Jie Yang, Yoosun Chu, Mary Anne Salmon
Background and Objectives: Older lesbian, gay, bisexual, and transgender (LGBT) adults are more likely to live alone and less likely to have children compared with their heterosexual counterparts. The lack of immediate family system can render older LGBT adults particularly vulnerable to social isolation and its consequences. The current study utilizes social exclusion theory, which asserts that not only material resources but also engagement with and inclusion into the society are necessary for marginalized people to be integrated into the mainstream...

In post-conflict settings, service coverage indices are unlikely to be sustained if health systems are built on weak and unstable inter-organization networks-here referred to as infrastructure. The objective of this study was to assess the inter-organization infrastructure that supports the provision of selected health services in the reconstruction phase after conflict in northern Uganda. Applied social network analysis was used to establish the structure, size and function among organizations supporting the provision of (1) HIV treatment, (2) maternal delivery services and (3) workforce strengthening...

Antibiotic tolerance and persistence are often associated with treatment failure and relapse, yet are poorly characterized. In distinction from resistance, which is measured using the minimum inhibitory concentration metric, tolerance and persistence values are not currently evaluated in the clinical setting, and so are overlooked when a course of treatment is prescribed. In this article, we introduce a metric and an automated experimental framework for measuring tolerance and persistence. The tolerance metric is the minimum duration for killing 99% of the population, MDK99, which can be evaluated by a statistical analysis of measurements performed manually or using a robotic system...

The photonegative response to light stimulation in Rhodnius prolixus (Reduviidae, Triatominae) is modulated by compound eyes and ocelli. Screening pigments in the visual system have been shown to protect the cellular structures from the oxidative stress damage produced by blood ingestion and light stimulation. Red-eyed mutants of Rhodnius prolixus lack screening pigments in their compound eyes and ocelli and are exposed to more oxidative stress. Experiments with Rhodnius prolixus and Triatoma infestans red-eyed mutants reared from the first nymphal stage show damage in the retinas of the compound eyes and a decrease in photonegative responses due to light stimulation...

Cellular potassium import systems play a fundamental role in osmoregulation, pH homeostasis and membrane potential in all domains of life. In bacteria, the kdp operon encodes a four-subunit potassium pump that maintains intracellular homeostasis, cell shape and turgor under conditions in which potassium is limiting. This membrane complex, called KdpFABC, has one channel-like subunit (KdpA) belonging to the superfamily of potassium transporters and another pump-like subunit (KdpB) belonging to the superfamily of P-type ATPases...

In United States, 26% of greenhouse gas emissions is emitted from the transportation sector, which meanwhile accompanies with enormous toxic emissions to humans, such as CO, NOx, and HC, approximately 2.5% and 2.44% of a total exhaust emission for a petrol and diesel engine, respectively. These exhaust emissions are typically subject to vehicles' intermittent operations, such as hard acceleration and hard braking. In practice, drivers are inclined to operate intermittently while driving through a weaving segment, due to complex vehicle maneuvering for weaving...

The ability to characterize chemical heterogeneity in biological structures is essential to understanding cellular level function in both healthy and diseased states, but these variations remain difficult to assess using a single analytical technique. While mass spectrometry (MS) provides sufficient sensitivity to measure many analytes from volume-limited samples, each type of mass spectrometric analysis uncovers only a portion of the complete chemical profile of a single cell. Matrix-assisted laser desorp-tion/ionization (MALDI) MS and capillary electrophoresis electrospray ionization (CE-ESI)-MS are complementary analytical platforms frequently utilized for single cell analysis...

In the medical biology, it is essential to understand not only biological morphology but also the interaction between biological materials and agents. To study these, electron microscopy (EM) is often utilized. However, sample preparation techniques for EM require a high level of skill and a considerable time. Here, we conducted EM using a simple technique employing a conductive liquid, BEL-1, and compared the results with another simple technique employing an ionic liquid, 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF4 ])...

Vascular anomalies represent a heterogeneous group of pathologies of the circulatory system that can affect any type of hematic and /or lymphatic vessel of different diameter or anatomic site. The extreme variability of tissue types and districts involved by these lesions determines a wide heterogeneity of clinical manifestations, resulting in involvement of different medical expertise. In this context, a commonly agreed terminology is crucial for the appropriate evaluation and multidisciplinary management of patients...

Coding mutations in TTR gene cause a rare hereditary form of systemic amyloidosis, which has a complex genotype-phenotype correlation. We investigated the role of non-coding variants in regulating TTR gene expression and consequently amyloidosis symptoms. We evaluated the genotype-phenotype correlation considering the clinical information of 129 Italian patients with TTR amyloidosis. Then, we conducted a re-sequencing of TTR gene to investigate how non-coding variants affect TTR expression and, consequently, phenotypic presentation in carriers of amyloidogenic mutations...

In this paper, a cell selection technique for millimeter-wave (mm-wave) cellular systems with hybrid beamforming is proposed. To select a serving cell, taking into account hybrid beamforming structures in a mm-wave cellular system, the angles of arrival and departure for all candidate cells need to be estimated in the initialization stage, requiring a long processing time. To enable simultaneous multi-beam transmissions in a multi-cell environment, a cell and beam synchronization signal (CBSS) is proposed to carry beam IDs in conjunction with cell IDs...
