Anti-Tat immunity defines CD4 T-cell dynamics in people living with HIV on long-term cART.

EBioMedicine 2021 Mar 30:103306. Epub 2021 Mar 30.

National HIV/AIDS Research Center, Istituto Superiore di Sanità, Viale Regina Elena 299, Rome 00161, Italy. Electronic address:

Background: Low-level HIV viremia originating from virus reactivation in HIV reservoirs is often present in cART treated individuals and represents a persisting source of immune stimulation associated with sub-optimal recovery of CD4 T cells. The HIV-1 Tat protein is released in the extracellular milieu and activates immune cells and latent HIV, leading to virus production and release. However, the relation of anti-Tat immunity with residual viremia, persistent immune activation and CD4 T-cell dynamics has not yet been defined. Read More

Reduced Animal Models Fitting Only Equations for Phenotyped Animals.

Front Genet 2021 22;12:637626. Epub 2021 Mar 22.

AL Rae Centre for Genetics and Breeding, School of Agriculture, Massey University, Palmerston North, New Zealand.

Reduced models are equivalent models to the full model that enable reduction in the computational demand for solving the problem, here, mixed model equations for estimating breeding values of selection candidates. Since phenotyped animals provide data to the model, the aim of this study was to reduce animal models to those equations corresponding to phenotyped animals. Non-phenotyped ancestral animals have normally been included in analyses as they facilitate formation of the inverse numerator relationship matrix. Read More

Functional endurance capacity is associated with multiple other physical fitness components in 7-14-year-olds: a cross-sectional study.

BMC Public Health 2021 Apr 7;21(1):669. Epub 2021 Apr 7.

Department of Primary Teacher Education, Faculty of Educational Sciences, University of Pula, Pula, Croatia.

Background: Although evidence suggests that functional endurance capacity is the most important component associated with future health, little is known of how it is associated with multiple other physical fitness components. Since various physical fitness aspects do not change the same as functional endurance capacity during childhood, it is necessary to establish possible associations between functional endurance capacity and other physical fitness components in children. Therefore, the main purpose of the study was to test the associations between functional endurance capacity with other physical fitness components in 7-14-year-old children, stratified by gender.

Quantile regression models for survival data with missing censoring indicators.

Stat Methods Med Res 2021 Apr 7:962280221995986. Epub 2021 Apr 7.

Clinical and Public Health Sciences, Social and Scientific Systems, Durham, NC, USA.

The quantile regression model has increasingly become a useful approach for analyzing survival data due to its easy interpretation and flexibility in exploring the dynamic relationship between a time-to-event outcome and the covariates. In this paper, we consider the quantile regression model for survival data with missing censoring indicators. Based on the augmented inverse probability weighting technique, two weighted estimating equations are developed and corresponding easily implemented algorithms are suggested to solve the estimating equations.

The Impact of Longitudinal Surveillance on Tumor Thickness for Melanoma-Prone Families with and without Pathogenic Germline Variants of and .

Cancer Epidemiol Biomarkers Prev 2021 Apr;30(4):676-681

Division of Cancer Epidemiology and Genetics, NCI, NIH, Rockville, Maryland.

Background: Skin cancer screening is routinely performed for members of melanoma-prone families, but longitudinal studies evaluating the efficacy of surveillance in this high-risk population are lacking.

Methods: We evaluated thickness for first primary melanomas diagnosed in melanoma-prone families (≥2 individuals with melanoma) enrolled in NCT00040352 (NCI familial melanoma study) from 1976 through 2014; enrolled patients received routine skin cancer screening and education about skin self-exams. We used linear and ordinal logistic regression models adjusted for gender and age with a generalized estimating equations approach to report changes in thickness and tumor (T) stage over time, comparing outcomes for NCI cases diagnosed before (pre-study) versus after study participation (prospective) and for NCI cases versus nonfamilial cases [Surveillance, Epidemiology, and End Results (SEER) 9 registries].

Sports (Basel) 2021 Mar 16;9(3). Epub 2021 Mar 16.

Department of Physical Therapy-Program in Exercise Science, Marquette University, Milwaukee, WI 53233, USA.

The purpose of the current study was to compare the ability of five different methods to estimate eccentric-concentric and concentric-only bench-press 1RM from load-velocity profile data. Smith machine bench-press tests were performed in an eccentric-concentric ( = 192) and a concentric-only manner ( = 176) while mean concentric velocity was registered using a linear position transducer. Load-velocity profiles were derived from incremental submaximal load (40-80% 1RM) tests. Read More

Practical Prediction Models of Tensile Strength and Reinforcement-Concrete Bond Strength of Low-Calcium Fly Ash Geopolymer Concrete.

Polymers (Basel) 2021 Mar 12;13(6). Epub 2021 Mar 12.

Key Laboratory of Deep Underground Science and Engineering (Ministry of Education), Department of Architecture and Environment, Sichuan University, Chengdu 610065, China.

There have been a few attempts to develop prediction models of splitting tensile strength and reinforcement-concrete bond strength of FAGC (low-calcium fly ash geopolymer concrete), however, no model can be used as a design equation. Therefore, this paper aimed to provide practical prediction models. Using 115 test results for splitting tensile strength and 147 test results for bond strength from experiments and previous literature, considering the effect of size and shape on strength and structural factors on bond strength, this paper developed and verified updated prediction models and the 90% prediction intervals by regression analysis.

Muscle Length of the Hamstrings Using Ultrasonography Versus Musculoskeletal Modelling.

J Funct Morphol Kinesiol 2021 Mar 12;6(1). Epub 2021 Mar 12.

Laboratory of Neuromechanics, Department of Physical Education and Sport Sciences at Serres, Aristotle University of Thessaloniki, 62100 Serres, Greece.

Muscle morphology is an important contributor to hamstring muscle injury and malfunction. The aim of this study was to examine if hamstring muscle-tendon lengths differ between various measurement methods as well as if passive length changes differ between individual hamstrings. The lengths of biceps femoris long head (BFlh), semimembranosus (SM), and semitendinosus (ST) of 12 healthy males were determined using three methods: Firstly, by identifying the muscle attachments using ultrasound (US) and then measuring the distance on the skin using a flexible ultrasound tape (TAPE-US).
