Abstract

A359 aluminum alloy composite containing 20 vol. % silicon carbide particles was remelted, and 100-mm diameter foam ingots were prepared using 0.75 wt. % of titanium hydride (TiH2). Three identical experiments each were carried out at two foaming temperatures (640 and 660 °C) to check the reproducibility of the cell structure and foam properties. Foams made at 640 °C were reproducible in terms of foam expansion, cell size and cell size variation along the ingot height. The property scatter, evaluated in terms of relative standard deviation, is similar for density and modulus of the foam. For compressive plastic strength, the scatter is double than for density. The density and mechanical properties are reproducible within these scatters. Foams prepared at 660 °C, on the other hand, suffered from liquid foam collapse during solidification and hence couldn't be qualified for detailed study of reproducibility. The collapse resulted in distortion of the foam ingot and elongated cell structures in other parts. However, the cell size and mechanical properties in the un-distorted region are comparable with those foamed at 640 °C. Overall, good quality cell structure and consistent mechanical properties could be obtained in foams processed at 640 °C. [ABSTRACT FROM AUTHOR]

Author

Ratna, Nikhil, Pasupulati, Swathi Lakshmi, Nadella, Ravi K., Purushottam, Meera, and Jain, Sanjeev

Abstract

Background: Huntington's Disease (HD) is an autosomal dominant, progressive neuropsychiatric illness caused by CAG repeat expansion. The high penetrance of the mutation and limited treatment options make it challenging for patients and caretakers. Proper counseling enables families to cope better and make informed life choices.Objective: To explore some complex issues in genetic counseling and testing (GCAT) in HD.Materials and Methods: Vignettes of patients who underwent genetic testing along with pre and post-test counseling at our GCAT clinic.Results: Case 1: Diagnosis of juvenile HD meant that the healthy parent was an obligate carrier of the mutation. Case 2: Consanguinity resulted in a dense prevalence of HD and >50% risk for the progeny. Case 3: Predictive testing in youth with healthy parents but affected uncles and aunts revealed a HD expansion.Conclusions: HD can present with complex inheritance patterns and proper counseling is necessary for better outcomes.

Subjects

Abstract

The implantation of high energy positively charged Titanium ions into p-type InP:Zn, at both room temperature and 200 degrees centigrade, and the calculation of range statistics revealed that Titanium did not redistribute during the post-implantation annealing except for a slight indiffusion, independent of the implant or annealing temperatures used. The range statistics were calculated using an analysis of the as-implanted profiles determined by secondary ion-mars spectroscopy. At higher ranges of MeV, Titanium implanted InP:Zn, the background Zinc showed a small degree of redistribution and buried layers with intrinsic resistivity were obtained.

Abstract

The feasibility of using high-energy transition-metal implants to obtain buried high resistance layers and compensate donor implant tails in indium phosphide is evaluated. Fe and Co implantations are performed into epitaxially-grown InP:Sn wafers at 200 degrees centigrade. The specimens are then subjected to secondary-ion-mass spectrometry, polaron electrochemical capacitance-voltage profiling and Rutherford backscattering analyses. Results show that aside from the implantation peak, the annealing process also generated additional peaks in the SIMS depth profiles.

Abstract

High energy MeV B compensation implants into n-type GaAs and InP were investigated. The results showed that the material did not become amorphous for any of the fluences used. Buried layers with high resistivities were obtained after heat treatments. GaAs featured breakdown voltages of 80 V while InP had 35 V. The yield in GaAs annealed samples was close to that of a virgin sample while InP yielded more than the as-implanted sample.

Abstract

High-energy (three mega electron volts) silicon implants and lower-energy (150 kilo electron volts) germanium implants were performed into indium phosphate:iron (InP:Fe) at 200 degrees celsius. The elevated temperature prevented amorphization, reduced lattice damage in the material and improved dopant activation and carrier mobility after annealing. Germanium implantation was found to be unsuitable even for creating n-type layers in InP:Fe.

Abstract

Objectives: Bipolar disorder (BD) is a neuropsychiatric disorder with a complex pattern of inheritance. Although many genetic studies have been conducted on BD, its genetic correlates remain uncertain. This study was aimed at identifying the genetic underpinnings of the disorder in an Indian family, which has been under comprehensive clinical evaluation and follow‐up for over 12 years. Methods: We analysed a four‐generation family with several of its members diagnosed for BD employing a combination of genetic linkage and exome analysis. Results: We obtained suggestive LOD score for a chromosome 1 and a chromosome 6 marker (D1S410; LOD = 3.01, Ө = 0; and D6S289; LOD = 1.58, Ө = 0). Manual haplotyping of the regions encompassing these two markers helped delimit a critical genomic interval of 32.44 Mb (D1S2700‐D1S435; chromosome 1p31.1‐13.2) and another of 10.34 Mb (D6S470‐D6S422; chromosome 6p22.3‐22.2). We examined the exomic sequences corresponding to these two intervals and found rare variants, NM_181712.4: c.2461G>T (p.Asp821Tyr) in KANK4 at 1p31.1‐13.2; and NM_006366:c.‐93G>A, in the 5' UTR of CAP2 at 6p22.3‐22.2. Conclusions: Our studysuggests involvement of KANK4 or CAP2 or both in BD in this family. Further analysis of these two genes in BD patients and functional evaluation of the allelic variants identified are suggested. [ABSTRACT FROM AUTHOR]

Abstract

Aim: Severe mental illnesses (SMI), such as bipolar disorder and schizophrenia, are highly heritable, and have a complex pattern of inheritance. Genome‐wide association studies detect a part of the heritability, which can be attributed to common genetic variation. Examination of rare variants with next‐generation sequencing may add to the understanding of the genetic architecture of SMI. Methods: We analyzed 32 ill subjects from eight multiplex families and 33 healthy individuals using whole‐exome sequencing. Prioritized variants were selected by a three‐step filtering process, which included: deleteriousness by five in silico algorithms; sharing within families by affected individuals; rarity in South Asian sample estimated using the Exome Aggregation Consortium data; and complete absence of these variants in control individuals from the same gene pool. Results: We identified 42 rare, non‐synonymous deleterious variants (~5 per pedigree) in this study. None of the variants were shared across families, indicating a 'private' mutational profile. Twenty (47.6%) of the variant harboring genes were previously reported to contribute to the risk of diverse neuropsychiatric syndromes, nine (21.4%) of which were of Mendelian inheritance. These included genes carrying novel deleterious variants, such as the GRM1 gene implicated in spinocerebellar ataxia 44 and the NIPBL gene implicated in Cornelia de Lange syndrome. Conclusion: Next‐generation sequencing approaches in family‐based studies are useful to identify novel and rare variants in genes for complex disorders like SMI. The findings of the study suggest a potential phenotypic burden of rare variants in Mendelian disease genes, indicating pleiotropic effects in the etiology of SMI. [ABSTRACT FROM AUTHOR]

Abstract

Background: Dysfunction in inwardly rectifying potassium channel Kir4.1 has been implicated in SeSAME syndrome, an autosomal-recessive (AR), rare, multi-systemic disorder. However, not all neurological, intellectual disability, and comorbid phenotypes in SeSAME syndrome can be mechanistically linked solely to Kir4.1 dysfunction. Methods: We therefore performed whole-exome sequencing and identified additional genetic risk-elements that might exert causative effects either alone or in concert with Kir4.1 in a family diagnosed with SeSAME syndrome. Results: Two variant prioritization pipelines based on AR inheritance and runs of homozygosity (ROH), identified two novel homozygous variants in KCNJ10and PI4KBand five rare homozygous variants in PVRL4, RORC, FLG2, FCRL1, NIT1and one common homozygous variant in HSPA6segregating in all four patients. The novel mutation in KCNJ10resides in the cytoplasmic domain of Kir4.1, a seat of phosphatidylinositol bisphosphate (PIP2) binding. The mutation altered the subcellular localization and stability of Kir4.1 in patient-specific lymphoblastoid cells (LCLs) compared to parental controls. Barium-sensitive endogenous K+currents in patient-specific LCLs using whole-cell patch-clamp electrophysiology revealed membrane depolarization and defects in inward K+ion conductance across the membrane, thereby suggesting a loss-of-function effect of KCNJ10variant. Conclusion: Altogether, our findings implicate the role of new genes in SeSAME syndrome without electrolyte imbalance and thereby speculate the regulation of Kir4.1 channel activity by PIP2 and integrin-mediated adhesion signaling mechanisms.

Abstract

OBJECTIVE: Circadian rhythm disruption is commonly observed in bipolar disorder (BD). Daylight is the most powerful signal to entrain the human circadian clock system. This exploratory study investigated if solar insolation at the onset location was associated with the polarity of the first episode of BD I. Solar insolation is the amount of electromagnetic energy from the Sun striking a surface area of the Earth.METHODS: Data from 7488 patients with BD I were collected at 75 sites in 42 countries. The first episode occurred at 591 onset locations in 67 countries at a wide range of latitudes in both hemispheres. Solar insolation values were obtained for every onset location, and the ratio of the minimum mean monthly insolation to the maximum mean monthly insolation was calculated. This ratio is largest near the equator (with little change in solar insolation over the year), and smallest near the poles (where winter insolation is very small compared to summer insolation). This ratio also applies to tropical locations which may have a cloudy wet and clear dry season, rather than winter and summer.RESULTS: The larger the change in solar insolation throughout the year (smaller the ratio between the minimum monthly and maximum monthly values), the greater the likelihood the first episode polarity was depression. Other associated variables were being female and increasing percentage of gross domestic product spent on country health expenditures. (All coefficients: P ≤ 0.001).CONCLUSION: Increased awareness and research into circadian dysfunction throughout the course of BD is warranted.
