Religion, Delinquency, and Drug Use: A Meta-Analysis

Contemporary research on adolescent involvement in religion and delinquency is generally traced to Hirschi and Stark’s 1969 study, titled ‘‘Hellfire and Delinquency.’’ Their study surprised many by reporting no significant relationship between religious involvement and delinquency. Subsequent replications provided mixed results, but multiple reviews, both traditional and systematic, found religious involvement to be inversely related to delinquency. However, meta-analysis of the relationship remains scant with only three studies published to date. To address this research need, we conducted a meta-analysis of 62 relevant studies over four decades, which provided 145 effect sizes from 193,656 adolescents. We examined six bivariate correlations between two, attitudinal and behavioral, measures of religious involvement (religiosity and church attendance) and three indicators of delinquent behavior (alcohol use, illicit drug use, and nondrug delinquency). Our meta-analysis results indicated an inverse relationship among all correlations (range: -.16 to -.22). Stated differently, the results of this meta-analysis confirmed that religious involvement is negatively related to delinquent behaviors, regardless of measurement characteristics. The implications of this finding for future research on religion and delinquency are discussed

Intestinal epithelial replacement by transplantation of cultured murine and human cells into the small intestine.

Adult intestinal epithelial stem cells are a promising resource for treatment of intestinal epithelial disorders that cause intestinal failure and for intestinal tissue engineering. We developed two different animal models to study the implantation of cultured murine and human intestinal epithelial cells in the less differentiated "spheroid" state and the more differentiated "enteroid" state into the denuded small intestine of mice. Engraftment of donor cells could not be achieved while the recipient intestine remained in continuity. However, we were able to demonstrate successful implantation of murine and human epithelial cells when the graft segment was in a bypassed loop of jejunum. Implantation of donor cells occurred in a random fashion in villus and crypt areas. Engraftment was observed in 75% of recipients for murine and 36% of recipients for human cells. Engrafted spheroid cells differentiated into the full complement of intestinal epithelial cells. These findings demonstrate for the first time successful engraftment into the small bowel which is optimized in a bypassed loop surgical model

LongT5: Efficient Text-To-Text Transformer for Long Sequences

Recent work has shown that either (1) increasing the input length or (2) increasing model size can improve the performance of Transformer-based neural models. In this paper, we present a new model, called LongT5, with which we explore the effects of scaling both the input length and model size at the same time. Specifically, we integrated attention ideas from long-input transformers (ETC), and adopted pre-training strategies from summarization pre-training (PEGASUS) into the scalable T5 architecture. The result is a new attention mechanism we call {\em Transient Global} (TGlobal), which mimics ETC's local/global attention mechanism, but without requiring additional side-inputs. We are able to achieve state-of-the-art results on several summarization tasks and outperform the original T5 models on question answering tasks.Comment: Accepted in NAACL 202

Abnormal synergistic gait mitigation in acute stroke using an innovative ankle–knee–hip interlimb humanoid robot: A preliminary randomized controlled trial

Abnormal spasticity and associated synergistic patterns are the most common neuromuscular impairments affecting ankle–knee–hip interlimb coordinated gait kinematics and kinetics in patients with hemiparetic stroke. Although patients with hemiparetic stroke undergo various treatments to improve gait and movement, it remains unknown how spasticity and associated synergistic patterns change after robot-assisted and conventional treatment. We developed an innovative ankle–knee–hip interlimb coordinated humanoid robot (ICT) to mitigate abnormal spasticity and synergistic patterns. The objective of the preliminary clinical trial was to compare the effects of ICT combined with conventional physical therapy (ICT-C) and conventional physical therapy and gait training (CPT-G) on abnormal spasticity and synergistic gait patterns in 20 patients with acute hemiparesis. We performed secondary analyses aimed at elucidating the biomechanical effects of Walkbot ICT on kinematic (spatiotemporal parameters and angles) and kinetic (active force, resistive force, and stiffness) gait parameters before and after ICT in the ICT-C group. The intervention for this group comprised 60-min conventional physical therapy plus 30-min robot-assisted training, 7 days/week, for 2 weeks. Significant biomechanical effects in knee joint kinematics; hip, knee, and ankle active forces; hip, knee, and ankle resistive forces; and hip, knee, and ankle stiffness were associated with ICT-C. Our novel findings provide promising evidence for conventional therapy supplemented by robot-assisted therapy for abnormal spasticity, synergistic, and altered biomechanical gait impairments in patients in the acute post-stroke recovery phase.

Vascular mitochondrial respiratory function: the impact of advancing age

Little is known about vascular mitochondrial respiratory function and the impact of age. Therefore, skeletal muscle feed arteries were harvested from young (33 ± 7 yr, n = 10), middle-aged (54 ± 5 yr, n = 10), and old (70 ± 7 yr, n = 10) subjects, and mitochondrial respiration as well as citrate synthase (CS) activity were assessed. Complex I (CI) and complex I + II (CI+II) state 3 respiration were greater in young (CI: 10.4 ± 0.8 pmol·s−1·mg−1 and CI+II: 12.4 ± 0.8 pmol·s−1·mg−1, P \u3c 0.05) than middle-aged (CI: 7 ± 0.6 pmol·s−1·mg−1 and CI+II: 8.3 ± 0.5 pmol·s−1·mg−1) and old (CI: 7.2 ± 0.4 pmol·s−1·mg−1 and CI+II: 7.6 ± 0.5 pmol·s−1·mg−1) subjects and, as in the case of complex II (CII) state 3 respiration, were inversely correlated with age [r = −0.56 (CI), r = −0.7 (CI+II), and r = 0.4 (CII), P \u3c 0.05]. In contrast, state 4 respiration and mitochondria-specific superoxide levels were not different across groups. The respiratory control ratio was greater in young (2.2 ± 0.2, P \u3c 0.05) than middle-aged and old (1.4 ± 0.1 and 1.1 ± 0.1, respectively) subjects and inversely correlated with age (r = −0.71, P \u3c 0.05). As CS activity was inversely correlated with age (r = −0.54, P \u3c 0.05), when normalized for mitochondrial content, the age-related differences and relationships with state 3 respiration were ablated. In contrast, mitochondrion-specific state 4 respiration was now lower in young (15 ± 1.4 pmol·s−1·mg−1·U CS−1, P \u3c 0.05) than middle-aged and old (23.4 ± 3.6 and 27.9 ± 3.4 pmol·s−1·mg−1·U CS−1, respectively) subjects and correlated with age (r = 0.46, P \u3c 0.05). Similarly, superoxide/CS levels were lower in young (0.07 ± 0.01) than old (0.19 ± 0.41) subjects and correlated with age (r = 0.44, P \u3c 0.05). Therefore, with aging, vascular mitochondrial respiratory function declines, predominantly as a consequence of falling mitochondrial content. However, per mitochondrion, aging likely results in greater mitochondrion-derived oxidative stress, which may contribute to age-related vascular dysfunction
