial using CRISPR-Cas9 entailed the targeted disruption of the TCR chains and programmed cell death protein 1 (PDCD1) in T cells of refractory cancer patients6. Here, we used the same guide RNA sequences and applied single-cell RNA sequencing (scRNAseq) to more than 7000 primary human T cells, transfected with CRISPR-Cas9. Four days post-transfection, we found a loss of chromosome 14, harboring the TCRα locus, in up to 9% of the cells, and a chromosome 14 gain in up to 1.4% of the cells. We further identified truncations of chromosome 7, harboring the TCRβ locus, in 9.9% of the cells. Loss of heterozygosity (LOH) was further validated using fluorescencein situhybridization (FISH) and the temporal dynamics of cleavage and incomplete repair were monitored using digital droplet PCR (ddPCR). Aneuploidy was found among all T cell subsets and was associated with transcriptional signatures of reduced proliferation and metabolism as well as with induced p53 activation and cell death. We conclude that aneuploidy and chromosomal truncations are frequent outcomes of CRISPR-Cas9 cleavage in clinical protocols. Monitoring and minimizing these aberrant products is crucial for future applications of genome editing in T cell engineering and beyond.

Background and aims Primary sclerosing cholangitis and inflammatory bowel disease are two associated, chronic inflammatory, pre-malignant conditions. We hypothesized that patients with these disorders may harbour telomere dysfunction as a marker of chromosomal instability. The aim of our study was to compare parameters of the telomere-telomerase system in these cohorts. Methods In this prospective study, peripheral blood was withdrawn from patients with primary sclerosing cholangitis (N = 20), inflammatory bowel disease (N = 20) and healthy controls (N = 20), and lymphocytes were isolated. Telomere length was quantified as a function of the signal intensity and telomere number. Random aneuploidy and telomere capture were determined by fluorescence in situ hybridization technique with specific probes. Results Patients with inflammatory bowel disease had higher measures of intestinal disease activity than patients with primary sclerosing cholangitis. Despite this, shorter telomere length and telomere aggregates, especially the fusion of 2–5 telomeres, were observed at significantly higher rate in patients with primary sclerosing cholangitis relative to inflammatory bowel disease or healthy controls. Rates of aneuploidy and telomere capture were higher in the two probes in both diseases compared to controls (p Conclusion Dysfunction of telomeres was demonstrated in primary sclerosing cholangitis patients more than inflammatory bowel disease and healthy controls patients, which attests to genetic instability and immunosenescence.

Introduction The intrauterine environment, including the placenta, is influenced by a variety of factors, among which is diabetes during pregnancy. These factors can affect lifetime morbidity. Senescence is a state of cellular metabolic arrest, known to be correlated with age-related diseases and is usually accompanied by short telomeres. This study evaluated telomere characteristics in placentas and in cord blood from term pregnancies complicated by uncontrolled diabetes mellitus. Methods Placental biopsies and cord blood were collected from 16 pregnancies with poorly controlled diabetes and from 16 healthy controls. Senescence-associated heterochromatin foci (SAHF) and senescence-associated β-galactosidase (SAβ-Gal) staining were evaluated. Apoptosis was evaluated using tunel staining. Telomere length and aggregate formation were assessed in placentas and in cord blood using Q-FISH. Results Increased SAHF (19.28% ± 7.93 vs. 7.78% ± 5.31, P

Primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD) are associated chronic inflammatory diseases with malignant potential. Loss of replication synchrony during the S-phase of the cell cycle has been shown to be linked to several malignant and premalignant states. This study evaluated temporal differences in replication timing between these diseases. The replication pattern of peripheral blood lymphocytes obtained from patients with PSC and IBD and healthy individuals was analyzed by fluorescence in situ hybridization (FISH) in 2 pairs of alleles, in 15qter and 13qter. Asynchrony was determined by the presence of 1 single and 1 set of double dots in the same cell. Samples from subjects with PSC showed significantly greater temporal differences in replication timing, in contrast to the high level of synchrony observed in samples from healthy individuals (p = 0.045). Samples from IBD patients exhibited a nonsignificant increase in replication asynchrony. We believe that these results reflect impairment in the replication control of structural homologous loci in PSC, and that this phenomenon may be correlated with the inflammation-induced malignant potential of this condition.

Senescence has been described as a stable cell proliferation arrest resulting from the progression of primary human fibroblasts through a finite number of population doublings in vitro. Accelerated telomere shortening was observed in pregnancies complicated by intrauterine growth restriction, in placentas of diabetic mothers and trisomy 21 amniocytes. We hypothesized that under conditions of stress, telomeres in placentas will be shorter and there will be more cells with the senescence phenotype.The two study groups included placental biopsies from 7 cases of trisomy 21 and amniocytes from 10 cases of trisomy 21. The control groups consisted of placental biopsies from 6 cases and amniocytes from 10 pregnancies with a normal karyotype. The samples were analyzed for the presence of senescent cells based on the number of fragments in each cell.A significantly higher percentage of cells in the senescent state, based on a higher percentage of cells with more fragmentations, were found in the amniocytes (20.8%) and in trophoblasts (94.3%) from placentas with trisomy 21 compared to the control groups.Among other genetic instability parameters, trisomy 21 amniocytes and trophoblasts express a higher prevalence of senescent cells than were previously reported.

Fetal cells represented by extravillous trophoblasts (EVT) obtained from the cervix by a minimally invasive procedure are important for prenatal diagnosis in early pregnancies. Endoreduplication is a duplication of chromosomes without mitosis, leading to polyploidy that might represent increased cellular metabolic activity. In this study, we estimated the normal prevalence of polyploid trophoblasts exfoliated to the cervix between 5 and 13 weeks of gestation.Cervical samples were obtained by cytobrush, between 5 and 13 weeks of gestation from 36 randomly selected, singleton pregnancies. FISH was done with X, Y and two 21 probes.We diagnosed 21 pregnancies with female and 15 pregnancies with male fetal karyotypes. A mean of 15.2 (0.02%) tetraploid cells were found in pregnancies with a female fetus and a mean of 2.0 (0.003%) tetraploid cells were found in pregnancies with a male fetus. The tetraploid cells (endoreduplicated trophoblasts) were two to three times larger than the normal cells usually seen in the cervix.Extravillus trophoblasts tend to form endoreduplication to the ploidy level of 4c-8c of DNA. Those cells may represent a typical phenomenon in the growing placenta. Extravillus trophoblasts from female fetuses tend to form higher rates of endoreduplication.

The increasing use of chromosomal microarray studies in patients with intellectual disability has led to the description of new microdeletion and microduplication syndromes. We report terminal microdeletions in 13q34 chromosome region in 5 adult patients of two unrelated families. Patients harboring 13q34 microdeletions display common clinical features, including intellectual disability, obesity, and mild facial dysmorphism. These individuals can become fairly self-sufficient, however they do not live independently, and require community and social support. Further systematic analysis of the genes comprised in the deleted region will allow the identification of genes whose haploinsufficiency is expected to lead to disease manifestations, in particular intellectual disability.

Objective. In this study, we applied the fluorescent in situ hybridization (FISH) technique and compared the common numerical abnormalities with chromosomes 13, 16, 18, 21, X, and Y in spontaneous to artificial abortion. This would cover about 75% of the common aneuploidy in spontaneous abortion. Methods. Placentas were taken from 59 patients with a first trimester spontaneous abortion and 61 patients who underwent an elective first trimester pregnancy termination. The range of growth was from 5 to 12 gestational weeks. Placentas were processed according to direct chorionic villi preparation. Direct dual color FISH was performed according to Vysis protocol with the probes for the following chromosomes: 13, 16, 18, 21, X, and Y. Results. The aneuploidy rate in spontaneous abortion was 55.9% and in artificial abortion 8.2%. There was a significant difference between the two groups in the aneuploidy rate ( P = 6 × 10 −9 ). Conclusion. FISH is a rapid, efficient, and relatively inexpensive tool in detecting a...

Objective Primary sclerosing cholangitis (PSC) is a chronic cholestatic disorder that involves inflammatory and fibrotic changes in the bile ducts. Up to 80% of patients have concomitant inflammatory bowel disease (IBD) with colitis. PSC patients are predisposed to develop hepatobiliary, colonic and other extrahepatic malignancies, probably related to inflammatory processes that might promote carcinogenesis. Telomerase is an enzyme complex that lengthens telomeres and has enhanced expression in numerous malignancies. In this study, we evaluated the TERC gene copy number, the proportion of cells in senescence and the amount of fragmentation in the senescent state. Methods Fluorescence in situ hybridization (FISH) for the TERC gene was applied to lymphocytes retrieved from PSC (N = 19), colitis (N = 20) and healthy control patients (N = 20) to determine the TERC copy number. On the same FISH slides, cells stained with DAPI were also analyzed for senescence-associated heterochromatin foci (SAHF) status, including the number of cells with fragments and the number of SAHF fragments in each cell. Results A higher TERC gene copy number was observed in cells from PSC patients compared to colitis and control group patients. It was also higher in the colitis than in the control group. Significantly more cells in the senescent state and more fragmentation in each cell were observed in the PSC group compared to colitis and control groups. Conclusion The TERC gene copy number and the number of cells in the senescent state were increased in PSC patients compared to the colitis and control groups. These findings are probably related to the genetic instability parameters that reflect the higher tendency of this patient group to develop malignancies.

Our rate of detected aneuploidy is compatible with other reports in which conventional cytogenetics was utilized.
